Description

[Technical Field]

[0001] The present invention relates to a detachable pet door that can be installed on an existing hinged door. [Background technology]

[0002] Traditionally, indoor doors are often left open enough for pets such as dogs and cats to pass through, allowing them to move freely between rooms. However, doing so during times when room temperature is controlled using air conditioners, such as midsummer or midwinter, poses the problem of reduced heating and cooling efficiency due to the open door. For this reason, some homes have installed doors on the doors themselves to allow pets to enter and exit, but in the case of rental housing, it is difficult to modify the doors themselves because the property must be restored to its original condition when the occupant moves out.

[0003] If the door is a sliding door, installing a panel with a pet entrance in the opening of the sliding door when the door is half-open allows pets to enter and exit without modifying the door. On the other hand, if the door is a swing door, it is possible to install such a panel in the opening of the swing door when it is half-open, but some ingenuity is required to install the panel detachably and to enable the swing door to be opened and closed freely.

[0004] For example, Patent Document 1 discloses a pet door panel that closes the half-open opening of a swing door with a panel while allowing pets to enter and exit through a pet entrance provided in the panel. This pet door panel is rotatably supported on a support post, and this support post is composed of an extension rod supported on the floor and ceiling. Furthermore, Patent Document 2 discloses a configuration in which the above-mentioned pet door panel is fixed to the swing door itself. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-115461 [Patent Document 2] U.S. Patent No. 10,435,942 Summary of the Invention [Problem to be solved by the invention]

[0006] The technology disclosed in Patent Document 1 leaves the top of the hinged door open when it is half-open, which does not completely solve the problem of poor heating and cooling efficiency. Also, as disclosed in Patent Document 2, it is possible to provide a flap that closes the top of the hinged door when it is half-open on the pet door panel disclosed in Patent Document 1, but with this configuration, it is difficult to fix the position of the flap when the hinged door is open. Therefore, the flap falls every time the hinged door is opened, which requires the trouble of resetting the flap above the half-open door.

[0007] The present invention has been made in consideration of the problems of the conventional technology, and aims to provide a detachable pet door that can be detachably installed on an existing hinged door, can avoid a decrease in heating and cooling efficiency, and can also allow the hinged door to be freely opened and closed in the same way as when the pet door is not installed. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the present invention employs the following technical means. First, the present invention is based on the premise of a detachable pet door that is attached to an existing hinged door. The pet door according to the present invention comprises a frame body, a pet entrance and an expandable member. The frame body is made up of an upper frame material and The door is equipped with two vertical frame members. The frame body is positioned adjacent to the frame of the swing door on the side that the swing door moves to when it is open. The pet entrance is provided at the bottom of one of the vertical frame members. The elastic member is positioned between the upper frame member and the ceiling above the upper frame member, and presses the frame body against the floor by expanding.

[0009] The detachable pet door of the present invention is constructed by pressing a frame with a pet entrance and exit against the floor with an expandable member, so it can be detachably installed on an existing swing door without requiring any special processing. Furthermore, the swing door itself can be opened and closed just like in a normal state, and even when in use, the upper part of the swing door is closed when it is half-open, so there is no loss of heating and cooling efficiency.

[0010] In the above configuration, the hinged door can have a latch, and the vertical frame member with the pet entrance can have a latch receiver that fits with the latch of the hinged door in the half-open state. Located on the opposite side of the frame It is also possible to adopt a configuration in which part or all of the end portion is movable toward the other vertical frame member opposite the vertical frame member. [Effects of the Invention]

[0011] According to the present invention, a detachable pet door can be provided which can be detachably installed on an existing hinged door, can avoid a decrease in heating and cooling efficiency, and can also allow the hinged door to be freely opened and closed in the same way as when the pet door is not installed.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. Although not particularly limited, in this embodiment, the present invention is embodied in an example where it is applied to a hinged door that moves toward the room when opened. Fig. 1 is a perspective view that schematically shows the appearance of a detachable pet door in this embodiment.

[0014] As shown in Fig. 1, the detachable pet door 1 of this embodiment includes a frame body 10 and an expandable member 20. As shown in Figs. 2 to 4, the frame body 10 is disposed adjacent to the frame 3 of the hinged door 2 on the side (here, the room side) to which the hinged door 2 moves when opened. The right end of the hinged door 2 as viewed from the room side is connected to the frame 3 via a hinge 4. Hereinafter, the short side direction of the hinged door 2 may be referred to as the width direction, the long side direction of the hinged door 2 as the up-down direction, and the thickness direction of the hinged door 2 when closed as the depth direction.

