CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Application Ser. No. 62/059,348 (“the &#39;348 application”), filed on Oct. 3, 2014 and entitled “Trimless Door Frame.” The &#39;348 application is hereby incorporated in its entirety by this reference. 
    
    
     FIELD OF THE INVENTION 
     Embodiments of the invention relate to door frames having energy absorbing door stops. 
     BACKGROUND 
     Door openings are generally surrounded about their perimeters or “trimmed” with heavy framing to absorb the forces and vibrations associated with repeatedly opening and closing a door mounted within a door opening. Heavy framing is necessary to withstand the day-to-day usage of a door without producing cracks in the surrounding wall due to stress or fatigue. However, door frames are visible and can prevent construction of doors with a smooth, modern appearance with no visible framing. 
     SUMMARY 
     Aspects of the present disclosure relate to door frames that incorporate an energy absorbing door stop to distribute the forces and vibrations associated with opening and closing a door. The energy absorbing door stop helps to absorb and distribute the forces so that lower levels of force are transferred into the surrounding wall and thus obviates the need for a traditional door frame or trim. Decreased levels of force applied to the surrounding wall reduces the likelihood of cracking the surrounding wall due to stress or fatigue over many opening or closing cycles of the door.

     DETAILED DESCRIPTION 
     The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described. 
     The described embodiments of the invention provide a trimless door frame assembly with an energy absorbing door stop. While the energy absorbing door stops are discussed for use with trimless door frames, they are by no means so limited. Rather, embodiments of the energy absorbing door stop may be used in any door including, but not limited to, fully framed or trimmed doors. 
     With reference to  FIG. 1 , embodiments of the invention relate to a trimless door frame assembly  100 . The illustrated door frame is “trimless” in that it does not include the traditional exposed trim on the wall around the door opening that visibly frames the door positioned within the opening. As described in more detail below, the trimless door frame assembly  100  includes a door stop that absorbs shock and/or vibration from the door  500  opening and closing, which may prevent or reduce the amount of shock transferred to adjacent wall  600  (which may be constructed of drywall or any other suitable building materials). The trimless door frame assembly  100  may thus be installed around the perimeter of the door opening within or adjacent the wall  600  without the need for exposed trim on the wall  600  surrounding the door  500 . 
       FIGS. 2 and 3  are perspective and elevation views of a trimless door frame assembly  100  with a door  500  installed within it. As shown, the trimless door frame assembly  100  may be constructed such that the door  500  may be substantially flush with one side of the trimless door frame assembly  100 , and, consequently, the door  500  may be substantially flush with the wall or drywall when the trimless door frame assembly  100  is installed adjacent to the wall or drywall. In some embodiments, the trimless door frame assembly  100  may be used in conjunction with a door closer. The trimless door frame assembly  100  is compatible with both surface mounted and concealed door closing mechanisms. 
       FIGS. 4-7  are schematic end views of constituent components of a trimless door frame assembly  100  that, with other optional components, may be combined to form a trimless door frame assembly  100 . One embodiment of a trimless door frame assembly  100  includes a door frame  150  (formed of a top frame side  150   a , a hinge frame side  150   b , and a strike plate frame side  150   c ), flush mount plate  200 , floating door stop  250 , and support plate  300 , among other hardware or parts. 
     The door frame  150 , flush mount plate  200 , floating door stop  250 , and support plate  300  may be individual components that are assembled together as described below. In some embodiments, the door frame  150 , flush mount plate  200 , floating door stop  250 , and/or support plate  300  may be combined and/or formed from a single piece of material. Any of the below described parts may be constructed from metals, such as aluminum, steel, or other alloys, polymers, composites, or any other material selected for its ease of manufacturing, cost, durability in use, and resistance to corrosion or other environmental conditions. Furthermore, the parts may be produced by machining, casting, stamping, extrusion, any other applicable forming method, or any combination thereof. 
       FIG. 16  is a perspective view of an exemplary door frame  150  formed by a top frame side  150   a , a hinge frame side  150   b , and a strike plate frame side  150   c . In use, the door frame  150  is positioned around the perimeter of a door opening provided in a wall  600 . 
