Description

The present invention generally relates to

  the portable lamps, that is to say the electric lamps which, arranged at the end of a thread of appropriate length, can be moved by hand by their user, at the option of the latter.

  It aims more particularly those of these

  which, in addition to a piece of

  hollow grip and a socket housed in said handle for the installation of an electric lamp, a

  protection basket attached to this handle

  if we. Most often, that the handle is unitarily made of relatively rigid material, or,

  composite structure, it includes an inner sheath

  dull in relatively rigid material and an ex-

  in relatively flexible terms, the protective basket

  tion is usually made to date in welded metal and

  includes, a fastening collar, formed of a strap or-

  green to be closed by one or more screws on the handle, and a wire superstructure carried by the

said collar.

  Although such an achievement has given and

  give further satisfaction, it submits, with regard to

  rings the protective basket, disadvantages, which are

The following.

  Because it comprises both son, for the realization of its superstructure, and a strip, for that of its collar, the manufacture of such a protective basket is relatively delicate, the welding to implement requiring different settings depending on whether to assemble wires between them or that it is to assemble such son to strap, and it is therefore

relatively expensive.

  In addition, the mounting of such a protective basket on the handle to be equipped not only involves placing this protective basket on this handle, but also the tightening of one or more screws

  necessary to close its fastening collar.

  This assembly is therefore relatively long, delicate and oné

reux -

  Finally, by unscrewing the screws in question, the protective basket can be removed from the handle, to the detriment of safety.

  It has certainly been proposed in the French patent

  on 19 January 1978 under the number 78 0244 '4 and published under the

  No 2 415 158, a portable lamp in which the basket of

  tection, entirely made of yarn, including its fastening collar, which is then closed on itself continuously,

  is simply engaged axially on the handle

  to equip, without the implementation of any

Clamping.

  But in the French patent in question, such a pa-

  protection is applied to the realization of a

  deuse with indémontable socket of particular type.

  Such a wander, which involves a mode of execution

  specific for the socket and handle, would not be appropriate

to all use cases.

  The present invention generally has the

  object the extension to other types of

  fastening with fastening collar closed on itself continuously

  protection basket, and therefore, if desired, a

  homogeneous whole of such a basket of protec-

tion.

  More specifically, the present invention firstly relates to a portable device of the type comprising a hollow grip handle, a sleeve housed in said handle, and a protective basket attached thereto, this portable device being characterized in that that, in combination, on the one hand the handle is of composite structure, said handle comprising, engaged one in the other, a sheath

  relatively rigid material and an outer envelope

  relatively flexible, and on the other hand the

  protective basket has at its base, for its subjection

  on the handle, a fastening collar closed

  even continuously by which it is engaged on said handle.

  The present invention also relates to the process

  specific to the assembly of the various constituents of such a bala-

  Deuse. According to the invention, this method is characterized in that it first assures the relative mounting of the protective basket and the outer casing of the handle pre-

  heightened, and in that then one engages, through the pa-

  deny protection, the inner sleeve of the handle of

  gripping in the outer shell of it.

  Thus, to ensure the desired assembly, it is advan-

  Taken advantageously according to the invention of the structure

  flexible outer shell of the handle.

  It is indeed thanks to the flexibility of this one that can be assured without difficulty the relative assembly of this

  outer casing and protective basket.

  When, then, the inner sleeve of the protective handle is put in place in the outer casing of

  this one, it locks advantageously all, suffi-

  vigorously to oppose further disassembly

  Thus, according to the invention, the assembly operation of the basket is inserted between that leading to the assembly of the two parts constituting the gripping handle.

  Advantageously, these various operations do not

  that simple axial commitments of the various parts of

these in question.

