Description

The present invention relates to an edge bearing for slats of a mattress, especially for slats for individual support elements for supporting a sitting or lying surface, with a receptacle, in particular pocket, for the end of at least one bar and a fastening part for attachment of the edge bearing to a frame, in particular one Frame longitudinal spar, according to the preamble of claim 1.

Instead of conventional slatted frames, sub-mattresses are nowadays also used in which a large number of individual support elements are distributed over the sitting or lying surface. The individual support elements are arranged on slats that span a frame of longitudinal and transverse spars. The slats can be connected via edge bearings with the longitudinal beams, which are similar to edge bearings formed by conventional slatted frames. It is advantageous here a height adjustment of the edge bearing at least in certain areas of the lower mattress in order to make an adjustment to the physique of each user.

The DE 20 2008 010 096 U1 discloses an edge bearing according to the preamble of claim 1. Further prior art is made US 4,752,981A . EP 1 820 423 A1 . EP 2 103 233 A1 and DE 100 49 944 A1 known.

The present invention has for its object to provide an improved edge bearing of the type mentioned.

The object is achieved by a peripheral bearing with the features of claim 1. Preferred developments and embodiments of the invention are specified in the dependent claims.

In the edge bearing, the receptacle is formed as a separate part, which is adjustably connected in height with the fastening part and which is displaceably guided in height via at least one guide provided on the fastening part and via latching elements in at least two superimposed positions relative to the fastening part can be latched.

Due to the two-part design of recording and mounting part, the production of the edge bearing is particularly simple and inexpensive. There is also a great deal of flexibility, since a fastening part can be combined with different receptacles.

It is particularly preferred if the guide also serves to connect the receptacle with the fastening part. Separate fasteners can be omitted.

According to a preferred embodiment of the invention, at least two guides viewed in the transverse direction of the crossbar are arranged side by side on the attachment part, with which the receptacle is selectively connectable. This creates the possibility to arrange the recording differently in the transverse direction of the bar and thus not only to adjust the height of the bar but also their position in the transverse direction of the bar, so in particular in the longitudinal direction of a bed.

Another adjustment results from the fact that the guides are designed according to a further embodiment of the invention in such a game that the receptacle is optionally latched parallel or inclined to the plane of the sitting or lying surface of the lower mattress with the fastening part. By tilting the recording and thus the lath, a lowering of a single support element can be made only on one side thereof. For an even finer height adjustment in the transverse direction of the bar, so in particular in the longitudinal direction of a bed is possible.

A stable arrangement results when the receptacle is guided according to another embodiment of the invention on two sides, in particular viewed transversely to the crossbar on its front side and on its rear side.

Likewise, an increase in the stability results if, according to one embodiment of the invention, each guide is assigned corresponding latching elements. In two-sided leadership thus also results in a two-sided latching and thus a stable connection between the receptacle and the fastening part.

The guides may preferably be formed by rails and corresponding rail receptacles, which are provided on the one hand on the receptacle and on the other part of the fastening part. Accordingly, the locking elements can be formed by in cross-section in particular elliptical locking projections and corresponding locking receptacles, which are provided on the one hand on the receptacle and on the other part of the fastening part. Both are each manufacturing technology favorable and constructively advantageous.

A simple handling of the edge bearing is obtained according to a further embodiment of the invention, according to which the locking elements provided on the receptacle are mounted between a latched and a disengaged position pivotally mounted on the receptacle. The engagement and disengagement can be done by simply pivoting the locking elements.

A structurally advantageous embodiment is given by the fact that the pivotable locking elements are arranged on a particular arranged below the receptacle, preferably connected via a film hinge with the recording bracket. The movie hinge represents one manufacturing technology favorable realization of the pivot connection, while two locking elements on both sides of the recording can be operated together by the bracket. The handling is further simplified.

According to another embodiment of the invention, the locking elements are formed by interlocking, on the one hand on the receptacle and on the other part of the fastening part provided teeth, and provided on one of the two parts teeth are provided on or on a slide plate which is displaceable between a latching position and a disengaged position , in particular by means of an eccentric device. By moving the slide plate a simple disengagement and engagement of the teeth can be effected. An eccentric means this is a particularly suitable possibility. The teeth may also be provided on a rack which is rotatable or displaceable between a latching position and a disengaged position, for example by means of a rotary handle or a slide with bevels, each with associated counter-slopes of the rack cooperate in the locking direction and in the unlocking direction, wherein connect to the acting in the locking direction bevels each locking surfaces to achieve a blocking position Also hereby results in a simple engagement and disengagement.

