[Technical field to which the invention belongs]

 The present invention relates to a universal joint for connecting cross members constituting a fence-like structure and a fence-like structure using the joint. More specifically, the end portion of the cross member to be joined is obliquely cut and melted. A universal joint for horizontal members that allows the left and right horizontal members to be easily and freely set and arranged at the desired connection angle without touching each other, and using such a universal joint, the corners will look great at the required angle. It concerns well-structured fence-like structures.

[0002]

[Prior art]

 Fence-like structures are widely used as handrails, fences, balustrades, fences, blinds, etc.The structure is a plurality of pillars erected at a predetermined interval and a horizontal bridge installed between these pillars. It is generally made of wood.

By the way, as a cross member of such a fence-like structure, a long straight rod is used, and this straight rod is sequentially connected to an adjacent straight rod through a support column. As a result, a long fence-like structure covering a wide area will be constructed. Since this long fence-like structure is used as handrails for stairs and fences surrounding no-entry areas, it is not possible to construct handrails or fences with corners by simply connecting straight horizontal members in a straight line. Normally, a fence-like structure having a desired corner angle is obtained by changing the angle at which the right and left linear cross members are connected to the pillar located at the corner.

However, if there is no pillar located at the corner of the fence-like structure, the left and right linear cross members must be directly connected to each other at the corner. In this direct connection of cross members, the ends of the straight cross members are cut diagonally so as to match the corner angle of the fence-like structure, and then the ends are welded together (so-called "fastening"). ) Are often connected.

Therefore, the laborious and laborious work of diagonal cutting and welding is required, which significantly deteriorates the work efficiency, and the appearance of the weld at the corner is not good. Further, if there is a deviation in the diagonal cutting angle of the cross member or a deviation in the welding angle between the cross members, even if the angle deviation is slight at the connection site, the end of the cross member on the side facing the connection is connected. The deviation is amplified in the part, and the degree of this amplified deviation becomes more remarkable as the crosspiece becomes longer, so that the other end of the welded crosspiece is accurately connected to the adjacent crosspiece or column. There was a drawback that I could not.

Further, even if there is a pillar located at the corner of the fence-like structure, it is possible to cut the end portion of the straight cross member diagonally so as to fit the corner angle and then connect it to the pillar. Due to the large number of defects, the same drawbacks as described above cannot be avoided.

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned drawbacks of the conventional corner connection structure in the fence-like structure, and diagonally cuts and welds the ends of the cross members to be connected. It is an object of the present invention to provide a horizontal member universal joint in which the left and right horizontal members can be easily and freely set and arranged at a desired connection angle.

Another object of the present invention is to provide a fence-like structure in which a corner is formed at a desired angle using a universal joint as described above so that it looks good.

The block piece 1 has a substantially columnar shape, and a circular shaft hole 11 having a sunk hole penetrates through the substantially cylinder body, and a bolt described later is inserted into the shaft hole 11. . As shown in FIGS. 1 and 2, the block piece 1 is provided with a substantially spherical sliding convex surface 12 and a sliding concave surface 13, and the sliding convex surface 12 of one block piece 1 to be paired is formed. The other block piece 1 is fitted in the sliding concave surface 13 in a sliding state so that the joint can move. The shapes of the sliding convex surface 12 and the sliding concave surface 13 may be formed in any uneven surface as long as they can be fitted to each other and can be slid. Further, one end of the substantially cylindrical block piece 1 is formed on a flat surface which is perpendicular to the peripheral surface of the cylinder, and two locking claws 15 and 15 are projectingly provided on the vertical end surface 14. The block piece 1 and the cross member B are connected by the locking claws 15. Further, a U-shaped groove portion 16 is formed in the block piece 1, and an edge of a panel described later can be fitted into the groove portion 16.

What is indicated by reference numeral 2 is a fastening member for hinge-connecting the pair of block pieces 1 and 1. The fastening member 2 comprises a stainless steel bolt 21 and a nut 22. The bolts 21 are inserted into the shaft holes 11 of the block pieces 1.1, respectively, and the nuts 22 are screwed into the tips of the bolts 21 to connect them by hinges.・ A universal joint consisting of 1 can be obtained. At the time of this connection, both block pieces 1 and 1 are rocked around the bolt 21 to set a desired connection angle, and then the nut 22 is tightly connected to the bolt 21 so that the block pieces 1 are connected to each other. Fasten. When it is necessary to fix the pair of block pieces 1 and 1 more securely after the bolts 21 and the nuts 22 are fastened in this way, screw 23 from the vertical end surface 14 of the block piece 1 as shown in FIG. It can also be screwed in to increase the fastening force. Further, it is possible to cover the bolts 21 and the nuts 22 with caps 24, 24 from the outside to improve the appearance.

Here, by using the universal joint composed of the pair of block pieces 1.1 as described above, the left and right cross members B and B are connected at a desired angle, and the fence-shaped structure (in the present embodiment, A method of forming the handrail of the stairs K will be briefly described.

