Description

CONTROL HANDLE.

  The invention relates to a particular control handle

for electric control.

  It is already known, in the prior art, to nominate

  many forms of execution of electric control handles

  usually called pendant boxes with buttons or pushers intended to allow the remote control of machines, apparatus, tools (cranes,

  pallets, cranes, gantries, winches, gallows etc).

  However, these known control handles are inconvenient in particular because the manipulators who use them are usually obliged to hold the handle with one hand and press the electrical control pushbuttons on the handle, the other hand The manipulator has both hands occupied which does not allow him to perform any manipulations

  In addition, the

  Known products do not have a sufficient degree of security and as a result the control push-buttons

  may be active even though

  In the known control handles, the manipulator must, to carry out the commands, move the whole of the hand pressing the control push-buttons.

compared to the handle.

  The invention aims to overcome these disadvantages.

  A first object of the invention is therefore to provide a control handle, particularly for electrical control, which can be used only with one hand, that is to say, not requiring to be held with one hand while that the fingers of the other hand operate the

  control pushbuttons Another purpose of the invention

  is to offer a safety control handle

  particularly as soon as the manipulator

  to maintain the handle, no command can be

  A third object of the invention is to propose

  a control handle whose handling is particularly easy, while being very safe.

  To achieve these goals, the control handle

  the invention comprises temporary association means

  the manipulator's hand-held handle having the function of physically associating the handle with the hand of the manipulator, while freeing the fingers from the hand of the manipulator holding the handle; and

  particular control means such as buttons

  pushers, actuated by the fingers of the hand of

pulateur, associated with the handle.

  This control handle may comprise general means

  with the function of commissioning

  generally of the particular control means, ac-

  as soon as the manipulator's hand is

  held together or pressed against the handle and,

  milking, inactive when the hand is cleared ie

  dissociated or loosened handle, the means of com-

  individuals who can not be made active until

  that they are actuated and simultaneously when the

  General control means are active.

  This embodiment of a control handle of this type is particularly advantageous because it avoids

  accidents By simply opening the hand and sliding

  The handle has an ergonomic shape adapted to the hand of the user The general control means are protected by the shape of the hand, the handle is released from the hand of the user.

general given to the handle.

  The following description with reference to the attached drawings

  as a non-restrictive example

  invention and how it can be put into practice.

tion.

  FIG. 2 is a perspective view, on the opposite side,

of the handle of Figure 1.

  The invention relates to a control handle 1, in particular

  electrical control system which includes

  of association 2 of the handle I by hand 20 of a hand

pulateur.

  The hand 20 is shown schematically in phantom.

  His thumb, his index finger, his middle finger, his ring finger and his little finger are referenced respectively 19, 21, 22, 23 and 24 The palm and the back of the hand are referenced respectively 25, 26 According to the invention, the hand 20 all to both holds the handle I and can manipulate the control means such as pushbuttons it comprises. The means of association-2 have the function of achieving the temporary physical association of the handle I by hand 20 while releasing the fingers 19, 21, 22, 23, 24 which can be used for the control. Preferably, the control handle 1 also comprises general control means (on-or-off) allowing the general operation of the means

particular control devices 4, 8.

  The general control means 3 are active as soon as the hand 20 is kept associated with or pressed on the control handle 1; and inactive when the hand 20 is disengaged, that is to say dissociated or loosened

of the control handle 1.

  When the rear control means 3 are active, the particular control means 4, 8 may be

  rendered active if they are activated On the contrary,

  that the general control means 3 are inactive, the particular control means 4, 8 are and remain

  inactive even if they are operated.

  Preferably, the general control means 3 are made active by a part of the hand 20 other than the fingers. For example, the general means of

  command 3 are made active by the palm 25.

  Finally, the control handle I comprises means of

  particular control 4, 8 in the form of buttons

  pushers, operated by the fingers 19,21, 22, 23, 24

252.8594

  of the hand 20, especially the ends of the fingers.

  Preferably, the control means 3, 4, 8

  All or none of these control means are associated with electrical switches. Feedback means request these electrical switches and the control means 3, 4, 8 to their inactive state for safety reasons. The control means 3, 4, 8 can have two contacts, one contact being

offset from each other.

  Means of association 2 include means for blocking

  unidirectional cage 5 and means of blocking

  upper unidirectional cage 6 opposed the means of

  blocking 5 and above 6 include

  curved guettes Sa, 6 a, joined together by

  their base to horizontal unidirectional blocking means

  The tongues 5a, 6a are concavely curved towards each other and towards the locking means 7. In their middle part and towards their close base of the locking means 7, the tongues 5a and 6a are spaced from each other by a distance at least equal to the spacing between the two cutting edges of the hand 20 at the level of the palm 25,

  so that the hand 20 can be placed in the box.

  defined by the tabs 5a, 6a and the means of

  blocking 7 The distance between the two ends

  2 of the two tabs 5a, 6a is lower, so as to constitute a transverse horizontal blocking

  acting in the opposite direction to the means 7.

