DETAILED DESCRIPTION

[0026] Various aspects of the present disclosure will be described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to promote a thorough understanding of one or more aspects of the present application. It may be evident in some or all instances, however, that any aspects described below can be practiced without adopting the specific design details described below.

[0027] As will be described fully below, the present disclosure may be configured to correct a door bottom gap by inserting a channel assembly into a gap between the bottom edge of a door and a finished floor beneath the door, and attaching the channel assembly to the bottom edge of the door. In so doing, the present disclosure may extend the height of the door, thereby reducing the gap at the bottom of the door. For example, if such a gap measures 1.375″ across the width of the door, the channel assembly of the present disclosure, which may measure 1.0″ in height, and. upon installation to the bottom of the door, may add 1.0″ to the effective height of the door and therefore reduce the door bottom gap to 0.375″. The 0.375″ dimension may be within the 0.75″ dimension currently allowed by relevant regulation code for fire-rated doors.

[0028] In another embodiment, the present disclosure may be configured to control uneven door bottom gaps across the width of the door via at least one moving component of the channel assembly. In one aspect, the moving part may be set on a pre-determined location via one or more end caps, thereby dynamically changing the height of the channel assembly. It a door bottom gap measures 1.375″ on one side of the door and 1.0″ on the other, the end caps may be used to set the moving part on an angle, thereby accommodating the uneven floor condition. In all cases, the moving part may be free to move to accommodate high spots or other obstructions encountered during the swinging motion path of the door during operation.

[0029] In accordance with important aspects of the present disclosure, the moving component: of the Channel assembly may be configured to provide a selected height ranging from a maximum (across the width of the door) of 1″ (full extension condition) and a minimum (across the width of the door) of 0.625″ (full compression condition). As will be described hilly below, an example channel assembly of the present disclosure may include a top channel, a V-shaped bottom channel and a formed spring. The internal moving component may be the V-shaped bottom channel, and the configuration of the channel assembly may provide for a constrained motion path (travel distance) of the V-shaped bottom channel within the top channel. The formed spring, which connects the top channel to the V-shaped bottom channel, may be configured to apply a downward force: onto the V-shaped bottom channel, yet allow the V-shaped bottom channel to operate within a motion path as allowed for by the respective parts' geometry. That is, the channel assembly of the present disclosure provides a motion path the the V-shaped bottom channel to freely operate in a substantially vertical motion path, or alternatively one that may be at an angle. As a result, the motion path may be configured to accommodate either a gap that is uniform across the width of a door, or a gap that varies from one side of the door to the other.

[0030] In one embodiment, to provide a pre-set height location from one side of the door to the other (other than that of full extension of the channel assembly), one or more end caps may be used in addition to the channel assembly. For example, each end cap may be generally L-shaped with one vertical portion installed on the outer surface of a door edge and the horizontal portion inserted into the space between the top channel and the V-shaped bottom channel. Each end cap may be used to retain the V-shaped bottom channel at a fixed position relative to a gap between its horizontal portion and the finished floor. As discussed above, door bottom gap dimension may be uniform or inconsistent across the width of the door. When the end caps are used and the pre-set height is greater than the (full compression state of the formed spring) height of the channel assembly, the V-shaped bottom channel may be allowed to move within the top channel. The motion path of the V-shaped bottom channel may also provide a means of clearance (temporarily reducing the effective height of the channel assembly) should the V-shaped bottom channel make contact with a high spot in the finished floor. When a high spot or obstruction is encountered, the. V-shaped bottom channel may move to a position within the top channel, until the moment that the high spot is no longer present (during a swing operation of the door), then the V-shaped bottom channel returns to the pre-set height location, due to the downward force applied. by the formed spring.

[0031] Among other features, the present disclosure may include a fire-rated door assembly. Which may contain a listed and labeled fire rated frame, a listed and labeled fire rated single-swing door and a listed and labeled fire rated smoke seal gasket set it is known in the art that excessive clearance gaps around the perimeter of the door may be brought into compliance by using a stop extender, attached to the frame. However, there .is a need for a different solution when an assembly contains a door that is compliant around the perimeter but non-compliant at the door bottom.

