  BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a front view showing an embodiment of a handrail support column according to the present invention. The handrail support column 10 has an upper support column 1 fitted to a hollow lower support column 2 so as to be freely inserted, and the upper support column 1 is fixed to the lower support column 2 by two insertion elements 3 which are screws. The lower support column 2 is a structure in which a sheath pipe S projecting upward from the base plate P is inserted in the vicinity of the lower end and fixed by a screw B1, and the base plate P is fixed and fixed to the ground surface G by an anchor bolt B2. is there. The upper support column 1 is provided with a concave groove 4 continuously in the vertical direction on the side through which the inserter 3 is inserted, and an attachment hole 5 is provided at the bottom of the concave groove 4. A synthetic resin cap 7 is attached to the upper end of the lower support column 2. An attachment portion 101 is provided at the upper end of the handrail support column 10, and a handrail member is attached using the attachment portion 101.

  FIG. 2 is a cross-sectional view of a portion where the inserter 3 is attached. The upper support column 1 and the lower support column 2 are both formed from an extruded shape of an aluminum alloy so as to have a substantially circular cross section. A hollow portion 21 is provided inside the lower support column 2, and the upper support column 1 is provided in the hollow portion 21. It is inserted. Two screw holes 11 are provided on the inner surface of the upper support column 1, and four screw holes 22 are provided on the inner surface of the lower support column 2. The outer diameter of the upper column 1 is often made smaller than the gap between the screw holes 22 and is loosely fitted to the lower column 2 to such an extent that no large rattling occurs. The insertion element 3 is formed with a screw thread 31 on the outer periphery of the base portion to form a threaded portion 31, and the columnar rod-shaped portion 32 and the tip portion are formed in a convex shape and provided with a protruding portion 33. The threaded portion 31 can be screwed into the thread of the through hole 6, and the diameter of the rod-shaped portion 32 is made smaller than the width of the recessed groove 4 so that it can be inserted into the recessed groove 4. The rod-shaped portion 32 is recessed. The diameter is larger than the diameter of the mounting hole 5 provided in the bottom 41 of the groove 4, and only the protrusion 33 can be inserted into the mounting hole 5. By inserting the protrusion 33 into the attachment hole 5, the inserter 3 is inserted into the attachment hole 5 and the through hole 6, and the upper support column 1 is attached to the lower support column 2.

  For example, as shown in FIG. 3, the insertion element 3 is not inserted into the attachment hole 5 in a state where the insertion element 3 is inserted into the through hole 6 with the projection 33 being detached from the attachment hole 5. Therefore, although the upper support column 1 is not fixed to the lower support column 2, the upper support column 1 is not attached to the lower support column 2 because the rod-shaped portion 32 is fitted in the recessed groove 4. The horizontal direction is not shifted in the direction of the arrow Y1 in the figure, and the concave groove 4 is continuous in the vertical direction. Will not hinder the movement. For example, when changing the mounting height of the upper column 1 fixed once, the insertion piece 3 is loosened so that the projection 33 is detached from the mounting hole 5 and the rod-shaped unit 32 is not pulled out of the groove 4, and the upper column 1 is By screwing the insertion element 3 so that the projection 33 is again inserted into the attachment hole 5 after being moved to a desired height, the hole positions of the attachment hole 5 and the through hole 6 are at least in the left-right direction. The insertion element 3 can be inserted without having to match at all, and the change in the mounting height of the upper support column 1 can be performed very simply. Further, when the upper support column 1 is newly attached to the lower support column 2, the upper support column 1 is inserted into the hollow portion 21 of the lower support column 2, the insertion element 3 is not inserted into the mounting hole 5, and the groove 4 It is possible to simply attach the protrusion 33 through the attachment hole 5 after the upper support column 1 is adjusted to a desired height in a state where the rod-like portion 32 is screwed to the extent that it is fitted.

