Description
TITLE
ERGONOMIC, HEIGHT ADJUSTABLE WORK SURFACE
FIELD
Height Adjustable Work Surfaces.
BACKGROUND
Height adjustable work surfaces are well known, and commonly used in the context of providing a surface for ironing clothes. Existing height adjustable work surfaces typically feature legs which are cross-connected with each other, forming a folding structure.
Height adjustable work surfaces can also be used for studying or working on projects and crafts. Adjustment of the height of a work surface at frequent intervals so as to alternate between sitting and standing positions may be desirable. As well, persons of varying heights may wish to use the same work surface. Accordingly, the mechanism for raising and lowering a height adjustable work surface should be designed so that height adjustments are completed quickly and easily.
Transporting height adjustable work surfaces to multiple locations completing different tasks may be desirable. Accordingly, height adjustable work surfaces should be designed so that transportation is convenient and comfortable.
Existing height adjustable work surfaces can require the performance of multiple actions in order to complete an adjustment of the work surface height, or to collapse the work surface completely. The task of completing of adjustments to the height of the work surface can interrupt work processes being performed. It is desirable that interruptions to other work processes be short in duration. Accordingly, the mechanism for raising and lowering a height-adjustable work surface should be designed so that adjustments are simple and require little time to complete.

Accordingly, the mechanism for raising and lowering a height-adjustable work surface should be designed so that adjustments are simple and require little time to complete.
2 Manually raising and lowering existing height adjustable work surfaces requires the application of physical effort that is proportional to the size and weight of the work surface. Multiple adjustments to the height of a work surface may become difficult for some people due to the amount of physical effort necessary. Accordingly, the mechanism for raising and lowering a height adjustable work surface should be designed so that the amount of physical effort required to adjust the height of the work surface is minimized and comfortable.
SUMMARY
There is provided a work surface of adjustable height that is adapted to be collapsed during storage and transportation comprising a table member of predetermined length and width having an upper and a lower surface, means for adjusting the height of said table attached to said lower surface and longitudinal support means. The support means includes two leg members which are cross-connected with each other, forming a folding structure. Leg members are hollow, rectangular, and have a transverse hollow tubular foot member attached to both ends of said leg members. It is desirable for stability purposes that the foot members be equivalent in length to the width of the table member. The juncture where the leg members are cross-connected is located one third of the distance of the length of the leg members from the upper foot members.
Typically, work surfaces of this field will have one of said leg members pivotally attached to said lower surface of table, with the other being pivotally attached to a sliding rail mechanism for adjusting height which is attached to said lower surface of table. Said mechanism will typically include of a friction lock which is releasable by a lever attached to the lower surface of the table. Conventional work surfaces are adjusted for height by grasping the both sides of the width of the table and lifting or lowering the table top manually. The friction lock lever is released when the table is at the desired height.
In the present invention, the upper foot member of one leg member is pivotally attached to the lower surface of the table. The other leg member is not attached to the lower

