Abstract

Universal raft for skiing from water and snow slides is used in the entertainment industry. Raft is a supporting inflatable chamber made of reinforced PVC plastic, in the form of a figure eight, having a deflection relative to the horizontal plane, equipped with a valve for pumping and convenient handles.

The materials used make it possible to ensure year-round use both in enclosed spaces (water parks, pools) and in the open air (snow-ice slopes). This design allows you to significantly increase the wear resistance and durability of the product, as well as significantly increase the level of safety and comfort when riding.

Description

Characteristics of the elements.

1. Material used: multilayer PVC plastic reinforced with a net of propylene yarns.

2. Tubeless bearing shell.

3. The shape of the raft with a transverse bend.

Generic concept.

Raft for water and snow slides.

The field of technology.

The utility model relates to the field of devices (inventory) for extreme entertainment. Namely: downhill runs along the gutters of water slides (in water parks) along equipped and unequipped snow slopes.

The level of technology.

Analogs of a utility model can be divided into two categories:

1. For winter operating conditions.

2. For operation on water slides.

The closest analogue of raft for winter operation is pat. 2013156599/11 "Inflatable sled." In fact, this is an inflatable car camera, placed inside covers sewn from polymer materials in various combinations. The shape of the outer cover determines the appearance and shape of the sleigh. These inflatable sledges in various designs may or may not have elements attached to the outer cover, in the form of handles or loops for towing. Most often, an inflatable sled has the shape of a flat torus, or an irregularly shaped torus, which is associated with the thickness variation of the rubber chamber, and as a result, the uneven inflation of the shell. The design of the outer cover provides for the overlapping of the inner hole (seat) to prevent contact rolling with the surface of the slide during movement.

The closest analogue of raft for operation on water slides is made by the American company Zebec, founded in 1994 and registered in Ohio, (www.zebec.com)

Among the various raft models produced by Zebec, there are models representing an inflatable tubeless design made of PVC plastic in the shape of a torus or figure eight. This form of a flat torus does not guarantee movement without rotation around a vertical axis and often leads the skater to move his back forward in the gutter of a water slide. In the manufacture of these rafts, single-layer PVC plastic without reinforcing mesh is used.

The disadvantages of these analogues include: Inflatable sled pat. 2013156599/11

1. Application as a bearing shell of an automobile camera. A specific spool valve makes it impossible to inflate the sled without the use of additional devices, directly at the skiing site, which leads to the need to transport the sled to the skiing place in an inflated form. With a sufficiently large size of the sleigh, transportation by personal transport becomes difficult, and by public transport - impossible.

2. The use of a car camera in the sleigh design makes it difficult to store the inflatable sleigh at home, due to the sharp smell of rubber. The plasticizers and soot used in the rubber diffuse over time (1-2 months) into the material of the outer cover, which leads to a change in the color of the outer cover and the loss of the aesthetic component, which is not unimportant for an inflatable sled, as for entertainment.

3. The shape of the torus used in an inflatable sled does not provide for controlled descent without rotation around a vertical axis. The back-to-back movement leads to discomfort and dramatically reduces the safety of the descent as the skater does not see the relief of the slope, people on the slope, etc., of possible obstacles.

4. The area of the supporting surface of a torus-shaped inflatable sled with a closed middle cavity is large enough, which leads to increased resistance when sliding, reduces speed and reduces the range of free roll-out, which makes skating less interesting and exciting.

5. The design of the inflatable sled and the materials used for their manufacture interfere with the use of this product for water slides or other water activities.

Rafts for Zebec Water Slides

1. The use of a single-layer PVC plastic material without reinforcing mesh as a material for the raft load-bearing shell negatively affects the durability of the raft and reduces the safety of skating. The absence of a reinforcing mesh in the shell material leads to an instant pressure loss in case of its possible damage.

2. Application for connecting the elements of the bearing chamber of welds of the type "butt". Sutures of this type work to break. In addition, the seam at the time of welding is subjected to heat, which leads to evaporation from the seam of the plasticizer DFT, used to soften PVC plastic. The combination of these factors makes the seam more rigid and less durable.

