专利说明:

The invention relates to a chisel double impact hammer according to claim 1 and a use of the chisel double impact hammer according to claim 10.
The hitherto known form and design of a hammer consists of a single piece of iron, which is connected by a hole with a stem. The disadvantage of the hitherto known hammer is that when the hammer hits the workpiece, it immediately drifts off, which automatically leads to a reduction in the impact force and the impact efficiency on the workpiece.
It is an object of the present invention to provide a hammer with increased impact and impact efficiency.
This object is achieved by a chisel double impact hammer according to claim 1. According to the invention, the chisel double impact hammer comprises a hammer base and a hammer shell, which is hinged in the direction of impact of the back of the hammer base on this movable, further comprising a guided in the hammer base chisel assembly with at least one chisel, the chisel assembly is connected to the hammer shell such that the chisels of a movement of the hammer shell in relation to the hammer base following in the direction of impact protrude from a hammer tip of Hammeruntererteils or retracted into the hammer tip.
The chisel double hammer has very special, hitherto unknown positive properties. The construction of the chisel double impact hammer according to the invention has the result that the hammer not only makes a normal hammer blow, but hits the chisel in the next lower spot when hitting a free space on the workpiece (for example stone). This is thus caused by the double blow of the hammer shell on the hammer base. Due to the short path of the upper part of the hammer to the lower part of the hammer, a maximum of one hundredth of a second passes until the chisel hits the workpiece.
The special feature of this invention is that the chisel double impact hammer hits when hit not only on a wider area (fixed and moving part), but it is also prevented by the extended chisel drifting, which is the whole clout can act precisely. The efficiency of the chisel double impact hammer is thereby significantly increased compared to a conventional hammer. Another advantage for the manufacturer is the simplicity of the chisel double hammer. The few individual parts are relatively easy to produce and are individually interchangeable when worn.
Preferably, the hammer shell is hinged along a guide movable on the hammer base. As a result, during acceleration of the chisel double impact hammer in the direction of impact, the hammer upper part (as viewed in the direction of impact) of the back of the hammer base is moved or separated from the hammer base as a result of the inertia of the mass. Upon impact of the hammer tip of the hammer base of the chisel double hammer on a solid object, e.g. a workpiece, or on a solid surface, e.g. a wall, the hammer shell is accelerated as a result of inertia on the guide towards the rear surface of the hammer base.
Preferably, the guide comprises at least one attached to the back of the hammer base retaining bolts, on which the hammer shell is fitted over a hole provided herein, wherein the retaining bolt and the bore are aligned in the direction of impact. The retaining bolts hold the respective two parts together, respectively spaced from each other. This embodiment forms a particularly simple and reliable guide. For example, and preferably at least two, preferably four separate retaining bolts are attached to the back of the hammer base. The number of spent retaining bolts corresponds to a number of corresponding holes that are present in the hammer shell and the hammer base and match in size and in position. The retaining bolts are guided through these holes.
Preferably, the chisel double hammer further comprises a stop attached to the distal end of the retaining bolt for limiting movement of the hammer shell in relation to the hammer base. The maximum distance between the hammer base and the hammer top of the chisel double impact hammer is thus limited by the stop. This maximum distance can be adjusted by appropriate choice of the arrangement of the stop on the respective retaining bolts such that the gap between the hammer shell to hammer base is about 5-10 mm.
Preferably, the chisel double hammer further includes at least one biasing element which applies a biasing force between the hammer base and the hammer shell. By biasing element hammer base and hammer shell are reliably biased spaced apart biased. This can prevent rattling between the hammer base and the hammer shell of the chisel double hammer. Also, thus a risk of injury is reduced.
Preferably, the biasing member comprises an intermediate between the hammer base and the hammer upper part compression spring. The compression spring is a particularly reliable, inexpensive and easy to set up embodiment of the biasing member.
Preferably, the compression spring is mounted on the retaining bolt. As a result, the compression spring is held and guided particularly reliably, without the need for additional elements must be provided.
Preferably, the chisel assembly is guided in a arranged within the hammer base guide in the direction of impact. The special feature of this invention is that the chisel double impact hammer not only strikes on a wider area (solid and movable part), but it prevents by the extended chisel a drift, which makes the whole impact force act precisely. The efficiency of the chisel double impact hammer is thereby significantly increased compared to a conventional hammer.
