Abstract

The frame has several interconnected elements (22, 23, 24, 25) of which at least one can swivel relative to the or each other elements. The elements are horizontally slidable relative to the frame (21). One element which is to be swivelled is connected to the frame by at least one coupling member (31) so that when the element swivels a free end of same is moved up and down vertically but is immovable horizontally. The or each element is mounted horizontally displaceable in guide rails provided on the longitudinal beams (29) of the frame. The guide rails can be fixed immovable and can be inclined relative to the long beams.

Description

The invention relates to a slatted frame, in particular for a Lounger, with a frame and with several articulated with each other connected elements, with at least one element facing the or any other element is pivotable.

Slatted frames of the type mentioned are adequate known. The articulated elements of the Slatted frames serve to support various parts of the body a person lying on the slatted frame. A head and Upper body support element is usually called Called head element. It supports the feet and legs Element is called foot element. Between Head element and foot element is in known slatted frames arranged at least one further element that the support serves the buttocks part and is referred to as the buttocks element.

In known slatted frames, when pivoting an element, especially the head element, a free end of the Head element moves on an arc-shaped path. hereby the distance between the torso changes person lying on the slatted frame and, for example, one next to him the bedside table. After swiveling the slatted frame is therefore due to the change in distance the bedside table for the person lying on the slatted frame hard to access. This is a disadvantage.

Proceeding from this, the present invention has the problem based on providing a slatted frame that on the one hand Avoids the disadvantage described above and on the other hand with little constructive effort can be produced.

To solve this problem is the slatted frame mentioned at the beginning characterized in that an element to be pivoted about at least one coupling element, in particular with a frame is connected such that when pivoting the element free end of the same in the vertical direction is movable and immovable in the horizontal direction, and at least part of the remaining elements compared to the Frame is essentially horizontally displaceable.

The invention is therefore based on the idea of the free end of the element to be pivoted not on an arc Web, but to move on a vertical web. The horizontal elements that usually arise when the element is pivoted Movement component of the free end is the horizontal Movability of the elements in relation to the frame compensated. The coupling element is important in this context, the horizontal when swiveling the element Displacement of the elements relative to the frame. This The solution is of particularly simple design effort.

The slatted frames shown in the drawing above all find Use with couches, hospital beds or the like. she serve to support one on the couch or one in the Person lying in hospital bed.

1 to 8 show a slatted frame 20 according to a first embodiment the invention in various representations.

The slatted frame 20 shown there has a frame 21 as well as via four articulated elements 22, 23, 24, 25. The frame 21 does not have to be part of the slatted frame Be 20. It can also be the body of the bed or the like form on or on which the elements 22, 23, 24, 25 support. The slatted frame 20 is then essentially only the elements 22, 23, 24, 25 are formed. Two adjacent ones Elements 22, 23 and 23, 24 and 24, 25 are each over a Joint 26 or 27 or 28 connected to each other. The frame 21 is by two parallel longitudinal spars 29th and transverse bars 30 running perpendicular to the longitudinal bars 29 educated.

The elements 22, 23, 24, 25 of the slatted frame 20 are used for support different body parts one on the slatted frame resting, not shown person. The side or outer element 22 is used to support an upper body and head of the person lying on the slatted frame 20 and is therefore also referred to as the head element. That too outer or lateral element 25, on the other hand, is used for support the feet and legs of the person resting on the slatted frame 20 and is therefore also called a foot element. Between outer or lateral elements 22, 25 - that is, between the head element and foot element - the elements 23, 24 are arranged. The elements 23, 24 of the slatted frame 20 are used for support a buttocks and the thighs on the slatted base 20 resting person. The element 23 is therefore usually also as the buttocks element, the element 24 referred to as the leg element.

The peculiarity of the slatted frame 20 can be seen in that on the one hand, the elements 23, 24, 25 relative to the frame 21 in are horizontally displaceable and on the other hand, the element 22 to be pivoted - that is, the head element - On both sides of the same one Coupling member 31 is connected to the frame 21. This is ensures that when pivoting the element 22 a free End 32 of the element 22 only in the vertical direction is moved up and down. The when pivoting the element 22nd Movement components usually arising in a horizontal Direction is compensated so that the free end 32 of the Elements 22 is immovable in the horizontal direction.

To ensure that the elements can be moved horizontally 22, 23, 24, 25 opposite the frame 21 is the element 23 - So the seat element - horizontally displaceable on the frame 21 stored. For this purpose, the longitudinal spars 29 of the frame 21 Guide rails 33 arranged which are immovable to the Longitudinal bars 29 of the frame 21 are fixed. In these guide rails 33, the element 23 is mounted horizontally displaceable. To this end, the elements 23 that laterally delimit Joints 26, 27 with means not shown in detail in the Guide rails 33 a. It is also possible that the joints 26, 27 on right-angled guide rails glide along.

