Description

[Detailed Description of the Invention] (Industrial field of application) The present invention stores a rod body such as a lip collar, a crayon, a pass, and an eraser in a case, and slides a knob freely to put it in and out from the case at any position. The present invention relates to a stick-out device that can be locked.

(Prior Art) Conventionally, as shown in FIGS. 5 to 8, a round bar-shaped eraser 30 is fitted and inserted into a cylindrical case 31, one end of which is fixed to a slider 32, and a button 33 integrated with the slider 32 is cased. 31 A plurality of locking holes 35 projecting upward from the slit 34 formed in the axial direction and provided at regular intervals in the axial direction of the case 31 facing the slit 34, and the locking projection 36 on the lower surface of the slider 32 is elastically actuated by the spring 37. It is adapted to fit in the locking hole 35.

When the eraser 30 is pushed out, if the button 33 is pushed forward, the button 33 is pushed down and inclined forward as shown in FIG. 7, and the locking projection 36 comes out from the locking hole 35, so that the eraser 30 can be pushed out. When storing the eraser 30, push the button 33 downward to retract the eraser 30.

(Problems to be solved by the invention) By the way, in the above-mentioned conventional technique, when the eraser is fed out, the button is pushed forward, and when the eraser is stowed, the button is pushed back so that the operation is troublesome and requires skill. There was a problem that it was not common.

(Means for Solving Problems) In order to solve the above problems, the present invention forms a slit in the longitudinal direction of a case, forms sawtooth notches on both sides thereof, and slides in the case. The rear end of the rod is connected to one end of the slider, and the bottom of the locking spring whose both sides are extended upward is placed on the upper surface of the slider so that they can move integrally. A pressing member having a V-shaped pressing portion on the lower surface that can be passed through the slit is formed by bending it vertically to form a locking portion, which is fitted into the sawtooth notch portion by its own elasticity to prevent movement. It is arranged between the locking parts, and the locking part of the locking spring is pushed downward by the movement of the pressing member in the longitudinal direction of the case so that the fitting into the notch part can be released. is there.

Hereinafter, a specific description will be given based on the illustrated embodiment.
Reference numeral 1 is a case made of an elongated flat box body. A slit 2 is formed in the center of the narrow upper surface 1a in the longitudinal direction, and sawtooth notches 2a are formed on both sides of the slit 2 so as to face each other. 3 is case 1
The rear end of the flat eraser 4 is connected by a slider that slides inside. Numeral 5 is a V-shaped locking spring, the bottom 5a of which is fitted and placed in the recess 3a of the upper surface of the slider 3 and both ends of which are bent vertically downward and horizontally bent outward.
Is elastically fitted into the serrated notch 2a without play and is prevented from sliding back and forth. Reference numeral 6 is a V-shaped pressing portion inserted into the V-shaped spring 5, which is the narrow upper surface 1a of the case 1.
The upper button 7 and the connecting piece 8 that can pass through the slit 2 are integrally connected.

Next, the operation will be described. Figure 4 shows the still state,
The V-shaped spring 5 both side engaging portions 5b are fitted in the notch portion 2a without backlash. Even if the button 7 is lightly pushed back and forth, there is no forward or backward movement.

When the button 7 is moved as shown in FIG. 4, the locking portion 5b in the moving direction is pushed down by the connecting piece 8 passing through the slit 2, and at the same time, the rear locking portion 5b is also gently pushed below the notch 2a. Then, it is dragged under the protrusion 2b and advances in the traveling direction.

Further, as shown in FIG. 4, when the front locking projection 5b passes under the projection 2b, it fits into the notch 2a from below the projection 2b without any rattling, and at the same time the rear locking portion 5b also projects. It projects from the bottom of 2b and fits into the notch 2a without play, resulting in the stationary state shown in FIG. While the button 7 is being pushed forward, the above operation is repeated and a clicking sound is generated. The same operation is performed when the button 7 is retracted.

In addition to the eraser, the rod can be applied to various rod-shaped bodies such as lip collars, crayons, and passes.

(Effect) According to the present invention, a slit is formed in the longitudinal direction of the case, sawtooth notches are formed on both sides of the slit, and one end of the slider that slides in the case is connected to the rear end of the rod body. The bottom of the extended locking spring is placed on the upper surface of the slider so that it can move integrally, and both ends of the locking spring are bent downward substantially vertically to form the locking portion, and the elasticity of the locking spring causes A pressing member having a V-shaped pressing portion on the lower surface which is inserted into the sawtooth notch so as to prevent movement and which can pass through the slit is arranged between the locking portions, and the case length of the pressing member is long. The locking part of the locking spring is pushed downward by the movement in the direction so that the fitting into the notch can be released, so that the locking part can be inserted into the notch and the notch by simply pressing the button back and forth. Sly out and out It is convenient for anyone to operate it easily.
