Embodiments of the pole mount of the present patent application may be used in connection with the technology of any of the above patents or patent applications.
Partition mounting systems are employed to isolate portions of a building or room, by serving as a barrier to dust, noise, light, odors, and the like.
In commercial construction applications, for example in parking lots and at airports, it is desired that pole mounts for partition systems be held in place securely, in adverse conditions. Partition mounting systems in commercial construction, specifically, used outside, must be able to withstand adverse weather conditions, for example, wind.
Embodiments of the present inventive concepts are directed to a pole mount and methods of installation and application.
In one aspect, embodiments of the present inventive concepts include a pole mount including a telescoping, length-adjustable pole having a head end and a foot end. The pole mount further includes a coarse length-adjustment mechanism and a fine length-adjustment mechanism.

In some embodiments, the head comprises: a first portion, a portion of the first portion extending into an interior of the pole; and a second portion that extends transverse to the first portion.
In some embodiments, the pole mount further comprises: a foot coupled to an end of the threaded rod; and a pivot between the foot and threaded rod so that the foot and threaded rod pivot relative to each other.
In some embodiments, the quick release mechanism further comprises a pedal that engages and disengages the female threaded portion.
In some embodiments, the pole mount further comprises a compression meter indicating when a maximum longitudinal force is exceeded.

The foregoing and other objects, features and advantages of embodiments of the present inventive concepts will be apparent from the more particular description of preferred embodiments, as illustrated in the accompanying drawings in which like reference characters refer to the same elements throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the preferred 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.
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 shapes that result, for example, from manufacturing. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of the present inventive concepts.
In some embodiments, a pole mount 10 comprises a telescoping, length-adjustable pole 20, 30, 40. In some embodiments, the pole is adapted for use in adverse conditions, and therefore is constructed and arranged to withstand a longitudinally applied compressive force. In some embodiments, the pole mount can withstand 185 pounds of longitudinally compressive force. In some embodiments, the pole mount can withstand 250 pounds of longitudinally compressive force. In some embodiments, the pole mount can withstand a longitudinally compressive force greater than 250 pounds. In this manner, the pole system is suitable for use in connection with commercial construction applications. For example, the pole mount 10 may be securely mounted between, for example, a fixed concrete ceiling and a fixed concrete floor and positioned in place with outwardly applied longitudinal force operable on a ceiling and floor of a room. In some embodiments, for example as shown in the illustrative diagram of
The pole mount 10 is illustrated as including three telescoping pole segments 20, 30 and 40; however, the present inventive concepts are not limited thereto. For example, in various embodiments, the pole mount can include a single pole segment, two pole segments, or more than three pole segments. A cap 14 is positioned at an end of the innermost pole segment 20. The innermost pole segment 20 moves relative to the intermediate pole segment 30 in a telescoping arrangement and is locked into a position using a locking mechanism 50. The locking mechanism 50 is positioned at an end of the intermediate pole segment 30. In some embodiments, the locking mechanism 50 includes spring-loaded pins and levers 52. The innermost pole segment 20 includes a plurality of indexed holes 26, as illustrated in
The intermediate pole segment 30 moves relative to the outermost pole segment 40 in a telescoping arrangement and is locked into a position using a locking mechanism 60. The locking mechanism 60 is positioned at an end of the outermost pole segment 40. The locking mechanism 60 includes spring-loaded pins and levers 62. The innermost pole includes indexed holes 36, as illustrated in
In some embodiments, the locking mechanisms 50 and 60 including the corresponding levers and spring-loaded pins 52 are robust in form and can withstand the relatively large amount of compressive longitudinal pressure, and any lateral forces, exerted by or on the pole mount 10.
