Description

  The present invention relates to a structure for connecting and supporting an opening / closing body to a guide means for guiding the movement of the opening / closing body and a method for connecting and supporting the opening / closing body. It can be used for a movable partition panel or the like that is movable along the rail.

  For example, a suspended sliding door is known as an opening / closing member for freely opening and closing an entrance / exit opening between a corridor in a building and a room. This sliding door is connected and supported via a connecting means from a slide rail arranged at the upper part of the entrance / exit opening, and is guided by the slide rail to be movable. The coupling means is inserted into a first coupling member coupled to the slide rail, a second coupling member coupled to the upper end of the sliding door, and a hole formed in the first and second coupling members. It consists of connected pins. The sliding door is swingable around a pin, and this swinging prevents the rotation moment from acting on the slide rail having a small resistance to the rotation moment caused by the external force.

  Conventionally, the operation of connecting the sliding door to the slide rail through the connecting means at the construction site of the upper suspension type sliding door includes the hole of the first connecting member coupled to the slide rail and the second coupling coupled to the sliding door. This is done by aligning the holes of the member and inserting the pins into these holes.

  According to this conventional working method, in order to connect and support the upper suspension type sliding door to the slide rail, the hole of the first connecting member and the hole of the second connecting member are matched, and a pin is inserted into these holes. Since the hole for inserting the pin is small, and this operation must be performed at a high place at the upper end of the upper suspension type sliding door, the workability is poor, and it takes time and effort.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a connection support structure and a connection support method for an opening / closing body that can easily perform an operation of connecting and supporting an opening / closing body such as a suspension type sliding door to a guide means such as a slide rail via a connection means. There is to offer.

  The connection support structure for an opening / closing body according to the present invention includes an opening / closing body having guide means, an opening / closing body whose movement is guided by the guide means, and a connection means for connecting and supporting the opening / closing body to the guide means. In the connection support structure, the connection means includes a connection portion provided in one of the guide means and the opening / closing body, a locking portion provided in the other, and a locking portion provided in the connection portion. It is characterized by including the to-be-latched part by which the part was latched.

  Also, the connection support method of the opening / closing body according to the present invention is the connection support method of the opening / closing body in which the opening / closing body guided to move by the guide means is connected to and supported by the guide means. A locking portion is provided at one of the connecting portions and a locking portion is provided at the other, and then the opening and closing of the guide means is achieved by locking the locking portion to the locked portion. The body is connected and supported.

  That is, according to the present invention, a connecting portion is provided on one of the guide means and the opening / closing body guided to move by the guide means, and a locking portion is provided on the other, and the engaged portion provided in advance on the connecting portion. The locking part is locked to the locking part.

  In the present invention, since the locked portion is provided in the connecting portion before the locking portion is locked to the locked portion, the operation of connecting and supporting the opening / closing body to the guide means is performed on the locked portion. It is only necessary to perform the operation of locking the locking portion, and the work can be simplified.

  Further, when the operation of locking the locking portion to the locked portion is performed, the locked portion is provided in the connecting portion, so that the locked portion is integrated with the connecting portion and locked. It becomes possible to perform the locking operation of the portion, and the handling and management of the locked portion can be facilitated.

  The manner in which the locked portion is provided in the connecting portion is arbitrary. For example, the locked portion may be provided in the cantilever state in the connecting portion, or may be provided in the both-held state.

  An example of the case where the locked portion is provided on the connecting portion in a both-sided state is that the connecting portion has a bifurcated portion that holds the locked portion. The locking portion is locked to the intermediate portion of the locked portion that is held and exposed by the bifurcated portion of the connecting portion.

  According to this, since the locked portion is supported at both ends by the connecting portion, the strength of the locked portion with respect to the connecting portion can be increased, and the locked portion exposed between the forked portions of the connecting portion can be increased. Since the operation of locking the locking portion only needs to be performed, this locking operation can be easily performed.

