Abstract

PURPOSE: To simply, quickly and safely facilitate installation by letting a joint section be composed of a fixed section, an insertion body and a cylindrical section, forming a thick wall pressing section with a plurality of slits formed within the cylindrical section, and forming the thick wall pressing section into a projected shape having a gentle curved projection surface in the inner wall direction of the cylindrical section. CONSTITUTION: A cylindrical section 4 is formed integrally with a fixed section 3, and engaged with an insertion body 2 inserted in from a cylinder inlet 6. Two thick wall pressing sections 7 are normally formed on the inner wall of the cylindrical section 4, and the thick wall pressing sections 7 are formed among a plurality of slits bored in the wall surface of the cylindrical section 4. Each thick wall pressing section 7 is projected to the inner wall side of the cylindrical section 4, and the projected section 7a is in a gentle projection shape. The insertion body 2 is fixed to the torso 11 of a mannequin and the like. For example, speaking of a fixing area for an arm section 10, the arm section 10 is inserted into the cylindrical section 4 in such a manner as to be fixed onto the torso section 11. In this case, since the thick wall pressing section 7 is pressed from the inner side by the insertion body 2, the thick wall pressing section 7 is thereby swelled outward, the insertion body 2 is thereby pressed against the inner wall of the cylindrical body 4. Since the inner wall surfaces of them are mutually pressed, the insertion body will never come out.

Are formed at right angles to the cylinder direction. In a state where the joint portion 1 is attached to the body portion 11 or the like, the cylinder inlet 6 side of the fixed portion 3 becomes the front surface side, and the cylindrical portion 4 integrally formed with the fixed portion 3 projects in the back side direction, that is, the inside direction of the body portion 11. ing.

The planar shape of the fixing portion 3 is a knot-shaped substantially triangular shape in this embodiment, but may be a circular shape, a quadrangular shape, or a polygonal shape more than that depending on the shape and size of the mounting body. A plurality of screw holes 5 are provided in the fixing portion 3 and fixed to the body portion 11 with screws 5a. The number of the screw holes 5 varies depending on the size and shape of the fixing portion 3, but is about 3 to 6. The screw hole 5 has a funnel-shaped slope on the surface side.

A cylinder inlet 6 is provided substantially in the center of the surface of the fixed portion 3. Around the cylinder inlet 6, there is a curved introduction portion 9, which is continuous from the surface side of the fixed portion 3 to the inner wall of the cylinder portion 4 in a funnel shape.

The tubular portion 4 is formed integrally with the fixed portion 3 and fits into the insert 2 inserted from the tubular inlet 6. Therefore, the internal cross-sectional shape of the tubular portion 4 corresponds to the cross-sectional shape of the insert 2. In this embodiment, the cylindrical portion 4 has a square internal cross section, but may have a triangular, circular, rectangular, pentagonal, or hexagonal cross sectional shape. The side opposite to the cylinder inlet 6 of the cylinder portion 4 is an opening.

At least one of the inner walls of the tubular portion 4 may be provided with the thick pressing portion 7, but normally, the inner walls facing each other are
That is, two are provided. In another embodiment, in the case of an inner wall having a square or polygonal cross-sectional shape, it may be provided on two or more inner wall surfaces.

The thick pressing portion 7 is formed between a plurality of parallel slits 8 formed in the wall surface of the cylindrical portion 4. Therefore, the width and length of the thick pressing portion 7 are determined by the slit 8. The number of the slits 8 is usually two in parallel and spaced apart from each other, but may be more. In this embodiment, the width of the slit 8 may be 1 mm, and the length may be about 60 to 80% of the length of the cylindrical portion 4, that is, 40 mm, that is, 25 mm. The width of the thickness pressing portion 7 is 5 times the width of the inner wall surface of the cylindrical portion.
Approximately 70%, and in this embodiment, 5 mm.
