Description

[Detailed Description of the Invention] This invention relates to a fixing device for press-locking a panel such as a metal mirror plate to a frame material forming a fitting such as a door.

Conventionally, when manufacturing a highly decorative door by incorporating a panel such as a metal mirror panel into a space created by forming a frame, a door as shown in Figure 1 is used to prevent the panel from swinging and making noise. The peripheral edge of panel C is in contact with the synthetic resin cushion material housed in the groove of frame material B, and during assembly, panel C is pushed against frame material body B against the elastic force of the cushion material. Since the assembly was pushed into the groove, the work was not only difficult, but also because there was no cushioning material between the panel and the groove opening, it was difficult to shake the panel body in the indoor/outdoor direction (arrow x direction) after assembly. It was not possible to completely prevent the movement.

In addition, in the frame mounting structure of Utility Model Application Publication No. 52-97842,
It is disclosed that a picture frame is attached using a rim, and this rim has two leg pieces protruding from a prospective wall to form a substantially U-shaped cross section, and a hook-shaped rim provided at the tip of the leg piece. The engaging piece is fitted and locked into the engaging part provided on the frame material, but when the edge is attached, the protruding piece protruding from the tip of the prospective wall is attached to the protruding part provided on the outer periphery of the frame. Since the projections of the picture frame only touch each other, there is a problem in that the picture frame becomes unstable if there are variations in the projected dimensions of the protruding parts of the picture frame or variations in the projected dimensions of the rim. Since there is a gap between the ridges, a compaction material is required to fill this gap. Therefore, there is a problem that the number of parts increases, leading to high costs, or that the installation becomes complicated.

This invention improves the drawbacks of the conventional ones mentioned above, and not only simplifies the assembly work of the panel, but also allows the cushioning action to work in the vertical direction, horizontal direction, and indoor/outdoor direction toward the front of the panel. , can reliably prevent the panel from swinging,
Moreover, the present invention provides a device that eliminates the need for cushioning material and compaction material that were conventionally provided around the panel.

The structure of this invention will be explained in detail with reference to the embodiment shown in FIGS.
A locking wall 10a is erected and a groove 12 is formed. Then, the above-mentioned rising wall 10 and the locking wall 1
Locking recesses 11, 11 are formed on the respective inner surfaces of Oa.

The reference numeral 1 is a band-shaped fixing device made of a material such as synthetic resin or hard rubber, and has a certain degree of elasticity.
The frame member 8 has two recessed grooves 3, 3 facing in opposite directions on both sides, and the end of the frame member abutting wall 4 on one side has a protruding pressing part 5a that is inclined relative to the support part so as to fall outward, and the end of the pressing part forms an arc-shaped protrusion 6. A locking part 5b hangs down from the lateral wall 4a on the opposite side, and a locking recess 1 formed on the inner surface of the locking wall 10a of the frame member 8 near its base end.
A locking projection 7 for locking with the locking member 1 is provided.

Note that the shape of the bulging protrusion 6 is not limited to an arc shape, as long as it can come into contact with the locking protrusion on the edge of the panel and push it up without difficulty. Also, regarding the locking protrusion 7,
The present invention is not limited to this, and it is only necessary that the fixture 1 and the locking wall 10a lock together. For example, a locking recess 11 in which the locking protrusion 7 is provided in the locking wall 10a may be provided in the protruding locking portion 5b.

Reference numeral 13 denotes a cast panel used as a mirror plate of a door, with a protrusion 15 protruding from its edge;
Both sides of the protrusion have locking protrusions 14, 14a, which are provided over the entire periphery of the rectangular panel. Panel 1
3, the frame material 8 takes in the periphery of the panel, and the four circumferences of the panel are held down with fixing tools. In this case, the frame material 8 and panel 13 located below
Explain the relationship between

First, the locking projecting portion 14a of the panel 13 is brought into contact with and supported on the rising wall 10. Next, the fixture 1 is inserted between the protrusion 15 of the panel and the locking wall 10a. part 15 and locking wall 1
Insert the fixture 1 diagonally so that it contacts the prospective surface 9 between the panel 13 and the panel 13.
When the fixing tool 1 is pressed against the protrusion 15 and rotated so as to push down the locking part 5b using the joint corner as a fulcrum, the inclined pressing part 5a presses against the protrusion 15.
When pushed, it becomes upright and elastically deforms inward, and the elastic force causes the protrusion 15 of the panel 13 to
is pressed to press the protrusion 15 to the rising wall 10. At the same time, the protrusion 6 at the tip engages and presses against the lower side of the locking protrusion 14 of the panel 13 to support it. Then, when the other locking portion 5b is pushed down and inserted so that its tip is in sliding contact with the inner surface of the locking wall 10a of the frame member 8, the locking protrusion 7 formed near the base end of the locking portion 5b is inserted into the locking recess. 11, fixing tool 1
The locking wall 10a of the frame member 8 and the protrusion 15 of the panel 13
Due to its elasticity, it is tightly fitted between the two. As a result, the protrusion 15 is connected to the pressing portion 5a and the rising wall 10.
The panel 13 is clamped and held between the fixtures 1 and 1.
The panel mounting groove 16 is fixedly fixed in the panel mounting groove 16 formed by the upright wall 10 and the panel projecting portions 14, 14a are supported by the pressing portion 5a.

As explained above, this invention eliminates the need for conventional cushioning material because the locking protrusion of the panel is supported by the pressing part of the panel fixture, and the pressing part of the fixture has elasticity. The panel presses the projecting part of the panel against the side surface of the rising wall of the frame material, and the projecting part is clamped and held between the pressing part and the rising wall. It reliably absorbs dimensional variations and allows the panel to be tightly fixed without swinging. Further, since the tip of the pressing portion is engaged and pressed against the lower side of the panel overhang, the fixture will not be unnecessarily separated from the frame member.

In addition, when fixing a panel, the protrusion of the panel is brought into contact with the rising wall of the frame material in advance, and the fixing device is fitted between the protrusion of the panel and the locking wall of the frame material, which is different from conventional methods. When connecting the frame materials, there is no need for the complicated and forceful work of pressing the panel and cushion material together, making it easy to connect the frame materials. Since it is supported at the tip of the pressing part of the fixture, it has the excellent effect of not requiring a consolidation material to close the gap at the boundary between the locking projection and the pressing part.