[0015] The frame body 10 is composed of an upper frame member 11, two vertical frame members 12 and 13, and a lower frame member 14. In this embodiment, the upper frame member 11, the vertical frame members 12 and 13, and the lower frame member 14 are composed of long rectangular plate materials. Although not particularly limited, the upper frame member 11 and the vertical frame members 12 and 13 have the same rectangular cross section. That is, the length of the short side of the upper frame member 11 is the same as the length of the short side of the vertical frame members 12 and 13, and the thickness of the upper frame member 11 is the same as the thickness of the vertical frame members 12 and 13. Furthermore, the length of the short side and long side of the lower frame member 14 are the same as those of the upper frame member 11, but the thickness of the lower frame member 14 is thinner than that of the upper frame member 11. The thickness of the lower frame member 14 may be any thickness that does not hinder the opening and closing of the hinged door 2, but it is particularly preferable that the thickness be slightly smaller than the distance between the bottom surface of the hinged door 2 and the floor 40.

[0016] The frame body 10 has an overall rectangular cross section, with the upper ends of two vertical frame members 12, 13 connected by an upper frame member 11 and the lower ends of the vertical frame members 12, 13 connected by a lower frame member 14. While the method for connecting the frame members is not particularly limited, a detachable assembly-type connecting method such as screwing or fitting is particularly preferred. The inner periphery of the frame body 10 is configured to match the inner periphery of the frame 3 of the hinged door 2 to be installed, i.e., to match the outer periphery of the hinged door 2 to be installed. In this embodiment, one blade of the hinge 4 is fixed to the inner periphery of the frame 3, and the other blade is fixed to the side of the hinged door 2 on the side of the hinged door 2 on the side opposite the door tip. Therefore, by matching the inner periphery of the frame body 10 to the inner periphery of the frame 3, the frame body 10 does not interfere with the opening and closing of the hinged door 2. In this embodiment, the widthwise length of the inner periphery of the frame body 10 (the widthwise length of the upper frame member 11) is slightly larger than the widthwise length of the inner periphery of the frame 3. This reliably prevents the vertical frame member 13 from interfering with the hinge 4. The hinged door 2 is provided with a lever-shaped handle 5 that can be grasped by the user. The user can push or pull the hinged door 2 by grasping the handle 5 and rotating it downward along the hinged door 2. The shape of the handle 5 is not particularly limited, and any known shape such as a doorknob shape can be adopted.

[0017] Furthermore, although not particularly limited, it is preferable that an elastic material such as rubber is disposed on the lower surface of the lower frame material 14 that comes into contact with the floor 40. This can prevent problems such as damage to the floor 40.

[0018] The telescopic members 20 are arranged between the upper frame member 11 and the ceiling 50 above the upper frame member 11 (see FIG. 4). The telescopic members 20 are rod-shaped members that extend to press and fix the frame body 10 against the floor 40. Although not particularly limited, in this embodiment, two telescopic members 20 are arranged between the upper frame member 11 and the ceiling 50 along the width direction of the upper frame member 11.

[0019] A known structure can be adopted for the telescopic structure of the telescopic member 20. For example, a configuration can be adopted in which male threads are provided on the outer periphery of both ends of the main body 21 of the telescopic member 20, and telescopic sections 22, 23 are provided with female threads on the inner periphery that screw into the male threads. In this configuration, the amount of protrusion of the telescopic sections 22, 23 from the main body 21 can be adjusted by rotating the telescopic sections 22, 23. This allows the length of the telescopic member 20 to be freely adjusted. Although not particularly limited, it is preferable that an elastic material such as rubber is arranged on the contact surfaces of the telescopic sections 22, 23 with the upper frame member 11 or the ceiling 50. This makes it possible to avoid problems such as damage to the ceiling 50. Note that the telescopic section does not need to be provided on both ends of the main body of the telescopic member 20, and may be provided on only one end.

