Description

BACKGROUND

Partition systems are often employed to isolate portions of a building or room, by serving as a barrier to dust, noise, light, odors, and the like. In construction zones, partitions are useful for protecting a clean area from a work area, for example, protecting an area where furniture and rugs are temporarily stored from an area where wood floors are being refinished.

Workers at construction sites often use rudimentary techniques for installing partitions. Some simply nail, screw, or staple the curtain or partition material to the floor, ceiling, and abutting walls, resulting in damage to their surfaces. Others tape, or otherwise adhere, a curtain or plastic sheet to the walls and ceilings. The tape usually fails to stick, but if it does stick, as the tape is removed, paint can pull off with the tape, or adhesive is left behind.

U.S. Pat. Nos. 5,924,469 and 7,658,219, the contents of which are incorporated herein by reference, disclose partition mount systems that address these limitations. Such systems are compatible with a variety of commercially-available curtain or drape materials, for example plastic, cloth, and the like. The disclosed systems are “clean” systems designed to be installed and removed without damaging or otherwise marking the ceiling, floor or walls in the construction zone. Assembly is easy and fast and can be accomplished by a single individual.

In some situations, it is desired to have a defined entryway location for ingress into/egress from a partitioned area. In some situations, it is desired to have a defined entryway that is removably coupled to a neighboring curtain or door frame.

DETAILED DESCRIPTION OF EMBODIMENTS

Various example embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some example embodiments are shown. The present inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein.

It will be understood that when an element or layer is referred to as being “on,” “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numerals refer to like elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present inventive concepts.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element's or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. A first element may be said to be “transverse” to a second element if the first element has a direction of extension that is not parallel to the direction of extension of the second element.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting of the present inventive concepts. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Example embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized example embodiments (and intermediate structures). As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, example embodiments should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in such shapes.

FIG. 1A is a perspective view of an embodiment of a magnetic door 100, in accordance with aspects of inventive concepts herein. In some embodiments, such as the one shown in FIG. 1A, the magnetic doorway 100 comprises a first portion 110, a second portion 120, and a third portion 130. In some embodiments, such as the one shown in FIG. 1A, the first portion 110 and the second portion 120 can be removably coupled to each other such that an opening 5 exists between them (see FIG. 8). In the embodiment shown in FIG. 1A, the magnetic door 100 comprises one opening 5. In alternative embodiments, the magnetic door 100 may comprise more than one opening.

In the embodiment shown in FIG. 1A, the magnetic door 100 has a rectangular shape. In alternative embodiments, the magnetic entryway 100 comprise alternative shapes, including, but not limited to, a circle, square, triangle, or any such suitable polygon or any combinations thereof.

In the embodiment of FIG. 1A, the magnetic door 100 comprises a first seam 111 at an inner edge of the first portion 110 and a second seam 121 at an inner edge of the second portion 120. In some embodiments, each of the first and second seams 111, 121 comprises a plurality of elongated magnets. In some embodiments, the elongated magnets are cylindrical in shape, with a circular cross-section. In other embodiments, the elongated magnets comprise bars that have a rectangular or square cross-section. In various embodiments, the magnets comprise permanent magnets. In some embodiments, the magnets comprise a material type of one or more of ferromagnetic material, a metal, alloy or composite material that exhibits magnetic properties, or other suitable magnetic material.

FIG. 1B is a front view of an embodiment of an arrangement of magnets at the seams 111, 121 of a magnetic door 100, in accordance with aspects of inventive concepts herein. In some embodiments, the elongated magnets are positioned along the seams 111, 121 so that a first magnet 71 in the first seam 111 is positioned at a vertical position opposite a second magnet 72 of the second seam 121, as shown in FIG. 1B and FIG. 1C. In particular each first magnet 71 of the first seam 111 and corresponding second magnet 72 of the second seam 121 may be positioned so that their respective north N and south S poles are opposite, and therefore, they attract each other as shown. In this manner, the magnetic fields of the neighboring magnets may be naturally attractive to each other, biasing the magnetic door 100 to be naturally biased to be in a closed state. In some embodiments, the magnets may be secured into defined vertical positions, for example by horizontal seam stitching to fix their respective vertical positions, and thus ensure long-term attraction of the first and second seams 111, 121. In some embodiments, the magnets may be positioned in a sleeve portion of the seams 111, 121. In another embodiment, one of the seams of seams 111 and 121 can include magnets and the other seam of the seams 111 and 121 can include elements of magnetically attractive material, such as metal elements.

