Summary of the Invention

Problems to be Solved by the Invention

[0004] In such a closer, the closer must be attached to an optimal position for completely closing the door body with respect to the guide rail that supports the door body. However, regarding at which position on the guide rail the closer should be attached so that the door body can be pulled to a completely closed position, it varies depending on the width of each frame body. For this reason, conventionally, complicated operations such as individually and specifically calculating the position of the closer to be attached to the guide rail and creating design drawings have been required.

[0005] The present invention has been made in view of the above points, and an object thereof is to provide a jig that can easily determine an optimal attachment position of a closer with respect to a guide rail regardless of the width of a frame body.

Means for Solving the Problem

[0006] In order to solve such a problem, in the present invention, there is provided a jig for attaching a closer to an optimal position with respect to a guide rail along which a door body is fully closed or fully opened along the guide rail attached to a frame body. The jig includes a main body portion detachably attached to the guide rail, a protruding portion attached to an upper end portion of the door body and having an end surface that runs along the guide rail and contacts a moving roller that is drawn into the closer, and a through hole provided along the vertical direction at a position of the main body portion that is separated from the end surface of the protruding portion by a predetermined distance.

[0007] In the present invention, when the door body is fully closed in a state where the end surface of the protruding portion contacts the moving roller and is attached to the guide rail, the main body portion preferably moves along the guide rail together with the moving roller and stops, and the position of the guide rail facing the through hole is set as the position of the through hole of the closer provided for attaching the closer to the guide rail.

[0008] In the present invention, it is preferable that a protruding portion for detachably attaching to the guide rail is provided on a side surface of the main body portion.

[0009] In the present invention, it is preferable that the main body portion has a width that can be inserted between a pair of flange wall portions on which the tire of the moving roller rolls.

Advantages of the Invention

[0010] According to the above configuration, it is possible to realize a jig that can easily determine the optimal attachment position of the closer with respect to the guide rail regardless of the lateral width of the frame body.

[0012] 1. Outline of Embodiment First, an outline of a typical embodiment of the invention disclosed in the present application will be described. In the following description, as an example, reference numerals on the drawings corresponding to the components of the invention are described with parentheses attached.

[0013] 〔1〕In a typical embodiment of the present invention, a jig (300) for attaching a closer (230) to an optimal position with respect to a guide rail (170) in order to fully close or fully open a door body (130, 150) along the guide rail (170) attached to a frame body (110). The jig (300) includes a main body portion (301) detachably attached to the guide rail (170), a protruding portion (303) attached to the upper end portion of the door body (130, 150) and having an end face (303a) that runs along the guide rail (170) and contacts a moving roller (190) drawn into the closer (230), and a through hole (305) provided along the vertical direction at a position of the main body portion (301) separated from the end face (303a) of the protruding portion (303) by a predetermined distance. has.

[0014] 〔2〕In the present invention, when the door body (130, 150) is fully closed with the end face (303a) of the protruding portion (303) in contact with the moving roller (190) and attached to the guide rail (170), the main body portion (301) moves along the guide rail (170) together with the moving roller (190) and stops. The position of the guide rail (170) facing the through hole (305) is set as the position of the through hole (231a) of the closer (230) provided for attaching the closer (230) to the guide rail (170).

[0015] 〔3〕In the present invention, a protruding portion (302) for detachably attaching to the guide rail (170) is provided on the side surface of the main body portion (301).

[0016] 〔4〕In the present invention, the main body portion (301) has a width that can be inserted between a pair of flange walls (173) on which the tire (193) of the moving roller (190) rolls.

[0017] 2. Specific Example of the First Embodiment Hereinafter, with reference to FIGS. 1 to 7, the jig according to the embodiment of the present invention and the configuration of the folding door device using the jig will be described in detail. Further, with reference to FIGS. 8 to 12, the flow until the attachment position of the closer is determined using the jig according to the embodiment of the present invention and the closer is attached will be described in detail.

