This application claims priority to Hungarian Patent Application registration number 7014/14, filed on Feb. 25, 2014 and incorporated herewith by reference in its entirety.
The invention relates to a quick release chest harness with an elastic chest strap, developed for four-legged mammals, comprising a back strap, a leash ring fixed on it for attaching a leash, a belly strap equipped with a quick release buckle, and a chest strap running between the chest bone and the throat area. The chest strap is attached at the connection of the back strap and the belly strap on both sides of the harness, and furthermore there is a connecting element between the chest strap and the back strap, connecting them at an angle. The chest strap is elastic, capable of stretching over at least one given section and to a given extent, reducing the load on the shoulders of the dog or any other mammal kept as a pet. With the belly strap equipped with a quick release buckle, the harness is practical for everyday use, for example for securing in a car.
The chest harnesses disclosed in the prior art, with the relegation of pulling or driving horses to be background, were developed primarily for dogs, as they are an ideal solution for leading a dog on a leash, holding it back, and for distributing the pressure caused by the acting forces.
The chest harnesses found in the prior art are dog harnesses comprising leather and/or textile straps, padded on the back part, chest part and belly part of the dog in a fixed, or sometimes in a releasable manner. These dog chest harnesses are also called “saddle-harnesses”, when the padded part resting on the back of the dog is covering it like a saddle. The purpose of padding is to distribute the pressure, to stabilize the straps, and to allow the attachment, display of additional equipment (e.g. bag, light, GPS or camera devices) and/or graphic elements, high visibility colours, labels on the padding itself, or on the cover thereof. The straps covering the belly part and the chest bone part (the chest strap and the belly strap) are subjected to increased stress when the dog is lead on a leash, or during training and police work. On dog chest harnesses according to the prior art these straps are fixed together, incapable of stretching (form-stable) to any substantial extent. They are made by weaving processes (by interlacing warp yarns and weft yarns) used regularly in the textile industry, usually from synthetic (PE, PP, PA) fibres. These straps retain their length under load. Their stretchability, elasticity is far below that of rubber, silicone or elastomer materials, and their stretching leads to a permanent reduction in load-bearing capacity, or breaking. In fact, especially the bones of developing young dogs need to be spared form strong impacts. This includes even the load resulting form the daily walk on a leash. The padding of the chest strap and/or the belly strap is only a partial solution, because a sudden force, a shock-like load on the straps is not sufficiently reduced by the padding material.
The chest straps of dog harnesses preferably consist of at least two parts, but there are also undivided, non-adjustable chest straps made of one strap connecting the two sides of the harness and also the two ends of the back strap, in the continuation thereof.
The most common chest strap design for dog harnesses, divided into two main parts, adjustable by a hook-and-loop fastener by threading through a fastener/slide adjuster, is a Hungarian development from 1997, and was introduced into regular use first for Austrian, then for German service dog units under the name “K9-Powerharness” (DE302009060989). As the name of the device already suggests, it was designed for high loads occurring especially in the case of dogs. The success of the dog harness lies in being practical, quick to put on and take off.
The chest strap, attached to the connection point of the back strap and/or the belly strap, in the continuation thereof, on one side of the dog harness ends in a cut edge, while on the other side it preferably ends in an oval fastener/slide adjuster. The former section of the chest strap gets in a position suitable for use by threading through this fastener/slide adjuster and closing on itself. Thus in this case the chest strap is divided into two parts, as there is, one section on one side of the dog harness, extending from an oval ring-shaped fastener/slide adjuster to the connection point of the belly strap and/or back strap (chest strap part holding the fastener/slide adjuster), while there is another section on the other side of the dog harness, closing on itself, threaded through the fastener/slide adjuster during use (adjustable-length chest strap part). This chest strap section extends from the cut edge of the adjustable-length chest strap part, equipped with a hook-and-loop fastener, to the connection point of the adjustable-length chest strap part and the back strap and/or the belly strap. In the prior art pressure distributors for chest straps are attached to the hook-and-loop fastener of the latter, the adjustable-length chest strap part of the chest strap closing on itself, and/or to the chest strap itself, by threading onto it.
Utility model No. U10 00003, disclosing a chest pad made of a foam material, describes a pressure distributor that is not only threaded onto the chest strap of a chest harness, but is also attached to the hook-and-loop fastener thereof. The chest pad makes it much easier for the dog to tolerate lifting e.g. by the handle fixed on the harness. In the event of a sudden load in the direction of movement, the chest of the dog is supported by the whole width of the surface of the chest pad, but it will not stretch to a given extent. Therefore its load-absorbing capacity is low.
