Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a panel connection device.

[Purpose of invention]

The object of this invention is to provide a panel connecting device that allows easy panel connecting work and layout changes.

[Disclosure of invention]

This invention is based on a joint that is shaped like a strip and has engagement protrusions on both side edges, and has connecting pieces on both sides of the center line along its longitudinal direction, and a groove into which the connecting pieces of the joint are inserted. a panel having grooves formed along the side edges and deep in the grooves to engage with the engagement protrusions, and the joint inverter is formed along the longitudinal direction of the grooves of a pair of adjacent panels. In the panel connecting device that connects the pair of panels to each other by inserting each connecting piece, the groove of the panel is arranged such that each connecting piece of the joint a first groove into which is inserted, a second groove into which each connecting piece of the joint inverter is inserted with the pair of panels bent at a predetermined angle; The second groove is formed along a corner of a side end of the panel, and the opening of the first groove and the second groove are common. Therefore, since the jointer is inserted from the end of the slit, the connection work is facilitated. And 1
Various types of joints can be used to connect in straight lines and at right angles, making it easy to change the layout. Furthermore, if an exposed part for removal is formed in the center of the jointer,
It becomes easier to operate the joystick.

An embodiment of this invention is shown in FIGS. 1 to 4. That is, 1 and 2 are panels, 3a to 3d are grooves, 4a and 4b are joint inters, and grooves 3a to 3d are grooves.
3d is formed along the corner 2 of the side edge of the panels 1, 2, and has an opening at the corner and at least an opening at the upper end. In addition, the cross-sectional shape of the grooves 3a to 3 forms an angle θ (=67.6°) from the side surfaces of the panels 1 and 2, and a first grooved line 5 is formed on the panel side surface side a predetermined distance inside the inner surface of the grooves 3a to 3d. Furthermore, a second groove 6 is formed on the inner panel surface side. In this shape, a pair of panels 1 and 2 are arranged in a straight line and face each other as shown in FIG. 2, and the angle formed by both grooves 3a, 3b or 3c, 3d is 2θ (=135°).
The jointers 4a and 4b are in the form of rigid strips, and their cross-sectional shape is the same as the cross-sectional shape of the grooves 3a, 3b or 3c, 3d excluding the first groove 5 when the panels 1 and 2 are arranged in a straight line. They have almost the same shape. That is, the central part on the center line along the longitudinal direction of the strip is bent at 135° (=2θ), and on both sides there are connecting pieces 9 having the same thickness as the width of the grooves 3a to 3d.
10, and engagement protrusions 7 are formed on both side edges to engage with the second grooves 6 when the panel is arranged in a straight line as shown in FIG. Further, an exposed portion 8 for removal is formed on the outwardly curved side of the central portion. This Jyo Inta 4
a and 4b are connected by being inserted from the upper end openings of the grooves 3a to 3d. Moreover, when removing it, it can be pulled out upward by lifting the exposed part 8.

2 shows the panels 1 and 2 arranged in a straight line, whereas FIG. 3 shows the panels 1 and 2 arranged at right angles. In this case, the angle formed by the opposing grooves 3a and 3d is 135°, which is opposite to the above. Also, side 1 of panels 1 and 2
A and surface 2b are arranged so that surface 1b and side surface 2a of panels 1 and 2 are flush with each other as shown in the figure. Then, in the joint 4a, the connecting pieces 9 and 10 are inserted into the grooves 3a and 3b from the openings at the upper ends of the grooves 3a and 3b, with the front and back reversed compared to the case of the linear connection.
The engagement protrusion 7 is engaged with the first groove 5. That is, the shape formed by the grooves 3a and 3b in the linear arrangement and the right-angled arrangement of the panels 1 and 2 is the same as the shape in the linear arrangement excluding the first grooved line 5 and the shape in the right-angled arrangement excluding the second grooved line 6. They are of the same size and symmetrical. Therefore, when the panels 1 and 2 are arranged in a straight line, the grooves into which the connecting pieces 9 and 10 of the jointers 4a and 4b are inserted are defined as the first groove parts, and when the panels 1 and 2 are arranged in a bent manner, the jointers 4a and 4b are inserted. When the groove portion into which the connecting pieces 9 and 10 of 4b are inserted is defined as a second groove portion, the first groove portion and the second groove portion are formed in common including the opening thereof.

Figure 4 shows the T-shape (solid line) of panels 1 and 2,
and a cross-shaped connection (including the imaginary line), the connection portion of which is similar to the right-angle connection shown in FIG.

Because of this configuration, this panel connecting device has the following advantages. That is, joint inter 4
Panels 1 and 2 can be connected in a straight line, L-shape, T-shape, or cross shape by simply inserting panels 1 and 4b from the upper ends of panels 1 and 2.
Only one type of a and 4b is sufficient. Since the exposed portions of the jointers 4a and 4b are exposed outside the panels 1 and 2, the jointers 4a and 4b can be easily removed and can be easily recombined when changing the layout of the panels 1 and 2. Particularly when a large number of panels are connected in a straight line, meandering of the panels becomes a problem, but in this embodiment, the jointers 4a and 4b are inserted into both corners of the panels 1 and 2, so that wobbling is reduced.

A second embodiment of this invention is shown in FIGS. 5 to 7. That is, in this panel connecting device, two circular parts 5', 6' are formed deep inside the cross sections of the grooves 3'a, 3'b, and these circular parts 5', 6' are connected to the first circular parts 5', 6'. The grooved line 5 corresponds to the second grooved line 6. Further, the engagement protrusion 7' of the jointer 4' also has a circular cross section to fit into the circular portions 5' and 6'. The other configurations are the same as in the first embodiment, and the straight connections and right angle connections are also the same. Note that in both the first and second embodiments, the grooves 3a, 3b or 3'
Although the angle formed by a and 3'b is 135 degrees, the slit width can be minimized compared to other angles, which is preferable in terms of appearance.

A third embodiment of this invention is shown in FIGS. 8 and 9. That is, in this panel connection device, the angle formed by the central bent part of the jointer 4'' is 90°, and each groove 3''a, 3''b can be connected in a straight line or at a right angle. Since each part corresponds to the first embodiment, it is indicated by the same reference numeral with a dot.

The fourth embodiment of this invention is shown in FIGS. 10 and 1.
Shown in Figure 1. In other words, this panel connection device:
The joint inter 4 is U-shaped, and each groove 3
A and 3b are formed correspondingly as shown in the figure. Since the function is the same as that of the first embodiment, a dash is attached.

[Effect of idea]

As described above, the panel connecting device of this invention has the advantage that it is possible to easily connect panels and change the layout.
