Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of U.S. provisional patent application Ser. No. 60/790,747, which was filed on Apr. 10, 2006 and entitled TABLE, which is incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention generally relates to furniture and, in particular, to tables.
2. Description of Related Art
Conventional tables are used for a variety of purposes and come in a wide array of designs. In some situations, it is desirable to have a smaller table for personal or individual use. These smaller-sized tables intended for use by a single person may be referred to as a personal table. For example, persons living in a small space, such as a studio apartment, may choose to use a smaller or personal sized table on which to dine or perform tasks such as reading, working or writing. These smaller or personal sized tables can also be used to hold objects such as computers, televisions and other electronic equipment.
Known tables often include a table top that is permanently fixed in a particular location and configuration. In addition, known tables typically include a table top that is disposed in a level orientation in which the upper surface of the table is generally parallel to a support surface such as the ground or floor. A level orientation, however, may not be best suited for certain uses of the table.
Known tables may also be adjustable. For example, the height of some known tables may be adjustable. Additionally, the orientation of the table top for some known tables may be adjustable. Disadvantageously, it may be rather time consuming and difficult to adjust the height or orientation of the table top of some conventional tables. For example, adjusting the orientation of the table top of some conventional tables may require the loosening and tightening of a knob or fastener, which can make adjusting the orientation of the table tops difficult, awkward and time consuming.

BRIEF SUMMARY OF EMBODIMENTS OF THE INVENTION

One aspect is a table that may include a table top that is movable between an extended or use position and a collapsed or storage position. The table may also include a frame that is sized and configured to support the table top, and the frame may be movable between an extended or use position and a collapsed or storage position. With the table top and the frame in the collapsed positions, the table may advantageously be disposed in a relatively compact. Significantly, this may allow the table to be stored in a smaller area and it may allow the table to be more efficiently shipped in smaller packaging.
Another aspect is a table that may include a table top and a frame which can be separately movable between extended and collapsed positions. For example, when storage of the table is desired, the table top may be moved from the extended position to the collapsed position and then a portion of the frame may be moved from the extended position to the collapsed position. When use of the table is desired, the lower portion of the frame may be moved to back to its extended position and then the table top may be moved back to its extended position. Advantageously, the table top and the frame may be moved between the collapsed and extended positions in any desired order, which may increase the potential uses of the time. In addition, the table top and frame may be simultaneously moved between the collapsed and extended positions, if desired.
Still another aspect is a table that may include one or more wheels, which may be sized and configured to allow the table to be quickly and easily moved. Significantly, the wheels may be used when the table top and/or frame are in the extended or use positions. For example, when the table top and frame are in the extended positions, the wheels may be used to allow the table to be quickly and easily moved from one location to another location. On the other hand, the wheels may allow the table to be quickly and easily moved when the table top and frame are in the collapsed positions. One or more of the wheels may also be spaced apart from a support surface when the table top and/or frame are in the extended or use positions. For instance, the wheels may be spaced apart from the support surface when the table top and frame are in the extended and/or use positions to prevent the table from inadvertently moving.
Yet another aspect is a table that may include table top with a first section and a second section. The first and second sections are preferably movable relative to each other to allow the configuration of the table top to be adjusted. For example, the second table top section may be sized and configured to rotate, pivot, tilt and/or move relative to the first table top section. In addition, both the first and second sections of the table top may be adjustable. For instance, the first and second sections may be sized and configured to rotate, pivot, tilt and/or move in one or more directions. Advantageously, if the table top includes movable sections, then that may allow the table to accommodate a variety of different users and be used for a number of purposes and functions.
