Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an opener for opening and closing a vehicle opening/closing body (such as a trunk) from inside the vehicle.

(Prior art) The conventional opener of this type was Utility Model 59-57669.
The one shown in Publication No. 1 is known. this is,
Multiple iron plate levers were rotatably caulked to the base using pins.

(Problems to be Solved by the Invention) However, since the opener having the above-mentioned configuration is fixed by caulking with a pin, it is difficult to assemble and the cost increases. Also, due to dimensional accuracy, play is likely to occur between the pin and the lever, and this play causes the pin to swing around the caulked part, and when the caulked part of the pin loosens, vibration occurs between the pin and lever and between the base and lever. A noise was generated, and if the caulked portion became too loose, there was a risk that the lever would come off the base.

Therefore, the technical object of the present invention is to provide an inexpensive opener that makes it easy to assemble the lever, and also to eliminate the backlash caused by the swinging of the pin.

[Structure of the idea]

(Means for Solving the Problems) The technical means taken by the present invention to solve the above technical problem is that a base integrally formed with a cylindrical protrusion engages with the protrusion. a lever integrally formed with an engaging part and a holding part that is inserted into the protrusion and is engaged and fixed to the base;
The lever is rotatably held on the base by the engaging portion and the holding portion.

(Operation) The above technical means operates as follows. The lever does not require a pin because it is rotatably fixed to the base by an engaging part that engages with a protrusion formed integrally with the base and a holding part that is inserted into the protrusion and fixed to the base. The lever can be fixed to the base without having to be attached to the base, the lever can be easily assembled, and an inexpensive opener can be provided. Further, since the holding part of the lever is inserted and fixed into the protruding part of the base, the holding part does not swing, thereby preventing the occurrence of backlash, and also preventing the lever from coming off from the base.

(Example) An example embodying the technical means of the present invention will be described based on the accompanying drawings.

As shown in FIG. 1, the opener 1 includes a base 10 fixed in a vehicle interior (not shown) and a trunk lever 20 rotatably held on the base 10.
and a fuel lever 30. Claw portions 2 and 3 are formed on the base 10. A spring 4 is attached between the pawl portion 2 and a pawl portion (not shown) formed on the trunk lever 20. This spring 4 is always biased so that the trunk lever 20 is in its initial position, that is, closes the trunk provided on the vehicle body (not shown). Further, a spring 6 is installed between the claw portion 3 and the claw portion 5 formed on the fuel lever 30. This spring 6
The fuel lever 30 is always biased to the initial position, that is, to close the fuel provided on the vehicle body (not shown).

As shown in FIG. 2, the base 10 is integrally formed with a cylindrical protrusion 11 that penetrates the base 10. A shoulder portion 12 that protrudes in the radial direction is integrally formed at the lower end of the protrusion 11 . Further, an annular groove 13 is formed in the base 10 along the outer periphery of the protrusion 11 . A through hole 21 is provided in the trunk lever 20. This through hole 21 has the same diameter as the outer periphery of the protrusion 11 and is coaxial with the protrusion 11 . Furthermore, trunk lever 20
An annular protrusion 23 that is flush with the outer circumferential surface 21 a of the through hole 21 and engages with the annular groove 13 of the base 10 is provided at the annular protrusion 23 . The fuel lever 30 is integrally formed with a holding part 31 that is inserted into the protrusion 11 coaxially with the protrusion 11 . This holding part 3
A claw portion 32 that engages with the shoulder portion 12 is integrally formed at the tip of the shoulder portion 1 . Furthermore, a slit 33 is provided approximately at the center of the tip of the holding portion 31. or,
An annular groove 34 is formed in the fuel lever 30 along the outer periphery of the holding portion 31.

Base 10 and trunk lever 2 configured as described above
0 and the fuel lever 30 are assembled as follows.