  Thus, the hand 20 is blocked horizontally and trans-

  towards the outside of the handle, in the direction

  of the arrow FI, by the tongues 5 a, 6 bent.

  The hand 20 comes into block vertically and downwards in the direction of the arrow F 2 thanks to the tab which comes into lock on the outer edge of the hand The hand is blocked vertically and upwards in the direction of the arrow F 3 by the tongue 6 a which

  just block on the inside edge of the hand at-

  holding the thumb Finally, the hand is blocked horizontally

  transversely and towards the handle itself

  Alternatively, the tongues 5a, 6a are joined to each other and form a kind of arch for the passage of

  The hand locking means 20 does not prohibit

  do not feel the easy and quick separation of the hand 20

and the handle 1.

  In all cases, the hand 20 can not be introduced into the housing formed by the locking means 5, 6, 7, that is to say cooperate with the handle I to be associated with it, that by axial sliding of the

hand.

  Thus, the automatic orientation of the handle is ensured,

  which avoids any error on the part of the manipulator.

  The locking means 7 on which is intended to come to rest the palm 25 of the hand 20 are constituted by a protruding side 7b of a middle part

  7 is generally at least substantially pseudo-cylindrical

  The protrusion 7b, placed between the tongues a, 5b is convexly turned towards the concavity of the tongues.

  Thus, the set formed by the languets-

  Sa, 6a and the outgrowth 7b is elevated in shape

  Preferably, the general control means 3

  are located at or near the excrescence

  ance 7b so that the hollow or the triangle of the hand comes to apply on it when the user grasps

the handle.

  The middle portion 7 has, on the opposite side to the means 3 in relation to the axis XX, at least one or a first series of control means 4, for example four control means in the form of push-buttons 11, 12, 13, 14 on which can be placed the fingers 21,22,23, 24, of the hand 20 of the user when holding the handle 1 Preferably, the push buttons 11, 12, 13, 14 are placed in the normal position the end of the fingers 21, 22, 23, 24 of the hand 20

  Preferably, the push-buttons 11, 12, 13, 14 are placed on a generator D 1 of the median portion 7 a, while being more or less regularly spaced apart.

others.

  It goes without saying, as a variant, that it is possible to predict

  a different number of push buttons depending on

  For example, the pushbuttons may concern only certain fingers Also, for the same finger it can be provided several push buttons (for example two) spaced along the generator Dl

  or preferentially along a perpendicular curve

  As a variant, all or part of the generator

  control means 4 may not be buttons

  pushbuttons but sliding buttons for example along curves perpendicular to the generator DI Each push button can actuate two staggered contacts

relative to each other.

  The middle part 7 a is connected to the base of the lan

  The joining portion 27 carries, near the edge of the base of the tongue 6a, which cooperates with the junction of the thumb 19 and the upper edge of the hand 20, control means 8 or a series of control means 8 , for example two push buttons 9, 10 arranged on a line D 2 forming an acute angle α with the line DI of about 30 The control means 8 are intended to be actuated by the thumb, in particular by pivoting As mentioned above, the

  so possible in a few seconds.

  The control handle I comprises means 15, 16, 17, 18 whose function is to respectively receive the index finger, the middle finger, the ring finger and the little finger 21, 22, 23, 24 of the hand 20, so that these fingers are placed in the proper position to be able to act on the control means 4 These means 15, 16, 17,

  18 consist of grooves formed in the

  median tie 7a, substantially parallel to each other, and

  less substantially perpendicular to the axis XX.

  and associated with the control means 3, 4, 8.

  By virtue of its embodiment, the control handle I can be dissociated from the plug 29 associated with the cable 30 or, on the contrary, installed very rapidly on a cable.

such sheet.

  The control handle I according to the invention is used

  in the following way: the manipulator engages axially-

  the hand of manipulation in the bounded space

  by the tabs 5a, 6a and the protrusion 7b, the

  25 being turned towards the protrusion 7b until the thumb 19 locks on the base of the tongue 6a Except to perform a relative sliding of

  the handle I with respect to the hand 20 in the oppo-

  se, the handle I is physically associated with the hand 20.

  The manipulator can seize the handle by closing the hand on it and by applying the palm 25, especially the palm of the hand, on the protrusion 7 bo are the general control means 3 The general control means 3, previously inactive are made active, which will make it possible to make active the other particular control means 4, 8 These particular control means are made active by the action of the fingers

19, 21, 22, 23, 24 of the hand 20.

  If the manipulator leaves the handle I without holding it, the control means 3 return to their inactive state so that even in case of inadvertent manipulation on the control means 4, 8 nothing happens.

  It should be noted that there can be no maneuver

  pestive on the general control means 3 to make them active given that these control means 3 are protected being housed in the hollow formed

by the tabs 5a, 6a.
