Description

The present utility model relates to sports equipment and concerns, in particular, the design of so-called flying discs - Frisbee discs.

A flying disc is the general name of a sports projectile, which is a plastic disc with curved edges with a diameter of 20-25 cm. The disc is made in such a way that lift is created during its flight, which makes it possible to throw discs over considerable distances and with great accuracy. Most Russian-speaking people will call such a disk a "flying saucer". The next most popular option would be the Frisbee. People who are involved in various sports that use a flying disc simply call it a "disc" or "plate". "Frisbee" is technically not a common name for flying discs, but a trademark of Mattel's Wham-O Corporation toy division. Similar to the situation with the name of any copiers copiers, the word "frisbee" is used to refer to flying discs in general.

To cope with the 4 physical forces (traction, gravity, lifting and air resistance), the disk must be kept by rotating around its own center. To fly, it needs to have convex and concave surfaces. Above the convex, the flowing air flow will accelerate, under the concave it will slow down. Higher speed will create lower pressure and lift will be born. As a rule, the convex surface is thin in thickness, and the bent edge is thick. Since the main mass is concentrated at the edges, the flight and rotation will be more stable than with a flat product. A plate "with sides" resists air more, but the effects are distributed evenly. For example, thanks to the trailing edge, the rear lift is increased and the disc does not tip over.

Thus, a Frisbee disc is known, containing a plastic case, which is a thin-sheet structure round in plan, the front part of which is made convex and is a fragment of a spherical surface, along the edges of which an edge is made, bent in the direction opposite to the convexity, and on the inner surface of the structure along its in the center there is a socket with a side wall, closed by a lid and inside of which there is one LED, a power source and an on / off button for the housing lighting unit, which includes a set of optical fibers, while on the inner surface of the structure there are formed radially extending from the side wall of the socket through the openings in it and ribs reaching the edge of the body with a groove longitudinal along the length of each rib, inside which an optical fiber is fixed in each rib, facing from one end to the luminous part of the LED fixed in the center of the disk in the socket (US 2005090177, A63H 33/18, A63H 33/22, published 04/28/2005 ).

This decision is accepted as a prototype for the declared object.

The disadvantage of this solution lies in the lack of operational and long-term reliability of the disk, which consists in insufficient structural strength, leading to structural failure. This is due to the fact that the Frisbee disc is used as a game projectile, which is thrown according to the rules of the game or in crayfish entertainment. During such games, the disc is subjected to shock loads (in the event of a fall or hit against a wall, if the game is played in an enclosed area). In this regard, the body of modern Frisbee discs is made of polypropylene, which has high elastic and deformation resistance to dynamic loads. But the implementation of the case from modern material does not provide high reliability in terms of structural strength as a whole. For example, in a known solution, optical fibers are tightly packed into open grooves in the ribs and are held in them due to material friction. Upon impact, an oscillatory process occurs that squeezes these fibers out of the grooves due to the fact that the material of the body and, accordingly, the ribs differ in structure and elastic properties from the material of the optical fiber sheath.

The poor operational reliability of the disk is also determined by the fact that the ribs are not made integral with the body, but are fixed in the traditional way on the body. The socket itself for electronic components is also made in the form of a separate part and is fixed in the center of the disk. Thus, at the attachment points, a material structure is formed, which differs from the material structure of the parts to be joined. The strength of any disk is determined by the fact that it is able to take the peak external load in a separate local place. At the moment of loading, an oscillatory process occurs in the structure of the material, propagating in the direction from the point of application of the peak local load. Due to intermolecular bonds, this process propagates along the structure and dampens the frequency and amplitude of vibrations as they move away from the point of application of the load. Due to this, internal damping of the impact energy occurs within the elastic bonds of the material molecules.

If an excellent structure with a different arrangement of molecules and bonds between them appears on the path of propagation of an oscillatory wave, then the wave hits this structure without damping the energy. Places of gluing or welding of the socket and ribs are such structures. That is, the impact energy is transferred to other parts. This leads to the destruction of the structure.

In addition, in the known solution, optical fibers are used to propagate light from the LED over the entire surface of the housing. This static illumination of the disk is used for visible control of the flying disk and the place of its fall and does not carry any other functional load. Upon impact, the fibers fall out of the fins, which leads to the termination of the illumination mode.

