[Industrial applications]

 The present invention relates to a closing plate for a floor panel opening.

[0002]

[Prior Art]

 FIG. 9 shows a conventional example of a closing plate used to close an opening of a floor panel when an outlet or the like is not attached. In this conventional example, the closing plate A is formed into a substantially L-shaped cross section, and is used by being placed on the peripheral edge of the opening 3 of the floor panel 1.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, since the closing plate is only placed on the floor panel 1, it has a drawback that abnormal noise or rattling occurs during walking.

The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide a floor panel opening closing plate that can completely prevent rattling during walking. ..

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 6 shows the use state of the closing plate. First, the floor panel 1 is formed by joining the top panel 1a and the back panel 1b at the peripheral edge and filling the hollow portion with the inorganic filler 1c. This floor panel 1 is provided with a notch-shaped opening 3 at the center of the side edge thereof, and a flange 2 for fixing the closing plate is provided at the peripheral edge of the opening 3. A small hole 2a is bored in the flange 2 to receive a positioning projection 7 of a mounting portion 5 which will be described later to position the closing plate (see FIGS. 1 and 4).

As shown in FIG. 1 and below, the closing plate is a closing plate main body formed in an L-shaped cross section by hanging a hanging portion 4b from a front edge of a surface plate portion 4a closing the opening 3 of the floor panel 1. 4 is formed by covering the back surface and the peripheral edge of the mounting surface 5 with a mounting portion 5 made of synthetic resin.

The closing plate body 4 includes a locking claw 8 which is cut and raised rearward from a lower end edge of the hanging portion 4b, and an inclined portion 9 formed by bending a rear portion of a side edge of the front surface plate portion 4a in a downward slope. A locking projection 10 formed in front of the inclined portion 9, a U-shaped notch 11 provided at the center of the rear end edge, and an arc-shaped notch 12 provided on the side of the U-shaped notch 11. However, between the U-shaped notch 11 and the arcuate notch 12, a recessed groove 13 extending from the rear edge of the surface plate portion 4a to the upper portion of the hanging portion 4b is provided to improve rigidity.

On the other hand, the mounting portion 5 is provided with a face plate portion 5a corresponding to the surface plate portion 4a of the closing plate body 4 and a front wall 5b corresponding to the hanging portion 4b, and the face plate portion 5a and the front wall 5b have To prevent the side edges of the closing plate body 4 from being exposed to the outside, the central portion except the peripheral portion is provided with a main body receiving surface 14 which is recessed according to the outer shape of the closing plate body 4 by the thickness of the closing plate body 4. Be done. Further, the main body receiving surface 14 is lightened to include a portion corresponding to the concave groove 13 of the closing plate main body 4, and interference with the back surface of the concave groove 13 is prevented.

Further, the main body receiving surface 14 is provided with an inclined concave groove 15 corresponding to the inclined portion 9 of the closing plate main body 4, and the inclined concave groove 15 and the rear edge of the lightening portion 16 are provided. The pressing pieces 18 project from the upper ends of the edge portions 17 of the main body receiving surface 14 so as to project upward. A step portion 19 for locking the locking projection 10 of the closing plate body 4 is provided on the edging portion 17 of the main body receiving surface 14, and a locking claw 8 of the closing plate body 4 is provided on the front wall 5b. Is provided with a locking recess 20.

Thus, the closing plate body 4 is mounted on the mounting part 5 by sliding the surface plate part 4a rearward on the face plate part 5a, and in the mounted state, the inclined part 9 and the rear end of the concave groove 13 are mounted. Is pressed by the pressing piece 18, the locking claw 8 of the hanging portion 4b is locked by the locking recess 20 to prevent upward disengagement, and the locking projection 10 is locked by the stepped portion 19. By the way, detachment to the front edge side is prevented.

Further, the attachment portion 5 includes a wire opening forming portion 21 arranged corresponding to the U-shaped notch 11 of the closing plate body 4. A guide groove 22 is formed in the peripheral edge of the passage opening forming portion 21 so as to have a small thickness, and the passage opening can be easily opened by sandwiching the guide groove 22 with a tool such as pliers and easily punching. To be done.

On the other hand, on the back surface of the face plate portion 5a, a positioning projection 7 that matches the small hole 2a formed in the flange 2 of the floor panel 1, a locking leg 6, and a rearward rotation from the front wall 5b are formed. The reinforcing frame portion 23 is provided.

As shown in FIG. 4, the locking leg 6 has a joining side leg portion 6 a protruding from the back surface of the face plate portion 5 a and a cantilever beam extending upward from the lower end of the joining side leg portion 6 a. The elastic leg 6b is formed in a U-shape in cross section, and the elastic leg 6b is provided with a bulge 6c elastically locked to the flange 2 of the floor panel 1.

Therefore, in this embodiment, when the closing plate is pushed in from above the opening 3 of the floor panel 1, the elastic leg 6b of the locking leg 6 is elastically deformed, and the bulging portion 6c becomes the flange 2 of the floor panel 1. It is elastically locked to and the mounting work is completed. In this state, as shown in FIGS. 4 and 5, the mounting portion 5 is interposed between the peripheral edge of the closing plate body 4 and the back surface and the floor panel 1, so that the metal contacts of both are prevented. Be stopped.

Further, when removing the closing plate from this state, as shown in FIG. 7, the finger is inserted into the finger hooking concave portion 24 provided in the mounting portion 5 and pulled up. As a result, the closing plate pivots upward with the front edge as a fulcrum, and the locking state of the locking leg 6 to the floor panel 1 is released.

In this case, when the locking leg 6 is arranged at the center of the side edge portion of the mounting portion 5 as in this embodiment, the pulling force in the finger-holding recess 24 is caused by the lever action. In this case, since it acts as a large release force at the time, the blocking plate can be easily removed even if the locking force at the locking leg 6 is increased. As a result, the locking force of the locking leg 6 can be increased, and the rattling of the mounting can be effectively prevented.

Further, in the above description, the case where one passage opening forming portion 21 is provided is shown, but as shown in FIG. 8, two or more passage opening forming portions 2 are provided. It is also possible to provide 1.

[0021]

[Effect of the device]

 As is clear from the above description, the closing plate according to the present invention is mounted by elastically locking the locking legs protruding from the back surface of the synthetic resin mounting portion to the flange of the floor panel. Therefore, it is possible to reliably prevent looseness between the floor panel and the closing plate.

Further, since the mounting portion is provided so as to cover the peripheral edge and the back surface of the closing plate main body, the opening of the floor panel and the closing plate main body do not come into metal contact with each other, and abnormal noise is generated. Can be prevented.
