EXTENSION TOOLS 3 Sheets-Sheet 3 Filed Oct. 23, 1964 INVENTORS JAMES A. WAiTE FREDERICK M. CONROY ATTORNEYS United States Patent 3,229,859 EXTENSION TOOLS Frederick M. Conroy, 11320 William St., and James A. Waite, 11078 William St., both of Taylor, Mich. Filed Oct. 23, 1964, Ser. No. 406,961 17 Claims. (Cl. 222-174) The present application is a continuation-in-part to our co-pending application Ser. No. 249,850, filed January 7, 1963 now abandoned.

The present application relates to an extension handle for a large variety of tools and the like and more particularly to such a handle especially suitable for holding pressure actuated cannisters and having means for actuating a spray valve of such a cannister to dispense the contents thereof.

It is often desired to reach high places with various devices such as mops, squeegees, or the like. Heretofore, there has not been an extension handle for reaching such areas which is adapted to receive and hold a large variety of devices of diiierent shapes and sizes. One form of the present invention provides such an extension handle having a uniquely formed mounting means at each end thereof which will receive the handles of many different types of tools or other similar devices such as mops, paint rollers, squeegees, pruning saws, and the like.

Further, a large number of liquid products are presently being packaged in pressure actuated spray cans which dispense the liquid in spray form through an orifice controlled by a plunger or a button actuated valve. It is often desirable to use such cannisters in places beyond the reach of the user, for instance when cleaning windows or other high areas. The mounting means provided on the extension tools of the present invention are adapted to receive such pressure actuated cannisters and means are provided for actuating the spray valve of such a cannister. Although a number of difierent types of handles have been heretofore disclosed for use with such cannisters, many of these had as the principal object the facilitation of the manipulation of the valve actuating plunger. Handles ofthis nature have been disclosed in United States Patents Nos. 2,820,578; 2,877,934 and 2,803,383.

Each of the handles disclosed in the aforementioned patents are provided with means which clamp to the neck bead usually provided on such cannisters. As thehe cannisters are presently being manufactured, such neck beads are provided but if this structure is eliminated in the future, other clamping means will have to be devised for such holders. Further, such holders have the disadvantage that a small clamping area at the-top of the can nister is depended upon for support, and also that the holder must be tailored to a particular size cannister, and the sizes of course vary. Further, these handles cannot be used for tools or devices other than cylindrical cannisters or the like.

Other types of handles have heretofore been disclosed in United States Patents Nos. 3,017,056 and 3,069,095 issued to C. J. Bishop on January 16, 1962 and December 18, 1962, respectively. While these patents disclose extension handles for pressurized spray cans having mounting means thereon for clamping to the lateral surface of the can, the mounting means therein disclosed are in the form of a circular clamp member. Such a mounting means necessarily limits the size of cannisters which can ice be accommodated by the extension handles therein disclosed. Further, no means are disclosed in these patents for receiving other tools and devices of various sizes and shapes.

It is an object then of the present invention to facilitate the use of tools or other devices such as "mops, squeegees, and the like by providing an extension handle for such devices having means for clamping the handle to such devices and being adapted to receive such devices having a large variety of sizes and shapes.

It is another object of the present invention to facilitate the use of pressure actuated cannisters by providing an extension handle having means for clamping the handle to cannisters of various sizes and means for actuating the valve of the cannister.

It is another object of the present invention to improve detachable holders for pressure actuated cannisters by providing means for clamping said holders to a variety of difierent size cannisters.

It is still another object of the present invention to facilitate the clamping of tools and devices of a large variety of sizes and shapes to an extension handle by providing clamping means for such a handle comprising a substantially V-shaped mounting block and means for clamping the tool or device against the diverging leg portions of the mounting block.

