Description

The invention relates to a pivotable bed frame with tilt-adjustable bed surface according to the preamble of claim 1.

in the In 2000, the US scientists Sydney Ross Singer and Soma Grismaijer published a book "Get it up! The authors have shown in numerous studies that the usual horizontal flat sleeping position in bed in civilized countries not only leads to poor quality of sleep, but also after a long time diseases such as migraine, Alzheimer's disease, glaucoma, sleep apnea, stroke, impotence and cause or cause similar diseases.

In a comparison of these findings with those of Hecht et al. [2011] and those mentioned by Kuklinski [2008, 2006] are very similar.
Singer and Grismaijer [2000] argue that the above-mentioned diseases are caused by lying flat during sleep in the zero-gravity field. As a result, more blood is transferred to the head and thus into the brain. The increased intracranial pressure generates z. For example, chronic migraine. This can be prevented when the head is stored high. That is, when a sleeper is guaranteed. Among other things, the two authors examined 100 patients with chronic migraine who were sleeping in beds with a tilt of the body between 10 ° -30 °. They achieved that the patients became migraine-free in a relatively short time. This effect is said to have occurred even in patients who suffered from migraine for over 20 years. Even persistent sinus congestion, dry mouth and nasal mucosa disappeared.
According to the sources in their book, the authors are good connoisseurs of space medical literature and express that the findings of this medical discipline have shown them the way to their research on slanting sleep.

A bed frame for slanting sleep, for example, with the subject of DE 20 2012 008 199 U1 known. The bed frame disclosed herein shows in a known manner a plurality of connected frame parts, such as a headboard, a footboard and two side panels.

The frame parts of the bed frame further include corresponding supports on which a slatted frame or the like can be placed, on which then the actual bed surface is placed in the form of a mattress or the like.

A preferred material for the production of such a bed frame is for example wood, the frame parts are made of several wooden boards.

Other materials can be used for the production of such a bed frame, for example, the bed frame can be made of metal parts, plastic parts or a combination of several different types of materials.

It is generally known to make the lying surface adjustable. In particular, bed frames with adjustable head part or foot part are used, so that the lying surface in the region of the head or feet can be brought into a deviating from the horizontal angle.

In various fields of application, such as in the medical field, but also in the private sector, it is desired or necessary to allow an adjustment of the entire bed surface obliquely to the horizontal position.

In the by the DE 20 2012 008 199 U1 document shown, it is provided that the side cheeks of the bed frame curved standing surfaces have, wherein preferably each of the bottom facing the underside of the side cheeks is formed as a curved surface.

Through this arch surface, it is now possible to tilt the entire bed surface at an angle to the horizontal and fix with stabilizing elements in a desired tilting position.

The disadvantage of this bed frame is the relatively high risk of injury in the area of the arched footprints. Here, the weight of a complete bed rests on only two relatively small, ground-side footprints, which, depending on the load of the bed this tends to tilt strongly. This tilting is favored by the structural leverage effect, so always act large forces in the footprint.

So it can come in unprofitable use of the bed frame to an entrapment of body parts, because the tilt-adjustable functional parts are freely accessible.

From these disadvantages of the prior art results the task of designing a tilt adjustable bed frame so that it is possible to tilt and fix the entire lying surface in a simple and safe manner obliquely to the horizontal position.

The solution to this problem is solved in that now in a bottom-fixed bed frame another frame is pivotally mounted about the horizontal axis, which is adjustable and detectable depending on the desired inclination of the bed surface.

By this inner frame, which is pivotally mounted in the outer frame, the risk of injury in the adjustment of the angle of inclination of the arranged in the inner frame lying surface is now minimized. There is no longer the risk of a user adjusting the bed surface puts his hand or another body part in a moving part of the bed frame.

The inventive design of the bed frame also unintentional release of the pivotal parts is excluded.

In addition, the adjustment of the inclination angle is easy to execute even for inexperienced users.

In a further embodiment of the invention, it is provided to incorporate the bed frame according to the invention in a double bed. For this purpose, a rail is mounted centrally between the head and foot of the fixed, outer bed frame, said rail has a receptacle for each there on one side engaging horizontal pivot axes on the right and on the left bearing side. Thus, it is possible to mount two bed frame according to the invention in an outer, comprehensive bed frame, wherein in each case to support the rail receives the inwardly facing axes of the pivot bearing.

