Abstract: A mattress retention assembly is disclosed that includes a mattress retainer system for retaining a mattress in place that is supported by an adjustable platform assembly and more particularly to a mattress retainer system that includes mattress retainer bars. The mattress retainer system is attached to the adjustable platform assembly. In order to secure the mattress relative to the adjustable platform assembly, one or more mattress retainer bars for the head and foot of the bed along with the corners of the bed are provided. In accordance with an important aspect of the invention, the mattress retainer bars are movable or removable to allow the mattress retainer bars to be positioned flush or below the top surface of the adjustable platform assembly to enable easy and convenient rotation, maneuverability, or otherwise sliding of the mattress relative to the platform.

Abstract: A metal element which includes a surface, a first end portion and an opposite, second, end portion, the first end portion being formed with a plurality of inner cuts designed so as to enable a plurality of pieces each remaining integrally connected to the metal element to at least slightly protrude from the surface, each of the pieces featuring at least one sharp or pointed edge generally pointing towards the opposite, second end portion.

Abstract: A flexible coupling device including a flexible metal rod or wire within a flexible tube which can be removably secured through the aligned bores of the pieces. The pieces are held in a fixed longitudinal relationship using the axial tension created by the flexible coupling device while still permitting relative rotation between each of the pieces. The flexible metal rod or wire is secured through various mechanism which include radial angular ridges in the interior of the flexible tube and a retaining post having radial angular ridges that interlock with the ridges in the flexible tube such that, as the post is inserted into the flexible tube, the post ridges and the tube ridges interlock to secure the flexible tube. In addition, radial angular ridges on the exterior of the flexible rod interlock with a retaining post having an interior bore with corresponding radial angular ridges as the flexible rod is inserted into the retaining post.

Abstract: A manual support apparatus attachable to a bedframe. The manual support device includes a support tube having at least two legs, and at least two fastening members which are adapted for attachment to the bedframe. The fastening members are secured to the support tube legs. In another embodiment, the manual support apparatus includes a support tube without separate leg portions, wherein the fastening members are secured to support tube body. At least two means for attaching the fastening members to the bedframe are provided. The support tube is shaped to conform to at least one corner of the bedframe. The apparatus provides a secure and stable method for a user/patient to transfer into and out of bed, particularly hospital beds, independently and enhance in-bed mobility.

Abstract: A method of assemblying a hammer from a handle, a wedge unit and a hammer head unit. The handle has a top end having a neck portion that has a pair of vertical slots that intersect each other at substantially 90 degrees to each other. The wedge unit is formed from an x-axis wedge and a z-axis wedge section that are oriented to each other at substantially 90 degrees. The hammer head unit has a hammer portion a central portion and a claw portion. The central portion has a bore hole that extends from its top surface to its bottom surface. An arbor press is used to press the wedge section into the grooves on the top end of the handle.

Abstract: A locking sleeve (14) for holding the tensioned, internal elastic cord (22) of a compactable, collapsible tubular assembly (12-10) comprises a resilient member (14), in the shape of a slit tube. It is held in position within the tubular insert of the compactable, tubular assemblies by external barbs (16). The elastic cord is in turn held in position within the locking sleeve by an internal tongue (20) and prongs (18).

Abstract: An end connector for attachment to a tubing end including a housing having a first aperture therethrough with a predetermined internal periphery and a plug member having a predetermined external periphery for cooperative engagement with the end of the tubing and the internal periphery of the first aperture of the housing, the plug member releasably retaining a portion of the end of the tubing between the external periphery of the plug member and the internal periphery of the first aperture of the housing to prevent removal of the tubing from the housing when the tubing is subjected to tension in a desired direction.

Abstract: An arrangement for interconnecting and supporting a pair of hexagonal building structures includes a pair of common support columns each having a hexagonal shaped connector tube mounted to an upper end thereof. Each connector tube includes apertures in each of the six lateral walls thereof which are adapted for receiving a nut and bolt combination for coupling the tube to the eave beams and roof trusses of two hexagonal building structures. The nut and bolt combinations are hidden from view within the connector tube and adjacent beams to provide a clean, attractive appearance and are not exposed to the elements. The use of common support columns and a common eave beam for adjacent hexagonal building structures simplifies assembly, reduces the number of structural components and building cost, and integrates two or more of such building structure for increased structural strength.

Abstract: A handle bracket retainer for retaining a handle to the socket of a plastic shovel, snow pusher, and the like without the need of the screws. The handle bracket retainer includes tapered body having a nearly semi-circular cross-section with opposed edges being tapered from end to end. A plurality of tabs and prongs permit a wooden handle to be retained in the socket of plastic tool.

Abstract: A cylindrical wedge for holding a tool head on a wooden tool handle has a tapered exterior surface and a central bore containing a throat section that is dimensionally smaller than the openings at either end of the bore. When the wedge is embedded in a wooden handle, the tapered exterior surface spreads the handle within the eye of the tool, and the throat section grips the handle core to hold the wedge securely in the handle.

Abstract: A wedge for securing a wooden handle to the head of a tool, the wedge having serrated tapered surfaces and serrated tapered edges and being bent into a U-shape. The wedge has a bight portion laying adjacent the end of the oval-shaped eye of the tool, and has arms lying parallel to the major axis of the oval-shaped eye of the tool.
