Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to flexible, compact and lightweight lids, bulkheads and panels.

[Description of the Prior Art] The pet door of the present invention is disclosed in U.S. Patent No. 3.797.554.
This is an improvement on the pet door structure described in No.

The US patent supports a flexible door 38 with several spaced projections 40. These projections are held in place by an elongated opening formed by a stalk-shaped cross-section at 34. As animals repeatedly pass through the door, the securing area shown in FIG. 4 may wear and tear, requiring replacement of the door 38 and/or the trim element 44.

This door structure requires the ends of the door and trim elements to be removed by sliding them through the elongated opening 36 before a replacement door and trim element can be slid through the elongated opening 36 and installed.

OBJECTS OF THE INVENTION The object of the invention is to provide such fixing modes and replacement means by fixing the flexible trim and the upper part of the flexible door in place by means of plugs and holes, and by fixing the surfaces of these upper parts. The purpose of the present invention is to abut the edges of the frame and improve assembly by having those surfaces abut above the opening to provide a snug seal.

SUMMARY OF THE INVENTION The present invention relates to a two-way pet door and frame that can be assembled over a cut-out opening in a door or wall of a room. The invention consists of four components in total and includes the following elements in the assembled state:

16. A rigid first rectangular frame having a rectangular cut-out opening therein.

2. A rigid second rectangular frame having a larger rectangular opening therein.

3. A flexible door attached to the first rectangular frame by plug and hole attachment.

4. A flexible rim attached to the first rectangular frame by a stopper and a hole for sealing between the rectangular opening of the flexible door and the rigid frame.

the first and second rectangular frames may be made from plastic;
It can also be formed by a plastic molding process.

The flexible door and flexible trim may also be made from a rubbery flexible compound that may be molded by means of a plastic injection molding process. The pet door may be installed in several types of exterior doors or in the wall of the residence. The purpose of a pet door is to allow the pet to freely enter and leave the house without the owner having to open the door.

The pet door is assembled by using a second frame with a large rectangular opening as a template. A second frame is positioned at the appropriate height for the animal and a rectangular opening is traced. The four corners are then drilled large enough to accommodate the spool and provide a cut-out opening in the door. The first frame has a projecting lip for extending it into the rectangular opening to fit into the cutout portion of the door. Appropriate marks for bolt and acorn nut holes may be marked with a bik or some other type of marking tool.

Next, a hole will be drilled through the door of the room. The other three components of the pet door, namely the first rectangular frame, the flexible door, and the flexible trim, are positioned on the outside of the room door and the bolts are attached to the door and the two. It is threaded through the hole in the frame and the acorn nut is tightened. Each of the inner and outer frames of the room door abuts each surface of the room door in an aligned manner. When the first frame is pressed against the outside of the room door, the flexible door and the flexible trim are pressed against the room door by the frame to tightly seal the cutout opening. do. Pet doors are usually installed by attaching the frame with the large rectangular opening to the inside of the room door. This is because the outer frame prevents the flexible rim from swinging open and provides a greater seal against wind gusts and other elements outside the layer. Rigidized sliding doors may also be installed to enhance the seal against the outdoor elements. The lateral parts of the two frames are provided with guides over which the sliding door can be slid downwardly to cover and seal the cut-out opening. Two stop means are also provided in the horizontal region above the two frames. The sliding door is prevented from sliding upwards unless one of said stop means is depressed to remove the edge of the sliding door from the frame. Of course, if the sliding door is properly positioned, pets will not be able to pass through it. This is a safety measure when the pet owner is away on vacation or when the weather is inclement and you want to keep the pet door closed.

The upper horizontal edge of the U-shaped flexible rim above the flexible door is securely attached by a plug and hole combination. Repeated passage of the pet through the pet door eventually weakens the flexible door and the securing area of the trim.

Eventually, the bending will cause so much stress on the upper part that the door will tear and need to be replaced. Replacement of flexible doors and trim is relatively easy. Loosen the series of bolts and acorn nuts, pull the first outer frame off the bolts, remove the old flexible door and trim, and attach the replacement flexible door and trim to the stopper and hole combination in the frame. Reposition it on the body, then pass the first frame back through the protruding bolt and tighten the acorn nut.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 illustrates a section of a pet door installed over a pre-cut opening in an exterior door or wall. The entire periphery of the pet door consists of a first frame and a rectangular second frame 2.
form. The first frame, although only partially shown in Figure 1, is similar to the second frame 2 and is positioned directly behind the second frame and directly behind the pet door. However, in the other figures the first frame is illustrated with reference numeral 10. The rigid rectangular second frame 2 illustrated in FIG. 1 includes a rectangular opening 4 that is slightly smaller than the cut-out opening of the pet door. This rectangular opening 4 is sufficiently wide to allow a flexible door 6 to bend inwardly or outwardly through said rectangular opening.

