Abstract: A pet bed that includes an enclosure having a perimeter wall and a floor, and a cushion. The cushion includes a pliable external shell that holds several helical springs, each helical spring being individually covered in a flexible bag. The shell and springs are in turn held within a pliable casing, so that the cushion nests within the perimeter wall, so that the cushion provides variable support to a pet on the cushion by allowing the individually covered springs to flex independently of one another.

Abstract: An all mechanical support surface that tracks the flotation properties of a true fluid and utilizes a series of constant restoring force springs connecting reciprocating pistons which have supporting surfaces with multiple degrees of freedom to define a user supporting surface that assumes the shape of the user and minimizes the force differential on different areas of the user's skin.

Abstract: The invention relates to a bearing element having a base plate fitted on a support, for a seat or bed system, with a bearing plate to hold upholstery. The invention seeks to produce a bearing element whose range of spring is approximately equal to the total height, and which is easy to produce. To this end, at least two spring elements serving as bearing arms (12, 22) are fitted between the base plate (11, 21) and the bearing plate (15, 25). These spring elements, configured like leaf springs, are directed outwards from the base plate (11, 21). Their outer ends join the hearing plate (15, 25). In another version of the invention, a spring body (35, 35′) is fitted between the base and bearing plate. The spring body head (35.2) and foot (35.1), like the bearing plate and base plate, have corresponding locking parts, so that the bearing plate can also be removably placed on the spring body (15, 15′) and on the base plate (21).

Abstract: A resin-made cushioning element 1 which is of one-piece construction includes upstanding and downstanding portions 2a and 2b alternately arranged in regular manner to form a matrix having four peripheries.

Abstract: The subject matter is a cushion core construction in which individual elements of cushion material in plug-like form are connected together in a string by capturing them between two strips of flexible sheet material which are joined together between adjacent elements to hold the elements in place. The preferred structural unit is a two-row module formed by joining two such strings at intervals of at least two elements to enable them to stand alone, and to facilitate their handling in their assembly with like modules to form a more extensive core.

Abstract: A mattress (10) with interactive elastic elements, comprising a number of hollow polyhedrons (11) with an octagonal base, made of an elastic and/or yielding material, arranged in longitudinal rows (12), interconnected and held in position within each row (12) by linings (30) made of a textile material enclosing the individual rows (12) of polyhedrons (11) or by guide bars (13) attaching to them by coupling devices (14) arranged on two lateral faces (15) opposing each other. Under the weight of an outstretched body (30) on the surface (21) of the mattress (10), each elastic polyhedron (11) compresses while bulging out transversally and exerting a pressure on the adjacent elastic elements (11), thus expanding them in length.

Abstract: The invention relates to a spring core for mattresses and seat cushions with leaf springs. The spring core consists of a plurality of spring elements bent up out of passages punched in a plate, with each spring element having an upper and a lower spring clip, with the upper spring clip bent up out of a passage punched in the lower spring clip. The spring elements can also be coated with extruded foam.

Abstract: High and low profile mattress foundation frames have perimeter and transverse members, and upper members to which spring modules are attached to support a grid over the frame, to form a flexible support surface for a mattress. In a high profile version of the frame, transverse members are oriented with a major width perpendicular to a major width of the perimeter members, to provide structural rigidity and increased height to the frame. Low profile spring modules, such as the described composite material spring modules, supported by the high profile frame form a foundation which is comparable in overall height to conventional mattress foundations which use wire-form spring modules. In a low profile version of the frame, the major widths of the perimeter and transverse members are arranged parallel, and longitudinal members are supported by the transverse members.

Abstract: Disclosed is a spring formed from a synthetic resin into one body, including: a plurality of annular members arranged in such a manner as to be coaxial with each other and spaced in parallel to each other; and elastic linkage members for linking the annular members to each other at a plurality of points. In the spring, each of the elastic linkage members is arranged along a virtual cylindrical face formed by the annular members and formed into a lying U-shape curved in the peripheral direction of the annular members; radii of adjacent ones of the annular members are different from each other; and one end portion and the other end portion of each of the elastic linkage members, which portions are respectively linked to the adjacent ones of the annular members, are not overlapped to each other in the axial direction.

Abstract: A novel pillow core is made of plastic springs. A plurality of springs are connected together by a plastic link frame to form an actual pillow shape. The pillow core made of the plastic springs has strong supporting capacity, good elasticity and ventilation, and eliminates areas of heat concentration. It can easily be made into different sizes and can accommodate the neck portions of different users. In addition, it is easy to carry about and eliminate the necessity for cleaning and drying. Moreover, it saves raw materials such as feathers or silk cotton and the like, and shows excellent quality with reasonable prices.

Abstract: A rubber pad construction is adapted for use in making a shoe sole, a shoe pad, a face layer of a table-tennis paddle, a shell of a ball, etc. The rubber pad construction includes a substrate, and a plurality of first and second protrusions which extend outwardly from one side of the substrate at intervals. The first protrusions are thinner and higher than the second protrusions to provide more flexibility. The second protrusions have more bearing ability than the first protrusions. The rubber pad construction provides desirable shock-absorbing and rebounding qualities.

Abstract: A cushioning support for a mattress comprises a plurality of elements forming a grid structure. Compression springs are mounted on respective ones of the elements. Bearing plates are disposed atop respective ones of the springs, and are disposed closely adjacent one another to form together a support surface for the mattress. The baseplates are removably interconnected so that the size and shape of the cushioning support can be varied to conform to the size and shape of a cushion to be supported. The springs can be detachably connected to the elements, or of one piece construction therewith.

Abstract: A formed wire spring assembly having upper and lower spaced decks including a border wire and a plurality of deck wires arranged in a criss-cross fashion. The deck wires of the upper deck and lower decks are paired with one another and are connected by springs disposed between the two decks to support the decks in spaced relationship and yieldable fashion relative to one another.

Abstract: A support device having a plurality of support units, each comprising a plurality of flexible, substantially vertical support columns, with the bottoms of the support columns attached at equidistant intervals to a base member and the tops of the support columns attached at equidistant intervals to a substantially perpendicular support platform. The support columns provide directional flexibility to the columns, upon compression, to provide a substantially uniform counter-force through a range of flexion of the support columns and corresponding downward deflection of said support device. Such uniform counter-force during compression simulates a fluid-like support system. The support columns may be comprised of a solid, synthetic foam such as high density polyurethane or springs made of metal or other material. The support units preferably are arranged in a matrix to provide collective support.

Abstract: A mattress of a sofa bed contains a portion which is collapsible and portions which are conventional and non-collapsible. The collapsible and non-collapsible portions are hinged to fold within a sofa bed frame.
