Description

Automatic parasols {AUTOMATIC PARASOL}

The present invention relates to a parasol, and more particularly, to an automatic parasol that can easily and conveniently automatically fold and fold a parasol, and through which a parasol can be manufactured in large size.

In general, parasols are used to avoid sunlight or rain, like umbrellas, and these parasols are usually used independently or at a table on a beach or business place.

Conventional parasols, as shown in Figure 1, the support rod (1) that is directly inserted into the bottom of a sandy beach or the like or supported by a table, and the upper barrel (2) fixed to the upper end of the support rod (1), A lower barrel 3 which is inserted and coupled to the support rod 1 so as to be movable up and down, and a plurality of ribs 5 rotatably connected to the upper barrel 2 to support the sunshade cloth 4; A plurality of support rods 6 rotatably connected at both ends of the rod 5 and the lower barrel 3 and the support rod 1 are elastically installed to move the lower barrel 3. It consists of the stopper 7 which interrupts.

In the conventional parasol configured as described above, when the user grasps the lower barrel 3 by hand and pushes it upwards until the lower barrel 3 is caught by the stopper 7, as shown in FIG. Since the moving rod 5 and the awning cloth 4 are maintained in the unfolded state, while the parasol is unfolded as shown in FIG. 1 by pressing the stopper 7 by hand, the locking of the lower barrel 3 is released. Holding the lower barrel 3 in the state by hand to lower the support bar 6 is simultaneously moved to the lower because the unfolded rod 5 and the sunshade cloth (4) is folded.

However, the conventional parasol configured as described above has the inconvenience and difficulty of unfolding or folding the parasol manually while the user holds the lower barrel 3 by hand and pushes it upward or downward by applying force. In particular, in the case of a large parasol, there was a difficulty that the user could not easily open and fold the parasol alone.

In addition, the conventional parasol is limited to a predetermined size that the user can hold and hold the parasol manually by hand when using the hand as described above, so that the user can easily unfold or fold the parasol manually when manufacturing the parasol. There was a problem that can not produce a large parasol because it is limited to the size that can be produced.

On the other hand, in the conventional parasols, since the ribs 5 and the support rods 6 are made of a metal material, the ribs 5 and the support poles 6 are structurally easily rusted and broken. There was a problem in that deformation occurred because the elasticity to restore to the original state is weak when folded.

An object of the present invention is to invent the conventional drawbacks as described above, the user can easily and conveniently open and fold the parasol automatically and increase the user's convenience, through which the parasol can be made large It is to provide an automatic parasol.

Still another object of the present invention is to provide an automatic parasol that can prevent a plurality of rods and support rods constituting the parasol from being rusted, broken or deformed.

In order to achieve the above object, the present invention installs a screw rod that automatically stretches and folds the parasol while driving between the upper barrel and the lower barrel, and connects the motor driven in the constant region to the screw rod, and supplies power to the motor. And it is made of fiber reinforced plastic (FRP) that electrically connects the controller to control the drive, and also does not rust the rod and the support rod.