[0018] In the description of FIGS. 1 to 12 below, when viewing the folding door device 100 from the front, the left side is the door-closed side (in the direction of arrow a), the right side is the door-open side (in the direction of arrow b), the back side with respect to the paper surface is the indoor side (in the direction of arrow c), the front side is the outdoor side (in the direction of arrow d), the upper side when viewing the folding door device 100 from the front is the ceiling side (in the direction of arrow e), and the lower side is the floor surface side (in the direction of arrow f). Therefore, the opening / closing direction, the horizontal direction or the left-right direction (in the direction of arrow ab), the depth direction (in the direction of arrow cd), and the up-down direction (in the direction of arrow ef) are defined, and the left end portion of the first door body 130 is called the door tip side, and the right end portion of the second door body 150 is called the hanging end side of the door body.

[0019] <Folding Door Device> As shown in FIGS. 1 and 2, in the embodiment of the present invention, the folding door device 100 to which the jig 300 (FIG. 6) is applied has a frame body 110, a first door body 130, a second door body 150, a guide rail 170, a moving roller 190, a fixed roller 210, and a closer 230. Note that in FIG. 1, the jig 300 is not shown, and the jig 300 will be described later.

[0020] <Frame Body> The frame body 110 forms a rectangular opening with an upper frame 111, a left frame 113, a right frame 115, and a lower frame 117. The guide rail 170 is fixed to the upper frame 111. The distance between the left frame 113 and the right frame 115 is slightly larger than the length when the first door body 130 and the second door body 150 are arranged linearly.

[0021] As shown in FIG. 3, the upper frame 111 has a substantially inverted U-shaped cross section and has a rectangular concave space 111s in the central portion of the cross section. This concave space 111s is formed by two corresponding inner surfaces 111a, 111b and a ceiling surface 111u connecting between the two inner surfaces 111a, 111b. A guide rail 170 is fixed to the ceiling surface 111u of the upper frame 111.

[0022] <The first door body and the second door body> As shown in FIG. 2, the first door body 130 is arranged on the left side when the folding door device 100 is viewed from the front, and is composed of a plate-like member having a larger area than the second door body 150. The second door body 150 is arranged on the right side when the folding door device 100 is viewed from the front, and is composed of a plate-like member having a smaller area than the first door body 130.

[0023] A handle 130a is attached to the left end of the surface of the first door body 130 on the outdoor side (in the direction of arrow d). In the first door body 130, a handle 130b is also attached at the position of the back surface on the indoor side (in the direction of arrow c) in the same manner as the handle 130a on the surface.

[0024] The width of the first door body 130 is twice the length of the second door body 150 and has a size ratio of 2:1. However, it is not limited to this. For example, as long as the second door body 150 does not exceed the width of the first door body 130, other size ratios may be used.

[0025] The first door body 130 and the second door body 150 are foldably connected to each other by an upper hinge 141 at the upper right end of the first door body 130 and the upper left end of the second door body 150. Similarly, the first door body 130 and the second door body 150 are foldably connected to each other by a lower hinge 143 at the lower right end of the first door body 130 and the lower left end of the second door body 150.

[0026] Therefore, for example, when the user holds the handle 130a of the first door body 130 and pushes the first door body 130 toward the back side (in the direction of arrow c), the upper hinge 141 and the lower hinge 143 are moved toward the front side (in the direction of arrow d), and the first door body 130 and the second door body 150 are folded to an open state (see Fig. 8(B)). Incidentally, when the user pushes the handle 130a of the first door body 130 toward the front side (in the direction of arrow d), the upper hinge 141 and the lower hinge 143 are moved toward the back side (in the direction of arrow c), and the first door body 130 and the second door body 150 are folded to an open state. That is, in the folding door device 100, the first door body 130 and the second door body 150 can be folded in both directions to form an open state.

[0027] Further, in the open state of the first door body 130 and the second door body 150, when the user pulls the first door body 130 toward the front side (in the direction of arrow d), the upper hinge 141 and the lower hinge 143 return to their original positions, and the first door body 130 and the second door body 150 are deployed to a closed state (see Fig. 9(B)).

