Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to the improvement of a door check device suitable for automobiles.

[Prior Art] Conventionally, a door check device that regulates the opening/closing angle of an automobile door in stages has been proposed, for example, by
As disclosed in Japanese Patent No. 81917 and shown in FIG.
01, 101 are biasing members 105, 105 such as springs
The structure is such that it is strongly biased toward the control surfaces 107, 107 of the arm 103.

[Problems to be Solved by the Invention] In the check device having such a configuration, the guide member 101 includes the support member 109 and its storage portion 111.
A guide roller 113 is rotatably provided inside the case 115, and the guide rollers 113 are assembled inside the case 115 so as to face each other.

Therefore, when assembling, the guide roller 11
A pair of support members 109, 109 in which 3 is housed
and the supporting members 109, 109 and the biasing members 105, 105 arranged in series are compressed and held using a jig, and are simultaneously assembled into the case 115 in this held state. In this case, guide roller 1
13 is housed in a storage part 111 with a shallow bottom. Therefore, when the pair of support members 109, 109 are laid down or raised to face each other, the roller 113 falls off, making the work of butting the support members 109 very troublesome. Ta. For this purpose, grease is applied inside the housing portion 111, and the guide roller 113 is temporarily fixed using the viscosity of the grease.

Temporary fixation using the viscosity of grease is unstable and tends to fall off due to vibrations, making it an impediment to automation. For this purpose, a method of pivotally supporting the guide roller 113 on the support member 109 using a roller shaft has been considered, but this is not desirable because it increases the number of processing steps and takes time to assemble.

[Means for Solving the Problems] Therefore, the object of this invention is to provide a door check device that does not impair workability and can improve the number of assembly steps.

In order to achieve the above object, this invention includes a pair of opposing support members that rotatably store and hold a guide roller assembled in a case, and one of which has a storage portion that is open; A pair of biasing members biasing the support member and an arm having a control surface sandwiched by the guide roller are provided. A recessed portion having a diameter larger than the roller support portion is formed on both end faces of the roller support portion, and the recessed portion of the guide roller inserted from the open side of the storage portion is forcibly and loosely fitted into the roller support portion.

[Function] According to the door check device configured as described above, when setting the guide roller in the storage section, both ends of the guide roller are inserted from the open side and are forcibly fitted loosely into the roller support section of the storage section. Can be easily temporarily supported. As a result, workability is not impaired, and the guide roller does not fall off from the storage section, making automation easier. Further, since the guide roller in operation is supported by the storage section, it does not have any influence on the roller support section, and the roller support section only has a temporary supporting function.

[Embodiment] Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 6.

In the figure, reference numeral 1 indicates a door check device for an automobile, and the door check device 1 has a holding mechanism 3 and an arm 7 passing through a case 5 of the holding mechanism 3.

One end of the arm 7 is attached to a bracket 13 on the vehicle body 11 side.
The control surface 9 is pivotally connected 15 to the control surface 9 and has a raised portion 9a formed therein.

On the other hand, the holding mechanism 3 is attached to the door panel 1 of the door 17.
7a, a pair of biasing members 19, 19 housed in the case 5, and the biasing members 19, 19 biasing the control surfaces 9, 9 of the arm 7. A pair of guide members 2 that are in strong contact
1 and 21, and the biasing member 19 uses a coil spring.

The guide member 21 is composed of a support member 2 made of synthetic resin having a storage section 23 whose opposing surface side is open, and a guide roller 27 housed in the storage section 23 of the support member 25 . Guide roller 27
The guide roller 27 is formed into a hollow cylindrical shape by winding a stainless steel band plate into a roll shape and abutting both ends. It is rotatably supported.

Note that the guide roller 27 may be a seamless hollow pipe without abutting surface, or
It is also possible to use a cylindrical body as shown in FIG.
In the case of the guide roller 27 of this embodiment, roller support portions 29 protruding from the storage portion 23 are provided at both ends.
Recesses 31, 31 are formed which engage with 29 in a detachable manner. Note that 33 indicates a stopper provided on the free end side of the arm 7.

To explain the assembly procedure of the door check device configured in this way, the storage section 23 of the support member 25
Both ends of the guide roller 27 are forcibly pressed against the roller supports 29, 29. Since the roller support part 29 is made of synthetic resin, it is elastically deformed by pressure and comes to engage with both ends of the guide roller 27.

Next, the supporting members 25, 25 are attached to the guide roller 2.
7 and 27 face each other. In this case, the guide roller 27 is in a supported state and will not fall off, making the butting work easier.

Next, the biasing member 1 is connected in series with the supporting members 25, 25.
9 and 19 are held in a compressed state with a jig, and then inserted into the case 5. Next, arm 7
After one end of the arm 7 is inserted between the guide rollers 27 so as to pass through the window hole 5a of the case 5, the base cover 35 is attached.

[Effect of the invention] As explained above, in the door check device of the type in which the arm is held between the guide rollers set in the storage section, the roller support section and the recessed section allow the arm to be guided from the open side to the storage section. The guide roller can be temporarily supported by a simple operation of forcibly inserting the roller. For this reason, workability is not impaired, and moreover, the guide rollers can be maintained in a reliable temporary supported state, making automation possible. Further, since no load is applied to the roller support portion, there is no need to consider strength, so there is no restriction on the material, and it is also very favorable in terms of workability.
