Description
A bed with adjustment of the location angle of its frame together with its mattress relative to vehicle floor
The subject of the invention is a bed with adjustment of the location angle of its frame together with its mattress relative to floor of a vehicle, especially a truck or a caravan (camper).
In the course of a ride in vehicles of that type, there are large bow and stem movements, as well as rolling movements, especially on road bends and mountainous routes, which deteriorate the comfort of getting rest on beds constituting standard equipment of these automobiles. Therefore, there is a need to improve the comfort of persons using such beds.
The problem is partially resolved by an air suspension bed known from patent description No. EP 0407912 A2 which relates to an air suspension platform for bedding useful in moving vehicles such as trucks. The bed comprises an elongated rectangular upper frame with a spring-and-wire bottom to support a cushion or mattress for sleeping. U-shaped mounting members are fixed to bottom portions of both ends of longer sides of the frame and joined detachably with two analogous suspension units which comprise a frame-shaped rectangular upper housing positioned loosely on an identical rectangular lower housing, both housings being reversed respective to each other by 180°, whereas frames of both of the two housings provided with bottoms have, on their opposite ends, three rectangular vertically oriented walls joined with each other and thus forming U- shaped profiles, whereas between the bottoms of the housings there are connecting members with airbag actuators fixed in them allowing to rise either left or right end of the rectangular frame of the bed together with its mattress. Moreover, to one of longer sides of upper frame of the bed, within easy reach of an individual lying thereon, two valves are mounted and connected by means of three elastic conduit allowing to control air pressure in both of the two airbag actuators to which the other lower ends of conduits are connected, while the third one is connected to the truck engine compressor unit. Depending on weight of the user and the required inclination of bed used for sleeping or having a rest, the user uses the valves to regulate pressure in airbag actuators as a result of which, the unit
suspended in the upper housing comes out and up of the lower housing and thus rises one end of the upper frame together with mattress provide in it, i.e. depending on the user’s needs, rises either left or right end of the rectangular frame. However, despite availability of such function, an inadequacy of the bed consists in lack of possibility to change the angle of inclination of its rectangular frame together with mattress placed in it along its left or right longer side.
From patent description US 4196483 known is also a portable mattress support adapted to be readily installed and removed from a confined space and especially in an automobile vehicle cab sleeping quarter area, permitting the absorption of various forces without imparting the same to the user of the mattress. The mattress support (carrier) has a rectangular elongated frame constituting its basis of the and another rectangular auxiliary frame disposed above the first one, central portions of the frames being coupled with each other by means of a cylinder capable to be filled with a fluid under a control of a fluid supply system provided with valves. Moreover, between the two frames, pivoting lever mechanism were mounted transversally relative to longitudinal axes of the frames and a weight responsive means to react to weight of the user of bed mattress, connected with the means controlling a valve regulating flow of fluid to the cylinder. The valve controlling means allow to introduce a determined quantity of fluid to the cylinder in order to move the auxiliary frame away from the lower frame to a selected position as determined by the user.
The objective of the invention is to improve the structure of a bed constituting a piece of equipment of vehicles by developing a new, versatile, and compact structure of such bed, eliminating inconveniences of solutions known to date, by providing a solution enabling to both keep the bed self-levelled in the course of ride and additionally, adjust the angle of placement of the bed mattress relative to automobile floor in arbitrary axis of the bed, as desired by the user, at either positive or negative angle, depending on situation of the road.
The essential feature of the bed with adjustment of the location angle of its frame together with its mattress relative to vehicle floor according to the invention consists in that it comprises an upper subassembly in which one longer side of rectangular upper frame of said assembly provided with a mattress is joined pivotally two supports oriented perpendicularly to the opposite longer side of a rectangular lower frame fixed in a lower subassembly, whereas the two frames, at their half-length, are provided with a manual screw-and-lever mechanism, or both of the two of opposite shorter sides of the frames are equipped with a manual pawl-and-ratchet mechanism, and additionally, the rectangular lower frame of the upper subassembly is fixed in a grid-shaped slate bedstead of a rectangular frame of lower subassembly, in which lower surfaces of both of its two longer sides are provided only with actuators setting in motion the frame together with the upper subassembly or are provided in actuators and at least one fixed supporting element lower end of which is joined detachably with the vehicle floor.
