Abstract

A quick-releasing pivoting support for a line trimmer, which includes the use of a detachable interconnection such as a ball-and-socket to at least partially support the weight of a line trimmer while still allowing pivoting of the trimmer. In the case of an emergency, the trimmer may be simply lifted upwardly while still keeping both hands on the trimmer and quickly discarded by the operator.

Claims

1. A support apparatus for a vegetation trimmer having a shaft and a rotating cutting head adjacent one end of said shaft, said support apparatus comprising:

a holster configured for support by the human body;

a detachable collar for attachment around said shaft of said trimmer, said detachable collar configured to support at least a portion of said weight of said trimmer;

interconnection means comprising a ball and socket, wherein one of said collar and said holster is substantially rigidly attached relative to said ball so as to be substantially stationary therewith, and the other of said collar and said holster is substantially rigidly attached relative to said socket so as to be substantially stationary wherewith, such that said trimmer may be attached relative to said holster in a ball and socket interconnection allowing said trimmer to be at least partially pivoted relative to said holster, and such that said trimmer may be lifted generally upwardly to disengage said ball and socket connection to disengage said trimmer from said holster.

2. The apparatus as claimed in claim 1, wherein said ball is attached relative to said trimmer and said socket is attached relative said holster.

3. The apparatus as claimed in claim 1, wherein said socket is attached relative to said trimmer and said ball is attached relative said holster.

4. The apparatus as claimed in claim 1, further comprising a belt for attaching said holster relative to said human body.

5. The apparatus as claimed in claim 1, further comprising a shoulder strap for attaching said holster relative to said human body.

6. A trimmer support assembly for at least partially supporting the weight of a vegetation trimmer having a shaft and a cutting head proximate one end of said shaft while being held by an operator, comprising:

a holster member;

means for attaching said holster member to the body of said operator; and

quick-releasing pivoting interconnection means including a protruding member having a tip and a recessed member configured to accept said tip while allowing relative pivoting therebetween, one of said protruding and recessed members being substantially rigidly attached relative to said holster so as to be substantially stationary therewith, and the other of said protruding and recessed members being substantially rigidly attached relative to said trimmer so as to be substantially stationary therewith,

such that at least part of the weight of said trimmer is transferred through said interconnection means to said holster and further to said operator while said trimmer is still allowed to pivot relative to said holster, and such that said trimmer may be detached relative to said holster by lifting it upwardly.

7. The assembly as claimed in claim 6, wherein the pivot point between said protruding and recessed members is below said longitudinal axis of said shaft of said trimmer.

8. A trimmer support assembly for transferring at least part of the weight of a vegetation trimmer to an operator while said trimmer is being held by an operator, comprising:

a holster member configured to be supported by said operator;

a protruding member having a tip; and

a recessed member configured to accept said tip while allowing relative pivoting therebetween, one of said protruding and recessed members being substantially rigidly attached relative to said holster so as to be substantially stationary therewith, and the other of said protruding and recessed members being substantially rigidly attached relative to said trimmer so as to be substantially stationary therewith,

such that at least part of the weight of said trimmer is transferred through said interconnection means to said holster and further to said operator while said trimmer is still allowed to pivot relative to said holster, and such that said trimmer may be detached relative to said holster by lifting it upwardly.

9. A hand-held apparatus for trimming grass or other vegetation, comprising:

a trimmer having a shaft;

a holster configured for support by the human body;

a detachable collar for substantially rigid attachment around said shaft of said trimmer, said detachable collar configured to support at least a portion of said weight of said trimmer; and

interconnection means comprising a ball and socket, wherein one of said collar and said holster is substantially rigidly attached to said ball, and the other of said collar and said holster is substantially rigidly attached to said socket, such that said trimmer may be pivotably attached relative to said holster in a ball and socket interconnection allowing said trimmer to be at least partially pivoted relative to said holster, and such that said trimmer may be lifted generally upwardly to disengage said ball and socket connection to disengage said trimmer from said holster.

10. A support apparatus for a vegetation trimmer having a shaft, said apparatus comprising:

a holster configured for support by the human body;

a detachable collar for attachment around said shaft of said trimmer, said detachable collar configured to support at least a portion of said weight of said trimmer;

interconnection means comprising a ball and socket, wherein said socket is attached relative to said trimmer so as to be substantially stationary therewith, and said ball is attached relative said holster so as to be substantially stationary therewith, such that said trimmer may be attached relative to said holster in a ball and socket interconnection allowing said trimmer to be at least partially pivoted relative to said holster, and such that said trimmer may be lifted generally upwardly to disengage said ball and socket connection to disengage said trimmer from said holster.

11. The application as claimed in claim 10, further comprising a belt for attaching said holster relative to said human body.

12. The application as claimed in claim 10, further comprising a shoulder strap for attaching said holster relative to said human body.

13. A trimmer support assembly for at least partially supporting the weight of a vegetation trimmer while being held by an operator, said trimmer having a shaft and a rotatable vegetation cutting head, comprising:

a holster member;

means for attaching said holster member to the body of said operator; and

quick-releasing pivoting interconnection means including a protruding member having a tip and a recessed member configured to accept said tip while allowing relative pivoting therebetween, one of said protruding and recessed members being attached relative to said holster, and the other of said protruding and recessed members being attached relative to said trimmer, wherein the pivot point between said protruding and recessed members is below said longitudinal axis of said shaft of said trimmer.

such that at least part of the weight of said trimmer is transferred through said interconnection means to said holster while said trimmer is still allowed to pivot relative to said holster to facilitate cutting by said cutting head, and such that said trimmer may be detached relative to said holster by lifting it upwardly.
