Consequently, the walker can walk stably in both walkings. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a beam handrail that is installed and used in an entrance or hallway of a house or public facility, a park, or the like.

  As this kind of beam handrail, for example, a bracket made of cast aluminum and having a front V-shape is fixed to the upper end of an aluminum extruded column and an aluminum extruded beam is also installed via the bracket. At this time, the beam is formed into a pipe having a circular cross section, and is used as a partition with an exhibit in a front door, a park, a museum, or the like.

Design Registration No. 940360

  In this case, a beam handrail that is simple in design and smart and matches the landscape can be used. However, the beam handrail is not necessarily suitable for pedestrians such as elderly people, sick people, and disabled people to walk and communicate. That's not true. In other words, support walking is a pedestrian holding the beam and walking with the body load applied to the beam with a grip hand, and telling walking is also a pedestrian holding the beam and walking with a hand guided by the beam. However, since the beam forms a pipe having a circular cross section, it is difficult to grasp itself, and in the case of walking on a support, the gripping hand rotates in the depth direction of the beam, that is, on the side opposite to the pedestrian. It is easy to perform, and there is a possibility that the stable hand grip and the stable walking by this will be obstructed, and also in the case of walking, the grip hand rotates in the forward direction and the depth direction of the beam due to the swing of the body due to walking. For example, the body cannot be supported when there is a whisper, for example, and there is a possibility that a stable hand grip and a stable walking may be hindered.

  Furthermore, since the bracket having the front V-shape is generally fixed with a horizontal fixing piece attached to the lower surface of the beam and a screw from the lower surface, the pedestrian who walks and supports the above-mentioned walking is placed near the column. When it arrives, the gripping hand touches the fixed piece, especially the step at its tip, which makes it uncomfortable, and it also causes the sense of discomfort to stop walking, leaving the possibility of hindering smooth walking.

  The present invention has been made in view of such circumstances, and the problem to be solved is to ensure a stable hand grip and a stable walking while maintaining a good design, especially supporting walking and walking. Is to provide a beam handrail.

  In accordance with the above-mentioned problems, the present invention makes the cross-sectional shape of the beam an elliptical shape suitable for a hand grip, in particular, a grip shape having a substantially oval cross-section, and the tip end side of the beam is directed toward the pedestrian with respect to the column. By placing the beam so as to be inclined upward, the upper surface of the beam is inclined upward toward the pedestrian side, and a wide curved surface that is wide in the depth direction makes it possible to easily grasp the beam and adapt to the hand. In addition, when walking on a pedestrian, the wide curved surface that slopes upward supports the body's load, reliably preventing the gripper from turning in the depth direction, and reducing the load on the pedestrian's hand. On the other hand, in the same way, the possibility of rotation of the gripping hand due to the swinging of the body is prevented, and the body is supported against whispering. With a handful In other words, the invention according to claim 1 is formed by forming a beam having a grip shape with a substantially egg-shaped cross section and pointing the tip end of the beam upward toward the pedestrian. It is a beam handrail characterized by being inclined and arranged on a support via a bracket.

  In addition to the above, the invention according to claim 2 ensures a high degree of walking stability by making the beam having a substantially oval cross section suitable for securing the grip of the hand. The beam handrail according to claim 1, wherein the beam has a long axis of 4 to 6 cm and a short axis of 3 to 5 cm. is there.

  In addition to the above, the invention described in claim 3 ensures a high level of walking stability by providing an inclination angle suitable for ensuring the stability of the hand grip of the beam having the substantially oval cross section. The beam handrail according to claim 1 or 2, characterized in that the upward inclination of the beam is an angle of 30 to 40 °.

  In addition to the above, the invention according to claim 4 is also configured to eliminate a sense of incongruity of the pedestrian in the vicinity of the support pole during supportive walking and telling walking so that smooth and stable walking can be achieved. 2. The bracket according to claim 1, wherein the bracket has a substantially V-shape in front which forms a curved slope toward the column with a width substantially the same as that of the beam, and tips on both sides thereof are arranged steplessly on the lower surface of the beam. The beam handrail described in 2 or 3 is used.

  The present invention uses each of these as the gist of the invention as means for solving the above problems.

