BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to height adjustable tables. More particularly, the present invention relates to an improved height adjustable table that includes specially configured telescoping legs that enable the table to be supported without the use of any obstructive supports that are typically placed in an intermediate position between a supported table top and a floor or other underlying support surface. Further, the present invention provides an improved telescoping leg arrangement that enables manual and/or motorized operation of the telescoping legs.

2. General Background of the Invention

Height adjustable tables enable different users to comfortably use the table notwithstanding differences in height. Additionally, height adjustable tables enable a user to vary the elevation of the table depending upon the activity being conducted. For example, a user might choose a first elevation of a table top when operating a computer. That person might set the table at a different height or elevation when reading a book.

Some height adjustables have been patented. The following table lists patents that have issued and that relate to height adjustable tables.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1-13 show a preferred embodiment of the apparatus of the present invention, designated generally by the numeral 10. Height adjustable table 10 provides an expansive top 11 having a work surface 12. Top 11 can be supported with a pair of spaced apart legs 13, 14. Each leg 13, 14 is joined to a foot. The leg 13 connects to foot 15. The leg 14 connects to foot 16.

Table 10 can be height adjusted using crank 17. Crank 17 is joined to a crank rod 18 that can be rotated as illustrated by arrow 19 in the drawings. The rod 18 is supported using rod support 20. Rod 18 also extends to a structural gear box housing 21 as shown in FIGS. 1 and 7.

Each leg 13 has a lower section 23 and an upper section 24. The upper section 24 moves up and down relative to lower section 23 as illustrated by arrow 25 in FIG. 2. FIG. 1 illustrates a collapsed lowermost position of upper section 24. FIG. 2 illustrates an upper elevated position of upper section 24.

Rod 26 extends between gear box housings 21, 22. The gear box housing 21 is associated with leg 14. The gear box housing 22 is associated with leg 13. Each of the gear box housings 21, 22 provides a gear box arrangement as shown in FIGS. 6 and 7. Each gear box housing 21, 22 includes a gear cluster 32. The gear cluster 32 includes a bevel gear 35 mounted at the upper end portion of externally threaded shaft 36. The gear cluster 32 also includes a bevel gear 33 mounted upon an end of crank rod 18. For the gear box housing 22, it should be understood that there would not be a rod 18 nor bevel gear 33. Instead, the gear box housing 22 would contain an externally threaded shaft 36 having bevel gear 35 and a bevel gear 34 mounted to an end portion of rod 26 that enters gear box housing 22.

In FIG. 6, crank rod 18 can provide a rod telescoping section 27. The rod telescoping section 27 can include a stop pin 28 that travels in slot 29, as shown in FIG. 3. In this fashion, the crank 17 can be moved from a retracted position as shown in hard lines in FIG. 3 to a operating position as shown in phantom lines in FIG. 3 and in hard lines in FIGS. 2 and 6. Arrow 30 in FIG. 3 illustrates movement of crank 17 between retracted and extended, operating positions. In FIG. 6, fasteners 31 can be used to secure gear box housing 21 and rod support 20 to the underside of expansive top 11. Similarly, fasteners 31 can be used to secure gear box housing 22 to the underside of expansive top 11.

In FIGS. 6 and 6A, externally threaded shaft 36 has a lower end portion 37 that is fitted with stop 38. Internally threaded sleeve 39 provides an internally threaded nut 40 that engages externally threaded shaft 36 as shown in FIG. 6A. When stop 38 engages internally threaded nut 40, maximum elevation of expansive top 11 is reached. Upper leg section 24 provides an upper tube 41. Lower leg section 23 provides a lower tube 42. A support sleeve 43 can be placed in between the lower end portion of the upper tube 41 and upper end portion of the internally threaded sleeve 39 (see FIG. 6). The sleeve 39 can be a square tube, for example.

A foot 16 provides socket 44 that is receptive of lower tube 42 as shown in FIG. 6. Fasteners 45 form a connection between foot 16 and plate 46. Plate 46 can be fastened to the lower end portion of tube 42 using welding, for example. A lower threaded nut 47 is embedded within the lower end portion of tube 39. Fastener 48 centers tube 39 upon plate 46 and thus centers tube 39 with respect to tube 42 as shown in FIG. 6. Foot 15 or 16 can provide one or more casters 49 or fixed supports 50, or one of each. In FIG. 6, a structurally robust connection is made between upper tube 41 and gear box housing 21. Each gear box housing 21, 22 is generally bowl shaped, extending in front of and behind as well as on both sided of the gear box that is envelops. A peripheral edge of each housing is joined to the table top along a circumferentially spaced, radially spaced position relative to a leg and gearbox that it surrounds and envelops. A circular plate 63 provides an opening 64 through which externally threaded shaft 36 can pass. A connection 65 between tube 41 and gear box housing 21 can be for example a welded connection that includes welding to circular plate 63. This connection enhances the moment load transfer capability between upper tube 41 to expansive top 11 over an elongated area designated by the dimension arrow 66 in FIG. 6. This arrangement thus eliminates the need for intermediate bracing which is typically found in the prior art, and that interferes with the knees of a user and/or with the storage of large items in the area under the table top 11, such as computers.

FIGS. 8-13 show a guiding arrangement that interfaces upper tube 41 and lower tube 42. Guides 51 are placed at circumferentially spaced apart positions on upper tube 41 as shown in FIG. 10. In FIGS. 11 and 12, each guide 51 has an elongated center section 52, and enlarged upper section 53 and an enlarged lower section 54. Each enlarged section 53, 54 provides a lug 55. The lugs 55 enable each guide 51 to be mounted to sockets or openings in upper tube 41.

