Abstract

A modular impactor head includes a load transfer member, a base, and a locking assembly. The base defines a space sized and configured to receive the load transfer member therein and to constrain movement of the load transfer member relative to the base in a plurality of directions. The locking assembly is sized and configured to constrain movement of the load transfer member with respect to the base in at least one direction such that the load transfer member is fixed to the base.

Claims (29)

1. A modular impactor head, comprising:

a load transfer member;

a base including a plurality of sidewalls extending from a bottom wall to define a space sized and configured to receive the load transfer member therein and to constrain movement of the load transfer member relative to the base in a plurality of directions, and at least two of the sidewalls each defining a respective slot; and

a locking assembly sized and configured to constrain movement of the load transfer member with respect to the base in at least one direction such that the load transfer member is fixed to the base,

wherein the bottom wall of the base defines a cavity sized and configured to receive a locking shaft of the locking assembly, wherein a bottom wall of the load transfer member defines a hole sized and configured to receive a portion of a locking shaft of the locking assembly.

2. The modular impactor head of claim 1 , wherein the locking assembly includes a biasing member sized and configured to be received within the cavity defined by the bottom wall of the base.

3. The modular impactor head of claim 1 , wherein the locking shaft defines a slot sized and configured to receive a pin.

4. The modular impactor head of claim 1 , wherein the load transfer member includes protrusions sized and configured to be received within the slots defined by the sidewalls of the base.

5. The modular impactor head of claim 1 , wherein the base includes a coupling member extending from the base in an opposite direction with respect to a direction in which the sidewalls extend, the coupling member configured to be engaged by a handle.

6. The modular impactor head of claim 5 , wherein the coupling member includes a feature for preventing rotation of the impactor head with respect to the handle.

7. A modular impactor head, comprising:

a load transfer member including a pair of tabs extending from opposite side surfaces of the load transfer member;

a base including a plurality of sidewalls extending from a bottom wall to define a space sized and configured to receive the load transfer member, at least two of the sidewalls defining slots and the bottom wall defining a cavity, the slots sized and configured to slidably receive the tabs extending from the side surfaces of the load transfer member; and

a locking assembly sized and configured to be received within the cavity and to lock the load transfer member to the base,

wherein the load transfer member includes protrusions sized and configured to be received within the slots defined by the sidewalk of the base.

8. The modular impactor head of claim 7 , wherein the locking assembly includes an elongate shaft sized and configured to be received in the cavity, the elongate shaft defining a slot configured to be engaged by a pin.

9. The modular impactor head of claim 8 , wherein the locking assembly includes a biasing member sized and configured to be received within the cavity defined by the bottom wall of the base.

10. The modular impactor head of claim 8 , wherein a bottom wall of the load transfer member defines a hole sized and configured to receive a portion of the elongate shaft.

11. The modular impactor head of claim 7 , wherein the base includes a coupling member extending in a direction away from the sidewalls, the coupling member for coupling the impactor head to a handle.

12. The modular impactor head of claim 11 , wherein the coupling member includes a shoulder and a reduced diameter area.

13. A modular impactor head, comprising:

a load transfer member including a pair of tabs extending from opposite side surfaces of the load transfer member;

a base including a plurality of sidewalls extending from a bottom wall to define a space sized and configured to receive the load transfer member, at least two of the sidewalls defining slots and the bottom wall defining a cavity, the slots sized and configured to slidably receive the tabs extending from the side surfaces of the load transfer member; and

a locking assembly sized and configured to be received within the cavity and to lock the load transfer member to the base,

wherein the locking assembly includes an elongate shaft sized and configured to be received in the cavity, the elongate shaft defining a slot configured to be engaged by a pin, and

wherein a bottom wall of the load transfer member defines a hole side and configured to receive a portion of the elongate shaft.

14. The modular impactor head of claim 13 , wherein the locking assembly includes a biasing member sized and configured to be received within the cavity defined by the bottom wall of the base.

15. The modular impactor head of claim 13 , wherein the base includes a coupling member extending in a direction away from the sidewalls, the coupling member for coupling the impactor head to a handle.

16. The modular impactor head of claim 15 , wherein the coupling member includes a shoulder and a reduced diameter area.
