Description

[Detailed description of the invention] This invention is based on vertical frames 2 facing each other between adjacent doors 1 and 1.
A pair of locking protrusions 6, 6 are vertically provided on the opposing side surfaces of one of the vertical frames 2a, 2b, and a hook 3 is provided between the locking protrusions 6, 6, A locking recessed groove 8 into which the locking protrusions 6, 6 fit is provided in the opposing side surface of the frame 2b, and a movable hook 4 that can be freely engaged with and detached from the hook 3 is provided in the locking groove 8. The lever 5 of the movable hook 4 that releases the engagement with the movable hook 4 is disposed on the door 1 on the side of the movable hook 4 so as to be exposed to the indoor side. The doors can be connected to each other when closed, providing good security and wind protection, and when opening the door, each door can be pulled and stored in the door pocket while standing next to the door pocket, making it easy to open the door. to provide connecting devices.

The present invention will be explained in detail below based on the illustrated embodiments.

Each door 1 has a hook 3 attached to a vertical stile 2a on one side and a movable hook 4 attached to a vertical stile 2b on the other side.
As shown in the diagram, adjacent doors 1 and 1 have vertical stiles 2a,
2 b face each other.

Two locking protrusions 6, 6 are provided on the opposing sides of the vertical stile 2b over the entire length of the top and bottom, and as shown in FIG. Fixing part 2 of hook 3 to 2a
6 is attached with screws 27.

The hook 3 has an oval shape as shown in FIG. 3, and the outer surface of the tip has a rounded surface 7 for guiding.

The vertical stile 2b has locking protrusions 6, 6 on the opposite sides as shown in FIG.
It is a hollow body provided with a locking groove 8 that can be inserted into.

Figure 2. In FIG. 4, reference numeral 9 denotes a movable hook support, which is fitted into the hollow part 10 of the vertical stile 2b through the through hole 12 of the outer wall 11.

Denoted at 13 are locking claws protruding from both upper and lower surfaces of the movable hook support 9, which lock onto the upper and lower edges of the through hole 12 from inside to prevent the movable hook support 9 from coming off.

A slide body 15 is housed within the movable hook support body 9 so as to be urged upward by a spring 14.

The movable hook 4 extends from the front surface of the slide body 15 and has an oval shape, and the outer surface of the upper end of the movable hook 4 has a rounded surface 16.

This movable hook 4 is attached to the slide hole 1 of the movable hook support 9.
7 and protrudes into a locking groove 8 on the opposing surface of the vertical stile 2b so as to face the hook 3.

A lever 5 is extended from the back side of the slide body 15.

This lever 5 passes through a through hole 19 in the inner wall 18 of the stile 2b and is exposed to the back side of the panel 20 of the door 1, that is, to the indoor side of the door 1.

In addition, contrary to the above embodiment, the hook 3 may be attached to the vertical stile 2b and the movable hook 4 may be attached to the vertical stile 2a, or the hook 3 and the movable hook 4 may be attached upside down.

However, when the door 1... is pulled out from the door pocket 24 and moved toward the door stop 25 along the upper and lower rails 22, 23 to close it, the vertical stile 2a of the previously closed door 1 is moved next. Hook 3 just before the vertical stile 2b of door 1 hits
The rounded surface 16 of the movable hook 4 first comes into contact with the rounded surface 7 of the movable hook 4, and a downward sliding force is generated, and the movable hook 3 and the slide body 15 are pushed down against the spring 14, and the hook 3
After passing, the movable hook 4 is pushed up by the upward elastic force of the spring 14 and engages with the hook 3, and at the same time, the locking protrusions 6, 6 are inserted into the locking groove 8. Doors 1 and 1 are automatically connected to each other as they enter.

6th door where all doors 1... are connected to each other
When opening each door 1 from the closed state shown in FIG. 6, as shown in FIG. Push down the movable hook 4 against the
4. Separate door 1 from the adjacent door 1.

By repeating this operation sequentially, it is possible to stand next to the door pocket 24 and pull all the doors 1 while connected and store them in the door pocket 24 one after another, as shown in FIG. 6C to e. can.

FIG. 7 shows another example of a hook 3 and a movable hook 4, in which the movable hook 4 is pivotally supported on a movable hook support 9 so as to be rotatable up and down, and is resiliently urged downward by a spring 14. By pushing down the lever 5, the movable hook 4 can be rotated upward and removed from the upward hook 3.

The movable hook 4 shown in FIG. 8 is similar to the movable hook 4 shown in FIG. 7 in that a torsion coil spring is used as the spring 14 to spring the movable hook 4 downward.

In both of the above embodiments, the lever 5 may be of a rotary knob type as shown in FIG.

FIG. 10 shows a combination of a hook 3 having a fixed portion 36 that can be fitted into one of the vertical frames 2 a and 2 b, and a movable hook 4 that can be freely engaged and detached from the hook 3 by vertical movement or vertical rotation.

In this invention, a hook is provided on one of the vertical stiles facing each other between adjacent doors in a diagonal manner, and a movable hook that can be freely engaged with and detached from this hook is provided on the other vertical stable. When the doors of the body are closed, the doors can be connected to each other and each door can be held without rattling, and when all the doors are connected and opened from the closed state, it is possible to hold all the doors by standing next to the door pocket. This has the advantage that the doors can be easily stored by pulling the sheets together and sequentially uncoupling them and storing them one by one in the door pocket.

In addition, since the lever for releasing the movable hook from the hook is exposed on the indoor side of the door, it is easy to separate the doors from each other, which has the advantage of making the above-mentioned door storage operation easier.

In addition, a pair of locking protrusions are vertically provided on the opposing side surfaces of one of the vertical stiles facing each other between adjacent doors, and a hook is provided between the locking protrusions, and a hook is provided between the locking protrusions. A locking groove into which the locking protrusion fits is provided on the opposite side of the stile, and a movable hook that can be freely engaged and detached from the hook is provided in the locking groove. The movable hook can be hidden from view, giving it a good appearance. When the movable hook is locked to the hook, the movable hook completely fits into the locking protrusion and the locking groove and moves outward. Not exposed at all
It is not possible for a person outside the door to insert a metal fitting between the opposing side surfaces of both stiles to directly remove the movable hook from the door, and it has good security and is resistant to external forces in the direction in which the door runs. The hooks engage with the movable hooks to prevent the doors from coming off each other, and the locking protrusions engage with the opposing vertical stile to prevent the doors from coming off against external forces in the direction perpendicular to the door surface. This means that the doors can be firmly connected to each other to prevent wind and wind.
This has the advantage of further improving crime prevention.
