Description

  The present invention relates to a sliding door flip-up suppressing member that suppresses the sliding door jumping up at the start of an assist operation by the sliding door slide assist device.

  Conventionally, a door closer (slide assist device) as described in Patent Document 1 is known. This door closer is provided for a sliding door, and is configured to assist the opening / closing operation by the biasing force of a pulling spring that is in an extended state when the sliding door that has been once opened or closed is closed or opened. When a force is applied to the sliding door in the closing direction so as to close the sliding door once opened, the biasing force of the extended tension spring acts, and the sliding door can be very lightly closed by the biasing force of the tension spring. it can.

  Specifically, the door closer includes a main body attached to the upper end side of the sliding door, a pulling spring that is housed in a free state in the main body, and an upper portion that is attached to the free end of the pulling spring. And a hook body (receiving member) provided in a manner protruding downward on the door frame, and the catch body and the hook body are vertically engaged with the sliding door opening operation. When the pulling spring is extended by a predetermined amount, the hook body is stopped and held by the main body body, and the catch body and the hook body are reengaged with the sliding door closing operation, and the stop holding state of the catch body is released and the pulling spring is released. It is configured to assist the sliding of the sliding door in the closing direction with the elastic contraction force.

JP 2008-156851 A

  By the way, in the door closer of the said patent document 1, when the sliding member and the receiving member engaged up and down, the upper edge part of the sliding door was braked, and, thereby, the sliding door might jump up.

  In addition, the present inventor proposes a sliding assist device for a sliding door that engages the sliding member and the receiving member in the lateral direction, that is, the side of the sliding door, instead of engaging the sliding member and the receiving member up and down. However, even in this type of sliding door slide assist device, for example, the height of one side of the sliding door is increased by using a height adjustment mechanism of the sliding door so that the sliding door moves in the sliding direction. In the case of tilting, the relative positional relationship between the slide member and the receiving member is also tilted accordingly. It turned out that it might jump up.

  Here, a member that fills the gap between the sliding door and the door frame may be interposed to suppress the flip-up, but there are various gaps, and the flip-up that fits into each of the gaps is wide. Providing a plurality of types of suppression members leads to an increase in cost. In addition, this flip-up suppressing member is attached to the door frame from the viewpoint of improving the appearance.For example, in the case of a slide assist device that assists sliding in the closing direction, the sliding door is slid in the closing direction to slide the sliding member and the receiving member. There is a problem that it is necessary to position the flip-up member above the end in the closing direction of the sliding door when the two are engaged, and the alignment is troublesome.

  The present invention has been made to solve such a conventional problem, and it is possible to easily and surely suppress the flipping up of the sliding door provided with the sliding assist device of the sliding door, and to easily mount the sliding door. The object is to provide a flip-up suppressing member.

  In order to solve the above-mentioned problem, a sliding door flip-up suppressing member according to the present invention includes a frame provided at the top of a sliding door that opens and closes an opening of a structure, and one end accommodated in the frame in a free state. A pulling spring, a slide member attached to the free end of the pulling spring, and a receiving member attached to the structure and engaged with the slide member within a predetermined range within the moving range of the sliding door. When the sliding door is slid in one direction, the sliding member and the receiving member are engaged to extend the pulling spring, and when the sliding door is slid in the opposite direction, the sliding member and the receiving member are engaged. A sliding member at the time of sliding in the opposite direction of a sliding door provided with a slide assist device that applies a biasing force of a spring to the sliding door as a sliding assist force in an opening direction or a closing direction A sliding-up restraining member for the sliding door that restrains the flip-up at the time of engagement with the receiving member, and is fixed to the structure side between the top of the sliding door and the structure, and is attached to and detached from the base One or a plurality of thin layer plate pieces that can be stacked, and the base is formed longer than an assist length by the slide assist device (claim 1). ).

  In this invention, the assist length by the slide assist device means that the sliding door is extended in advance near the end point of the sliding operation in one direction of the sliding door (specifically, slightly before the sliding door is opened or closed). This is the moving distance of the sliding door from the start to the end point when the movement is assisted by the urging force of the pulling spring.

  According to the present invention, since the base and one or a plurality of thin-layer plate pieces that are detachably stacked on the base are provided, the sliding door is tilted by using, for example, a height adjustment mechanism of the door pulley. Even if there is a gap between the sliding door and the structure, the number of laminated thin plate pieces can be arbitrarily stacked on the base according to the gap size, and the thickness can be reduced according to the gap. The gap can be filled easily and reliably by adjusting the number of layer plate pieces. For this reason, even when the sliding door is slid up due to braking of the upper portion of the sliding door when the sliding member and the receiving member are engaged when the sliding door slides in the opposite direction, the base and the thin layer plate piece Since the gap between the structure and the sliding door is filled, the jumping up of the sliding door can be easily and reliably suppressed.

  In addition, since the base is formed longer than the assist length by the slide assist device, one end of the base is abutted against, for example, a closing (opening) side end surface of the guide groove of the sliding door in the door frame. By aligning with the position corresponding to the closed (or open) position of the sliding door, the other end of the base can be reliably positioned above one end of the sliding door when the slide assist is started. For this reason, when mounting the base to the structure, it is not necessary to align the base in consideration of the engagement start position of the slide member and the receiving member in the slide assist device, and one end of the base is By simply adjusting to a predetermined position (a position corresponding to the closed or open position of the sliding door), it is possible to reliably prevent the sliding door from jumping up when the two members are engaged. That is, according to this invention, the flip-up suppressing member for the sliding door can be easily and effectively mounted.

  In this invention, although the said base may be formed in the shape of a guide rail for guiding the frame provided in the block shape or the sliding door or the sliding door, the said base is plate-shaped. Preferably, it is formed (Claim 2).

