FIG. 1 is a front view drawing illustrating one embodiment of a sectional door 100. The sectional door 100 may be a garage door. The sectional door 100 includes a plurality of sections 110. A jamb 105 and a lintel 107 may be disposed adjacent the sectionals 110. A cross section 160 of the sectional door 100 is depicted in FIGS. 2A-B and 3A-B.
FIG. 2A is a top view drawing illustrating one embodiment of a section 110 and a jamb 105. The section 110 and jamb 105 may be the cross section 160 of the section door 100 of FIG. 1. The section 110 and the jamb 105 are the section 110 and the jamb 105 of FIG. 1. The section 110 may be connected to a bracket 125. The bracket 125 may secure an axle 130 for a wheel 135. The wheel 135 may move within a track 140. In the depicted embodiment, the track 140 is connected to a jamb angle 144. The jamb angle 144 is secured to a jamb interior face 120 of the jamb 105 by a track fastener 146. The track fastener 146 may be a bolt, a wood screw, or the like. The sectional door 100 may be opened and closed as the sections 110 are moved along the track 140. The jamb 105 includes a jamb traverse face 115 and the jamb interior face 120.
In the past, a door seal 148 has been fastened directly to the jamb interior face 120 with a wood screw 150 or the like. Unfortunately, positioning the lengthy door seal 148 along the jamb interior face 120 and then securing the door seal 148 often results in uneven contact of the door seal 148 with the jamb interior face 120, and in breaks in the seal. For example, the door seal 148 may separate from the jamb interior face 120 because the wood screws 150 are placed too closely together relative a length of the door seal 148 between the wood screws 150. In addition, the door seal 148 may not be applied vertically plumb, reducing the effectiveness and visual attractiveness of the resulting seal.
FIG. 2B is a top view drawing illustrating one alternate embodiment of a section 110 and a jamb 105. The section 110 and jamb 105 may be the cross section 160 of the section door 100 of FIG. 1. In the depicted embodiment, the track 140 is secured to the horizontal reinforcing angle 142 by the track fastener 146. Alternatively, the track 140 may be secured to a post.
The embodiments described herein allow an under-track door seal to be applied under the jamb angle 144 and to be secured by the track fastener 146. An installer need only loosen the track fastener 146 and insert the under-track door seal to a side of the jamb angle 144. The track fastener 146 is then retightened and under-track door seal may be held in place by the track fastener 146. As a result, the under-track door seal is more rapidly and accurately installed.
In addition, the embodiments may form a seal between one or more sections 110 and the lintel 107. For simplicity, both the jamb 105 and the lintel 107 are referred to as the jamb 105. One of skill in the art will recognize that the embodiments may be applied to both the vertical jamb 105 and the horizontal lintel 107.
FIG. 2C is a top view drawing illustrating one alternate embodiment of a section 110 and a jamb 105. In the depicted embodiment, the door seal 148 is disposed on the jamb traverse face 115.
FIG. 3A is a top view drawing illustrating one embodiment of a section 110 and jamb 105 with an under-track door seal 200. The section 110 and jamb 105 may be the cross section 160 of the section door 100 of FIG. 1. The jamb angle 144 is positioned like the jamb angle 144 in FIG. 2A. In the depicted embodiment, the under-track door seal 200 is shown forming a seal between the jamb 105 and the section 110. The under-track door seal 200 may be installed by loosening the track fastener 146 and sliding the under-track door seal 200 between the jamb interior face 120 and the jamb angle 144. The track fastener 146 is then tightened to secure the under-track door seal 200 in place.
One of skill in the art will recognize that the under-track door seal 200 may form a seal between multiple sections 110 and the jamb 105. Alternatively, the under-track door seal 200 may form a seal between one or more sections 110 and the lintel 107. The under-track door seal 200 connects to the jamb interior face 120 along a longitudinal axis of the jamb interior face 120.
In addition to forming a seal between the sectional door 100 and the jamb 105, the under-track door seal 200 separates the jamb angle 144 from the jamb 105, forming a thermal break between the sectional door 100 and walls connected to the jamb 105.
FIG. 3B is a top view drawing illustrating one embodiment of a section 110 and jamb 105 with an under-track door seal 200. The section 110 and jamb 105 may be the cross section 160 of the section door 100 of FIG. 1. The jamb angle 144 is positioned like the jamb angle 144 in FIG. 2B. In the depicted embodiment, the track fastener 146 is loosened to allow a wall flange of the under-track door seal 200 to be slid between a track fastener head and the jamb angle 144. The track fastener 146 may be tightened to hold the under-track door seal 200 in place.
FIG. 4 is a perspective view drawing illustrating one embodiment of the under-track door seal 200. The under-track door seal 200 is depicted connected to the jamb interior face 120 along the latitudinal axis 155 of the jamb interior face 120. The under-track door seal 200 includes a jamb interface 210 and a flap 205. The flap 205 and the jamb interface 210 may be formed of an elastomer. In one embodiment, the jamb interface 210 and the flap 205 are extruded as a single piece.
