The connection holes 26a and 26b may be formed directly at the longitudinal ends of the first member 23a and the second member 23b. As shown in FIG. 5, the first member 23a and the second member 213 are formed. It may be formed on a separate cap-shaped connecting member fitted to the longitudinal end of the.

  In the present embodiment, the upper frame 21 and the lower frame 23 are arranged along a horizontal plane, respectively. However, by arranging the upper frame 21 and the lower frame 23 along other planes (for example, a vertical plane), for example, a linear shape as a side member. You may comprise so that the horizontal direction edge part of the member 30 may be connected with a frame (a 1st frame and a 2nd frame).

  The upper frame 21 and the lower frame 23 are provided with recesses 21c and 23c for receiving the fixing member 40. The recesses 21c and 23c are provided at positions corresponding to each other when the frame body 20 is assembled. That is, the concave portions 21c and 23c are arranged at corresponding positions so that the linear member 30 extends in the vertical direction when both ends of the linear member 30 are pushed into the concave portions 21c and 23c via the fixing member 40, respectively. The

  The linear member (side member) 30 supported by the upper frame 21 and the lower frame 23 is a columnar member formed of metal (for example, iron or stainless steel). As shown in FIG. 4A, the both end portions 30T of the linear member 30 are provided with recessed fitting grooves 33 along the circumferential direction at predetermined positions separated from the tip by a predetermined length. The position (predetermined position) where the fitting groove 33 is provided is a position corresponding to the position of the fitting protrusion 43 of the fixing member 40 when the linear member 30 is pushed into the fixing member 40 deeply. Note that the outer diameter, the number, and the arrangement interval of the linear members 30 can be appropriately set according to the specifications of the pet circle. The linear member 30 may be hollow or solid, and may be a long plate. Here, FIG. 4A is a perspective view showing a state in which the linear member 30 according to the present embodiment is pushed into the recesses 21c and 23c via the fixing member 40, and FIG. FIG. 1C is a cross-sectional view in the vertical direction (the vertical direction in FIGS. 1 to 3) showing the configuration of the linear member 30 and the fixing member 40, and FIG. FIG.

  As shown in FIG. 4, the fixing member 40 into which the end portion 30 </ b> T of the linear member 30 is pushed is a hollow substantially cylindrical member. The fixing member 40 is formed by, for example, molding with ABS resin, iron, polypropylene, or rubber, or die casting (press-fit) of aluminum or zinc alloy, and the shape thereof may penetrate as shown in FIG. However, a bottomed structure may be used.

  On the outer surface of the fixing member 40, a protrusion 41 protruding outward is provided along the circumferential direction. The protrusion 41 is formed so that the outer diameter increases from one end disposed at the back side of the recesses 21c and 23c to the other end of both ends in the longitudinal direction. A plurality of the protrusions 41 are provided in the longitudinal direction of the fixing member 40. In addition, the protrusion 41 can employ | adopt arbitrary shapes suitably, if it can be hold | maintained by the recessed parts 21c and 23c, for example, can also be made hemispherical.

  On the inner surface of the fixing member 40, a fitting protrusion 43 protruding inward is provided along the circumferential direction. The position where the fitting protrusion 43 is provided in the fixing member 40 is such that when the fixing member 40 is pushed into the recesses 21c and 23c, the fitting protrusion 43 is in the recesses 21c and 23c.

