PRIORITY CLAIM 
       [0001]    This application claims priority to the earlier filed U.S. Provisional Patent Application 60/991,657, filed on Nov. 30, 2007 which is hereby incorporated herein by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The field of the invention is for a device to hold a door in a fixed location. More specifically, the field of the invention is for an adaptable door stop apparatus for holding a door open when in use. 
       BACKGROUND 
       [0003]    Doorstops are devices that hold a door open, or prevent the door from opening when desired by a user. Since the advent of doors that open and close, there has been a need for a device, object or apparatus that can hold the door open, especially when the door contains some type of hydraulic and/or pneumatic door opener, and/or closer. In most prior art doors, a hydraulic arm is utilized to close the door after entry of an individual into a room, thereby allowing for hands free closing of the door after the individual has utilized the door. The problem with these types of hydraulic arms that close after each use, is that they can be problematic when an individual needs to re-enter a room multiple times. Moreover, they may be much more difficult to open because of the added pressure that it requires to open the door in the first place. 
         [0004]    Today, many different devices have been utilized to hold a door open when desired by an individual. The most simple application is the use of a heavy solid object that is placed in the pathway of the door thereby precluding the door from closing. The object is to put more pressure on the door than the door exerts on its own, thereby allowing the individual to freely cross through the door without the need to continually open the door. However, one problem with such a device is that they take up considerable room and can be easily moved out of place and thereby not have the desired effect. For example, if a brick is placed in front of the door to keep it open, it is possible that the brick may be improperly dislodged and thereby allow the door to close. Additionally, it is entirely foreseeable that an individual may trip on the brick if it is in the path of a walkway or if the individual does not see the device because they are carrying an article or other items that may block their view of the pathway. In this scenario, the problem is that the object may create a more hazardous situation than it&#39;s worth. 
         [0005]    Another contemplated prior art door stop is the wedge. In this embodiment, a wedge may consist of different materials that may be utilized whereby friction between the floor and the bottom portion of the door is used to keep the door open. However, if the floor is a smooth surface, the wedge may not have needed the traction to provide the necessary function. Therefore, often times, the wedge does not stay in place and the door is allowed to close. 
         [0006]    Another contemplated embodiment is the door stop. The door stop is typically a metal bar that is connected to the door via a hinge. At the bottom of the metal bar is a rubber padding that provides the necessary traction and frictional force to keep the door from closing. However, one problem with this door stop is that if the rubber padding becomes dirty, it loses its ability to maintain traction and thereby the friction will allow the door to close even when it is being utilized properly. Additional problems with this type of door stop is the need for permanent attachment to the door. Most times, the hinge is drilled into the door itself and is connected permanently to the hinge. Additionally, when a user desires to release the door stop and allow the door to close, typically it takes sufficient tactile force in order to remove the door stop from its utilized position and allow the door to close. 
         [0007]    Therefore, a need exists for an improved door stop apparatus that may be utilized to keep a door from closing. Additionally, a need exists for an improved door stop apparatus that may be removably attached to a door and can be easily engaged and disengaged by the user without the need for excessive tactile force. Moreover, a need exists for an improved door stop apparatus having a brake and a brake relate and an attachment means for attaching to any door without the need for permanent placement of the door stop apparatus thereon.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0046]    Referring now to the drawings were like numbers are referenced to describe the invention, a door stop apparatus  1  is illustrated. The door stop apparatus  1  has at least a top portion  3  and a bottom portion  5 . The top portion  3  may be oriented such that the top portion is viewable by a user from their vantage point. In an exemplary embodiment the door stop apparatus  1  may be adapted to fit about the bottom portion of a door (see element  71  in  FIG. 3 ). However it should be understood that the door stop apparatus  1  may be utilized on any portion of the door  71  which it may be adapted thereto. In an exemplary embodiment, the door stop apparatus  1  may have a mounting bracket  11  attached to a brake assembly  13 . The mounting bracket  11  may have a first side  15  and a second side  17  whereby the first side  15  is adapted to be in close association with the brake assembly  13 . Moreover, the first side  15  may be pivotally attached to the brake assembly  13  and may rotate about the brake assembly  13  when desired by the individual user. This concept will be explained in further detail below. 
         [0047]    The second side  17  is attached to the first side IS by an attachment portion  19 . The attachment portion  19  may span the distance between the first side  15  and the second side  17 . In an exemplary embodiment, the space between the first side  15  and the second side  17  may be the slightly larger than the approximate distance of the width of a common door. Thereby the width of the door would fit between the first side  15  and the second side  17  and in a preferred embodiment may be adapted for fitment into the attachment portion  19  of the mounting bracket  11 . The mounting bracket may be rotatably attached to the brake assembly  13  as illustrated in  FIG. 2 . 
         [0048]    The mounting bracket  11  further includes the attachment portion  19  which extends away from the brake assembly  13 . The mounting bracket includes the first side  15  which is in pivotal relation with the brake assembly and which extends vertically down to a attachment portion which extends horizontally away from the brake assembly  13 . The attachment portion  19  has a first end  21  and a second end  23 . The first end  21  is in communication with the first side  15  of the mounting bracket  11 , while the second end  23  is in communication with the second side  17  of the mounting bracket  11 . The second side  17  extends vertically away from the second end  23  of the attachment portion  19 . The net effect of the attachment portion  19  is that is encompasses an indentation effect allowing for insertion of a portion of a door to be inserted into the space provided by the attachment portion  19  relationship to the first  15  and second  17  sides of the mounting bracket  11 . 
