Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an assembly structure of a vertical lattice panel used for a handrail such as a balcony or stairs. The hollow material is used as it is as a handrail, and the handrail is directly connected to the upper and lower rails only by integrally bulging and deforming the locking part on the outer peripheral side of the intermediate part from the above each end to the handrail body side. The present invention relates to an assembly structure of a vertical lattice panel that can be manufactured.

[Prior Art] Generally, balconies, stairs, and the like are provided with handrails to ensure safety during use. To attach the handrails, upper and lower crosspieces and handrails are combined. It is performed by forming a vertical lattice-shaped panel body and attaching it to a column. For example, the panel assembly structure for handrails described in Japanese Utility Model Laid-Open Nos. 58-188457 and 59-150826 is provided on a horizontal member when a large number of handrails are attached to the horizontal member (upper and lower beams). Insert the upper and lower ends of the handrail into the through holes, form the engaging pieces on both the upper and lower ends and the through holes, and crimp the engaging pieces to attach the handrail to the horizontal member. It has a fixed structure.

On the other hand, when connecting the upper and lower end portions of the handrail to the upper and lower rails, a screwhole is integrally formed on the handrail separately from the above-mentioned connecting structure, and the screwhole and tapping screw are used. There is also known a method of directly fixing the end faces of the to the upper and lower rails.

However, in the former assembly structure, since the engaging pieces have to be formed on both the handrail and the upper and lower crosspieces, a lot of man-hours are required and it is troublesome to align the engaging pieces. However, in the latter method of using tapping screws, it is necessary to screw in 2 to 4 tapping screws above and below each handrail, so it takes time and the material of the handrail is Has a problem that a large amount of material is required by forming a screw hole over its entire length. In any case, in the conventional coupling structure,
There was a fatal drawback that the work process could not be simplified.

When assembling the vertical grid panel by connecting the to the upper and lower rails, both ends should be of a predetermined length without forming the engaging pieces on both the handrail and the upper and lower rails or forming the screw holes in the material of the handrail. The hollow material that has just been cut off is used as it is as a handrail, and the upper and lower rails and the handrail are simply bulged and deformed integrally on the outer peripheral side of the intermediate part from the above each end to the handrail body side. Can be directly connected without inducing slipping or rattling, and thus the assembly structure can be reasonably improved while maintaining the rigidity of the panel body, and the work process can be simplified. Assemble the vertical lattice panel assembly It is the one we are trying to provide.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the technical means adopted by the present invention are, on both sides of a plane portion having a through hole through which a handrail is inserted, on the inside in the longitudinal direction. A pair of flanges formed by extending the ridges are provided to face each other with a predetermined facing interval, and upper and lower rails arranged in parallel vertically are integrally formed in a U-shaped cross section, respectively. When both ends of the handrail are inserted into the through-holes of the crosspiece, the intermediate portion of the handrail extending from the inside of the flat surface to the ridge of both flanges is bulged toward the outer peripheral side so that The handrail is integrally formed with a locking portion that is firmly fixed to the flange protrusion.

[Operation] Therefore, according to the present invention, the hollow material whose both ends are cut off by a predetermined length is used as it is as a handrail, and the outer peripheral region of the intermediate portion of the handrail located near each end is simply The handrail can be easily and reliably joined to the upper and lower rails only by bulging and deforming, and the panel body having high rigidity can be assembled.

The width B between the tips and the inner surface distance B'of the projection 23 are substantially the same as shown in FIG.

At the same time, these intervals B and B'are substantially equal to the expected dimension A of the handrail 4. At a position where the handrail 4 is attached to the lower crosspiece 2, a through hole 25 is provided which is in contact with the inside of the ridge 23 and allows the handrail 4 to be inserted as it is. Similarly, the upper rail 3 is also provided with a through hole 25 through which the handrail 4 can be directly inserted. The lower end portion 41 of the handrail 4 is inserted into the through hole 25 of the lower rail 2, and the upper end portion 42 is inserted into the through hole 25 of the upper rail 3.

It should be noted that although the lower rail 2 is provided with the protrusion 23 in the above embodiment, the present invention is not limited to this, and the lower rail 2 may not be provided with the protrusion 23.

In the present invention, the lower bar 2 and the upper bar 3 as described above are used,
A vertical grid panel is assembled by forming a locking portion 43 described later on the outer peripheral side of an intermediate portion extending from the upper and lower end portions 41, 42 to the handrail 4 main body side.

