Definitions

  • the invention relates to an adapter for an additional handle for an electric hand tool according to the preamble of claim 1 and an additional handle with an adapter.
  • Additional handles of the generic type are known. They usually have a single-end releasable attachment option on an electric hand tool device, wherein a fastening device can be provided for attachment to the electric hand tool device between additional handle and electric hand tool. Additional handles allow the user of an electric hand tool device to hold the electric hand tool device while working with both hands and lead. There For example, an additional force in the working direction of the electric hand tool device, for example, a pressing of a hammer drill or a drill in the direction of the longitudinal direction of the drill with an additional handle can be better applied. In particular, by means of additional handles, larger hand tool devices or those which require an increased effort during operation can be operated more simply and more safely.
  • a vibration-damped handle with electric hand tools, which is common especially with angle grinders, which are guided or held by the operator, but do not require additional effort.
  • a portion of the auxiliary handle is equipped with a damping element, whereby the vibrations of the electric hand tool device attenuated transmitted to the handle and thus to the user. This allows a more comfortable and fatigue-free working, as lower vibrations are transmitted to the user.
  • a vibration-damping device for example, from the DE 103 47 944 A1 an auxiliary handle previously known, in which a damping element is provided between the handle member and the fastening device, in which case a stiffener is provided which has a lower deformability than the rest of the damping element.
  • Another additional handle with a damping element between the handle portion and the fastening device is from the EP 1 800 805 A2 previously known, which describes a decoupling device, with at least three mutually spaced parallel rod-shaped decoupling elements.
  • a disadvantage of the prior art is that existing additional handles, such as those in already vibration-damped design for angle grinder present, but also undamped handles, as they are often sold together with electric hand tool, can not be retrofitted with a damping element.
  • an adapter with the features mentioned in claim 1 and offers the advantage that between an already existing conventional auxiliary handle, as used for example as a damped or undamped auxiliary handle for angle grinder, but also other devices and a Fastening means an adapter is interposed, for example, the use of an electric hand tool, in particular one that must be pressed with a certain force in the longitudinal direction of the tool, such as drills, impact wrenches and rotary hammers and chisels and at the same time acts vibration damping.
  • the adapter may allow attachment to a device for which the auxiliary handle was originally designed or for another device.
  • an adapter with an adapter housing, which can be made in particular as a plastic injection molded part, the possibility of the handle in any axial length, wherein the axial direction is the axial direction of the auxiliary handle, to make.
  • the auxiliary handle is usually a substantially rotationally symmetrical component, to which the adapter preferably also connects rotationally symmetrical.
  • the adapter housing may have a conical shape or a conical region which widens from the handle to the fastening device. That is, the adapter housing tapers toward the auxiliary handle.
  • the damping element is formed by a guided in an axial direction between two metal discs cylindrical rubber element.
  • rubber element should also be understood to mean elastomeric elastomers, wherein the damping element is generally designed such that it preferably provides damping in the axial direction, which corresponds to the axial direction of the handle.
  • the damping element may be formed as a compression spring. In particular, this is a rubber compression spring.
  • the actual rubber element between two substantially rotationally symmetrical, in particular circular metal discs is taken and guided. It can the rubber element be connected to the metal discs in any way. In general, plastic discs can be used instead of the metal discs.
  • the power can be absorbed in the damping element uniformly over its entire surface and the force can be introduced over a large area.
  • damping element In principle, more than one damping element can be used.
  • the second fastening means for fixing the adapter to the fastening device for connection to the electric hand tool device can be fixed according to an embodiment of the damping element.
  • the damping element can in turn be fixed to the adapter, so that damping can take place between the fastening device and the adapter.
  • the damping element is connectable via a threaded pin with the fastening device. It can also be provided that the damping element can be connected via a further threaded pin with the adapter housing.
  • bores with an internal thread can be provided both in the fastening device and in the adapter housing into which the threaded pins of the damping element can be screwed.
  • the setscrews can be arranged on the metal discs of the damping element, in particular axially.
  • the applied force should be able to be fully utilized in this direction and not lost in the damping element. It is therefore desirable that the applied force is transmitted directly and the operator receives accurate feedback on the operation in the working direction. At the same time, however, the resulting vibrations to the operator should not be passed on undamped. It is important that there is no tilting substantially dimensions of the auxiliary handle with respect to its longitudinal axis, which is substantially perpendicular to the longitudinal axis of the electric power tool and the tool comes.
  • the longitudinal extent coincides, for example, in a drill of the drill used with the working direction.
  • a rotary hammer for example, a rotary hammer, a chisel or a screwdriver.
  • the damping element is guided radially movably in the adapter housing, that in the axial direction the adapter housing covers the damping element at least partially and in the radial direction has a predetermined defined distance, which allows a certain tilting or tumbling movement of the handle, However, these limits when exceeding a predetermined level. That is, the damping element is at least partially inserted in the axial and radial directions in the adapter housing and enclosed by this. It can be further provided that the damping element in the axial Direction against the adapter housing in particular flush.
  • the fastening device may in particular be non-positively or positively mounted on the electric hand tool device.
  • a fastening device can be provided, which is pushed over the tool chuck of an electric hand tool device and positively or positively fixed on the housing of the electric hand tool device.
