Mattress with a structure allowing its cover to be taken off

There are known mattress formed of an inner structure provided with springs to which one or more layers of material are secured at the upper and lower sides in order to give the proper softness, rigidity and insulation to both sides of the mattress to be fabricated.

The thus obtained assembly is then covered with the outer mattress slip which is secured to the inner structure of the mattress by strings passing from one side to the other side of the mattress and being secured to the slip by buttons or other grips of pleasant aesthetic aspect. Such a mattress forms one assembly with the outer slip so that the latter cannot be removed for cleaning purposes. To avoid such a limitation, a second cover protecting the inner slip is resorted to.

It would be very practical to be able to remove the slip of the mattress both to avoid the provision of a second slip for hygienic reasons and to clean the covering slip. In order to take the slip off it would be necessary not to secure the slip to the inner structure, thus omitting the connection strings between the two opposite sides of the mattress. Such a solution makes the slip free from the mattress itself but causes the problem that in use the mattress slip moves with respect to the mattress so that the peripheral band tends to twist.

The present finding seeks to provide a solution which allows the slip of a mattress to be taken off and keeps the compact form of the mattress unchanged without causing the mattress slip to shift in use.

Such a solution consists in the provision of transversal cords crossing the mattress from one side to the other side in the transversal and, if necessary, also longitudinal directions and directly secured to the peripheral band.

The present finding will be more readily apparent from the accompanying drawings in which an exemplifying, not limiting embodiment is shown.

Figure 1 shows a mattress provided with covers which are about to be removed and with a cut-away portion to see the interior thereof.

With reference to the figure, the mattress formed of its usual basic construction is provided with cords 1 which cross it in the transversal direction and, if necessary, also in the longitudinal directions at suitable intervals. Such cords are secured to the peripheral band 2 so that they can accomplish the function of handles 3. Both the peripheral band and the lengths of cloth 4 are provided with zippers 5.

Under such conditions, the peripheral band may be secured to the structure of the mattress due to the provision of the transversal cords. Thus it is possible to remove and to put back the mattress slip by using the zippers because it is not secured to the inner structure by the conventional cross strings.

The particular securing means is capable of keeping the mattress slip and the peripheral band in its position without deformation with the use.

In a possible alternative embodiment, the cords may also be secured by strings to the inner surface of both sides of the mattress without forming the outer handles. In the annexed drawing an embodiment relative to a spring mattress is shown but the finding may also be applied to a foamed mattress.

Formal and structural modifications may be applied to the described embodiment, particularly as far as the securing system of the cords to the side band is concerned, without departing from the scope of the present finding as defined in the following claims.
