Abstract
A dead blow hammer has a skeleton including a cylindrical head tube and a cylindrical neck tube fixed to the head tube and projecting laterally therefrom and receiving therein a disk-like plastic spacer and the working end of an elongated plastic handle core, which is adhesively secured in the neck tube. The head tube contains shot and the ends thereof are closed by end caps having cylindrical, longitudinally-slotted flanges press-fitted in the ends of the head tube. The entire skeleton is encapsulated in an overmolded plastic sheath which includes an inner covering and a flexible and resilient grip further overmolded on the inner covering adjacent to the distal end of the handle member.
Claims26
A hammer comprising:
- an elongated head having a longitudinal axis,
- a neck tube integral with the head and projecting therefrom and inclined with respect to the longitudinal axis,
- a handle including a member having a proximal working end received in the neck tube and a distal end, and
- a spacer disposed in the neck tube between the head and the handle member working end.
A hammer comprising
- an elongated cylindrical head tube having a longitudinal axis and an open end,
- a handle fixed to the head tube and projecting therefrom and inclined with respect to the longitudinal axis, and
- an end cap having a generally cylindrical flange press fitted inside the open end of the head tube for closure thereof,
- the flange includes a plurality of circumferentially spaced, axially extending beads projecting radially outwardly from an outer surface thereof.
A hammer comprising:
- an elongated cylindrical head tube having a longitudinal axis and an open end,
- a neck tube integral with the head tube and projecting therefrom and inclined with respect to the longitudinal axis,
- a handle including a member having a proximal working end received in the neck tube and a distal end,
- a spacer disposed in the neck tube between the head tube and the handle member working end, and
- an end cap having a generally cylindrical flange press fitted in the open end of the head tube for closure thereof.
A method of making a hammer comprising:
- providing a hollow tubular head and a neck tube integral with the head and extending therefrom,
- inserting a working end of a handle core member in the neck tube so that it is spaced from the head, and
- encapsulating the head and the neck tube and the core member in a plastic covering.