A further aspect is a table that may include a table top with first and second sections in which the second section is sized and configured to rotate, pivot, tilt and/or move between a first position in which the first and second table top are generally aligned and a second position in which the second table top section is positioned at an angle relative to the first table top section. Advantageously, when the second table top section is in the second position, the first and second table top sections may be positioned for different uses. For example, the first table top section could be positioned in a generally level or horizontal position and pencils, pens, rulers, books and/or other items may rest upon this section of the table top. The second table top section, however, may be disposed at an angle relative to the first table top section. This may allow, for example, the second section to support items at an angle. Advantageously, this may allow items such as a laptop computer to be disposed in an ergonomically beneficial position. Of course, the table top sections may be disposed in other positions and may be used for a variety of other purposes and functions.
A still further aspect is a table that may include a table top with first and second sections in which the second table top section may be sized and configured to rotate, pivot, tilt and/or within a limited range relative to the first table top section. Limiting the movement of the second table top section relative to the first table top section may advantageously help ensure that the second table top section is used for a particular, purpose or function. For example, if the movement of the second table top section is limited to about 15 degrees relative to the first table top section, then that may help prevent items from unintentionally sliding off the table top. In addition, limiting the movement of the table top sections may allow items such as laptop computers to be disposed in ergonomically beneficial positions. It will be appreciated that the movement of the table top sections need not be limited to about 15 degrees. In contrast, the table top sections may be limited to larger or smaller angles or positions depending, for example, upon the intended use of the table or table top sections.
Yet another further aspect is a table that may include a table top with first and section sections in which the table top sections may be sized and configured to rotate, pivot, tilt and/or move without tightening and/or loosening of a knob or fastener. For example, the table top may include a ratcheting mechanism that is sized and configured to allow the position of the second table top section to be incrementally adjusted without tightening and/or loosening a knob or fastener. In addition, one or more portions of the table, such as the frame or table top, may help create a friction, snap and/or interference fit that allows the position of the second table top section to be incrementally adjusted without tightening and/or loosening a knob or fastener.
Another aspect is a table that may be adjustable in height. In particular, the table top that may be sized and configured to be movable between a plurality of different heights. For example, the table top may move between a first position in which the table top is positioned at a first height and a second position in which the table top is positioned at a second height.
Still another aspect is a table that may include a height adjustment mechanism which is sized and configured to adjust the height of the table top between the plurality of different heights. The height adjustment mechanism is preferably sized and configured to be operated with one hand or one foot. For example, the height adjustment mechanism may include a trigger (such as a button, lever, handle or the like) that may be operated with one hand to lock and/or unlock the table top at a desired height. Also, for example, the height adjustment mechanism may include a trigger (such as a foot pedal) that may be operated with one foot to lock and/or unlock the table top at a desired height.
Yet another aspect is a table that may include a height adjustment mechanism which is sized and configured to adjust the height of the table top in a generally smooth fashion. For example, the height adjustment mechanism may include a spring (such as a gas spring, a coiled spring or the like) which may advantageously allow the height of the table top to be adjusted in a generally smooth fashion.
A further aspect is a table that may have a relatively small-sized table top that is designed for use by a single person. This type of table that is intended for use by an individual may be referred to as a personal table, but it will be appreciated that more than one person could use the table if desired. Advantageously, the personal table may be relatively small and light-weight, which may make the table relatively easy to move and transport. Significantly, because the table may be sized and configured for personal use, it may not take up unnecessary space or provide a large amount of unused space. Therefore, the personal table may provide ample space for a single user without requiring a large area or wasting unnecessary space.
A still further aspect is a table that may be used for a wide variety of different situations, purposes and uses. For example, the table may be used for supporting a television, computer, sewing machine, microwave, lamp, luggage and the like. The table can also be used for a wide variety of other uses such as a bedside table, coffee table, night stand, desk, shop table and the like. Further, the table can be used while performing a wide variety of tasks such as reading, writing, studying, working, etc. Thus, the table can be used in a number of different environments and it can perform numerous different tasks.
