Definitions
- the present invention relates generally electrical apparatus or apparatus of the kind comprising a mechanism with which it is associated for its control a pusher mounted axially movable, a support, the mechanism of which is united, and which, in practice, is intended to bear against a any bearing surface by at least a portion of its periphery, a plate, which, attached to the support and surrounding it at least partially, is it likely, in practice, to bear on the same bearing surface that this support or on a support surface substantially parallel to it, and a touch of maneuver, which at the available to the user, is movably mounted on the plate, being for example pivotable thereon, and is thus suitable act, either directly or indirectly, on the mechanism control.
- the bearing surface against which is brought to bear their support is usually directly formed by the bare wall.
- the adjustment screw that constitutes this threaded rod is a conventional screw, i.e. a screw whose the pitch is relatively reduced, and in any case sufficiently weak so that any simply axial action to which it could be subject is not likely to induce one any rotation.
- the adjustment to be made can only be executed blind, its verification requiring to proceed then reassembly of this device.
- the present invention generally has for subject a provision which, relatively simply, advantageously avoids these drawbacks.
- the threaded rod of the pusher is permanently the object of a couple of unscrewing systematically ensuring that any axial play is taken up possible between the push-button and the operating button, however that, as is the rule, any pushing force exerted on this operating key is duly transmitted axially by the pusher to the underlying mechanism, for the command of it.
- any possible impact on the operating button is advantageously likely to be best supported by the pusher, without destroying the thread of its sleeve, this shock which can at most lead to momentary depression in this sleeve of the threaded rod which is engaged with it.
- the electrical apparatus 10 comprises, overall, in a known manner in itself, a mechanism 11, with which it is associated, for its control, a pusher 12 mounted axially movable, a support 13, of which the mechanism 11 is integral, a plate 14, which, attached to the support 13, surrounds at least partially this one, and a touch of maneuver 15, which, available of the user, is mounted mobile on the plate 14 and is suitable for act, either directly or indirectly, on pusher 12.
- the apparatus electric 10 is an electronic switch
- the mechanism 11 is controlled by a microswitch 16.
- the mechanism 11 comprises a lever 21, which, by means of ears 22 implanted along one of its edges, is pivotally mounted on pins 23 provided for this purpose on the cover 19, and against the central part of which bears, according to provisions described in more detail later, the pusher 12.
- lever 21 has, laterally, tabs 24 which engage in the cover 19 thanks to recesses 25 provided for this purpose on this one, and by which he is able to hook himself on this cover 19.
- the following electrical appliance 10 the invention is also intended to be embedded in a wall 27, or, more exactly, in a recessed box, not shown, housed for this purpose in a recess 28 of this wall 27.
- the support 13 that this electrical device 10 comprises is therefore suitable to be attached to the installation box thus implemented, for example by screws not shown. To this end, it has holes 29.
- the support 13 does not by itself fall under the present invention, it will not be described in all its details here.
- the cover 19 of the mechanism 11 has, in opposite positions relative to each other, two hooks 32 by which it is able to engage with notches 33 provided in correspondence for this purpose at the edge of the recess central 31 of support 13.
- the plate 14 completely surrounds the support 13, and thus extending beyond of this support 13 at its periphery, it is likely to come wear either on the same bearing surface 30 as him, as shown in Figure 1, either, as shown in the Figure 10, on a bearing surface 30 ', which, substantially parallel to the bearing surface 30, is formed by a coating 35 attached to the wall 27 around the support 13.
- the plate 14 is able to be attached by screws, not shown, on the support 13.
- the support 13 comprises wells 37.
- the operation 15 is housed in a central recess 38 of the plate 14 at the edge of which the ears 36 of the latter intervene, and it is pivotally mounted on this plate 14.
- the operating button 15 comprises, laterally, to do this, ears 40 by which it is snapped onto pins 41 provided at correspondence to this effect on plate 14, at the edge of its central recess 38, between his ears 36.
- the pusher 12 comprises two parts in screwing relationship, one relative to the other, namely, on the one hand, a sleeve 12A, which is locked in rotation while being axially movable, and whose internal bore 42 is tapped, and, on the other hand, a threaded rod 12B, which is screwed in with the sleeve 12A.
