Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to an air conditioner system attachment system. More particularly, the present invention relates to novel devices and systems of attaching a filter to an air conditioner and or heater ducting system. 
       BACKGROUND OF THE INVENTION 
       [0002]    Air conditioner (AC) and Heating systems are deployed in a variety of residential and business complexes. These change the properties of the environment (primarily the temperature and humidity) to more comfortable conditions typically with the aim of distributing the air to an occupied space such as a building or residential space. In addition to the AC and Heating system, users have inserted filter devices into the ducts utilized to spread the air. Typically an open space in the duct has a housing for placement of a filter therein; once inserted therein a door or covering grill is closed thereby enclosing the filter in the housing. It is well known that there are various types of these filtering system employed throughout the world. 
         [0003]      FIG. 1  presents a prior art wall ducting system having a space for insertion of a filter device therein. A wall ducting system  1  is shown having an air filter housing formed from recessed sets of surfaces  2   a - 2   d,    3   a - 3   d  located in the wall that they are formed on. The first set of surfaces  2   a - 2   d  are roughly perpendicular to the wall they are formed on moving inwards towards the wall and away from the surrounding room space. They form a first right surface  2   a,  a first bottom surface  2   b,  a first left surface  2   c  and a first top surface  2   d.    
         [0004]    Similarly, the second set of surfaces  3   a - 3   d  form a peripheral ledge for an airway  4  and for abutting an inserted filter device; also, these are approximately parallel to the wall they are incorporated in and approximately perpendicular to the corresponding first set of surfaces  2   a - 2   d.  Thus, they form a second right surface  3   a  that is integral with the first right surface  2   a  along an edge thereof; a second bottom surface  3   b  that is integral with the first bottom surface  2   b  along an edge thereof; a second left surface  3   c  that is integral with the first left surface  2   c  along an edge thereof; and a second top surface  3   d  that is integral with the first top surface  2   d  along an edge thereof. These  3   a - 3   d  are further integral with each other sequentially along shorter transverse edges forming a ledge back space. A user would typically insert the filter device until it reaches the ledge back space formed by surfaces  3   a - 3   d  and then cover it with a grill, faceplate or similar device. 
         [0005]    The use of these filters has one drawback in that they generally require a grill or cover and during installation they tend to fall out of the ducting or AC or Heater unit. Additionally, there is time wasted in installing the prior art as it takes time to remove the grill or faceplate cover. 
         [0006]    Accordingly, there needs to be some solution to overcome the aforementioned problems.

Legs  10 A and  10 C are parallel to each other and are integrally attached along a respective edge to a centrally disposed intermediate leg  10 B along two respective end edges thereof. This second portion is intended to be slid within along the inside edges of the raised lips  5   a,    5   b  with the filter device already deployed within the confines of  5   a,    5   b.  Thus, a user can vary the size of the attachment device by sliding it inwards and outwards for various size filters and ducting systems. 
         [0095]      FIG. 5A  presents front view of an attachment device having a 3D logo  11  affixed thereto in an embodiment taught herein. This logo is designed in a 3D printer and affixed (using adhesives, silicone seal, glue et cetera) along an upper, lower, inner, outer edge (etc) of the legs  4   a,    4   b,    4   c  for example, alternatively  10   a,    10   b,    10   c  or along a convenient surface of any of the devices herein taught in any embodiment. 
         [0096]      FIG. 5B  presents a 3D image  11  or logo used in the embodiment of  FIG. 5A  in an embodiment taught herein. 
         [0097]      FIG. 6  presents a front view of a double sided tape actuated attachment device for insertion of a filter device therein in an embodiment taught herein. In this embodiment, instead of the materials of arms  4 A,  4 B,  4 C being made from magnetic material or coated with magnetic paint, a double sided adhesive  12  is applied to an outside surface of the attachment device thereby permitting it to be attached to a surface of the recessed portion of  FIG. 1 ; for example, to the side  2 C thereof. Any of the other embodiments for example,  FIG. 2A-2C ,  FIG. 3A-3C, 4A-4B, 5A-5B, 7A -C,  8 A-F can alternatively use this double sided material for attachment in lieu of the magnetic materials previously taught. 
         [0098]      FIG. 7A  presents a front view of a first portion of a collapsible attachment device for easy portage having the ability to hold a filter device in an embodiment taught herein. A U shaped collapsible attachment device first portion has been modified from that shown in  FIG. 2A, 4A  as follows. Two top slots  13   a,    13   c  are located along one of the raised lips  5   a,    5   b  along the top leg  4 A and two bottom slots  13   b,    13   d  are located along one of the raised lips  5   a,    5   b  along the bottom leg  4 C. Of, course to function the slots must be on the top and bottom lips  5   a  or the top and bottom  5   b  lips so that collapsing function can be properly paired between slot and raised protrusion as shown in  FIG. 7B . 
         [0099]      FIG. 7B  presents a front view of a second portion of a collapsible attachment device for easy portage having the ability to hold a filter device in an embodiment taught herein; this second portion is arranged in a U shaped device having three legs  14   a,    14   b  and  14   c.  The first leg  14   a  is parallel to  14   c  and integrated with  14   b  along an edge thereof; similarly leg  14   c  is integrated with an edge of leg  14   b  along an opposite edge of that integrated with leg  14   a.  Thus, a U shaped second portion  14  of a collapsible attachment device is modified from that shown in  FIG. 4B . In this figure,  7 B two sets of inwardly directed raised protrusions  15   a,    15   b  are presented along the outer portions of legs  14   a  (top thereof),  14   c  (bottom thereof) of the U shaped device; it should be understood that these raised protrusions are directed towards those on an opposite leg. In this fashion, those raised protrusions  15   a,    15   b  on leg  14   a  are directed towards those on leg  4   a  and those of  14   c  are directed to those on  4   c.  It is clear from the figure that the raised protrusions are cleats or mushroom head types that are designed to engage by sliding into a slot along the neck of the protrusion and the head thereof thereby holding the device in place within an engagement site. 
         [0100]      FIG. 7C  presents a closeup of an engagement site for the first and second portion of the collapsible attachment device of  FIGS. 7A and 7B  in an embodiment taught herein. The engagement sites of first portion  4 :  13   a,    13   b,    13   c,    13   d  engage corresponding protrusions on the second portion  14 . For example, an engagement site  13   b  is shown such that a raised protrusion is inserted large head down into a slot  13   g  of the engagement site  13   b  that has a curved back  13   e  along the raised lip. The slot narrows dramatically as it travels down the raised lip  5   a,    5   b  to a small overhang or depression slot  13   f  so that the head of the raised protrusion can not disengage therefrom. Even smaller raised protrusions on the surfaces therein are optional to help ‘snap’ the part in place. 
         [0101]      FIG. 8A  presents a front view of two portions of a size adjustable attachment device for insertion of a filter device therein such that it is fully extended in an embodiment taught herein. Two corresponding L shaped foldable size adjustable attachment devices  16  (L shaped device for short) are shown in  FIG. 8A .
