Description

DOOR FOR PETS WITH REMOVABLE DECORATIVE FRAMES TECHNICAL FILE The invention relates to doors for pets and, more specifically, to an adjustable, aesthetically pleasing and adjustable pet door that can be installed in doors of pet owners' homes, of different thicknesses, which allows the owners of pets customize the exterior frames of the doors for pets, at the same time that it is substantially avoided that the cold, the rain, lost pets and unwanted intruders enter the house of the owner of the pet by means of a closing mechanism.

BACKGROUND OF THE ART It is known to install openings or doors for pets in the doors of houses to allow pets to easily get out and enter the house without the intervention of their owners. Pet doors known to date are usually installed in an opening made in the doors or walls of pet owners' homes. In many cases, the components of these pet doors are designed to be nailed or bolted to house doors, which complicates the installation of pet doors. Additionally, the pet doors hitherto known are not suitable for all types of housing doors. In general, they have different thicknesses and other custom properties. In cases where pet doors are properly installed inside the openings formed in the doors of the houses, it is known that the passageway created to allow the exit and entry of pets into the houses creates certain inconveniences. For example, it is known that certain weather conditions, such as rain and cold, penetrate homes through the passageway, even when pet doors are not being used to exit or enter. On the other hand, making the catwalk through the door of a relatively large size for large pets can pose a safety issue for pet owners. In some cases, stray animals are known to enter the homes of pet owners through the pet doors. In other cases, young children and intruders could pass through the passageway and have access to the homes of pet owners. In addition, the doors for mascots hitherto known look very simple and are usually unpleasant from the aesthetic point of view, especially when they are placed on some decorative doors of dwellings or doors of dwellings adjacent to interior or exterior decorative sections of a dwelling. So that these doors for pets so far known can subtract the exterior and interior decoration, not go with it or be placed in another place that is not the facade of the house. For example, typical pet doors have square frames attached to the door of the house with screws, nails or other fasteners. In addition, typical pet doors do not allow homeowners to make style changes to the pet door after installation. Similarly, the pet doors hitherto known can be improved. Adjustable pet doors are required to fit custom-sized, adjustable or customizable housing doors to fit the openings formed in the housing and front doors. Providing adjustable pet doors would greatly increase the convenience and applicability of pet doors. It is desirable that the pet door has an aesthetically pleasing appearance. It is also convenient for the owner to replace or change a decorative feature of the pet door on the other to vary its style, color or architectural form in order to adapt it to the facade of the house. On the other hand, you also need a pet door that offers security features to be able to close and secure it. For example, when the pet is going to remain inside the house or when the pet door is not being used, to prevent intruders, children and other animals from passing through it. The components and installation techniques of pet doors can also be improved. In particular, it should not be necessary to drill holes in the door of the house or introduce fasteners since installing the doors for pets according to these conventional forms complicates the installation. DIVU LGATION OF THE INVENTION A pet door is presented for installation in doors of pet owners' homes in order to overcome the disadvantages of already known pet doors. The pet door includes a subframe assembly that attaches or otherwise attaches to the door of the home and defines a passageway through which pets can leave and return to their owner's home. In some embodiments of the design, decorative frames can be attached to the subframe assembly that is attached to the door of the dwelling. These decorative frames can be attached to the section of the frame inside or outside the house. The interior and exterior decorative frames can have the same decorative appearance or a different one and can be exchanged or replaced to adapt to different designs, decorations, styles and tastes. So that the appearance of the pet door can be customized to suit the tastes of pet owners or to fit the decoration of their homes through different decorative frames without changing the subframe assembly.

A subframe assembly defines an opening in the door of the house and can be adjusted with main frame pieces, which are removed or added as necessary so that the pet door can be used with housing doors of different thickness . Specifically, subframe mainframe parts can be added or removed to adapt the pet door to housing doors of different thickness. A mobile flap covers the open passage formed by the subframe. The lower part and the sides of the mobile flap preferably carry magnets and / or magnetically active ferrous materials which work with the opposing magnets and / or magnetically active ferrous materials located around the subframe assembly so that the lower part and the sides of The mobile fin can be reliably held in place to close the passage and thereby substantially prevent cold, rain and other weather conditions from entering the pet owner's home when the door is not used frequently. A removable safety panel can also be supplied to place it through the open passageway. A locking mechanism, such as a spring latch, slides in and out of the subframe elements to prevent unauthorized removal of the security panel, to prevent lost pets and intruders from having access to the owner's home. .