This utility model is aimed at achieving a technical result, which consists in increasing the structural strength of the disk to increase the operational durability of both the case and the electronic part responsible for the illumination of the case.

The specified technical result is achieved by the fact that in a Frisbee disc containing a body made of a polymer material, which is a thin-sheet structure round in plan, the front surface of which is made convex and is a fragment of a spherical surface, and along the edges of which an edge is made that is bent in the direction opposite to the convexity front part, on the inner surface of the structure in its center there is a nest with a side wall with holes, closed by a lid and inside which there is a power source and an on / off button for the housing lighting unit, while on the back surface of the structure there are formed nests radially extending from the side wall and reaching to the edge of the body of the fin to accommodate the optical elements of the body lighting unit, the ribs are made hollow with the location of their cavities opposite the holes in the side wall of the socket, each optical element of the body lighting unit is made in the form of an LED strip passed through a corresponding hole in the side wall of the socket for placement in the cavity of the fin and connected to the board with electronic components for controlling the illumination of the LEDs placed in the socket, and the body, ribs and socket with the side wall are made in the form of one piece by 3D printing.

At the same time, the electronic components for controlling the glow of LEDs include a microprocessor, an axial motion sensor and a Bluetooth unit.

On the front side of the case in the center there is a USB socket, and the on / off button for the case lighting unit is displayed on the back side of the case.

These features are essential and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

This utility model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result.

According to the present utility model, a new design of a Frisbee disc used as a sports equipment capable of flying long distances without turning over is considered. A feature of the claimed disk is its increased structural strength, which determines its operational durability without losing the function of demonstrating luminous patterns on the surface of the body.

In the general case, the Frisbee disc contains a body made of a polymeric material, which is a thin-sheet structure round in plan, the front surface of which is made convex and is a fragment of a spherical surface, and along the edges of which an edge is made, bent in the direction opposite to the convexity of the front part.

On the inner surface of the structure, in its center, there is a socket with a side wall with holes, closed by a lid and inside which there is a power source, an on/off button for the housing lighting unit and electronic components for controlling the glow of LEDs, which include a processor, an axial motion sensor and a Bluetooth unit. .

Ribs extending radially from the side wall of the socket and reaching the edge of the housing are formed on the back surface of the structure for placement in each LED strip, passed through the corresponding hole in the side wall of the socket for placement in the cavity of the rib and connected to the board with electronic components for controlling the glow of LEDs placed in the socket. . To do this, the ribs are made hollow with the location of their cavities opposite the holes in the side wall of the nest.

The peculiarity is that the body, ribs and socket with side wall are made in one piece by 3D printing. As an option, the case can be made of a unique polymer of a new generation - polypropylene, which is very resistant to various mechanical influences, is not afraid of water and high temperatures. At the same time, this material has an elastically deformed structure and the ability to restore its shape.

Below is an example of a specific implementation of the disc Frisbee (Fig. 1-7).

The basic element of the Frisbee disc, which determines its performance, is a polymer body 1 (Fig. 1-3).

The body 1 made of polymeric material is a thin-sheet structure round in plan, the front surface 2 (front side) of which is convex and is a fragment of a spherical surface. Along the edges of the structure, an edge 3 is made, bent in the direction opposite to the convexity of the front part.

On the inner surface of the structure (on the back side) in its center there is a nest with a side wall 4 with holes in it. The nest is closed with a separate cover 5.

On the rear surface of the structure there are formed slots 4 radially extending from the side wall and ribs 6 reaching the edge 3 of the housing to accommodate the optical elements of the housing illumination assembly. These ribs 6 are made hollow with the location of their cavities opposite the holes in the side wall 4 of the socket. The body, ribs and side wall socket are made in one piece by 3D printing. When using this method of manufacturing a body, a homogeneous structure is formed in the material of all its constituent elements without stress concentrators, both in the body of the body and at the points of transition from one surface to another. That is, the working conditions of the body are created exclusively in the elastic deformation mode.

