Description

Mounting assembly for door or window and door or window assembly using same

Technical Field

The present invention relates generally to a door and window system, and more particularly to a mounting assembly for a door or window and a door or window assembly using the same.

Background

In a conventional door system using a conventional hinge, a large-sized gap exists between a hinge portion of the door and a door frame to which the door is attached when the door is in an open position. When the fingers are caught by the gap and the door is moved into the closed position, injury to the fingers may result. Therefore, it is necessary to avoid the occurrence of similar injuries by using a mounting assembly (mounting assembly) for a door or window and a door or window assembly (door window assembly).

Disclosure of Invention

It is therefore a first aspect of the present invention to provide a mounting assembly for a door or window. The mounting assembly includes a jamb configured to define a housing to conceal the hinged portion of the door or window. A support structure is coupled to the jamb and provides a surface for providing attachment in the housing.

A second feature of the present invention is to provide a door or window assembly including a jamb disposed to define a housing for concealing a hinged portion of a door or window. A support structure is coupled to the jamb and provides a surface for providing attachment in the housing. A hinge is attached to the support structure and a leaf of a door or window is attached to the hinge.

Other features and advantages of the present invention will be apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

Detailed Description

The detailed description set forth below in connection with the appended drawings is intended as a description of the presently preferred embodiments of the invention and is not intended to represent the best modes contemplated for carrying out the invention. It is to be understood that the same or equivalent functions may be accomplished by different embodiments that are also intended to be encompassed within the scope of the invention.

Referring now to fig. 1A and 1B, a mounting assembly 10 is shown with a door or window 12 mounted to the mounting assembly 10. The door or window 12 is shown in a closed position in FIG. 1A, and the door or window 12 is shown in an open position in FIG. 1B. In the illustrated embodiment, a stop 14 disposed at the distal end of the door or window 12 is used to limit the rotation of the door or window 12.

The mounting assembly 10 includes a jamb 16 arranged to define a housing 18, thereby concealing, accommodating and/or covering the hinged portion of the door or window 12. A support structure 20 is coupled to the jamb 16 and provides a surface for providing attachment in the housing 18.

The jamb 16 of the present embodiment comprises a first wall 22 and a second wall 24, the second wall 24 being adjacent to the first wall 22, the first wall 22 having a first projection 26 and the second wall 24 having a second projection 28. The first and

second projections

26, 28 are utilized to reduce the gap that exists between the mounting assembly 10 and the door or window 12 when the door or window 12 is in either the open or closed position and also when the door or window 12 is rotated between the open and closed positions.

The support structure 20 of the present embodiment includes a first support assembly 30 and a second support assembly 32. First support assembly 30 extends from first wall 22 of jamb 16 in a direction parallel to the plane of second wall 24 of jamb 16, and second support assembly 32 extends from first support assembly 30 in a direction parallel to the plane of first wall 22 of jamb 16.

In the present embodiment, the hinge 34 is attached to the second support assembly 32 of the support structure 20. In the illustrated embodiment, the first leaf 36 of the hinge 34 is attached to the second support assembly 32 in a direction parallel to the plane of the first wall 22. Thus, when the door or window 12 is in the closed position, the hinge 34 is in the open position, and when the door or window 12 is in the open position, the hinge 34 is in the closed position. This is advantageous in order to increase the durability and longevity of hinge 34, because door or window 12 in the open position is freely suspended and unsupported by any structure, where hinge 34 is most stressed, while door or window 12 in the closed position may have multiple support sources, such as bolts and latches for door locks or seals on door frames, by which it helps to spread forces away from hinge 34. Thus, it is advantageous to have the hinge 34 in the closed position when the door or window 12 is in the open position, and to have the hinge 34 in the open position when the door or window 12 is in the closed position.

The mounting assembly 10 may be provided as a stand-alone door frame. Alternatively, the mounting assembly 10 may be mounted to an existing door frame and become an add-on to the door frame.

Referring now to fig. 2A-2C, a door or window assembly 50 is shown. The door or window assembly 50 is shown in a first position in FIG. 2A, the door or window assembly 50 is shown in an intermediate position in FIG. 2B, and the door or window assembly 50 is shown in a second position in FIG. 2C.

The door or window assembly 50 includes a jamb 52 positioned to define a housing 54 to conceal, contain and/or cover the hinged portion of the door or window 56. A support structure 58 is coupled to the jamb 52 and provides a surface for providing attachment in the housing 54. A hinge 60 is attached to the support structure 58 and a leaf 62 of the door or window 56 is attached to the hinge 60.

