Description

This disclosure relates to animal footwear.

Conventionally, footwear that protects the feet of animals such as dog socks and shoes that protect the feet of dogs has been proposed (for example, Patent Document 1).
In this prior art, dog socks made of a thermoplastic elastomer having a thickness of about 1 to 8 mm are disclosed.

Japanese Unexamined Patent Publication No. 2016-63777

In the above-mentioned conventional technique, the structure is closed as a whole except for the attachment / detachment opening for inserting / removing the foot when attaching / detaching to / from the animal's paw.
However, since dogs and cats have sweat glands on the paws on the soles of their feet to regulate body temperature, when they sweat when they wear footwear, the humidity and temperature rise inside the footwear, causing so-called stuffiness. May occur.
In addition, when the attachment / detachment opening is closed by the foot when the footwear is attached / detached, the air inside the footwear cannot be smoothly taken in and out. That is, since an elastic body having airtightness such as a thermoplastic elastomer has excellent elasticity, the footwear should be relatively smaller than the size of the foot, and the footwear should be stretched and worn. It is common to improve the adhesion with and to improve the wearability.

For this reason, when putting on footwear, if the foot is inserted halfway into the footwear and the attachment / detachment opening is closed, the volume of air that the foot enters cannot be discharged, and the inside becomes high pressure, which hinders the foot entry. It may take time to install.
On the contrary, when taking off the footwear, if the opening for attachment / detachment is blocked by the foot, it is difficult to smoothly introduce the volume of air that is pulled out from the footwear into the footwear, and the inside becomes negative pressure. The foot and footwear are kept in close contact with each other, and it may take time to remove the footwear.

The present disclosure has been made focusing on the above-mentioned problems, and an object of the present invention is to provide footwear for animals that can suppress stuffiness when attached to an animal's foot and has excellent workability for attachment / detachment to / from the foot. do.

The animal footwear of the present disclosure has a sole portion formed of an elastic body to support the sole of the animal, and an upper portion continuously formed on the peripheral edge portion of the sole portion and wrapping the foot. Animal footwear. The sole portion is provided with a ventilation hole having an outer opening opened on the side surface of the sole portion and an inner opening opened on the upper surface of the sole portion.

The animal footwear of the present disclosure is elastically deformed due to the deformation of the foot when running and walking while attached to the foot of the animal, and the internal space of the shoe expands and contracts, and accordingly, the air inside the footwear and the outside air pass through. It goes in and out through the pores. Therefore, even if the animal sweats on the paws on the soles of the feet, the humid and hot air does not stay in the footwear, and the stuffiness can be suppressed.
Further, since the outer opening of the ventilation hole is provided on the side surface of the sole portion, it is possible to suppress the intrusion of water as compared with the one provided on the lower surface of the sole portion, and the outer opening can be opened during running and walking. Breathability can be ensured without being blocked.
Further, when the animal footwear of the present disclosure is put on the foot, even if the foot is made to enter the inside of the footwear and the attachment / detachment opening is closed, the volume of air entering the foot is discharged to the outside from the ventilation hole. be able to. Therefore, the inside of the footwear does not become high pressure, and the animal footwear can be smoothly attached.
On the other hand, when removing the animal footwear attached to the foot, even if the attachment / detachment opening is closed, the volume of air that is taken out from the attachment / detachment opening enters the inside of the footwear through the ventilation hole, and the footwear There is no negative pressure inside. Therefore, the animal footwear can be smoothly removed from the animal's foot.

As shown in FIGS. 1A, 1B, and 2, the shoe S includes a sole portion 10 and an upper portion 20, and is integrally formed of an elastic body. The details of the elastic body will be described later.

The sole portion 10 is a portion that covers the sole Fa (see FIG. 2) of the foot F of the animal D (for example, a dog), and as shown in FIG. 6, the shape of the lower surface 11 is formed in a substantially oval shape. .. Note that FIG. 6 is a bottom view of the shoe S.

As shown in FIGS. 1A, 1B, and 2, the upper portion 20 includes a cap portion 21 and a body portion 22.
The cap portion 21 covers the upper surface and the left and right side surfaces of the toe FT of the foot F of the animal D, and is formed in a substantially semicircular arch shape.