- the thread (s) 43 that present the threaded rod 12B of the pusher 12 are threads with large pitch P, according to arrangements described in more detail later, and jointly the threaded rod 12B is subjected to elastic return means 44 tending to permanently extract it from the sleeve 12A with which it is in taken.
- the sleeve 12A is intended for controlling the mechanism 11, by action on the microswitch 16 controlling it, and, more precisely, on the lug 17 of this microswitch 16, while the threaded rod 12B is intended for the action of the operating button 15.
- the sleeve 12A therefore extends on the side of the mechanism 11, and the threaded rod 12B on the side of the operating button 15.
- the sleeve 12A has a blind bottom 46, and it is by this that it is able to act on the lug 17 of the microswitch 16.
- the sleeve 12A which is generally cylindrical, has, externally, a circular cross section.
- a stop collar 48 projecting from the side of the microswitch 16, but slightly set back from its blind bottom 46, a stop collar 48, for cooperation in abutment with the corresponding section 49 of the socket 20 in which it is engaged.
- This stop collar 48 which for reasons space has, externally, in the embodiment shown, a particular contour, locally presents a notch 52, for sliding engagement on an extension local 53 of the socket 20 intended to ensure blocking in rotation of the sleeve 12A on the mechanism 11, and, therefore, its locking in rotation relative to the threaded rod 12B.
- the outer edge of the sleeve 12A is cut down by a chamfer 54, to facilitate its engagement in the socket 20.
- the sleeve 12A has, in its internal bore 42, equal number of helical grooves 55 to that of the threads 43 of the threaded rod 12B.
- the rod threaded 12B has indeed several threads 43, in this case four, and therefore the sleeve 12A has four internally helical grooves 55, which, of course, all identical between them, are complementary, each respectively, of threads 43 of the threaded rod 12B.
- the pitch P of the threads 43 of the rod 12B thread is preferably greater than 1.5 times the diameter D of this threaded rod 12B, measured externally, on the crest of these nets 43.
- the pitch P being in practice greater than the height H of the threaded rod 12B in the embodiment shown, one of the nets 43 has been extended in broken lines on the Figure 5 so that it can be duly identified.
- the pitch P of the threads 43 of the threaded rod 12B is substantially equal to 2.5 times the diameter D thereof measured in the conditions previously specified.
- the nets 43 of the threaded rod 12B have a trapezoidal profile, and, more precisely, an isosceles trapezoidal profile whose sides or sides 56 form an angle A greater than 90 ° between them. For example, this angle A is close to 100 °.
- any other profile could agree, while preferably being symmetrical.
- the threaded rod 12B has a head 57 on which the elastic return means 44 associated therewith.
- these elastic return means 44 are constituted by a spring, of the coil spring type, which is generally frustoconical, and which rests on the cover 19 of the mechanism 11, around a centering bead 58 which, in protrusion on this cover 19, in practice forms an extension of the sleeve 20 which the latter comprises.
- the head 57 of the threaded rod 12B is smooth.
- the threaded rod 12B is preferably made of metal.
- the threaded rod 12B is permanently the object of a loosening torque, which tends to extract it from the sleeve 12A, in the direction of the operating button 15.
- the sleeve 12A of the pusher 12 is remote, but very short distance, from the lug 17 of the microswitch 16, which, from therefore, is in a first state.
- the operating key 15 is the object of an action tilting, it is the same for lever 21 of the mechanism 11, and, as shown schematically by the arrow F2, opposite in the previous one, in FIG. 9, the threaded rod 12B of the pusher 12 according to the invention is then the object, against of its elastic return means 44, of an action of depression during which it drives axially it and therefore causes its action on lug 17 of the microswitch 16, which therefore switches to its second state, distinct from the previous one.
- the wall 27 carries a coating 35 forming a surface support 30 'for the plate 14 around the support 13.
- the operation of the device electric 10 according to the invention is indifferent to the thickness of the coating 35 possibly present on the wall 27.
- the present invention is not limited to the embodiment described and shown, in particular in regarding the number of threads of the threaded rod of the pusher according to the invention and / or the profile of these nets, but encompasses any variant embodiment according to the claims.
- the rod threaded has at least one thread.
