May 5, 1970 BATISTELLI EXTENSION TOOL FOR AEROSOL DISPENSERS Filed March 10, 1969 INVENTOR. Mm o BAT/5 au BY/ZJZ/M United States Patent U.S. Cl. 222-174 8 Claims ABSTRACT OF THE DISCLOSURE A portable combined support and control for a pressurized container of the aerosol type in which the support forms a handle and carries an actuator for the valve of the container so arranged that gripping the handle and actuator will release the valve. Means are provided to quickly and readily attach an extension pole handle with means on the pole handle for also controlling the valve actuator.
This is a continuation-in-part of my copending patent application Ser. No. 699,122, filed Ian. 19, 1968.
This invention relates to supports for supporting pressurized containers of the aerosol type for cleaning walls, etc., and for applying paint, insecticides, etc., to remote locations.
Pressurized containers of the aerosol type are commonly used for applying sprays of various kinds and extension pole handles have been used heretofore for extending the reach of such containers and for remotely controlling the same. Such eXtension handles work satis factorily. However, it is often desirable to dispense with such a pole handle in the event the area to be sprayed is within ones reach. At other times it may be desirable to use pole handles of different lengths so as to reach areas not normally accessible. Prior pole handles of which I am aware do not lend themselves to quick and easy removal or replacement of pole handles or extensions of different lengths. Also, such prior handles utilize cords for operating valve release devices and such cords are partly or wholly outside the pole handle which not only renders the assembly unsightly but the cord tends to catch on projections and cause unwanted release of the valve.
Therefore, a principal object of the present invention is to provide a pole handle extension device of the foregoing type which may be quickly and easily removed or replaced by other pole handles or different lengths.
Another object is to provide a pole handle extension of the above type in which the controls are mainly contained within the pole handle.
Another object is to provide a pole handle of the above type with means for quickly and rapidly adjusting the controls for pole handles of different lengths.
Another object is to provide a pole handle extension device of the above type which is economical to manufacture and easy to assemble and disassemble.
The manner in which the above and other objects of the invention are accomplished will be readily understood on reference to the following specification when read in conjunction with the accompanying drawings, wherein:
FIG. 1 is a side view of an aerosol container holder and pole handle embodying a preferred form of the present invention.
FIG. 2 is a front view of the holder.
FIG. 3 is a sectional plan view taken substantially along the line 3-3 of FIG. 7.
FIG. 4 is a sectional plan view of the actuator arm lock and is taken along line 4-4 of FIG. 1.
FIG. 5 is a sectional plan view taken along line 5-5 of FIG. 1.
3,510,028 Patented May 5, 1970 "ice FIG. 6 is a transverse sectional view of the adjustable (gilgl'lng and is taken substantially along line 66 of FIG. 7 is an enlarged longitudinal sectional view, with parts broken away, of the pole handle.
FIG. 8 is a detail view of part of the control chain.
The holder or support, generally indicated at 11, is preferably formed of plastic and has an opening at its forward side (as viewed in FIG. 2) which closely conforms to the outer contour of a pressurized aerosol container 12 of conventional form so that the container can be readily slipped into place in a properly oriented position only. The holder is formed into three substantially semicircular arms 13, 14 and 15 which frictionally grip the sides of the container to retain the same in place and yet permit ready removal thereof. A rearwardly extending U-shape handle 16 is formed integral at its lower end with the arm 15 and at its upper end with an arch element 17 which, in turn, is formed integral with the upper semicircular arm .13. The arch element 17 extends downward on opposite sides to form a guard.
An actuating arm 18 is pivoted on the handle 16 at 19 and comprises a forward extension 20 which overlies the valve member 21 of the aerosol container. A downward extension 22 of the actuating arm extends directly in front of a part of the handle 16 so that when the handle is grasped and the extension 22 squeezed thereagainst, the arm will be rocked slightly counterclockwise to actuate the valve member 21 to release fluid from the container in the form of a spray from an orifice 23 formed in the valve member.