     The frames sides  150   a - c  of door frame  150  may have different cross-sectional profiles tailored to their position within the door frame  150 . However, in other embodiments, the frame sides  150   a - c  have the identical profile, an example of which is shown in  FIG. 4 . In such embodiments, a single frame member bearing the profile may be formed and then cut to the desired length to serve as the top frame side  150   a , hinge frame side  150   b , and/or strike plate frame side  150   c . The door frame  150  may have a rear side  155  that is adjacent the wall or drywall  600  when the trimless door frame assembly  100  is installed and flanges  156  that wrap around or about the wall or drywall  600 . The door frame  150  may also include a hardware recess  160  with associated clearance gap  165 , an assembly recess  152 , and a door stop recess  170  with associated projections  175 . The various recesses and features of the door frame  150  are configured to accept or receive the flush mount plate  200 , floating door stop  250 , support plate  300 , and any additional parts or hardware as described below. 
       FIG. 5  is a schematic end view of a flush mount plate  200  with arms  210 . The arms  210  of the flush mount plate  200  are configured to mate with the hardware recess  160  of the frame sides  150   a - c  so that the face surface  201  of the flush mount plate provides a level surface with other components or hardware that are installed in or near the hardware recess  160 . In certain embodiments, the flush mount plate  200  may be used as a spacer or stacking component in the construction of a trimless door frame assembly  100 , as described in more detail below. 
       FIG. 6  is a schematic end view of the door stop frame  252  of a floating door stop  250 , which may include a silencer recess  255  configured to receive a door silencer  260  (shown in  FIGS. 8-12, 14, and 15 ), an optional hollow  275  for lightness, reduction in material usage, and/or ease of manufacturing, one or more absorber recesses  265  configured to receive absorbers  270  (shown in  FIGS. 8-12, 14, and 15 ), and one or more locator arms  280  with optional extensions  281 . The door stop frame  252  may also include a strike face  251  as the region of contact between a door and the floating door stop  250 . The absorber recesses  265  are configured to receive an absorber (not shown) that forms the point of contact and connection between the floating door stop  250  and door frame  150 . The locator arms  280  and/or extensions  281  are adapted to mate with the door stop recess  170  of the door frame  150 , and the width W is sufficiently small to allow for clearance and lateral movement of the floating door stop  250  with respect to the door stop recess  170  of the door frame  150 . 
       FIG. 7  is a schematic end view of a support plate  300  that may comprise one or more protrusions  310 . The support plate  300  and its associated protrusions  310  are configured to mate with the contours of the hardware recess  160  of the door frame  150 . In certain embodiments, the trimless door frame assembly  100  may not include structural supports for hinges, strike plates, and other door hardware as with traditional door frames. The support plate  300  may be installed on the door frame  150  to provide hard mounting points for hinges, strike plates, or other door hardware. Similar to the flush mount plate  200 , the support plate  300  may be used alone or in conjunction with the flush mount plate  200  to stack components in the hardware recess  160  during construction of a trimless door frame assembly  100 . 
       FIGS. 8-11  are sectional end views of a hinge frame side  150   b  and strike plate frame side  150   c  with flush mount plates  200 , floating door stops  250 , support plates  300 , and additional hardware as typically installed to a hinge side stud  151   b  and plate side stud  151   c , respectively. The frame side  150   b ,  150   c  may be affixed or otherwise attached to a stud  151   b ,  151   c  with drywall screws  153  that pass through the flanges  156  and wall or drywall  600  into the studs  151   b ,  151   c . The flanges  156  may overlap the wall or drywall  600  to varying degrees to adjust the amount of spacing between the rear side  155  of the frame side  150   b ,  150   c . The spacing between the rear side  155  of the frame side  150   b ,  150   c  may be used to compensate for variations in the size or trueness of the wall opening. The frame side  150   b ,  150   c  may then be adjusted to be plumb with respect to the ground and adjacent frame sides  150   a - c . In certain embodiments, the flanges may be left exposed, painted, anodized, or covered with mud, sanded, and painted to match the drywall to provide a smooth and clean appearance. In some embodiments, a decorative reveal  180  may be included in the frame side  150   b ,  150   c.    