Also illustrated in FIG. 1 is a generally U-shaped flexible trim 8 for covering the gap between the flexible door 6 and the rectangular opening 4. Whenever the pet enters the house from outside, the U-shaped flexible decorative edge 8 is given room to swing or bend inward.

The first frame 10 has an upper horizontal member constituting a first attachment means and has a substantially rectangular opening through which an animal or pet can pass. This is indicated by reference numeral 12 as a rectangular aperture. The upper end 13 of the rectangular opening 12 is shown in FIG. The rectangular opening 12 is smaller than the rectangular opening 4 of the second frame 2 and is wide enough for the flexible door 6 to pass through it. However,
The flexible rim 8 is wider and cannot pass through the smaller rectangular opening 12. The sectional view of FIG. 3 shows the lower edge of the rectangular opening 12, ie the relationship between the protruding lip 5 and the lower edge of the rectangular opening 12.

A projecting lip 5 extends from the entire circumference of the rectangular opening 4 in the second frame 2. As shown, the step between the lower edges of the two rectangular openings is approximately 1 inch.
It is. The cross-sectional view in FIG. 2 shows the upper edge (protruding lip 5) of the rectangular opening 4 and the upper edge of the rectangular opening 12, and shows that one edge of the two openings faces each other. It will be done. 5 and 6 show the projecting lip 5 of the larger rectangular opening 4. FIG. The flexible door 6 and the flexible trim 8 are transparent so that the outline of the smaller rectangular opening 12 is shown in FIG. Smaller rectangular opening 1
2 contours are shown with reference numbers 14, 16 and 18. As mentioned earlier, the horizontal upper edges of the two apertures are identical. In Figure 1, the smaller rectangular opening 14
The right-hand longitudinal edge is designated by the reference numeral 14, the bottom horizontal edge by the reference numeral 16, and the left-hand longitudinal edge by the reference numeral 18. The right-hand longitudinal edge of the flexible door 6 is designated with reference numeral 20, the bottom horizontal edge with reference numeral 22 and the left-hand longitudinal edge with reference numeral 24. As shown in FIG. 1, the circumference of the flexible door 6 is slightly smaller than that of the smaller rectangular opening 12, so that the flexible door 6 can be opened either internally or externally through the pet door. It can also turn to the side. The right-hand longitudinal edge of the flexible rim 8 is designated by the reference numeral 26, the bottom horizontal edge by the reference numeral 28 and the left-hand longitudinal edge by the reference numeral 30. As shown in FIG.
2 and thus act as a seal or gasket. The three lateral parts of the flexible rim 8 are slightly smaller than the circumference of the larger rectangular opening 4.

The upper end 13 of the smaller rectangular opening 12 and the flexible decorative edge 8
The relationship between the upper horizontal part of the flexible door 6 and the flexible door 6 will be described below. The flexible door 6 comprises a horizontal member 15 above the first frame 10 and an upper horizontal edge extending adjacent to the portion 36 of the flexible door 6 . part 36
The second attachment forms part of the means. Flexible decorative edge 8
Upper edge portions 32 and 34 also extend upwardly and are adjacent to the horizontal member 15 and the upper edge of the flexible door 6. As can be seen, four plugs 38, 39, 40 and 41 are provided, and four complementary circular holes in the section 36 of the flexible door 6 and the sections 32 and 34 of the flexible rim 8 are provided. Reference number 38゛.

39'40'' and 41'. Circular holes and 4
The two plugs fit together and extend the upper portion to the upper horizontal member 1.
5 and form a plug and six assembly for fixing to the upper edge of the flexible door 6. The cross-sectional view of FIG. 5 clearly illustrates this relationship. As will be appreciated, the first frame 10 and the surfaces of the flexible door and flexible trim all interface in alignment with the first frame 1o. This alignment contact feature is for positioning the upper horizontal member 15 on the wall above the flexible door 6 or cut-out opening.

In FIG. 4, the upper mounting surface of the first frame 10 is shown.

