  1 The invention relates to a method and to a device allowing to bring in a clean and fast way the empty or wired electrical sheaths (16), in particular in the dry cell partitions (12) and \ or the thermal insulating linings and acoustic, up to reservations

  (17) provided for electrical equipment without damaging them and without making any holes

  intermediaries requiring a filling. Being able to embed said sheaths (16) without having to make holes and plug them

  undoubtedly corresponds to the expectations of each installer.

  The characteristics and advantages of the invention will appear more clearly on reading

  the following detailed description, in the development of a tested and proven prototype given as

  non-limiting example and shown in the accompanying drawings.

  - Figure I shows a front view of the lower part of the invention.

  - Figure 2 shows a front view of the upper part of the invention - Figure 3 shows a side view of the lower part of the invention and a sectional view of said partitions - Figure 4 shows a view of the side of the invention and a sectional view of said partitions - Figure 5 shows a global front view of the invention Figure 6 shows a side view of the invention - Figure 7 shows a side view of a part of the invention 1 The method according to the invention consists of: 1 - placing the tool on said partition (12) between the arrival of said sheath and said reservation (17) provided for the apparatus 2 - A hold said tool on said partition (12) by means of two upper (13) and lower (8) jigs of the pole (15/1) which is enclosed in the lower thickness of said partition (12). The invention, that is to say said tool being held by the force of an integrated tensioner (not shown) in the upper part of said telescopic pole (15/1) composed of two or

  three extenders, or more or less.

  3 - Said telescopic pole is composed of two parts:

  - a fixed part (1) fitted with a clamping screw (14) allowing the desired distance to be adjusted -

  and the force of a tensioner which is incorporated in the second part of said pole (1) which is composed of two sliding tubes (15) 4 Said telescopic pole can also be provided with said tensioner fixed to the upper part of said

  pole (15/1) directly at the lower part thereof, thus eliminating the clamping screw.

  5 - Said telescopic pole (15-1) may be provided with either a single cylinder gauge (4) accompanied by its three rotary pulleys (2,3,7) and its guide (5) in the case of said

  dry cell partitions (12) or others.

  Either of the double cylinder template (22.19) equipped with its guide (23) and of the curved template (18) accompanied by the needle (6) for the case of said thermal linings but this is not limiting since said double template cylinder (22,19) can be used in all cases

  of figure (dubbing or partitions) and at the convenience of each user.

  6 - Once said tool is fixed, said needle (6) made of fiberglass (one of another semi-rigid material) equipped or not with said curved template (18) is sent from said simple cylinder template (4) or of said double cylinder template (22.19) adapted to the reservation of the apparatus (17) For the case of said dry cell partitions (12) or others ("PLACOSTYL", "BA13" etc ---) said guide (5) as well as two said rotary cylinders (7,3) make it possible to accompany said needle (6) in its trajectory and this so that said needle (6) arrives precisely opposite said template

  top (13) of said pole (15,1) for attachment of said sheath (16).

  For the case of said thermal (or phonic) doublings, said guide (23) as well as said curved template (18) provided with its four rotary pulleys (20) allow said needle (6) to slide through this said curved template (18) thus making it possible to accompany the needle (6) in its trajectory and this so that said needle (6) arrives precisely opposite said high gauge (13)

  of said pole (15,1) for the attachment of said sheath (16).

  1 7 - The tip (10) of said needle (6) is equipped with a sharp point (10/11) allowing for

  the case of dry cell partitions, piercing the cells without difficulty.

  8 - Said pierced metal tip (10/11) of said needle (6) can be replaced by a thermal end piece (electrical resistance) for passing said sheaths (16) through the thermal insulating linings which are used in the building, such as polystyrene, polyurethane, etc ... Said heating tip will have a different shape to be able to advance without

  be stopped by any roughness (cement, glue, holes ...).

  Said tip will be supplied with direct or alternating current and a voltage in accordance with standards

of security.

