Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile door hinge equipped with a door check mechanism.

Conventional door hinges are shown in Figure 1 a, b, c.
As shown in the figure, a fixed hinge member 1 fixed to the vehicle body side and a rotating hinge member 2 fixed to the door side are rotatably connected by a hinge pin 3, and the fixed hinge member 1 and the rotating hinge member 2 are connected rotatably by a hinge pin 3. The relative movement is regulated by the check mechanism 4, which has a cam member 41 pivotably attached to the side of the rotating hinge member 2, and a cam surface 42 of the cam member 41 on the fixed hinge member 1. A compression spring 44 is interposed between the base 21 of the rotating member 2 and the swinging tip of the cam member 41, so that the cam surface 42
A so-called cam roller type is known in which the roller 43 is pressed against the roller 43, and the roller 43 is moved above the cam surface 42 as the fixed hinge member 1 and the rotating hinge member 2 move relative to each other as the door opens and closes. The cam surface 42 rotates to perform a door check function at a predetermined position according to the shape of the cam surface 42. Examples of such conventional techniques include, for example, Japanese Utility Model Publication No. 41216/1983.

However, in conventional door hinges, the compression spring 43 is assembled by compressing it sufficiently and then inserting it into a predetermined position to apply a preload. Once disassembled, reassembly is not easy, so it is practically impossible to remove the hinge pin 3, separate the door from the vehicle body, and then reattach it to the vehicle body after assembly. Further, there are many restrictions on the mounting positions of the cam member 41 and the roller 43, making it difficult to obtain good check performance.

The present invention solves the above problems and provides a door hinge that is easy to assemble and easy to separate and reassemble.The present invention is a door hinge that is easy to assemble, separate, and reassemble. To provide a door hinge that performs a check action by being elastically clamped.

The present invention will be explained below with reference to embodiments shown in the drawings. Note that the same parts are given the same numbers.

As shown in FIGS. 2a, b, and c, the door hinge according to the present invention has a fixed hinge member 1 fixed to the vehicle body side and a rotating hinge member 2 fixed to the door side, which can be rotated by a hinge pin 3. They are connected to each other and equipped with a check mechanism 5 on the side. The check mechanism 5 includes an arm member 51 having one end pivotally connected to the side of the rotation hinge member 2.
and an arm member 51 fixed to the fixed hinge member 1.
It consists of a holding member 52 that holds the .

Third regarding the arm member 51 and the holding member 52
To explain in detail with the drawings, the arm member 51 has a long hole 53 bored in the longitudinal direction at the center, a flat surface 54 from the pivot end to a position corresponding to a predetermined door opening position, and further toward the tip. Protrusions 55 are continuously formed on both sides of the elongated hole 53. Holding member 52
is a disc spring 56 so as to sandwich the arm member 51.
A pair of projections 5 slidingly contact the arm member 51.
7 are disposed on both sides of the arm member 51, and are screwed onto the fixed hinge member 1 with bolts 59, so that the sliding force can be adjusted by tightening torque. That is, the bolt 59 is a fixed member to which the slider 58 is attached and has a flange, and between the flange and the slider 58 on one side, and between the fixed hinge member 1 and the other side. Slider 5
A disc spring 56, which is an elastic member that biases the slider 58, is interposed between the slider 8 and the slider 58. Note that 60 is the long hole 53
This is a claw that fits into the slider 58 to keep the direction of the slider 58 constant. In other embodiments, the protrusions 57 may be provided radially to eliminate the need for regulating the direction of the slider 58. In still other embodiments, the arm member 51 is made to have elasticity without relying on the disc spring 56. Good as a component,
The elongated hole 53 may not be provided and it may be fitted between the holding members 52 and held therebetween.

To explain the function of the door hinge according to the present invention, the arm member 51 and the holding member 52 slide against each other as the door is moved from the closed state shown in FIG. 2B to the opened state shown in FIG. 4. At the beginning of opening the door, slider 58
Since it is on the flat surface 54, there is little influence on the door opening of the check mechanism 5. As the door opens further and reaches the raised part 55, the opening resistance increases, and as the door opens further and reaches the raised part 55, the door opening resistance increases.
When the door reaches this point, no matter which direction you try to rotate it, the operating resistance increases and the door stops stably at that position. If you open the door further, you will see the next protrusion 5.
5, the door is held stopped by the raised portion 55 and the full opening stopper. At this time, since the slider 58 is on the plane of the tip of the arm member 51, unlike on the inclined surface of the raised portion 55, no door opening/closing force is generated.

As can be seen in FIGS. 2 and 4, the arm member 51 is located on the side of the door hinge, that is, within the mounting space of the door hinge formed between the door and the vehicle body.

When the door is opened and closed, the arm member 51 swings within the installation space of the door hinge formed between the door and the vehicle body, and does not interfere with other parts.
No opening is provided at any part of the body for passing the free end of the body.

According to the present invention, the check mechanism functions extremely stably and is extremely easy to assemble. Furthermore, the position or shape of the raised portion can be changed as appropriate to optimize the operational feel. Even if the hinge pin is removed, no problem will occur because the preload of elastic force will not affect the hinge pin portion. Therefore, the door can be easily separated from the vehicle body for single assembly. The arm member and the holding member can be slid and removed by opening the distal end side of the elongated hole formed in the arm member. Similar results can be obtained even if the arm member is made into a single bar shape, making it possible to provide a door hinge with significantly improved functionality and operational performance compared to conventional door hinges.

In addition, the arm member swings only within the mounting space of the door hinge, does not interfere with other parts, and does not require an opening for insertion, allowing dust and water to enter the cross-sectional space of the vehicle body or door. There's nothing to do,
Moreover, the door hinge itself is miniaturized, and combined with the above-mentioned ease of assembly, the door hinge becomes easy to handle.
