Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an assembled structure in which another plate or the like is attached and fixed to a main body having an integral frame structure by engaging a locking tool from the outside of the main body through a flexible member. It is.

Conventionally, in the case of large rearview mirrors used in relatively large vehicles such as freight cars and passenger cars, it is well known that when attaching the mirror plate to the frame, the mirror plate is curved to match the curvature of the mirror. Since we have adopted a structure in which the frames are assembled into one piece, even if the external dimensions are almost constant, if the sharp curvature differs or if the frame is flat, we can manufacture the frame in a shape that matches each case. Therefore, even if it is a mass-produced product, many types of molds, etc. are required, and the assembly structure is complex, so if you try to reduce the number of parts, it will become structurally impossible or unstable. It will be accompanied by

Such structural problems are often found not only in rearview mirrors but also in products in other fields.

The present invention solves such problems and provides a locking mechanism that can be mass-produced and can correspond to the required assembly structure by arranging the assembly locking means of the dependent part at any position as needed for attachment to the main body. It is an object of the present invention to provide an assembly structure provided with means.

A synthetic resin frame body is fitted around and engaged with the flexible frame body, and the flexible frame body has grooves for locking continuously formed on the outer periphery, and the grooves of the synthetic resin frame Penetrate each through hole from the outside of the main body,
A locking piece having a locking leg whose tip is formed to engage with a groove of the flexible frame, and a locking piece formed so that the upper seat plate covers the through hole is attached to the locking leg of the flexible frame. The locking legs are fitted into the locking grooves and fixed together.

In addition, in the present invention, the locking portion of the locking piece has a structure that has elasticity in either the longitudinal direction or the short side direction, or both directions, so that the locking portion of the locking piece has a structure that has elasticity in either the longitudinal direction or the short side direction, or in both directions. The structure is such that the locking portion contracts when inserted and returns to its original state after being inserted into the groove of the frame, increasing the locking force.

Further, in the present invention, the locking piece serving as the locking means can be disassembled into a plurality of pieces, and when assembled, the pieces can be assembled in sequence to self-lock and increase the locking force.

Further, in the present invention, various shapes or arbitrary patterns are formed on the outer projecting surface of the locking piece, which is a flexible frame locking means for integrally connecting the main body and the target mounting body, This locking piece was designed to serve as a decoration and also have an aesthetic effect.

By determining the position and drilling, it is possible to easily manufacture two types of rearview mirrors, a curved type and a flat type, using the same frame in the same manner as described above.

(See Figure 7) In short, if only the drilling of the through holes for inserting the locking pieces to fix the mirror plate is done according to the required model, the main frame can be manufactured using a type of press mold. This increases economic efficiency.

In addition, even if the mirror plate 6 is damaged, the locking piece 20 can be removed by inserting a thin metal piece or the tip of a screwdriver between the seat plate 23 and the outer surface of the frame 1, and lifting the locking piece 20. Since it can be easily disassembled by removing it from the locking groove 11 of the body, it also has the convenience of being able to be replaced with a new one and installed at will.

Furthermore, in the specific example described above, the flexible frame 10 for attaching the mirror plate 6 to the frame 1 is positioned such that a step 1'' is formed at the joint between the peripheral edge 1' of the frame 1 and the back plate 2. As explained above, without providing this step, the peripheral edge 1' of the frame 1 is connected to the back plate 2 as shown in FIG. A flexible frame 1 with a through hole 3 and engaged with the periphery of a mirror plate 6
By aligning the locking grooves 11 of 0 and locking the flexible frame 10 with the locking pieces 20 through the transparent holes 3 in the same manner as in the above specific example, the flexible frame body 10 can be fixed without intervening the stepped portion. This makes it possible to simplify the frame structure and reduce costs.

The above has described a specific example of a rearview mirror for a car, but for example, the mounting of a glass plate, decorative panel, etc. on metal furniture with a similar frame-shaped structure is a part, or the mounting of a light fixture is a part, or an article made of synthetic resin is used. Fitting attachment can also be used as a means of fixing parts.

Next, when attaching the object to the frame, the locking piece 20 as a fixing means has the shape of the locking leg 21 not only in the shape shown in FIGS. 4 and 5 but also in the arrow shape as shown in FIG. 21a, or a circular shape 21b as shown in FIG.