  When the fixing member 40 configured as described above is pushed into the recesses 21c and 23c, the fixing member 40 is held in a state of being prevented from being detached from the recesses 21c and 23c due to friction between the recesses 21c and 23c and the protrusion 41. Further, when the linear member 30 is pushed into the fixing member 40 held by the recesses 21c and 23c, first, the tip side portion of the end portion 30T comes into contact with the fitting protrusion 43. When the linear member 30 is further pushed into the fixing member 40 from this state, the end 30T advances to the back side while expanding the fitting protrusion 43, and when the tip of the end 30T reaches the deepest, the end 30T is fitted. The fitting protrusion 43 is inserted into the mating groove 33. The fitting groove 33 and the fitting projection 43 are thus fitted to each other, whereby the linear member 30 is prevented from being detached from the fixing member 40 and fixed. When the above steps are performed on all the linear members 30, as shown in FIGS. 2 and 3, the linear members 30 are transferred from the upper frame 21 to the lower frame 23 or from the lower frame 23 to the upper frame 21. Is in an extended state. When the fixing member 40 is constituted by a member having elasticity, the contact area with the inner surfaces of the recesses 21c and 23c is increased and strongly held by the elastic force, and the linear member 30 is also fixed. It receives a strong elastic force from 40 and is held more securely.

  Instead of the linear member 30 and the fixing member 40, a columnar linear member 130 and a substantially cylindrical fixing member 140 as shown in FIG. 4C may be used. In the linear member 130, the fitting protrusion 133 is provided in the end part 130T along the circumferential direction. In the fixing member 140, a protrusion 141 is formed on the outer surface in the same manner as the protrusion 41 of the fixing member 40. Furthermore, a fitting groove 143 into which the fitting protrusion 133 is fitted is recessed in the inner surface of the fixing member 140 along the circumferential direction. Similar to the linear member 30 and the fixing member 40, the linear member 130 and the fixing member 140 are fixed to each other, and the fixing member 140 is held in the recesses 21c and 23c. In other words, the linear member 130 is pushed into the fixing member 140, and the fitting protrusion 133 is fitted into the fitting groove 143 when the end of the end portion 130T reaches the innermost position. Thus, the fitting member 133 and the fitting groove 143 are fitted to each other, whereby the linear member 130 is prevented from being detached from the fixing member 140 and fixed.

  As shown in FIGS. 2 and 3, the upper frame 21 and the lower frame 23 holding the linear member 30 are assembled from the upper side of the upper frame 21 in a state where the ends are assembled together so as to form a rectangular shape. The support member 25 is inserted into the coupling holes 24a, 24b, 26a, and 26b (FIG. 5), and can be assembled in a cage shape. Here, FIG. 5 is a perspective view showing a state in which the support member 25 is inserted into the first members 21a and 23a and the second members 21b and 23b according to the present embodiment.

  Note that the fixing member 40 only needs to be pushed into at least one of the corresponding recesses 21c and 23c, and the other recess when the fixing member 40 is held only in one of the fixing members 40 is not connected to the fixing member 40. The shape member 30 may be inserted.

  Next, the door body 35 for the pet to enter and exit will be described with reference to FIGS. 1, 3, and 6. Here, FIG. 6 is a diagram showing the relationship between the door body 35 according to the present embodiment, the linear member 30, the upper frame 21, and the lower frame 23, where (a) is a side view and (b). Is a cross-sectional view taken along the line VIB-VIB in FIG. 3, and FIG. 5C is a cross-sectional view taken along the line VIC-VIC in FIG. The door body 35 is of a sliding door type that is slidable along a side surface constituted by a plurality of linear members 30.

  In the conventional pet circle, the door of the outward opening or the inward opening was provided as an entrance of a pet. However, in such a door structure, in order to allow the door to be opened and closed, it is necessary to provide a space in front of the door in the case of opening outward and inside the door in the case of opening inward. In particular, in the case of outward opening, when the pet in the pet circle collides with the door, the door may open due to the impact. In view of such a problem, in the present embodiment according to the present invention, a sliding door type door body 35 is provided. This eliminates the need for a large space for opening and closing the door. Even if the pet collides with the door body 35, the collision direction and the moving direction of the sliding door are orthogonal to each other, so that the door can be prevented from being opened by an impact.