Yet another further aspect is a table that may include a table top constructed from lightweight material so that the table is easily portable and can be readily lifted and moved by a single person. Desirably, the table top is constructed from blow-molded plastic, such as high density polyethylene. The blow-molded plastic table top may provide a relatively rigid, high-strength structure that is capable of withstanding repeated use and wear. Advantageously, the blow-molded table top may be easily manufactured and formed into the desired size and shape. The blow-molded plastic table top preferably includes a hollow interior portion, which may help form the relatively lightweight table top. Advantageously, the blow-molded table top may include one or more features that are integrally formed in the table top as part of a unitary, one-piece structure. For example, the bottom of the table top may include one or more grooves, channels and the like, which may be sized and configured to receive and/or retain a portion of the table such as the legs and/or frame.
Another aspect is a table that may include a table top and one or more legs that are sized and configured to support the table top at a desired height. The legs are preferably offset towards one side of the table top. Advantageously, because the legs are not placed in the center of the table, that may provide increased legroom for the user. This also may allow the table top to be positioned closer to the body of the user, which may be more convenient for the user.
These and other aspects, features and advantages of the present invention will become more fully apparent from the following detailed description of preferred embodiments and appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is generally directed towards a table. The principles of the present invention, however, are not limited to tables. It will be understood that, in light of the present disclosure, the table disclosed herein can be successfully used in connection with other types of furniture.
Additionally, to assist in the description of the table, words such as top, bottom, front, rear, right and left may be used to describe the accompanying figures, which are not necessarily drawn to scale. It will be appreciated, however, that the table can be located in a variety of desired positions—including various angles, sideways and even upside down. A detailed description of the table now follows.
As shown in FIGS. 1-2, an exemplary table 10 is preferably a relatively small-sized table that is designed for use by a single person. This type of table that is intended for use by an individual may be referred to as a personal table, but it will be appreciated that more than one person could use the table 10 if desired. Advantageously, the personal table 10 may be relatively small and light-weight, which may make the table relatively easy to move and transport. Significantly, because the table 10 may be sized and configured for personal use, it may not take up unnecessary space or provide a large amount of unused space. Therefore, the personal table 10 may provide ample space for a single user without requiring a large area or wasting unnecessary space. In addition, the personal table 10 can be used for a wide variety of different situations and uses such as a table for supporting a television, computer, sewing machine, microwave, lamp, luggage and the like. The table 10 can also be used for a wide variety of other uses such as a bedside table, coffee table, night stand, desk, shop table and the like. Further, the table 10 can be used while performing a wide variety of tasks such as reading, writing, studying, working, etc. Thus, the personal table 10 can be used in a number of different environments and it can perform numerous different tasks. It will be appreciated, however, that the table 10 need not be a personal table and that the table may have a variety of other suitable shapes, sizes, configurations and arrangements.
As shown in FIGS. 1-2, the table 10 may include a table top 12. The table top 12 may be constructed from a lightweight material so that the table 10 is easily portable and can be readily lifted and moved by a single person. Desirably, the table top 12 is constructed from blow-molded plastic, such as high density polyethylene. The blow-molded plastic table top 12 may provide a relatively rigid, high-strength structure that is capable of withstanding repeated use and wear. Advantageously, the blow-molded table top may be easily manufactured and formed into the desired size and shape. The blow-molded plastic table top 12 preferably includes a hollow interior portion, which may help the table top to be relatively lightweight. It will be appreciated, however, that the table top 12 may be constructed using other suitable materials and/or other processes.
The table 10 may also include a frame 14 that is sized and configured to support the table top 12. The frame 14 may include an upper portion 16, a lower portion 18 and an intermediate portion 20 disposed between the upper and lower portions of the frame. The frame 14 and its components are preferably constructed from metal, such as steel. It will be appreciated, however, that the frame 14 and its components may be constructed from other suitable materials.
The intermediate portion 20 of the frame may include one or more legs and the legs may be offset towards one side of the table top 12. Advantageously, if the legs are not placed in the center of the table 10, that may provide increased legroom for the user. This may also allow the table top 12 to be positioned closer to the body of the user, which may be more convenient for the user. It will be appreciated, however, that the legs and the intermediate portion 20 need not be offset towards one side of the table top 12 and may be positioned in any desired location.
