  1 and 2, the sliding door structure 1 having the sliding door contact structure of the present invention has, as an example, a frame body by left and right vertical frames 2, an upper frame 3a as a duck, and a lower frame 3b as a sill. It is configured. The upper frame 3a is provided with a ditch groove (not shown) or an upper rail (not shown), and the lower frame 3b is a threshold groove (not shown) or a lower rail (not shown). ) Is provided. Two, three or more door plates 4 are mounted in the frame body thus formed. In this example, the case of an interlocking sliding door with three door plates is shown.

  A decorative face material m is attached to both sides or one side of the door plate 4 as necessary. Examples of the base plate 4 include wooden plywood, medium specific gravity fiber board, particle board, and the like, paper base materials such as paperboard and cardboard cores, and metal base materials such as steel plates. be able to. Examples of the decorative face material m include a veneer made of natural wood, a veneer, a decorative paper made of a vinyl chloride sheet, a polyolefin sheet, a thin paper, and the like.

  The mechanism in which the door plate 4 travels in the frame body includes a notch (not shown) in the upper portion of the door plate 4 in the case of the ditch groove provided in the upper frame 3a and the sill groove provided in the lower frame 3b. It is provided and a nose is formed, and the nose runs in the Kamoi trench. On the other hand, on the lower frame side, similarly, a notch (not shown) is formed in the lower part of the door plate 4 and the notch travels in the sill groove or a door wheel (see FIG. (Not shown) is attached, and the doorwheel travels in the sill groove of the lower frame 3b.

  As another mechanism, there is a structure in which the upper rail (not shown) is attached to the upper frame 3a and the lower rail (not shown) is attached to the lower frame 3b. In this structure, the suspension wheel 7 is attached to the upper part of the door plate 4, while the lower steady rest S is attached to the lower part of the door plate 4 to prevent the lower part of the door plate 4 from swinging when the door plate is running. There is a mechanism in which the suspension vehicle 7 travels in the upper rail attached to the vehicle.

  In this example shown in FIG. 1, a case of a triple sliding door having three door plates 4 is shown. However, the door contact structure of the present invention can be applied to a double sliding door, and can also be applied to a sliding door of three or more. it can. In addition, as described above, the door plate 4 traveling method may be a suspension vehicle method, a door wheel method, a door slide method, or other door plate traveling methods.

  In this example, the door plate 4 has a configuration in which the periphery of the door plate 4 is surrounded by the left and right vertical gutters 5a and the upper and lower horizontal gutters 5b, and on the front and back sides of the base material (not shown) as described above. It has a configuration finished by applying a decorative face material m. However, the door stop structure of the present invention may have a door plate configuration other than that shown in this example.

  Moreover, in this example, as the door contact structure of the three door plates 4, the linkage means R is attached at predetermined positions on the upper and lower sides of the vertical wall of each door plate 4, and when they open the door plate 4 of the sliding door When the door is closed, the door 4 is opened and closed smoothly in cooperation with each other. The linkage means R of the present invention does not necessarily have to be attached to the vertical gutter 5a of the door board 4 as shown in this example, and in a door board having a structure without the vertical gutter 5a, the attachment position may be appropriately determined. Moreover, the attachment position of the cooperation means R to the door plate 4 does not necessarily have to be two places at the upper and lower portions of each door plate 4 as shown in this example. An appropriate position in the center may be selected. Of course, there may be three places, upper, middle and lower.

  3 and 4, the linkage means R in the sliding door contact structure of the present invention includes two types of structural members, a linkage body C and an engagement body K that engages with the linkage body C. The linkage body C is composed of two linkage pieces G1 and G2, and the two linkage pieces are in a cross-sectional view taken along the line BB in FIG. It is connected in the shape of a scissors and has a shape that is bent in a substantially scissor shape in the cross-sectional shape of the line BB in FIG. 3, and a scissor-shaped step D is formed at the bent portion. Furthermore, the coupling body C of the present invention has an engagement recess U formed in the approximate center of the end of the linkage piece G1 when viewed from the front, and the upper and lower portions of the engagement recess U are formed with a projection P. In this way, the cooperative body C of the present invention has a substantially U-shape when viewed from the front.

  Further, in the linkage body C of the present invention, a first inclined surface E1 in a direction in which the bending angle of the hook-shaped bent portion is an acute angle is formed in the hook-shaped step D portion. A second surface opposite to the first inclined surface E1 is formed on the end surface opposite to the first inclined surface E1 of the both convex portions P formed in the upper and lower parts of the substantially C-shaped shape of the body C when viewed from the front. The inclined surface E2 is formed. Furthermore, flat portions H are formed at both end portions in the thickness direction of the second inclined surface E2. Moreover, the 3rd inclined surface E3 opposite to the said 1st inclined surface E1 is formed in the bottom part of the said engagement recessed part U of the cooperation body C of this invention.

