Exercise device with removable weight
View Patent ↗An exercise device in which removable weight may be provided in a housing of the device. Two rotatable handles may be provided in the housing, permitting various hand orientations during exercise. The removable weight may be received within and/or removed from a cavity of the device.
1. An exercise device, comprising:
a housing;
a pair of rotatable handle assemblies within the housing; and
a cavity within the housing for receiving one or more removable weights, the cavity further defined by a plurality of weight sockets in parallel relation to one another and centrally located within the housing, each weight socket configured for retaining a corresponding weight adapted for lengthwise insertion into and removal from its corresponding socket.
2. The device of claim 1 , wherein each handle assembly of the pair is outboard the cavity on either side of the cavity.
3. The device of claim 1 , wherein the weights are shaped in a generally tubular form for lengthwise insertion into its corresponding weight socket of the cavity.
4. The device of claim 1 , wherein
a given weight is secured within a corresponding weight socket by rotating the weight in a first direction during insertion of the given weight into the weight socket, and
the given weight is fully removed from the weight socket by rotating the weight in a second direction.
5. The device of claim 1 , wherein
each weight includes a weight segment attached between first and second end caps, the first end cap adapted for insertion at an open end of the weight socket, the second end cap adapted so as to protrude from the housing at the weight socket open end when the weight is fully inserted into a closed end of the weight socket, the first end cap including at least one lug on a surface thereof, and
each weight socket includes a guide slot for receiving the at least one lug at the open end, at least one latch, and rotation means for forcing rotation of the weight in a first direction so that the at least one lug engages the at least one latch upon insertion of the weight towards the closed end within the weight socket.
6. The device of claim 5 , wherein the rotation means includes a flexible member providing tension against a face of the at least one lug as the weight is being inserted into the guide slot, and a ramp element provided at the closed end, the combination of the flexible member and ramp element imparting a force to cause the weight to rotate within the weight socket until the face of the at least one lug engages the at least one latch at the closed end of the weight socket.
7. The device of claim 5 , wherein
the weight segment further includes a recessed portion where the weight segment meets the first end cap and the first end cap includes a central bore therein containing a plunger and spring, the spring provided within the recessed portion and at least part of the bore for contacting the plunger, the plunger having a face that serves as a face of the first end cap, and
each weight socket includes a post at the closed end that engages the plunger face when the weight is fully inserted, biasing the plunger against the spring so as to force the at least one lug into continuous engagement with the at least one latch.
8. The device of claim 5 , wherein each weight includes a pair of lugs on opposing sides of the first end cap and each weight socket further includes a pair of primary latches for engaging a corresponding lug at the closed end and a pair of secondary latches, the secondary latches automatically engaging the opposing lugs upon accidental disengagement of the lugs from the primary latches to prevent unintended release of the weight from the weight socket.
9. The device of claim 5 , wherein the means for removing includes the protruding second end cap, at least one lug and at least one latch, wherein an inserted weight is removed by rotating the protruding second end cap in a direction opposite the first direction so that the at least one lug disengages the at least one latch.
10. An exercise device, comprising:
a housing having first and second ends,
a pair of rotatable handle assemblies within the housing, each handle assembly at a corresponding first end and second end of the housing, the housing adapted to secure a plurality of generally tubular-shaped weights, each insertable in a corresponding one of a plurality of weight sockets formed in the housing between the handle assemblies
a given weight adapted to be rotated in a first direction for insertion and retention into its corresponding socket, and adapted to be rotated in a second direction of rotation opposite the first direction so as to remove the weight from its corresponding socket.
11. An exercise device, comprising:
a housing,
a pair of rotatable handle assemblies within the housing, each handle assembly provided at a corresponding first end and second end of the housing; and
a plurality of weight sockets centrally located in the housing between the handle assemblies, each weight socket having an open end and a closed end for receiving a corresponding weight adapted for lengthwise insertion into the socket, the weight to be retained within the socket at the closed end.
12. The device of claim 11 , wherein
a given weight is secured within a corresponding weight socket by rotating the weight in a first direction of rotation during insertion of the given weight into the weight socket, and
the given weight is fully removed from the weight socket by rotating the weight in a direction different from the first direction.
13. The device of claim 11 , wherein
each weight includes at least one lug thereon,
each weight socket includes at least one latch, the weight rotating in a first direction during insertion within a corresponding weight socket so that the at least one lug engages the at least one latch to secure the inserted weight within the weight socket, and
the inserted weight is removed by rotating the weight in a second direction of rotation opposite the first direction so that the at least one lug disengages the at least one latch.
14. The device of claim 13 , wherein a given weight socket includes rotation means for imparting a force to cause the weight to rotate within the socket until the least one lug engages the at least one latch.
15. The device of claim 13 , wherein
each weight includes an interior cavity containing a plunger and spring, and
each weight socket includes a post that engages the plunger when the weight is fully inserted, biasing the plunger against the spring so as to force the at least one lug into continuous engagement with the at least one latch.
16. The device of claim 13 , wherein
each weight includes a pair of lugs on opposing sides of an end to be inserted into the socket,
each weight socket further includes a pair of primary latches for engaging a corresponding lug and a pair of secondary latches, the secondary latches automatically engaging the opposing lugs upon accidental disengagement of the lugs from the primary latches to prevent unintended release of the weight from the weight socket.
17. The device of claim 1 , wherein the handle assemblies rotate in the same plane into which the weights are insertable into the weight sockets.
18. The device of claim 10 , wherein the handle assemblies rotate in the same plane into which the weights are insertable into the weight sockets.
19. The device of claim 11 , wherein the handle assemblies rotate in the same plane into which the weights are insertable into the weight sockets.
