Definitions

  • This invention relates to a clamp used for the connection of steel pipes or the like for a temporary scaffold and a shelf or the like.
  • a clamp conventionally used in general is structured such that a holding body is pivotally mounted on one end of a body to be held, a base portion of a clamping bolt is pivotally mounted on the other end of the holding body, a U-shaped concave portion is formed on the other end of the body to be held, a tip end portion of the bolt is fitted in the concave portion, and a nut is screwed onto the bolt to be clamped together.
  • the clamps having the conventional structure involve the problems that since the concave groove is formed on the tip end of the body to be held, defects in section are produced to often bring about a lack of strength, and working becomes complicated and so on.
  • the present inventors have developed a clamp as disclosed in Japanese Utility Model Publication No. 57-18507.
  • the present invention provides a further improved clamp structured to pressedly tighten a body to be held with bolts without providing any bolt insertion hole and to be applicable to pipes having different dimensions.
  • pipes include a circular pipe in cross section and a square pipe in cross section, and the pipes respectively having two kinds of diameters are often used.
  • Various clamps are required in combinations of the pipes having the different diameters with the case of assembling the pipes orthogonally, parallel or diagonally to each other. The management of these various clamps increases in cost and becomes complicated.
  • the present invention is devised in order to solve the problems described above.
  • a clamp of the present invention is characterized in that a holding body 1 is pivotally mounted on one end of a body to be held 4, both base portions of a groove type auxiliary holding body 10 are pivotally mounted on the other end of the holding body 1, and a bolt 11 is screwed onto the tip end of the auxiliary holding body 10.
  • a spherical tip end portion of the bolt 11 is pressed and fitted to a spherically concave receiving portion A2 on the outside surface at the other end of the body to be held 7 in case of using a thick pipe, while being pressed and fitted to a spherically concave receiving portion A1 on the outside surface at the other end of the body to be held 4 in case of using a thin pipe, so that the pipe is uniformly pressed and held by the holding body 1, the body to be held 7 and a hinge portion of the auxiliary holding body 10.
  • a square hole 1a is bored in the holding body 1, and a circular hole 2a is bored in the holding body 2.
  • a main shaft 3 composed of a square column portion and a cylindrical portion is inserted into the square hole 1a and the circular hole 2a, and the main shaft 3 and the holding body 1 are rotated as one body by the square column portion of the main shaft 3, while the holding body 2 is released from the rotation of the main shaft 3 by the cylindrical portion of the main shaft 3.
  • the side of the square column portion of the main shaft 3 is fixedly attached to the holding body 1, and the other end of the main shaft 3 constitutes a rotary plate 3a.
  • a pin fit cover member 4 is pivotally mounted on the holding body 2 with a pin 5.
  • the pin fit cover member 4 is pushed up to release the holding body 1 and the holding body 2 from the rotation.
  • the pin fit cover member 4 is covered over the rotary plate 3a of the main shaft 3 to fix the holding body 1 and the holding body 2 for rotation.
  • Figs. 1, 2 and 4 show an embodiment in case of using a thick pipe
  • Figs. 3 and 5 show an embodiment in case of using a thin pipe, respectively.
  • a clamp of the present invention comprises a holding body 1 pivotally mounted on one end of a body to be held 7 with a pin 8. Both base portions of a groove-type auxiliary holding body 10 are pivotally mounted on the other end of the holding body 1 with a pin 9, and a caulking reinforcement member 12 is caulked to form an external thread at the tip end of the auxiliary holding body 10 or a nut 13 is fixedly attached to the tip end of the auxiliary holding body 10.
  • a bolt 11 having a spherical tip end is screwed onto the external thread.
  • the tip end of the auxiliary holding body 10 may be thickened so that an external thread is formed on the thickened portion and the bolt 11 is screwed onto the external thread without using the caulking reinforcement member 12 and the nut 13.
  • Spherically concave receiving portions A1 and A2 are formed on the outside surface at the other end of the body to be held.
  • pipes B1 and B2 are surrounded with the holding body 1 and the body to be held 7, and the tip end of the auxiliary holding body 10 is superimposed on the body to be held 7. Subsequently, the bolt 11 is rotated to pressedly fit the tip end of the bolt 11 to the concave receiving portion A1 or A2 on the outside surface at the other end of the body to be held.
  • Fig. 6 is a view showing the operation of a clamp which is made freely orthogonal. Hereinafter will be described the operation of the clamp which is made freely orthogonal with reference to Fig. 6.
  • a hole 2a is bored in the holding body 2 of the clamp, and a cylindrical portion 3b of the main shaft 3 is freely inserted into the hole 2a.
  • An octagonal rotary plate 3a is formed at the top of the main shaft.
  • the cylindrical portion 3b extending from the octagonal rotary plate 3a of the main shaft 3 is inserted into the hole 2a of the holding body 2.
  • a square column portion 3c extending from the cylindrical portion 3b of the main shaft 3 is inserted into a square hole bored in the holding body 1 and fixedly attached to the holding body 1, and the main shaft 3 is rotated together with the holding body 1.
  • a pin fit cover member 4 is pivotally mounted on the holding body 2 with a pin 5.
  • Fig. 1 shows an embodiment in case of using the circular pipe clamps combined with each other at right angles.
  • a caulking reinforcement member 6 is used for the main shaft.
  • Fig. 2 shows an embodiment in case of using the circular pipe clamps combined diagonally to each other.
  • the caulking reinforcement member is used for the main shaft.
  • Fig. 3 shows an embodiment of clamping a thin circular pipe.
  • Fig. 4 shows an embodiment in case of using the square pipe clamps combined orthogonally to each other.
  • Fig. 5 shows an embodiment in case of using the square pipe clamps combined diagonally to each other. In either of the embodiments shown in Figs. 4 and 5, any caulking reinforcement member 6 is not used.
  • Fig. 6 is a view showing the main shaft 3 having the square rotary plate 3a.
  • Fig. 8 shows a combination of the main shaft 3 having the circular rotary plate 3a formed with the square hole 3d and the pin fit cover member 4 having the square projection 4b fitted to the square hole 3d.
  • Fig. 9 shows a combination of the main shaft 3 having the circular rotary plate 3a formed with a cross groove 3e and the pin fit cover member 4 having the projection 4e fitted to the cross groove.
  • Fig. 10 is a view showing the caulking reinforcement washer.
  • the clamp of the present invention is provided with the auxiliary holding body, and the bolt is screwed onto the tip end of the auxiliary holding body to pressedly fit the spherical tip end of the bolt to the spherically concave receiving portion on the outside surface at the other end of the holding body.
  • the bolt is screwed onto the tip end of the auxiliary holding body to pressedly fit the spherical tip end of the bolt to the spherically concave receiving portion on the outside surface at the other end of the holding body.
  • the clamp of the present invention is free from any defect in cross section, and there is no fear of breakage when used. Further, since the tip end of the bolt and the concave receiving portion of the body to be held are brought into contact with each other on their spherical surfaces, there is no problem in rotating and tightening the bolts.
  • the clamp can be applied to pipes having different diameters with safety and security.