  The assembly of the whole is therefore particularly eco-

  nomic. In short, the assembly by simple axial engagement of the component parts of the portable lamp according to the invention, combined with the implementation thereof for a protective basket that can be made entirely homogeneously son suitably welded, leads, the others

  conditions being equal, an advance reduction

  25 to 30%, the cost of manufacturing

  this portable lamp vis-à-vis the common type of portable

  parable. The characteristics and advantages of the invention

  will emerge from the following description,

  for example, with reference to the accompanying schematic drawings in which: Figure 1 is an elevational view of a portable lamp according to the invention;

  Figure 2 is a larger scale, a view par-

  axial section, with local tearing; Figures 3 and 4 show, on a different scale,

  Figure 2, and illustrate the way of mounting the bala-

  deuse according to the invention; FIG. 5 is, on a different scale, a similar view

  to that of Figure 4 and relates to another portable lamp

the invention.

  As illustrated in these figures, and in a known manner in

  self, a portable lamp according to the invention comprises in a manner

  generally, a hollow grip handle 10, a sleeve

  11 housed in said handle 10 and suitable for the implementation

  place of a lamp (not shown), and a protective basket

  12 attached to the handle 10.

  According to the invention, and in combination, on the one hand the handle 10 is of composite structure, said handle comprising, engaged one inside the other, an inner sleeve 13, relatively rigid material, and a outer casing 14, relatively flexible material, and secondly, the protective basket 12 comprises at its base, for its subjection to the handle, a fastening collar 15 closed on itself continuously, by which it is

  engaged on said handle 10.

  In the embodiment shown, in FIGS.

  1 to 4, the handle 10, which extends towards the

  low from the fixing collar 15 of the protective basket

  tion 12, is generally frustoconical, its section going

  descending away from said clamp 15.

  Preferably in this embodiment, and as shown, in the protective basket 12, it extends upwards, around the sleeve 11, beyond the

  clamp 15 of this protective basket 12.

  According to one aspect of the invention, the extension 17

  that thus presents upward, at its end, the po-

  gripping force 10 belongs essentially to its

  the outer casing 14 and it forms a truncated cone whose section decreases away from the clamp 15 of the protective basket 12. In practice, in the embodiment shown,

  the casing 14 of the gripping handle 10 has ex-

  subsequently, for this clamping collar 15, an annular groove 18, formed, in a manner known per se, between two

transverse shoulders 19, 20.

  In addition, it comprises, in the embodiment shown, which concerns for example a portable switch with built-in switch, and in a manner known per se, below this groove 18, a section of thinned thickness

  21, disposed in line with an opening 22 of the inner sheath

  13, to allow easy action on a switch

  23 carried by a plate 24 integral with the sleeve 11.

  But it goes without saying that such a switch is not im-

  this is the most general case.

  At the right of the collar 15 of the protective basket 12, and in practice, on either side thereof, the outer casing 1 '4 of the handle 10 has, internally, in the embodiment shown, grooves vertical members 26, which, alternating with ribs 27, make it possible to lighten the material necessary for the constitution of such an outer envelope 14, and to facilitate the setting up and blocking

various parts involved.

  At its base, the outer casing 14 of the handle

  10 is pierced with an opening 29, for passage of the own cable to the serving of the sleeve 11, and forms a

  tip 31 clean to tighten on such a cable.

  The inner sleeve 13 of the handle 10 generally has a frustoconical configuration complementary to that of the lower part of the outer casing 14

  associated, for simple axial engagement force in it.

  The constitution of this inner sleeve 13 falls within

  those skilled in the art, and it will therefore not be described in detail.

tail here.

  It will be sufficient to specify that, in a position diametrically opposed to the opening 22 mentioned above, this inner sleeve 15 has, projecting inwards, a hollow pillar 32 forming, on its upper surface, for support of the socket 11 and fixing thereof, a sole 33 on which emerges, parallel to the axis of the assembly, a

piercing 34.

  For support of the sleeve 11, the inner sleeve 13 further includes, internally, projecting at its upper part, ribs 35, some of which extend

down.

  The constitution of the sleeve It is also the responsibility of

  art, and well known in itself, it will not be

described in detail here>.

  It will suffice to say that, in the form of

  As shown, it comprises on the one hand a base 36, carrying the necessary connection elements, and on the other hand a skirt 37 which, projecting upwards on the base 36, extends to the end. Corresponding

  the outer casing 14 of the handle 10.

