Description

The present invention relates to a transport assembly and to a bed constructed of a transport assembly.

The hospital and nursing beds considered here preferably comprise a plurality of electrical drives in order to adapt the bed to the wishes of the patient and / or a desired care task, as will be explained in detail later. Such beds are u.a. used in the private environment, which means that they are simply brought to the site and there must be easy to build. For transport, it is advantageous if it (ie in the transport position), the space required is as small as possible. The same requirement also applies to the use in retirement or nursing homes, as well as in hospitals. In the latter fields of application is added that beds are kept in reserve, so that for this reserve the smallest possible space requirement is desired.

For this reason, there are beds that are easily dismantled and convertible into a transport assembly in which the mattress supports are arranged vertically and the heads are as close together as possible. The rolls of the bed are used in this transport assembly, as well as in the built bed, so that these known transport assemblies are easily pushed. As explained in the explanation of the prior art, components, e.g. Transport clips, used only for the transport assembly.

The object of the present invention is to provide an improved transport assembly which is easily convertible into a bed without special tools. Special parts, which are only needed for transport, should be avoided if possible. In particular, the transport clips have the problem that they are easily misplaced or lost. And since the transport clamps are specially manufactured and absolutely necessary parts, a disassembly of the bed with the conversion into a transport assembly is then no longer possible.

The stated object is solved by the features of the independent claims. Preferred embodiments are subject of the dependent claims.

A transport assembly for a bed comprises a head-side main and a foot-side main, which are aligned in a transport position parallel to each other, further comprising at least one mattress support member which is aligned in the transport position with its mattress support surface parallel to the heads. Both heads are starting from the transport position via a bearing point pivotally relative to each other and / or directly against each other slidably mounted. The footprint of the transport assembly is less than half the footprint of a built-up bed. The term main refers to the use of the part on the bed. The transport assembly preferably comprises all parts which form the bed with the mattress support surface. Other parts, such as motors, and / or controls may but need not be part of the transport assembly, and are preferably not or only partially. The mattress is preferably not part of the transport assembly. The heads are preferably designed such that in the position of use of the bed, the upper edge of the head is at least 30 cm above the mattress support surface, so the top of the mattress carrier or is arranged. Said "immediate displaceable mounting of the heads to each other" means that parts or portions of the heads, which are rigid and preferably one piece part of the respective main, are mounted directly against each other in the form of a guide. In the prior art referred to in this document, in contrast, at least one transport clasp is required, which causes an indirect displaceability of the heads. An advantage of the described concept is that the ergonomics of the construction is significantly increased. Namely, the transport assembly can be wound or swung open and thereafter located between the heads components can be easily removed.

It is advantageous if the heads can be brought into an open position in which at least one mattress carrier part can be removed from the transport assembly and this mattress carrier part can not be removed in the transport position of the transport assembly. In this open position are the parts that make up the bed frame form, preferably in a vertical position. Thus, a kind of package is created in which the heads are outside and the heads provide as storage for the intervening parts. This arrangement is particularly advantageous since the rollers of the bed are arranged on the heads and so also on the outside of the transport assembly, which ensures the stability of the transport assembly against falling over. The mattress carrier parts are preferably vertically aligned in the transport position. If the lying surface is spanned, for example, by two mattress support parts, preferably at least one of the mattress support parts is arranged between the heads and the other mattress support part can also be arranged between the heads or alternatively connected from the outside to one of the heads, such as being suspended.

In particular, the heads may be pivotable relative to each other. In this case, the bearing axis of the pivoting can be aligned vertically. This orientation is considered on a horizontal surface on which the transport assembly stands. The main surfaces of the heads are perpendicular. This is advantageous because the movement can be carried out without special force application (without lifting).

Preferably, the transport assembly can be brought into a closed position, which is also referred to as transport position, in which the or the mattress support member (s) is arranged between the heads / are. Preferably, the heads are arranged parallel to each other. Alternatively and / or additionally, this or the mattress support part (s) is aligned vertically with its lying surface. As a result, a compact design is obtained.

In particular, the heads are locked in the transport position against each other, thereby preventing said pivoting or sliding movement.
The locking is also possible by a screw connection. Preferably, the locking means are captively connected to the bed. At least a holding device is preferably provided for the locking device, with which the locking device can be fastened to the bed when the lock is open.

Furthermore, pivotable frame longitudinal struts can be attached to the heads, wherein a bed frame of a bed which can be built from the transport assembly can be produced via a connection of the frame longitudinal struts. Thus, the frame longitudinal struts each only a part of the length of the bed frame and are therefore easy to transport. And the overall height of the transport assembly is not so high that it is no longer subject to e.g. Doors would fit.

