Definitions

  • the invention relates to a device for extending a tilting joystick for controlling an electrical appliance capable of being fixed to the end of the joystick to increase its height.
  • a device of this kind is known from document BE-B-1 006 483.
  • the device described in the above document comprises a part intended to be mounted to slide on the handle of a switch, said handle having a square section.
  • the part is fixed to the handle or by means of a disc which expands radially against the internal walls of the part when a screw is tightened.
  • the tilting operating levers for miniature circuit breakers are relatively short, and it is quite difficult to operate them.
  • the present invention relates to an extender making it easier to grip the handle and incidentally to individualize the circuit breakers by allowing the attachment of a label on the extender.
  • the device according to the invention is characterized in that it comprises an extension bar made of rigid plastic material having an H profile, the base of which is capable of being engaged overlapping and clipped onto said end by bending of the core of reduced section of the H-shaped profile, and a locking key capable of being engaged in the upper part of the H-shaped profile to oppose any bending of the core of the profile and to lock the bar on the handle.
  • the use of a rigid material avoids any deformation under the maneuvering force and the particular shape of the bar allows a deformation or the latching of the extension from the front, any deformation being subsequently prevented by the insertion of the locking key.
  • Mounting from the front allows snapping onto a handle of a circuit breaker fitted with an auxiliary block, in particular a differential protection block, the profile of which protrudes and prevents sliding of the extension cable from the side on the handle.
  • the lever may have original projections or ribs for clipping or latching of the extension bar, or according to a preferred embodiment, the latching is carried out on a coupling bar of the levers of the different poles of a multipole circuit breaker, said bar constituting an additional thickness or a bulge at the end of the levers.
  • Another object of the present invention is to allow the individualization of circuit breakers by attaching a label.
  • the label is inserted in the upper part of the bar and is locked or held by the locking key inserted in the mounted position in the upper part of the profile.
  • the locking key is made of a transparent material, and according to a development of the invention, it is shaped like a magnifying glass facilitating the reading of the label.
  • the locking key matches the external profile of the bar in the mounted position, so as to constitute a one-piece assembly rigidly secured to the handle of the circuit breaker. In the mounted position, any lateral movement of the extension is prevented by the tightening force exerted on the lever.
  • the extension can be dismantled by removing the locking key and subsequently by pinching the upper part of the profile, tending to spread the tabs surrounding the handle.
  • a bipolar circuit breaker 10 constituted by the assembly of two poles each having a lever 12, 14 for operating, has a U-shaped coupling bar 16 fitted on the ends of the levers 12, 14 to allow control simultaneous by tilting of the handles 12, 14 of the poles of the circuit breaker 10.
  • the coupling bar 16 of iron U fitted on the handles 12, 14, constitutes a bulge or an additional thickness at the edge of the handles 12, 14.
  • the extension device or extension designated by the general reference 18, comprises a bar 20, constituted by a generally H-shaped section and a locking key 22.
  • the H-shaped section 20 has at its base two tabs 24, 26 capable of fitting onto the levers 12,14 and the coupling bar 16.
  • the legs 24, 26 have a reduced spacing at the base corresponding substantially to the thickness of the levers 12, 14, but less than the bulged part constituted by the coupling bar 16 ( see fig. 2).
  • the bar 20 is made of a rigid plastic material, for example a reinforced polycarbonate resin, and the connecting core or bridge 28 between the two branches of the H-shaped section is of a thickness that is sufficiently thin to give a certain sufficient flexibility to spacing of the tabs 24, 26 for snap-fastening on the lever assembly 12,14 - coupling bar 16.
  • the deformation of the bar 20 can be carried out by pinching its upper part tending to bring the two branches together and to bend the 'soul 28 to spread the lower legs 24, 26.
  • the bar 20 is locked in position mon ted on the levers 12,14 by insertion between the branches 32, 34 of the upper part of the bar 20, of a locking key 22 filling the gap formed between the branches 32, 34.
  • the locking key, shaped plate of a width corresponding to the spacing of the branches 32, 34 in the mounted position of the bar 20, is maintained in the mounted position by the snap-fastening of two end tabs 36, 38 with projections 40 in recesses 42 formed in the internal face of the branches 32, 34.
  • the locking key 22 is made of a rigid material, for example identical to that of the bar 20 and the elasticity necessary for the latching of the legs 36, 38 is imparted by a groove 44 , formed in the legs 36, 38.
  • the locking key 22 is made of a transparent material and is shaped to present a convex upper face and a concave lower face with a radius larger than that of the upper face, the combination of the two faces thus constituting a bar with magnifying glass effect.
  • the ribs 46, 48 constitute a support for a label 50 in the form plate placed on the edges of the ribs 46, 48 and capped by the locking key 22 in the mounted position of the latter. It is easy to see that the label 50 is retained by the two internal edges of the locking key 22, which makes it easier to read by the magnifying glass effect described above.
  • the length of the label 50 is less than the spacing of the tabs 36, 38 between which it fits.
  • the extension device according to the invention is implemented in the following manner:
  • the extension 20, 22 is delivered as a spare part, the length corresponding to the standard lengths of the coupling bars 16.
  • the bar 20 For the installation of the bar 20 on the lever assembly 12, 14 - coupling bar 16, it suffices pinch the upper arms 32, 34 and snap the bar onto the coupling bar 16 and the levers 12,14, the mounting being facilitated by the bending of the core 28 of the bar 20.
  • the bar 20 can of course be slid from the side onto the lever assembly 12, 14 - coupling bar 16, the sliding being possibly facilitated by pinching the upper branches 32, 34.
  • the bar 20 being latched, the label 50 is placed on the supports 46, 48 and the locking key 22 is latched between the arms 32, 34 of the upper part of the bar 20.
  • the locking key 22 locks the bar 20 on the levers 12, 14 preventing any lateral sliding or any tearing of the extension 20, 22, in particular during an operation or a sudden trip of the circuit breaker.
  • the locking key 22 is positioned laterally by the ribs 46, 48 engaged between the tabs 36, 38.
  • the label 50 can be read with an enlargement through the magnifying glass formed by the locking key 22.
  • Disassembly is carried out by a reverse operation of removing the locking key 22, in particular by inserting a tool for tightening the tabs 36, 38.
  • the bar 20 can be torn off by pinching the upper branches 32, 34.
  • the height of the bar 20 corresponds of course to the desired extension, and the length of the extension 20, 22 corresponds to that of the lever or more exactly of the coupling bar 16 of the levers 12, 14 It is clear that the extender according to the invention can be used on levers without a coupling bar, but shaped to have a bulged end or snap-in recesses of the snap-on parts 24, 26 of the strip 20 .
