Description

Food return receiving device for a circular food service establishment

[0001] The present invention relates to a food return receiving device that receives a plate containing food that is returned through a return device in a circular food service store, and more specifically, to a food return receiving device that is formed including a receiving portion that receives a plate containing food, a cover portion that is formed to be openable and closable for covering the plate received in the receiving portion, and an opening and closing portion that connects the receiving portion and the cover portion.

[0002]

[0003] Typically, a conveyor belt sushi system is a system in which food is placed on plates, and the plates are then transported by a conveyor belt, allowing consumers to select and eat the food. This system, in which the conveyor belt rotates around the restaurant and the food is placed on the conveyor belt, allowing consumers to select the food according to their preferences, was first invented in Japan in the late 1950s and is currently used in many restaurants in many countries, including the United States, Japan, and Korea.

[0004] However, in the past, since the plates containing food being returned through the return device were returned with the top open, there was a possibility that the food would dry out and become contaminated during the return process.

[0005] For this reason, in order to prevent the food from drying out and to provide the food hygienically, a method of returning the sushi plate after covering it was used. However, since the customer took the returned plate and cover out from the return device and then grabbed the cover by hand and removed it from the plate, the cover member became contaminated, and the plate and cover had to be washed every time, which was inconvenient.

[0006] Additionally, there was a problem that the covers removed from the plates were left on the table at the guest seat, so the covers piled up together with the plates on the table at the guest seat, making the table top narrow.

[0007]

[0008] Meanwhile, prior art related to a food transport device includes Korean Patent Publication No. 10-2008-0018342.

[0009]

[0010]

[0011] The present invention has been made to solve the problems of the prior art as described above, and provides a food transport receiving device having a receiving portion for receiving a plate containing food, a cover portion formed to be openable and closable for covering the plate received in the receiving portion, and an opening and closing portion connecting the receiving portion and the cover portion, so that food contained in the plate can be prevented from drying out or becoming contaminated, and the cover portion can be easily opened by pushing up the plate without directly touching the cover portion, thereby preventing contamination of the cover portion, and since the cover portion is formed to be openable and closable integrally with the receiving portion, it is possible to prevent covers from being piled up separately on a guest's table.

[0012]

[0013] The problems to be solved by the present invention are not limited to the problems described above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the contents described below.

[0015] In order to achieve the above object, the present invention provides a food transport receiving device comprising: a receiving portion for receiving a plate containing food; a cover portion formed to be openable and closable for covering the plate received in the receiving portion; and an opening / closing portion provided for opening / closing the cover portion and having a slit groove and a coupling protrusion formed therein for coupling with the receiving portion and the cover portion, respectively.

[0016] At this time, the cover part includes a cover; and an extension part extending downward from the rear end of the cover; and the extension part includes a rotation shaft coupled with a slit groove of the opening / closing part; and a friction member formed at the rear end of the extension part; or a roller.

[0017] In addition, the opening / closing part is characterized by including a second part having a first area and a second area formed to fix the cover part in an open or closed state; and a first part that is combined with the second part to form a step at the bottom of the first area of ​​the second part.

[0018] In addition, the second part of the opening and closing part is characterized in that it can rotate relative to the first part.

[0019]

[0020] A food transport receiving device according to the present invention comprises a receiving portion for receiving a plate containing food, a cover portion formed to be openable and closable for covering the plate received in the receiving portion, and an opening and closing portion connecting the receiving portion and the cover portion, thereby preventing food contained in the plate from drying out or becoming contaminated.

[0021] In addition, since the cover is formed integrally with the receiving portion so that it can be opened and closed, it is possible to prevent the cover from being piled up together with the plates on the guest's table.

[0022] In addition, the cover can be opened simply by pushing up the plate without directly touching the cover, thereby preventing contamination of the cover, and thus eliminating the need for frequent washing of the cover.

[0023] In addition, the opening / closing part provided for the opening / closing operation of the cover part is composed of only two parts, and the connection structure is also very simple. The connection structure of the receiving part and the cover part is also very simple, so the probability of device failure is very low and the production cost can also be reduced.

[0076] A food transport receiving device according to an embodiment of the present invention is used in a restaurant equipped with a kitchen (1), tables (3) installed at each customer seat in a hall, and a food transport device (2) such as a conveyor, as shown in FIG. 14, and receives a plate (4) with food on it and returns the plate (4) with food on it from the kitchen (1) to each table (3) while moving circulatingly on the transport device (2).

[0077] The food transport receiving device according to this embodiment of the present invention includes, as shown in FIGS. 1 to 13, a receiving portion (100) for receiving a plate (4) containing food, a cover portion (300) formed to be openable and closable for covering the plate (4) received in the receiving portion (100), and an opening / closing portion (200) provided for opening / closing the cover portion (300) and connecting each component by being respectively coupled to the receiving portion (100) and the cover portion (300).

[0078] The receiving portion (100) is provided to receive a plate (4) containing food, and as shown in FIG. 5, a receiving space (110) for receiving the plate (4) is formed at the top, and a protruding protrusion (111) is formed at the front side of the receiving space to contact the plate (40) and to fix the plate (4) so ​​that it does not shake during transportation.