[0028] <Guide rail> As shown in Fig. 3, the guide rail 170 is substantially inverted U-shaped and integrally fixed to the ceiling 111u of the upper frame 111 in the frame body 110, and has a width slightly smaller than the distance between the left frame 113 and the right frame 115.

[0029] The guide rail 170 has a top wall portion 171, a pair of side wall portions 172, and a pair of flange wall portions 173. The top wall portion 171 of the guide rail 170 is integrally fixed to the ceiling surface 111u of the upper frame 111 by a fixture or adhesion or the like.

[0030] The top wall portion 171 of the guide rail 170 is a plate-like portion extending along the longitudinal direction of the upper frame 111 between the left frame 113 and the right frame 115 of the frame body 110. The top wall portion 171 has two protruding wall portions 171a extending parallel to each other by a predetermined length downward (in the direction of arrow f) at the center.

[0031] The two protruding wall portions 171a are arranged at a predetermined interval so as to be attached to the top wall portion 171 of the guide rail 170 with a closer 230 (described later) entering from between the protruding wall portion 171a and the protruding wall portion 171a.

[0032] Also, small recesses 171as for holding the jig 300 (described later) without falling off when the jig 300 is detachably attached to the guide rail 170 are respectively formed at predetermined positions on the inner surfaces of the two protruding wall portions 171a facing each other.

[0033] The pair of side wall portions 172 of the guide rail 170 are plate-like members having a length in the vertical direction (arrow ef direction) such that the lower end surface of the flange wall portion 173 and the lower end surface 111c of the upper frame 111 are flush.

[0034] The pair of flange wall portions 173 of the guide rail 170 are portions that extend from the lower end edges of the pair of side wall portions 172 in a state parallel to the top wall portion 171 and approaching each other, and are spaced apart in a facing state, and have a rolling surface on which the tire 193 of the moving roller 190 rolls.

[0035] Note that both the pair of side wall portions 172 and the pair of flange wall portions 173 extend in the longitudinal direction in the same manner as the top wall portion 171. The guide rail 170 holds the moving roller 190 in a state where the moving roller 190 is accommodated in its substantially inverted U-shaped inner accommodation space so as to be movable along the guide rail 170.

[0036] <Moving roller> As shown in FIG. 2, the moving roller 190 is attached to the upper end surface (hereinafter referred to as the "upper end surface") of the first door body 130, and is located at a substantially central position in the left-right direction.

[0037] This moving roller 190 is rotatably attached to the first door body 130 in the horizontal direction (arrow ab direction), and the main body 191 and the door engaging portion 195 rotate in accordance with the movement of the opening and closing of the first door body 130. Further, the moving roller 190 has four tires 193 and is attached to be movable in the opening and closing direction (arrow ab direction) inside the guide rail 170.

[0038] As shown in FIGS. 4(A) to (C), the moving roller 190 is composed of a main body 191 formed of metal, resin, or the like, and a door engaging portion 195 attached in a suspended state below the main body 191 (arrow f direction).

[0039] The main body 191 of the moving roller 190 has a substantially U-shaped cross section, and includes a bottom plate portion 191a extending in the longitudinal direction parallel to the ceiling surface 111u of the upper frame 111, and two side plate portions 191b, 191b standing upward (arrow e direction) from both end portions in the short direction of the bottom plate portion 191a.

[0040] The bottom plate portion 191a of the main body 191 has an end surface 191at on the door closing side (arrow a direction) of the bottom plate portion 191a. This end surface 191at of the bottom plate portion 191a is a portion that contacts the end surface 303a of the protruding portion 303 of the jig 300 described later. Further, an engaged portion 192 that engages with the latch 234 (FIG. 5) of the closer 230 is provided substantially at the center of the bottom plate portion 191a of the main body 191. This engaged portion 192 has an inverted U shape formed by bending after a part of the bottom plate portion 191a is cut off.

[0041] When the engaged portion 192 of the main body 191 of the moving roller 190 is caught by the latch 234 of the closer 230, the moving roller 190 is pulled in the door closing direction (arrow a direction) by the closer 230. Since the moving roller 190 is attached to the first door body 130, the first door body 130 is pulled by the closer 230 to a position where it is completely closed.

