The ends of the rails are held by the support bodies in such a way that the angle between the longitudinal axes of the rail and the spar can be altered. The support bodies are ball-shaped, each having a ball cup (21) and a bearing sphere (22), where the bearing sphere is attached to the end of the rail and the ball cup is fixed to the spar.

Description

The invention relates to a spring base for mattresses from Loungers, upholstery of seating or the like according to the Preamble of claim 1.

Seating and reclining furniture generally have a spring base from a so-called slatted frame. The slatted frame of the Spring base has a plurality of spaced parallel strips, in particular female connectors. The female connectors or the like are supported by bodies connected with longitudinal spars. The longitudinal spars preferably form part of a frame, part of the slatted frame, that is, the spring base, or the seating or reclining furniture can be.

The support bodies are opposite ends of the female connectors assigned. They enable resilient storage the female connectors on the longitudinal spars. With known slats the support body are designed so that the Female connectors in a vertical direction to the seat or lying surface are easily movable and the ends of the female connectors at one Deflection their angle at a right angle to it Can change seat or lying surface level. This Known support bodies have been chosen for slat bases or slatted frames with a rectangular base, i.e. parallel longitudinal spars, proven.

For special seating and reclining furniture, suspension or Slatted frames required that have no rectangular base feature. Here the longitudinal spars run anti-parallel to each other. In this case, the support body must be anti-parallel Be adapted to the course of the longitudinal spars. However, for the longitudinal beams more or less for the respective application are at an angle to each other, are adapted support bodies in any case required.

The present invention is therefore based on the object to create a base for mattresses or the like, which are not specially adapted to the course of the longitudinal spars Support body requires.

A spring base for solving this task has the features of claim 1. In that the support body is formed in this way are that at least the angles between the longitudinal axes the strips, in particular female connectors, or the like and the longitudinal axes of the longitudinal spars are changeable the longitudinal spars have an arbitrary course to one another without the need for special support bodies. The Support body of the spring base according to the invention are the same between the longitudinal spars and the female connectors setting angle with any inclination of the longitudinal bars to each other. Leave the support body - with others Words - any misalignments of the female connectors to the Longitudinal spars in the level of the spring base or slatted frame to.

The support bodies are preferably designed as ball joints. These allow any changes in the angles of the longitudinal axes the female connectors to the longitudinal axes of the longitudinal spars, and in different - not just opposite - directions. In this way, the support body not only leave an adjustment the female connectors to different courses (parallel or antiparallel) of the longitudinal spars to each other; rather they can Female connectors like their known supports caused by a deflection of the female connectors Direction in a plane perpendicular to the level of the spring base or change the slatted frame.

According to a preferred embodiment of the invention, everyone is Support body from a ball socket and a bearing ball educated. Preferably, each female connector has on each of them opposite ends on a bearing ball during the Longitudinal pillars are assigned to ball sockets for each bearing ball, in particular in such a way that the ball sockets are immobile or are firmly attached to the longitudinal spars. By a Corresponding training of the ball cups and the bearing balls the latter are articulated on all sides in the ball sockets held, whereby the end portions of the female connectors Any direction, namely spatially on preferably one imaginary surface area of a cone.

The ball socket is designed so that it has a detachable, Allows positive reception of the bearing ball. Preferably for this purpose the ball socket is assigned a closure means. When the closure means is open, the bearing ball can be inserted into the Ball socket can be inserted. Then the closure means closed the ball socket or locked in any other way, the bearing ball is form-fitting, but on all sides pivotable, held in the ball socket.

It is also provided between the bearing ball and the Ball socket to arrange an anti-rotation device, which is formed in this way is that the bearing ball is not in the ball socket can rotate, and therefore also the respective female connector around their Longitudinal axis is not tiltable. The female connectors stop this way their relative orientation forming a flat lying surface to each other. For the rest, the bearing ball is in the ball socket can be pivoted as desired, so that the anti-rotation device the ball joint function of the support body is not impaired.

According to a preferred development of the invention Bearing ball made of an elastic material, preferably one elastic plastic, for example a polyurethane or another rubber-like elastomer. Through the the support body acts as an elastically deformable bearing ball Kind of rubber spring that deflects the female connectors as in known supports. Through the elastic bearing ball the support body receives a spring-like effect.

Further subclaims relate to advantageous refinements the spring base according to the invention, in particular the support body the same.

In the illustrated embodiment of the spring base according to the invention it is a slatted frame 10 for a piece of furniture, for example a bed. 1 shows a top view on a lying surface 11 of the partially shown Slatted frame 10.