The teeth provided on the receptacle preferably represent a partial segment of a toothed wheel whose axis coincides with the pivot axis of the receptacle. This will change the distance between the Teeth of the receptacle and the teeth of the fastening part when tilting the recording not.

According to yet another embodiment of the invention, the locking elements are adjustable by a screw rotation between on and off position, or by a pure translational movement, in one direction, preferably against a return spring. This constructively easy to be solved adjustment options are given.

At least one pin is preferably provided on the receiving part, in which a latching element is mounted on and extendable. In particular, these pins can each be designed as sleeves, into which a corresponding pin is inserted, which forms or carries the latching element with its end pointing to the fastening part. In this way, a locking can be realized in an advantageous manner.

The other end of the bolt protrudes out of the sleeve according to a development of the invention and is provided with an actuating device, in particular a handle plate or a lever. As a result, the bolt can be actuated manually in order to engage or disengage the latching element.

According to a further embodiment of the invention, the sleeve is provided with an internal thread into which the bolt provided with a corresponding external thread can be turned on and turned off. In this way, a latching and unlatching by screw rotation can be realized.

According to yet another embodiment of the invention, the bolt is guided translationally displaceable in the sleeve, in particular by means of a pivotal lever acting on the bolt, which adjoins with one end the sleeve is supported and the other end is formed as an operating handle. Again, a simple engagement and disengagement is given, wherein the latching movement can be carried out spring assisted and wherein the disengagement can be designed self-holding. In this case, a first disengagement position may be provided, in which the bolt projects slightly beyond the sleeve, so that the latching positions of the receptacle can be sensed while the bolt is fully retracted into the sleeve in a second disengaged position. In this position, the pivot lever extends coaxially with the sleeve, so that a separately formed receptacle can be pushed onto the two pin sleeves by means of two further sleeves.

The receptacle of the receiving part can also be connected via a spring body with the fastening part or connectable. This embodiment is particularly advantageous when using the edge bearing for conventional slats of sub-mattresses. About the spring body, the spring bar is resiliently supported on the longitudinal spar.

Recording and spring body can be two separate, in particular releasably connectable parts. But they can also be integrally formed.

According to a further embodiment of the invention, the receptacle or the spring body is connected via a separate sliding part with the fastening part or connectable. As a result, the flexibility of the edge bearing can be further increased.

Particularly preferably, the sliding part has one or more, in particular two pins on which a receptacle directly or via a spring body can be placed, in particular clipped. The edge bearing can be combined with existing spring bodies for conventional slats of sub-mattresses by the spring body are placed on the pins of the sliding part. For this purpose, the pins preferably have standard dimensions.

By providing a plurality of locking elements with a small distance one above the other fine adjustment of the bar on the edge bearing is possible. Also, an inclined locking is particularly well possible. Further, an inclined locking can be facilitated by the fact that the front and rear side wall of the receptacle are formed in the center angled outward. Together with the game of the guides thereby a tendency is easily possible.

The fastening part preferably has a very small thickness, in particular a thickness of less than 4 mm, preferably about 2 mm. As a result, the edge bearing can be used with conventional strips. In addition, the strips then advantageously close flush with the longitudinal beams of a lower mattress.

That in the Fig. 1 to 5 illustrated edge bearing comprises a pocket formed as a receptacle 1 for the end of a bar and a fixing part 2 for fixing the edge bearing on a longitudinal spar of a frame, not shown here. The fastening part 2 is angled at its upper end and has in this angled region and in its lower region breakthroughs 3 for attachment to a longitudinal spar, in particular by means of fastening screws.