A safety" lock is provided to block the arm 18 against operation. Such device comprises a button 24 slideably mounted in a bearing 25 formed in the handle 16. The button is provided with an enlarged head 26 normally located out of the path of the arm 18. However, when the head 26 of the button is pressed inward, it will locate in blocking relation with the arm 18 to block it against movement. It will be noted that the arm is beveled at 27, permitting the button to cam the arm fully into its inoperative position in the event it is not already in such position when the button is pressed inward.
The support 11 is adapted to be quickly mounted at the upper end of a pole handle generally indicated at 30 and to be quickly removed therefrom. For this purpose, socket members 31 and 32 are formed integral with the support 11 to receive the pole handle. A tongue 29 extending inwardly from the socket member 31engages in a slot 33 formed in a tubular pole 34 forming part of the pole handle to properly orient the tube and prevent relative rotation between the same and the support.
A plug member 35, preferably of plastic, is fitted within the pole 34 at its upper end and is provided with a tongue 36 fitted within a corresponding slot in the pole 34.
A second plug 37, also preferably of plastic, is fitted within the lower end of the pole 34 and has a slot 38 therein to receive a control arm 40 (see also FIG. 3). A pin 41 extends through the arm 40 and the plug to pivotally support the arm. A tongue 42 on the plug 37 is fitted in a slot in the pole 34 to prevent relative turning. The arm 40 extends through a slot 43 in an extension tube 44 which is frictionally fitted over pole 34 and is held in place by a slightly tapered plastic retainer bushing 45 fitted over the upper end of the tubing 44.
A chain device generally indicated at 46 is provided to control the actuating arm 18 from the control arm 40. Such chain is preferably formed of plastic and comprises an upper section 47 slideable endwise in a counter opening 48 in the plug 33. A flange 51 integral with the section 47 has a plurality of thin flexible fingers 60 depend- 3 ng therefrom and engaging a bottom shoulder 57 formed n the plugs. The plug is preferably formed in two halves which are suitably cemented together. A T-shaped head 50 extends upwardly from chain section 47 and the chain :lement 51 (see also FIG. 8) extends downwardly therefrom. The latter contains a series of spaced balls 52 in- .egral with the chain for attachment to the control handle #0. For this purpose, the lower end of the chain is guided :hrough a cross-slot 53 in the plug 37 and extends through a slot 54 in the side of the arm 40. A lower ball 52 is 'eceived in a cavity 55 in the handle, forming a connec- ;ion with the chain. Normally, the chain is held in its lpper position shown in FIG. 7, by the spring fingers 60.
A coupling device is provided for quickly connecting he T-member 50 of the chain to the actuating arm 18. inch coupling device comprises an eccentric 58 formed f two inwardly flanged eccentric members 160 (see also FIG. 6) rotatably mounted in a bearing 61 formed in the trm 18 and suitably secured together, as by adhesive. Kligned slots 62 are formed in the eccentric members so hat when the eccentric is rotated to vertically position he slots, they may readily receive the T-member 50. thereafter, upon rotation of the eccentric, flanges 63 hereon will engage the cross-head 59 of the T-member take up any clearance therebetween and thus adjust or any change in length of the chain member. Accordngly, upon gripping both the pole handle and the control trm 40, the chain 51 will be pulled downward against he action of spring fingers 60 to actuate the arm 18 to lause the valve 21 to release the fluid from the container. Thus, the fingers 60 will buckle, but will straighten when DI'CSSHI'B on control arm 40 is released.
Pole handles of different lengths may be used or the ole 34 may be shortened as desired while using the same :hain device. In this case, a diflerent ball 52 would be itted within the cavity 55 and any extra length of chain nay be allowed to extend downwardly in the extension 44.
A post 158 is formed integral with the support 11 for tttachment of suitable tools, such as a sponge (not hown).
