Description

[Technical Field]

[0001] The present invention relates to an animal footwear attachment. [Background technology]

[0002] Conventionally, a known animal footwear fitting device used when putting animal footwear made of an elastic material on an animal's foot has a jaw that is inserted inside the opening of the animal footwear, and when the user grips a handle, the jaw opens and pushes open the opening of the animal footwear (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] U.S. Patent Application Publication No. 9833094 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with conventional animal footwear attachment devices, when an animal's foot is inserted into the animal footwear through the opening that has been pushed open by the jaws and the animal footwear is then removed from the jaws, the animal's foot is trapped between the jaws. This means that the user must hold the animal still while gripping the handle again to open the jaws and remove the animal footwear attachment device from the animal's foot. This means that putting animal footwear on an animal using conventional animal footwear attachment devices is time-consuming and places a great burden on both the user and the animal.

[0005] The present invention has been made in view of the above-mentioned problems, and has as its object to provide an animal footwear wearing device that allows an animal to easily wear animal footwear. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0009] The embodiment for carrying out the animal footwear wearing device of the present invention will be described below based on Example 1 shown in the drawings.

[0010] The animal footwear wearing device 1 of Example 1 shown in Figures 1 and 2 is used to put the animal footwear S shown in Figure 3 on the foot F of an animal D (e.g., a dog). Here, the animal footwear S is boot-shaped and includes a sole portion Sa that supports the sole of the foot, and an upper portion Sb that rises from the periphery of the sole portion Sa and covers the periphery of the foot F, and is integrally formed from an elastic body. The elastic body that forms the animal footwear S can be, for example, a silicone elastomer, a styrene elastomer, an olefin elastomer, a polyurethane elastomer, a polyester elastomer, an acrylic elastomer, natural rubber, etc.

[0011] As shown in Figures 4 to 9, the animal footwear wearing device 1 comprises a pair of first support shafts 11, 12, a pair of second support shafts 13, 14, a pair of stay members 15, 16, a pair of driven members 17, 18, four shaft holding members (first shaft holding member 19a, second shaft holding member 19b, third shaft holding member 19c, fourth shaft holding member 19d), a spring member 20 (biasing member), and a spring holding member 21.

[0012] 5 shows a front view of the animal footwear wearing device 1, and a back view of the animal footwear wearing device 1 is not shown because it appears the same as the front view shown in Fig. 5. Also, Fig. 6 shows a left side view of the animal footwear wearing device 1, and a right side view of the animal footwear wearing device 1 is not shown because it appears the same as the left side view shown in Fig. 6.

[0013] The pair of first support shafts 11, 12 are shaft members that are disposed opposite each other and extend parallel to each other. One of the first support shafts 11 is integrally molded with a first shaft holding member 19a and is fixed to a second shaft holding member 19b by a screw N1. As a result, the one first support shaft 11 is held by the first shaft holding member 19a and the second shaft holding member 19b. The other first support shaft 12 is integrally molded with a third shaft holding member 19c and is fixed to a fourth shaft holding member 19d by a screw N2. As a result, the other first support shaft 12 is held by the third shaft holding member 19c and the fourth shaft holding member 19d.

[0014] The pair of second support shafts 13, 14 are shaft members disposed between the pair of first support shafts 11, 12 in an opposing relationship. Here, the pair of second support shafts 13, 14 extend in a direction perpendicular to the pair of first support shafts 11, 12. One of the second support shafts 13 is integrally molded with the second shaft holding member 19b and fixed to the third shaft holding member 19c by a screw N3. As a result, the one second support shaft 13 is held by the second shaft holding member 19b and the third shaft holding member 19c. Meanwhile, the other second support shaft 14 is integrally molded with the fourth shaft holding member 19d and fixed to the first shaft holding member 19a by a screw N4. As a result, the other second support shaft 14 is held by the fourth shaft holding member 19d and the first shaft holding member 19a.

[0015] The pair of first support shafts 11, 12 and the pair of second support shafts 13, 14 are arranged on the same plane.

[0016] The pair of stay members 15, 16 are long, plate-like members that are rotatably held by the pair of first support shafts 11, 12, respectively, and are arranged opposite each other. The pair of stay members 15, 16 rotate in opposite directions. As shown in Figure 5 and other figures, each stay member 15, 16 is smoothly curved away from the other from its middle to one end.

