Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a handrail that is provided from a low place to a high place, for example, on an approach road or a mountain trail for improving safety and facilitating walking.

[0002]

[Prior art and its problems]

 For example, approach roads are often provided in places with height differences, and in many cases, slopes and stairs are continuously formed from a low place to a high place. Many of these approaches have handrails to improve safety and facilitate walking. On the other hand, since slopes and stairs are formed depending on the location, the slopes are usually different even between slopes and stairs. Some slopes and stairs have a gentle slope, while others have steep slopes. In addition, the handrail is generally composed of a large number of upright columns and a plurality of girders that are erected at different height positions between the columns. It is connected to a pillar.

By the way, since slopes and stairs are different in inclination, in the conventional handrail, connection specifications of girders and columns are made different according to the inclinations. However, in that case, the connection work was troublesome and the workability was poor, and the production cost was high because it was necessary to use parts that matched each specification. Further, since the uppermost girder slides its hand along the upper surface thereof, it is preferable that there is no protrusion on the upper surface. Therefore, the top girders on long slopes and stairs are usually supported from below by the seats on the upper ends of the pillars on the way. However, conventional handrails use seats made from different molds to match slopes and stairs. Therefore, the production cost was high.

[0004]

[Object of the Invention] The present invention provides a handrail that can easily perform the work of connecting the girder and the pillar, and thus the entire installation work, and can reduce the production cost even when installed on any sloping land. The purpose is to provide.

[0005]

[Means for achieving the purpose]

 The handrail of the present invention is a handrail that is provided from a low place to a high place on a sloping ground and has a large number of upright columns, and a plurality of girders that are erected at different height positions between the columns. The pillars consist of parent pillars and child pillars located between the parent pillars.The highest girder is directly installed between the adjacent pillars, and the other girders are the adjacent pillars. The girder is erected directly or through a pillar, and the end of the girder is connected to the pillar by the first connecting structure on the gently sloping ground, and the end on the steep sloping ground. The part is connected to the pillar by the second connection structure, and the uppermost girder installed between the parent pillars having the child pillars is supported from below by the seats provided at the upper ends of the child pillars. The first connection structure consists of a tubular bracket that is attached to the pole so that it opens laterally, and the girder The opening edge of the bracket is squeezed inward, and the second connection structure has a tubular bracket attached to the pillar so as to be opened in the lateral direction, and a bracket of the bracket. A spar girder inserted laterally into the opening is provided, and the spar end and splice girder are joined while maintaining the inclination of the girder by making at least one joint surface an inclined surface. The pedestal has an upwardly convex, substantially hemispherical pedestal that is fixed to the upper end of the child post, and a spherical lower surface that is in sliding contact with the spherical surface of the pedestal. The uppermost girder slides on the spherical surface of the pedestal so that the supporting member tilts along the inclination of the uppermost girder. It is characterized by being supported by a fixed seat.

[0006]

[Action]

 When adopting the first connection structure, it suffices to prepare a bracket that fits the highest girder and other girders, respectively, and it is not necessary to prepare a bracket that fits each angle of a gentle slope. In addition, all that is required is to fix the bracket to the column and insert the girder.

When adopting the second connection structure, a bracket or the like and a splicing girder suitable for the uppermost girder and other girders may be prepared. These members have a simple structure. Also, for example, when connecting the highest girder, the inclined joint surface is formed at the end of the girder and the inclined joint surface is formed at the end of the splicing girder, the bracket is fixed to the column, and the joint is connected. The work girder is attached, and the joint surface of the girder is brought into contact with the joint surface of the splicing girder to be bonded or welded. However, each of these operations is simple. The connection work to the columns of the other girders will be done in the same way as for the top girder.

Since the seat can change the inclination of the support member arbitrarily by sliding the support member on the spherical surface of the pedestal, it should be applied to any angled ground. You can Further, the work for arbitrarily changing the inclination of the support member is only to slide and fix the support member.

As shown in FIG. 3, the second connection structure 20 includes a tubular bracket 7b attached to the main pillar 2 so as to be opened in the lateral direction, and a splicing girder inserted in the opening of the bracket 7b from the lateral direction. 40, and a backing sleeve 50 for joining the end of the girder 4 and the splicing girder 40. The end of the girder 4 and the splicing girder 40 have their respective joint surfaces 4a, 40a. The inclined surface is formed by adhering and bonding while maintaining the inclination of the girder 4.

The bracket 7b has the same configuration as the bracket 7 used in the first connecting structure 10 except that the inner diameter is different. That is, the bracket 7b has such a size that the splicing girder 40 having the same diameter as the upper girder 4 can be inserted from the lateral direction.

FIG. 7 is a perspective view showing one step of manufacturing the second connection structure 20. The splicing girder 40 is a hollow body having the same diameter as the upper girder 4, and has a length that slightly projects when it is fitted into the bracket 7b. The joint surface 40a on the protruding side of the joint girder 40 is an inclined surface. The sleeve 50 includes a straight pipe portion 51 that is fitted inside the splicing girder 40 and an inclined pipe portion 52 that is slanted with respect to the straight pipe portion 51 and that fits inside the girder 4. , 52 are welded and joined.

When the upper girder 4 and the joint girder 40 are welded and joined together, the sleeve 50 may not be used.

