DETAILED DESCRIPTION OF THE INVENTION

[0008] An exercise device 1 for small animals according to this embodiment and a breeding container 10 equipped with the same will be described with reference to Figs. 1 to 8. Note that in each drawing, the dimensional ratios shown in the drawing do not necessarily match the actual dimensional ratios, and the dimensional ratios between the drawings do not necessarily match either. Fig. 1 is a perspective view of the breeding container 10, Fig. 2 is an exploded perspective view of the breeding container 10, Fig. 3 is a front view of the breeding container 10, and Fig. 4 is an enlarged cross-sectional view taken along line IV-IV in Fig. 3.

[0009] 1 to 4, breeding container 10 is a container for breeding small animals such as hamsters, chinchillas, squirrels, etc. From the viewpoint of allowing good observation of the small animals, breeding container 10 is preferably made of a transparent material (for example, transparent glass or transparent resin).

[0010] The breeding container 10 is formed, for example, in an approximately rectangular parallelepiped shape and includes a container-shaped bottom wall member 11 that opens upward, a front wall member 12 that stands along the periphery of the opening of the bottom wall member 11, a pair of side wall members 13 and a rear wall member 14 (see Figure 4), and a lid member 15 that covers the upper opening formed by each of the members 12 to 14.

[0011] The bottom wall member 11 is formed, for example, in the shape of a rectangular bowl. Leg portions 111 (see FIGS. 3 and 4) that are circular in plan view are provided at the four corners of the bottom surface of the bottom wall member 11. A flange 113 (see FIGS. 2 and 4) that has an L-shaped cross section and protrudes outward from the peripheral wall 112 is provided at the upper end of the peripheral wall 112 of the bottom wall member 11. The flange 113 extends along the upper end (periphery of the opening) of the peripheral wall 112 so as to surround the opening of the bottom wall member 11. The tip of the flange 113 extends upward.

[0012] The upper end of the peripheral wall 112 has a plurality of notches 114 (see FIGS. 2 and 4) formed by cutting out parts of the flange 113. The plurality of notches 114 are arranged at equal intervals in the left-right direction. Providing a plurality of notches 114 makes it possible to change the mounting position of the exercise device for small animals 1, which will be described later. In this embodiment, the notches 114 are provided at the upper end of the rear wall 112b of the peripheral wall 112, but this is not limiting. For example, the notches 114 may be provided at the upper end of the side wall 112c or the front wall 112d of the peripheral wall 112.

[0013] The front wall member 12 includes a front connecting portion 121 that connects the pair of side wall members 13, a pair of door portions 122, 122, and a locking portion 123 that locks the pair of door portions 122, 122 so that they cannot be opened. The front connecting portion 121 is provided on the lower side of the front wall member 12 and is formed in a rod shape that extends in the left-right direction. The pair of door portions 122, 122 are provided above the front connecting portion 121 and are configured to be able to swing forward like a double door. A glass plate 122a is used for the door portion 122. Note that the front wall member 12 may be configured without the front connecting portion 121.

[0014] 1 and 2, the side wall member 13 is provided with a plurality of air vents 131, an attachment hole 132 to which a water supply device (not shown) can be attached, and a joint portion 133 for connecting to the bottom wall member 11. The plurality of air vents 131 are circular holes and are provided on the rear side of the side wall member 13. The attachment hole 132 is an elongated hole whose width and length are greater than the diameter of the air vents 131 and is provided on the front side of the air vents 131. The joint portion 133 is provided in the lower center in the longitudinal direction (front-to-rear direction) of the side wall member 13 and is configured to be able to engage with a protrusion 112a provided on the peripheral wall 112 of the bottom wall member 11.

[0015] As shown in FIG. 4, the rear wall member 14 includes a rear connecting portion 141 that connects the pair of side wall members 13, and an upper wall portion 142 that is disposed above the rear connecting portion 141. The rear connecting portion 141 is formed with a generally H-shaped cross section, and the upper wall portion 142 is fitted above the rear connecting portion 141. The upper wall portion 142 is, for example, a glass plate. In this embodiment, the rear connecting portion 141 and the upper wall portion 142 are separate bodies, but they may also be integrated. Furthermore, the rear wall member 14 may not include the rear connecting portion 141.

