Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a lattice arranged on doors, shoji screens, etc.

(Prior art) When forming a lattice by intersecting a plurality of vertical members and horizontal members each having a rectangular cross section in a cross shape, the end face of the horizontal member is brought into contact with one side of the vertical member. The two can be connected by driving a screw toward the end surface of the cross member from the other side surface opposite to the side surface. However, when connecting a separate horizontal member to the other side of the vertical member, since the horizontal member has already been connected to the one side of the vertical member, screws must be driven in the same way when connecting the horizontal members. It is not possible to connect the separate cross members. From this, conventionally, the vertical member and the horizontal member disposed in contact with the other side of the vertical member are defined as angles applied to the side surface of the vertical member and the side surface of the horizontal member whose ends are in contact with this. They were connected via a connecting member such as a member or a band-shaped plate member.

However, assembling a lattice using such connecting members requires time and effort, and the appearance of the lattice assembled in this manner is significantly impaired by the connecting members.

(Purpose) Therefore, an object of the present invention is to enable a lattice to be easily assembled without arranging connecting members externally.

(Structure) The lattice according to the present invention includes a plurality of tubular first lattice members arranged in parallel to each other, and a plurality of tubular first lattice members arranged in parallel to each other and intersecting at right angles between the first lattice members. a tubular second grid member;
The lattice material has a plurality of pairs of pieces abutted against each other in the axial direction, and the abutting surfaces of each pair of pieces intersect at a non-perpendicular angle to the axis of the first lattice material and from an inclined surface that intersects at a right angle to the lattice surface. each second lattice member is connected to each piece via a fastener extending from inside each piece toward each second lattice member near the abutting surface of each pair of pieces. Furthermore, each pair of pieces is connected to each other via a connecting member disposed inside the pieces.

(Operations and Effects) According to the present invention, each pair of pieces constituting the first lattice material, and each piece and the second lattice material have a connecting member and a fastener disposed therein. connected via. Therefore,
The connecting members and the fasteners do not appear outside the grid. Therefore, it is possible to avoid the arrangement of connecting members and the damage to the appearance of the lattice that would be required in the conventional lattice assembly.

Furthermore, by making the abutting surfaces of each pair of pieces the inclined surfaces, it is possible to secure a large area of abutting surfaces, that is, opening surfaces, and thereby the connecting member and the fastener can be inserted into each piece. and the installation and therefore the assembly of the lattice can be carried out easily.

(Embodiments) The features of the present invention will become clearer from the following description of the illustrated embodiments.

As shown in FIG. 1, a grating 10 according to the present invention
A plurality of tubular first lattice members 12 arranged parallel to each other, and a plurality of tubular second lattice members 12 arranged between the first lattice members at right angles thereto and parallel to each other. 14. The lattice 10 is fitted into a frame 16 such as a frame forming a window frame, a door, or the like. In the illustrated example, the first and second lattice members 12 and 14 constitute a vertical member and a horizontal member, respectively, but they may alternatively be used as a horizontal member and a vertical member, respectively. Further, the first and second lattice members each have a rectangular cross section, but they can have other polygonal shapes other than this shape, for example.

Each first lattice member 12 is composed of a plurality of pairs of pieces 12a and 12b that are butted against each other in the axial direction. Two pieces 12a, 1 forming a pair
The abutting surface 17 of the first lattice member 12 is an inclined surface that intersects at a non-perpendicular angle with the axis of the first lattice member 12 and at a right angle with the lattice surface, that is, the opening surface of the frame body 16. This inclined surface is preferably a surface that slopes from the height of the upper surface of one second lattice material 14a to the height of the lower surface of the other second lattice material 14b, as in the illustrated example. . By forming the abutting surface 17 as the inclined surface, a large-area opening can be secured. The large area openings facilitate the insertion and installation of the fasteners 18, 19 and the connecting members 22 described below into each piece 12a, 12b, which facilitates assembly of the grid 10.

Each second grid member 14 is fixed and connected to each first grid member 12. More specifically, a pair of second lattice members 14a, 14b located on both sides of the pair of pieces 12a, 12b are connected to the pair of pieces 12a, 12b.
The pair of pieces 12a, 12 are arranged so as to face each other in the vicinity of the abutting surface 17 of the piece 12b.
b, respectively fixed and connected. In the illustrated example in which each piece and each second lattice material have a rectangular cross-sectional shape, in the vicinity of the abutting surface 17 of the pair of pieces 12a, 12b, the end surface of each second lattice material meets the abutting surface 17. It touches the side of each piece that forms an acute angle.

By configuring the first lattice material 12 with a plurality of pairs of pieces, as shown in FIG. 2, when assembling the lattice 10, the screws 18
It is possible to arrange fasteners such as these toward one of the second lattice members 14a, and to dispose the screws 19 from within the other piece 12b toward the other second lattice member 14b. By tightening the screws, each piece and each second lattice member can be fixed and connected. Each second grid member is provided with a bis pocket 20, and the screw 18 is screwed into the bis pocket 20.

As shown in FIG. 2, two pairs of pieces 12a, 12 are located at two locations where the first and second grid members intersect, which are adjacent to each other in the longitudinal direction of the second grid member 14.
b and the two pairs of second lattice members 14a, 14b, each pair of pieces 12a, 12b can be connected to each other via a rod-shaped connecting member 22 provided with threads on the outer periphery. can. Connecting member 2
2 is fixed to the insides of both pieces by firmly fitting them into bis pockets 24 formed in both pieces (see FIGS. 2 and 3).

In this way, the lattice can be easily assembled without arranging external connecting members and therefore without damaging the appearance.

In the illustrated example, a plurality of abutting surfaces 17 adjacent to each other in the longitudinal direction of the first lattice material 12 are parallel to each other, whereas a plurality of abutting surfaces 17 adjacent to each other in the longitudinal direction of the second lattice material 14 are parallel to each other. The surfaces 17 are non-parallel to each other. However, the present invention is not limited to this, and for example, the plurality of abutting surfaces 17 adjacent to each other in the longitudinal direction of the second lattice material 14 may be parallel to each other, or may be irregular instead of regular as shown in the drawing.
