It consists of a mating body 6. Accordingly, the following description will be made focusing on these members 5 and 6 with reference to other drawings.
[0012]
First, the first fixed back plate 5 will be described. Reference numeral 15 denotes a hook-shaped fixing portion. A convex peripheral wall portion 18 constituting a part of the shaft hole 17 is continuously formed at the center portion of the outer wall surface 16 of the hook-shaped fixing portion 15. Further, a plurality of (four in total) through holes 19 for the fixing tool 8 are formed in the flange-shaped fixing portion 15 at a predetermined interval in the radial direction. Furthermore, a plurality (four in total) of engagement notches 21 are formed at predetermined intervals on the outer wall side peripheral surface 20 that intersects the outer wall surface 16 of the hook-shaped fixing portion 15. These engagement notches 21 are located diagonally to each other and, as shown in FIG. 3 or FIG. 6, reach the inner wall surface 22 of the hook-shaped fixing portion 15 from a portion near the outer wall surface 16 of the outer wall side peripheral surface 20. It is formed to be slightly smaller.
[0013]
By the way, as shown in FIG. 3, the protruding peripheral wall portion 18 has a projecting upper end portion formed in a stepped shape. Therefore, the convex peripheral wall portion 18 includes a large-diameter support portion 18a that is annularly connected from the outer wall surface 16 of the hook-shaped fixing portion 15 and a small-diameter fitting portion that is annularly continuous with the large-diameter support portion 18a. 18b can be distinguished.
[0014]
Here, the fitting relationship between the convex peripheral wall portion 18 of the first fixed back plate 5 and a first fitting seat body 6 to be described later will be explained. The portion 18a is in surface contact (contact) with the inner surface of the inner peripheral edge portion 30a that forms the fitting hole 31 of the first fitting seat body 6. On the other hand, the small-diameter fitting portion 18b is just inserted into the fitting hole 31 of the first fitting seat body 6.
[0015]
Thus, reference numeral 25 denotes a notch portion for inserting the leading end portion of the extraction tool 26 formed in the convex peripheral wall portion 18 with a required interval (hereinafter referred to as “notch portion for extraction tool”). It is. Here, the “pulling tool 26” refers to a screwdriver or a tool that can be operated by hand as shown in FIG.
[0016]
In the present embodiment, the notch portion 25 for the extraction tool includes a single engagement notch portion 21 with which an engagement protrusion 34 described later of the first fitting seat body 6 is engaged, and the one engagement notch portion 21. The first fitting seat body 6 can be easily pulled out by appropriately forming it on a portion of the convex peripheral wall portion 18 positioned on a straight line connecting the other engagement notch portion 21 to be provided. Therefore, the drawing tool notch 25 should be formed in consideration of the number of the engaging protrusions 34 of the first fitting seat body 6 and the number of the engaging notches 21 of the first fitting seat body 6. Each extraction tool notch 25 is formed from the upper end surface of the small-diameter fitting portion 18b to the outer wall surface 16 of the bowl-shaped fixing portion 15 with reference to FIG. To facilitate the insertion.
[0017]
Next, the first fitting seat body 6 will be described. The first fitting seat body 6 is made of, for example, aluminum that can be displaced somewhat. The first fitting seat body 6 will be described with reference to FIGS. 4 and 5. Reference numeral 30 denotes a planar annular portion, and a convex peripheral wall portion of the first fixed back plate 5 is provided at the central portion of the planar annular portion 30. A fitting hole 31 to be fitted to 18 is formed. Reference numeral 32 denotes a peripheral wall-shaped skirt portion that covers the outer wall-side peripheral surface 20 of the first fixed back plate 5. The inner peripheral wall surface 33 of the peripheral wall-shaped skirt portion 32 is engaged with the engagement notch portion 21 described above. The engaging projections 34 are provided with a required interval (in the present embodiment, as opposed to each other).
[0018]
In the above configuration, when the first fitting seat body 6 is fitted to the first fixed back plate 5 as shown in FIG. 8, the positions of the engagement protrusions 34 and the engagement notches 21 are visually aligned. While pressing the first fitting seat body 6 against the first fixed back plate 5.
[0019]
As a result, the small-diameter fitting portion 18b of the convex peripheral wall portion 18 of the first fixed back plate 5 is fitted into the fitting hole 31 of the first fitting seat body 6, and at the same time, the inner peripheral edge portion 30a of the planar annular portion 30 is fitted. It abuts on the upper surface of the large-diameter support portion 18a of the first fixed back plate 5. At this time, the engaging protrusion 34 that has moved over while sliding a part of the outer wall side peripheral surface 20 (the edge on the outer wall surface 16 side) of the first fixed back plate 5 is fixedly engaged with the engaging notch 21. . Further, some space 36 remains between the outer wall surface 16 of the first fixed back plate 5 and the inner surface of the planar annular portion 30 of the first fitting seat body 6. As a result, the first fitting seat main body 6 is in a locked state with the first fixed back plate 5. For example, the first fitting seat body 6 cannot be removed from the locked state by hand from the first fixed back plate 5. The engaging tip 27 can be inserted into the extraction tool cutout 25 or into the space 36 via the extraction tool cutout 25.
[0020]
Therefore, if it is desired to remove the first fitting seat main body 6 from the first fixed back plate 5 now for the necessity of repair, first, as shown in FIG. Put in. At this time, the pair of left and right tip portions 27 are directed toward the notch portion 25 for the extraction tool. Therefore, when the extraction tool 26 is an ordinary driver, its tip is inserted into one extraction tool notch 25. Next, as shown in FIG. 10, the leading end portion 27 of the extraction tool 26 is inserted into the inner wall surface side of the inner peripheral edge portion 30 a of the planar annular portion 30 or the space 36 through the notch portion 25 for the extraction tool. Then, when the extraction tool 26 is pulled (in the case of a driver, when the extraction tool 26 is pulled out), the first fitting seat body 6 comes out of the first fixed back plate 5.
[0021]
The pulling tool 26 is preferably of a type in which a pair of left and right end portions 27 are always opened outward by the spring force of the material itself.
[0022]
【Example】
Here, the main points of the design change of the first embodiment of the present invention from the standpoint of those skilled in the art will be pointed out.
(1) First, the drawing tool notch portions 25 may be provided corresponding to the number (for example, four) of the engagement notch portions 21.
(2) Next, the size of the notch 25 for the extraction tool should be slightly wider in the circumferential direction considering that the extraction tool 26 is a driver.
(3) Since the convex peripheral wall portion 18 is divided into a large-diameter support portion 18a and a small-diameter fitting portion 18b, when the first fitting seat body 6 is fitted to the first fixed back plate 5, Although some internal space 36 is formed between the members 5 and 6, it is not a specific requirement of the invention to form the convex peripheral wall portion 18 in such a stepped shape. This is because, for example, the internal space 36 is generated even when the head of the fixing tool 8 slightly protrudes from the planar annular portion 3. Moreover, it is because the 1st fitting seat main body 6 can be removed from the 1st fixed back board 5 even if it uses only the notch part 25 for extraction tools. Therefore, one or two or more extraction tool notches 25 are formed on the convex peripheral wall 18 so that the leading end 27 of the extraction tool 26 can enter the axial hole 17 from the upper (outer) end surface thereof. It only has to be done.
[0023]
【The invention's effect】
As is apparent from the above description, in the present invention, the edge portion of the first fitting seat main body is not easily deformed even if a drawing tool such as a screwdriver is used. In addition, careless damage to the inner wall surface of the door does not occur. And a 1st fitting seat main body can be easily removed from a 1st fixed backplate.