First, two block pieces 1, 1 made of cast products of the same shape are prepared, and the sliding convex surface 12 of one block piece 1 is made to match the sliding concave surface 13 of the other block piece 1 and assembled. In such a state, the angle formed by both block pieces 1 and 1 is adjusted so as to approximately match the corner of the fence-like structure to be constructed. Next, the bolt 21 is inserted into the shaft holes 11 of the pair of block pieces 1.1 whose angles have been adjusted, and the nut 22 is screwed into the tip of the bolt 21 so that the block pieces 1 are aligned with each other in the angular position. Temporarily tighten with. Then, as shown in FIG. 4, the locking claws 15, 15 of each temporarily tightened block piece 1 are inserted into a substantially semi-cylindrical lower transverse member Bd, and the insertion position is connected from the outer surface of the lower transverse member Bd. A member J (a screw in this embodiment) is screwed and fixed to the locking claw 15. Next, fine-tune the angle formed by the pair of block pieces 1.1 again to set it so that it fits exactly at the corner of the fence-like structure, and then tighten the nut 22 to the bolt 21 to tighten the block pieces 1.1. Securely fasten each other. In this case, as shown in FIG. 1, by screwing the screw 23 from the vertical end surface 14 of the block piece 1 as necessary, the pair of block pieces 1 and 1 can be fixed more firmly. Wear. Then, when a substantially semi-cylindrical upper cross member Bu is fitted onto the lower cross member Bd fixed to the vertical end face 14 of each block piece 1 from above, the cross member consisting of the upper cross member Bu and the lower cross member Bd. B (aluminum metal material in this embodiment) is connected to the vertical end surface 14 of each block piece 1. After connecting the left and right cross members B and B to the universal joint composed of a pair of block pieces 1.1 at a desired angle, the groove parts g of each lower cross member Bd and the groove parts 16 of each block piece 1 are connected to each other. When the edge of the panel P (glass plate in this embodiment) is fitted into the groove of each panel frame Pf attached to the pillar S, a fence-like structure having corners as shown in FIG. 5 is obtained. . Since the end portion e of the horizontal member B of the present embodiment is connected to the vertical end surface 14 of the block piece 1, it is only necessary to cut the end portion e at a right angle, and the processing of the horizontal member B at the work site is possible. Easy to work.

In the horizontal member connecting mechanism using the universal joint composed of the pair of block pieces 1.1 as described above, as shown in FIG. 6, the angle formed by the left and right horizontal members B, B is The range is up to 45 degrees in the vertical direction with respect to the axial direction of the cross member B, and it is possible to construct a fence-like structure having a desired corner by freely setting the connection angle in this range. The range of the upper and lower limits of the connecting angle can be naturally changed by devising the shape of each block piece 1 as necessary.

In this way, by adopting the universal joint whose angle can be adjusted to connect the horizontal members at the corners of the fence-like structure, the left and right horizontal members can be connected without cutting the ends of the horizontal members diagonally and welding them. The connection angle can be set easily and freely to the desired connection angle, which greatly improves the work efficiency at the assembly work site of the fence-like structure and also causes poor-looking welding beads at the connection part. Instead, a pair of block pieces 1 and 1 are symmetrically arranged to obtain a corner with an excellent appearance. Moreover, in the universal joint of the present embodiment, the two block pieces 1.1 made of cast products of the same shape are paired, so that the two cast products required to form the universal joint are It can be obtained with various types of molds, and the manufacturing cost required for molds can be reduced. Therefore, it becomes possible to reduce the construction cost and shorten the construction period.

It is also possible to construct a lattice type fence-like structure as shown in FIG. 7 by using the universal joint composed of the block pieces 1.1 of the first embodiment. In this lattice type fence-like structure, a plurality of ballasters V, V, ... Are attached at a predetermined interval between a pair of upper and lower horizontal members B, B '. Since the groove portion 16 of each block piece 1 is covered with the U-shaped cap C as shown in FIG. 8, even if the grooved block piece 1 is applied to the lattice type, a good-looking corner can be obtained. As the horizontal member B, as shown in FIG. 9, a substantially cylindrical body in which a lower horizontal member Bd having no groove portion and an upper horizontal member Bu are fitted is used.

Next, a universal joint according to a second embodiment of the present invention will be described with reference to FIG. The second embodiment is different from the first embodiment in that the shape of the block piece 1 is changed. The shape of the block piece 1 of the second embodiment is a substantially prismatic body, and a sliding convex surface 12 and a sliding concave surface 13 are formed on this prismatic body. As with the first embodiment, one block to be a pair is formed. The sliding convex surface 12 of the piece 1 is fitted in the sliding concave surface 13 of the other block piece 1 in the sliding state to enable the joint operation. Then, one end of the block piece 1 is formed on a flat surface perpendicular to the peripheral surface of the prism, and one locking claw 15 is projectingly provided on the vertical end surface 14, and the locking claw 15 is The block piece 1 and the horizontal member B are connected together. The shape of the horizontal member B 1 is a substantially rectangular tubular body in which a lower horizontal member Bd and an upper horizontal member Bu are fitted together, and is adapted to the shape of a substantially rectangular columnar member of a universal joint composed of a pair of block pieces 1 1. By adopting a pair of block pieces 1.1 having different shapes in this way, it is possible to obtain a fence-like structure having corners with a wide variety of appearances.

The embodiment of the present invention is generally as described above, but the present invention is not limited to the above-described embodiment, and various modifications are made within the scope of the “claim for utility model registration”. Is possible. For example, in addition to adjusting the angle of the pair of block pieces 1.1 of the present embodiment in the vertical plane of the handrail of the stairs K as shown in FIGS. 5 and 7, the landing L of the stairs K as shown in FIG. It is also possible to apply the universal joint of the present embodiment to the corner of the handrail in, and at the corner of the handrail of this landing L, rotate the universal joint consisting of a pair of block pieces 1.1 by 90 degrees around the axis. By adjusting the angle in the horizontal plane in this state, the left and right cross members B and B are set to the required connection angle and arranged. In this case, the block piece 1 and the cross member B can be reliably connected by changing the shape and position of the locking claw 15 provided at the end of the block piece 1. It goes without saying that such changes also belong to the technical scope of the present invention.