In the embodiment shown in FIG. 1B the second magnet 72 is oriented with a south pole above a north pole. In alternative embodiments, the second magnet 72 is oriented with a north pole above a south pole.

In some embodiments, the magnets 71 and 72 comprise discrete elements, rather than bars. In some embodiments, the discrete elements can comprise spherical elements, round elements, or discrete elements of other geometries. The individual magnets 71 and 72 can be positioned to be separate from each other in a vertical direction, and can be selected so that corresponding neighboring magnets on the opposite seam 111, 121 are attractive. In another embodiment, one of the seams 111, 121 can include magnets and the other seam 121, 111 can include elements of magnetically attractive material, such as metal elements.

In alternative embodiments, the magnets may be configured in a manner similar or identical to configurations described in PCT Publication No. WO 2017/117042.

In some embodiments, such as the one shown in FIG. 1B, the first seam 111 of the magnetic entryway 100 further comprises a third magnet 73. In the embodiment shown in FIG. 1B, the second seam 121 of the magnetic door 100 further comprises a fourth magnet 74. In some embodiments, the third 73 and fourth 74 magnets are constructed and arranged to magnetically couple.

In some embodiments, the magnitude of the magnetic force between the third magnet 73 and the fourth magnet 74 is greater than the magnitude of the magnetic force between the first magnet 71 and the second magnet 72. In some embodiments, the magnitude of the magnetic force between the third magnet 73 and the fourth magnet 74 is weaker than the magnitude of the magnetic force between the first magnet 71 and the second magnet 72. The magnets with the weaker force between them may be easier to separate, facilitating easier seam separation. The magnets with the stronger force between them may recouple more easily, facilitating easier seam recoupling.

In the embodiment shown in FIG. 1B, the first magnet 71 comprises a first length, the second magnet 72 comprises a second length, the third magnet 73 comprises a third length, and the fourth magnet 74 comprises a fourth length. In some embodiments, such as the embodiment in FIG. 1B, the magnitude of the first length is the same as the magnitude of the second length. In some embodiments, such as the embodiment in FIG. 1B, the magnitude of the third length is the same as the magnitude of the fourth length. In some embodiments, the first length and the second length are greater in magnitude than the third length and the fourth length.

In some embodiments, the magnet pairs comprising longer lengths are the magnet pairs with a weaker magnetic force between them. In some embodiments, the magnet pairs comprising longer lengths are the magnet pairs with a stronger magnetic force between them.

In the embodiment shown in FIG. 1B the third magnet 73 is oriented with a south pole above a north pole. In alternative embodiments, the third magnet 73 is oriented with a north pole above a south pole.

In the embodiment shown in FIG. 1B the fourth magnet 74 is oriented with a south pole above a north pole. In alternative embodiments, the fourth magnet 74 is oriented with a north pole above a south pole.

In the embodiment shown in FIG. 1B, the first magnet 71 and the second magnet 72 form a first pair. In the embodiments shown in FIG. 1B, the third magnet 73 and the fourth magnet 74 form a second pair.

In some embodiments, the first magnet 71 and the third magnet 73 are spaced apart in a substantially vertical direction, that is, by a vertical gap. In some embodiments, the first magnet 71 abuts the third magnet 73.

In some embodiments, the second magnet 72 and the fourth magnet 74 are spaced apart in a substantially vertical direction, that is, by a vertical gap. In some embodiments, the second magnet 72 abuts the fourth magnet 74.

Although FIG. 1B shows two pairs of magnets, the embodiment of FIG. 1A may include any number of magnet pairs and one or more of the magnet pairs may include the characteristics described in connection with FIG. 1B.

FIG. 1C is a front view of an embodiment of an arrangement of magnets at the seams 111, 121 of a magnetic door 100, in accordance with aspects of inventive concepts herein. In some embodiments, such as the one shown in FIG. 1C, different types of magnets 71/72, 73/74, 75/76 are used, with the magnitude of the force between the first set of magnets 71 and 72 being greater than the magnitude of the force between the second set of magnets 73, 74 and the magnitude of the force between the third set of magnets 75, 76. The magnitude of the force between the second set of magnets 73, 74 is greater than and the magnitude of the force between the third set of magnets 75, 76. In alternative embodiments, the arrangement of the magnet pairs differs. In some cases, the magnets with the greatest force between them are below those with a weaker force between them. In some embodiments, any of the patterns of magnet pairs repeats along the length of the magnetic door 100.

In some embodiments, the magnetic pairs may comprise different lengths from each other.

