Abstract

An exercise device includes a rigid handle having a lower end and an upper end. The upper end is adapted for grasping by a person's hand, and the lower end is fixed with a shaft receiver. A bottom end of the shaft receiver is adapted for receiving a top end of a rigid shaft that is adapted to receive one or more weights. A weight stop projects away from a lower end of the rigid shaft to prevent the weights from sliding off of the rigid shaft. In use, with one or more of the weights fixed on the rigid shaft, and with the top end of the rigid shaft fixed with the shaft receiver, the person may grasp the handle to perform exercises. A latch of the shaft receiver selectively locks the rigid shaft with the shaft receiver. The shaft and shaft receiver may include cooperative screw threads.

Claims (30)

1. An exercise device for grasping by a person's hand and for holding one or more weights, comprising:

a rigid handle having a lower end and an upper end, the upper end adapted for grasping by the person's hand;

a weight attachment mechanism having a shaft receiver at a lower end of the rigid handle and a rigid shaft that is receivable within the shaft receiver and adapted to receive one or more weights thereon, wherein the shaft receiver defines internal helical threads and a hole extending through a sidewall of the shaft receiver, wherein the rigid shaft defines external helical threads and an axially extending catch, and wherein the rigid shaft is attachable to the shaft receiver by inserting the rigid shaft into the shaft receiver and rotating the rigid shaft in a first direction so that the internal and external threads screw together;

a weight stop projecting away from a bottom end of the rigid shaft and adapted to prevent the weights from sliding off of the rigid shaft; and

a latch pivotally attached to the shaft receiver so that the latch is movable within the hole to engage with the catch to inhibit rotation of the shaft in a second direction opposite the first direction and to release with the catch to allow removal of the rigid shaft from the shaft receiver.

2. The exercise device of claim 1 wherein the handle and the weight attachment mechanism are formed with a metallic material.

3. The exercise device of claim 2 wherein the handle is welded to the shaft receiver of the weight attachment mechanism.

4. The exercise device of claim 2 wherein the handle is fixed at least partially through the shaft receiver of the weight attachment mechanism.

5. The exercise device of claim 1 wherein the handle is formed into a loop.

6. The exercise device of claim 5 wherein the upper end of the handle has a straight portion, and wherein the lower end of the handle has a curved portion.

7. The exercise device of claim 1 wherein a pivot axis of the latch is parallel to an axial direction of the rigid shaft.

8. The exercise device of claim 1 wherein the latch is urged with a spring inwardly, and wherein a leading edge of the catch and a leading edge of the latch are cooperatively sloped to allow the catch to move the latch outwardly from the shaft receiver to allow the catch to pass under the latch, after which the latch is urged back inwardly by the spring to engage the catch, and whereby to unscrew the rigid shaft from the shaft receiver the person manually pulls the latch outward while unscrewing the handle relative to the rigid shaft.

9. An exercise device for grasping by a person's hand and for holding one or more weights, comprising:

a handle including a cylindrical base portion and a grasping portion, the cylindrical base portion having an outer circumferential surface and having an inner circumferential surface defining internal helical threads, wherein the base portion further defines a hole extending from the outer surface to the inner surface;

a weight holder including a shaft adapted to receive one or more weights and a weight stop attached to a lower end of the shaft and adapted to prevent the one or more weights from sliding off of the shaft, the shaft including an upper portion defining external helical threads and defining an axially extending catch, wherein the weight holder is attachable to the handle by inserting the upper portion of the shaft into the base portion and rotating the shaft in a first direction so that the internal and external threads screw together; and

a latch including an end pivotally attached to the outer circumferential surface of the base portion and a curved tip receivable through the hole to engage with the catch to inhibit rotation of the shaft in a second direction opposite the first direction to secure the weight holder to the handle.

10. The exercise device of claim 9 wherein the latch is pivotal between a latching position in which the tip and the catch are connectable and an unlatched position in which the tip is radially outboard of the catch.

11. The exercise device of claim 10 wherein the latch is biased to the latching position.

12. The exercise device of claim 11 wherein the latch is biased by a spring.

13. The exercise device of claim 9 wherein a pivot axis of the latch is parallel to an axial direction of the cylindrical base portion.

14. The exercise device of claim 9 wherein a leading edge of the catch and a leading edge of the tip are cooperatively sloped to allow the tip to ratchet over the catch in the first direction.

15. The exercise device of claim 9 wherein the catch is located between the external threads and the weight stop.

16. The exercise device of claim 9 wherein the shaft includes a main portion extending between the upper portion and the lower end, the main portion having a first diameter that is larger than a second diameter of the upper portion.

17. The exercise device of claim 16 wherein the outer surface of the cylindrical base portion has a third diameter that is equal to the first diameter.

18. The exercise device of claim 9 wherein the cylindrical base portion includes a boss disposed on the outer surface, and wherein the latch includes a pin extending though the boss and the end of the latch.

19. An adjustable weight kettlebell comprising:

a handle including a base portion defining internal helical threads and a hole extending through a sidewall of the base portion;

a shaft adapted to extend through one or more weights, the shaft defining external helical threads and an axially extending catch, wherein the shaft is attachable to the handle by inserting an upper portion of the shaft into the base portion and rotating the shaft in a first direction so that the internal and external threads screw together;

a weight stop attached to a lower end of the shaft and adapted to prevent the one or more weights from sliding off of the shaft; and

a latch pivotally attached to the base portion so that the latch is movable within in the hole to engage or disengage with the catch to inhibit rotation of the shaft and permit rotation of the shaft.
