DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A plug operating mechanism for a rechargeable electric razor according to an embodiment of the present invention will be described with reference to FIGS.

The rechargeable electric razor has a power supply connecting plug 2 which can be taken in and out of the container 1. As shown in FIG. 8, the plug 2 is fixed to a slidable plug support 3. In order to move the plug support (moving body) 3 linearly, the operator (knob) 5 is provided in the recess 4 of the plug support 3.
The lower part 6 of is engaged. The lower portion 6 of the manipulator 5 is formed in a cylindrical shape, and the compression coil spring 7 is arranged inside this. This coil spring 7 has the operator 5 shown in FIG.
And it is always biased upward.

As shown in FIGS. 1 and 2, the upper surface plate (plate-shaped body) 8 made of synthetic resin of the container 1 is provided with a guide groove 9 for guiding the operator 5 and a plurality of notched grooves 10. Has been. The guide groove 9 extends linearly in the direction in which the plug 2 is moved. Three notched grooves 10 are provided at both ends of the guide groove 9, and each of them extends in a direction orthogonal to the guide groove 9. Two projecting pieces 11 are inevitably formed between the cut-out grooves 10. Since the top plate 8 is made of synthetic resin,
The protrusion 11 is elastically deformable in the moving direction of the operator 5.
The tip of the projecting piece 11 projects toward the other edge side from the extension line of one edge of the guide groove 9. At the lower edge of the guide groove 9 in FIG. 1, a step portion 12 that functions as a stopper for the operator 5 is provided.

As shown in FIGS. 4 to 7, the operating element 5 has a cylindrical lower portion 6, a neck portion 13 integrally formed with the lower portion 6, a head portion 14 fixed to the neck portion 13, and a locking convex portion 15. It consists of and. The neck portion 15 inserted into the guide groove 9 is provided with a pair of protrusions 16 protruding in the width direction of the guide groove 9. The locking projection 15 projects upward from the upper surface of the operator lower portion 6 and selectively engages with the locking recess 17 provided on the lower surface of the top plate 8 of the container 1. The planar shape of the tip of the protrusion 11 and the cross-sectional shape of the protrusion 16 are semicircular.

[0011]

[Operation] When the operating element 5 is slid by releasing the lock of the concave portion 17 and the convex portion 15, the head portion 14 of the operating element 5 is pushed down against the upward biasing force of the coil spring 7 with a finger to move in the left-right direction. Slide it. Since the total width of the neck portion 13 and the protrusion 16 is smaller than the width of the guide groove 9, the operator 5 is moved substantially without being restricted by the edge or side wall of the guide groove 9. When the manipulator 5 is moved from right to left in FIG. 1 and the protrusion 16 of the neck 13 of the manipulator 5 reaches the position of the protrusion 11, the tip of the protrusion 11 and the lower edge of the guide groove 9 Since the interval is smaller than the width of the central portion of the guide groove 9, the projection 16 hits the projecting piece 11 and the feeling of operation is increased. When the operator further moves the operating element 5 to the left, the right projection of the two projections 11 elastically tilts to the left in FIG. 1, and the projection 16 chamfered in a planar semicircle shape is the same. It is located in the notch-shaped groove 10 between the two projecting pieces 11 over the tip of the projecting piece 11 that is chamfered in a semicircular shape. Protrusion 1
When the projection 16 gets over 1 the response becomes large and a larger operating force is required than before, so the operator clearly knows that the operator 5 has reached the target position (lock position). Since the diameter of the protrusion 16 is larger than the width of the cut groove 10, the protrusion 16 tilts the left protrusion 11 to the left as shown in FIG. 3 and is held by the two protrusions 11. Even if the operator 5 is operated to move further to the left side, since the upper plate 8 is provided with the step portion 12, the left movement of the neck portion 13 of the operator 5 is limited here, and further Do not move. When the pushing force of the operating element 5 is released after the projection 16 reaches the position shown in FIG. 3, the operating element 5 is moved upward by the force of the coil spring 7, and the concave portion 17 is moved as shown in FIG.
The convex portion 15 is inserted into and the lock is established. This allows
The horizontal movement of the operator 5 and the plug 2 is prevented.

When the plug 2 is pulled into the container 1,
In the state of FIG. 8, the operator 5 is pushed down against the coil spring 7 and slid to the right. As a result, the convex portion 15 comes out of the concave portion 17 to be in the unlocked state, and the projecting piece 11 is pushed by the projecting piece 16 and elastically deforms. 5 moves to the right. When the manipulator 5 is moved to the right end of the guide groove 9, the right protrusion 16 hits the right protrusion 11, and when the operator overcomes this, the response becomes great as in the case of the left protrusion, and it is known that the target position has been reached. You can At the same time, the lock by the concave portion 17 and the convex portion 15 is established.

According to this embodiment, the target position of the manipulator 5 can be accurately known with a very simple structure in which the notch-shaped groove 10 is provided in the upper plate 8. That is, the response to the target position can be obtained without using the uneven engagement using a special spring member. Also, the protrusion 11 is the protrusion 1
Since 6 is held, a locking action occurs. Therefore, a double locking action is obtained.

[0014]

[Modification] The present invention is not limited to the above-mentioned embodiment, and the following modifications are possible.

The number of protrusions 11 can be increased or decreased as required.

In this embodiment, the head portion 14 of the operating element 5 is fixed to the neck portion 13 with an adhesive, but instead of this, the neck portion 13 is fixed to the lower portion 6, or the upper surface plate 8 is passed through the guide groove 9. As described above, it is possible to make a combination of those divided into two.

The present invention is not limited to the movement of the plug 2 and can be applied to a sliding mechanism such as a variable resistance slider in electric equipment.

By increasing the holding force of the protrusion 16 by the protrusion 11, the locking mechanism by the recess 17 and the protrusion 15 can be omitted.

In order to increase the elasticity of the projecting piece 11, the projecting piece 11
The width of the root part of can be narrower than other parts. Also, of the two protrusions 11 in FIG. 3, the one on the right side that first contacts the protrusion 16 is desirably elastically deformed symmetrically in both left and right directions, but the protrusion on the left side that contacts second is the protrusion 1
Since it is irrelevant to the overriding of 6, the protrusion 16 may be formed to extend at an angle other than a right angle with respect to the guide groove 9 in a state before hitting.

[0020]

As is apparent from the above, according to the present invention, it can be known with a simple configuration that the operator has slid to the target position.
