The field of this disclosure relates to door mounting systems and, more particularly, to such systems for mounting sliding doors on a wall adjacent to the door opening.
Door hanging systems include hinged doors and sliding doors. Hinged doors are hung from the side; they open and close by pivoting radially on the hinges. The door slab of a hinged door is sized to the door opening and fits in the door opening so snugly that, when closed, there is minimal clearance left between the perimeter of the door slab and the perimeter of the door opening. Sliding doors, by contrast, are supported from the top or the bottom of the door and slide linearly along a weight-bearing track or rail. A second track or rail, typically non-weight-bearing, may engage the other of the top or bottom of the door to prevent the door from swinging or tipping into the room or banging against the wall. Tracks for a sliding door may be installed within the door opening, for example, of a pocket-style door that receives the door slab into a pocket formed in the wall adjacent the door opening. Alternatively, in a barn-style sliding door, the top rail is installed outside the door opening, for example on a wall surface or trim surface above the door opening. The barn door opens by sliding along the wall, parallel to and outside the wall. In a barn-style door, the door slab is made larger than the door opening so that, when closed, the door slab of a barn-style door overlaps the wall by a few inches. Overlap is preferred for obscuring the door opening from sound or light traveling through the opening and, in aftermarket installations, for obscuring door frame trim leftover from a hinged door.
Sliding barn doors are appealing for a variety of reasons. Barn doors do not sweep as far into the room when opening as a hinged door. Barn doors are also preferable to pocket doors in that they do not require construction of a pocket within the wall. One downside to barn doors is that a renovator typically cannot reuse the door slab of a previous hinged door when upgrading to a barn door because the hinged door slab is too small; thus an entire new door must be purchased. The present inventors have recognized a need for a barn-style sliding door that can extend a door slab previously sized as a hinged door to a size suitable for use as a barn door and for a barn-style sliding door that is easy to install and attractive.
The present disclosure provides a sliding door for covering a door opening, comprising a door slab having a front face, a rear face opposite the front face, and spaced-apart top and bottom sides extending between the front and rear faces, the door slab having a slab height between the top and bottom sides and a width; a top extension member attached to the door slab adjacent the top side thereof, the top extension member having a first flange aligned with the front face of the door slab and extending along the width of the door slab, and an attachment member connected to the first flange and extending transversely therefrom, the attachment member being secured to the top of the door slab; and a bottom extension member attached to the door slab adjacent the bottom side thereof, the bottom extension member aligned with the front face of the door slab and extending along its width, the top and bottom extension members protruding beyond the respective top and bottom sides of the door slab to result in a door height of the door that is greater than the slab height.
The present disclosure further provides a method for installing a sliding barn door, comprising providing a rectangular door slab having a front face, a rear face opposite the front face, and spaced-apart top and bottom sides extending between the front and rear faces, the door slab having a slab height between the top and bottom sides and a width; providing a top extension having a first flange and a first wall-side flange connected to and spaced apart from and substantially aligned with the first flange, the first flange having a width approximately equal to the width of the door slab; providing a bottom extension having a second flange having substantially the same dimensions as the first flange; positioning the top extension at the top side of the door slab so that the first flange is aligned with the front face of the door slab to result in a door height of the door that is greater than the slab height; securing the top extension to the door slab; positioning the bottom extension at the bottom side of the door slab so that the second flange is aligned with the first flange and is adjacent to the front face of the door slab to further increase the door height of the door; and securing the bottom extension to the door slab.
Additional aspects and advantages will be apparent from the following detailed description of preferred embodiments, which proceeds with reference to the accompanying drawings.
This section describes particular embodiments and their detailed construction and operation. The embodiments described herein are set forth by way of illustration only and not limitation. Throughout the specification, reference to “one embodiment,” “an embodiment,” or “some embodiments” are not necessarily referring to the same embodiment. The described features, structures, characteristics, and methods of operation may be practiced in isolation or combined in any suitable manner, and can be practiced without one or more of the specific details or with other methods, components, materials, or the like. In other instances, well-known structures, materials, or methods of operation are not shown or not described in detail to avoid obscuring more pertinent aspects of the embodiments.