  Further, in this example, two screw holes N are provided at the upper and lower portions of the hook-shaped step D for attaching the link body C of the present invention to the vertical hook 5a of the door plate 4. However, the number, position, and penetration state of the screw holes N are merely examples, and may not necessarily be the same as this example. Just decide.

  On the other hand, the engagement body K of the present invention comprises an engagement piece J and a protrusion T formed on the surface of the engagement piece J. The protruding portion T is configured to engage with the engaging recess U of the linkage body C. Furthermore, the 4th inclination which has the inclination angle and direction corresponding to the said 3rd inclined surface E3 currently formed in the bottom part of the said engagement recessed part U of the said cooperation body C in the rear-end part end surface of the said protrusion T. Surface E4 is formed. In this way, the inclined surfaces provided on the linkage body C and the engagement body K of the present invention are in contact with each other and engaged with each other so that the door plates 4 cooperate with each other to smoothly open and close the sliding door. ing.

  As an example, the linkage body C and the engagement body K of the present invention have a metal member produced by bending, punching, or casting of a thin plate such as aluminum, brass-plated steel plate, galvanized iron plate, etc. The surface is coated with a soft material. Examples of the soft material include soft vinyl resin, polyolefin resin, nylon resin, polyethylene resin, silicon resin, and urethane resin. Those coated with these are preferred.

  The reason is that when the cooperation body C and the engagement body K come into contact with each other, if the surface is covered with a soft resin, the impact and the impact sound generated along with it and the bounce of the door plate due to the impact are suppressed, This is because it is suitable for usability. In addition to the above, a soft material obtained by molding a soft vinyl resin, a polyolefin resin, a nylon resin, a polyethylene resin, a silicon resin, a urethane resin, or the like can be suitably used.

  Moreover, the dimension size as a member of the cooperation body C and the engagement body K of the present invention can be appropriately determined depending on the size of the door panel 4 of the sliding door, the shape specification of the vertical fence, and the design dimension of the clearance between the door panels 4. it can. In addition, the inclination angle of the first to fourth inclined surfaces may be appropriately designed around 45 degrees, but a preferable range is about 30 to 60 degrees for the operability of the door plate 4 when the sliding door is opened and closed. It is suitable for.

  If the inclination angle is too large, the contact surface between the linkage body C and the engagement body K slides, and the door stop function is slightly deteriorated without a good contact. Moreover, when the inclination angle is too small, the function of further ensuring the cooperative operation of the sliding doors is further reduced due to the force acting in the direction of engaging and pulling the sliding doors. Further, the size of the flat portion H provided on the second inclined surface is about 10 to 30% of the thickness dimension of the link piece G1, and the door plate is loose due to sliding when the second inclined surfaces come into contact with each other. This is a preferable range for prevention.

  5 and 6, the details of the cooperative operation between the door plates will be described in the sliding door contact structure using the cooperative body C and the engaging body K of the present invention. First, in FIG. 6, in the plan view of the sliding door structure 1, in this example, a case of a triple sliding door is shown. The farthest door panel is located on the left side, the door panel 4a, the center door panel is 4b, and the foremost door panel is located on the right side, the door panel 4c.

  The linkage body C1 is screwed to the upper and lower portions of the right vertical gutter 5a toward the front surface of the innermost door plate 4a. At this time, the linkage piece G1 of the linkage body C1 is attached to the front, and the second inclined surface E2 is attached to the outside of the door plate.

  Next, the cooperation body C is attached to the four places of the upper part and the lower part of the left and right vertical gutters 5a on the back side surface of the central door plate 4b. On the left vertical shaft 5a, the linkage piece G1 is attached to the back side and the second inclined surface E2 is attached to the outside of the door plate 4b. The cooperative body in this case is C2. Further, the right vertical gutter 5a is attached with the linkage piece G1 on the back side and the second inclined surface E2 inside the door plate 4b. The cooperative body in this case is C3.

  Next, the cooperation body C4 is attached to two places of the upper part and the lower part of the right vertical gutter 5a toward the near side surface of the central door plate 4b. At this time, in the same manner as in the case of the door plate 4a, it is attached with the link piece G1 of the link body C4 facing forward and the second inclined surface E2 outside the door plate 4b.

  Next, the cooperation body C5 is attached to two places of the upper part and lower part of the left vertical gutter 5a toward the back | inner side surface of the frontmost door board 4c. At this time, as in the case of the vertical gutter 5a on the left side of the back surface of the door plate 4b, the link piece G1 of the link body C5 is set to the back side and the second inclined surface E2 is set to the outside of the door plate 4c. And attach.

  Finally, the engagement body K is attached to the upper and lower portions of the right vertical saddle toward the back surface of the door plate 4c. In this case, the protrusion T is attached to the back side, and the fourth inclined surface E4 formed at the rear end of the protrusion is attached in a direction facing the inside of the door plate 4c.

  In (a), (b), and (c) of FIG. 5, the contact state between each linkage body C1 to C5 and the engagement body K in the opening / closing operation of each door plate 4a, 4b, and 4c will be described. In (A), when the door plate is closed, the first inclined surfaces E1 and E1 of the two linkage bodies C come into contact with each other, and the door plates move together to move in the direction of closing the door plate while interlocking with each other. At this time, the operation of the inclined surface further ensures the cooperation between the door plates.

