Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement of a wire operation lever used for a heater control device or the like of an automobile.

(Prior Art) A wire operation lever of this type is rotatably attached to a base member, a wire is attached to a wire attachment hole, and an operation knob is reciprocally moved to remotely operate an operated object via the wire. To do. The wire is composed of a tubular outer one end of which is fixed to a base member, and an inner slidably inserted into the outer, and a tip of the inner protruding from the outer is attached to a mounting hole provided in a wire operation lever. It is designed to be inserted and attached. When the inner of this wire is pushed into the outer by the operating lever, the applicant of the present application has proposed to the base member in Japanese Patent Application No. 61-98541 to prevent the inner protruding from the fixed end of the outer from buckling. It is proposed to provide a buckling prevention wall.

(Problems to be solved by the invention) However, when the buckling prevention wall is provided on the base member, the existence of the buckling prevention wall becomes an obstacle when arranging other members, and particularly, the operation knob is In the case where the provided first lever and the second lever that is interlocked with the first lever are provided, it is extremely difficult to set the position of the buckling prevention wall and the wire, and the like. There were various restrictions on the arrangement and installation of the.

The present invention has been made in view of the above problems, and an object thereof is to provide a wire operation lever capable of preventing the buckling of a wire without providing a buckling prevention wall on the base.

(Means for Solving the Problems) In order to solve the above problems, a wire operation lever of the present invention comprises a first lever that is rotatably attached to a base member and has an operation knob at one end, and an outer and an inner. A second lever pivotally attached to the base member, and a second lever that rotates in conjunction with the rotation of the first lever. A link connecting the first lever and the second lever as much as possible, and a buckling formed on the first lever so as to cover the inner that is pulled out from the side where the inner is inserted into the wire mounting hole. And a rib for prevention.

(Embodiment) Next, an embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2 show an operating lever 1 according to the present invention,
It is composed of a first lever 2 and a second lever 3, which are connected by a link 4 and are rotatably attached to a base member (not shown) about support shafts 5 and 6, respectively. Support shafts 7 and 8 are formed in the link 4 and are rotatably fitted in the fitting hole of the first lever and the fitting hole of the second lever, respectively. Reference numeral 9 is an elastic piece integrally formed with the link 4 for suppressing rattling between the link 4 and the first lever 2 and the second lever 3.

An operation knob 10 is attached to the tip of the first lever 2 side so as to protrude from an operation panel (not shown). Reference numeral 11 denotes an elastic piece having a claw portion 12 at its tip, which is fitted with a plurality of groove portions (not shown) formed on the base member side to form a click mechanism.

A wire attachment hole 13 is formed in the tip of the second lever 3, and the tip of the inner 15 of the wire 14 is inserted and attached into the wire attachment hole 13 from the top to the back in the drawing. The tip of the outer 16 is fixed to the base member by a clamp 17. In addition, the first lever 2 has a second lever 3
On the inner 15 between the wire mounting hole 13 and the clamp 17 of
As shown in FIG. 4, ribs 18 protruding downward in a generally L-shape
Is provided. The lower wall 19 of the rib 18 is curved upward, and when the operation lever 10 shown in FIG. 15 is wire mounting hole 13
It is provided so as to cover the inner 15 from the side (the surface side in the drawing) to be inserted into the.

In the state shown in FIG. 1 in the wire operation lever having the above-described configuration, the inner 15 of the wire 14 is pulled out from the outer 16 and a substantially middle portion thereof is in a position covered from above by the rib 18.

From this state, when the operation knob 10 is moved downward in the figure and the operation lever 1 is rotated counterclockwise, the inner wire 14 is rotated.
Since 15 is pressed into the outer 16 and is in a compressed state, it tries to buckle upward as shown by the chain double-dashed line in FIG. 3, but it is buckled because it is covered with the rib 18 and the deformation is restrained. It is pushed into the outer 16 without. In addition, since the lower wall 19 of the rib 18 is formed to be curved upward, even if the inner 15 acts to move in the left-right direction in FIG. It does not come off by moving left and right.

As the operating lever 1 rotates counterclockwise, the rib
18 is separated from the inner 15 of the wire 14, but the inner 15 is pushed into the outer 16 and the projecting dimension from the outer 16 is shortened to increase the buckling strength, so even if it is not covered by the rib 18. It will never buckle.

Next, in the state shown in FIG. 2, the inner 15 of the wire 14 is pushed into the outer 16 and the rib 18 is
It is located away from. In this state, when the operation knob 10 is moved to the upper side in the drawing to rotate the operation lever 1 clockwise, the inner 15 of the wire 14 is pulled and there is no problem of buckling.

The buckling prevention rib covering the inner pulled-out state may be provided on the buckling side as in the above embodiment,
If it is provided so as to cover from both sides, buckling can be prevented more reliably. Further, the first lever 2 and the second lever 3 are rotatably attached to the base member, and are linked by a link 4 so that the second lever rotates in conjunction with the rotation of the first lever 2. Therefore, the operating direction of the operating lever 1 is not restricted, and the inner 15 can be pushed in and out of the outer 16 in a direction irrelevant to the operating direction, and the pulling operation can be performed, and the operating stroke of the inner 15 can be sufficiently obtained. It becomes possible. Therefore, the inner 15 can be pushed in and pulled out in various directions by variously selecting the shape and mounting position of the second lever 3.

(Effect of the Invention) As is apparent from the above description, according to the present invention, since the rib for preventing buckling is provided on the operation lever, it is not necessary to provide it on the base member. Therefore, various members on the base member are not necessary. In addition, the wire can be easily arranged even if the two types of levers are provided. Further, the buckling prevention rib is provided so as to cover the inner member in the pulled-out state, and has the effect of effectively preventing buckling when the inner member is pushed in. Further, a first lever rotatably attached to the base member and provided with an operation knob at one end, and a second lever rotatably attached to the base member are attached to the first lever.
Since the second lever is linked by the link so as to rotate in association with the rotation of the lever, the operation direction of the operation lever is not restricted, and the inner is pushed into the outer in a direction irrelevant to this and pulled out. There is an effect that the operation can be performed and a sufficient operation stroke of the inner can be obtained. Therefore, the inner can be pushed in and pulled out in various directions by variously selecting the shape and mounting position of the second lever.