In some embodiments, one or more of the telescoping poles segments 20 and 30 each include at least one flat longitudinally oriented surface, namely, flat surfaces 22, 24 and 32. In some embodiments the innermost pole segment 20 is primarily square in cross-section and the intermediate pole segment 30 is primarily circular in cross-section with two flat outer surfaces. In some embodiments, the telescoping pole 20 may include four flat surfaces. In some embodiments, the telescoping pole 30 may include two flat surfaces on two rounded surfaces. The outermost telescoping pole segment 40 is illustrated as having round surfaces; however, the present inventive concepts are not limited thereto. The flat outer surfaces on the pole segments mate with flat inner surfaces of the locking mechanisms. This prevents the pole segments 20, 30, 40 from twisting relative to each other, thereby strengthening the resulting system, and ensuring engagement between the levers and spring-loaded pins 52, 62 and the corresponding indexed holes 26, 36.
In some embodiments, a head 200 extends from the head end of the innermost pole segment 20 and travels in a longitudinal direction along the longitudinal axis of the pole. The head 200 includes a rod 12, the rod in turn including a first end which extends into an interior of the pole and a second end having a ball joint 11. The head 200 is described in further detail in connection with
A fine adjustment mechanism 70 is positioned at the foot end of the pole. In some embodiments, the fine adjustment mechanism is coupled at the foot end of the outermost pole segment 40, that is, the widest segment of the pole. In some embodiments, the fine adjustment mechanism 70 comprises a pedal and thread quick-release mechanism. The structure and operation of the fine adjustment mechanism is described in further detail in connection with
A foot 80 is positioned at the foot end of the pole. The foot 80 includes a lower surface including grips for gripping the surface of the floor. The foot 80 may be, for example, rectangular, square, oval or circular. The foot 80 may include rounded or curved edges. The foot 80 may be of a size such that the foot 80 may be coupled with or rested within a cup or grip disk, as illustrated in
A, compression mechanism, in this case a spring 13 is coupled between the cap 14 and the anchor 15 around an exterior of the rod 12. That is, the rod 12 passes through a longitudinal opening in the spring 13. The anchor and cap 14 may have, for example, a square or rectangular outer profile; however, the present inventive concepts are not limited thereto. In some embodiments, the bottom surface of the ball joint 11 rests on top of, and comes in contact with, cap 14 before the spring 13 becomes fully compressed.
The rod 12 is outwardly biased. Biasing of the rod 12 may be applied, for example, by the compression mechanism or spring 13 that resides in an interior portion of the innermost pole 20. When the rod 12 is pressed in a longitudinal direction into the innermost pole 20, the spring 13 operates to bias the rod 12 in an opposite, outward direction. In this manner, the pole 20 and rod 12, when compressed and mounted between two surfaces, for example between a floor and a ceiling of a room, are outwardly biased toward the floor and ceiling, which secures the pole mount 10 in place.
The rod 12 extends from the head end of the pole mount 10 and travels in a direction along the longitudinal axis of the pole 20 relative to the anchor 15 position within the pole 20. The rod 12 and anchor 15 operate to prevent the rod 12 from being released from the upper end of the innermost pole 20. A stop including washer 16 and nut 17 in the region of the first end of the rod 12 travels in relative motion with the head in the direction along the longitudinal axis of the pole. The stop interfaces with the anchor 15 to limit the outward extension of the rod 12 in the outward direction. In some embodiments, the rod 12 glides freely through the cap 14. In some embodiments, the anchor 15 may be positioned entirely within the innermost segment of the pole 20.
The anchor 15 mounts within the innermost pole 20 such that its position is longitudinally fixed within the innermost pole 20. In some embodiments, the anchor 22 is placed at an appropriate position within the innermost pole 20, and near an upper end of the innermost pole 20, and the outer surface of the innermost pole 20 is dimpled, for example using a punch tool, such that the anchor 15 is pinched between the dimples and thereby secured in place within the innermost pole 20.
The rod 12 slides freely through the anchor 15 and includes the stop, namely, in this embodiment, washer 16 and nut 17, at its first end which interface with the anchor 15 to prevent full release of the rod 12 from the pole 20. The spring 13, supported at one end by the anchor 15, when under compression, exerts an outward biasing force on the rod 12, while at the same time, anchor 15, interfacing with the washer 16 and nut 17, prevents release of the rod 12 from the innermost pole 20.
