Combination garden tiller and sprinkler head grass trimmer

Abstract

Apparatus for trimming grass around sprinkler heads or tending a small garden area includes a tubular member having a plurality of serrations formed on one end for cutting grass around such sprinkler heads. A housing member partially disposed for reciprocal movement within the tubular member. A plate disposed for closing one end of housing member and having an outer periphery engageable with an inner surface of such tubular member for guiding during reciprocal movement. A second guide disposed around outer periphery of such housing member intermediate each end thereof. Another elongated rod like member engages an end of such first elongated rod like member. A caged biasing means is disposed over the second rod like member for absorbing shock during use of apparatus and a mechanism for manipulating the apparatus while trimming such grass around such sprinkler head or tending such small garden area.

Claims

1. An apparatus for trimming grass from around a head portion of a lawn water sprinkler, said apparatus comprising: (a) an elongated generally hollow tubular member closed at a first end thereof, said elongated tubular member having each of a predetermined length and a predetermined diameter;(b) a plurality of serrations at least one of formed on and attached to a second axially opposed end of said elongated generally hollow tubular member for cutting grass disposed around such head portion of such lawn water sprinkler; and(c) a means engageable with said first closed end of said elongated generally hollow tubular member for manipulating said apparatus for trimming such grass from around such head portion of such lawn sprinkler.

2. An apparatus, according to claim 1, wherein said means engageable with said first closed end of said elongated generally hollow tubular member for manipulating said apparatus for trimming such grass from around such head portion of such lawn sprinkler is one of power driven and manually operated.

3. An apparatus, according to claim 2, wherein said means engageable with said first closed end of said elongated generally hollow tubular member for manipulating said apparatus for trimming such grass from around such head portion of such lawn sprinkler is manually operated by a handle.

4. An apparatus, according to claim 2, wherein said means engageable with said first closed end of said elongated generally hollow tubular member for manipulating said apparatus for trimming such grass from around such head portion of such lawn sprinkler is power driven by a motor.

5. An apparatus, according to claim 1, wherein said second axially opposed end of said elongated generally hollow tubular member is heat treated for hardening.

6. An apparatus for at least one of tilling, weeding and cultivating a small garden area, said apparatus comprising: (a) a first elongated rod like member having each of a predetermined length and a first predetermined cross-sectional shape in a direction transverse to said predetermined length;(b) a predetermined number of tine members secured to an outer surface of said elongated rod like member adjacent a first end thereof for penetrating a ground surface to said at least one of tilling, weeding and cultivating a small garden area;(c) a second elongated rod like member engageable at a first end thereof with a second axially opposed end of said first elongated rod like member;(d) a biasing means disposed over said second elongated rod like member and caged between a pair of plate like members for absorbing shock during use of said apparatus; and(e) a means engageable with a second end of said second elongated rod like member for manipulating said apparatus during said at least one of tilling, weeding and cultivating a small garden area.

7. An apparatus, according to claim 6, wherein said first predetermined cross-sectional shape of said first elongated rod like member is one of generally round, hexagonal and octagonal.

8. An apparatus, according to claim 7, wherein said first predetermined cross-sectional shape of said first elongated rod like member is generally round.

9. An apparatus, according to claim 6, wherein said biasing means is a spring.

10. An apparatus, according to claim 9, wherein said spring is a coil compression spring.

11. An apparatus, according to claim 6, wherein said predetermined number of tine members is six.

12. An apparatus, according to claim 11, wherein said tine members include a sharpen point.

13. An apparatus, according to claim 6, wherein said means engageable with a second end of said second elongated rod like member for manipulating said apparatus during said at least one of tilling, weeding and cultivating a small garden area is one of power driven and manually operated.

14. An apparatus for at least one of trimming grass from around a head portion of a lawn water sprinkler and at least one of tilling, weeding and cultivating a small garden area, said apparatus comprising: (a) an elongated generally hollow tubular member closed at a first end thereof, said elongated tubular member having each of a predetermined length and a predetermined diameter;(b) a plurality of serrations formed on a second axially opposed end of said elongated generally hollow tubular member for cutting grass disposed around such head portion of such lawn water sprinkler;(c) an elongated generally hollow housing member at least partially disposed for reciprocal movement within said elongated generally hollow tubular member, said elongated generally hollow housing member being open at a first end thereof and having each of a predetermined length and a predetermined cross-sectional shape in a direction transverse to said predetermined length;(d) a plate like means disposed at a second end of said axially opposed second end of said elongated generally hollow housing member for closing said second end of said elongated generally hollow housing member and having an outer periphery thereof engageable with an inner surface of said elongated generally hollow tubular member for providing a first portion of a guide means during said reciprocal movement;(e) a second portion of said guide means disposed around an outer periphery of said elongated generally hollow housing member intermediate each end thereof and having an outer periphery engageable with said inner surface of said elongated generally hollow tubular member for providing a first portion of said guide means during said reciprocal movement;(f) a first elongated rod like member having each of a predetermined length and a first predetermined cross-sectional shape in a direction transverse to said predetermined length;(g) a predetermined number of tine members secured to an outer surface of said first elongated rod like member adjacent a first end thereof for penetrating a ground surface to said at least one of till, weed and cultivate a small garden area;(h) a second elongated rod like member engageable at a first end thereof with a second axially opposed end of said first elongated rod like member;(i) a biasing means disposed over said second elongated rod like member and caged between a pair of plate like members for absorbing shock during use of said apparatus;(j) a means engageable with one of said first closed end of said elongated generally hollow tubular member and said second end of said second elongated rod like member for manipulating said apparatus for at least one of trimming such grass from around such head portion of such lawn sprinkler and at least one of tilling, weeding and cultivating a small garden area.
