Utility model content

It is therefore an object of the present invention to provide a folding bed which folds down to narrow dimensions by means of directional hinge elements incorporated in the frame structure. Another object of the present invention is to provide a bed that is comfortable by means of a helical spring support system.

These and other objects are achieved by a folding bed comprising: a frame having side rails and end rails connected to the side rails; hinges on each of the side rails such that the frame configured to be folded in half with the end rails facing each other; and a flat plate mounted to the end rails and the side rails via springs. The panels are preferably formed from a strong woven fabric, such as canvas. There are a plurality of legs connected to the side rail and configured to fold between an open position in which the legs extend perpendicular to the frame and a closed position in which the legs extend parallel to the frame. A headboard is attached to one of the end rails. The headboard extends perpendicular to the frame in a direction opposite the legs in the open position. There is at least one support element connected to the end rail or the side rail and below the slab.

A locking mechanism is connected to each of the legs to hold the legs in an open position so that the bed cannot be inadvertently retracted when in use. The locking mechanism includes a pin fixedly connected to one of the legs and a locking plate pivotally connected to the frame. The plate has a slot cut therethrough and the pin extends through the slot. The slot has a vertical extension at one end, so pivoting the plate causes the pin to extend through the extension locking the legs in the open position, and pivoting the plate causes the pin to exit the extension allowing the legs to move to closed Location. The pin has an enlarged head wider than the slot so that the pin remains permanently attached to the plate.

There are mattresses that are removably arranged on a flat panel. The mattress is adapted to be folded together with the frame. The mattress may be made of thin foam that is easily folded, or the mattress may be sectioned in the middle so that it can be folded more easily.

Preferably, the support element is made of straps. Straps may extend on either side or between the ends of the frame to support the panel against excess weight. In one embodiment, there are two support elements arranged diagonally to the frame such that the two support elements cross each other.

The legs are arranged in pairs such that each leg is connected to the oppositely arranged leg via at least one crossbar extending between the two legs. In this way, each pair of legs is opened or closed together. Preferably there are two crossbars between each pair of legs. In another embodiment, each pair of legs is formed from a single U-shaped bar with rounded corners at the bottom. In this embodiment, corner supports may be mounted at the corners of the U-shaped bars to prevent the legs from sliding on the floor surface.

The bed of the present invention can be doubled to obtain a double or king size bed by using a second folding bed connected via side rails. The two beds are connected via a connector with snap-fit parts that fit via form fit on the side rails. The snap-fit parts can be easily removed to disassemble the bed.

To hold the mattress in place, there may be at least one texture patch mounted to the deck for gripping the mattress. The textured patch is constructed of hook and loop type fasteners such as ) is formed on one side and the other side of the hook and loop type fastener is mounted to the mattress.

In another embodiment, the mattress has at least one strap extending across one side of the mattress. The strap is adapted to fit around the frame when the mattress is placed on the frame to retain the mattress on the frame.

detailed description

Figure 1 shows a bed according to the invention. The bed comprises a support frame 10 formed by side rails 11 and end rails 12, and folded legs 13 and 13' The legs 13 and 13' arranged on opposite sides of the frame 10 are connected to each other via the connecting fence 14, so that each pair of legs 13 or 13' connected by the connecting fence 14 is folded and unfolded together. For added stability, two connecting rails 14 can also be used. A headboard 15 is connected to one of the end rails 12 and extends in a direction opposite to the direction in which the legs 13, 13' extend. A mattress 16 is placed on top of the frame 10 and supported by a support plate 17 as shown in FIGS. 2 and 3 .

As shown in Figure 2, the frame 10 can be folded into a U-shape by bending the side rails 11 at hinge points 18 and folding inwardly the legs 13 near the end rails, resulting in a compact bed arrangement for storage . The legs 13' located in the middle of the frame 10 are not folded. As explained later with reference to Figures 12 and 13, a locking plate 34 is arranged on each end leg 13 to allow the legs 13 to be locked in the open position or folded into the closed position.

As shown in FIG. 3 , the plate 17 is attached to the frame 10 via springs 18 , completely surrounding the frame 10 . This allows the tablet 17 to move when subjected to the weight of the body and provides a more comfortable sleeping surface. Plate 17 is preferably constructed of a strong woven fabric, such as canvas, although other materials may also be used.

Figure 4 shows the underside of the frame 10 with the legs removed for illustration. Here, a strap 19 is connected to the end rail 12 and extends below the plate 17 . The straps 19 provide additional support to the plate 17 under high levels of pressure so that the springs 18 are not damaged and the plate 17 does not crack. Figure 5 shows an alternative embodiment in which there are two straps 19 arranged diagonally on the frame 10 and crossing each other in the middle of the plate 17 for additional support. Strap 19 may be formed from any desired material, but a strong woven fabric such as canvas is ideal.

As shown in Figure 6, two frames 10 can be placed side by side and joined together to create a double size bed. This connection takes place via a snap-fit connection 22 which snaps onto the side rail 11 of each of the two frames 10 .

As shown in Figure 7, the legs of the frame 10 may also be configured as a single unitary U-shaped structure 21 having rounded corners 23 and an integrally formed bottom span. As shown in Figure 8, corner supports 24 may be attached to the fillets 23 to provide additional support and grip so that the bed does not slide around on the surface.

To hold the mattress 16 securely in place on the frame 10, a texture patch 25 may be placed on the flat plate 17, as shown in FIG. The patch 25 may be made of any suitable material that produces a high degree of friction with the mattress 16 . For example, a rubberized surface with a rough texture or knots may be used. Alternatively, as shown in FIG. 10, hook and loop type fasteners 28, 29 such as - Placed on the support 17 and the mattress 16 such that when the mattress 16 is placed on the flat plate 17 the fasteners 28 , 29 are connected to each other to prevent any movement of the mattress 16 on the flat plate 17 .

In another alternative embodiment shown in FIG. 11, a strap 30 may be attached to the mattress 16 and when the mattress 16 is placed on the frame 10, the strap 30 is placed around the end of the frame 10 to hold the mattress 16 Stay in place. Strap 30 may be elastic to allow for a more secure fit.

Figures 12 and 13 show the leg locking device in detail. A locking plate 34 is attached to each side rail 11 adjacent one leg 13 of each opposing pair of legs. Pin 35 is connected to leg 13 and extends through slot 36 in plate 34 . At one end of the slot 36 is a slot extension 37 that extends perpendicular to the slot 36 . When the pin 35 is placed in the extension 37 , the leg 13 is prevented from pivoting since the pin 35 cannot slide within the slot 36 . This is illustrated in Figure 12, which shows the legs 13 in the locked position. To unlock the leg 13 , the locking plate 34 is pulled upwards, causing the pin 35 to move out of the extension 37 and into the slot 36 . At this point, the leg 13 can be pivoted upwards and the pin 35 is allowed to slide along the slot 36 until the leg 13 is fully folded.