  Although the material which forms the upper support | pillar 1 will not be specifically limited if it is a rod-shaped body in which the ditch | groove 4 and the attachment hole 5 can be formed, it can respond to the load from all directions derived from a user's weight etc. as a handrail. It is preferable to use a metal material such as steel, aluminum, stainless steel, titanium, zinc, etc. in order to be able to withstand, and further, an extruded profile that can form a complicated cross section such as a concave groove 4 continuously in the vertical direction. Is preferably used, and an extruded shape using aluminum or an alloy thereof can be suitably used as in the above-described embodiment. Moreover, it is not necessary to be hollow, and a solid or ribbed one can be used as necessary.

  The material for forming the lower support column 2 is preferably formed using the same metal material as that of the upper support column 1, but it is only necessary to form a hollow portion 21 in which the upper support column 1 can be freely inserted. If a complicated cross-sectional shape is not required, a general-purpose metal tube can be used.

  The inserter 3 is preferably a rod-like body provided with a threaded portion 31 that can be screwed into the through-hole 6 provided with a thread as in the above-described embodiment, but is not limited thereto, and is not limited thereto. Fastening means such as rivets, insertion pins, and the like can also be used. Moreover, in the above-mentioned embodiment, although the insertion element 3 is inserted only into one side wall of the upper column 1 and the lower column 2, the insertion element 3 may be inserted into the side walls on both sides as required for strength and the like. .

  FIG. 4 is an enlarged cross-sectional view of the vicinity of the mounting hole 5 in FIG. 2, but the insertion element 3 has a convex shape near the tip, so that a pressing portion 34 is provided around the protrusion 33, and the groove 4 A portion that comes into contact with the pressing portion 34 other than the attachment hole 5 of the bottom portion 41 is a receiving portion 42. When the inserter 3 is screwed in using the threaded portion 31 and the thread of the through hole 6, the inserter 3 is pushed in the direction of the arrow Y2 that is the direction opposite to the front side where the through hole 6 is provided. Then, the receiving portion 42 is similarly pushed in the direction of the arrow Y2 by the holding portion 34, so that the entire upper column 1 is pushed in the direction of the arrow Y2, and the outer surface of the upper column 1 is the inner surface of the lower column 2, that is, FIG. It is press-contacted to the screw hole 22 shown, and it is intended to improve the fixing strength of the upper support column 1 and prevent rattling.

  5A and 5B show details of the cap 7. FIG. 5A is a perspective view of the cap alone, and FIG. 5B and FIG. 5C are longitudinal sectional views showing the upper column attached to the cap 7. FIG. First, in (a), the cap 7 is formed by injection molding of a synthetic resin, and includes a hollow portion 73 into which the upper support column 1 can be inserted, a spacer portion 71 provided so as to surround the hollow portion 73, and a spacer portion 71. Spring portions 72 provided integrally at three locations, and a groove closing portion 74 provided integrally with the spacer portion 71 and closing the concave groove 4 portion. The upper half of the outer peripheral surface is a tapered surface 75. A stepped portion 76 for attachment to the lower column 2 is provided below the tapered surface 75.

  Next, (b) is a longitudinal sectional view showing a state before being attached to the lower support column 2 and the upper support column 1 being inserted. A stepped portion 76 is fitted and attached to the upper end portion of the lower support column 2, and the hollow portion 73 is substantially the same as the outer diameter of the upper support column 1, and the inner surface thereof serves as the spacer portion 71. A spring portion 72 bent inwardly is formed below the spacer portion 71 so as to protrude integrally. When the upper support column 1 is inserted into the hollow portion 73 of the cap 7 in the direction of the arrow Y3 downward from the lower end, the upper support column 1 is disposed inside the spacer portion 71 without any gap as shown in FIG. The space between the upper support column 1 and the upper support column 1 is closed by the spacer portion 71, but the spring portion 72 bent inward is also spread in the vertical direction. Here, the gap between the upper support column 1 and the lower support column 2 is blocked by the spacer portion 71, thereby suppressing the backlash of the upper support column 1. However, the spring portion 72 is further spread and expanded in the direction of the arrow Y4. The urging force acts on the upper column 1 and the rattle of the upper column 1 can be suppressed by this urging force. Even if the upper column 1 is loosely fitted to the lower column 2, the cap 7 rapidly If the gripping force is increased, the cap 7 can be temporarily stopped when positioning in the vertical direction. Furthermore, although the spring part 72 is bent inward, since it protrudes downward, it is difficult to prevent insertion of the upper column 1.