  The shape of the locking portion is arbitrary as long as it can be locked to the locked portion. For example, the portion that locks the locked portion can be inserted into the locked portion like a hook shape. It may be a loop shape that is closed except for the portion, or may be a fishhook shape that opens downward. Moreover, the shape of the to-be-latched part is also arbitrary, for example, a linear pin shape (including bolts), a complete ring shape such as horizontally long or vertically long, or an incomplete ring shape may be used.

  Further, the structure for connecting and supporting the opening / closing body to the guide means may include a drop-off preventing portion for preventing the locking portion from dropping from the locked portion. If it does in this way, it will become possible to prevent that the latching | locking part latched by the to-be-latched part falls from the to-be-latched part.

  The drop prevention portion may be provided on at least one of the coupling portion and the locking portion before the locking portion is locked to the locked portion, and the locking portion is engaged with the locked portion. It is good also as what is provided in at least one of the said connection part and the said latching | locking part after stopping.

  However, in the latter case, there is no drop-off prevention part when the locking part is locked to the locked part, so the work of locking the locking part to the locked part is not performed. You can easily do this without getting in the way.

  Further, it is preferable that the drop-off prevention portion intervenes at a position that prevents the locking portion from being released from the locked portion between the member on the guide means side and the member on the opening / closing body side.

  In this way, even if the locking portion is about to come out of the locked portion, in other words, even if the locking portion is locked to the locked portion, the lock-off preventing portion does not release the lock. Thus, the locking of the locking portion to the locked portion can be continued.

  The member on the side of the guide means and the member on the side of the opening / closing body here belong to either the guide means or the opening / closing body with the locking portion and the locked portion of the connecting means as a boundary. For example, when the connecting part is provided in the guide means and the locking part is provided in the opening / closing body, the member on the guide means side means the guide means Self, a connecting part, a locked part attached to the connecting part, a member to which a guide means is attached, etc., and the member on the side of the opening / closing body refers to the opening / closing body itself, a locking part, etc. That is.

  In the above, the connection part, the locking part, and the locked part may be a single member (part) or a part of the member (part).

  Further, the present invention described above can be applied to connect and support an arbitrary opening / closing body to an arbitrary guide means. One example is a case where the upper suspension type sliding door is connected and supported by the slide rail, and another example is a case where the movable partition panel is connected and supported by a rail provided on the ceiling or the like. In addition, the present invention can connect and support an upper suspension type sliding door to a roller that is movably engaged with a guide rail, or a door that rotates along a rail provided on a ceiling or the like. It can also be applied to Furthermore, the present invention can also be applied to a case where an opening / closing body such as a balance door, a folding door, an overhead door, and a translucent strip-like sheet is connected to and supported by the guide means.

  The guide means such as a rail may extend in the horizontal direction, may extend in the vertical direction, or may extend in a direction inclined with respect to these directions.

  Furthermore, the present invention can also be applied to an opening / closing body in which two opposite sides are connected and supported by two guide means via connecting means, and the number of guide means is not limited to one.

  When the present invention is applied to connect and support an upper suspension sliding door to a slide rail, the guide means becomes a slide rail extending in the horizontal direction, and the opening / closing body is suspended from the slide rail via the connection means. It will be a suspended sliding door. Further, the locked portion of the connecting means is horizontal, and the upper suspension type sliding door is swingable around the locked portion.

  According to this, the upper suspension type sliding door swings around the locked portion, so that it becomes possible to prevent the rotational moment due to the external force from acting on the slide rail, and the slide rail is protected from this rotational moment. It will be.

  According to the present invention, it is possible to easily perform the operation of connecting and supporting the opening / closing body to the guide means via the connecting means.

