Description

"WIND-UP LEASH WITH PERFECTED DEVICE FOR CONTROLLED
AUTOMATIC BRAKING"
**********
TECHNICAL FIELD
This invention concerns a perfected device for controlled automatic braking in' particular for the cord of a leash with automatic winder. More in particular, this invention refers to an automatic braking device for a wind-up leash suitable for controlling pets while walking them.
BACKGROUND ART It is a known fact that pets that have to be walked, for example dogs of various sizes, are usually accompanied using leashes with a cord or strap which is variable in length since it is wound up inside a respective winding device gripped by the user; in this way the animal is free to move at a certain distance away from the person accompanying it who thus avoids being subjected to sudden jerks.
One drawback is represented by the fact that when walking in public places, current regulations foresee that a maximum distance of the animal from the person accompanying it must be respected for obvious reasons of safety and thus, in this case, it is obligatory to use a fixed-length lead or one which can be blocked at predetermined length. Various solutions have already been proposed, for example patent no. VR94A00066 dated 27/7/1994 in the name of the applicant hereto.
A drawback that has not yet been overcome concerns the rapid rewinding of the cord which, in certain cases, can be dangerous for the user who may be exposed to "whiplash" blows of the spring clip which may accidentally become unhooked from the pet's collar.
DESCRIPTION OF THE INVENTION
The aim of the present invention is to provide a perfected braking device which eliminates or significantly reduces the drawbacks mentioned above.
The present invention also aims to provide a perfected braking device which is easy to produce and thus having a limited production cost so as to be advantageous also from a financial point of view.
A further aim of the present invention is to provide a leash which can be easily applied to any type of collar.
This is achieved by means of a perfected device for controlled automatic braking, in particular for the cord of a wind-up leash, with the features described in the main claim.
The dependent claims describe advantageous forms of embodiment of the invention. The perfected device for controlled automatic braking according to the present invention comprises a wind-up leash consisting of a casing designed to contain at least one reel, equipped with means of rotational elastic winding and designed to wind up a cord, this cord protruding from the leash and presenting means for hooking it onto a collar or the like at its free end. According to a preferred form of embodiment of the invention, the device presents a lever, one arm of which is equipped with elastic loading means designed to press against the cord while the opposite arm is equipped with a trigger protruding from the casing and designed to activate the lever from the outside.
According to the invention, the elastic loading means of the lever arm presents portions with different coefficients of elasticity. The end of the lever arm in contact with the wound-up cord is advantageously equipped with a pad to ensure that the cord is not completely wound onto the reel, leaving a minimum portion of cord protruding from the casing.
The pad can block or release the rotation of the reel by means of direct control from the outside by activating the trigger.
According to another advantageous form of embodiment of the invention, the end of the lever arm can be fitted with a roller designed to reduce the abrasion of the cord due to friction of the pad.
According to a further advantageous form of embodiment of the invention, the device includes a clamp guided inside an appropriate guide in the casing of the leash. According to this form of embodiment, one end of the clamp comprises an arm, which may be hinged to this end, equipped with a. pad or roller designed to interact with the cord wound on the reel. The other end of the clamp protrudes from the casing of the leash and is equipped with a manually activated slider. This clamp is permanently stimulated by an appropriate spring, which may be an integral part of the clamp or fixed to it, in such a way that the pad or roller comes into contact with the cord.
According to all the forms of embodiment, the clamp or the lever can be equipped with a coupling retainer which makes it possible to exclude the activation of the braking device, which otherwise acts automatically and independently of the user's manual action.
Moreover, both the clamp and the lever can be part of a more complex mechanism designed to ensure blocking and releasing of the cord in different positions and controlled end-of-travel braking with different decelerations that can be controlled by the user.
Finally, the leash can comprise a device inside the casing to detect the extent to • which the cord is wound onto the reel and an indicator which informs the user of the immediate condition of use.
DESCRIPTION OF THE DRAWINGS
Other features and advantages of the invention will become evident on reading the following description of one form of embodiment of the invention, given as a non- binding example, with the help of the enclosed drawings, in which: figure 1 shows a side elevation, in cross section, of a leash equipped with a braking device according to the invention; figure 2 shows an enlarged cross-section along the line II-II in figure 1; figure 3 is a cross-section, similar to figure 2, according to another form of embodiment; and figure 4 shows a view similar to figure 1 according to another form of embodiment.
DESCRIPTION OF ONE EMBODIMENT
In the figures, the reference number 10 generally indicates a wind-up leash, in the case in question a leash for pets equipped with a controlled automatic braking device 11.
The leash 10 comprises a casing 12 consisting of two shells 13 fixed together by means of screws and enclosing an internal space designed to house a reel 14 on which a cord or strap is wound 15.
The shells 11, which can be made from moulded composite plastic material, define a handgrip 16, an opening 17 for the cord 15 and a cavity 18 designed to house the reel 14 which rotates around a pin 19.
