Opening and closing body device and hanging device used in the opening and closing body device

  The present invention relates to an opening / closing body device for suspending an opening / closing body such as a sliding door or a folding door movably to a guide body, and a hanging device used in the opening / closing body device.

  Conventionally, an opening / closing body that opens and closes an opening of a building, for example, a fixing portion is provided at the upper end of a hanging door, and a traveling body is supported on an upper rail installed along the upper side of the opening, and the fixing provided on the hanging door What attaches a part to a traveling body and suspends and holds a suspension door on an upper rail is known (for example, refer to patent documents 1).

However, conventionally, when suspending a hanging door on the upper rail, while lifting the hanging door, a saddle that protrudes below the traveling body is inserted from the lateral direction and attached to the recessed portion that opens in the lateral direction of the fixing portion. Therefore, the suspension door is heavy, and at this time, it is difficult to align the eaves portion of the traveling body and the recessed portion of the fixing portion. In particular, since the flange portion of the traveling body is inserted and attached to the recessed portion of the fixing portion from the lateral direction, the height of the fixing portion with respect to the traveling body needs to be made uniform, and if the heights are not uniform, attachment becomes impossible. Therefore, it is conceivable that the traveling body and the fixed portion are integrally attached to the suspension door in advance, and the traveling body provided on the suspension door side is put in the upper rail, but in this case, the lateral direction of the upper rail There is also a problem that it is difficult to align the traveling body and the upper rail, and in this case, part of the upper rail is cut and the traveling body is inserted, and then the upper rail is cut. Since it is necessary to connect places, there is a problem that a part of the upper rail has a seam and rattling occurs when the hanging door is running.

  In this example, the introduction part 9, the retaining part 11 and the temporary holding part 10 are constituted by a pair of left and right clamping pieces 10A. The pair of left and right sandwiching pieces 10 </ b> A is made of an elastically deformable spring material, and is disposed in a recess 17 that is provided in the fixing portion 6 and opens in the lateral direction. Each sandwiching piece 10 </ b> A is supported by the back wall of the recess 17 so as to be openable and closable in a direction in which the sandwiching pieces 10 </ b> A contact and separate from each other. Between the rear ends of the pair of sandwiching pieces 10A is a shaft body relief hole 18 of the shaft body 7A, and the front side of the shaft body relief hole 18 is a temporary holding portion 10 having a substantially C-shape in plan view. The temporary holding part 10 is opened larger than the shaft body escape hole 18 so that the collar part 7B is temporarily held in a state in which it can move up and down. An introduction portion 9 is opened through a retaining portion 11 in front of the temporary holding portion 10. The spacing d of the retaining portions 11 is narrower than the spacing between the introducing portions 9 and the temporary holding portions 10, and the retaining portions 11 are smoothly continuous with respect to the introducing portions 9 and the temporary retaining portions 10. It has a shape. As a result, the flange portion 7B introduced from the introduction portion 9 can be horizontally inserted while expanding the retaining portion 11 and can be inserted into the temporary holding portion 10. At this time, the flange portion 7B is inserted into the temporary holding portion 10. Sometimes a click sound (engagement sound) is generated by closing the pair of sandwiching pieces 10A made of a spring material. After being inserted into the temporary holding part 10, the collar part 7 </ b> B is prevented from coming out of the temporary holding part 10 by the retaining part 11. In this example, as shown in FIG. 1A, the dimension E in the vertical direction B of the introduction part 9, the retaining part 11 and the temporary holding part 10 is set to be twice or more the dimension e in the vertical direction B of the flange part 7B. ing.

