Abstract

Device for lifting a nail, essentially consisting of a contour pointing towards the nail head for gripping under the nail head, characterized in that the contour (19) pointing towards the nail head (20) has a concave, arched course.

Description

The invention relates to a device for lifting a nail, consisting essentially of a nail head facing contour for grasping the nail head.

Such a device is for example from the GB 754,647 in which a nail puller with a curved tip is disclosed, in which a V-shaped nail claw is incorporated.

Furthermore, from the DE-GM 200 09 244 U1 also a nail iron with a curved tool surface known in which a V-shaped nail claw is arranged. For both above-described devices according to the prior art, the disadvantage is that hereby nails, in particular roofing nails, are very difficult to reach, unless the nail heads have a certain distance to the base, in which the nails were taken.

The object of the invention is therefore to optimize a device for lifting a nail in such a way that as little as possible of the pad spaced nail heads and nail heads made of softer material can be reliably taken.

The solution of the problem arises from the features of claim 1, in particular the features of the characterizing part, according to which the contour facing the nail head has a concave, arcuate course.

The device according to the invention has the advantage that, due to its concave, arcuate course, it can engage not only in point (tangential) a nail stuck in the base in the area of its nail head, but also along a larger contact area between the arcuate contour and the also round nail head that the chance of taking under a relatively close to the pad adjacent nail head is significantly increased. In addition, the force of the nail lifter on the nail head is not selectively, but distributed over a larger contact area. This reduces the risk of deformation of the nail head.

In an advantageous embodiment, the contour is formed like a blade. Due to the blade-like design, the chance of under-gripping the nail head is significantly improved because it allows the partial penetration of the cutting-like contour in a wooden base.

Alternatively, it is also possible that the contour is formed circular-segment-shaped and oval.

Furthermore, the invention relates to a hammer, in particular Dachdeckerhammer, consisting essentially of a shaft with a handle disposed thereon and arranged on the shaft hammer track and hammer tip.

From the documentary unverifiable prior art, it is basically known in hammers and roofing hammer, for example, incorporate a keyhole-like opening in the stem area, which serves as a nail puller. In the area of the larger diameter of the keyhole-like opening, a nail protruding from a base by a certain amount can then enter the opening. By slightly moving the hammer sideways, it gets into the area of smaller diameter, which acts like an undercut. By pivoting the bearing on the base hammer head then a force can be deployed on the nail, which leads to the extraction of the nail from the pad.

However, the disadvantage of such hammer-integrated nail puller is that the application area is limited to nails whose nail head is to some extent removed from the pad, so that they can be attacked.

The object of the invention is, therefore, to optimize a hammer in such a way that, as far as possible, nail heads that are even slightly spaced from the base and also nail heads made of softer material can be removed.

The solution of the problem arises from the features of claim 5, in particular the features of the characterizing part, according to which between the hammer track and hammer tip about the shaft opposite a device for lifting a nail mounted in a wooden base is arranged, the contour of which for engaging the nail head a concave , arcuate course has.

The solution according to the invention has the advantages set out above.

In addition, there is the fact that it is advantageous to integrate in a hammer, in particular Dachdeckerhammer, in addition to a conventional nail puller and the nail lifter according to the invention, so that a larger area of use is created with a tool.

Further advantages of the invention will become apparent from the following claims and the description of an embodiment. Show it:

1 a side view of a roofer hammer,

2 a partial sectional view of a roofer hammer according to section line II / II in 1

3 enlarged detail of the nail lifter of a rooftop hammer in use.

In the drawings, a roofing hammer is a whole with the reference numeral 10 designated. The roofer hammer 10 consists of a shaft 11 with handle arranged thereon 12 and one at the opposite end region cohesively on the shaft 11 arranged hammer track 13 and hammer tip 14 , Between Hammerbahn 13 and hammer tip 14 is in the transition area to the shaft 11 a conventional nail puller 15 with a keyhole-like opening 16 arranged, which is surrounded by a wedge-shaped boundary B circumferentially.

In addition, the roofer hammer points 10 in the transition area between Hammerbahn 13 and hammer tip 14 on an outer contour 17 a nail lifter 18 on. With the nail lifter 18 it is a circle-shaped, concave contour 19 , which is formed like a blade. The cutting-like formation of the nail lifter 18 one recognizes in particular in the 2 in the area of the circular section-shaped, concave contour 19 ,

In the 3 it can be seen that the circle-shaped nail lifter 18 whose contour matches the circular contour of a nail head 20 adapted, a very large contact area with the nail head 20 has, so that the chance to reach under the nail head 20 significantly enlarged. In addition, it is with the nail lifter according to the invention 18 with a wooden pad 21 is possible, if necessary, this in the nail head 20 partially remove, so that in this way a gripping the nail head 20 and lifting it becomes possible.

In particular, with nails of softer material is added that the introduction of force is advantageously not selective, but distributed over a larger contact area, so that the risk of deformation of the nail head 20 , without this from the wooden base 21 moved out, is significantly lower.
