Description

The present invention relates to a method for adjusting mattresses in an operating position according to the preamble of claim 1 and a mechanism for its execution according to the preamble of claim 6.

For such beds, there is a need to be able to change the user-facing surface. This is to change both the transpiration position and to change the load to which the mattress is exposed, as well as to change the design of a mattress.

In the patent application US 2011/0265269 For example, a device for facilitating rotation of a mattress in a horizontal plane on springs or a platform about a vertical axis is described. This device is equipped with parts which allow the rotation of the mattress about a vertical axis, whereby the head part of the mattress can be exchanged with the foot part and vice versa.

However, this publication does not solve the problem of being able to easily change the top of a mattress with the bottom and vice versa. This option is convenient both to ventilate the mattress and to change the load that is exposed to this side. This rotational movement of the mattress has hitherto been carried out by the user or, for example, in hospitals without aids by the staff.

In the publication DE 846 157 is a rotating device for recliners described with double-sided support of the reclining frame, a standing for the purpose of weight balance under tension of tension springs Nuremberg scissors is provided, which is mounted with its lower hinge on the base of the couch, while their upper joint as a journal bearing for the rotatable lying frame is trained to bring.

As can be seen, the reclining frame must be lifted by applying force to rotate it to a position of the upper joint at a sufficient height to rotate the reclining frame 180 degrees. The scissors themselves are provided with no drive for their movement and can not be locked in the position in which the frame itself must be turned. This rotary device is not intended for bed mattresses which are to be ventilated and placed in a comfortable position for bedding.

The publication GB 2 276 315 discloses a vertically movable bed mounted on a pair of rails which are disposed on a wall via rollers which engage in the rails. The adjustment of the bed is done manually or by a hydraulic drive. At no point in this document is described the property of rotating the bed about its axis by 180 ° for bedding. The installation of rails on the wall of a room is also complicated.

The publication US 2,112,355 describes a lift for beds with rotating means, in and above the Center of the bed, are arranged with discs above the bed and with cables which extend around the discs and take the turning means to promote the bed upwards and so to reverse the bed during lifting.

This document by no means deals with a mechanism for placing a mattress in an operating position, either for bedding, for making the mattress comfortable for a massage, or for leaving it in a bent position.

The Swiss patent CH 172027 Finally, describes a divan with a pivotally supported by the frame mattress, wherein for the support and the guide of the mattress when turning the same on two opposite sides of the divan two rails are provided, which are articulated by means of a respective rotary arm on the frame. The rails are hinged at one end to a common pin of the mattress and the other end is slidably disposed in rectilinear horizontal guides of the frame. The mattress is provided at both the guide rails respectively associated sides with two guide pins, each of which is guided along a guide profile attached to the frame.

In this case, a simple parallelogrammartiger mechanism with two converging into a pivot point of the mattress arms arm extensions, which converge in the direction of the articulation remote from the side of the mattress, where they slide in horizontal guides. To bring the mattress into the position suitable for rotation, this must be done by hand and it is not a stable horizontal position intended for bed making.

The object of the present invention is to make the intervention of the user or the staff when bedding or to set up the mattress when changing the position of the mattress as much as possible by proposing a bed or a mattress with the possibility of it or to place them in such a position as to facilitate 180 ° rotation of the mattress to change the two sides of the mattress itself and to obtain a bed with different functions of sleeping position and massage.

Another object of the present invention is that the interested in massages (doctor visits) person has the cost-effective way to receive in the appropriate rooms, the specialist staff for massages or doctor visits, without having to go for a massage outside the house, and Although in the same bed, where the person usually sleeps (or other random persons), which can also be converted into a massage bed by a mechanism that facilitates the rotation of the bed level.

This object is achieved by a method for adjusting mattresses in an operating position according to the characterizing part of claim 1 and by a mechanism for its execution according to the characterizing part of claim 6.

