Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a vertical bar for connecting horizontal bars made of an extruded material such as aluminum.

[Conventional technology]

Screws are generally used to connect vertical and horizontal bars made of extruded sections. For example, in a conventional panel lattice installed in front of a bay window, the vertical bars are formed into a square cross-section, and the vertical bars and horizontal bars are connected by screwing screws into the screw pockets of the horizontal bars through holes drilled in the side walls. was. However, in this connection method, the direction of the screws protruding from the vertical beam is limited to the direction perpendicular to the side wall of the vertical beam, so the horizontal beam can only be connected at right angles to the side wall of the vertical beam. If sleeves are provided at both left and right ends of the screen lattice on a backward slope to match the protruding shape of the bay window, extruded sections with a square cross-section can be used for the vertical bars between the main body of the screen lattice and the sleeves. However, it is necessary to separately extrude and use vertical bars with irregular cross-sectional shapes such as trapezoids that can be connected by changing the direction of the horizontal bars, which is more costly than using vertical bars with the same cross-sectional shape for all. There was a drawback.

[Purpose of invention]

In view of the above-mentioned circumstances, this idea was developed to create a horizontal beam that can be selectively connected at right angles to the side wall or at a certain diagonal angle even if the cross-sectional shape is the same. The purpose is to provide a vertical crosspiece for connecting crosspieces.

〔composition〕

The structure of this invention to achieve the above object consists of a pair of extruded members and a splint having screw holes for fixing both members with screws.
Both members have a cross section L consisting of one side wall and one wall.
A connecting piece that is hooked to the face wall of the other member is provided protruding near the widthwise tip of the inner surface of the side wall, and a plate-like high protrusion with a V-shaped opening is provided in the center of the width. It has a cross-sectional shape in which low protrusions are protruded on both left and right sides away from the center of the width, and slopes in the height direction are formed at the tips of both protrusions, and when assembling the two members, at least one member A through hole for an assembly screw to be screwed into the screw hole of the splicing board is provided in the side wall of the side wall and the face wall of the other member, and for connection with the horizontal beam,
A through hole for a connecting screw to be screwed into the screw pocket of the horizontal crosspiece is provided between the high protrusion and the low protrusion on either the left or right side wall, and the head of the connecting screw is inserted between the high protrusion and the low protrusion. The gist is that it can be selectively hung on the protrusion or on the periphery of the through hole by means of a notch in the high protrusion.

[Effect]

According to the above configuration, before assembling the two members, after connecting the horizontal beam to one or both of the members, the vertical beam is assembled by combining both the members with the splint and assembly screws. When connecting the horizontal beam at right angles to the side wall of the vertical beam, cut out the high protrusion so that the head of the connecting screw does not get caught in it, and connect it to the screw pocket of the horizontal beam from the through hole in the side wall. Screw in the screw. In addition, when connecting at a diagonal angle, if the end face of the horizontal beam is cut at approximately the same angle as the slope angle of the high protrusion and low protrusion, the horizontal beam can be arranged perpendicular to the slope and the horizontal beam can be connected to the vertical beam. Since it can be placed against the side wall, hook the head of the connecting screw between the high protrusion and the low protrusion and screw the connecting screw into the screw pocket through the hole.

〔Example〕

Next, an embodiment of this invention will be described based on the drawings.

The drawing shows a case in which this invention is applied to the vertical beams of the lattice of a bay window.

The bay window A is narrower between the left and right vertical frames 2 and 2 of the front part than between the left and right vertical frames 1 and 1 of the window opening, and has a protruding shape like a trapezoid when viewed from a plane. 3 is a plate glass that seals both sides, and 4 is a sliding shoji that opens and closes the front.

The panel lattice B has sleeves 6, 6 parallel to the side surfaces at both left and right ends of the main body 5 parallel to the front surface of the bay window A, and at the center of the width of the panel lattice main body 5, at its left and right ends, and at the rear end of the sleeves 6. Vertical bars Pa, Pb, and Pc (hereinafter collectively referred to as P) are provided respectively, and horizontal bars 7 and 8 are provided between adjacent vertical bars P and P.
The horizontal bars 7 and 8 are connected to the vertical bars P by sandwiching the connecting screws 10 passing through the side walls 9 of the vertical bars P and screwing them into the screw pockets 11 of the horizontal bars 7 and 8,
Each vertical beam 4 is supported by a bay window A via an arm plate 12.

