Description

TECHNICAL FIELD The present invention relates to a windsock pole fixing base capable of installing, for example, a windsock pole for informing a pilot of emergency landing position wind information for a doctor helicopter (emergency medical helicopter) on any ground surface.

In the event of an accident, a windsock is used to notify the pilot of wind information such as wind direction and wind speed for safe landing when making an emergency landing of a medical helicopter at or near the accident site. Since the accident site where the helicopter will land is not fixed, the streamer must be able to be installed anywhere on the ground surface. Moreover, a large streamer is required to make it visible to the pilot of the doctor helicopter, and as a result, a large force is applied to the fixed base that supports the base end of the pole that attaches the streamer to the tip. It works, so it needs to be set up firmly against the ground and quickly in case of emergency.

A fixed base for a conventional streamer pole is a fixed tubular body that is formed by welding at one end in the longitudinal direction of a rectangular ground surface fixing plate that is fixed to the ground surface by the weight of a vehicle tire placed thereon. and a cylindrical stationary cylinder fixedly held by the fixed tubular body holding part, and the fixed tubular body is firmly fixed to the fixed tubular body holding part using a plurality of bolts. rice field. For this reason, not only does it take time and effort to fix the windsock pole to the fixed base, but it is also fixed to the ground surface fixing plate when not in use from the viewpoint of saving space during storage and transportation. It is necessary to separate the cylinder, and the work of removing this fixed cylinder is also troublesome because it is necessary to remove a plurality of fixing bolts one by one.

In addition, Patent Document 1 discloses an installation mechanism for installing a streamer pole on a fence. The installation mechanism, which installs a streamer pole on a fence at a specific position, cannot be used.

As shown in FIG. 1, when the wheel T of the vehicle is placed on most of the remaining portions of the ground surface fixing plate 41 to which the pole fixing base F is not fixed, the large weight of the vehicle causes the ground surface fixing plate to move. 41 is firmly fixed to the ground surface G. The pole is made of carbon fiber and has a telescopic structure that makes it easy to handle when not in use.

As shown in FIGS. 4 to 9, the pole fixing base F is placed at one end in the longitudinal direction of the rectangular ground surface fixing plate 41 along the width direction of the ground surface fixing plate 41 at a predetermined interval. a pair of standing fixed plates 1 made of metal plates fixed by welding, and a fixed cylinder whose arrangement position is fixed between the pair of standing fixed plates 1 and which can move up and down within a predetermined range in the vertical direction. It is composed of a body D and a cylinder movement restricting member 31 for determining the arrangement position of the lower end of the fixed cylinder D with respect to the ground surface fixing plate 41 and fixing it. The cylinder movement restricting member 31 is formed of a square-shaped short frame into which the lower end portion is fitted so that the fixed cylinder D does not slightly move in all directions. The pair of standing fixed plates 1 are bent outward at right angles at their lower ends, and the bent portions are welded to the ground surface fixed plate 41 . The flat plate-shaped ground surface fixing plate 41 is a slip pipe-shaped anti-slip plate that increases its own bending strength and also serves as reinforcement for preventing the wheel T from slipping when the wheel T of the vehicle is placed thereon. The material 42 is formed on both ends in the width direction over the entire length in the longitudinal direction, and the end on the side where the pole fixing base F is fixed along the longitudinal direction of the ground surface fixing plate 41 is manually A handle 43 is provided to allow it to be held and transported.

They are formed facing each other. The width of each slide guide slot 2 corresponds to the outer diameter of the pair of slide fulcrum shafts 14 having a circular cross section. At the upper end of each slide guide slot 2, each assembly slot 3 facing in opposite directions is formed orthogonally, so that the combined shape of both slots 2 and 3 is an inverted L shape. None. The width of the elongated assembly hole 3 is wider than the width of the elongated slide guide hole 2 in order to facilitate the assembly work. Further, the pair of standing fixing plates 1 can be manually operated to facilitate the assembly/separation work when the fixing cylindrical body D is assembled/separated from the pair of standing fixing plates 1 . The upper free end is made of a slightly bendable metal plate. As described above, since the pair of standing solid plates 1 alone has low rigidity, when the fixed cylindrical body D is assembled/separated from the pair of standing solid plates 1, the pair of sliding fulcrum shafts 14 is the center. Spacer rods 4 arranged between the fixed standing plates 1 and small bolts B with hexagonal holes arranged outside the fixed standing plates 1 are placed at a position where the fixed cylinder D which rotates through the rotation does not interfere with each other. By being connected to each other, the rigidity of the pair of standing fixing plates 1 as a whole is enhanced. As a result, the portion of the space between the pair of fixed upright plates 1 opposite to the spacer rod 4 can rotate about the pair of slide fulcrum shafts 14 without interference of the fixed cylinder D. A non-interference space 18 is formed.