[0032] Regarding the gap at the door bottom, a few elements factor into the effectiveness of the disclosed method and apparatus. First, the gap between the door bottom and the finished floor is often not a consistent dimension across the width of the door. Second, the finished floor condition is often not consistent and there may exist high spots in the finished floor which may reduce the gap dimension at a particular location in the swinging action of the door. Furthermore, the listed and labeled fire rated doors may be wood-composite (commonly containing a mineral-based core) or a hollow metal, steel door. The disclosed method and apparatus may account for these variations while providing for an aesthetic and practical solution.

[0033] FIG. 1 demonstrates a first gap condition between the bottom edge 59 of door 1 and the finished floor 57, whereby gap 3 measured at one edge 9 of door 1 may be substantially the same as gap 4 measured at the other edge 10 of door 1 As such, the gap between the bottom edge 59 of door 1 and finished floor 57 may be uniform across the width dimension 2 of door 1 (e.g., commonly measured 36″). Referring to FIG. 2, a second gap condition may exist between the bottom edge 59 of door 1 and the finished floor 58, whereby the gap 5 measured at one edge 9 may be either greater or less than the gap 6 measured at the other edge 10 of door 1. As such, the gap between the bottom edge 59 of door 1 and finished floor 58 may not be uniform across the width 2 of door 1.

[0034] In one aspect, the present disclosure may be configured to provide a solution for the gap conditions illustrated in FIGS. 1 and 2. For example, referring to FIG. 3, one embodiment may include a door bottom assembly having an L-shaped bracket 7 installed onto the bottom portion of door 1, wherein the gap condition may be uniform across the width 2 of the door 1, as shown in FIG. 1. Further, referring to FIG. 4, another embodiment may include a door bottom assembly having an L-shaped bracket 7 installed onto the bottom portion of door 1, wherein the gap condition is not uniform across the width 2 of the door 1, as shown in FIG. 2. In one preferred embodiment, the present disclosure may provide a solution to account for 0.375″ gap condition variance across the width 2 of the door 1. It should be appreciated that the installation of the L-bracket 7 on the door 1 may allow for the installation of the entire door bottom assembly of the present disclosure onto the bottom portion of the door 1 while the door 1 is hanging on its hinges. In certain implementations, the L-shaped bracket 7 may be optional where the door 1 may be taken down (off the hinges) so that access to the bottom edge of the door 1 is available to insert the fasteners or other attachment components.

[0035] As will be described fully below, one example system for controlling or managing door bottom clearance for a fire-rated door may include a channel assembly 11, end caps 21 and an L-shaped bracket 17, in accordance with aspects of the present disclosure. Referring to FIG. 5, an example channel assembly 11 may include a top channel 12, a V-shaped bottom channel 13, and a formed spring 15 with its topmost end affixed to an underside of the top channel 12 by a rivet 14. As shown in FIGS. 5 and 6, the channel assembly 11 of the present disclosure may have a substantially vertical motion path 16, wherein the V-shaped bottom channel 13 may be fully or partially contained within the space defined by the top channel 12. FIG. 5 shows the channel assembly 11 in a fully extended position, wherein the bottom face 41 of each co-planar tab 40 of the V-shaped bottom channel 13 makes resting contact with the inside face 30 of the co-planar tab 28 of the top channel 12, as shown in FIGS. 9D and 10D. Referring to FIG. 6, the channel assembly 11 is shown to be in a fully compressed position, thereby resulting in a travel distance 23 of the V-shaped bottom channel 13 between the bottom face 41 and the inside face 30. That is, the V-shaped bottom channel 13 may be configured to move relative to the top channel 12 along a substantially vertical motion path 16 which may be controlled by a down pressure exerted onto the V-shaped bottom channel 13 by the formed spring 15. As shown in FIGS. 12C, 13A and 13B, the formed. spring 15 may be retained by the engagement of a protrusion 46 located on the formed spring 15, opposite the end 47, and captured within of opening 44 of spring receiver 43. The spring receiver 43 may be welded into the V-shaped bottom channel 13, as shown in FIGS. 12A and 12C, thus providing the retaining mechanism for the protrusion 46. FIG. 12B illustrates a side perspective view of the V-shaped bottom channel 13 with spring receivers 43 welded within. In one embodiment, as shown in FIG. 12A, two spring receivers 43 may be welded within the V-shaped bottom channel 13, each spaced at a distance of 4″ from the respective ends of V-shaped bottom channel 13 in order to leave a distance or spacing between the two spring receivers 43 measuring 25.375″. This spacing may provide for the spring action to be biased toward the outer edges of channel assembly 11, providing for the proper motion path 16 as previously described.