For bedding or providing the mattress, it is also possible to avoid burdens or damage (trauma) to the spine to bring the bed level to a level that is suitable for their establishment. This is possible with a mechanism from the ground or on a subframe, not shown, the bed grid level. It is also possible to anchor with the bed feet. Not shown is also a storage system in which LED lamps are incorporated with UV rays which, with a suitable capacity, cause the mites damage to their reproductive apparatus, preventing their growth and reproduction, thus giving the possibility of a healthier and better sleep. The "anti-mite" system, referred to for simplicity, is placed between two bars near the bar ends in the form of a pedestal or other known form and the introduction of a low voltage power supply, or with a 220 volt connection or with a different voltage for countries with different ones Introduced standards. The UV rays are not visible in their function, the anti-mite system will therefore be provided with a green indicator light during operation, red indicator light in the off state. It is also possible to equip it with a timer. The anti-mite system may be placed on the rods of the guides or telescoping cylinders or drives, as well as at another location, such as below the louver and slot appropriately machined grid or stave, or may be attached to a stand alone be provided provided container which is arranged on the adjusting mechanism.

In another embodiment, the bed with sleeping function and massage function, these functions can be obtained by a mechanism disposed on the ceiling, from which at least one rope is lowered, at the lower end of a disc is arranged, which connects to the pin, which is pulled out from the inner frame of the mattress and on one side at least has a cable attached, while the other side remains free. The ropes are at the upper ends, that is wound on the ceiling on two winding drums, which expediently in a known manner actuated the unwinding and winding around the disc cause, causing the rotation of the bed level by 180 °, turning the same becomes.

In another embodiment, the cables are lowered from the ceiling over the winding drum, at the lower end at least one rotating mechanism is connected, after reaching the pin of the arranged inside the mattress frame after it has been operated once, after which arranged at the upper end Drum / s on the ceiling up and unwind under raising and lowering of the mattress, wherein the arranged on the lower side mechanism causes by operating the cable cables in a known manner, the pivoting of the mattress by 180 °. After the mattress has been turned, for example, the sleeping side below and the massage side not shown here will be at the top.

The frame located within the mattress has its center in the longitudinal or transverse direction, depending on the way the mattress - head / foot - to be pivoted, or different, it is a pin with rods or screw rings, the rods or operated the screw rings, which are also connected to the movable side of the frame, wherein the same is stiffened. If the pin is not pulled out, then the rods are on the screw ring or on the bolt at rest and the stiffening mechanism of the frame itself is located out of function, wherein the frame arranged within the mattress takes over that of a possibly driven grid in its functions. If the extract of a pin is actuated, so the opposite pin is pulled out, as in a case between two inner sides of the frame, there are two levers which are parallel to the pin axis inclined, connected at their central ends via a third, central lever, pulling out a pin, and consequently also that remote is pulled out, in which case with a new retraction of a pin and the other is retracted, wherein the connected levers are connected at their outer ends with the pins which are pulled out. In another embodiment, instead of the lever, a sheath can be used, within which a cable is arranged, which allows the one and the opposite pin the exit and reentry simultaneously according to the Bowden method. The shell is on the one hand attached to one of the extendable pin and on the other hand clamped to an outer holder of the other pin. At this latter extendable pin the cable is connected, while on the other hand its end is clamped to the outer holder of the other pin. The pins of the inner frame of the mattress may be provided with springs to promote the exit of the pins from the frame.

By means of the lifting and rotating mechanism, the mattress over the inner frame of the same and its bolts is raised to the pivot point of 180 °, wherein it is turned around to then be lowered to the sleeping level or operating level. The pivoting takes place via the Gelenkparallelogramm where a rope or cable is mounted with slot guide, which at the ends of a Washer is fixed, in which a spring is mounted and on which the cable is wound on and fixed at a position of the disc, so that upon rotation of the disc can not make a rotation greater than 180 °, including possibly a not shown, designated attachment point is provided. The rotation can begin as soon as the lower length of the middle of the mattress exceeds by a few centimeters the length of the mattress itself. It is preferred that upon reaching a suitable height, the mattress begins to rotate by narrowing the articulated parallelogram connected to guide rods, telescopic cylinders or drives, thus achieving that of the cable attached to the disc and is connected to the lower part of the Gelenkgleichallelogramms with the guide slot or with another location, is tensioned by the disc itself and the mattress is rotated over its exited from the mattress frame and connected via the joint with the disc bolt by 180 °.

