Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is particularly useful for cooling the head of a racehorse transported from a stable to a stadium, and also for cooling the horse's head in order to suppress a rise in body temperature after the competition, so that the physical condition is maintained. (Hereinafter, may be simply referred to as a harness). ADVANTAGE OF THE INVENTION The harness of this invention has a soft touch, it is excellent in a wearing feeling, a horse does not feel uncomfortable, and a horse does not detach from itself. Also, you can get fit and calm down the horses that you enter.

[0002]

2. Description of the Related Art Horse body temperature has been conventionally controlled by directly applying water to the horse body. However, in order to apply water, a water supply system is required in the vicinity, and after applying water, it must be wiped off, which is a labor-intensive operation. On the other hand, when transporting a racehorse from a stable to a stadium, a dedicated transport vehicle equipped with air conditioning may be used. However, horses with poor thermoregulatory functions
If you suddenly get out of a cold place in a transport vehicle and reach a high temperature, many of them may become ill and die. However, using a transport vehicle without air conditioning equipment is also a problem because the horse becomes ill.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has a harness main body capable of covering the frontal part of the horse and the upper part of the nape, and is detachably mounted inside the harness main body. An object of the present invention is to provide a head cooling harness including a plurality of coolants. In the harness of the present invention, a large number of relatively small coolants are used, and particularly, by attaching the coolant to the harness main body with a hook-and-loop fastener, a harness excellent in wearing feeling can be obtained.

[0004]

According to a first aspect of the present invention, there is provided a head cooling harness comprising a harness main body, a plurality of coolants, and attachment means for attaching the coolant to the harness main body. A cooling harness, wherein the harness main body can cover at least the upper part of the nape from the frontal part of the horse, and the coolant is detachably attached to the surface of the harness main body on the side in contact with the horse body. It is characterized by having.

[0005] The "harness main body" must be excellent in a feeling of wearing, and is preferably a flexible one obtained by cutting a sheet of vinyl leather or the like into a required shape and sewing the sheet. Since the harness main body does not receive such a strong force, the thickness of the sheet is 0.5 to 2 mm, particularly 1 m.
m. In addition, after the surface is subjected to graining, for example, by coloring blue, green, etc.,
The appearance can also be improved.

[0006] Further, it is preferable that the periphery of the harness main body is edged and strengthened with an appropriate woven cloth or the like. The shape and dimensions of the harness main body do not need to be particularly changed depending on the horse body if it is a general competitive horse, and the same shape and dimensions can be used. The harness main body may be provided with holes at predetermined positions for projecting both ears of the horse. The position of the hole does not need to be changed depending on the horse body, and may be provided at a predetermined predetermined position. In addition, it is preferable that the periphery of the hole is similarly edged with a woven fabric or the like to strengthen the hole.

The harness main body may be cylindrical, but if the diameter is reduced, it is difficult to mount the harness on the horse body, and the feeling of wearing is reduced. On the other hand, if the diameter is increased, the harness can be easily attached, but the harness cannot be securely attached to a required position. Therefore, the second
As in the present invention, it is preferable that the harness main body is formed in a "sheet shape" and both ends thereof are engaged by "locking means". This makes it possible to appropriately and easily adjust the circumferential dimension of the harness attached to the horse body. Therefore, irrespective of individual differences between horses, it is possible to more securely attach the horse and to improve the feeling of wearing.

As the above-mentioned locking means, the first "surface fastener" is suitable as in the third invention. The hooks, buttons, etc., come into contact with the horse body as projections, and the horse sometimes dislikes it and removes the harness itself. However, the hook-and-loop fastener does not have such a thing at all, and the wearing feeling is not impaired. Also, this hook-and-loop fastener
Although it may be directly attached to both ends of the sheet-like harness main body, as in the fourth invention, a member constituting a hook-and-loop fastener is attached to the other end of the “stretchable belt” attached to the end of the harness main body. Is preferred. Thereby, the flexibility of the harness in the circumferential direction is further increased, and the harness can be more easily and reliably attached, and the feeling of wearing is also improved.

[0009] The "coolant" is detachably attached to the harness main body at the "surface on the side in contact with the horse body". The number of the coolant may be an appropriate number according to the amount of the regenerator filled in each coolant, the area requiring cooling, and the like. The planar shape of the coolant is not particularly limited, and may be any of a square, a triangle, a circle, an ellipse, and the like. The size of the horse is not specified, but if it is too large, it will not conform to the outer shape of the horse's head and neck, and will not fit well when the regenerator is frozen. The space becomes large and the cooling efficiency also decreases.
On the other hand, if it is too small, each of the coolants feels like pressing foreign matter, and the horse dislikes it, which is not preferable.