METHODS OF REA LIZATION OF THE INVENTION Referring to Figure 1, a pet door 100 includes at least one removable decorative outer frame 1 1 0 and one moving fin 120, which may be made primarily of plastic, vinyl rubber and / or or of appropriate flexible materials. The upper part of the fin 120 is installed in a subframe (as illustrated in Figure 3) of the pet door 100 and the pet can move it to allow him to enter and exit the house through a passage 1 22 formed inside of an opening through the door of the housing 1 0. Although the specification speaks of the invention in relation to its installation in a "door" housing, those skilled in the art generally have to interpret that the inventors refer to the housing door 1 0 in a broader sense that includes a wall or other part of the dwelling or residence in which the door can be installed for 100. In the realization of the illustrated design, the upper part of the fin 120 has a curved or arched shape. As noted with reference to Figure 10B, this arched shape can facilitate the opening and closing of the sides and bottom of fin 1. Other shapes can be used for fin 1, 20 example, according to the shape of the frame and decorative sub-frame.

For reference and without limitation, the side 12 of the housing door 10 is designated as the interior side, and the side 14 of the housing door 10 is designated as the exterior side. For explanatory purposes, an "exterior" decorative frame refers to a decorative frame 1 10 placed in or on an element or assembly of the sub-frame adjacent to the facade of the door of the dwelling 10 on the outside of the door of the dwelling 1 0 The decorative frame 1 1 0 can be used inside, outside or both inside and outside of the housing door 10. Referring to Figures 2 to 4, 6A, 6B, and 1 1 AD, the door for pets 1 00 may optionally include a security door or panel 200. When the pet door is not used, the security panel 200 may be placed through the passageway 1 22, whereby the passage 122 closes substantially and is can block, so that intruders, children and animals can not enter the house through the pet door 1 00. The security panel 200 is secured along the passage 1 22 by a locking mechanism 210. In a realization of the design, the mechanism of closure 2 1 0 includes a handle 2 1 2 and pins 2 14 (hereinafter referred to as bolts, slide rails or posts). When used, the locking mechanism 2 1 0 is actuated by turning the handle 2 12, whereby the sliding bolts 214 move in and out of a part of the pet door, such as the holes 2 1 8 ( Figure 4), and in this way lock or unlock security panel 200, as required. Those skilled in the art will note that other 2 1 0 locking mechanisms and others with figurations may be used, such as vertical bolts and / or reinforced holes. Figure 3 illustrates the components of a realization of the pet door design 100 that are assembled to cover the interior and exterior of the door of the housing 10. As illustrated, the pet door 100 includes the frame decorative 1 1 0 and the security door 200 that are inside the house, an exterior decorative frame 1 30 that is outside the residence, the locking mechanism 2 1 0 and the mobile flap 1 20. The pet door 100 includes subframe assemblies 300 and 3 1 0, which are connected to each other with a fastener. The fastener extends between the 300 and 3 1 0 subframe assemblies, through the opening formed in the door of the 1 0 v ew. Thus, unlike the pet doors hitherto known, it is not necessary to drill nor form separate fastening holes in or through the doors of the housing to hold the pet door 100, which causes the additional deterioration of the housing door 10 and otherwise simplifies the installation of the door for pets. The fastener can be inserted through the passage 1 22 in the opening of the door of the housing 10 through the holes 301 (in the sub-frame 300) and towards or through the holes 3 1 1 (in the sub-frame 3 10) , with which both subframe assemblies 300 and 3 1 0 are secured. The fastener is secured so that subframe assemblies 300 and 3 1 0 are joined together against the respective opposite sides of the housing door 1 0 which is placed in the middle. In this way, the sub-frame assembly 300 adheres to the inner side 1 2 of the housing door 10 and the sub-frame assembly 3 10 adheres to the outer side 14 of the housing door 1 0. The complete assembly of the The door of the house without including the decorative frames 1 1 0 and 1 30 is fixed or non-removable until it is disarmed and removed from the door of the dwelling 10. As shown, the sub-frame assembly 300 is a modular assembly and includes elements of frame with individual subframe:. two sub-frame elements 302 and 303, a sub-frame 304 and a lower sub-frame or threshold element 305. The threshold 305 includes a vertical-motion sill 306 which can couple the lower part of the movable fin 120. The flap 1 20 adheres or secures to the upper part of the sub-frame element 304 of the sub-frame assembly 300. In a similar