Definitions

  • the invention relates to the technical sector of hammer-type percussion, concrete breaker, perforator, working with any source of energy, especially compressed air.
  • this type of apparatus has handles of gripping of which at least one is subject to a trigger conformed to act on a device subject to the source of energy that has a part of the body of the device.
  • the handles In an attempt to reduce the significant vibrations resulting from the operation of these percussion apparatus, it has been proposed to suspend the handles relative to the body of the apparatus, that is to say to mount them in an oscillating manner with the ability to angular displacement in the same plane as that defined in the body of the device.
  • the handles are mounted in lateral overflow of the body of the apparatus, in an opposite manner, being substantially aligned.
  • the trigger is carried by one of the handles with which it oscillates so, while the switch to operate for the required power distribution, is integral with the body of the device.
  • the trigger is located above the corresponding grip handle, hence the need to provide a means of locking in order to avoid any inadvertent triggering given the trigger position of the command that is not protected.
  • This obligation to use a means of Intermediate trigger lock generates an increase in weight not insignificant and increases the number of parts needed for the correct operation.
  • the aim of the invention is to remedy these drawbacks, simple, safe, effective and rational way.
  • the problem that the invention proposes to solve is to suppress this intermediate piece of locking avoiding any trigger inadvertent trigger trigger while aiming, to ensure the protection of the user's hands. Indeed, it appears, according to state of the art, that the user's hands are not protected, this which can be important, considering the difficult conditions in which are sometimes used these percussion devices, the hands of the user can be directly exposed with risk of injury.
  • each protective element constitutes a sleeve having a chambering internal shape and section corresponding to those of the handle of gripping.
  • the part of the profiled shape on the side of the body of the apparatus serves as a housing adapted to partially grip the section of said body, said housing having a slot for engagement, overflow and maneuvering the trigger switch, under the handle grasping.
  • FIG. 1 illustrates a non-limiting example of a device of vibration in the form of a breaker hammer.
  • This device includes a body (1) surmounted by a rigid head (2).
  • the head (2) is equipped, in lateral overflow, two opposite handles (3) mounted with capacity oscillation.
  • the head receives a control trigger (4) adapted to trigger at will a power source controlled or not a tool of percussion (not shown).
  • each handle (3) presents, directly or in a reported way, protective elements (5) delimiting a closed space (E).
  • This closed space (E) has the function, on the one hand, to allow the passage and wrapping of the hands of the user in the gripping position of the handles and, on the other hand, the overflow of the control trigger (4).
  • the protective element (5) comprises a body (5a) capable of wrapping, in whole or in part, the section of the corresponding handle (3).
  • the body (5a) constitutes a sheath having an internal chamber (5a1) of shape and section complementary to those of the handle (3).
  • the ends of the body (5a) are joined by a shaped shape (5b) delimiting the space (E) as an under guard.
  • Part (5b1) of the shaped form (5b) located on the side of the body of the apparatus, in particular the head (2) serves as a housing adapted to partially enclose the section of the head (2).
  • the chambering (5a1) of the body (5a) opens at this part (5b1) to allow the introduction of the handles (3).
  • the housing (5b1) has a slot (5c) for engagement, overflow and operation of the control trigger (4).
  • the slot (5c) is established under the recess (5a1) so that the trigger (3) is located under the handle, that is to say under the body (5a), to inside the protection space (E).
  • the entire protective element (5) as defined is advantageously produced by injection of a plastic material. Note that the opposite of the part (5b1) of the profiled form (5b) acting as an under guard, the portion (5b2) at the body (5a) is full. Also note that the shapes of the profiled part (5b) serving as the sub-guard are carefully determined so as not to alter the oscillation of the handles grasping. This is particularly the case with the connection of the lower part of the part (5b3) of the sub-guard with the part (5b1) acting as a crankcase.
  • the gripping system as defined according to the characteristics of the invention can also be completed by a connecting element (7) sectional section for covering the upper part of the head (2) and ensuring a visual connection between two protective elements (5) in particular between the two parts (5b1) acting as crankcase.
  • This connecting element (7) can be independent and reported to be fixed by any known means and suitable for the head (2).
  • connection element (7) is rendered solidary, with articulation capacity, of each of the protective elements (5) in particular at the crankcase portion (5b1), to constitute a unitary whole.
  • the articulated connection between the connecting element (7) and each of the protection elements (5) can be obtained by any means known at the time of molding the whole of the gripping system.
  • the trigger of control can be mounted under one of the gripping handles avoiding thus the use of an intermediate locking part.
  • the trigger is perfectly protected in the defined space. It is the same with regards the hands of the user.