FIG. 9 is a view similar to FIG. 5 showing a case where a drop-off preventing member is added in the embodiment of FIGS. 7 and 8. FIG. 10 is a view similar to FIG. 6 in the embodiment of FIGS.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an entire slide rail type upper suspension type sliding door device to which the connection support structure of the first embodiment is applied, and FIG. 2 is a partially broken view showing a drive mechanism of the upper suspension type sliding door. FIG. 3 is a sectional view taken along line III-III in FIG.

  As shown in FIG. 1, the upper sliding door 1 opens and closes an opening 6 in a building surrounded by a vertical frame 2, an upper frame 3, a vertical frame 4, and a lower frame 5. When opened, the sliding door 1 is housed inside the door pocket 7. The opening 6 is, for example, for an entrance provided between a hallway and a room in a building. An upper suspension drive mechanism 8 shown in FIG. 2 is arranged inside the upper frame 3 that can be opened and closed by a detachable cover 3A. The drive mechanism 8 is arranged on the inner surface of the upper frame 3 as shown in FIG. The following devices, means, and members are attached to an attachment member 10 that is fixed to the plurality of reinforcing members 9 and extends in the sliding door moving direction.

  This will be described in detail with reference to FIG. 2. The drive mechanism 8 includes a spiral spring device 11 attached to the sliding door closing side end of the attachment member 10, and a slide rail 12 having a length over almost the entire length of the attachment member 10. And an air damper 13 attached to the attachment member 10 with the piston rod 13A facing the sliding door opening side at the upper part of the slide rail 12.

  As shown in FIG. 3, the slide rail 12 is fixed to the mounting member 10, and the stationary member 12 </ b> A that is long in the moving direction of the sliding door 1 faces the stationary member 12 </ b> A in the horizontal direction. The movable member 12B, which is short in the moving direction, and a large number of balls 12C arranged between the immobile member 12A and the movable member 12B are rotatably held, and the length of the sliding door 1 in the moving direction is increased. The movable member 12B is movable in the longitudinal direction of the slide rail 12 with respect to the stationary member 12A by a ball 12C. The movable member 12B has substantially the same length as the width of the sliding door 1, and the sliding door 1 is connected to and supported by the movable member 12B via connecting means 14 and 15 shown in FIG. It is an upper suspension type sliding door suspended by the connecting means 14 and 15.

  One end of the wire 16 extending from the spiral spring device 11 is connected to one of the connecting means 14, and therefore when the sliding door 1 is opened and moved to the door pocket 7 side by the gripping portion 1A shown in FIG. The sliding door 1 opens and moves while being guided by the slide rail 12 and the guide roller 17 of the lower frame 5 in FIG. 1, and the spiral spring of the spiral spring device 11 is accumulated by the wire 16 that is fed out. For this reason, when the hand is released from the gripping portion 1A, the sliding door 1 automatically moves to the closing side via the wire 16 and self-closes by the spring force of the accumulated spiral spring.

  Further, a magnet 18 is provided at the tip of the piston rod 13A of the air damper 13 shown in FIG. 2, and the side of the connecting means 15 facing the piston rod 13A of the connecting means 14 and 15 in the sliding door opening / closing direction is also provided. A magnet 19 is provided. When the sliding door 1 is opened and moved, the piston rod 13A of the air damper 13 extends through the magnets 18 and 19 adsorbed to each other, and when the sliding door 1 moves a certain distance, the magnets 18 and 19 are separated. . When the sliding door 1 is closed and moved, the piston rod 13A starts to contract after the magnets 18 and 19 are attracted again, and thereafter, the air sucked into the air damper 13 during the extension behavior of the piston rod 13A is retained at the orifice. Since it is discharged while being squeezed, the self-closing of the sliding door 1 is performed at a reduced speed.

  The connecting means 14 and 15 shown in FIG. 2 form the connecting portion in this embodiment, and the connecting member 21 coupled to the movable member 12B of the slide rail 12 by the fastening tool 20 and the stopper. The hook member 23 is coupled to the upper end of the sliding door 1 by the attachment 22 and the pin 24 is attached horizontally to the connecting member 21. The hook member 23 is locked to the pin 24. Therefore, in this embodiment, the hook member 23 forms a locking portion, and the pin 24 forms a locked portion.

