Description

[Detailed description of the invention] This invention relates to a panel connection device, especially a panel connection device when assembling indoor partition walls, and its purpose is to attach one type of frame material to the vertical edge of the panel. This simplifies the manufacturing, management, and assembly of the panels, and by connecting the frames to each other through elastic engagement of the connecting members, the panel assembly work is made simple and quick, and in particular, the connection strength in the direction perpendicular to the panel surface is improved. To provide a connecting device that is large in size and has the required bonding strength in the horizontal connecting direction of panels, and does not cause any looseness in the connecting portion of the panels in any of the front, rear, left, and right directions. .

A large number of proposals for this type of panel connection device have been known in the past, but the commonly implemented structures include (A) the use of I-frames at the opposite edges of adjacent panels; and (B) the use of adjacent panels. (C) A T-shaped frame that straddles the opposite edges of an adjacent panel;
Some mold frames are fastened together with screws.

The items described in Items B and C above require at least two types of frames to be attached to opposite edges of adjacent panels,
In addition, the products described in items A and C above require a special peripheral frame other than the panel connection frame for the outer edge of the end panel, that is, the outer edge of the panel that does not become a joint. Manufacturing, management and assembly are cumbersome.

Furthermore, in the case of Item 0, the frame is located separately on both the front and back sides of the panel, making it difficult to assemble the frame at the panel connecting portion.

This invention was devised to solve the problems of the conventional structure as described above, and its details will be explained below with reference to illustrated embodiments.

As shown in Fig. 1, this panel connection device is used when connecting panels A, which serve as partition walls, etc., with decorative panels B attached on both sides, and is used in combination with frames 1, 1 and connection member 2. Each of them is made of a metal mold material such as aluminum, a plastic mold material such as hard vinyl chloride, or a combination thereof.

Figures 2 and 3 show a typical embodiment of this invention, in which the frame 1 consists of a bottom wall 1' and inner walls 1'', 1'' projecting in the same direction from both ends of the bottom wall 1'. It is a substantially U-shaped cross section with an outward dovetail opening groove 4, and opposing locking protrusions 3 are provided on the inner surfaces of the inner walls 1'', 1''. .

The locking protrusion 3 has a cam surface 5 that slopes toward the outer end to facilitate fitting of the connecting member 2, and a slope 6 that slopes inward to engage the connecting member 2. It is roughly triangular in shape.

In addition, at the outer ends of the inner walls 1'', 1'' there are stopper parts 1 that protrude from the side edges of each panel A and determine the joint spacing of the panels A.
3.13, and a presser protrusion 7 is formed on the outer surface of the inner walls 1', 1' to hold down and lock the end face of the decorative panel B.

The connecting member 2 has a plate-shaped shaft portion 8 and wing-like elastic locking portions 9 provided at both ends of the shaft portion 8, and has a substantially square cross section.

The outer surface of the tip of the wing-like elastic locking portion 9 is
A small protrusion 10 having a slope that engages with the attracting slope 6 is provided.

When assembling, the opening grooves 4, 4 of the frame 1 are fitted and fixed to each side edge of the adjacent panels A, A so that they face each other, and then the connecting member 2 is inserted into the opposing openings. The locking protrusion 3 and the wing-shaped elastic locking portion 9 are fitted into the grooves 4, 4, and are brought into engagement with each other while abutting the opposing stopper portions 13, 13 at each fitting portion.

In addition, when fitting and fixing the frame 1 to the panel A, a recess is formed in the side edge of the panel A, and the bottom wall 1' of the frame 1 is inserted into the recess, and the bottom wall 1' is inserted into the four parts of the panel A. It is fixed to the bottom with screws 11, etc.

4 and 5 show other embodiments of this invention.

In FIG. 4, a blindfold is fitted at the joint portion where the stopper portions 13 abut each other when the panels A and A are connected.

Further, in the embodiment shown in FIG. 5, the protruding length of the stopper portion 13 is relatively short, and the paint 15 is applied to the joint.

In any of these embodiments, the structure allows the opening groove 4 of the frame 1 and the connecting member 2 to be aligned with each other very easily.

This invention consists of the above-mentioned structure, in which a frame having a substantially U-shaped cross section with an outward opening groove is fitted and fixed to each side edge of adjacent panels, and both frames are faced to each other. Since the structure is connected by a connecting member that fits into the opening groove, only one type of frame is required to be attached to the side edge of the panel, and that frame also serves as a frame for the outside edge of the panel that is not the connecting part, so it is difficult to manufacture and manage it. The standardization of assembly simplifies the installation of the product to the panel, and it can be provided at a low price.

In addition, since the part of the stopper that protrudes from the frame is a form factor, it is possible to make a reliable connection even if there is a dimensional error in the panel made of extruded material, etc., and the length of the part of the stopper that protrudes allows for joint spacing. can be determined arbitrarily.

Further, each frame and the connecting member are fitted and locked by utilizing the elasticity of the wing-shaped elastic locking portion of the connecting member, so that assembly and connection operations can be performed easily and quickly.

Further, the cam surface 5 of the locking protrusion 3 guides the wing-shaped elastic locking portion of the connecting member 2 to facilitate fitting.

Further, the engagement of the locking protrusion is such that the slope and the small protrusion of the wing-shaped elastic locking portion are attracted to each other, and the connection is strong.

Further, the frames attached to the panels are interconnected by connecting members that fit into the outward opening grooves of the frames,
In addition, since the connecting member has a shaft, the connection strength in the front-rear direction perpendicular to the panel surface is particularly high, and it is also equivalent in the panel connection direction due to the relationship between the locking protrusion and the wing-like elastic locking part. This provides a strong connection between the two and no wobbling.
