Patent number: 11903465Abstract: An umbrella includes an anti-inversion mechanism that is configured to apply to each rib assembly a force that counters an inversion force that is applied to the umbrella. The anti-inversion mechanism includes a first rib joint that is coupled to first and second ribs, a first elongated member that is coupled to the first rib joint and a second elongated member that is coupled to the first elongated member and to the distal rib. The first rib joint includes an inner slot and the first elongated member comprises a wire having a bent clip portion at a first end of the wire, the bent clip portion being received within the inner slot and being biased against a floor of the inner slot resulting in the wire being attached to the first rib joint.Type: GrantFiled: November 3, 2021Date of Patent: February 20, 2024Assignee: SHEDRAIN CORPORATIONInventor: David Haythornthwaite

Publication number: 20210378372Abstract: An umbrella includes an anti-inversion mechanism that is configured to apply to each rib assembly a force that counters an inversion force that is applied to the umbrella. The anti-inversion mechanism includes a flexible elongated structure that is disposed exteriorly along the second rib part and has a first bent end that is attached to the second rib part by passing through an opening formed in the second rib part and being anchored within a hollow interior of the second rib part. The mechanism further includes a flexible wire having a first end attached to the flexible elongated structure of the anti-inversion mechanism and a second end attached to a rib tip that is located at a free distal end of the rib assembly.Type: ApplicationFiled: October 24, 2019Publication date: December 9, 2021Inventor: David Haythornthwaite

Patent number: 10743627Abstract: An umbrella has a plurality of ribs attached to a runner by main struts. The umbrella has an anti-inversion mechanism formed of a plurality of anti-inversion struts. Each anti-inversion strut is pivotally coupled to one respective main strut and is pivotally connected to a floating joint member that is freely movable along a length of one respective rib. The anti-inversion mechanism also includes a stop that is fixedly attached to the rib and restricts the degree of travel of the floating joint member along the rib and is positioned to prevent the respective rib from inverting in response to an applied force.Type: GrantFiled: September 10, 2018Date of Patent: August 18, 2020Assignee: SHEDRAIN CORPORATIONInventors: David Haythornthwaite, Andrew Haythornthwaite

Patent number: 10238214Abstract: A backpack type folding chair is provided and includes a chair frame including a seat frame, a back frame, a front leg frame, and a back leg frame. At least one support panel to support a user is coupled about the back frame and the seat frame. A first storage receptacle is coupled to a rear face of a backrest portion of the at least one support panel that is coupled to the back frame. In addition, a second storage receptacle is defined between the first storage receptacle and the backrest portion. A pair of detachable shoulder straps are provided with each strap includes a first end that is attached along the rear face of the backrest portion and a second end that includes a first fastener that is configured to mate with a coupling member that is attached to the at least one support panel proximate the cross member for attaching the second end of the shoulder strap to the chair and permit carrying of the chair in a folded position.Type: GrantFiled: October 24, 2017Date of Patent: March 26, 2019Assignee: SHEDRAIN CORPORATIONInventor: David Haythornthwaite

Patent number: 9756912Abstract: A wind resistant umbrella includes an upper canopy that is attached to a lower canopy at select points. Elastic fasteners (e.g., elastic straps) elastically connect the upper canopy to the lower canopy. Flexible connectors that wrap around a peripheral edge of the lower canopy serve to both fixedly attach first ends of the elastic fasteners and provide pockets that receive free ends of the ribs to securely attach the ribs to the lower canopy.Type: GrantFiled: February 24, 2016Date of Patent: September 12, 2017Assignee: SHEDRAIN CORPORATIONInventor: David Haythornthwaite
