Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a connecting device for unitary furniture panels, fittings panels, etc., which can be assembled and disassembled.

(Prior Art) A conventional coupling device of this type is shown in FIG. This is done by fitting the fitting groove D1 of the female body C into the male body B1 which is fitted and fixed into the panel A1,
The male body B2, which is fitted and fixed to another panel A2, is fitted into the other fitting groove D2 of the female body C.

(Problems with the Prior Art) In the conventional coupling device, the male bodies B1 and B2 are made of plastic, and the female body C is made of metal, so there are the following drawbacks.

(1) Fitting grooves D1 and D2 for female body C in male bodies B1 and B2
When fitting..., the female body C may be slightly scraped by the male bodies B1 and B2. Therefore, when the panels A1 and A2 are assembled and disassembled several times, gaps are created between the male bodies B1 and B2 and the female body C, causing them to wobble.

(2) Because the hardness of the metal female body C and the wooden panels A1 and A2 is vastly different, the female body C and panel A
As 1 and A2 become more familiar, they tend to come off easily.

(3) Since the color of the metal female body C is limited, it is difficult to harmonize with the color of the wooden panels A1 and A2, and the color may become unbalanced.

(4) If the dimensions of the female body C and the male bodies B1 and B2 are slightly different, they will not fit smoothly and will be difficult to assemble.
Also, both of them are poorly settled.

(5) Since the female body C is made of metal, it is cold and has a rough texture. Also, the cost will be high.

(6) Both longitudinal end surfaces of male bodies B1 and B2 have fitting grooves D.
It looks bad because it is exposed from 1, D2...
There was also a risk that the male bodies B1 and B2 would slip out of the fitting grooves D1 and D2.

(Objective of the Invention) The present invention eliminates the various drawbacks mentioned above by making not only the male body but also the female body made of plastic, and also prevents one longitudinal end of the male body fitted into the groove of the panel from slipping out from the groove. At the same time, the goal is to improve appearance by making it invisible from the outside.

(Means for Solving the Problems) The connecting device for unit panels, etc. of the present invention includes a male body 1 (Fig. 3) that is fitted and fixed into a groove 5 of a connecting body 3 such as a panel, and a male body 1 that is fitted into the groove 5 of a connecting body 3 such as a panel. The male body 1 and the female body 2 are both made of plastic, and the male body 1 has a fitting protrusion 7 connected to a fitting part 6 that fits into the groove 5 of the connecting body 3. The inset part 6
A plurality of tapered wedge-shaped retaining protrusions 8 are connected to each other, and the fitting protrusion 7 is formed so as to protrude to the outside of the connecting body 3 when the fitting part 6 is fitted into the groove 5.
A recess 11 (FIG. 5) that is one step lower than the fitting protrusion 7 is formed at the base of the fitting part 6, and one longitudinal end surface 12 of the fitting part 6 is connected to the one longitudinal end surface 1 of the fitting protrusion 7.
3 and lower inside (left side of Figure 3)
The female body 2 is formed with two or more fitting grooves 16 into which the fitting protrusion 7 of the male body 1 can fit.
A fitting edge 10 that fits into the recess 11 of the male body 1 is formed at the tip of the side wall 16a of the connector 6 to prevent the longitudinal end surface 14 of the groove 5 of the connector 3 from penetrating into the side surface 15 of the connector 3. It is curved inward to match the curvature of one end surface 12 of the insertion portion 6 of the male body 1 (FIG. 6).

(Function) To use the coupling device according to the present invention, the fitting part 6 of the male body 1 is fitted and fixed in the groove 5 of the coupling body 3 as shown in FIG. As shown in FIG. 2, fit the fitting groove 16 of the female body 2 into the female body 2.
The fitting protrusion 7 of the male body 1 that is fitted and fixed to the other connecting body 3 may be fitted into the vacant fitting groove 16 . As a result, the connecting bodies 3 are connected on all sides, and a unit furniture is assembled.

If a decorative fitting body 17 is fitted into the empty fitting groove 16 into which no panel is fitted, as shown in FIG. 8, for example, the appearance will be good when viewed from the outside. Incidentally, the decorative fitting body 17 is obtained by removing the fitting part 6 of the male body 1, leaving only the fitting protrusion 7 and the recess 11, as shown in FIG.

In order to disassemble the assembled unit furniture, it is sufficient to disassemble the male body 1 and the female body 2 which are fitted into each other.