The receptacle 1 is formed as a separate part and adjustably connected in height with the fastening part 2. For connection, the receptacle 1 at its side facing the fastening part 2 as two Webs and cross-sectionally L-shaped rails 4 which are formed with facing in opposite directions free legs 5 on - viewed in the transverse direction of the crossbar - front end 6 and at the rear end 7 of the receptacle 1 are formed. The rails 4 engage with play in correspondingly shaped rail receivers 8, which are provided in the facing side of the fastening part 2. The rails 4, together with the receptacles 8 guides over which the receptacle 1 is guided in height displaceable on the mounting part 2. As can be seen in the figures, the fastening part 2 has a total of 6 rail receptacles 8, into which the rails 4 of the receptacle 1 can be inserted. In this way, the receptacle 1 viewed in the transverse direction of the crossbar can be connected in three different positions with the fastening part 2. Fig. 1a . c and d show a middle position of the picture 1 while Fig. 1b one on the sitting or lying surface related front position shows.

The fastening part 2 further comprises six columns of elliptical in cross-section snap-in receptacles 9, which are each arranged adjacent to a rail receptacle 8. Each column comprises seven locking receptacles 9. The locking receptacles 9 are assigned locking projections 10, which are also elliptical in cross-section and designed for latching engagement in the locking receptacles 9. Namely, two locking projections 10 are provided, which are each arranged at one end of a bracket 11 which is connected via a film hinge with the underside of the receptacle 1 and two upwardly facing arms 12 includes, on each of which a handle portion 13 is formed, which on its fastening part 2 side facing a locking projection 10 carries. The film hinge is designed so that the bracket 11 by pressing on the two handle parts 13 as in Fig. 2 to 5 shown, can be swung down. As a result, the latching projections 10 are disengaged By lifting the handle parts 13, the bracket 11 can be pivoted back, whereby the locking projections 10 engage with the locking receptacles 9, as in Fig. 1 is shown. The downwardly pivoted position is particularly in Fig. 5 clearly visible.

How to get in Fig. 1d recognizes the receptacle 1 can be locked not only parallel to the plane of the sitting or lying surface of the lower mattress with the fastening part 2 but also inclined relative to this plane. For this purpose, the two locking projections 10 are inserted at the front 6 of the receptacle 1 in a higher locking receptacle 9 than at the rear side 7. Of course, the inclination can be reversed provided by the locking projection 10 is inserted at the rear side 7 in a higher locking receptacle 9 Incidentally, the latching projections 10 can of course be inserted into any locking receptacles 9 of the same height to achieve a desired height of the latching receptacle 1 and thus the latter supported by this lath. Fig. 1a shows the highest position, the Fig. 1b and 1c the third lowest position.

That in the FIGS. 6 to 11 illustrated edge bearing according to the invention, like the edge bearing of Fig. 1 to 5 a trained as a pocket receptacle 1 for the end of a slat and a fastening part 2 for attachment of the edge bearing on a longitudinal spar of a frame, not shown here. The difference between this edge bearing and the edge bearing of Fig. 1 to 5 consists mainly in the type of locking between the receptacle 1 and the attachment part 2. These differences will be discussed below.

Also in this edge bearing, the receptacle 1 has webs 4, which engage in rail receivers 8 of the fastening part 2. The webs 4 are also formed substantially in cross-section also L-shaped, wherein the outwardly facing legs 5 each have a provided with teeth 14 edge, wherein the teeth represent a partial segment of a gear whose axis coincides with the pivot axis of the receptacle 1. The teeth 14 are opposed to corresponding teeth 15, which are each provided on a slide plate 16. The two slide plates 16 are integrated into the fastening part 2 and therefore in Fig. 6 covered by the facing for receiving 1 wall of the fastening part 2. The slide plates 16 are in the transverse direction of the male lath between the in Fig. 7 shown engaged position and in Fig. 8 shown disengaged engagement position. As can be seen, the receptacle 1 can be moved in the disengaged position in height and tilted relative to the plane of a sitting or lying surface. In this tilted position, the receptacle 1 via the teeth 14, 15 are also locked. Of course, the recording 1 can be locked in an inclined position in any altitude. The lowest position is exemplary in Fig. 7 shown.

