Description

The The invention relates to an endpoint bearing for the lath ends a slatted base according to the preamble of the main claim.

It is known a spring device for a double slat arrangement, EP 1 472 957 B1 which also has a foot for placement on a spar of a slatted frame and two receiving caps for two bar ends, but wherein the spring element consists of three alternately arranged in opposite directions semi-cylindrical wall pieces, of which the two outer extend above the spar to the outside, so that they rest on a deflection of the slats on this and there unnecessarily limit the theoretically possible travel. The middle, inwardly extending semi-cylindrical wall piece forms in its upper region a horizontal connecting wall between the receiving caps of the bar ends, so that only a common compression of both receiving caps is possible.

From the field of mattress springs, a single spring element is known, DE 20 2006 018 923 U1 which has approximately elliptical spring elements in its cross section and the middle part spring elements have laterally two inwardly directed V-shaped notches, which have been found to be very advantageous for the spring behavior of the single spring element. Already in the well-known suspension of a bed or upholstered furniture, DE 20 2005 019 930 U1 , Such a compression element is disclosed with two opposite, arranged in the longitudinal direction of a spar V-shaped profile elements, which makes use of the advantageous profile elements.

task The invention is an endpoint bearing for the bar ends a slatted frame to provide, which the advantageous spring properties of a V-shaped profile element realized in a spring element separately for individual spring battens and realized the greatest possible travel.

The Solution to this problem arises in conjunction with the Top features according to the invention from the Technical features of the characterizing part of the main claim in particular the fact that the spring element from a from the foot part in the direction of the slats inward and upward extending lower Spring strips and one from the receiving cap towards the crossbar inwardly and downwardly extending upper spring strip and a horizontal with a point directed outward to the spar V-shaped profile element is made, these components with their inward, in the middle of a grate directed end portions connected to an outer profile element are. This profile element is preferably one-piece, could However, also be designed in several parts.

From A particular advantage here is that the individual components the profile element is not outward over the Extend the spar of a slatted frame so that the entire spring height between the underside of a straddle recording cap and the top of the spar is still available. The V-shaped profile element is inward in the direction aligned with the slats and has an approximately beak-shaped Appearance, this being at a load of the spring element easily opens, and not, as would be expected closes bellows. This allows conclusions to be drawn to draw on the force distribution in the component, that is about substantially the upper and lower spring strips the elastic deformation work take up.

The desired spring rate can in particular for adaptation at different stress zones of a bed slatted frame in dependence of Material selection and the material thickness varies widely become.

Further Substantial advantages of the inventive Endpunktlagers arise with and in combination of the following subclaims.

at a particularly preferred embodiment of the inventive Endpoint bearing extends from the outer end the lower spring strip another, inward and upward extending shorter lower support spring strip and from the outer end of the upper spring strip another, shorter and shorter inwards and downwards Upper support spring strip so in the space between the upper and lower spring strips in that the two their front ends interconnected support spring strips together form an inner support spring profile, where they preferably via a simple line connection with each other are connected or also by a V-shaped or any other shaped spring element.

This second support spring profile improves the leadership The recording caps very much, as well as the variability the entire spring element and its durability significantly increases.

In a particularly advantageous embodiment of the subject invention, the spring profile and the support spring profile is integrally formed, whereby it forms a closed spring element. It is conceivable, however, the spring profile and The support spring profile in each case build in one piece and connect to each other via mutual locking so that can be set different degrees of hardness of Endpunktlagers on the variation of the support spring profile, including the differently hard support spring profiles can be designed differently in color to their respective spring hardness in a simple manner to the outside display.

advantageously, is a separate receiving cap and each end of a spring bar also assigned a separate spring element, so that a nearly independent Reaction of an endpoint camp to a point load can.

preferably, are two or more individual receiving caps with their spring elements on arranged a common foot part, which, as it is in Bed slatted frame is common on two bearing bolts one Holmes can be placed, which in a likewise commercially available Pitch are used there.