When an inwardly directed force is exerted on the rod 12, the rod 12 is urged in a direction toward the anchor 15 within the innermost pole 20 and the spring 13 is compressed between spring seats on the bodies of the anchor 15 and the cap 14. The rod 12 slides freely through the anchor 15 to allow for travel of the rod 12 within the pole 20. When the inward force is released, the compression of the spring 13 operates to exert an outwardly directed force on the rod 12, extending the body of rod 12 in a direction outwardly oriented relative to the innermost pole segment 20. In some embodiments, a washer 16 and nut 17 or other physical feature of the rod 12 prevent the rod 12 from being released from the end of the innermost pole 20, thus limiting the outward travel of the rod 12.
In some embodiments, the anchor 15 is retained and secured longitudinally in place within the pole 20 by dimpling the body of the innermost pole 20 into the body of the anchor 15. Alternatively, the anchor 15 may be mechanically riveted, chemically bonded, or otherwise mounted in place within the interior of the pole. In some embodiments, the mechanism used to secure the anchor within an interior portion of the innermost pole 20 does not interfere with the extension and compression of the innermost pole 20 relative to the intermediate pole 30 or outermost pole 40.
In some embodiments, the fine adjustment mechanism 70 includes a pedal and thread quick release mechanism at the foot end of the outermost pole segment 40. The fine adjustment mechanism provides micro-adjustment of the distance between the foot 80 and the foot end of the outermost pole segment 40.

In this manner, when mounting the pole mount 10 between a floor and ceiling of a room, the pole mount can be brought into general position and adjusted in length using the telescoping pole segments 20, 30, 40 and locking mechanisms 50, 60 for coarse adjustment. The underside of the head 200 and the lower flange of the universal joint ball 11 can be fully compressed against the outward force of the compression mechanism 13 so that it is caused to “bottom out” against the cap 14 of the innermost extension pole 20 by pushing the pole mount 10 against the ceiling causing the rod 12 to be pushed into the innermost pole 20. When the underside portion of the universal joint ball 11 abuts the cap 14 of the innermost pole 20, the plunger mechanism is considered to be “bottomed out”, meaning that there is little further room for play or compression in the pole mount 10. At this time, the outermost pole segment 40, and the other pole segments 20, 30 along with it, can be rotated in a first direction relative to the foot 80, causing the outermost pole segment 40 to travel further up the threads of the threaded rod 72 relative to the foot 80. This, in turn, places the pole mount under further compression, applying additional longitudinal compression, since the distance between the underside of the foot 80 and the top of the head 200 is incrementally lengthened between the floor and ceiling. In some embodiments, a grip may be provided along an outer portion of the outermost pole segment 40 to aid in the rotation of the pole mount 10 relative to the foot 80. To later disengage the pole mount 10, the pole segments can be rotated in a second direction, opposite the first direction, relative to the foot 80, causing the distance between the underside of the foot 80 and the top of the head 200 to be incrementally decreased between the floor and ceiling. When the initial pressure due to the rotational adjustment is released, engagement of the pedal 71 causes the mating threaded portions 74 to become disengaged, allowing the foot 80 and threaded rod 72 to float freely relative to the outermost pole segment 40. In some embodiments, the first direction of rotation is illustrated by arrow 84A (see
As the fine adjustment mechanism provides for micro-adjustment of the amount of force imparted by the pole to the ceiling and floor, it is desired that a maximum intended force not be exceeded. Otherwise, damage to the ceiling, floor, or pole system can occur. In some embodiments, the pole mount 10 is configured to withstand approximately 185 lbs. of inward compressive, longitudinal pressure depending on the configuration. In some embodiments, the pole mount 10 is configured to withstand greater or less than approximately 185 lbs. of inward longitudinal pressure depending on the configuration. In some embodiments, the pole mount 10 is configured to withstand approximately 250 lbs. of inward longitudinal pressure depending on the configuration.
