Universal fixing metal fitting for operating table

Abstract

An object of the present invention is to provide a universal fixing metal fitting 1 for an operating table capable of being easily attached and detached, capable of enabling simultaneous firm fixing between the fixing metal fitting, an appliance to be fixed, and an accessory attachment table by performing fastening one time regardless of the existence/nonexistence of a sheet or the like, capable of ensuring the same firm fixing even when the shape of the accessory attachment table is changed and capable of fixing no matter what the shape of the appliance to be fixed is. To achieve the above-described object, there is provided a universal fixing metal fitting 1 for an operating table characterized by having a base member 2 in which a first attachment leg 2 b having an attachment portion 2 d and including a slant portion 2 h formed thereon and a second attachment leg 2 c having an attachment portion 2 e and including a slant portion 2 i formed thereon are formed continuously with a flat portion 2 a having a screw-engaging hole 2 k formed at its center, an upper pinching member 3 in which a first pinching portion 3 b is formed continuously with one end of a connecting portion 3 a having a V-cut 3 k at its center and L-cuts 3 d formed continuously with the V-cut 3 k, and in which a second pinching portion 3 c is formed continuously with the other end of the connecting portion 3 a, a lower pinching member 4 in which a third pinching portion 4 b is formed continuously with one end of a connecting portion 4 a having a V-cut 4 k at its center and L-cuts 4 d formed continuously with the V-cut 4 k, and in which a fourth pinching portion 4 c is formed continuously with the other end of the connecting portion 4 a, and a fastening portion 5 in which a handle 5 c having spherical stoppers 5 d provided on its opposite ends is loosely fitted in a through hole 5 f in a cylindrical head portion 5 a provided on one end of a screw-engaging shaft 5 b, the universal fixing metal fitting 1 also characterized in that when the upper pinching member 3 and the lower pinching member 4 are coupled to the base member 2, coil springs are attached by being interposed between the first pinching portion 3 b and the attachment portion 2 d, between the second pinching portion 3 c and the attachment portion 2 e, between the third pinching portion 4 b and the attachment portion 2 d and between the fourth pinching portion 4 c and the attachment portion 2 e, and in that the screw-engaging shaft 5 b is mounted in the screw-engaging hole 2 k when the fastening portion 5 is coupled to the base member 2. There is also provided a universal fixing metal fitting 1 for an operating table having the above-described features and also characterized in that a pressing member 5 e is attached to a tip of the screw-engaging shaft 5 b.

1 . A universal fixing metal fitting for an operating table characterized by comprising a base member in which a first attachment leg having an attachment portion and including a slant portion formed thereon and a second attachment leg having an attachment portion and including a slant portion formed thereon are formed continuously with a flat portion having a screw-engaging hole formed at its center, an upper pinching member in which a first pinching portion is formed continuously with one end of a connecting portion having a V-cut at its center and L-cuts formed continuously with the V-cut, and in which a second pinching portion is formed continuously with the other end of the connecting portion, a lower pinching member in which a third pinching portion is formed continuously with one end of a connecting portion having a V-cut at its center and L-cuts formed continuously with the V-cut, and in which a fourth pinching portion is formed continuously with the other end of the connecting portion, and a fastening portion in which a handle having spherical stoppers provided on its opposite ends is loosely fitted in a through hole in a cylindrical head portion provided on one end of a screw-engaging shaft, the universal fixing metal fitting also characterized in that when the upper pinching member and the lower pinching member are coupled to the base member, coil springs are attached by being interposed between the first pinching portion and the attachment portion, between the second pinching portion and the attachment portion, between the third pinching portion and the attachment portion and between the fourth pinching portion and the attachment portion.