The jamb 52 of the present embodiment comprises a first wall 64 and a second wall 66, the second wall 66 being adjacent the first wall 64, and the first wall 64 having a first projection 68 and the second wall 66 having a second projection 70.

Support structure 58 of the present embodiment includes a first support assembly 72 extending from first wall 64 of jamb 52 in a direction parallel to the plane of second wall 66 of jamb 52, and a second support assembly 74 extending from first support assembly 72 in a direction parallel to the plane of first wall 64 of jamb 52.

In this embodiment, the first leaf 76 of the hinge 60 is attached to the second support member 74 in a direction parallel to the plane of the first wall 64. In the embodiment shown, a second leaf (not shown) of the hinge 60 is attached to an edge 78 of the leaf 62 of the door or window 56, and a knuckle 80 of the hinge 60 abuts the edge 78 of the leaf 62 of the door or window 56.

In this embodiment, the leaf 62 of the door or window 56 includes a first extended surface 82 and a second extended surface 84 opposite the first extended surface 82, wherein both the first extended surface 82 and the second extended surface 84 extend beyond the edge 78 of the leaf 62 of the door or window 56.

As can be seen in fig. 2A, when the leaf 62 of the door or window 56 is in the first position, the first extension surface 82 in this embodiment is received in a first space between a distal surface 86 of the first projection 68 and an inner surface 88 of the second support member 74 and the second extension surface 84 is aligned with the second projection 70.

Similarly, as can be seen in fig. 2C, when the leaf 62 of the door or window 56 is in the second position, the second extension surface 84 is received in the second space between the distal surface 90 of the second projection 70 and the outer surface 92 of the first bearing assembly 72 and the first extension surface 82 is aligned with the first projection 68.

The first and second extension surfaces 82, 84 may be part of or an addition to the leaf 62 of the door or window 56. In the embodiment shown, the second extension surface 84 is removably attached to the leaf 62 of the door or window 56, which may be using a clamping system as shown or other conventional fastening means. By providing at least one extended surface that facilitates external disassembly, the door or window assembly 50 can be easily installed and future maintenance work of the door or window assembly 50 can be facilitated. To increase the aesthetic appeal of the door or window assembly 50, the first and second extension surfaces 82, 84 are preferably secured to the leaf 62 of the door or window 56 without any visible screws, and the first and second extension surfaces 82, 84 may be of the same or similar material and/or color as the jamb 52 and leaf 62 of the door or window 56 to increase visual uniformity.

The clearance between the jamb 52 and the leaf 62 of the door or window 56 is reduced by providing first and

second projections

68, 70 on the jamb 52 and first and second extension surfaces 82, 84 on the leaf 62 of the door or window 56. As can be seen in fig. 2A and 2C, the door or window assembly 50 has only minimal clearance between the first and

second protrusions

68, 70 of the jamb 52 and the first and second extension surfaces 82, 84 of the leaf 62 of the door or window 56 when in the first and second positions. During rotation as shown in fig. 2B, the first and second extension surfaces 82, 84 of the leaf 62 move in a circular manner within the jamb 52 in concert with rotation of the leaf 62 of the door or window 56. During rotation, a minimum clearance, less than the width of the fingers, emerges from both sides of the leaf 62 of the door or window 56. Thus, with the door or window assembly 50, fingers are prevented from being crushed by rotating the door or window.

Furthermore, as can be seen in FIGS. 2A-2C, the hinge 60 of the door or window assembly 50 and any screws (not shown) used on the hinge 60 can be concealed under any direction of the leaf 62 of the window 56, thereby increasing the overall aesthetic appeal of the door or window assembly 50. Under the influence of the door or window assembly 50, there will not be any visible unsightly hinges or pivot points on either or both of the interior and exterior sides of the door or window assembly 50. Thus, the hinge 60 may be any color or material as desired without affecting the appearance of the door or window assembly 50. Advantageously, any wiring provided in the door or window assembly 50 or additional components such as sensors and alarms may be concealed in the same manner.

Referring now to fig. 3A-3C, another embodiment of a door or window assembly 100 is shown. The door or window assembly 100 is shown in a first position in fig. 3A, the door or window assembly 100 is shown in an intermediate position in fig. 3B, and the door or window assembly 100 is shown in a second position in fig. 3C.

The door or window assembly 100 includes a jamb 102 configured to define a housing 104, thereby concealing, accommodating and/or covering the hinged portion of the door or window 106. A support structure 108 is coupled to the jamb 102 and provides a surface for providing attachment in the housing 104. A hinge 110 is attached to the support structure 108 and a leaf 112 of the door or window 106 is attached to the hinge 110.