     A floating door stop  250  may be positioned along the length of each frame side  150   a - c  and more particularly is positioned within the door stop recess  170  on each frame side  150   a - c  and retained therein via locator arms  280 . The floating door stop  250  may include a door silencer  260  positioned within silencer recess  255  on the strike face  251  of the door stop frame  252 . The door silencer  260  may be formed of a gasket material, such as a rubber or other elastomeric material. One exemplary gasket material for the door silencer is a thermoplastic vulcanizate (TPV) material. The door silencer  260  acts to seal the door  500  (not shown) against the floating door stop  250  and silences the door  500  as it closes against the floating door stop  250 . The locator arms  280  may interact with the projections  175  of the door stop recess  170  to allow a loose-fit between the floating door stop  250  and door stop recess  170 . As shown, the locator arms  280  have clearance around their ends to allow the floating door stop  250  to move laterally relative to the door stop recess  170 . In certain embodiments, the locator arms  280  may have different end configurations to allow for additional degrees of freedom. For example, as shown in  FIGS. 8-11 , the locator arms  280  allow for relative movement between the floating door stop  250  and door stop recess  170 , and subsequently the frame side  150   b ,  150   c , in the direction perpendicular to the strike face  251  of the floating door stop  250 . However, the locator arms  280  have extensions  281  that restrict relative movement between the floating door stop  250  and door stop recess  170  in a direction parallel to the strike face  251  of the floating door stop  250 . In some embodiments, the locator arms  280  may not have the extensions  281  or otherwise be designed to allow for relative movement between the floating door stop  250  and door stop recess  170  in a direction parallel to the strike face  251  of the floating door stop  250 . Certain embodiments of the floating door stop  250 , locator arms  280 , extensions  281 , door stop recess  170 , and/or projections  175  may be configured to allow for relative movement between the floating door stop  250  and door stop recess  170  in one, two, or three dimensions, including rotation about any given axis. 
     The floating door stop  250  may also include one or more absorbers  270  positioned within or proximate to the door stop frame  252  and more particularly within the absorber recesses  265  of the door stop frame  252 . The absorbers  270  may be a spring or a component made from rubber, an elastomer, cellular material, a polymer, a thermoplastic vulcanizate, or any other material selected for its ability to deflect, compress, or elongate and regain its shape to absorb and distribute forces. The absorbers  270  function to stabilize the floating door stop  250  in an aligned position within door stop recess  170  of a frame side  150   a - c . When the floating door stop  250  encounters a force, such as when a door is closed against the strike face  251  of the door stop frame  252 , the floating door stop  250  will be laterally displaced relative to the door stop recess  170 , which compresses the absorber  270  distal the strike face  251  into a projection  175  of the door stop recess  170  such that the absorber  270  absorbs the energy of the door closure instead of the surrounding wall. More specifically, the motion and/or displacement of the floating door stop  250  distributes the impact of a door closure or other applied force over a larger amount of time as the absorber  270  deflects and extends the range of motion of the floating door stop  250 . The impact energy applied through the floating door stop  250  extends over a larger time with a correspondingly lower peak force. Also, the internal friction and deflection of the absorber  270 , along with any frictional losses due to the movement of the floating door stop  250  relative to any other parts of the frame side  150   b ,  150   c  may absorb and dissipate impact energy. The resulting force transferred through a trimless door frame assembly  100  to the studs  151   b ,  151   c  and wall or drywall  600  has a much lower peak magnitude relative to solidly mounted door stops. These lower peak forces greatly reduce the chances of cracking or fatigue, particularly of the wall or drywall  600  at or around the frame sides  150   a - c  and/or drywall screws  153 , even through repeated cycles of opening and closing the door. While the floating door stop is shown equipped with two absorbers  270 , it is certainly contemplated to use a single absorber  270  or more than two absorbers  270 . 
     The floating door stop  250  may include any number of modifications or alterations to suit a particular application. For example, as shown in  FIGS. 9-11 , an auxiliary absorber  271  may be included in the door stop recess  170  to support or otherwise cushion one or more of the locator arms  280  or extensions  281 . As shown, the auxiliary absorber  271  is disposed between the locator arm  280  and the door stop recess  170  on the opposite side of the floating door stop  250  as the strike face  251 . This auxiliary absorber  271  may be particularly beneficial for absorbing the forces associated with closing of a door. Furthermore, absorbers  270  and/or auxiliary absorbers  271  may be positioned in any orientation or relation between the floating door stop  250 , locator arms  280 , and or extensions  281  and the door stop recess  170 , projections  175 , and/or frame sides  150   a - c.    