  In addition, (b) when the door panel is opened, the second inclined surfaces E2 and E2 of the two linkage bodies C come into contact with each other so that the door panels cooperate with each other and move in the direction of opening the door panel while interlocking with each other. is there. At this time, the operation of the inclined surface further ensures the cooperation between the door plates. Then, at the end of the opening of the three sliding doors in the right-aligned state, the second inclined surfaces E2 are brought into contact with each other, so that the left vertical puller (not shown) of the innermost door plate 4a is drawn. It is configured to prevent the danger of injury by pinching fingers.

  Further, at this time (b), as can be seen from the enlarged view of the main part of the contact portion between the second inclined surfaces E2, flat portions H are provided at both ends of the inclined surface. Due to the function of the flat portion H, when the sliding door structure is not sufficiently built-in accurately, when the second inclined surfaces E2 of the door plates come into contact with each other, they do not slide and do not perform the function of the door stop. It effectively prevents fear.

  Further, in (c), when the door plate is opened, the third inclined surface E3 of the linkage body C and the fourth inclined surface E4 of the engagement body K come into contact with each other, and the door plates cooperate with each other while being hooked and interlocked. It moves in the direction of opening the doorboard. At this time, the operation of the inclined surface further ensures the cooperation between the door plates.

  FIG. 6 is a plan view in the case of a triple sliding door, and shows the opening / closing operation of each door plate 4a, 4b, 4c. (A) shows a case where all three sliding doors are closed, (B) shows a case where all three sliding doors are opened, and shows a case where all the sliding doors are moved to the right side. (C) shows a case where all three sliding doors are opened, and shows a case where all the sliding doors are moved to the left side.

  When the doors 4a, 4b, 4c are closed (A) to open (B), the linkage means R operates as follows. That is, when the door 4a is slid in the right direction by placing a hand on a puller (not shown) on the left vertical shaft 5a toward the left door plate 4a, the linkage on the right vertical shaft 5a is directed.

That is, when the door plate 4c is slid in the right direction by placing a hand on the puller (not shown) of the right vertical shaft 5a of the frontmost door plate 4c, the left vertical shaft 5a is located on the far side of the door plate 4c. The first inclined surface E1 of the cooperative body C5 and the first inclined surface E1 of the cooperative body C4 of the vertical shaft 5a on the right side of the front side of the central door plate 4b are in contact with each other, and the door plate 4c hooks the door plate 4b to the right. As shown in (a), the three door plates 4a, 4b, and 4c are fully closed.

  Next, in the case of transition from the fully opened state of the three door plates 4a, 4b, 4c as shown in (b) to the fully opened state of the left aligned state as shown in (c), Cooperation means R works. That is, when a hand is put on a pull (not shown) of the left vertical gutter 5a of the front panel 4c and is slid leftward, the engagement body K in the right vertical gutter 5a on the back side of the door board 4c. The fourth inclined surface E4 in the middle and the third inclined surface E3 of the linkage C4 on the right vertical shaft 5a on the near side of the central door plate 4b are in contact with and hooked, and the back of the central door plate 4b The second inclined surface E2 of the cooperative body C3 on the right side vertical shaft 5a and the second inclined surface E2 of the cooperative body C1 on the right vertical shaft 5a on the front side of the innermost door plate 4a abut. The three door plates are interlocked and moved to the left while being hooked, and the fully opened state in the left-justified state as shown in (c) is obtained.

  Next, in the case of transition from the fully open state in the left-justified state of the three door plates 4a, 4b, and 4c as shown in (c) to the fully-opened state in the right-justified state as shown in (b), The linkage means R works as follows. That is, a hand is placed on a puller (not shown) of the frontmost door plate 4c to move the door plate 4c to the right by a slight distance, and then a puller of the vertical rod 5a on the left side of the central door plate 4b (see FIG. (Not shown) is visible from the outside, and a hand is placed on the handle to move the door plate 4b to the right by a small distance. In this way, the left vertical gutter 5a can be seen from the outside toward the innermost door plate 4a.

  Therefore, when a hand is placed on a puller (not shown) on the left vertical shaft 5a toward the innermost door plate 4a and is slid rightward, the right vertical shaft 5a on the front side of the door plate 4a is present. While contacting and hooking the second inclined surface E2 in the cooperative body C1 and the second inclined surface E2 in the cooperative body C3 in the right vertical shaft 5a on the back side of the central door plate 4b, and the central door plate The 4th inclination in the engagement body K in the 3rd inclined surface E3 in the cooperation body C4 in the right vertical shaft 5a of the near side 4b of 4b, and the right vertical shaft 5a in the back side of the foremost door board 4c. While the surface E4 is in contact with and hooked, the three door plates move in the right direction in conjunction with each other and are fully opened in a right-justified state as shown in (b).