As shown in
With reference to
The H-shaped profile of the top extension also includes upper flange portions 141, 142 that extend upward, adding to the flexural rigidity of top extension 40 and providing structural support for including one or more hangers 150 that reach to top rail 60. Upper flange portion 141 and lower flange portion 101 together comprise first flange 90. A plurality of hangers 150 of the top extension carry low-friction contact members, preferably wheels 63, along top guide rail 60 installed above door opening 23. Hangers 150 may be integrally formed in top extension 40 or fixed to top bar 94 in the factory. Preferably, each hanger 150 includes holes 152 or pre-formed slots for the installer to attach hanger 150 to top bar 94. The top extension 40, including hangers, has a height that, when combined with bottom extension 50 and door slab 12, extends height 13 of door 10 beyond height 20 of door opening 23 to span approximately from floor 26 to top rail 60. Wheels 63 rest on top rail 60 to support the weight of door 10 and to enable a smooth translation of the door between open and closed positions. In some embodiments a groove 161 is formed in wheel 63 to engage top rail 60, or vice versa, to prevent wheels 63 from slipping off top rail 60. Pre-formed holes or slots are preferred in all pieces of mounting hardware that must be connected by the end user to enable the end user rapidly to assemble the mounting system in such a way that the weight-bearing point of contact (such as the point where wheel 63 contacts top rail 60) aligns vertically with the center of gravity of door 10 to enable door 10 to hang vertically rather than at an angle.
A person of skill in the art will appreciate that weight-bearing support members may be included in the bottom extension 50 without departing from the principles disclosed herein. Weight-bearing struts or hangers along with contact members may be attached to the bottom of the door, and the top extension 40 may include no hangers, or possibly non-weight-bearing or reduced-weight-bearing hangers, along with one or more contact members that engage the top rail or a guide post, to keep the door balanced vertically.
With reference to
The H-shaped profile of the bottom extension 50 also includes upper flange portions 240, 242 that extend downward, adding to the flexural rigidity of the bottom extension and providing a contact member (track 70) that engages a floor guide 67. Contact member 70 is formed integrally with bottom bar 180, and the floor guide in this embodiment comprises a post 67 mounted on the floor 26. A skilled person will appreciate that the locations of the track and the post may be reversed so that the post is included in the bottom extension 50 of the door and the track is mounted on the floor 26 or, alternatively, on the wall near the floor, without departing from the principles of this disclosure. In such embodiments (not shown), the term “floor guide” is not limited to tracks, posts, or rails mounted on the floor but may signify a track or a post or other guide mounted on the wall near the floor. In one embodiment, not shown, the bottom extension further includes holes or pre-formed slots for attaching one or more struts or hangers to the bottom extension. Struts or hangers of the bottom extension 50 may include wheels, or other low-friction couplers, which contact a floor guide when the door is installed. Lower flange portion 202 and upper flange portion 242 together comprise the second flange 92.
In some embodiments of door 10, door slab 12, sized as a hinged door, is extended at least one inch beyond height 20 of door opening 23 by attaching top extension 40 or bottom extension 50 or both in combination. In other embodiments, the height of the sliding door is extended by at least two inches, and in other, by at least three inches beyond the height 20 of the door opening 23. In such embodiments, the height of sliding door 10 may be measured from the bottom of door 10, at a point nearest the floor, to a contact member of the top extension (where the contact member is designed to contact the top rail or guide post) rather than from the bottom of bottom bar 180 to the top of top bar 94. In yet other embodiments, a kit for converting a hinged door into a sliding barn door includes a top extension and a bottom extension having a combined height that extends the height of the door slab of a hinged door by at least one inch, or by at least two inches, or by at least approximately three inches. In another embodiment, not shown, the door slab 12 is extended using only one of a top extension or a bottom extension.
The embodiment shown further includes an end cap 250 on one or more ends of bottom extension 50 or top extension 40. This improves the aesthetic appeal of the extension. End cap 250 may also serve as a stop, for instance on the bottom extension when it contacts the floor guide, such as post 67, to prevent the door from progressing further in one direction along the slide track. Other preferred embodiments, not shown, include a soft close mechanism to prevent the door from stopping its slide abruptly or banging against an end of its slide path. The end of the slide path may be determined at the top extension, the top rail, the bottom extension, or the floor guide. The soft close mechanism may be installed on any one of those or another suitable location, and a corresponding soft-close activator may be installed in any appropriate place to activate the soft close mechanism at the end of the sliding door's slide path.
The embodiment of
It will be obvious to those having skill in the art that many changes may be made to the details of the above-described embodiments without departing from the underlying principles of the invention. The scope of the present invention should, therefore, be determined only by the claims.
