Description

[Detailed Description of the Invention] The present invention relates to a presser metal fitting that removably installs a cover plate on an inner frame that is attached to an outer frame so as to be openable and closable in a ceiling inspection opening.

The ceiling inspection port is installed in one section of the ceiling as an entrance and exit for maintenance, inspection, and repair of various piping and wiring inside the ceiling, and an example of the ceiling inspection port is shown in FIGS. 1 and 2.

In the figure, a rectangular inner frame B is disposed within a rectangular outer frame A suspended horizontally from a ceiling base material (an edge) not shown, with its lower edge aligned at the same height, and the outer frame A and the inner frame The two are connected by a rotation axis C provided biased to one side of B, and the inner frame B is rotatable about this rotation axis C.

Under normal conditions, the inner frame B is locked by an appropriate locking mechanism (not shown).
is attached to the outer frame A to close the doorway between the room and the inside of the ceiling, and when used for maintenance, inspection, repair, etc., the locking mechanism is released and the inner frame B is released as shown by the chain line in Figure 2 to open the doorway. It is something.

A mounting piece F for a ceiling board E is provided protruding outward from the lower edge of the outer frame A, and a ceiling board E is provided inward from the lower edge of the inner frame B.
A mounting piece H of the lid plate G made of the same material and pattern is provided in a protruding manner.

As described above, when the inner frame B rotates, the cover plate G is fixed to the mounting piece H in order to prevent the cover plate G from shifting or falling.

However, it is not desirable to integrally fix the cover plate G to the mounting piece H because the cover plate G will also be changed in the same way as the ceiling board ξE when changing the pattern or relining of the ceiling board E.

The present invention provides a holding fitting for a ceiling inspection port as described above, which presses and fixes the cover plate to the inner frame and makes it easy to attach, detach, and replace the cover plate.

One embodiment of the present invention will be described in detail below according to the drawings.
4, the reference numeral 1 indicates the main body of the presser fitting of the present invention, in which the strip-shaped metal plate is held horizontally, and the lower plate 2 is held in the horizontal direction.
is tilted upward and bent into a U-shape that expands completely,
The lower plate 2 and the upper plate 3 have locking pieces 4 and 5 bent outward in series on their leading edges, and a fixing piece 6 is provided on the lower plate 2 to protrude downward, and the presser foot The metal fitting body 1 has metallic elasticity.

The presser metal fitting of the present invention has the above-mentioned structure, and an example of its use will be explained with reference to FIG.

In the figure, the outer frame A, the inner frame B, the ceiling board E, and the cover plate G are the above-mentioned known ones, and after the cover plate G is placed on the mounting piece H of the inner frame B, the inner frame B and the cover plate G are Insert the locking piece 4 connected to the lower plate 2 between the end faces, place the lower plate 2 on the cover plate G, and then close the upper plate 3.
When the tip of the locking plate 5 is pushed down downward and the locking plate 5 is inserted into the locking groove B1 on the upper part of the inner frame B, the fixing piece 6 protruding from the lower plate 2 is driven into the cover plate G and attached to the inner frame B. Fix the cover plate G.

Similarly, the lid plate G is fixed to the inner frame B at several locations on two or four opposing sides of the inner frame B using the metal fitting main body 1.

According to the present invention described above, the lower plate 2 is made horizontal and the upper plate 3 is inclined upward by bending the rectangular metal plate into an expanded U-shape. is in contact with the cover plate G, and after the metal fitting body 1 is attached to the inner frame B, the lower plate 2 is pressed against the cover plate G by the elastic action of the U-shaped metal plate in the direction of expansion, and the cover plate G is moved to the mounting piece H. the fixing piece 6 of the lower plate 2 is pressed against the cover plate G.
The cover plate G is firmly fixed to the inner frame B by being driven in, and will not shift or fall off when the inner frame B is opened and closed.

In addition, since the latching pieces 4 and 5 of the lower plate 2 and the upper plate 3 are inserted between the end faces of the inner frame B and the cover plate G and into the latching groove B1 of the inner frame B, the problem that occurs when the frame B is opened and closed is avoided. The metal fitting body 1 stably fixes the lid plate G to the inner frame B without coming off from the inner frame B due to vibration.

When it becomes necessary to replace the cover plate G, all you have to do is remove the locking piece 5 of the upper plate 3 from the locking groove B1 of the inner frame B, and remove the lower plate 2 from the cover plate G. Exchanges can be made easily.

Claims (1)

[Scope of utility model registration request] The lower plate 2 is tilted horizontally and the upper plate 3 is tilted upward to form a rectangular metal plate bent into an expanded U-shape. This metal fitting for a ceiling inspection opening is characterized in that sealing pieces 4 and 5 are bent and arranged in series, and a fixing piece 6 is provided downwardly protruding from a lower plate 2.