It is favourable when the manual screw-and-lever mechanism comprises a rotary screw both ends of which are bearing-mounted in two coupling pieces situated opposite to each other and attached to both of the two longer sides of lower frame of the upper assembly, and a nut screwed onto the screw and provided with a stirrup joined pivotally with one end of the lever the other end of which is joined pivotally with upper end of the second lever, the second lower end of which is joined, also pivotally, with lower crosswise beam situated at half length of both of the two longer sides and joining the sides with each other. Upper ends of the two levers are joined pivotally with each other and with a slide placed in a guide provided in lower surface of one of the longer side of the upper assembly frame.
It is also favourable when the manual pawl-and-ratchet mechanism is a toothed element with the profile of an annular segment attached by means of a pivot to upper side of the upper assembly rectangular frame engaged with a pawl fixed in a sleeve-shaped housing containing a slidable bar pressing the spring against the pawl, which, together with the housing, are situated on a support fixed to the shorter side of rectangular lower frame of the upper subassembly.
It is further favourable when the employed actuators are pneumatic cylinders or hydraulic cylinders or electric actuators or airbag actuators or single-ended lever mechanisms and moreover, when the actuators are coupled pivotally with rectangular frame of the lower subassembly and with the vehicle floor.
It is similarly favourable when the actuators used as servo elements are connected with a controller attached to one of longer sides of the lower subassembly frame, with the controller being connected, by means of medium-supplying conduits, with each of the actuators and with a compressor and further, by means of an electric conductor, with the inclination level compensation system.
It is also favourable when the servo elements in the form of single-ended lever mechanisms comprise two electric motors joined with each other by means of an arm, whereas each of the upper electric motors is joined pivotally with respective longer sides of the lower subassembly frame, and each of the lower electric motors is joined pivotally with the vehicle floor, while all the motors are connected, by means of electric conductors, with a controller. The controller is connected with the inclination level compensation system by means of one electric conductor, and with an electric power supply by means of a second electric conductor.
Moreover, the subject-matter of the bed with adjustment of the location angle of its frame together with its mattress relative to vehicle floor according to the invention is also characterised in that the bed comprises an upper subassembly situated directly on vehicle floor, with one of longer sides of the upper rectangular frame fitted with a mattress being joined pivotally with two supports oriented perpendicularly to the opposite longer side of the rectangular lower frame, whereas said upper subassembly is provided, at half of its length, with a manual screw-and-lever mechanism or both of the two opposite shorter sides
of each of the two frames are equipped with a manual pawl-and-ratchet mechanism.
Application of the solution according to the invention enables adjustment of the inclination angle in the course of ride in an automobile within much wider range, including adjustment in several axes, the feature being unavailable in solutions known to date in which the inclination angle adjustment was possible in one axis only. Moreover, the use of an inclination level compensation system coupled with a controller and individual servo devices allowed to ensure smooth and fast adjustment and inherent positioning of the bed in the course of vehicle ride in real time allowing to maintain the levelled position in the course of riding uphill or downhill, improving this way the resting comfort of the user, whereas application of an additional mechanism for manual adjustment of inclination angle of the bed mattress, independently of the inherent levelling mechanism of the bed, enables adjustment of the mattress inclination angle according to individual needs of the user and adjustment of the bed inclination angle in the course of vehicle stopovers.

Example 2
The bed according to the second of its embodiments presented in Figs. 8-10 has structure identical to this of the bed according to the second of its embodiments shown in Figs. 1-7, and the difference between the two variants of the bed consists only in that in the bed according to the second of its embodiments, the rectangular elongated frame 29 of the lower assembly 3 is provided with three pneumatic cylinders 31 connected with said frame by means of ball joints 32, and further with a single cylindrical support 40 joined, by means of a ball joint 41, with lower wall of longer side 33 of frame 29, said support replacing one of the four pneumatic cylinders 31 described in Example 1.