  Since the present invention is configured as described above, the invention according to claim 1 is configured such that the cross-sectional shape of the beam is an elliptical shape suitable for a hand grip, in particular, a grip shape having a substantially egg-shaped cross section. By arranging the tip end of the beam to be inclined upward toward the pedestrian, the upper surface of the beam is inclined upward toward the pedestrian side and a wide curved surface extending in the depth direction makes it easy to grip and The beam that fits in the hand can be gripped, and the wide curved surface that is inclined upward supports the body load when walking and supporting the pedestrian, and reliably prevents the gripper from rotating in the depth direction. While reducing the load burden on the hand of the pedestrian, while preventing the possibility of rotation of the gripping hand due to the swinging of the body during transmission, the body is supported against whispering and the like. Walking, Stable and hand grip was possible a stable walking and the beam handrail of example walk of the pedestrian can be provided.

  In addition to the above, the invention according to claim 2 can secure a high degree of walking stability by making the dimensions suitable for securing the hand grip of the beam having a substantially oval cross section. It can be.

  In addition to the above, the invention described in claim 3 ensures a high level of walking stability by providing an inclination angle suitable for ensuring the stability of the hand grip of the beam having the substantially oval cross section. Can be obtained.

  In addition to the above, the invention described in claim 4 can also provide a smooth and stable walking by eliminating a sense of incongruity of the pedestrian in the vicinity of the support pole during support walking and telling walking.

  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. In the figure, A is a beam handrail made of aluminum by using, for example, an aluminum extruded material and an aluminum casting. A beam 2 having a grip shape of a mold is formed, and the tip of the thick end of the beam 2 is inclined upward toward the pedestrian and is disposed on the support column 1 via the bracket 3. The upper end of the column 1 is installed by installing the upper beam 2 via the bracket 3 fixed to the upper end of the column 1 and installing the intermediate beam 2 via the bracket 3 at the tip of the intermediate take-out arm 12. For example, the beam 2 is arranged on the upper and lower two stages in the middle for a wheelchair.

  The beam 2 is formed by using a single or a plurality of aluminum extrudates and is formed in the above-mentioned substantially oval shape, and in this example, the beam 2 is a long length fixed to the bracket 3. The cross-sectional substantially oval shape is obtained by combining a base material 21 and a plurality of, for example, two types of extruded materials, which are fitted and fixed to the long base material 21, for example, two types of extruded materials. I'm trying to make it. The long base material 21 has a curved surface that is a fraction of the outer circumference of the substantially oval cross section, and the long beam material 22 is extruded so as to form the remaining curved surface. A fitting convex portion is arranged on the upper surface of the material 21 and a fitting concave portion is arranged on the lower surface of the long beam member 22, respectively. , By screwing from the fitting convex portion into the fitting concave portion of the long beam material 22 so as not to protrude from the lower surface of the long base material 21, they are fixed at a predetermined interval and integrated into a long length. It is a scale beam 2. At this time, the beam 2 is anti-stained by applying anti-slip treatment by roughening the surface as necessary, or forming a resin coating layer 23 or applying a coating or paint as shown in the figure. Properties, heat insulation, and anti-slip properties due to friction can be obtained.

  At this time, the beam 2 has a common cross-sectional shape having the same dimensions at both the upper and lower two stages, the major axis of the section is 4 to 6 cm, and the minor axis of the section is 3 to 5 cm. The major axis of the cross section of the beam 2 is, for example, about 4.6 cm, and the minor axis of the section is about 3.9 cm. As a result, for example, as a standard handgrip size that fits an adult's hand when squeezing the hand gently, it is possible to obtain a favorable familiarity of the hand that does not give the pedestrian a sense of incongruity and the stability of walking. It is.

  The length of the long axis of the beam 2 is preferably 4.5 to 6 cm when the beam 2 is installed at a standard height, and the length of the short axis is preferably 3.5 to 5 cm. Below these lower limits, the beam 2 becomes thin, and when it exceeds the upper limit, the beam 2 becomes thicker. In either case, the hand that holds the beam 2 has a sense of incongruity, and the stability of walking is impaired. In particular, it is preferable that the long axis is 4.5 ± 0.3 cm and the short axis is 4 ± 0.3 cm in order to ensure a stable hand grip and walking stability when performing walking and walking. .

  The beam 2 formed in this manner is supported by the bracket 3 so that the tip of the thick end in the substantially oval cross-sectional shape is inclined upward toward the pedestrian. In this case, the upward inclination angle is 30 to 40 °, and in this example, particularly, this is 33 °, so that a broad curved surface having a substantially egg-shaped cross section is formed on the upper surface of the beam 2. And the upward inclination of the pedestrian is easily adapted to the angle of the pedestrian's hand with respect to the beam 2 so that the pedestrian can easily grasp it. The upward tilt angle of the beam 2 is preferably 30 to 40 ° when the beam is set at a standard height, and is below the lower limit, and above the upper limit, the allowable range of the hand angle with respect to the beam This makes it difficult to grasp and become unfamiliar with hand grips. In order to obtain ease of gripping and familiar hand of a hand by a pedestrian, it is preferable to set the upward inclination angle to 35 ± 3 °.