  The main fixing portion 12 connected to the lower side of the temporary holding portion 10 is for fixing the collar portion 7B in the vertical direction B and the horizontal direction A. In this example, the main fixing portion 12 is arranged below the temporary holding portion 10. The elastic lock piece 12 </ b> A and the return spring 19 disposed below the elastic lock piece 12 </ b> A. Both sides on the center side of the elastic lock piece 12A are rotatably supported by locking holes provided on both sides on the lower side of the recess 17 of the fixing portion 6. The rear end portion of the elastic lock piece 12A covers the lower opening of the temporary holding portion 10 and protrudes to the extent that the shaft body escape hole 18 is not blocked. When the opening / closing body 2 is lifted with the flange portion 7B inserted into the temporary holding portion 10, the adhering portion 6 is lifted so that the flange portion 7B pushes open the elastic lock piece 12A and at the same time the shaft body 7A is released from the shaft body escape hole. 18 and the elastic lock piece 12A is returned upward by the return spring 19 after the collar portion 7B moves downward from the rear end portion of the elastic lock piece 12A, whereby the rear end portion of the elastic lock piece 12A Is engaged with the upper surface portion of the flange portion 7B. At this time, a click sound (engagement sound) is generated by the elastic lock piece 12A, and the return of the flange portion 7B is prevented by the elastic lock piece 12A. In contrast, the fixing portion 6 can be permanently fixed in the vertical direction B and the horizontal direction.

In the present invention , the operation portion 20 that can be operated from the outside with a fingertip is provided at the front end of the elastic lock piece 12A, and when the operation portion 20 is pushed up by the fingertip, the rear end portion of the elastic lock piece 12A is a return spring. It is pushed down against 19 so that the collar portion 7B can be pulled out above the elastic lock piece 12A.

  Next, the attaching operation of the opening / closing body 2 will be described. First, the operation when the opening / closing body 2 is composed of a sliding door (single door) 2A will be described. First, as shown in FIGS. 6 (a) and 6 (b), the traveling body 5 is engaged with the upper rail 3 </ b> A, and the lower support body 21 including the tension rod 21 </ b> A is disposed on the floor of the opening 1. When the tip of the tension bar 21A is turned in the arrow direction b in FIG. 6B, the tip protrudes in the arrow direction c and can be fixed, and can be removed by the reverse operation. In the first step, as shown in FIG. 6C, when the sliding door 2A is slanted and its lower end is pressed against the lower support 21 and the sliding door 2A is erected with the lower support 21 as a fulcrum, The part 6 moves horizontally toward the collar part 7B. At this time, as shown in FIG. 4, the collar portion 7B is aligned with the introduction portion 9 of the fixing portion 6, and the upper end portion of the sliding door 2A is pushed in this state as shown in FIG. 1 (a) → (b). The flange portion 7B is pushed from the introduction portion 9 toward the temporary holding portion 10 in the horizontal direction A (direction orthogonal to the upper rail 3A) and temporarily held (the state shown in FIG. 5), and the retaining portion 11 can be retained. Here, the temporary holding state refers to a state where it cannot be removed unless a large force is applied. Accordingly, the builder can release his / her hand from the opening / closing body 2 in the temporary holding state. Thereafter, the sliding door 2A is fully fixed by lifting the sliding door 2A in the second step. That is, as shown in FIG. 1C, the collar portion 7B temporarily held by the temporary holding portion 10 pushes open the rear end portion of the elastic lock piece 12A and enters below the elastic lock piece 12A, and further the shaft body 7A. After the shaft enters the shaft body escape hole 18, the elastic lock piece 12A is returned to its original position by the return spring 19, whereby the elastic lock piece 12A is engaged and held at a part of the peripheral edge of the flange portion 7B. Since the remaining part is hooked on the lower end 10a of the temporary holding part 10, the return of the collar part 7B is prevented. As a result, the adhering portion 6 is permanently fixed to the traveling body 5 in the vertical direction B and the horizontal direction A (the state shown in FIGS. 2 and 3), and the hanging operation of the sliding door 2A is completed.

