Abstract: The invention relates to a device (5) for supporting and for movably guiding a chair (6) in a slotted guide (8, 8.1, 8.2), which is provided in a housing (7) and is designed as an elongated hole guide, having a carriage (10) that can be moved in the slotted guide (8, 8.1, 8.2) and supports a chair receptacle (9) of the chair (6). In order to be able to use this device in a more varied manner, according to the invention, the slotted guide (8, 8.1, 8.2) has at least two slotted guide tracks (13, 14), between which an adjustable track switch (12) is provided in order to transfer the chair (6) out of the one slotted guide track (13) into the other slotted guide track (14), and vice versa.

Abstract: management device for managing the expiration date of food and drink arranged on a plate and including a camera for capturing a two-dimensional code on a cylindrical base of the plate, a barcode scanner for analyzing the two-dimensional code captured by the camera and extracting a plate number, a management main body for receiving the plate number output from the barcode scanner and collectively managing the traveling plates, and a DIO (Digital Input/Output) module. The DIO module is connected to a detection switch disposed on a downstream position of the camera and a discharge mechanism disposed on a downstream side of the detection switch to perform a bidirectional communication with the management main body. A separation distance between the camera and the detection switch is shorter than a diameter of the plate.

Abstract: In circulating type food and drink transport apparatus (EQU), a plurality of plates (5A) is located on a circular link chain (4) including a chain driving section (DV) and a chain driven section (FR) with a predetermined clearance. The circular link chain is guided and carried by a traveling lane (1). The lower portion of the traveling lane is closed using a substantially U-shaped receiver (9). The chain driving section and the chain driven section are movable in accordance with a manual operation. The link chain is loosened, and thereby, the traveling lane (1) is securely cleaned.

Abstract: A preferred embodiment of a dining unit includes a first case for at least one of holding, displaying, and serving food products. The first case includes at least one of a tray and a shelf. The dining unit also includes a second and a third case for at least one of holding, displaying, and serving others of the food products. The second and third cases each have a substantially wedge-shaped planform, and the first case is positioned between the second and third cases.

Abstract: A unit is described, consisting of an oblong table and a plurality of seats arranged approximately the same distance apart around the perimeter of the table. The unit includes elements designed to move the plurality of seats along en masse around the perimeter at a predetermined speed.

Abstract: The invention relates to a circulative catering bar equipped with warming system and cold air circulation system which comprises a warming system in which a heater (26) is incorporated in a plate mounted on the crescent chain, a cold air circulation system having cold air paths formed beneath the refrigerating conveyor and circulating cold air onto the refrigerating conveyor, and a setting board (56), disposed above said warming system, and it is possible to cyclically convey ordinary goods, warmed goods and refrigerated goods at the same time by cyclically conveying ordinary goods and warmed goods on a crescent chain of the warming system and cyclically conveying refrigerated goods on the refrigerating conveyor.

Abstract: A circulative catering table provided with an endless conveyer circulating according to the circulating course supported in a horizontal plane at the designated height by a base frame and supporting the foods at the designated intervals, an appropriate number of counters for eating and drinking disposed outside of the endless conveyer and a cooling system for the foods on the endless conveyer. The circulative catering table has a first cool air path forming a lower opening by providing a gap between the outside of the endless conveyer and the counter and extending downwards of the base frame in communication with the lower opening and a second cool air path disposed in opposition to the lower opening against the endless conveyor, with the lower part thereof in communication with the first cool air path and with the upper opening at the upper end that uniformly blows out the cool air in a direction crossing the endless conveyer and toward the space above the lower opening.

Abstract: A self-service apparatus is provided to be operated by a user for selectively serving foods or drinks. The self-service apparatus includes a support and a cover fixedly supported by the support for covering foods and drinks. A shaft is suspended from the support, and a rotary disk is rotatably mounted on the shaft to be rotated about the shaft upon actuation of a lever. Servers are carried by the rotary disk and hold a food portion or drink. A desired food portion or drink may be selectively served to the user by operating the lever at a desired position.

Abstract: A circulative catering table having a counter and an endless path of travel for dishes and meals, provided in the counter, at least a bypass path of travel is provided, dishes containing therein meals, which have been transferred on a going path portion of the endless path of travel, are led to the bypass path of travel by an arm member for guide rotatably provided and having a length larger than the width of the path of travel, and subsequently, led to a returning path portion of the endless path of travel by another arm member for guide on the returning path portion, whereby a suitable circulative path is formed by the endless path of travel and the bypass path of travel.