The transport assembly preferably comprises exactly one integral mattress support part, which may in particular comprise a plurality of mutually pivotable sections and which forms when used on the bed, ie in the position of use of the bed, extending over the entire bed surface of the bed mattress support surface. In other embodiments, for example, two mattress support members can be used, which together form the mattress support surface extending over the entire bed. In this case, by means of frame longitudinal struts, a bed frame can be formed and / the mattress carrier / can at least partially rest on the bed frame. Preferably, a mattress carrier center part, on which a mattress carrier head part and mattress carrier foot part are mounted, rest on the bed frame, or be firmly connected to it.

In particular, the head-side main and the foot-side main may each comprise two rollers, which serve both for pushing the transport assembly, as well as a bed which can be created by the transport assembly.

Furthermore, it is advantageous if the transport assembly does not comprise special parts which are only used to form the transport assembly and are not required in the subsequent use of the bed. As a corresponding special part is in particular a part understood, which includes attachment areas for attachment of the bed heads to him, so that over this, the transport assembly is formed. Cable ties, as well as wires or tapes, which are used to fasten different components or foils or cardboard are preferably not understood as special parts of the above understanding, as this particular none exclusively for this purpose manufactured parts are. Likewise, for example, foam moldings are not understood as such special parts.

Furthermore, in the case of the transport assembly, the mattress support part (s) is preferably provided with a guide with respect to exactly one associated main part, and the guide can be overcome to remove the mattress support against the force of gravity. In this case, either the guide can preferably be made possible by attaching the mattress support part into a region of the main or by placing the mattress support part on a corresponding contact surface of the main. There are no positive locking means needed for the removal of the mattress support member.

1. a) motorische Höhenverstellung des Betts,
2. b) motorische Neigung des Bettrahmens für bevorzugt eine Fußtiefstellung,
3. c) motorische Winkeländerung der Rückenlehne und
4. d) motorische Winkeländerung der Oberschenkellehne.

Dabei kann das Bett mindestens drei der vorgenannten Antriebe aufweisent und es sind bevorzugt sämtliche vier Einstellarten motorisch vorgesehen. Der Begriff "motorisch" ist hier weit zu verstehen und umfasst auch hydraulische, pneumatische, Antriebe und kann bspw. über Schrauben- oder Schneckenantriebe realisiert werden.The bed considered here preferably has motor drives for at least two of the following four functions, namely:

1. a) motorized height adjustment of the bed,
2. b) motor tilt of the bed frame for preferably a Fußtiefstellung,
3. c) motor angle change of the backrest and
4. d) Motor angle change of the thigh rest.

In this case, the bed can have at least three of the aforementioned drives and it is preferably all four types of adjustment provided by motor. The term "motor" is to be understood here broadly and also includes hydraulic, pneumatic, drives and can, for example, be realized via screw or worm drives.

A bed may comprise a head-side main and a foot-side main, both heads are arranged in a transport position so close to each other that between them not the bed surface of the bed spans and both heads starting from the transport position via a bearing point relative to each other and / or are directly against each other.

It is advantageous if in the connection of the main with the frame longitudinal struts, a first releasable fixation and a second releasable fixation is provided, wherein the two releasable fixations are constructively designed differently. In particular, the first releasable fixation may be designed for forces during construction and the second releasable fixation may be designed for forces during use of the bed.

In the Fig. 1 shown exploded view of a transport assembly of the prior art comprises a head-side main 10 and a foot-side main 20. There are rigidly and inseparably connected to the heads 10, 20 connecting shafts 11 and 21, which can be inserted into corresponding hollow profiles of transport clips 50 and 51, such as it is indicated by the arrows. Thus, a block is provided which has a high rigidity as a transport assembly, so that it can be easily moved over the rollers 70 as a unit. The transport clips 11 and 21 comprise further shafts which point upwards and into which a mattress carrier head part 30 and a mattress carrier foot part 40 can be inserted. In addition, the transport clip 51 comprises a pipe socket, in which the bed frame 9 can be inserted. Thus, the transport assembly comprises four main components, the heaviest parts by weight being referred to as the main component. The Matatzenkopf- and -fußteile 30, 40 are separate parts, which are each plugged separately into the transport clips 50, 51. In addition, these parts must be secured with cable ties. To construct the bed, the individual parts are removed after cutting the cable ties and constructed so that the outer frame parts of Matatzenkopf- as -fußteils with the corresponding connections 11, 21 are connected. In addition, the mattress carrier parts 30, 40 are connected to one another via a plug-in section 31. The Matatzenträgerfußteil is preferably in two parts with a narrow area which serves as a buttock support and is rigidly connected to the bed frame and starting therefrom a movable area which is anwinkable as a backrest.