[0020] A pet entrance 30 is provided at the bottom of the vertical frame member 12 arranged on the door tip side of the hinged door 2. A known structure can be adopted for the pet entrance 30. For example, in this embodiment, as shown in Figs. 1 to 3 and 6, the pet entrance 30 is configured to include a swinging door 31. The swinging door 31 is pivotally supported at the top of an opening 32 provided in the vertical frame member 12 around a rotation shaft 33 arranged along the horizontal direction (the short side direction of the vertical frame member 12) in a state in which it can rotate. In addition, an iron piece 34 is fixed to the bottom end of the swinging door 31, and a magnet piece 35 is fixed to the surface of the bottom end of the opening 32.

[0021] When a pet is not passing through, the swinging door 31 stops at a position where the iron piece 34 and the magnet piece 35 are attracted to each other due to the weight of the swinging door 31 and the action of the iron piece 34 and the magnet piece 35. This closes the pet entrance 30. When the pet presses the swinging door 31 with its head, the swinging door 31 swings in the direction of the pet's entry and exit, allowing the pet to enter and exit through the pet entrance 30.

[0022] When allowing a pet to enter and exit through the detachable pet door 1 having the above-described configuration, as shown in FIG. 5, the hinged door 2 is fixed in a half-open state with the leading edge of the hinged door 2 facing the inner circumferential surface of the shorter end of the vertical frame member 12 on the room side, as shown in FIG. 5. The fixing method is not particularly limited. Any known method can be used, such as a method of connecting and fixing the hinged door 2 to the vertical frame member 12 using string, rubber, etc., or a method of fixing the hinged door 2 to the vertical frame member 12 by magnetic force using an iron piece and a magnet piece provided at a position where the vertical frame member 12 and the hinged door 2 face each other. In this embodiment, as a particularly preferred embodiment, the hinged door 2 is fixed in a half-open state by a latch 6 (see FIG. 4) provided on the hinged door 2 and a latch receiver 7 provided on the vertical frame member 12. That is, the latch 6 is provided at the vertical center of the leading edge of the hinged door 2 and moves in and out along the width direction of the hinged door 2 in conjunction with the rotation of the handle 5. The latch receiver 7 is provided at a position facing the latch 6 of the hinged door 2 in a half-open state at the end of the vertical frame member 12 on the room side in the short direction. The latch 6 and the latch receiver 7 are fitted together to maintain the hinged door 2 in the half-open state. The structures of the latch 6 and the latch receiver 7 are well known, so a description thereof will be omitted here.

[0023] As explained above, the detachable pet door 1 has a configuration in which the frame 10 equipped with the pet entrance 30 is fixed between the floor 40 and the ceiling 50 using the expandable member 20, so it can be detachably installed on an existing hinged door. Furthermore, even when the hinged door 2 is half-open so that a pet can enter and exit through the pet entrance 30, the upper part of the hinged door 2 is blocked by the upper frame member 11, so a decrease in heating and cooling efficiency can be avoided. Furthermore, because the frame 10 does not interfere with the opening and closing of the hinged door 2, the hinged door 2 can be opened and closed freely in the same way as when the detachable pet door 1 is not installed.

[0024] In the above-described embodiment, the vertical frame member 12 is arranged with its short side aligned with the depth direction. In this arrangement, for example, if the length of the short side of the vertical frame member 12 is relatively long or if the protrusion of the latch 6 provided on the hinged door 2 is small, the latch 6 may not engage with the latch receiver 7. To avoid this situation, as shown in FIG. 7, the vertical frame member 11 may be configured so that its end on the room side is closer to the hanging point than its end on the frame 3 side, as long as it does not interfere with the opening and closing of the hinged door 2. Note that FIG. 7 is a plan view of the frame body 10 viewed from above. For ease of explanation, the vertical frame members 12 and 13 are indicated by dashed lines in FIG. 7.

[0025] It is also possible to adopt a configuration in which the position of the room-side end of the vertical frame member 12 can be changed. Such a configuration can be realized, for example, as shown in Figures 8 and 9, by supporting the frame 3-side end of the vertical frame member 12 rotatably with respect to the upper frame member 11 and the lower frame member 14, so that the vertical frame member 12 can be fixed in a desired position. Note that Figure 8 is a plan view of the frame body 10 seen from above, and Figure 9 is a cross-sectional view of the lower frame member 14 seen from above. For the sake of explanation, the vertical frame members 12 and 13 are shown by dashed lines in Figure 8.