As shown in FIG. 2, the trunk lever 20 is made by inserting the protrusion 11 of the base 10 into the through hole 21, and then engaging the annular groove 13 with the annular protrusion 23 to rotate the trunk lever 20 toward the base 10. Holds possible. Further, the fuel lever 30 inserts the holding portion 31 into the protruding portion 11, and further inserts the holding portion 31 into the protruding portion 1.
The trunk lever 20 is rotatably held on the base 10 by engaging the tip of the trunk lever 20 with the annular groove 34.
Further, a claw portion 32 formed at the tip of the holding portion 31 of the fuel lever 30 engages with the shoulder portion 12 of the base 10 to prevent the fuel lever 30 from coming off the base 10. As a result, the trunk lever 20 is connected to the fuel lever 30 and the base 1.
It is clamped between the 0 and 0 to prevent it from coming off. Further, a mountain-shaped protrusion 25 is formed on the sliding surface 24 of the trunk lever 20 between the base 10 and the trunk lever 20. This reduces the sliding resistance of the trunk lever 20, thereby reducing backlash in the direction in which the trunk lever 20 is removed. Furthermore,
A mountain-shaped protrusion 36 is formed on a sliding surface 35 of the fuel lever 30 between the trunk lever 20 and the fuel lever 30. Thereby, the sliding resistance of the fuel lever 30 is reduced, and the backlash of the fuel lever 30 in the withdrawal direction is reduced.

Since the base 10, the trunk lever 20, and the fuel lever 30 are assembled as described above, the engagement between the protrusion 11 and the annular groove 34 and the engagement between the pawl 32 and the shoulder 12 leads to the release direction. This prevents rattling. Furthermore, the sliding contact between the outer circumferential surface 11a of the protruding portion 11 and the side surface 34a of the annular groove 34 and the sliding contact between the side surface 12a of the shoulder portion 12 and the side surface 32a of the claw portion 32 prevents the holding portion 31 from swinging. So, the claw part 32
The engagement between the trunk lever 2 and the shoulder portion 12 becomes loose, and the trunk lever 2
0 and the fuel lever 30 prevent the base 10 from coming off, and also prevent the fuel lever 30 from rattling in the radial direction. trunk lever 20
is held between the fuel lever 30 and the base 10, which prevents the trunk lever 20 from wobbling in the removal direction, and prevents sliding contact between the side surface 23a of the annular protrusion 23 and the side surface 13a of the annular groove 13, and the side surface of the through hole 21. The sliding contact between the trunk lever 21a and the outer circumferential surface 11a of the protrusion 11 prevents the trunk lever 20 from rattling in the radial direction. In addition, since the holding part 31 is inserted into the protruding part 11, excessive load when the trunk lever 20 or fuel lever 30 is activated is applied to the protruding part 11 and not to the holding part 31. It can be made smaller. Further, the contact between the side surface 13b of the annular groove 13 and the side surface 23b of the annular projection 23 causes damage inside the base 10 before the projection 11 is deformed and destroyed due to the excessive load applied to the projection 11 when the trunk lever 20 is operated. distributed to This allows the thickness of the protrusion 11 to be reduced. Based on the above
0. Trunk lever 20 and fuel lever 3
0 does not require great strength, so it can be made of resin, and the opener 1 can be made lighter.

FIG. 3 shows a modified embodiment. This is the case when the trunk lever 20 is removed and only the fuel lever 30 is used. As shown in FIG. 3, the fuel lever 30 is integrally formed with a pawl 42 and a slit 43 that are inserted into the protrusion 11 coaxially with the protrusion 11 and engage with the shoulder 12 at the tip. A protrusion 41 is integrally formed. Further, the fuel lever 30 includes an annular groove 44 along the outer periphery of the protrusion 41 that engages with the protrusion 11, and an annular protrusion that is flush with the side surface 44a of the annular groove 44 and engages with the annular groove 13 of the base 10. The portion 45 is integrally formed.

The opener having the above-described structure also eliminates backlash in the withdrawal direction and the radial direction, and can be made of resin, making it possible to reduce the weight of the opener 1.

[Effects of the invention] The present invention has a base integrally formed with a cylindrical protrusion, and a holding part that is inserted into the protrusion and is engaged and fixed to the base. and a lever integrally formed with the lever, and the lever is rotatably held on the base by the engaging part and the holding part, so the lever can be attached to the base without the need for a pin. can be fixed to, and can be easily assembled.