  In other words, there are sliding doors that open and close the opening of the structure by being guided along the guide groove of the door in the door frame, but when the base is formed in a plate shape as described above If the gap between the sliding door and the top of the guide groove is narrow, the plate-shaped base alone can be used to improve the usability. it can.

  In this invention, although the specific structure of the base is not particularly limited, the base is provided with a through hole for fixing the base to the structure side, and the thin base. The layer plate piece is preferably provided with an insertion hole at a position corresponding to the through hole.

  With this configuration, in a state where a predetermined number of thin layer plate pieces are stacked on the base, screws are inserted into the insertion holes of the thin layer plate pieces and the through holes of the base and screwed to the structure. Thus, the flip-up restraining member of the sliding door is fixed to the structure. As described above, by penetrating the through hole in the base and by forming the insertion hole facing the through hole in the thin layer plate piece, the workability of the work of attaching the flip-up suppressing member to the structure is improved. can do.

  In the present invention, the specific structure of the thin layer plate pieces, in particular, the connection between the thin layer plate pieces and the connection structure between the thin layer plate pieces and the base are not particularly limited. The thin plate member may be in a sliding contact state with at least one coupling protrusion provided on one surface side and the coupling protrusion recessed on the other surface side. It is preferable that at least one coupling recessed portion set in a shape that can be fitted is provided, and the base includes an engaging recessed portion that is recessed corresponding to the engaging protrusion.

  With this configuration, a plurality of thin layer plate pieces can be easily stacked by sequentially fitting the coupling protrusions of the other thin layer plate pieces into the coupling recesses of one thin layer plate piece. Can do. In addition, the thin layer plate piece can be easily coupled to the base by fitting the coupling protrusion of the thin layer plate piece into the coupling recess of the base, and the desired thickness can be adjusted by adjusting the number of thin layer plate pieces. A flip-up suppressing member having a size can be easily obtained. By configuring the coupling structure with the coupling protrusion and the coupling recess in this manner, the thickness dimension of the flip-up suppressing member can be easily changed while having a simple structure.

  In this case, the specific configuration of the engagement protrusion and the engagement recess is not particularly limited, but it is preferable that the engagement protrusion and the engagement recess are respectively provided at symmetrical positions. (Claim 5).

  If comprised in this way, another thin layer plate piece is rotated 180 degrees by planar view with respect to one thin layer plate piece laid flat, and a plurality of thin layer plate pieces are staggered respectively. As a result, the plurality of thin-layer plate pieces are integrally coupled with each other by fitting each projection into the mating coupling recess. Thereby, when laminating a plurality of thin layer plate pieces, it is not necessary to prepare a plurality of types of thin layer plate pieces in which the positions of the engagement protrusions and the engagement recesses are different, and a plurality of thin layer plate pieces can be formed with one type of thin layer plate piece. Thin layer plate pieces can be laminated.

  According to the sliding door flip-up restraining member according to the present invention, in the sliding door including the sliding door slide assist device having the sliding member and the receiving member, the flip-up at the start of the engagement between the sliding member and the receiving member is simple and reliable. And can be easily and reliably mounted.

  Hereinafter, the sliding door device 100 according to the present invention will be described with reference to FIG. FIG. 1 is a partially cut view showing a sliding door device 100 including a slide assist device 10, a duck (part of a structure) 70, a sill 80, and a sliding door 90 to which the flip-up suppressing member 1 according to the present invention is applied. FIG. In FIG. 1, the X direction is referred to as the left-right direction, and the Y direction is referred to as the front-rear direction. In particular, −X is referred to as the left, + X is referred to as the right, −Y is referred to as the front, Incidentally, the “side of the sliding door” in the present invention refers to the Y direction. In the example shown in FIG. 1, the sliding door 90 is opened when heading in one of the left and right directions and closed when heading in the other direction. Explain that it is released when heading to.

  First, a slide assist device 10 applied to the sliding door device 100 will be described with reference to FIG. The slide assist device 10 according to the present embodiment is provided so that the top portion is loosely fitted in the guide groove 71 of the lower surface of the duck 70 provided on the duck 70 and the lower edge extends to the sill 80 in the opening / closing direction. It is intended for a so-called standing door that can be opened and closed by moving forward and backward in the left-right direction while being fitted in the guide groove 81. The guide groove 71 of the Kamoi 70 has a groove width dimension slightly wider than a dimension obtained by adding a protruding amount from the rectangular tube body 30 of a hook member 49 described later to a width dimension of a rectangular tube body (frame body) 30 described later. Is set to

  In the present embodiment, the hook member 49 and a slide block 45 (described later) are moved forward and backward while being guided by the guide slit 33 in the rectangular tube 30 as shown in FIGS. A slide member 450 according to the invention is formed.

  On the other hand, the sliding door 90 which is one of the constituent requirements of the sliding door device 100 includes a flat plate-like door main body 91, a blindfold plate 92 provided on the upper edge of the door main body 91, and a lower edge of the door main body 91. A door wheel 93 is provided in a pair of left and right directions attached to the section.

  An unillustrated height position adjusting mechanism for adjusting the relative height position of the door wheel 93 with respect to the door body 91 is provided in the lower part of the door body 91. The inclination of the door main body 91 can be adjusted by operating this height position adjusting mechanism.

  And the slide assist apparatus 10 which is the other structural requirements of the sliding door apparatus 100 applied to such a sliding door 90 is a pair of left and right nose members 20 attached to the left-right symmetrical position of the upper edge part of the door main body 91, and A pair of left and right triggers (receiving members) 60 fixed to the front inner wall 73 (FIG. 10) of the guide groove 71 of the headquarter 70 are provided corresponding to the nose member 20. The pair of triggers 60 are for engaging with the corresponding one-side slide member 450 of the pair of nose members 20 when the sliding door 90 is opened and closed, and the front inner wall 73 of the guide groove 71 of the Kamoi 70. Are attached at symmetrical positions.