         [0049]    In an exemplary embodiment, the attachment portion  19  may have a connection means  27  to connect the attachment portion  19  to the door to which is will be attached. In an exemplary embodiment, the connection means  27  may be an adhesive tape  29 . However, it is contemplated that any of a plurality of connection means  27  may be provided such as hook and fastener, screws, nails, snap fit, and the like may also be provided to attach the attachment portion  19  of the mounting bracket  11  to a door portion. It should also be understood that the attachment portion  19  may be affixed to a door, but may also be removed and affixed to another portion of the door when desired by the individual, and/or may be removed from one door and attached to other subsequent doors when desired. 
         [0050]      FIG. 1  further illustrates the brake assembly  13 . The brake assembly has a generally cylindrical housing  31  which may accommodate the brake  33 , the brake release mechanism  35  and the brake application assembly  37 . The housing may contain hydraulic fluid which allows for setting and application of the brake application assembly  37  and the brake  33 . In an exemplary embodiment, the brake application assembly  37  is located at the top portion  41  of the housing  31  whereby the brake  33  is located on the bottom portion  43  of the housing. The brake release mechanism  35  in an exemplary embodiment may be located on the side  47  of the housing  31  whereby it may be activated by the user more easily. In operation, the user would utilize the brake application assembly  37  by pressing down onto it, which would hydraulically activate the brake  33  to extend away from the housing  31  and frictionally attached to a generally planar surface, such as a floor. The brake  33  may have a rubber padding surface  51  which may aid in frictionally attaching to the generally planar surface, such as a floor. The rubber padding surface  51  may be replaced with other materials that may aid in the frictional attachment and stopping of the door assembly apparatus  1 . For example, the padding surface  51  may be comprised of felt, rubber, wood, metal or any other material that would allow for better frictional forces between the brake  33  and the generally planar surface to which is will be frictionally attached. It should be contemplated that the padding surface  51  may be replaceable by any of the contemplated types of material to accommodate better frictional relationship between the brake and the generally planar surface, such as a floor etc. In another exemplary embodiment, it is contemplated that a magnetic padding may be provided to the bottom of the brake  33  whereby when the brake  33  comes in contact with a metallic surface, the padding surface  51  may be comprised of a magnetic which may be strong enough to hold the entire door assembly  1  and attached door  1  from moving. Moreover, it is contemplated that the brake release mechanism  35  may also have a magnetic portion thereon such that is may add to the magnetic attachment to a surface when desired by the individual user. 
         [0051]    In operation, the user may utilize the brake application assembly  37 , by pushing it in, thereby hydraulically activating the brake  33  to be in frictional relation to a surface. It should be understood that as further anticipated, the brake assembly apparatus  37  may be in contact with a generally flat surface such as a floor, but may also be rotated 180 degrees such that the brake assembly  37  may also be in fluid contact with a ceiling. Thereby the door stop assembly  1  may be utilized on both a top portion of a door and a bottom portion of a door  71 . When the brake application assembly  37  is engaged, the brake  33  along with the padding surface  51  will extend out of the housing until the padding surface  51  frictionally contacts a surface at which point the brake  33  stops from extending further from the housing. Because of the frictional forces, the brake causes the door stop apparatus  1  to stop the door from moving from the position it is in relative to the door stop apparatus  1 . 
         [0052]    When the user desires to move the door after application of the brake  33 , the user simply activates the brake release mechanism  35  which is located on the side portion  47  of the housing  31 . When applied, the brake release mechanism  35  causes the brake  33  to move back into the housing  31  and removes the frictional forces of the padding  51  from the generally planar surface, thereby allowing the door which is attached to the attachment portion  19  of the mounting bracket  11  to move freely. 
         [0053]    As illustrated in  FIGS. 2 and 4 , the brake housing  31  may rotate 180 degrees from the mounting bracket  31 . This would allow the brake housing  31  to face another generally planar surface, such as a ceiling instead of a floor. This may be advantageous such that the brake housing  31  is removed from the footpath of an individual that is utilizing the door stop apparatus  1 . However, it is also contemplated that the brake housing  31  may be rotated and locked into any position therebetween such that the brake  33  and the associated padding surface  51  may be utilized on a side surface such as a wall. In an exemplary embodiment, the brake release mechanism  35  may be provided with a frictional padding element, thereby allow it to also be utilized to frictional stop a door from moving. Moreover, both the brake release mechanism  35  and the brake  33  may have magnetic portions  59  which may allow them to attached to a corresponding metal portion of a wall, floor, ceiling or the like. In an exemplary embodiment, a corresponding metal portion may be temporarily adapted to a portion of a wall to allow for the door stop apparatus to have a magnetic attachment to that metal apparatus when a surface isn&#39;t planar enough to provide frictional stopping power.
