Abstract
Mounting apparatus 10 for use with commercial electric hedge trimming apparatus 12 comprises a hand-held support frame 14 to support the hedge trimmer at one end 18. The hedge trimmer is angularly adjustable in direction A about an axis 19 to vary the angle of cut. Mounting means 20 for the hedge trimmer provides both for said angular adjustment of the trimmer and for releasably securing it to the apparatus whereby the hand tool 22 may be detached for subsequent direct hand operation by a user.
Claims7
Mounting apparatus (10) for use with hedge and the like cutting apparatus (12), said mounting apparatus comprising:
- support arm means (14) adapted to be carried by a user to support drivable cutting means (16) at one end (18) thereof;
- said cutting means (16) being angularly adjustable (A) with respect to said support arm means (14);
- mounting means (20) at said one end (18) of said support arm means to receive and support an electrically or otherwise powered hand tool (22) providing said cutting means (16);
- said mounting means (20) providing said angular adjustment (A) of said cutting means with respect to said support arm means (14) to vary the angle of cut;
- releasable securing means (24) for releasably securing said hand tool (22) to said mounting means (20) whereby said hand tool may be detached for subsequent direct hand operation by a user;
- said support arm means further comprising frame means having a pair of widely spaced frame side members extending lengthwise of the frame, one frame side member at each side thereof, and at least one frame cross-member connected between and linking said side members in a spaced apart relationship;
- said frame means having said mounting means at its outer end to receive and support said hand tool and having in the region of its inner end a pair of spaced apart connectors for detachable connection to a user's body harness, one of said connectors being located in the region of each side of the frame at said inner end thereof, and said frame side members being spaced apart by a distance substantially greater than the width of said mounting means for said hand tool whereby said frame side members can be conveniently grasped between the inner and outer ends of said frame means by the user during use, and said frame means can thus be held in an upward inclination while the weight of the apparatus and tool is substantially supported by said harness;
- the spacial relationship of said frame with respect to said mounting means being such that said mounting means can receive and mount said cutting means so that the cutting means can cut in a lateral direction which is generally the same direction as the direction in which said frame side members are spaced apart, whereby said spaced apart frame members grasped by the user permit effective control of cutter movement in said lateral cutting direction, and
- control means for controlling the operation of said hand tool being mounted on said frame within finger reach of one of said user's hands when grasping said frame side members.

- said cutting means (16) being angularly adjustable (A) with respect to said support arm means (14);
- mounting means (20) at said one end (18) of said support arm means to receive and support an electrically or otherwise powered hand tool (22) providing said cutting means (16);
- said mounting means (20) providing said angular adjustment (A) of said cutting means with respect to said support arm means (14) to vary the angle of cut;
- releasable securing means (24) for releasably securing said hand tool (22) to said mounting means (20) whereby said hand tool may be detached for subsequent direct hand operation by a user;
- on/off switch means (38) mounted on said support arm means to control said hand tool (22) said switch means being biased to its off condition and having a switch actuator element (44) positioned for finger control by a user holding said support arm means (14), and
- said switch means (38) including lock means to lock said switch actuator (44) in its off condition, said lock means being releasable by a release element (46) separate from said switch actuator element (44) whereby actuation of said switch (38) to its on condition by said switch actuator element (44) requires also simultaneous actuation of said release element (46).
