This invention relates to a dog collar-leash combination with a collar and with a leash in a housing, with a rolling and unrolling mechanism, wherein the leash in the housing can be unwound against a spring force and where the outer end of the leash has a handle. In the following it will be clarified that this is a collar-leash combination for animals, especially dogs, but not limited to dogs. The term “dog collar-leash combination” is therefore intended to extend to other animals that are led on collars with a leash, such as for example cats or the like.
Retractable dog leashes on a dog collar are known in different embodiments. DE 27 042 28 A1 describes, for example, a self-retractable dog leash, which is retractable into a housing via a steel spring. It is also intended that the pulled-out dog leash can be locked and unlocked by a separate button.
Furthermore, from DE 77 36 528 U1 a dog collar is known onto which a housing made of plastic or metal is attached, wherein a dog leash is housed self-retractable via a spiral tension spring. Similar embodiments are shown in DE 80 31 227 U1 or DE 91 12 680 U1.
U.S. Pat. No. 7,174,857 B2 describes an animal collar with an integrated leash that can be pulled out of a housing.
DE 10 2004 038 935 A1 shows a slightly different embodiment, in which a dog collar has an integrated dog leash wrapped around the dog collar.
DE 100 12 699 C1 shows another variant of a dog collar having an inwardly directed inner band and an outer band situated on the outside, wherein the outer band is elastically extensible or extensible against a restoring force. Thus, if needed, a strap is pulled out of the collar from two sides, which allows the dog to be led.
The disadvantage, however, is that the known dog collars with an integrated, retractable dog leash must first be put on around the neck of the animal in the usual way with an adjusted, fixed neck width. Furthermore, a contracting function is not provided in the known dog leashes.
The object of the invention is therefore to form the rolling-up mechanism of the retractable leash which is located on the collar in such a way that an easy putting-on of the collar and a retraction function are integrated.
This problem is solved with a dog collar-leash combination according to claim 1. Since the collar has two free ends, it is not fixed around the neck of the animal, but can be further opened by pulling of the leash from the housing. This is possible because at the first end there is a housing for the leash and thus the leash is stored and at the second end a loop is provided through which the handle of the leash is fed. In this combination, the leash can be grabbed at the handle by a user and pulled out of the housing to the maximum length. In this case, the dog collar-leash combination acts like a conventional collar to which a leash is attached, but here there is no firm connection between the two ends of the collar, so there is no solid neck loop, but a variable loop.
If the two ends of the collar have mutual support elements, then when pulling on the leash, whether from the animal or the pet handler, as the two ends of the collar are moved towards each other only so far until the support elements of the two ends support each other. This ensures that the collar is not pulled tighter and thus the animal is not affected adversely or even injured.
In a further embodiment, the collar is adjustable in its length. This allows the collar to be adjusted to the circumference of the neck of the animal. Since the collar can expand in this design against the spring force of the retracting mechanism, the collar can also be set a little tighter on the animal, so when using the dog collar-leash combination with a strong pull on the leash, a slight strangling function by the contraction of the collar is reached at its minimum circumferential length. In normal situations the collar would stay closed merely with a light spring tension around the neck of the animal.
To further improve the comfort of the dog collar-leash combination for the animal, the spring force for retracting the leash can be made adjustable. This makes it possible to adjust the spring force so that the collar closes around the neck of the animal with sufficient astringent effect without overly adversely affecting the animal.
By providing a locking mechanism on the rolling and unrolling mechanism, with which the leash can be locked in any particular length, the leash can be locked in any extended position. When the leash is locked in the fully rolled up condition, a conventional dog collar in a rigid, closed form that attaches itself to the neck of the animal exists. For example, if the leash is completely unrolled and then locked, the result is a typical dog leash situation in which the dog handler can easily lead the animal. The only difference to previous dog collars is that the collar simply forms an expandable loop around the neck, as already described above.
When the two ends of the collar have coupling means for connecting the two ends, the collar can be converted through the coupling means, by coupling the two ends, into a conventional collar fixedly placed around the animal's neck. Preferably, the coupling means consist of a snap hook at the first end and a loop at the second end of the collar. In this case, the snap hook is hooked into the loop at the other end of the collar so that the collar can no longer be widened by the leash passing through the loop.
A reliable rolling and unrolling mechanism for the leash is provided in the housing in that the rolling and unrolling mechanism in the housing has a helical retracting spring and a rotatable supported cartridge for the rollable and unrollable leash.
In order to provide a flexible, easily retractable and at the same time stable leash, the leash is formed of a braided rope, preferably nylon. If the collar is formed from a flat ribbon textile fabric, preferably nylon, a collar for the animal that is well-wearable and stable is indicated.
If a fastener is provided at the outer end of the leash or on the handle to fix this on the collar, it is prevented that the outer end of the leash, the handle or the loop arranged at the outer end of the leash of this dog collar-leash combination dangles down and the dog with this dangling leash gets caught on any objects. For the user, the access to the outer leash end or handle or handle loop is always guaranteed. Preferably, the fastening means is a magnetic coupling.
An embodiment of the invention is described below in detail with reference to the accompanying drawings.
There is shown in:
The two ends 11, 12 have matching support elements 14, so when pulling the two ends 11, 12, these support elements 14 abut against each other, as shown in
In the housing 20 for the leash 2 there is a rolling and unrolling mechanism 21 fitted with a helical spring, not shown, and a rotatable cartridge for the rolled up leash 2. The free end of the leash 2 is equipped with a grip 22, which on the one hand serves for comfortable holding of the leash 2, and on the other hand prevents that the leash 2 can completely slip through the loop 13. The leash 2 consists of a braided core/cladding rope 24 made of nylon threads.
The operating principle of the dog collar-leash combination is described below with reference to the two embodiments illustrated in
In the basic position of the dog collar-leash combination the two ends 11, 12 of the collar 1 lie with their supporting elements 14 against each other and the leash 2 runs from the housing 20 through the loop 13, with the grip 22 of the leash 2 situated directly at the loop 13. The spring tension of the rolling and unrolling mechanism 21 causes a load to be applied to the two ends 11, 12 or the support elements 14, wherein the collar 1 is expandable against this spring retracting force, in that the leash 2 is pulled out of the housing 20. In this situation the dog collar-leash combination is shown in
The dog handler can thus grab the collar 1 on both sides of the ends 11, 12 and can open it against the spring restoring force of the leash 2 (as shown in
In the second embodiment shown in
If the coupling element 15 is unlocked via the snap hook 16, the dog collar-leash combination according to
Advantageously, the dog collar-leash combination according to this application can easily be put on by stretching and pulling over the head of the animal. With his collar, the dog always wears the leash 2 in the housing 20 with him. By grasping the handle 2, the dog handler can immediately unroll the leash 2 for a comfortable leading of the dog. Due to the additional functions of the locking mechanism 23, different lengths of dog leash 2 can be fastened, or even the position with the grip 22 adjacent at the loop 13 can be locked where practically a conventional collar (which is not expandable against the restoring force of the leash) is provided. By loosening the locking mechanism 23 the special function is again immediately activated. A rigid function of the collar 1 can be created with further development through the coupling element 15, even though the leash 2 is pulled out against the spring force. In a further embodiment the locking mechanism 23 of the leash 2 can bring about that the known functions of a fixed dog collar and a fixed dog leash are present.
