Definitions

• the invention relates to a spring body of a single segment spring base of a piece of seating or reclining furniture or a mattress, each comprising a spring plate consisting of a support plate, at least one spring body and a base plate.
• a cushion element of a bed system is known, DE 297 21 656 U 1, which consists of a one-piece injection molded part and has a complicated three-dimensional design which requires complex and expensive injection molds for its production.
• the leaf springs extending outwards and upwards from a lower base plate are each provided with bearing surfaces at their ends, so that in this known one-piece embodiment of a cushion element only a compromise between the desired spring rates and the required strength of a bearing surface can be achieved.
• the object of the invention is to provide a single-segment spring base which is simple to manufacture and whose suspension properties can be optionally selected. This object is achieved according to the invention in connection with the
• the single-segment spring base consists of a separate spring body, a support plate and a base plate, the spring body consisting of spring arms arranged in a straight or curved plane around a first center and a central axis, which are to the central axis and a second spaced from the first center Center are elastically bent towards the basket and engage there with the locking means provided at their outer ends in the catches of a catch receptacle and thus form a three-dimensional spring body.
• the manufacture of the spring body can thereby be carried out considerably more cost-effectively, since the injection mold, due to the essentially two-dimensional spring body with a small thickness in the initial state, is considerably easier to manufacture and no multi-part form of the press is required.
• the spring rate can be completely independent of the strength requirements for a support plate
• Strength requirements for a support plate or a base plate for fastening a single spring element on a cross member or a flat surface of a piece of seating or reclining furniture are predetermined, since the spring body is a separate component, preferably made of an elastomer, the suspension arms of which can have different shapes that relate to the suspension - and damping properties of the spring body.
• the spring elements constructed with the spring elements can be used to create zones of different hardnesses and spring deflections, whereby the lying behavior can be progressively improved. Further advantageous embodiments of the subject matter of the invention result with and in combination from the further subclaims.
• the spring body preferably consists of three or more suspension arms, the number and geometry of which can be freely selected. It is particularly advantageous that a desired suspension hardness, spring height or also a spring rate can be predetermined via the number, length, shape, thickness and width of the suspension arms or also via the Shore hardness of the base material. This makes it easy to manufacture single spring elements of different spring rates for the different loads in a seating or reclining furniture or a mattress.
• a preferred embodiment of the object of the invention is equipped within the spring body with a second spring body with shorter suspension arms or an additional spring or damping element is used in the basket-like structure produced by the latched suspension arms, so that, for example, after a free spring travel of the outer spring body a soft spring rate a hardening spring base can be created.
• further radially extending connecting arms can extend from the first center of the spring body, the ends of which are connected to adjacent individual spring elements in the installed state of the single spring elements, so that adjacent single spring elements can be used to cushion this load when a central single spring element is loaded.
• the latches for the detents of the suspension arms are formed in one piece with a base plate for fastening the single spring element on a spring slat or a flat surface, so that the number of individual parts of the simplest single spring element to be produced is limited to three. A further minimization of the number of components can be achieved if the upper support plate is also integrally formed with the upper center of the spring body.
• a plurality of spring bodies can also be arranged one above the other in order to produce a particularly high individual spring element, in which case detent receptacles for the detents of the suspension arms of a spring body to be arranged above can then preferably be provided in the upper center of a spring body.
• Such catches can also serve as a support plate.
• suspension arms of which have lateral tabs which can be latched to tabs of adjacent suspension arms, as a result of which additional stability against lateral deflection of a single spring element under oblique loading is achieved.
• a particularly advantageous embodiment of the invention has a spring body which is designed to be divided one or more times in a vertical central plane, as a result of which the basket-like spring body can be produced by simply plugging and locking the individual spring body segments together.
• an embodiment of the invention can be emphasized in which the spring body is completely or partially or an entire single spring element is foamed with latex.
• a component can be used, for example, to equip a latex mattress, the foam-coated spring bodies or individual spring segments being inserted into a recess in the latex mattress, which is thereby considerably lighter and significantly more air permeable.
• a latex mattress with spring bodies or single spring elements made of foamed or bare plastic is much easier to handle than heavy full-latex mattresses and also has an excellent value for moisture transport, so that even highly perspiring people can use such a mattress.
