Centrally arranged legs for box mattress

Background

When a box mattress consisting of a mattress, a number of lamellae and a frame is to be elevated from the floor, it is required that legs or runners are mounted on the frame of the box mattress. It is not possible to mount the legs elsewhere than on the frame as it would deteriorate the support of the box mattress and the lying comfort. In order for the box mattress be stable, the legs are to be mounted at the comers of the mattress, and the runners are to be mounted at the ends of the mattress. The support of the box mattress in the shape of runners or legs will therefore at all times be secured to the outer frame of the mattress and support the mattress around the corners

Today, much focus is on interior decoration and hence also the decoration of bedrooms, where box mattresses are often used. The existing methods in the shape of runners or legs for elevating a box mattress relative to the floor limits the development and the options available for the interior decoration of the bedroom due to the fact that the legs of the box mattress have to be secured on the frame of the box mattress to obtain stable support. It is a trend within the field of interior decoration to create light and open spaces. Legs arranged at the corners of a box mattress and secured to the outer frame of the mattress counteract this trend due to the legs causing the bed to seem to be a heavy and dark piece of furniture. Moreover, the legs or runners form a dark and confined space underneath the bed.

The dark and confined space delimited by the legs and runners moreover constitutes a good habitat for dust mites which constitute a major problem to humans suffering from dust mite allergy. Cleaning underneath the bed may remedy this problem, but often the existing legs make the cleaning process difficult and hence the cleaning quality deteriorates.

It is a further drawback of the existing legs for box mattress that there is a risk of persons moving about and around the mattress accidentally kicking the support of the mattress. This may result in major damage to that person's feet, in particular due to the fact that the bedroom, where a box mattress is most frequently used, is a room in which the persons often walk around barefooted.

It is a further drawback of the existing legs and runners that, over time, the box mattress is deformed to the effect that it deflects centrally. This is due to the persons using the box mattress often sleeping centrally on the mattress, and consequently the mattress is exposed to the weight influences deforming the mattress centrally. The result is that the longevity of the mattress deteriorates.

Object and description of the invention

It is the object of the invention to solve the above problems and this is accomplished in providing:

A support for a box mattress, said box mattress comprising at least one mattress, a number of lamellae and a frame, and wherein the support comprises at least to attachment devices adapted for attachment to the frame of the box mattress and at least one mounting device arranged within the frame of the box mattress and adapted for attachment of legs, whereby the legs can be attached elsewhere than on the frame of the box mattress. Hereby the advantageous aspect is provided that legs can be mounted within the frame of the box mattress due to the support being attached to the frame of the box mattress and hence it supports the box mattress. At the same time the legs can be mounted to the mounting implements of the support, which implements are arranged underneath the frame of the box mattress.

This means that the support and the legs can be adapted to each other to the effect that the support of the box mattress becomes very stable and that the box mattress is in static equilibrium when sitting on a plane face such as eg a floor.

According to a further embodiment at least one of the legs is/are inclined relative to the vertical. This means that the legs can be arranged centrally underneath the box mattress without the box mattress becoming instable when used. This is accomplished due to the support and legs absorbing the loads to which the box mattress are exposed in use.

According to a further embodiment said mounting implement is arranged centrally underneath the box mattress. Hereby deformations centrally of the box mattress are avoided as it is hereby supported centrally.

According to an embodiment at least one part of the support is constructed from steel or iron which means that the support and legs can be constructed from a material which is very durable and able to tolerate heavy loads.

Besides, the invention relates to a box mattress comprising at least one mattress, a number of lamellae and a frame and further comprising a support as described above. Hereby the same advantages as those described above are obtained.

The invention also relates to a use of a support for a box mattress as described above. Hereby the same advantages are obtained as described above.

The invention also relates to a method of attaching legs to a box mattress, wherein said box mattress comprises a mattress, a number of lamellae and a frame, and wherein said method comprises attachment of a support to said box mattress. Said support comprises at least two attachment devices

adapted for attachment on the frame of the box mattress and at least one mounting device arranged within the frame of the box mattress and adapted for attachment of legs. Said method further comprises an attachment of legs to said mounting implement. Hereby the same advantages as those described above area accomplished.

DESCRIPTIONS OF EMBODIMENTS

Figure 1 illustrates an embodiment of a support (101 ) for a box mattress according to the invention, seen from above. In this embodiment, the support has four attachment implements (102) that are adapted such that they can be secured to the frame of a box mattress, eg by means of a bolt and nut assembly. Each attachment device is connected to a centre plate (103) via a carrier arm (104). On the centre arm, mounting implements (105) are provided to which legs can be mounted. The mounting implements can be one or more holes, fittings or flanges to which the legs are adapted to be

mounted, eg via bolt and nut assemblies. By such support, it is possible to mount legs on a box mattress elsewhere than on the frame of the box mattress due to the attachment implements being secured in the frame and by means of the carrier arms, and the centre plate supports the box mattress. Thus it is possible to mount the legs on the centre plate and hereby it avoided that they are mounted on the frame.

Figure 2 illustrates how the support shown in Figure 1 can be attached to the underside of a box mattress (201). Figure 2a shows the underside of the box mattress with the support in mounted state, and Figure 2b shows the box mattress, seen from the side. The box mattress comprises a mattress (205), a number of lamellae (202), and a frame (203). The four attachment implements (102) of the support are attached to the frame (203) of the box mattress where legs or runners are usually mounted on the box mattress. On the centre plate of the support, four legs (204) are mounted to the mounting implements (105) of the support. The legs are mounted such that they point approximately out towards the corners of the box mattress. By this construction the box mattress is very stable while simultaneously the legs are within the frame (203) of the box mattress.

Figure 3 illustrates how the attachment implement (102) of the support can be secured to the frame (203) of the box mattress. Figure 3a illustrates a section of the inner side of the frame, and Figure 3b illustrates a cross- section through the frame. Uppermost on the frame, a number of lamellae (202) are provided that support the mattress which is arranged on top of the lamellae. In this embodiment, the attachment implement (102) is welded to the carrier arm (104) of the support and is configured as an angle hinge (301) which is secured to the frame via a bolt (302) and a nut (303). The attachment implements can also be configured by drilling a hole in the carrier arm and clamping it in place directly to the frame by means of bolts and nuts. The shown advantage provides the advantage that the carrier arm is moved away from the frame and is hence concealed underneath the box mattress.

Figures 4-7 illustrate further embodiments of the support according to the invention. In each Figure the box mattress is illustrated seen from below (Figure a) and seen from the side (b). In the embodiment shown in Figure 4, the centre plate (103) is arranged underneath the one end of the mattress, and legs of different lengths are mounted to obtain static equilibrium for the box mattress. In Figure 5 the support (101) is configured with two centre plates (103), each of which is arranged underneath their end of the box mattress, and vertical legs are mounted on the mounting implement of each centre plate. In this embodiment, the legs are, as opposed to existing methods, arranged within the frame and not on the frame. Figure 6 illustrates how the invention can be configured with three legs (204) that are all mounted on the centre plate and are arranged such that, between them, they cause the box mattress to be in static equilibrium when sitting eg on a plane floor. In Figure 7 each leg consists of three support bars (701 ) that are welded onto a leg plate (702). Two legs are welded onto each leg plate, and the leg plate is mounted securely to the mounting implement of the support by means of bolts and nuts (703). The three support bars on each leg cause the bed to be very stable.

The shown embodiments are examples of how the invention can be configured and are non-limiting to the invention, the skilled person being able to construct other embodiments without departing from the scope of the invention.
