Description

BACKGROUND OF THE INVENTION

The present invention relates to a leveler, and more particularly to a leveler for upright panel systems such as those used in connection with office furniture systems.

Upright office panels are commonly used to divide a larger office spaces into a series of smaller, usable spaces, such as offices, meeting rooms and corridors. Due to inconsistencies and undulations in flooring, these office panels may be provided with a degree of adjustment to keep the panels plumb, especially when the panels are arranged in an elongated straight line.

One adjustment option that is known in the prior art is the threaded glide. As depicted in FIG. 1, in this design, the panel (not shown) is supported by one or more vertical uprights 100, which extends upwardly from a generally horizontal foot 102. A pair of threaded glides 103, 104 extend between the floor 105 and opposite ends of the foot 102. In order to account for the uneven height of the floor surface 105, the glides 103, 104 may be independently adjusted by threading the glides into or out of the foot to vary the distance between the head 106 of the glide 103, 104 and the foot 102. For example, FIG. 1 shows a situation where the glide 104 is threaded into the foot 102 a lesser amount than glide 103 to increase the distance between the head 106 of glide 104 and the foot 102 to account for the uneven surface of the floor 105 and generally maintain the verticality of the upright 100. A downside of this construction is the need for a relatively significant minimum thickness/height of the foot 102 in order to accommodate the threaded glide. In general, enough thickness for at least three threads of the glide 103, 104 are needed in order to provide sufficient adjustability. This thickness can be unsightly, a trip hazard, and can interfere with the positioning of adjacent structures such as desks and storage.

SUMMARY OF THE INVENTION

The present invention provides the advantages of adjustability for a panel system in a low-profile design.

In one embodiment, the present invention includes a foot, an upright leg for supporting an object such as a panel, and an upright adjustment mechanism disposed above the foot and between the foot and the upright leg to enable adjustment of the angle of the upright leg with respect to the foot. In one embodiment, the upright adjustment mechanism includes a generally horizontal pin extending through a portion of the upright leg, such that the upright leg can pivot about the pin with respect to the foot. In a more specific embodiment, the upright adjustment mechanism includes a tubular support extending upwardly from the foot. A portion of the upright leg extends into the opening of the tubular support. The pin extends through the tubular support and the portion of the upright leg such that the leg can pivot within the tubular support. A pair of set screws may extend into opposing sides of the tubular support and into engagement with opposing walls of the lower portion of the upright leg to enable the angle of the upright leg to be set at a desired angle for leveling the panel.

This design enables a low profile foot, because the foot does not need adjustable glides, and the foot does not need a thickness that accommodates for the threads of the glides. These and other objects, advantages, and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiments and the drawings.

DETAILED DESCRIPTION OF THE CURRENT EMBODIMENT

Referring to FIGS. 2-3, a leveler leg is shown and generally designated 10. The leveler leg 10 includes an upright leg assembly 11, a foot 9 and an upright adjustment mechanism 12. The upright adjustment mechanism 12 connects the upright leg assembly 11 to the foot 9 in such a way that the angle of the upright with respect to the foot may be adjusted.

In one embodiment, the foot 9 is a generally low-profile elongated plate having a lower ground engaging surface and an upper surface 13 opposite the ground engaging surface. The foot 9 may include a first end 14 and a second end 15 opposite the first end, such that the foot 9 defines a length between the first 14 and second 15 ends. The length of the foot may be varied from application to application.

The upright assembly 11 includes one or more members extending upwardly from the foot 9. Although not shown, the upper end of the upright assembly may be connected to one of a variety of items for supporting the item. For example, the upper end of the upright assembly 11 may connect to one side of a furniture panel for supporting the furniture panel in an upright position. This furniture panel may be one in a series of furniture panels mounted end to end to form a wall or corridor, wherein each of the screens is supported by an upright assembly 11. In the illustrated embodiment, the upright assembly 11 includes an inner structural leg member 3, a bracket plate 2 and bracket 1 mounted to the inner structural leg member 3, an upper cover 4 and a slidable cover 5. It will be noted that in another, more simplified, embodiment, the upright assembly may include only a single vertical support, such as the structural leg member 3, extending between the adjustment mechanism 12 and the bracket plate 2.