  In both of the connecting means 14 and 15, the connecting means 15 is larger than the connecting means 14 by the provision of the mounting portion of the magnet 19, and the other connecting members in these connecting means 14 and 15 are excluded except for this. 21, each hook member 23, and each pin 24 have the same shape, function, etc., and therefore will be described with the same reference numerals.

  The lower part of the connecting member 21 of the connecting means 14, 15 is a bifurcated portion in which curled portions 21A are formed at both ends in the sliding door moving direction, and both ends of the pin 24 are inserted and fixed to these curled portions 21A. . For this reason, the intermediate portion 24 </ b> A between the forked portions of the pin 24 is exposed from the connecting member 21. Further, as shown in FIG. 3, the upper part 23A of the hook member 23 has a fishing hook shape opened downward, and the width of the upper part 23A in the sliding door moving direction is as shown in FIG. The opening width between the two forked portions, that is, the interval between the two curled portions 21A is shorter.

  The upper portion 23 </ b> A of the hook member 23 is inserted into the opening between the two forked portions of the connecting member 21 and is locked to the pin 24.

  For this reason, the operation of connecting and supporting the sliding door 1 to the slide rail 12 via the connecting means 14 and 15 at the construction site of the upper suspension sliding door apparatus is performed as follows. First, the connecting member 21 is coupled to the movable member 12B of the slide rail 12 by the fastening tool 20 at the factory or construction site, and the hook member 23 is joined to the sliding door 1 and the fastening tool 22 is joined to the cover 3A at the construction site. The sliding door 1 is lifted toward the slide rail 12 assembled to the inside of the upper frame 3 before the attachment or the like (see FIG. 4), and the upper portion 23A of the hook member 23 is inserted into the opening between the two forks of the connecting member 21. After that, the hook member 23 is locked to the intermediate portion 24A of the pin 24 from above by lowering the sliding door 1. Thereby, the operation | work which connects the sliding door 1 which is an opening / closing body to the slide rail 12 which is a guide member via the connection means 14 and 15 is complete | finished.

  For this reason, according to the present embodiment, as an operation for connecting and supporting the sliding door 1 to the slide rail 12 via the connecting means, unlike the prior art, each of the sliding rails and the sliding doors combined to form the connecting means. It is not necessary to perform the cumbersome work of connecting the connecting members by aligning the positions of the holes of the connecting members and inserting pins into these holes. This work can be easily completed in a short time, and the workability is improved. .

  Further, since the pin 24 is supported at both ends by the bifurcated portion provided in the connecting member 21, the mounting strength of the pin 24 to the connecting member 21 is large, and the hook member is attached to the pin 24 having the large mounting strength. Since 23 is locked, the connection support strength of the sliding door 1 to the slide rail 12 is also increased.

  Moreover, since the part of the pin 24 which latches the hook member 23 is the intermediate part 24A exposed between the forked parts of the connecting member 21, this latching can be performed easily.

  Further, since the pin 24 is attached to the connecting member 21 before the hook member 23 is locked, the pin 24 is not separated from the connecting member 21, so that the pin 24 is integrated with the connecting member 21. In this state, the hook member 23 can be locked, and the handling and management of the pins 24 can be facilitated.

  Further, since the sliding door 1 is swingable around the pin 24, even if an external force is applied to the sliding door 1, this external force is absorbed by the swinging of the sliding door 1 around the pin 24 and becomes a rotational moment due to the external force. On the other hand, it is possible to prevent the rotational moment from acting on the slide rail 12 having a small resistance.