As shown in FIGS. 3-6, the table top 12 and the frame 14 may be movable between an extended or use position and a collapsed or storage position. With the table top 12 and the frame 14 in the collapsed or storage position, the table 10 may advantageously be relatively compact, which may allow the table to be stored in a smaller area. In addition, when in this relatively compact position, the table 10 may be more efficiently shipped in smaller packaging.
In further detail, when storage of the table 10 is desired, the lower portion 18 of the frame 14 may be moved from the extended position shown in FIGS. 1-2 to the collapsed position shown in FIGS. 3-4, and then the table top 12 and the upper portion 16 of the frame may be moved from the extended position shown in FIGS. 3-4 to the collapsed position shown in FIGS. 5-9. When use of the table 10 is desired, the table top 12 and the upper portion 16 of the frame 14 may be moved to back to their extended positions, and then the lower portion 18 of the frame may be moved back to its extended position.
In another instance, when storage of the table 10 is desired, the table top 12 and the upper portion 16 of the frame 14 may be moved from the extended position to the collapsed position, and then the lower portion 18 of the frame may be moved from the extended position to the collapsed position. In this instance, when use of the table 10 is desired, the lower portion 18 of the frame 14 may be moved to back to its extended position, and then the table top 12 and the upper portion 16 of the frame may be moved back to their extended positions. It will be appreciated that the various portions of the table 10 may be moved in different sequences and arrangements depending, for example, upon the size, shape, configuration and arrangement of the table.
To facilitate the movement of the table top 12 and the frame 14 between the extended and collapsed positions, the portions 16, 18, 20 of the frame may be pivotally or movably interconnected. For example, an upper part of the intermediate portion 20 may be pivotally or movably connected to the upper portion 16 of the frame 14, and a lower part of the intermediate portion may be pivotally or movably connected to the lower portion 18 of the frame. The portions 16, 18, 20 of the frame may be pivotally or movably interconnected using one or more brackets, connectors, fasteners, hinges, locking assemblies and/or any other suitable means and structures.
If desired, some or all of the components of the table top 12 and the frame 14 may be separately movable between the extended and collapsed positions. In addition, some or all of the components of the table top 12 and the frame 14 may be sized and configured to be collapsed before each other, after each other, or at the same time depending, for example, the particular configuration of the table 10. It will be appreciated that the components of the table top 12 and the frame 14 need not be separately movable between the extended and collapsed positions.
As shown in FIGS. 1-2, the table top 12 and the upper and lower portions 16, 18 of the frame 14 may be aligned in generally parallel planes when the table top and the frame are in the extended positions. In addition, when the table top and the frame are in the extended positions, the intermediate portion 20 may be in a generally perpendicular orientation relative to the table top 12 and/or the upper and lower portions 16, 18 of the frame 14.
As shown in FIGS. 5-9, the table top 12 and the upper, lower and intermediate portions 16, 18, 20 of the frame 14 may be aligned in generally parallel planes when the table top and the frame are in the collapsed positions. This may advantageously allow the table 10 to be stored in a smaller area and/or to be more efficiently shipped in smaller packaging. It will be appreciated, however, that the table top 12 and the upper, lower and intermediate portions 16, 18, 20 of the frame 14 may be disposed in other suitable relative positions when the table top and the frame are in the collapsed positions.
Desirably, some or all of the components of the table top 12 and the frame 14 may be locked in the extended and/or collapsed positions. For example, as shown in FIG. 2, the table 10 may include a first locking assembly 22 and a second locking assembly 24. The first locking assembly 22 may be sized and configured to lock the table top 12 and the upper portion 16 of the frame 14 in the extended positions, and the second locking assembly 24 may be sized and configured to lock the lower portion 18 of the frame in the extended position. The locking assemblies 22, 24 are preferably sized and configured to automatically lock the table top 12 and upper and lower portions 16, 18 in the extended positions. The locking assemblies 22, 24 may include triggers 26, 28, respectively, (such as a button, lever, handle, or the like) that may be used to unlock the locking assemblies to permit the table top 12 and/or upper and lower portions 16, 18 to be moved. It will be appreciated, however, that the locking assemblies 22, 24 need not be automatically lockable and that the triggers 26, 28 may be used to manually lock the locking assemblies. It will also be appreciated, that the table 10 does not require any locking assemblies 22, 24.
