Abstract: A design for a universal telescoping swing gate can be sized to obscure a wide range of openings while accommodating a multitude of installation options to make the gate versatile under many conditions. The swing gate can have a frame with a pivot member rotatable about a mounting seat between an open configuration and a closed configuration. The frame can have first and second telescoping members adjustable along an extension axis between a collapsed state and a fully extended state for changing the frame length so the gate can be quickly furnished to different sized openings. The gate can be spring loaded to bias the frame to a nominally closed position to reduce the chance for human error among workers. The gate can also be sized to have the structural rigidity to comply with OSHA requirements for handrails and guardrails around a walking-working surface.

Abstract: A telescopic cover which relieves impact caused when a cover member is stopped moving and which is less meandering. A braking mechanism is provided between one of two adjacent cover members of the telescopic cover and the other of the two adjacent cover members which telescopically moves into and out of the one cover member. The braking mechanism is provided at a distal end portion of the one cover member, and has an elastic member that presses a slide member against the other cover member.

Abstract: A machine tool way cover to provide protection to a moveable machine tool which is provided with an interlocking feature to prevent misalignment or skewing of the actual way cover. The present invention provides a dramatic improvement over prior art machine tool coverings and way covers in that it eliminates the need for individual segments of the machine tool way cover to be manufactured to extremely tight physical tolerances by providing interlocking channels at the base of each way cover segment. The channels provide grooves within which the channels of smaller segments actually move as the machine tool and machine tool way cover move in and out. By providing such an interlocking mechanism, the machine tool way cover avoids becoming misaligned and inoperative even when objects or personnel impart substantial loads to the way cover.
