Description

  The present invention relates to a sandbox facility that prevents animals such as cats from entering the sandbox and keeps the sandbox hygienic.

Nursery and kindergarten sandboxes may be contaminated by excrement of animals such as small animals. Such contamination is sometimes overlooked, and there is a lack of consideration for children's hygiene. In response to this situation, the sandbox managers have regularly replaced sand in the sandbox and covered the sandbox with sheets when the sandbox is not in use. However, such work is labor intensive and not easy.
Utility Model Registration No. 3069379 discloses a sandbox protective net for preventing cats and dogs from entering. This sandbox protective net is described in that a net is attached so as to surround the sandbox on a support column provided upright around the sandbox. The net is provided with a hanging portion whose lower end hangs outward from the ground around the sandbox, and a bent portion that is bent outward is formed at the upper end of the support column. It is described that an outward return portion is provided at the upper end of the. However, this net is attached by means such as passing the ring provided on the net through the support, and the bottom of the net is lifted to allow children to enter and exit, so the sandbox is always surrounded by the net. The feeling of opening was poor.
Japanese Laid-Open Patent Publication No. 2002-176902 discloses a sandbox protection device including a plurality of winding doors provided so as to surround a sandbox. This sandbox protection device is provided with a winding door around the sandbox, thereby blocking the sandbox only when it is not necessary to open it. However, such a large-scale apparatus has a problem that the cost for installing it is increased.

If the sandbox is always surrounded by the net, it will be a sandbox with little openness. Moreover, if a large-scale apparatus is provided in the sandbox, the cost for installing it will increase. In view of such problems, the present invention is to reliably prevent the invasion of dogs and cats and to maintain a sanitary sandbox, and has a simple structure. It is to provide facilities for sandboxes so that effective effects can be obtained.

The small animal intrusion prevention equipment of the present invention is a sandbox facility that prevents small animals such as dogs and cats from entering the sandbox by stretching walls around the sandbox,
A post provided adjacent to Sand, a support member provided by the support to the strut, is formed by the width between adjacent struts, hung to the support member, and the linear member along the lower edge The net is provided with a locking means for engaging each other at adjacent side ends . Further, a hook is provided at a lower portion of the support column, and a lower ring is provided at both end portions of the linear member, so that the lower ring can be locked to the hook .

The invasion prevention equipment for small animals of the present invention is provided such that a support member such as a rope is supported by a support provided in a sandbox and a support, such as a rope, and a net suspended from the support member is provided to stretch a wall around the sandbox. Therefore, it is possible to keep a sanitary sandbox by preventing the invasion of small animals such as dogs and cats while having a simple structure. And since the net | network is formed in the width | variety between adjacent support | pillars, the sandbox can be opened only by opening and closing the net | network between support | pillars. Further, by providing a linear member (chain or wire) along the lower edge of the net , it is possible to provide an intrusion prevention facility that prevents small animals such as dogs and cats from entering the sandbox from the lower end of the net . In order to stretch the wall around the sandbox without any gaps, it is only necessary to lock the nets adjacent to each other with locking means that engage with each other, thereby constructing a small animal intrusion prevention facility with a simple structure. Is done.
The linear member provided at the lower edge of the net is provided with a lower ring so that it can be locked to the hook provided on the support post so that the lower edge of the net does not rise on windy days. . Thereby, the entrance and exit of small animals such as dogs and cats can be more reliably prevented.

  1 and 2 show a small animal intrusion prevention apparatus 10 according to the present invention, which is in a state where a sandbox is blocked or opened, respectively. This small animal intrusion prevention equipment 10 is generally composed of a support column 1 provided outside the corner of the sandbox, a wire 2 (support member) provided between the support columns 1, and a net 3 ( Wall member). The net 3 is a net made by knitting a bundle of fibers, and a net having sufficient strength against attack by small animals such as dogs and cats and having weather resistance is used. The size of the net 3 is the length between the struts 1 that are adjacent to each other in width, and the height is high enough to prevent a dog or cat from jumping over (about 1.8 m). A net ring 5 is attached to the upper edge of the net 3 at an appropriate interval, and a linear member 6 (for example, a chain, a spiral wire, a thick string, rubber, etc., which will be described later) along the lower edge of the net 3. ) Is installed. As a result, small animals such as dogs and cats cannot enter the sandbox by diving at the lower edge of the net 3. Moreover, since the gap between the lower edge of the net 3 and the ground becomes difficult to be created due to wind or the like by setting the weight of the linear member 6 so as not to be blown by wind, the effect of preventing invasion of small animals can be obtained. improves.

  On the other hand, the column 1 standing on the outside of each corner of the sandbox 8 has a height of about 2 m, and a wire ring 4 for fixing the wire 2 is welded to the upper part. The wire 2 is fixed or locked by the wire ring 4. By the way, hooks are provided at both ends of the wire 2 so that the ring 4 can be freely engaged or disengaged, or the wire 2 is passed through the wire 4 and fixed after passing through the ring 5 for the net 3 of the net 3. Is done. In this way, the small animal intrusion prevention equipment 10 constructed by suspending the net 3 from the wire 2 via the net ring 5 can easily open and close the net 3 by hand.

