Abstract
Claims

A handle system includes a body extending between a first end and a second end. The handle system also includes a slot extending, at least partially, in the body, the slot forming a cavity. The handle system further includes a carrier arranged, at least partially, within the slot, the carrier further comprising a friction locker and at least one arm coupled to the friction locker, the at least one arm being rotatable about the friction locker. The handle system also includes a cap arranged on at least one of the first end or the second end. The handle system further includes a blade coupled to the at least one arm, the blade being rotatable about the axis between a retracted position where the blade is positioned within the slot and an extended position where the blade extends outwardly from the body.

The invention claimed is:

1. A multiple blade handle system, comprising:

a body extending between a first end and a second end thereof;

a first slot extending, at least partially, in the body, the first slot forming a cavity, the first slot arranged at the first end;

a first carrier arranged, at least partially, within the first slot at the first end, the first carrier further comprising a friction locker and at least one first arm coupled to the friction locker, the at least one first arm being rotatable about the friction locker;

a cap arranged on at least one of the first end and the second end;

a first blade coupled to the at least one first arm, the first blade being rotatable about a first axis between a first retracted position where the first blade is positioned within the first slot and a first extended position where the first blade extends outwardly from the body;

a second carrier arranged, at least partially, within a second slot positioned at the second end; and

a second blade coupled to at least one second arm of the second carrier, the second blade being rotatable about a second axis between a second retracted position where the second blade is positioned within the second slot and a second extended position where the second blade extends outwardly from the body.

2. The multiple blade handle system of claim 1, wherein the body further comprises:

an extendable body portion, the extendable body portion increasing a length of the body by adjusting the position of the extendable body portion relative to a first body portion of the body by means of a sliding mechanism of the multiple blade handle system.

3. The multiple blade handle system of claim 1, wherein the first blade and the second blade are independently rotatable.

4. The multiple blade handle system of claim 1, further comprising:

a third arm coupled to the first carrier; and

a third blade coupled to the third arm, the third blade being rotatable about the first axis between a third retracted position where the third blade is positioned within the first slot and a third extended position where the third blade extends outwardly from the body.

5. The multiple blade handle system of claim 4, wherein the second blade and the third blade are independently rotatable.

6. The multiple blade handle system of claim 4, wherein the first blade is a different size than the third blade.

7. The multiple blade handle system of claim 1, further comprising:

a rotation limiter associated with the friction locker, wherein the rotation limiter restricts rotation of the first blade about the first axis.

8. The multiple blade handle system of claim 1, wherein the at least one first arm includes a tongue and the first blade includes a groove, the groove receiving the tongue to couple the first blade to the at least one first arm.

9. A multiple blade handle system, comprising:

a body;

a cavity formed within the body;

a first carrier, having a plurality of arms, movable within the cavity, the plurality of arms being rotatable about a first axis of first carrier;

a rotation limiter positioned proximate the plurality of arms and arranged within the cavity, the rotation limiter blocking rotation of the plurality of arms beyond a predetermined position;

a first blade coupled to a first arm of the plurality of arms;

a second blade coupled to a second arm of the plurality of arms;

a second carrier, having a third arm, the third arm being rotatable about a second axis of the second carrier; and

a third blade coupled to the third arm, the third arm rotatable about the second axis;

wherein rotation of the first arm and the second arm is independent of rotation of the third arm.

10. The multiple blade handle system of claim 9, further comprising:

a friction locker associated with the first carrier and arranged coaxially with the first axis, the friction locker restricting rotation of the first arm, about the first axis, when a rotational force is less than a set amount and enabling rotation of the first arm, about the first axis, when the rotational force is greater than the set amount.

11. The multiple blade handle system of claim 9, further comprising:

a cap covering at least a portion of the cavity, the cap being coupled to the body.

12. The multiple blade handle system of claim 9, further comprising:

a textured region along at least a portion of the body.

13. The multiple blade handle system of claim 9,

wherein rotation of each of the first arm and the second arm is independent of one another.

14. The multiple blade handle system of claim 13, wherein the first blade is a different size than the second blade.

15. The multiple blade handle system of claim 9, further comprising:

an extending body portion of the body, the extending body portion being axially translatable away with respect to a first body portion of the body via a sliding mechanism such that a length of the body is adjustable.