The body portion 22 is continuously and integrally formed at the rear end portions of the cap portion 21 and the sole portion 10, and is formed in a cylindrical shape that covers the circumference of the foot F, and has a substantially circular attachment / detachment opening at the upper end portion. 22a is provided. The shoe S shown in the first embodiment is for a relatively large animal D, and is formed to have a total length of about 120 to 150 mm in the front-rear direction and a width of about 40 to 50 mm. Further, the attachment / detachment opening 22a is formed to have a radius (see FIG. 3) of about 10 to 15 mm.

The central axis of the body portion 22 is inclined at an angle such that it passes near the tip end portion of the sole portion 10, and the inclination angle of the upper surface of the cap portion 21 and the inclination angle of the body portion 22 are substantially equal to each other. Is formed in. As a result, the attachment / detachment opening 22a is the tip end portion of the sole portion 10 and is arranged so as to face substantially the front of the innermost end portion 31 of the shoe internal space 30. A strip-shaped pull strap 22b having a semicircular cross section is integrally provided on the upper portion of the body portion 22.

Further, as shown in FIG. 2, the sole portion 10 is formed so that the thickness of the posterior bottom portion 10b is thicker than the thickness of the front bottom portion 10a in the front-rear direction. As a result, on the upper surface 12 of the sole portion 10, a stepped portion 10c inclined backward is formed between the front side bottom portion 10a and the rear side bottom portion 10b.

Further, as shown in FIG. 6, on the lower surface 11 of the sole portion 10, a plurality of claw portions 11a and grooves 11b that cross the sole portion 10 are alternately arranged side by side in the front-rear direction.
The claw portions 11a are each formed in a mountain shape whose cross-sectional shape on the cut surface in the front-rear direction is convex downward, and the claw portions 11a arranged on the front bottom portion 10a are claw portions 11a arranged on the rear bottom portion 10b. The width in the left-right direction is narrower than that in the front-rear direction, and the space in the front-rear direction is widened.

Vent holes 13 and cushion holes 14 are arranged side by side in the rear bottom portion 10b of the sole portion 10.
As shown in FIGS. 7 and 9, the ventilation hole 13 includes a horizontal hole portion 13a and a vertical hole portion 13b.
The lateral hole portion 13a is penetrated across the sole portion 10 in the left-right direction, and has outer openings 13c and 13c on both left and right side surfaces of the sole portion 10. Further, the lateral hole portion 13a is formed in a shape in which the front-rear direction dimension and the vertical direction dimension gradually increase from the center of the sole portion 10 in the left-right width direction toward the outer opening portion 13c.

The vertical hole portion 13b has an inner opening portion 13d that extends upward from the center of the horizontal hole portion 13a in the left-right direction and is opened on the upper surface 12 of the sole portion 10, and has a front-rear direction dimension rather than a left-right direction dimension. It is formed in a large substantially rectangular cross-sectional shape. The left-right direction dimension and the front-back direction dimension are formed to have dimensions of about 4 to 6 mm.

The cushion hole 14 is formed at a position rearward of the ventilation hole 13, and includes a left side hole 14b and a right side hole 14c symmetrically with a blocking wall 14a provided at the center in the left-right direction.

Next, the elastic body forming the shoe S will be described.
The shoe S is formed of the elastomer 60 shown in FIG. 11 which has rubber elasticity and contains a hydrocarbon oil 50 which is liquid at room temperature. Note that FIG. 11 is an enlarged cross-sectional view schematically showing the components of the sole portion 10 of the shoe S.

As the elastomer 60, a silicone elastomer is used in the first embodiment. This silicone elastomer is an elastomer containing a silicon compound as a main component and an organopolysiloxane as a main chain. Silicone elastomers have the properties of being highly elastic and highly compressible because they are chemically stable compared to other organic polymers, have a small intermolecular force, and have a large coil forming ability. In addition, heat resistance, cold resistance, weather resistance, water resistance, steam resistance, electrical conductivity, electrical insulation, thermal conductivity, flame retardancy, oil resistance, solvent resistance, chemical resistance, abrasion resistance, and resistance. It has radiation properties. Further, it has a property that the tensile strength and the tear strength are higher than those of other organic polymers, and that it is originally transparent but has a high colorability to be colored in any color.