     In order to adjust or optimize the amount of force absorption for a particular application, the floating door stop  250  (with absorber(s)  270  and optional auxiliary absorbers  271 ) may take on different materials, geometries, or characteristics. For example, the absorbers  270  or auxiliary absorbers  271  may be hollow or solid, and may be made from any material that is suitable for its characteristics to compress, deflect, or elongate in response to an applied load over a large number of loading cycles. In some embodiments, the absorber  270  and/or auxiliary absorber  271  may be cast or otherwise molded in place within the absorber recesses  265  or between the floating door stop  250 , locator arms  280 , extensions  281 , door stop recess  170 , and/or projections  175 . In certain embodiments, the absorbers  270  and/or auxiliary absorbers  271  may be asymmetrical so as to better adapt to differing levels of force applied in different directions. The absorber  270  and/or auxiliary absorber  271  may also be affixed or otherwise attached to the floating door stop  250 , locator arms  280 , extensions  281 , door stop recess  170 , and/or projections  175  by adhesives, directly molding the absorbers  270  and/or auxiliary absorbers  271  to a surface, or forming the absorbers  270  and/or auxiliary absorbers  271  in such a shape as to allow them to accept tensile loads between the floating door stop, locator arms, and/or extensions  281  and the door stop recess  170  and/or projections  175  in addition to compressive loads. 
     Referring to  FIG. 8 , a hinge frame side  150   b  may also include a hinge  320  coupled to a support plate  300 . The support plate  300  is installed in the hardware recess  160  of the hinge frame side  150   b . In certain embodiments, the support plate  300  may be slid along the length of the hinge frame side  150   b  to the appropriate location for mounting the hinge  320 . As shown, the hinge  320  may be attached to a support plate  300  with standard fasteners  305 . In certain embodiments, the fasteners  305  may be sufficiently long that they extend into the clearance gap  165 . 
       FIGS. 9 and 10  are sectional views of a hinge frame side  150   b  adapted for use with concealed hinges  321  taken above and below the concealed hinge  321 , respectively. Concealed hinges  321  may be substantially larger than traditional hinges, and may extend farther into the hinge frame side  150   b  such that they impinge upon the hinge side stud  151   b  and/or wall or drywall  600 . Notches or other clearance apertures (not shown) must be cut into the hinge frame side  150   b , hinge side stud  151   b , and/or wall or drywall  600  to provide adequate clearance and space for the concealed hinge  321 . In some embodiments, the weakening of the wall or drywall  600 , hinge side stud  151   b , and/or frame side  150   b  may require the use of a secondary hinge side stud  322  affixed to the primary hinge side stud  151   b  with an optional stud screw  154 . The concealed hinge  321  may be affixed or otherwise attached to a concealed hinge support plate  301  with bolts  306  or other fasteners. The concealed hinge support plate  301  mates with hardware recess  160 . The vertical positioning of the concealed hinge support plate  301 , and consequently the concealed hinge  321 , may be adjusted by stacking the concealed hinge support plate  301  in the hardware recess  160  with different lengths of flush mount plates  200 . The flush mount plates  200 , which may interact with the hardware recess  160  through arms  210 , may provide vertical support to the concealed hinge support plate  301 , and, as shown in  FIG. 10 , provide a flush, aesthetically pleasing surface when face surface  201  is coplanar with one or more other portions or features of the hinge frame side  150   b  and/or any other adjacent hardware. In certain embodiments, the flush mount plates  200  may be notched or cut to conform to the edge contours of a standard hinge  320 , concealed hinge  321 , or any other hardware that may impinge on the flush mount plates  200 . 
       FIG. 11  is a sectional end view of a strike plate frame side  150   c  as installed with a strike plate  340 . The strike plate  340  is attached to a support plate  300  by one or more fasteners  305 . The support plate  300  is disposed within the hardware recess  160  of strike plate frame side  150   c . The vertical location of the support plate  300 , and the attached strike plate  340 , may be adjusted by stacking the support plate  300  in the hardware recess  160  with differing lengths of flush mount plates  200  (not shown). The flush mount plates  200  may be notched or otherwise cut or shaped to fit the contours of the strike plate  340  or any other hardware that may be in the vicinity of the flush mount plates  200 . 