The table 10 may also include wheels 30, 32, 34, 36, which may be sized and configured allow the table to be quickly and easily moved to a desired location. The wheels 30, 32, 34, 36 may be sized and configured to engage a support surface, such as the ground or floor, when the table 10 is in an extended or use position, as shown in FIGS. 1-2. In addition, when the table 10 is in a collapsed or storage position, the wheels 30, 32 may engage the support surface while the wheels 34, 36 are spaced apart from and/or disengage the support surface, such as shown in FIGS. 5-9. However, the wheels 30, 32 may be spaced apart from and/or disengage the support surface when the table 10 is in the extended or use position or when the table is in the collapsed or storage position depending, for example, upon the particular configuration and/or intended use of the table 10.
The wheels 30, 32, 34, 36 may be connected to various portions of the frame 14. For example, the wheels may be connected to the lower portion 18 of the frame and/or the intermediate portion 20 of the frame. The wheels 30, 32, 34, 36 may also be connected to other suitable portions of the table 10. It will be appreciated, however, that the table 10 does not require any wheels.
As shown in FIGS. 10-11, the height of the table 10 may be adjustable. In particular, the height of the table top 12 may be movable between a plurality of heights. For example, the table top 12 may be sized and configured to move between a first position in which the table top is positioned for use at a first height and a second position in which the table top is positioned for use at a second height. It will be understood that the table 10 and table top 12 may be positioned at any desired height.
In further detail, the intermediate portion 20 of the frame 14 may include a height adjustment mechanism that is sized and configured to adjust the height of the table top 12. In particular, the height adjustment mechanism may increase or decrease the length of the intermediate portion 20 to raise or lower the table top 12. The height adjustment mechanism may advantageously be sized and configured to adjust the height of the table top 12 in a generally smooth fashion. For example, the height adjustment mechanism may include a spring (such as a gas spring, a coiled spring or the like) which may advantageously help adjust the length of the intermediate portion 20 in a generally smooth fashion. It will be appreciated that the height of the table top 12 may also be adjusted using other processes and structures, that the height of the table top toes not have to be adjusted in a generally smooth fashion.
The height adjustment mechanism may be sized and configured to be operated with one foot or one hand. For example, the height adjustment mechanism may include a trigger (such as a foot pedal) that may be operated with a foot to lock and/or unlock the table top 12 at a height. Also, for example, height adjustment mechanism may include a trigger (such as a button, lever, handle or the like) that may be operated with one hand to lock and/or unlock the table top at a height. In addition, the hand-operated trigger may be sized and configured to be grasped in order to help lift or lower the table top.
As shown in FIG. 1, the height adjustment mechanism may include a push button 38. The push button 38 may engage any plurality of openings 40 to help lock the table top 12 at a desired height. It will be appreciated, however, that the height adjustment mechanism does not require push buttons 38, openings 40, triggers or springs and that the height adjustment mechanism may include a variety of other suitable structures with appropriate components. It will also be appreciated that the table 10 does not require a height adjustment mechanism.
As shown in FIGS. 1-2, the table top 12 may include a plurality of table top sections, such as a first table top section 42 and a second table top section 44. The second table top section 44 may be sized and configured to rotate, pivot, tilt and/or move relative to the first table top section 42. Preferably, the first and second table top sections 42, 44 are movable when the table top 12 is in the extended or use position, but the table top sections could also be movable when the table top is in the collapsed position.
