Definitions

  • the present invention relates generally to portable lamps, that is to say electric lamps which, arranged at the end of a wire of suitable length, can be moved by hand by their user, at the discretion of the user. ci (see for example US patents 1,411,209 and FR 1,140,769).
  • the protective basket is usually made to today welded metal and comprises a fixing collar, formed of an open strip to be closed by one or more screws on the grip handle, and a son superstructure, carried by said collar.
  • This assembly is therefore relatively long, delicate and expensive.
  • the protective basket can be removed from the handle, to the detriment of safety.
  • Such a portable lamp which implies a specific embodiment for the socket and the handle, cannot be suitable for all use cases.
  • the present invention generally relates to the extension to other types of portable lamps of an embodiment with a closed clamp on itself continuously of the protective basket, and therefore, if desired, of a homogeneous production entirely of wires of such a protective basket.
  • the present invention firstly relates to a portable lamp of the kind comprising a socket housed in a handle comprising a relatively rigid sheath in a relatively flexible outer casing and a protective basket with a closed collar fitted on the handle , characterized in that an annular groove formed in the external wall of the envelope is fitted into the collar of smaller diameter prior to locking by force fitting the frustoconical sheath into the flexible envelope of complementary conicity, thus ensuring and the rigidity of the handle and the non-removable attachment of the flexible envelope and the protective basket, while the sleeve is removably mounted on a front support surface provided for this purpose at the end of said sheath.
  • the inner sheath of the protective handle When, then, the inner sheath of the protective handle is placed in the outer casing of the latter, it advantageously locks the assembly, sufficiently energetically to oppose any subsequent disassembly of the protective basket.
  • the basket mounting operation takes place concurrently with that leading to the assembly between them of the two component parts of the grip handle.
  • the assembly of the assembly is therefore particularly economical.
  • a portable lamp generally comprises a hollow grip handle 10, a socket 11 housed in said handle 10 and suitable for positioning a lamp (not shown), and a protective basket 12 attached to the grip handle 10.
  • the grip handle 10 is of composite structure, said grip handle comprising, engaged one inside the other, an internal sheath 13, made of relatively rigid material, and a outer casing 14, made of relatively flexible material, and on the other hand, the protective basket 12 comprises, at its base, for its securing to the handle, a fixing collar 15 closed on itself continuously, by which it is engaged on said grip handle 10.
  • the grip handle 10 which extends downwards from the fixing collar 15 of the protective basket 12, is generally frustoconical, its section decreasing in moving away from said fixing collar 15.
  • the protective basket 12 extends upwards, around the sleeve 11, beyond the fixing collar 15 of this protective basket 12.
  • the extension 17 which thus presents upwards, at its end, the grip handle 10 essentially belongs to its only outer casing 14 and it forms a truncated cone whose section goes in decreasing away from the fixing collar 15 of the protective basket 12.
  • the casing 14 of the grip handle 10 has externally, for this fixing collar 15, an annular groove 18, formed, in a manner known per se, between two transverse shoulders 19, 20 .
  • the outer casing 14 of the handle 10 has internally, in the embodiment shown, vertical grooves 26 , which, alternating with ribs 27, make it possible to lighten the material necessary for the constitution of such an external envelope 14, and to facilitate the positioning and blocking of the various parts in question.
  • the outer casing 14 of the grip handle 10 is pierced with an opening 29, for passage of the cable suitable for serving the socket 11, and forms a nozzle 31 suitable for clamping on such a cable.
  • the internal sheath 13 of the grip handle 10 has a generally truncated configuration complementary to that of the lower part of the associated external casing 14, for simple axial engagement by force therein.
  • this internal sheath 13 is within the skill of the art, and therefore will not be described in detail here.
  • this internal sheath 13 has, projecting inwards, a hollow pillar 32, forming, on its upper surface, for support of the socket. 11 and fixing of the latter, a sole 33 -on which opens, parallel to the axis of the assembly, a bore 34.
  • the internal sheath 13 also has internally, projecting at its upper part, ribs 35, some of which extend downwards.
  • the base 36 At its base, the base 36 has a heel 38, by which it bears on the sole 33 of the pillar 32 of the internal sheath 13, and which is perforated, for placement of a fixing screw.
  • the base 36 projects a collar 40, by which it carries axially on the ribs 35 of the internal sleeve 13.
  • the socket 11 is in one piece with the plate 24 which is integral therewith, and the latter, in addition to the switch 23, carries the various connection elements necessary for the connection and maintenance of the cable serving this socket 11 (not fully detailed in the figures).
  • the protective basket 12 is entirely produced in a homogeneous manner using wires of circular cross section suitably assembled two by two by welding.
  • these are steel wires, preferably provided with a protective and insulating coating on the surface.
  • the fixing collar 15 of the protective basket 12 is thus formed of two round wires 42, each of which is continuously closed on itself and which are established at a distance from each other, parallel to each other, at a spacing less than the corresponding axial height of the groove 18 of the outer casing 14 of the grip handle 10.
  • the rings which constitute these round wires 42 have a circular contour, homothetic to that of the grip handle 10, but it goes without saying that this is not necessarily so.
  • this outline could be for example hexagonal or square, or, more generally polygonal, the grip handle 10 then having itself in section a corresponding outline.
  • the overall diameter of the rings that constitute the round wires 42 is chosen so as to be slightly less than that of the bottom of the groove 18 of the grip handle 10, for an energetic tightening thereof.
  • a second step one then axially engages, through the protective basket 12, and along arrow F2 of FIG. 4, the internal sheath 13 of the protective handle 10 in the external envelope 14 thereof.
  • FIG. 5 illustrates, also by way of example, another type of portable lamp to which the invention can be applied.
  • It is a waterproof portable lamp comprising, in the protective basket 12, around the lamp concerned (not shown), a glass 45, which is removably attached to the grip handle 10, at the end of it. ci, and which must be removable, for access to the lamp, without the protective basket 12 being itself removed.
  • the grip handle 10 extends upwards, beyond the fixing collar 15 of the protective basket 12, and the extension 17 which it thus presents upwards belongs for the essential to its external envelope 14; this in fact departs from the inner sheath 13 from the fixing collar 15 of the protective basket 12 and first flares upward, following the profile of said protective basket 12; then, it forms, at its end, a truncated cone 46 the section of which, complementary to the base of the verrine 45 for nesting thereof, decreases as it moves away from the fixing collar 15 of the protective basket 12 .
  • the outer casing 14 is placed in the protective basket 12 through the upper opening thereof, according to arrow F3 in FIG. 5, and the inner sheath 13 is then put in place. place, along the same arrow F3, in said outer envelope 14.
  • the fixing collar of the protective basket is formed of two rings of wires closed on themselves continuously, which gives it a good foundation, it is not necessarily so .
  • it can consist of only one of such rings.
  • the internal sheath of the grip handle can for example be made of synthetic material, called plastic, chosen for its rigidity, and, the associated external envelope be made of rubber material chosen for its flexibility.