[0016] As shown in FIGS. 1 and 2, the cover member 15 has a plurality of air vents 151 and a plurality of (four in this embodiment) recesses 152 into which the legs of another breeding container can be fitted. The plurality of air vents 151 are holes of the same shape as the air vents 131 of the side wall member 13, and are provided on the front side of the cover member 15. The recesses 152 are circular recesses with a diameter slightly larger than the outer diameter of the legs 111. The plurality of recesses 152 are provided at positions into which the legs 111 can be fitted. Providing the recesses 152 allows another breeding container to be placed stably on top of the breeding container 10.

[0017] The lid member 15 is attached to the pair of side wall members 13 with rivets 16. With the above configuration, the front wall member 12, the pair of side wall members 13, the rear wall member 14, and the lid member 15 can be removed from the bottom wall member 11 while still integrated, as shown in Figure 2. This allows the members 12 to 15 to be removed from the bottom wall member 11 without disassembling them, making it easier to clean the inside of the breeding container 10.

[0018] As shown in Figures 2 and 4, the breeding container 10 is equipped with an exercise device for small animals 1 (hereinafter simply referred to as "exercise device 1") for exercising small animals. The exercise device 1 is configured to be attachable to the inside of the breeding container 10. In this embodiment, the exercise device 1 is attached to the peripheral wall 112 of the bottom wall member 11, but is not limited to this. For example, the exercise device 1 may be configured to be attachable to the front wall member 12, the side wall member 13, or the rear wall member 14.

[0019] Fig. 5 is an exploded perspective view of the exercise device 1, and Fig. 6 is an enlarged view of the central longitudinal section of the exercise device 1. As shown in Figs. 5 and 6, the exercise device 1 includes a rotating wheel 2, a bearing holder 3, a bearing 4, a cap member 5, and a shaft member 6.

[0020] The rotating wheel 2 rotates in accordance with the running movement of the small animal. The rotating wheel 2 has an opening 20 formed on the front side, through which the small animal can enter the rotating wheel 2. The rotating wheel 2 has a large diameter portion 21 in which the opening 20 is formed, and a small diameter portion 22 provided on the rear side of the large diameter portion 21 (opposite the opening 20). The large diameter portion 21 and the small diameter portion 22 are integrally formed, for example, from a transparent resin. The center of the large diameter portion 21 coincides with the center of the small diameter portion 22.

[0021] The diameter of the large diameter portion 21 gradually increases as it approaches the opening 20. A plurality of protrusions 23 extending linearly along the axial direction of the rotating wheel 2 are provided on the inner wall surface of the large diameter portion 21. The plurality of protrusions 23 are arranged at equal intervals along the circumferential direction of the large diameter portion 21.

[0022] Small diameter portion 22 is formed as a recess when viewed from the front, and cap member 5 and other components are housed in this space. The depth of small diameter portion 22 and the height of cap member 5 are set so that cap member 5 does not protrude from small diameter portion 22 toward large diameter portion 21. In other words, when a small animal rotates wheel 2 to exercise, components such as cap member 5 do not get in the way.

[0023] The bearing holder 3 is installed from the rear side of the rotating wheel 2. The bearing holder 3 has a flat portion 30 and a cylindrical portion 31 integrally formed from resin. The flat portion 30 is formed in the shape of a circular plate. A through hole 32 is provided in the center of the flat portion 30, and a shaft 62 of the shaft member 6 (described later) is inserted into the through hole 32.

[0024] A male thread 33 is provided on the outer periphery of the cylindrical portion 31. A housing portion 34 for attaching the bearing 4 is provided inside the cylindrical portion 31. A plurality of protrusions 35 (see FIG. 5) are provided on the inner wall surface of the housing portion 34 (cylindrical portion 31). The protrusions 35 extend along the axial direction of the rotating wheel 2. The plurality of protrusions 35 are arranged at equal intervals along the circumferential direction of the cylindrical portion 31.

[0025] When the bearing 4 is inserted (housed) in the housing portion 34, it is pressed against the protrusions 35. This allows the bearing 4 to be press-fitted and fixed in the housing portion 34. The number, shape, and protrusion amount of the protrusions 35 are appropriately set taking into consideration the ease of the press-fitting operation and the mounting strength. The bearing 4 is, for example, a ball bearing.