Still further objects and advantages of the present invention will readily occur to one skilled in the art to which the invention pertains upon reference to the following drawings and in which like reference characters refer to like parts throughout the several views and in which FIG. 1 is an elevational view illustrating a preferred embodiment of the present invention in use; I,

Now referring to the drawings for a more detailed description of the present invention, FIGS. 1-6 illustrate a preferred handle device being used to carry a pressure actuated cylindrical spray cannister 12. It is to be understood that although it has been preferred to illustrate the handle device of the present invention as being used for such a cannister 12 it will be apparent as the description proceeds that the handle device of FIGS. 1-6 can be used to carry many other types of toolsand devices suchas mops, squeegees, brushes, paint rollers, and the like. The preferred handle device of FIGS. 1-6 comprises a support member which, as can best be seen in FIG. 2, is preferably substantially V-shaped in lateral cross-section and is provided with diverging leg portions 11 defining a support surface 13 and which are adapted to engage portions of the lateral surface of the pressure actuated cylindrical spray cannister 12. The particular construction of the support member 10 permits the handle device to be used to carry spray cannisters of many different diameters as well as other various tools of many difierent sizes and shapes.

The support member 10 is preferably provided with a medial recess 15 which receives a flexible clamp member 16. The clamp member 16 is adapted to encompass a portion of the lateral surface of the spray cannister 12. Flanged end portions 17 carry a bolt 18 and a winged nut 19 for tightening the clamp member 16 and thereby clamping the spray cannister against the support surface 13 formed by the leg portions 11 of the support member 10. If desired the clamp member 16 could be secured to or be integral with the support member 10. It is apparent then that various sizes and shapes of tools and devices can be secured to the handle of the present invention by using the clamp member 16 to clamp the tools or devices against the leg portions 11 of the support member 10. The particular V-shape of the support member 10 insures that tools of various sizes and shapes will be securely clamped against the support member 10 upon tightening the clamp member 16.

A tubular member 20 extends laterally from the support member 10 and is provided at its free end with a plurality of annularly spaced longitudinally extending slots 21. A tubular member 22 preferably of a smaller diameter than the tubular member 20 is carried by the tubular member 20. A clamp 23 is provided to radially compress the slotted end portion of the tubular member 20. and thereby secure the

tubular members

20 and 22 one to the other.

A third tubular member 24 preferably telescopic-ally receives the tubular member 22 so that the length of the handle device maybe varied. The end of the tubular member 24 adjacent the tubular member 22 is preferably provided with. a plurality of longitudinally extending annularly spaced slots 25. A clamp 26 is provided so that the slotted end portion of a tubular member 24 may be radially compressed about the tubular member 22 to secure the handle device at a desired length.

As can best be seen in FIG. 2, a longitudinal slot 30 is provided in the tubular member 20 in a position such that its longitudinal axis is substantially coplanar with the longitudinal axis of the support member 10 and the spray cannister 12 carried thereby. The slot 30 is preferably provided with an enlarged circular end portion 31.

A lever 32 is pivotally carried in the slot 30 by pivot pin 33 and nut 34. As can best be seen in FIG. 2 the sides of the tubular member 20 formed by the slot 30 engage the lever 32 so that lateral movement of the lever 32 is prevented. The enlarged portion 31 permits the lever 32 to be readily inserted in the slot 30 during assembly.

The lever 32 is preferably bent as at 33A and 34A to form a straight end portion 35 adapted to engage the spray valve button 36' of the spray eannister 12. It is apparent that pivoting the lever 32 will cause the straight end portion 35 of the lever 32 to depress the'button 32 to emit a spray from the cannister 12.

The free end of the lever 32 is preferably provided with an eyelet 40 to which is secured a string or wire 41. A guide 42 for the string or wire may be provided as shown on the tubular member 24. The tubular member 24 may also be provided with an actuating mechanism 43 to which the free end of the string or Wire 41 may be releasably attached. The actuating mechanism 43 preferably comprises a member 44 pivotally carried by the tubular member 24 as at 45 and a spring 46 urging the member 44 to pivot away from the tubular member 24. A stop 47 limits the outward pivotal movement of the member 44 i and a perforation 48 is provided to receive the string or wire 41.

It is apparent that pivoting of the member 44 against the force of the spring 46 will cause the lever 32 to pivot the end portion 35 downwardly to depress the button 36 to actuate the cannister 12. If ,it is desired to change the length of the handle the Wire or string may be loosened from the member 44 and retied when the handle has been adjusted to the desired length.

It is also apparent that if a device other than the spray cannister 12 is to be clamped to the support member 10 either the straight portion 35 of the lever 32 will be pivoted away from the support member 10 or the handle device will be turned upside down so that the tool or device can extend upwardly from the lower portion of the sup-. 1

port member 10.

