Description

[Detailed description of the invention] (Industrial field of application) The present invention is a folding stack that is suitably used as a rain door, etc., and is particularly designed to be used in parallel between upper and lower rails that extend in the left-right direction and face each other in the vertical direction. A pair of left and right folding stacks, which are formed by pivotally connecting a plurality of doors so that they overlap in the thickness direction so that they can be folded freely, are arranged to face each other in the left-right direction, and the opposite side is one end of both folding stacks. Vertical bars are fixed to each end, and each vertical bar is supported by the upper and lower rails via a center pivot so that they can rotate horizontally and slide freely in the left and right directions, and the other end of each folded pile is fixed to the upper and lower rails via a center pivot. The rail is horizontally rotatably supported on the left and right ends of the rail via the base pivot, and each folded pile extends in the left and right direction, and both vertical bars collide at the abutment surface that is the opposite end face of the heron. This invention relates to a folding stack that is configured to be openable and closable between a fully closed state and a fully open state in which each folding stack is folded.

(Conventional technology) Recently, various types of folding shutters have been developed.

For example, upper and lower rails each having a rail groove on the opposing surface 1 are arranged in parallel, a pivot receiver is provided at least at one end of both rails, and the upper pivot receiver is used to accommodate the folding weight. The hanging base pivot is rotatably mounted, and the center pivot of the folding stack is slidably inserted into the rail grooves of both rails. They are foldably connected through the intermediary.

(Problem that the invention aims to solve) However, in the conventional folding voice receiving system, no improvements have been made to the abutting surfaces of the pair of left and right folding voices. Since the abutting portions are simply opened and abutted, there is a drawback that rainwater easily enters and light easily leaks from the abutting portions.

As a means to eliminate such defects, for example, one abutting surface may be provided with a concave groove, and the other abutting surface may be provided with a protrusion that fits into the concave groove. Unlike sliding doors, etc., they approach each other while rotating and eventually butt against each other, so if the shape of the groove or protrusion is carelessly determined, they may not fit well or may not fit properly. However, there is a problem in that it is necessary to provide a large gap between the inner surface of the groove and the outer surface of the protrusion, and that wind and rain may blow in.

In addition, generally in storm doors, etc., a rising surface on the rear side of the rail groove is formed along the back surface of the door, and on this rising surface, rain and wind are allowed to pass through the gap created between the rail and the upper and lower sides of the door. Prevents it from blowing in.

However, since the abutting surface of the center pivot mounting part in this type of voice reception moves on the rail while rotating around the pivot toward the rising surface, the cross-sectional shape of the abutting surface may have an inappropriate shape, e.g. If the door has a rectangular cross section or a tall protruding ridge, the distance between the rising surface and the rear surface of the door should be increased to prevent the abutting surface from colliding with the rising surface. This makes it difficult to prevent wind and rain from entering on the rising surface.

The present invention aims to solve all of the above-mentioned problems in conventional voice reception.

(Means for Solving the Problems) The folding voice receiver of the present invention has a horizontal cross section of the abutment surface of one of the vertical bars fixedly installed at the opposing ends of the double folding voice receiver, which is approximately semicircular in horizontal section. The abutting surface of the other vertical bar is formed into a convex surface having a substantially semicircular horizontal cross section, and the abutting surface of the one vertical bar is formed into a convex surface having a substantially semicircular horizontal cross section, and the apex thereof is cut out. It is formed into a concave surface with a generally arcuate horizontal cross section into which the top of the plate can fit.

Note that a notch 10' corresponding to the center pivot insertion notch 10 is also provided on the front surface of both ends of the upper rail 2, and a closing member 25' having a symmetrical shape to the closing member 25 is attached to this notch 10'. Of course, it is.

Reference numeral 26 denotes a synthetic resin catch seat fitted onto the outer periphery of the lower fan surface pivot 8.

The catch seat 26 has a stepped cylindrical shape in which the upper half has a larger diameter than the opening width of the rail groove 3a, and the outer diameter of the lower half corresponds to the opening width. It is interposed between the lower surface of the voice receivers 6, 7 and the upper surface of the lower rail 3 to receive the weight of the voice receivers 6, 7, and the small diameter portion is inserted into the rail groove 3a and provided at the opening of the pivot receiving hole 5a. It is designed to fit into the counterbore hole 5a'.

In the above embodiment, the case where the radius of curvature of the concave surface is made slightly larger than the radius of curvature of the convex surface has been described, but the present invention is not necessarily limited to this.

However, by doing as described above, the concave surface and the convex surface are less likely to interfere with each other, so there is an advantage that the butt gap at the final stage can be made extremely small.

Furthermore, it goes without saying that the number of doors to be connected when forming left and right voice receptions is not limited to two.

Furthermore, the present invention can be applied not only to shutters but also to various other things such as garages.

In addition, the upper rail also has a notch for inserting the fan surface pivot,
Of course, the pivot receiver provided on the upper rail may have a shape symmetrical to that of the lower rail.

(Effect of the invention) The voice folding receiver of the present invention is constructed as described above, and in the fully closed state, the vertical bar at the right end of the left voice folding receiver and the left end of the right voice folding receiver are The vertical bars of the section are in a state where the top of the convex surface forming the abutting surface of one of the vertical bars is fitted into the concave surface formed with a notch in the top of the convex abutting surface of the other vertical bar, Since they are abutted against each other, there is no gap between the abutting surfaces of both vertical bars that can pass through in the front and back direction, which effectively prevents rainwater from entering or light leaking from both abutting surfaces. This can be prevented.

In addition, in the fully closed state, the abutment points of both abutting surfaces that are visible from the outside, that is, the both ends of the concave surfaces, are located at a position further back from the front and rear surfaces of both vertical bars.
The meeting point of both vertical bars does not give a strong impression of being a divided point, and the left and right folding receivers give the impression as if they were made up of a single door, which can produce an excellent design effect. It is.

Moreover, because the abutting points of both vertical bars are located in a recessed position, the surfaces of the vertical bars are painted, and the paint on the abutting parts of both vertical bars may peel off due to long-term use. Even in such cases, the impact of such unsightly parts on viewers is reduced, and the original design effect can be maintained over a long period of time with almost no change.

In addition, when opening and closing the voice reception, both abutting surfaces are horizontally rotated about the center pivot and then brought into contact or separated, but each abutting surface is formed into a convex surface with a substantially semicircular horizontal cross section. At the same time, the top of one of the convex surfaces is cut out to form a concave surface with a horizontal cross section of approximately an arc, so by appropriately setting the curvatures of the convex and concave surfaces, the above effects can be maintained. Interference between the abutting surfaces during opening and closing can be reliably avoided, and such a curvature can be easily set.

Furthermore, in order to prevent wind and rain from entering through the gaps between the opposing end surfaces of the upper and lower rails and the upper and lower end surfaces of each folding receiver, gap concealing portions (for example, Normally, the rising surfaces 2b and 3b) in the above embodiment are provided in a protruding manner. If the semicircular shape is used, the distance between the center pivot and the gap concealing part can be set to be approximately equal to the radius of the convex surface, which means that the rotation of the abutting surface caused by opening and closing of the voice receiver can be concealed by the gap. The front and rear width of the rail can be made as small as possible without being obstructed by the
It is possible to further reduce the weight of the rail and the entire folding receiver and the material cost.
