よって決めることができる。According to this embodiment, when the projections 2a and 2b of the connecting member 2 are fitted into the recesses 8 of the member 1 to be connected,
Since the tops of the protrusions 12 and 14 are pressed against the facing surfaces, and the connecting member 2 is made of a material softer than the connected member 1 at this time, the protrusions 12 crush the tops of the protrusions 14,
This allows a tight bond. Therefore, the connecting member 2 is easily fitted to the connected member 1 and is unlikely to come off, and it is possible to absorb a dimensional error. The degree of difficulty in removal can be determined by the amount of fitting of the convex portions 2a and 2b into the concave portion 8.

易になる。Further, since the pin 40 is fitted in the tubular portion 37,
The connecting member 2 becomes more difficult to come off from the connected member 1. In this case, since the ridge 38 is formed on the oval cylindrical portion 37, the pin 40 can be fitted between the ridges 38, so that the dimensional variation can be absorbed and the fitting of the joint can be performed. It is possible to absorb variations in degree. Furthermore, since the connecting member 2 is made of plastic, which is a softer material than the connected member 1, the connecting member 2 can be easily manufactured.

That is, this connecting structure is applied to a frame such as a window frame, and both the connected member 1 and the connecting member 2 are made of aluminum having the same hardness. The end portion of the concave portion 8
A large number of projections 12 having a mountain-shaped cross-section whose corners are angled are formed in the width direction so as to form a streak in the longitudinal direction of the connected member 1, and a pin insertion penetrating the recess 8 is formed on the inner surface of the recess 8 facing one another. The hole 43 is formed on one side surface of the concave portion 8 in the other facing direction and, for example, four connected members 1a 'shown in FIG.
The end faces of the respective connected members 1 are obliquely inclined at about 45 degrees so that the rectangular frames can be formed by connecting ~ 1d '. The connected member 1 is extruded in the longitudinal direction.

A plurality of pin-holding pieces 41a, 41b for pin-pinning are provided at a position aligned with the pin insertion hole 43 on the inner surface of the pin 5.
Then, a large number of protrusions 14 having a chevron-shaped cross section, which extend in the width direction so as to intersect the protrusions 12 and intersect the protrusions 12 and whose apex is a corner, are formed on the outer surface of the connecting member 2 in the longitudinal direction of the protrusions 2a and 2b. are doing. A protrusion 14 'having the same shape as this protrusion 14
Is also formed on the opposing surfaces of the sandwiching pieces 41a and 41b. Such an L-shaped hollow cylindrical connecting member 2 can be formed by extrusion molding as shown in phantom in FIG. 5 and then cutting it into a predetermined width. The pins 42 are made of aluminum nails or rivets, and are hammered through the pin insertion holes 43 between the sandwiching pieces 41a or 41b to ensure the fixation of the coupling member 2 fitted to the coupled member 1. There is.

There is a tight bond. In addition, between the pair of holding pieces 41a arranged in the extending direction of the convex portions 2a and 2b and between the convex portions 2a and 2b.
By sandwiching the pin 42 between a pair of sandwiching pieces 41b arranged in a direction perpendicular to the extending direction of the pin, when the pin 42 is sandwiched between the sandwiching pieces 41a, it is possible to prevent the pin from completely coming off.
When it is fitted between them, the retaining effect by frictional locking is great, but it can be pulled out. Therefore, it has an effect equal to or higher than that of the first embodiment.

There is a possibility that it will move about 2 mm and a gap will be created at the corners of the connected members 1a'-1d 'shown in FIG. In this case, after aligning the four corners of the connected members 1a 'to 1d', the pin 42 is made to approach the corner side of the pin insertion hole 43, that is, the inner side of the sandwiching piece 41b (solid line in FIG. 6). A 2 mm movement can be regulated by tapping. Therefore, the diameter of the pin insertion hole 43 can be increased to facilitate the insertion of the pin 42.

As another embodiment, the protrusions 12 and 14 may have a mountain shape in which only the top portion 12b is a curved surface as shown in FIG. 10, or the top portion 12b is a corner as shown in FIG. 11, but has a large inclination. Yamagata etc. may be used. 12a shows an example of the position of the top portion 12b when the top portion 12b is crushed. That is, in this case, the crushing increases the frictional locking force, but at the same time, it also absorbs the dimensional variation and the variation in the fitting amount by the dimension h. Although the protrusions 12 and 14 extend in a streak shape, they may have a conical shape or a pyramid shape in a plan view, and these may be scattered or arranged in a predetermined shape in a plan view such as letters or symbols. Good.

る。According to the connecting structure of the first aspect, when the convex portion of the connecting member is fitted in the concave portion of the member to be connected, the top of the protrusion is pressed against the facing surface, so that the protrusion is formed on only one side. If the top of the protrusion bites into the opposing surface or is crushed by the opposing surface, if the protrusions are formed on both sides, the tops of the protrusions crush each other or one protrusion crushes the other protrusion, By these, it is possible to tightly bond. Therefore, the connecting member is easily fitted to the member to be connected and is unlikely to come off, and it is possible to absorb a dimensional error.

In addition to the effect of the second aspect, manufacturing of the connecting member is facilitated.
According to the connecting structure of the fourth aspect, in addition to the effect of the first aspect, since the pin is fitted in the tubular portion, the fitting between the connecting member and the connected member becomes more difficult to come off.