In the handrail 1 provided on the stair A, the middle girder 5 and the lower girder 6 are also connected to the main pillar 2 by the second connection structure 20. However, the bracket 7c to be used has a tubular shape with a rectangular cross section, and has a size corresponding to the middle girder 5 and the lower girder 6. Further, the second connection structure 20 is similarly adopted in other steep slopes, that is, the stairs B and C. In addition, in the handrail 1 provided on the stairs B, the connection structure between the middle girder 5 and the lower girder 6 and the child pillar 3 is the same as that of the second connection structure 20.

In the handrail 1 provided on the slope A, the upper girder 4 is supported from below by a receiving seat 9 provided at the upper end of the child post 3 in the middle thereof. As shown in FIGS. 8 to 11, the pedestal 9 slides on a pedestal 91 having a substantially hemispherical shape which is fixed to the upper end of the child post 3 and which is convex upward, and slides on the spherical surface of the pedestal 91. And a support member 92 that is fixed in position. 8 is a side view of the seat 9, FIG. 9 is a view taken along the line IX of FIG. 8, FIG. 10 is a sectional view taken along line XX of FIG. 8, and FIG. 11 is a view taken along the line XI of FIG. The lower surface 92a of the support member 92 is a spherical surface that is in sliding contact with the spherical surface 91a of the pedestal 91. As shown in FIG. 12, the support member 92 is fixed to the pedestal 91 by bolts 93 at an arbitrary position on the spherical surface 91a as shown in FIG. The holes for the bolts 93 are formed only at one of the above arbitrary positions on the spherical surface 91a. Further, the support member 92 has a concave surface 92b for supporting the upper girder 4 from below. The upper girder 4 is supported by the receiving seat 9 in a state where the support member 92 is fixed by sliding on the spherical surface 91a of the pedestal 91 so that the concave surface 92b is inclined along the inclination of the upper girder 4. The upper girder 4 is fixed to the support member 92 by screws, for example. When the distance between the adjacent main pillars 2 is short, the child pillars 3 may not be provided like the stairs A. In such a case, naturally, the upper girder 4 is supported by the seat 9. There is no such thing.

As described above, in the handrail 1 of the present invention, the upper girder 4, the middle girder 5, and the lower girder are provided by the first connection structure 10 on a gently sloped ground such as slopes A, B, and C. 6 is connected to the main pillar 2 and the child pillar 3, and the upper girder 4, the middle girder 5 and the lower girder 6 are connected to the parent girder by the second connecting structure 20 in a steep sloping land such as stairs A, B and C.

When adopting the first connection structure 10, it is sufficient to prepare brackets 7, 7a, etc., which are suitable for the upper girder 4, the middle girder 5, and the lower girder 6, and are adapted to each angle of a gentle slope. You don't have to prepare anything. Therefore, the production cost is low. Further, the connecting work is easy because the brackets 7, 7a, etc. are fixed to the main pillar 2 and the child pillar 3, and the upper girder 4, the middle girder 5, and the lower girder 6 are inserted.

Further, when adopting the second connection structure 20, the brackets 7b, 7c, etc. and the splicing girder 40, which are suitable for the upper girder 4, the middle girder 5, and the lower girder 6, and the splicing girder 40, and a steep slope. The sleeve 50 suitable for each angle may be prepared. Since these members have a simple structure, the production cost is low. Further, for example, in the work of connecting the upper girder 4, the inclined joint surface 4a is formed at the end of the upper girder 4 and the inclined joint surface 40a is formed at the end of the splicing girder 40, and the bracket 7b is attached to the main pillar. 2, the splicing spar 40 and the sleeve 50 are attached, and the joint surface 4a of the upper spar 4 is brought into contact with the joint surface 40a of the splice spar 40 to be bonded or welded. Since it is simple, connecting work of the upper girder 4 is easy. It is easy to connect the middle girder 5 and the lower girder 6 to the main pillar 2 and the child pillar 3 as well as the upper girder 4.

Furthermore, in the seat 9 having the above-described structure, the inclination of the concave surface 92b can be arbitrarily changed by sliding the support member 92 on the spherical surface 91a of the pedestal 91. It can also be applied to slopes with various angles. That is, it is sufficient to prepare the seats 9 having the same structure formed of the same mold as the child posts 3. Therefore, the production cost is low. Further, the work for arbitrarily changing the inclination of the concave surface 92b is easy because the support member 92 is simply slid and fixed. Furthermore, the bolt 93 is provided at one place and is hidden by the upper girder 4 so that it cannot be seen. Therefore, a good effect can be achieved in terms of design.

As described above, in the handrail 1 of the present invention, the first connection structure 10, the second connection structure 20, and the receiving seat 9 can be easily manufactured and the production cost can be reduced. Since it is adopted, the whole installation work can be done easily and the production cost can be reduced.

The receiving seat 9 having the above-described structure can be used not only by arbitrarily changing the inclination of the concave surface 92b, but also by moving the upper girder 4 horizontally with respect to the post 3 as shown in FIG. It can also be used by shifting in the direction. That is, the support member 92 is fixed by the bolt 93 at a position laterally displaced from the top of the spherical surface 91a of the pedestal 91. By using the seat 9 in this way, the upper girder 4 can be positioned inward or outward relative to the subsidiary post 3.
