SPRAYING DEVICE OF AEROSOL CONTAINED IN A REMOVABLE TANK The present invention relates to a device designed for the spraying of aerosol from a removable tank fixed on an assembly plate, whereby the action of the movement of a door or of another movable means, operates the valve of the aerosol tank by means of a member which moves first in one direction, then by the action of a spring moves in the opposite direction.

There are known devices accomplishing the same objective, by means of which an operating contact of the valve of the aerosol tank is brought into service either by a mechanical device or by an electrical means, in order to spray a certain quantity of a deodorant, disinfectant, insecticide or other analogous products in aerosol form into the interior of a room, especially in a bath room or rest room, when the door of the room is brought into movement. Such devices are, however,

undesirable in certain respects. They have the disadvantage of being relatively expensive and they require a skilled workman for installation and service.

The object of the present invention is to eliminate such disadvantages by means of a control member operating an actuating member retained in its inoperative position by means of springs and able to rotate or oscillate around a shaft fixed on a small supporting plate joined rigidly to the assembly plate of the device. The control member actuates the valve of the aerosol tank when it moves in one direction but has no effect on the valve when it moves in the opposite direction or when it is in an intermediate inoperative position.

A preferred embodiment of the invention is shown in the attached drawing wherein the single FIGURE is a side elevation of the device.

Referring to the drawing in detail, the invention includes a mounting plate 1 designed to be screwed onto a door, a door frame or a wall. The mounting plate 1 is joined rigidly with an angle iron 2 having a horizontally bent flange at its lower end which serves as a support for an adjusting screw 3 disposed parallel to the plane of the plate 1. The screw 3 is provided with a supporting head 4 indicated by dotted lines in the draw- The head engages the bottom of an aerosol tank 6 which is frictionally gripped by a jaw 5 secured to the plate I so as to permit vertical adjustment of said tank to proper operating position. I

The tank 6 and the jaw 5 are covered having a removable cover 7 with a spraying opening 7a illustrated in a dot-dash lines in the drawing. The device is, also provided at the top of the mounting plate, with a plunger or button Sengaged by a helical spring 9. The push-button 8 is fixed on one end of a slidable spindle 11 which passes through a guide sleeve 10 screwed into mounting plate 1. The other end of the spindle 11 is provided with a head 12.

When the push-button 8 is moved, for example by the shutting of a door, the spring 9 is compressed and the spindle 11 is moved to a position 11', sliding in the guide sleeve l0 screwed in the mounting plate 1. The head 12 strikes the edge of a cam 15, retained in its inoperative position by means of a helical spring 14. The cam 15 is made preferably of a plastic material which is easily slidable and wear resistant, for example of polyfluorethylene. This cam is able to rotate on a fixed shaft on a small supporting-plate or arm 13 joined rigidly to the mounting plate 1.

During its rotating movement, the cam 15 depresses a leaf spring 16 also joined rigidly to the mounting plate 1, the said leaf spring 16 in turn depressing the valve 17 of the aerosol tank 6, which causes the spraying of a certain quantity of aerosol. When the door remains shut and when the push-head 12 has attained the position 12' as shown in the drawing in dot-dash lines, the cam 15 returns to its inoperative or rest position under action of the springs l4, l6 and of the spring (not shown) which normally urges the valve 17 to a closed position.

During the next opening of the door, the pushbutton 8 and cylindrical spring 9 are not actuated thereby because the spindle 11 has been returned to its inoperative position as illustrated by full lines in the drawing by expansion of spring 9 acting on push-button 8. During the return of spindle 11, the head 12 moves over the cam 15 without having any effect on the valve 17 of the aerosol tank 6, so that the process as described above can be repeated when the door is shut again.

I claim:

1.- A spraying device comprising in combination a mounting plate, means on said mounting plate for removably and adjustably supporting an aerosol container, said container including a depressible valve member at one end thereof, a plunger slidably mounted on said plate and including an inner end and an outer end, spring means normally urging said plunger into inoperative position, a rotatable cam member mounted on said plate beneath said plunger and above the depressible valve member of said aerosol container, a portion of said cam member normally disposed in the path of said plunger, a leaf spring mounted on said plate between said cam member and said depressible valve member whereby upon the exertion of axial force upon the outer end of said plunger causing slidable movement thereof, the inner end of said plunger strikes a portion of said cam member to rotate it into engagement with said leaf spring, forcing said spring downwardly against said depressible valve member.

2. A spraying device according to claim 1 wherein the means for removably and adjustably supporting said aerosol container includes a jaw member gripping the side wall of said container and an adjusting screw including a head which engages the bottom wall of said container to permit adjustment of the position of said container relative to said leaf spring and cam member.

3. A spraying device according to claim 1 wherein said cam member is mounted on a shaft at one end of an arm, the other end of said arm secured to said mounting plate and a helical spring is connected to said arm and cam to retain said cam in inoperative position.

Claims (3)

1. A spraying device comprising in combination a mounting plate, means on said mounting plate for removably and adjustably supporting an aerosol container, said container including a depressible valve member at one end thereof, a plunger slidably mounted on said plate and including an inner end and an outer end, spring means normally urging said plunger into inoperative position, a rotatable cam member mounted on said plate beneath said plunger and above the depressible valve member of said aerosol container, a portion of said cam member normally disposed in the path of said plunger, a leaf spring mounted on said plate between said cam member and said depressible valve member whereby upon the exertion of axial force upon the outer end of said plunger causing slidable movement thereof, the inner end of said plunger strikes a portion of said cam member to rotate it into engagement with said leaf spring, forcing said spring downwardly against said depressible valve member.

2. A spraying device according to claim 1 wherein the means for removably and adjustably supporting said aerosol container includes a jaw member gripping the side wall of said container and an adjusting screw including a head which engages the bottom wall of said container to permit adjustment of the position of said container relative to said leaf spring and cam member.

3. A spraying device according to claim 1 wherein said cam member is mounted on a shaft at one end of an arm, the other end of said arm secured to said mounting plate and a helical spring is connected to said arm and cam to retain said cam in inoperative position.