  The reason why the slide assist device 10 is provided in a pair of left and right is to allow the slide assist device 10 to enjoy the assist function both when the sliding door 90 is opened and when it is closed.

  The front-rear width dimension of each door head member 20 is set to be slightly smaller than the thickness dimension of the sliding door 90 (specifically, approximately 2/3 of the thickness dimension of the sliding door 90). A rectangular parallelepiped bifurcated piece 29 having a mounting gap 291 is fixed to the facing end face of each door nose member 20. Each mounting gap 291 is provided on the opposite surface of the forked piece 29 so as to extend in the vertical direction. The fore-and-aft width dimension of the bifurcated piece 29 is set to be slightly larger than that of the door neck member 20, so that the front edge portion of the bifurcated piece 29 protrudes forward from the door neck member 20 (FIG. 8). Yes.

  Then, the left and right end portions of the blindfold plate 92 are fitted into the mounting gaps 291 of the pair of forked pieces 29, thereby filling the gap formed between the pair of nose members 20, and this portion is thereby filled. The other side through is blindfolded.

  In such a sliding door device 100, for example, the height position of the door wheel 93 may be adjusted by the height position adjusting mechanism in order to eliminate the unoccupied closing caused by the sliding door 90 being inclined. This prevents the end of the sliding door 90 from jumping up when the sliding door 90 is opened and closed in a tilted state. However, depending on the state after adjustment, the sliding door 9 may jump up when closed. As shown in FIG. 1, the spring-up restraining member 1 is laminated on the groove bottoms (ceiling surfaces) of both ends of the guide groove 71 of the duck 70 in order to suppress the springing-up.

  FIG. 2 is a perspective view showing an embodiment of the flip-up suppressing member 1 according to the present invention, FIG. 2 (A) is an exploded perspective view, and FIG. 2 (B) is an assembled perspective view. Incidentally, FIG. 2 (B) shows a state in which the flip-up restraining member 1 fixed to the head 70 is interposed between the groove bottom of the guide groove 71 of the head 70 and the door nose member 20.

  FIG. 3 is a plan view showing an embodiment of the constituent elements of the flip-up suppressing member 1, FIG. 3A is a plan view showing the mounting plate 2, and FIG. 3B is an adjustment. FIG. 3 is a plan view showing a plate 3. 3 (B)-"1" and FIG. 3 (B)-"2" respectively show a state in which the adjustment plate 3 is phase-shifted by 180 ° on the plane. Further, FIG. 4 is a cross-sectional view taken along line IV-IV in FIG.

  In FIGS. 2 and 4, the head 70 and the door nose member 20 are simplified and shown in principle as members for sandwiching the flip-up restraining member 1, so that detailed portions differ from actual ones. ing.

  First, as shown in FIG. 2, the flip-up suppressing member 1 is provided to fill a gap between the groove bottom of the guide groove 71 of the duck 70 and the door nose member (frame body) 20. An attachment plate (base) 2 fixed to the groove bottom of the guide groove 71 of 70, one or more adjustment plates (thin layer plate pieces) 3 detachably stacked on the attachment plate 2, and adjustment While the plate 3 is mounted on the mounting plate 2, when there are a plurality of adjustment plates 3, a basic configuration having a coupling structure 4 that couples the plurality of adjustment plates 3 to each other in a stacked state is provided.

  The mounting plate 2 is set such that the length dimension corresponding to the extending direction of the guide groove 71 is shorter than 1.5 times the assist length by the slide assist device 10 and longer than the assist length. The adjustment plate 3 is set to the same length as the attachment plate 2 in this embodiment. It should be noted that the assist length means that the movement is assisted (assisted) by the biasing force of the coil spring 50 that has been extended in advance slightly before the sliding door 90 is opened or closed when the sliding door 90 is slid. This is the moving distance of the sliding door 90 from the start to the end point of assistance.

  In this way, the installation position is set by abutting one end of the flip-up restraining member 1 against the side end surface of the guide groove 71 of the duck 70 after avoiding unnecessarily lengthening the flip-up restraining member 1. Thereby, the other end part of the flip-up suppressing member 1 can be reliably positioned above one end part of the sliding door 90 when the slide assist is started. For this reason, when the flip-up restraining member 1 is mounted on the door frame (the duck 70 and the sill 80), the flip-up restraint is considered in consideration of the engagement start position of the slide block 45 and the trigger 60 described later in the slide assist device 10. There is no need to align the member 1, and by simply aligning one end of the flip-up restraining member 1 with the end wall of the guide groove 71 of the duck 70, it is possible to reliably prevent the sliding door 90 from jumping up and down. . That is, by setting the length of the flip-up suppressing member 1 as described above, the flip-up suppressing member 1 of the sliding door 90 can be easily and effectively mounted, and the workability of on-site construction is greatly improved. Can do.

  The mounting plate 2 has a rectangular shape like a strip in plan view. The mounting plate 2 is provided with a truncated conical hole (through hole) 2a that is tapered upward at a central position on the center line L extending in the longitudinal direction. Further, the mounting plate 2 has a cylindrical protrusion described later at a position separated from the center of the truncated cone hole 2a along the center line L in one direction (rightward in the example shown in FIG. 3A) by a short distance S1. An inner insertion circular hole (coupling recess) 2b into which 5 is inserted in a sliding contact state is penetrated, and at a position separated by a long distance S2 in the other direction (left side in the example shown in FIG. 3). An outer insertion circular hole (coupling recess) 2c into which the cylindrical protrusion 5 is inserted in a sliding contact state is provided.

  As shown in FIGS. 3 (B) and 4, the screw N is inserted into the truncated cone hole 2a from below and is screwed into the lower surface of the Kamoi 70 to be screwed. It is fixed to the lower surface side of Kamoi 70. The adjustment plate 3 is detachably stacked on the mounting plate 2.

