Abstract

The beds have a frame (1) which has at least one narrow-wall metal plate (2) on at least one long side. The plate is displaced inwards and its outer surfaces do not project beyond the outline of the mattress (7). The plate is preferably made of aluminium and bent at the corners to form at least part of the foot and part of the head frame. It is attached by bolts to cross beams (8) parallel to the foot and head frames. A mechanism at the base allows the frame to be displaced horizontally and to be adjusted in height.

Description

The invention relates to a bed frame for pairs side by side to one Double beds that can be put together according to the generic term of Claim 1. Such a bed frame is known from US-A-4,524,471.

In the hotel industry, it is desirable to equip hotel rooms with two beds, that stand together once and thus form a double bed and once apart two single beds result in a high occupancy rate to reach the room. The problem here is the two beds in the to bring the standing position as a double bed so close together that the two mattresses merge almost seamlessly. This is it is known to dispense with a bed frame so that the mattress is loose lies on the slatted frame. The disadvantage here, however, is that it becomes a "Walking" the mattress can come on the bed frame.

Also known are single beds with a wooden frame for lateral edging of mattresses that stand side by side as a double bed release between the mattresses.

The object of the invention is to provide a bed frame that both secure and stable mounting of the mattress on the bed frame as well as one almost seamless transition of the two mattresses in the standing together Position enabled.

The inventive solution according to claim 1 provides a narrow-walled Metal plate to use for the bed frame, at least on the Long sides of the bed frame as far as the floor plan of the mattress is concerned is set in that its outer surfaces do not over the Mattress floor plan protrudes. This will make it safe with simple means Fixation of the mattress in the bed frame achieved, as this fits the Metal plate is held. Since the metal plate is narrow-walled and with their outer surfaces not protruding over the mattress floor plan, come across at Moving two beds together to form a double bed, the outside of the mattress together, so that a continuously continuous top Lying surface is created.

The bed frame shown schematically in Fig. 1 comprises a bed frame 1, which consists of two narrow-walled metal plates 2, which at the corners are bent and together two side frame parts 3, a foot frame part 4 and form a head frame part 5. The bend will make it sharp Edges avoided in the corner areas, which is a source of danger in particular could represent when moving the bed. The metal plates 2 exist preferably made of aluminum, because this makes a bed frame with a small Dead weight is attainable. In addition, they have a surrounding bead or the like to achieve the necessary strength. The frame parts 3,4,5 delimit a recording area 6 for receiving a in FIG. 2 shown mattress 7. Fig. 2 shows that the frame 1 about a third of the Height of the mattress 7 encloses so that its lower area between the Metal plates 2 is clamped and its upper area the width of the Towering over metal plates 2. When joining two beds into one Double bed touch the mattresses and a gapless Transitional area has been created.

As is apparent from Fig. 4, the bed frame comprises two cross members 8, on which the metal plates 2 are releasably fixable. This is a central structural element created on which the other elements of the bed frame are held are. On the underside, two support feet 9 are in each case on the cross member 8 Screwed or the like. Attached to the mattress 7 from the floor distance. Furthermore, the feet 9 are on the underside with rollers 10 connected, since this makes moving the bed frame easier.

To move the bed frame, the cross members 8 with a Moving device 11 connected, the quick assembly or Moving the two beds apart possible. Especially in It is important to hospitality industry to have a device available that a compilation or spreading of the allows two beds, as this can be done by a housewife should, so that for economic reasons the time and effort required for this should be minimal. In addition, there should be any traces on the carpet be minimized by moving the beds. An illustration of the different Positions when the two are moved apart or moved together Beds by means of the displacement device 11 is illustrated in FIG. 3.