The jamb interface 210 may be in physical communication with the jamb interior face 120 along a longitudinal axis 155 of the jamb interior face 120. The jamb interface 210 may be slid between the jamb angle 144 and the jamb interior face 120 after the track fastener 146 is loosened.
The jamb interface 210 may have a specified width 215 along a latitudinal axis 145. In one embodiment, the specified width is in the range of 9 to 14 centimeter (cm). In a certain embodiment, the specified width is in the range of 4 inches to 5.5 inches. In one embodiment, a roughness Ra of the surface of the jamb interface 210 that connects to the jamb interior face 120 is in the range 50,000 to 100,000 micro inches.
The flap 205 is disposed at an angle 202 to the jamb interface 210. In one embodiment, the angle 202 is in the range of 110° to 150°. The flap 205 may be flexible. As a result, the flap 205 may bend when the flap 205 contacts the section 110 and forms a seal, increasing the angle 202. By connecting to the jamb interior face 120, the under-track door seal 200 improves the seal between the jamb 105 and the section 110. In addition, the under-track door seal 200a is less susceptible to damage.
A plurality of fingers 225 are formed in the jamb interface 210. Each finger 225 may have a specified finger height 230. In addition, each finger 225 may be separated from adjacent fingers 225 by a specified spacing height 262. In one embodiment, the specified finger height 230 is in the range of 1 to 1.5 cm and the specified spacing height 262 is in the range of 1 to 1.5 cm. In a certain embodiment, the specified finger height 230 is 1.2446 cm and the specified spacing height 262 is 1.2954 cm.
The finger spacing 235 accommodates 3⁄8 inch diameter lag bolts that are typically used as track fasteners 146. In addition, the specified spacing height 262 and specified finger height 230 accommodate the vertical spacing of the track fasteners 146 in a typical track 140 installation.
A proximal edge 242 of the finger 225 may be in the range of 4 to 6.5 cm along the latitudinal axis 145 from an intersection 244 of the flap 205 and the jamb interface 210. A distal edge 244 of the finger 225 may be in the range of 4 to 6.5 cm along the latitudinal axis 145 from the proximal edge 242.
The specified width 215, specified finger height 230, specified spacing height 262, and distance from the proximal edge 242 to the intersection 244 are selected to be compatible with almost all sectional door 100 installations in the last 75 years. As a result, the under-track door seal 200 may be installed in easily and quickly with any make and model of sectional door 100.
In one embodiment, one or more of the fingers 225 are scored 240 at the proximal edge 242. The scoring 240 may be an indentation, a groove, or the like. The scoring 240 may be to a depth of 0.079375 cm. In one embodiment, when the finger 225 is bent at the score 240, the finger 225 may be separated from the jamb interface 210 to allow a track fastener 146 to fit within the fingers 225.
FIG. 5 is a top view drawing illustrating one embodiment of an under-track door seal 200a. The under-track door seal 200a is the under-track door seal 200a of FIG. 4. The flap 205 and the jamb interface 210 are shown.
FIG. 6 is a top view drawing illustrating one alternate embodiment of an under-track door seal 200e. The under-track door seal 200e is depicted with a jamb flange 260. The jamb flange 260 is disposed at the intersection 244 of the flap 205 and the jamb interface 210. The jamb flange 260 may be orthogonal to the latitudinal axis 145 and the longitudinal axis 155, and abut the jamb traverse face 115 of the jamb 105. The jamb flange 260 may be extruded as a single piece with the flap 205 and the jamb interface 210. In one embodiment, the jamb flange 260 extends the seal between the section 110 and the jamb 105.
FIG. 7 is a top view drawing illustrating one alternate embodiment of an under-track door seal 200f. The under-track door seal 200f is depicted with a wall flange 270. The wall flange 270 may be disposed at a distal edge 246 of the jamb interface 210. In one embodiment, the wall flange 270 is orthogonal to the latitudinal axis 145 and orthogonal to the longitudinal axis 155 of the jamb interior face 120. In addition, the wall flange 270 may be in physical communication with the lintel 270.
FIG. 8 is a schematic flow chart diagram illustrating one embodiment of a door seal method 500. The method 500 may perform the functions of the under-track door seal 200 of FIGS. 1-10. The method 500 starts and the track fastener 146 may be loosened 505. The under-track door seal 200 may be inserted 510 so that the fingers 225 of the under-track door seal 200 may be positioned on either side of the track fastener 146 so that the track fastener 146 is within the finger spacing 235. The jamb interface 210 is in physical communications with the jamb interior face 120 of the jamb 105 along the longitudinal axis 155 of the jamb interior face 120. The flap 205 seals between the section door 100 and the jamb 105. The track fastener 146 may be tightened 515 to secure the under-track door seal 200 in place relative to the jamb 105 and the method 500 ends.
Because the fingers 225 allow the track fastener 146 to be positioned within the finger spacing 235, the under-track door seal 200 may be quickly and accurately positioned relative to the jamb 105 by an installer. As a result, installation is more rapid and results in reduced seal leaks.
The embodiments may be practiced in other specific forms. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