manner, subframe assembly 10 10 is also a modular assembly and includes: two sub-frame elements 3 1 2 and 3 13, an upper subframe element 3 14 and a lower subframe element 3 1 5. A frame assembly is provided 320 to place it around the interior part of the passage 1 22 formed in an opening in the housing door 10 for its framing. The main frame assembly 320 is also a modular assembly and includes: main frame side pieces 322 and 323, a head frame upper piece 324 and a lower frame master piece 325. In one embodiment of the design, the main frame pieces 322 to 325 are removable or separable pieces that are joined side by side to form a center or rectangular tunnel that extends laterally through the opening formed in the door of the housing 10, thereby forming a passageway 1 22 a through which the pet can pass more safely. As shown, each part of the main frame includes one or more elements of the main frame, for example, 322a-c, 323a-c, 324a-c, 325a-c. As would be understood by those skilled in the art, with the present specification, the width of each main frame element and the number of elements of the main frame can be adjusted to suit different thicknesses, widths, heights of doors (or walls) of housing and / or needs of the pet owner. The main frame elements (325 a-c) of any of the cuttable frame pieces are separate and independent of each other. That is, the main frame elements (325 a-c) of a cuttable piece piece are slidingly joined to the respective adjacent main frame elements of a proximal main frame element. In a realization of the design, the main frame parts (322a to 325) are so leveled or aligned with the inner surface of the housing door 10 that although said leveling or alignment configuration is not necessary, it defines the opening, with which is formed the passageway 122. As illustrated in Figures 3 to 5, 7 and 11, the edges of the modular main frame elements 325 (ac) can be configured with "tongue and groove" designs so that an element of main frame 325 (ac) can be adhered to another such element 325 (ac) in a way that allows it to be detached (eg, by unlocking), thereby forming the main frame part 325 and a center or tunnel longer (wider). The number of main frame elements 325 (a-c) that adhere and extend laterally through the door opening can be adjusted to accommodate thinner or thicker doors and / or varying pet heights. In other words, it is possible to use additional main frame elements 325 (a-c) to form a passage 122 through thicker doors and fewer main frame elements 325 (a-c) for thinner doors. In the embodiment of the illustrated design, a main frame 320 includes four main frame pieces 322 to 325, each of which (322 to 325) has three main frame elements (322 (ac), 323 (ac), 324 ( ac), 325 (ac)), adhered side by side with "tongue and groove" connectors. Other methods and means of modular connection of main frame and subframe elements can also be used in conjunction with or as an alternative to the tongue and groove connectors. Alternatively, as shown in Fig. 3A, the main frame elements 322 to 325 can be combined to form a one-piece main frame. In the embodiment of the illustrated design, the main frame parts 325 are arranged according to a square or rectangular design. As would be understood by those skilled in the art, with the present specification, the number of main frame elements 325 (a-c) necessary to cover the inner surface of the opening in the housing door 10 may vary, and that a main frame part 325 with three main frame elements is provided for explanatory purposes, without limiting character. Other pieces of main frame elements 325 (a-c) can be used, for example, 2, 4, 5, 6, 7, etc. Those skilled in the art, with the present specification, will note that the shape of the main frame may also be a matter of style. As shown in Figures 4, 7 and 8, a first main frame member is adhered to a subframe assembly 10 10 in a manner that allows it to be detached (e.g., by a slider or tongue and groove arrangement), and additional main frame elements 325 (ac) can be adhered to the first main frame member 325 to form a main frame assembly 320 with the desired length to accommodate housing doors 10 of different thickness. More specifically, the main frame assembly 320 extends from the subframe assemblies 300 and 3 1 0 to cover the opening formed in the housing door 10. In contrast to the previously known pet door configurations, with the pet door 100 described and illustrated herein, it is not necessary to install or adhere main frame elements 325 (ac) to each other or to another component since each main frame element 325 has a tongue that slides through a groove formed in the subframe assembly 10 so as to allow it to be detached, and in this way, additional main frame elements 325 (ac) adhere in a sliding and detachable manner to the front main frame element 325 (see Figure 7). The other subframe assembly 300 includes a slot for engaging the edges of the assembled main frame member 325. The