Description

The utility model relates to the field of umbrellas and can be used as a large umbrella, for example, a garden, beach, for a cafe, used for personal or group protection from rain or sun.

A well-known umbrella (see Ukrainian patent No. 3244 for an industrial design) containing a rope, rollers for moving a rope along them, upper and lower sockets.

In the well-known umbrella, the rollers are part of individual blocks connected by a rope, which form a system for raising or lowering in the form of a chain block, which is located in the upper part of the rack and is used to raise and open the dome of the umbrella. The polyspast consists of two blocks, where one is stationary and the second is mobile. The fixed unit is hooked to the upper fixed socket, and the mobile block is hooked to the lower movable socket and moves along the rack with the socket. One of the ends of the rope (cord) is fixed to the fixed block of the chain block, and the second end of the rope is free and serves to pull one block of the chain block to the other. In this case, the rope moves along the rollers of the pulley blocks. When the pulley blocks come closer along the rack, the umbrella breaks, and when one block moves away from the other along the rack, the umbrella closes.

Pulley blocks in addition to rollers, roller axles have many more structural elements. In addition, to place the chain blocks, enough space is needed in the upper part of the rack, which increases the volume of outlets, since the ends of the spokes have to be structurally moved away from the rack so that the spokes do not press the chain blocks on the rack when the rope is etched quickly when closing the umbrella when the spokes approach front desk.

The umbrella contains a rope 1, a built-in roller 2 in the upper fixed socket 3, a built-in roller 4 in the lower movable socket 5, a sleeve 6 for attaching the end 7 of the rope 1 and for restricting the movement of the spokes 8 and struts 9 of the spokes 8 to the stand 10, the stopper 11 in the form studs for fixing the position of the lower movable outlet 5 on the stand 10.

Knitting needles 8 and struts 9 are pivotally fixed at one end, respectively, to sockets 3, 5 or vice versa.

The rope 1 is fixed by the end 7 to the sleeve 6, lowered to the socket 5 and bends around part of the roller 4 in the socket 5, then from the roller 4, the rope 1 is raised through the hole in the sleeve 6 to the socket 3, where it partially bends around the roller 2 and then hangs with the free end of the rope 1 below the position on the rack 10 of the lower movable outlet 5 in the closed state of the umbrella.

The sleeve 6 covers the rack 10 and is mounted on the rack 10 mei anode rosettes 3 and 5. The sleeve b may have at least one hole or groove for passage through it of the rope 1.

The rollers 2, 4 are mounted on the axes on which they can rotate. The axles of the rollers are installed in the grooves or plugs of sockets 3, 5. The grooves or plugs are formed integrally with the sockets during their manufacture.

Sockets can be made of polymeric material or of extruded aluminum alloy profile.

The rope 1 may be steel or a polymer material.

Sockets 3, 5 of the umbrella, together with the rope 1 and the rollers 2, 4 integrated in the rosettes, for the movement of the rope 1 along them, perform, in addition to the articulation of the knitting needles 8 or the struts 9 of the needles 8, additionally, the functions of the chain block.

In the upper and lower sockets 3, 5, at least one roller 2, 4 can be integrated for movement of the rope 1 along it.

Socket 3 may have several rollers 2, and socket 5 may have several rollers 4 for movement of rope 1. The rollers 2 are placed in the socket 3 between the spokes 8. The rollers 4 are placed in the socket 5 between the struts 9. When the number of rollers 2, 4 increases in each of the outlets 3, 5, the number of branches of the rope 1 and its length participating in raising the movable outlet 5 increases, but it is possible to reduce the pulling force on the rope when opening the umbrella.

For example, with one roller 2 in the socket 3 and one roller in the socket 5, the pulling force to the free end of the rope 1 is approximately half the weight of the structure, which rests on the lower movable socket 5. With two rollers 2 in the socket 3 and two rollers 4 in the socket 5 traction to the free end of the rope 1 is equal to about a quarter of the weight of the structure, which rests on the lower movable outlet 5.

For fixing the bottom movable outlet 5 on the stand 10, through holes are provided for inserting the studs of the stopper 11 into them after raising the bottom movable outlet 5 to the required level when opening the umbrella. The stopper 11 is suspended on a chain to a socket 5 and has the ability to hang on a chain at a socket 5 in the closed state of the umbrella.

All of the above claimed elements of the umbrella are parts of the umbrella frame.

Depending on the design, the frame can contain from four to eight spokes 8 and, accordingly, the same number of struts 9 spokes 8. The second end

each strut 9 is pivotally connected to each spoke 8 in the middle part between the ends of the spokes 8.

The knitting needles and struts are hollow from rectangular extruded profiles of constant cross section of an aluminum alloy DIN: AIMgSiO, F27 (ISO: 6005 AT6) or aluminum alloy DIN: AIMgSil F28 (ISO: 6082 Tb).

The hinge of each end of the spokes 8 and struts 9 in sockets 3 and 5 are wire rings 12 with twist 13, at least in one place. The wire ring 12 is located in the annular groove 14 of each of the sockets 3.5.

A day 13 of each wire ring 12 is located in the recess of each of the sockets 3, 5 in the middle between the spokes 8 or can be made inside the cavity of at least one of the spokes or one strut 9 of the spokes 8.

The chain 17, on which the stud of the stopper 11 is suspended, is dressed with one link 18 on the wire ring 12.

In the restrictive sleeve 6 there are two holes 15 for the passage or attachment of the rope 1.

In sockets 3, 5 there are holes 16 for the passage or fastening of the rope 1.

Knitting needles 8 and struts 9 knitting needles 8 have galvanic coating and / or wear-resistant powder polymer coating with appropriate heat treatment.

The width of the cross section of the spokes 8 and struts of the spokes 9 is 0.018 m, the height of the cross section of the needles 1 is 0.030 m, the wall thickness of the tubes is 0.0015 m.

The device operates as follows.

In the initial state, the umbrella is closed. The spokes 8 and struts 9 are located along the strut 10. The lower movable outlet 5 is in its lower position, the end of the rope 1 hangs freely below the lower movable outlet 5 5

umbrella.

To uncover the umbrella, the user manually pulls the end of the rope 1 downward along the strut 10. In this case, the rope 1 rolls along the rollers 2, 4 in sockets 3, 5, and the lower movable socket 5 automatically moves up along the strut 10 in the direction of the sleeve 6 Pull the rope 1 until the lower movable socket 5 is pulled to its upper position under the sleeve 6 above one of the holes in the rack 10 for inserting the stopper pin 11. In this case, without releasing the cable 1, the stopper pin is inserted into the hole of the rack 10. Then the rope 1 can be released. Socket 5, under the influence of the weight of the umbrella structure resting on it, presses the stopper pin 11 against the walls of the holes of the rack 10. Next, the umbrella is in the open state.

To close the umbrella, you must again pull the end of the rope 1 down along the strut 10 and raise the lower movable socket 5 above the stud of the stopper 11, after which the stopper 11 is removed from the holes of the rack 10. Then stop pulling on the free end of the cable 1 and release it. After that, the umbrella rapidly swings under the influence of the weight of the structure, which rests on the lower movable outlet 5. The lower movable outlet 5 rapidly rushes down, while along with the outlet 5, its roller 4 rushes down, which, rolling along with the roller 2 along the rope 1, again pulls the rope 1 in the initial closed position of the umbrella.

TECHNICAL RESULT: the design of the umbrella is simplified, less effort is required to raft it.