Leg members are hollow, rectangular, and have a transverse hollow tubular foot member attached to both ends of said leg members. It is desirable for stability purposes that the foot members be equivalent in length to the width of the table member. The juncture where the leg members are cross-connected is located one third of the distance of the length of the leg members from the upper foot members.
Typically, work surfaces of this field will have one of said leg members pivotally attached to said lower surface of table, with the other being pivotally attached to a sliding rail mechanism for adjusting height which is attached to said lower surface of table. Said mechanism will typically include of a friction lock which is releasable by a lever attached to the lower surface of the table. Conventional work surfaces are adjusted for height by grasping the both sides of the width of the table and lifting or lowering the table top manually. The friction lock lever is released when the table is at the desired height.
In the present invention, the upper foot member of one leg member is pivotally attached to the lower surface of the table. The other leg member is not attached to the lower
3 surface of table, allowing said table to rotate on the axis of that foot member which is attached the lower surface of table. The present invention does not include a sliding rail mechanism or friction lock lever.
A horizontally oriented handle will be attached or incorporated into the end of the table opposite that end of the table to which the attached leg member is located. The handle will be positioned in the middle of the width of the work surface.
A horizontally oriented handle will be attached or incorporated into the side of the table. The handle will be positioned along the length of the work surface, one third of the length of the table from that end to which the end handle is attached.
In its collapsed state, a foot member will protrude from beneath that end of the work surface where the end handle is located. Prior to raising the work surface from its collapsed position, the person performing the adjustment will position his or her self at the end of the table where the handle is located and brace against the floor with his or her foot, that lower foot member which is located at the same end as the handle. The work surface is then raised by grasping the handle and lifting this end of the table to a diagonal position and pulling the table inward.
Pulling the lifted end of the table inward will elevate the table in a diagonal motion and force the attached leg member to pivot at the foot member that is attached to the lower surface of the table. The attached leg member will also pivot on the floor at the point where it has been braced by the person raising the table. As the table is pulled upward, the attached leg member is raised. As the leg member that is attached to the table is raised, that leg member that is connected to the attached leg is also raised at the point of their juncture.
The leg member that is connected to the attached leg will pivot freely at the point of their juncture, with its lower foot member resting on the floor while its upper foot member rises to a height which corresponds to the height of that upper foot member which is attached to the lower surface of the table.
A horizontally oriented handle will be attached or incorporated into the end of the table opposite that end of the table to which the attached leg member is located. The handle will be positioned in the middle of the width of the work surface.
A horizontally oriented handle will be attached or incorporated into the side of the table. The handle will be positioned along the length of the work surface, one third of the length of the table from that end to which the end handle is attached.

Prior to raising the work surface from its collapsed position, the person performing the adjustment will position his or her self at the end of the table where the handle is located and brace against the floor with his or her foot, that lower foot member which is located at the same end as the handle. The work surface is then raised by grasping the handle and lifting this end of the table to a diagonal position and pulling the table inward.
Pulling the lifted end of the table inward will elevate the table in a diagonal motion and force the attached leg member to pivot at the foot member that is attached to the lower surface of the table. The attached leg member will also pivot on the floor at the point where it has been braced by the person raising the table. As the table is pulled upward, the attached leg member is raised. As the leg member that is attached to the table is raised, that leg member that is connected to the attached leg is also raised at the point of their juncture.
The leg member that is connected to the attached leg will pivot freely at the point of their juncture, with its lower foot member resting on the floor while its upper foot member rises to a height which corresponds to the height of that upper foot member which is attached to the lower surface of the table.
4 Adjustments to the height of the work surface are secured by lowering that end of the table to which the handle is attached onto the upper foot of the unattached leg member, when said foot member is at the desired height. The lower surface of the left side of the table includes two corresponding rows of attached catches which are spaced at equivalent intervals. The placement of said catches will cause the upper foot of the unattached leg member to rest against the lower surface of the table.
Prior to lowering the work surface to a collapsed position, the person performing the adjustment will position his or her self at the end of the table where the handle is located and brace against the floor with his or her foot, that lower foot member which is located at the same end as the handle. The person will grasp the handle and pull inward so that the catches attached to the lower surface of the table are not in contact with the upper foot member. The end of the table is lifted to a diagonal position. The person will lower the work surface by extending that arm which is grasping the handle in a diagonal and downward direction towards the floor. As the table is lowered, the leg members will fold at their juncture. As the leg members fold, their respective foot members will extend horizontally outward. The lowered table will rest directly on top of the folded leg members.
Prior to transporting the work surface, it is lowered to a collapsed position.
While it is in a collapsed state, the leg members are secured to the lower surface of the table by two adjustable catches. The work surface is then lifted onto its side using the attached handle. The work surface is transported by further lifting the table off of the floor, allowing it to be carried to a desired location.