[0036] In an example implementation, the channel assembly 11 of the present disclosure may be configured to include the top channel 12 connected with the V-shaped bottom channel 13, via the formed spring 15. Initially, the formed spring 15 may be compressed, such that the end of the formed spring 15 containing the protrusion 46 may rest against the top channel 12. Subsequently, the V-shaped bottom channel 13 may be configured to move into the space defined by the top channel 12, such that the protrusion 46 aligns with the opening 44 of the spring receiver 43, as shown in FIG. 11. The compression on the formed spring 15 may be released allowing the protrusion 46 to rest securely within the opening 44 of the spring receiver 43.

[0037] FIGS. 3, 4, 7A, 7B and 7C illustrate multiple perspective views of the channel assembly 11 including an L-shaped bracket 17 assembled onto a door 1 for controlling or managing door bottom clearance, in accordance with aspects of the present disclosure. Referring to FIG. 7B, the channel assembly 11 may be attached to the L-bracket 17 using one or more fasteners 20 inserted through one or more holes 54 which are located on a long leg 56 of L-bracket 17, as shown in. FIGS. 15A, 15B, and 15D. Next, the channel assembly 11 may be positioned on the bottom edge 59 of the door 1 as shown in FIGS. 1 and 2, and the L-bracket 17 may be attached to a selected outer face 60 of the door 1 via fasteners 18 inserted through one or more holes 53 which are located on a short leg 55 of the L-shaped bracket 17, as shown in FIGS. 15A, 15B and 15C. In one embodiment, referring to FIG. 7A, two end caps 21 may be installed on two narrow ends of the door 1 (e.g., one on edge 9 and one on edge 10 of door 1, as shown in FIGS. 1-4). Referring to FIGS. 14A, 14B, 14C and 14D, each end cap 21 may be generally L-shaped including a vertical portion 49 placed on the outer surface of one narrow end of the door 1 and a horizontal portion 48 inserted into the space between the bottom edge of door 1 and the finished floor. In one embodiment, the horizontal portion 48 may be configured to include one or more tabs 50 that may be implemented and inserted into the space defined by the top channel 12, orthogonal to the travel distance 23 described in connection with FIG. 6, thereby controlling the amount of travel along the motion path 16 of the V-shaped bottom channel 13. As shown is FIGS. 7C and 1413, one or more fasteners 19 may be initially installed into slot 51 of each end cap 21 until a desired position is determined. Thereafter, fasteners 19 may be installed into corresponding through holes 52 of each end cap 21 for secure attachment to the edges of door 1.

[0038] Alternatively, another example system for controlling or managing door bottom clearance for a fire-rated door may include a channel assembly 11 and end caps 21, in accordance with aspects of the present disclosure. Referring to FIG. 8.B, the channel assembly 11 may be initially positioned on the bottom edge 59 of the door 1, and one or more fasteners 22 may be inserted through slotted openings 29 of the top channel 12 of the channel assembly 11 to securely attach the channel assembly 11 on the bottom edge 59 of the door 1. Next, referring to FIG. 8A, two end caps 21 may be installed on two narrow ends of the door 1 (e.g., one on edge 9 and one on edge 10 of door 1, as shown in FIGS. 1-4). Referring, to FIGS. 14A, 14B, 14C and 14D, each end cap 21 of this embodiment may be generally L-shaped including the vertical portion 49 placed on the outer surface of one narrow end of the door 1 and the horizontal portion 48 inserted into the space between the bottom edge of door 1 and the finished floor. For example, the horizontal portion 48 may include one or more tabs 50 inserted into the space defined by the top channel 12, orthogonal to the travel distance 23 described in connection with FIG. 6, thereby controlling the amount of travel along the motion path 16 of the V-shaped bottom channel 13. In one embodiment, each of tabs 50 may be sized to position between the co-planar tabs of the top channel 12 and the V-shaped bottom channel 13 and between the vertical walls (slabs) of the top channel 12 and the V-shaped bottom channel 13, respectively. As shown is FIGS. 8C and 14B, one or more fasteners 19 may be initially installed into slot 51 of each end cap 21 until a desired position is reached. Thereafter, fasteners 19 may be installed into corresponding through holes 52 of each end cap 21 for secure attachment to the edges of door 1.