In the present invention, it is preferable that the coolant is composed of a flexible container made of resin and a regenerator filled therein. As a resin container, polyethylene,
Those formed of a film made of a resin such as polypropylene, polyamide, or polyvinyl chloride are preferable.
The container made of the resin film has sufficient strength as it is, is not easily damaged, and does not leak the regenerator. However, since it is necessary to provide an attaching means for attaching the coolant to the harness main body, it is possible to store the “resin-made flexible container” in the resin-made “net” as in the fifth invention. preferable. By using such a mesh, the cold surface of the resin container does not directly touch the horse body, but becomes indirect contact through an air layer, and the use of the mesh is preferable in this sense. .

Further, the temperature of the surface of the coolant during use is set to “−” while the frozen regenerator is melted as in the sixth invention.
5 ° C. to 0 ° C. ”. If the temperature of the surface of the coolant is at this level, the temperature felt by the horse is 0 to 10
° C, which keeps the horse in good condition. In many cases, the stable and the stadium are not so far from each other, but often within about one hour by a transport vehicle.
Therefore, the time for maintaining the above-mentioned appropriate temperature may be one hour or slightly longer. For this reason, a horse with a normal body temperature requires about 800 to 1200 g of the above-mentioned regenerator, and if one coolant is filled with, for example, 80 g of regenerator, about 10 to 15 refrigerants Wood is needed.

Further, since it is the horse body that needs to be cooled and the harness main body side does not need to be cooled, the surface of the coolant facing the harness main body is provided with a "heat insulating material" as in the seventh invention. Are preferably laminated or interposed. As the heat insulating material, a resin film, cloth, etc. can be used,
A foamed resin sheet which is flexible and has a large heat insulating effect is preferable. This foamed resin sheet has a sufficient heat insulating property even if it is thin, and a sheet having a thickness of about 0.5 to 2 mm, especially about 1 mm is usually sufficient. In the case where a mesh is used as in the fifth invention, the heat insulating material made of the foamed resin sheet can be used by being interposed between the resin container and the mesh.

The foamed resin sheet is not particularly limited, and various known foamed resin sheets can be used. As such a foamed resin sheet, a sheet made of a resin foam such as foamed polyethylene, foamed polypropylene, foamed polyurethane, and foamed polystyrene can be used. Also, a sheet made of a foam such as an ethylene vinyl acetate copolymer or an ethylene acrylate copolymer can be used.
Among these, a foamed polypropylene sheet and a foamed polyethylene sheet which have relatively high strength and are excellent in low-temperature brittleness and the like are preferable.

Although the "attachment means" for attaching the coolant to the harness main body is not specified, projections such as hooks and buttons are not attached to the horse as in the case of engaging both ends of the sheet-like harness main body. Those that give a pleasant sensation are not preferred.
It is preferable that the attachment means also uses the second "surface fastener" as in the eighth invention. In the second hook-and-loop fastener, one member may be attached to a required portion of the surface of the harness main body on the side in contact with the horse body, and the other member may be attached to one surface of the coolant. Note that, as in the ninth invention, the "entire surface of the surface in contact with the horse body" of the harness main body may be one member of the second hook-and-loop fastener. In this way, the coolant can be attached to any location, and the physical condition of the horse can be managed more effectively by attaching it to the optimal position while taking into consideration the physical condition of each horse. .

In general, the regenerator used in the application of the present invention is preferably one which freezes in a short time, requires less energy for freezing, and has a long effective cold-retention time. Practically, a mixture of water having a large latent heat of fusion and a gelling agent added thereto is frequently used. In the present invention, as the above-mentioned "cool storage agent", water is used as a main agent, and a gelling agent and a chilling agent are appropriately added thereto. Can be used without.

As the above-mentioned gelling agent, a highly water-absorbing polymer which is made water-insoluble by crosslinking a hydrophilic polymer such as carboxymethylcellulose, polyvinyl alcohol, sodium polyacrylate and polyacrylamide can be used. In addition, natural polysaccharides such as starch, gelatin, and guar gum can also be used. This gelling agent is usually added in an amount of about 1 to 5 parts by weight, especially about 1 to 3 parts by weight, based on 100 parts by weight of the regenerator.
The viscosity of the regenerator decreases with a decrease in the amount of the gelling agent, and when the regenerator is filled in a container, for example, the handleability is improved. .

