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). The invention also seeks to provide a bed system that is fitted with the inventive bearing elements, and which is characterized by its versatility. To this effect, fixing means for bearing elements are fitted on the plate or laths, preferably as undercrosses (30) that can be connected by socket connectors, with fixing means for the bearing element (10, 20) in the crossing area. A second version of the invention is intended in particular for lath frames (2) with mountable frame part(s) (3, 5, 7). In this version, at least one row of bearing elements (30') belonging to the outer mountable frame part is fitted with bearing elements (35') having a foot support (31) and a bearing plate (20, 40, 50). The other rows have bearing elements (30), which comprise a foot support (31), spring body (35, 35') and bearing plate (20, 40, 50).

Description

The invention relates to an injection molded part made of an elastomer Support element for upholstery, especially for ventilated ones Upholstery pad like upholstery. Mattress or the like of seating or lying areas, that can be attached to a base with a base is, has a cushion-receiving platen, in which between Base and platter at least two starting from the base Spring elements with leaf spring-like support arms (12; 22) in the direction the effective bearing force directional travel, their respective outer ends open into the support plate, are provided; it concerns also a bed system built on such support elements.

Upholstery pads serve to support a cushion on which the body is placed is physically fit. Such is according to EP 0 401 712 Upholstery pad known, covering the entire surface of the pad is covered with elastic elements to avoid overloading and to limit the available spring travel in U-profiles are stored so that for surface storage for lying or seating furniture, for beds or the like, the support surface for a cushion cover like a mattress - as already known from DE 36 12 603 A1 - is broken down into partial areas arranged in a regular pattern and each of these spring elements is resilient is trained. Upholstered pads absorb body moisture on and soak in the course of a sitting or lying time in particular where people are in a damp atmosphere for long periods of time lie and a moisture-impermeable underlay is provided - for example in caravans or in boats. EP 0 653 proposes ventilation 174 proposes to provide the support plate with openings. Unsatisfactory remains with these proposals that the height of the individual support elements must be (relatively) large, since the available travel represents a fraction of the height of the unloaded support element.

A frame for reclining or seating furniture, its longitudinal and cross bars are provided with easily mountable spring elements, describes the DE 196 37 933 C; these spring elements support support plates to which the mattress or a cushion rests. The spring elements are formed by lying leaf spring elements, which are approximately C-shaped mirror-symmetrical to each other so arranged are that the lower leaf spring is supported in the center of the spar and the upper leaf spring supports the support plate in the middle.

GB 2 143123 describes a movable pad for upholstery or the like, in which a number of annular connecting members by means of Clamping bodies are interconnected. Such a document is stable in itself through the connection and does not require any additional pad, the mobility of the pad in however, no force-coordinated support is allowed. A other mattress pad with elastic surface, put together from a variety of foam blocks, describes DE 196 00 434; it is suggested that to reach one of the supported Body region adapted hardness foam blocks different Hardness should be used. One of individual support elements with at least the base and platter do not describe either.

Finally, DE 295 05 052 U describes a support element, at which is a cross lattice of intersection pieces and arms is formed, wherein on the crossing pieces and / or the arms spring body with the head side attached support plates are clipped on. Here are the Lock parts designed differently, a mere putting on the Plates on the base are not possible.

From this follows the task on which the invention is based further develop known support elements so that the travel is a accounts for a significant share of the total amount, whereby with received Ventilation of the support element is easy and economical to manufacture and should be widely used: a bed system should also be used be proposed with such support elements that for versatile Use should be simple and economical to manufacture.

This object is achieved according to the invention by the in the independent Features reproduced: advantageous further developments and preferred embodiments each describe thereon back-related subclaims.