[0042] On the outside of the two side plate portions 191b, 191b of the main body portion 191, four tires 193 are rotatably supported. The inner space of the two side plate portions 191b, 191b has a width capable of accommodating the closer 230 (see FIG. 3), and also has a width capable of accommodating the jig 300 to be described later (see FIG. 7). That is, the inner space of the two side plate portions 191b, 191b functions as a closer accommodation space capable of accommodating the closer 230 and a jig accommodation space for the jig 300.

[0043] Thus, even when the moving roller 190 moves in the opening and closing direction (arrow ab direction) with respect to the guide rail 170, the closer 230 can enter the inner space of the moving roller 190 without interference between the closer 230 and the two side plate portions 191b, 191b.

[0044] The door engaging portion 195 of the moving roller 190 is attached in a state of being embedded at a position substantially in the center in the left - right direction (arrow ab direction) on the upper end surface of the first door body 130 (FIG. 2). This door engaging portion 195 has an attachment portion 196 for attaching to the first door body 130 and a rotation shaft 197 that rotatably supports the moving roller 190 in accordance with the movement of the first door body 130.

[0045] <Fixed roller> On the upper end surface of the second door body 150 and on the suspension side at the right - hand end, a fixed roller 210 is attached. Since the fixed roller 210 has the same structure as the moving roller 190, the description thereof is omitted here.

[0046] Similar to the moving roller 190, the fixed roller 210 is rotatably attached to the second door body 150 in the horizontal direction (arrow ab direction) and rotates in accordance with the opening and closing movement of the second door body 150. Note that, unlike the moving roller 190, the fixed roller 210 is fixed so as not to move with respect to the right - hand end of the guide rail 170.

[0047] <Closer> As shown in FIG. 5, when closing the first door body 130 and the second door body 150, when closing, the latch 234 of the closer 230 captures the engaged portion 192 of the moving roller 190, thereby pulling the first door body 130 and the second door body 150 with respect to the frame body 110 until they are completely closed. Note that when the first door body 130 and the second door body 150 are closed forcefully, the closer 230 also dissipates the momentum and moves to a position where it closes gently.

[0048] The closer 230 mainly has a main body portion 231, a capturing portion 235, a damper 237, and a spring member 239. The main body portion 231 of the closer 230 is a rectangular cross-sectional square tube member extending along the longitudinal direction of the guide rail 170 (arrow ab direction), and houses the latch 234 of the capturing portion 235, the damper 237, the spring member 239, etc. in its inner space.

[0049] The main body portion 231 of the closer 230 has a through hole 231a penetrating along the vertical direction (arrow ef direction) at the end on the left side, which is the door closing side (arrow a direction), and a through hole 231b penetrating along the vertical direction (arrow ab direction) at the end on the right side, which is the door opening side (arrow b direction). These through holes 231a and 231b are used to attach and fix the closer 230 to the top wall portion 171 of the guide rail 170.

[0050] The capturing portion 235 of the closer 230 has a link pin 233 that moves along an L-shaped guide hole 232 formed with respect to the side surface of the main body portion 231, and a latch 234 that is provided integrally with the link pin 233 and engages with the engaged portion 192 of the moving roller 190.

[0051] The damper 237 of the closer 230 is a buffer member that reduces the momentum when the first door body 130 and the second door body 150 are closed. When the latch 234 of the catching portion 235 and the engaged portion 192 of the moving roller 190 are engaged, the spring member 239 of the closer 230 draws in the moving roller 190 by the biasing force of the spring member 239. At this time, the damper 237 can absorb the momentum in the direction of drawing in the moving roller 190 by the spring member 239.

[0052] <Fixture> As shown in FIGS. 6(A) and (B), the fixture 300 is a tool for determining the optimal attachment position of the closer 230 with respect to the guide rail 170 in order to completely close the first door body 130 and the second door body 150 attached to the guide rail 170 of the upper frame 111 in the frame body 110.