  For the case of said doublings, said needle (6) is first sent into said curved template (18) making it possible to give said needle (6) the necessary curvature so that it can be held flat along the plate. plaster glued to said lining when it penetrates therein, avoiding

  thus any risk of roughness external to this said dubbing.

  9 - Once said needle (6), equipped with its said heating nozzle, sent into said curved template (18) The assembly is sent via said double cylinder template (22,19) and said guide (23) for the making a passage inside said insulating lining such as the

  polystyrene, polyurethane or others.

  - For thermal and acoustic insulating linings such as glass wool or rock wool, the said heating end piece is replaced by said sharp end piece (10,11) allowing easy passage of these but that while retaining said curved template (18) and said double cylinder jig (22,19) integral with its said guide (23) allowing a precise setting and guiding of said bent jig (18) for the sending of said needle (6) 11 - Said jig curved (18) is stopped by a cleat (21) when sent with said needle (6) of said double cylinder template (22,19) and this so that on the one hand said needle (6) can slide to the inside this said curved template (18) and take the desired curvature and on the other hand so that said needle (6) can penetrate said lining to said top template (13) without difficulty. Said stopper (21) in abutment between said double cylinder template (22,19) and said guide (23) gives said curved template (18) the exact trajectory for sending said needle (6) through said doubling and \ or said drywall or other 12 - Said heating nozzle will be electrically powered in the case of a resistance, but the installer will also have the possibility of heating said nozzle with the flame of a torch

  if this proves preferable for him (absence of current on site for example).

  Said heating tip will have a bevel shape which will help said needle (6) to press against

the plaster wall.

  Its 25 mm section will allow the passage of said most used sheaths (20-25 mm) while

  minimizing damage to the insulation.

  The wires feeding said heated tip will be incorporated into said fiberglass needle (6)

  or another material giving it the same characteristics.

  1 13 - The said end piece (10) is provided with a hole (11) in which a cable loop has passed

  thus allowing the attachment of said sheaths (16) (with or without wires) or a cable.

  14 - By means of a cable (9) which advantageously replaces said loop, it is hooked to said perforated tip (11) of said needle (6), said needle (6) is sent with said cable (9) to the top of said pole (15) and the high template (13). Detach said cable (9) from said tip (10) of said needle (6), remove said needle (6)

  and hooking said sheath (16) to said cable (9).

  - Said sheath (16) being hooked, we just have to remove said cable (9) to be able

  return said sheath (16) to said reservation (17).

  We can therefore remove said tool simply by pulling said tensioner incorporated in said telescopic pole (15/1) and lifting said tool up or down, depending on the position of the device seen that the use of it this can be done in all positions (vertical, horizontal, diagonal ...) 16 - An important characteristic according to the invention is that said loop can be replaced by said cable (9) brought by said needle and its pierced end (6 / 10/11) We unhook said cable (9) to hang said sheath (16) we remove said needle (6) and without coming down from its stepladder (for example for a sheath arriving at height) we can thus bring back said sheath 16) by pulling on said cable (9) passing through an intermediate pulley (2) which will allow

  channel the effort and bring back said sheath (16) without moving from its stepladder.

  This allows said sheath (16) to be pushed with one arm while the other arm pulls said cable (9) to

  bring back said sheath (16) without having to bend down or descend from the stepladder.

  17 - In the case of said insulating linings, said electrical sheath (16) or the cables can be sent directly after the passage of said needle (6) and its said heating endpiece and this

  without the means of said cable (9) or said loop if desired.

  18 - The said tool and the parts which compose it can be manufactured by materials such as steel, ABS resinous, or any other plastics. In fact the choice is not limiting and

  also depends on the technical possibilities during its manufacture.

  19 - Device not shown (according to paragraph 16), characterized in that said cable (9) can

  be pulled by means of a reel provided with a handle fixed on the top of said pole (15) to wind said cable (9) around said reel and thus multiply the effort produced to pull said sheath (16) - Said high and low templates (13 and 8) can be adapted without limitation to the upper or lower thickness of said partitions (12). We can easily think of a setting

  sliding of these so-called templates. (13 and 8).