In one embodiment, the upright adjustment mechanism 12 includes a tubular support 8 extending upwardly from the upper surface 13 of the foot 9 and defining an internal opening, an adjustment block 7 extending into the opening of the tubular support 8, a threaded rod 6 extending upwardly from the adjustment block 7, a pivot pin 20, and a setting element, such as a pair of set screws 22, 24. As shown in FIG. 2, the tubular member 8 may include a first set of through holes 26 extending through left and right side surfaces of the tubular member 8, and a second set of through holes 28 extending through front and rear surfaces of the tubular member 8. The adjustment block 7 may also include a through hole 30 extending through the left and right side surfaces. Referring to FIG. 3, the pivot pin 20 extends through the through holes 28 in the tubular member 8 and through the through hole 30 in the adjustment block 7 such that the adjustment block 7 can pivot about the pivot pin 20 with respect to the tubular member 8. More particularly, in the illustrated embodiment, the pivot pin 30 extends perpendicular to the length of the foot 9, such that the adjustment block 7 pivots in the direction of the length of the foot 9. The set screws 22, 24 may extend into the through holes 28 in the front and rear surfaces of the tubular member 8. In this way, the set screws may be adjusted to set the angle of incline of the upright assembly 11 with respect to the foot 9. Depending on the depth of the respective set screws 22, 24, the upright assembly 11 may be set to a desired angle in the direction of either the first end 15 or the second end 14 of the foot 9. In an alternative embodiment, the set screws 22, 24 may be replaced by other structure that can retain the block 7 or the upright assembly 11 in a desired position.

In the illustrated embodiment, the upright assembly also enables height adjustment. In this embodiment, the threaded rod 6 threads into a receiving threaded portion (not shown) which is located in the inner structural tube 3. The threaded rod 6 may be rotated with respect to the structural leg 3 in order to adjust the height of the structural leg 3. A jam nut 32 threads onto the threaded rod 6 to engage the receiving threaded portion in order to prevent the adjustment mechanism from spinning after the desired height is achieved.

The upright assembly may also include one or more covers to enhance the aesthetic appeal of the leveler leg 10. As shown, the upper cover 4 extends over the inner structural leg 3 and abuts the plate 2. The upper cover may be fixed with respect to the structural leg 3. The slidable cover 5 may extend over a portion of the upper cover 4 and over the tubular member 8 to cover and hide the functional aspects of the upright adjustment mechanism 12. The slidable cover 5 may be movable by a user to slide up over the upper cover 4 to expose the tubular member to enable adjustment of the set screws 22, 24 and the upright adjustment mechanism 12.

In operation, the bracket 1 of a leveler leg 10 is mounted to an item, such as an upright modular panel for a furniture panel system or to a privacy screen, by a conventional method. For example, the bracket 1 may be bolted or otherwise attached to a lower portion of a furniture panel. In one embodiment, the bracket 1 of a first leg 10 is bolted to one side of a furniture panel and the bracket 1 of a second leg 10 is bolted to the other side of a furniture panel such that one leg 10 supports the joint of two furniture panels. More particularly, different configurations of bracket 1 may be provided to more efficiently support different furniture panel arrangements. Of course, in an alternative embodiment the leg 1 may include a differently shaped bracket 1 or a different structure altogether for attaching to the furniture panel, and in another embodiment the leg 1 may support a completely different item, such as a worksurface.

The foot 9 of each leg 1 is placed on a floor surface and measured with respect to level. In the event that the foot is not level, or in the event that one end of the foot 9 is not in contact with the floor, the upright leveler mechanism 12 can be manipulated by a user to change the angle of the upright assembly 11 with respect to the foot 9 in order to bring the system to level. In order to do so, the user may lift the slidable cover 5 (to the extent that the product includes the slidable cover 5), and access the set screws 22, 24 to loosen the set screws 22, 24. Once the set screws are loosened, the angle of the foot can be adjusted by pivoting the block 7 about the pivot pin 20 in the direction of the length of the foot 9 (i.e., toward or away from one of the ends 14, 15). The nature of the pivot pin prevents movement of the block 7 or upright assembly 11 in any other direction. The angle of the foot 9 is adjusted until level, and then the set screws 22, 24 are tightened against the block 7 to retain the block 7 in position and thus retain the angle of the upright assembly in the desired level position.

In the event that the leg 10 includes height adjustability, such as the threaded rod 9 of the illustrated embodiment, the height of the upright assembly 11 may be adjusted by manipulating the height adjuster, such as by rotating the threaded rod 6 with respect to the threaded portion in the structural leg 3.