assembled main frame element 325 can be slid or maintained between the subframe assemblies 300 and 3 10, which are fastened together through the opening formed in the housing door. With all that, no additional mechanical fasteners (for example, nails or screws, etc.) are used to install or secure the main frame elements to each other or to a subframe assembly. This configuration eliminates the need for the user to fix internal or middle door pet components with each other, thereby facilitating and agi lizing the installation with few mechanical fasteners. The other subframe assembly, for example, the subframe assembly 300, is configured to secure the fin 1 20. As shown, the fin 1 20 is installed, secured or adhered to the upper subframe 304 of the subframe 300 assembly. pets can move from side to side the middle and lower sections of fin 1 20 (ie, in and out). The subframe 304 that adheres to the fin 120 also includes the threshold 306. More specifically, a lower subframe member 305 includes a sill or scrim 305 that is composed of or that includes a magnetic element or magnetically active ferrous material. Suitable thresholds that can be used are described in US Patents Nos. 4.65 1 .793 and 4,408,416, the claims of which are incorporated herein by reference. In an exemplary threshold, the lower edge of the fin 120 includes one or more magnets 125. As a result, when the lower edge of the fin 1 20 is adjacent the threshold 305, the threshold magnet 306 is lifted or attracted by the 1 25 at the lower edge of the fin 120, thereby substantially closing the lower part of the passageway 1 22 formed in the opening of the housing door 10. In a similar manner, as shown in the Figures 3, 9, 10A and 1 0B, the edges or sides of the fin 120 may also include magnets or magnetically active ferrous materials 1 27, such as separate magnets, integrated magnetic materials or magnetic chains, which may be attracted to the magnets or magnetic sections 308 of the lateral sub-frames 302 and 303, whereby the sides of the passage 122 are closed. As shown in Figure 9, the side of the vane 120 may include a flexible elbow, rib or "U" shaped part 128. When the magnets 1 27 and 308 they are separated by a sufficient distance, for example, when the flap 120 opens, the piece or 128 takes a non-extended or relaxed position. As the flap 1 20 closes and the magnets 127 and 308 approach each other, the piece 1 28 extends outward and passes from its relaxed position to an extended position due to the attraction between the magnets 127 and 308, whereby a "living" or adjustable hinge is provided which seals the sides of the passageway 122 between the subframe 300 and the door of the window 1 0 and which offers a total closure when the flap 1 20 is in rest position or closing. Additionally, in the embodiment of the illustrated design, as indicated in Figures 3, 8 and 1 0B, the upper edge of the mobile fin 1 20 may have a curved or arched shape. The upper part of the fin 1 20 includes holes through which fasteners are inserted to secure the fin 120 to the subframe assembly 300, specifically, the upper subframe element 304. Referring to Figure 1B, in this embodiment of the specific design, as a pet forces the opening of the moving fin 120 by pushing against the fin 120, the lateral edges of the fin 1 20 taper inward about a central vertical axis so that the fin 120 flexes to acquire a conical shape. When the flap 1 returns to its initial or closing position, the taper or conical shape is undone and the flap 120 returns to its substantially flat initial shape. This tapering action facilitates the separation of the magnetic elements 308 in the sub-frame 300 and the magnetic components 127 on the sides and bottom of the flexible fin 1 20 as the fin 1 20 is opened, while it allows the flap 120 to close and return to its completely flat configuration when in the rest position. If necessary, a security panel 200 may be placed over the passageway 1 22. As shown in Figures, 2, 4, 6A and 6B, a locking mechanism 2 10 may be used to keep the security panel 200 in place. Place it reliably and prevent access to the opening through the interior section of the pet door. In the illustrated embodiment, the locking mechanism 2 1 0 includes posts 2 14 and a handle or arm 2 1 2. The security panel 200 can be locked from inside the house or from outside. For explanatory and illustrative purposes, without limitation, this specification describes a security panel 200 installed from the inside of the house. The posts or pins 2 14 are supported by the guides 2 1 6 on the panel 200 and move in and out of the slots 2 1 8 (also called holes or openings) formed on the sides of the outer decorative frame 1 1 0 , the movable posts 2 1 4 supported by the respective guides 2 1 6 are located on opposite sides of the security panel 200. The sliding movement of the poles 2 14 related to the guides 2 1 6 is controlled by a rotary locking arm 2 1 2 that is manipulated manually by the pet