Advantageously, the movable table top sections may allow the table 10 to be used for a number of different functions and uses. In addition, the movable table top sections may accommodate a variety of users. The table top sections may also be movable between a number of different configurations and arrangements. Further, one or more of the table top sections may be movable and the different sections of the table top may be movable in the same or different directions.
For example, as shown in the accompanying figures, the second table top section 44 may be sized and configured to rotate, pivot, tilt and/or move between a first position in which the first and second table top sections 42, 44 are generally aligned (as shown in FIGS. 1-2) and a second position in which the second table top section is positioned at an angle relative to the first table top section (as shown in FIGS. 12-14 and in FIGS. 15-17). Advantageously, when the second table top section 44 is in the second position, the table top sections 42, 44 may be positioned for different uses. For example, the first table top section 42 could be positioned in a generally level or horizontal position to hold pencils, pens, rulers, books and the like. On the other hand, the second table top section 44 could be positioned at an angle, for example, to support a laptop computer in an ergonomically beneficial position. Of course, the table top sections 42, 44 may be positioned in other positions and may be used for other suitable purposes.
The table top section 44 may be sized and configured to rotate, pivot, tilt and/or move within a limited range of angles relative to the table top section 42. Limiting the movement of the table top section 44 relative to the table top section 42 may advantageously help to ensure the table top section 44 provides a working surface that accommodates intended uses. For example, as shown in FIGS. 14 and 17, the movement of the table top section 44 is preferably limited to an angle A of about fifteen degrees relative to the table top section 42, which may help the table top section 44 support a laptop computer while advantageously providing various ergonomically beneficial positions for the laptop.
If desired, the movement of the table top sections 42, 44 may be limited. For example, the movement of the second table top section 44 may be limited to an angle A of about ten, fifteen, twenty, twenty-five, thirty degrees or more relative to the first table top section 42 depending, for example, upon the particular intended use of the second table top section. Thus, where one or more of the table top sections are sized and configured to rotate, pivot, tilt and/or move, the movement of the table top sections may be limited to a specific range, which may be dependent upon the intended use of the table 10. Thus, it will be appreciated that the range of movement of the table sections may be larger or smaller than ten or thirty degrees. Therefore, for example, it will be appreciated that the movement of the second table top section 44 relative to the first table top section 42 need not be limited to about fifteen degrees or any other angle. It will also be appreciated that the second table top section 44 may be positioned at greater or lesser angles relative to the table top section 42, if desired.
The frame 14 may be sized and configured to facilitate the movement of the second table top section 44 relative to the first table top section 42. For example, the upper portion 16 of the frame 14 may include supports, such as brackets, tubes, rods and/or other supports. The supports may be connected to the table top sections 42, 44 and the supports may be movable relative to each other to facilitate the movement of the second table top section 44 relative to the first table top section 42. In further detail, as shown in FIGS. 18-19, the upper portion 16 of the frame 14 may include a first set of supports 46, 48 and a second set of supports 50, 52, and the first and second sets of supports may be connected to the first and second table top sections 42, 44, respectively. The upper portion 16 of the frame 14 may also include a pivot 54, which may be constructed from a tube, rod or the like, and the pivot may have an elongated configuration. The second table top section 44 and the supports 50, 52 may be pivotally, rotatably and/or movably connected to the pivot 54, which may allow the second table top section 44 and the supports 50, 52 to pivot, rotate, tilt and/or move relative to the first table top section 42 and the supports 46, 48. It will be appreciated, however, that the frame 14 does not require the supports 46, 48, 50, 52 or the pivot 54 and that the frame may include a variety of other components with different configurations that may be used to facilitate the movement of the second table top section 44 relative to the first table top section 42.
As discussed above, the movement of the second table top section 44 relative to the first table top section 42 may be limited. For example, as shown in FIGS. 20-23, the table 10 may include a locking assembly 55 that may be sized and configured to secure the first and second table top sections 42, 44 in desired positions and/or to limit the movement of the first and/or second table top sections. In particular, the locking assembly 55 may include a flange 56 and a pin 58. The flange 56 may be sized and configured to engage the pin 58 to secure the table top section 44 in a desired position relative to the table top section 42. In addition, the flange 56 may be sized and configured to engage the pin 58 to limit the movement of the table top section 44 to a limited range of angles relative to the table top section 42.
