Abstract

A device (12) for driving in nails has a nail magazine (14), in which nails (1) each having a longitudinal cylinder body as nail head can be put on magazine, the nails being forced towards a driving-in channel (16). The nail (1) which is in the driving-in channel (16) can be driven into a wall by means of a ram (17) having a pusher (18). An indexing device (19, 20, 21) indexes audibly the ram (17) in the device (12) for driving in nails as soon as the nail (1) is completely driven into the wall.

Claims

1. A device for driving nails into a wall, each of the nails having an elongated cylindrical nail head, the nail head having an abutment surface to which a shaft is connected so as to limit insertion of the nail into the wall and a recess for engaging a loop, said device comprising:

a nail magazine for storing a plurality of the nails;

a driving-in channel for receiving one of said plurality of the nails from the magazine;

means for forcing said plurality of the nails toward said driving-in channel;

a ram located in said driving-in channel and movable axially relative to the nail received in said driving-in channel so as to drive the nail into the wall; and

indexing means for audibly indexing the ram when the ram is depressed to a point where the nail is completely driven into the wall.

2. The device as claimed in claim 1, further comprising a housing for receiving said nail magazine and said driving-in channel, wherein said indexing means comprises an indexing recess located in said ram, a ball located in said housing, and a spring for biasing the ball toward said indexing recess when the ram is depressed to said point.

3. The device as claimed in claim 1, further comprising a housing for receiving said nail magazine and said driving-in channel, said housing having a planar abutment surface which is placed against the wall, a planar upper surface, a housing section having an upper wall which extends in a semicircle above said upper surface, said driving-in channel being located in said housing section, wherein the nail received in the driving-in channel has a longitudinal axis located at the intersection of the upper surface and a vertical line running radially through the upper wall of the housing section.

4. The device as claimed in claim 3, further comprising a mark extending along a top portion of said upper wall parallel to a longitudinal axis of the ram.

5. A device for driving nails into a wall, comprising:

a nail magazine;

a plurality of nails located in said magazine, each of the nails having an elongated cylindrical nail head, the nail head having an abutment surface to which a shaft is connected so as to limit insertion of the nail into the wall and a recess for engaging a loop;

a driving-in channel for receiving one of said plurality of nails from the magazine;

means for forcing said plurality of nails toward said driving-in channel;

a ram located in said driving-in channel and movable axially relative to the nail received in said driving-in channel so as to drive the nail into the wall; and

indexing means for audibly indexing the ram when the ram is depressed to a point where the nail is completely driven into the wall.

6. The device as claimed in claim 5, further comprising a housing for receiving said nail magazine and said driving-in channel, wherein said indexing means comprises an indexing recess located in said ram, a ball located in said housing, and a spring for biasing the ball toward said indexing recess when the ram is depressed to said point.

7. The device as claimed in claim 5, further comprising a housing for receiving said nail magazine and said driving-in channel, said housing having a planar abutment surface which is placed against the wall, a planar upper surface, a housing section having an upper wall which extends in a semicircle above said upper surface, said driving-in channel being located in said housing section, wherein the nail received in the driving-in channel has a longitudinal axis located at the intersection of the upper surface and a vertical line running radially through the upper wall of the housing section.

8. The device as claimed in claim 7, further comprising a mark extending along a top portion of said upper wall parallel to a longitudinal axis of the ram.
