Описание
  • The invention relates to a holding element arrangement for a portable hand machine, in particular drill or angle grinder, with a trained for attaching a tool main body.
  • Such hand machines are well known in the art. They usually have a handle formed on the main body which can be grasped with one hand, and a cylindrical holding element which is arranged at a distance from the handle on the main body of the hand machine.
  • The invention has for its object to design a generic portable hand machine so that it can be held by a user with one arm and this at least the fingers of both hands to perform activities, such as the attachment of gypsum boards, boards or the like, free ,
  • To achieve the object, it is provided that the holding element arrangement comprises a first holding element and a second holding element, which are fixed to the main body, wherein the first holding element and the second holding element are arranged one behind the other and designed such that the first holding element with a hand of a Poor of a user is umgreifbar and the second holding element encloses a lower arm of the same arm of the user at least partially. Further advantageous embodiments of the invention will become apparent from the dependent claims.
  • This configuration of the second holding element and the arrangement of the two holding elements relative to each other makes it possible for a user to safely carry the hand-held machine according to the invention on a forearm and nevertheless use the fingers of the hand of the forearm to perform activities without laying aside the hand-held machine to have to. For safety reasons, the latter of course only comes into consideration when the hand machine is deactivated. For example, boards, slats or plates can be maneuvered without having to put the hand machine aside. It is also possible to use secondary tools such as spirit level, angle or pen without having to put the hand machine aside. This is particularly advantageous in hand machines such as drills or angle grinders (so-called flex). So far, users make do with the fact that they clamp such a hand machine between the thighs in order not to have to put aside. This is superfluous by the invention, which not only makes it easier for users to perform an activity but also increases the safety at work. The invention thus has two essential aspects, namely, on the one hand the arrangement of the two holding elements to each other and on the other the formation of the second holding element such that it at least partially surrounds a forearm of a user, so at least partially surrounds it, so that the hand machine on the forearm the user is fixed.
  • It may be provided that the holding element assembly comprises a base body which is fastened to the main body of a hand machine via a plug, screw, or clamping connection and to which the first holding element and the second holding element are attached or formed. This embodiment makes it possible for a hand machine, on the main body of which initially not the first and the second holding element are arranged, to be equipped with the holding element arrangement according to the invention. The main body of the hand machine can have corresponding fastening means for this purpose. By means of a clamping connection, however, an attachment of the retaining element arrangement can also take place without such corresponding fastening means.
  • Preferably, the first holding element and / or the second holding element are formed closed. Closed means in this context that the holding elements are connected on both sides with the main body of the hand machine, for example in the form of a loop made of a flexible material which is attached to both sides of the main body, or have a breakthrough, so that the forearm of a user's arm or the Finger of a hand can be inserted through the holding elements. The second holding member then fixes the hand machine to the forearm of a user while the first holding member is gripped with fingers and thumbs of the hand of the same arm, and the hand machine can be so securely guided and used for its intended use.
  • The second holding element may consist of an elastically deformable material and be formed for example as a belt loop, which in addition the formation of pressure points on the forearm of a user is prevented.
  • Furthermore, it can be provided that the first holding element and / or the second holding element have an opening mechanism. In this embodiment, the first holding element and / or the second holding element are indeed formed closed, but can be opened. For this purpose, an opening mechanism may be present, which connects two sections of a holding element with each other. In this opening mechanism can it can be a Velcro or a button closure. Of course, other opening mechanisms are possible. The choice for an opening mechanism can be selected depending on the type of hand machine and the force applied to the holding elements in the intended use of the hand machine.
  • In an advantageous embodiment, the first holding element recesses for receiving fingers of the user's hand. These recesses lead to a pleasant embrace of the first holding element and thus increase the ease of use of the hand machine. Said depressions may be arranged on a surface of the first holding element facing away from the main body and possibly also extend around the holding element. However, the surface of the first holding element facing the main body should be made smooth, since the palm of the user rests there and recesses located there have led to unpleasant pressure points on the palm of the user.
  • In a particularly preferred embodiment of the hand machine according to the invention at least one switch is arranged on the first holding element, by means of which the hand machine can be activated. Preferably, the switch is arranged on the first holding element such that it can be actuated with a thumb of the user's hand. Of course, it can also be arranged so that it can be operated with one finger of the user's hand. These embodiments have the advantage that the hand machine can be activated and deactivated with the hand of the same arm, with which it is listed in the application. The switch may be designed such that it has only one rest position in which the hand machine is deactivated. This can for example take place in that the switch is designed as a resilient push button, wherein the hand machine is activated when the push button is pressed and this automatically moves to its rest position as soon as no pressure is exerted on him, so that the hand machine automatically disabled when the push button is released. In the embodiment of the holding element assembly with basic body, which is attached to the main body of a hand machine, of course, an electrical connection between the switch and the tool driving the electric motor must be present. For this purpose, the base body may have electrical contacts which contact corresponding electrical contacts on the main body.
  • It can further be provided that the tool can be fastened to the hand machine so that it can rotate about an axis, and the first holding element is arranged on an imaginary extension of the axis. This embodiment lends itself to disk-shaped tools which rotate upon activation of the hand machine. Characterized in that the axis of rotation of the tool and the first holding element are arranged in a line, the hand machine can be easily and accurately performed in use.
  • In a further embodiment, it may be provided that the holding element arrangement comprises a third holding element, which encloses substantially a right angle with the first holding element. In this embodiment, in addition, the hand of the second arm of the user for a stable guidance of the hand machine can be used in case of need. Such a holding element is basically known from the prior art and has a substantially cylindrical shape, so that the third holding element can be gripped by the hand of an arm. Of course, the third holding member may also have deviations from the cylindrical shape, as is common in handles of tools, for example by depressions for receiving fingers of one hand, etc.
  • The invention will be explained in more detail with reference to figures.
