DESCRIPTION

TRACKING DEVICE FOR DOG TRAINING ON THE BICYCLE

When training dogs on a bike, it is important to attach the dog to the bike in such a way that optimal safety is guaranteed, taking into account the dog's individual running and pulling characteristics.

The safety aspects in detail include the possibility of preventing the dog-bike connecting leash from getting caught in or on a bicycle part; a possibility of dampening sudden jerks and irregular running of the dog; choosing the optimal tethering point on the bicycle while avoiding unfavourable leverage effects for the rider.

A commercially available tethering device (Pat. No. 0270629 Bl) allows the dog to be tied to the end of a spring that is attached to the side of the bicycle frame. This prevents the leash from getting tangled in the bicycle frame and the dog's jerks are cushioned by the spring. The spring must be designed to be strong enough to withstand the dog's entire pulling force. This inevitably results in a certain stiffness of the spring.

With the tethering device described above, dogs that run alongside the bike and do not pull extremely hard can be safely moved. A dog that pulls hard, however, should be tied at the level of the bike frame, preferably at the front part of the frame, to avoid strong lateral leverage. However, if the dog's pulling power decreases, there is a risk that the leash could get caught on the front wheel or its axle.

Attaching the pull line to the end of a spring mounted on the front bicycle frame has the disadvantage that the spring's stiffness requires a fairly large lever arm on the bicycle frame. If the dog breaks out across the direction of travel, it is therefore difficult to counter-steer to correct the course. A weaker design of the spring would, however, mean that it would pass through to the front wheel and the dog's pulling force would no longer be able to bear the load.

The invention specified in claim 1 is based on the problem of creating a pulling device that has the functions

- Absorption of the dog's pulling force (for direct transfer to the bicycle frame),

- guiding the leash (to prevent it from getting caught on a bicycle part and without significantly restricting the lateral movement of the leash), and

- Shock absorption (to cushion the dog's running irregularities)

fulfilled in such a way that they are independent of each other.

This problem is solved with the features listed in claim 1. The pulling device described in claim 1 comprises a fastening device 1 for mounting on the bicycle frame, to which a bracket 3 that can be pivoted laterally to the plane of the bicycle frame and at least one ring, hook or eyelet 5 for hooking the

Leash are arranged, the bracket 3 having an eyelet 4 or a downward U-shaped bend at its end.

The dog's leash is threaded through the eyelet 4 at the end of the pivoting bracket. The end of the leash is attached - usually with a snap hook - to the ring, hook or the eyelet 5, which is either located directly on the fastening device or on the connecting rail 2.

The invention ensures that the dog's leash cannot get caught on or in a bicycle part by hanging down. The pulling force of the dog acts directly on the bicycle frame. The pivoting bracket 3 only has to bear part of the weight of the leash, which enables a light and cost-effective construction. The leash can be pivoted sideways so that if the dog runs off to the side, the bicycle is not encouraged to tip over by a lever arm protruding forward.

The shock absorption can be achieved individually and inexpensively using commercially available shock absorber leashes that contain an integrated rubber cord. This allows the shock absorbing element to be specifically adapted to the running and pulling characteristics of the dog.

The easy lateral pivoting of the bracket 3, which fixes the line at a certain height, is achieved by the features described in claim 2. The combination of an inflexible arm 6, at the forward-projecting end of which there is an eyelet 4 for threading the line, with a rotary, torsion or spring element 7,13, which is arranged as close as possible to the bicycle frame, on the one hand prevents the bracket 3 from sagging on the front wheel, but on the other hand allows easy mobility under the influence of a change in the direction of the pull line.

An advantageous embodiment of the invention is given in claim 3. The further development according to claim 3 enables the bracket 3 to be removed after the training ride with the dog has ended by loosening a screw connection.

In the design of the pulling device described in claim 4, the attachment of the leash 11 is made significantly easier, since it is no longer necessary to thread it through the eyelet 4 of the pivoting arm. In this case, the pulling leash is divided into two parts, with one part 9 being stationary on the pulling device and containing a tie ring for attaching the dog's pulling leash, which protrudes from the eyelet 4. This stationary part of the leash can also consist of an elastic rope, thus directly taking over the function of the shock absorber.

The design described in claim 5 provides a telescopic arm instead of the inflexible arm 6. In addition to shipping advantages, this also results in practical advantages for the user, since the arrangement can simply be pushed together after the training trip with the dog and thus no longer causes any visual disturbance.

Embodiments of the invention are explained with reference to Figures 1 to 4. They show:

Fig. 2 a pulling device in plan view

Figures 1 and 2 show a towing device with fastening device 1, connecting bracket 2 to the front, swiveling bracket 3 and tethering eyelet 5. The fastening device 1 consists of two pipe clamps, to the upper half clamps of which the connecting bracket 2 is welded. Here the towing device is mounted on the front frame part. The bracket 3 protrudes forward in the direction of travel. It consists of a rigid arm 6 and a rotating head 7, which is attached to the connecting bracket 2. The rotating head 7 consists of a torsion element, in this case a Chimmi cylinder, which has a waist-shaped constriction in its middle to enable the bracket to be easily swiveled sideways. The pulling line 11 is threaded through the eyelet 4 at the front end of the bracket and hooked with a snap hook into the ring 5, which is screwed through the connecting arm 2 into the lower part of the gximmi cylinder.

Figures 3 and 4 show a pulling device in which the connecting bracket 2 symmetrically surrounds the cantilever cable brake cable 12, which is standard on many bicycles, on both sides. A cube 8 is welded onto the connecting bracket 2, which contains two holes perpendicular to each other to accommodate the pivoting bracket 3. One hole is used to accommodate the bracket, pointing in the direction of travel. By inserting the bracket into the other hole, offset by 90°, the dogs running alongside the bicycle, which do not pull very strongly, are taken into account. The bracket 3 is fixed in position in one of the holes by screwing in a screw from above and can be easily removed again by loosening this screw after the training ride has ended. A rope 9 is looped into the connecting bracket 2 to the bicycle frame, the end of which protrudes through the bracket eyelet 4 and the end of which contains a ring for receiving the pull cord 1L. The pivoting bracket consists of a round rod and a spring element 13, which is arranged as close as possible to the fastening bracket 2.