  The attachment plate 2 having such a strip shape has a long side dimension of 60 mm, a short side dimension of 20 mm, and a thickness dimension of 2 mm. The short distance S1 is set to 12 mm, and the long distance S2 is set to 20 mm.

  The adjustment plate 3 has a central through hole (insertion hole) 3a corresponding to the truncated cone hole 2a, which is formed at a central position on the center line L extending in the longitudinal direction.

  Further, the adjustment plate 3 has one side of the position spaced apart from the center of the central through hole 3a by a short distance S1 in the longitudinal direction in FIG. 3 (in the example shown in FIG. 3B-1). An inner press-fitting circular hole 3b into which a later-described cylindrical projection 5 is press-fitted and fixed is provided on the right side, on the left side in the example shown in FIGS. 3 (B)-“1” in the left side, and FIG. 3 (B) — “2” in the example on the right side) an inner insertion hole into which the cylindrical protrusion 5 is fitted in a sliding state. (Coupling recess) 3c is provided.

  Further, the adjustment plate 3 has one side at a position separated from the center of the central through hole 3a on the center line L by a long distance S2 that is longer than the short distance S1 on the left and right sides (FIG. 3B- “ 1 ”on the right side, and on the left side in the example shown in FIG. 3 (B)-“ 2 ”), an outer insertion circular hole (coupling recess) into which a cylindrical projection 5 described later is fitted in a sliding contact state. 3d is penetrated, and a cylindrical projection on the other side (left side in the example shown in FIG. 3 (B)-“1”, right side in the example shown in FIG. 3 (B)-“2”) An outer press-fitting circular hole 3e through which 5 is press-fitted and fixed is provided.

  That is, in this embodiment, two sets of the press-fitting hole and the fitting hole in the adjustment plate 3 are provided at left and right symmetrical positions in the same order from the end along the center line extending in the longitudinal direction.

  A cylindrical projection (a coupling projection, indicated by a dotted line in FIGS. 3 and 4) 5 is press-fitted and fixed in the inner press-fit circular hole 3b and the outer press-fit circular hole 3e.

  The cylindrical protrusion 5 is made of a synthetic resin material that can be compressed and elastically deformed, and the length in the axial direction is set to be slightly less than twice the thickness of the adjustment plate 3. As shown in FIGS. 2 (A) and 4, the cylindrical protrusion 5 is formed concentrically from the press-fit portion 5a press-fitted into the inner press-fit circular hole 3b and the outer press-fit circular hole 3e, and the end face of the press-fit portion 5a. A head portion 5b having a larger diameter than the extended press-fitting portion 5a is provided.

  The length of the press-fit portion 5a in the axial direction is set to be substantially the same as or slightly longer than the thickness dimension of the adjustment plate 3. When the press-fitting portion 5a is set slightly longer than the thickness of the adjustment plate 3, the tip surface thereof is flush with the lower surface of the adjustment plate 3, and thereby protrudes slightly upward from the upper surface of the adjustment plate 3. It is assumed that

  Further, the axial length (thickness) of the head 5 b is set slightly smaller than the thickness dimension of the adjustment plate 3. This combined with the fact that the overall length of the cylindrical projection 5 is set to be slightly less than twice the thickness dimension of the adjustment plate 3, the head 5b is inserted into each of the insertion circular holes 2b, 2c, 3b, 3e. In such a state, it does not occur that it protrudes outside from each of the insertion circular holes 2b, 2c, 3b, 3e.

  The inner press-fit circular hole 3b and the outer press-fit circular hole 3e are set to have slightly smaller diameters than the diameter of the press-fitted portion 5a of the cylindrical protrusion 5. Therefore, the cylindrical protrusion 5 is not easily detached in a state where the press-fitting portion 5a is press-fitted into the inner press-fitting circular hole 3b and the outer press-fitting circular hole 3e.

  On the other hand, the inner insertion hole 3c and the outer insertion circular hole 3d are set to be slightly smaller in diameter than the head 5b of the cylindrical protrusion 5. Therefore, since the head 5b is slidably fitted into the inner insertion hole 3c and the outer insertion circular hole 3d in a slidable contact state, the head 5b once fitted continues this state unless an external force is applied. On the other hand, by applying an external force, the head 5b can be easily removed from the insertion holes 3c and 3d.

  In addition, the mounting plate 2 is provided with a pair of inclined edges 2d formed by chamfering each lower edge in the short direction on the lower surface side, and a short surface on the lower surface side of the adjustment plate 3. A pair of inclined edges 3f formed by chamfering is also formed on each lower edge in the hand direction. By forming the inclined edges 2d and 3f on the mounting plate 2 and the adjusting plate 3, when the plurality of stacked and connected adjusting plates 3 are separated, the inclined edges 2d and 3f are formed at the portions of the inclined edges 2d and 3f. By inserting a tool such as a screwdriver, the coupled adjustment plate 3 can be easily peeled off.

  In the present embodiment, the coupling structure 4 that removably couples the attachment plate 2 and the adjustment plate 3 and between the adjustment plates 3 to each other includes an inner insertion circular hole 2b provided in the attachment plate 2 and The press-fit portion 5a is press-fitted into the outer press-fit circular hole 2c, the inner press-fit circular hole 3b provided in the adjustment plate 3, the inner press-fit hole 3c, the outer press-fit circular hole 3d, the outer press-fit circular hole 3e, and the press-fit holes 3b and 3e. At the same time, the head portion 5b is constituted by a cylindrical protrusion 5 that is detachably fitted in the respective fitting circular holes 2b, 2c, 3c, 3d in a sliding state.