owner when the security panel 200 is removed or returned to the pet door 1 00, or is locked in place. In the embodiment of the depicted design, when the pet owner rotates the locking arm 2 1 2 in a first direction (eg, clockwise), the posts 2 14 of the locking mechanism 2 10 advance. as corresponds to outward and away from each other through the respective guides 2 1 6, through the decorative frame 100, and towards the sub-frame assembly 300. When the posts 2 14 advance towards the holes 21 8, a closure is established of spring type to prevent unauthorized detachment of security panel 200. As is known, these holes 2 1 8 can be reinforced or expanded in the 300 subframe to add more security. In the embodiment of the depicted design, when the owner of the pet rotates the locking arm 2 12 in the opposite direction (e.g., counterclockwise), the poles 2 14 are retracted accordingly, inwardly, one towards the other, through the respective guides 2 16. Accordingly, the posts 214 are removed from the holes 2 1 8, the closing mechanism 210 is unlocked so that the safety panel 200 can be detached and allow the passage of the pet through the passageway 122. After the subframe assemblies 300 and 310 and the main frame 320 are assembled and fixed to the door of the housing 10, exterior decorative frames 1 10 and 130 can be placed in or on the submarco assemblies 300 and 3 10, thereby completing the assembly of an aesthetically pleasing pet door 100 according to one embodiment of the design. More specifically, an exterior decorative frame 1 10 is applied to the sub-frame assembly 300 and an interior decorative frame 130 is applied to the sub-frame assembly 10. The decorative frames 1 10 and 130 may be the same or different and may be interchangeable. For example, a decorative frame can have a specific color or colors, shape and / or size to match the decoration of the outside of the house, while the other decorative frame can be of another color or colors, style, shape and / or size to combine with the decoration of the interior part of the house. The illustrated design of the pet door frames 1 10 and 130 is presented for explanatory and illustrative purposes, without limitation. Thus, at the discretion of previously known pet doors, which generally have simple square frames that are screwed into the door, the design embodiments of the present invention provide aesthetically pleasing pet doors that can be customized and modified. as necessary. The exterior decorative frames 110 and 130, unlike the interior subframe assemblies 300 and 310, and the main frame 320, are easily removable. For example, according to one embodiment of the design, the decorative frames 110 and 130 may include grooves of suitable shape and size to slide over the tops of subframe assemblies 300 and 310. Decorative frames 110 and 130 may also be attached to subframe assemblies with various fasteners, for example, of the "magic lock" type. . " In this way, the decorative frames I 10 and 130 can be removed, while the other components of the pet door, in particular the subframe assemblies 300 and 310, and the main frame 320, remain intact and attached to the door. the housing 10. In the embodiment of the illustrated design, which shows an example of a design of an exterior decorative frame, each decorative frame, 110 and 130, includes a pair of vertical columns 111, 112, 131 and 132, respectively, arranged in parallel and spaced alignment. An integral lid 113 and 133 extends horizontally between the upper portions of the columns and an integral base 114 and 134 extends horizontally between the lower portions of the columns. Vertical columns 111, 112, 131 and 132, the cover 113 and 133, and the base 114 and 134 of the decorative frame section 110 of the pet door surround the passageway 122 through which the pet can enter and exit the dwelling. In the embodiment of the design of Figures 12-14, an example of a flexible fin 1320 is shown. The flexible fin 1320 has a lower edge 1301, side edges 1302 and 1303, and an upper edge 1304. The X-shaped cross section of the side edge 1302 of flexible flap 1320 reveals an anchoring element 1305 and a side edge that includes multiple magnetically attractive elements 1306 attached from the anchor element 1 305 to form a chain, although this anchoring element / plurality of elements 1306 contributes in manufacturing, it would be possible to introduce an inaccurate plurality of magnetically attractive elements during the molding process. The flexible flap opens and returns to its closed position as described in Figure 10B. Those skilled in the art, with the present specification, will note that decorative frames can adhere to a subframe assembly as well as to a housing door. On the other hand, you will notice that decorative frames can cover different parts of a subframe assembly, for example, all or a whole subframe assembly. Additionally, you will notice that a decorative frame can be fixed directly to a housing door.
