Definitions

  • the present invention relates to a portable device capable of being used for the application of a product, liquid or pasty, contained in a reservoir containing a delivery piston.
  • the delivery piston can be subjected either to the action of a pressure spring, or to a pneumatic pressure generated by a pump provided in the device.
  • the first solution has the disadvantage that the product to be expelled is constantly subjected to a discharge pressure, so that it tends to flow continuously out of the device.
  • it is necessary to be able to interrupt at will the flow of the product to be applied.
  • the present invention aims to achieve an apparatus of the type mentioned above, but which is designed so that one can have a sufficiently high discharge pressure and that, moreover, the operation of this device is extremely easy.
  • the pneumatic pump provided in the apparatus consists of a roller pump operating continuously when the apparatus is used and the outlet conduit of which is subdivided into two branches, namely a first branch connected to the bottom of the tank containing the product to be expelled, and a second branch opening freely to the atmosphere. Furthermore, a shutter member is provided on this second branch so that the air discharged by the pump can be directed at will into the bottom of the tank at will in order to control the expulsion of the product to be applied. It therefore suffices to act on the shutter thus provided to control or interrupt the output of this product.
  • this shutter is constituted, or actuated, by a push button or the like capable of ensuring, moreover, the closing of the motor control circuit driving the roller pump, the arrangement of this push button being such that in a first partial insertion position, it ensures that this motor is put into operation, while in a second complete insertion position, it controls the closing of the second branch of the outlet conduit of the roller pump, while keeping the drive motor in operation.
  • the device shown in Figures 1 to 3 is a portable device intended to be used for the application of shoe polish, or other pasty maintenance product, on shoes or leather articles as well as for the subsequent polishing of the product thus applied.
  • This device is of the type described in French patent 75 00265 of the Applicant, because it comprises a coating pad 1 and a buffing brush 2, both driven in rotation by a motor 3 and which can be one or the other brought into the projecting working position by reversing the direction of rotation of this motor.
  • This device comprises a casing 4 containing all of the members thereof.
  • This casing has an opening 5 outside which can protrude either the coating pad 1, or the annular buffing brush 2 disposed around it, a cap 6 ensuring the closing of the casing when the device is not not used.
  • the annular brush 2 is carried by a sleeve 7 rotatably mounted inside a fixed bush 8, integral with the casing.
  • this sleeve is arranged around the cylindrical body of a central reservoir containing the product to be expelled, and which is itself rotatably mounted inside the casing.
  • the sleeve 7 is also capable of sliding in the axial direction and that it is connected to the reservoir 9 by a quick-pitch thread consisting of a thread 10 on the internal wall of this sleeve, and a projecting thread correspondent on the tank 9.
  • the arrangement thus provided allows that by rotating the reservoir 9 in a determined direction, this causes the displacement of the sleeve 7 and of the brush 2 forwards, so that the latter comes in projecting position relative to the coating pad 1.
  • the reversal of the direction of rotation of the reservoir 9 has the effect to control the backward movement of the brush 2 in the withdrawal position.
  • the central reservoir 9 consists of a cartridge removably mounted inside the casing 4, and which can be easily removed therefrom with the sleeve 7 and the brush 2 carried by the latter.
  • the cartridge At its opposite end to the coating buffer 1, the cartridge is closed by a head 11 carrying a collar 12 intended to be engaged in 'inside a fixed sleeve 13, forming a bearing, which is fixed to the housing.
  • this head 11 carries an external skirt 14 capable of being fitted around a drive bush 15, carried by a toothed ring 16, the rotationally joining of the skirt 14 and the bush 15 being ensured by flats complementary provided on these two bodies.
  • the crown 16 is driven by the motor 3, the output shaft 17 of which carries a pinion 18 meshing therewith.
  • an expulsion pusher 19 is provided arranged in an opening made in the corresponding part of the casing 4 and which is thus accessible from the outside.
  • This pusher carries push rods 20 capable of acting on the collar 12 of the head 11 when a thrust is exerted on it, so as to mosaice the cartridge 9 outside the device, a spring 21 then ensuring the return of the pusher to its rest position.