In some embodiments, the third magnet 73 and a fifth magnet 75 are spaced apart in a substantially vertical direction, that is, by a vertical gap. In some embodiments, the third magnet 73 abuts the fifth magnet 75.

In some embodiments, the fourth magnet 74 and a sixth magnet 76 are spaced apart in a substantially vertical direction, that is, by a vertical gap. In some embodiments, the fourth magnet 74 abuts the sixth magnet 76.

Although FIG. 1C shows three pairs of magnets, the embodiment of FIG. 1A may include any number of magnet pairs and one or more of the magnet pairs may include the characteristics described in connection with FIG. 1C.

In some embodiments, the first portion 110 comprises a first bottom seam 112. In some embodiments, the first portion 110 comprises a second bottom seam 113. In some embodiments, the second portion 120 comprises a first bottom seam 122. In some embodiments, the second portion 120 comprises a second bottom seam 123.

In some embodiments, magnets positioned at opposite seams 111, 121 have opposite polarities creating a magnetic force between the left seam and the right seam so at a resting position the magnetic force is strong enough to retain the seams 111, 121 so that they remain positioned next to each other. At the same time, the magnets can be selected to be of a weak enough strength so that their magnetic attraction force is sufficiently weak to allow an operator to break the attractive seam and readily walk through the seam without much constraint. In some embodiments the magnets are selected to be of a strength so that a simple elbow nudge would create a large enough force to break the magnetic force between the seams 111, 121.

In some embodiments, the magnetic door automatically closes after a user walks through. As a result of the positioning of the magnets, and, as a result of the proximity of the magnets when the magnetic door 100 naturally drapes back into position in the opening 5 as a result of gravity and as a result of the magnetic attraction, the left and right seam portions 111, 112 re-locate with respect to each other and automatically close. Registration of the left and right seam portions together, that is, the reconnection of the first seam 111 and the second seam 112 after a user walks through the opening, can be further ensured by a number of factors including: relative placement of the magnets in the left and right seam portions 111, 121, placement of weights at a bottom portion of the magnetic door 100 at its lower end, the tautness of the mounting of the magnetic door 100, the material of the magnetic door 100, the weight of the magnetic door 100, and other factors, and combinations of these factors. In this manner, the magnetic door 100 operates to re-couple, automatically preparing the magnetic door 100 for the next operator to pass through.

In some embodiments, a lower region of the first portion 110 comprises a weight that is greater than an upper region of the first portion 110 to ensure or improve registration of the first 111 and second seams 121 together by applying longitudinal tension to the body of the magnetic door 100. In some embodiments, a lower region of the second portion 120 comprises a weight that is greater than an upper region of the second portion 120 to ensure or improve registration of the first 111 and second seams 121 by applying longitudinal tension to the body of the magnetic door 100.

In some embodiments, an upper region of the first portion 110 comprises a weight that is greater than a lower region of the first portion 110 to ensure or improve registration of the first 111 and second seams 121 together by applying longitudinal tension to the body of the magnetic door 100. In some embodiments, an upper region of the second portion 120 comprises a weight that is greater than a lower region of the second portion 120 to ensure or improve registration of the first 111 and second seams 121 together by applying longitudinal tension to the body of the magnetic door 100.

In some embodiments, such as the one shown in FIG. 1A, the magnetic door 100 comprises a third portion 130. In the embodiments shown in FIG. 1A, the third portion 130 extends horizontally across the top of the magnetic door 100. That is, the third portion 130 extends along upper portions of the first portion 110 and the second portion 120. In some embodiments, a seam extends along the upper portions of the first portion 110 and the second portion 120. In some embodiments, no seam extends along the upper portions of the first portion 110 and the second portion 120. The third portion 130 provides space in the magnetic door 100 between the top of the opening 5 and a top of the magnetic door 100. In some embodiments, the third portion 130 comprises a sleeve. In some embodiments, the sleeve comprises one or more characteristics identical or similar to those described in connection with WO 2017/117042, which is incorporated by reference in its entirety herein. In some embodiments, the sleeve comprises one or more characteristics identical or similar to those described in connection with WO 2020/118277, which is incorporated by reference in its entirety herein.

In some embodiments, such as the one shown in FIG. 1A, the magnetic door 100 comprises at least one window 150. In alternative embodiments, the magnetic door 100 does not comprise any windows. In alternative embodiments, the magnetic door 100 comprises more than one window 150.

In the embodiment shown in FIG. 1A, the second portion 120 comprises a window 150. In alternative embodiments, the at least one window 150 is on the first portion 110. The position of the window 150 is not limited to the position illustrated in FIG. 1A.