[0017] The pair of stay members 15, 16 each have a narrower width in the middle of their longitudinal direction, with gripping portions 15a, 16a formed at one end and extension pieces 15b, 16b formed at the other end.

[0018] The gripping portions 15a and 16a are opposed to each other and are gripped by a user of the animal footwear wearing device 1. Furthermore, the gripping portions 15a and 16a have legs 15c and 16c formed at the ends in the longitudinal direction, respectively.

[0019] The leg portions 15c and 16c are formed at positions facing each other and are at least wider than the grip portions 15a and 16a. The leg portions 15c and 16c have support surface portions 15d and 16d, contact surface portions 15e and 16e, and non-contact surface portions 15f and 16f, respectively.

[0020] The support surfaces 15d, 16d are flat surfaces of predetermined areas formed on parts of the legs 15c, 16c. When the pair of stay members 15, 16 rotate in a direction that separates the opposing gripping portions 15a, 16a, and the extension pieces 15b, 16b and the driven extension pieces 17b, 18b (described later) alternately interfere with each other, the support surfaces 15d, 16d become parallel to a horizontal plane such as the ground (see FIG. 5, etc.).

[0021] The contact surfaces 15e and 16e are flat surfaces in predetermined areas formed on parts of the legs 15c and 16c, and come into contact with each other when the pair of stay members 15 and 16 rotate in a direction that brings the opposing gripping portions 15a and 16a closer to each other (see FIG. 13).

[0022] The non-contact surface portions 15f, 16f are surfaces that do not come into contact with each other when the contact surface portions 15e, 16e come into contact with each other. The non-contact surface portions 15f, 16f are formed on the peripheral edges of the contact surface portions 15e, 16e, i.e., between the end edges of the leg portions 15c, 16c and the contact surface portions 15e, 16e. In Example 1, the non-contact surface portions 15f, 16f are formed on both sides of the contact surface portions 15e, 16e in the width direction. The non-contact surface portions 15f, 16f are inclined in opposite directions as they move away from the contact surface portions 15e, 16e (see FIG. 7, etc.). Therefore, the distance between the non-contact surface portions 15f, 16f gradually increases as they move away from the contact surface portions 15e, 16e.

[0023] The expansion pieces 15b, 16b are portions to which the animal footwear wearing tool 1 is attached. The expansion pieces 15b, 16b are formed to have approximately the same width as the gripping parts 15a, 16a.

[0024] One stay member 15 has a shaft holding portion 15h, a first drive bevel gear 15i, and a second drive bevel gear 15j formed on its inner surface facing the other stay member 16. Furthermore, one stay member 15 has a reinforcing rib 15k extending over substantially the entire length of the stay member 15 and a spring holding portion (not shown) with projections and depressions on which the spring member 20 is hooked formed on its inner surface. Here, the spring holding portion is formed inside the grip portion 15a. The outer surface of the stay member 15 is formed to be a smooth surface without projections and depressions.

[0025] The shaft holding portion 15h is formed in the middle of the stay member 15 in the longitudinal direction, and one of the first support shafts 11 passes through it. The first drive bevel gear 15i is a conical gear formed around the shaft holding portion 15h. The second drive bevel gear 15j is a conical gear centered around the shaft holding portion 15h and facing the opposite side of the first drive bevel gear 15i (see FIG. 10).

[0026] The other stay member 16 has a shaft holding portion 16h, a third drive bevel gear 16i, and a fourth drive bevel gear 16j formed on its inner surface facing the one stay member 15. Furthermore, the inner surface of the stay member 16 has a reinforcing rib 16k extending over substantially the entire length of the stay member 16 and a spring holding portion (not shown) with projections and recesses on which the spring member 20 is hooked. The spring holding portion is formed inside the grip portion 16a. The outer surface of the stay member 16 is formed to be a smooth surface without projections and recesses.

[0027] The shaft holding portion 16h is formed in the middle of the stay member 16 in the longitudinal direction, and the other first support shaft 12 passes through it. The third drive bevel gear 16i is a conical gear formed around the shaft holding portion 16h. The fourth drive bevel gear 16j is a conical gear centered around the shaft holding portion 16h and facing the opposite side of the third drive bevel gear 16i (see FIG. 10).

