Abstract
A straight line impact absorbing striking tool for impacting an object. The striking tool may have a multi-piece construction, and may be partially filled with a flowable high-density material and/or may include a spring-loaded handle to help absorb impact recoil energy that would otherwise be undesirably transferred to the hand(s) and arm(s) of a user. At least a striking section or striking surface of such a tool may be comprised of a material that will not mar or otherwise damage an impacted target object.
Claims20
A straight line impact absorbing striking tool comprising:
- a body portion having a leading striking surface for impacting a target object;
- a plugged cavity within said body portion, said cavity containing an amount of a flowable high-density material;
- a handle having a first end retained within a bore in said body portion and a second end extending rearward through an aperture in said body portion and substantially along the longitudinal axis thereof;
- and
- at least one spring located between said first end of said handle and a bottom wall of said bore;
- wherein, upon propelling said striking tool into a target object along a path substantially parallel to said longitudinal axis thereof, movement of said flowable high-density material within said cavity and compression of said spring by said handle act to absorb impact recoil forces.

A straight line impact absorbing striking tool comprising:
- a body portion having an impacting section with a leading striking surface for impacting a target object, and a removable rear cap;
- a plugged cavity within said impacting section, said cavity containing an amount of a flowable high-density material;
- a handle having a first end retained within a bore in said rear cap and a second end extending rearward through an aperture in said rear cap and along the longitudinal axis of said body portion;
- and
- at least one spring located within said bore in said rear cap, between said first end of said handle and said plugged cavity in said impacting section;
- wherein, upon propelling said striking tool into a target object along a path substantially parallel to said longitudinal axis thereof, movement of said flowable high-density material within said cavity and compression of said at least one spring by said handle act to absorb impact recoil forces.
3 more elements
A straight line impact absorbing striking tool comprising:
- a body portion having a forward impacting section with a leading striking surface for impacting a target object, and a removable rear cap threaded into a like-threaded counterbore at a rear of said impacting section;
- a cavity within said impacting section, said cavity containing an amount of a flowable high-density material;
- a plug threaded into said counterbore in said impacting section for sealing said cavity, said plug including a number of longitudinally oriented threaded holes;
- a number of guide rods threaded at one end thereof into said threaded holes in said plug, said guide rods extending rearward toward said rear cap;
- a handle having a flanged end retained within a bore in said rear cap and an opposite end extending rearward through an aperture in said rear cap and along the longitudinal axis of the body portion;
- a number of guide bores extending from said flanged end of said handle toward said opposite end, said guide bores of appropriate size and arrangement to receive said guide rods so as to provide for guided reciprocating movement of said handle;
- and
- at least one spring located within said bore in said rear cap, between said flanged end of said handle and said threaded plug;
- wherein, upon propelling said striking tool into a target object along a path substantially parallel to said longitudinal axis thereof, movement of said flowable high-density material within said cavity and compression of said at least one spring by said handle act to absorb impact recoil forces.