Rib 56 is provided in each enlarged section 53, 54 opposite lug 55 as shown in FIGS. 11 and 12. The ribs 56 travel in channels 58 formed on the inside surface of lower tube 42.

Slides 59 are mounted in openings 62 in lower tube 42. Each slide 59 has an inner concave surface 60. Each slide 59 provides a lug 61 for attaching to socket or opening 62 in lower tube 42.

FIGS. 14 and 15 show a second embodiment of the apparatus of the present invention, designated generally by the numeral 10A. Height adjustable table 10A is similar to the preferred embodiment of FIGS. 1-13. In FIGS. 14 and 15 however, a curved expansive top 11A is provided having a work surface 12A. Height adjustable table 10A provides three legs 13, 14, 80. Each of the legs 13, 14, 80 can be constructed in accordance with the preferred embodiment of FIGS. 1-13. The leg 80 provides a single wheeled caster 49, while the feet 15, 16 can provide either a caster 49 or a fixed support 50 as shown in FIG. 6.

In FIG. 15, height adjustable table 10A provides three gear box housings 21, 22 and 69. The gear box housings 21, 22 are constructed in accordance with the preferred embodiment of FIGS. 1-13. The gear box 69 forms an interface between two rods 67, 68. This arrangement is similar to that shown in FIG. 7. However, the rods 67, 68 form an obtuse angle as opposed to a ninety degree or right angle. In that regard, each rod 67, 68 provides bevel gears 33 or 34 at each end portion which engage a bevel gear 35 of an externally threaded rod 36.

FIGS. 16-19 and 22-23 show a third embodiment of the apparatus of the present invention, designated generally by the numeral 10C. Height adjustable table 10C employs a telescoping leg 70 that can be used for a two-legged table (FIG. 18), a three-legged table (FIG. 22), or a table having more than three legs (FIG. 23). In FIG. 16, telescoping leg 70 includes an upper elevating section 71 and a lower static section 72. A third leg section is an outer tube 73 that is also static and that surrounds the combination of upper elevating section 71 and lower static section 72. This arrangement of the three sections can be seen in FIGS. 16 and 17.

Externally threaded shaft 75 extends from gear box housing 79 downwardly to internally threaded nut 74 which is mounted in the upper end portion of lower static section 72, as shown in FIG. 17. The lower end of externally threaded shaft 75 provides a stop 76. When elevating the table 10C, expansive top 81 and its work surface 82, a maximum elevation is reached when stop 76 contacts internally threaded nut 74.

Leg 70 can be mounted in a foot such as 15 or 16 using a connection similar to that shown in FIG. 6. In FIG. 16, plate 77 is provided at the lower end portion of lower static section 72. Fasteners 78 can extend through openings in foot 15, 16 to connect with plate 77. In that regard, plate 77 can have multiple internally threaded sockets that are receptive of fasteners 78.

Gear box housing 79 preferably extends a distance 66 that is about equal to or greater than one half the depth of expansive top 81, as shown in FIG. 16. As with the preferred embodiment, a robust connection is formed between leg 70 and gear box housing 79. Gear box housing 79 connects to upper elevating section 71 at circular plate 83. Plate 83 has an opening 84 that enables externally threaded shaft 75 to extend through plate 83 and engage motor drive 90, as will be described more fully hereinafter. A welded or like connection can be formed between the three parts that include gear box housing 79, circular plate 73, and upper elevating section 71 of leg 70. As with the preferred embodiment, this connection enables a high moment load transfer between table top 81 and leg 70, eliminating the need for intermediate supports between legs and below the top 81.

The outer tube 73 is a static tube that is connected to a foot 15 or 16 using adhesive, an interference fit, a threaded connection, or other connection such as a friction fit using for example one or more set screws 85 (see FIG. 16). The upper elevating section 71 thus travels in between lower static section 72 and outer tube 73. The outer tube 70 can be provided in a number of different colors so that a user can match table 10C of the present invention to a selected decor.

In the embodiment of FIGS. 16-19, a motor drive 90 is provided for each gear box housing 79 associated with each leg 70. For the table 10C shown in FIG. 18, there are two legs 70, two gear box housings 79, and two motor drives 90. FIG. 19 illustrates the details of construction of motor drive 90. The motor drive 90 includes an electric motor 86 having a motor shaft 87 fitted with a worm gear 88. Worm gear 88 engages pinion gear 89 that is mounted to the upper end of externally threaded shaft 75. For the embodiment of FIGS. 16-18, each leg 70 has a motor drive 90. Those motor drives 90 are synchronized so that when a user activates operating panel 91, the legs 70 selectively elevate at the same time (using keypad arrow 92) and at the same rate or descend at the same time (using keypad arrow 93) and at the same rate.

FIGS. 20, 24 and 25 illustrate that different controllers can be used. In FIG. 20, up arrow 92 and down arrow 93 are provided for enabling an operator to elevate or descend expansive top 81. Keypad numerals 94, 95, 96 enable an operator to input a code that “remembers” the position of the table top 81, such as for example when several users are using table 10C at different times. The key number “s”, designated by numeral 97 provides a “set” function that identifies a certain code with a certain elevation of a table after a user has input a selected code using the keys 94-96.

FIG. 24 is a simpler arrangement, where only up and down arrows 92, 93 are provided. FIG. 25 is similar to FIG. 20 with the addition of a digital readout 98.

FIGS. 22 and 23 illustrate that multiple legs 70 can be employed, such as three legs 70 of FIG. 22 or even more legs in FIG. 23, in that the motor drives 90 are synchronized.

The following is a list of parts and materials suitable for use in the present invention.
