Parasols {PARASOL}

The present invention relates to a parasol, and more particularly, to a parasol in which the user can arbitrarily adjust the angle and length while improving the parts, thereby reducing the number of parts and preventing malfunctions.

As shown in FIG. 1, a parasol 1 is generally installed on a beach or an outdoor business place for the purpose of avoiding sunlight and rain, and maintains the shape of a parasol cloth 2 and a parasol cloth 2. It consists of a frame (3) for the installation of the frame and the frame to. The parasol 1 is configured to be foldable for easy storage, transport and use, and for this purpose, the frame is slidable to a plurality of main frames 4 and one end to a support 3 radially installed on the parasol cloth 1. The other end may be rotatably coupled to the foldable opening (5) to be installed so as to be folded guide frame (6) supporting the parasol cloth (2) rotatably coupled to the main frame (4).

In order to maintain the unfolded state of the parasol 1, the supporter 3 is provided with a locker 7 which is hooked to the lower end of the folding device 5 and fixes the folding device 5 in a protruding manner.

On the other hand, it is necessary to vary the height of the parasol (1) according to the conditions, such as the installation space of the parasol (1), for this purpose, the auxiliary column (8) is further employed at the lower end of the support (3). The interior of the support (3) is made of a hollow shape so that the auxiliary support (8) is installed therein, the fixing hole (3a) is drilled in the support (3) for the coupling of the auxiliary support (8), The strut 8 is provided with a fixing protrusion 8a that is fitted into the fixing hole 3a.

In the figure, reference numeral 8b is a spring that elastically supports the fixing protrusion 8a in a direction that is fitted to the fixing hole 3a.

The state of use of the parasol according to the prior art is as follows.

The parasol 1 folds so that the folding guide frame 6 is folded to form a straight shape when storing and carrying, and stores and carries the auxiliary column 8 separately from the main body of the parasol.

On the other hand, when using the parasol (1) raise the folding device (5), the folding device (5) slides along the support (3) while the folding guide frame (6) rotates with the main frame (4) parasol cloth (2) is unfolded. When the locker 7 is locked to the lower end of the folding device 5 by moving the folding device 5 so that the locker 7 is caught at the lower end of the folding device 5, the parasol cloth is maintained in an unfolded state.

After unfolding the parasol (1) in this way can be used to combine the supporting column (8) to the support (3), the auxiliary support (8) is inserted into the lower end of the support (3) fixed to the fixing hole (3a) After fitting the projection (8a) to the auxiliary column (8) to the support (3), it is inserted into the sand, or installed on the table to use.

When folding to store the umbrella (1) in the unfolded state, push the locker (7) into the support (3) to release the locking force, then move the folding mechanism (5) to the lower side of the support (3) folding guide frame (6) is folded and the parasol (1) is folded.

However, the parasol according to the prior art has the following problems.

The locked state of the parasol 1 is maintained by locking the locker 7 to the fold 5, but since only one locker 7 is formed and its position is not variable, the angle of the parasol 1 may be constant. There is no choice but to. That is, since the angle of the parasol 1 can not be arbitrarily adjusted, there is a disadvantage in that the parasol 1 cannot be used when the parasol 1 is unfolded at a predetermined angle due to the limitation of the installation space.

In addition, when operating the locker (7), the lever and the like to fold the parasol, the user's fingers are felt, the finger is caught between the support (3) and the fold (5) is also injured.

In addition, since the auxiliary holding 8 must be stored and carried separately from the parasol body, inconvenience caused by storage, carrying, and loss occurs, and only one fixing hole 3a and a fixing protrusion 8a are formed, so that they are mutually separated. It is cumbersome to match them together. In addition, since the auxiliary column 8 is also coupled only to a predetermined position (length) on the shore, there is a disadvantage in that the overall length of the parasol cannot be adjusted.

In order to solve this drawback, the Korean Utility Model Registration Application No. 1996-38829 has been proposed a folding mechanism of the parasol folding.

As shown in FIG. 2, the folding mechanism fixing structure of the pre- filed parasol is inserted and slid into the strut 3, and the elastic piece 11 is formed through a plurality of cutouts from the upper end to the central part, and the outer circumferential surface at the bottom thereof. A screw portion 12 is formed on the upper end of the stretchable piece 11, the holding portion holding grip portion (10a) formed with a holding gripper (10); It is installed to be coupled with the holding gripper 10, the screw portion 21 is formed on the inner peripheral surface of the lower portion to be screwed with the screw portion 12 formed on the outer peripheral edge of the holding gripper 10, the locking projection 22 in the center of the inner peripheral surface It is formed, it is characterized in that the fixing structure body consisting of the rotating body 20, the narrowing portion 23 is formed from the locking step 22 to the upper end.