In addition, to protect the user flexible and elastic slats, e.g. made of rubber or other flexible cover elements are secured in the movement space between the inner and outer frames, which prevent intervention in the gap and thus injuring the user.

To set the desired pivot angle, a screw is inserted through in the region of the inclination adjustable part of the inner frame, which engages after passing through the inner frame in a thread of the outer frame. For this purpose, it is provided that in each case at the foot as the head end are provided with a plurality of threaded holes, so that different inclination angle can be adjusted.

In an analogous manner, any locking means may be arranged on the outer frame, which engage in associated receptacle on the tilt-adjustable part of the inner frame.

For this example, wood screws can be used. But it can also be other screws, such as metal or plastic screws or other locking means used.

The invention is not limited to screws, it is also possible to use more adjustment and locking elements for adjustable and lockable connection of the outer and inner frame.

For example, pins can be inserted through the inner frame, or it is located in the outer frame two opposite, horizontally aligned bolts whose bolt-side end protrudes into the pivoting range of the inner frame.
In the inner frame a downwardly directed swivel bracket is arranged, which has a plurality of receptacles for the bolts according to the principle of inclination adjustment of the head part of a garden lounger, so that depending on the pivotal position of the swivel bracket different inclinations of the bed are adjustable.

To limit the inclination pads are provided in the fixed bed frame in the region of its head part and in the region of the foot part, which serve as a boundary surface for the pivotable inner frame. Thus, the inner frame rests in a horizontal position on at least two bearing surfaces in the region of the head part of the fixed bed frame.

Now, if the inner frame is pivoted maximum, so that the foot area is immersed in the outer frame and in return the head area comes up, the inner frame abuts in the region of the foot on the foot side pads, which prevent exceeding a certain angle of inclination and in addition for stability of the tilted inner frame to care.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

• FIG. 7 : Perspective view of the tilted inner frame

FIG. 1 shows a perspective view of the bed frame 1 according to the invention, wherein an outer frame 2 with four feet 13 on the floor 21 is. On the head part 14 of the outer frame 2, an elevated head portion is mounted, which can be designed differently depending on the customer or can be omitted in a reduced design of the bed. The outer bed frame 2 also has a foot part 34, which is like the head part 14 with the feet 13 on the floor.

In the outer frame 2, an inner frame 3 is arranged, which has a smaller dimension than the outer frame and is also formed as a rectangle. In this case, the invention should not be limited to a rectangular outer frame and a rectangular inner frame, it can also be used other shapes, such as a square outer frame and inner frame or other geometric shapes, such. As ovals, ellipses or polygonal shapes.

The inner frame 3 is connected to the outer frame 2 via a horizontal axis 12. This axis 12 is arranged in the central region of the side part 32 of the outer frame 2 and is also connected to the side part 33 of the inner frame 3 in the central region. By means of this axle suspension, it is possible to pivot the inner frame 3 vertically in the direction of rotation 5 via the pivot point 4 located in the axis 12.

When pivoting in the direction of rotation 5, the head part 14 lifts in the direction of arrow 7 upwards and the foot part 34 lowers against the direction of arrow 6 down. Contrary to the direction of rotation 5, the head part 14 lowers in the direction of bearing 7 down and the foot part 34 rises in the direction of arrow 6 upwards.

During these pivoting operations, the complete inner frame pivots about the pivot point 4 and thus forms a base for an adjustable lying surface, which can be placed in or on the inner frame.

When reaching the maximum lowering of the foot part 34 against the arrow 6, the inner frame 3 applies to the supports 16 in the inner periphery of the outer frame 2 in the region of the foot part and thus limits the inclination angle of the inner pivotable frame. 3

Now, if the inner frame 3 is pivoted about the pivot axis 4 in the opposite direction of rotation 5, so that the head part 14 lowers against the arrow 7 against the ground, upon reaching a horizontal position of the inner frame 3, a further lowering of the head part 14 by the pads 15th limited in the inner circumference of the outer frame 2 in the region of the head part 14.

Between the two boundaries, the support 15 and the support 16, it is possible to set and fix different inclination angle of the inner frame. For example, at least one screw which acts in the area of the head part or in the region of the foot part serves for fixing purposes.

In addition, a support rail 11 can be seen in the inner frame 3, on which, for example, a spring element in combination with a mattress can be placed. This support rail is fastened, for example, to the side parts 33. An attachment to the head parts and foot parts is provided in a further embodiment of the invention.

In FIG. 2 If one sees the position of the support 15 in the region of the head part 14 and the support 16 in the region of the foot part 34.

