Abstract
A dumbbell has a planar base allowing it to be supported in a stable manner upon the ground, for instance while the user holding a pair of dumbbells performs exercises such as push ups. A compliant sheet on the base provides a high friction slip-resistant face. A pair of flanges disposed on the base and protruding from the base for mounting a handle therebetween and the base has a waisted form. Weights are provided for adjusting the total mass of the dumbbell. Complementary tongue and groove couplers are provided on each weight and on the flanges whereby each weight is releasably fastened to the device.
Claims11
A dumbbell including:
- a rigid base having first and second opposing sides, the first side being substantially planar and having means for supporting the dumbbell upon a support surface;
- a pair of flanges fixed to the base and protruding in a first direction outwardly from the second side, each flange having an inner and an opposing outer side;
- a handle having opposing ends mounted to respective ones of the flanges so as to span between the inner sides;
- an aperture provided between the handle and the base for receiving the user's fingers;
- two weights;
- a complementary elongate tongue and a groove pair by which each weight is releasably fastened to the base, wherein one of the tongue and groove pair is disposed on each weight and the other of the tongue and groove pair is fixed to the base, disposed on the outer side of each flange;
- and
- a latch for preventing relative sliding movement between the tongue and groove of each pair.
An exercise device including:
- a rigid base having first and second opposing sides and longitudinally opposing end portions, the first side having a planar surface, the longitudinally opposing end portions separated by a waist portion;
- a compliant sheet fixed to the first side to provide a planar slip-resistant face for supporting the device;
- a pair of flanges, each disposed proximate one of the longitudinally opposing ends and arranged to protrude in a first direction away from the second side and joined by a web portion disposed adjacent the second side;
- a handle, opposing ends of the handle mounted to respective ones of the flanges;
- an aperture provided between the handle and the base for receiving the user's fingers;
- a pair of weights;
- a tongue and groove coupler pair releasably connecting each weight to an outer side of a respective flange;
- and
- a latch cooperating with each tongue and groove coupler pair for preventing relative sliding movement between the respective weight and flange.
