Dismountable I ¹ IoB

In recent years, water sports, especially swimming, have grown and diving, increasingly popular »This has led to the need for a simple aid, a boat or a raft that facilitates movement on the water, as a resting point for swimmers or bathers and if necessary Can serve as a rescue aid and is easy to use handle and transport is <>

Hitherto known devices are boats or rafts that are either large and heavy or, because of their light and simple design, do not offer sufficient security it can be carried anywhere in comfortable hand loads _o The invention is based on a collapsible raft which has at least one inflatable floating body and rigid elements

constrict them through inflated floats and thereby firmly connecting it to the rigid elements. Preferably, the raft has a plurality of elongated cylindrical Float on «Next it is provided that the floats are parallel to each other on the transverse to them rigid elements are attached o

τ *

The basic features alone result in an extremely resistant arrangement of floating bodies and rigid ones Elements «, such an arrangement can be set up in a few simple steps can be made from the individual parts. Despite the reliable connection between floating bodies and rigid elements the weight of a finished raft arrangement is low, so that the raft can be handled by children in the water without difficulty can be.

In a preferred embodiment of the invention, the rigid elements flat, parallel to each other arranged spars. These spars can look for a further feature according to the invention, two neighboring be connected by a platform ο

To carry out the invention, simple, tubular Floats are used, which are made of a waterproof and light and seawater-resistant material are, in particular made of a cotton fabric that is coated with rubber or a similar mass. Using such simple, tubular floating body is provided in a further embodiment of the invention that within of the space bounded by loops and spar at the top of each float to stiffen the of Float and spars formed arrangement at least

a rod arranged parallel to the Schwiimiikorp's axis is. Such a stiffening rod does not need to be specially attached, but is according to the invention by the inflated float held in the loops, on the other hand the rod to stabilize the float contributes.

Tr H

The stiffening rods are preferably made of wood, with a plastic cover to protect against weather and seawater influences is provided »The ends of the stiffening rods are provided with rounded caps, preferably made of a plastic material, that protect the skin of the float against unintentional damage by the rod end «

The basic shape of the raft according to the invention has two parallel floating bodies which are attached to the lateral ends of at least three transverse spars _{0 the} size of the floating body can be selected as required. To increase the load-bearing capacity and to additionally stabilize the floating position, a third floating body can be arranged in a further embodiment in the middle between the two floating bodies and parallel to them, which preferably protrudes to one end of the raft and under the two spars facing this end is attached ο

Further advantages and features of the invention emerge from the following description and the drawing in which two preferred embodiments of the invention, for example are explained and shown »They show:

Pig ο 1 a top view of a raft according to the invention, ''

Pig. 2 shows a section through a stiffening rod which forms part of the raft according to FIG. 1,

Fig. 3 is a view of a section along the line 3-3 of Figo 1, seen in the direction of the arrow, and

4 shows a simplified representation of a further embodiment of the raft according to the invention »

The raft, generally designated 10 according to FIG. 1, has two floating bodies 12 and 14. The floats 12, 14 have the shape of elongated hoses, the extremities of which are tapered and rounded o The floating bodies 12, 14 are provided with valves, not shown, through which the floats are filled with air, or «the in the floating body air can be released. In a practical embodiment, there are floating bodies Made of light and seawater resistant cotton fabric, which is double coated with high quality Rubber has been made waterproof.

The floating bodies 12, 14 are attached to the ends of the rigid elements 16, 18, 20 o The elements 16, 18, 20 are flat bars made of wood or some other lightweight, durable material such as fiber-reinforced plastic, can be made. In a preferred embodiment, obeche wood is used for the spars 16, 18, 20 which has been provided with a triple lacquer coating. If the spars 16, 18, 20 in the foregoing as "Rigid elements" have been designated as the opposite to the non-rigid elements 12, 14 »namely the floating bodies are highlighted »The elements

Spars 16, 18, 20 should of course have a certain elasticity, which is guaranteed when for the Holme a knot-free wood is used, which has about the properties of Abachi wood ο

A seat platform 22 is attached to two bars 18, 20 » The seat plate can be a hardboard, which by corresponding ^ Surface treatment and painting is weather and seawater resistant

Between the top of the float 12, 14 and the bottom of the spars 16, 18, 20 are stiffening rods 24 arranged. The stiffening rods 24 »see Figo 2, consist in the embodiment shown here made of round wooden rods 28 made of knot-free wood. The wooden rods 28 are with a plastic cover 30 provided and wear on the two Ends of each end caps 32, which are rounded »This avoids that the ends of the stiffening rods 24 with one edge rub against the skin of the float 12 or 14 ο

As already mentioned, the floating bodies are held on the bars 16, 18, 20 in that the floating bodies 12, 14 when inflated are constricted by loops attached to the spars »If necessary, the floats can 12, 14 have several chambers lying one behind the other, so that cohesion is maintained even if one chamber is injured the raft is guaranteed »

The remaining parts of the raft are secured by screw connections 26 connected to each other »For example, the seat plate 22 is attached to the

Spars 18, 20 screwed on. In addition, see Fig. 3; '■ the the loops tying around the float were fastened to the spars by screwing

According to Pig »3, the floating body 14 is made up of a strap section 40 existing loop arranged. The ends of the webbing section 40 are sewn at 44 and Glue firmly and securely connected to one another, so that a closed band is created that is folded flat ο The flat folded closed belt strap is arranged in a U-shape under the spar 20 in that the closed Ends 42 of the folded closed band 40 receive pegs 46 through which the screws 36 are inserted,

which also go through the tape and through the spar 20 and with a wing nut 34 on the spar top are specified ο To secure, washers 38 are also arranged between all parts, of which only here the washer between the spar 20 and the wing nut 34 is shown «

Between the strap attachment, the underside of the spar and the top of the floating body are the stiffening rods 24 », which are through the inflated floating body in their position are secured and vice versa to stiffen the float and that formed by the spars 16, 18, 20 Contribute to the raft »

Fig. 4 shows an embodiment of the invention Raft designed to increase the load capacity and improve maneuverability with a third float is provided »The raft 100 consists of the two side

Floating body 112, 114, as well as the third floating body '' 116, which is arranged in the middle between the two side floating bodies so that it protrudes beyond the two side _{floating bodies at one end 0} In the embodiment shown here, the floating bodies 112, I14 and 116 same size However, it is also possible to use larger ^ or »longer.

The raft 100 is provided with three transverse spars 122, 124 and 128 If longer side floats are used, it is advisable to use a correspondingly larger number of To provide spars ο

The seat plate 126 is releasably attached to the spars 124 ″ and 128 ο Under the seat plate 126 or the spar 124 carrying the plate and the spar 122 in front of it is a board 118 attached, which carries crossbars 120, on which the Loops for constricting the floating body 116 are attached in the same way as shown in Fig. 3 o The board 118 tapers towards the front end. »It not only serves as a support for the crossbars 120 on which the loops are attached are attached, but also serves to stiffen the floating body 116. Because of this, are on the floating body 116 no bars 24 arranged
