    Mechanism for regulating the direction of rotation of a parasol
    Patent
    Technical range
    The present invention relates to a turning mechanism for the parasol surface of a parasol.
    Technical background
    With the traditional parasol, the angle of inclination of the parasol surface is usually regulated via an inclination mechanism in the parasol. The inclination mechanism comprises an upper and lower plug, wherein a plug is used as a spindle. At the same time, a push button is provided in the upper plug. A slot is provided in the lower plug. By pressing the push-button, different toothing positions of the upper plug with the lower plug can be regulated, in order to regulate the alignment of the parasol surface and thereby fulfill the purpose of the parasol. However, with this tilting mechanism, only the tilt angle of the parasol surface can be regulated. It does not allow horizontal rotation of 360 degrees. With the change in the angle of light from the sun, the parasol stand must be moved in order to obtain an optimum position against the sun. For this reason, the use is very complicated.
    To solve this problem, a rotating mechanism for rotating parasol surfaces was made with the patent No. 200420023521.0, with the aim of allowing a 360 degree rotation of the parasol surface relative to the ground. This mechanism essentially comprises a bearing shell and an axle sleeve, each of which is mounted in the two parasol tubes. An axle is fitted in the bearing shell. A connecting shaft between the bearing shell and the shaft sleeve is fitted through the bearing shell, the shaft and the shaft sleeve and forms a unit with the shaft sleeve. The connecting shaft, the bearing shell and the shaft move together. The lower tube is coupled to the rotary knob via a connecting mechanism, so that synchronous rotation is possible. However, this mechanism is structurally complicated and expensive.
    Invention of the invention
    In order to solve the technical problems described above, the present invention solves the technical problem which exists according to the state of the art through a structurally simpler and more user-friendly rotating mechanism of the parasol surface.
    The technical solution of the present invention with respect to the technical problems illustrated above goes as follows: A pivoting mechanism for the parasol surface of a parasol, comprising a handle between the upper and the lower parasol tube, characterized in that in the interior of said upper parasol tube a bearing shell is attached to one end, a connecting sheath is provided at the end in the interior of said lower parasol tube, a bearing is fitted in the bearing shell, a connecting shaft runs through the bearing shell and coordinates dynamically with the bearing shell on the one hand and lower static. The lower coupling ring comprises the connection casing. A bolt is pulled through the bolt hole located below the connecting shaft and connects the bolt hole in the connecting casing with the sliding slot in the lower coupling ring so that this connecting axis rotates synchronously with the connecting casing and the lower coupling ring. The lower coupling ring is toothed with the bearing shell. The upper parasol tube can rotate synchronously with the handle via a connecting mechanism.
    For improvement, the lower coupling ring with the bearing shell is toothed with each other by an annular gear. In addition, a coil spring is provided between the lower coupling ring and the positioning ring, which is attached outside to the lower parasol tube, for restoring the original position. A pressure mechanism is provided in the handle that is opposite to the lower coupling ring and coordinates with it.
    For improvement, the aforementioned connecting mechanism means that a thickening is provided at one end of the handle, on which a positioning slot is provided. This positioning slot coordinates with the elastic strip, which is located inside the outer bowl, and thereby realizes the connection. The elements of the crank inside the outer bowl are firmly connected to the upper parasol tube.
    Finally, the said handle is connected to the pressure sleeve by a screw thread. The above-mentioned bearing shell is attached to the upper parasol tube with a hollow bolt. The illustrated connection sleeve is firmly connected with a positioning ring and a pin to the lower parasol tube.
    The advantages of the present invention are that the entire structure is simpler than the already known technology. The use is easier. The structure is reasonable and practical. The production costs are low and more consumer friendly.

    The present invention will be further elucidated with reference to the exemplary embodiments shown in the following figures.
    The present invention can be applied to different locations of the straight parasol tube according to needs. Here the mounting under the crank is given as an example. The so-called upper and lower parasol tube thus mean the middle and the connecting tube of the parasol, respectively.
    The concrete embodiment as shown in figure 1 and figure 2, the rotation mechanism for the screen surface of the parasol consists mainly of bearing shell 4, connecting shaft 1, lower coupling ring 15, connecting sleeve 5, coil spring for restoring the original position 16, handle 7 and the like:
    The bearing shell 4 is connected to the upper parasol tube 2 by a hollow pin 3, there is an opening in the middle of bearing shell 4. With the aid of this opening, the connecting shaft 1 of the bearing shell 4 is enclosed. For positioning, bearing shell 4 cooperates with the connecting shaft 1 to prevent fluctuations. The bearing shell 4 and the connecting shaft 1 coordinate dynamically with each other. A spindle 14 is locked at one end of bearing shell 4. Simultaneously, at the end of this bearing shell 4, teeth are uniformly arranged around the concave ring, which teeth lead to an annular gear.