[0026] A pair of positioning protrusions 36 are provided on the front side of the flat portion 30. A through hole 24 (see Figure 6) is provided in the small diameter portion 22 of the rotating wheel 2 for inserting the cylindrical portion 31, and this through hole 24 is provided with a positioning recess 25 that fits into the positioning protrusions 36. This makes it possible to prevent the bearing holder 3 from rotating unintentionally when the bearing holder 3 is assembled into the rotating wheel 2.

[0027] The cap member 5 is used to fix the bearing holder 3 to the rotating wheel 2. The cap member 5 is assembled from the front side of the rotating wheel 2. As shown in FIG. 6 , the cap member 5 includes a first cylindrical portion 50 and a second cylindrical portion 51 provided inside the first cylindrical portion 50.

[0028] An internal thread 52 is provided on the inner surface of the first cylindrical portion 50. The bearing holder 3 and the cap member 5 can be attached to the rotating ring 2 by threading the internal thread 52 into the external thread 33 of the bearing holder 3. The tip of the second cylindrical portion 51 abuts against the surface of the bearing 4 when the cap member 5 is attached to the rotating ring 2. This prevents the bearing 4 from accidentally moving in the axial direction of the rotating ring 2.

[0029] 5 and 6, the shaft member 6 includes a knob portion 60, a flat portion 61, and a shaft 62. The knob portion 60, the flat portion 61, and the shaft 62 are integrally formed from resin.

[0030] The knob portion 60 is formed in an elongated shape so that it can be easily gripped by hand. The flat portion 61 is formed in a circular plate shape. A gap is provided between the knob portion 60 and the flat portion 61, and the width of the gap is set to be slightly smaller than the thickness of a front wall 70 of the mounting member 7, which will be described later. This allows the knob portion 60 to be held to the front wall 70 by frictional force.

[0031] The shaft 62 is press-fitted into the inner ring of the bearing 4. A large diameter portion 621 is provided on the outer periphery of the shaft 62. The large diameter portion 621 is set to be slightly larger than the inner diameter of the inner ring of the bearing 4.

[0032] Fig. 7 is a rear perspective view of the exercise device 1. As shown in Figs. 5 to 7, the exercise device 1 is provided with an attachment member 7 for attaching the rotating wheel 2 to the rearing container 10 (see Figs. 1 to 4). The attachment member 7 is made of, for example, resin and has a generally T-shape when viewed from the front. When attached to the rearing container 10, the attachment member 7 is located between the rotating wheel 2 and the rearing container 10.

[0033] The mounting member 7 includes a front wall 70 erected on the rotating wheel 2 side (front side), and a side wall 71 horizontally extending from the periphery of the front wall 70 on the side opposite the rotating wheel 2 (hereinafter also referred to as the "anti-rotating wheel side"). In this embodiment, the anti-rotating wheel side refers to the rear side. The front wall 70 and the side wall 71 form the mounting member 7 in a container shape, and the anti-rotating wheel side of the mounting member 7 is open.

[0034] The front wall 70 is made up of, for example, a wide portion 701 and a narrow portion 702. The wide portion 701 is provided above the narrow portion 702, and the front wall 70 is generally T-shaped with the wide portion 701 and the narrow portion 702. The upper portion of the wide portion 701 (side wall 71) is formed in a semicircular shape.

[0035] The wide portion 701 has an inclined portion 701a that slopes upward toward the side opposite to the rotating wheel. The inclined portion 701a has an elongated hole 701b that extends in the vertical direction. By inserting the knob portion 60 of the shaft member 6 into the elongated hole 701b and rotating it, the knob portion 60 is held by friction on the front wall 70 (the inclined portion 701a), and the rotating wheel 2 can be attached to the attachment member 7. Furthermore, by providing the elongated hole 701b in the inclined portion 701a, the axis of the rotating wheel 2 can be inclined with respect to the horizontal direction.

[0036] The lateral wall 71 extends continuously along the periphery of the front wall 70. The lateral wall 71 is composed of, for example, a first lateral wall portion 711 extending laterally from the periphery of the wide portion 701, and a second lateral wall portion 712 extending laterally from the periphery of the narrow portion 702. The length L1 (see FIG. 6) of the first lateral wall portion 711 in the front-to-rear direction gradually decreases upward.

