Description

  The present invention relates to a pet door that is attached to a screen door.

Conventionally, when pets (dogs, cats, etc.) are allowed to enter and exit indoors and outdoors, pets cannot open and close the doors themselves, so the pets can move freely indoors and outdoors by opening the doors slightly. I was doing. However, when the doors and the like are opened, the efficiency of air-conditioning / cooling is deteriorated, and when the pet passes through the doors and the like, the doors and the like are often fully opened. Further, if the screen door is opened instead of the door, the screen screen is no longer effective. Therefore, the owner has to open and close the screen door each time the pet enters and leaves the room. Thus, some proposals have been proposed so far that an opening is provided in the door or screen to allow the pet to pass therethrough. (For example, refer to Patent Documents 1 and 2.)

The pet door 2 has a screen retainer 3 and a door frame 4. The screen retainer 3 and the door frame 4 hold the screen door net 6, and the lower and side surfaces of the door frame 4 are in contact with the screen door frame 7. Thus, the pet door 2 can be reliably installed at the corner 8 at the lower end of the screen door 1. The door frame 4 is provided with a swing door 5 which will be described later, and a pet can go back and forth between indoors and outdoors via the swing door 5.

  As shown in FIG. 2A, the door frame 4 has a rectangular shape. A door shaft 10 is provided on the upper portion of the door frame 4, and the swing door 5 is attached to the door shaft 10. Can be swung around the shaft. In addition, the door frame 4 is configured to be able to contact and separate at each corner and can be divided into four parts, and the size of the door frame 4 can be changed by replacing each member of the divided door frame 4. It is like that. And the groove part 11 (refer FIG. 3) is formed in the longitudinal direction of each member of the door frame 4, and the net retainer 3 can be stably fixed to the door frame 4 with the screw | thread 23. FIG. A scratch prevention cover 13 is provided at the lower part of the swing door 5 so that the pet does not get scratched at the lower end of the swing door 5 when the pet moves back and forth between the swing doors 5. Moreover, it is comprised so that the screw | thread 23 (refer FIG. 3) can be attached anywhere in this groove part 11. FIG.

  As shown in FIG. 2 (b), the screen retainer 3 has a rectangular shape similar to that of the door frame 4, and is configured to be able to contact and separate at each corner so that it can be divided into four parts. The size of the door frame 4 can be changed by replacing each member of the frame 4. The screen retainer 3 has an I-shaped cross section (see FIG. 3), and is configured so that the screen door net 6 can be easily pressed by the door frame 4 and the screen retainer 3. Further, a screw hole 12 is provided in the net retainer 3, and the screw hole 12 is formed at a position facing the groove 11 of the door frame 4. With such a configuration, the screw hole 12 can be aligned with the groove 11 even if the size of each member of the net retainer 3 changes.

  As shown in FIG. 3, the pet door 2 is configured such that the screen door net 6 is sandwiched between the door frame 4 and the screen retainer 3 so that the outer surface (lower surface) of the door frame 4 is in contact with the inner surface of the screen door frame 7 (FIG. 1). (See) Installed. Further, as shown in FIG. 3 (c), the net retainer 3 has an I-shaped cross section 24 over the entire circumference, and a substantially convex cross section 25 over the entire circumference of the door frame 4 so as to be engaged therewith. The pet door 2 can be attached to the screen door net 6 stably (without slipping). Further, since the screen door net 6 is sandwiched between the I-shaped cross-section portion 24 and the substantially convex cross-section portion 25, the screen door net 6 inside the screen presser 3 is pulled outward, and the screen door net is cut. In doing so, the screen door net 6 is drawn into the screen retainer 3 so that the appearance is improved. Further, in a state in which the net retainer 3 is attached to the door frame 4, the net cut groove 14 is provided on the surface in contact with the door frame 4 along the net retainer 3 over the entire circumference of the door frame 4. By having the mesh cut groove 14, when the screen door net 6 is cut with a cutter knife or the like, only the screen door net 6 above the mesh cut groove 14 is cut without the cutter knife or the like cutting other portions. can do.

  The door shaft 10 is formed in a substantially cylindrical shape, and a door mounting groove 15 for mounting the swing door 5 is formed over the entire length in the longitudinal direction. The swing door 5 is provided at substantially the center in the longitudinal direction of the door shaft 10. The width (indoor / outdoor direction) of the mounting hole 21 for attaching the door shaft 10 to the door frame 4 is formed to be slightly larger than the diameter of the door shaft 10. A spring spring 17 is provided at one end of the door shaft 10, and a spring spring 18 is provided at the other end. Further, in order to stop the swing door 5 in a short time when the swing door 5 swings, the urging directions of the spring springs 17 and 18 as the urging means at both ends with respect to the door shaft 10 are reversed. . With such a configuration, when the swing door 5 swings with the passage of the pet, it is possible to suppress the force of the swing door 5 from opening again, and to bring the swing door 5 into the closed position in a short time. Can be stopped.