[0039] In some alternative embodiments, the end caps 21 may be optional where a selected height may be desired other than that of a full extension of the V-shaped bottom channel 13. That is, the end caps may be used to set a pre-set height that may be different on one side of the door than the other. The pre-set height locations of the end caps on either side of the door may be independent of each other, and therefore may be used to position the V-shaped bottom channel 13 within the top channel 12, at a position that ranges from a maximum (full extension) on one side to a minimum (full compression), or any location therebetween. In certain implementations, the end caps 21 may accommodate high spots in the floor or other obstructions encountered during the swinging motion of the door importantly, the end caps 21 may be configured to provide a motion path of the V-shaped bottom channel 13 within the top channel 12 which allows for the option of different pre-set heights to be set, and allows for the V-shaped bottom channel 13 to be set at an angle (across the width of the door).

[0040] Referring now to FIGS. 9A, 9B and 9C, in one preferred embodiment, the top channel 12 of the channel assembly 11 of the present disclosure may be made of 18 gauge steel (e.g., 0.048″ in thickness) and formed into a rectangular in shape, containing a width dimension 32 of 1.50″ and a height dimension 31 of 0.625″ and a length dimension 33 of 35.5″. Referring to FIG. 9D, one of the widest top side 27 of the top channel 12 may include mounting multiple holes 24 and slotted openings 29, while the opposite side may include an open distance 26 which may measure 0.75″ and may be located symmetrical about a centerline 25. The open distance 26 may result in two co-planar tabs 28, each including an inside face 30.

[0041] In accordance with aspects of the present disclosure, the V-shaped bottom channel 13 of the channel assembly 11 may be made of 18 gauge steel and formed into a symmetrical geometry about a centerline 42, as shown in FIG. 10D. In one embodiment, the V-shaped bottom channel 13 may include a V-shape portion 35 at the bottom and connected with two co-planar tabs 40 on both side of the centerline 42 via two vertical slabs, respectively. Each co-planar tab 40 may include a bottom thee 41. In one embodiment, the width dimension 37 of the V-shaped bottom channel 13 may measure 1.375″ and the width dimension 45 of the V-shape portion 35 may measure 0.625″ and the overall length 39 of the V-shaped bottom channel 13 may measure 35.375″. These width dimensions are critical to the interaction within the top channel 12 upon assembly into the channel assembly 11. In one preferred embodiment in connection with FIGS. 5 and 6, the width dimension 37 of V-shaped bottom 13 (1.375″) may be less than the inside width of the top channel 12, created by subtracting twice the 18 gauge material thickness (2×0.048″) from width 32 (1.50″)=1.40″. Additionally, as shown in FIG. 10D, width dimension 45 (0.625″) of the V-shaped portion 35 may be less than the open distance 26 (0.75″) of the top channel 12. These dimensions provide for an unobstructed motion path of V-shaped bottom channel 13 within the top channel 12, controlled by spring 15. Moreover, the height 38 of the channel assembly 11 may measure 0.375″ which may be critical to the interaction within the top channel 12 as this dimension may control the travel distance 23, which measures 0.375″. Lastly, as shown in. FIGS. 1013 and 10C, a plurality of through holes 36 (e.g., each may measure 0.3125″ in diameter) may be located along the centerline 42 on the V-shaped portion 35. Referring to FIG. 11, the spring receiver 43 may be made of 18 gauge steel and measure 1″ in length and the width is matched to the inside dimension of the V-shaped portion 35 of the V-shaped bottom channel 13. The opening 44 may be a slot which measures 0.25″×0.4375″. Referring to FIGS. 13A and 13B, the formed spring 15 may be made from 0.03″ thick spring steel, measuring 0.375″ wide and formed with two bends, resulting in two parallel ends. In one embodiment, one end 47 may include two through holes 61 which are 0.125″ in diameter, and the opposite end may include a protrusion 46 which measures 0.125″ diameter and 0.25″ in height. Referring to FIGS. 14A, 1413, 14C and 14D, each end cap 21 may be formed from 16 gauge steel into a 90° angle, measuring 1.375″ wide and 20″ in height, with a horizontal portion 48 and a vertical portion 49. In one embodiment, the horizontal portion 48 may include three, 0.5″ long tabs with two recesses between. The vertical portion 49 may include contain a slot 51 and two through holes 52. In one preferred embodiment, the slot 51 may measure 0.156″×0.75″ and each through hole 52 may measure 0.156″ in diameter.

