Description

[Detailed Description of the Invention] Technical Field The present invention relates to a glass door frame for an opening/closing type door, and in particular, a locking member having a simple structure that allows each hanging member to move independently in opposition to each hanging member. The locking member is installed in the space of the door frame, and the locking member is fixed to the hanging member, so that the door frame can be easily attached to the hanging member, which not only simplifies construction but also reduces manufacturing costs. The present invention also relates to a glass door frame for an openable/closable door, which has improved adaptability to hanging members of various specifications.

Conventional technology Conventionally, glass door frames for retractable doors were
A locking member accommodated in a space formed in the door frame is attached to the hanging member with a mounting bolt, and moves integrally with the hanging member. However, the distance between the centers of the mounting holes for the mounting bolts of the hanging member varies depending on the specifications, and whenever the specifications of the hanging member change, the locking member must also be changed accordingly. If the locking member were simply made to move within the door frame, the locking member would slip and move on its own if the door frame was tilted during installation work, so it would be difficult to suspend the locking member. When attaching it to a member, it is necessary to move it to an appropriate position each time, which is very troublesome for the worker, and has the disadvantage that construction is not easy.

In order to eliminate such drawbacks, the applicant of the present application previously proposed the mounting holes for the mounting screws of the individual hanging members 10, as shown in FIG. 10a, a plurality of independently movable locking members 38 are provided in the space 2a formed in the door frame 2, and the locking members can be fixed to the hanging member 10 with mounting screws 16, Furthermore, when the distance between the centers of the mounting holes 10a of the mounting screws of the hanging member 10 changes, the locking member 38 can be simply moved using the tip of a screwdriver, etc., making installation of the door frame easier. Proposed.

However, when the locking member 38 is
In order to hold it in the space 2a formed in the space 2a, two parts, the mounting plate 31 and the elastic body 33, are required, which increases the manufacturing cost. Further, a mounting plate 31 for mounting the elastic body is press-fitted into the locking member 38, and the elastic body 31 is also press-fitted into the mounting plate.

The interval is larger than the longitudinal dimension of the locking member 38. For this purpose, the mounting hole 1 of the hanging member 10 is
When the distance between the centers of 0a is shorter than the distance between the screw holes 38a when two locking members 38 are connected,
The locking member had a drawback that it could not be used.

In addition, the applicant and the inventor of the present application have
An elastic body 43 and a locking member 48 as shown in the figure were devised and put into practical use; however, according to the locking member 48,
In order to hold the locking member in the space 2a formed in the door frame 2, two parts, a mounting plate 41 and an elastic body 43, are required.
8 and the mounting plate 41 require a process of fixing them by spot welding S, which has the drawback of further increasing manufacturing costs.

Purpose The present invention was made in order to eliminate the drawbacks of the prior art described above, and its purpose is to reduce the width of the hook portion formed on the upper part of the elastic body to the width of the hook portion formed on the door frame. The hook part is formed to have a dimension larger than the interval between the end faces of the bent part of the door frame, and the locking member is pushed up by the support part of the elastic body, and the bent part formed in the door frame is held under pressure between the hook part and the locking member. This reduces manufacturing costs by reducing the number of components for attaching the locking member to the space formed in the door frame by one compared to conventional products, and at the same time eliminating processing steps such as welding. In addition, the structure of the elastic body disposed for attaching the locking member to the door frame is greatly simplified, and the locking member is mainly attached to a part of the space formed in the door frame. To enable use for hanging members of various specifications regardless of the size of a space formed in a door frame so as to occupy the upper space.

Configuration In short, the present invention is such that a door frame attached to a glass for an openable door is attached to a hanging member, and a plurality of locks are arranged in a space formed in the door frame to face the hanging member. and an elastic body that elastically presses the locking member, the locking members each independently moving within the space of the door frame with an appropriate frictional force generated by the elastic body. In the structure, the width of the hook portion formed on the upper part of the elastic body is formed to be larger than the distance between the end faces of the pair of bent portions formed on the door frame, and The hook part pushes up the locking member, and the hook part and the locking member hold the pair of bent parts under pressure.

The present invention will be explained below based on embodiments shown in the drawings. What is shown in FIGS. 1 to 4 is a first embodiment of the present invention, and a door frame 1 is composed of an upper door frame 2 and a lower door frame 3 as shown in FIG. However, the door frame 1 according to the present invention is the upper door frame 2. The door frame has a pair of side plates 9 as shown in FIG.
, an upper template plate 6, a lower template plate 7, and a partition plate 4, each of which is fixed by spot welding, which is an example of welding, and has an H-shaped cross section and is divided into two by the partition plate 4. 2a and 2b are formed, and as shown in FIG. 3, an end portion 5a of the glass 5 for an openable door is inserted into the space 2b and fixed with an adhesive.

As shown in FIG. 4, a pair of bent portions 6 are formed in the upper part of the space 2a with the side plates 9 facing each other.
The distance C between the end surfaces 9a of the upper template 6 is larger than the distance A between the opposing bent end surfaces 6a of the upper template 6.