  Hereinafter, a method for attaching the spring-up restraining member 1 to the head 70 will be described based on FIGS. 5 and 6 with reference to other drawings as necessary. In the example shown in FIG. 5 and FIG. 6, the case where the flip-up suppressing member 1 is formed by one attachment plate 2 and three adjustment plates 3 is shown.

FIG. 5 (D) shows a state in which the second adjustment plate 3 is coupled to the second adjustment plate 3, and the flip-up suppressing member 1 fixed to the head 70 is a groove of the guide groove 71 of the head 70. The state interposed in the clearance gap between the bottom and the door nose member 20 is each shown.

  In order to attach the flip-up suppressing member 1 to the lower surface side of the duck 70, first, as shown in FIG. 5 (A), the mounting plate 2 is placed along the groove bottom of the guide groove 71 of the duck 70, and its longitudinal direction. One of the edges is brought into contact with the end wall of the guide groove 71. Subsequently, the mounting plate 2 is fixed to the bogie 70 by screwing the screw N passed through the truncated conical hole 2 a of the mounting plate 2 into a predetermined position of the bogie 70. With such a simple operation, the attachment plate 2 can be easily attached to the duck 70 in a positioned state, and the workability of field work can be improved.

  Next, the first adjustment plate 3 is laminated on the lower surface side of the mounting plate 2 in this state. At this time, the central through hole 3a of the adjustment plate 3 is opposed to the truncated conical hole 2a of the mounting plate 2. In this state, the cylindrical protrusions 5 of the adjustment plate 3 are made to face the inner insertion circular hole 2b and the outer insertion circular hole 2c of the mounting plate 2, respectively.

It will be in the state of wearing.

  The projecting piece 453 is set to have a vertical dimension slightly shorter than the vertical dimension of the guide slit 33, so that the slide block 45 is housed in the rectangular tube body 30. It is designed to protrude outside.

  Since the slide block 45 of the present embodiment is provided with the protruding piece 453, when the sliding door 90 is suddenly opened and closed, the protruding piece 453 engages with the engagement strip 66 of the trigger 60, thereby Since the sudden movement of the slide block 45 is suppressed by the action of the shock absorber 40, the sudden opening and closing of the sliding door 90 can be suppressed as a result.

  The Y-shaped piece 454 is for locking the left circular locking piece 55 of the coil spring 50, and the shaft portion of the circular locking piece 55 is fitted into the gap of the Y-shaped piece 454. The left end of the coil spring 50 is attached to the slide block 45. On the other hand, the circular locking piece 55 at the right end of the coil spring 50 is locked to the Y-shaped piece 232 of the second edge block 23 as described above. The left and right circular locking pieces 55 are locked to the Y-shaped pieces 454 and 232 of the slide block 45 and the second edge block 23, so that the coil spring 50 is interposed between the slide block 45 and the second edge block 23. It will be in the state.

  Further, the block base 451 is provided with a circular hole 455 for fitting the left end portion of the inner cylinder 41 at a position facing the circular hole 231 of the second edge block 23 on the right end surface thereof, and A caulking hole 456 extending in the front-rear direction so as to cross the circular hole 455 is formed. Then, in a state where the left end portion of the inner cylindrical body 41 is fitted into the circular hole 455, the pin P is fitted into the caulking hole 456 and the insertion hole 416a of the first bracket 416 to be caulked to prevent the inner cylindrical body. 41 is connected to the slide block 45.

  The hooking member 49 is attached to the slide block 45 in accordance with the opening / closing operation of the sliding door 90 (specifically, for the left slide assist device 10, when the sliding door 90 is closed, the right slide assist device is operated). 10 is for engaging the trigger 60 and preventing the relative movement of the slide block 45 relative to the duck 70 when the sliding door 90 is opened.

  The hooking member 49 has a triangular block 491 having a triangular shape tapered toward the left in a plan view and a left side in a plan view fixed to the left half of the front surface of the triangular block 491. And a tapering tongue 492. The triangular block 491 is mounted in the mounting space 46 formed between the pair of shaft support plates 452 of the slide block 45, and the vertical dimension is set slightly smaller than the vertical dimension of the mounting space 46. Yes.

  The triangular block 491 is formed with an insertion hole 491a corresponding to the caulking hole 452a extending in the vertical direction at a substantially central portion in the horizontal direction. Then, the pin P is fixed by caulking with the caulking hole 452a and the insertion hole 491a being penetrated, so that the hook member 49 is pivotally supported around the pin P and mounted on the slide block 45. Is done.

  The tongue piece 492 is set such that the vertical dimension is longer than the vertical dimension of the guide slit 33 and shorter than the vertical dimension of the square hole 34, and the horizontal dimension is set slightly shorter than the horizontal dimension of the square hole 34. Yes. And when the tongue piece 492 exists in the range of the guide slit 33, the said tongue piece 492 is the state which protruded the exterior of the square cylinder 30 from the guide slit 33, as shown in FIG.

  In this state, the right corner portion 492a of the tongue piece 492 is in contact with an engagement strip 66 (to be described later) of the trigger 60, as shown in the circle of FIG. Accordingly, if the sliding door 90 is moved to the right to open in this state, the right corner 492a of the tongue piece 492 stops against the engaging strip 66, and the slide block 45 does not move further to the right. Only the rectangular tube 30 moves to the right while the block 45 remains in that position. By this movement, the coil spring 50 expands, and the urging force is accumulated.

  When the opening operation of the sliding door 90 is continued, the tongue piece 492 finally passes through the guide slit 33 and reaches the square hole 34. The tongue 492 that has reached the square hole 34 has its inclined surface 492b engaged with the left edge of the square hole 34, and the inclined surface 492b is guided to the left edge of the square hole 34, as shown in FIG. Then, it rotates clockwise around the pin P and is immersed in the rectangular tube 30.