[0053] The fixture 300 is generally made of metal, resin, etc. having a substantially rectangular parallelepiped shape, and is composed of a rectangular parallelepiped main body portion 301 and a protruding portion 303 protruding downward (in the direction of arrow f) at one end in the longitudinal direction of the main body portion 301.

[0054] As shown in FIG. 7, the main body portion 301 of the fixture 300 has a lateral width smaller than the width between the side plate portions 191b of the main body portion 191 of the moving roller 190 and slightly smaller than the width between the protruding wall portions 171a of the guide rail 170.

[0055] Further, the main body portion 301 has a protruding portion 302 that can be inserted between the two protruding wall portions 171a of the guide rail 170 and is fitted into the recess 171as of the protruding wall portion 171a when the main body portion 310 is inserted and attached between the two protruding wall portions 171a.

[0056] The protruding portion 302 is provided at positions on both side surfaces of the main body portion 301 of the jig 300 that face away from each other, and has a size and a length in the horizontal direction (arrow ab direction) that can fit into the recess 171as of the protruding wall portion 171a in the guide rail 170.

[0057] In addition, the protruding portion 303 provided at one end of the main body portion 301 has a rectangular parallelepiped shape, is a portion that protrudes downward (arrow f direction) from the lower surface 301b of the main body portion 301, and is provided integrally with the main body portion 301.

[0058] The end face 303a on the right side (arrow b direction) of this protruding portion 303 is flush with the main body portion 301, and is a portion that contacts the end face 191at on the left side (arrow a direction) of the bottom plate portion 191a of the main body portion 191 in the moving roller 190 (Fig. 4).

[0059] Furthermore, a through hole 305 penetrating along the vertical direction (arrow ef direction) is provided at the other end of the main body portion 301. The inner diameter of this through hole 305 is formed larger than that of a drill pin 400 (Figs. 10 to 12) described later.

[0060] A predetermined distance is provided between the through hole 305 of the main body portion 301 and the end face 303a of the protruding portion 303. This distance is a value considered to be the optimal position where the closer 230 can pull in the moving roller 190 and completely close the first door body 130 when the closer 230 is attached to the guide rail 170 using the jig 300.

[0061] That is, when the closer 230 is arranged at a position where the first door body 130 is completely closed, based on the dimension in the longitudinal direction of the moving roller 190 and the positional relationship of the through hole 231a for attaching the closer 230 to the guide rail 170, the distance between the through hole 305 of the main body portion 301 and the end face 303a of the protruding portion 303 is determined.

[0062] <Procedure for attaching the closer using the jig> Next, an attachment procedure for attaching the closer 230 to the guide rail 170 of the folding door device 100 at an optimal position will be described. For ease of viewing, the first door body 130 and the second door body 150 are not shown in FIGS. 8(A) to 12(A), and the guide rail 170 is not shown in FIGS. 8(B) to 12(B).

[0063] As shown in FIGS. 8(A) and (B), as a first step, a semi-door open state in which the first door body 130 and the second door body 150 are folded with respect to the frame body 110 of the folding door device 100 via the upper hinge 141 and the lower hinge 143 is formed. Then, the jig 300 is attached to the guide rail 170 so as to be disposed on the door closing side (in the direction of arrow a), which is the left side for the moving roller 190 attached to the first door body 130.

[0064] In this case, the jig 300 is held without falling from the guide rail 170 when the protruding portion 302 of the main body portion 301 fits into the recess 171as of the protruding wall portion 171a of the top wall portion 171 of the guide rail 170.

[0065] Here, the jig 300 is disposed so as to be in contact with the moving roller 190. Specifically, it is disposed in a state where the end face 303a (FIG. 6) of the protruding portion 303 of the jig 300 is in contact with the end face 191at (FIG. 4) of the bottom plate portion 191a of the main body portion 191 of the moving roller 190.

[0066] Next, as shown in FIGS. 9(A) and (B), as a second step, a state in which the first door body 130 and the second door body 150 are completely closed is formed from the semi-door open state of the first door body 130 and the second door body 150. At this time, since the jig 300 is in contact with the moving roller 190, it will be pushed in the door closing side (in the direction of arrow a) by the moving roller 190 and moved along the guide rail 170.

