Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an animal ear tagging tool for tagging animals, such as identification ear tags.

Animal ear tagging tools are known which have a construction consisting of a first and a second lever connected to each other by a pivoting means and which can be pivoted about a pivot axis. First and second jaws are actuated by first and second levers and each include retaining means for retaining a portion of the animal's ear tag. 1st
A return device, for example a spring, is provided for returning the second jaw from the closed position to the open position. Such animal ear tagging tools are described, for example, in Japanese Patent No. 829,633 and US Pat. No. 4,120,303.

When using an animal ear tagging tool, the component parts of the ear tag (which may be, for example, ear tags of the type disclosed in the specification of applicant's Japanese Patent No. 829634) are pressed against each other. They are attached to the first and second clamps so as to be arranged facing each other. then,
The animal's ear is placed in the space between the first and second jaws such that the lowest portion of the ear is located near the throat of the animal ear tagging tool.

Moving the first and second jaws to the closed position brings together the female and male portions of the eartag, thus attaching the eartag to the animal's ear.

In the closed position, the first and second jaws are closest to each other in the vicinity of the pivoting means between the first and second levers (i.e. in the throat of the animal ear tagging tool). Therefore, the animal's ear may be caught between the first and second clip parts and may be injured. To overcome this problem, the throat of the animal ear tagging tool may be deepened by extending the first and second jaws so that the retaining means is further away from the pivoting means. can. However, this is not a practical solution to the problem since it reduces the lever ratio and makes ear tag attachment more difficult.

The present invention comprises a pivoting means having a cavity in the center, which cavity remains open during the movement of the first and second jaws between the open and closed positions. This difficult problem is overcome by providing an animal ear tagging tool characterized in that, in the closed position and the closed position, the animal ear tag is connected to the space between the first and second jaws. It is.

By using a centrally spaced pivot that communicates with the space between the first and second jaws, the throat of the animal ear tagging tool of the present invention can be effectively moved that far away from the retaining means. Spacing is maintained. However, since the axis of pivoting motion does not change, the effective lever ratio does not change. Therefore, the animal's ear can be accommodated in the throat of the animal ear tagging tool without being pinched between the first and second jaws in the so-called closed position.

In order to describe the invention in detail, reference is made to the accompanying drawings. According to a preferred form of the invention, the animal ear tagging tool consists essentially of two halves B' and B'' (which may have a construction of cast alloy, for example), each half B' and B'' being , consisting of a lever in the shape of an integrated handle, a main body part, and a clamp part. These two halves B' and B'' are held together by being joined together by suitable means.

A variety of methods can be used to interconnect halves B' and B'' of the animal ear tagging tool, and the following description relates to one preferred format.
FIG. 4 shows one half B' of the animal ear tagging tool, which half consists of a lever 10 in the form of a handle, a body part 11 and a jaw part 12. The other half B'' of the animal ear tagging tool is shown in FIG. , each having an annular shape and substantially radially located openings 17 and 18 extending into internal circular openings 19 and 20, respectively.
have.

With reference to FIGS. 5 and 7, it is observed that the body portions 11 and 15 have a smaller cross-sectional thickness than the lever and jaw portions, respectively. Main body part 1
1 and 15 are each located on one side of the longitudinal axis of symmetry of the half of the animal ear tagging tool. To assemble the animal ear tagging tool, the two halves B' and B'' are assembled together so that the flat surfaces 11a and 15a of the bodies 11 and 15 are in face-to-face contact (see Figure 2). To keep the halves B' and B'' together, a fastening bush 24, illustrated in detail in FIGS. 8 and 9, is used.

Bushing 24 may be constructed from any suitable material, such as a resilient plastic material (eg, acetal).

The bushing 24 is comprised of a pair of opposite and parallel flanges 25 and 26, each preferably in the form of a slightly concave dish, as seen in FIG. also have The flanges 25 and 26 are radially arranged to form open ended slots 27. Flange 25 and flange 26 are connected by a curved wall 28 having an arcuate cross-sectional shape similar to the shape of the arcuate inner end of slot 27;
Thereby, the wall 28 is located around the curved inner surface 29 of the slot 27. A pair of diagonally opposed outer straight edges of the slot 27 are provided with inwardly projecting walls 30 forming a cover plate in the assembled animal ear tagging tool.

When halves B' and B'' of the animal ear tagging tool are assembled together, the bush 24 is passed through the aligned openings 17 and 18 and aligned with the body parts 11 and 15. It is inserted into the internal circular openings 19 and 20 and is force-fitted.Thus, the wall 2 of the bushing 24
8 connects the flanges 25 and 26 to the main body parts 11 and 1.
openings 19 and 2 that are aligned in a straight line while being placed in face-to-face contact with the outermost surface of
placed in 0. A surface where the lever 10 and the clamping part 12 of half B' face the main body part 15 of half B'',
And the lever 14 and the clamping part 16 of half B'' are half
The faces of B' facing the body portion 15 form curved surfaces 11b and 15b, respectively, and lie at right angles to the flat surfaces 11a and 15a.
These curved surfaces 11b and 15b
As clearly shown in the figures, when the bodies are assembled they contact curved surfaces 15c and 11c of bodies 11 and 15, respectively. The pivoting movement about the pivot axis is thus carried out in conjunction with the fastener bush 24 which holds the two halves of the animal ear tagging tool in interlocking relationship.

