Definitions
- the invention relates to a tool for tensioning a rope of a racket, by resting on the outside of the racket frame, introducing the rope between the jaws formed by two half-cylinders (1,2) by exerting a push. progressive on the handle until the incorporated device signals that the desired tension of the rope is reached.
- the purpose of the tool according to the invention is to make it possible to cord or repair a cord using the manual tensioner at all times. Its size and very low weight make it easy to take with you.
- the advantage of the tool for tensioning the strings is that its use is very simple.
- the position in front of the connecting axis (3) relative to the fulcrum on the frame of a racket and relative to the handle serving as a lever, allows the rope to be plucked and tightened in a single movement.
- the other advantage is the rounded and hollow shape, Fig. 2, of the two half-cylinders allowing a cord to be wrapped around them and in addition to resting on the frame without lateral sliding.
- the part (3), Fig.3, by its shape and its place makes the introduction of a rope possible on both sides inside the jaws.
- the hole (15) for connecting the part (3) is crossed by a conical axis (4) provided with a screw thread at its end (17), by screwing the axis the distance between the jaws, this makes it possible to tighten coders of different diameters in an optimal way.
- a control device (14) is incorporated inside the handle. The device warns with an acoustic signal as soon as the desired voltage is reached.
- Fig.l shows the tool according to the invention for tensioning a string of a racket seen from the side.
- Fig.2 shows the tool seen from the front.
- Fig.3 shows the connecting piece (3) and the axis (4) in detail.
- Fig.4 shows the parts (7) (8) and the axis (10) in detail.
- the two half-cylinders (1,2) serving as jaws, are interconnected by the device (3).
- the connecting device (3) pivots around the axis (4).
- the axis (4) according to Fig.3, is in its part where it passes through the opening (15), of conical shape (16).
- the thread (17) at the end of the axis (4) allows adjustment of the distance between the jaws (1,2).
- the hole (15) of the connecting piece (3) is tapped in a conical shape with the same angle of inclination as the conical part (16) of the axis (4).
- the diameter of the opening (15) of the part (3) corresponds to the diameter, at the widest point in its conical part (16), of the axis (4).
- the piece (7) in the form of a fork, is fixed at the top of the half-cylinder (1) with an inclination of about 60.
- the upper section of the part (8) is located inside the tube (11), an opening (9) tapped in length allows a movement perpendicular to the axis (4) towards the inside of the tube (11).
- the pointed part (18) of the part (8) is wedged by the spring (13) against the inclined bottom (19) at 45 ° from the part (7)
- the handle pivots around the axis (10) when the pressure force exceeds the pressure of the spring (13) on the part (7) which abuts against the inclined wall (19).
- the pressure of the spring (13) is adjustable by the screw (12) located at the end of the tube (11).
- the inclined wall (19) causes the part (8) to move towards the inside of the tube (11) and, by this movement, releases the device (14).