[0028] The pair of driven members 17, 18 are plate-like members arranged opposite each other and rotatably held by the pair of second support shafts 13, 14. Each driven member 17, 18 has one end narrowed and the other end wider, on which driven extension pieces 17b, 18b are formed.

[0029] The driven expansion pieces 17b, 18b are formed in the same shape as the expansion pieces 15b, 16b and are disposed between the expansion pieces 15b, 16b. When the pair of stay members 15, 16 rotate in the direction that separates the gripping portions 15a, 16a, the expansion pieces 15b, 16b and the driven expansion pieces 17b, 18b alternately interfere with each other to form a tubular insertion portion T (see Figures 1, 5, 6, etc.) that can be inserted into the animal footwear S. When the expansion pieces 15b, 16b and the driven expansion pieces 17b, 18b alternately interfere with each other, their outer surfaces are smoothly continuous and are slightly curved outward in a plan view as shown in Figure 7.

[0030] One driven member 17 has a shaft holding portion 17h, a first driven bevel gear 17i, and a third driven bevel gear 17j formed on its inner surface facing the other driven member 18. Furthermore, a reinforcing rib 17k (see FIG. 7) is formed on the inner surface, extending over substantially the entire length of driven member 17. The outer surface of driven member 17 is formed to be smooth and free of irregularities.

[0031] The shaft holder 17h is formed at an end of the driven member 17, and one of the second support shafts 13 passes through it. The first driven bevel gear 17i is a conical gear formed around the shaft holder 17h. The third driven bevel gear 17j is a conical gear centered around the shaft holder 17h and facing the opposite side of the first driven bevel gear 17i. As shown in FIG. 10, the first driven bevel gear 17i meshes with the first drive bevel gear 15i, and the third driven bevel gear 17j meshes with the third drive bevel gear 16i.

[0032] The other driven member 18 has a shaft holding portion 18h, a second driven bevel gear 18i, and a fourth driven bevel gear 18j formed on its inner surface facing the one driven member 17. Furthermore, a reinforcing rib 18k is formed on the inner surface, extending over almost the entire length of the driven member 18. The outer surface of the driven member 18 is formed to be a smooth surface without any irregularities.

[0033] The shaft holder 18h is formed at an end of the driven member 18, and the other second support shaft 14 passes through it. The second driven bevel gear 18i is a conical gear formed around the shaft holder 18h. The fourth driven bevel gear 18j is a conical gear centered around the shaft holder 18h and facing the opposite side of the second driven bevel gear 18i. As shown in FIG. 10, the second driven bevel gear 18i meshes with the second drive bevel gear 15j, and the fourth driven bevel gear 18j meshes with the fourth drive bevel gear 16j.

[0034] The first shaft holding member 19a is integrally formed with one of the first support shafts 11. The second shaft holding member 19b is integrally formed with the other of the first support shafts 12. The third shaft holding member 19c is integrally formed with one of the second support shafts 13. The fourth shaft holding member 19d is integrally formed with the other of the second support shafts 14. The pair of stay members 15, 16, the pair of driven members 17, 18, and the first to fourth shaft holding members 19a to 19d are alternately arranged and fixed together by screws N1 to N4, with the one first support shaft 11 passing through the shaft holding portion 15h of one stay member 15, the other first support shaft 12 passing through the shaft holding portion 16h of the other stay member 16, the one second support shaft 13 passing through the shaft holding portion 17h of one driven member 17, and the other second support shaft 14 passing through the shaft holding portion 18h of the other driven member 18. As a result, the first to fourth shaft holding members 19a to 19d hold the first support shafts 11, 12 or the second support shafts 13, 14.

[0035] Furthermore, when the pair of stay members 15, 16 rotate in a direction that separates the opposing gripping portions 15a, 16a of the pair of stay members 15, 16, and the first to fourth shaft holding members 19a-19d, the pair of stay members 15, 16 form a smooth, continuous surface with almost no irregularities when the pair of stay members 15, 16 rotate in a direction that separates the opposing gripping portions 15a, 16a of the pair of stay members 15, 16, and the expansion pieces 15b, 16b and the driven expansion pieces 17b, 18b alternately interfere with each other (see FIG. 1). Note that the "smooth surface" here only needs to be smooth enough so that the user's fingertips, palm, etc. do not get caught on it.