The jamb 102 of the present embodiment comprises a first wall 114 and a second wall 116, the second wall 116 is adjacent to the first wall 114, and the first wall 114 has a first protrusion 118 and the second wall 116 has a second protrusion 120.

The support structure 108 of the present embodiment includes a first support assembly 122 and a second support assembly 124. A first support assembly 122 extends from the first wall 114 of the jamb 102 in a direction parallel to the plane of the second wall 116 of the jamb 102 and a second support assembly 124 extends from the first support assembly 122 in a direction parallel to the plane of the first wall 114 of the jamb 102.

In this embodiment, the first leaf 126 of the hinge 110 is attached to the second support member 124 in a direction parallel to the plane of the first wall 114. In the embodiment shown, the second leaf 128 of the hinge 110 is attached to the edge 130 of the leaf 112 of the door or window 106, and the knuckle 132 of the hinge 110 abuts the edge 130 of the leaf 112 of the door or window 106.

In this embodiment, the leaf 112 of the door or window 106 includes a first extended surface 134 and a second extended surface 136 opposite the first extended surface 134, wherein both the first extended surface 134 and the second extended surface 136 extend beyond the edge 130 of the leaf 112 of the door or window 106.

As can be seen in fig. 3A, when the leaf 112 of the door or window 106 is in the first position, the first extension surface 134 in this embodiment is received in the first space between the distal surface 138 of the first protrusion 118 and the inner surface 140 of the second support member 124 and the second extension surface 136 is aligned with the second protrusion 120.

Similarly, as can be seen in fig. 3C, when the leaf 112 of the door or window 106 is in the second position, the second extension surface 136 is received in the second space between the distal surface 142 of the second protrusion 120 and the outer surface 144 of the first bearing assembly 122 and the first extension surface 134 is aligned with the first protrusion 118.

The present embodiment is different from the previous embodiments in that the first extension surface 134 and the second extension surface 136 have curved surfaces corresponding to their respective rotation circumferences. As can be seen in fig. 3, the curved surface is further advantageous to reduce the gap between the leaf 112 of the door or window 106 and the jamb 102 when the leaf 112 of the door or window 106 is rotated between the first position and the second position. Although the first extending surface 134 and the second extending surface 136 are illustrated as curved surfaces in the embodiment, it is understood by those skilled in the art that the present invention is not limited to the curved first and second extending surfaces. In an alternative embodiment, at least one of the first and second extending surfaces has a curved surface corresponding to a corresponding circumference of rotation.

As can be seen in fig. 3A to 3C, the distance D1 between the inner distal corner 146 of the first protrusion 118 and the rotational axis 148 of the hinge 110 is greater than the rotational radius R1 of the outer distal corner 150 of the first extending surface 134 of the leaf 112 of the door or window 106 about the rotational axis 148 of the hinge 110, and the distance D2 between the inner distal corner 152 of the second protrusion 120 and the rotational axis 148 of the hinge 110 is greater than the rotational radius R2 of the outer distal corner 154 of the second extending surface 136 of the leaf 112 of the door or window 106 about the rotational axis 148 of the hinge 110. In one embodiment, the distance D1 between the inner distal corner 146 of the first tab 118 and the rotational axis 148 of the hinge 110 can be less than 10 millimeters (mm) greater than the radius of rotation R1 of the outer distal corner 150 of the first extended surface 134 of the leaf 112 of the door or window 106 about the rotational axis 148 of the hinge 110. In the same or a different embodiment, the distance D2 between the inner distal corner 152 of the second protrusion 120 and the rotational axis 148 of the hinge 110 can be less than 10 millimeters greater than the radius of rotation R2 of the outer distal corner 154 of the second extending surface 136 of the leaf 112 of the door or window 106 about the rotational axis 148 of the hinge 110.

Referring now to fig. 4A-4C, another embodiment of a door or window assembly 100 is shown. The door or window assembly 100 is shown in a first position in fig. 4A, the door or window assembly 100 is shown in an intermediate position in fig. 4B, and the door or window assembly 100 is shown in a second position in fig. 4C.

The embodiment shown in fig. 4A-4C differs from the previous embodiment in the positioning of the hinge 110 relative to the second support assembly 124. Specifically, the first leaf 126 of the hinge 110 is attached to the second support assembly 124 in a direction parallel to the plane of the second wall 116.

Another difference is that neither of the first and second

extended surfaces

134, 136 of the leaf 112 of the door or window 106 in this embodiment is curved.

