-There is a publication No. 9351. To explain this with reference to the attached drawings, a bearing piece 4 with a bearing hole 12 is fixed to a U-shaped guide rail 2 with an inward expansion via a backing plate piece 6 in the rail 2 with screws, and the fixed position side Folding door 1
A pivot 15 protruding from the end of A is fitted into a bearing hole 12 of a bearing piece 4 and pivotally supported.

[Problem that the invention attempts to solve]

However, in the conventional structure, the bearing hole 12 is simply bored in the outer surface of the bearing piece 4. Therefore, when assembling the lower pivot 15 of the upper and lower pivots 14 and 15 protruding from the fixed-position side folding door 1A to the lower bearing piece 4 later, the bearing hole 12 cannot be directly seen, and the larger folding door It takes a lot of effort to assemble, as it requires supporting and searching for the fit. If this search fit takes time, it will damage the pivot and the bearing hole 12. . In particular, the higher the fitting precision between the pivot and the bearing hole 12, the more troublesome it is to assemble and the more likely it is to cause damage.

The purpose of this invention is to make a simple modification to the bearing piece 4 so that the pivot can be quickly and smoothly inserted into the bearing hole 12 when assembling the folding door.

[Means for solving the problem] The present invention has a bearing hole 1 formed in a stepped manner on the outer surface of the bearing piece 4 attached to the guide rail 2, as shown in FIG.
2, and a pivot guide groove 13 is provided on the outer surface of the bearing piece 4 extending from the bearing hole 12 to the outer edge of the bearing piece, and the guide groove 13 is formed in an outwardly expanding shape that becomes narrower toward the bearing hole 12 side. And the guide groove 13
The bottom surface of the groove at the rear end is configured to be substantially flush with the mouth edge of the bearing hole 12, and the groove width at the rear end is set to be approximately the same as the diameter of the bearing hole 12.

In reality, the bearing piece 4 having the above-mentioned configuration only needs to be attached to one of the upper and lower rails 2, in most cases, the lower rail 2. Because the upper pivot 1
4 can simply be guided and fitted into the bearing hole 12 of the conventional bearing piece 4 provided on the upper rail 2 from below.

[Effect]

In such a case, when assembling the folding door to the guide rail 2, simply insert the pivot on the folding door side into the wide entrance part of the pivot guide groove 13 of the bearing piece 4 previously attached to the rail 2, and push it inwards. Then, the pivot is correctly guided to the edge of the bearing hole 12 by the guide groove 13, and is inserted into the bearing hole 12 as it is.

[Effect of idea]

Therefore, according to the present invention, the pivot can be correctly fitted into the bearing hole 12 simply by roughly positioning the pivot in the wide entrance of the pivot guide groove 13 formed on the outer surface of the bearing piece 4 and pushing the pivot. To easily and quickly assemble and pivot a folding door without the trouble of searching and fitting.

Further, since there is no need to perform search fitting, it is possible to prevent problems such as improperly moving the folding door and forcing the pivot into the bearing hole 12, thereby causing damage.

It is guided and engaged so that it can slide freely along.

The present invention is characterized by the bearing structure of the one end pivoting connection part of the fixed position folding door 1A. FIG. 2 shows the upper pivot connection A, and FIG. 3 shows the lower pivot connection B.

The guide rail 2 has a U-shaped cross section, and the left and right outward edges 2a, 2a of the opening thereof
The entire structure, except for , is buried in Structure 3. There are protrusions 2 on the left and right on the inner surface of the guide rail 2 near the opening.
b and 2b are formed in a protruding manner to face each other, and the cross-sectional shape as a whole exhibits an inwardly expanding U-shape.

A bearing piece 4 common to the upper and lower pivot joints A and B is attached to the guide rail 2. This bearing piece 4
is made of synthetic resin material (e.g. 6 nylon),
It is formed in a roughly T-shaped cross-sectional shape so that it can be inserted into the guide rail 2 from the side end, and the grooves 5, 5 formed on the left and right side surfaces of the guide rail 2 are fitted into the protrusions 2b, 2b. This prevents it from coming off in the vertical direction.

A backing plate piece 6 is attached to the back of the bearing piece 4 only from the lateral side.
A recessed space 7 is formed into which a screw can be inserted, and a screw 9 installed through a screw insertion hole 8 formed on the outer surface of the bearing piece 4 is screwed into a screw hole 10 of the backing plate piece 6.
As shown in FIGS. 4 and 5, the bearing piece 4 can be fixed at a desired position on the guide rail 2 by tightening the contact plate piece 6 while abutting it on the inside of the protrusions 2b, 2b.
