Description

BACKGROUND OF THE INVENTION The present invention relates to a multi-position tubular camping bed with a foldable seat or lying frame, a textile or plastic insert mounted on the frame, and two-legged legs and armrests.

Different types of deck chairs have been known for a long time, and recently also camp beds, which can be adjusted in several stages according to your preference.

Such deckchairs and camping beds usually consist of an aluminum tubular support surface made of fabric stretched on a frame and foldable legs connected to the frame. Such a construction is also described, for example, in U.S. Patent No. 3,987,504. After the legs have been folded in, the camp bed can be folded into two or three layers so that it can be treated as a single sheet.

There are also special solutions where the camp bed can be packed in a small bag or even unpacked in a backpack frame. The former is exemplified in U.S. Patent No. 3,965,502 and the latter in U.S. Patent 4,056,857.

These designs are very practical, easy to assemble and disassemble, and therefore easy to store and transport. However, they provide only a single lying position, which is generally not satisfactory when used in holiday homes and resorts.

The classic wooden deck chairs and their modern metal variants can also be folded and unfolded and can be secured in multiple positions at the same time. This is not only beneficial for multi-purpose use, but also a health benefit. It is a well-known fact that even sitting optimally adapted to a person's anatomy is tiring after a period of time when there is no way to change posture. Sitting in the same position permanently forces the most tired part of the spine, the lower section, to occupy the same position, and this is a constraint not only for the joints but also for the spinal muscles.

That's why variable seatings are used not only in the furniture industry, but also in vehicles, for example. (See U.S. Patent Nos. 3,973,799, 3,940,182, and 4,043,593).

Adjustable seating is used in homes and workplaces. U.S. Patents 4,071,275 and 4,672,342 disclose adjustable armchairs. The seating arrangements described in U.S. Pat. No. 3,902,754 or U.S. Pat. No. 4,005,903 are also adjustable.

However, the common disadvantage of all these solutions is the complex construction of a large number of moving parts, clamps and other structures.

In resorts, hotels, beaches, etc. however, it is obvious that the optimum solution is to avoid stumbling over the various adjusting mechanisms and to ensure the least possible posture of the various postures.

This is an advantage of the well-known camping and deck chair solutions, in which the position change can be achieved by shifting the center of gravity of the body. Such known deck chairs comprise articulated frame and foot members which change their relative position with respect to the center of gravity change and thus allow for different postures.

This solution can be called user-friendly, but its construction is relatively complicated, and its production is difficult and expensive.

The purpose of the present invention is therefore to provide a multi-position tubular camping bed that allows you to simply change your posture by shifting the center of gravity of your body, but without the use of moving parts, making production simple and cheap.

1® In accordance with the present invention, the object of the present invention has been accomplished by providing the legs and arms on one side of a single endless section of a camping bed with a curved frame suitable for seating or lying, a textile or plastic insert mounted on the frame and a double leg and armrest. they are formed in such a way that the lower part of the mold comprises at least two straight sections which are obtuse and interconnected by curved portions.

The endless piece is preferably rectangular, the sides of which are optionally joined by curved portions. Preferably, the sides of the infinite profile forming the armrest are at right angles to each other.

Further details of the invention will be illustrated by way of an exemplary embodiment. In the drawing it is

Figure 1 illustrates a multi-position camp bed of the present invention in a visible seat position

Figure 2 shows the camping bed shown in Figure 1 in a lying position.

In the figures it is seen that the frame 1 of the camp bed is secured with armrests 2 and 3,4 feet, which are made up of a single piece in pairs.

The legs 3 and 4 are connected at the bottom by 5 tie rods. The connecting rod 5 comprises branches 5a and 5b. In this way, the armrest 2 and the legs 3 and 4 connected to the connecting rod 5 form a single endless profile.

The sections above this frame form essentially the armrest 2, while the sections below the frame 1 form the legs 3 and 4 and the connecting rod 5.

The frame 1 of the camp bed is normally provided with a textile or plastic insert 50, which is not shown in the drawing for simplicity. Likewise, the optional reinforcing elements which connect the two sides of the frame 1 near its ends and at the bent central portion are not shown in the drawing.

These reinforcing elements may be cross bars and / or transverse textile or plastic bands or straps.

Figure 1 shows that the deck rests on the branch 5a of the connecting rod 5 of the endless section. Accordingly, θΟ can be used as a recliner, as the center of gravity of the occupant is above this branch 5a. If the deckchair is provided with said reinforcing straps, it is preferable that one of them is positioned at this center of gravity.

In Figure 2, the branch 5b of the bridging bridge 5 of the infinite member rests on the ground, i.e. the structure acts as a rest. It is also clear from the figure that the center of gravity of the lying person is still above the horizontal branch 5b.

The deck chair of the present invention can thus be used in both the sitting position and the lying position as shown. The change of position can be accomplished simply by tilting the bed on the curved portion connecting the branches 5a and 5b. This can be done by sitting or lying down on the bed, changing posture, shifting the center of gravity, or before sitting or lying down on the bed by hand.

It is clear from the example shown that the present invention is based on an endless body attached to a frame, comprising at least two straight sections which are obtuse and interconnected by curved portions. In the embodiment shown, these are the branches 5a and 5b and the infinite shape is a general rectangle.

However, the deck chair according to the invention can be formed in many other ways than those shown. The infinite shape may be other polygonal or even partially curved. For example, the armrest 2 and the legs 3.4 may be formed as a single circular arc.

In addition, the proportions of the infinite shape can be varied, of course, always keeping in mind that the lower obtuse segments ensure the desired positioning.

The deck structure is extremely simple in any design, with no moving parts, and is extremely easy to manufacture and use.