An internal portion of the reel 14 is equipped with a rotation elastic return means, for example a spiral spring 20, one end of which is fixed to the reel 14 while the other end is fixed to the shell 13 near the pin 19. • According to this device, the spiral spring 20 is loaded by unwinding the cord 15 from the reel 14 restoring gradually increasing elastic energy the more the cord 15 is unwound.
The reel 14 is equipped with a series of angled radial projections 21, equally spaced around its outer edge, each having a respective surface 22 designed to strike against a temporary retainer as described in detail below.
Inside the casing 12, in the upper part above the reel 14, is a pin 23 on which a rocker arm 24 is fixed, whose end 25 near the reel 14 is designed to strike against the surface 22 of a projection 21 causing the temporary blocking of the reel 14 with consequent immobilization of the cord 15.
The rocker arm 24 presents a slot 26 which houses the pin 23 and is larger than the pin so that it can not only swivel around the pin 23 but also move backwards and forward with respect to the pin.
The rocker arm 24 has one end 27, facing the handgrip 16, integral with a pushbutton 28 protruding from the casing 12 in such a way that it can be activated by the user.
The rocker arm 24 can also be equipped with an arm 29 designed to temporarily engage in a respective slit 30 in the shell 13 in order to block the pushbutton 28 to prevent accidental elongation or shortening of the cord
15 while walking the pet.
Shifting of the pushbutton 28 moves the end 25 of the rocker arm against the projection 21 and the end of the arm 29 into the slit 30; this makes it possible to block the cord without the need for any further manual action.
The rocker arm 24 can be equipped with additional mechanisms, according to background art, aimed at achieving shock-absorbed braking of the reel 14 and consequent control of both the exit and the return of the cord 15 in the casing 12.
The controlled automatic braking device 11 is located in the lower part of the casing 12 and comprises a lever
31, which swivels around a pin 32 integral with the shell
13, one arm 33, close to the reel 14, being equipped with elastic loading means.
The elastic loading means can consist of a projection 34 integral with the arm 33 and curved, in a contrasting direction to the rotation of the reel 14 for the unwinding of the cord 15, towards the outer edge of the casing 12 to strike the shell 13. As can be seen in figure 2, the arm 33 can present a pad 35 which, due to the elastic effect of the projection 34, presses against the cord 15 wound around the reel 14. One arm 36 of the lever 31, opposite the arm 33 with respect to the pin 32, acts as a trigger by protruding from the casing 12 through a respective opening 37 allowing it to be activated from the outside.
The projection 34 of the arm 33 can present portions with different coefficients of elasticity in order to ensure a pressing action which gradually increases in relation to the length of the cord 15 wound around the reel 14. In this way the reel 14 is braked with a shock- absorbing effect allowing rewinding control by means of the external trigger 36.
The pad 35 also ensures that the cord 15 is not completely rewound onto the reel 14 so that a minimum portion of the cord 15 is left protruding from the leash. The pad 35 can immediately block or release the rotation of the reel 14 again by means of direct control from the outside by activating the trigger 36. With reference to figure 3, it can be seen that the arm 33 of the lever 31 can be equipped, as an alternative to the pad 35, with a roller 38 designed to reduce the abrasion of the cord 15 due to the friction of the pad 35. As can be seen in figure 4, the projection 34 can be curved in the same direction as the rotation of the reel 14 for the unwinding of the cord 15, thus considerably reducing the wear of the cord 15 with a slightly lesser braking action.
The lever 31 can be part of a more complex mechanism designed to guarantee simultaneous blocking and releasing of the cord 15 in different positions as well as controlled end-of-travel braking with different decelerations that can be controlled by the user.
The leash 10 can comprise a device, inside the casing 12, to detect the extent to which the cord 15 is wound onto the reel 14 and an indicator which informs the user of the immediate condition of use.
Thanks to the controlled automatic braking device 11, the user runs no risk of the rapid return of the cord 15 with consequent "whiplash" of the spring clip attached to its end.
The casing and the various 'parts of the leash 10 can be made from composite plastic material and/or metal.
The invention described above refers to a preferred embodiment. It is however clear that the invention is susceptible to numerous variations within the framework of technical equivalents.
By way of example, according to a further form of embodiment not shown in the figures, the device comprises a clamp guided inside an appropriate guide in the casing of the leash. According to this form of embodiment, one end of the clamp comprises an arm, which may be hinged to this end, equipped with a pad or roller designed to interact with the cord wound on the reel. The other end of the clamp protrudes from the casing of the leash and is equipped with a manually activated slider. This clamp is permanently stimulated by an appropriate spring, which may be an integral part of the clamp or fixed to it, in such a way that the pad or roller comes into contact with the cord. According to all the forms of embodiment of this invention, the clamp or the lever can be equipped with a coupling retainer which makes it possible to exclude the activation of the braking device, which otherwise acts automatically and independently of the user's manual action.