  On the other hand, in sliding door type doors used in fields other than pet circles, guide grooves for guiding the opening and closing of the sliding doors are provided vertically, and the doors are opened and closed while sliding in the grooves. However, the lower one of the guide grooves tends to collect dust and other dust as the door is used, and the sliding door cannot be opened and closed smoothly. Further, when a sliding door type door using such a guide groove is used for a pet circle, foreign matter from manure and other pets in addition to dust tends to collect in the guide groove, and the pet circle may become unsanitary. On the other hand, in the present embodiment according to the present invention, the upper end of the door body 35 is locked to the side member 30 (particularly the auxiliary member 31) and the lower part of the door body 35 (particularly the second side of the regulating member 36). 36b) is configured to enter between the parallel linear auxiliary members (particularly the second auxiliary member 38) provided in the horizontal direction of the side member. Accordingly, since at least the lower guide groove is not provided, it is possible to prevent uncleanliness due to accumulation of excrement and other foreign matters.

  The door body 35 is connected to the plurality of linear portions 35b extending along the extending direction of the linear member 30 and the upper ends of the plurality of linear portions 35b so as to be orthogonal to the linear portions 35b. The part 35a and the 2nd connection part 35c which connects the lower end of the several linear part 35b so that it may orthogonally cross with the linear part 35b are provided.

  As shown in FIGS. 3, 4 (a) and 4 (b), a bar-shaped auxiliary member 31 made of the same material as the linear member 30 is welded to the upper portion of the linear member 30 so as to be orthogonal to the linear member 30. Has been. One end of a guide member 32 having a substantially L-shaped side surface is welded to the auxiliary member 31. The guide member 32 is bent substantially at the center in a side view and directed in a direction along the linear member 30, and the guide portion 32 a at the tip thereof is further bent and extends in a direction parallel to the auxiliary member 31. On the side surface of the guide portion 32a, a fitting groove 33 is placed so as to be slidable on the guide portion 32a. The fitting groove 33 is arranged on the outer side, and is held on the inner surface of a U-shaped clamping member 34 that is open in a side view in a side view. On the other hand, inside the pinching member 34, the connecting portion 35 a of the door body 35 is locked to the fitting groove 33, and the connecting portion 35 a is held by the pinching member 34 and the fitting groove 33. With such a configuration, the door body 35 in which the coupling portion 35a is sandwiched between the fitting groove 33 and the sandwiching member 34 that move together on the guide portion 32a extending in the direction orthogonal to the linear member 30 is guided. The sliding movement along the portion 32a is possible, and the door body 35 is thereby opened and closed.

  On the other hand, as shown in FIGS. 3, 4A, and 4C, a second rod-like member made of the same material as that of the linear member 30 is provided in the lower portion of the linear member 30 in parallel to the auxiliary member 31 and the guide portion 32a. Two auxiliary members 38 are welded in parallel (see FIG. 5). A substantially inverted L-shaped regulating member 36 is welded to the second connecting portion 35c of the door body 35 so as to intersect the second connecting portion 35c. More specifically, the regulating member 36 includes a first side 36a extending substantially horizontally in a direction approaching the linear member 30, and a second side 36b substantially parallel to the linear member 30 substantially perpendicularly from the first side. The first side is welded to the second connecting portion 35c, and the second side 36b enters between the two second auxiliary members 38 from above. Accordingly, since the lower part of the door body 35 (the second side 36b of the regulating member 36) slides between the two second auxiliary members 38, a smooth opening / closing operation of the door body 35 can be realized.

  In addition, on the second side 36b of the restricting member 36, a support member 37 having an inverted T-shape in a side view from the lower side of the second auxiliary member 38 is attached to at least one place. The support member 37 includes a disc-shaped base portion 37a and a cylindrical portion 37b extending from the center portion of the base portion 37a, and the cylindrical portion 37b is attached to the second side 36b of the regulating member 36, and further, a disc-like shape. The base portion 37a is in contact with the lower side of the two second auxiliary members 38. Accordingly, the door body 35 can be opened and closed more smoothly because it slides between the two second auxiliary members 38 while preventing rattling.