Corresponding a further advantageous features of the subject invention the endpoint bearing can continue with a hardness adjustment device Be provided in a space between the top and lower spring strips and / or the support spring strips can be inserted or permanently in there extends and movable from a rest position to a functional position is. Such a hardness adjuster expands the possible extent in the hardness adjustability of a Endpoint camp continues very significantly, leaving a soft, very long travel to almost inelastic spring suspension a recording cap any spring situations depending can be set by the user request.

A insertable hardness adjustment can thereby from the free space between two adjacent spring elements horizontally laterally in the spaces between the spring strips and / or the support spring strips inserted or also be executed swivel. A permanent hardness adjustment device may for example consist of a flat longitudinal profile which can be polygonal or oval, being horizontal in a space between the support spring stiffeners or the spring strip extends and about its longitudinal axis so rotatably mounted, that different sized spring travel are adjustable and even the free travel of the support profile is completely lifted.

following is an embodiment of the invention with reference to drawings described in more detail. Show it:

1 a spatial view of an endpoint bearing for two slats and

2 a side view of the Endpunktlagers according to 1 ,

The endpoint camp 1 for the lath ends of a slatted frame essentially consists of a receiving cap 2 for the end of a slat of a load slat grate, a spring element arranged underneath 4 and in turn provided below footboard 3 which usually has a bolt receptacle for attachment to a bolt inserted in a longitudinal spars of a slatted base.

The illustrated endpoint camp 1 has two receiving caps 2 as well as for each recording cap 3 a separate spring element 4 on as well as a common foot part 3 with two bolt holders.

However, the scope of protection also includes endpoint storage 1 with only one pickup cap 2 over a spring element 4 on a foot part 3 as well as appropriately trained endpoint camps 1 with three or more pickup caps 2 and spring elements 4 ,

The foot parts 3 and the spring elements 4 are integrally formed here and designed as a double cap receiving cap 2 on the spring element 4 snapped.

A spring element 4 essentially consists of a foot part 3 swung toward the batten inwardly and upwardly extending lower spring strips 11 and one from the receiving cap 2 swung toward the batten inwardly and downwardly extending upper spring strips 12 and from a horizontal with its tip outward to the spar directed V-shaped profile element 7 , These components on the inside, directed towards the center of the slatted base end portions of the spring strips 11 ; 12 and the profile element 7 to a one-piece spring profile 5 connected to each other.

At a load on the endpoint bearing 1 with a vertical force deforms the beak-shaped V-shaped profile element 7 in such a way that the "beak" opens and does not fold like a baloon, as would be expected 7 a significant contribution to the lateral tilt stability of the endpoint bearing 1 ,

At the one the drawing, not shown, facing the outer rear end of the lower spring strip 11 is another shorter lower one extending inwards and upwards Support spring strips 13 and at the outer rear end of the upper spring strip 12 another inwardly and downwardly curved extending shorter upper support spring strip 14 arranged, whose inwardly directed ends are materially interconnected, so that they together form an inner support spring profile 6 form. Instead of this illustrated arcuate construction could also in the support spring profile 6 a V-shaped profile element 7 or any other conceivable profile.

The outer spring profile 5 and the inner support spring profile 6 are, as shown in the figures, together with the foot part 3 made in one piece from a plastic injection molded part. The inner support spring profile 6 However, could also, as not shown in the drawing, on locking elements optionally and interchangeably designed so that there is a use of different hard support spring profiles 6 a simple hardness adjustment of the spring element 4 and thus the endpoint camp 1 results.

Zeichnerisch also not shown are the travel 9 the spring elements 4 blocking hardening devices, which are in a gap 8th between the upper and lower spring strips 11 ; 12 and / or the support spring strips 13 ; 14 can extend, this hardness adjusting either permanently extends into it or from a gap 10 between adjacent spring elements 1 there is inserted from the side and the operation is done by an eccentric, lever, slide or a rotary knob, which is arranged on the receiving cap and actuated from above