2 shows, the displacement device 11 consists of a on the floor fixed base 12 and a support 13, on the one hand opposite the base 12 from a set position to a shift position of the bed is vertically displaceable and on the other hand with the cross member 8 horizontally slidably connected. By shifting the height of the Bed the effort to move the bed frame is considerable reduced. The height shift of the bearing 13 is determined by a Fig. 6 shown eccentric 14 allows that against a bottom the bearing 13 presses and the bearing 13 during its rotational movement moves vertically. The eccentric disc 14 is mounted in the base 12. As in 5 is shown in more detail, the base 12 consists of two half-shells 15, which are fixed to each other by screwing. Limit you on the inside a receiving space 16 which is used to support the eccentric disk 14 and for vertical guidance of the support 13 is used.

6 and 7 show the eccentric disc 14 by means of a drive 17 set in a rotational movement, the drive 17 from a smaller one Gear 19 and a larger gear 20, which mesh, the smaller gear 19 serves to drive the larger gear 20, which in turn drives the eccentric disc 14. As from FIGS. 10 and 11 emerges, the small gears 19 of the two displacement devices 11 of the two cross beams 8 connected to each other by a shaft 21, so that a coupled movement of the two shifting devices 11 given is. Fig. 12 shows that a hand crank 22 can be placed on the shaft 21 with which the two small gears 19 can be driven mechanically. It is however, it is also conceivable that the two gears 19 are electrically driven become.

Furthermore, FIGS. 7 and 8 show that the bearing 13 with a continuous, inserted guide pin 23 is provided, the on both sides in a vertically aligned slot 24 in the half-shells 15 of the base 12 engages. To wear the elongated holes 24 in the Half shells to prevent 15 and better management of the To allow guide slide pin 23, the slots 24 are with pressed through guide flanges 24a reinforced on the edge. The end can Support 13 each has a roller 25 for connection to the cross member 8 take up. As is apparent from Fig. 9, the cross member 8 is on one long side formed as a roller rail 26 so that the rollers 25 of the support 13 Can accommodate roller rail 26. To ensure safe roller guidance of the rollers 25 to ensure the support 13 on the roller rail 26 is on the Support 13 each provided a securing element 27 that the Roll rail 26 of the cross member 8 engages.

To the bed frame from the double bed position shown in Fig. 3 too individualize, the small gears are first by means of the hand crank 22 19 rotated, which in turn over the large gears 20 the eccentric 14 set in a rotary motion. The eccentric disc 14 presses against the Bottom of the support 13 and moves it vertically upwards. Here is the support 13 by its guide slide pin 23, which in the Elongated holes 24 slides securely in the receiving space 16 of the base 12 guided. Due to the upward movement of the support 13, the bed frame placed in an inclined position. Now the bed frame on the bed 13 opposite side raised to a floating position spent and the cross member 8 are sliding over the bearing 13 postponed. After the desired distance to the other bed has been reached, the bed is put back on the other side of the floor. Then the support 13 is moved down again by means of the drive 17, so that all four feet 9 of the two cross members 8 are again in contact with the ground to have. The rollers 10 of the feet 9 allow a sliding and Soft installation on the floor, so that any traces of grinding on the Carpet are minimized. The cross members 8 are each with a stop at the end 28 for the support 13 in the form of one piece with the cross member 8 connected, downwardly projecting flag so that a defined end position is specified. Overall is through this Sliding device 11 only a small effort to move the Bed frame required, so that, in particular, a housewife automatically Can make the beds move.

As FIG. 13 shows, the metal plates 2 serve to delimit the receiving area 6 attached to the cross beams 8 for receiving the mattress 7. To one enable straight design of the outside of the frame 1, have the cross members 8 recesses 29, while both side frame parts 3rd are provided with inwardly projecting tongues 30, which in the recesses 29 of the cross member 8 can be suspended. The tongues 30 are with the Cross members 8 screwed inside so that a firm connection to the Cross member 8 is guaranteed. With this type of attachment there are none externally protruding screw parts or the like. Visible, which in particular is important if the frame 1 is provided with fabric.

