1. A food and drink conveying device, comprising:
a travel path having a curved path in at least one portion, said travel path comprising a protruding rail provided at a center of the travel path, said protruding rail having a top surface interposed between two vertical side surfaces; a conveyor driving body provided along the travel path; a travel body on which food and drink are placed and which travels along said travel path; and a linking means for linking said conveyor driving body to said travel body, wherein said linking means consists of a first linking member slidably attached to said travel body and a second linking member attached to said conveyor driving body, said travel body travels along said travel path when said conveyor driving body is driven, said travel body comprises a travel body main unit that is driven and conveyed, and a leading body provided at a front end of the travel body main unit in the direction in which the travel body travels, the leading body is supported by said travel body main unit so as to be pivotable around an axis in a horizontal plane so as to follow a form of the rail upon entering a curve of the rail, the leading body is formed of a roller bracket that travels over the rail and comprises two pairs of contact sections attached to the leading body, each of said pairs of contact sections comprises a front contact section and a rear contact section, the first pair of said contact sections is attached to the leading body on a first side of said leading body in a widthwise direction relative to the direction in which said travel body travels, the second pair of said contact sections is attached to the leading body on a second side of said leading body in the widthwise direction relative to the direction in which said travel body travels, said pairs of contact sections are aligned on either side in the direction in which said travel body travels on both outer sides of the two vertical side surfaces of the protruding rail, the pair of contact sections provided on an inner side of said curved path make contact with the vertical side surface of the protruding rail of said travel path in two locations in said curved path, such that, as the leading body enters the curve of the rail, the pair of contact sections provided on the inner side of the rail making contact in two locations regulates further rotation of the leading body around the axis such that the rotation of the leading body matches the curve of the rail, the first linking member moves in said travel body main unit so as to follow the second linking member, as the leading body enters the curve of the rail, said travel body further comprises a following body provided at a rear end of said travel body main unit, the following body is supported by said travel body main unit so as to be pivotable around an axis in a horizontal plane so as to follow a form of the rail upon entering a curve of the rail, the following body is formed of a roller bracket that travels over the rail and comprises two pairs of contact sections attached to the following body, each of said pairs of contact sections comprises a front contact section and a rear contact section, the first pair of said contact sections is attached to the following body on a first side of said following body in a widthwise direction relative to the direction in which said travel body travels, the second pair of said contact sections is attached to the following body on a second side of said following body in the widthwise direction relative to the direction in which said travel body travels, said pairs of contact sections are aligned on either side in the direction in which said travel body travels on both outer sides of the two vertical side surfaces of the protruding rail, and the pair of contact sections of the following body provided on an inner side of said curved path make contact with the vertical side surface of the protruding rail of said travel path in two locations in said curved path, such that, as the following body enters the curve of the rail, the pair of contact sections of the following body provided on the inner side of the rail making contact in two locations regulates further rotation of the following body around the axis such that the rotation of the following body matches the curve of the rail. |
