Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge for connecting, for example, a swing of a truck to a body.

[0002]

2. Description of the Related Art Generally, a first blade having a pair of first knuckles penetrating a connecting shaft and a second blade having a second knuckle fitted between the first knuckles of the first blade and penetrating the connecting shaft. Hinges with are known. In this type, it is common to penetrate the connecting shaft between a pair of first knuckle and second knuckle, and then fix the connecting shaft to the second knuckle of the second blade using a stop pin such as a spring pin. It is.

[0003]

However, when the connecting shaft is fixed by using a spring pin or the like, it is necessary to make a hole in each of the connecting shaft and the second knuckle, and to connect them. In some cases, it is necessary to connect the pin holes after aligning them. In particular, when a large number of hinges are manufactured, there is a problem that the increase in the number of operations increases the manufacturing cost.

In the case of a hinge for a truck, the outer ends of the pair of first knuckles or the ends of the connecting shaft projecting therefrom must be formed in a curved surface or cut at an angle of 45 ° or more. There are safety restrictions.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, and to connect the first blade and the second blade using a connection shaft without using any stop pin such as a spring pin. It is to provide a hinge that can be used.

[0006]

According to the first aspect of the present invention, there is provided a first blade having a pair of first knuckles through which a connecting shaft passes, and the first shaft being fitted between the first knuckles of the first blade. A hinge having a second knuckle having a second knuckle penetrating therethrough, wherein a pair of fixing tools for supporting both ends of the connection shaft are provided outside the pair of first knuckles provided on the first blade. Is what you do.

According to a second aspect of the present invention, in the first aspect, the length of the connecting shaft is set such that both ends of the connecting shaft are located inside the outer ends of the pair of first knuckles. In addition, both ends of the connecting shaft are supported by a pair of fixing tools fixed to the first blade.

According to these inventions, since the first blade and the second blade are connected without using any spring pin or the like, the work required for connection is simplified, and the manufacturing cost can be reduced as compared with the conventional one. it can.

According to a third aspect of the present invention, in the first or second aspect, the outer periphery of the pair of fixing members is formed by a curved surface.

According to the third aspect of the present invention, since the first blade and the second blade can be connected without using any spring pin or the like, the work required for connection is simplified and the manufacturing cost is reduced. And a curved surface is formed on the outer periphery of each of the pair of fixtures, so that safety restrictions can be cleared.

According to a fourth aspect of the present invention, in the first aspect, the first blade and the second blade are made of an aluminum alloy, and the fixing member is made of a resin. It is characterized by having been made.

According to the fourth aspect of the invention, since the hinge is manufactured from an aluminum alloy, a resin, or the like, the weight of the hinge can be reduced.

[0013]

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a truck body. A hinge 5 is connected to the body 1 with a plurality of hinges 3 by screws 7 and 9.

The hinge 3 has a first blade 10 and a second blade 20 as shown in FIGS. 2 and 3, which are made of lightweight aluminum. The first blade 10 is integrally formed with a pair of cylindrical first knuckles 13 in addition to the two screw holes 11. In addition to the three screw holes 21, a cylindrical second knuckle 23 fitted between the first knuckles 13 of the first blade 10 is formed integrally with the second blade 20. A connecting shaft 30 made of stainless steel penetrates between the pair of the first knuckle 13 and the second knuckle 23.

Conventionally, after the connecting shaft 30 is passed between the pair of the first knuckle 13 and the second knuckle 23,
Generally, the connecting shaft 30 is fixed to the second knuckle 23 using a stop pin (not shown) such as a spring pin.

In this embodiment, the length of the connecting shaft 30 is set to a length L which does not protrude from the outer ends 13 a of the pair of first knuckles 13, and both ends 30 a of the connecting shaft 30 are fixed to the first blade 10. It is supported by contacting a pair of resin fixtures 40 to be formed. As shown in FIG. 4, a pin 40a protrudes from the fixture 40, and
a is press-fitted into a pin receiving hole 10 a provided in the first blade 10, whereby the pair of fixing tools 40 are fixed to the first blade 10. Note that the fixture 40 may be fixed to the first blade 10 with an adhesive or the like. An arcuate curved surface 40b is formed on the outer periphery of each of the fixing members 40.

According to this embodiment, the first blade 10 and the second blade 10 can be connected using the connection shaft 30 without using any spring pin or the like.

In the case of a hinge for a truck, the outer ends 13a of the pair of first knuckles 13 or the ends of the connecting shafts 40 protruding therefrom are formed into a curved surface or have an angle of 4 degrees.
There is a safety restriction that it must be cut to 5 ° or more. In this embodiment, since the outer circumferences of the pair of fixtures 40 are each formed by the curved surface 40b, this safety constraint can be sufficiently cleared.

FIG. 5 shows another embodiment. Compared to FIG. 1, the truck according to the embodiment of FIG.
The tilt 5 is arranged in the same plane. Therefore, the shape of the second blade 20 differs accordingly. In other words, the second blade 20 has a step 2 at a portion avoiding a part 5a of the swing 5
5 are provided.

Since other configurations are the same also in this embodiment, the first blade 10 and the second blade 10 can be connected without using any spring pin or the like, and safety restrictions are sufficiently reduced. Can be cleared.

[0022]

According to the first to fourth aspects of the present invention, since the first blade and the second blade can be connected without using any spring pin or the like, the operation is simplified.
The manufacturing cost can be reduced, and if the curved surfaces are formed on the outer periphery of the pair of fixtures, safety restrictions can be sufficiently cleared. Can be achieved.
