Description

[Technical field]

[0001] The present invention relates to a fence for preventing pets from escaping. [Background technology]

[0002] When keeping pets (hereinafter also referred to as pets) indoors, a free-standing animal intrusion prevention fence may be installed indoors to prevent the pet from escaping from a specific location in each room, as shown in, for example, Patent Document 1. Such an animal intrusion prevention fence has a door that can be opened and closed freely and allows people to pass through. Also, to prevent the pet from escaping from each room to other places such as a hallway or entrance, a pet fence may be installed in place of the room door at the entrance / exit of a room that leads to the hallway or entrance, as shown in, for example, Patent Document 2.

[0003] Such a pet fence includes a vertical lattice fence body and a panel plate detachably attached to the upper part of the fence body. The above-mentioned fence body is installed so as to span between opposing wall surfaces that form the periphery of the entrance / exit of a room. The height dimension of the fence body from the floor surface and the width direction dimension are set to about 1450 mm to 1550 mm and 650 mm to 750 mm, respectively. The fence body includes an openable and closable door through which a person can pass. The door has a door locking mechanism at the upper end and the lower end of the fence body. The door locking mechanism maintains the door in a closed state by a latch mechanism, and when the door is closed, a handle provided on a horizontal member of the fence body is lifted straight up, and the door is opened by pulling it toward the back or toward the front.

[0004] The fence body is installed so as to span between the opposing wall surfaces that form the perimeter of the entrance / exit of a room, and tensioning mechanisms are provided at the upper and lower left and right ends of the fence body. Each tensioning mechanism is equipped with an installation bolt and a tightening nut that is screwed into the shaft of the installation bolt so that it can move forward and backward. The head of each installation bolt is directly abutted against the wall surface, and each tightening nut is tightened into the fence body, so that the fence body is held in a tensioned state between the wall surfaces, and is held between the wall surfaces at its four corners.

[0005] [Patent Document 1] JP 2013-128447 A [Patent Document 2] Utility model registration No. 3244905 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the pet fence shown in Patent Document 2, the door locking mechanism has a complex configuration requiring multiple latch mechanisms, and the weight of the fence body that can withstand a pet's body strike is relatively large, so it may not be easy for children and the elderly to lift the handle straight up to open and close the door and pull the door toward the back or toward the front. In addition, when the head of each installation bolt directly abuts against the wall surface, the contact area between the head of the installation bolt and the wall surface is relatively small, so the end face of the head of each installation bolt is not pressed parallel to the sliding wall surface, and the fence body may be held at an angle to the wall surface. In addition, there is a risk that a pet (cat) may climb over the pet fence by using the door crossbar with a handle provided on the cross member of the fence body as a foothold when the door is closed.

[0007] In consideration of the above problems, the object of the present invention is to provide a pet escape prevention fence which has a lock / unlock mechanism consisting of a simple door structure and can be easily and accurately installed between opposing wall surfaces which form the periphery of the entrance / exit of a room. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the pet escape prevention fence of the present invention comprises an end post supported via a plurality of fixing bolts on one of a pair of fixing posts arranged between opposing wall surfaces that form the periphery of the entrance or exit of a room, a door support member supported via a plurality of fixing bolts on the other of the pair of fixing posts and supporting a door so that it can be rotated, and a lock / unlock mechanism for locking the door relative to the end post so as to close it from inside or outside the room, or unlocking the door relative to the end post so as to open it, with the heads of the opposing fixing bolts each fitted into a recess in each pad having a lower surface that abuts against the opposing wall surface, and the heads of the opposing fixing bolts are each pressed against the wall surface to hold the end post and the door support member in place.

[0009] The lock / unlock mechanism may comprise a pair of striking members rotatably mounted on the door, a fixing pin connecting one end of the pair of striking members via a through hole in the end post of the door, and a receiving seat mounted on the end post for receiving and locking the other ends of the pair of striking members. The pad may be formed in a disk shape, have a recess in the center into which the head of the fixing bolt fits, and have a plurality of concentric grooves on the underside. The pad may be formed in an oval shape, have a recess in the center into which the head of the fixing bolt fits, and have a plurality of concentric oval grooves on the underside. Effect of the Invention

[0010] The pet escape prevention fence of the present invention is equipped with a lock / unlock mechanism that locks the door relative to the end post so that it can be closed from inside or outside the room, or unlocks the door relative to the end post so that it can be opened, and the heads of the opposing fixing bolts are pressed toward the wall surface while fitting into the recesses of each pad, which has a lower surface that abuts against the opposing wall surface, thereby holding the end post and door support member in place, so that the pet escape prevention fence can be easily and accurately installed between the opposing wall surfaces that form the periphery of the entrance / exit of a room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] FIG. 1 shows an example of a pet escape prevention fence according to the present invention installed between opposing wall surfaces that form the entrance / exit of a room.

[0013] The pet escape prevention fence (hereinafter also referred to as the fence) is composed of pads 25 and 26 (see Figures 3 and 4) described below on wall STB, of the opposing wall surfaces STA and STB that form the entrance / exit PA of the room, a fixing post 18 held by a fixing bolt 24, pads 25 and 26 (see Figures 3 and 4) described below on wall surface STB, a fixing post 20 held by a fixing bolt 24 on wall surface STA, a vertical lattice fence 14 that forms part of the right-hand side of the fence, a vertical lattice fence door 10 described below, a door support member 12 that rotatably supports the door 10, and a lock / unlock mechanism 34 that locks / unlocks the door 10 to the end post 16 of the vertical lattice fence 14 (see Figures 2(a) and (b)).