[0026] As shown in FIG. 8, the upper frame member 11 and the vertical frame member 12 are secured together with fixing screws 71 and 72. The two fixing screws 71 and 72 are inserted from above the upper frame member 11 through a through-hole 73 at the frame-3-facing end of the upper frame member 11 and an arc-shaped through-groove 74 at the room-facing end of the upper frame member 11, centered on the through-hole 73. The screws then thread into corresponding screw holes at the top of the vertical frame member 12. As shown in FIG. 9, the lower frame member 14 and the vertical frame member 12 are secured together with a lower end of the vertical frame member 12 that abuts against the top surface of the lower frame member 14. The vertical frame member 12 has cylindrical protrusions 75 and 76 at its lower end. The protrusion 75 is inserted into a through-hole 77 at the frame-3-facing end of the lower frame member 14. Furthermore, the protrusion 76 is provided on the room-side end of the lower frame member 14 and is inserted into an arc-shaped through groove 78 centered on the through hole 77. In this configuration, a stopper 79 is used to secure the vertical frame member 12 in the desired position. The stopper 79 is made of an elastic material and has a shape that allows the entire stopper 79 to be pressed into the through groove 78. By arranging the stoppers 79 on both sides of the movement direction of the vertical frame member 12, the vertical frame member 12 can be secured in the desired position. By adopting this configuration, the room-side end of the vertical frame member 12 can be positioned closer to the hanging point than the end on the frame 3 side. Note that in Figure 8, only the shafts of the screws 71 and 72 are shown for the sake of explanation.

[0027] Furthermore, instead of making the room-side end of the vertical frame member 12 movable, a configuration may be adopted in which the portion of the vertical frame member 12 including the latch receiver 7 is capable of advancing toward the latch 6 of the hinged door 2. For example, the vertical frame member 12 may be configured so that a rectangular parallelepiped first portion including the latch receiver 7 and the remaining second portion are separable. In this case, for example, the first portion is configured as a rectangular parallelepiped block, and the second portion is configured with a recess that fits into the first portion. In this configuration, the first portion can be protruded toward the hinged door 2 by placing a spacer with a predetermined thickness between the first portion and the recess of the second portion.

[0028] In this way, by configuring part or all of the end of the vertical frame member 12 on the opening side of the hinged door 2 to be movable toward the other vertical frame member opposite the vertical frame member, it is possible to reliably prevent the latch 6 and the latch receiver 7 from becoming misfit.

[0029] As described above, according to the present invention, a pet door can be realized that can be detachably installed on an existing hinged door, that can prevent a decrease in heating and cooling efficiency, and that can allow the hinged door to be opened and closed freely in the same way as when the pet door is not installed.

[0030] The above-described embodiments do not limit the technical scope of the present invention, and various modifications and applications are possible within the scope of the present invention, even if not already described. For example, in the above-described embodiments, the upper frame member 11, the vertical frame members 12 and 13, and the lower frame member 14 are each composed of a single member. However, the upper frame member 11, the vertical frame members 12 and 13, and the lower frame member 14 may each be composed of multiple members. In addition, in the above-described embodiments, the frame body 10 is described as including the lower frame member 14, but the inclusion of the lower frame member 14 is not essential. As shown in FIG. 10 , it is also possible to adopt a frame body 80 having a U-shaped cross section with an open lower end, in which the upper ends of the two vertical frame members 12 and 13 are connected by the upper frame member 11. In this case, it is preferable to place an elastic material, such as rubber, on the contact surfaces of the vertical frame members 12 and 13 with the floor 40 to avoid problems such as damage to the floor 40. Furthermore, in the above-described embodiments, the frame body 1 In the above embodiment, the vertical frame member 12 and the vertical frame member 13 are configured to be aligned with the frame 3, but the frame body 10 may be larger than the frame 3. For example, in FIG. 1, the vertical frame member 13 may be configured to be positioned to the right of the end of the frame 3 on the hanging side. Also, although the hinged door 2 is configured to be equipped with a latch 6, it is not essential that the latch 6 be equipped. Furthermore, in the above embodiment, the lengths of the vertical frame member 12 and the vertical frame member 13 in the short side direction are the same, but the width of the vertical frame member 13 on the hanging side in the short side direction may be smaller than the width of the vertical frame member 12 in the short side direction. [Industrial Applicability]
