A surgical table including a patient support including a head end section including a pair of head end frames joined with a foot end section including a pair of foot end frames, each of the head end frames is inwardly joined with one of the foot end frames at a hinge. Each of the hinges including a drive chain positioned within the foot end frame and including a plurality of drive links coupled together, the drive chain coupled at opposite ends to a sprocket and a drive link, the sprocket being rotatably coupled with the head end section via a hinge pin. The drive link operably coupled with a motor to move the drive link within the foot end frame so as to move the drive chain and cause the sprocket to rotate such that the head end section articulates relative to the foot end section about the hinge pins.

A hinged component includes a polyethylene composition. The polyethylene composition includes high density polyethylene having a density between 0.941 g/cm.sup.3 and 0.960 g/cm.sup.3 as determined according to ASTM D792, a melt index (MI) of less than 7 g/10 min as determined according to ASTM D1238 (2.16 kg/190 C.), and a weight average molecular weight (Mw) of more than 170,000.

A hinge structure includes two leaves with locking holes and a pivot adapted to be in connection with the two leaves, where each leaf is made of polymer composite carbon fiber and pivot is a pivoting piece made of aromatic polyamide curtain fabric, where the pivoting piece is sandwiched between the two leaves and bonded together therewith by means of thermosetting molding to form a sheet body. The present invention is silent without needing maintenance, labor-saving in door opening and closing, long in hinge life, light-weighted in weight, thin in thickness and good in strength.

A hinge for a refrigerator includes a hinge support configured to be mounted on a front surface of a cabinet of the refrigerator, where the hinge support has a plate shape and defining a coupling hole, a hinge bracket including an insertion part configured to be inserted into the coupling hole, where the hinge bracket is coupled to the hinge support along a longitudinal direction of the hinge support, and a hinge pin that is configured to mount to the hinge bracket and that is configured to allow a door of the refrigerator to rotate about the hinge pin. The hinge support includes a bracket support that at least partially surrounds the coupling hole and protrudes from a front surface of the hinge support, the bracket support being configured to provide support to the hinge support.