In further detail, the flange 56 may include a plurality of receiving portions 60 that are sized and configured to engage the pin 58 using, for example, a snap fit, a friction fit and/or an interference fit. This may advantageously limit the relative movement of the flange 56 and the pin 58. More significantly, this may limit the relative movement of the table top sections 42, 44 because the flange 56 may be secured to table top section 42 and the pin 58 may be secured to the table top section 44. For example, the flange 56 may be connected to the pivot 54, which may be connected to the table top section 42 by the brackets 46, 48; and the pin 58 may be connected to a handle 62, which may be connected to the table top section 44.
The handle 62 may be used to move the pin 58 among a variety of positions to help facilitate the movement of the table top section 44 from a first position relative to the table top section 42 to a second position relative to the table top section 42. In particular, the pin 58 may initially engage a first receiving portion 60, which may lock the table top section 44 in the first position. When it is desired to move the table top section 44, the handle 62 may be used to pull the pin 58 in a direction away from the flange 56, causing the pin to disengage the first receiving portion 60. When the pin 58 is disengaged from the first receiving portion 60, the table top section 44 may be pivoted, rotated, tilted and/or moved from the first position to the second position. With the table top section 44 in the second position, the handle 62 may be used to push the pin 58 in a direction towards the flange 56, causing the pin to engage a second receiving portion 60 to generally lock the table top section 44 at the second position.
As shown in FIG. 19, the locking assembly 55 may include a biasing member 64, such as a spring. The biasing member 64 may be sized and configured to bias the pin 58 in a direction towards a locked position in which the pin engages the flange 56 and away from an unlocked position in which the pin is disengaged from the flange. In particular, the biasing member 64 may be sized and configured to bias the handle 62 in a direction towards the flange 56 and, thus, to bias the pin 58 in a direction towards a locked position in which the pin engages one of the receiving portions 60. For example, the biasing member 64 may be sandwiched between a portion of the handle 62 and a portion of the table top section 44. When the handle 62 pulls the pin 58 away from a locked position to an unlocked position, the biasing member 64 may be compressed between the portions of the handle and the table top section 44. When the handle 62 is released, the biasing member 64 may bias the pin 58 into the locked position.
As shown in FIGS. 21-23, the receiving portions 60 may be formed as part of a single, unitary opening or recess 66. This may allow the pin 58 to move among the various receiving portions 60, while at least a portion of the pin remains in the opening 66. In particular, the opening 66 may include narrowed passageways 68 that join adjacent receiving portions 60. Desirably, the pin 58 may be sized and configured to pass through the narrowed passageways 68 when the pin is in an unlocked position. For example, an end 70 of the pin 58 may have a generally tapered configuration and a narrower portion of the generally tapered end may be sized and configured to pass through a narrowed passageway when the pin is in an unlocked position. This may allow a portion of the pin 58 to remain in the opening 66 while the positioning of the second table top section 44 is being adjusted.
Because the pin 58 may remain in the opening 66, the pin may eventually contact, abut and/or engage the ends 72, 74 of the opening when the second table top section 44 reaches a particular position relative to the table top section 42. Advantageously, this may prevent the second table top section 44 from moving past those particular positions. For example, as shown in FIG. 22, the pin 58 may contact, abut and/or engage the end 72 of the opening 66 when the table top section 44 reaches the position shown in FIG. 12. Likewise, as shown in FIG. 23, the pin 58 may contact, abut and/or engage the end 74 when the table top section 44 reaches the position shown in FIG. 15. Thus, the opening may advantageously be sized and configured to limit the movement of the second table top section 44 to a limited range of movement relative to the first table top section 42, as discussed above. It will be appreciated, however, that the receiving portions 60 need not be formed as part of a single, unitary opening or recess and that some or all of the receiving portions may be formed as discrete openings, recesses and/or other suitable features, if desired.