In the illustrated embodiment, the planar distance D3 between the distal surface 138 of the first tab 118 and the inner surface 140 of the second support member 124 is greater than the thickness T1 of the first extended surface 134 of the leaf 112 of the door or window 106. Further, in the illustrated embodiment, the planar distance D4 between the distal surface 142 of the second projection 120 and the outer surface 144 of the first bearing assembly 122 is at least the thickness T2 of the second extended surface 136 of the leaf 112 of the door or window 106. In an embodiment, the planar distance D3 between the distal surface 138 of the first tab 118 and the inner surface 140 of the second support member 124 can be less than 10 millimeters greater than the thickness T1 of the first extended surface 134 of the leaf 112 of the door or window 106. In the same or a different embodiment, the planar distance D4 between the distal surface 142 of the second projection 120 and the outer surface 144 of the first bearing assembly 122 can be less than 10 millimeters greater than the thickness T2 of the second extending surface 136 of the leaf 112 of the door or window 106.

Referring now to fig. 5A-5C, yet another embodiment of a door or window assembly 100 is shown. The door or window assembly 100 is shown in a first position in fig. 5A, the door or window assembly 100 is shown in an intermediate position in fig. 5B, and the door or window assembly 100 is shown in a second position in fig. 5C.

The present embodiment shown in fig. 5A-5C differs from the previous embodiments in the positioning of the first wall 114 relative to the second wall 116.

Another difference, unlike earlier embodiments, is that the second extension surface is removable, in this embodiment the first extension surface 134 is removably attached to the leaf 112 of the door or window 106.

Although shown in this embodiment as having a (1) removable extension surface, it will be understood by those skilled in the art that the present invention is not limited to one of the first and second extension surfaces (1) being a leaf that is removably attached to a door or window. In an alternative embodiment, both the first and second extension surfaces are or are non-removably attached to the leaf of the door or window. Advantageously, by providing at least one extension surface that is externally detachable, the door or window assembly 100 is easy to install and future maintenance work of the door or window assembly 100 is also easy to perform.

In the illustrated embodiment, the rotational axis 148 of the hinge 110 is located at or as close as possible to the center plane 156 of the leaf 112 of the door or window 106. Advantageously, when the hinge 110 is secured with the rotational axis 148 of the hinge 110 at or as close as possible to the center plane 156 of the leaf 112 of the door or window 106, the stress on the hinge 110 is reduced and the radius of rotation of the door or window 106 is minimized.

Referring now to fig. 6-9, in addition to the single panel pivoting door or window shown in fig. 1A and 1B, the mounting assembly 10 may be used to mount various other types of doors or windows and some examples of which are shown in fig. 6-9. More specifically, fig. 6 shows a two-panel, folding door or window 200 attached to mounting assembly 10, fig. 7 shows a multi-panel, folding door or window 202 attached to mounting assembly 10, fig. 8 shows a two-panel, sliding, rotating door or window 204 attached to mounting assembly 10, and fig. 9 shows a three (3) panel, sliding, folding door or window 206 attached to mounting assembly 10.

Referring now to fig. 10A and 10B, an illustration will be provided of one application of the mounting assembly 10. In the illustrated embodiment, the mounting assembly 10 is used in a public restroom 250 having a double frame unit 252. A door 254 is attached to the mounting assembly 10 and is movable between a first position, as shown in fig. 10A, in which the door 254 is for preventing access to the entire restroom 250, and a second position, as shown in fig. 10B, in which the door 254 is an area 256 for preventing access to the restroom 250. When the door 254 is in the first position, privacy of both the toilet area and the washing area of the restroom 250 is provided by the door 254. When the door 254 is in the second position, privacy of the toilet area of the public lavatory 250 may be provided by the door 254, allowing other people to access the wash area of the public lavatory 250. The flexibility provided by the utilization of the mounting assembly 10 allows for the use of a single door 254 in both (2) door openings without the need for a second divider door to be installed, thus achieving space and cost savings.

Advantageously, the hinge 34 of the mounting assembly 10 is completely hidden from the user of the restroom 250 regardless of the position of the door 254 in the first and second positions, thereby presenting a neat appearance and improving the overall appearance of the restroom 250.

It will be apparent from the foregoing discussion that the mounting assembly and door or window assembly provided by the present invention reduces the risk of finger injury when rotating a door or window. Advantageously, the present invention also provides a door or window assembly with improved aesthetics and a more durable hinge system.

Although the present invention has been described with reference to specific preferred embodiments, it will be understood by those skilled in the art that various changes, modifications, variations, substitutions and equivalents may be made without departing from the spirit and scope of the invention as defined by the appended claims.

Furthermore, unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense, i.e., in an inclusive and non-limiting sense.
