Description

[Detailed description of the invention] [Technical field] The present invention relates to a temporary lock structure for a bifold door installed in an opening of a bathroom unit, etc., to prevent intrusion from the outside during the construction period. It is an idea.

[Background Art] It has been known to attach a bifold door to an opening of a bathroom unit. In the case of conventional bifold doors, the door bodies are pivotally supported by hinge bodies, and the upper and lower ends of one door body on the side opposite to the connection side with the hinge body are pivotally supported to the upper and lower rails. The running bodies provided above and below the end opposite to the hinge body of the other door body are fitted into the upper and lower rails so as to be freely movable. Then, a lock pin is inserted into the cylindrical hinge body, which is a part of the component that constitutes the bifold door, so as to be able to move up and down, and the lock pin is made to protrude from the longitudinal end of the hinge body and plunge into the rail. It is designed to maintain the front closed state of the bi-folding door. However, with this kind of configuration, 2
When a bifold door is constructed at a construction site, there is a risk that during construction, someone could easily grab the operating part for raising and lowering the lock pin from the outside and easily release the lock and enter the bathroom unit, staining the interior of the bathroom unit. It was hot.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to be able to maintain the locked state of the lock pin using the lock screw in locations that cannot stand on their own during construction. This prevents the lock pin from being released even if the user tries to release the lock pin by grasping the operation part during construction, and prevents people from entering and contaminating the interior during construction. Also, after construction is completed, the lock screw can be removed and the lock pin cannot be unlocked. To provide a temporary locking structure for a bifold door which allows locking and unlocking using a normal locking pin only by operating a part.

[Disclosure of the invention] The temporary locking structure of the bifold door of the present invention is such that in the bifold door 4 in which the door bodies 1 and 2 are pivotally supported by the hinge body 3, the lock pin 5 inserted into the bifold door 4 is The folding door 4 can be inserted into the rail 6 from the vertical end thereof, and is provided with an operating section 7 for vertically moving the lock pin 5.
The lock screw 8 is screwed in from near the vertical end of the folding door 4 and is screwed into the lock pin 5, and by adopting such a configuration,
The above-mentioned purpose of the present invention has been achieved.
In other words, in the present invention, unless the lock pin is released from the lock screw 8, the operating portion 7
Even if the lock pin 5 is operated, the lock by the lock pin 5 cannot be released, so it is now possible to prevent people from entering the interior by operating the operation part 7 during work, and the lock screw 8 is Since it is attached to the end of the direction, it is difficult to stand on its own and is located in a difficult to understand position, and there is no risk of the lock screw being accidentally removed.

