Abstract

Screwdriver handle has a storage chamber for screwdriver bits, the storage chamber being displaceable from a closed position into an open position by axial displacement of two parts of the handle with respect to one another. One handle part has a core, which is disposed in a cavity in the other handle part. The two handle parts are held in the closed position of the storage chamber by latching means movable out of a latching position by pressure on an actuating zone ( 8 ) associated with an end side of the handle.

Claims (15)

1. Handle of a screwdriver, the handle comprising a first handle part, a second handle part, and a storage chamber for screwdriver bits or the like, the storage chamber being displaceable within the handle from a closed position into an open position by axial displacement of the two handle parts with respect to one another, the first handle part having a core, which is disposed in a cavity in the second handle part, and the two handle parts being held in the closed position of the storage chamber by latching means, wherein the latching means is movable out of its latching position by pressure on an actuating push button located on an end of the second handle part wherein the push button is configured so as to be axially displaceable when under pressure in a direction toward the first handle part, wherein the push-button is fitted in a cutout in the end side of the handle, wherein the latching means is a pivotable spring tongue which has a latching projection at its free end and interacts with a latching step, and wherein an actuating cam is formed by the push-button and acts on the spring tongue in order to cancel the latching position.

2. Handle according to claim 1 , wherein the push-button is displaceable into a pot-shaped cutout counter to the force of a restoring spring.

3. Handle according to claim 1 , wherein in the event of pressure on the push-button, the latching means is moved out of the latching position when the end face of the push-button is displaced past an opening edge of a cutout.

4. Handle according to claim 1 , wherein the spring tongue is formed integrally with the material of the core.

5. Handle according to claim 1 , wherein the spring tongue is formed by an end portion of the core.

6. Handle according to claim 1 , wherein said latching means is one of a plurality of latching means located diametrically opposite one another.

7. Handle according to claim 1 , wherein the actuating cam acts in the axial direction on a control slope of the spring tongue, which likewise extends in the axial direction.

8. Handle according to claim 1 , wherein the two handle parts are displaced from the closed position into the open position by the force of a prestressed spring following pressure on the actuating zone.

9. Handle of a screwdriver, the handle comprising a first handle part, a second handle part, and a storage chamber for screwdriver bits or the like, the storage chamber being openable by axial displacement of the two handle parts with respect to one another, the first handle part having a core which is disposed in a cavity in the second handle part and has at least one latching means, which latching means, in a closed position of the storage chamber, interacts with a mating catch of the second handle part that includes the cavity, wherein the latching means leaves its latching position of its own accord as a result of pressure on an actuating zone of the first handle part which includes the mating catch, wherein the actuating zone is associated with the second handle part which includes the cavity, and the latching means is a pivotable spring tongue which has a latching projection at its free end and is formed integrally with the material of the core.

10. Handle according to claim 9 , wherein the mating catch is a latching step.

11. Handle of a screwdriver, the handle comprising a first handle part, a second handle part, and a storage chamber for screwdriver bits or the like, the storage chamber being openable by axial displacement of the two handle parts with respect to one another, the first handle part having a core which is disposed in a cavity in the second handle part and has at least one latching means, which latching means, in a closed position of the storage chamber, interacts with a mating catch of the second handle part that includes the cavity, wherein the latching means leaves its latching position of its own accord as a result of pressure on an actuating zone of the first handle part which includes the mating catch, wherein the latching means is one of two latching means located diametrically opposite one another.

12. Handle of a screwdriver, the handle comprising a first handle part, a second handle part, a spring, and a storage chamber for screwdriver bits or the like, the storage chamber being openable by axial displacement of the two handle parts with respect to one another, the first handle part having a core, which is disposed in a cavity in the second handle part and has at least one latching means, which latching means, in a closed position of the storage chamber, interacts with a mating catch of the second handle part that includes the cavity, wherein the two handle parts are spring-loaded with respect to one another in such a manner that, after a latching has been cancelled, the two handle parts are moved apart by the spring, until they reach an open position, and wherein a push-button is provided for the cancellation of the latching when the button is pressed along a direction that is coaxial with the handle.

13. Handle according to claim 12 , wherein the spring is a compression spring, and is stressed in a closed position of the handle parts.

14. Handle according to claim 12 , wherein the open position is a partially open position.

15. Handle of a screwdriver, the handle comprising a first handle part, a second handle part, and a storage chamber for screwdriver bits or the like, the storage chamber being displaceable within the handle from a closed position into an open position by axial displacement of the two handle parts with respect to one another, the first handle part having a core, which is disposed in a cavity in the second handle part, and the two handle parts being held in the closed position of the storage chamber by a latch mechanism that comprises a cantileverable spring tongue which has a latching projection at its free end and which interacts with a latching step, wherein the latch mechanism is movable out of its latching position by pressure on an actuating push button located on an end of the second handle part wherein the push button is configured so as to be displaced under pressure in the direction of the first handle part, and wherein an actuating cam is formed by the push-button and acts on the spring tongue in order to cancel the latching position.