The body parts 11 and 15 each have a flat surface 11
Concentric circular grooves 21 are formed in each of a and 15a. A telescoping bearing 22 having approximately half the length of the groove 21 is inserted, and a pin 2 is inserted at one end of the groove 21.
It can be stopped by 3. Therefore surfaces 11a and 15
When a is in face-to-face contact, the telescoping bearing 22 in the groove 21 is engaged with the portion unobstructed by the telescoping bearing in the opposing groove. Preferably, the telescoping bearing is made of plastic material. Moreover, the mutual engagement between these grooves 21 of these fitting bearings 22 is as follows.
A bearing surface is formed to prevent sticking between the flat surfaces 11a and 15a.

The levers 10 and 14 each have a spring 31
A plug 31 is formed which determines the position of the free end of a.
This spring 31a is normally secured between the upper ends of levers 10 and 14 to force the two levers apart, as shown in FIG. The ends of the plug 31 touch each other when the animal ear tag attachment tool is closed.
Provide a reliable means of stopping.

A locking catch 32 is used to lock the animal ear tag tool in the closed position shown in FIG.
is provided. The locking catch 32 consists of a catch 33 rotatably mounted on the pin 34 within the boundaries of the recess 35 . The catch 33 is biased toward the unlocked position shown in FIG. 3 by a spring 36. When the animal ear tagging tool is placed in the closed position (FIG. 1), the catch 33 is pushed into the position shown so that the most extreme inner edge 32a of the catch 33 is pressed against the body. 15 (see FIG. 6) and wedges therein for the levers 10 and 14, which tend to move apart under the influence of the spring 31a. To open the animal ear tag tool, pressure is applied to levers 10 and 14 to overcome the force exerted by spring 31a, thus causing spring 36 to return locking latch 32 to the unlocked position. It can be so.

The animal ear tagging tool is completed by providing a retaining means on the jaw for retaining the ear tag portion. In a preferred arrangement, the retention means for the jaw 16 is a pin 38 and the retention means for the jaw 12 is an open ended slot 39 which is associated with a spring loaded catch 40. . An animal ear tagging tool having such a retaining device is suitable for the application of ear tags according to the applicant's Japanese Patent No. 829634. Reference may also be made to the applicant's Japanese Patent No. 829633 for a more detailed description of the catch 40, open ended slot 39 and pin 38.

Another embodiment of inter-assembling the halves B' and B'' of the animal ear tagging tool is shown in FIGS. 10 and 11. As in the previously described embodiment,
One half B' consists of a lever 10 in the shape of a handle, a main body part 11, and a clamp part 12, and the other half B'' consists of a lever 14, a main body part 15, and a clamp part, which are also shaped like a handle. 16. The bodies 11 and 15 each have an annular shape and have openings 17 and 18 extending radially and adjoining circular openings 19 and 20, respectively.

An elongated slot 50 is formed in a portion 15' of the main body portion 15 extending between the lever 14 and the clamping portion 16.
is provided. The portion 15'' of the body portion 15, which flares upwardly from the lever 14, is bifurcated so as to have an open-ended slot 51 therein which corresponds to the elongated slot 50 in the portion 15'. It is divided (see No. 14).

To assemble the animal ear tagging tool, the two halves B' and B'' are inserted into the section 15' by inserting the jaw portion 12 through the slot 50 so that the body portion 11 is completely enclosed within the body portion 15. combined by inserting it into

To keep the two halves B' and B'' of the animal ear tagging tool together, a bush 24 is inserted into the coaxial openings 19 and 20.
For positioning, annular projections 45 and 46 are provided.
are provided on either side of the main body portion 15, respectively. The edge 47 of the bushing 24 fits inside the protrusion 45, while the contracted end 4 of the bushing 24
8 fits within the perimeter of the protrusion 46. The bush 24 has openings 17 and 18 that are aligned in a straight line.
An opening 44 is provided which is in line with.

To hold the components in the assembled position, a threaded stop 43 is threaded through the hole 42 in the body 11 and into a threaded hole 49 in the bushing 24. This fastening device not only ensures mechanical coupling of the components, but also ensures that the bushing 24 has an alignment with the openings 19 and 18 of the body parts 11 and 15. The throat of the animal ear tagging tool formed by 20 closes during movement of the jaw 12 towards the jaw 16, i.e. towards the closed position of the animal ear tag tool. It also ensures that it is maintained so that it is not lost.

The animal ear tag application tool of the present invention has a throat that can accommodate the lower portion of the animal's ear when the ear tag is applied to the animal. The throat is at least partially formed by a centrally open pivot, so that even when the jaws 12 and 16 are brought closest together, the dimensions during ear tag attachment are reduced. is not restricted. It therefore never happens that the animal's ear gets caught between the two jaws of the animal ear tagging tool. Since the formation of the deep nip does not affect the effective distance between the retaining means and the rotation axis, the desired 2:1 lever ratio is maintained.

In yet another embodiment of the present invention, an animal ear tagging tool is provided in which the clip portion is not formed integrally with the main body portion, and the method disclosed in the specification of U.S. Pat. No. 4,120,303 is used. In this way, the clamping part can be made to pivot relative to the main body part. In this type, the jaws can be moved in a straight line towards each other and automatically retracted.