Examples of the cryogen include metal salts of inorganic acids such as sodium chloride and potassium chloride and polyhydric alcohols such as ethylene glycol and propylene glycol. These cryogens depend on the desired melting point of the regenerator,
The required amount may be added to water.

Further, when these regenerators are in a supercooled state, a long time is required for freezing and a large amount of energy is required. Therefore, a nucleating agent may be blended so as to quickly freeze near the melting point. In many cases, a nucleating agent may be added to the regenerator of the present invention if necessary. The nucleating agent serves as ice crystal nuclei for freezing the cold storage agent, and includes silver iodide, methaldehyde, α
-Inorganic or organic compounds such as phenazine, steroids can be used. In addition, as the nucleating agent, bacteria having activity as a certain nucleating agent, microorganisms such as marine phytoplankton, moss, and the like can also be used. In addition, the cold storage agent may further contain additives usually used in this type of cold storage agent, such as an antiseptic, an antifungal agent, and a color paste, in an amount not to impair the properties thereof, if necessary. You can also.

It is well known that a horse is a delicate animal. However, like the head cooling harness of the present invention, the horse is flexible and excellent in wearing feeling, and is particularly suitable for horses such as hooks and buttons. When a hook-and-loop fastener that does not give a foreign object feeling is used, a harness with better performance can be obtained. On the other hand, as the harness for cooling the head as in the present invention, a structure in which the harness itself is used as a container and a cool storage agent is filled therein is also conceivable.
In this way, unlike the harness of the present invention, there is no need to attach and remove a plurality of coolants, and handling may be easier. However, when the harness main body is formed as a single container, the shape does not always conform to the horse body when the regenerator is frozen, and it is inevitable that the wearing feeling deteriorates.

Incidentally, the harness main body is divided into appropriate sizes,
Head cooling harnesses that are structured like a collection of small independent coolants are also contemplated. Although the wearing feeling of the harness may not be sufficiently satisfactory, the wearing feeling is expected to be considerably improved as compared with the case where the harness main body is formed as one container. In addition, a mesh or the like for accommodating the resin container filled with the regenerator is fixed to the harness main body, and after using the harness, the resin container is taken out of the net and cooled to freeze the regenerator. After that, when used again, or when stored in a net-like body, a head cooling harness excellent in wearing feeling and the like can be obtained.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to embodiments. (1) Production of coolant and evaluation of its performance Production of coolant The coolant shown in FIG. 1 together with the harness main body was produced as follows. 30 parts by weight of sodium polyacrylate was blended as a nucleating agent with respect to 100 parts by weight of water to prepare a regenerator having a melting point of 0 ° C. 60 g or 40 g of this regenerator was filled in a square container 21 made of a polyvinyl chloride film and having a side of 90 mm, and the container 21 was housed in a net 22 made of polyamide fiber to prepare the coolant 2.

Evaluation of the performance of the coolant The above-mentioned coolant was allowed to stand still in a freezer compartment adjusted to -25 ° C.
The regenerator was frozen. In addition, the cold storage agent was frozen in the same manner also for the heat insulating material not stored in the net. After the regenerator was frozen, the coolant was taken out of the freezer and left standing in an atmosphere adjusted to 35 ° C., and the progress of the temperature increase was compared. The temperature was measured with a thermocouple inserted into the regenerator of each coolant. This change in temperature is shown in FIG. In FIG. 4, ● and ● show the temperature change when the mesh is used. In addition, △ indicates a temperature change when the net is not used, and □ indicates a temperature change when the net is not used and the amount of the regenerator is as small as 40 g.

Evaluation Results of Cooling Performance According to the results shown in FIG. 4, when the mesh is used, the temperature of the regenerator is kept at 0 ° C. or less until 90 minutes have passed, and even after 2 hours, the temperature of the regenerator remains at 4 ° C. is there. Therefore, the temperature felt by the horse through the film container and the net is several degrees C to 10 degrees C at most.
It is estimated that the appropriate temperature will be maintained for the required time. On the other hand, even when the reticulated body is not used, the temperature is kept at 0 ° C. or lower until the lapse of 90 minutes. However, after a lapse of 90 minutes, the temperature rapidly rises, and after 2 hours, the temperature rises to 20 ° C. Therefore, anxiety remains when the time required to carry the horse is prolonged. In addition, when the amount of the regenerator is reduced, the time required for rapid temperature rise is short as expected, and the temperature already starts after 60 minutes, so it is necessary to pay attention to the amount of the regenerator during actual use. You can see that there is.