Preferably, the chisel double hammer further comprises a handle attached to the hammer base part. Thus, the chisel double hammer can be reliably held by the user.
The invention further relates to a use of a chisel double hammer according to one of claims 1 to 9 as a hand tool, as a chisel in a pneumatic drill or drill with a mechanical or electrical drive.
In the following, the present invention will be further explained with reference to embodiments shown in the drawing. Showing:<Tb> FIG. 1a, 1b <SEP> are plan views of a chisel double impact hammer in an unloaded state and a loaded state, respectively; and<Tb> FIG. 2a, 2b <SEP> Side views of a chisel double hammer each in an unloaded state and a loaded state.
A chisel double hammer 10 consists essentially of a hammer base 12 and a movable hinged hammer shell 14. The hammer shell 14 and the hammer base 12 are movable here in the illustrated embodiment via four retaining pins 16, 16 reliably guided together connected. The retaining bolts 16, 16 hold the hammer shell 14 and the hammer base 12 together, respectively spaced from each other. The retaining bolts 16, 16 are connected to the rear surface of the hammer base 12 fixed to the solid body of the hammer base 12. For this purpose, the retaining bolts 16, 16 can for example be screwed firmly into the hammer base 12, with the four retaining bolts 16, 16 being arranged in the corners of a cross-sectional plane running perpendicular to the direction of impact in the illustrated embodiment variant. The distance between the hammer top 14 and the hammer base 12 is achieved by means of compression springs 18, 18 which bias the hammer base and hammer top of the chisel double hammer hammer apart. For particularly reliable guidance, the compression springs 18, 18 enclose the respective retaining bolts 16, 16.
The chisel double impact hammer 10 further includes a chisel assembly (not shown) received within the hammer base 12 and guided therein, having a plurality of chisels 20-20. In the drawing, on the one hand, the tips of the four chisels 20-20, on the other hand chisel sections 22, 22 between the hammer base 12 and the hammer shell 14 are shown. The two chisel sections of the outer chisels 20 and 20 are covered by the retaining bolts 16 and 16 in FIG. The chisel assembly is connected via four retaining bolts 26 and 26 fixed to the hammer shell 14 so that the chisel assembly follows a movement of the hammer shell 14 in relation to the hammer base 12. More specifically, the chisel assembly is connected to the hammer top 14 such that the chisels 20-20 are substantially retracted into the hammer base 12 in the unloaded condition (see FIGS. 1a, 2a). In the loaded state, or operating state, however, the chisels 20-20 protrude in the direction of impact from a hammer tip 24 of the hammer base 12, as shown in FIG ).
In order to prevent the hammer upper part 14 from separating the retaining bolts 16, 16 and thus from the entire hammer base 12, the retaining bolts 16, 16 at the distal end in each case with a stop 26, 26th Provided to restrict a movement of the hammer upper part 14 in relation to the hammer base 12 to a predetermined maximum distance.
The chisels 20-20 are reliably guided through a respective bore or guide provided in the interior of the hammer base 12 and the hammer top 14, and the chisels 20-20 As far as the hammer tip 24 is concerned, this construction has the result that the chisel double hammer 10 does not only make a normal hammer blow, but when hitting a free space on the workpiece (eg stone) the chisels 20-20 to the next lower place. This is thus effected by the double blow of the hammer upper part 14 on the hammer base 12. Due to the short path of the hammer shell 14 on the hammer base 12 passes to the impact of the chisel 20 - 20 on the workpiece about a maximum of one hundredth of a second.
The chisel double hammer 10 further includes a hammer handle 28 for gripping by the user. The chisel double hammer 10 can be made in any weight class. The shape, whether square, oval, round, etc. is created depending on the application. The special feature of this invention is that the chisel double hammer 10 strikes when hit not only on a wider area (fixed and moving part) but it is also prevented by the extended chisel drifting, which makes the whole impact force act precisely , The efficiency of the chisel double impact hammer 10 is thereby significantly increased over a conventional hammer. An advantage for the manufacturer lies in the simplicity of the chisel double hammer 10. The few items can be relatively easily manufactured and are individually interchangeable when worn. The chisel double hammer 10 is a tool that is suitable for the machining of all hammer-machinable materials, for example, for the machining of stone.
