RU2315539C1 - Horizontally inflatable bedding - Google Patents

Abstract

FIELD: furniture industry, in particular, necessities of human life, more particular, transformable furniture.

SUBSTANCE: horizontally inflatable bedding consists of air-impermeable casing with transverse partitions. Rigid plates are attached to lower part of transverse partitions and to zones between partitions, as well as to inner side of casing bottom and sides. Small-sized wheels are fixed to lower part of transverse partitions.

EFFECT: convenient usage, simplified manufacture and provision for quick inflation in horizontal plane of bedding.

Description

The proposed device meets the vital needs of a person and relates to transformable furniture (air mattress, air bed).

A sufficient amount of transformable furniture is currently known. In recent years, marked progress has been noted in the production of various polymer products, in particular this applies to air mattresses that withstand multi-ton loads, are comfortable for sleeping and relaxing, and in a deflated state take up very little space, taking into account the indicated properties of the inflatable products, this device was founded .

The prototype of a horizontal air mattress is an air mattress, which has a rectangular, cross-sectional body of selected sizes, made with upper and lower tiers communicating with each other, bounded by an internal partition and the corresponding walls of this building, and the author provides several options for implementation (see Cl. 7 A 47 C 27/08 (11) US 6568011 BB (22) 0.01.2001 (21) 765487).

The proposed device is a single-chamber rectangular casing made of an airtight material, mainly PVC, with transverse partitions fastened round to the casing, which are rectangular with rounded corners and having rounded openings for free air circulation inside the casing, combined sheets, because . the lower part of the transverse partitions with a height of 2/3 of the entire partition is made of rigid PVC sheets of selected thickness, to which the remaining 1/3 of the PVC fabric is attached. Moreover, the lower rigid part of the partition is attached to the bottom of the case so that it forms a small protrusion between the floor and the bottom, given the fact that small wheels are attached to it to reduce the friction of the bottom of the case against the floor.

Two hard plates are attached to the bottom of the body from the inside end to end with an indent from the walls slightly exceeding 1/2 of the distance between the fasteners of the transverse partitions, which are separated from the transverse partitions, depending on the thickness of these plates, at a distance that allows them to flex inwardly.

In the same way, two rigid plates are attached to the walls of the housing from the inside between the mountings of the rigid part of the transverse partitions.

The main purpose of the rigid plates attached to the bottom and the walls of the housing is to ensure, when the housing is deflated, that the housing parts are retracted between the transverse partitions in one direction, namely inward, and also to ensure stability of the lower housing part. The lower part of the rigid transverse partitions during deflation of the casing provides horizontal folding of the casing.

The fastening of some elements of the housing to others can be carried out by the method of high-frequency welding of polymeric materials described in patent RU No. 2097192 dated 12/27/93 (class B 29 C 65/04), or by another method capable of providing high strength fastening of these elements.

From the end part, the body has two valves: one inlet and one outlet, through which there is a quick pumping and pumping of air, for example, using a household vacuum cleaner. During air injection, the air mattress extends in the horizontal direction, and during air pumping, it decreases in volume also in the horizontal direction, because the lower rigid parts of the transverse partitions when pumping air do not allow the upper canvas of the body to lie on the lower.

If necessary, the inflatable mattress can be made in a two-chamber version, for this it is necessary to attach another panel with holes for free air circulation between the lower part of the mattress with hard plates and the upper soft part.

The aim of the present invention is to provide a convenient, quick-acting, easy-to-manufacture and low-space horizontal air mattress. With the appropriate compressor pump, a horizontal airbed can be built into wall cabinets or serve as a mechanism for transforming sofa beds.

The technical task is to create such an inflatable device, which, unlike all existing at present, when it is inflated and deflated, it unfolds and develops in a horizontal direction, taking in the folded state a strictly defined size. This result is achieved through the use of such structural elements as rigid transverse partitions and rigid inserts in the walls and in the bottom of the device.

Figure 1 shows the inflatable mattress in the working (inflated) state, the places of fastening of the rigid plates on the inside on the sides and transverse partitions are dark colored.

Figure 2 shows schematically two sections of an inflatable mattress, turned upside down, for a visual representation of the places of attachment of the wheels to the transverse partitions and the places of attachment of rigid plates, depicted in the figure in dark color.

Figure 3 gives an idea of why rigid plates attached to the fabric of an air mattress end-to-end to one another bend towards the plate attachment side, i.e. inside the case, but not in the opposite direction.

Claims (1)

A horizontal air mattress consisting of an airtight casing with transverse partitions, characterized in that rigid plates are attached to the bottom of the transverse partitions and between them from the inside, to the bottom and sides of the casing, and castors are attached to the lower part of the transverse partitions.