       FIGS. 12A-C  are assembly views of exemplary embodiments of the hinge frame side  150   b , top frame side  150   a , and strike plate frame side  150   c . The frame sides  150   a - c  may be provided with a series of flush mount plates  200  interspersed with one or more support plates  300 . Each frame side  150   a - c  may also include a door stop frame  252  with a door silencer  260  and absorber  270 . One exemplary method of installing the flush mount plates  200 , support plates  300 , door stop frames  252 , door silencers  260 , and/or absorbers  270  comprises sliding the individual parts into their respective recesses or channels of the frame side  150   a - c  by aligning the part at the end of a recess and simply feeding it through. 
     As shown in  FIG. 12B , the flush mount plate  200  and door stop frame  252  (with door silencer  260  and/or absorber  270 ) may be the same length as the top frame side  150   c  so that only one component of each is required to span the length of the top of the door frame  150 . However, the flush mount plate  200  and door stop frame  252  (with door silencer  260  and/or absorber  270 ) may also be provided in multiple sections or pieces to facilitate installation, or to interact with other components of the trimless door frame assembly  100 . For example, the hinge frame side  150   b  may require one or more support plates  300  to provide mounting points for one or more hinges  320 . The flush mount plates  200  and support plates  300  may be installed in series such that the flush mount plates  200  establish the vertical location and/or support for the support plates  300 . The positioning of the support plates  300  may be adjusted or otherwise altered by cutting the flush mount plates  200  to length and stacking the flush mount plates  200  and support plates  300  in order in the hardware recess  160  of the hinge frame side  150   b . The hinges  320  may then be affixed or otherwise attached to the support plates  300  in any vertical position as necessary for a particular application. 
     Similarly, the strike plate frame side  150   c  may include a strike plate  340  affixed or otherwise attached to a support plate  300 . The flush mount plates  200  may be cut to length and stacked in the hardware recess  160  of the strike plate frame side  150   c  along with the support plate  300  to vertically locate the support plate  300  and strike plate  340 . In certain embodiments, the flush mount plates  200  may be notched, cut, or otherwise shaped to conform to the peripheral contours of a hinge  320 , strike plate  340 , or any other hardware that may be in contact with the flush mount plates  200 . 
     Once the required components have been installed into individual frame sides  150   a - c , the frame sides  150   a - c  may be connected with angle brackets  350  to form the door frame  150 . The angle brackets  350  may be installed into assembly recesses  152  to connect the top frame side  150   a  with the hinge frame side  150   b  and strike plate frame side  150   c  on either side, respectively. 
     To further describe the operation and interaction of the flush mount plate  200 , support plate  300 , hinges  320 , and/or strike plate  340 , an exemplary installation method of strike plate frame side  150   c  is described. A first flush mount plate  200  is first inserted longitudinally into the hardware recess  160  (not shown) and slid along strike plate frame side  150   c  until the bottom of the flush mount plate  200  rests against the floor. As shown in  FIG. 12C , the upper edge of the flush mount plate  200  towards the bottom of the figure may be notched such that it conforms to the strike plate  340 . This notch, and others, would typically be made prior to taking the strike plate frame side  150   c  to the installation location, but they may also be made on-site. In other words, the flush mount plate  200  pieces are typically, but do not have to be, pre-cut. Next, a support plate  300  is inserted longitudinally into the hardware recess  160  and slid along the strike plate frame side  150   c  until it abuts the first flush mount plate  200 , which prevents further translation of the support plate  300  within hardware recess  160  and locks support plate  300  in position. This position is where the strike plate  340  will be located. A second flush mount plate  200  is then inserted into hardware recess  160  and slide along strike plate frame side  150   c  as described above until it abuts the support plate  300 . The strike plate  340  can then be secured (e.g., screwed) into the support plate  300 . A similar assembly method is performed for the hinge frame side  150   b , although this side may involve the installation of more flush mount plates  200  and support plates  300  depending on the number of hinges  320  used. The assembly of the top frame side  150   a  may be simpler, as there may not be hinges  320  or strike plates  340 , and only a single flush mount plate  200  having substantially the same length as the top frame side  150   a  need be inserted into hardware recess  160 . In much the same way, the floating door stop  250  may be installed into the frame sides  150   a - c  by aligning the floating door stop  250  with the end of the door stop recess  170 . The floating door stop  250  may then be slid along the door stop recess  170  until it is fully installed within the frame side  150   a - c.    
