Description

BACKGROUND

This disclosure relates to an improved jump rope.

Nowadays, physical fitness has been one of the major concerns of people around the world. Among all exercise equipment available, jump rope is one of the least expensive, most portable, and effective fitness equipment in the market. A standard jump rope uses a rope to attach two handles together. However, this design can cause the rope to become bound or tangled that can also prevent the rope from rotating smoothly when being used. Eventually a ball bearing method was developed to connect the rope and the handle of jump rope. This method uses a bearing that is attached within a jump rope handle. The ball bearing method allows the rope to move smoothly in all direction and eliminates the binding of the rope. However, due to frequent use, jump rope components such as the rope, attachments, and handles can be prone to wear-and-tear. Since, however, bearing attachments are usually enclosed within the handle, disassembly and replacement of the attachment can be time consuming and inconvenient for the user. Moreover, incorrect replacement of the bearing attachment can cause breakage to the handle, thus leaving the jump, rope inoperable and buying a new jump rope cannot be prevented. As a result such structure can be more expensive as well as inconvenient.

As such, it would be useful to have an improved jump rope.

SUMMARY

This disclosure relates to an improved jump rope. In one embodiment, an improved jump rope comprises a pair of tubular handles and a cord. Each of the tubular handles can comprise a void on a top portion, and the void can house a fastening mechanism. The jump rope can further comprise a pair of bearing swivels. Each of the bearing swivels can comprise a tapered hole on each end, the tapered holes mateable with a first fastener and second fastener. The first fastener can connect the handles and the bearing swivels. Each end of the cord can connect with the second fastener.

DETAILED DESCRIPTION

Described herein is an improved jump rope. The following description is presented to enable any person skilled in the art to make and use the invention as claimed and is provided in the context of the particular examples discussed below, variations of which will be readily apparent to those skilled in the art. In the interest of clarity, not all features of an actual implementation are described in this specification. It will be appreciated that in the development of any such actual implementation (as in any development project), design decisions must be made to achieve the designers' specific goals (e.g., compliance with system- and business-related constraints), and that these goals will vary from one implementation to another. It will also be appreciated that such development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the field of the appropriate art having the benefit of this disclosure. Accordingly, the claims appended hereto are not intended to be limited by the disclosed embodiments, but are to be accorded their widest scope consistent with the principles and features disclosed herein.

FIG. 1 illustrates a jump rope 100 comprising a pair of handles 101, a cord 102, and a pair of bearing swivels 103. Handle 101 can be the part of jump rope 100 that is purposely built to be gripped by hands. As such, handle 101 can be made of sturdy materials that include but are not limited to wood and hard plastics. In one embodiment, handle 101 can be coated or wrapped with a rubber material for comfort and to ensure a better grip on handle 101. In another embodiment, handle 101 can form a recessed portion to ensure comfortable grip and safe handling. Cord 102 can be made of pliable material such as rope, plastic fibers, and/or wire. Cord 102 can be long enough to allow rope material to move or rotate freely as handle 101 is maneuvered by the user. Bearing swivels 103 can comprise of tapered holes at both ends that can allow the snap and split ring to swing freely and pull from the center for perfect alignment. Bearing swivels 103 can be used to attach opposite ends of cord 102 with handles 101.

FIG. 2 illustrates a sectional view of handle 101 comprising a clevis pin 201, a sealed bearing 202, and a pair of retaining rings 203. Clevis pin 201 can be positioned within the middle top portion of handle 101. This ensures that bearing swivel 103 can be attached securely to handle 101. Clevis pin 201 can comprise of a clevis hole 204 at the top end and a head 205 at the bottom end. Clevis hole 204 can be used to accept a connector such as split rings that can be used to fasten bearing swivel 103 and clevis pin 201 together. As such, in one embodiment, the top end portion of clevis pin 201 can protrude from the top portion of handle 101. In another embodiment, handle 101 can have an extended portion covering the protruding part of clevis pin 201. In such embodiment, clevis pin 201 can be concealed within the extended part of handle 101. Head 205 can be used to ensure that clevis pin 201 is secured in place.

Sealed bearing 202 can be a device used to provide rotation within a fixed axis. As illustrated, sealed bearing 202 can be mounted into clevis pin 201 through sealed bearings orifice. In such position, sealed bearing 202 can rest at the bottom portion of clevis pin 201. As such, head 205 of clevis pin 201 can keep sealed bearing 202 in place.

Retaining rings 203 can be mounted into clevis pin 201 wherein sealed bearing 202 can be placed in between retaining rings 203. Retaining ring 203 can be a type of fastener that can hold and keep sealed bearing 202 from coming out of the handles 101.

FIG. 3 illustrates another embodiment of handle 101 further comprising a spacer 301. In such embodiment, spacer 301 can be placed in between sealed bearings 202. Spacer 301 can be a material used to support and fill in the void across the shaft of clevis pin 201. As such, retaining rings 203 can be placed at the outer end portions of sealed bearings 202. Thus, ensuring sealed bearings 202 are kept within the shaft of clevis pin 201.

FIG. 4 illustrates bearing swivel 103 attached to cord 102 and clevis pin 201. The tapered holes at both ends of bearing swivel 103 can have split rings 401 attached in each ends. As such, cord 102 can be inserted onto split rings 401 a and can be tightly bonded through the use of a fastener such as an oval sleeves 402. Split ring 401b can be inserted through clevis pin 401 to securely attach handle 101 with bearing swivels 103 and cord 102. In such structure, maneuvering handles 101 of jump rope 100 can allow rotation of clevis pin 201 that can prevent cord 102 from twisting and lagging. Moreover, this lessens the drag and friction between handles 101 and cord 102. Additionally, bearing swivel 103 that is attached externally from handles 101 can provide smoother rotation on cord 102. Minimum movement acted onto handles 101 can allow cord 102 to move freely in the desired direction.

Various changes in the details of the illustrated operational methods are possible without departing from the scope of the following claims. Some embodiments may combine the activities described herein as being separate steps. Similarly, one or more of the described steps may be omitted, depending upon the specific operational environment the method is being implemented in. It is to be understood that the above description is intended to be illustrative, and not restrictive. For example, the above-described embodiments may be used in combination with each other. Many other embodiments will be apparent to those of skill in the art upon reviewing the above description. The scope of the invention should, therefore, be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. In the appended claims, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein.”
