Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a knob structure for manually operating a locking/unlocking mechanism of an automobile door lock device from inside the vehicle.

Conventionally, this type of knob structure consists of a knob body and a decorative frame provided on the inner plate of the door that movably holds the knob body. However, if there is a gap between the fitting parts of the two, the knob may become loose when the vehicle is running. The main body is vibrated, which hits the decorative frame and generates rattling noise. As a countermeasure against this problem, a structure which prevents rattling noise as shown in FIG. 1 is generally well known, as disclosed in Japanese Utility Model Publication No. 47139/1983.

In other words, the inner panel A forming the inner panel of the door
A cylindrical knob body is provided with a tapered skirt portion C integrally attached to a cylindrical decorative frame B fitted to the upper end, and is held movably up and down within the decorative frame B. By pressing against the side wall surface of D, deflection is elastically suppressed, and rattling noise is prevented from occurring from the mutually fitted portions.

However, although the conventional knob structure described above is effective against the rattling noise of the knob body, it cannot suppress the rattling of the decorative frame, and the side wall of the knob body has An indentation was left along the lock, and in the unlocked state, this indentation was exposed from the decorative frame body, making the exterior appearance unsightly.

The present invention was developed in view of the current situation, and includes a knob structure in which the knob body for locking and unlocking the door lock device is movably held by a decorative frame fixed to the door trim. , at a sliding surface of the knob body with the decorative frame and at a position that is not exposed from the decorative frame within the movement range for locking and unlocking;
A first tongue piece that comes into elastic contact with the decorative frame body is integrally formed to protrude, and a first tongue piece is provided on the surface of the knob body facing the inner panel and at a position orthogonal to the first tongue piece. To provide a knob structure for a door lock device for an automobile, which integrally projects a second tongue piece that makes elastic contact with the knob body, prevents rattling noise of the knob body and the decorative frame body, and improves the appearance. It is something.

Embodiments of the present invention will be described below based on the accompanying drawings. In FIGS. 2 and 3, 1 is a car door, and the inner panel 2 of the door 1 is composed of an inner panel 3 and a trim 4 that covers the entire surface and upper edge of the inner side of the vehicle. A glass 5 is provided to be movable up and down.

The opening 4a extends from the upper edge of the trim 4 to the side.
A decorative frame body 6 is fitted into this hole.

The decorative frame body 6 has a pair of claws 6a, 6a that engage with the upper and lower edges of the opening 4a, and an upper vertical hole 6c and a side horizontal hole 6d formed by a partition wall 6b provided in the middle. is provided.

Referring also to FIGS. 4 to 6, reference numeral 7 denotes a knob body integrally formed from a synthetic resin material, which includes a rectangular cylindrical base 7a that is open at the bottom and a hole in the center of the front surface of the base 7a. It consists of an unlocking protrusion 7b with a substantially triangular cross section, a prismatic locking protrusion 7c formed above the base 7a, and an engagement hole 7d bored inside the base 7a. ing.

Further, grooves 7e, 7e are provided along the longitudinal direction on both side walls of the base 7a, and first tongues 7f, 7f having elasticity that bulge in the left-right direction in FIG. Further, in the middle part of the rear surface, second tongue pieces 7g, 7 having elasticity that expand and extend to the left and right at the rear are provided.
g are provided respectively.

Reference numeral 8 denotes a connecting rod, and a male threaded portion 8a is formed at the upper end, and this male threaded portion 8a is forcibly screwed into the engagement hole 7d of the knob body 7 by screwing it in while rotating relatively. There is.

The locking protrusion 7c of the knob body 7 attached to the connecting rod 8 is inserted into the vertical hole 6c of the decorative frame body 6 from below, and the intermediate unlocking protrusion 7b is inserted into the horizontal hole 6d from the side. The knob body 7 is loosely fitted, and the knob body 7 is held by the decorative frame body 6 so as to be slidable in the vertical direction.

Further, the first tongue piece 7f provided on the side wall portion of the knob body 7 is attached in a state in which it is in sliding contact with the side walls 6e, 6e which are continuously formed below the vertical hole 6c of the decorative frame body 6. , the vibration in the left and right direction is elastically suppressed, and the second tongue piece 7g
At a position orthogonal to the tongue piece 7f, and at the inner panel 3
It is attached so that it is in sliding contact with the inside surface of the vehicle, and its vibration in the longitudinal direction (thickness direction of the door) is elastically suppressed. This is pressed so as to close the side end faces. Therefore, the lower end claw portion 6a of the decorative frame 6 is also pressed against the trim 4, and the wobbling of the decorative frame 6 is also suppressed.

The lower end (not shown) of the connecting rod 8 is connected to a locking/unlocking mechanism of a door lock device (not shown), and the knob body 7
It is locked when the locking protrusion 7c is pushed down,
Further, the lock can be unlocked by hooking a finger on the lower surface of the unlocking protrusion 7b and pulling it up.

When the knob body 7 moves up and down, the first and second
The tongue pieces 7f and 7g are the decorative frame body 6 and the inner panel 3
Since it moves while being in pressure contact with the knob body 7, the wobbling in the longitudinal and lateral directions of the knob body 7 is elastically suppressed, and the wobbling of the decorative frame body 6 in the longitudinal direction in FIG. 4 is elastically suppressed. Even if these are sometimes vibrated, no rattling noise is generated. Also,
Each of the tongue pieces 7f and 7g is formed at an appropriate lower position of the knob body 7 so that the tongue pieces 7f and 7g do not protrude from the decorative frame body 6 and become unsightly.

As detailed above, according to the present invention, since the knob body is provided with a tongue piece that makes elastic contact with the decorative frame body and the inner panel, it is possible to prevent rattling noise of the knob body and the decorative frame body, and moreover, it is possible to prevent the knob body and the decorative frame body from rattling. The impressions formed during sliding on the structure are prevented from being exposed and becoming unsightly, and the appearance is improved. Furthermore, there are fewer restrictions on the shape of the decorative frame, and the degree of freedom in design can be improved, making it extremely practical.
