Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a connection structure for connecting the ends of cross members at right angles to the side surfaces of vertical members in the assembly of structures such as advertising boxes, for example.

Conventionally, this type of connection structure is generally known in which the vertical members and the horizontal members are fixed in place with screws or rivets using L-shaped metal fittings, but it requires considerable skill to accurately connect them in the specified positions. In addition, there were other drawbacks, such as the fact that the connection work was time-consuming.

The purpose of this project is to obtain a connecting structure between vertical members and horizontal members that eliminates the drawbacks of the conventional method. Explain.

In FIG. 4, the vertical member 1 has two ridges 3.3 protruding from the horizontal member connecting surface of a flat vertical member main body 2 along the longitudinal direction of the vertical member.

The cross section of the support ridge 3.3 is approximately L, which consists of a base plate 4 that stands up from the surface of the vertical member body 2, and a support plate 5 that extends from the tip of the base plate 4 in the lateral direction of the vertical member 1. In the figure, the pair of receivers has protrusions 3.3 spaced apart appropriately, with the L-shaped dark openings pointing in opposite directions.

The horizontal member 6 has protrusions 12 extending from the left and right ends of the upper plate 7 and the lower plate 8 in the horizontal member main body 11 having a rectangular cross section and consisting of upper and lower plates 7.8 and left and right side plates 9°10. .12 and 13.
13 protrudes at a right angle.

Here, the inner distance d1 between the left and right side plates 9 and 10, (the hook is 1
2.12 or 13.13) is slightly wider than the outer distance d2 of the ridges 3, 3 between the pair of supports on the longitudinal member 1.

14... is a rib. Regarding the vertical members 1 and horizontal members 6 having the above structure, first, at the position where the horizontal member 6 to the vertical member 1 is to be connected, the receiver is attached to the protrusion 3.3 above the cross member and to the lower plate 7.8. Cut grooves 15.15 and 16.16 are provided with saw teeth or the like at corresponding positions and widths, and then, at the ends of the cross members 6 to be connected, hooks are made with protrusions 12, 12 and 13°1.
3, the vertical member supports are provided with cut grooves 17.17 and 18.18 using sawtooth or the like at the positions corresponding to the plates 5, 5, so that each phase is formed at the end of the protrusion. The small and medium hooks corresponding to the shaped grooves form pieces 19.19 and 20.20.

In addition, in the figure, each rib 14... is also provided with a cut groove for convenience of work.

The connection structure shown in the first diagram has a cross member 6 at the cross member connecting position of the vertical member 1.
The ends of the lower plates 7, 8 are abutted at right angles, and the ends of the lower plates 7, 8 are cut into the grooves 15, 15 and 16 of the longitudinal members as shown in the second figure.
．． 16, and the ends of the left and right side plates 9 and 10 are fitted into the grooves 15.16 and 15.16 between the grooves 15.16 and 15.16.
', 3' is fitted on the outside, and then the hook is 19.19
And 20.20 is the L of the protrusion 3.3 as shown in the third diagram.
It is constructed by being folded into a shaped groove.

In the above connection structure, the hook is piece 19, 19.20.2
0 is locked on the inside of the plates 5, 5, mainly to prevent the horizontal member 6 from coming off in the vertical direction with respect to the front surface of the vertical member 1.
The lower plates 7, 8 fit into the cut grooves 15, 15, 16, 16 to prevent vertical movement of the cross member 6, and
The right side plates 9 and 10 are fitted onto the protrusions 3' and 3',
Movement of the cross member 6 in the left and right direction is prevented, and together, the vertical member 1 and the cross member 6 are reliably connected at a predetermined position.

In other embodiments shown in FIGS. 5 and 6, the main body 11a of the horizontal member 6a has a U-shaped cross section consisting of an upper plate 7a and left and right side plates 9a, 10a, and the protrusions 13, 13 are omitted. This is an example.

Note that the other symbols indicate substantially the same components as the corresponding symbols in FIGS. 1 to 4.

In still another embodiment shown in FIGS. 7 and 8, the ridges 3b of the vertical members 1b extend from the tip of the base plate 4b in the left and right directions.
b, 5b are extended, and the left and right side plates 9b of the cross member 6b are extended.
, 10b is an example in which the inner distance between the ridges 3b is slightly wider than the outside distance between the protrusions 3b.

Note that the other symbols indicate substantially the same components as the corresponding symbols in FIGS. 1 to 4.

Another embodiment shown in FIGS. 9 and 10 has a board 4C and a plate 5C on the vertical member IC, with a protrusion 3C protruding from the upper plate 7C of the horizontal member 6C and the left and right side plates 9C510C. One hook on the main body 11C is provided with a protrusion 12C, and the left and right side plates 9C of the cross members, the inner spacing of the IOC is
This is an example in which the outer spacing is slightly wider than that of C.

Note that the other symbols indicate substantially the same components as the corresponding symbols in FIGS. 1 to 4.

The vertical members and horizontal members of the present invention are not limited to aluminum alloy, but may be made of other appropriate metals or synthetic resins.

According to the connection structure between the vertical members and the horizontal members of this invention, instead of using L-shaped metal fittings, screws, etc. as in conventional structures, the ends of the horizontal members are fitted into the grooves made in the protrusions in the receivers of the vertical members. By folding the hanging pieces into the ridges as they fit together, it is possible to accurately and easily connect the vertical members and horizontal members in the specified position without requiring any skill, and the connecting work can be performed easily and quickly. This makes it extremely convenient in practice for use in assembling various structures.