  5 and 6 show a case where the drop-off preventing member 30 for preventing the hook member 23 from dropping from the pin 24 is added in the above embodiment. The drop-off prevention member 30 that forms the drop-off prevention portion has an inverted L shape including a vertical portion 30A and a horizontal portion 30B extending in the horizontal direction from the upper end of the vertical portion 30A. After the hook member 23 is locked to the pin 24, the horizontal portion 30B is inserted vertically between the mounting member 10 to which the slide rail 12 is attached and the upper portion 23A of the hook member 23 as shown in FIG. The part 30 </ b> A is fixed to the hook member 23 with the fixing tool 31.

  When the horizontal portion 30B is inserted between the mounting member 10 and the upper portion 23A of the hook member 23, the horizontal portion 30B is brought into contact with the lower surface of the mounting member 10 when the sliding door 1 is lifted to raise the hook member 23. The distance is H1. On the other hand, the vertical depth at which the hook member 23 is engaged with the pin 24 is H2. By making H1 smaller than H2, in other words, by fixing the drop-off prevention member 30 having a thickness of the horizontal portion 30B that can make H1 smaller than H2, to the hook member 23, the hook member The horizontal portion 30 </ b> B hits the lower surface of the mounting member 10 before 23 is removed from the pin 24.

  Therefore, the horizontal portion 30B of the drop-off prevention member 30 inserted between the mounting member 10 that is the member on the slide rail 12 side and the hook member 23 that is the member on the sliding door 1 side is the hook member from the pin 24. The hook member 23 is prevented from falling off the pin 24 even when an unexpected external force is applied to raise the sliding door 1.

  7 and 8 show another embodiment in which the connecting means is different from the embodiment of FIGS. The connecting means of this embodiment includes a hook member 43 that is a locking member connected to the movable member of the slide rail 12, a connecting member 41 that is connected to the upper end of the sliding door 1, and a horizontal attachment to the connecting member 41. And a pin 44. Curled portions 41A are formed at both ends of the connecting member 41 in the sliding door moving direction, and therefore the lower portion of the connecting member 41 is a bifurcated portion. Both ends of the pin 44 that is a member to be locked are inserted into these curled portions 41A, and the intermediate portion 44A is exposed from between the two forks.

  The operation of connecting and supporting the sliding door 1 to the slide rail 12 through the connecting means is performed by lifting the sliding door 1 and locking the pin 44 to the lower portion 43 </ b> A opened obliquely upward of the hook member 43. Therefore, in this embodiment as well, the operation of connecting and supporting the sliding door 1 to the slide rail 12 can be easily performed, as in the embodiment of FIGS. The same effect as the above-mentioned effect about a form can be achieved.

  FIGS. 9 and 10 show a case where a drop-off prevention member 50 for preventing the pin 44 from dropping from the hook member 43 is added in the embodiment of FIGS. 7 and 8. The dropout prevention member 50 has a square shape including a vertical portion 50A and an inclined portion 50B extending obliquely downward from the lower end of the vertical portion 50A. After the sliding door 1 is lifted and the pin 44 is locked to the hook member 43, the vertical portion 50A of the drop-off preventing member 50 is fastened to the hook member 43 with a fastening tool 51 as shown in FIG. The lower end of 50B is made to face the upper surface of the pin 44 obliquely from above, or the lower end of the inclined portion 50B is brought into contact with the upper surface of the pin 44 from obliquely above, so that the opening of the lower portion 43A of the hook member 43 is at the lower end of the inclined portion 50B. By closing, the size of the opening is made smaller than the diameter of the pin 44.

  As a result, the drop-off prevention member 50 releases the locking of the hook member 43 to the pin 44 between the hook member 43 that is a member on the slide rail 12 side and the pin 44 that is a member on the sliding door 1 side. The pin 44 can be prevented from falling off from the hook member 43 even if an unexpected external force is applied to raise the sliding door 1.

  The present invention can be used for, for example, an upward-sliding sliding door supported by being suspended from a slide rail, a movable partition panel that is movable along a ceiling rail, and the like.
