Abstract

An improved jump rope handle and method of assembling the same. The jump rope handle includes a head. The head includes a channel, a set hole perpendicular to the channel, and a set mechanism adjustably insertable into the set hole. The jump rope handle further includes a grip. The grip includes a cylindrical member, first and second bearings arranged along the cylindrical member, an inner bushing arranged along the cylindrical member between the first and second bearings, and a sleeve around said inner bushing, said bushing being fixedly attached to an inner surface of the grip. An end portion of the cylindrical member is fixedly attached to the head whereby the cylindrical member and the head rotate together about a same axis. The channel of the head is configured to receive a rope. The set mechanism is configured to be inserted into the set hole to secure the rope.

Claims

1. A jump rope handle, comprising:

a head, including;

a channel;

a set hole perpendicular to the channel; and

a set mechanism adjustably insertable into the set hole;

a grip, including;

a cylindrical member axially spaced apart from an inner surface of the grip;

first and second bearings arranged along the cylindrical member, the bearings having an inner race and an outer race, with the inner races extending about the cylindrical member and with the outer races axially spaced apart therefrom;

an inner bushing extending around the cylindrical member between the inner race of each of the first and second bearings and spaced apart from the inner surface of the grip with the inner bushing being independently movable relative to the inner surface of the grip; and

a sleeve extending around said inner bushing, said sleeve having an outer diameter originally larger than a diameter of the inner surface of the grip, said sleeve being fixedly attached to the inner surface of the grip by a compression fit resulting from press-fitting the cylindrical member, the first and second bearings, the inner bushing, and the sleeve into the grip, and the sleeve being interfaceable with the outer race of each of the first and second bearings,

wherein an end portion of the cylindrical member is fixedly attached to the head whereby the cylindrical member and the head rotate together about a same axis,

wherein the channel of the head is configured to receive a rope, and

wherein the set mechanism is configured to be inserted into the set hole to secure the rope.

2. The jump rope handle of claim 1, wherein the sleeve is fixedly attached to the inner surface of the grip by adhesive.

3. The jump rope handle of claim 1, wherein the end portion of the cylindrical member is fixedly attached to the head by adhesive.

4. The jump rope handle of claim 1 wherein the sleeve has an upper end and a lower end, and the inner bushing has an upper end and a lower end, the upper end of the sleeve and the upper end of the inner bushing align with each other, with the lower end of the sleeve being spaced apart from the lower end of the inner bushing.

5. A jump rope handle, comprising:

a head, including;

a bolt hole;

a channel perpendicular to the bolt hole;

a set screw hole in line with the bole hole and perpendicular to the channel; and

a set screw adjustably screwed into the set screw hole;

a grip including a shaft therein axially spaced apart from an inner surface of the grip, the shaft including;

a bolt;

first and second bearings arranged along the bold, the bearings having an inner race and an outer race, with the inner races extending about the bolt and the outer races being axially spaced apart therefrom;

an inner busing extending around the bolt between the inner race of each of the first and second bearings and spaced apart from the inner surface of the grip; and

a sleeve extending around said inner bushing, said sleeve having an outer diameter originally larger than a diameter of the inner surface of the shaft of the grip, an outer surface of the sleeve being fixedly attached to the inner surface of the shaft of the grip by a compression fit resulting from press-fitting the bolt, the first and second bearings, the inner bushing, and the sleeve into the shaft of the grip, and the sleeve being interfaceable with the outer race of each of the first and second bearings with the inner bushing being independently movable relative to the inner surface of the grip,

wherein a threaded end of the bolt is screwed into the bolt hold of the head and attached thereto whereby the bolt and the head rotate together about a same axis,

wherein the channel of the head is configured to receive a rope, and

wherein the set screw is configured to be screwed into the set screw hole to secure the rope.

6. The jump rope handle of claim 5, wherein the sleeve is fixedly attached to the inner surface of the shaft of the grip by adhesive.

7. The jump rope handle of claim 5, wherein the threaded end of the bolt is fixedly attached to the bolt hole of the head by adhesive.

8. The jump rope handle of claim 5 wherein the sleeve has an upper end and a lower end, and the inner bushing has an upper end and a lower end, the upper end of the sleeve and the upper end of the inner bushing align with each other, with the lower end of the sleeve being spaced apart from the lower end of the inner bushing.