The displacement of the slide plates 16 between the two positions via an eccentric, which in detail in the 10 and 11 is shown. The eccentric device 17 comprises an outer ring 18, on which an upwardly facing actuating lever 19 is arranged. On the inside of the ring 18 is provided with two opposing eccentric surfaces 20. Connected to the outer ring 18 is further an inner eccentric disc 21, which forms two eccentric guide slots 22 with the eccentric surfaces 20. In these guide slots 22, two half-moon-like blocks 23 are received, which are each connected to a slide plate 16. So while the inner eccentric disc 21 with the outer ring 18 is rotated about an axis perpendicular to the front side of the attachment part 2 upon actuation of the lever 19, the two crescent-shaped blocks 23 move together with the slide plates sixteenth

How to compare by Fig. 10 With Fig. 11 detects, leads a rotation of the eccentric 17 via the lever 19 of the in Fig. 10 shown release position in the in Fig. 11 illustrated locking position by the two crescent-shaped blocks 23 are moved toward each other by the two eccentric surfaces 20. Since the inner eccentric disc 21 rotates with it, the corresponding space between the two blocks 23 is sufficiently released. By pivoting the lever 19 in the reverse direction, ie from the in Fig. 11 position shown in the in Fig. 10 shown position, the inner eccentric disc 21 rotates in the opposite direction and thereby pushes apart the two crescent-shaped blocks 23 apart. Since the outer ring 18 rotates back with, here the corresponding space outside the two blocks 23 is released. In this way, by simply reciprocating the lever 19 between the release and locking position of the teeth 14, 15 are selected to achieve a height adjustment and optionally tilting of the receptacle 1 and their locking in the desired position.

In the in the Fig. 12 to 15 Edge bearing shown in each case a plate 24 is integrally formed on the front 6 and on the back 7 of the receptacle 1, which terminates flush with the mounting part 2 facing side of the receptacle 1. The two plates 24 each carry a pin-like sleeve 25 which is provided with an internal thread. The screw axis of the internal thread extends perpendicular to the flat side of the fastening part 2. In the internal thread of the two sleeves 25 is one in each case Threaded bolt 26 is screwed in, which protrudes with its one end over the fastening part facing away from the end of the sleeve 25. At this protruding end, the threaded bolts 26 are each provided with a handle plate 27, via which the threaded bolts 26 in the internal threads of the sleeves 25 are rotatable.

The other end of the threaded bolt 26 terminates in a first rotational position flush with the mounting part 2 facing side of the receptacle 1, while in a second rotational position on this side and protrudes into one of the locking receptacles 9 engages. Details on this correspond to those of the further exemplary embodiments of the invention described below.

In the in the Fig. 16 to 24 illustrated embodiment of the invention, a separate sliding plate 28 is provided, with which a receptacle, not shown here for a slat is connectable. The recording may be a recording according to the Fig. 1 to 15 act, which serves to receive a support bar for individual support elements. But it may also be a receptacle for a conventional spring strip of a mattress. Such a receptacle is then connected in particular via a spring body with the separate sliding plate 28. Recording and optionally spring body then form together with the sliding plate 28 and the fastening part 2, the edge bearing for the spring bar.

The separate sliding plate 28 is like the recording of the Fig. 12 to 15 provided with two peg-like sleeves 25. As there, the sleeves 25 have internal threads, in which threaded bolts 26 are screwed with handle plates 27. By twisting between a first position and a second position, the threaded bolts 26 can with their from the handle plates 27 remote ends are inserted into the locking receptacles 9 of the fastening part 2. By reversing the rotation of the threaded bolt 26, these can be rotated out of the locking receptacles 9, so that the sliding plate 28 can be moved in height.

The FIGS. 20 to 22 show the sliding plate 28 with two different rotational positions of the threaded bolt 26. So is located in Fig. 21 the right threaded bolt 26 in the screwed-in position, in which it projects beyond the fastening part 2 facing side of the sliding plate 28 and engages in a latching receptacle 9, while the left threaded bolt 26 is in an unscrewed position in which he does not have the said side the sliding plate 28 protrudes, in particular flush with this side. This is especially in Fig. 20 good to see. In the Fig. 18 . 20 and 21 is also good to see that the sliding plate 28 according to the in the Fig. 1 to 11 described embodiments with rails 4 is provided, which are guided in rail receivers 8 of the fastening part 2 in height displaceable. The same applies to the embodiment of Fig. 12 to 15 , in particular, in Fig. 14 recognizes. The height adjustment is thus essentially the same in all embodiments, only the locking is different. In all embodiments, therefore, as in the FIGS. 23 and 24 illustrated for the fourth embodiment, an inclined adjustment of the receptacle 1 and the sliding plate 28 are made.