[0037] The end surface 712a of the second lateral wall portion 712 is inclined downward toward the rotating wheel 2 (front side). The length L2 (see FIG. 6) of the second lateral wall portion 712 in the front-to-rear direction gradually decreases downward. The inclination angle of the end surface 712a of the second lateral wall portion 712 is appropriately set depending on the inclination angle of the peripheral wall 112 of the bottom wall member 11 shown in FIG.

[0038] The mounting member 7 has a locking portion 72 provided on the side opposite the rotating wheel (rear side) from the side wall 71. The locking portion 72 is integrally formed with the front wall 70 and the side wall 71. FIG. 8 is an enlarged view of region VIII in FIG. 4. As shown in FIG. 8, the locking portion 72 is configured to be able to be locked to an upper portion of the first wall 17 of the breeding container 10. In this embodiment, the first wall 17 is the rear wall portion 112b, but is not limited to this. For example, the first wall 17 may be the side wall portion 112c or the front wall portion 112d of the peripheral wall 112 shown in FIG. 1.

[0039] In this embodiment, the locking portion 72 is provided at two locations (see FIG. 7) on the lower part of the first lateral wall portion 711, i.e., two (plural) locking portions 72 are provided, but this is not limited thereto. For example, only one locking portion 72 may be provided.

[0040] The locking portion 72 is formed, for example, in the shape of a hook. Specifically, the locking portion 72 is composed of an extension portion 721 extending from the side wall 71 toward the opposite side to the rotating wheel, and a hanging portion 722 hanging (extending) downward from the tip of the extension portion 721. The exercise apparatus 1 can be attached to the breeding container 10 by locking the extension portion 721 and the hanging portion 722 to the first wall 17 and bringing the end surface 712a of the second side wall portion 712 into contact with the first wall 17. Note that the locking portion 72 may be formed, for example, in a shape that can be fitted into the upper part of the first wall 17.

[0041] It is preferable that the upper part of first wall 17 is provided with folded portion 171 that is folded downward from the upper part of first wall 17. By providing folded portion 171, the contact area between first wall 17 and engaging portion 72 can be increased, thereby improving the mounting stability of exercise apparatus 1. When mounting member 7 is attached to breeding container 10, the lower end surface of folded portion 171 is substantially flush with the lower end surface of hanging portion 722.

[0042] The mounting member 7 includes a first contact portion 73 and a second contact portion 74 that contact the lower portion of a second wall 18 of the breeding container 10, which is provided above the first wall 17. Specifically, the second wall 18 includes a first standing wall 181 and a second standing wall 182 that is provided on the side opposite the rotating wheel (rear side) from the first standing wall 181. The first standing wall 181 contacts the first contact portion 73, and the second standing wall 182 contacts the second contact portion 74. In this embodiment, the second wall 18 is the rear connecting portion 141, but is not limited thereto. For example, the second wall 18 may be the front connecting portion 121 of the front wall member 12 or the side wall member 13 shown in FIG. 1 . In this embodiment, the second standing wall 182 is provided at a position separated from the first standing wall 181 (formed separately), but is not limited thereto. For example, the second standing wall 182 may be formed integrally with the first standing wall 181.

[0043] The second contact portion 74 is provided at a position away from the first contact portion 73 on the opposite side (rear side) of the rotating wheel. With this configuration, the first contact portion 73 and the second contact portion 74 are brought into contact with the second wall 18, so that the locking portion 72, which is locked to the first wall 17 of the breeding container 10, can be held down at at least two points. This improves the mounting stability of the mounting member 7 and reduces rattling of the mounting member 7 when the small animal rotates the rotating wheel 2.

[0044] The second contact portion 74 is preferably provided below the first contact portion 73. That is, the second standing wall 182 preferably protrudes below the first standing wall 181. This configuration improves the mounting stability of the mounting member 7 and further reduces rattle of the mounting member 7 when the rotating wheel 2 is rotated, compared to when the first contact portion 73 and the second contact portion 74 are provided at the same height. In this embodiment, the vertical distance D1 between the first contact portion 73 and the second contact portion 74 is substantially the same as the thickness T1 of the first contact portion 73 (including ±10% of the thickness T1), but is not limited thereto. For example, the distance D1 may be greater or smaller than the thickness T1. Furthermore, the second contact portion 74 is not limited to the above, and may be provided at the same height as the first contact portion 73.