5 and 6 also show the upper mounting surface of the first frame 10. The above mounting is such that the surface is substantially flat and is placed against a cut-out opening in the door or wall of the room. Although the surfaces of the flexible door 6 and the flexible trim 8 are spaced apart from the first frame 10, the same attachments as the first frame 10 are attached to the surfaces. This is also shown in FIGS. 5 and 6, where the flexible door 6
, the flexible decorative edge 8 and the first frame 10 are substantially in the same plane and in contact with the door or wall of the room. A plurality of ribs 43 are provided above the first frame 10 to support the stoppers 38, 39 and 40. These ribs provide a flat constraining surface and also provide additional stiffness to the rigid first frame 10. The stopper is made of flexible decorative rim 8 parts 32 and 34.
Alternatively, the length may be the same as the width of the portion 36 of the flexible door 6. The only requirement for the stopper is that it be long enough to support both the flexible door 6 and the flexible rim 8. In the embodiment shown in FIGS. 4 to 7, the plugs are located in each corner and complementary circular holes are located in the portions 32 and 34 of the flexible rim 8 and in the upper portion of the flexible door 6. It is being However, this relationship is maintained by extending the plug away from the first frame 10 and from the surfaces of said sections 32 and 34 and the flexible door section 36, with circular holes in the ribs 43 for receiving the plug. Can be reversed by positioning.

1 and 3, the bottom horizontal edge 28 of the flexible trim 8 and the bottom horizontal edge 22 of the flexible door 6 are shown.
An example is a magnet buried nearby. These magnets are illustrated in the cross-sectional view of FIG. 3 and are identified as follows.

Reference numeral 50 indicates a magnet embedded near 22 at the horizontal edge of the bottom of the flexible door 6.

Reference numeral 52 indicates the bottom horizontal edge 2 of the flexible decorative edge 8
Magnet near 8.

Reference number 54 is a magnet above the flexible decorative edge 8.

A fourth magnet, identified by the reference numeral 56, is then provided, which is fixed to the bottom horizontal edge 16 of the smaller rectangular opening 12. The purpose of these magnets is to resist the door being pushed inward by gusts of wind or weather conditions through the attraction of the two magnets together and to assist in sealing the rectangular opening 4. In FIG. 3, the flexible door 6
It is further illustrated in phantom that the flexible rim 8 swings inwardly, but only the flexible door 6 can swing outwardly. This is because, again, the first frame IO prevents it.

The present invention can be assembled even without the second frame 2. This leaves the cut-out opening in the room door or wall as it is, and attaches the first frame 10 to one side of the room door.
This is achieved by not attaching anything to the other side. 1st
The frame 10, the flexible door 6 and the flexible trim 8 may all be positioned adjacent to the outside of the door or wall of the room and slightly above the cut-out opening. The first ten frames may be secured to the room door by some type of wood screw. Alternatively, the first frame 10, the flexible door 6 and the flexible trim 8 are mounted on the inside of the room door. However,
The preferred method of assembly is to attach the first frame 10, the flexible door 6 and the flexible trim 8 to the outside of the room door. In such a construction, the flexible door 6 and the flexible trim 8 must both curve into the interior of the house, as shown in Figure 3, which provides maximum resistance to the wind. Create.

The second frame 2 is provided for safety and aesthetic reasons, since it covers the cut-out opening from the inside. The rectangular opening 4 is slightly smaller than the cut-out opening and also includes a projecting lip 5 extending into the cut-out opening, as shown in FIG. 5, thereby giving the pet door a so-called finished appearance. It also prevents the pet from getting hurt when going in and out through it.

Several bolt and nut combinations, indicated by reference numeral 60, are used around the two frames. An additional bolt boss 62 is used inside each frame to provide rigidity to the frame.

The elongated holes for joining two frames across the door or wall of any room have various widths. After sizing the door for assembly, the bolt ends can be cut with gold tin and an acorn nut secured thereto to provide a good finished appearance.

The second frame 2 and the first frame 10 are provided with longitudinal guide means 70 on each side of the rectangular opening 4 and the rectangular opening 12.

These guide means 70 have two flanges on each side of the opening. This is provided for a removable sliding door 80 inserted therein. In FIG. 1, a portion of a sliding door 80 made of particle board or plastic, generally rectangular in shape and having a feature 82, is shown in phantom. Sliding door 80 is cut large enough to seal either rectangular opening 4 or rectangular opening 12. In addition, since the second frame 2 or the first frame 10 have identical guiding means, a sliding door can be placed on each side facing the inside or outside of the pet door. Sliding doors further help seal the components whenever the pet door is not used for a period of time, as well as protect them from cold or wet weather. Second frame 2 and first frame 10
Along the upper horizontal portion of the holder are provided stop means shown as two depressable tabs, these stop means being clearly indicated in FIG. 2 by the reference numeral 82. This stop means 82 allows the sliding door 80 to slide into position.
0 cannot slide upwardly past it unless said stop means is depressed.

Although the invention has been described with reference to specific examples, it should be remembered that many modifications may be made thereto.