The elastic body 13 is formed of a plate spring (the plate spring may be made of steel or resin), and includes a pair of hook portions 13a and a pair of leg portions 13.
b and the support portion 13c are integrally formed so that the locking member 8 can be held therebetween.

The hook portion 13a is formed horizontally on the upper part of the elastic body 13, and its width B is larger than the distance A between the pair of bent end surfaces 6a and smaller than the distance C between the pair of bent end surfaces 9a. is formed.

The width D of the leg portion 13b is smaller than the distance A between the pair of bent end faces 6a, and the height H of the leg portion 13b is larger than the thickness of the upper template 6.

As shown in FIG. 3, a pair of hook parts 13a formed on the upper part of the elastic body 13 are suspended on the seat surface 6b of the upper template 6, and at this time, the upper surface 8b of the locking member 8 is attached to the door frame. Space part 2 formed in 2
By being inserted into the space 2a so as to be in contact with the upper surface 2f of the elastic body 13, the locking member 8 is pushed up by the support portion 13c of the elastic body 13, and the pair of hook portions 13a and the locking member lock the upper mold. Bent portion 6c of plate 6
A plurality of locking members 8 are accommodated in a space 2a formed in the door frame 2 while holding the locking members 8 under pressure.

As shown in FIG. 4, the door frame 2 is attached to the locking member by passing the mounting screw 16 inserted through the mounting hole 10a formed in the hanging member 10 through the washer 15 into the groove 2e formed in the door frame 2. The locking members 8 are configured to be attached to the hanging member 10 by screwing into the screw holes 8a of the door frame 2, and each of the locking members 8 independently moves inside the space 2a of the door frame 2 with an appropriate frictional force. It is constructed so that it can be moved around.

Function The present invention is constructed as described above, and its function will be explained below. The elastic body 13 can be formed by, for example, pressing a spring plate, cutting it out, and then bending it into the shape shown in FIG. 4, and the processing is very simple. When assembling the locking member 8 to the elastic body, it is sufficient to press the locking member into the elastic body 13 from the side with a light force.
This assembly work is also easy, and no welding is required. And the elastic body 1 integrated with the locking member 8
3 is inserted from the side of the door frame 2 as shown by arrow E in FIG. Note that a plurality of such elastic bodies 13 are attached to the door frame 2 as shown in FIG. As shown in the same figure, when the distance between the centers of the mounting holes 10a of the hanging member 10 is P ₁ , insert the tip of a screwdriver etc. into the screw hole 8a of the locking member 8, and insert the screw hole 8a of the locking member 8. The locking member 8 is fixed to the hanging member 10 by moving it directly below the mounting hole 10a, inserting the mounting screw 16 into the mounting hole 10a, and screwing it into the screw hole 8a of the locking member 8 through the washer 15. and door frame 2
is attached to the hanging member 10.

As shown by the imaginary line in FIG. 2, when the distance between the centers of the mounting holes of the hanging member 10 reaches P ₂ , the locking member 8 can be moved and fixed to the hanging member 10 by the same operation. Bye. In this way, the hanging member 10
Since the locking members 8 move independently in the space 2a of the door frame 2 even if the distance between the centers of the mounting holes 10a changes, there is no need to replace the locking members 8, and the door frame 2 can be easily replaced. It can be attached to the hanging member 10.

Furthermore, even if the door frame 2 is tilted during the installation work of the door frame 2, the locking member 8 is attached to the bent portion 6c of the upper template 6 of the door frame 2 via the elastic body 13.
Since the locking member 8 is held under pressure, it remains stationary without moving freely.
This facilitates installation work that requires zero fixation. Further, since the locking member 8 remains housed in the door frame 2 together with the elastic body 13, the same effect can be achieved even during disassembly and repair, which is convenient.

What is shown in FIG. 5 is a second embodiment of the present invention, in which an elastic body 13 closely contacts the upper surface 8b of the locking member 8.
A hook portion 13a is integrally formed at the top, and a mounting hole 13d through which a mounting screw 16 is inserted is formed in the center of the hook portion.

A pair of support parts 13c are formed at the lower part of the elastic body 13, and the locking member 8 is configured to be held in the elastic body 13 under pressure by the support parts. Further, since its operation is similar to that of the first embodiment, a description thereof will be omitted.

Effects Since the present invention is constructed and operates as described above, the width of the hook portion disposed on the elastic body is set to be larger than the distance between the end faces of the pair of bent portions formed on the door frame. The locking member is pushed up by the support part of the elastic body, and the bending part formed in the door frame is held by the hook part and the locking member. The number of components to be installed in the space formed in the space can be reduced by one compared to the conventional example, and at the same time, processing steps such as welding can be omitted, thereby reducing manufacturing costs. The following effect can be obtained.

In addition, the structure of the elastic body disposed to attach the locking member to the door frame can be greatly simplified, and the locking member can occupy a part of the space formed in the door frame, mainly the upper space. The effect is that it can be used for hanging members of various specifications regardless of the size of the space formed in the door frame.