The lifting mechanism, which is connected to the joint via the converging rods, is raised to the height at which it is hooked to the frame bolt. In order to fulfill the function of the anti-shock function and vice versa or anti-reflux, parallel plates are pulled out of the profile frame or grid or board out of pockets, while a further two mutually parallel pockets are at rest and vice versa. By raising the lifting mechanism and connecting the rollers to the arms resting on the plates converging on the plates, the above-described positions are obtained. The support feet are telescopic type with locking and unlock. At its ends is a hinge which converges in a carriage, which is arranged according to the functions on the four parallel sides of the frame or lattice or board profile, which allows the inclination of the grid as desired, the axis thereof at the moment where it is inclined to be a minimum shorter than the rest position. The arms with the cogs or cylinders or rollers, in another embodiment, not at the, at the upper end of the frame or. Grid or board profiles grid may be arranged, but also at the lower end or on the outside thereof, in connection with the plates or other requirements. In another embodiment shown here, these functions can be fulfilled. The arms with rollers or cylinders or rollers are formed by the Gelenkgleichallelogramm forming elements at the upper ends of the wheels or cylinders are mounted and, as mentioned above, both in the upper part of the frame profile extended from the pockets Can cut plates as well as those in the lower part of the frame or grid or board profile. In order to bring the mattress level in the position of the Bettenmachens or operation on the telescopic cylinder, pull-out guides or drives, also levers can be operated in a known manner and plates from the pockets must in one of the further embodiment not shown, the arms with the Cylinders or rollers are pulled out, which connect to the lower part of the frame or to the arranged at the top of the frame plates.

The lifting mechanism can be used in its entirety from both the ceiling and the floor both in the Longitudinal side and the transverse side of the mattress or the bed as well as be arranged on a support pin of the mattress frame.

In the FIG. 1 is the reference numeral 1, a bed according to the invention shown. The bed has in a known manner a frame 2 with not shown grid, which is supported by telescopic feet 3, which are positioned in a known manner at different heights relative to a floor 4. On the front sides of the bed 1, an adjusting mechanism 5 is arranged outside. This consists of guides 6 and 7, in each of which rods 8 and 9 are displaceable, which converge in a hinge pin 10. At their free ends, the rods 8 and 9 are provided with joints 11 and 12 on the floor 4.

On the frame 2, a mattress 13 is arranged, projecting from the center line, preferably longitudinal center line, bolts 14 when they are extended.

On the rods 8 and 9, in their retracted position, in the guides 6 and 7 respectively, are secured substantially at the exit thereof from the guides 6 and 7 arms 16 and 17 which respectively carry rollers or wheels or cylinders 18, which come into contact with plates 119 which emerge from pockets 19 at the top Side of the frame 2 are provided. On the rods 8 and 9 10 rods 23 and 24 are articulated at the same distances of the hinge pin, thus with the rods 8 and 9, a parallelogram is formed.

In the FIG. 2 In a variant, the rods 23 and 24 extend beyond their hinges 25 and 26 to carry at their ends a roller or cylinder 28, the arms 16 and 17 being replaced.

In the FIG. 3 a foot 3 with a telescopic weft 29 is shown to partially indicate the mattress or the bed.

In the FIG. 4 the situation is shown in which from the foot 3, a further telescopic shot 30 is pulled out with the extracted from the pockets 19 interception plates. Thus, the frame is stored on these plates 119 in a stable position to make the bed that is supported by the feet 3.