Example 3
The bed according to the third of its embodiments presented in Fig. 11 has also a
structure identical to this of the bed according to the first variant of its embodiment shown in Fig. 1-7, and the difference between the two variants of the bed consists in that that the bed according to the third version of its embodiment, the rectangular elongated frame 29 of the lower subassembly 3 is provided with two pneumatic cylinders 31 joined with said frame by means of ball joints 32 and further provided with two cylindrical supports 40 situated opposite said joints at the other end of the frame and joined with said frame by means of ball joints 41 with lower walls of both of the two longer sides 33 and 34 of the frame 29.
Example 4
The bed according to the fourth of its embodiments presented in Fig. 12 has the structure identical to this of the bed according to the first and the third version of its embodiment in Example 1 (Figs. 1-7) and in Example 3 (Fig. 11), and the difference between these variants of the bed consists only in that the bed according to the fourth variant of its embodiment is equipped with one pneumatic cylinder 31 only joined by means of a ball joint 32 mounted at half-length of lower wall of the shorter side 42 of the frame 29.
Example 5
The bed according to the fifth of its embodiments presented in Fig. 13 and Fig. 14 has also the structure similar to this of the bed according to the second variant of its embodiment shown in Figs. 1-7, and the difference between the two variants of the bed consists only in that both of the two longer sides 33 and 34 of the frame 29 of the subassembly 3 of the bed are quipped with two single-ended lever mechanisms 43 each, said mechanism changing the level of the frame along one of longer sides 33 or 34 and/or towards shorter sides 42 or 44 of the frame. Each of the single-ended lever mechanisms 43 comprises two electric motors 45 and 46 connected with each other by means of an arm 47, whereas the electric motors 45 are joined by means of ball joints 48 with longer sides 33 and 34 of the frame 29, and electric motors 46 are coupled, by means of articulated joints 49, with the vehicle floor 7, whereas all the motors are connected, by means of electric conductors 50, with a controller 35 which in turn is connected, by means of electric conductors 38 and 52, with an inclination angle compensation system 6 and with an electric power supply 53, respectively.
Example 6
As it has been presented in Figs. 15-20, the bed with adjustment of the location angle of its frame together with its mattress relative to vehicle floor according to the sixth of its embodiments comprises also an upper subassembly 1 fitted with a mattress 2, a lower subassembly 3 with a lower frame 4 of an upper subassembly 1 fixed in it, and an air compressor 5 and an inclination level compensation system 6 attached to the automobile
floor 7, whereas both the upper subassembly land the lower subassembly 3 comprise functionally interrelated components analogous to those described in the first example embodiment of the bed shown in Figs. 1-7. The difference between the two structural solutions of the bed consists only in that in this sixth example embodiment of the bed, the screw-and-lever mechanism 16 used to change position of the upper frame 8 by means of two levers 23 and 25 joined pivotally with each other and with the frame as well as with the mechanism was substituted with a manual pawl-and-ratchet mechanism 54, and pneumatic cylinders 31 are replaced with four two-segment airbag actuators 55 arranged analogously as in the first variant of embodiment of the bed (Figs. 1-7) with a controller 35, an inclination level compensation system 6, and an air compressor 5. The two-segment airbag actuators 55 are placed directly on the automobile floor 7, and their upper offsets 55' are fixed in sockets provided in lower surfaces of both of the two longer sides 33 and 34 of the frame 29 of the lower subassembly 3. Moreover, in this variant of the bed, a toothed bar 57 having the profile of annular segment is attached to the shorter upper side 13' of the rectangular frame 8 of the upper subassembly 1 by means of a pivot 56, said bar being engaged with a pawl element 58 fixed in a sleeve-shaped housing 59 containing a slidable bar 60 pressing a spring 61 against the pawl, said components together with the housing being placed on a support 62 fixed in shorter side 10' of the rectangular frame 4, said elements constituting a manual pawl-and-ratchet mechanism 54 locking a position established by the bed user at a positive or negative angle of the upper rectangular frame 8 together with the mattress 2 placed on the frame.