[0014] The fixing post 18 has female threaded holes at its upper and lower parts, into which the fixing bolts 24 are fitted. The fixing post 20 also has female threaded holes at its upper and lower parts, into which the fixing bolts 24 are fitted.

[0015] The vertical lattice fence 14 is composed of an upper rail 14U, a lower rail 14L, a number of small rails 14Bi (i=1-2) arranged at predetermined intervals between the upper rail 14U and the lower rail 14L, and an end post 16 connected to an end of the upper rail 14U. The lower end of the end post 16 is connected to an end of a lower end member 12L of the door support member 12, which will be described later. One end of the upper rail 14U and the lower rail 14L each has a female threaded hole into which an end of a fixing bolt 24 is inserted. The end post 16 is arranged facing and approximately parallel to the fixing support 18.

[0016] The door 10 includes an upper rail 10U, a lower rail 10L, a plurality of small rails 10Bi (i=1-8) arranged at a predetermined interval between the upper rail 10U and the lower rail 10L, and an end post 10A connecting one end of the upper rail 10U to one end of the lower rail 10L. The door 10 is supported rotatably between an upper end member 12U and a lower end member 12L of the door support member 12 via hinge members 22 that penetrate the other end of the upper rail 10U and the vicinity of the other end of the lower rail 10L, respectively. The outer vertical dimension of the door 10 may be set appropriately to any of dimensions of, for example, 150 cm, 170 cm, or 190 cm depending on the situation of the opposing wall surfaces STA and STB that form the entrance / exit PA of the room. The door support member 12 is composed of an upper end member 12U, a lower end member 12L, and a connecting member 12C that connects one end of the upper end member 12U to one end of the lower end member 12L. The connecting member 12C is disposed facing and approximately parallel to the fixing post 20. As shown in Fig. 6, the side portion of the connecting member 12C has female screw holes 12CHa and 12CHb at the upper and lower ends, respectively, into which the ends of the fixing bolts 24 are inserted.

[0017] As shown enlarged in Fig. 5, the fixing bolt 24 is composed of a disk-shaped head 24T formed at the end of the male thread and a tightening nut member 24N fitted to the male thread. The head 24T is fitted into a central recess 26R of a disk-shaped pad 26 shown in Fig. 3(b). On the lower surface of the pad 26 that abuts against the wall surfaces STA and STB, as shown in Fig. 3(a), a plurality of grooves 26g are formed that are larger than the area of ​​the head 24T and are partitioned by a plurality of concentric thin walls 26a. The head 24T of the fixing bolt 24 is also fitted into a central recess 25R of an oval pad 25 shown in Fig. 4(b). 4(a), a plurality of elliptical grooves 25g, which are larger than the area of ​​the head 24T and are partitioned by a plurality of concentric elliptical thin walls 25a, are formed on the underside of the pad 25 that contacts the wall surfaces STA and STB. As a result, when the tightening nut member 24N is rotated, the disk-shaped head 24T is pressed against the wall surfaces STA and STB via the pads 25 and 26. As a result, the undersides of the pads 25 and 26, which have a contact area larger than the contact area of ​​the head 24T, provide a contact area that generates a sufficient frictional force with the wall surfaces STA and STB, and the undersides of the pads 25 and 26 can be easily and accurately installed between the wall surfaces STA and STB.

[0018] As shown in Figs. 2(a) and (b), the lock / unlock mechanism 34 includes a pair of strikers 34A and 34B, such as strike locks, a fixed pin 36 that connects one end of the pair of strikers 34A and 34B through a through hole in the end post 10A, and a receiving seat 30 that is provided on the end post 16 and receives and locks the other ends of the pair of strikers 34A and 34B. The vertical position of the lock / unlock mechanism 34 in the door 10 is set to a position above the center position of the end post 10A of the door 10. The pair of strikers 34A and 34B, which are fixed together at the end of the fixed pin 36, are arranged opposite each other across the end post 10A. The pair of strikers 34A and 34B each have an elongated hole 34S at the base end through which the fixed pin 36 passes. The elongated hole 34S extends a predetermined length in the longitudinal direction of the strikers 34A and 34B. A knob 34a is provided at the end of each of the pair of striking members 34A and 34B. 1, when the door 10 is closed, the portions of the pair of latch members 34A and 34B where the knobs 34a are provided are respectively latched by the catches 30a of the receiving seats 30. This prevents pets from escaping from each room to other places such as the corridor or entrance. When the door 10 is opened, the portions of the pair of striking members 34A and 34B where the knobs 34a are provided are both rotated counterclockwise together as shown in FIG. 2(b) and pulled away from the catches 30a of each receiving seat 30, allowing the door 10 to rotate between the upper end member 12U and the lower end member 12L of the door support member 12 via each hinge member 22. Therefore, a person can move from the room to another place such as a corridor or a hallway through the room entrance / exit PA. After the person passes through the room entrance / exit PA, the portions of the pair of striking members 34A and 34B provided with the knobs 34a are again locked by the catches 30a of the receiving seats 30 from outside or inside the room.
