Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure improvement of a hinge, in particular, a combination of a kind of pigeon tail seat and pigeon tail tank and a spring built in the pigeon tail tank, which is easy to assemble, and the cost is low because the constituent parts are simple and safe. It is highly practical and highly practical.

[0002]

[Prior art]

 Hinges are commonly used, for example, furniture chests, doors, etc., all of which require hinges to be attached, which makes us very convenient and is very pleased by the general public. After many years of improvement, hinges have now evolved from ordinary simple hinges to various types of hinges that can be opened and closed automatically.

[0003]

[Problems to be solved by the device]

 However, the structure of these hinges that automatically open and close is considerably complicated, and the cost is considerably high. Further, there are drawbacks such that it is complicated to assemble and takes a lot of time.

[0004]

[Means for Solving the Problems]

 The main object of the present invention is to provide a hinge structure which is composed of a kind of pigeon pit and a pigeon pedestal, is easy to assemble and is low in manufacturing cost. Another object of the present invention is to provide a pigeon seat hinge characterized by having a spring built in a kind of pigeon tail tank, which is safe and can be automatically opened and closed.

[0005]

【Example】

 Hereinafter, preferred embodiments will be described in detail with reference to the drawings. As shown in FIG. 1, the pigeon hinge of the present invention includes a pigeon tail 1, a pigeon tail tank 2, a mounting plate 3, a spring 4 and a pin 5, of which the front of the pigeon tail 1 is

[0006]

[Equation 3]

It has a mold shape, and side plates 11 and 12 extend to the left and right respectively. Mounting holes 111 and 121 are provided on the side plates 11 and 12, respectively, and an end plate 13 is provided at the rear end of the dovetail 1. Front of pigeon tank 2

[0008]

[Equation 4]

It is shaped so that it fits inside the pigeon pedestal 1. A single cylinder 21 is provided at the tip of the dovetail seat 1, a mounting hole 31 is provided in the mounting plate 3, and one end of the dovetail seat 1 is formed into two cylinders 32 which are wound downward and have an appropriate interval. The cylinder 21 at the tip of the dovetail tank 2 is fitted between the two cylinders 32 of the mounting plate 3, and pins are inserted into these cylinders to pivotally connect them. The spring 4 hooks and fixes the tip hook 41 at an appropriate position on the front end of the dovetail tub 2, and hooks and fixes the rear end hook 42 on the rear end plate 13 of the dovetail seat 1.

As shown in FIGS. 2 and 3, when the pigeon seat hinge of the present invention is actually used, the mounting plate 3 is mounted on the furniture main body A (for example, a pillar of a gate or an inner plate of a closet). , Pigeon tail 1 is installed on furniture door B. At the time of mounting, if the mounting plate 3 is orientated, the spring 4 is mounted in the pigeon tail tank 2, the pigeon tail seat 1 is assembled, and then the pin 21 is inserted between the cylinders 32 so that the hinge 5 can be assembled. Once completed, and by selecting an appropriate mounting method (screw fixing or welding) and mounting and fixing the mounting holes 111 and 121, the purpose of localization can be achieved. It is not necessary to measure the position accurately for assembly and mounting, and it is simple A quick effect can be mentioned.

Also, as shown in FIG. 4, when a force is applied to the door B after the dovetail hinge of the present invention is attached and positioned, the dovetail 1 moves according to the door B by the action of the spring 4 and releases the hand. Then the spring 4 contracts and the door B automatically closes.

[0012]

[Effect of device]

 Next, the particularly excellent points of the present invention will be summarized. 1. The component parts of the present invention are extremely simple, and the cost is extremely low as they consist of only five simple parts. 2. Assembling the dovetail tank and dovetail seat is a dovetail type

[0013]

[Equation 5]

Because of this, there is no danger of falling off, the localization is reliable, and the assembly is quick. 3. The automatic opening and closing of the door is achieved by the spring built into the pigtail tank, so the operating time is too long and there is no danger to the user if the spring causes elastic fatigue or breaks, it is extremely safe. Is. 4. When the door is fully open, it forms 180 degrees with the furniture or gate frame and opens completely, so there is no blind spot and it is convenient for taking things out. There are no gaps, so there is no fear of getting your fingers caught and it is safe. Is.

5. Since there is a mounting hole for mounting, it is not necessary to carve a groove and the mounting method can be selected depending on the material, if it is wood it is mounted with screws, if it is metal it can be mounted by welding. Since it is good, there is no limitation due to the material and it is highly practical. 6. It is not necessary to precisely measure the dimensional position during assembly or installation, and assembly and installation is easy and quick.

As can be seen from the above characteristics, the present invention has an excellent effect, the cost is less than half that of the conventional automatic opening / closing hinge, and the economical utility is extremely high. It is a good article.