  According to the present embodiment, the lower portion of the door body 35 (the second side 36b of the regulating member 36) slides between the two second auxiliary members 38, so that it is necessary to provide a guide groove for guiding the door body 35. Crying, pet manure and other foreign matter are less likely to collect, and even if the door body 35 swings up and down due to the opening and closing operation, the restricting member 36 restricts the upward swing of the second connecting portion 35c. The opening / closing operation can be realized.

  Moreover, the door body 35 is provided with the lock mechanism 50 shown in FIG.1, FIG7 and FIG.8. FIG. 7 is a perspective view showing the configuration of the lock mechanism 50 according to the present embodiment. 8A is a cross-sectional view taken along line VIIIA-VIIIA in FIG. 7 showing the configuration of the lock mechanism 50 in a natural state, and FIG. 8B shows the configuration of the lock mechanism in a state where a load is applied to the holding member 51. FIG. 8C is a cross-sectional view taken along line VIIIA-VIIIA in FIG. 7, and FIG. 8C is a cross-sectional view taken along line VIIIC-VIIIC in FIG. 7 showing the configuration of the lock mechanism in the natural state.

  The locking mechanism 50 includes a rotating member 51 into which the outermost two linear portions 35b1 and 35b2 (FIG. 3) among the plurality of linear portions 35b are inserted, and the rotating member 51. A holding member 55 that can select locking and unlocking of an arbitrary linear member 30a (the outermost linear member in FIGS. 1 and 3) among the plurality of linear members 30 is provided. The holding member 55 is disposed in a housing portion 51 a that is recessed in the center of the rotation member 51, and rotates around a rotation shaft 62 (FIG. 8) fixed to the rotation member 51. The rotation member 51 is provided with through holes 52 and 53 through which the linear portions 35b1 and 35b2 are inserted along a direction parallel to the rotation shaft 62.

  One end of the main body plane 57 of the holding member 55 is provided with an operation portion 56 that protrudes upward (in a direction away from the rotation member 51) from the main body plane 57, and the other end once protrudes downward and then the operation portion. A linear member locking portion 58 bent toward the 56 side is provided. The rotation shaft 62 is at a substantially intermediate position between the operation portion 56 and the linear member locking portion 58 in the horizontal direction. An elastic member 60 (plate spring) that urges the holding member 55 is disposed between the operation unit 56 and the bottom surface 54 of the accommodating unit 51a so that the main body plane 57 and the bottom surface 54 are parallel to each other.

  In the lock mechanism 50 configured as described above, the outer linear member 30a is locked and held between the linear member locking portion 58 and the rotating member 51 in a natural state where no force is applied to the operation portion 56. . Since the linear portions 35b1 and 35b2 of the door body 35 are always held by the rotating member 51, the linear member 30 and the door body 35 are in a locked state (FIGS. 8A and 8C). . On the other hand, when the operating portion 56 is pushed so as to approach the rotating member 51, the holding member 55 rotates around the rotating shaft 62 (in the direction of the arrow in FIG. 8A), and the linear member is locked. Since the portion 58 moves upward and separates from the holding member 55, the locking of the outer linear member 30 a by the linear member locking portion 58 is released, and the outer linear member 30 a is released from the lock mechanism 50. Thereby, the locked state of the linear member 30 and the door body 35 is cancelled | released, and the door body 35 will be in the state which can be opened and closed. Here, when the force applied to the operation unit 56 is reduced to zero, the holding member 55 returns to a natural state in which the main body flat surface 57 and the bottom surface 54 are parallel by the elastic force of the elastic member 60. At this time, if the outer linear member 30a is held between the linear member locking portion 58 and the rotating member 51, the outer linear member 30a returns to the locked state, and the outer linear member 30a is locked to the linear member. When it is left in a state of being detached from the part 58, the unlocked state is maintained.

  Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention. For example, in the above-described embodiment, a linear member is adopted as the side member. However, since it is only necessary that a part of the side member is pushed into the fixing member and is fixed, the entire surface is substantially planar and has four corners. Protruding portions may be provided so that the protruding portions are pushed into and fixed to the fixing member, and the side members other than the linear members can be appropriately adopted.
