Non-limiting and non-exhaustive embodiments are described with reference to the following Figures, wherein like reference numerals refer to like parts throughout the various views unless otherwise specified.
The support pole assembly 100 generally includes, as shown in
The pole 102 is fabricated from known materials in one or more sections having a generally elongated axial length measured along a longitudinal axis 103 and may be adjustable in length as those in the art will appreciate to accommodate different floor-to-ceiling heights, for example, in use. The pole 102 may be preassembled with multiple sections or may include multiple threaded pole sections that may be assembled on the job site. In a multiple pole section embodiment, the overall length of the combined pole sections may be adjustable, for example, by twisting or sliding one pole section relative to the other to advance the ends of the pole sections toward or away from one another in a telescoping manner, and locking the pole sections in place to maintain a desired axial length of the pole 102. While fabrication of the pole 102 in sections is beneficial for the reasons stated, it is contemplated that the pole 102 in different embodiments may be a single section elongated pole having a fixed length.
The coupler 104 is attached to the distal end of the pole 102 and in the example shown includes threads with which the head attachment 106 may be securely mated. In one contemplated embodiment, the coupler 104 is provided as an adapter that is fitted with a threaded stud 105 provided on the end of the pole 102. In such an embodiment, the coupler 104 includes internal threads having a smaller diameter engaging the smaller diameter stud 105 of the pole 102, and external threads having a larger diameter for engagement with the head attachment 106. By providing such an adaptor as the coupler 104, the pole 102 may be used with other attachments and for other purposes that do not require the coupler 104.
In another embodiment, however, the coupler 104 having the appropriate diameter of threads for coupling with the head attachment 106, may itself be provided on the distal end of the pole in lieu of the stud 105. In such an embodiment, the head attachment may be directly attached to the larger diameter coupler 104 without using any type of adapter.
In still another embodiment, the pole coupler 104 and the stud 105 could be configured so that they could each be used interchangeably with the pole 102. As such, the terminal stud 105 could be removed from the distal end of the pole 102 and replaced with the coupler 104, or the coupler 104 could be removed from the distal end of the pole 102 and replaced with the stud 105. Various other adaptations are possible.
Regardless, in the example shown the threaded engagement of the head attachment 106 and the coupler 104 provides a fixed and rigid structural connection between the pole 102 and the head attachment 106. Once the head attachment 106 is engaged to the threaded coupler 104, the orientation of the head attachment 106 relative to the pole 102 is not adjustable. In other words, and because of the threaded engagement, the head attachment cannot pivot or tilt relative to pole axis 103 at the end of the pole 102 to change the working angle of the head attachment 106 as it engages a ceiling. In other embodiments, however, it is understood that non-threaded couplers could be used that may allow for pivotal or tilted adjustment of the working angle if desired, including but not limited to ball and socket-type coupling techniques familiar to those in the art.
The head attachment 100 generally includes a rectangular body 108 having an upper side or surface 110 and a lower side or surface 112 opposing the upper side 110. The body 108 is provided with a curtain retainer element 114 on the upper side 108 and with a cylindrical attachment flange 116, sometimes referred to as a stem, on the lower side 112. The curtain retainer 114 secures a curtain material (not shown in
The body 108 in the exemplary configuration shown includes a front side 118, a rear side 120 opposing the front side 118, and opposing lateral sides 122, 124 interconnecting the front at rear sides 118, 120. The sides 118, 120, 122, 124 extend generally parallel to the longitudinal axis 103 of the pole 102, are about the same length, and generally impart a square shape to the body 108. The sides 118, 120, 122, 124 also include rounded corners at their ends where the sides meet one another. Other shapes and geometric configurations of the body 108 are, of course, possible in various other embodiments, including but not limited to rectangular shapes having sides of unequal length, other non-rectangular polygonal shapes, and non-polygonal shapes such as circles or ellipses.
The top side or upper side 110 of the body 108 as shown is generally planar and extends in a generally U-shaped configuration as shown in
The rear side 120 of the body 108 is formed with a central opening or cutout 126, and recessed upper surfaces 128 extend between the opening 126 and to the respective lateral sides 122 and 124. As shown in
The retainer element 114, as best seen in
The curtain retainer 114 is formed with a pair of hinge arms 144, 146 extending from the rear edge 138. The hinge arms 144, 146 extend to the opening 126 in the rear wall 120 of the body 108, and the hinge arms 144, 146 are rotatably attached to the rear side 120 of the body 108 at end walls 145, 147 (
As shown in
The retainer element 114 is further provided with a latch element 150 that is movable in a recessed slot 152 formed in the upper side 132 of the retainer 114. The slot 152 and/or the latching element 152 may be formed with guiding an alignment features to provide a slidable motion of the latch element 152 along a linear path in a direction toward or way from the body front side 118 as explained below. As also shown in
In the unlatched position, the leading end 154 of the latching element 152 is spaced from the front side 118 and the upper side 110, and hence does not interfere with or prevent the retainer 114 from being opened. In the latched position, however, the leading end 154 of the latching element 152 extends partly into a slot 160 formed in the front side 160 (
While an exemplary latching element 152 is described, it is recognized that other latching elements are known in the art and may be utilized to retain the door 114 in a closed position and/or to provide further securement of the curtain material in another manner. For example only, magnetic latching features could be utilized in other embodiments.
