Abstract

PROBLEM TO BE SOLVED: To eliminate troublesomeness of stopping pushing of a feeding wheel during character erasing by providing the wheel for supporting at a wall of a sheath via an operating member, and providing an elastically returning force for releasing a pawl tip from a side face only during a period of the state that the tip is locked to or released from a side of an eraser and bringing it into pressure contact with the eraser. SOLUTION: A rod-like eraser 2 is inserted into a sheath 1. A space 10 is formed by a partition wall 9 between a side of the sheath 1 and a side of the eraser 2. An operating member made of an oscillating arm part 4, a locking pawl part 5 and a spring part 6 provided at an end side is constituted. The member is oscillatorily mounted in the space 10. A feeding wheel 3 is rotatably supported to the part 4. The oscillating range of the member is regulated, and its part is removed from the sheath. When this part is pressed against an operating action of the part 6 by hand or fingers, the wheel 3 is brought into pressure contact with the eraser. The part 5 is released from the eraser 2. At the time of releasing the part 5 from the eraser 2, the wheel 2 is released from the eraser 2, the part 5 is pierced to prevent retreating of the eraser 2.

The type described in the above-mentioned prior art has a trouble that it is necessary to hold down the feeding vehicle during the erase operation. An object of the present invention is to provide a new extension type rubber eraser holder in which the above-mentioned inconvenience is eliminated and other ingenuities are applied.

[0004]

In order to achieve the above-mentioned object, a feed-out type eraser holder according to the present invention is loaded with a rod-shaped eraser 2 in a sheath 1 in a state in which the rod-like eraser 2 can be arbitrarily drawn out and retracted by a feed-out vehicle 3. And a feeder wheel 3 having an outer peripheral surface pressed and detached from the side surface of the rod-shaped eraser 2 on the wall of the sheath 1 via an operating member 13, and a toe having a side surface of the eraser 2. The locking claw portion 5 provided on the operating member 13 in a state in which the toe is separated from the side surface of the eraser 2 only while the outer peripheral surface of the feeding vehicle 3 is pressed against the rod-shaped eraser 2. And an elastic portion that applies a force to the feeding vehicle 3 to return to the detached state and a force to the locking claw portion 5 to return to a locked state. The arm 4, the locking claw 5, and the spring portion 6 are integrally formed of a hard plastic having a slight elasticity.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In a first embodiment shown in FIGS. 1 to 5, a sheath 1 is made of a hard plastic, in which the sheath 1 can advance and retreat toward an outlet 8 of the sheath 1 and an outlet. 8, the rod-shaped eraser 2 is inserted so that the tip can be exposed, and a space 10 is formed between the side surface of the sheath 1 and the side surface of the eraser 2 by a partition wall 9.
A rocking arm 4 having support shafts 11 and 12 on both sides of the base end and a locking claw 5 provided on the base end side, respectively, using hard plastics having a slight elasticity. An actuating member 13 comprising a spring portion 6 provided on the distal end side is constituted.
2 is rotatably fitted to shaft holes 14 and 15 provided in advance on the wall of the sheath body 1 and is mounted so as to be swingable.
The feeding vehicle 3 is rotatably supported on the swing arm 4 at the center shaft 16 around the center shaft 16.
8 is fitted in slots 19 and 20 provided in advance on the wall of the sheath body 1 to regulate the swing range of the operating member 13 and a hole in which a part of the feeding vehicle 3 is previously opened in the wall of the sheath body. When the part 22 is pushed out by hand against the force of the spring part 6 and pushed out, the feeding vehicle 3 comes into pressure contact with the rod-shaped eraser 2 and the locking claw part 5 is pushed into the rod-shaped eraser. Away from 2,
When the finger is released, the feeding vehicle 3 is disengaged from the rod-shaped eraser 2 by the action force of the spring part 6 and the locking claw 5 is pierced by the rod-shaped eraser 2 so that the rubber eraser 2 is retracted. It is intended to prevent it.