       FIG. 13A  is an assembly view of a hinge frame side  150   b  and strike plate frame side  150   c  with concealed hinges  321 . The assembly of the strike plate frame side  150   c  may be similar to that described above, with a strike plate  340  mounted to a support plate  300 , which is located by flush mount plates  200 . The assembly of hinge frame side  150   b  may be altered or changed to support the use of concealed hinges  321  that are considerably larger and bulkier than traditional hinges. To accommodate concealed hinges  321 , the hinge frame side  150   b  may include hardware apertures  162 . The concealed hinge support plates  301 , as shown in  FIG. 13B , may include protrusions  311  for aligning and/or locating the concealed hinge support plate  301  in the hinge frame side  150   b , a cavity  312 , hinge aperture  314 , and fastener holes  316 . The cavity  312  and hinge aperture  314  may be configured to accept the concealed hinge  321  so that it may be affixed or otherwise mounted to the concealed hinge support plate  301  via fastener holes  316 . Similarly, flush mount plate  200  may also include apertures  215  to provide clearance for the concealed hinges  321 . As shown, the flush mount plate  200  may be a single piece or may be separate pieces as described above. A single piece flush mount plate  200  may be installed by sliding it into the hardware recess  160 , before or after the installation of the concealed hinge support plates  301 . 
     Referring to  FIGS. 12A-C  and  13 A, the trimless door frame assembly  100  may take on a number of variations or alternative embodiments. For example, trimless door frame assemblies  100  may be fully or partially assembled in a factory or other production facility, including any necessary trimming or shaping of the flush mount plates  200  or any other parts, and installed on site. Alternatively, trimless door frames assemblies  100  may be provided as kits, as individual components cut to length, individual components provided in stock lengths and cut on site, or as bulk lengths of stock material to be cut into individual components on site. In any embodiment, features such as, but not limited to, hardware apertures  162 , apertures  215 , length, notches, or the like may be cut or formed either in a manufacturing facility or on site during door installation. Furthermore, components such as the flush mount plates  200 , door stop frames  252 , door silencers  260 , absorbers  270 , support plates  300 ,  301  or the like may be installed by snapping them into place, retaining them with fasteners or adhesives, or sliding them into the applicable recesses as described above. Certain embodiments of the trimless door frame assembly  100  may include the floating door stop  250  and its associated hardware on only the top frame side  150   a , hinge frame side  150   b , strike plate frame side  150   c , or any combination thereof. 
       FIGS. 14 and 15  are perspective views of the hinge frame side  150   b  and strike plate frame side  150   c . The frame sides  150   b ,  150   c  include a floating door stop  250  with door stop frame  252 , door silencer  260 , and absorbers  270 . The hinge frame side  150   b  has a hinge  320  disposed on mounting plate  300  and between two flush mount plates  200 . Similarly, the strike plate frame side  150   c  has a strike plate  340  installed on mounting plate  300  and between two flush mount plates  200 . As shown, the flush mount plates  200  have a face surface  201  that is coplanar with the hinge  320  and/or strike plate  340 . The flush mount plates  200  may also be notched or otherwise shaped to mate with the contours of the hinge and/or strike plate  340  to provide a relatively flat visible surface. 
       FIG. 16  is a perspective view of the trimless door frame assembly  100  as assembled from a top frame side  150   a , hinge frame side  150   b , and strike plate frame side  150   c . The flush mount plates  200  and hinges  320  are visible on the hinge frame side  150   b . The frame sides  150   a - c  have been assembled by inserting angle brackets  350  into the assembly recesses  152  (not shown). The frame sides  150   a - c  may be assembled into a trimless door frame assembly  100  in a wall or wall frame, or they may be assembled and then installed into a wall or wall frame.

Summary:
Described are trimless door frames and energy absorbing door stops. The energy absorbing door stop allows for relative movement between the door stop and the surrounding door frame. The relative movement of the energy absorbing door stop helps to distribute and dissipate forces and vibrations from opening and closing a door, reducing the levels of force transferred into the surrounding wall. The reduction in forces applied to the wall allows for the elimination of heavy door framing and trim. Since door trim is no longer necessary, trimless door frames may be installed with a smooth appearance without cracks appearing in the surrounding wall due to stress or fatigue.