When hitting an obstacle (for example, a tree or a wall), a collapse is formed on the body at the place of impact contact, leading to the formation of an oscillatory wave inside the structure of the body material. With a homogeneous structure of the material, the wave passes in the direction of impact and exerts pressure on the molecules, which increase their own frequency and vibration amplitude in the range of elastic bonds with other molecules. This increase leads to the loss of impact energy and the dissipation of this energy, which is expressed in the loss of frequency and amplitude of the oscillatory process from the impact. Having reached the opposite edge, the wave returns with less energy and completely loses it at the point of impact. This process takes place in the range of the elastic characteristics of the body material. Such deformations for a homogeneous structure of a polymeric material are natural and are expressed in thousand cycles until the material ages and loses its elastic properties. This is more than enough for the lifetime of the disk case.

Upon impact, the body experiences shape deformation, which is reflected in the shape of the ribs in the area of the impact direction line. But this form is being restored. This feature of the body with a homogeneous material structure allows the use of more complex electronic systems for illuminating the disc body, since the shock load is not transferred to them. Upon impact, the oscillation wave moves along the impact line and is reflected from the side wall of the socket, returning in the opposite direction. In this regard, it became possible to place in the socket not only the power source 7 (accumulator or battery) and the button 8 on / off the housing lighting unit, but also the electronic components for controlling the glow of optical elements.

Each optical element of the housing lighting unit is made in the form of an LED strip 9, passed through the corresponding hole in the side wall 4 of the socket for placement in the cavity of the rib 6 and connected to the board 10 placed in the socket with electronic components for controlling the glow of the LEDs (Fig. 4).

Feature of the application of LED years is that all deformation. Those coming to this element are perceived by the tape itself, that is, the base on which the LEDs are fixed. The LEDs themselves, which are sensitive to mechanical loads, are not subjected to these loads, but undergo a shift in their position in the rib. That is, when the body hits an obstacle, the shape of the body is deformed and. ribs or ribs, respectively. But at the same time, the tape itself is deformed inside the rib, as a carrier of LEDs, without transferring the deformation load to the optical elements. This important property and the fact that the deformation load from impact does not go beyond the side wall of the socket made it possible to mount board 10 with electronic components for controlling the glow of LEDs in the socket.

During installation, the operator passes the LED strip through the hole in the side wall of the socket until it stops at the end and attaches its conductive leads to the board. Tapes are freely located in the cavity of the ribs.

The electronic components for controlling the glow (FIGS. 6 and 7) of the LEDs may include a microprocessor 11, 2-6 or 9-axis motion sensor 12 and a Bluetooth unit 13 (for remote control). With such a composition, it becomes possible not only to highlight the disk for the visibility of its movement trajectory, but also to form dynamic or static pictures on the surface of the case (via Flash memory 14, which stores pictures displayed when the disk rotates). The process of forming the LED glow algorithm to obtain a full-fledged picture is not considered within the framework of this application (it depends on the software and the algorithm of the processor operation). For the sake of small dimensions, the components are mounted on both sides of the board (Fig. 5). So in FIG. 5 shows that the power supply is placed at the bottom of the socket. On one side of the board (Fig. 6), a microprocessor, a motion sensor and a Bluetooth unit are fixed. And on the reverse side of the board (Fig. 7) there is a button, a USB connector 15 and a Flash memory, which stores pictures displayed when the disk rotates. In this case, the board is located in the socket at a point where there is no path for the process of vibration of molecules caused by impact. This became possible due to the implementation of the side wall of the socket at the same time with the body.

To ensure the connection of the disk to the computer on the front side of the case in the center there is a socket 16 of the USB connector (Fig. 1). And for ease of use, the on / off button of the body lighting unit is displayed on the back of the case.

This utility model is industrially applicable and implemented as part of a small-scale production. Experiments on shock loads show the stability and continuity of the electronic part of the disk, the preservation of the image on the surface without distortion and breaks. No cracks or chips were found on the case. On the surface of the hollow ribs, there were no violations of the material structure, which could be provoked by a change in shape when the body hits an obstacle. The impact force was taken as the throw force of the user directing the disk at an obstacle at a distance of 5 m, which significantly exceeds the impact loads that occur when the disk falls during the game.

The utility model makes it possible to increase the structural strength of the disk in order to increase the service life of both the case and the electronic part responsible for the illumination of the case.
