Description

[Detailed description of the invention] animal jaw opening device 〔Technical field〕 The present invention is for the treatment of the oral cavity or throat, especially teeth, of animals, especially ungulates such as horses. In an animal jaw opening device, a thong or similar is used to connect two mutually pivotal parts. A fitted yoke is attached to the animal's head, and the device includes a first the animal's anterior teeth from one temporomandibular joint, the means being pivoted to each other at the temporomandibular joint area; The present invention relates to a device that extends through the temporomandibular joint to the other temporomandibular joint.

[Background technology]

Prior art devices for opening a horse's mouth, such as opening bits, are made up of multiple parts. They are typically multiple structures, unreliable and expensive. Furthermore, these prior art Applying the device to animals was not easy.

If the animal does not land and is difficult to handle, the more difficult it becomes to handle it. Of course. It is clear that there is a serious danger when using prior art opening screws, etc. It became a thing. In other words, these devices can be used to treat animals' teeth, etc. It causes injury to both people, e.g. veterinarians, and their animals. -For example, animals In recent years, in order to improve the nutritional content of the feed, the sharp edges of the teeth have been improved. Filing is common practice in trotting, horse racing and show jumping. became 0 Thus, reliable and easy-to-use oral brace materials are highly needed in the industry. It is said that

[Object of the present invention]

The basic problem of the present invention is therefore to provide a simple and reliable oral Providing support material.

〔Method〕

According to the invention, in the device mentioned in the introduction, the angle lever is arranged at least on one side. It is pivoted to the yoke at a point between the animal's temporomandibular joint and the front teeth, and the angle When pivoting the second angle arm of the lever, the first angle arm moves to the second yoke. by being configured to pivot from the first yoke to open the animal's jaw. The following tasks will be achieved.

〔advantage〕

As a result of the invention, a very simple device is provided for opening the mouth of a horse, for example. It will be done. First, this device is extremely easy to apply to the horse's head. For some reason , this device is treated in much the same way as a bridle or kei roku, so the horse knows that the device is This is because it is considered natural to be placed on the head. For example, in the case of light roku, the horse Even with the device according to the invention, where it is natural for the horse to open his mouth and receive the footboard, The horse opens its mouth, receives the plate between its front teeth, and then attaches the leather strap around the horse's neck. Wrap it around your ears and behind your ears. When the thong is tightened, open the upper and lower yokes is a very simple operation, and in this way, for example, a veterinarian can easily remove a horse's teeth. can be treated or other treatments of the animal's oral cavity can be carried out . The device of the present invention does not cause any harm to animals and is inconvenient for the person using it. Not. The lever mechanism is configured to prevent the horse from closing its mouth unexpectedly. This is desirable.

The device according to the invention can also be adapted very easily to the desired opening degree.

[Brief explanation of the drawing]

The nature of the invention and its aspects will become more apparent from the description of the accompanying drawings below.

In the attached figure, 1 is a side view of an embodiment of the device according to the invention; FIG. 2 is a plan view of the device of FIG. 1; Also, although Figure 3 is similar to Figure 1, the various parts of the device are shown in different positions. This is a diagram.

[Description of preferred embodiments]

Embodiment B of the present invention shown in the attached drawings essentially consists of an upper yoke 1 and a lower yoke 2. . The free end of the lower yoke 2 is provided with a thong buckle 3, which buckle 3 is attached to the yoke 2. It can be pivoted to. The leather string 4 is passed through the knot 3 and tied around the horse's neck. It is passed on to the department. The thong 4 passes over one or more conventional fasteners 5 to the right. desired The leather thong 4 must be equipped with a hitai band to secure it to the horse's head. Can be done.

The free end of the upper yoke 1 is pivoted to the free end of the lower yoke 2 by bolts 6.7. It will be worn. Bolts 6 and 7 can be of any type, but only one end of them is threaded. with ridges and completely smooth in the area of contact with the inner wall of the hole at the end of the yoke 1.2. It seems most appropriate to do so.

The upper yoke 1 is provided with a filler plate 8 at its front arcuate end, and this filler plate 8 has similar teeth. , with a sheath 9 of some kind of material, for example a suitable plastic. It is clear from Figure 1 that As shown, the filler plate 8 is arranged along one edge of the yoke 1, so the yoke 1 itself and the filler plate 8, a lateral surface, that is, a contact surface is formed, and this contact surface The coating 10 is made of some kind of material, for example a suitable plastic material, similar to a tooth. We are prepared.

Like the upper yoke 1, the lower yoke 2 is provided with a filler plate 11. 8 and a similar covering 12. Like the filler plate 8, the filler plate 11 has a contact surface. The contact surface is covered with a suitable coating 13.

A connecting arm 15 is pivotally attached to one side of the yoke 1 by a bolt 14, and the yoke A connecting arm 16 is pivotally attached to the other extension of the arc 1 by a bolt 17.

The free ends of link arms 15 and 16 are connected by respective poles 18 and 19. The angle levers 22 and 23 are pivoted to the free ends of the angle lures 420 and 21. ing. These angle levers 22 and 23 are connected to the lower yoke 2 by bolts (25 ) is pivotally connected by K.

The long arms of the angle levers 23, 24 are interconnected by a cross member 26. . Bolts 14, 17, 18, 19, 25 may have the same structure as bolt 6.7. can. The angle lever can be of one-piece construction and the angle lever can be The arms 20 and 21 are bent in accordance with the shape of the yoke so that they are placed on both sides of the yoke 2. I'm getting lost.

When the angle lever 24 is pivoted counterclockwise in FIG. 3, the upper yoke 1 is pivoted to the open position shown, and the upper yoke 1 is pivoted to the open position shown. The filler plate 8 is spaced a certain distance from the filler plate 11. When the device is used on a horse, the horse is When plates 8 and 11 are bitten, the horse's mouth is opened and held open as shown in FIG.

As seen in FIG. 3, bolts 18 and 19 connect bolt 14 and bolt 25. It pivots beyond the line of imagination. This allows the horse to move yokes 1 and 2 to the position shown in Figure 1. I can't go back. In order for the horse to be able to close its mouth, bolt 18 must be The position must be opposite to that shown in Figure 3 with respect to the imaginary line. Diagram of each part of the device 3, a third yoke 27 is disposed on the yoke 2, and this yoke 27 is provided with a lock 28. This lock 28 is fixed to one end of a bolt 29. There is. The end of the bolt 29 is fixed in the lock 28 and inserted into the hole in the yoke 27. It is inserted. In order to spring the lock 28 to the position shown, the yoke 27 and the bolt A compression spring 30 is arranged between the head of 29 and the head of 29.

If you want to release the lock 28 from the position shown in Figure 3, remove the head of the bolt 290 from the spring 30. When the cross member 26 is pushed in the direction of the yoke 27 with resistance, the cross member 26 is released from the lock 28. and can be pivoted to the position of FIG. Of course, Yoke 27 is essential. Although it is not an element and the lock 28 is not required, as a result of the test, the yoke 27 will also be installed soon. to provide suitable support during animal age or oral cavity treatment. It became clear that it would form a body.

The yoke 1.2, the angle levers 23, 24 and the articulating arm 15.16 are preferably can be made from stainless steel strip, but other materials are of course possible. .
