Abstract

PURPOSE:To increase the soft feeling with a gear shift lever of a car by fitting a lower lever into an upper lever for said shift lever via a vibration proof rubber containing circular projections. CONSTITUTION:A lower lever 3 is put fixedly into an upper lever 1 via an approximately cylindrical vibration proof rubber 5 containing circular projections 5a-5d on its outer circumference surface. Thus both levers 1 and 3 are elastically connected to each other. In such a constitution, the operating power applied to the lever 1 is first transmitted to the lever 3 via the projections 5b and 5c only. As a result, the extremely soft operating feeling is secured. When the larger power is applied to the lever 1, an inside wall surface 1a of the lever 1 touches the projections 5a and 5d positioned at the upper and lower end parts of the rubber 5. Thus both projections 5a and 5d function as stoppers to prevent the extreme bend of the rubber 5 and therefore no excessive load is applied to the rubber 5. Thus both the durability and the rigidity are increased for the rubber 5.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gear shift lever for a vehicle, and more particularly to a lever structure that provides a softer feel when operating the lever.

Prior Art Regarding this type of gear shift lever, for example, Japanese Patent Application No. 1986-
233340, as shown in FIG. 6, a plurality of annular projections 2a, 2 are provided on the outer peripheral surface of an annular upper lever l.
The lower lever 3 is inserted and fixed through the substantially cylindrical vibration isolating rubber 2 in which the vibration isolating rubber 2 is formed, and the lower lever 3 located at the portion corresponding to the upper end 2d and lower end 2e of the vibration isolating rubber 2 has a large diameter. The large diameter portions 3a, 3 are formed by forming the large diameter portions 3a, 3b.
A configuration is disclosed in which the rubber thickness of the vibration isolating rubber 2 located on the surface of b is reduced to locally increase the hardness.

According to such a configuration, when an operating force is applied to the upper lever l, the upper end 2d and the lower end 2e of the vibration isolating rubber 2
comes into contact with the inner periphery of the upper lever 1 to exert a stopper effect, prevent extreme deflection of the vibration isolating rubber 2, and increase the rigidity on the knob to maintain a hard moderation feeling when operating the gear shift lever. becomes possible.

Furthermore, as shown in FIG. 7, Japanese Patent Application No. 58-232093 discloses a substantially cylindrical barrier having a plurality of annular protrusions 2a, 2b, 2c, and 2f formed on the outer peripheral surface of the annular upper lever l. The lower lever 3 is inserted and fixed via the vibrating rubber 2, and is placed in the vicinity of the lower end of the upper lever l to either one of the upper lever l or the lower lever 3, without contacting the other lever under normal conditions. A configuration in which a ring-shaped stopper 4 is fixed is disclosed. Even with such a configuration, when an operating force is applied to the upper lever l, the stopper 4 comes into contact with either the upper lever l or the lower lever 2, preventing extreme deflection of the vibration isolating rubber 2. Similarly, by increasing the stiffness above the knob, it is possible to maintain a hard moderation feel when operating the gear shift lever.

Problem to be Solved by the Invention However, in any case, in such a conventional gear shift lever, the vibration isolating rubber 2 satisfies the requirements for both vibration damping and sound insulation properties, and the gear shift lever is The main focus is to obtain a shift feeling that does not feel strange when operating the lever, and when focusing on the shift feeling mentioned above, the hardness of the anti-vibration rubber is locally increased and the stopper is fixed. It is characterized by increased rigidity to provide a firmer feel when operating the gear shift lever. On the other hand, in response to recent demands from users, there is a demand for a gear shift lever that eliminates the hard moderation feel when operating the gear shift lever, gives a flexible operating feel, and has a soft and luxurious feel. In order to meet such demands, it is conceivable to increase the thickness of the vibration isolating rubber 2, but such a measure would require increasing the diameter of the gear shift lever itself.
There is a problem in that it leads to an increase in the size of parts and an increase in cost.

Therefore, the present invention solves these problems with conventional gear shift levers, satisfies the requirements for both vibration and sound insulation properties, and eliminates the hard feeling of moderation when operating the gear shift lever, thereby providing flexible operation. The object of the present invention is to provide a gear shift lever that has a soft and luxurious shift feeling.

Means for Solving the Problems In order to achieve the above object, the present invention provides a lower lever for a tubular upper lever via a substantially cylindrical anti-vibration rubber having a plurality of annular protrusions formed on the outer peripheral surface. By inserting and fixing, in a gear shift lever formed by elastically connecting the upper lever and the lower lever, a gap is formed between the annular protrusion located at the upper and lower ends of the vibration isolating rubber and the upper lever. On the other hand, the gear shift lever structure is such that the distance between the annular protrusions located in the middle part of the vibration isolating rubber is shortened to the minimum necessary dimension to maintain the stiffness on the knob of the upper lever.

When an operating force is applied to the upper operating lever, this operating force is first transmitted to the lower lever only through the annular protrusion located in the middle of the vibration isolating rubber, so an extremely soft operating feeling can be obtained. In addition, when a larger force is applied to the upper lever, the annular protrusions located at the upper and lower ends of the vibration isolating rubber act as stoppers, preventing the vibration isolating rubber from being excessively bent. No excessive load is applied to the knob, increasing durability and increasing the rigidity on the knob. Even during the above operation, since the hardness of the annular projection is not high, the upper lever can maintain a soft operating feeling.

Further, as shown in FIG. 3, the distance along the longitudinal direction of the annular projections 5b and 5c formed on the vibration isolating rubber 5 is similar to the distance L' of the conventional annular projections 2b and 2c (FIG. 7). One of its characteristics is that it is shortened compared to . That is, the distance t between the annular protrusions 5b and 5c + 7) is the upper lever l.
The knob has been shortened to the minimum dimensions necessary to maintain rigidity.

According to such a configuration, when an operating force is applied to the upper lever l, this operating force is first transmitted to the lower lever 3 only via the annular protrusions 5b and 5c of the anti-vibration rubber 5, so that the operating force is extremely soft. You can get a feeling of operation. Further, when a larger force is applied to the upper lever l, the inner wall surface 1a of the upper lever l comes into contact with the annular protrusions 5a and 5d located at the upper and lower ends of the vibration isolating rubber 5, and the annular protrusions 5a , 5d act as stoppers, preventing extreme deflection of the vibration isolating rubber 5, preventing excessive load from being applied to the vibration isolating rubber 5, increasing durability, and keeping the stiffness on the knob to a predetermined level.
