Height-adjustable sewing table

Abstract

A height-adjustable sewing table, having a flat tabletop providing a work surface for piece goods and craft items being sewn. The tabletop is supported by a pair of height-adjustable leg assemblies, having a base, a tubular column and an extendible member with one ends which registers with the tubular column. The other end of the extendible member engages and articulates with the undersurface of the tabletop. An opening is provided in the tabletop, into which a sewing machine mounted on a platform is raised from or lowered into a position from below the tabletop by a lifting mechanism. The lifting mechanism preferably has mast mounted vertically and a carriage which rides vertically along the mast. The platform is mounted on the carriage. The carriage may be moved manually or with pneumatic or electrical power assistance. Likewise, the extendible members of the leg assemblies may be extended manually or with pneumatic or electrical power assistance.

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority under 35 U.S.C. §119(e) from U.S. Provisional Application No. 60 / 709,144, filed under 35 U.S.C. 111(b) on Aug. 16, 2005, entitled “Height-Adjustable Sewing Table”.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to tables for supporting sewing machines. [0004] 2. Description of the Prior Art [0005] Sewing machines are a common type of machinery used in the garment industry and by individuals for arts, crafts and creating and repairing garments. [0006] Sewing machines owned by individuals may be portable. A portable machine is stored in a case kept in a storage location, such as a closet, when not in use. It is then set up on a table or other work surface when placed into operation. When the sewing operations are complete, the machine is returned to its case and the case returned to its storage location. [0007] Sewing machines may also be installed essentia...

AI Technical Summary

Benefits of technology

[0016] The combination of height adjustments for both the sewing machine platform with respect to the work surface, as well as the work surface with respect to the operator, provides flexibility for accommodating the needs of nearly all sewing machine operators. The work surface can be adjusted to accommodate the comfort of all sewing machine operators, including those in wheel chairs, as well as those wishing to stand rather than sit before the sewing cabinet.

[0017] One embodiment of the invention includes a table top which can be tilted towards the operator, typically by about 5 degrees. This permits the operator's line of sight to be orthogonal to the work surface and directly above the sewing needle of the sewing machine, which facilitates more accurate seams, without having to uncomfortably bend over the work surface and sewing machine.

Problems solved by technology

One disadvantage typically found in these pivoting platform designs is a limitation to a single working height for the sewing machine.

This limitation may decrease the utility of the sewing machine mounted thereon.

However, the height of the work surface is typically not adjustable.

The fixed height of the work surface of the sewing cabinet is often inconvenient and uncomfortable for very short or very tall operators.

Sewing machine cabinets also do not usually accommodate special seating arrangements, such as wheelchairs.
