Description

[Detailed Description of the Invention] This invention consists of a pillar fixedly erected in the vertical direction, and wings made of foldable fabric or plastic sheet that are pivotally connected to the top of the pillar and become square when opened. , relates to a parasol whose wings extend outside a balcony or other area to provide shade from the sun or rain.

Conventional parasols are large umbrellas used on the coast to shade the sun, and cannot be used on balconies because the pillars of the umbrella are stuck deep into the sand. Also, although it is large, it is an umbrella, so it only shades a circular area around the pillar, and even if it is placed on a balcony, only half of the circular area can protrude outside the balcony. The area is small.

Therefore, in the present invention, almost the whole of the square wings mentioned above protrude outside from the balcony, and the balcony can be used as a sunshade.
I tried to effectively protect myself from the rain, and the following is as follows.
The invention will be described with reference to an illustrated embodiment.

Reference numeral 1 denotes a pillar, which consists of a main pipe 1a with a rubber cap 2 attached to its upper end, and an adjustment pipe 1b that fits into the main pipe 1a and partially protrudes from the lower end of the main pipe. The adjustment tube 1b has many holes in the vertical direction through which the bolts 3 pass, and the length of the column 1 is determined by which hole in the adjustment tube matches the hole in the main tube and the bolt 3 is passed through. The height should roughly match the height from the floor to the ceiling of the balcony.

Reference numeral 4 denotes a pedestal at the lower end of the column, from the center of which a bolt 4' stands up rotatably, and the upper part of the bolt 4' is screwed into a female thread provided on the inner periphery of the lower end of the adjustment tube 1b. If necessary, make a horizontal hole at the bottom end of the bolt so that a thin rod or the like can be passed through it. This bolt 4' functions as a screwdriver, and when the length of the pillar 1 is roughly adjusted to the height from the floor to the ceiling of the balcony as described above, the bolt 4'
is turned to increase the amount of protrusion from the lower end of the adjustment tube, thereby pressing the lower surface of the pedestal 4 to the floor and the rubber cap 2 at the upper end of the column to the ceiling, respectively, and fixing the column 1 in the vertical direction on the balcony and standing it up. Place the pillars on the outside of the balcony as much as possible.

A horizontal arm 5 is fixed to the lower end of the adjustment tube, and a vertical screw hole is provided at the tip of the arm 5, and a bolt 5' is screwed through it. A hole or recess 4a is provided to receive the lower end of the bolt 5', and the bolt 5' is turned so that the lower end enters the desired recess 4a. This bolt 5' is used to prevent the column from collapsing due to the adjusted length changing when the column 1 rotates, and to prevent the column from falling over due to changes in the direction in which the wing protrudes from the veranda, which will be described later. Helps prevent.

A bearing piece 6 projects laterally from the upper end of the main pipe 1a, and a support plate 8 provided at the center of one long side 7a of a rectangular wing 7 made of a plastic sheet, cloth, etc. can be raised and lowered around a horizontal axis 8'. pivot. The support plate 8 has two bones 9a attached to the wings with their tips facing each end of the long side 7a, and two bones 9b attached to the wings with their tips facing each end of the other long side. and one central bone 9c with the center of the other long side 7b attached to the tip.
and are pivotably connected in the same plane as the plate surface of the support plate. Only the central bone 9c may be fixed to the support plate. When the bones 9a, 9a along the long side 7a protrude from both sides of the support plate in a straight line with each other, they are restricted by stoppers so that they do not open any further.

For this purpose, the support plate 8 is made of plastic or the like to have a U-shaped cross section, and the above-mentioned bone is pivoted between the two pieces 8a, 8a of the U shape, and the bearing piece 6 is attached to the thick part 8b from which the two pieces 8a, 8a protrude. This thick portion 8b also serves as a stopper for the bones 9a, 9a.

The bones 9a, 9b, and 9c are thin hollow or solid rods made of plastic or metal, and a first operating barrel 10 is fitted to the center bone 9c so as to be slidable and adjustable. When the first operation tube 10 is moved along the central bone toward the support plate 8, each bone 9a rotates and opens due to the connecting rods 11, 11, and accordingly, the bones 9a 9b is also opened, and the wings 7 are stretched tightly into a rectangular shape, and when the wing 7 is moved in the opposite direction, the bones 9a, 9a are pulled by the connecting rods 11, 11, and the bones 9a are aligned approximately parallel to each outside of the bone 9c, and the The bone 9b is pushed by the bone 9a so that the wing 7 is folded.