The present invention will be explained in detail below with reference to examples. The bifold door 4 is constructed by rotatably supporting two door bodies 1 and 2 by a cylindrical hinge body 3. That is, the shaft portions 1 provided at the side ends of the door bodies 1 and 2 are inserted into the bearing groove portions 9 provided on both sides of the hinge body 3.
By rotatably fitting the hinge body 3, the door bodies 1 and 2 are rotatably connected to each other by the hinge body 3. The runners 1 are visible from the upper surface of the ends of the two door bodies 1 and 2 opposite to the hinge body 3.
1 protrudes, and a downward pin 12 protrudes from the bottom surface. Each runner 11 and downward pin 12 are connected to the rail 6 (that is, the upper rail 6
a and the lower rail 6b), where the runner 11 and downward pin 12 on one side of the door body 1
A stopper member 13 is attached to the vicinity of the end of the upper and lower rails 6 with screws or the like so that the upper and lower rails 6a and 6b do not move along the upper and lower rails 6a and 6b. Therefore, the end of one door body 1 provided with the runner 11 and downward pin 12 does not move, but can only rotate around the runner 11 and downward pin 12, and the other door Runner 11 provided at the end of body 2
The downward pin 12 is adapted to move within the upper and lower rails 6a and 6b. Therefore, the runner 11 and downward pin 12 provided on the other door body 2 serve as a running body that runs on the rail 6. By the way, if it is desired to change the left-right orientation, the left-right orientation can be changed by removing the stopper member 13 and reattaching it so that the other runner 11 and downward pin 12 cannot be moved. A lock pin 5 is inserted into the cylindrical hinge body 3 so as to be vertically movable. Further, the end of the lock pin 5, which is vertically movable, can be inserted into the rail 6.
In the embodiment shown in the accompanying drawings, the locking pin 5 is attached to the lower rail 6.
It is possible to rush into b. An operating section 7 is attached to the lock pin 5. This operating portion 7 is arranged so as to protrude from the outer surface of the hinge body 3. That is, the shafts 14 of the front and back operating parts 7 are inserted into the holes 16 of the connecting parts 15 provided on the lock pin 5 so that the shafts 14 face each other, and the screws 17 are inserted from one of the operating parts 7 through the shafts 14. The operating section 7 and the lock pin 5 are connected by screwing into the shaft body 14 of the other operating section 7. The locking pin 5 is provided with a bifurcated resilient locking portion 18, and the locking portion 18 can be elastically locked to a locked portion 19 made of a pin stretched within the hinge body 3. ing. For this reason, when the operation part 7 is operated to pull up the lock pin 5 and the lock pin 5 is pulled out from the lower rail 6b, the locking part 18 is elastically locked to the locked part 19, and the lock by the lock pin 5 is released. It is starting to be retained. In addition, when the locking part 18 is locked to the locked part 19 and the operating part 7 is operated to pull down the lock pin 5 against the elastic locking force, the tip of the lock pin 5 will be inside the lower rail 6b. We are starting to enter into Note that the shaft body 14 protruding from the operating portion 15 moves up and down within a vertically elongated hole 20 provided in the hinge body 3. A cover material 21 is attached to the upper and lower surfaces of the door bodies 1 and 2 over the entire length in the longitudinal direction, and a support portion 22 is protruded from each end of the cover material 21 on the hinge body 3 side. One end of the support portion 22 has a recess 23 and the other a protrusion 24, and when the bifold door is fully closed, the recess 23 and the protrusion 24 fit together as shown in Figure 5. . This support portion 22 faces a part of the end surface of the cylindrical hinge body 3 in the vertical direction, and prevents the hinge body 3 from coming off upward or downward. Here, as described above, the support part 22 only faces a part of the end surface in the vertical direction of the hinge body 3, and does not face the part of the hinge body 3 through which the lock pin 5 is inserted. 5 rail 6
The cover material 21 is designed so that it does not get in the way when moving to the side. Near the upper end to the lower end of the hinge body 3 (near the lower end in the embodiment shown in the drawings)
A hole 25 is drilled in the lock pin 5, and a screw hole 26 is provided in the lock pin 5. In the embodiment shown in the attached drawings, the door bodies 1 and 2 are provided with a locking roller 27 that is elastically biased downward or upward by an elastic force. 27 is designed to be inserted into the upper rail 6a and the lower rail 6b to maintain the closed state, and when the handle 28 provided on the door body 2 is held by hand to open the bifold door, the above-mentioned elastic locking is applied. Rail 6 of roller 27
It is pulled open with a force that overcomes the elastic locking force.

In addition, there is a space of approximately Z inside the cylindrical frame 29 of the door bodies 1 and 2.
The frame 29 is provided with a recess 30 and a contact portion 31, and the Z-shaped reinforcing metal fitting 32 is provided with an elasticity.
9, the opening angle of both side pieces 34 with respect to the central piece 33 is set to 90° or more, and one side piece 34 is elastically fitted into the recess 30 while the tip of the other side piece 34 is brought into elastic contact with the abutment portion 31, so that the reinforcing metal fitting 32 can be fitted in so as not to move within the cylindrical frame 29. In this way, the frame 29 made of synthetic resin or the like can be firmly reinforced by the reinforcing metal fitting 32. In this case, fitting one side piece 34 into the recess 30 prevents the reinforcing metal fitting 32 from falling in the direction of the arrow A in FIG.
The other side piece 34 abuts against the reinforcing metal fitting 32.
This can prevent the movable member from moving in the direction of the arrow B in FIG.

Therefore, the bifold door with the above structure is used, for example, as a door for the opening of a bathroom unit, and in order to prevent unauthorized persons from entering the bathroom unit during construction, it is necessary to
With the folding door closed forward, the end of the lock pin 5 is inserted into the rail 6 to lock it, and in this locked state, the lock screw 8 is further inserted through the hole 25.
is inserted, and the tip of the lock screw 8 is screwed into the screw hole 26. By preventing the lock pin 5 from moving in the vertical direction with the lock screw 8 in this way, the lock pin 5 will not move even if the operating section 7 is operated, so that an unrelated person can open the bifold door and view the inside during construction. It has become impossible to contaminate it. When the construction is completed, the lock screw 8 is removed and the lock pin 5 can be moved up and down using the operating section 7. The hole 25 remaining after the lock screw 8 is removed is covered with tape of the same color as the hinge body.

[Effects of the invention] In the present invention, as described above, the lock pin inserted into the bifold door can be inserted into the rail from the vertical end of the bifold door, and the vertical movement of the lock pin can be controlled. With the lock pin protruding into the rail, the lock screw is screwed into the lock pin from near the vertical end of the bifold door. Even if the lock pin is operated, the lock by the lock pin cannot be released, so it is now possible to prevent people from entering the interior by operating the operation part during work. Since the locking screw is attached to the locking section, it is difficult to stand on its own and is located in an incomprehensible position, and there is no risk of the locking screw being accidentally removed.