FIG. 7 illustrates a preferred modification of the present invention substantially. similar to the device described above except that an accessory mounting means 50 has been provided extending laterally from the tubular member 40. It is to be understood that the mounting means 50 could also be positioned to extend outwardly from the exterior surface of the support member 10 if so desired. The means 50 is preferably tapered as shown and is adapted to receive a squeegee, brush, or other accessories of those types having a hollow handle portion-and which may be desirable for use at the same time the support member 10 is being used to carry a spray cannister 12.

FIGS. 811 illustrate another preferred embodiment ofv the present invention quite similar to those described above and comprising a substantially V-shaped support member having diverging leg portions 111. The free ends o the leg portions 111 are formed outwardly as at 113 to. provide. the means for receiving a U-sh-aped clamping member 116. The clamp member 116 is adapted to encompass a portion of the lateral surface of a spray cannister 12 or other tool 'or device and the free ends of the 123 preferably secures the tubular member 122 to the tubular member 120 and support member 110. t

A third tubular member 124. is received by the tubular 1 member 122 and as can best be seen in FIG. 11 the tubular member 124 carries a pair of radially outwardly extending pins 125. The tubular member 122 is provided with slots 126 which as can best be seen in FIG. 8 extend axially from the free end of the tubular member 122 and then extend annularly so that upon insertion of the tubular member 124 intothe tubular member 122 with the pins positioned in the slots 126, relative twisting of the tubular members 122 and 124-will lock the

tubular members

122 and 124 one to the other as illustrated.

As can best beseen in FIG. 9, a longitudinal slot 130 is provided in the tubular member 120 in a position such that its longitudinal axis is substantially co-planar with the longitudinal axis of the support member 110 and the spray cannister 12 carried thereby. A lever 132 is pivotally carried in the 'slot 130 by a pivot pin 1'33 and a nut 134. The lever 132 is preferably bent as at 133A to form a; straight end portion 135 adapted to engage the spray valve button 36 of the spray cannister 12. It is apparent that pivoting of the lever 132 will cause the straight end por-' tion 135 of the lever 132 to depress the button 36 to emit a spray from the cannister 12.

The free end of the lever 132 is preferably provided with an eyelet 140, as can best be seen in FIG. 8 to which is secured a string or wire 141. An actuating member 144 is pivotally carried as at 145 by the tubular member 124 and is provided with an eyelet 147 which receives the free end of the string or wire 141. Pivoting the member 144 will cause the lever 132 to pivot to bring the end portion 35 downwardly against the spray button 36 to actuate the cannister 12.

The'free end of the tubular member 124 is preferably provided with a second support member 150. As can best be seen in FIG. the support member 150 is preferably secured to the end of the tubular member 124 by a screw 152. The support member 150 preferably comprises a' pairof axially spaced substantially V-shaped outwardly extending arm portions 154. A substantially U-shaped clamping member 156 is disposed intermediate the arm portions 154 and has its threaded free ends extending through suitable perforations provided in the support member 159 so that upon tightening the wing nuts 160 the clamp 156 is urged radially inwardly toward the arm portions 154 to securely clamp any suitable tool or accessory such as the squeegee 162 shown in dashed lines in FIG. 9 to the end of the tubular member 124.

It is apparent that the present invention provides a handle means which has been constructed to accommodate many difl'erent tools and accessories of various sizes and shapes and which will accommodate all the different size pressure actuated cannisters now being manufactured. The V-shaped support members illustrated-will carry cannisters of many different size diameters as well as other tools, accessories, and devices of various sizes and shapes. It is apparent that the particular construction disclosed has particular usefulness for supporting pressure actuated cannisters and does not depend upon such cannisters being provided with a neck bead. In the embodiments illustrated in FIGS. 7 and 8-11 means are provided for mounting various tools and devices to the handle while such handel is being used to carry the spray cannister 12 so that a device such as a mop, brush, squeege or the like which may be useful in conjunction with the liquid being dispensedby the spray cannister 12 can be secured to the handle device.

It is also apparent that although we have described but several embodiments of the present invention'many other changes and modifications ca be made without departing from the spirit of the invention as expressed by the appended claims.