FIGS. 4 and 5 show alternative embodiments for setting the upright adjustment mechanism at the desired angle. In particular, FIG. 4 shows the set screws 22, 24 replaced by bolts 22′, 24′. The bolts 22′, 24′ may thread into and out of the block 7 for setting the angle of the upright assembly 11, rather than simply abutting the outer surface of the block 7 in the manner of the set screws 22, 24. FIG. 5 shows a single bolt 24″ that may thread into and out of the block 7 for setting the angle of the upright assembly 11.

FIGS. 2, 6 and 7 show variations of the plate 2 and bracket 1 for use in supporting furniture panels in different configurations. For example, FIG. 2 shows a plate 2 and bracket 1 for use in inline and end of run furniture panel configurations such as those shown in FIGS. 8-10. In the FIG. 2 embodiment, the plate 2 partially offsets the bracket 1 from the upright leg 3, 4 such that an inner edge 37 of the bracket 1 is aligned under a joint 35 between then uprights 56 of adjacent furniture panels 52, 54, wherein one furniture panel 52 is attached to the bracket 1 and the other furniture panel 54 is attached directly to the furniture panel 52, enabling a single leg 10 to support both furniture panels 52, 54 in the inline configuration. In addition, this same plate 2 and bracket 1 configuration can be used in on opposing ends of the inline configuration by rotating one of the end of line legs 10 180 degrees from the other (as shown in FIG. 9). In such an inline orientation, the feet 9 of the respective leveler legs 10 are oriented at approximately a 90 degree angle to the furniture panel sections 52, 54. FIG. 10 illustrates this embodiment with the feet 9 removed for purposes of illustrating the location of the leveler legs 10.

FIG. 6 shows a rear perspective view of a portion of the leveler leg 10 with the plate 2 and bracket 1 configured for attaching furniture panels at a 90 degree angle from one another such as that shown in FIGS. 11-13. In this embodiment of the plate 2 and bracket 1, the plate 2 completely offsets the bracket 1 from the upright leg 3, 4 such that an inner edge 37 of the bracket 1 is aligned generally under a side 41 of the upright leg 4, enabling a single leg 10 to support two, three or four furniture panels 52, 54 in a 90 degree configuration as shown in FIGS. 11-13 and 16 with the upright leg 3, 4 centered between the uprights 56 of the furniture panels 52, 52 and underneath the furniture panel connectors 59. To provide additional support for the bracket 1 in this embodiment with a greater offset from plate 2, the leg 10 may include a support gusset 39 extending between the plate 2 and bracket 1. As shown in FIG. 16, a leg 10 with the 90 degree embodiment is shown in the middle of the unit (illustrated with the foot 9 removed), supporting the uprights 56 of both panels 52, 54. The ends of the panels 52, 42 are supported by legs of the inline/end of run embodiment as shown in FIG. 2.

FIG. 7 shows a rear perspective view of a third variation of the bracket 1 and plate 2 wherein the plate 2 provides an offset at an angle from the structural leg 3, 4 and the foot 9 for orienting items such as furniture panels at a 120 degree orientation with respect to one another. For example, in this embodiment, the plate 1 may include a first portion 21 extending in a first direction and a second portion 23 extending at about a 120 degree angle from the first portion 21. This embodiment may also provide a support gusset 39. As in the 90 degree embodiment of FIG. 6, in this FIG. 7 embodiment the bracket 1 may be completely offset from the leg 4. FIGS. 14, 15 and 17 show the leveler leg 10 of the FIG. 7 configuration supporting furniture panels 50 oriented at 120 degree angles from each other. In particular, FIG. 14 shows a 2-way connection at a 120 degree angle and FIG. 15 shows a 3-way connection at 120 degree angles. In each of these views the foot 9 of the leveler leg 10 is removed for purposes of illustrating the location of the leveler leg 10. It should be recognized that the foot 9 may be oriented in any direction with respect to the various furniture panels 50, and will generally be oriented at an angle to two of the screens 50 forming the connection. Referring now to FIG. 17, as in the inline and 90 degree configurations noted above, in the embodiment with a 120 degree configuration (shown on the middle leg 10 in FIG. 17), the offset provided by the plate 2 enables a single leveler leg 10 to support the uprights 56 of multiple furniture panels 50 with the upright 4 aligned underneath the connectors 59 extending between adjacent panel uprights 56.