The hydrocarbon oil 50 contains a compound of carbon and hydrogen and a hydrocarbon which is a mixture of various compounds as a main component, and exhibits a liquid state at a temperature of 15 degrees and 1 atm. In the first embodiment, squalane is used. ing. Squalane is a hydrocarbon oil obtained by hydrogenating squalane, which is an unsaturated hydrocarbon, to obtain a saturated hydrocarbon. Here, synthetic squalene obtained by synthesizing from isoprene is also included. Squalene has an excellent emollient effect of preventing water evaporation from sebum, and can exert a moisturizing effect, an astringent effect, and a softening effect. It also has the effect of activating metabolism and adjusting skin turnover. Furthermore, since squalene originally exists in the body of humans and animals, squalene is not recognized as a foreign substance when applied to sebum, and is easily permeated into the body. Therefore, it can act as a barrier for sebum as well as a natural sebum film, and by applying squalane to the skin, it is possible to protect the skin from germs and the like.

The hydrocarbon oil 50, which is squalane, is contained in the elastomer 60 by penetrating between a large number of molecules constituting the elastomer 60. The content of the hydrocarbon oil 50 in the elastomer 60 is, for example, about 2%.

(Action of Embodiment 1)
Next, the operation of the shoe S of the first embodiment will be described.
First, the need for smooth attachment and detachment, the need for breathability, and the need for moisturizing and protecting the soles of the feet will be explained. Then, the action of the shoe S of the first embodiment will be described separately by dividing it into "smoothness of putting on and taking off", "breathability of the shoe", "moisturizing action of the sole", and "protecting the sole of the foot".

"Necessity of smoothness of putting on and taking off shoes"
Many animals D dislike being touched by the foot F, and in particular, when the shoes S are put on for the first time, they often dislike this.
Therefore, when the animal D is to be put on the shoes S, those that can be put on smoothly in a short time are preferable.

"Necessity of breathability of shoes"
Dogs and cats have sweat glands called eccrine glands that regulate body temperature in their paws. Therefore, animals such as dogs and cats may sweat from their paws when their body temperature rises.
Therefore, when sweating from the paws when the shoes S are worn, those capable of smoothly discharging moisture and heat to the outside of the shoes S are preferable.

"Necessity of moisturizing and protecting the soles of the feet"
The toe FT of animal D such as dogs and cats generally consists of a finger part with claws and a part called a paws where the skin is exposed, and most of the ground contact surface (sole) of the toe FT is a paws. Is. This paws play a cushioning role during exercise, absorb the impact during exercise to protect the bones and joints of the foot F, and moisten the paws with sweat to prevent slipping. ..

On the other hand, the paws become dry, hardened and keratinized due to walking on asphalt on daily walks and chemical agents for flooring. The hardened paws are slippery and can cause joint problems, hernias, and fractures due to falls.

Also, in the senior stage, a thick layer of stratum corneum is formed on the paws, and the paws may become whitish and rough. If left in this state, a cut like a rhagades will be formed, and bleeding or germs may enter from the cut and cause an unexpected illness. In addition, the dryness of the paws often causes them to slip during walking, which can adversely affect the formation of the skeleton.

As described above, since the drying of the sole Fa of the animal D damages the paws and causes unexpected troubles, it is preferable to moisturize the sole Fa.
Therefore, it is important to prevent and protect the sole Fa from drying out.

Hereinafter, the "smoothness of putting on and taking off", "breathability of shoes", "moisturizing effect on the sole of the foot", and "protecting effect on the sole of the foot" by the shoes of the first embodiment will be described.
"Smoothness of putting on and taking off"
In the shoe S, the body portion 22 is inclined substantially in a straight line with respect to the upper surface of the cap portion 21, and the attachment / detachment opening 22a is arranged substantially in line with the innermost end portion 31 of the shoe internal space 30. The attachment / detachment opening 22a is arranged so as to face the front of the innermost end portion 31.

Therefore, when the shoe S is put on the foot F of the animal D, the toe FT can be inserted linearly from the attachment / detachment opening 22a to the innermost end 31. Therefore, for example, the cap portion 21 and the body portion 22 can be mounted linearly and smoothly in a short time as compared with those having a substantially right angle as described in Patent Document 1.