3. To ensure the sliding of the raft in the form of a flat torus along a slide with a semicircular groove, the raft should take the form of a groove. With a high value of the internal pressure inside the raft shell and additional load due to the weight of the rolling, closing seams experience increased loads and bending stresses, which leads to cracks, depressurization of the seam and failure of the product. Cracks in the material at the weld point make such damage completely unrepairable.

4. The shape of the torus does not prevent the rotation of the raft around the vertical axis when moving along the gutter of a water slide. This negatively affects safety and comfort when riding, which is especially important for people with a weak vestibular apparatus.

The utility model is aimed at solving the following problems:

1. Improving the safety and comfort of riding.

2. Improving the durability of the raft, in comparison with existing analogues.

3. Providing adjustment of the sliding speed of the raft on a water slide.

4. Creation of a universal, all-weather raft for skiing on water and snow slides.

5. Providing the ability to pump raft without additional devices.

6. Elimination of pungent odors that make it impossible to store rafts at home.

To achieve the above objectives, the following is proposed:

1. To increase the durability of the raft, apply, as the material of the supporting shell, multilayer PVC plastic with a reinforcing mesh of PET fiber. The most loaded zones of the supporting shell are additionally strengthened by gluing from the inside or outside the PVC linings or polyurethane film.

Use glue or weld seam of the "overlap" type to connect the elements of the raft.

2. The following measures are applied to increase safety and comfort:

a) Installation of durable, comfortable handles in ergonomically designed places, in an amount of from 2 to 8 pieces, depending on the configuration of the raft. This allows not only to ensure safety during skiing, but also to reliably hold the raft during landing in the starting area of the hill. It also provides the convenience of transporting rafts on stairs or slopes to the starting point.

b) As a measure to ensure directional sliding and prevent rotation around the vertical axis, it is proposed to use a raft shape that repeats the curvature (radius) of the gutter of a water slide. To do this, it is necessary to give the raft an oblong shape in the plan and transverse bending, which will allow you to transfer anchor points from the sides to the middle of the gutter. To obtain the necessary shape, the raft elements are cut taking into account the stretching factors of the warp and weft of the reinforcing mesh, as well as the diagonal elongation of the material. The influence of the degree of elongation of the threads in different directions, allows you to get the desired shaping, only using the internal pressure of the carrier chamber, without the need for other external influences on the raft.

c) The use of an additional structural element in the form of a wide tape or circle fixed in the central hole (s) of the raft by gluing and lacing. To prevent the displacement of the rolling towards the sliding surface and to eliminate the possible contact of the rolling with the surface of the slide during movement.

d) A reinforcing mesh made of polyester prevents the spread of tears and cracks, which prevents explosive loss of pressure inside the bearing shell in case of possible damage during skating.

3. The issue of adjusting the speed of descent along a water slide is solved by using reinforced PVC as a raft shell. With increasing pressure inside the bearing shell of the raft, its rigidity increases, which leads to increased friction of the raft on the sides of the trench and slowing down the slip, up to a complete stop. By adjusting the internal pressure, it is possible to select the necessary degree of friction of the raft on the walls of the gutter and thereby regulate the descent in a wide range of speeds, regardless of the amount of water supplied to the gutter. The ability to adjust the speed of the descent also has a positive effect on improving safety and riding comfort.

4. The use of environmentally friendly and durable reinforced PVC plastic, allows the use of a single-design raft, both on water and on snow-ice slides. In this case, in both cases, it is possible to use raft with or without reinforcing elements.

5. The use of a valve with a large flow area and a special rod allows you to pump the raft, without additional devices, using only the power of the lungs. This makes it possible to pump up the raft, being directly at the skiing site, which eliminates the need to transport the pre-pumped raft and avoid the inconvenience associated with it.

6. The use of eco-friendly PVC plastic and tubeless design, allows you to store the raft at home or in poorly ventilated rooms, without the discomfort associated with the sharp smell of rubber, which is always present when using car cameras as a load-bearing element in similar products.