  The tongue piece 492 immersed in the rectangular tube 30 has the right corner portion 492a engaged with the right edge portion of the square hole 34. Therefore, the coil piece 50 is maintained in the extended state while the tongue piece 492 is kept in the extended state. The door nose member 20 can further move to the right through the engagement strip 66.

  Conversely, when the closed sliding door 90 is opened (that is, when the sliding door 90 is moved to the left), the front right edge of the triangular block 491 of the hooking member 49 with the sliding door 90 opened to some extent. The portion 491b engages with the engagement strip 66, whereby the hooking member 49 rotates counterclockwise around the pin P, and the tongue piece 492 comes out of the square hole 34 to the outside. Thus, the sliding member 90 is opened by the urging force of the coil spring 50 while the hooking member 49 moves to the right relative to the guide slit 33 by the urging force of the coil spring 50.

  By the way, in this kind of assist device, the tongue piece 492 of the hooking member 49 fails to engage with the engaging strip 66 of the trigger 60 and the coil spring 50 cannot be properly extended, or the coil spring 50 The urging force cannot be applied as the slide assist force, and the slide assist device 10 may not function normally.

  In addition, when the sliding door 90 is fully closed or opened, the tongue piece 492 that should be changed from the engagement posture to the release posture may remain in the engagement posture. In such a case, in the conventional apparatus, it was necessary to remove the sliding door 90 from the duck 70 and adjust the slide assist apparatus 10.

  Therefore, as shown in FIG. 10, the lower part of the tongue piece 492 is exposed to the outside from the duck 70 by configuring the lower part of the hooking member 49 so as to protrude downward from the guide groove 71 of the duck 70. Therefore, when the tongue piece 492 does not operate normally, it can be separated, and when a malfunction occurs, the exposed part of the tongue piece 492 can be removed by hand. It can be easily adjusted to the normal state by operating.

  The trigger 60 is for engaging with the tongue piece 492 of the hooking member 49 when the sliding door 90 is opened and closed. When the sliding door 90 is opened or closed, the trigger piece 492 and the slide block 45 are engaged with each other. It is attached to the front inner wall 73 side so as to be positioned between the protruding piece 453.

  The trigger 60 is formed by pressing a metal plate into a predetermined shape, and is formed in a single stepped shape when viewed from the left-right direction. As shown in FIG. 7, the plate-like upper bracket piece 64 is formed. And a lower bracket piece 65 positioned at a position below the upper bracket piece 64, and extending in a vertical direction constructed between a front edge portion of the upper bracket piece 64 and a rear edge portion of the lower bracket piece 65, In addition, an engagement strip 66 bulging rearward is provided. The engagement strip 66 is set to have the same vertical dimension as the vertical length of the front inner wall 73 of the guide groove 71 of the Kamoi 70.

  Further, the upper and lower bracket pieces 64 and 65 have through holes 67 at the center thereof. And while the upper bracket piece 64 is in contact with the groove bottom (top surface) of the guide groove 71 of the duck 70, the lower bracket piece 65 is in contact with the lower surface in front of the guide groove 71 of the duck 70, By inserting the wood screw M into the through holes 67 and 67 and screwing them into the headquarters 70, the trigger 60 is fixed to the headquarters 70 as shown in FIG.

  Hereinafter, the operation of the slide assist device 10 according to the present embodiment will be described with reference to FIGS. 11 and 12. FIGS. 11 and 12 are partial cross-sectional explanatory views in plan view for explaining the operation of the slide assist device 10.

When the tongue member 492 of the hooking member 49 reaches the square hole 34 and rotates clockwise around the pin P by changing the predetermined distance, the posture changes to the release posture. FIG. 11D shows a state in which the sliding door 90 is opened while the biasing force of the coil spring 50 is maintained by passing the engagement strip 66 of the trigger 60 by the tongue piece 492 set in the release posture. Continue operation And which state is shown, respectively.

  12A shows a state in which the front right edge 491b of the triangular block 491 of the hooking member 49 is engaged with the engagement strip 66 of the trigger 60 by closing the sliding door 90 once opened. FIG. 12B shows a state in which the tongue piece 492 is pulled out of the square hole 34 and changed in posture from the released posture to the engaged posture, whereby the right corner portion 492a of the tongue piece 492 is engaged with the engaging strip 66. ing. 11 and 12 are the same as those shown in FIG. 1 (-X: leftward, + X: rightward, -Y: forward, + Y: backward).

  First, as shown in FIG. 11A, in a state where the sliding door 90 is closed, the tongue piece 492 of the hooking member 49 is set to an engagement posture protruding forward from the guide slit 33, and the tongue piece 492 is provided. The right corner portion 492a is engaged with the engagement strip 66 of the trigger 60. At this time, the coil spring 50 has a minimum length that does not substantially generate an urging force.

  If the sliding door 90 is moved to the right and opened in this state, the tongue piece 492 is engaged with the engagement strip 66 of the trigger 60 and cannot move to the right. Eventually, as shown in FIG. 11B, only the rectangular tube 30 moves to the right while the slide block 45 remains in this position. Therefore, the coil spring 50 is extended by this movement of the rectangular tube 30 and the urging force is accumulated.

  When the movement of the rectangular tube 30 progresses and the tongue piece 492 is in a state corresponding to the square hole 34, the right corner portion 492a of the tongue piece 492 is relatively pressed toward the left by the engagement strip 66. In addition, since the left end portion of the inclined surface 492b is guided to the left edge portion of the square hole 34, the tongue piece 492 is rotated clockwise around the pin P, whereby FIG. As shown, the posture is changed to a release posture immersed in the rectangular tube 30 through the square hole 34.