Unillustrated fasteners, such as screws, provide a firm cohesion to the mattress carrier center portion 35 in the thus assembled bed. In addition, the transport bar 50 includes a rectangular bracket which serves to receive side rail spars (not shown) so that the side rail spars are also part the transport assembly are.

After assembly of the bed, the transport clips 50 and 51 are no longer needed. In various cases, the customer will erroneously dispose of the transport clips 50,51 with other packaging material such as foils, cable ties or foam parts. In other cases, the transport cleats 50, 51 are cleared away by the customers in places "good" that they are no longer findable later, when the bed is to be picked up again. In these cases, it comes with the desired removal of the bed to serious problems, since it can not be brought into the transport position. Rather, the items of the bed must be individually packed, moved and loaded. This can lead to damage and also the logistical effort is much greater than when moving the rollers provided with transport assembly.

In contrast, the preferred embodiment of the invention explained below, in addition to other advantages explained below, does not involve transport clasps. In Fig. 2 the bed is shown in the transport position 1. On the outside, rollers 70 are shown, which are fastened in pairs to the head or foot-side main 10 and 20, respectively. At the heads 10, 20 directed in the direction of the bed interior connecting webs 11, 21 are formed having a bearing point for the head-side frame longitudinal struts 12 and the foot-side frame longitudinal struts 22 at a free end. The frame longitudinal struts of the respective main 10, 20 are with strut connectors 13, 23 (see Fig. 5 ) stiff connected to each other, so that these frame longitudinal struts in each case in unison around the bearing point relative to the connecting shaft 11, 21 are pivotable. These frame longitudinal struts 12 and 22 are therefore always parallel to each other.

On each of the sides of the transport assembly 1, which later form the longitudinal sides of the bed, latches between the frame longitudinal struts 12, 22 are provided which comprise a locking bolt 29. In the FIGS. 6 and 7 this lock is recognizable in detail. The head-side Rahmenlängsstrebe12 includes a holding sleeve 18 and the foot-side frame longitudinal brace 22 comprises two retaining sleeves 28 which are collinear in the transport position, so that a locking bolt 29 can be guided through them, whereby the frame longitudinal struts 12, 22 are fixed relative to each other. At the upper end of the locking bolt 29, a handle is formed, which is color-coded, so that it is recognizable to the user as a functional part. The grip is as in Fig. 7 clearly visible, connected to the frame longitudinal strut 22. This connection also includes a Maximalwegbegrenzung, so that the locking bolt 29 is preferably only so far pulled out that it is no longer in engagement with the retaining sleeve 18, but especially with one of the retaining sleeves 28 in contact. Thus, the locking bolt 29, as well as the handpiece captive and / or inseparably connected to the frame longitudinal strut 22 (and the bed). In comparison of the Fig. 6 With Fig. 7 It can be seen that in the latter there is a small distance between the two frame longitudinal struts 12 and 22. This indicates that the heads now, as in the lower part of the Fig. 4 shown, are pivotable relative to each other. As a swivel bearing serves a storage on the opposite longitudinal side of the bed, which is comparable to the previously described connection with the components 18, 28 and 29.

In this way, the transport assembly is hinged, as in Figure 3 and 4 is shown. By unfolding, the distance of the rollers 70 increases, so that the tilt stability of the transport assembly 1 further increases. In this position, an assembly can be removed, which comprises a mattress carrier head part 30, a mattress carrier center part 35 and a mattress carrier foot part 40. The said head and foot parts 30 and 40 are pivotally mounted on the central part 35. In addition, two hooks 33 are integrally formed on the mattress support foot part 40 by means of of which this assembly was mounted on the head-side strut connector 13. Against lateral displacement, this module is protected by being received in the transport position in the transverse direction of the bed between the frame longitudinal struts 12, 22. This results over the prior art, the advantage that it is secured against slippage, so that can be dispensed with further fasteners, such as cable ties. In contrast, in the prior art described, the parts of the mattress support were only inserted into sockets of the transporting clips 50, 51, which required additional fastening.

If the said assembly of the mattress support has been removed, it can be unfolded, as in Fig. 5 is shown. In this state, the mattress carrier has the same size as a mattress to be used and serves to support the mattress. In addition, in this figure, the state is shown that the frame longitudinal struts 12, 22 are pivoted down perpendicular to the respective heads. Via plug-in sections 31, the frame longitudinal struts 12, 22 are inserted into one another, so that they thereby form the bed frame. Now the mattress carrier 30, 35 and 40 can be placed on this bed frame. For this, the mattress support center part 35 comprises in the transverse direction of the bed projecting areas, which lie on top of the bed frame. Alternatively, the mattress support center part 35 can rest with a recess on the strut connector 13 in a form-fitting and / or displaceable manner. With fastening means, not shown (eg a screw), the mattress support member 35 is attached to the bed frame. This connection or screw connection can be a combined connection, which also ensures that the frame longitudinal struts 12, 22 are fixed relative to one another in the bed longitudinal direction. The Matatzenträgerkopf- and -fußteile 30, 40 are not attached to the bed frame. Rather, electrical drives (not referred to in detail) are provided to effect a head elevation by angling the mattress carrier head portion 30 or the thighs / legs by angling the mattress carrier foot portion 40. The drives used may preferably be supported on the bed frame and / or the respective main.