Utility model No. U11 00245, disclosing a so called “I”-strap, also describes the padding of the chest, or the chest strap of the dog harness, as well as the dog collar. This pressure distribution device is mounted on the chest strap in a releasable manner, perpendicularly to it, it connects the chest strap and the belly strap of the harness, and at the same time it can be connected to the collar as well. The significance of the device is that by fixing three points together, the use of the harness becomes safer for example for service/assault dogs, as it prevents the chest strap of the dog harness from sliding down towards the forelegs of the dog during vigorous movement. However, it does not affect to a large extent the load on the chest part and the shoulder joints. Nevertheless, the significance of the device is indisputable, as the “I”-strap was the first elastic pressure distribution element mountable on dog chest harnesses in a releasable manner, since it is connected to the collar by means of a rubber ring. The limitation of stretching was not implemented for the elastic portion connected to the dog collar. The development and spread of pressure distribution devices mountable on dog chest harnesses among hobby dog owners clearly proves that there is a demand for such products, and in fact their use solves a major problem. In the case of pulling harnesses made for horses, there are no known elastic pressure distribution elements, operated/fastened by means of a hook-and-loop fastener and rubber solution.
The disadvantage of all three devices, however, is that for using them the hook-and-loop fasteners need to be opened/closed, and the chest strap also needs to be partially opened. The dog chest harness known in the prior art, due to its chest strap incapable of elastic stretching, can not be used for mammals having a chest with a genetically different anatomy from that of dogs. Harnesses can/should be used for cats and even for rabbits kept as a pet, as the use of a collar can choke the animal. For safely securing the harness, the animal should be prevented from jumping, stepping over the chest strap with its forelegs. This risk exists not only in the case of cats and rabbits, but some agile dog breeds as well. The harnesses used in the prior art for such animals are not chest harnesses, therefore they are more complicated to put on and take off, even if quick release buckles are used as fixing elements.
Patent No. US2007/0034164A1 discloses a development where on the chest part of an elastic harness, to be used only for dogs, the continuity of the load-bearing (non-elastic) straps is interrupted by an elastic insert. The biggest disadvantage of the development is that no element covering the elastic elements, limiting their stretching is provided for the dog harness, to perform a load-bearing function, and to limit the stretching of the elastic portion. Therefore the permanent, deforming stretching of the elastic portion is inevitable, and its breaking can be avoided only by using oversized, excessively thick elastic elements.
The aim of the invention is to improve the chest harness suitable for securing four-legged mammals, primarily dogs e.g. in a car or during police work, within that to develop an elastic chest strap and/or a chest strap capable of elastic stretching over a given section, protecting the shoulder joints. Another aim is to eliminate the disadvantages of the prior art, to increase the pressure distribution effect without any special adjustment and/or mounting work on the part of the user. Still another aim is to make the chest harness also suitable for other mammals kept as a pet, with a different chest anatomy from that of dogs, by making the elastic chest strap always close fitting during movement.
The invention is based on the recognition that e.g. in the event of a car accident, or the special carrying, descending of service dogs, such forces act on the chest of the animal that the pressure distributors, elastic harnesses disclosed in the prior art can not sufficiently compensate, or in some cases endure without deformation. An element capable of limited stretching over a given section can be implemented for the chest strap of the chest harness, and is suitable for significantly reducing the risk of injury caused by sudden loads on the chest of the animal during use. Due to the low load-bearing capacity of the elastic portion, the extent of stretching of the chest strap should be limited by a separate element.
It is further recognized that the quick release chest harness is very easy to put on and take off in the case of other mammals as well, but due to the fixed chest strap incapable of elastic stretching, the animal can jump over it with its forelegs and get loose from the harness, or get entangled in it. This risk exists especially in the case of animal species with a chest anatomy significantly different from that of dogs (rabbits, cats). If the stretching of the chest strap is not properly maximized, then dogs can also get loose from the harness. If a separate element does not take over the load from the elastic portion of the chest strap, then it will wear out prematurely, and will pose a risk of injury to the dog.
Thus the invention relates to a chest harness with an elastic chest strap, developed for four-legged mammals, comprising at least one back strap, on the back strap at least one leash ring, a chest strap crossing the back strap, surrounding the chest of the animal and connecting the two shoulder joints, and furthermore at least one adjustable-length, openable belly strap in the continuation of the crossing of the back strap and chest strap, surrounding the chest of the animal from below, and furthermore at least one connecting element, closing an angle of less then 85 degrees with the chest strap, connecting the chest strap to the back strap in a fix manner in the direction of the leash ring.
The essence of the development is that the chest strap of the chest harness with an elastic chest strap has at least one elastic portion, the maximum stretching of which is determined by an element limiting the stretching of the elastic portion.
The element limiting the stretching of the elastic portion is most preferably a strap.
The element limiting the stretching of the elastic portion is most preferably formed from the chest strap part holding the fastener/adjuster ring, in the continuation thereof.
The elastic portion and the element limiting the stretching of the elastic portion preferably pass through the fastener/adjuster ring.
The elastic portion is preferably a strap containing rubber threads.
The chest harness with an elastic chest strap according to the invention is shown in the following figures:

In
The chest harness with an elastic chest strap, equipped with an element limiting the stretching of the elastic portion, preferably implemented as a bulging part of the chest strap, ensures a safe and convenient way for leading on a leash and securing dogs and some other four-legged mammals. It is perfectly suitable for absorbing sudden, shock-like forces experienced e.g. in a car accident, for protecting the affected joints. Due to the element limiting the stretching of the elastic portion, the elastic portion becomes capable of tolerating the acting forces without deformation in the long-term, and of giving reliable tensile testing results.
While the invention has been described with reference to an exemplary embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