  A pinch 7 is provided at the side end of the net 3, and the adjacent nets 3 are sandwiched and stopped by the pinch 7 so that no gap is formed between the adjacent nets 3. Thereby, a wall can be stretched around the sandbox 8 without a gap, and a small animal intrusion prevention facility is constructed with a simple structure. Further, the pinch 7 provided in this way can also be used when the net 3 is bundled in the vicinity of the support column 1. In addition, the pinch 7 can be provided in the support | pillar 1, or it can replace with the pinch 7 and can also provide latching means, such as a string.

  FIG. 3A is an explanatory view showing the left corner of the small animal intrusion prevention equipment 10 in order to explain another embodiment. As shown in FIG. 3A, a chain 6a (linear member) is provided on the lower edge of the net 3, and a hook 4a is welded to the lower portion of the support column 1 in order to lock the chain 6a. Provided. Then, by locking the chain 6a to the hook 4a, the lower end of the net 3 is prevented from flying up by the wind, which helps to prevent the invasion of dogs and cats. When a member other than the chain 6a, for example, a thick string is provided on the net 3, a ring (lower ring) that can be locked to the hook 4a of the support column 1 may be provided at both ends of the thick string.

  FIG. 3B shows an intrusion prevention facility 10 in which the support column 1 is provided inside the net 3. In the case of the intrusion prevention equipment 10 having such a configuration, the mating portion of the adjacent net 3 (the side end portion of the net 3) has a structure supported by the support column 1, so that the influence of wind is further exerted. It becomes difficult. However, in this case, since the net 3 is not locked by the chain 6 a at the lower part of the support 1, a considerable force is applied to the joining portion of the adjacent nets 3. Therefore, in the case of the intrusion prevention equipment 10 of this form, it is not sufficient to simply hold the net 3 with the pinch 7, and it is preferable to use other locking means together.

  FIG. 3 (c) shows a state in which the bottom surface 3 a of the net 3 is attached to the ground by making the length of the net 3 sufficiently long with respect to the column 1. Thus, by providing the bottom surface 3a on the net 3, the effect of preventing the entry of small animals is further improved. That is, small animals such as dogs and cats cannot lift the bottom face 3a of the net 3 facing outward and can not enter, so that these small animals can be more reliably prevented from entering the sandbox.

  FIG. 4 illustrates the locking means other than the pinch 7 with respect to the locking means at the mating portion of the adjacent nets 3. These locking means are appropriately selected according to the surrounding environment and purpose, but when the fastener 11 is provided at the side end of the net 3 as shown in FIG. Since the nets 3 can be joined together with almost no gap, entry of small animals into the sandbox can be completely controlled. Incidentally, a hook-and-loop fastener (not shown) can be provided in place of the fastener 11 that engages the element with the slider.

  About the fastener 12 shown in FIG.4 (b), the structure and operation | movement are shown to FIG.4 (c) and FIG.4 (d). As shown in FIGS. 4B to 4D, the fastener 12 is provided with a rod-like member 13 at one side end of the net 3, and fitting members 12 a and 12 b for fitting the rod-like member 13 are connected to the other end of the net 3. It is provided at the side end portion. Thereby, the rod-shaped member 13 and fitting member 12a, 12b can be fitted, and the mutually adjacent net | network 3 can be hold | maintained in the closed state. Incidentally, the fitting member 12a of the fastener 12 shown in FIG. 4 (c) is formed by pivotally supporting two members having a crescent-shaped cross section and biasing each member inward by a spring. In the fastener 12 of this form, the rod-like member 13 is fitted into the fitting member 12a by inserting the rod-like member 13 through the opening against the urging force of the fitting member 12a. Similarly, the fastener 12 shown in FIG. 4 (d) is an elastic member in which the fitting member 12b is formed in a horseshoe shape in cross section, and the rod-like member 13 is held by pushing and opening the opening. .

  As described above, the small animal intrusion prevention facility 10 in which the width of the net 3 is the length between the adjacent struts 1 has been described, but the sandbox 8 may be surrounded by a single continuous net. FIG. 5 shows an intrusion prevention facility 20 in which a fixing member 15 is provided on the upper portion of the support 1 in accordance with the shape of the sandbox. The intrusion prevention equipment 20 further allows the fixing member 15 to carry the wire 2 and allows the net ring 5 to be inserted into the wire 2 so that the net ring 5 can move along the outer peripheral wall of the fixing member 15. It is a thing. That is, since the net 3 is attached to the net ring 5, the fastener 11 is opened and the net 3 is bundled, or as shown in FIG. 5, the net 3 is closed with the sandbox surrounded. It can be a sandbox facility that can prevent the invasion of dogs and cats.

  Although not shown in the drawings, as another form of intrusion prevention equipment, an engagement protrusion that is continuous with the outer peripheral wall of the fixing member 15 is provided, and a hook that engages with the engagement protrusion is provided on the net 3. Good. Thereby, since the hook can be slid on the engaging projection, the intrusion prevention equipment 20 can be opened and closed freely. Moreover, the member to be suspended is not limited to the net 3, and can be configured by suspending a plurality of cloth or plastic plate-like members having excellent weather resistance.

  To keep the sandbox hygienic, try to hit the sandbox as much as possible. However, when the children are playing or when the sun is too strong, a hook 9 (an awning member) as shown in FIG. Thereby, although it is a simple structure, the invasion prevention apparatus of the small animal which can prevent the invasion of the small animal of a dog or a cat and can maintain a sanitary sandbox can be constructed.