14 is a fabric covering 31 for covering the frame 1 illustrated. For this purpose, the lower edge of the frame parts is provided 3,4,5 each to be provided on the inside with a Velcro strip 32. Furthermore the frame parts 3, 4, 5 can be glued with a felt or nonwoven material 33 be before a fabric 34 is applied to the frame 2, so that a Relining is given. The fabric 34 of the fabric covering 31 is of this type cut so that it surrounds the frame parts 3,4,5 overleaf. On his the lower edge also has a circumferential Velcro strip 35, which is connected to the Velcro 32 on the frame parts 3,4,5.

After attaching the Velcro strips 32, 35, the fabric 34 is around the frame 1 struck around and extending along the frame parts 3,4,5 Profile strands 36 hooked. For this purpose, the upper edge of the fabric 34 has a Fastening piping 37 sewn, which gives him sufficient final strength gives. The profile strand 36 is provided with a recess 38 such that he can take up the piping 37. In addition, the profile strand 36 a further recess 39, which is complementary to locking lugs 40 on the Cross beams 8 and the frame parts 3,4,5 is formed and for mounting the profile strand 36 on the cross member 8 and the frame parts 3,4,5. Around to prevent the profile strand 36 from slipping, he will also with a plug 41 attached to the cross member 8. As is apparent from Fig. 16, points the cross member 8 has a plurality of bores 42 which are at different intervals related to the cross member edge are set. Since the distance of the Profile strand 36 of the side frame part 3 depending on the thickness of the selected material 34 varies, can therefore the optimal mounting position be determined. In Fig. 15, this different spacing of the Profile strand 36 shown.

In order to provide the entire frame 1 with the fabric covering 31 provided at a corner of the frame 1, for example in the area of Head frame part 5 to begin and then all the way around the sheet-like fabric 34 to tension the frame 1 and by means of the Velcro fasteners 32,35 fasten until the second corner of the head frame 5 is reached. Then the Fabric 34 folded over the frame 1 and onto the piping 37 of the fabric 34, the profile strands 36 are placed. The profile strands 36 of the Side frame parts 3 are fastened by the mentioned plugs 34. For Attachment of the profile strand 36 in the foot or head part area is in each case U-shaped trained tension wire 43 is provided, the profile strand 36 against the foot frame part 4 or head frame part 5 presses. As shown in Fig. 17, the Tension wire 43 in turn attached to the cross member 8. So all in all achieved safe and easy connection of the material 34 to the metal plates 2.

Provision can be made for the fabric covering 31 all around the bed frame 1 to tension including the head frame part 5. However, it is also conceivable not to frame 1 in the area of the head frame part 5 with fabric string as this is usually on the wall and one instead separate, not shown headboard with, for example, ornament-like Design. This head part can be in corresponding recesses be hung in the head frame part 5 of the bed frame. In addition to the described fabric covering 31, it is also conceivable that made of aluminum manufactured metal plates 2 to be distinguished by a special design, so that a fabric covering can be dispensed with.

To lock the two beds in the double bed position enable, locking means 44 are in each case on the cross members 8 at the ends intended. These locking means 44 advantageously consist of a Locking profile 45 into which a downward locking pin 46 can be snapped. The locking profile 45 is attached to the fixed bed while the locking pin 46 is connected to the movable bed. The locking profile 45 is designed in such a way that it allows different locking positions Depending on the selected thickness of the fabric covering 31. At the Vertical movement of the bed through the support 13 becomes the locking pin 46 pulled out of the locking profile 45 smoothly, so that the locking is solved. Furthermore, a variable attachment of the Locking means 44 may be provided to differently designed To be able to use metal plates 2. When spreading the beds in the single bed position, the locking profile 45 can be pivoted backwards, so that it is out of sight.

Overall, a bed frame is created, in which the mattress is secure is supported and at the same time when putting together two single beds a double bed a gapless transition area between the two Mattresses is given. In addition, the sliding device a quick and easy to move together or apart of the two beds, which is particularly important in the hotel area It is important because here the use of a room as a double room and than a room with two single beds, the occupancy rate is one Hotel rooms can increase significantly. The fabric covering of the metal plates made possible, for example, by choosing different fabrics rest of the room decoration adapted design of the bed frame.