Moreover, since the pull strap 22b is provided on the upper part of the body portion 22, the body portion 22 can be easily pulled up along the foot F, which also makes it possible to put on the shoes S smoothly in a short time.

By the way, when the shoe S is put on the foot F of the animal D, when the foot F is inserted into the body portion 22 to some extent, the attachment / detachment opening 22a is closed by the foot.
Since the shoe S of the first embodiment has abundant elasticity, it is preferable to select a shoe S having a smaller size than the foot F and put it on in a state where the adhesion (fitness) to the foot F is improved. That is, by putting on the shoes with high adhesion (fitness), the shoes S are less likely to move relative to the foot F during walking, and the walking performance is excellent.

As described above, when the adhesion (fitness) is improved, especially when the shoes S are put on, the attachment / detachment opening 22a is easily closed by the foot F during the putting on.
In the shoe S of the first embodiment, since the shoe internal space 30 communicates with the outside of the shoe through the ventilation hole 13, the foot F can be used as the shoe internal space even when the attachment / detachment opening 22a is blocked. The volume of air inserted into 30 smoothly escapes from the ventilation hole 13 to the outside of the shoe.

Therefore, even if the attachment / detachment opening 22a is closed, the shoe internal space 30 does not become high pressure as the foot F enters the shoe internal space 30, and the shoe S can be smoothly moved to the foot F in a short time. Can be put on.

Further, even when the shoe S is taken off, the attachment / detachment opening 22a is closed, and the air corresponding to the volume of the foot F pulled out from the body portion 22 is smoothly introduced into the shoe internal space 30 from the ventilation hole 13. be able to. Therefore, the shoe internal space 30 does not become negative pressure and the shoe S does not come into close contact with the foot F, and the shoe S can be smoothly removed.

"When running / walking"
Next, the running / walking time while wearing the shoes S will be described.
The sole portion 10 of the shoe S has a stepped portion 10c between the front side bottom portion 10a and the rear side bottom portion 10b. Therefore, when the animal D wearing the shoes S is running or walking, the toe FT of the animal D is difficult to move back and forth, and the running and walking performance are excellent. Specifically, the rear end of the palm ball portion of the animal D's paws is fitted with shoes S having a size arranged in front of the step portion 10c, so that the palm ball portion is caught by the step portion 10c and the toes are toeed. It is possible to suppress the FT from moving back and forth with respect to the sole portion 10.

Next, the air permeability during running and walking will be described.
When the animal D wearing the shoes S is running or walking, the upper portion 20 elastically deforms with respect to the sole portion 10 in the front-rear direction, and the volume of the shoe internal space 30 changes with this elastic deformation. Then, the air corresponding to the volume change goes in and out between the shoe internal space 30 and the shoe outside through the ventilation hole 13, and the shoe internal space 30 is ventilated.

Therefore, even if the animal D sweats on the paws of the sole Fa, it is possible to suppress the increase in the humidity and temperature of the shoe internal space 30.

In addition, the inner opening 13d of the ventilation hole 13 is opened on the upper surface 12 of the sole portion 10 and is arranged at a position close to the paws at the time of mounting. Therefore, for example, when the upper portion 20 of the shoe S is provided with an opening. Compared with, the moisture due to the sweat of the paws can be efficiently discharged.

Further, in the ventilation hole 13, the inner opening 13d is provided on the upper surface 12 of the sole portion 10, while the outer opening 13c is provided on the side surface of the sole portion 10. Therefore, when ventilating through the ventilation hole 13, the outer opening 13c is not blocked in contact with the ground, and smooth ventilation is possible.

In addition, by having the outer opening 13c, there is a possibility that water may infiltrate into the shoe internal space 30 through the ventilation hole 13 in rainy weather or the like.
However, in the first embodiment, since the outer opening 13c of the ventilation hole 13 is provided on the side surface of the sole portion 10, it is compared with the one opened from the inner opening 13d to the lower surface 11 of the sole portion 10 directly below. , It is possible to suppress the infiltration of water into the shoe internal space 30.

Further, since the inner opening 13d is provided on the upper surface 12 of the sole portion 10, if water enters the shoe internal space 30, it is easy to discharge the water along with the ventilation by the ventilation hole 13, and the shoe internal space is easily discharged. It is possible to prevent water from accumulating in 30. Also in this case, since the outer opening 13c is provided on the side surface of the sole portion 10, the outer opening 13c is not blocked when the water is discharged, and the water can be smoothly discharged.