Therefore, one end of the connecting rod 11 is pivotally connected to the bone 9a, and the other end is pivotally connected to the first operating tube 10 at right angles to the plane of the wing 7.

Further, a second operating barrel 12 is slidably fitted along the pillar 1, in this embodiment the main pipe 1a, and the second operating barrel 12 and the first operating barrel 10 are connected by a connecting rod 13. This second operation cylinder 12 descends along the main pipe 1a and pulls the blade 7 toward the pillar 1 with the connecting rod 13, gradually making it vertical, and conversely, by rising along the main pipe, the blade is pushed up with the connecting rod 13. , gradually approach the horizontal level.

In order to fix the operation tube 10 at any adjustment position along the bone 9c and the operation tube 12 at any adjustment position along the main pipe 1a, a split groove 14 is provided in each operation tube, and an eccentric device having a lever in the split groove 14 is provided. Pivot 1 with cam 15
6, when the cam 15 is rotated by moving the cam 15 in one direction with the lever 17, the cam 15 comes into pressure contact with the outer circumferential surface of the bone 9c or the main pipe 1a, fixing the operation tube immovably by frictional force,゜When the cam 15 is rotated, the cam separates from the bone or the outer peripheral surface of the main pipe 1a,
The operation cylinder can be moved along the bone 9c or the main pipe 1a (Fig. 6).

In use, the pillar 1 is fixed vertically between the floor and ceiling of the balcony as described above. Then the first
Operate the operation tube 10 to open the wings 7, fix the first operation tube 10 to the bone 9c with the wings open, and then push up the second operation tube 12 along the main pipe to set the wings 7 at the desired angle. and secure it to the main pipe.

As a result, pillars 1 can be erected on the balconies of rented condominiums and public housing without damaging the building, and wings 7 can be made to protrude outside the balcony to provide sunshade and rain protection for the balcony, and chairs and tables can be placed on the balcony. can be used as a living space for meals and social gatherings. Also, when not in use at night or during a storm, the wings 7 can be folded up.

As mentioned above, beach umbrellas have traditionally been used as sunshades on the coast, but in order to be able to use them on balconies, they require a support device to stand them up, and even then they do not fall off when blown by the wind. There is a danger of this happening, and the area that can be shaded from the sun and rain is extremely limited.

In addition, some shops have eaves extended from the storefront to protect against the sun and rain, and can be retracted when necessary, but this requires construction work to be installed on the building frame. It is not easy to install, and it cannot be installed in rented condominiums or apartments because it will damage the building.

The present invention solves the above-mentioned problems and can be installed without damaging the building with simple operations.This invention allows the balcony to be elevated from a mere place to dry futons and laundry to a living space, and moreover, it can be used as a home for owners. , which has the revolutionary feature of being able to be used regardless of the rental status.

Note that there is a depression or hole 1 on the inner periphery of the first operating barrel 10.
8 is provided to house a spring 19 and a ball 20 pressed against the outer periphery of the bone 9c by the spring 19,
A hole or a recess 21 into which a part of the ball 20 fits is provided in the bone 9c at a position where the blade 7 is fully opened by moving the operation cylinder 10 and a position where the blade 7 is folded. A click stop mechanism may be used in conjunction with the aforementioned cam 15, or may be used alone to restrict full opening and folding of the wings.

Similarly, there is a ball 20 on the inner periphery of the second operating barrel 12 that is pressed against the outer periphery of the main pipe by a spring, and the main pipe 1a has a plurality of holes or recesses 21 into which parts of the balls fit into a plurality of positions in the vertical direction. A stop mechanism may be used in combination with the cam 15 or provided independently to regulate the angle of inclination of the blade 7 with respect to the pillar in multiple stages.

In addition, pulleys are attached to the bearing plate 6 and the support plate 8, respectively.
It is also possible to hang a rope with one end attached to the first operation tube 10 along the pillar 1 via the above-mentioned pulley, and to open the wings by pulling this rope downward.

Furthermore, if a support device such as a tripod is provided below the pillar 1 so that it can stand on its own, it can be used as a parasol to provide shade on the coast, in the mountains, or in the fields.
