One or more embodiments set forth herein relate to a door assembly, and more particularly to a connection system for a door header and a door jamb of the door assembly.
Door assemblies typically include door jambs along the sides of the door opening, and a door mounted to at least one of the door jambs. The door assembly also includes a door header that extends between and connects the door jambs.
Typically, the door jambs are connected to the door header with fasteners positioned in clearance holes of the door jamb and/or door header. The alignment of the door header to the door jamb is typically finely adjusted by the installation technician to ensure proper operation of the door. This alignment adjustment can require a significant amount of time, and the clearance holes provided for adjustment can cause the fasteners to be load bearing. The load bearing on the fasteners could cause slippage in the header to jamb connection if the fastener loading is too high.
One or more embodiments includes a door assembly with at least one door, and a frame for receiving the door. The frame includes at least one jamb and a header. A connection system is provided that directs all or a portion of the weight of the header directly into the jamb while assisting in aligning the header and the jamb during installation. Load on the fasteners is reduced by the connection system along with the potential for slippage of the header after installation.
This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings.
The various advantages of the exemplary embodiments will become apparent to one skilled in the art by reading the following specification and appended claims, and by referencing the following drawings, in which:
For the purposes of clearly, concisely and exactly describing illustrative embodiments of the present disclosure, the manner, and process of making and using the same, and to enable the practice, making and use of the same, reference will now be made to certain exemplary embodiments, including those illustrated in the figures, and specific terminology will be used to describe the same. It shall nevertheless be understood that no limitation of the scope of the invention is thereby created and that the invention includes and protects such alterations, modifications, and further applications of the exemplary embodiments as would occur to one skilled in the art.
A door assembly 100 is disclosed herein in
In an embodiment, the door assembly 100 includes a door 102 having at least one panel 104 movable between an open position and a closed position. The door assembly 100 also includes a frame 106 for receiving the door 102. The frame 106 includes header 160 extending in a horizontal or first direction A along a top 108 of the door 102. The frame 106 includes jamb 120 extending in a vertical or second direction V transversely to the first direction A along a side 110 of the door 102.
The frame 106 includes connection system 200 for connecting the header 160 and the jamb 120. The connection system 200 includes a header mounting block 260 connected to the header 160 and a jamb mounting block 220 connected to the jamb 120. The jamb mounting block 220 and the header mounting block 260 are engaged to one another with a plurality of protrusions 222, 224, 226 that are received within corresponding ones of a plurality of receptacles 262, 264, 266. The engaged protrusions 222, 224, 226 and receptacles 262, 264, 266 of the jamb mounting block 220 and the header mounting block 260 align the header 160 and the jamb 120 with one another and support the header 160 on the jamb 120.
In an embodiment, connection system 200 is provided for connecting header 160 and jamb 120 of frame 106 for door 102. The connection system 200 includes jamb mounting block 220 configured to be engaged to an upper end 122 of the jamb 120, and header mounting block 260 configured to be engaged to an end 162 of the header 160. The connection system 200 includes a plurality of protrusions 222, 224, 226 that extend from at least one of the jamb mounting block 220 and the header mounting block 260, and a plurality of receptacles 262, 264, 266 that extend into at least one of the jamb mounting block 220 and the header mounting block 260. The plurality of protrusions 222, 224, 226 and the plurality of receptacles 262, 264, 266 are configured to engage one another to align the header 160 and the jamb 120 and support the header 160 on the jamb 120.
Referring to
Frame 106 includes vertically extending jambs 120 on each side 110 of door 102, and a header 160 along top 108 of door 102. Header 160 is oriented in a first or horizontal direction A, and jambs 120 are oriented in a second or vertical direction V that is transverse to horizontal direction A. In addition, a front-to-back direction though door 102 is indicated by a third direction B that is transverse to horizontal direction A and vertical direction V.
During installation of door assembly 100, it is necessary to construct frame 106 in the wall opening that is provided. As shown in
Connection system 200 includes jamb mounting block 220 and header mounting block 260. Jamb mounting block 220 includes protrusions 222, 224, 226 extending through jamb 120 toward header 160. Header mounting block 260 includes receptacles 262, 264, 266 that are configured to receive respective ones of the protrusions 222, 224, 226 to align header 160 with jamb 120. In an embodiment, protrusions 222, 224, 226 correspond in size and shape with the receptacles 262, 264, 266 to fit therein. Since protrusions 222, 224, 226 extend through jamb 120, the weight supported on protrusions 222, 224, 226 is vertically supported on jamb 120. The weight of header 160 is therefore vertically transferred to jamb 120 through protrusions 222, 224, 226.
Referring further to
Jamb 120 includes an inner sidewall 124 that faces door 102 and an opposite outer sidewall 126 spaced from inner sidewall 124.

Inner sidewall 124 includes a vertically extending channel 134 located mid-width on inner sidewall 124. Upper end 122 of jamb 120 also includes a cutout 136 in inner sidewall 124 that forms a pocket for receiving protrusion 222 so that protrusion 122 is above channel 134, and the upper side of protrusion 222 is recessed slightly below upper end 122 of jamb 120. Channel 134 extends through and intersects cutout 136. Jamb mounting block 220 and protrusion 222 span channel 134 and cutout 136. The plurality of protrusions 222, 224, 226 extend through respective ones of the cutout 136 and holes 138, 140 through inner sidewall 124. According, load on protrusions 222, 224, 226 is transmitted directly onto inner sidewall 124.
Jamb mounting block 220 includes a first arm 142 that is configured to extend across the jamb 120 along upper end 122. Protrusion 222 is located on first arm 142. Jamb mounting block 220 includes a second arm 144 that extends transversely to and downwardly from the first arm 142 that is configured to extend along the jamb 120. Protrusion 224 is located on an outer edge 146 of second arm 144. Protrusion 226 is located adjacent to bottom end 148 of second arm 144. Holes 138, 140 are spaced vertically from one another in the vertical direction V and offset from one another in the front-to-back direction B so as to receive protrusions 224, 226 therethrough. Cutout 136 is located above holes 138, 140.
A plurality of fasteners 150, 152, 154 secure jamb mounting block 220 to inner sidewall 124. In the illustrated embodiment, fastener 150 is secured to first arm 142 on the front part of inner sidewall 124, and fasteners 152, 154 are secured to first arm 142 and/or second arm 144 on the back part of inner sidewall 124 on the opposite sides of channel 134.