[0036] The spring member 20 is a torsion coil spring having a coil portion 20a and a pair of arms 20b, 20c. The spring member 20 is held between a pair of stay members 15, 16, with one arm 20b engaging with a spring holding portion (not shown) of one stay member 15 and the other arm 20c engaging with a spring holding portion (not shown) of the other stay member 16. As a result, the spring member 20 urges the grip portion 15a of one stay member 15 and the grip portion 16a of the other stay member 16 outward, respectively. In other words, the spring member 20 urges the pair of stay members 15, 16 in a direction that moves the grip portions 15a, 16a away from each other.

[0037] In addition, when the gripping portions 15a, 16a of the animal footwear wearing device 1 are biased outward, the expansion pieces 15b, 16b and the driven expansion pieces 17b, 18b of the driven members 17, 18 are held in an alternating interference state (see Figure 1).

[0038] The spring holding member 21 has a spring holding shaft 21a that penetrates the coil portion 20a of the spring member 20, and is disposed between a pair of stay members 15, 16 to hold the spring member 20. Here, the spring holding member 21 is divided into two members: a first member 21b and a second member 21c. The first member 21b is fixed to the first shaft holding member 19a via a screw N5 and to the fourth shaft holding member 19d via a screw N6. The second member 21c is fixed to the second shaft holding member 19b via a screw N7 and to the third shaft holding member 19c via a screw N8.

[0039] The operation of the animal footwear wearing device 1 of the first embodiment will be described below with reference to FIGS.

[0040] To put the animal footwear S on the foot F of the animal D using the animal footwear wearing device 1 of Example 1, the user first folds the upper part Sb (opening) of the animal footwear S multiple times and then turns the animal footwear S inside out, as shown in Figure 14. This exposes the inner surface of the sole part Sa of the animal footwear S with the upper part Sb folded inward.

[0041] Then, the user places the animal footwear wearing device 1 on a horizontal surface such as the ground with the legs 15c, 16c facing downward, and allows the animal footwear wearing device 1 to stand on its own with the insertion part T facing upward (see Figure 1).

[0042] Here, the animal footwear wearing device 1 is provided with a spring member 20 that is disposed between the pair of stay members 15, 16 and biases the pair of stay members 15, 16 in a direction that separates the gripping portions 15a, 16a. That is, the animal footwear wearing device 1 is biased in a direction that separates the gripping portions 15a, 16a by the spring member 20. As a result, the gripping portions 15a, 16a of the animal footwear wearing device 1 open automatically, and the expansion pieces 15b, 16b and the driven expansion pieces 17b, 18b are held in a state where they alternately interfere with each other.

[0043] Furthermore, in the animal footwear wearing device 1 of Example 1, legs 15c, 16c are formed at the tips of the gripping portions 15a, 16a. The legs 15c, 16c have support surface portions 15d, 16d that become parallel to a horizontal plane when the pair of stay members 15, 16 rotate in a direction that separates the gripping portions 15a, 16a. When the animal footwear wearing device 1 is placed on a horizontal plane such as the ground with the legs 15c, 16c facing downward, the support surface portions 15d, 16d come into contact with the horizontal plane. As a result, the animal footwear wearing device 1 is supported by the support surface portions 15d, 16d and can stand stably on the horizontal plane.

[0044] Next, the user inserts his / her fingers inside the rolled-up upper portion Sb, unfolds the animal footwear S, and then places it over the insertion portion T, attaching the animal footwear S to the animal footwear wearing device 1 (see FIG. 15(a)). In other words, the animal footwear wearing device 1 is in a state where the insertion portion T is inserted into the animal footwear S that has been turned inside out after the upper portion Sb has been folded back.

[0045] At this time, since the animal footwear wearing device 1 is self-supporting, the user can use both hands to spread out the animal footwear S, making it easy to attach the animal footwear S to the animal footwear wearing device 1.