  Next, the tongue piece 492 whose posture has been changed to the release posture is pulled rightward by the urging force of the coil spring 50, and the right corner portion 492a of the tongue piece 492 stops against the front and rear portions of the right edge of the square hole 34 ( FIG. 11D). As a result, the slide block 45 cannot move to the right relative to the rectangular tube body 30, and the coil spring 50 is in a state where the maximum urging force is held. Since the tongue piece 492 set to the release posture is released from the engagement state with the engagement strip 66, the sliding piece 90 has the tongue piece 492 that has the engagement strip 66 as shown in FIG. It can be opened while spending time.

  Then, once the sliding door 90 that has been opened is moved to the left and opened, the front right edge 491b of the triangular block 491 interferes with the engagement strip 66, as shown in FIG. As a result, the tongue piece 492 rotates counterclockwise around the pin P and changes its posture from the release posture with respect to the engagement strip 66 to the engagement posture with which the engagement strip 66 is engaged (FIG. 12 ( B)).

  The tongue piece 492 is pulled out of the square hole 34 by this posture change, and the state where the right corner portion 492a of the tongue piece 492 is locked to the right edge portion of the square hole 34 is eliminated. The triangular block 491 can enter the guide slit 33.

  Then, as shown in FIG. 12B, when the tongue piece 492 engages with the engagement strip 66 and the triangular block 491 enters the guide slit 33, the coil spring 50 is extended by elastic deformation. Since the urging force acts to move the rectangular tube 30 to the left, as a result, the sliding door 90 automatically moves to the left via the rectangular tube 30 with the assistance of the slide assist device 10 and closes. Is done.

  7 to 12, the slide assist device 10 according to the present embodiment has been described by taking as an example the one provided on the left side of the sliding door 90 that assists when the sliding door 90 is closed. It is the same as that on the left side in terms of configuration and operational effects except that it is formed symmetrically with the object and assists when the sliding door 90 is opened.

  And in the sliding door apparatus 100 which concerns on this embodiment, as shown in FIG. 1 and FIG. 10 in the right-and-left edge part of the groove bottom (ceiling surface) of the guide groove 71 of the Kamoi 70, the flip-up suppression which concerns on this embodiment is demonstrated. A member 1 is attached. The reason why the flip-up suppressing member 1 is provided at the groove bottom of the guide groove 71 of the Kamoi 70 is as follows. That is, when the sliding door 90 is opened and closed and when the biasing force of the coil spring 50 is applied, the upper portion of the sliding door 90 is pulled by the biasing force of the coil spring 50. Just before closing or immediately before full opening, the inclination is gradually bent toward the direction of travel.

  On the other hand, there is usually a gap between the upper surface of the door neck of the sliding door 90 and the groove bottom (ceiling surface) of the guide groove 71 of the Kamoi 70. Therefore, when the sliding door 90 in the forward bent state is opened and closed by the coil spring 50 and collides with the door frame, the leading edge of the sliding door largely jumps toward the gap due to the reaction, and a stable opening and closing operation is performed. The inconvenience that it becomes difficult arises. In order to eliminate such an inconvenience, the flip-up suppressing member 1 is attached to the left and right ends of the groove bottom of the guide groove 71 of the Kamoi 70.

  Hereinafter, based on FIG. 13, the operation of the flip-up suppressing member 1 provided at the groove bottoms at the left and right ends of the guide groove 71 of the duck 70 will be described with reference to other drawings as necessary. FIG. 13 is an explanatory diagram for explaining the operation in an easy-to-understand manner. FIG. 13A shows a state in which the sliding door 90 is being closed while being bent forward, and FIG. 13B shows that the sliding door 90 is completely closed. The closed state is shown in FIG. The direction display by X in FIG. 13 is the same as in FIG. 1 (−X: leftward, + X: rightward). Further, in FIG. 13, the case where the sliding door 90 is closed is shown as an example.

  First, when the opened sliding door 90 starts to be closed, the right corner 492a of the triangular block 491 of the tongue piece 492 of the hooking member 49 is the right edge of the square hole 34, as shown in FIGS. Therefore, the urging force of the coil spring 50 does not act on the sliding door 90.

  Then, as the sliding door 90 is closed to the left, the front right edge 491b (FIG. 7) of the triangular block 491 of the hooking member 49 is moved to the engagement strip 66 of the trigger 60 as shown in FIG. 13 (A). 12A and 12B, the triangular block 491 rotates around the pin P, thereby causing the right corner 492a of the tongue piece 492 to be opposed to the right edge of the square hole 34. The engagement is released. As a result, the right corner portion 492a of the tongue piece 492 engages with the engagement strip 66 of the trigger 60 integral with the duck 70, and the hooking member 49 is guided to the left by the guide slit 33. It becomes possible to move toward.

  Therefore, after that, the sliding door 90 is assisted by the closing action toward the left by the urging force of the coil spring 50, but when the protruding piece 453 collides with the engaging strip 66 before that, As shown in FIG. 13 (A), the front edge portion of the projecting piece 453 extending in the vertical direction is inclined with the upper portion facing leftward as shown in FIG. Since the upper edge collides with the engagement strip 66, a moment in the clockwise direction acts on the sliding door 90 as shown by a dotted arrow in FIG. 13A. It will go to the groove bottom of 70 guide grooves 71.

  Therefore, when the flip-up restraining member 1 is not provided at the groove bottom of the guide groove 71, when the sliding door 90 is closed by the biasing force of the coil spring 50, the upper left corner of the sliding door 90 jumps upward, Inconvenient in that it collides with the groove bottom of the guide groove 71 and generates noise, but in the present embodiment, the flip-up suppressing member 1 is provided at the groove bottom of the left end portion of the guide groove 71 of the Kamoi 70. Therefore, the jumping up of the sliding door 90 is prevented by the spring-up suppressing member 1 as shown in FIG. Thereby, the sliding door 90 can be smoothly closed in a state where the sliding door 90 is not raised.