[0045] It is preferable that the first contact portion 73 is provided on the locking portion 72, and the second contact portion 74 is provided on the side opposite to the rotating wheel (rearward) from the locking portion 72. With this configuration, the first contact portion 73 and the second contact portion 74 can be spaced apart more than when both the first contact portion 73 and the second contact portion 74 are provided on the locking portion 72, which increases the mounting stability of the mounting member 7 and further reduces rattling of the mounting member 7 when the rotating wheel 2 is rotated.

[0046] In this embodiment, the first abutment portion 73 is an extension portion 721, and the second abutment portion 74 is a protrusion that protrudes from the side (rear surface) of the upright portion 722 opposite the rotating wheel. The second abutment portion 74 extends along the width direction (left-right direction) of the mounting member 7. The second abutment portion 74 is provided above the lower end surface of the upright portion 722. The thickness of the second abutment portion 74 is substantially the same as the thickness T1 of the first abutment portion 73. Note that the first abutment portion 73 and the second abutment portion 74 are not limited to the above. For example, the first abutment portion 73 and the second abutment portion 74 may be steps provided on the extension portion 721.

[0047] It is preferable that the locking portion 72 can be fitted into the notch 114 of the bottom wall member 11 shown in Fig. 2. Such a configuration can prevent the exercise device 1 from rattling in the width direction (left and right direction) relative to the breeding container 10. In this embodiment, the notch 114 is provided in the upper part of the first wall 17, but it may also be provided in the lower part of the second wall 18.

[0048] [1] As described above, the small animal exercise device 1 of this embodiment comprises a rotating wheel 2 that rotates in response to the running movement of the small animal, and an attachment member 7 for attaching the rotating wheel 2 to the rearing container 10, and the attachment member 7 comprises an engagement portion 72 that can be engaged with the upper part of the first wall 17 of the rearing container 10, and a first abutment portion 73 and a second abutment portion 74 that abut against the lower part of the second wall 18 of the rearing container 10 provided above the first wall 17, and the second abutment portion 74 is provided at a position away from the first abutment portion 73 on the opposite side of the rotating wheel 2 (the anti-rotating wheel side).

[0049] According to this configuration, the first contact portion 73 and the second contact portion 74 are brought into contact with the second wall 18, so that the locking portion 72, which is locked to the first wall 17 of the breeding container 10, can be held down at at least two points. This improves the mounting stability of the mounting member 7, and prevents the mounting member 7 from rattling when the rotating wheel 2 is rotated.

[0050] [2] In the exercise device for small animals 1 described above in [1], the second contact portion 74 is preferably provided below the first contact portion 73.

[0051] With this configuration, the mounting stability of the mounting member 7 is improved compared to when the first abutment portion 73 and the second abutment portion 74 are provided at the same height, and rattling of the mounting member 7 when the rotating wheel 2 is rotated can be further suppressed.

[0052] [3] In addition, in the small animal exercise device 1 of [1] or [2] above, it is preferable that the first abutment portion 73 is provided on the locking portion 72, and the second abutment portion 74 is provided on the opposite side (rear side) of the rotating wheel from the locking portion 72.

[0053] With this configuration, the first abutment portion 73 and the second abutment portion 74 can be spaced apart compared to when both the first abutment portion 73 and the second abutment portion 74 are provided on the locking portion 72, thereby increasing the mounting stability of the mounting member 7 and further suppressing rattling of the mounting member 7 when the rotating wheel 2 is rotated.

[0054] [4] Furthermore, it is preferable that the breeding container 10 is equipped with any one of the small animal exercise devices 1 described above [1] to [3], and that the upper part of the first wall 17 or the lower part of the second wall 18 has a notch 114 into which the engaging part 72 can be fitted.

[0055] With this configuration, it is possible to prevent the exercise device for small animals 1 from rattling in the width direction (left and right direction) relative to the breeding container 10.

[0056] The exercise equipment for small animals and the rearing container are not limited to the configuration of the above-mentioned embodiment, nor are they limited to the above-mentioned effects. Of course, the exercise equipment for small animals and the rearing container can be modified in various ways without departing from the spirit of the present invention. [Explanation of symbols]
