Description

The utility model relates to umbrellas and can be used as a stationary or portable umbrella.

Known umbrella containing knitting needles, located on top of the awning for protection from rain and sun (see Description of the invention to patent No. 2110199 of the Russian Federation, IPC A 45B 19/00. Publ. 10.05.98).

The disadvantage of this umbrella is that the knitting needles are stiff and, when the tent is pulled over the knitting needles, creates a hard contact with the knitting needles, leading to premature destruction of the tent at the contact points of the tent along the length of the knitting needles, which reduces the quality of the umbrella and shortens its service life.

The technical result of the improvement is achieved by the fact that an umbrella containing knitting needles located on top of the awnings for protection from rain and sun, ACCORDING TO THE USEFUL MODEL, DIFFERENT THOSE, that the knitting needles, working in tension or having contact along the length of the knitting needles with the awning, are made of wire ropes or belts.

TECHNICAL RESULTS: the tent is contacted along the length of the needles, the kinematic chains are facilitated, which improves the quality and service life of the umbrella tent.

The execution of knitting needles from soft polymer or natural tape ropes or belts makes it possible to ensure soft contact of the awning with the needles, which is important when pulling the awning over the needles and when operating the awning in windy weather. The soft knitting needles in V1ld, tape ropes or belts, when the tent is tensioned, take the form of an awning and dampen the impact of the tent on the knitting needles due to the elastic properties of the ropes or belts. The awning is pressed by the planes of the ribbons of the knitting needles, and moves under the influence of the wind together with the knitting needles. Awning will not be damaged) | it is given by soft knitting needles that prolongs service life

tent in a condition suitable for protection against rain and the sun.

Tensile spokes made of ropes or belts have elasticity, are more flexible and less wedged and work easier in the kinematic chain, which improves the opening and filling of the umbrella.

The umbrella is shown in figures 1 and 2.

The umbrella contains at least four soft flexible knitting needles 1 of ropes or belts, for example, 1 prone, dacron threads made of polymer or natural threads or leather. The spokes are mounted in an umbrella so that they work in tension.

Awning 2 made of waterproof fabric is located on top of the knitting needles. Knitting needles 1 (see figures 1, 2) in the umbrella are fixed at one end in the upper fixed socket 3, and at the opposite ends they are fastened to the lower part of the hollow struts 4 located under the needles 1 or to the plugs 5 of the ends of the struts 4. The upper ends of the struts 4 are hinged to movable intermediate outlet 6.

To automatically open the umbrella and pull the spokes from the ropes or belts between sockets 3 and 6, a spring 7 is installed, which is constantly pressed between the sockets 3 and 6 in the umbrella. With the umbrella open, the spring 7 is partially uncleaned, and with the umbrella closed, the spring 7 is partially compressed. The spring is made in the form of a cylindrical spiral and spans the strut 8 concentrically with a gap.

Mobile intermediate socket 1a 6 freely covers the rack 8.

For synchronous operation of the spacers and umbrella spokes, each or part of the spacers 4 is pivotally connected to the ends of the struts 9, which are pivotally connected by the opposite ends to an additional movable bottom outlet 10, which concentrically with a gap covers the rack 8 under the limiter 11.

The limiter 11 is located on the rack 8 between the outlets 6 and 10 and is designed to keep the spacers 4 running to the rack 8 and ensure a confident zone of self-development of the umbrella.

The length of the struts 9 is chosen so that with respect to the strut 8, the longitudinal axis of symmetry of them lie in the same plane perpendicular to the strut 8 or the longitudinal axis of symmetry of the struts 4 and the longitudinal axis of symmetry of the struts 9 would conditionally be the lateral sides of an isosceles triangle or right triangle, where the greater leg which coincided with the longitudinal axis of the strut 9.

To close the umbrella, a flexible rod 12 is suspended from the socket 10 in the form of a cord with a ring 13 or a handle that can catch on a stopper 14 designed to fix the umbrella in the locked position, which protrudes from the rack 8 in the form of a pin with a head at the end.

Around the perimeter, the awning 2 is attached to the caps 5 by the belts 15 of the awning 2. The assembled state of the belts 15 is held by inserts 16 in the loops 17, which are sewn to the tent 2. On top of the tent 2 is pressed to the socket 3 by a flash 18. Each plug has a hole19, which has one side of the stub 5 is narrower than on the other side. The belt loop 17 is threaded from the narrow side, pulled through the hole 19, and the insert 16 is inserted into the loop 17 in the form of a plastic or wooden cylinder. Then the loop 17 with the inserted insert 16 is again tightened into the hole 19 until the loop 17 is pinched in the hole 19 and the connection point of the loop 17 and the plug 5 is formed. Similarly, the loops 17 of the ribbons or belts of the spokes 1 are fastened in the socket 3, i.e., in the socket 3 there are holes 19 in number equal to the number of knitting needles 1 into which the end loops of the spokes are inserted, which are fixed in the holes 19 with the help of inserts 16, which clamp the end loops 17 of the needles 1 in the conical holes.

with an awning, can be made of charcoal twisted steel ropes with a protective sheath in the form of a steel spiral that covers the outside of the rope and has a polymer coating on the outside.

The device operates as follows.

Awning 2 is put on the frame of the umbrella with knitting needles 1 from soft tape ropes or belts and taped on the upper socket 3 with a flash (see Fig. 3), and at the ends of the spacers 4 they are jammed in the caps 5 (see Fig. 4). In a candy example, an umbrella is shown which breaks itself when the flexible rod 12 is removed from the stop 14. In this case, the spring unclenches and fastens the socket 6 to the waitress 11, which leads to the pulling of the socket 10 and the strut 9 to the waitress 11 from the bottom and to self-rafting of the umbrella. When rafting the umbrella, the awning falls tightly over the ribbon knitting needles, which take on the shape of an awning at the junction of the fune with a smooth transition to the method with fans or wedges of awning 2. In the wind, awning 2 swings together with soft knitting needles 1 pressed against the awning 2 while each spoke 1 and awning 2 of each other Do not hurt. With soft knitting needles 1, awning 2 is more wear-resistant and increases its service life without local destruction of awning 2 from knitting needles 1, which improves the quality of the umbrella. To cover the umbrella, it is enough to pull the flexible rod 12 and the umbrella will begin to be closed. The spring 7 will be compressed from the pressure on it of the socket 6 and will remain compressed in the folded umbrella, saving energy for the subsequent rafting of the umbrella.

In addition, soft knitting needles 1 do not injure the awning 2 during transportation and storage of the umbrella, additionally protect the awning 2 from contact with the rigid elements of the umbrella (with struts 4, with struts 9).

Spokes made of steel ropes in a spiral shell with a polymer coating on the outside can be used to obtain sharp transitions between the wedges or fans of the awning 2. In this case, the steel rope has the ability to move inside the spiral sheath, which is stationary relative to the contact with the sheathing awning 2 and does not cut through the latter.

similar applications known knitting needles. For the manufacture of knitting needles 1 from soft tape ropes or belts, it is possible to use the same equipment as for the cut and loshiva tent 2.

TECHNICAL RESULT: soft contact of the awning 2 along the length of the spokes 1 is ensured, which improves the quality and service life of the awning 2 of the umbrella.