  • the removable cartridge 9 contains a piston 22 intended to ensure the delivery of the pasty product to be expelled, in this case shoe polish 23, placed in the front part of this cartridge and which is capable of coming out by an adjustment 24 to impregnate the pad with coating 1.
  • a fixed nozzle 25 on which can be fitted the collar 12 of the head 11 thereof. This adjustment is connected to an air delivery pump thereby enabling pneumatic pressure to be exerted on the piston 22 in order to expel the product to be applied.
  • the pneumatic pump provided therein consists of a roller pump, permanently driven by the same motor as the coating pad and the buffing brush and this, permanently during the use of the device .
  • This pump is constituted by a flexible tube 26 arranged in an arc of a circle around three rollers 27 carried by the ring gear 16.
  • a rigid retaining wall 28 is arranged around the tube 26 in its part in an arc of a circle, so that each rollers 27 can cause localized crushing of this tube, as shown in FIG. 3.
  • the fixed fitting 25 On the first outlet thereof, is connected the fixed fitting 25, which opens into the bottom of the cartridge 9 when the latter is in place inside the device.
  • the second outlet 32 of the connector it carries a tube 33 opening freely to the atmosphere.
  • a shutter member is disposed opposite this tube to close the exhaust to the atmosphere at will.
  • the shutter member of the second outlet branch 33 of the pump consists of a pusher 34 distinct from the engine control member of the device.
  • the shutter of the second outlet branch of the pump is constituted by a push button 35 which is also arranged to control the start-up as well as the reversal of rotation of the motor 3 of the device.
  • this push button extends transversely inside the corresponding part of the casing and its ends 35a and 35b protrude outside through openings provided in the corresponding walls thereof.
  • This push button carries a finger 36 disposed opposite the outlet branch 33 of the air delivery pump and which is capable of crushing the flexible tube constituting this branch, so as to close it. To this end, it suffices to push the push button completely in the direction of the arrow Fa by exerting a push on its end 35a.
  • the pusher 35 is moreover coupled with a rotary disc 37 carrying electrical contacts for starting and reversing the direction of rotation of the motor 3.
  • this disc 37 carries a projecting arm 38 which is engaged in a transverse notch 39 of the pusher 35.
  • the movement of the latter is capable of rotating the disc 37 in one direction or the other.
  • the roller pump has no effect on the delivery piston.
  • a spring 40a ensures the return of the pusher 35 to its first position as soon as the user slightly releases the pressure on the pusher 35, a complete relaxation determining the return of this pusher to its normal rest position.
  • this pusher When this pusher is actuated in the opposite direction, that is to say in the direction of the arrow Fb, by pushing on its end 35b, it turns the disc 37 in the opposite direction.
  • the coating pad 1 also continues to rotate on itself. But it is then neutralized since it is set back relative to the buffing brush 2.
  • roller pump which also continues to rotate, is completely neutralized due to the reversal of the direction of rotation of the crown 16.
  • the present device has the advantage that the operation of a single member makes it possible to control the operation of the engine in one direction and in the other as well as the sending of pressurized air to the piston of repression. As a result, this device is very easy to maneuver.
  • Figure 4 shows another embodiment of the device according to the invention. It is then a much simpler device, having no rotary working element, unlike what is the case in the device described above.
  • the device illustrated in Figure 4 is simply intended to allow the application under pressure, of a liquid or pasty product 23a of any kind.
  • This product is contained inside a reservoir 9a formed by the casing 4a of the device and which also contains a delivery piston 22a.
  • the output of the product to be expelled is effected by an adjustment 24a capable of being closed by a plug or cap and through which the filling of the reservoir 9a can also be carried out.
  • this tank opens a nozzle 25a connected to the first branch of the outlet pipe of a roller pump, such as that shown in FIG. 3.
  • the second branch of the outlet pipe of this pump opens freely, but can be closed by the operation of a pusher 34a, accessible outside the device.
  • this device is extremely easy to maneuver. Now this device can be used to apply many products of a very different nature, for example a sealant or similar, glue, etc.