In the FIG. 5 the rods 8 and 9 are pulled out of their guides 6 and 7, wherein the hinge pin 10 is coupled to the pivot pin 14 of the mattress 13. This position is achieved with the plates 119 retracted in the pockets 19. The mattress 13 is in a vertical position, which will be explained in more detail below.

In the FIG. 6 the extract of the rods or telescopic cylinders or drives and therefore the lifting of the hinge pin is achieved by levers 31 and 32 which are articulated to the base frame 33 and a slot 131 with a pin 132 which projects from the rods 8 and 9, respectively.

In the FIG. 7 a mattress 34 is shown with a massage board 35 which is directed upwards and with the sleeping side 36 down. It is also indicated the inner frame 182 of the mattress. In the FIG. 8 an adjusting mechanism 5 is shown with a massage mattress 35 and drive rods 23 and 24 which move the plates 119 via their rollers or wheels or cylinder 28.

In the FIG. 9 In contrast, a massage mattress 34 is shown with a downward massage plane 35 and arms 16, 17, which move the plates 119.

In the FIG. 10 is another drive of the rods 8 and 9 shown on the levers 31 and 32.

The FIG. 11 shows the adjustment mechanism 5 in the raised position with massage mattress 34 with downward massage board 35th

FIG. 12 equals to FIG. 11 but with an upward massage level 35.

The FIG. 13 FIG. 12 shows an example with a massage plane consisting of a head member 38, a waist member 39 and a bottom member 40 which are interconnected and operable by lifting mechanisms shown herein or actuators 138 and 140, not shown. Inside the mattress, where the massage board rests, except that hinges to the slope of the massage level Are included, holders are provided, which fly up on the grid or frame or board.

The FIG. 14 has a bed in a vertical position of the massage mattress 34.

The FIG. 15 shows a variant with levers 31 and 32 for driving the adjustment mechanism. The FIG. 16 shows the parallelogram, the joints 22 and 10 are connected by a slot guide 41 with each other, with a hinge 22 which is slidable in the slot 41 of the guide. How closer in the FIGS. 17, 18 . 19, 20 and 21 shown, the rods 8 and 9 are articulated with the interposition of a sleeve 44 on the hinge pin 10. The hinge pin 10 extends from one side into a disc 43, around which a cable 42 is wound, which is secured at its free end to the hinge 22. The cable 42 is tensioned at a certain height of the mattress or at a certain angle between the two rods 8 and 9, and with further reduction of the angle, it is the rotation of the disc 43 such that the mattress itself is pivoted.

The bolt 10 conveniently extends into a washer 46 with a wedge 47 which is coupled to the groove of a washer 48 at the end of the bolt 14 which is extendable from a pipe portion 49 fixed to the mattress frame. In order to be able to better guide the coupling between the disk 46 and the disk 48, when the bolt 10 is moved in the direction 110, the disk 48 is expediently aligned by an inviting funnel 45 which extends above the slot guide 41.

This funnel is in the FIGS. 19, 20 and 21 shown in three different views.

The FIG. 22 schematically shows in a diagram a pocket from which the plate 119 comes out.

FIGS. 23, 24, 25 and 26 12 schematically show a side view of a chain or frame 50 in various configurations of the chain or frame (part of the inner frame of the mattress itself, which gives the possibility to rotate the chain or frame members around the hinges 51). Each chain or frame member has pins 52 of the inner frame of the mattress, which engage in slots 53 of each other via joints 55 connected plates 54. The plates 54 are therefore adjustable relative to the chain or frame members and the joints 55 can be brought into alignment with the joints 51. With displacement of the plates 54, the joints 51 and the joints 55 are no longer aligned with each other and the plates 54 make the chain or frame 50 rigid. The mobility of the chain or the frame is in FIG. 28 shown.

The FIG. 29 shows a way the platelets 54 to move over rods 56 which are articulated to a disc or a screw ring 57 and the plate 54 eccentrically. Therefore, when the disk 57 is rotated by a screw 58 which is actuated by extracting or reinserting the bolt in the frame, the chain or frame can be brought from a rigid position to a movable position.

