Description

The present invention relates to a knob used for a slide operation member such as a slide switch or a slide volume of various devices.

In test equipment such as a thermostatic chamber, temperature control, which is a precondition for testing, is an important factor that affects the test results. Since it is merely protruding outward, the knob will not be removed from the original setting position due to impacts when opening and closing the door of the equipment storage case, external vibration from the surrounding environment, and inadvertent contact with clothes and equipment. It may be changed intentionally, and the test results may not be obtained due to changes in test assumptions, which may necessitate re-experiment.

As a slide operation mechanism and a slide knob applied to an electronic device, a device that gives a good click feeling to the operator to clearly recognize the switching of the slide switch has been developed (see Patent Document 1). ), And a technique for stably stopping and holding the sliding operation member at the original set position has not yet been proposed.

Japanese Patent Laid-Open No. 11-25803

An object of the present invention is to provide a slide-type operating member knob that can be stably stopped and held at an initial set position by a simple structure.

The object of the present invention is a knob used for a slide-type operation member such as a slide-type switch or a slide-type volume of a device, and is fixed to the tip of the slide member protruding from a guide groove of a storage case of the device A fixed shaft, a knob main body fitted to the outside of the fixed shaft and movable along the length direction of the sliding operation member, a rubber plate mounted on the back surface of the knob main body, and the fixed shaft Friction contact resistance of the rubber plate, which is accommodated in a cylindrical space between the knob bodies and includes a compression coil spring that moves and urges the knob body toward the outer surface of the storage case, and is pressed against the outer surface of the storage case Thus, the knob main body is stopped and held at the initial set position.

The slide-type operation member knob of the present invention has a fixed shaft fixed to the tip of the slide-type operation member protruding from the guide groove of the device storage case, and is movable along the length direction of the slide-type operation member. The main body is fitted to the fixed shaft, and the knob main body is moved and urged toward the outer surface of the storage case by a compression coil spring accommodated in a cylindrical space between the fixed shaft and the knob main body. After moving the sliding operation member to a desired position according to the scale attached along the guide groove, when the finger is released from the knob main body, the knob main body is moved to the outer surface of the storage case by the bias of the compression coil spring. The rubber plate attached to the back surface of the knob body is pressed against the outer surface of the storage case.

The movement of the knob body is accurately restrained by a sufficiently large frictional contact resistance acting between the rubber plate pressed against the outer surface of the storage case and the storage case. For this reason, the position of the sliding operation member is unintentionally changed from the initial set position due to an impact at the time of opening and closing the door of the storage case, external vibration from the surrounding environment, and inadvertent contact of clothes and equipment. There is nothing.

In the illustrated embodiment, the tip of the strip-type sliding operation member 2 connected to the sliding adjustment mechanism (not shown) of the device 1 protrudes from the guide groove 4 of the device storage case 3. The tip is provided with a rectangular parallelepiped knob body 5. An operation direction indicating character 6 “PULL” is engraved on the lower front surface of the knob body 5, and a circular cavity 7 is formed deeply in the front-rear direction on the upper front surface of the knob body 5, leaving the inner bottom wall 8. ing. A square hole 9 into which the sliding operation member 2 is inserted is formed in the center portion of the inner bottom wall 8 so as to penetrate in the front-rear direction.

A rectangular recess 10 is formed on the back surface of the inner bottom wall 8, and the rectangular rubber plate 11 accommodated in the recess 10 is firmly bonded to the back surface of the inner bottom wall 8. A passage hole 12 for the sliding operation member 2 is formed at the center of the rubber plate 11. A male screw portion 13 is formed at the most distal end portion of the sliding operation member 2. The cylindrical fixed shaft 14 is inserted into the hollow portion 7 of the knob body 5 with a margin, and the male screw portion 13 of the sliding operation member 12 is screwed and fixed to the female screw portion 15 at the center.

A compression coil spring 16 is accommodated in the cavity 7 left between the inner peripheral surface of the knob body 5 and the outer peripheral surface of the fixed shaft 14, and the front end of the compression coil spring 16 is the front end of the fixed shaft 14. The rear end of the compression coil spring 16 is in contact with the front surface of the inner bottom wall 8 of the knob body 5. A disc-like cap 18 is fitted and fixed to the front end of the cavity 7 of the knob body 5.

When the sliding operation member 2 is moved to another setting position, the knob main body 5 is pulled forward and the rubber plate 11 is pulled away from the outer surface of the storage case 3. At this time, the compression coil spring 16 is further compressed and loaded between the front end flange 17 of the fixed shaft 14 and the inner bottom wall 8 of the knob body 5. When the knob main body 5 is pulled sideways according to a scale (not shown) attached along the guide groove 4 and the sliding operation member 2 is moved to a desired setting position, when the finger is released from the knob main body 5, The knob body 5 is moved toward the outer surface of the storage case 3 by the restoring force of the compression coil spring 16, and the rubber plate 11 is pressed against the outer surface of the storage case 3.

Since the knob body 5 is stopped and held at the new scale position by the frictional contact resistance acting between the rubber plate 11 and the storage case 3, the sliding operation member 2 is also accurately stopped and held at the new set position.

It is a front view of the knob for slide operation members concerning one example of the present invention. It is a right view of the knob of FIG. It is a rear view of the knob of FIG. It is a top view of the knob of FIG. It is the sectional view on the AA line of FIG. It is the BB sectional view taken on the line of FIG.