In order to give the transport assembly 1 sufficient stability, is according to Fig. 8 in the pivotable mounting of the frame longitudinal strut 12, 22 relative to the respective main 10, 20 provided a releasable attachment, which blocks the mobility of the frame longitudinal strut 12, 22 relative to the main 10, 20 in the folded-up position. Since the two frame longitudinal struts of each main 10, 20 are coupled in pairs to each other via the strut connectors 13, 23, only one such blockage is sufficient per main. The blocking can, for example, as in detail of Fig. 8 shown to be configured as a push button 15, which is spring-assisted pressed into a blocking position and is releasable against the spring force. In addition, a second blocking position 19 is shown, which comes into engagement when the frame longitudinal struts are perpendicular to the main. This considerably facilitates the construction of the bed.

The process of constructing the bed from the transport assembly 1 is as follows: First, existing protective films are removed. The following is at the in Fig. 2 shown position of the locking bolt from the locking position, in which two frame longitudinal struts 12, 22 of the same bed longitudinal side are rigidly coupled to each other, are pulled, as compared in the 6 and 7 becomes clear. Subsequently, the transport assembly 1 is opened, as it Fig. 3 shows, and the hinged mattress carrier, comprising the mattress carrier head, middle and Fußfuß, 30, 35, 40 can be removed. In addition, the four side rail spars 60, which each pairwise form a side rail on each longitudinal side of the bed, can be removed. Hereinafter, the second locking device which is in Fig. 4 only slightly visible, since it lies behind the frame longitudinal struts, solved.

As already mentioned, this second locking device is largely identical to the aforementioned locking with the components 18, 28 and 29. But the colors of the grips of the locks may be different, so as to better explain the handling order to the user. The second lock limits the movement of the frame longitudinal struts 12 and 22, as well as the heads 10 and 20, in the three Cartesian directions of movement, as well as in two associated directions of rotation except for the third direction of rotation, which is aligned about the vertical axis. Now, when this second lock is released, the heads 10, 20 are separated from each other. Now, in detail A of the Fig. 8 shown locking the frame longitudinal struts 12, 22 relative to the main 10, 20 solved as explained in the explanation of Fig. 8 has been described, so that the frame longitudinal struts can be pivoted in an orientation perpendicular to the heads. In this position, at least in the alternative, a locking relative to the associated main body 10, 20 is provided for each of the frame longitudinal struts 12, 22. This lock can be designed as a screw 16, as in Fig. 6 is shown.

Below you can see the in Fig. 5 be shown two halves of the bed connected to each other. At this time, the side rails will be mounted. For this purpose, vertical slots are formed on the inside and the outside of the bed. These slots serve as guides for sliding blocks, each having two protruding bolts (not shown). These bolts engage in the end blind holes of the side rail spars 60, which in Fig. 3 are shown.

Subsequently, the mattress carrier 30, 35 and 40 is used. Since tilting moments are exerted on the mattress carrier center part 35 when using the bed, preferably the mattress carrier center part 35 is positively connected to the frame of the bed, such as e.g. screwed.

In addition, the motors for the adjustment drives of the bed must be mechanically and electrically connected during the assembly process. The bed preferably has automatic drives for the functions of adjusting the angle of the backrest, which was also referred to above as the mattress carrier head part and the thigh rest, ie for the adjustment of the angle between the mattress support center part 35 and the mattress support foot part 40. In both heads 10, 20 is a drive 72nd integrated, with a telescopically movable portion of the main, on which the bed frame is mounted, is height adjustable. Thus, both the lying surface height of the bed set, as well as a Fußtieflage of the bed.

In Fig. 9 a variant of the invention is shown in which all the components are identical, but it is on both sides of the bed on the locking mechanism of the components 18, 28 omitted with the locking bolt 29. Instead, at the two heads guide portions 14a, 14b arranged, which allow a guide, preferably in bed longitudinal direction. These guide areas may have a rectangular profile 14a, which is adapted with respect to the inner cross section to the outer cross section of a second rectangular profile 14b, which is integrally formed on the other main of the bed. In this way, no pivoting, but a sliding movement is performed in the construction of the transport assembly 1.
