Appl. No.:

09/604201

Inventors:

Henry Wu - Diamond Bar CA 91765

International Classification:

A47C 424

US Classification:

297 56, 108118

Abstract:

A folding chair comprising a first and second safety brace member that provide the chair with additional structural integrity. The chair having a folded configuration and an unfolded configuration comprises first and second chair support members that are pivotally attached to each other so as to define a central pivot axis such that the chair is manipulated between the folded and unfolded configurations by tilting the first and second chair support members with respect to each other about the central pivot axis. The chair further comprises a seat which extends between the first and second chair support members such that the seat is aligned with the support members in the folded configuration and horizontally aligned in the unfolded configuration. Respective first and second ends of each brace member are slidably mounted to the first and second chair support members so that that they are able to accommodate tilting of the first and second chair support members of the chair between the folded and unfolded configurations. In the folded configuration, the brace members are aligned with the first and second chair support members of the folding chair so as to enable a plurality of such chairs to be stacked within a reduced space.

US Classification:

40320, 4060608, 40666

Abstract:

A sign holding device for a folding chair that allows the user to display customized messages on a back rest of the chair. The sign holder is attached to the back rest in various manners so as to permit messages to be displayed when the chair is unfolded. The sign holders are configured such that when the chair is folded, the chair can be carried and stacked without having to remove the sign holders from the back rest. One embodiment of the folding chair also includes an integral carrying handle that permits the folded chair to be carried by one hand. The integral carrying handle further comprises an opening that permits the carrying hand to grasp the handle better, and also permit the chair to be unfolded without removing the hand from the handle, such that the unfolding action does not pinch the carrying hand.

International Classification:

A61F009/00

US Classification:

606107000

Abstract:

Apparatus and method for implantation of intraocular lenses (IOLs) with various designs, particularly a full-size IOL, into the eye through small incisions are disclosed. A full-size intraocular lens mimics the natural human crystalline lens in size and volume. The SMART™ IOL, a full-size design, utilizes the thermodynamic properties of a crystalline polymeric material composition. The insertion apparatus and method of the present invention allow the full-size SMART™ IOL to be inserted through a small incision (about 4 mm or less) by deforming it with a crimping device into a solid rod and delivering the rod into the eye with a temperature-controlled injector equipped with a temperature control device. Once the solid rod is located in the desired position inside the eye, human body temperature softens the rod and allows it to reform back into the original lens geometry with defined optical properties.

International Classification:

US Classification:

297239

Abstract:

A plurality of stackable folding chairs having two sets of legs pivotally attached to each other and a seat pivotally attached thereto. Indentations are formed in a first side of one of the two sets of legs and a protrusion is formed on a second side of the legs at approximately the same location. The chairs are configured to be folded so as to be substantially planar in configuration with the indentations and the protrusions exposed. The protrusions of a first chair can then be positioned within the indentations of a second chair so that the first and second chairs are positioned adjacent each other in a stacked configuration. The indentations preferably have an outer region that has a greater cross sectional area than the protrusions thereby facilitating positioning of the protrusion within the indentations and a second inner region having a cross sectional area that is configured so that the protrusion is flushly positioned within the inner region to thereby substantially prevent relative movement between the first and second chairs when the first and second chairs are in the stacked configuration.

International Classification:

A47C 400

US Classification:

297 56

Abstract:

A folding chair containing a pair of safety guards that are adapted to provide additional structural support to the chair. Each safety guard is comprised of a first member and a second member that are pivotally attached to each other at a central pivot point. Each safety guard is configured with an orthogonally extending lip on the first member and a corresponding indentation on the second member that, when combined, limit the possible orientations between the two members to range from an overlapping state to a linearly extended state. Both ends of each safety guard are pivotally attached to the chair in a manner that results in the safety guards being linearly extended when the chair is converted to a fully opened position and nearly overlapping when the chair is converted to a folded position.