To achieve the suspension in a first embodiment, are at least three or four support arms directed outward from a base provided that act as leaf springs in the direction of the Contact force directed spring travel are formed. On each of these Support arms are provided with a support surface at the end; this Support surfaces of a support element together form the cushion receiving support plate to which they are between the support surfaces in the Area of bridge connectors are attached. These contact surfaces are pushed outwards when the springs are pressed through. With others Spring elements are now coupled to these contact surfaces so that the Outward movement spans these additional spring elements. Do it both springs in the same direction: Will the springs of the support arms through Depressed, cause those moving outward Support plate tensioning the other spring elements, so that ultimately the spring characteristic of the support element through the combination both characteristics as required or set as desired can be. By the possible lowering of the contact surfaces down to the basis can be reached spring travel that - except for material thickness - correspond to the height of the support element itself.

These support arms are arranged rotationally symmetrically; so the Angular distance from three support arms 120 ° and from four support arms Is 90 °. Become the leaf springs forming the support arms designed in such a way that their spring constants are the same even with lateral power components, a lowering without (that of other upholstery elements known) "tilting", so that a proper Upholstery is achieved. Are those that form the support arms Leaf springs are designed so that their spring constants are the same, there is also a lowering without lateral force components (that known from other upholstery elements) "tilting" so that a proper Padding is achieved; it goes without saying even that the spring constant is selected independently. Contains the platter by appropriate training of the Contact surfaces an inner free space, at least the size of the base, spring travel can be achieved, which - apart from the material thickness - The height of the support element itself correspond, so that this lowering can even take place to the level of the base. there it is advantageous if the support arms delivering the spring force from a corresponding high-quality elastomer, the contact surfaces are made from economical plastics: such double plastic articles can be sprayed using the two-component process or manufacture in change machines.

An advantageous training sees wave springs in the course of the support arms as spring elements. The extension of the support arms leads to one Compression of the corrugated spring due to the change in position of the contact surface is counteracted. The coupling spring elements are called between the bearing surfaces divided here, connecting these OMEGA-like springs provided. Especially the last allowed a travel that is not reduced by undulations. Means of these further spring elements, these contact surfaces are now such coupled that the outward movement a tensioning of these further spring elements has the consequence. Both springs work in the same direction: If the springs of the support arms are tensioned by pressing them down, cause the outward-moving platen tension of the other spring elements, so that ultimately the spring characteristic of the Support element set by the combination of both characteristics can be as required or desired.

To attach these support elements to a base, the Base designed accordingly: Should height differences in the attachments be balanced so that all support plates in one Level, the base is advantageous as a base plate or as a base body appropriate height trained. With an apprenticeship provide the base plate / base body with a central hole. Here is attached with a screw or with a dowel, whereby Penetrate screw or dowel into the base. In an analogous way the base plate is provided with two holes or dowels that are covered diametrically opposite each other on the center of the base plate. It is also fixed here using screws or dowels; this is because of the screwed or dowelled connection the hole arrangement secured against rotation. Is on the pad T-shaped bracket attached, has the central hole for secure attachment with overlap of this holder at least one, preferably however two flattened sides arranged opposite each other on. The flattening can be used to attach the T-shaped holder be applied to the pad; The support element is then put on and fixed by turning about 90 °.

In another embodiment, the base plate has hook-shaped strips on; these strips are included on the base Holding elements together so that the hook-shaped strips with corresponding Interlocking projections on these holding elements form a positive connection. Are these hook-shaped Moldings are elongated and on both sides of the center of the base plate arranged, they form part of a sliding connection, whose other. Part of the holding elements provided on the base form so that the support elements on such holding elements can be postponed; at curved and diametrically opposite each other strips arranged with respect to the center of the base plate they form one part of a screw cap, the other part formed by correspondingly provided on the support elements become. The support elements are here in the manner of a bayonet Twist lock can be screwed onto the holding elements. Advantageous are the strips for limiting the sliding or turning path with locking devices Mistake. With both arrangements, the support elements simply and securely set on the base, the locking means allow the desired positioning to be fixed.