[0046] The user then picks up the animal footwear wearing device 1 with the animal footwear S attached and grips the gripping portions 15a, 16a. This causes the pair of stay members 15, 16 to rotate in a direction that brings the opposing gripping portions 15a, 16a closer together against the elastic force of the spring member 20 and the animal footwear S. As a result, as shown in Figure 11, the first drive bevel gear 15i and the second drive bevel gear 15j, and the third drive bevel gear 16i and the fourth drive bevel gear 16j, rotate simultaneously, and the extension pieces 15b, 16b move apart.

[0047] In the animal footwear wearing device 1, the first driven bevel gear 17i meshes with the first drive bevel gear 15i, and the third driven bevel gear 17j meshes with the third drive bevel gear 16i. In addition, the second driven bevel gear 18i meshes with the second drive bevel gear 15j, and the fourth driven bevel gear 18j meshes with the fourth drive bevel gear 16j.

[0048] Therefore, with the rotation of the pair of stay members 15, 16, the rotation of the first drive bevel gear 15i is transmitted to the first driven bevel gear 17i, and the rotation of the third drive bevel gear 16i is transmitted to the third driven bevel gear 17j. In addition, the rotation of the second drive bevel gear 15j is transmitted to the second driven bevel gear 18i, and the rotation of the fourth drive bevel gear 16j is transmitted to the fourth driven bevel gear 18j.

[0049] As a result, the first driven bevel gear 17i and the third driven bevel gear 17j, and the second driven bevel gear 18i and the fourth driven bevel gear 18j rotate simultaneously. That is, the pair of driven members 17, 18 rotate in synchronization with the rotation of the pair of stay members 15, 16. As shown in FIG. 11, the pair of extension pieces 15b, 16b and the pair of driven extension pieces 17b, 18b gradually tilt outward as the gripping portions 15a, 16a approach each other, and move apart evenly.

[0050] The pair of stay members 15, 16 then rotate until the contact surfaces 15e, 16e formed on the leg portions 15c, 16c come into contact with each other, and the insertion portion T opens as shown in Fig. 12. As a result, as shown in Fig. 15(b), the animal footwear S is pushed open from the inside with the upper portion Sb attached to the insertion portion T being rolled inward, and the sole portion Sa is stretched.

[0051] In the animal footwear wearing device 1 of Example 1, a pair of stay members 15, 16 are held by first support shafts 11, 12 arranged in parallel. In addition, a pair of driven members 17, 18 are held by second support shafts 13, 14 extending in a direction perpendicular to the first support shafts 11, 12. Therefore, in the animal footwear wearing device 1, the direction in which the pair of expansion pieces 15b, 16b expand the animal footwear S is perpendicular to the direction in which the pair of driven expansion pieces 17b, 18b expand the animal footwear S, and the upper portion Sb of the animal footwear S can be evenly expanded.

[0052] Furthermore, in the animal footwear wearing device 1 of Example 1, the leg portions 15c, 16c have contact surfaces 15e, 16e that come into contact with each other when the pair of stay members 15, 16 rotate in a direction that brings the opposing gripping portions 15a, 16a closer together. Therefore, when the pair of stay members 15, 16 rotate in a direction that brings the opposing gripping portions 15a, 16a closer together, the animal footwear wearing device 1 can stabilize the open state of the insertion portion T by bringing the contact surfaces 15e, 16e into contact with each other.

[0053] Furthermore, in the animal footwear wearing device 1, the leg portions 15c, 16c have non-contact surface portions 15f, 16f formed between the edge and the contact surface portions 15e, 16e, which do not come into contact with each other when the contact surface portions 15e, 16e come into contact with each other. Therefore, the animal footwear wearing device 1 can prevent hands from getting caught between the leg portions 15c, 16c.

[0054] Then, the user grasps the gripping portions 15a, 16a, opens the insertion portion T, and while spreading the animal footwear S, presses the sole portion Sa of the animal footwear S against the toes t of the animal D (see FIG. 15(c)).

[0055] The user may press the sole portion Sa into the insertion portion T to dent it before pressing the sole portion Sa against the toe t of the animal D. Furthermore, if the animal footwear S is small in size, the user may press the sole portion Sa of the animal footwear S into the inside of the insertion portion T to dent it while the animal footwear wearing device 1 is standing on its own (before the insertion portion T is opened). If the sole portion Sa is dented, the toe t pressed against the sole portion Sa is less likely to shift position, making it even easier for the user to put on the animal footwear S.

