Abstract

The invention relates to a device for driving a securing element into a substrate, having a mechanical energy store for storing mechanical energy; an energy transmitting element for transmitting energy from the mechanical energy store to the securing element; an energy transmitting device for transmitting energy from an energy source to the mechanical energy store; a housing with a first and a second housing part, said first housing part being connected to the second housing part in order to form an interior between the first and second housing part, the mechanical energy store being arranged in said interior; and an intermediate element, by means of which the mechanical energy store can be secured to the first housing part at least temporarily while energy is stored in the mechanical energy store.

First claim

The invention claimed is:

1. A device for driving a fastening element into an underlying surface, comprising a mechanical energy accumulator for storing mechanical energy; an energy transmitting element for transmitting energy from the mechanical energy accumulator to the fastening element; an energy transmitting device for transmitting energy from an energy source to the mechanical energy accumulator; a housing with a first housing part and a second housing part, wherein the first housing part is connected to the second housing part to form an interior, and the mechanical energy accumulator is arranged in the interior between the first and second housing part; and an intermediate element, wherein, during assembly of the device, while the mechanical energy accumulator is pretensioned with energy, the intermediate element secures, at least temporarily, the mechanical energy accumulator to the first housing part.

2. The device according to claim 1 , wherein the mechanical energy accumulator is supported firstly on the first housing part, and secondly on the intermediate element, against release of the energy stored in the mechanical energy accumulator.

3. The device according to claim 2 , wherein the intermediate element divides the interior into a first partial chamber and a second partial chamber.

4. The device according to claim 1 , wherein the mechanical energy accumulator is supported only on the first housing part against release of the energy stored in the mechanical energy accumulator.

5. The device according to claim 1 , wherein the mechanical energy accumulator is supported only on the intermediate element against release of the energy stored in the mechanical energy accumulator.

6. The device according to claim 1 , wherein the intermediate element divides the interior into a first partial chamber and a second partial chamber.

7. The device according to claim 6 , wherein the intermediate element separates the first and second partial chambers from one another in a dustproof manner.

8. The device according to claim 7 , wherein the intermediate element comprises a sealing element for separation of the first partial chamber from the second partial chamber in an at least partial dustproof manner.

9. The device according to claim 7 , wherein the intermediate element separates the first and second partial chambers in an air-tight manner from one another.

10. The device according to claim 7 , wherein the first partial chamber is closed off from surroundings of the device in a dustproof manner, and the second partial chamber is ventilated with ambient air.

11. The device according to claim 7 , wherein the mechanical energy accumulator is arranged in the first partial chamber.

12. The device according to claim 6 , wherein the first partial chamber is closed off from surroundings of the device in a dustproof manner, and the second partial chamber is ventilated with ambient air.

13. The device according to claim 12 , wherein the first partial chamber is closed off from the surroundings of the device in an air-tight manner.

14. The device according to claim 6 , wherein the mechanical energy accumulator is arranged in the first partial chamber.

15. The device according to claim 6 , wherein the energy transmission device comprises a motor that can be mounted on the intermediate element and/or arranged in the second partial chamber.

16. The device according to claim 6 , wherein the energy transmission element comprises a transmission that is mounted on the intermediate element and/or arranged in the first partial chamber.

17. The device according to claim 6 , wherein the energy transmission device comprises a motion converter having a rotational drive and a linear output, arranged in the first partial chamber, that converts a rotational movement into a linear movement.

18. The device according to claim 17 , wherein the motion converter comprises a spindle drive with a spindle and a spindle nut arranged on the spindle.