(Example) FIGS. 2 to 8 show examples of the present invention. In these figures, 1 is a male body, 2 is a female body, and 3 is a connecting body such as a unit furniture panel or a panel for fittings.

In the present invention, both the male body 1 and the female body 2 are made of plastic, and the connecting body 3 is made of wood.

The male body 1 has a groove 5 formed in the circumferential surface 4 of the connecting body 3.
A fitting protrusion 7 is connected to a fitting part 6 that is fitted and fixed inside, and the fitting protrusion 7 projects to the outside of the circumferential surface 4 of the connecting body 3 when the fitting part 6 is fitted and fixed in the groove 5. It's connected like that.

The fitting portion 6 is formed by connecting a plurality of tapered wedge-shaped retaining protrusions 8.

Inside the fitting protrusion 7 is a male body 1 as shown in FIG.
When the fitting part 6 is fitted into the groove 5, a recess 11 into which the fitting edge 10 of the female body 2 fits is formed between the peripheral surface 4 of the connecting body 3 and the inner surface 9 of the fitting protrusion 7. .

The fitting portion 6 has one longitudinal end surface 12 lowered inwardly than the longitudinal one end surface 13 of the fitting protrusion 7, as shown in FIG. 3, and is curved inward (toward the left side in the drawing). As a result, when the fitting part 6 is fitted into the groove 5 opened in front of the circumferential surface 4 of the connecting body 3, the end surface 13 of the fitting protrusion 7 of the male body 1 is exposed to the side surface 15 of the connecting body 3. One end surface 12 of the portion 6 is not exposed to the side surface 15.

The female body 2 is attached to the mating protrusion 7 of the male body 1 as shown in FIG.
Four fitting grooves 16 are formed at 90 degree intervals, into which the fitting can be fitted. Further, a fitting edge 10 that fits into the recess 11 of the male body 1 is formed in an arrow shape at the tip of the side wall 16a of the fitting groove 16.

(Effects of the invention) The connecting device for unit panels, etc. of the invention has the following effects.

(1) Since both the male body 1 and the female body 2 are made of plastic, the fitting between them is extremely smooth, and assembly and disassembly work is extremely easy.

In addition, since the male body 1 and the female body 2 fit together well, the connection between the two becomes reliable.

(2) Since the mating and disassembly of the male body 1 and the female body 2 are smooth, even if they are frequently assembled and disassembled, there is no possibility that the female body 2 will be scraped by the male body 1 or that the female body 2 will be damaged. Therefore, there is no gap between the male body 1 and the female body 2, and the connection can be ensured even after repeated use.

(3) One longitudinal end surface 12 of the fitting part 6 is lowered inward from the one longitudinal end surface 13 of the fitting protrusion 7, and the one longitudinal end surface 14 of the groove 5 of the connecting body 3 is penetrated into the side surface 15 of the connecting body 3. Since it is designed not to
Even if the male body 1 is inserted into the groove 5 as shown in the figure, the inserted part 6
One end surface 12 is not visible from the side surface 15 of the connecting body 3, giving a good appearance. In addition, since the fitting part 6 does not come off in the direction of the side surface 15 of the connecting body 3,
The male body 1 is difficult to come off from the connecting body 3, and the connection becomes even more reliable.

(4) When forming the groove 5 of the connecting body 3 with a circular saw,
Normally, it is very difficult to form the groove 5 so that the end surface 14 in the longitudinal direction does not penetrate through the side surface 15 of the connecting body 3, but in the present invention, the end surface 14 in the longitudinal direction of the groove 5 as shown in FIG. Since the grooves 5 are curved inward, it is easy to form the grooves 5 so that they do not penetrate the side surfaces 15 of the connecting body 3.

(5) A recess 11 is formed at the base of the fitting part 6, and a fitting edge 10 that fits into the recess 11 is formed at the tip of the side wall 16a of the fitting groove 16, so that the male body 1 and the female body 2 can be fitted easily. The match is guaranteed.

(6) Since the fitting part 6 is formed by connecting a plurality of tapered wedge-shaped retaining protrusions 8, the connection between the fitting part 6 and the connecting body 3 becomes reliable and strong.

(7) Since the female body 2 is also made of plastic, it is lighter and easier to handle than a metal one, making assembly and disassembly work easier.

(8) Since the color of not only the male body 1 but also the female body 2 can be freely selected to match the color of the panel, the connecting parts are not noticeable and a sense of unity with the panel is created.

(9) Costs can be significantly reduced compared to metals, so we can provide inexpensive products.