  • a tension band may be provided, which can be stretched over a tensioning device so that it can be fixed against twisting and pull-off on the electric power tool housing and does not shift or loosen when the forces occur.
  • a frictional connection will be made here via a frictional connection in the conventional electric hand tool devices and the conventional fastening devices.
  • the fastening device has a collar which covers the adapter in the axial direction at least partially. It is provided that the collar is arranged so that it also partially covers the damping element in the axial direction, wherein between the pointing in the direction of the fastener end of the adapter and the collar in the axial direction, a distance is provided so that in the axial direction an attenuation of the damping element can take place. It can further be provided that between the adapter housing and the collar in the radial direction, a distance is provided.
  • the first fastening means is a bore with internal thread for receiving a threaded pin, which is provided as a fastening element of the auxiliary handle.
  • additional handles are widely used for use in angle grinders, these additional handles can then be screwed directly into the angle grinder housing.
  • the fastening device is preferably releasably attachable to the electric hand tool device. However, it can also be inextricably linked or part of it. Basically, it is also conceivable to design the adapter so that the second fastening means is designed so that it can be attached, for example, directly to a housing, for example an angle grinder, so that by Buffalo of the adapter previously existing additional handles that are especially unattenuated , continue to use and now a damping is provided.
  • the entire adapter in the axial direction has a bore with internal thread into which the threaded pin of the auxiliary handle can be screwed on one side and on the other side of the further threaded pin which is connected to the damping element.
  • the second is located on the damping element arranged threaded pin which can be screwed into a bore of the fastener.
  • the invention further relates to an auxiliary handle with an adapter having the above features, wherein the auxiliary handle via the adapter with a fastening means is connectable for attachment to an electric hand tool.
  • the particular advantage of the invention in addition to the usability of existing additional handles, is that high torques of a hammer drill or drill can be intercepted by a correspondingly secured against tilting damping element and at the same time a simple structure and ease of installation is given.
  • the design of the adapter can be made almost arbitrary and in particular the adapter is variable in length.
  • it can be provided that over the collar, the strap on the gear neck of a hammer drill can be securely attached and tightened.
  • FIG. 1 shows an auxiliary handle 10, which is equipped with a damping device 20, wherein the Additional handle 10 in addition to an attachment region 12, with which he otherwise otherwise directly to an electric hand tool, such as an angle grinder attachable, a handle portion 16 has.
  • the grip region 16 may be formed ergonomically shaped and in particular have partial regions 18 which have a different hardness than the remaining partial region 19.
  • the sub-areas 18 may be formed of a softer, compressible material than the rest of the grip area 19, so that the auxiliary handle 10 provides sufficient stability, the grip areas 18 allow by their elastic Eindgurkle but a secure hold against slipping a user's hand on the handle ,
  • the subregions 18 can be subsequently introduced into the auxiliary handle 10 or sprayed together with the auxiliary handle 10 as part of a 2K spray process.
  • the damping element 20 attenuates substantially in the axial direction, wherein the axial direction is provided with the reference numeral 21.
  • a certain mobility in the direction of tilting or wobble is possible, however, which is largely stabilized.
  • the tilting or wobbling direction is each deviating from the axial direction 21 direction.
  • auxiliary handle 10 has a threaded pin 24 which is attached to the mounting part 12 and can be screwed into an adapter 22.
  • the adapter 22 has cylindrical parts and a conical part, wherein the conical part tapers in the direction of the auxiliary handle 10.
  • the conical part is used for the continuous expansion of the adapter housing 29 to the required diameter for receiving a damping element 28, the in FIG. 2 is shown in an adapter housing 29th
  • the damping element 28 is the same as the threaded pin 24 is set on the auxiliary handle 10 in the adapter 22 via a threaded pin 26 in the adapter 22 in an inner bore of the adapter 22, which is arranged axially screwed. In the axial direction, the damping element 28 bears against the adapter housing 29 with a metal disk 32.
  • the adapter housing 29 is made as an injection molded part and has a rotationally symmetrical design. In this case, it has on its side facing the fastening element 38 a recess into which the damping element 28 is received enclosed in the radial direction, so that the adapter 22 in the axial direction of the damping element 28 extends beyond at least partially.
  • the damping element 28 consists of a rubber-elastic designed as a compression spring element 30 which is guided between two metal discs 32 and 34.
  • On the two metal discs 32 and 34 are each axially arranged threaded pins 26 and 36 are provided, one of which is used for fixing in the adapter housing 29 and the other for fixing in the fastening device 38.
  • the fastening device 38 in this case has a clamping band 40, which (not shown) when setting on an electric hand tool device on the Tool chuck is pushed onto the housing of the electric hand tool device and fixed there.
  • the vibrations arising during operation are transmitted via the clamping band 40 to the rest of the fastening device 38 and thus to the damping element 28 and attenuated by this attenuated and reduced via the adapter 22 to the auxiliary handle 10.
  • the fastening device 38 in this case comprises a collar 44 which at least partially overhangs the adapter housing 29 in the axial direction in the axial direction of the cylindrical section 27.
  • the disc 34 of the damping element 28 is flush against the axial region of the collar 44.
  • a certain tilting or tumbling motion between the fastening device 38 and adapter 22 is possible. However, a greater deflection in a direction deviating from the axial direction 21 is prevented.