    The connecting shaft 1 is an element such as an axle which connects the bearing shell 4 and the connecting sleeve 5 together. At the front end of the connecting shaft 1 a thickening 11 is provided for locking. This connecting shaft 1 is statically related to the shaft 12. Below bolt shaft 1 there is a bolt hole which connects to the casing 5.
    The connection casing 5 is placed under the connection shaft 1. At the end of connection sheath 5, an axis shoulder contacts the inner ring of axis 14. This shaft shoulder does not touch the outer ring and the bearing shell 4. A bolt hole is provided on the connecting casing 5, which bolt fits at the bolt hole in the connecting shaft 1 and the sliding slot on the lower coupling ring 15. The connection between connection casing 5, connection shaft 1 and the lower coupling ring 1 is effected by the bolt 6 being guided through the sliding slot on the lower coupling ring 15 and the bolt hole on the connection casing 5 as well as the hole in the connection shaft 1. For this reason, the connecting shaft 1, the connecting sleeve 5 and the lower coupling ring 15 rotate synchronously. A pin hole is provided on the connection casing 5, so that the connection casing 5 can be attached to the lower parasol tube.
    An annular gear is fitted to the lower coupling ring. In this way, bearing shell 4 and the lower coupling ring 15 are two different gear wheels, the number of teeth and the tooth shape of which are identical.
    The handle 7 is an important element for the realization of the rotation and positioning. A thickening 12 is provided at one end of handle 7. A positioning slot is placed in the bulge 12. This positioning slot coordinates with the elastic positioning strip inside the outer bowl to establish a connection. Under the cooperation of thickening 12 and the sliding slot, the handle 7 and the outer cup 9 can rotate simultaneously. The handle 7 and the pressure element 13 are connected to each other via a screw thread. The pressure mechanism 13 and the handle 7 move synchronously.
    During assembly, the pressure mechanism 13 is placed on the upper parasol tube 2. The connecting shaft 1 is covered with the bearing shell 4. The shaft 14 is mounted below the bearing shell 4. They are then installed in the connection casing 5. Then the connection casing 5 of the lower coupling ring 15 is covered. The bolt hole in the connecting shaft 1 as well as the hole in the connecting casing 5 are adapted to the sliding slot in the lower coupling ring 15 and fixed to each other by a bolt 6, so as to form a unit. The bearing shell 4 is fixed by a pin 3 with the upper parasol tube 2. The coil spring for restoring the original position 16 is covered with the connection casing 5 and the lower coupling ring 15. At the same time, the lower parasol tube 18 is covered by the positioning ring 8. The connecting casing 5 is inserted into the lower parasol tube 18. Connection pin 5, positioning ring 8 and lower parasol tube 18 are attached to each other by a pin 17. Said positioning ring 8 and the coil spring 16 form a mechanism for the automatic reset. The handle 7 is pulled over the lower parasol tube 18. The pressure mechanism 13 is then screwed onto it. The handle 7 is pulled down and the lower parasol tube 18 is rotated. The positioning of the positioning slot on the handle 7 is adjusted so that it coordinates with the elastic positioning strip in the interior of outer bowl 9. The crank 10 is finally installed. The crank 10 in the outer bowl 9 must be firmly connected to the upper parasol tube 2.
    The positioning of the parasol can be regulated on the one hand by the tilting mechanism to regulate the angle of the parasol surface. On the other hand, with the aid of the present invention, the positioning of the parasol surface can be controlled by a rotation through 360 degrees. The bearing shell 4 is slid over the connecting shaft 1. As a result, the bearing shell 4 in the uncoupled state of the lower coupling ring 15 can rotate synchronously with the parasol surface. Because the connecting sleeve 5 is attached to the lower parasol tube 18, the lower coupling ring 15 is fixed by a bolt 6 and a connecting sleeve 5 to the connecting shaft 1, the lower connecting ring 15 can never rotate. During use, the handle 7 is pushed down by hand, so that the pressure mechanism 13 can push the lower coupling ring downwards. The coil spring 16 is depressed, the bearing shell 4 releases from the lower coupling ring 15 (Figure 1 becomes Figure 2, Figure 3 becomes Figure 4). At this time, the handle 7 is rotated to thereby rotate the outer bowl 9 and the crank 10. Because the crank 10 is firmly connected to the upper parasol tube 2, the parasol surface can thereby be rotated. After the desired position has been reached, the handle 7 can be released. With the aid of the spring force of coil spring 16, the coupling ring 15 and the bearing shell 4 go into teeth again, in order to be ready for the next regulation.
