In this manner, unlike the prior art, the distal end of the crosspiece B is formed with a plurality of screw holes at the connecting portions of the studs, and the connecting block 70 of the crosspiece is screwed to the stud. Without any troublesome and time-consuming screwing work,
With a one-touch fitting operation, the studs A are extremely easily, quickly, and reliably connected in a T-shape butted connection position. Therefore, as shown in FIG. 15, the work of assembling the lattice unit 60 between the studs A, A is performed as described above in each of the connecting long holes 1 provided at a total of four locations of the two studs A, A. After the fitting connecting tool 100 is fitted, the upper and lower horizontal rails B, B (62, 63 in FIG.
Can be completed at once by simply fitting the respective ends of the respective fittings into the main body 3 of the respective fitting-type couplers 100 from above. Then, the decorative cover C is pushed from between the side walls from above the horizontal rail B, and the locking claws d, d are engaged with the locking claws c, c on both upper ends of the horizontal rail B. Each fitting protrusion 5 protruding from the upper surface of the bar B is covered and covered by a decorative cover C.

FIGS. 12 to 14 show another embodiment of the present invention. The difference from the above-described embodiment is that, as shown in FIG. 14, a cross bar B1 having a shape such that the cross bar B and the decorative cover C of the above embodiment are integrated is used. Therefore,
Compared with the above embodiment, the number of parts required for assembling the handrail and the number of assembling steps are reduced, and the installation cost of the handrail can be reduced accordingly.

The fitting of the present invention is not limited to assembling aluminum handrails, but can use two extruded materials (corresponding to studs A and cross bars B) having various cross-sectional shapes. It can be effectively used for the purpose of butt connection in a T-shape without using any screws. In this case, the shape and the like of the main body 3 may be appropriately changed according to the shape of the extruded material. The object of the present invention can be achieved even if the structure of the details is changed as appropriate, for example, the connecting long hole 1 is not limited to an elliptical shape but may be formed in a rectangular shape.

[0016]

As is apparent from the above description, the fitting type fitting for an extruded material according to the present invention has excellent practical effects as listed below. (A) Conventionally, a plurality of connecting screws, which are required for each connecting portion, are no longer required. (B) Therefore, the operation of drilling a large number of screw holes and bolt holes, which is inefficient and extremely troublesome, and the screwing operation can be completely eliminated. (C) Further, the labor and cost for purchasing and storing screws and transporting them to the work site are not required. (D) Since the connection work only requires a very simple fitting, even an unskilled person can perform the connection very quickly and reliably. (E) Therefore, unlike the related art, there is no inconvenience that a predetermined connection strength cannot be obtained due to forgetting screwing of a part or uncertainty of screwing.