The lower side 112 of the head attachment 106 includes the generally cylindrical flange 116 as shown in
As mentioned above, while threaded engagement of the coupler 104 and the head attachment 106 is shown in the exemplary embodiment depicted, other types of engagement are possible and may be utilized. For example, ball and socket-type connections are known in the art and may alternatively be utilized, as well as other known socket and coupler arrangements, or other fastening methods whether or not involving a socket, may alternatively be utilized in other embodiments with similar effect to removably couple the head attachment 106 to the pole section 102.
The head attachment 106, including the body 108, the retainer 114 and the latching element 152 may be fabricated from durable molded plastic materials according to known techniques in an exemplary embodiment, although other materials may also be utilized if desired.
By virtue of the hinged connection and the aperture 126 at the rear side 120 of the body 108, the retainer element 114 may pivot or swing upwardly and outwardly away from the upper side 110 of the body 108 from the closed position (
When fully opened, the retainer door 114 beneficially provides clear and unobstructed access to fit the curtain material 200 (
As can be seen from
A temporary partition or wall with the curtain material 200 may be created between opposing walls 306 and 308 of the room 300 to separate one portion of the room from another as shown in
Many configurations of such temporary partitions are possible involving different numbers of poles, different lengths of poles, and different partition materials such as plastic sheets, fabrics, cloths, drapes, tarps, and the like familiar to those in the art. Such partitions may be assembled to extend between adjacent walls in a room, opposing walls in a room, or to partition an area in a room that is not bordered by an existing wall of the room. Openings may be provided, if necessary in the partitions to allow workers to enter or leave partitioned areas.
Like the head attachment 106, the head attachment 400 similarly includes a body 108 that in the exemplary configuration shown includes a front side 118, a rear side 120 opposing the front side 118, and opposing lateral sides 122, 124 interconnecting the front at rear sides 118, 120. The sides 118, 120, 122, 124 generally impart a square shape to the body 108. The sides 118, 120, 122, 124 also include rounded corners at their ends where the sides meet one another. As noted previously, other shapes and geometric configurations of the body 108 are possible in various other embodiments, including but not limited to rectangular shapes having sides of unequal length, other non-rectangular polygonal shapes, and non-polygonal shapes such as circles or ellipses.
Also like the head attachment 106, the top side or upper side 110 of the body 108 of the head attachment 400 as shown is generally planar and extends in a plane generally perpendicular to the axis of the pole (such as the axis 103 of the pole 102 shown in
A gasket 402 is applied to the upper side 110 of the head attachment 400, and in the exemplary embodiment shown, the gasket 402 includes a non-slip upper surface that is elevated from the upper side. The gasket 402 further extends in a U-shaped configuration extending on the upper surface 110 entirely across the front side 118, most of the lateral sides 122, 124, but not across the rear side 120. As such, the rear side 120 has an upper surface that is recessed from the upper surface of the gasket 402. As such, when the upper surface of the gasket 402 is engaged to a ceiling or other object in use, the upper surface of the rear side 120 does not engage the ceiling or other object.
As shown in
The curtain retainer 114 is constructed, installed, and operable in a similar manner for the head attachment 400 as described above for the head attachment 406, with similar benefits and advantages.
The above-described head attachments and pole assemblies are believed to be particularly advantageous and beneficial over existing head attachments and pole assemblies. The retainer elements described are believed to be easier to use than some conventionally provided retainers, and also are believed to be more durable and may be manufactured at lower cost. The described head attachments and retainers are believed to be particularly advantageous for securing partition materials to the temporary support pole sections, but it is contemplated that other materials, items, and articles may likewise be reliably secured to the head attachments for purposes other than erecting temporary partitions. As such, the invention is not believed to be solely limited in application to securing flexible partition materials. The benefits of the invention are believed to be equally applicable to non-partition applications and the present disclosure is not intended to preclude such possibilities.
While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