Adjustment of level of the bed described in examples 1-6, including its mattress 2 relative to floor 7 in the course of the automobile ride occurs automatically as the automobile floor inclination level is red off by the inclination level compensation system 6 which transmits corresponding signals to a controller 35 controlling operation of a compressor 5 and individual actuators of a type selected from pneumatic cylinders 31, airbag actuators (55) and single-ended lever mechanisms (43). By supplying an appropriate quantity of medium to individual servo elements enables levelling of the mattress 2 in real time and setting it continuously in horizontal position in the course of the vehicle riding on a bumpy terrain.
Example 7
The bed according to the seventh of its embodiments illustrated in Figs. 21-29 with manual crank-driven adjustment of position of its mattress 2 relative to floor 7 of a vehicle, as opposed to the bed in its first version described in the first of its example embodiments (Figs. 1-7), has only an upper subassembly 1 equipped with a screw-and-lever mechanism 16 coupled with a manual crank 17, whereas the subassembly comprises an elongated rectangular upper frame 8 with a grid-shaped slate bedstead 9 constituting a substrate for a mattress 2 placed on it, and a analogous rectangular elongated lower frame 4 situated under said upper frame, whereas in two comers of the lower frame 4, fixed are two vertically
situated supports 11, upper ends of which are joined, by means of hinges 12, with lower surfaces of comers of the upper frame 8. Moreover, both of the two frames 8 and 4 of the upper subassembly 1 are provided, at half of their lengths, with crosswise oriented beams 14 and 15, respectively, to which a screw-and-lever mechanism 16 is fixed and coupled with a manual crank 17, said mechanism comprising a rotary screw 18, both ends of which are bearing-mounted in two coupling pieces 19 situated opposite each other and attached to both of the two longer sides 10 of the lower frame 4, with one end of the screw being coupled with a manual crank 17. Further, a nut 20 screwed onto the rotary screw 80 and provided with a coupling piece 21 is joined, by means of a pivot 22, with one end of a lever 23, the other end of which is joined pivotally, by means of a pivot 24, with upper end of the second lever 25, the other end of which is joined, also pivotally by means of a pivot 26 mounted in a U-shaped stirrup 27, fixed to the lower crosswise beam 15 of the frame 4, whereas both of the two ends of levers 23 and 25 joined with each other pivotally by means of the 24 are also mounted in a U-shaped stirrup 28 of the upper crosswise beam 14 of the frame 8. The bed user, by turning manually the crank 17 in clockwise or counter- clockwise direction, makes the screw 18 of the screw-and-lever mechanism 16 rotate and the nut 20 move along the screw which results in a change in the angle between levers 23 and 25 joined pivotally with each other and with the nut, as a result of which the mattress 2 together with the upper frame 8 is being raised and set at a positive angle, e.g. 10°, or moved towards the automobile floor 7.
Example 8

Moreover, in two comers of the lower frame 4, two vertically oriented supports 11 are fixed upper ends of which are joined, by means of hinges 12, with lower surfaces of comers of the upper frame 8.
Further, in this variant of the bed, a toothed bar 57 is attached to the shorter side 13' of the rectangular frame 8 of the upper subassembly 1 by means of a pivot 56, said toothed bar having the profile of an annular segment engaged with a pawl element 58 fixed in a sleeve-shaped housing 59 containing a slidable bar 60 pressing a spring 61 against the pawl, said components together with the housing being mounted on a support 62 fixed in one side 10' of rectangular frame 4 of the lower assembly 3, said elements constituting a manual pawl-and-ratchet mechanism 54 to lock the upper rectangular frame 8 together with mattress 2 placed on it established by the user of the bed in position characterised by a desired inclination angle.
In further example embodiments of the bed according to the present invention, hydraulic
actuators or electric actuators were alternatively employed as servo elements, also joined pivotally with lower horizontal walls of both of the two longer sides 33 and 34 of the rectangular frame 29 and with the vehicle floor 7.