The slatted frame 10 has a frame 12 made of two longitudinal spars 13, 14 and two connecting the ends of the longitudinal bars 13, 14 Cross bars, of which only one (shorter) in FIG. 1 Querholm 15 is shown. The longitudinal bars 13 and 14 run anti-parallel to each other by the longitudinal bar 14 under a acute angle to the opposite longitudinal spar 13 runs. The slatted frame 10 thus has a trapezoid-like base.

The slatted frame 10 also has a plurality of spring slats 16 that run parallel to each other at a distance, namely such that the longitudinal axes 17 of the female connectors (of which in 1 only one is shown) perpendicular to the longitudinal axis 18 of the (left) longitudinal spar 14. As a result of the inclination of the (right) longitudinal spar 13 to the longitudinal spar 14 the longitudinal axes 17 of the female connectors 16 at an oblique angle to the longitudinal axis 18 of the (right) longitudinal spar 13. The female connectors 16 are located in the area of the longitudinal spars 13, 14 and Cross bars 15 enclosed surface of the frame 12, wherein Top sides 19 of the spring strips 16 form the lying surface 11. On other strips or Use rods that are not necessarily bendable or have to be deflectable.

The slatted frame 10 also has support bodies 20. These are used to connect the female connectors 16 to the longitudinal spars 13 and 14 of the frame 12. The support body 20 are all equally trained. Both ends of each female connector 16 is assigned a support body 20 so that two opposite Support body 20 each have a female connector 16 with the Lägspolmen Connect 13 and 14. The support body 20 are only in FIG. 1 symbolically indicated as circles.

One of the identically designed support bodies 20 is detailed shown in Fig. 2. Accordingly, each support body sits down 20 together from a ball socket 21 and a bearing ball 22. The bearing ball 22 is on one end of the female connector shown 16 attached, preferably by friction, by the Bearing ball 22 is attached to the end of the female connector 16. Optionally, the bearing ball 22 with the end of the female connector 16 can also be glued. The ball socket 21 is fixed with a longitudinal spar, in the illustration of FIG. 2 with the left longitudinal spar 14 connected. This is preferably done by resting. The ball socket 21 has a corresponding one to the bearing ball 22 trained receptacle 23 for the most of the bearing ball 22.

By forming the support body 20 from the ball socket 21 and the bearing ball 22, the support body 20 provides a kind of ball joint This enables an inclination of the longitudinal axis 17 of the female connector 16 to the longitudinal axis 18 of the respective Longitudinal spars 13 and 14. This movement can be in any direction respectively. In particular, the angle of the longitudinal axis 17 the female connector 16 to the longitudinal axis 18 of the longitudinal spar 14 in the Level of the lying surface 11 can be changed. The different Angle between the longitudinal axes 18 of the longitudinal bars 13, 14 and the longitudinal axes 17 of the female connectors 16 are thus of the Support bodies 20 balanced use without different support bodies to have to. As a result, the frame 12 can be practically any have any footprint. The inclination of the longitudinal spars 13, 14 to each other can be of any size and it can even the longitudinal bars 13, 14 run parallel to one another, the same support body 20 always being used can. There are only correspondingly long female connectors 16 required.

The formation of the support body 20 as a ball joint enables in addition, a change in the angle of the ends of the female connector 16 if it deflects under load on the slatted frame 10. Thus, the support body 20 enables an articulated movement of the Female connector 16 in the plane of the lying surface 11 and vertically to.

3 and 4 show the ball socket 21 of the Support body 20. The ball socket 21 has an approximately hemispherical, shell-like receptacle 23 and one at the Rear of the receptacle 23 arranged holding section 24. Des the ball socket 21 also has a hinged lid 25. The Recording 23, the holding portion 24 and the hinged lid 25 of the Ball socket 21 are integrally connected. Educated is the entire ball socket 21 made of plastic, namely preferably a relatively rigid thermoplastic Plastic.

The holding section 24 of the ball socket 21 has a Vertical wall 26 forming the rear of the receptacle 23 a flat back 27. This back 27 is at Longitudinal beam 14 attached ball socket 21 on the inner, vertical Wall of the longitudinal spar 14. At the top of the Wall 26 of the holding section 24 closes a horizontal one Top wall 28. An underside 29 is also the same just trained. It lies on an upper side of the longitudinal spar 14 on. At the free end pointing away from the wall 26 Upper wall 28 is a hook projection 30 pointing downward integrally formed, which engages in a holding recess 31 on the engages upper, outer corner of the longitudinal spar 14. At the back 27 of the wall 26 is a cylindrical projection 32 with Holding ribs 33 formed on its circumference. This projection 32 engages positively in one not shown in the figures Blind hole in the inner vertical wall of the longitudinal spar 14 a. The ball socket 21 is consequently with the holding section 24 through the projection 32 and the hook projection 30 positive, in particular immovable, on the longitudinal spar 14 held. The connection of the ball socket 21 with the Longitudinal spar 14 is made latching. In the same way the ball socket 21 on the opposite, oblique longitudinal beam 13 be attached, which is of the same design, in particular has the same cross section.