[0079] In addition, a support (130) is formed at the bottom of the receiving portion (100) to support the food return receiving portion by contacting the top of the return device (2) such as a conveyor belt, and a fastening groove (120) for connection with the opening / closing portion (200) is formed at the bottom rear of the receiving portion (100).

[0080] As shown in FIGS. 8 and 9, the cover part (300) is formed with a cover (320) and an extension part (310) extending downward from the rear end of the cover (320). The extension part (310) is formed with a rotation axis (311) that is coupled with a slit groove (224) formed in the extension part (223) of the first component (220) of the opening / closing part (200) to be described later. The cover part (300) rotates up and down about the rotation axis (311) while being coupled with the opening / closing part (200).

[0081] In addition, an elastic friction member (313) is coupled to the coupling groove (312) formed at the rear end of the extension portion (310), and the elastic friction member (313) is brought into contact with or separated from the first to third areas (211, 212, 221) formed in the first component (220) and the second component (210) of the opening / closing portion (200) to be described later, thereby performing the opening / closing operation of the cover portion (300). At this time, in the present invention, depending on the material of the opening / closing portion (200) and the cover portion (300), it is also possible to not form the elastic friction member (313) or to use a roller that rotates through a rotation axis instead of the elastic friction member (313). In addition, it is also possible to form the elastic friction member (313) integrally with the extension portion (310).

[0082] A detailed description of the operation of the elastic friction member (313) will be provided later.

[0083] The opening / closing part (200) is composed of a first part (220) and a second part (210), as illustrated in FIGS. 6 and 7. The two parts (210, 220) are joined by fitting the protrusion (222) of the first part (220) into the groove (213) of the second part (210). When joined, the third area (221) of the first part (220) is inserted into the inner space (214) of the second part (210) and is positioned between the first and second areas (211, 212) of the second part. At this time, the upper part of the third area (221) of the first part (220) protrudes further forward than the first area (211) of the second part (220), thereby forming a step (227).

[0084] In addition, a contact portion (215) adjacent to the second region (212) is formed at the bottom of the second part (210), and the contact portion (215) contacts the lower part of one side of the plate and is pressed downward, thereby causing the second part (210) to rotate.

[0085] In addition, a slit groove (224) is formed in the extension portion (223) protruding from both sides of the first component (220) to which the rotation axis (311) of the cover portion (300) is coupled, and the cover portion (300) is opened or closed by rotating up and down around the rotation axis (311) coupled with the slit groove (224).

[0086] By the structure as described above, the second part (210) can rotate relative to the first part (220) around the protrusion (222). Specifically, the joint form of the first part (220) and the second part (210) is such that the protrusion (222) of the first part (220) is coupled to the inside of the groove (213) of the second part (210) and is thus rotatable. Referring to the cross-sectional view of Fig. 10, when the first part (220) and the second part (210) are coupled, the inner end (216) of the second part (210) and the inner upper end (228) of the first part (220) are spaced apart by a certain distance. Accordingly, as shown in the cross-sectional view of Fig. 11, when the contact portion (215) of the second component (210) moves downward due to an external force, the first component (220) is fixed, and the second component (210) rotates around the protrusion (222), causing the first region (211) of the second component (210) to move forward. At this time, the second component (210) can rotate until the inner end (216) comes into contact with the inner upper end (228) of the first component (220). In the present invention, the second component (210) is formed so that it can rotate up to a maximum of 7 degrees, and is formed so that the opening operation of the lid (320) is performed when it rotates by 0.3 degrees or more.

[0087] In addition, the first and second regions (211, 212) of the second component (210) are formed in a structure that protrudes further forward than the third region (221) of the first component (220), and accordingly, the first and second regions (211, 212) of the second component (210) are in strong contact with the elastic friction member (313) of the cover portion (300) to form a high pressure.

[0088] Accordingly, when the elastic friction member (313) of the cover part (300) is in contact with the first region (211) of the second component (210), the cover (320) of the cover part (300) is in a closed state, and in this state, the elastic friction member (313) of the cover part (300) is restricted from moving upward by the first region (211) of the second component (210), and is also restricted from moving downward by the step (227) of the first component (220), so that the cover (320) is maintained in a closed state unless an external force is applied.

[0089] In addition, when the elastic friction member (313) of the cover part (300) is in contact with the second area (212) of the second component (210), the cover (320) of the cover part (300) is in an open state, and in this state, since the pressure between the elastic friction member (313) of the cover part (300) and the second area (212) of the second component (210) is high, the cover (320) is maintained in an open state unless an external force is applied.