In the FIG. 30 For example, the displacement of the plates 54 over a Bowden cable of known type can be obtained.

In FIGS. 31 and 32 is shown the possibility of the sliding movement of a chain or a frame on that parallel to the chain itself via two levers, which run in each case a slot at one end and each hinged to the other lever at its other ends. FIGS. 35 and 36 show the displacement of the platelets, which are achieved via a Bowden cable.

FIG. 37 shows an adjustment mechanism, which is carried out with at least one cable 59 which depends from the ceiling to wrap on a bolt 60 of a mattress 61. The mattress is raised above a bed base 62. In the Figure 38 the rope is unwound from drums 63 to wind around a disc which is secured to the bolt 60 of the mattress 61. For the rotation of the bolt 60, the cable 59 is fastened via a fastening 65 with the disk 64.

In the Figures 39 and 40 In one embodiment, the mattress 61 is suspended from the bolt via a powered rotating mechanism 66 which hangs on the cable 59.

FIGS. 41 to 44 show a further embodiment in which a group of frames / grids / mattresses is indicated overall by the reference number 67. It is provided in a known manner with extendable feet 68 and therefore liftable in different positions. The feet 68 are located on a subframe or plate 73 or floor 69 and contribute its upper end a frame 70 in which or on which a mattress 71 is arranged, for example, with the interposition of a grid, not shown.

The mattress 71, as already described with reference to the embodiment shown in FIGS. 1 to 6, is provided with pivot pins 72 each of two mutually parallel sides of the mattress 71, for example of the type as in FIG FIG. 18 shown, project. On a platen 73, an adjustment mechanism in the form of a stork beak 74 is arranged.

The cranesbill 74 consists of two rods 75 and 76 hinged together in 77 and of two hinged together in 80 the rods 78 and 79, at the ends in 81 and 82, the ends of the rods 75 and 76 are articulated to form a parallelogram.

The free end of the rod 75 is articulated in 83 to a slider 84 which is mounted in a guide 100 (FIG. Fig. 41 ) is displaceable. With the slider 84 is for the displacement of a spindle 85 in engagement, which is suitably driven by a motor 86, for example electric motor. The rod 76, however, is articulated in 99 on the plate 73.

The rod 79 is articulated at its free end in 82 and the rod 78 in 88 on a support 89. Conveniently, the hinge 88 of the rod 78 is formed by a bolt which is displaceable in an elaborated in the carrier 89 slot 90.

The carrier 89 is provided at its ends with a flap 91 and 92, respectively. The two flaps 91 and 92 are each hinged from a position in alignment with the carrier 89 in a position which is perpendicular to the axis of the carrier 89 such that, as in the FIG. 43 the frame 70 is shown completely or as shown in FIG Figure 42 shown, partially intercepted. This folding movement can be carried out, for example, by means of an electromagnetic system or in another manner, not shown. When intercepting the frame 70 this can be brought by the flaps 91 and 92 either only one of the two in a raised or inclined position in which only one of the two flaps is folded. The various positions are determined by the extract of the telescopic sections 97 and 98 of the feet 68.

The carrier 89 also carries at its center a disc 93 in the manner as shown in the figures of 43 to 45. On the disc 93, a cable or a chain 95 is fastened at its free end to a connection 96 which is fixed to the support plate 73 or under frame 70.

Conveniently, the disc 93 is biased by a spring 94 relative to the carrier 89 of the thread 95 in cooperation between the disc 93 and the bolt 72 and then the mattress 71 is rotated.

In a known manner, the disc 93 is provided with a freewheel to the wedge 47 from FIG. 17 in engagement with the groove of the disc 48 of the bolt 14 in FIG. 18 and the bolt of the Figures 41 and 43 to keep in touch.

Finally, it should be understood that the term "mattress" refers not only to mattresses in the narrower sense, but also to beds, chair beds, or any other objects furnished from one side or the other to a person for both to relax, to sit or for massages or to treat.