"Foot moisturizing effect"
When the foot F of the animal D is inserted into the shoe S of the first embodiment and the shoe S is attached to the foot F of the animal D, as shown in FIG. 2, the paws of the sole Fa are on the upper surface 12 of the sole portion 10. Contact. Then, the animal D will step on the upper surface 12 of the sole portion 10 by the sole Fa (paws) during running and walking.

In the shoe S of the first embodiment, the sole portion 10 is formed of an elastomer (silicone elastomer) 60 having rubber elasticity and containing a hydrocarbon oil 50 which is squalane. Further, the hydrocarbon oil 50 is liquid at room temperature and permeates between a large number of elastomer molecules constituting the elastomer 60.

Therefore, the hydrocarbon oil 50 gradually seeps through, for example, the upper surface 12 of the sole portion 10 with the passage of time, and a film of the hydrocarbon oil 50 is constantly formed on the upper surface 12. On the other hand, the hydrocarbon oil 50 exuded on the upper surface 12 of the sole portion 10 adheres to the sole Fa of the animal D and forms a film on the surface of the sole Fa.

Here, the hydrocarbon oil 50, which is squalane, can exert an emollient effect and a moisturizing effect of preventing water evaporation from sebum, and can also permeate into the body and act as a barrier of sebum. Therefore, it is possible to prevent water from being lost from the paws of the sole Fa due to the adhesion of the hydrocarbon oil 50 to the sole Fa, and it is possible to moisturize the sole Fa.

Further, since the hydrocarbon oil 50 gradually seeps out to the upper surface 12 of the sole portion 10, a film can always be formed on the upper surface 12 of the sole portion 10. Therefore, the hydrocarbon oil 50 can be attached to the sole Fa of the animal D every time the shoe S is put on, and it does not take time and effort. Further, even if the state of the sole Fa cannot be visually confirmed, the hydrocarbon oil 50 seeps out from the elastomer 60, so that it is possible to constantly moisturize the foot, and it is not necessary to confirm the state of the sole. be able to.

Therefore, by putting the shoe S on the animal D, it is possible to easily moisturize the sole Fa of the animal D.

[Foot protection]
In the shoe S of the first embodiment, the sole portion 10 is formed of the elastomer 60 containing the hydrocarbon oil 50. Here, the elastomer 60 has the property of being highly elastic and highly compressible. Therefore, it can be easily deformed, the impact on the sole Fa can be absorbed, and the sole Fa can be protected.

In addition, by having the ventilation holes 13 and the cushion holes 14, the amount of elastic deformation of the sole portion 10 in the vertical direction is larger than that without these holes, and the shock absorption performance is improved. It will increase further. Moreover, since the cushion holes 14 are formed in parallel in addition to the ventilation holes 13 for obtaining the above ventilation performance, the flexibility of the sole portion 10 is further increased, and the shock absorption performance can be improved.

Then, when the sole portion 10 and the upper portion 20 are elastically deformed during running / walking, a restoring force that tries to return to the original shape acts, and this restoring force also assists running and walking. .. Therefore, when an animal D with reduced walking ability such as an old dog walks, it is possible to assist running / walking with the restoring force of the shoes S at the time of elastic deformation and reduce the burden during running / walking. be.

Further, since the elastomer 60 is a silicone elastomer, it has heat resistance, cold resistance, water resistance, steam resistance, etc., and protects the sole Fa of the animal D from heat, cold, water, dirt, and the like. Can be done. Therefore, by putting the shoe S on the animal D, the sole Fa of the animal D can be protected.

The hydrocarbon oil 50 contained in the elastomer 60 can seep out from the elastomer 60 and then seep into the lower surface 11 of the sole portion 10. As a result, a film of the hydrocarbon oil 50 is also formed on the lower surface 11, and the film of the hydrocarbon oil 50 becomes a non-slip, and the lower surface 11 of the sole portion 10 can be prevented from slipping.

(Embodiment 2)
The shoe SB of the second embodiment shown in FIGS. 13 to 15 will be described.
This shoe SB is different in size from the shoe S of the first embodiment and is for relatively small animals.

