Abstract

An exercise device is intended for strengthening a user's targeted muscle, wherein the user may manipulate the device without the necessity of a forceful grip that employs the user's conjunctive muscles. The device includes a housing having a pair of diametrically-opposed portions. The housing has an opening formed therein defined by the walls of the device. A weight is disposed in the housing. A plurality of extending and recessed ribs are arranged to provide for aligning the portions of the housing together and improving the structural integrity of the device. Ventilation slots are provided for improving air flow through the device, so as to avoid the build-up of heat therein. Lip segments are formed on the portions of the housing which are aligned to form a lip on the outer wall of the housing. The lip is disposed over the opening in which the user's hand is inserted.

Claims7

Dependent claims

In an exercise device, the combination of a housing including complementary diametrically-opposed housing halves, each of which is relatively thin-walled, the housing halves having peripheral edges mated together along a common midplane between the housing halves, means for securing the housing halves together, each of the housing halves having a concave recessed portion formed therein, the concave recessed portions being substantially aligned with one another when the housing halves are joined together, a weight means disposed within the concave recessed portions substantially at right angles to the common midplane between the housing portions, the housing having an opening formed therein substantially tangentially of the housing, whereby the hand of the user may be inserted through the opening in the housing and at least partially around the weight means radially thereof, the opening being bounded by an outer wall and an inner wall, the user's hand being disposed at least partially between the weight means and the walls of the housing, such that a forceful grip is not required by the user, and such that the necessity for employing the user's conjunctive adjoining muscles is substantially reduced, thereby substantially reducing the tendency to detract from the development of the user's targeted muscle, the inner wall and the outer wall of the housing halves having respective peripheral edges along which the housing halves mate, the inner wall of each housing half having a plurality of spaced-apart ribs formed adjacent to the inner wall, so that each of the ribs on one of the housing halves is positioned opposite a respective rib on the other of the housing halves, wherein the ribs, in alternating sequence, extend from the peripheral edge of the inner wall to form respective extending pins and alternating ribs are recessed from the peripheral edge of the inner wall, the respective pins extending a length from the respective housing half and joining the opposing recessed rib on the complementary housing half, the opposing recessed ribs being recessed by a length equal to the length of the extending pin.

In an exercise device, the combination of a substantially-spherical housing including a pair of complementary semi-spherical housing shells joined together along a common midplane diametrically of the spherical housing, each of the shells further having an inner wall having a peripheral edge and provided with a plurality of spaced-apart ribs disposed adjacent to the inner wall and substantially perpendicular to the common midplane between the housing shells, so that each of the respective ribs on the one of the housing shells is positioned opposite a respective rib on the other of the housing shells, the ribs, in alternating sequence, extending from the peripheral edge of the respective inner wall to form respective extending pins and alternate ribs being recessed from the peripheral edge of the respective inner wall, the respective pins extending a length from the respective housing shell and joining the opposing recessed rib on the complementary housing shell, the opposing recessed ribs being recessed by a length equal to the length of the extending pin thereby improving the structural integrity of the exercise device.