That is, as shown in FIG. 3, an inward groove fitting portion 26 is formed between the inside of the flat portion 21 of the lower rail 2 and the protrusions 24, 24 of the flanges 22, 22. , The lower end of the handrail 4
At a position facing the groove-shaped fitting portion 26 from 41 to the intermediate portion of the handrail 4 main body side, a locking portion 43 is integrally formed by bulging deformation processing from the inside. As shown in the figure, a part of the quadrangular immediate wall surface of the handrail 4 is deformed into a circular shape in the outer peripheral direction, and is bent into the groove-shaped fitting portion 26 of the flange 22 in the longitudinal direction of the handrail 4, The inside of the plane portion 21 and the projections 24, 24 of the flanges 22, 22 tightly hold the locking portion 43.

In this embodiment, the bulging process of the above embodiment is changed to the cut-and-raised process, and the cut-and-raised portion 44 is formed. Is. In the jig 6 for deformation processing in this case, the square head 63 has a groove-shaped fitting portion 26.
The handrail 4 has the same thickness as the vertical width and is similar to the above embodiment except that the cut-and-raised portion 44 is formed by shearing, and the handrail 4 is located near the lower end portion 41 and the upper end portion 42. By forming the cut-and-raised portions 44, 44 at the intermediate portion of the above, the upper and lower edges of the cut-and-raised portions 44 are firmly adhered to the groove-shaped fitting portions 26, 26 formed on the lower rail 2 and the upper rail 3. Let the lower end of the handrail 4
41 and the upper end 42 are fixed to the upper and lower bars 3, 2.

In the connection structure of the handrail 4 and the upper rail 3, the upper end 42 of the handrail 4 is inserted from below into the through hole 25 of the upward U-shaped upper rail 3, and the upper end 42 is formed into the flanges 22, 22. Flat part 21 between
The structure is the same as the connection structure of the lower rail 2 and the handrail 4 except that it projects upward from the upper surface and becomes a vertical object.

In the above structure, when assembling the vertical grid panel, first, the lower end portion 41 of the handrail 4 is sequentially inserted into the plurality of through holes 25 assigned to the lower rail 2, and the handrail is similarly provided. The upper end 42 of 4 is inserted into the through hole 25 of the upper rail 3 and is vertically attached.

At this time, since the upper and lower end portions 41, 42 of the handrail 4 are opened vertically, when the jig 6 is inserted in this space and the shaft rod 62 is rotated by applying strong force, the jig 6 According to the selected shape of the head portions 61, 62, an intermediate portion from the upper and lower end portions 41, 42 of the handrail 4 to the main body side of the handrail 4 is bulged and deformed from the inside to the outside, and the two facing each other. Locking part that occurs on the side

Thus, the vertical lattice panel is a very simple means of integrally forming the locking portion 43 on the outer peripheral side of the intermediate portion from the upper and lower end portions 41, 42 of the handrail 4 inserted to the main body of the handrail 4. The handrail 4 which is assembled as a vertical grid panel as described above has an upper and lower end portion 4
Since the locking portion 43 or the cut-and-raised portion 44 formed on the second and the fourth portions 41 are closely adhered and fixed between the inside of the flat portion 21 and the ridges 24 and 24,
Assembling rigidity is firmly maintained without the handrail 4 coming off and rattling.

Since the order of the above assembling is not essential,
It is needless to mention that the order can be freely changed.

[Effects of the Invention] In short, the present invention requires a pair of flanges formed by extending ridges inward in the longitudinal direction on both sides of a flat surface portion having a through hole for inserting a handrail at a predetermined opposing interval. The upper rail and the lower rail, which are arranged side by side, are integrally molded in a U-shaped cross-section, and both end portions of the handrail are inserted into the through holes of the rails. The intermediate portion of the handrail extending from the inside of the flat surface to the projection of both flanges is bulged to the outer peripheral side, and the locking portion that is firmly adhered to the inside of the flat surface and the projection of both flanges is provided with the handrail. Since the upper and lower ends of the handrail are joined to the upper and lower rails to assemble the vertical grid panel, the hollow material with both ends cut off by a predetermined length can be used as it is. Located near both ends of the upper and lower rails The handrail can be easily engaged with the upper and lower rails by simply bulging and deforming the outer periphery of the handrail body, and the handrail incorporated as a vertical grid panel is formed at the upper and lower ends thereof. Since the locking part is firmly adhered to the inside of the flat part of the upper and lower rails and the ridges provided on the inside of both flanges, the handrail does not fall off, falls, rattles, etc. Is firmly held, and there is no need to form engaging pieces on both the handrail and the upper and lower rails or to form a screw hole in the material of the handrail as in the conventional case. While ensuring the safety, the working process at the time of assembling can be remarkably simplified and the labor saving of the work can be achieved.