Each vertical bar P is formed hollow with the same square cross section, and both the main and sub members 1 with the same cross section shape
It consists of 3,14 combinations. Both the main and sub members 13 and 14 are one side wall 9 on either the left or right side of the vertical beam P.
A connecting piece 16 is provided protruding from the inner surface near the widthwise tip of the side wall 9, and a mating member 13 or Projections 17 and 18 are provided in contact with the inner surfaces of the face walls 15 of 14, and grooves 1 between the side walls 9 of the mating member and the projections 17 are provided on the inner surfaces of the tip ends of both walls 15.
A projecting edge portion 20 that fits into the side wall 9 is provided, and a projecting piece 21 that faces the connecting piece 16 of the mating member is provided on the inner surface near the base end of the side wall 9. In addition, plate-shaped high protrusions 22, 22 are provided in the center of the width of the inner surface of the side wall 9 in a V-shaped opening,
Triangular low protrusions 23 on both sides away from the center of the width,
23, and both protrusions 22, 23 are provided with slopes 24, 25 in the height direction.

Regarding the combination of the main and sub-members 13 and 14 of the vertical beam P, if the main member 13 is the member on which both walls 15 face the bay window A side, the connecting piece 16 of the sub-member 14 and the projecting piece of the main member 13 21 and the splice plate 2 on the inside.
6, fix the splint 26 to the connecting piece 16 with the screws 27, and tighten the assembly screws 28 used for attaching the arm plate 12.
is passed through the end piece 29 of the arm plate, both walls 15 of the main member 13 and the connecting piece 16 of the sub member 14, and the splice plate 26
Both the main and sub-members 13, 14 are assembled by screwing into the screw holes 30 of and tightening them. Reference numerals 31, 32, and 33 are through holes for the assembly screws 28. By tightening the assembly screws 28, the overlap between the face wall 15 and the connecting piece 16 is maintained, and the protruding edges 20 at the tips of both ends 15 are aligned with the grooves 1 at the base end of the connecting piece 16.
9, both members 13,
14 is maintained, and the predetermined form of the vertical bar P is stabilized.

Next, regarding the connection between the vertical bar P and the horizontal bars 7 and 8,
Through holes 34 and 35 for the connecting screw 10 are provided in the side wall 9, and the holes are formed between both the protrusions 22 and 23. When connecting the horizontal bars 7 and 8 in a direction perpendicular to the side wall 9, such as the vertical bar Pa at the center of the width of the grid body 5 and the vertical bar Pc at the rear end of the sleeve part 6, the high protrusion 22 is cut out. The head 10a of the connecting screw 10 is brought into contact with the inner surface of the side wall 9, and the head 10a is attached to the peripheral edge of the through hole 34.
Vertical and horizontal bars can be connected in the normal state where However, even when the horizontal bars 7 and 8 are connected by being inclined with respect to the side wall 9 like the vertical bar Pb between the face grid body 5 and the sleeve part 6, the inclination of the connecting screw 10 screwed into the screw pocket 11 is head 1 in the direction
Because the connecting screw 10 hangs on both the height protrusions 22 and 23 of the vertical beam P at a good angle due to the difference in height, the connecting screw 10
By stably tightening, a stable connection of the vertical and horizontal bars can be obtained.

Since each vertical bar P consists of both main and sub members 13 and 14 in this way, when installing the surface grid B, first, each of the members 13 and 14 of the vertical bar Pa in the center and the vertical bar Pb at the corner Horizontal bars 7 are arranged in between to assemble the left and right halves of the grid main body 5 as single units, while horizontal bars 8 are also installed between each member 13, 14 of the vertical bars Pb at the corner and the vertical bars Pc at the rear end. After assembling the sleeve part 6 by arranging the arm plates 12, the main and sub-members 13 and 14 are connected, so that the vertical beam P can be assembled and the entire surface lattice B can be assembled at the same time. can.

Furthermore, since the surface lattice B can first be assembled as a single unit divided into several parts in this way, the single units can be assembled in a factory and then the whole can be assembled on site.

[Effects of the invention] As explained above, according to the vertical bar of this invention, the horizontal bar can be selected either at right angles to the side wall or at a certain oblique angle in the same cross-sectional shape, making it suitable for mass production and cost effective. It has an excellent effect of being advantageous to

In addition, since it is a combination of a pair of members each having one side wall and one side wall of a vertical bar, when making side lattices, muntins, and other products using this,
Even if it is a large product that extends horizontally,
By assembling a plurality of separate units in a factory, storage and shipping can be advantageously carried out, which is very convenient.