This shoe SB includes a sole portion 210 and an upper portion 220, as in the first embodiment. Further, the sole portion 210 is provided with a ventilation hole 213 and a cushion hole 214.

Further, the upper portion 220 includes a cap portion 221 and a body portion 222. The body portion 222 includes a detachable opening (not shown) and a pull strap 222b.

The difference from the shoe S of the first embodiment of this shoe SB is that the total length in the front-rear direction and the width in the left-right direction are formed to be about two-thirds of the total length and width of the shoe S. .. Further, for example, the total length is about 90 mm and the width is about 25 mm.

Further, the shape of the ventilation hole 213 formed in the sole portion 210 is different from that of the ventilation hole 13 of the first embodiment, and the lateral hole 213a is formed in a constant cross-sectional area shape. The shape of the ventilation hole 213 may be applied to the shoe S of the first embodiment, or the ventilation hole 13 shown in the first embodiment may be applied to the shoe SB of the second embodiment. ..

Even in the shoe SB of the second embodiment described above, the effects described in (1) to (11) above can be obtained.

Although the embodiments of the present disclosure have been described above with reference to the drawings, the specific configuration is not limited to this embodiment and is not limited to the present embodiment as long as it does not deviate from the gist of each claim. , Design changes and additions are allowed.

In the first embodiment, the elastomer is shown as the elastic body for forming the animal footwear (shoes S), but the present invention is not limited to this, and other elastically deformable materials may be used. Further, in the embodiment, an example in which the elastomer 60 is a silicone elastomer is shown. However, the elastomer 60 is not limited to this, and may be any elastomer 60 having rubber elasticity. For example, natural rubber, styrene elastomer, olefin elastomer, polyurethane elastomer, polyester elastomer, acrylic elastomer may be used. All of them have rubber elasticity, and each of them has one of properties such as heat resistance, cold resistance, water resistance, mechanical strength, abrasion resistance, weather resistance, and oil resistance.

In addition, natural rubber is purified from (milky lotion) contained in the sap of natural rubber tree, and its component is chemically high cispolyisoprene. Further, the styrene elastomer has a basic unit structure in which a hard segment made of polystyrene and a soft segment made of polyethylene / polybutylene are copolymerized in a block shape. The olefin elastomer is generally a thermoplastic elastomer in which ethylene-propylene rubber is finely dispersed in polypropylene. Urethane elastomers have hard segments formed from low molecular weight diols and diisocyanates and soft segments formed from high molecular weight diols and diisocyanates. The polyester elastomer is obtained by polycondensing a dicarboxylic acid or a derivative thereof and a diol compound or a derivative thereof. The acrylic elastomer is obtained by copolymerizing an acrylic acid ester with a monoweight having an epoxy group and a vinyl-based monoweight.

Further, in the embodiment, the elastic body contains the hydrocarbon oil 50 which is liquid at room temperature, and an example in which squalane is used as the hydrocarbon oil 50 is shown. However, the hydrocarbon oil 50 is not limited to squalane as long as it remains liquid at room temperature, has a moisturizing function, and can be contained in the elastomer 60. For example, the hydrocarbon oil 50 may be liquid paraffin or squalene.

Here, the liquid paraffin is a tasteless, odorless, colorless and transparent oily liquid obtained by highly refining a lubricating oil fraction having a relatively low viscosity of petroleum. Squalene is also present in cod liver oil of deep-sea fish, especially sharks, or in vegetable oils such as olive oil, rice bran oil, wheat germ oil, sesame oil, and cottonseed oil, and is also found in human skin oil. Also exists. Squalene can be obtained by extracting from these. All of these are liquids at room temperature and can exert a high moisturizing effect when applied to the skin.

Further, in the embodiment, the cushion hole 14 has an example of having a blocking wall 14a in the middle, but the present invention is not limited to this, and the cushion hole 14 may be penetrated by the entire length.
Further, the upper portion 20 shows an example in which the attachment / detachment opening 22a of the body portion 22 is inclined so as to face the innermost end (tip portion) 31 of the shoe internal space 30, but the shape thereof is limited to this. However, as described in Patent Document 1, the body portion may be upright with respect to the sole portion or at an angle close to it.
