Description

[Detailed description of the invention] [Industrial application field] This invention relates to a lattice frame that is attached to a ceiling or wall, for example, and is used for hanging and displaying products.

[Conventional technology]

Conventional lattice frames are assembled by connecting a large number of bars of a certain length by connecting the ends in two directions with L-shaped joints, the ends in three directions with T-shaped joints, and the ends in four directions with ten-shaped joints. .

[The problem that the idea attempts to solve]

Since three types of joints are used, there is a problem in that the cost increases significantly and it takes time and effort to manage each type of joint.

[Means to solve the problem]

In order to solve the above problems, this invention arranges a plurality of long bars having two grooves alternately along the entire length of both sides in the longitudinal direction at a predetermined interval, and A short bar material having two alternating grooves is interposed between the parallel long bar materials, and the ends of the short bar materials are faced at a required position on the side of the long bar material, and both ends of the connecting plate are It is constructed by fitting into the grooves of the long bar material and the short bar material, and fixing this connecting plate to the long bar material and the short bar material via screws.

[Effect]

First, the required number of long bars are arranged at a predetermined interval.

Next, the end faces of the short bars are made to face the side surfaces of the long bars, and a required number of parallel short bars are interposed between the long bars.

After fitting both ends of the connecting plate into the grooves of the long bar material and the short bar material, both ends of the connecting plate are fixed to the long bar material and the short bar material via screws to create a lattice grid. Assemble the frame.

〔Example〕

In the figure, reference numeral 1 denotes a long bar material having two alternating grooves 2 along the entire length of both sides in the longitudinal direction, and this long bar material 1 is vertically spaced at a constant interval as shown in FIG. Arrange the required number of books.

3 is a short bar material having two alternating grooves 4 along the entire length on both sides in the longitudinal direction, and this short bar material 3 is as follows:
As shown in FIGS. 1 to 3, a required number of long bars 1 are interposed in parallel so as to form a lattice shape between the long bars 1 with their end faces facing the side surfaces.

5 is the groove 2 of the long bar material 1 and the groove 4 of the short bar material 3
Both ends of the connecting plate 5 are fixed to the long bar material 1 and the short bar material 3 via screws 6.

As shown in FIGS. 3 and 4, the above-mentioned connecting plate 5 has a step at both ends by a bent part in the middle, and one end is placed in the groove 2 located on the surface side of the long bar material 1.
The other end is fitted into the groove 4 located on the back side of the short bar material 3, or the other end is made into two prongs from the middle, and the two prongs at the other end are placed on the front side of the short bar material 3. and a flat connecting plate (not shown) that fits into the grooves 4 on both sides and the back side, and one end of which fits into the groove 2 located on the back side of the long bar material 1.
The both ends of the long bar material 1 and the short bar material 3 may be fitted into the grooves 2 and 4 on both front surfaces or the grooves 2 and 4 on both back surfaces of the long bar material 1 and the short bar material 3.

In addition, in the case shown in the figure, the method of fixing with screws 6 involves forming through holes 7 that penetrate from the front surface of the long bar material 1 and short bar material 3 to the grooves 2 and 4 on the back side, and through holes 8 at both ends of the connecting plate 5. The screws 6 inserted into the through-holes 7 and 8 that are provided and matched are inserted into screw holes provided so that the grooves 2 and 4 on the back side of the long bar material 1 and the short bar material 3 and the back surface thereof pass through. 9, but a nut may be screwed into the protruding end portion of the screw 6 that protrudes from the back surface of the long bar material 1 and the short bar material 3.

As shown in the figure, by making the through hole 7 between the surfaces of the long bar material 1 and the short bar material 3 and the surface side grooves 2 and 4 large in diameter through which the head of the screw 6 passes, the long bar material 1 and the short bar material 3 can be The heads of the screws 6 are not exposed on the surfaces of the bar material 1 and the short bar material 3.

Furthermore, as shown in FIG. 5, the assembled lattice frame A is attached to the ceiling 11 by attaching both protrusions 14 of the hanging fitting 13, whose upper end is supported via the fixing device 12 consisting of bolts and nuts, to the long bar material 1. In the case where it is fitted into the grooves 2 on both sides and hung on the ceiling 11, and in the case where it is supported by screwing the wood screws 15 inserted into the through holes 7 and screw holes 9 into the wall 6 as shown in Fig. 6. and the seventh
As shown in the figure, the downward protruding pieces 17 and the upward protruding pieces 17 of the two upper and lower supports 18 attached to the wall 16 via wood screws 15 are fitted and locked into the grooves 2 on both sides of the long bar material 1. In some cases, clothing and the like are hung and displayed on the lattice frame A, for example, via hangers.

Note that the long bar material 1 with grooves 2 and the short bar material 3 with grooves 4 are formed by bending metal plates in the illustrated case, but they may be formed from aluminum shapes.

〔effect〕

As described above, according to the lattice frame of this invention, parallel short bars are interposed at predetermined positions between parallel long bars, and connected to grooves between the long bars and the short bars. Since both ends of the plate are fitted and both ends of the connecting plate are fixed to the long bar material and the short bar material via screws, the lattice frame can be assembled using one type of connecting plate.

Furthermore, since alternate grooves are provided on both sides of the long bar material and the short bar material, the ends of the short bar material can be fixed to both sides of the long bar material via connecting plates.