  Further, the spacer portion 71 has a tapered surface 75 whose upper side is inclined toward the outer surface of the upper column 1, so that the cap 7 interposed between the upper column 1 and the lower column 2 having different outer diameters is provided. The appearance is enhanced by relaxing the visual step due to the difference in outer diameter and creating a continuity.

  FIG. 6 is a longitudinal sectional view showing another example of the spring portion 72 in the cap 7, wherein (a) is before insertion of the upper column 1 and (b) is after insertion of the upper column 1. First, in (a), as in the previous embodiment, the spring portion 72 protrudes downward from the spacer portion 71 and is formed to be bent inward, but toward the outside near the lower end of the spring portion 72. An overhanging bulging portion 721 is provided. When the upper support column 7 is fitted to the cap 7, the bulging portion 721 is compressed between the outer surface of the upper support column 1 and the inner surface of the lower support column 2 as shown in FIG. The urging force can be increased.

  The material for forming the cap 7 is not particularly limited as long as it is a synthetic resin in which an urging force is generated by the provided spring portion 72, but a complicated shape is obtained by providing the spring portion 72 and the like integrally. Is preferably formed by injection molding, and thermoplastic synthetic resins such as polyethylene, polypropylene, ABS resin, AAS resin, and polyvinyl chloride resin, which are often used for injection molding, can be suitably used.

  FIG. 7 is an explanatory view showing an embodiment of the handrail device according to the present invention. A handrail post 10 is erected in the vicinity of the stairs T, a bracket 30 is attached to the attachment portion 101 of the handrail post 10, and a handrail member 20 is further attached to the bracket 30 to form a handrail device. The bracket 30 has a neck shape so that it is difficult for the hand M of the handrail user M to hit. A joint member 40 that can be bent in any direction is used at the bent portion of the handrail member 20. The handrail support column 10 is the handrail support column 10 according to the present invention as shown in the above-described embodiment. The inserter 3 is inserted into one side wall of the upper support column 1 and the lower support column 2 and attached. Since the groove 4 is directed to the side opposite to the side on which the user M walks, the user M does not see the groove 4 or the head of the insertion element 3 and the aesthetic appearance is enhanced. It has become a thing.

  Generally, the height from the ground surface to the upper surface of the handrail member 20 is about 650 to 900 mm, but by setting the range in which the concave groove 4 and the mounting hole 5 of the upper column 1 are provided according to the range. It can be possible to install in any installation situation. For example, two insertion elements 3 (through holes 6) are provided at intervals, and the attachment holes 5 are provided at equal intervals by equally dividing the intervals, thereby increasing the height of the attachment holes 5 at intervals. Adjustment is possible. Specifically, when the interval between the two insertion elements 3 (through holes 6) is 50 mm, if the interval between the mounting holes 5 is 50 mm, the height can be adjusted in increments of 50 mm. If the distance is 5 mm, the height can be adjusted in 12.5 mm increments. Further, when trying to correspond to the above range of 650 to 900 mm, the height of the handrail member 20 when the upper support column 1 is attached using the uppermost attachment hole 5 is set to 650 mm, and the uppermost attachment hole is provided. From 5 to the bottom mounting hole 5, by setting the length of 300 mm, which is a length obtained by adding the distance between the two insertion elements 3 (through holes 6) to the range where height adjustment is necessary, the mounting hole 5 can be up to 900 mm. The height can be easily adjusted in increments of. Moreover, since the positioning of the attachment hole 5 and the through-hole 6 is easy, a handrail device that can easily adjust the height of the handrail member 20 can be obtained.
