Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a hinge having a plurality of hinge members.

(Prior art) Various types of hinges have been proposed in the past, but most of these hinges are independent, and even if a part is damaged, the entire hinge must be replaced. Must be. Furthermore, in the case of conventional hinges, it is necessary to select a hinge having an appropriate size depending on the mounting location.

Therefore, when we examine conventional hinges in more detail, we find that, for example,
There is a hinge as shown in the figure. As shown in FIGS. 6 and 7, this hinge is made by integrating a pair of clamping pieces 31 with a pivot hole 32 through which a support fitting on the gate post side is inserted, through a connecting part 33. The gate body 3 is attached to the tip of each clamping piece 31.
A locking portion 34 is formed to clamp the protrusion 38 on the 7 side to prevent it from coming off. The pair of clamping pieces 31 are screwed into the screw holes 36 of the screws 3.
5. Therefore, if one of the hinges shown in Japanese Utility Model Application Publication No. 51-75039 is damaged, only the damaged one needs to be replaced; Since it is sufficient to support the support hole 32, there is no need to make the size suitable for the installation location.

However, the hinge shown in the above publication requires the formation of a protrusion 38 on the side of the gate body 37 to which the locking part 34 is to be locked; If the gate body 37 is not formed, even if both clamping pieces 31 are tightened with the screws 35, the gate main body 37 cannot be securely fixed to the gate post. That is, this hinge does not have general versatility because the protrusion 38 must be formed on the side of the gate main body 37.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned circumstances, and the problem to be solved is the lack of versatility in conventional hinges.

The purpose of this invention is to create a hinge that is extremely simple in structure and installation work, has excellent compatibility, can be freely changed in size, and does not require any special processing on the flat plate part to which it is attached. Our goal is to provide the following.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by the present invention are described with reference numerals used in the embodiments. edge 21 of
a pair of arm portions 11 that clamp the pair of arms 1; a connecting portion 14 that integrally connects the pair of arm portions 11 and has a pivot hole 13 through which the pivot shaft 12 is inserted;
A locking part 15 is formed protruding inside one side of the plate part 1 and is locked in a locking hole 22 formed in the edge 21 of the flat plate part 20, and a locking part 15 is formed on the opposite side of the shaft support hole 13 of the locking part 15. At least two or more hinge members 10 having screw holes 16 formed opposite to each other in a pair of arm portions 11 are connected to each other by a pivot shaft 12 inserted into each shaft support hole 13. By sandwiching the flat plate part 20 between the pair of arm parts 11 of each hinge member 10 and inserting the pivot 12 into the shaft support hole 13 of each hinge member 10, A hinge characterized in that a flat plate part 20 can be connected in an openable and closable manner.

In the embodiment shown below, there are three hinge members 10.
The case where .

Therefore, this hinge member 10 is used in the following manner. That is, first, the locking holes 22 are formed at predetermined positions in each of the flat plate parts 20 that constitute the box, the lid, and the like. Then, the first hinge member 10 is forcibly fitted to the edge 21 of one of the flat plate parts 20 (preferably a flat plate part on the lid side that can be moved freely), and the flat plate part 20 is to hold.

At this time, the locking portion 15 is formed so that its height increases sequentially from the end edge side of the arm portion 11 toward the connecting portion 14 side, and since the hinge member 10 is formed of plastic, each The arm portion 11 is bent and can be easily fitted. Further, once fitted, the locking portion 15 will not engage with the locking hole 22 of the flat plate portion 20 and will not easily come off. In particular, since the screw hole 16 is formed on the opposite side of the locking part 15 from the shaft support hole 13, when the screw 17 is tightened to the screw hole 16, the locking part 15 is connected to the flat plate part 20. The locking hole 22 formed on the side is more firmly locked into the locking hole 22. This ensures that the hinge member 10 is prevented from coming off from the flat plate portion 20.

In this way, after fitting the hinge member 10 to the flat plate portion 20, each screw hole 16 of this hinge member 10 is
At the same time, screw the screw 17 into the hinge member 1.
The pivot shaft 12 is inserted through the shaft support hole 13 of the hinge member 10 so that both ends of the pivot shaft 12 protrude from both sides of the hinge member 10.
Then, two other hinge members 10 are fitted to both ends of this pivot 12 in their respective shaft support holes 13 in an upside-down state. Each of the hinge members 10 fitted later is fitted to the end edge 21 of the flat plate part 20 and fixed with the screw 17, similarly to the hinge member 10 fitted first. Thereby, the flat plate parts 20 constituting the box, the lid, etc. can be easily and reliably connected.

Moreover, by using the hinges formed by these hinge members 10 for many years, each hinge member 10
If any of the hinge members 10 is damaged, just replace the damaged hinge member 10 with another hinge member 10, and the other undamaged hinge members 10 can continue to be used, which is extremely economical. It is.

(Example) FIG. 1 shows a state in which the edges 21 of a pair of flat plate parts 20, 20 constituting a box, a lid, etc. are connected using the hinge according to the present invention. A total of three hinge members 10 are used to connect the flat plate parts 20, 20.

Each hinge member 10 is integrally formed of a synthetic resin material such as plastic.
As shown in the drawings and FIG. 3, it includes a pair of arm portions 11 facing each other and a connecting portion 14 that connects the pair of arm portions 11 to each other. A pivot hole 13 for inserting the pivot 12 is provided in the center of the connecting portion 14.
is formed.

Furthermore, a locking portion 15 that is perpendicular to the arm portion 11 is integrally formed inside one of the pair of arm portions 11 . As shown in FIGS. 4 and 5, the locking portion 15 is formed in a cylindrical shape, and the height of the locking portion 15 increases from the end edge side of the arm portion 11 toward the connecting portion 14 side. It is formed to be high. Further, a pair of screw holes 16 facing each other are formed in the pair of arm portions 11 .

Of the pair of screw holes 16, one of the screw holes 16 is shaped like a saucer to hold the head of the screw, and the other screw hole 16 is shaped like a saucer to hold the head of the screw.
is a screw hole into which the threaded portion of the screw 17 is screwed. In this embodiment, the pair of screw holes 16 and the locking portion 15 are formed so that their center lines coincide.

Furthermore, in the above embodiment, an example was explained in which three hinge members 10 were used to form one hinge, but if the flat plate portions 20 to be connected are large, four hinge members 10 may be used. If the above hinge members 10 are used in succession, they can also be used as a hinge having desired strength.

In addition, in the hinge member 10 that is fitted to both ends of the pivot 12, the pivot 12 is prevented from coming off through the pivot hole 13.
It is best to make it a part of the Further, in the hinge member 10 located at the center, the pivot 12 inserted into the pivot hole 13 may be fixed.

(Effect of the invention) In summary, in the present invention, as exemplified in the above embodiment,
