Definitions

the present invention relates to washing guns used in connection with cleaning, distribution of cleansing agents etc. in industry and more particularly to the design and functioning of a hand grip to be used in such guns as set forth in the preamble of claim 1.
a typical washing gun comprises an inlet for the washing fluid, such as for instance water, communicating via suitable intermediary means with a fluid outlet in the form of a nozzle section and a hand grip section somehow provided with a trigger.
the hand grip and the trigger is positioned off the longitudinal axis through the nozzle section so that during operation of the washer, the reaction force on the washer caused by the jet of fluid leaving the nozzle produces a torque, which tends to twist the wrist and forearm of the operator during use of the washer, which is undesired from an ergonomic point of view as it leads to stress and fatigue of the muscles of the wrist and arm of the operator.
a hand spray gun addressing the problem of reducing stress and fatigue of the hand, wrist and arm of an operator during use of the gun is disdosed in JP 08 266956 A.
the hand grip of this gun extends at an angle of between 30 and 60 degrees relative to the longitudinal axis through the nozzle section hereof and the gun is furthermore provided with a finger hooking piece located beneath the nozzle section for supporting the weight of the gun by means of the index finger of the user.
the trigger is not provided with a retainer mechanism, which when desired locks the trigger in the activated position, it is necessary for the operator during use of the washing gun constantly to press the trigger towards the handle portion leading to fatigue of the finger muscles of the operator. Keeping the washer in an open position by means of a retainer mechanism is however not a proper solution for safety reasons, because if the user during a cleaning operation incidentally drops the washing gun, the jet of fluid from the washing gun may cause severe damage, particularly when a high pressure washer is concerned.
EP 0 823 285 A1 discloses a spray nozzle for attachment to a garden hose, the hand grip of which is provided with means for adjusting the spray pattern of the nozzle, blocking the spray of fluid completely in one extreme position and providing different spray patterns at different adjustments of the means on the hand grip.
the gun is provided with releasable means for locking the spray adjustment means in a given position.
the hand grip section extends on either side of a plane containing the longitudinal axis of said nozzle section, so that some of the operators fingers during operation of the washing gun can be placed on one side of said plane, whereas others of the fingers of the operator can be placed on the other side of said plane.
said longitudinal axis through the nozzle section of the washing gun during operation substantially coincides with the longitudinal axis through the forearm of the operator, when the operator during use of the washing gun grips around said hand grip section, thus essentially reducing the torque produced by the reaction force from the washing fluid leaving the nozzle to zero.
the trigger of the washing gun according to the invention is located such that said reaction force from the jet of fluid during operation of the washing gun contributes to the total force necessary to effect a relative displacement between the trigger and the main body of the washing gun, which relative displacement is necessary in order to activate the trigger and to keep this in an activated state during operation of the washing gun.
FIG 1 there is shown a prior art washing gun, generally designated by 1 and provided with a trigger 3 to be activated by the operator during use of the washing gun.
the prior art washing gun is characterised in that the longitudinal axis 2 through the jet and nozzle part of the washing gun does not coincide with the longitudinal axis 4 through the forearm of the operator, but is displaced a distance X from the axis 4.
the reaction force F of the jet during operation of the washing gun produces a torque T resulting in an upward directed torsion of the wrist of the operator, which is undesired from an ergonomic point of view.
the trigger 3 is not provided, with a retainer mechanism, which when desired locks the trigger 3 in the activated position, a solution which as mentioned previously is undesirable for safety reasons, it is necessary for the operator during use of the washing gun constantly to press the trigger 3 towards the handle portion leading to fatigue of the finger muscles of the operator. This required constant activation of the trigger 3 is however not being aided by the reaction force F from the jet.
FIG 2 shows a first embodiment of a washing gun according to the invention.
the washing gun 5 comprises a nozzle section 8 and an inlet 11 for washing fluid.
the hand grip section generally designated by 9 is according to this embodiment subdivided into two sections: an upper section 9" placed above a plane P extending through the longitudinal axis 2 of the nozzle section 8 and a lower section 9' located below said plane P in that part of the hand grip which comprises the trigger 6.
the upper section 9" is shaped to accommodate the index finger of the operator's hand during operation of the washing gun 5.
Figure 3 shows a second embodiment of a washing gun according to the present invention generally designated by 5'.
the fluid jet 7 produces during operation of the washing gun 5 a reaction force F on the nozzle section 8 of the gun 5.
the longitudinal axis 2 through the jet 7 coinciding with the reaction force F is contrary to the case of the prior art washing gun shown in figure 1 coincident with the longitudinal axis through the forearm of the operator.
This is accomplished by positioning the hand grip section 9 substantially symmetrically with said longitudinal axis 2 through the nozzle section 8
the trigger could in principle be placed anywhere on the hand grip section 9, 9', for instance on that part of the hand grip section 9 facing the nozzle section 8, which position would correspond somewhat to the position of the trigger in the prior art washing gun 1 shown in figure 1.