  As described above in detail, the flip-up restraining member 1 according to the present embodiment includes the nose member 20 of the sliding door 90 interposed between the duck 70 and the sill 80 disposed opposite to the duck 70 and the duck. 70 for filling the gap between the guide groove 71 and the groove bottom of the guide groove 71, the mounting plate 2 fixed to the groove bottom of the guide groove 71, and a plurality of sheets detachably stacked on the mounting plate 2 The adjustment plate 3 is provided with a coupling structure 4 that removably couples the attachment plate 2 and the adjustment plate 3 and between the adjustment plates 3 to each other.

  According to the flip-up suppressing member 1 having such a configuration, the number of the adjustment plates 3 stacked in accordance with the gap size in order to fill the gap formed between the groove bottom of the guide groove 71 of the head 70 and the door nose member 20. Can be arbitrarily set via the coupling structure 4, and the degree of freedom in setting the thickness of the flip-up suppressing member 1 for filling the gap can be improved. In addition, it is no longer necessary to prepare in advance a plurality of types of flip-up restraining members each having a predetermined thickness according to various gap dimensions, which contributes to a reduction in the manufacturing cost of the jump-up restraining members. It is possible to improve the workability of local construction.

  And since the attachment plate 2 is formed longer than the assist length by the slide assist device 10, the attachment plate 2 is abutted against the end wall in the horizontal direction in the guide groove 71 of the Kamoi 70, thereby attaching the attachment plate 2. 2 can be reliably positioned in the guide groove 71. Therefore, when mounting the mounting plate 2 to the structure, it is not necessary to consider the relative positional relationship of each member, and the workability of the work of mounting the flip-up suppressing member 1 on the site can be greatly improved. .

  Further, the length dimension of the mounting plate 2 and the adjustment plate 3 is longer than the assist length in the slide assist device 10 and shorter than 1.5 times the assist length. The upper edge of the sliding door 90 in the traveling direction can be reliably caught by the flip-up restraining member 1 while suppressing an increase in cost due to 1 being too long.

  Further, in the coupling structure 4 according to the present embodiment, the two cylindrical protrusions 5 provided on one surface side of the adjustment plate 3 and the cylindrical protrusions 5 drilled so as to correspond to the two cylindrical protrusions 5 are slid. Two insertion holes (inner and outer insertion holes 3c, 3d) that can be fitted in a contact state, and inner and outer insertion circular holes 2b, 2c formed in the mounting plate 2 corresponding to the cylindrical protrusions 5 are provided. It is configured.

  If the coupling structure 4 is configured in this way, a plurality of adjustments can be made by sequentially fitting the cylindrical protrusions 5 of the other adjustment plate 3 into the inner and outer insertion holes 3c, 3d of one adjustment plate 3. The plates 3 can be joined in a stacked state. Further, the adjustment plate 3 can be coupled to the attachment plate 2 by fitting the cylindrical protrusion 5 of the adjustment plate 3 into the inner and outer insertion circular holes 2b and 2c of the attachment plate 2, and the number of adjustment plates 3 is adjusted. Thus, the flip-up suppressing member 1 having a desired thickness dimension can be easily obtained. Thus, by constituting the coupling structure 4 with the cylindrical protrusion 5 and the inner and outer insertion holes 3c and 3d, the thickness dimension of the flip-up suppressing member 1 can be easily changed while being a simple structure. .

  Further, the mounting plate 2 is provided with a truncated cone hole 2a for fixing the mounting plate 2 to the duck 70, and the adjustment plate 3 passes through the central portion at a position corresponding to the truncated cone hole 2a. A hole 3a is formed.

  Therefore, in a state where the adjustment plate 3 in which a predetermined number of layers are laminated on the mounting plate 2 is coupled, the screw N is inserted into the central through hole 3a of the adjustment plate 3 and the truncated conical hole 2a of the mounting plate 2 to guide the head 70. The spring-up restraining member 1 is fixed to the duck 70 by screwing and fastening to the groove bottom of the groove 71. In this way, the conical hole 2a is penetrated through the mounting plate 2 and the central through hole 3a corresponding to the frustoconical hole 2a is bored through the adjusting plate 3 to the heading 70 of the flip-up restraining member 1. Can be easily attached.

  In particular, the cylindrical protrusion 5 and the fitting circular holes 3c and 3d in the adjustment plate 3 are provided with a plurality of sets at equal pitches on the center line extending in the longitudinal direction while maintaining the same positional relationship. By alternately stacking a plurality of adjustment plates 3 so that the other adjustment plate 3 is rotated 180 ° in a plan view with respect to one adjustment plate 3 placed flat, The cylindrical protrusion 5 can be fitted into the mating insertion holes 3c and 3d, respectively. As a result, only one type of adjustment plate 3 can be used. This can contribute to a reduction in the manufacturing cost of the plate 3.

  The sliding door device 100 according to the present embodiment is provided with the slide assist device 10 that assists the opening / closing operation of the sliding door 90 that is attached to the door frame so as to be opened and closed by moving forward and backward along the duck 70 and the sill 80. In particular, the upper end on the front end side in the moving direction of the sliding door 90 jumps up to the groove bottom of the guide groove 71 of the Kamoi 70 between the groove bottom of the guide groove 71 of the Kamoi 70 and the door neck member 20. The flip-up restraining member 1 that prevents this is fixed.

  According to the sliding door device 100, when the flip-up suppressing member 1 is interposed between the groove bottom of the guide groove 71 of the duck 70 and the door neck member 20, the sliding door 90 is opened and closed and collides with the door frame. Can be suppressed. Therefore, the sliding assist device 10 is applied to the sliding door 90, and even in the case of the sliding door device 100 in which the urging force of the coil spring 50 acts when opening and closing, the sliding door 90 is likely to jump up, and thus the closing operation of the sliding door 90 is stabilized. be able to.