In a second embodiment, the suspension is achieved. that the support element one between a foot and a Has support plate arranged spring body, the foot receptacle with one closure part and the support plate with the other Closure part as a means for fixing and releasable intermediate joining of the spring body as well as for the detachable mounting of the support plate the footplate is provided. This spring body in turn instructs the upper part of the closure at one end and the lower part at the other end of the closure and so can with its spring body end on the base plate and with its other spring body end the support plate are attached; Foot support and support plate get a larger distance through the inserted spring body from each other. A resilient support element is thus obtained. that with different high spring bodies, in different Heights can be used, thus allowing a height compensation, where the height of the spring body is the height of the bearing surface certainly.

A flat support element is made up of the combination of one a footprint with a support plate alone formed with a closure, advantageously as a bayonet-type Twist lock, are joined together at the projections in recesses shaped like a segment of a circle, which are in the central part of the Support plates are provided, interlocking allow rotation. The projections are advantageous as mushroom-shaped, through recesses in the central part engaging and engaging knobs. Means are provided for locking that interact in a latching manner, and generally from noses. Pimples or the like as well as from corresponding recesses or depressions are formed.

As a spring body between the spring body foot and spring body head are at an embodiment two with their tips directed towards each other Double polygons are provided, the outward facing surfaces of which Spring body, and form the spring body head. The directed against each other Polygon peaks are merged so that between a pipe section with a substantially rectangular cross section is formed, which acts as a tubular spring and stabilizes the polygon spring and when pushing through a support with its own spring characteristic forms. In another embodiment, the spring body is from a single polygon. Here form the outside of the Polygons the flow plate or the spring head, while the side form outward-facing tips. There is a piece of pipe on the inside of the spring body head molded, which - similar to the Bourdon tube with the double polygon - one Half-tube spring that forms when pressed against the inside of the spring body foot and so a support with its own Spring characteristic forms.

The support plate detects three or four in one embodiment external support arms, each opens into an external support surface, which are arranged opposite each other. Further the support plate has an inner support surface, supported the central plate. Radial connectors connect the central plate with the outer support surfaces, the outer support surfaces in height arranged higher than the inner contact surface is. In a further development, the support arms are between middle outer surfaces of the outer and inner contact surfaces provided the heights above the inner but below molded onto the radial connector of the outer contact surface are inclined to this. This height Grading results in a significant reduction in back cover the mattress or the like. The contact surface becomes advantageous with bent edge areas with a C or U-shaped cross section at least stiffened the outer contact surfaces.

To lower the stepped contact surfaces, adapt to the requirements to be able to, are the radial connectors as the individual contact surfaces connecting webs formed, the rigidity of the for determine the lowering necessary force. To adjust these powers these webs meet the requirements in terms of width and thickness customized. In a preferred embodiment, these webs are as Spring bars formed, the spring bars preferably with corrugated springs are provided as spring elements. The spring elements are through the appropriate shape to the desired or required force ratios customizable. Through this training, the rear ventilation sustainably improved, although it is advantageous if independent of which the Radal connectors and / or contact surfaces with ventilation openings are provided; besides, there will also be an improved adjustment to reaches physiological sleeping posture.

One embodiment has three, the other four support arms in Angular distance of 120 ° or 90 °; when putting together several Can support elements with support plates to a cushion pad these support arms of adjacent support plates are placed in such a way that there is an (almost) continuous contact surface, especially if the support arms are shaped accordingly. With three-armed support plates the support plates are arranged "turned", so that two support arms each of the one support plate with one support arm of the adjacent support plate. At four Support arms these are advantageous with a slatted frame as a substructure posed that the crossbar lies "at an angle" to the crossed support arms.

In an advantageous development, there are between the bearing surfaces adjacent support arms connecting bows provided as coupling webs; all contact surfaces together with the coupling webs form one closed structure. These coupling webs cause the individual Cannot move support surfaces independently of each other, but that the movement of one contact surface affects neighboring ones Transfers contact surfaces. The coupling webs advantageously form springs, for example as OMEGA-shaped flat springs or as wave springs are trained. With the OMEGA-shaped design, the opening is the OMEGA facing outwards and its two feet with the two Support surfaces of adjacent support plates connected. To repeal the stiffening are the bent edge areas of the outer contact surfaces exposed in the area of the coupling webs. With training The degree of coupling of these springs can be set so that the desired spring properties can be obtained.