Characterized in that the element 23 in the guide rails 33 horizontally is slidably mounted, all elements 22, 23, 24, 25 relative to the frame 21 in the horizontal direction. This results from the fact that the elements 22, 23, 24, 25, So all the elements, about the joints 26, 27, 28 with each other are connected. Due to the horizontal movement of the Elements 23 and the connection of elements 22 and 23 through the Hinge 26 is part of the element 22 when pivoting can also be moved horizontally, despite the horizontal Direction of immovable free end 32 of the pivotable Elements 22. Provided of horizontal displaceability element 22 is also mentioned, this is the free end 32 of the element 22 except what, according to the invention, only in is essentially vertically up and down when the element 22 is pivoted.

The coupling member 31 is on the one hand with the element 22 - ie with the head element - and on the other hand connected to the frame 21. With a first end section 34, the coupling member 31 is over a first joint 35 with the frame 21, namely with the Cross bar 30 of the frame 21 connected. With one of the first End portion 34 is opposite second end portion 36 the coupling member 31 via a second joint 37 with the one to be pivoted Element 22 - connected to the head element. The first joint 35 is fixed on the frame 21, namely arranged on the cross member 30. The second joint 37 is together with the element 22 relative to the frame 21.

When pivoting the element 22 from the horizontal position 2 in the inclined position shown in FIG. 1 Element 22, which at its free end 32 opposite End in the joint 26 is connected to the element 23 to the Joint 26 pivoted upwards. In that the element 22nd is connected to the frame 21 via the coupling member 31 a pulling force in the direction of the free end 32 of the element 22 exerted on the elements 22, 23, 24, 25 of the slatted frame 20. The element 23 guided in the guide rails 33 becomes this in the direction of the free end 32 of the element 22 in moved horizontally. Through the articulated Connection of the elements 22, 23, 24, 25 are all Elements 22, 23, 24, 25 or joints 26, 27, 28 in the direction of the free end 32 of the element 22 moves. The usual resulting horizontal when pivoting the element 22 Movement component of the free end 32 is thereby compensated. The free end 32 of the element 22 is accordingly when pivoting the same only in the vertical direction moved up and down. In the horizontal direction, however, it is free end 32 of the element 22 is immovable. The coupling element 31 accordingly causes a when pivoting the element 22 Forced displacement of all elements 22, 23, 24, 25 in the direction on the free end 32 of the element 22. This positive displacement is due to the horizontal displacement of the elements 22, 23, 24, 25 allows.

In deviation from the exemplary embodiment shown in FIG. 1 to 8, it is also possible that the coupling members 31 with the End section 34 not on the frame 21, but on another, means that cannot be pivoted relative to element 22 (head element) are attached. So the coupling members 31 with the End section 34 e.g. also on a wall surface, floor surface or be attached to a foot part.

An element, not shown in detail, is used to give away the element 22 Drive. This drive is preferably as Electric motor designed and positioned directly in the joint 26. The drive is able to handle all occurring moments and absorb forces. Accordingly, the coupling members 31 act the forced displacement when pivoting the element 22 of the elements 22, 23, 24, 25 cause almost exclusively a tensile load. All other moments and powers are picked up by the drive. Accordingly, the coupling organs 31 are also referred to as tension members. Just like the joint 26, the joints 27, 28 are not shown in detail Drives assigned to the pivotability of the elements 23, 24 or 24, 25 to each other. That the joints 26, 27, 28 drives each designed as electric motors 3 to 8 is illustrated in that the joints 26, 27, 28 clearly above the elements 22, 23, 24, 25 protrude.

The guide rails 33 have opposite the longitudinal spars 29 of the slatted frame 20 over a slightly inclined course. The Inclination is such that when the Element 22 and thus when pivoting the element 22nd from the inclined position shown in FIG. 1 in the horizontal 2 the horizontal displaceability of the elements 22, 23, 24, 25 is facilitated. Due to the inclined The course of the guide rails 33 accordingly arises Force exerted by moving element 22 down into position 2 the essentially horizontal displaceability of the element 23 in the slightly inclined guide rails 33 facilitated. Alternatively, this restoring force can also be caused by the use of a spring element that when pivoting the element 22 into the horizontal position 2 the horizontal displaceability of the elements 22, 23, 24, 25 supported.

