Definitions

the invention relates to the technical sector of percussion devices of the jackhammer, concrete breaker, perforator type, operating with any energy source, in particular compressed air.
this type of device has grips, at least one of which is subject to a control trigger configured to act on a device subject to the source of energy that a part of the body of the 'apparatus.
the handles are mounted in lateral overflow from the body of the device, in an opposite manner, being substantially aligned.
the trigger is carried by one of the handles with which it therefore oscillates, while the switch to be actuated for the distribution of necessary energy, is secured to the body of the device.
control trigger is located above the corresponding grip handle, hence the need to provide a locking means in order to avoid any untimely triggering given the positioning of the trigger. command that is not protected.
This obligation to use an intermediate trigger locking means generates a significant increase in weight and increases the number of parts necessary for proper operation.
the object of the invention is to remedy these drawbacks in a simple, safe, effective and rational manner.
the problem which the invention proposes to solve is to eliminate this intermediate locking piece while avoiding any untimely triggering of the control trigger while having the objective of ensuring the protection of the hands of the user. Indeed, it appears, according to the state of the art, that the user's hands are not protected, which can be important, if we consider the difficult conditions in which these devices are sometimes used. impact, the user's hands may be directly exposed with risk of injury.
a gripping system of a percussion device in particular comprising handles mounted with capacity for articulation relative to the body of the device, one of the handles being equipped with a control trigger acting on an energy source, remarkable in that each handle has, directly or in a reported manner, protective elements delimiting a closed space for, on the one hand, the passage and the 'wrapping of the user's hands in the gripping position of said handles and, on the other hand, the overflow and the operation of the control trigger, under the gripping handle, inside said space.
each protective element comprises a body capable of enveloping, in whole or in part, the section of the handle. corresponding, the ends of said body being joined by a profiled shape delimiting the space by acting as a sub-guard.
each protective element constitutes a sheath having an internal recess of shape and section corresponding to those of the handle. gripping.
the part of the profiled shape located on the side of the body of the device acts as a casing capable of partially enclosing the section of said body, said casing having a slot for the engagement, the overflow and the operation of the control trigger, under the grip handle.
the gripping system according to the invention finds a particularly advantageous application in the case where the device comprises two opposite handles mounted articulated on either side of a head which has the upper part of the body of the device.
the head is capped by an element capable of ensuring the visual connection between the two parts serving as a housing.
either the connecting element is made integral with the ability to articulate the protective elements, in particular of the part serving as a casing, so as to constitute a unitary assembly.
FIG. 1 is a perspective view of an example of a percussion device equipped with the gripping system according to the invention ;
- Figure 2 is a perspective view of one of the protective elements of the system;
FIG. 3 is a longitudinal sectional view showing the mounting of the gripping system relative to the handles;
FIG. 4 is a cross-sectional view taken along line 4-4 of Figure 3.
FIG. 1 Illustrated in Figure 1, a non-limiting example of a vibration device in the form of a concrete breaker hammer.
This device comprises a body (1) surmounted by a rigid head (2).
the head (2) is equipped, in lateral overflow, with two opposite handles (3) mounted with oscillation capacity.
the head receives a control trigger (4) capable of triggering an energy source at will with or without the command of a percussion tool (not shown).
each handle (3) has, directly or in an attached manner, protective elements (5) delimiting a closed space (E).
This closed space (E) has the function, on the one hand, of allowing the passage and envelopment of the hands of the user in the gripping position of the handles and, on the other hand, of allowing the control trigger to overflow (4).
the protective element (5) comprises a body (5a) capable of enveloping, in whole or in part, the section of the corresponding handle (3).
the body (5 a) constitutes a sheath having an internal recess (5al) of shape and section complementary to those of the grip handle (3).
the ends of the body (5a) are joined by a profiled shape (5b) delimiting the space (E) by acting as a sub-guard.
the recess (5al) of the body (5a) opens at this part (5bl) to allow the introduction of the handles. (3).
the housing (5bl) has a slot (5c) for engagement, overflow and operation of the control trigger (4).
the slot (5c) is established under the recess (5al) so that the trigger (3) is located under the grip handle, that is to say under the body (5a), inside protective space (E).
the whole of the protective element (5) as defined is advantageously produced by injection of a plastic material.
the part (5b2) opposite the part (5b 1) of the profiled shape (5b) acting as a sub-guard, is full.
the shapes of the profiled part (5b) acting as a sub-guard are judiciously determined so as not to alter the oscillation of the handles gripping. This is particularly the case at the connection of the lower part of the part (5b3) of the sub-guard with the part (5b 1) acting as a casing.
the gripping system as defined according to the characteristics of the invention can also be completed by a connecting element (7) profiled in section to cover the upper part of the head (2) and ensure a visual connection between two protective elements (5) in particular between the two parts (5b 1) serving as a housing.
This connecting element (7) can be independent and attached to be fixed by any known and appropriate means at the level of the head (2).
control trigger can be mounted under one of the grip handles, thus avoiding the use of an intermediate locking piece.
the trigger is perfectly protected in the defined space. The same applies to the user's hands. The advantages are apparent from the description.
