Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a joint for connecting handrails used in stairs or the like, and can be used at any angle.

[0002]

[Prior art]

 Conventionally, when installing handrails on indoor or outdoor stairs, it is ideal that the handrails should be connected along the wall surface so that there is no break in the middle and the body can be supported at any part. ing.

[0003]

[Problems to be solved by the device]

 By the way, the stairs are curved as necessary like a staircase that rotates 180 °, and a landing is provided, and the direction of the handrail and the slope change. Generally, a straight handrail is used, and the handrail must be cut and processed at the site according to the direction and the angle of the gradient, which requires skill. There was a problem saying. In order to solve the problem, joints that are made to match any angle are used, but several kinds of joints have to be used to form one stair, which results in high cost. was there. The present invention has been made in view of these problems, and an object thereof is to provide a handrail joint that is easy to construct and can be adjusted to any direction and angle of inclination.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a hemisphere obtained by dividing a hollow sphere into halves, and a cylindrical body having a radius smaller than the radius of the hemisphere, and a center line of the dividing surface of the hemisphere. , A pair of joint members formed so as to project in the same direction as the split surface and in contact with the split surface of the hemisphere, and projecting a convex body for connecting to the center of the hemisphere. , A fitting convex portion is formed on one side and a fitting step portion is formed on the other side so as to fit the divided surfaces of the hemisphere of the joint member to each other. The hemispheres are rotatably connected around a protruding projection for connection, and the portions of the cylindrical body projectingly formed on the hemisphere that are not connected to the hemisphere are diagonally cut so as to cover each other. It is characterized by being removed.

[0005]

[Action]

 According to the handrail joint, since the pair of joint members are rotatably connected to each other around the convex body, the handrail joint can be used as a joint for a handrail corner or the like according to an arbitrary direction or an angle of inclination. Further, by forming the fitting convex portion and the fitting step portion on the divided surface of the hemisphere, the divided surface can be formed without a gap, and further, the inclined surface portion 7 provided on the tubular body 5 allows the joint material 1 to be formed. Since the rotation angle of the hemisphere 4 can be rotated at a right angle or more, and the hemisphere 4 is covered on one side, the gap between the hemisphere 4 and the cylinder 5 can be minimized.

【Example】

 Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view of a joint 1 of the present invention. The joint 1 is composed of a pair of joint members as shown in FIGS. 2, 3, 4 and 5, 6, 7.

As shown in FIGS. 2, 3 and 4, one joint member 2 is an integrally molded product made of synthetic resin, and includes a hemisphere 4 obtained by dividing a hollow sphere into halves. A cylindrical body 5 having a radius smaller than the radius of the center of the dividing surface of the hemisphere 4 and in the same plane direction as the dividing surface and in contact with the dividing surface of the hemisphere 4. Become. At this time, a plane portion is provided so that the height direction of the hemisphere 4 is deleted by the radius of the cylinder 5 so that the hemisphere 4 and the cylinder 5 do not have a step. Then, a convex body 6 for coupling is projected at the center of the hemisphere 4, and a portion of the cylindrical body 5 projectingly formed on the hemisphere 4 that is not coupled to the hemisphere 4 is a hemisphere from the side where the cylinder 5 contacts. It is formed so as to be obliquely cut away on the opposite side of 4 to form the inclined surface portion 7. A fitting convex portion 8 is provided around the divided surface of the hollow hemisphere 4, and a screw hole 10 having a thread groove is formed at the center of the convex body 6.

The other joint member 3 is an integrally molded product made of synthetic resin as shown in FIGS. 5, 6 and 7, and like the one joint member 2, a hollow sphere is divided into halves. A cylindrical body 5 having a radius smaller than the radius of the hemisphere 4 is attached to the formed hemisphere 4 in the same plane direction as the division plane of the hemisphere 4 as a central axis and in the direction of the division of the hemisphere 4. The protrusion is formed so as to contact the split surface. At this time, a plane portion is provided so that the height direction of the hemisphere 4 is deleted by the radius of the cylinder 5 so that the hemisphere 4 and the cylinder 5 do not have a step. Then, a convex body 6 for coupling is projected at the center of the hemisphere 4, and a portion of the cylindrical body 5 projectingly formed on the hemisphere 4 that is not coupled to the hemisphere 4 is connected to the hemisphere 4 from the side where the cylinder 5 contacts. It is formed so as to be obliquely cut away on the opposite side to the inclined surface portion 7. Then, a fitting step portion 9 is formed around the divided surface of the hollow hemisphere 4, and a through hole 11 for inserting a screw 12 is formed at the center of the convex body 6.

The pair of joint members 2 and the hemispheres 4 of the joint member 3 are fitted to each other, the screw 12 is inserted into the through hole 10 of the joint member 3, and screwed into the screw hole 9 of the joint member 2 for connection. . As a result, the joint member 2 and the joint member 3 are rotatably connected about the convex body 6. (See FIGS. 8 and 9)

In such a joint 1, since the fitting convex portion 8 and the fitting step portion 9 are fitted to connect the hemisphere 4, the hemisphere 4 is less likely to be displaced and can be firmly connected. Further, the angle of rotation of the joint material 1 can be rotated at a right angle or at a right angle or more by the inclined surface portion 7 provided on the tubular body 5, and the hemispherical body 4 and the tubular body 5 are connected to each other because the hemispherical body 4 is covered. The gap between them can be minimized.

Then, as shown in FIG. 10, the joint 1 is inserted with the handrail 13 into each of the tubular bodies 5 of the joint member 2 and the joint member 3, and the handrail 13 is rotated in accordance with the direction and the angle of the gradient to adjust the angle. After the determination, a screw is screwed onto the handrail from the portion of the joint 1 which is the lower surface of the tubular body 5 to fix the handrail. At this time, the side where the hemisphere 4 of the joint 1 projects is used as the inside. When used in this direction, there is no large unevenness on the upper surface side, and it is possible to make the structure comfortable to the touch.

[Effect of the invention]

 As described above, according to the handrail joint of the present invention, since the pair of joint members are rotatably connected to each other around the convex body, the handrail can be adjusted to an arbitrary direction or an angle of inclination. Can be used in the corner of. Therefore, it is not necessary to cut the handrails according to the direction and the angle of the slope as in the past, and joints made to match any angle can be freely adjusted with this joint. Because it is done, it is not necessary. Therefore, it is possible to easily construct a handrail that does not break at any part. By making the radius of the hemisphere different from that of the cylinder, the handrail can be accented rather than connected by the same shape, and a handrail with a better appearance can be configured.