[0067] Subsequently, as shown in FIGS. 10(A) and (B), as the third step, when the half-door open state of the first door body 130 and the second door body 150 is formed again from the state where the first door body 130 and the second door body 150 are completely closed, since only the jig 300 is in contact with the moving roller 190, only the jig 300 is left in place.

[0068] The position of the through hole 305 of the jig 300 left on the guide rail 170 should correspond to the through hole 231a of the main body portion 231 of the closer 230 when the closer 230 is attached to the guide rail 170. That is, if the through hole 231a of the closer 230 is made to correspond to this position and attached to the top wall portion 171 of the guide rail 170, the first door body 130 and the second door body 150 can be completely closed with respect to the frame body 110 by the closer 230.

[0069] Therefore, the operator can use the through hole 305 of the jig 300 to drive the drill screw 400 into the top wall portion 171 of the guide rail 170 to form a pilot hole 171c (FIG. 11(A)) for attaching the closer 230 to the top wall portion 171.

[0070] As shown in FIGS. 11(A) and (B), as the fourth step, when the drill screw 400 is removed from the jig 300, the jig 300 is removed from the guide rail 170, and the through hole 231a of the main body portion 231 of the closer 230 is arranged to face the pilot hole 171c provided in the top wall portion 171 of the guide rail 170 in the vertical direction (arrow ef direction).

[0071] As shown in FIGS. 12(A) and (B), as the fifth step, with the positions of the through hole 231a of the main body portion 231 of the closer 230 aligned with the pilot hole 171c provided in the top wall portion 171 of the guide rail 170, the main body portion 231 of the closer 230 is attached to the top wall portion 171 and the upper frame 111 by the drill screw 400.

[0072] Further, although a lower hole is not formed at the position of the top wall portion 171 of the guide rail 170 facing the through hole 231b of the main body portion 231 in the closer 230, the main body portion 231 is directly attached to the top wall portion 171 and the upper frame 111 by the drill bit 400.

[0073] As a result, the closer 230 is attached and fixed to an optimal position where the first door body 130 and the second door body 150 can be completely closed with respect to the top wall portion 171 of the guide rail 170 and the upper frame 111.

[0074] <Function and Effect> According to the above configuration, the jig 300 can easily determine the optimal position of the guide rail 170 where the engaged portion 192 of the moving roller 190, the closer 230, and the latch 234 are engaged and the closer 230 pulls in the first door body 130 and the first door body 130 and the second door body 150 are completely closed with respect to the frame body 110.

[0075] As a result, even when the lateral widths of the upper frames 111 of the frame body 110 are individually different, it is not necessary to perform complicated operations such as individually and specifically calculating the optimal position for attaching the closer 230 according to the guide rail 170 of each upper frame 111 and creating a design drawing. Thus, just by the operator using the jig 300 on site, the optimal attachment position of the closer 230 can be determined instantaneously, and the lower hole 403 can be formed.

[0076] In addition, the jig 300 presents an optimal attachment position to the top wall portion 171 of the guide rail 170 through the through hole 305 of the main body portion 301, and at the same time, the drill bit 400 can be driven using this through hole 305, so that the lower hole 171c can be efficiently formed.

[0077] 3. Other Embodiments In the above-described embodiments, the jig 300 of the present invention is applied to the folding door device 100 using the first door body 130 and the second door body 150 with respect to the frame body 110. However, the present invention is not limited to this, and it may be applied to a sliding door device having a single door.

[0078] Also, in the above-described embodiments, the case where the closer 230 is attached to a predetermined position on the left side of the guide rail 170 has been described. However, the present invention is not limited to this, and a closer (not shown) may be attached using the jig 300 at an optimal position on the right side of the guide rail 170 in order to fully open the first door body 130 and the second door body 150.

[0079] In addition, those skilled in the art can appropriately modify the jig of the present invention according to conventionally known knowledge. As long as the configuration of the present invention is still provided by such modifications, of course, it is included in the scope of the present invention.