The coupling members 31 can be in different ways be trained. So it is possible that the coupling members 31st are designed as ropes. In this case, the Swiveling the element 22 - ie the head element - in the inclined position exerted a tensile force by the ropes the forced displacement of the elements 22, 23, 24, 25 to guarantee. When pivoting the element 22 in the However, the ropes do not make them horizontal Restoring force transferable. In this case, the provided spring elements already mentioned. Through this when pivoting the element 22 into the horizontal position the forced displacement of the other elements. alternative for this purpose it is also possible to use the coupling members 31 as rods train. When pivoting the element 22 in the inclined The rods in turn exert a pulling force around the position Forced displacement of the elements 22, 23, 24, 25 to guarantee. When pivoting the element 22 in the horizontal position can also exert pressure forces from the bars be exerted to the positive displacement of the elements 22, 23, 24, 25 to effect. In this case, they act as rods trained coupling members 31 accordingly both tensile forces Pressure forces. It is also possible to stand next to the bars to provide the spring elements mentioned so that the rods are almost exclusively exposed to tensile loads.

A slatted frame 38 according to a second embodiment of the 9 to 16 also show the slatted frame shown there 38 has a frame 39 and four articulated interconnected elements 40, 41, 42, 43. Two each adjacent elements 40, 41 and 41, 42 and 42, 43 are in turn connected to each other by a joint 44, 45, 46. The frame 39 of the slatted frame 38 is just like the frame 21 of the slatted frame 20 by two parallel to each other Longitudinal bars 47 and 47 extending transversely to the longitudinal bars Cross bars 48 formed.

The element 40 is in turn designed as a head element that Element 43 as a base element. The elements 41, 42 are concerned in accordance with the already in connection with the slatted frame 20 1 to 8 described buttocks and leg elements.

The elements 40, 41, 42, 43 of the slatted frame 38 according to FIGS. 9 to 16 are horizontally displaceable relative to the frame 39. For this is the element 41 in on the longitudinal bars 47 of the frame 39 fixed guide rails 49 mounted horizontally. With regard to details regarding the design of the Guide rails 49 is on the guide rails 33 of the Slatted frame 20 made according to FIGS. 1 to 8 directed.

The element 40 to be pivoted - ie the head element - is on both sides via a coupling member 50 with the frame 39 connected. The coupling members 50 are for this purpose with a first End section 51 via a first joint 52 with the frame 39 connected. With one opposite the first end section 51 End portion 53 is each of those adjacent to element 40 arranged coupling members 50 via a second joint 54 with the connected to pivotable element 40. To that extent they are Slatted frames 20 and 38 are designed to match. Therefore is also ensured with the slatted frame 38 according to FIGS. 9 to 16, that when pivoting the element 40 a free end 55 of the Elements 40 only moves up and down in the vertical direction while the free end 55 is in the horizontal direction is immovable.

The slatted frame 38 according to FIGS. 9 to 16 differs from Slatted frame 20 according to FIGS. 1 to 8 by the design of the Drive for pivoting the elements 40, 41, 42, 43. During in the slatted frame 20 according to FIGS. 1 to 8 each joint 26, 27, 28 two adjacent elements 22, 23 and 23, 24 and 24, 25, respectively A separate drive is assigned to the slatted frame 38 according to FIGS. 9 to 16, a single drive 56 for pivoting of the elements 40, 41, 42, 43 provided. The drive 56 is preferably designed as an electric motor.

The drive 56 penetrate both in the horizontal direction Sides each have an axis of rotation 57, 58. Each of the axes of rotation 57, 58 carries a lever 59, 60 on each side. The levers 59 serve to pivot the element 40, ie the head element. The levers 60 serve to pivot the element 43, so the foot element.

9 to 16, the levers 59 and 60 are with a first End 61 and 62 attached to the respective axis of rotation 57 and 58, respectively. With ends 63, 64 opposite ends 61, 62 are the levers 59 and 60 with the elements to be pivoted 40 or 43 in contact. The end section 53 of the coupling element 50 and the end 63 of the lever 59 engage the element 40 a common point, namely at the joint 54. In which Joint 54 is therefore a double joint. The Levers 59, 60 can be driven independently of one another by the drive 56 be pivoted.

The coupling members 50 of the slatted frame 39 can in turn be designed differently. It is possible that To form coupling members 50 as a rod or rope. It will refer to the explanations for slatted frame 20 according to FIGS. 1-8 directed. If the coupling members 31, 50 are designed as a rope, so its length is dimensioned such that in the inclined Position pivoted header elements (elements 22, 40) Rope is almost tight.