In another, also advantageous embodiment, the Plates closed in a ring. The contact surfaces are here also stepped, with each outer contact surface opposite of the inner contact surface / -chen has a height that related is higher on the top of the headboard from the footboard. The ring-shaped Contact surfaces are connected to each other via radial connectors, whereby these are formed obliquely. Radial connector and / or contact surfaces can be provided with recesses in order to Further improve rear ventilation. Two rings are advantageous here closed, interconnected via radial connectors, stepped contact surfaces provided; in the case of further training there are three closed in a ring, connected to one another via radial connectors Contact surfaces provided. The shape of the ring-shaped contact surfaces a circular shape or - alternatively - a square shape.

In a preferred embodiment, the support element is a plastic injection molded part. This design allows the support element produce in a simple manner; the cost of the injection mold lead to because of the large number of support elements no noticeable increase in the price of the individual item. Here it goes without saying of course that for the production of such support elements with regard their resistance to mechanical loads or chemical Selected plastics are used which influence the have sufficient durability. As such plastics are preferably thermoplastic elastomers used.

In order to manufacture a bed system with these support elements these support elements placed on a plate or on a slat determined what appropriate fasteners for attaching the Support elements are provided. When training is on the Plate a grid undercarriage elements with fasteners for the support elements in the crossings. The single ones Lower crosses, the number of which corresponds to the number of support elements, can be joined together using a connector.

In one embodiment, the support element is on a plate a grid pad placed on the plate or on a slat fixed by gluing or welding, by another Screws (alternatively nailing or stapling) or through dowels. At a another embodiment is the support element on the plate the lattice base placed on the plate or on the crossbar by pushing it into a slide-in connector or by screwing it in in a twist lock, the latter on the plate on which placed on the plate or on the slat in the Number are provided, the number of those provided in the lying area Number of support elements corresponds.

The second embodiment of a bed system equipped with such Support elements, in addition to the resolution of the seating / lying area also gradations in the lowering, so that greater upholstery comfort It is to be expected that the support elements according to the invention differ Have heights. So zones can be different Lowering in a surprising way just form that in the zone low stress - for example head area, lower leg / foot area - Support elements without spring body between the foot support and Support plates are provided, the slats here with the known Step dowels are set "high". In the zone with increased stress - around the thigh, pelvis. Fuselage - become on the other hand, support elements with between the foot support and the support plate arranged spring bodies provided, the slats here by means of the step dowels are set "low".

This results in different depths sinking in transversely to the slat extension Zones. which compensates for the different in these zones Form loads. But also within the zone area of one There is no skewing of the slat, the slat ends lie in one Height, the lowering result selectively by the individual Support elements. At least two zones are advantageously provided, a zone with support elements, formed from a base plate and support plate and a zone with support elements, formed from a foot support, Spring body and support plate, with step dowels that have a high and a low position allow the first zone to be higher and the second Zone are arranged in a lower position on the frame. Here is the second zone with support elements with spring body essentially in provided in the middle of a slatted frame, corresponding to the location the buttocks of a person lying down. On both sides of this second zone is ever a first zone with support elements without spring body is provided.

The frame is advantageously provided with a hinged frame part, what the frame has opposite joints. In order to at least one frame part can be set up; in training too the second frame part designed to be erectable. It is also advantageous to link another frame part to the erectable frame part, this in turn with at least two slats with support elements is provided. This frame part forms for a slatted frame a bed a headrest, for example for reading. Each of the opposite the base frame that can be set up has at least two Rows of support elements on. At least one row points the support elements of the exterior of the erectable frame parts support elements on, formed from the foot support and the platter, while the other rows with support elements, made up of foot supports. Spring body and support plate are provided. The bottoms and / or the support plates and / or the spring body of the two embodiments are advantageously designed as plastic injection molded parts, and can be produced economically in large quantities.