The axis 12 may also deviate from the central position of the side part 33 and, for example, be arranged closer to the head part 14, so that the pivot point 4 of the axis 12 is arranged in this area. An approach to the foot part is possible, depending on the load, a different tilting behavior affects a favorable positioning of the pivot axis.

For fixing the inner frame 3 on the outer frame 2, a screw connection is preferred. However, the invention is not limited to a screw, so all other compounds are claimed as essential. The drawings show only an embodiment of the invention, wherein for fixing a screw 8 is inserted through a designated hole 20 in the head part 14 of the inner frame 3 and at the outlet of the hole 20 on a befindliches in the outer frame 2 thread 17 and is screwed into this ,

Likewise located on the foot part 34 of the outer frame 2 corresponding to the thread 18 into which a cross-section at the foot 34 through a hole 19 screw 9 engages.

The threads 17, 18 are preferably slightly offset one above the other and thus allow a fixation of the inner frame 3 in a desired pivot position. The superimposed threads are arranged in a circular path, so you the screws 8, 9, which, due to the inclusion in the rotating around the pivot point 4 bed frame, also move on a circular path, record depending on the pivot position.

The invention should not be limited to two superimposed threads, the arrangement of one or more than two threads per head part 14 or foot 34 is provided. In addition, the threads can be arranged either only in one side part 33 or in both side parts 33.

Such pivotal positions are in FIG. 3 to see. The starting point is assumed to be a horizontal 25. In this initial position, the inner frame lies flat in the outer frame 2, so that the head part 14 and the foot part 34 each have the same distance 22 from the bottom 21.

Now, if the inner frame 3 is pivoted against the pivoting direction 5, this rotates about the pivot axis 4, so that an opening angle 26th between the horizontal 25 and the now new orientation of the inner frame 3 sets. At a maximum pivot angle 26, the foot part 34 is located at a maximum distance in position 23 from the bottom 21st

Now, if the inner frame 3 is pivoted in the pivoting direction 5, this rotates about the pivot axis 4, so that an opening angle 27 between the horizontal 25 and the now new orientation of the inner frame 3 sets. At a maximum opening angle 27, the head part is maximally removed in position 24 from the bottom 21st

In FIG. 4 the inner frame 3 is shown in a horizontal position relative to the bottom 21. The inner frame 3 rests on the support 15. For the fixation of the inner frame 3 in this case only the screws 8 in the head part 14 are required.

In addition, more screws 9 can be used in the foot part 35 for fixing.

In this position, the support rail 11 is located at a distance 22 from the ground, this distance 22 is the same size at the head part 14 as at the foot part 34. On the support rail 11 fixed in the inner frame, a spring element 31 is placed. This spring element is, for example, a slatted frame on which a mattress 28 is then placed.

FIG. 5 shows a tilted inner frame 3, which is pivotable at an angle 27 deviating from the horizontal 25. In this case, the foot part 34 tilts in the direction of arrow 6 and the head part 14 in the direction of arrow 7. In this position, the inner frame 3 rests on the bearing surfaces 16 in the foot part 34. To fix this position engages the headboard a screw 8 in the thread 17 and also engages a screw 9 on the foot part in the thread 18. However, the invention is not limited to that foot and head screws act, it is sufficient in this case that only one side the screws are engaged.

However, the arrangement of at least two superposed threads 17 a and 17 b or 18 a and 18 b, engages, for example, at position 23, the screw 19 on the foot part 34 in thread 18 b and the screw 18 on the head part 14 in thread 17 a.

In FIG. 6 a corner of the outer frame 2 is shown, which stands on the foot 13. The outer frame has a support 16 on which rests the inner frame depending on the pivot position. To fix the respective pivot position serve the threads 18a and 18b, which are located in the side part 32.

In FIG. 7 is a partial perspective view of the bed according to the invention shown. The inner frame 3, which is pivoted about the pivot point 4, now has an inclined against the foot part 34 lying surface. Such a lying surface, which is formed from a mattress 28 and a spring element 31, rests on the support rail 11 in the inner frame 3. In addition, adjustments are still provided on the support rail 11 to allow adjustment of a spring element. In this embodiment, the screw 8 engages through the support rail 11 and a hole 19 located behind it through the inner frame.

The lying surface 28, 31 can be formed by any conditions. For example, may be placed on the side support rails 11, a spring frame, a slatted frame or a support for a box spring mattress.