  On the other hand, the bracket 3 is formed to have a substantially V-shaped front surface having a curved surface sloped toward the support column with substantially the same width as that of the beam 2, and the tip thereof is arranged steplessly on the lower surface of the beam 2. The bracket 3 is provided with a base 31 standing upwards substantially the same width as the beam 2 and overhangs on both sides of the base 31, and in this example, the thickness of the end in the overhang direction is the thickness of the long base material 21. And a fixed piece 32 substantially equivalent to the above, and the bottom surface of the fixed piece 32 is made of an aluminum casting cast into the above-mentioned front V shape as a curved slope that gently curves from the base portion 31, The bracket 3 is configured to support and support the beam 2 by using a common one at the upper end and the middle of the column 1.

  In this example, the bracket 3 is fixed upward at the upper end of the support column 1 with its lower end fixed to a bracket receiver 11 that is erected at the tip of the support column 1, and fixed to the support column 1 in the middle of the support column 1. The lower end of the take-out arm 12 that is inclined or bent upward is fixed in the same manner. At this time, the bracket receiver 11 and the take-out arm 12 and the bracket 3 in this example are fixed to about 1/2 width. This is done by contacting the front and back with bolts and nuts so that the rotation protrusions of the bolts are hinges, and covering the front and rear surfaces with caps to prevent the bolts and nuts from being exposed and to rotate them on slopes including flat ground and stairs. The angle of the bracket 3 can be adjusted by appropriately rotating the moving projection.

  The support for supporting the beam 2 by the bracket 3 is fixed by embedding the fixing piece 32 of the bracket 3 in the beam 2 and screwing from the fixing piece 32. When the beam 2 is formed, the long base material 21 is lacking by the length of the bracket 3 at the position where the support column 1 of the beam 2 is arranged, so that the bracket 3 is attached to the lacking part of the long base material 21. It is assumed that the long beam member 22 is directly fitted into the long beam member 22, for example, screwed into the fitting recess on the lower surface thereof, and the lower support is fixed. The lack of the long base material 21 is the length obtained by cutting the long base material 21 in advance for each beam 2 in the present example, and the long base material 22 has a long base material so that the position of the column 1 is opened. This is done by fixing 21.

  The beam handrail A formed as described above can be installed and used at a predetermined position in accordance with the angle of the ground surface on a flat ground or an inclined ground by making the angle of the bracket 3 adjustable. A is an elliptical shape suitable for gripping the cross section of the beam 2, particularly a generally oval cross section, while the tip end of the beam 2 faces upward toward the pedestal toward the pedestrian. By placing it so as to be inclined, the upper surface of the beam 2 is inclined upward toward the pedestrian side, and a wide curved surface is formed in the depth direction, thereby enabling a hand grip of the beam 2 familiar to the hand. When a pedestrian grips the beam 2 and walks while holding the body load on the beam 2 with a hand grip, the upwardly inclined wide curved surface supports the body load and rotates in the depth direction of the hand grip. While reliably preventing performance, the load on the pedestrian's hand is reduced, while the pedestrian holds the beam 2 and walks with the hand guided by the beam 2 as well. To prevent the possibility of rotation of the gripping hand due to movement, and to support the body against whispering, etc., enabling the stable handholding and stable walking of these pedestrians who support and walk In particular, the length of the major axis and minor axis of the beam 2 and the angle of the upward inclination are suitable for supporting walking and walking, so that the stability of hand grip and walking is further secured. Can do.

  The example shown in the figure is as described above. However, it is assumed that the beam handrail has a single beam placed on the upper end of the column, the arrangement of the intermediate beam is omitted, and the beam is pushed by a single aluminum extrusion. Extrusion molding with a material, stepless arrangement on the lower surface of the beam of the bracket is performed by making the end of the fixing piece of the bracket as thin as possible, and the above-mentioned embedded fixing is performed on the beam or its Specific shapes and structures of beam handrails, beams, brackets, take-out arms used as necessary, etc. in carrying out the present invention, including performing by performing partial notch processing on long members, etc. The material, the relationship between these, the addition to these, and the like can be in various forms as long as they do not contradict the gist of the invention.
