Definitions
- the invention relates to a voltage regulator for cables, particularly though not exclusively applicable to the regulation of the cable of 1 s brake levers in automobile vehicles.
- the retention brake lever is related to a cable that circulates to the brake system of the wheels of the vehicle, giving the circumstance that the tensioning of this cable produces irregularities in braking, making a system necessary or device that regulates the cable tension at all times.
- the general technique used in this application is to act on the cable or on a rod connected to it at the beginning of the system, so that on said cable or on said rod a device that allows when the cable has been loosened , the device in question facilitates the passage of the same or of the rod in the direction of the brake lever, while avoiding the opposite circulation, thereby achieving a permanent regulation of the brake capacity.
- EP. A.0040574 and EP. A.0754135 a regulation device based on a box-like element with a wedged end, inside which there are facing wedges that are accommodated at the corresponding ends of the box.
- the wedges in turn have opposite teeth, between which a rod connected to the cable runs.
- SUBSTITUTE SHEET (RULE 26) serrated rod that runs between two pieces also equipped with teeth and forced by springs against it, which allows the transfer of the serrated rod in only one direction.
- Another object of the invention is a regulator that is economical to manufacture.
- Another object of the invention is a regulator that allows the mechanism to be zeroed out extraordinarily easily.
- the regulator of the invention starts from a mechanism composed of a rotating lever associated with a base body and on said base body.
- the latter is related to a cable, the furthest end of which is related to the brake device, for example the wheel shoes of a motor vehicle.
- the base body incorporates a spring connected to the cable directly or to an initial rod associated with the cable.
- the spring has a logical tendency to pull the cable, so that it acts against the brake system. However, and due to the successive operations actuation of the lever, the cable is stretched losing its effectiveness.
- the base body is provided with a spirally wound spring with one end thereof fixed to the base body and with the other end related to the cable or with a section of threaded or serrated rod arranged at the beginning of said cable.
- the cable crosses the hollow interior of an elongated box which is fixed to the base body d forms a unique whole with it. Inside the box a carriage fits properly between the sides of the box and connected to the cable.
- the cable connection to the car is made by splitting it, so that the ends are related to the beginning and the end of the mentioned car.
- the car incorporates two pieces of elliptical plan mounted on axes parallel and perpendicular to the longitudinal plane of the car, which have mutually indented sides, while the outer sides of both protrude from the sides of the car to the walls. of the box, these outer sides can be provided with teeth roughness for their interlocking in the walls of the box.
- the d-axis axes that collect the elliptical pieces are arranged in the center of the same and on one of the sides, on the side of the exit, a strap-type spring, shaped, rests against the lateral surfaces of both, being this strap supported in turn at a fixed point of the car, so that it has a tendency to press on the two elliptical parts so they remain, in turn, secured against ⁇ ral late to the CAJ.
- the box is also provided with a hole, on the side of the exit, which communicates with a slot portion of the carriage itself also made on the side of the exit, in which holes the rounded end is housed as a serrated recess made in the end of a piece or lever articulated to the brake body-base.
- the end of the lever in question when rotating in this base body is placed on the cable, immobilizing the assembly in the zeroing or assembly initiation operations.
- the outer lateral surfaces of the two elliptical gears of the carriage can be serrated, malleable, scratched ... etc., so as to facilitate their proper crimping with the lateral surfaces of the carriage.
- the car logically has the appropriate means to receive and secure the cable d where appropriate the cable and the hairpiece.
- a variant of this basic solution of the invention is established on the basis of two elliptical pieces with lateral ends provided with a single tooth.
- the car can include a single elliptical piece that rests on a single side of the box, the rest being arranged in identical conditions to those described above.
- the box is constituted on its inner sides with teeth, which have a slope perpendicular to the longitudinal direction of the box and another inclined in the direction of the body-base. Inside this box runs a set associated on the one hand to the cable that comes from the helical spring of the base body and on the other to the cable or the insert that is directed towards the brake.
- a spring is arranged which acts against the two parts when the tension of the cable protruding from the case towards the brake decreases due to use.
- the tension of the helical spring disposed on the base body forces the assembly towards said helical spring, whereby the cable is re-tensioned returning to its initial position.
- These two pieces have two inclined colisa grooves each, in a direction that forms an angle with the direction of the cable. These grooves are crossed by pins secured in the box in which the two pieces run inclined away or near their sides with shapes of the cable d of the hairpiece.
- the box includes fins on the side of the helical spring on which the springs resting frontally to the wedges rest, which in turn has a centered hole that allows the passage of the cable, from the body-base side.
- the front faces of the wedges of the narrowest side of the box are in solidarity with pins that protrude outside the mentioned box, which are capable of being manually operated from the outside for manual unlocking of the assembly.
- the aforementioned pins meet in a projection that provides a surface area to be pressed by the user, which is provided with a central hole that allows the passage of the cable or the hairpiece in the direction of the brake.
- the insert can be immobilized for zeroing through the lever, as noted above.

- one of the housings in turn equipped with a hole in which the aforementioned sideburns play.
- This locking piece has at its angle and externally, an outstanding bulge which is housed in a hole made in the projection, on which it can rotate.
- one is of a larger dimension and is smooth and the smaller one is provided with an protruding portion as a tab limiting the rotation of said locking piece.
- the external bulge is introduced into the hole of the aforementioned projection, blocking the rotation of the housings and in the other of the two positions, said introduced area is released, as will be noted later. with reference to the accompanying sheet of drawings.
- a box similar to the one described above is placed on one of the housings or lever bodies, which receives wedges, forced by two springs that bind them against a wedged end of said box, under general operating conditions equal to those mentioned.
- the box can be eliminated with an internal mechanism, " replacing it with a circular piece housed in the lever pin and housings, which circular piece is provided with teeth on its lateral surface and is associated with turn to a ratchet endowed with -ludients in contrast to those of that one, arranging this ratchet in the lever body.
