Description

In the present invention, when necessary or at a constant wind speed, the umbrella part of the parasol moves horizontally to open and close, even in fully automatic and manual operation for safety. Regardless of whether it is a vertical T-shape or not, the present invention relates to a horizontally movable open / close-type large parasol characterized by a structure in which the central portion of the support column is a shaft axis and the direction of the entire parasol can be rotated.

Conventionally, parasols have been mainly used for awnings, rain protection, or decorations such as restaurants. Therefore, small and large parasols are used by installing them when necessary and removing them when they are not needed.

The manufacturing method of these small and large parasols is also made up of an umbrella type, which opens and closes up and down.

However, recently, due to global warming, the outside temperature is extremely high throughout the year, and from July to September every year, young people and elderly people suffer from sunstroke and are becoming a social problem.

For this reason, unlike large playgrounds, demand for ultra-large umbrellas such as small playgrounds, rest areas, or workplaces, storage rooms, and parking lots in a narrow sense is increasing.

In addition, when using sunbathing and rain prevention suddenly when using small playgrounds, kindergartens, public halls, etc., and when other large parasols are suddenly unnecessary due to volleyball and softball in sunny weather Because the main pillar of the center is in the center, when using the square, there are things that are very troubled by the presence of this main pillar, and there are unnecessary aspects, so it is inconvenient to remove the parasol from the spot.

All conventional large parasols are umbrella-type opening and closing types. 2. There is a main pillar in the center of the parasol. 3. In the case of the umbrella type up / down opening / closing type, it is difficult to produce a large umbrella. There are disadvantages such as.

As an improvement measure, the present invention proposes the horizontally movable large-sized parasol that is the present invention.
Patent Publication 2002-004644 Patent Publication No. 11-266990 Utility model publication 07-034713 Registered Utility Model No. 3071733 Registered Utility Model No. 3071714

All of the conventional large umbrellas are structured to open and close by pushing up and down like umbrellas. Accordingly, there are the following problems.
Since the main pillar is in the center and the large parasol is T-shaped, the area directly under the parasol interferes with the iron pillar, and there is a drawback that the field cannot be used freely for use in playgrounds, workplaces, parking lots, etc.
Larger size is difficult than a certain limit.
While using a large parasol, there was a problem that only the parasol part could not be closed, and all the parasols and even the steel pillars could not be temporarily moved and re-installed.

The main feature of the present invention is that the umbrella part of the parasol moves horizontally when it is necessary or at a constant wind speed for safety, even in fully automatic and manual operation, and is easy to temporarily open and close. became.

Regardless of whether the supporting parallax of the present invention is an L-shaped or vertical T-shaped halfway, a structure that can rotate the direction of the entire parasol using the central part of the supporting column as a shaft by a shaft. If the main pillar is L-shaped, it can be used as a storage space and a parking lot under the parasol.

In addition, when the large parasol can be made larger and the parasol is temporarily unnecessary, only the parasol is closed first. If you still need it or want to move it, you can rotate the entire large umbrella 180 °, and you can easily use it in sudden weather and rain without removing it.

Products that are easy to install and use can be realized without compromising the overall shape of conventional large umbrellas.

FIG. 1 is a front view of an embodiment of the device of the present invention. The umbrella shows 1 and the upper main pillar 3 and the hoisting machine 2 can move up and down the umbrella parasol itself. It can be rotated with the bolt 4 of the main pillar center shaft, and 7 and 5 are the lower main pillars (fixed parts), 6 is the electric control controller BOX, and 9 is the rotation. It is a roller to support.

2 is a left side view, FIG. 3 is a right side view, FIG. 4 is a rear view, and FIG. 5 is a plan view. 1 to 9 are the same as in FIG.

FIG. 6 is a bottom view, 8 is a rotating horizontal column, and 5 is a fixed main column. 12 is a two-wheel motor, 13 is a pulley, 14 is a support rib, 15 is a wire fixing bracket, 16 is a wound wire, and 17 is a feed wire opposite to 16.

FIG. 7 is a cross-sectional view of FIG. 7 in FIG. 7 shows a steel frame portion as one of the umbrella portions of the moving parasol, and 19 is a balance weight for controlling the total weight of moving up and down the entire umbrella portion of the 10 frame (arch). This reduces the overall weight of the parasol and the 20 wire hoist has the advantage of significantly reducing the force. Reference numeral 18 denotes a shaft capable of rotating the parasol by 360 °. Reference numeral 21 denotes a power transmission cable that is input from underground. 4 and 6 are the same as those in FIG.

FIG. 8 corresponds to claim 2 and is a view of the entire parasol viewed from the bottom. 10 is a parasol framework, which is the same as 11 but 11 is fixed and does not move. A-1 and A-2 take out the horizontal arm from the main column, take out the steel material by welding and use it as a fixed base, attach the pulley in 4 parts of parasol, and play the role of pulling and pushing the wire. 12 is the length of the fixed position which a parasol opens, and it fixes with a tension wire. 12, 13, 16, and 17 are the same as those in FIG.

FIG. 9 shows a framework of a parasol, in which a wire is drawn by 12 motors and a quadruple parasol is closed. The frame of 11 is fixed at the center with 2 nuts of 23, and 12 motors are attached to it. By rotating this motor forward and backward, through 13 pulleys, 10 moves left and right, The parasol tent opens and closes.
The mounting portion from the main column of the 10 moving frames has one bolt and nut.

FIG. 10 is the part of claim 3, and the connection between the fixed part of the main pillar 3 and the moving 10 parasol frame is fixed by 24 shafts, and by using 25 radial bearings, it can be opened and closed more horizontally. The structure is easy to move. 26 is a wire stopper.

FIG. 11 is a diagram of the motor 28. This motor has a shaft at the center, and it has adopted the construction that wires 16 and 17 can be attached to the shafts on both sides. The 16 wires are the lower volume, the 17 wires are the upper volume, and the wire winding shaft 27 is further grooved so that the wires can be wound on average, and the winding and feeding of the wire are simultaneously performed by rotating the motor in one direction. The construction shown in FIG. 10 has the advantage that the motor can be a small, low-cost, energy-saving type.

With the invention of the large horizontal umbrella that can be opened and closed this time, the width of the parasol can be manufactured to 10-12m, it is easy to rotate and store when unnecessary, without worrying about the wind speed, and the super large parasol can be installed and installed. Become.
It is possible to use small playgrounds such as kindergartens, nursing homes, gateball grounds, public halls, and permanent parasols in small squares. Industrially, they can be used for temporary storage of goods, parking lots, restaurants, beer halls, and golf courses. In addition, the large arch-shaped parasol, which is different from the four-pillar type four-sided tent, also has a good design. By using the color for the parasol, in event venues, outdoor restaurants where people gather, and service facilities, There is also an advantage that an advertising appeal effect is added.
