Abstract

A hammer tacker includes an outer housing comprising a handle portion and a head portion, the outer housing formed from a fiber reinforced polymer material. The hammer tacker also includes an elongated staple holder carried at least partially within the outer housing, the elongated staple holder being slideable between a use position and a refill position. The outer housing having the fiber reinforced polymer material defines a channel extending through the handle portion and into the head portion, the channel configured to receive the staple holder. The staple holder is slidable along the channel of the outer housing between the use position and the refill position. The hammer tacker further includes a staple driver assembly operable to drive a staple from the staple holder into a workpiece.

First claim

What is claimed:

1. A hammer tacker, comprising:
a die-formed outer housing comprising a handle portion, a head portion, and a channel extending through the handle portion and into the head portion,
wherein the outer housing is formed from a fiber reinforced polymer material;
an elongated staple holder carried at least partially within the outer housing, the elongated staple holder including a pusher being slidable along the channel between a use position and a refill position;
the outer housing comprising ribs formed from the fiber reinforced polymer material, a portion of the channel is configured to receive the staple holder,
wherein the portion of the channel comprises an inverted U-shaped portion,
wherein the inverted U-shaped portion of the channel is formed from the fiber reinforced polymer material and comprises a top portion and two side portions,
wherein at least some of the ribs extend from both the top portion and at least one of the side portions of the inverted U-shaped portion; and
a staple driver assembly operable to drive a staple from the staple holder into a workpiece.

2. The hammer tacker according to claim 1 , wherein the staple holder is slidable alongside a plurality of ribs formed on opposite side surfaces of the channel.

3. The hammer tacker according to claim 1 , wherein the staple holder is configured to carry a plurality of staples thereon, and wherein an interior surface of the channel is directly exposed to staples.

4. The hammer tacker according to claim 3 , wherein the plurality of staples carried by the staple holder slidingly engage the interior surfaces.

5. The hammer tacker according to claim 1 , wherein opposite side surfaces of the channel are formed by the fiber reinforced polymer material of the outer housing.

6. The hammer tacker according to claim 5 , wherein a transverse cross-section taken through a middle of the handle portion is devoid of metal except for the staple holder.

7. The hammer tacker according to claim 1 , wherein the channel comprises an upper surface formed by the fiber reinforced polymer material of the outer housing.

8. The hammer tacker according to claim 7 , wherein the channel is defined by an arched channel surface formed by the fiber reinforced polymer material of the outer housing.

9. The hammer tacker according to claim 8 , wherein the staple holder slidingly contacts portions of the inverted u-shaped channel surface formed by the fiber reinforced polymer material of the outer housing when moved between the use position and the refill position.

10. The hammer tacker according to claim 1 , wherein the fiber reinforced polymer material comprises a carbon fiber reinforced polymer material.

11. The hammer tacker according to claim 10 , wherein the carbon reinforced polymer material comprises between approximately 10% and approximately 40% by volume of carbon fiber.

12. The hammer tacker according to claim 1 , wherein the fiber reinforced polymer material comprises carbon fiber reinforced nylon.

13. The hammer tacker of claim 1 , wherein at least some of the ribs extend from both the top portion and at least one of the side portions of the inverted U-shaped portion to further connect the top portion and the side portion of the inverted U-shaped portion.