In some embodiments the cap 14 applied to an upper portion of the innermost pole segment 20 comprises a compression meter or pressure gauge 14A. The compression meter 14A indicates when a maximum compression force is exceeded. In some embodiments, the compression meter 14A may include a spring 102 (see
In some embodiments, the visual indicator 101 includes a cap 105 and a bottom portion having a smaller diameter than the cap portion 105 which extends into the cap portion 105. The bottom portion includes a first portion 103 and a second portion 104. The spring 102 is formed within cap 105 around rod 12 into a top surface of the first portion 103. In some embodiments, the first portion includes a portion that is a color different from the pole, for example, red. In an uncompressed state, the red portion of the first portion 103 is exterior to the cap 105.

In some embodiments, the visual indicator 101 includes a cap 105 and a bottom portion having a smaller diameter than the cap portion 105 which extends into the cap portion 105. The bottom portion includes a first portion 103 and a second portion 104. The second portion 104 may have the same diameter as the cap 105. The spring 102 is formed within cap 105 around rod 12 into a top surface of the first portion 103. The bottom of cap 105 may have a reflective material 109, for example, reflective tape, thereon, as illustrated in
In the embodiments of
Although in the embodiments illustrated herein, the compression meter 14A or visual indicator 101 is depicted as a mechanical device with a visual identifier as to when a certain compressive force has been applied, in other embodiments, such devices can optionally take the form of a piezoelectric sensor, or other suitable device, that measures force applied to the system and converts the force to an electronic signal. In some embodiments, that signal can be applied to a communication device that indicates to a user information related to the force. For example, the information can indicate the actual force measurement, or indicate whether a force amount has been met or exceeded. The information can be communicated via wire to a digital readout coupled to the pole or, optionally, wirelessly to a wireless device such as a wireless phone or electronic handheld.
The clip 108 is optionally connected to the head 106 by a tether 115, which, in some applications, is desired for preventing separation of a clip from a corresponding head. The tether 115 comprises for example a rope, fastener, wire, cord, chain, strap or plastic attachment. The tether 115 may be removable from either or both of the clip 108 and head 106. Alternatively, the tether 115 may be integral with either, or both, of the clip 108 and head 106.
In
In this embodiment, the head 106 and mating clip 108 extend in a direction that is transverse to the longitudinal axis of the extension pole 20 and plunger 28. The greater the extension of the head, the larger the area of interaction between the head/clip and curtain material, and therefore the stronger the interface. Also, a larger area of interaction prevents the curtain from tearing at the head from stress due to its own weight, or from an externally applied force.
The pole mount of the present inventive concepts provides a pole mount having coarse adjustment and fine adjustment mechanisms and is strong enough to be used in commercial construction. The pole mount of the present inventive concepts may withstand increased compressive strain. In some embodiments, a visual indicator is provided for indicating the point at which a selected degree of compressive strain has been applied.
In the various installation configurations disclosed herein, a top portion of a barrier panel 400, or sheet of material, may be positioned between the head 106 and the clip 108 of the pole mount 10. This may be performed at ground level, by an installer, and, once clipped, can be raised to the ceiling and placed in approximate position. The pole mount 10 can be adjusted in length by the installer using the coarse adjustment mechanism, as illustrated in
The fine adjustment mechanism 70 may then be used to provide micro-adjustment of the pole mount 10. The length of the pole may be adjusted using the fine adjustment mechanism 70 until the visual indicator 101 of the compression meter 14A indicates that a predetermined longitudinally oriented compression force has been applied to the pole system.
In embodiments of the present inventive concepts described herein, the term “floor” and “ceiling” are selected as convenient examples of first and second surfaces between which the pole mount system 10 can be mounted. However, the system is equally applicable to operation between any of first and second surfaces including floor, ceiling, walls, or other structures of a room of a building or an outdoor space, a truck, a tractor trailer, a shipping container, and the like.
While the present inventive concepts have been particularly shown and described above with reference to example embodiments thereof, it will be understood by those of ordinary skill in the art, that various changes in form and detail can be made without departing from the spirit and scope of the present inventive concepts described and defined by the following claims.