  At its base, the base 36 has a heel 38,

  which it bears on the sole 33 of the pillar 32 of the inner sheath 13, and which is perforated, for setting up a

fixing screw 39.

  In addition, externally, the base 36 projects a flange 40, by which it bears axially on the

ribs 35 of the inner sheath 13.

  In practice, the sleeve 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

  this sleeve (not fully detailed in the figures). In the embodiment shown, the protective basket 12 is made entirely homogeneously to

  using circular cross-section wires suitable for

  two by two welded together.

  In practice, this is steel wire, preferably

  provided on the surface with a protective and insulating coating.

  In the embodiment shown, the fastening collar 15 of the protective basket 12 is thus formed of two round wires 42, each of which is closed on itself continuously and which are located at a distance from one another, in parallel to each other, at a distance less than

  the corresponding axial height of the groove 18 of the enve-

  external loppe 14 of the handle 10.

  In the exemplary embodiment shown, the rings constituted by these round wires 42 have a circular contour, homothetic to that of the handle 10, but

  it goes without saying that it is not necessarily so.

  On the contrary, this outline could be for example

  hexagonal or square, or in a more general polygo-

  nal, the grip handle 10 having itself in itself

section a corresponding outline.

  The overall diameter of the rings constituted by the

  round wire 42 is chosen so as to be slightly less

  to the bottom of the groove 18 of the handle

  tension 10, for an energetic tightening thereof.

  For mounting the portable lamp thus formed, it is firstly ensured, firstly, the relative mounting of the protective basket 12 and the outer casing 14 of the

grip handle 10.

  This assembly is made by axial engagement of said enve-

  outer loppe 14 in the protective basket 12, along the arrow Fl of Figure 3, and, as it is easy to the

  understanding, this commitment, which is allowed by the flexible-

  relative of this external envelope 14, it is de-

  forming accordingly, is facilitated by the taper of

  extension 17 that furthermore presents this envelope exter-

  14, said extension 17 forming the end of engagement

  of said outer casing 14.

  In a second step, it then engages axially, through the protective basket 12, and following the arrow F 2 of Figure 4, the inner sleeve 13 of the handle of

  protection 10 in the outer casing 14 thereof.

This commitment is made by force.

  At the end, the protective basket 12 is

  locked on the handle 10.

  It is then sufficient to place the sleeve 11 in the handle 10, and to attach it by a screw 39. Figure 5 illustrates, also by way of example, a

  another type of portable lamp to which the invention

  tion. It is a waterproof light guide comprising, in the protective basket 12, around the lamp concerned (not shown), a verrine 45, which is reported in a manner

  removable on the handle 10, at the end of this

  ci, and which must be removable, for access to the lamp,

  without the protective basket 12 is itself deposited.

  In such a case, and as before, the handle 10 extends upwards, beyond the clamp 15 of the protective basket 12, and the extension

  17 that it thus presents upwards belongs to the

  felt at its outer envelope 14; it deviates in

  effect of the inner sleeve 13 from the fixing collar

  15 of the protective basket 12 and goes first to evacuate

  upward, following the profile of the said basket of

  section 12; then, it forms, at its end, a truncated cone 46 whose section, complementary to the base of the verrine 45 for nesting thereof, is decreasing

  away from the fastening collar 15 of the carrier basket

12.

  In such an embodiment, the outer envelope

  14 is placed in the protective basket 12 by the upper opening thereof, along the arrow F 3 of Figure 5, and the inner sleeve 13 is then placed in the same arrow F 3, in said envelope

external 14.

  Of course, the present invention is not limited to the embodiments described and shown, but

  encompasses any variant of execution.

  In particular, if in the embodiments

  shown, the fixing collar of the protective basket is formed of two rings in son closed on themselves continuously, which gives it a good seat, it is not

not necessarily so.

  For example, it may consist of only one such rings. Alternatively, it may be formed of a closed strip on itself although, for the reasons explained above,

  a son embodiment is preferred.

  In all cases, the inner sleeve of the gripping handle may for example be made of synthetic material, called plastic, chosen for its rigidity, and, the outer casing associated be of rubbery material

chosen for its flexibility.