  Next, the case where the opening / closing body 2 includes the folding door 2B will be described. In addition, the basic operation | movement which the collar part 7B moves to the introduction part 9-> retaining part 11-> temporary holding part 10-> this fixing part 12 is the same as that of the said sliding door 2A. First, as shown in FIG. 7A, the pair of traveling bodies 5 are engaged with the upper rail 3A, and the fixing portions 6 are respectively attached to the upper ends of the two plate bodies 27 and 28 constituting the folding door 2B. Prepare it. In addition, the lower support body 21 which consists of the tension rod 21A shown in FIG.6 (b) on the floor | bed of the opening part 1 is arrange | positioned. In the first step, as shown in FIG. 7B, the folding door 2B is opened and the lower ends of the two plates 27 and 28 are supported by the lower support 21, and a pair of fixings are performed while supporting the load. It arrange | positions so that a pair of traveling body 5 may be put between the parts 6. FIG. When the folding door 2B is folded in this lower support state, as shown in FIG. 7 (c), the pair of traveling bodies 5 are moved inward by the pair of fixing portions 6, and as shown in FIG. 7 (d) The folding door 2B is folded until the traveling bodies 5 of the two abut each other. Then, one brim part 7B attached to one traveling body 5 is aligned with the introduction part 9 of one fixing part 6, and the other brim part 7B attached to the other traveling body 5 is aligned with the other fixing part 6. The pair of traveling bodies 5 are brought into a stationary state by the abutment of the projecting portions 15 by pressing the folding door 2B in the folding direction as shown in FIG. As shown in (a) → (b), one flange portion 7B is pushed in the horizontal direction A (in a direction parallel to the upper rail 3A) from the introduction portion 9 of the corresponding fixed portion 6 into the temporary holding portion 10. Can be temporarily held and can be prevented by the retaining portion 11, and at the same time, the other flange 7 </ b> B can be temporarily retained by the corresponding temporary retaining portion 10 and can be retained by the retaining portion 11. It can be prevented from coming off. In this temporary holding state, the builder can release his / her hand from the opening / closing body 2. Thereafter, in the second step, as shown in FIG. 8 (b), the folding door 2B folded in the temporary holding state is lifted upward, so that each of the flanges 7B is in a fully fixed state as described above (FIG. 2, FIG. 3), and the lifting operation of the folding door 2B is completed.

  Thus, even when the opening / closing body 2 is the sliding door 2A or the folding door 2B as described above, the opening / closing body 2 is temporarily temporarily held from the horizontal direction, and then the vertical direction of the mounting portion 7 and the mounted portion 8 Unlike the case where the main part is fixed by inserting the mounting part from the lateral direction into the recessed part of the fixing part 6 while lifting the hanging door as in the prior art, the main fixing method is adopted by the relative movement of the main part. In the present invention, the height of the fixing portion 6 with respect to the traveling body 5 does not need to be uniform when temporarily held, and only the relative movement in the vertical direction of the attachment portion 7 and the attachment portion 8 is sufficient for the main fixation. Alignment between the mounting portion 7 and the main fixing portion 12 is also unnecessary. As a result, even one person can easily suspend the opening / closing body 2.

  Further, in this example, the temporary holding portion 10 is composed of a pair of left and right holding pieces 10A that hold the side surface of the flange portion 7B, and the main fixing portion 12 is an elastic lock piece that is engaged and held by the peripheral portion of the flange portion 7B. Since it is comprised by 12A, the temporary holding part 10 and this fixed part 12 are simply comprised by combining the clamping piece 10A which clamps the collar part 7B, and the elastic lock piece 12A which engages and holds the collar part 7B It is possible to simplify the structure of the fixing portion 6. In addition, the pair of sandwiching pieces 10A is made of an elastically deformable spring material, and the flange portion 7B can be sandwiched between the sandwiching pieces 10A by expanding the sandwiching piece 10A. The sandwiching piece 10A can be easily configured, and by making the pair of sandwiching pieces 10A elastically deformable, it is possible to easily cope with variations in the dimensions of the flange portion 7B, and the temporary holding portion 10 temporarily holds the flange portion 7B. Performance can be increased.