[0056] Once the toes t of the animal D and the sole portion Sa of the animal footwear S have been positioned, the user opens the hands that have been gripping the gripping portions 15a, 16a, as shown in Figure 15(d). Alternatively, the user loosens the gripping force on the gripping portions 15a, 16a. This causes the pair of stay members 15, 16 to rotate in a direction that separates the opposing gripping portions 15a, 16a due to the biasing force of the spring member 20 and the elastic force of the animal footwear S. As the pair of stay members 15, 16 rotate, the expansion pieces 15b, 16b move closer to each other.

[0057] Furthermore, the rotation of one stay member 15 is transmitted to the first driven bevel gear 17i via the first drive bevel gear 15i and to the second driven bevel gear 18i via the second drive bevel gear 15j. The rotation of the other stay member 16 is transmitted to the third driven bevel gear 17j via the third drive bevel gear 16j and to the fourth driven bevel gear 18j via the fourth drive bevel gear 16j. As a result, the pair of driven members 17, 18 rotate in the same direction as the pair of stay members 15, 16, and the driven extension pieces 17b, 18b move closer to each other.

[0058] That is, the pair of driven members 17, 18 rotate in synchronization with the rotation of the pair of stay members 15, 16, and the pair of expansion pieces 15b, 16b and the pair of driven expansion pieces 17b, 18b tilt inward, closing the insertion part T. Also, the animal footwear S fits snugly to the foot F of the animal D due to its own elasticity. Therefore, the animal footwear wearing device 1 can easily fit the animal footwear S snugly to the foot F of the animal D.

[0059] The user then moves his / her hands along the outer surfaces of the pair of stay members 15, 16 toward the expansion pieces 15b, 16b, pushing back and inverting the upper part Sb that has been rolled inward, and unfolding it (see Figure 15(e)).

[0060] Here, in the animal footwear wearing device 1 of Example 1, first to fourth shaft holding members 19a to 19d that hold the first support shafts 11, 12 or the second support shafts 13, 14 are arranged between a pair of stay members 15, 16 and a pair of driven members 17, 18. The outer surfaces of the pair of stay members 15, 16, the outer surfaces of the pair of driven members 17, 18, and the outer surfaces of the first to fourth shaft holding members 19a to 19d are smoothly continuous when the extension pieces 15b, 16b and the driven extension pieces 17b, 18b alternately interfere with each other.

[0061] Therefore, when the upper part Sb of the animal footwear fitting device 1 is pushed back by the user, the outer surface of the animal footwear fitting device 1 is less likely to catch on the animal footwear S or the user's hand, allowing the upper part Sb to be deployed smoothly.

[0062] Then, as the upper part Sb of the animal footwear S unfolds, it covers the circumference of the foot F of the animal D, and the animal footwear S is fitted to the foot F of the animal D. Meanwhile, as shown in Figure 15(f), the insertion part T of the animal footwear wearing device 1 unfolds, causing it to automatically slip out of the animal footwear S. This allows the animal footwear wearing device 1 to easily detach from the foot F of the animal D.

[0063] In this way, in the animal footwear wearing device 1 of Example 1, the insertion part T for expanding the animal footwear S is inserted into the turned-inside out animal footwear S after the upper part Sb has been folded back. In other words, in the animal footwear wearing device 1, the insertion part T is not inserted inside the animal footwear S. Then, the expansion pieces 15b, 16b and the driven expansion pieces 17b, 18b synchronously push out the animal footwear S, and as the upper part Sb of the animal footwear S unfolds, the animal footwear wearing device 1 slips out of the animal footwear S by itself.

[0064] As a result, the animal footwear wearing device 1 of Example 1 can wear the animal footwear S on the animal D and simultaneously remove it from the foot F of the animal D without the user having to grip or hold it again. As a result, the animal footwear wearing device 1 can easily wear the animal footwear S on the animal D, reducing the effort required by the user when wearing the animal footwear S. The user can then quickly wear the animal footwear S on the animal D, and the animal footwear wearing device 1 can reduce the burden on the user and the animal D.

[0065] The embodiments of the present invention have been described above in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes that do not deviate from the gist of the present invention are included in the present invention.
