MXPA06001805A - A foldable mosquito-free patio - Google Patents

Abstract

Foldable patio mainly consisting of mosquito net that - supported by a frame structure - forms the roof and three of the walls. The frame structure may be hinged at the foot of an outer wall forming the fourth wall of the patio. In folded condition the mosquito net is rolled up on an horizontal and two vertical rolls mounted on the outer wall. Un- and up-folding of the structure may be done manually, by means of motors or hydraulic piston-cylinders. By supplementing the sheet of mosquito net with sections of sun-tight, respectively rain-tight cloth, the structure also may protect against sun, respectively rain. By means of hinges the outermost end of the bottom frame may be made turnable if necessitated by narrow space conditions.

Description

FOLDABLE MOSQUITO FREE COVER DESCRIPTION BACKGROUND AND CAPITyPE OF THE INVENTION The mosquito net is normally used to cover windows and doors or in places where the network encloses a place to sleep that can be lifted during the day when it is not necessary. In the present invention the network is used as walls and roof in a cheap roof structure which in effect extends the rest area, work and possibly the sleeping area of the house, and can be bent against the outer wall when it is not in use. The structure opens for the afternoon and evening outdoor experience without using more or less effective and poisonous balsam against mosquitoes, smoke or the like. On the day the cover can possibly remain unfolded as protection against flies. In addition, the roof of the structure can be supplemented with rainproof fabric or sun, so that it can act as protection against sun or rain.

Brief description of the Drawings To illustrate an example of cover design, the following drawings are described. Fig. 1 is a cross-sectional view of the roof perpendicular to the external wall (1) that constitutes one of the four walls of the roof. Fig. 2 is a front view of the folded cover against the external wall (1). Fig. 3 is a front view of a detail of the hydraulic control of the structure. La, Fig. 4 is a cross-sectional view taken along line II of Fig. 3. Fig. 5 is a cross-sectional view of a spring of plastic (32) in the partially stretched condition of the spring and the network (2). Fig. 6 is a front view on line II-II of Fig. 5. Fig. 7 is a stylized cross section of a structure that is modified due to lack of space. In the unfolded condition, Fig. 1, the mosquito net (2) constitutes the roof and three of the walls of the roof. that (19) is possibly fixed on the floor, so that the spring of (9) does not pull it backwards. Alternatively the spring of (9) is locked in this position. Considering this alternative, it may be practical to let the roller (9) cover the profile (19) and hold the other end of the net to the wall. Subsequently, the two vertical networks in (10) can be rolled up and fastened to the net from the roller (9) and / or the frames (3), (4) and (11), for example by means of a patented system similar to Sailboat, where the net is pressed on a plastic tape with vertical hooks that correspond to the width of the mesh of the network. The manual folding and unfolding of the structure can be machined, for example, by means of the mutually connected motors (18), Fig. 2, which the pipes can turn (5) and thereby the frame (11) at 90 degrees and locking it in an arbitrarily chosen position, for example by means of a worm. The motors can be driven manually, electrically, hydraulically or pneumatically. In an alternative design the folding and unfolding of the structure occurs by means of two hydraulic piston cylinders (13) which are connected in series with each other by means of pipes and hoses (14) connecting the lower end of a cylinder with the upper end of the other cylinder. Taking into consideration the space, the cylinders can be telescopic. A hydraulic pump (15) driven manually or by motor is connected by means of the hose (17) to one of the cylinders (13) and drives the piston thereof in one or the other direction. Through the hose (14) the movement propagates to an equally large movement of the piston in the other cylinder (13). The handle (29) can be locked in any desired position. To compensate for the initial "dead" folded position of the structure where the cylinders (13) as well as the frame (11) are vertical, figs. 3-4, one side of the frame (11) is provided with a longitudinal cover (21) with a groove (31) in which the end of the piston (23) is driven by means of a pin or roller (20), possibly via a connecting bridge (27) provided with a stop (30). A console with the upper face (22) inclined on the wall in the plane of movement of the piston is appropriately mounted. During its initial downward movement the piston or console volume (22) will cause the frame (11) gradually push away from the wall when the bolt or roller (2) reaches the end of the cover (21), this will press down on the extension (25) of the cover, and change the angle between The frame and piston will be large enough for the piston to act directly on the frame and press it down 90 degrees to the floor. Supplying the roller (9) with another similar roller in place of the profile (19) and by means of an appropriate interchange between the two rolls of a continuous sheet consisting of sections of mosquito net, fabric against the light and transparent fabric impermeable to water, respectively , the structure can also be used as protection against sun and rain, respectively. For example, the entire sheet in the folded position of the structure can be rolled up on the roller (9) and the outermost layer of the roller consists of fabric against the sun, the next layer of mosquito net and the innermost of waterproof transparent material to the rain. During the day the section against the sun can be extracted outside the roller (9). Before obscuring this section by means of a handle on the roller (19) it is wound on this roller, so that the netting is removed from the roller (9), and so on if it rains. The roller (19) is not necessarily spring-driven but can be provided with a sprocket and a hook to lock the rotation of the roller in arbitrarily chosen positions.

To avoid the manual attachment of the nets (2) vertical mosquito nets of the rollers (10) to the roof structure and also to avoid the airtightness of all the openings along the rollers (9) and (19), the nets in sides and roof can be joined to form a continuous tent fastened to the frames (3) (4) and (11), the rollers (9) and (10) are left outside. Instead of the rectangular longitudinal section, the frames can possibly be rounded. In the folded condition of the structure, the nets will be folded instead of rolled up and therefore occupy more space. To handle the folded nets, accessories can be placed on the wall (1) to be joined by the rope, fabric or net, or fins hinged or spring-loaded longitudinal on each of the three bent networks for fastening, compression and protection against the sun of the networks. The fins can be moved possibly hydraulically by means of the cylinders 13. In addition the elastic material can be fastened to or weave in each of the networks for contraction of the network. Specifically, each of the two corners between the sides and the roof can be provided with an elastic cord.

Alternatively, the bending of the networks can be controlled by means of the springs (32) connected to the network, figs. 5-6. The spring material can be plastic, for example polypropylene. As shown in fig. 6 the longitudinal direction of the individual rests (32) is appropriately oblique in relation to the direction of folding so that the total thickness of the spring in the folded condition is minimal. To support the net (z) in the folded condition of the structure and also to raise and lower the structure, continuous ropes (12) can be passed through eyes in the upper part of the frames (3) and (4) and via wheels on the wall (1) on both sides of the structure are guided to the same drum in a manual lathe or driven by a motor mounted on the wall (1). For it unfolded from the structure, spring-like or elastic elements, for example rubber bricks, can be mounted between the wall (1) and the foot of the frame (3) and mutually between the feet of the frames (3), ( 4) and (11). Protection against sun and rain can be achieved by replacing the mosquito net (2) in for example the outermost frame, in this case between the frames (4) and (11), by means of closed fabric, or supporting these, possibly via a spring-loaded roller (9) on the wall (1), in a frame with separate hinges with the same axis, but outside the other frames. If for example a terrace-wall (36) in front of the wall (1) r fig. 7, prevents the end profile (19) from moving all the way down to the floor, the frame (11) on either side can be provided with a hinge (35), so that the outer end of the frame, (37) ), can rotate down to the vertical position when the structure is deployed. An elastic or spring-like element, for example a rubber brick, in the hinge (35) causes the rotation, and a stop on the lower surface of the hinge limits the rotation.