[0042] In accordance with aspects of the present disclosure, an example assembly to a listed and labeled tire rated door may include using an L-shaped bracket (e.g., the L-shaped bracket 17 described above in connection with FIGS. 7A and 7B) to attach to the bottom portion of a listed and labeled fire rated door for controlling or managing door bottom clearance purposes. To illustrate the option of using an L-shaped door bracket, the installation instruction for both a listed and labeled fire rated wood door and hollow metal, steel door are explained below.

[0043] Among other features, an example method of attachment fir listed and labeled lire rated wood doors without using an .L-shaped bracket is as follows: [0044] 1. Open the package and identify the proper mounting hardware (#10×2″ screws). [0045] 2. Lay the removed door on a horizontal surface such as a work table or saw horses. [0046] 3. Place a component (e.g., the channel assembly 11 described above) onto the bottom of the door, holding flush at one edge and measuring any gap (if any) on the other edge. [0047] 4. Check the width of the component and trim to width, up to 2″ per side, as necessary. [0048] 5. With the component at the appropriate width, center across the bottom of the door. Hold in this position and transfer the hole locations from the moveable portion of the component, onto the door bottom. [0049] 6. Remove the component and drill a 7/64″ pilot hole 2″ deep. [0050] 7. Ensure the faces of the door and door bottom are clean and free from debris. [0051] 8. Install the #10×2″ screws into the holes, leaving approximately ¼″ of the screw out of the door bottom. [0052] 9. Install the component by placing the large diameter holes over the head of the screw and sliding the component (along the slot in the channel that attaches to the door bottom) until the head of the screw is visible through the hole in the moveable portion of the component (same holes used in earlier step to transfer hole location onto door bottom). [0053] 10. Ensure the component is positioned (side-to-side) between the edges of the door at the desired location, and then drive the #10×2″ screws until the disclosed assembly is tight against bottom of the door. [0054] 11. Set the undercut position so that bottom of the component is ⅜″ above the finished floor, using the end cap plates. Place a shim of the desired thickness under the floating portion of the component install the two tabs of the end cap plates under the formed channel of the moveable portion of the component. Hold in this position and secure the end cap plates to the edge of the door using the #6×¾″ screws.

[0055] In accordance with aspects of the present disclosure, another example method of attachment fir listed and labeled fire-rated hollow metal, steel doors using an L-shaped bracket (e.g., the L-shaped bracket I described above in connection with FIGS. 7A and 7B) is as follows: [0056] 1. Open the package and identify the proper mounting hardware (#8-32 thru-bolts and #6 TEK screws). [0057] 2. Open the door with excessive gap at the bottom for access to the full door width. [0058] 3. Slide a component (e.g., the channel assembly 11 described above) onto the bottom of the door, holding flush at one edge and measuring any gap if any) on the other edge. [0059] 4. Check the width of the component and door bracket, and trim to width up to 2″ per side, as necessary. [0060] 5. Assemble the door bracket to the component using the #6 TEK screws and the holes provided in the door bracket. Take caution to locate the screws to not interfere with the spring within the component. [0061] 6. With the component and door bracket assembled and at the appropriate width, center across the face of the door. Hold in this position and transfer the hole locations in the door channel onto the face of the door. [0062] 7. Remove the component and door bracket and drill a 7/32″ diameter hole through the door. [0063] 8. Ensure the: faces of the door are clean and free from any debris. [0064] 9. Assemble the component and door bracket to the door using the #8-32 through bolts. [0065] 10. Set the undercut position so that bottom of component is ⅜″ above the finished floor, using the end cap plates. Place a shim of the desired thickness under the floating portion of the component. Install the two tabs of the end cap plates under the formed channel of the moveable portion of the component. Hold in this position and secure the end cap plates to the edge of the door using the #6×¾″ screws.

[0066] Among other features, the present disclosure may achieve the following objectives: [0067] Correct a non-compliant, excessive gap condition between a door bottom and a finished floor.
