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.
- FIG. 1 shows an initial product of a first spring body before its elastic deformation
- FIG. 2 shows a first single spring element in the installed state in a sectional view
- FIG. 3 shows a top view of an individual segment spring base with partially spring-connected individual spring elements
- FIG. 4 shows a second individual spring element in the installed state in a sectional view 5 shows a sectional plan view of a second spring body of the second single spring element according to FIG. 4,
- Fig. 6 shows a third single spring element in the installed state in a partially sectioned
- FIG. 7 a fourth two-part spring body in a top view
- FIG. 8 the spring body of FIG. 7 in a side view
- FIG. 9 a sectional partial view of a latex mattress with individual spring elements inserted into recesses.
- a single spring element 10; 30; 50 of a single segment spring base of a piece of seating or reclining furniture or a mattress consists of a support plate 1 1; 31; 51, a base plate 1 2; 32; 52 for fastening the single spring element 10; 30; 50 on a spring slat 15 or on a flat surface 35 and at least one spring body 1; 21; 41; 61 arranged between the support plate 1 1; 31; 51 and base plate 1 2; 32; 52.
- a spring body 1 can, as shown in Fig. 1, be formed in one piece and form a single spring cage, another spring body 21, however, as shown in Figures 4 and 5, but one piece can produce two spring cages, in which
- Suspension arms 23 are bent downwards and upwards to form a second center 27 and a third center 27 '.
- An embodiment is conceivable, but not shown in the drawing, in which a one-piece spring body 1 has suspension arms 3 of different lengths, which are bent in the same direction and are each locked in two centers arranged one above the other.
- Another spring element 50 as shown in FIG. 6, can also consist of two spring bodies 1 arranged one above the other, the ends of the suspension arms 43 being mounted in a common second center 47.
- a spring body 1; 21; 41; 61 generally consists of suspension arms 3; 23; 43; 63 arranged in a straight or curved plane around a first center 6; 26; 46; 66; 66 ' and a central axis 2 Direction towards a second center 7; 27; 47; 67; 67 ' bent over on the central axis 2 and there with latching means 4; 24; 44; 64 in corresponding notches 5; 25; 45; 65 of a notch receiver 8; 28; 48; 68 intervene.
- the suspension arms 3; 23; 43; 63 can be designed to produce a desired spring base hardness or a desired spring rate in accordance with their number, shape, thickness and width, and to produce a spring body 1; 21; 41; 61 with a predetermined spring rate Starting material of appropriate Shore hardness can be used.
- tabs 16 can be formed on the side of the suspension arms, which, when assembled into a spring body 1, as shown in Figure 2, are in mutual engagement with their catches 1, 7.18 and the spring body 1 against one another Support strong lateral deformation.
- Figure 4 a variant is shown, in which a basket-shaped
- Spring body 21 a further basket-like spring body 39 or another damper body 40 of smaller diameter and lower height is used, with which the spring rate of the entire individual spring element 30 can be adjusted significantly harder from a certain spring travel.
- This version is provided with two identical base plates 32, one for fastening the individual spring element 30 on a flat surface 35 and one for fastening the support plate 31.
- further connecting arms 9 can extend radially outward, the ends of which in the installed state Individual spring elements 10; 30; 50 are connected to adjacent individual spring elements 10; 30; 50, so that all or only a few individual spring elements 10; 30; 50 can be networked with one another.
- the connecting arms 9 have latching lugs 13 at their ends, which engage in corresponding latches 14 in adjacent support plates 11, 31, 51.
- the catch receptacle 8; 28; 48; 68 of the spring body 1; 21; 41; 61 is with the