As discussed above, the table top section 44 may be locked and unlocked in various positions without the tightening and loosening of a knob or fastener. In particular, the locking assembly 55 and/or other components of the table 10 may form a friction fit, an interference fit and/or a snap fit that is sized and configured to allow the position of the table top section 44 to be incrementally adjusted without having to tighten and/or loosen a knob or fastener. It will be appreciated, however, that the table 10 may include in other features that may allow the table top section 44 may be locked and unlocked in various positions without the tightening and loosening of a knob or fastener. For example, the table 10 may include a ratcheting mechanism that is sized and configured to allow the position of the table top section 44 to be incrementally adjusted without having to tighten and/or loosen a knob or fastener. It will be appreciated, however, that the tightening and loosening of a knob or fastener may be used to lock and unlock the table top section 44, if desired.
As shown in FIGS. 28-29, an exemplary wheel assembly 76 may include a first wheel section 78, a second wheel section 80 and a hub 82. The first wheel section 78 may include an opening 84 through which a support member 86, such as an axle, may extend. With the support member 86 extending through the opening 84 in the first wheel section 78, the hub 82 may be connected to the support member using one fasteners 88 and then the wheel sections 80, 82 may be interconnected using fasteners 90.
Desirably, the wheel sections 78, 80 and the hub 82 may be connected to an end the support member 86, which may eliminate any need for a cap or cover for the end of the support member 86. It will be appreciated, however, that the hub 82 may be connected to other portions of the support member 86. It will also be appreciated that the wheel sections 80, 82 and/or the hub 82 and the support member 86 may be interconnected using any suitable number and arrangement of fasteners or other suitable fasteners. It will further be appreciated that the wheel sections 80, 82 and the hub 82 may be connected using a snap fit, a friction fit, and/or an interference fit; one or more adhesives and/or other suitable means.
As shown in FIG. 28, one or both of the wheel sections 78, 80 may form at least a part of a receiving portion 92, which may receive at least a portion of the hub 82. In particular, the receiving portion 92 may be sized and configured to receive and rotatably couple a ridge 94 formed in the hub 82, which may allow the wheel sections 78, 80 to rotate about the hub. In addition, the ridge 94 may be positioned between the wheel sections 78, 80, which may desirably limit the movement of the wheel sections along the length of the support member 86.
As shown in FIG. 29, the hub 82 may include a receiving portion 96 that may be sized and configured to receive and/or retain at least a portion of the support member 86. In particular, the support member 86 may have a non-circular cross section and the receiving portion 96 of the hub 82 may have a complementary non-circular cross section that is sized and configured to engage the support member using a snap fit, a friction fit and/or an interference fit. For example, the support member 86 may have a generally oblong configuration and the receiving portion 96 of the hub 82 may have a generally oblong configuration. Desirably, this may help prevent the hub 82 from rotating relative to the support member 86. Moreover, this may allow the wheel assembly 76 to be used in connection with a generally oblong support member 86. It will be appreciated, however, that the support member 86 and the receiving portion 96 may have any other suitable shape and/or configuration.
As shown in FIG. 28, the support member 86 may be connected to a pin 98. The pin 98 may extend through an opening 100 in the hub 82 and into a receiving portion 102 formed in the wheel section 80. Desirably, the pin 98 may help provide additional support for the hub 82 and/or the wheel section 80.
As best seen in FIGS. 1-2, the wheel sections 78, 80 may help hide the attachment of the hub 82 to the support member 86. This may advantageously help provide a cleaner, more appealing visual appearance.
Although this invention has been described in terms of certain preferred embodiments, other embodiments apparent to those of ordinary skill in the art are also within the scope of this invention. Accordingly, the scope of the invention is intended to be defined only by the claims which follow.