As shown in FIGS. 4 to 6, the stationary cylinder D has an intermediate portion (a portion near the lower end) between the longitudinal central portion and the lower end portion of a cylindrical cylindrical body 11. A ring-shaped increased diameter portion 12 for partially increasing the outer diameter of the main body 11 is integrally provided, and the inner surfaces of the pair of standing fixing plates 1 are provided on the opposing portions of the outer peripheral surface of the increased diameter portion 12 . Inner surface guide bodies 13 which are in sliding contact or close to each other protrude along the radial direction of the cylinder body 11, and furthermore, on the tip surface of each inner surface guide body 13, each slide guide of the pair of standing fixed plates 1 is provided. A pair of slide fulcrum shafts 14 each having a circular cross section and inserted into the long hole 2 protrude in the radial direction. As shown in FIG. 8, the inner width _W1 of the pair of upright fixed plates 1 is slightly larger than the outer dimension _W2 of the pair of inner surface guides 13 of the fixed cylindrical body D. As shown in FIG. A line connecting the centers of the pair of slide fulcrum shafts 14 respectively provided at the opposed portions of the cylindrical body 11 of the fixed cylindrical body D is the tilting fulcrum axis _C1 of the fixed cylindrical body D. As shown in FIG. As shown in FIGS. 4 and 9, a connection collar 16 having a tapered concave conical surface 15 is fitted on the upper end of the cylindrical main body 11 . The tapered concave conical surface 15 of the connection collar 16 is fitted to the fixed cylindrical body D by fitting the tapered conical surface 51 of the outer periphery of the connection collar 52 fitted on the pole unit _P1 at the proximal end of the pole P. It is the part that connects the pole P to the pole P integrally.

A fixed cylindrical body D is fitted between the pair of standing fixed plates 1 of the pole fixing base F in the ground surface fixed plate 41 to prevent the fixed cylindrical body D from being slightly moved in all directions. A cylindrical body movement restricting member 31 is provided, and a movement restricted body 53 at the lower end of the pole P is fitted on the inner side of the cylindrical body movement restricting member 31 to restrict the fine movement of the lower end of the pole P. A small pole movement restricting member 32 is concentrically fixed to the cylinder movement restricting member 31 .

In order to determine the arrangement position of the fixed cylinder D between the pair of standing fixing plates 1 fixed to the ground surface fixing plate 41 and arrange it vertically, as shown in FIG.

In order to enable the assembling operation described above, the projection length of the pair of slide fulcrum shafts 14 provided in the radial direction facing the outer peripheral surface of the cylinder main body 11 of the fixed cylinder D is made as short as possible. If it is difficult to perform the above operation, remove the spacer rod 4, disconnect the pair of standing fixing plates 1, and spread the upper end side of each standing fixing plate 1 outward by hand. , easy to work with.

When the fixed barrel D is lowered in this state, each slide fulcrum shaft 14 of the fixed barrel D is guided by the long slide guide hole 2 and slid downward, and the lower end portion of the fixed barrel D is moved to the cylinder. The position of the stationary cylinder D relative to the ground surface fixing plate 41 is determined by being fitted inside the body movement restricting member 31 , and each slide fulcrum shaft 14 of the stationary cylinder D is aligned with each of the erecting stationary plates 1 . Since each slide fulcrum shaft 14 and each slide guide elongated hole 2 are engaged with each other by being inserted through the slide guide elongated hole 2 , the stationary cylinder D is perpendicular to the ground surface fixing plate 41 . fixed position. This state is the use state of the pole fixing base F as shown in FIGS. 3 and 11(a). A small bolt B is screwed through a spacer ring 17 to prevent each slide fulcrum shaft 14 from slipping out of the long slide guide hole 2 .

On the other hand, after use, in order to fold the fixing cylinder D standing vertically with respect to the ground surface fixing plate 41 for transportation or storage, as shown in FIGS. When the pair of small bolts B fixing the fixed cylinder D to the pair of standing fixing plates 1 is loosened and the fixed cylinder D is lifted up to the upper end, the lower end of the fixed cylinder D When the fixed cylinder D is released from the body movement restrictor 31 and tilted around the tilting fulcrum axis C ₁ of the pair of slide fulcrum shafts 14, the upper end of the fixed cylinder D moves to the ground surface fixing plate. 41 and is folded. As described above, according to the present invention, in order to change the pole fixing base F from the use state to the folded state, it is only necessary to lift and tilt the fixing cylinder D without removing a plurality of troublesome bolts. , the folding operation is extremely easy. If necessary, by tightening the two small bolts B that have been loosened at the pair of slide fulcrum shafts 14, the fixing cylinder D can be fixed to the pair of upright fixing plates 1 to facilitate transportation. At times, the fixed cylinder D does not rattle. In the partial enlarged views of FIGS. 10(a) to 10(c), only the solid line portion is enlarged and the two-dot chain line portion is not shown.