At the in Fig. 25 shown fifth edge bearing according to the invention are to fix the receptacle 1 relative to the fastening part 2, two racks 29 are provided, which between a in Fig. 5 Latch shown on the left, in which the teeth 30 of the rack 29 with the teeth 14 of the receptacle 1 are engaged, and a right in FIG. 25 shown Ausraststellung in which the teeth 30 of the rack 29 are rotated out of the plane of the teeth 14 of the receptacle 1 about an axis I, are rotatable. The twisting of the racks 29 via one attached to these rotary handle 31. With teeth twisted 30, the receptacle 1 can be adjusted in height and, if desired, tilted and then locked by turning back the racks 29 in the desired position.

At the in Fig. 26 shown sixth edge bearing according to the invention, the fastening part 2 has two racks 32 which are in the plane of the fastening part 2 between a first position in which the teeth 33 of the racks 32 with the teeth 14 of the receptacle 1 in engagement and a second position, in which the teeth 14, 33 are disengaged, are displaceable. The displacement of the racks 32 via a respective slider 34 which is displaceable perpendicular to the direction of movement of the racks 32 in the plane of the fastening part. The slides 34 have two types of ramps 36 and 37, which cooperate with corresponding counter-slopes 38, 39 on the racks 32, as shown in the FIGS. 27 and 28 is shown in detail. Fig. 27 shows the latched position in which the slider 34 is pressed down. In this position, locking surfaces 40 and 41 are opposite, which are provided on the one hand to the racks 32 and on the other hand on the slider 34. As a result, the engagement position of the teeth 33 of the racks 32 with the teeth 14 of the receptacle 1 is blocked.

When pulling out the slider 34 upwards the ramps 37 of the respective slider 34 run on the counter-ramps 39 of the associated rack 32. As a result, the respective rack 32 is moved laterally outward in the unlocked position. Now the recording 1 adjusted in height and tilted if desired. By subsequently pushing down the slider 34, the racks 32 are moved back into the engaged position of their teeth 33 with the teeth 14 of the receptacle 1 by the run-on slopes 36 of the slider 34 run onto the counter-ramps 38 of the associated rack 32 until finally the locking surfaces 40, 41 of the slider 34 and the rack 32 are again opposite to each other.

In the in the Fig. 29 to 31 shown seventh embodiment of the edge bearing according to the invention, as in the fourth embodiment, a sliding plate 28 is provided, to which the receptacle 1 can be applied as a separate component. The sliding plate 28 is, as in the fourth embodiment, provided with two sleeves 25, which, however, have no internal thread. Instead, the sleeves 25 form an axial guide for each bolt 42, which by means of a rotatably hinged thereto, supported on the sleeve 25 pivot lever 43 between a in the FIGS. 30 and 31 shown on the right extended position and one in Fig. 30 shown first or one in Fig. 31 shown second retracted position is axially displaceable. In the in Fig. 30 illustrated first retracted position of the bolt 42 projects a small distance over the sleeve 25, so that the locking receptacles 9 in the fastening part 2 can be felt. In the second retracted position of Fig. 31 are the pivot lever 43 in a completely coaxial with the sleeve 25 position in which a recording with corresponding further sleeves on the sleeves 25 of the slide plate 28 can be pushed. Alternatively, a receptacle, as stated in the fourth embodiment, could also be clipped from above onto the sleeves 25 or connected in any other way to them. The adjustment of the bolt 42 in the retracted position takes place otherwise against a return spring 44. The first and the second retracting position of the bolt 42 are as self-retaining Performed positions, so that the pivot lever 43 during adjustment of the sliding plate 28 and when applying the receptacle 1 need not be held.

As can be seen from the above statements, the edge bearing according to the invention is particularly flexible and allows a high adjustability of a slat, in particular serving as a support of individual support elements of a mattress lath. The edge bearing can also be used for conventional slatted frames. Particularly favorable is the production of the edge bearing made of plastic. The receptacle 1 and the fastening part 2 can each be integrally formed.