  Further, in this example, of the pair of left and right sandwiching pieces 10A, the interval d between the portions constituting the retaining portion 11 is narrower than the opening width of the introduction portion 9 and the temporary holding portion 10, and the introduction portion 9 and the temporary holding portion 10 are temporarily held. Since it is formed continuously with respect to the part 10, when the collar part 7 </ b> B is inserted, the retaining part 11 opens and can be inserted into the temporary holding part 10, and after the collar part 7 </ b> B is inserted into the temporary holding part 10. By closing the spring piece, the collar portion 7B can be securely temporarily held by the temporary holding portion 10. In addition, since the portion constituting the retaining portion 11 is formed continuously with the introducing portion 9 and the temporary holding portion 10, the flange portion 7B from the introducing portion 9 to the temporary retaining portion 10 is simply opened. Therefore, the temporary holding operation can be performed easily and easily.

Further, in this example, the dimension E in the vertical direction B of each of the introduction part 9 and the temporary holding part 10 is set to be twice or more the dimension e in the vertical direction B of the flange part 7B . It becomes possible to sufficiently cope with uneven heights of the fixing portions 6. Furthermore, the holding piece 10A constituting the temporary holding portion 10 and the elastic lock piece 12A constituting the main fixing portion 12 each have a click function for generating a click sound when the collar portion 7B is engaged. Therefore, it is possible for the builder to confirm by hearing whether or not the temporary holding state has been reached and whether or not the present fixed state has been reached, and the suspension work of the opening / closing body 2 can be more easily performed while ensuring safety. it can.

  Further, it is desirable to provide a light-emitting part for position confirmation on the temporary holding part 10 and the main fixing part 12 in the attached part 8. In this case, the light emitting unit can be confirmed with light even in a dark site such as a storage, and functions to be easily constructed. The light emitting unit may be provided on only one or both of the temporary holding unit 10 and the main fixing unit 12, and in short, any light emitting unit may be used as long as the light emitting unit having a phosphorescent function can be illuminated in advance.

  In the above embodiment, the case where the pair of left and right sandwiching pieces 10 </ b> A constituting the temporary holding part 10 serves as the pair of left and right spring pieces constituting the retaining part 11 is exemplified. A pair of left and right spring pieces constituting the retaining part 11 are provided separately from the piece 10A, and the pair of spring pieces are pushed and opened by the movement of the flange part 7B. While being able to be comprised easily, the fall prevention effect of the collar part 7B can be heightened with a spring force.

In the above-described embodiment, the tension bar 21A is used as the lower support 21 that supports the lower end of the opening / closing body 2. However, as shown in FIGS. 9 to 12, when the lower rail 21B is installed, the tension bar 21A is It is unnecessary. That is, the lower rail 21 </ b> B functions as the lower support 21 in addition to guiding the lower runner attached to the lower end of the opening / closing body 2. For example, as shown in FIG. 9A, when the sliding door 2A (same as for the folding door 2B) is inclined and its lower end is inserted into the lower rail 21B, the sliding door 2A is raised with the lower rail 21B as a fulcrum. 9B, the fixing portion 6 moves toward the flange portion 7B, and the flange portion 7B is aligned with the introduction portion 9 of the fixing portion 6. In this state, the upper end portion of the sliding door 2A is moved. By pushing, the temporary holding state can be obtained as shown in FIGS. 1A to 1B, and the upper and lower rails 3A and 21B can be moved as shown in FIGS. Thus, the opening / closing body 2 can be supported. Therefore, the hanging work of the opening / closing body 2 can be easily performed using the lower rail 21B .

  The hanging tool 4 provided with the adhering portion 6 and the traveling body 5 according to the present invention is widely applied to all opening / closing bodies other than the sliding door 2A and the folding door 2B.