On the top of the top wall 28, the hinged cover 25 is the Ball socket 21 formed with a film hinge 34. Thereby the hinged lid 25 can be folded up from the one shown in the figures Open position of the ball socket 21 to the front by 90 ° be pivoted against the receptacle 23. The ball socket 21 is thereby closed for the positive reception of the Bearing ball 22. In the closed position, the hinged cover 25 on the ball socket 21 held by two opposite Locking tongues 35, which are formed in a corresponding manner Engage openings 36 in the wall of the receptacle 23.

The underside or inside of the hinged cover 25 has one spherical cap-shaped recess 37, the corresponding to the bearing ball 22 is formed. Between this spherical cap Recess 37 of the hinged lid 25 and also part-spherical inner wall of the receptacle 23, the bearing ball 22 is form-fitting on opposite sides held in the ball socket 21, so that the Bearing ball 22 in the ball socket 21 in the manner of a ball joint in different directions on different ones Movement axes is pivotable.

Which has an essentially spherical lateral surface Bearing ball 22 has depressions 38 distributed around the circumference and two opposite longitudinal grooves 39. Furthermore has the bearing ball 22 via a central, blind hole-like franking 40. This franking 40 corresponds to the cross section the female connector 16 is formed and takes an end portion of the Female connector 16 is non-rotatable relative to the bearing ball 22. The franking 40 is arranged in the bearing ball 22 that the longitudinal axis 17 of the female connector 16 in the middle the bearing ball 22 extends and a slightly curved top the female connector 16 flat against the lying surface 11 of the Slatted frame is aligned (Fig. 2).

With the top of the female connector aligned with the lying surface 11 16, the longitudinal grooves 39 are on opposite Sides of the bearing ball 22 above and below the female connector 16. The Ball socket 21 has a projection 41 on each inner spherical surface of the receptacle 23 and under the spherical plate-shaped Recess 37 on the inside of the hinged cover 25. These correspond to the longitudinal grooves 39 of the bearing ball 22 trained and engage in this so that the bearing ball 22 with the female connector 16 not about the longitudinal axis 17 of the Female connector 16 can be rotated in the ball socket 21. This ensures that the tops of the female connectors 16 maintain their alignment with the lying surface 11, namely the top (and bottom) of all female connectors 16 run approximately in the same direction as the lying surface 11. By a selective engagement of the projections 41 of the ball socket 21, namely the receptacle 23 on the one hand and the hinged cover 25 on the other hand, is despite the anti-rotation Female connectors 16 and the bearing balls 22 in the ball socket 21 an articulated movement of the bearing ball 22 with that assigned to it End of the relevant female connector 16 in the ball socket 21 and thus a change in the angle of the longitudinal axis 17 the female connector 16 with respect to the longitudinal axis 18 of the respective Longitudinal spars 13, 14 in a horizontal and vertical plane as well as the inclined planes in between.

As can be seen in particular from FIG. 6, the Bearing ball 22 below the clearance 40 via hollow chambers 42. In the exemplary embodiment shown, three hollow chambers 42 are underneath the franking 40 is arranged. The hollow chambers 42 are preferred formed like a blind hole, namely extend over the entire length of the franking 40. If necessary, the Hollow chambers 42 but also longitudinally through the entire bearing ball 22 go through. The bearing ball 22 has through the hollow chambers 42 below the franking 40 only over relatively thin material webs, which is an elastic deformation of the below the franking 40 ensure lying section of the bearing ball 22. By forming the bearing ball 22 from one elastic material, especially an elastic thermoplastic Plastic or an elastomer, is achieved that the bearing ball 22 below the franking 40 resilient Features that when the female connectors 16 not only cause them to bend, but also a deflection of the support body 20, which to a certain extent the entire female connector 16 is opposite the longitudinal bars 13, 14 can lower.

The described support body 20 allow the formation of Slatted frames 10 with any footprint too. That's why it is Invention not on a slatted base with the in Fig. 1st shown footprint limited; it is rather suitable for Any slatted frames 10. The invention is suitable on for slat bases in which the longitudinal bars 13, 14 Are part of a piece of reclining furniture by the female slats 16 with the support bodies 20 directly on the corresponding longitudinal spars a piece of reclining furniture, for example a bed. The invention is also suitable for seating and reclining furniture preferably the spring slats 16 forming the spring base and support body 20 directly on the frame or frame of the seat or Loungers are attached. Then the slat base can be a arched seat or lying surface or separate lying surfaces in the different levels.