The support plate 40 has a lower plate 42; in the two that corresponding other part of the rotating bayonet lock, Circular segment-shaped recesses 43 are provided. In these recesses 43 the circle segments 32 are inserted when foot pickup 31 and support plate 40 are to be connected. By twisting of the support plate 40, the projections 33 engage behind the edges of the Recesses 43 so that there is a fixed connection. Further recesses 44 are provided in the lower plate 42; in these recesses 44 engage the knobs 34 of the foot receptacle 31, so that a turning back only by overcoming the locking force of the thus formed Snap connection can take place. The spring body 3 is designed that it is inserted between foot holder 31 and support plate 40 can be. The spring body head 35.2 is correspondingly with circular segments 32 (see FIG. 9), which cooperate with the recesses 43 can, so that the support plate 40 also on a high spring body 35 or low spring body 35 'can be placed.

Figures 9 and 10 show spring bodies 35 and 35 'in perspective Scheme or in side view. A high spring body 35 - as in 10a shown - is formed by a double polygon 38, the sides facing away from the spring body foot 35.1 or the Spring body head 35.2 are formed; those facing each other Tips 38.1 of the polygons 38 are formed into a tubular spring 39.

For a support element of medium height - Fig. 10b - is a spring body 35 'provided, the resilient element as a single polygon 35' is trained. Here, the tube spring 39 is on the inside the half-tube spring 39 'formed on the head plate. Both spring elements 35 and 35 'have the same spring body 35.1 and the same Spring body head 35.2, so that this spring body 35 '- like described above - between foot mount 31 and support plate 40. 50 or 60 can be inserted. The same spring body feet 35.1 of both spring bodies 35 and 35 '(Fig. 10c) point - analogously to the lower plate 42 of the support plate 40 - circular segment-shaped recesses 36 and knobs 37 on the one part of a twist lock - Form according to the above - so that both the spring body 35 and the spring body 35 'analogous to the support plate 40 can be set on the foot receiver 31. The pimples 37 engage in recesses 34 after rotation, and thus secure the Spring body 35 against turning back and thus against loosening. The spring body head 35.2 (Fig. 10d) is - analogous to foot mount 31 - with two circle segments forming part of a twist lock 32 provided with projections 33 with the recesses 43 of the lower plate 42 cooperate in the sense of a twist lock, whereby the spring body head 35.2 has knobs 37, which in the recesses 44 snap in and so - in the manner described - an unwanted Prevent loosening of the support plate 40 from the spring body 35; the wedge-shaped Knobs 37 (see partial section next to Fig. 10c) facilitate this Lock the lock and make it difficult to release it.

These spring bodies 35 and 35 'obtain the spring properties from the elastic walls of the polygons 38 and 38 'with the outside directed tips 38.2 or 38.2 ', they are here from the material constants as well as determined by the geometry. To bounce by far of the spring body 35 or 35 '"stiffening" of the spring action reach is a Bourdon tube 39 (Fig. 10a) in the area of each other directed tips or one of these corresponding to the inside of the spring body head 35.2 molded half-tube spring 39 ' (Fig. 10b) provided. This Bourdon tube 39 or 39 'causes the spring body head 35.2 with heavy load against the Bourdon tube puts and presses it on the spring body foot 35.1. This makes the Bourdon tube 39 as an independent spring with a different spring characteristic, which now regulates further compression, the spring constant increases accordingly, so for a further impression a disproportionately greater force than previously required.

The outward tips 38.2 can be used to adjust the spring constant to the desired values and to absorb lateral thrust connected by the feed bridging, arch-shaped support tabs 35.3 be (Fig. 9a); another possibility is approximately circular section Recesses 35.4 of these outward tips 38.2. Become recesses 35.4 at the outwardly directed tips 38.2 or 39.2 'of the polygons 38 or 38' provided behaves the spring body also moved together like a ball bearing: the patch The platen is yielding in every direction.