In the second embodiment shown in FIGS. 6 to 10, a sheath 1 is made of a hard plastic, in which the sheath 1 can advance and retreat toward an outlet 8 of the sheath 1 and an outlet 8. The rod-shaped eraser 2 is inserted so that the tip can be exposed from the same, and a recess 27 is formed between the side surface of the sheath 1 and the side surface of the eraser 2,
An actuating member 13 having a locking claw 5 is inserted into a base end formed of a metal plate in the recess 27, and a portion near the base end of the actuation member 13 is swingably supported by the support shaft 11, The delivery vehicle 3 is rotatably supported on the center of the operating member 13 at a position close to the front end thereof, and a part of the delivery vehicle 3 is taken out of a hole 21 provided in a wall of the sheath body. 27, a leaf spring 28 is inserted therein, and its base end is fixed to the wall surface of the recess 27. The elastic end 29 of the leaf spring 28 is
When the portion 22 that has come out of the delivery vehicle 3 is pushed by a finger against the force of the leaf spring 28 to engage with the tip of the delivery spring 3, the pushing force is applied to the tip of the delivery vehicle 3. The inside of the car 3 comes into pressure contact with the rod-shaped eraser 2 and the locking claw 5 separates from the eraser 2, and when the finger is released, the feeding car 3 is separated from the eraser 2 by the action force of the leaf spring 28 and locked. In this state, the claw portion 5 sticks into the side surface of the eraser 2 to prevent the eraser 2 from retreating.

In the third embodiment shown in FIGS. 11 to 18, a sheath 1 is made of a hard plastic, in which the sheath 1 can be advanced and retracted toward an outlet 8 of the sheath 1 and an outlet 8 is provided. The rod-shaped eraser 2 is inserted so that the distal end can be exposed from the front end, and a recess 27 is formed between the side surface of the sheath body 1 and the side surface of the eraser 2. The operation member 13 having the claw portion 5 is inserted and the operation member 13
Is pivotally supported by the support shaft 11, and a leaf spring 28 is inserted into the recess 27 and its proximal end is fixed to the wall surface of the recess 27. The elastic end 29 is engaged with the distal end of the operating member 13 to apply a push-up force to the distal end, and the auxiliary member 30 of the operating member 13 made of a spring plate is disposed outside the side surface of the sheath body 1. The base end of the auxiliary member 30 is fixed to the wall of the sheath 1, and the delivery vehicle 3 is freely rotatably supported at the free end of the auxiliary member 30 with support walls 31, 32 and a center shaft 33. The inside of the car 3 enters the casing 1 through the through-hole 34 provided in the side wall of the casing 1, and the outside thereof is also formed in the square hole 35 provided in the auxiliary member 30.
And an inclined surface 36 is provided at the tip end of the operating member 13, and one outer end surface of the center shaft 33 of the feeding vehicle 3 is slidably pressed against the inclined surface 36, and the feeding is performed. The inside of the feeding vehicle 3 is pressed against the rod-shaped eraser 2 when the finger is pushed into the part 22 that has come out of the vehicle 3 and the locking claw 5 has the inclined surface 36 and the outer end surface of the center shaft. When the finger is released, the feeding vehicle 3 is separated from the eraser 2 and the locking claw 5 pierces the side surface of the eraser 2 when the finger is released. In such a state, the retraction of the eraser 2 is prevented.

[0008]

The eraser 2 can be set in the extended state or the immersion state by turning the delivery vehicle 3 while pressing it, and the leading end of the eraser 2 is extended to a proper length before the delivery vehicle. By releasing the lock 3, the locking claw 5 is locked to the eraser 2, and the character erase operation can be performed in this released state.

[0009]

The extension type rubber erasure holder according to the present invention comprises:
As described above, there is the convenience that the erase operation can be performed with the fingers released from the feeding vehicle 3, and the detached state of the feeding vehicle 3 and the blocking function state of the locking claw 5 are ensured. Is provided, there is an advantage that the assembling and configuration can be made extremely simple and easy.
