Description

Technology area

The claimed utility model relates to sports, to sports equipment used in training athletes, namely to skipping ropes, in particular to skipping ropes with a system for automatically winding the cable and storing it in the handle.

State of the art

A fairly large number of types of skipping ropes are known from the prior art. However, most of the well-known inventions and utility models are focused only on the modernization of handles in order to simplify the control of the length of the rope (or rope) of skipping ropes. In turn, the problem of storing the cable after the end of the workout remains open. Very few technical solutions are known in this area.

For example, a retractable skipping rope is known (see patent US 20170151457 A1 dated 01.06.2017), in which each handle contains a reel on which a cable can be wound. The cable can be stored in the first or second handle, or in both. To pull out the cable, the user pulls the first and second handles apart from each other, thereby unrolling the cable to the desired length for use. After completing the workout, the user initiates the twisting mechanism on one or both handles. The twisting mechanism includes a spring and ratchet teeth.

The disadvantages of the known technical solution include the method of fastening the cable, namely its fastening through a hole in the reel shaft. This method limits the use of steel core cables. In addition, the attachment of the reel to the handle without the use of a bearing makes it difficult for them to rotate relative to each other. Also, the disadvantages of the known technical solution include the absence of a mechanism that presses the cable to the reel. This can lead to jamming of the mechanism during the operation of the rope, since there is a possibility of chaotic winding of the cable onto the reel.

The closest in technical essence to the claimed utility model is a rope handle with a cable winding system (see patent AU 2002253703 (WO 2002094386 A1) from 25.07.2020). In the upper part of the handle there is a rotating wheel, on the side of which there is a spiral spring. The end of the cable is attached to a wheel around which it is wound. A control button is attached to the wheel, by pressing which the cable is locked. The cable is pulled out of the wheel to the desired length and, after completing the workout, the control button is pressed, as a result of which the cable is wound back into the handle.

The disadvantages of this handle mechanism are the inability to rotate the reel relative to the handle axis, as well as the absence of a mechanism that presses the cable to the reel, which, as in the previous technical solution, can lead to jamming of the mechanism during the operation of the rope. In particular, the cable can wind only on one section of the reel and abut against the outer body of the rope, thereby leading to jamming of the mechanism.

Disclosure of a utility model

The objective of the claimed utility model is to create an easily assembled rope handle with a cable storage system inside the handle.

The technical result of the proposed utility model is to improve the ease of use of the rope, namely, to simplify the adjustment of the cable length and improve the convenience of its storage.

To achieve the set task and the specified technical result, a rope with a mechanical twisting of the cable is proposed (see Fig. 2), containing a handle consisting of two halves of the handles (1) and (2), which are connected by means of screws (15) and (16) , a cable (13), which is attached to the spool (6) using a crimp end stop (12), at the end of which there is an eyelet, while the eyelet of the end stop is put on the rod (11), which is inserted into the hole in the spool (6), a ribbon spring (14), which is inserted into the cassette (3) and with the help of the tabs is fixed in it, while the cassette (3), the counterpart of the cassette (4) and the coil (6) are assembled into a single piece. The cable (13) is wound around the received part. Then the whole structure is mounted on the shaft of half of the handle (2). In this case, the ribbon spring is fixed on the shaft of the handle. The rope has a latch (5) for fixing the rope in the desired position. Uniform winding of the cable onto the spool is ensured by a pressure roller, which consists of three parts: a lever (7) and rollers (8) and (9). The roller is pressed against the cable spool by a spring (17), which is attached to the lever (7) at one end, and at the other end to the fixed spring tension regulator (10).

Implementation of the utility model

In this section of the description, the most preferred embodiment of the utility model will be given, which, however, does not limit other possible embodiments explicitly following from the materials of the application and understood by a person skilled in the art.

In the initial position, the cable (13) is wound around the rope reel. In this case, the spring (14) is not charged. The spring (17) of the pressure roller is in the maximally stretched position, since the pressure roller is maximally retracted from the spool (6) due to the cable wound on the spool. The latch (5) does not press on the cable.

When the cable is unwound, the ribbon spring comes into the cocked state. After unwinding to the required length, the cable is clamped with a lock (5). In this state, the rope is ready for use.

To wind the cable back onto the spool, unscrew the lock (5), the cable will be released and it will automatically wind up due to the elastic force of the charged tape spring.

Claims (1)