  FIG. 4 is a perspective view showing the vicinity of the end portion of the door shaft 10.

  As shown in FIG. 4, the spring spring 17 is attached to the inside of the door frame 4, and the spring spring 17 attached to the end of the door shaft 10 inserts one end of the spring spring 17 into the door attachment groove 15. The door spring 10 is wound a plurality of times from the inside to the outside, and the other end of the spring spring 17 is attached so as to hang down the door frame 4. At this time, since the spring spring 17 is biased, it is configured such that the end of the spring spring 17 is brought into contact with the inner wall of the door frame 4. A spring spring 18 (not shown) at the other end of the door shaft 10 is attached so that the urging force is opposite to that of the spring spring 17.

  An attachment hole 21 for attaching the door shaft 10 to the door frame 4 is provided in a substantially rectangular shape between the spring spring 17 and the swing door 5. A flat mounting hole surface 20 is formed at the lower end of the mounting hole 21. And the door shaft flat surface 19 is formed in the place which contacts the door frame 4 of the door shaft 10. FIG. Thereby, the swing door 5 in the closed position can come into contact with the flat surfaces of the mounting hole flat surface 20 and the door shaft flat surface 19. Therefore, since the frictional force due to the rotation increases when the door shaft 10 rotates, the swing door 5 does not open with a slight external force (wind or the like). On the other hand, when the pet passes, the swing door 5 is brought into a closed state in a short time due to the contact relationship between the mounting hole flat surface 20 and the door shaft flat surface 19 and the elastic force (biasing force) of the spring springs 17 and 18. Can be made.

  FIG. 5 is a view showing the operation of the swing door 5 when passing the pet, (a) is a view when the pet passes from the right to the left of the page, and (b) is a view of the closed state of the swing door 5. (C) is a figure when a pet passes from the left to the right of the page.

  As shown in FIG. 5A, when the pet passes from the right to the left of the page, the elastic force (biasing force) A by the spring spring 18 is larger than the frictional force C received from the mounting hole flat surface 20 (A> C Therefore, the swing door 5 tries to return from the left to the right in FIG. 5B, which is the closed position of the swing door 5. At this time, the swing door 5 tries to return to the closed position by the elastic force A and its own weight, but since there is no stopper for stopping the swing door 5, it passes through FIG. 5B which is the closed position. Similarly, as shown in FIG. 5C, when the pet passes from the left to the right of the page, the elastic force (biasing force) B by the spring spring 17 is larger than the frictional force C received from the mounting hole flat surface 20 ( Since B> C), the swing door 5 tries to return from the right to the left in FIG. 5B, which is the closed position of the swing door 5. At this time, the swing door 5 tries to return to the closed position by the elastic force B and its own weight. However, since there is no stopper for stopping the swing door 5, the swing door 5 passes through the closed position of FIG. That is, the swing door 5 swings around the closed position.

  Thus, only the elastic force A by the spring spring 18 and the elastic force B by the spring spring 17 will finally be in the state of FIG. Here, by providing the mounting hole flat surface 20 and the door shaft flat surface 19, the number of swings of the swing door 5 can be further reduced. That is, when the state close to FIG. 5C is passed from FIG. 5A through FIG. 5B, the end 22a of the door shaft flat surface 19 passes through the mounting hole flat surface 20. Friction force is generated in this direction, and it works in the direction to stop swinging. Similarly, when the state close to FIG. 5A is reached from FIG. 5C through FIG. 5B, the end 22b of the door shaft flat surface 19 passes through the mounting hole flat surface 20. At the same time, a frictional force is generated, which works in a direction to stop the oscillation. As a result, the number of swings is reduced as compared with the case where the mounting hole flat surface 20 and the door shaft flat surface 19 are not provided.

  In addition to the configuration shown in the above embodiment, a plurality of spring springs 17 and 18 may be brought close to one end of the door shaft 10. Further, even if the mounting position of the door shaft 10 is set to an arbitrary position such as a side portion or a lower portion of the door frame 4 and the swinging direction of the swing door 5 is changed, the effect of the present invention is not affected.

  It can be used for pet doors that are installed on screen doors.