[0090] Meanwhile, when the cover (320) of the cover part (300) is closed, that is, when the elastic friction member (313) of the cover part (300) is fixed by the first area (211) of the second part (210) and the step (227) of the first part (220) as shown in FIGS. 10 and 12, and the guest holds and pushes up one side of the plate (4) accommodated in the accommodation space (110) of the accommodation part (100), since the lower part of one side of the plate (4) is restricted from moving forward by the protruding step (111) of the accommodation part (100), the one side of the plate (4) moves upward while the movement in the left and right direction is restricted, and accordingly, the other side of the plate (4) is lowered, and as shown in FIG. 13, the lower surface of the other side of the plate (4) presses the contact part (215) of the second part (210) downward. The contact portion (215) is lowered. At this time, as illustrated in FIG. 13, the upper surface of the other side of the plate (4) is brought into contact with the upper surface of the receiving groove (226), thereby serving as a fulcrum of the lever principle, thereby enabling the rotation of the second component (210) with a small force. That is, in the lever principle, the one side of the plate (4) becomes the force point, the point where the upper surface of the other side of the plate (4) and the upper surface of the receiving groove (226) come into contact becomes the fulcrum, and the point where the lower surface of the other side of the plate (4) and the contact portion (215) of the second component (210) come into contact becomes the point of application.

[0091] As described above, as the contact portion (215) of the second component (210) descends, the second component (210) rotates, and the first region (211) moves forward, pushing the elastic friction member (313) of the cover portion (300), so that the elastic friction member (313) is detached from the step (227) of the first component (220), quickly passes the third region (221) of the first component (220), and then comes into contact with the second region (212) of the second component (210), where it is stopped by strong pressure. In this state, if no external force is applied, the cover (320) of the cover portion (300) is maintained in an open state. At this time, only the force that presses the other side of the plate (4) downwards on the contact portion (215) is described above, but the force that presses the upper part of one side of the plate (4) upwards on the cover (320) also plays an auxiliary role in opening the cover (320).

[0092] As a result, when an external force is applied while the cover (320) is closed, the cover (320) operates in a manner that the cover (320) quickly opens as if it were to pop up and then stops. Specifically, when the cover (320) is closed, the extension (310) of the cover part (300) is pressed by the first region (211), pressure is generated and deformation occurs in the cover part (300). Then, when the second part (210) rotates and the first region (211) presses the elastic friction member (313), strong pressure is generated and additional deformation occurs in the cover part (300). In this state, the moment the elastic friction member (313) leaves the first region (211), the force generated by the strong pressure between the first region (211) and the elastic friction member (313) and the force generated when the shape of the extension (310) of the cover (300) is instantly restored to its original state by the restoring force causes the cover (320) to quickly open as if it were popping up.

[0093] Meanwhile, when closing the cover (320) of the cover part (300), if the upper part of the cover (320) is pressed by hand and an external force greater than the critical point (a force greater than the frictional force between the elastic friction member (313) and the second region (212)) is applied, the elastic friction member (313) of the cover part (300) leaves the second region (212) of the second component (210) and passes through the third region (221) of the first component (220) and is fixed by the first region (211) of the second component (210) and the step (227) of the first component (220) as shown in FIGS. 10 and 12, and the cover (320) of the cover part (300) is closed. In this state, if no external force is applied, the cover (320) is maintained in the closed state.

[0094] Meanwhile, a connecting projection (225) that is fitted into the fastening groove (120) of the receiving portion (100) is formed at the lower end of the first component (220), and a receiving groove (226) is formed into which one edge of the plate (4) is inserted into the lower end of the slit groove (224) formed in the extension portion (223) of the first component (220). The plate (4) inserted into the receiving groove (226) is fixed so that it does not shake during return by having the upper end and the side of one edge contact the receiving groove (226), as shown in FIGS. 2 and 4.

[0095] The food transport receiving device according to the embodiment of the present invention described above will become clearer through the description of the method of operating the food transport receiving device described below with reference to FIGS. 1 to 10.

[0096] First, after the cook places food on a plate (4), he holds the edge of the plate (4) with his hand and places the plate (4) on the receiving space (110) of the receiving section (100) of the food return receiving device placed on the return device (2) with the cover (320) of the cover section (300) open.

[0097] In this state, the elastic friction member (313) of the cover part (300) is in contact with the second area (212) of the second component (210), and since the frictional force between the elastic friction member (313) of the cover part (300) and the second area (212) of the second component (210) is high, the cover part (300) is maintained in an open state unless an external force is applied.

[0098] Afterwards, when the cook presses the top of the cover (320) of the cover part (300) with his / her hand and applies an external force greater than the critical point (a force greater than the frictional force between the elastic friction member (313) and the second area (212), the elastic friction member (313) of the cover part (300) leaves the second area (212) of the second part (210) and passes through the third area (221) of the first part (220) and is fixed by the first area (211) of the second part (210) and the step (227) of the first part (220) as shown in FIGS. 10 and 12, and the cover (320) of the cover part (300) is closed. In this state, if no external force is applied, the cover (320) is maintained in the closed state.

[0099] As described above, in the present invention, food on a plate (40) is returned to the customer while covered with a cover (320), so that the food on the plate can be prevented from drying out or becoming contaminated.

[0100] Meanwhile, when a customer lifts the plate (4) by holding the side portion of the plate (4) that is partially protruding outward from the front edge of the cover (320) as shown in FIGS. 1 and 3, the lower portion of one side of the plate (4) is restricted from moving forward by the protruding jaw (111) of the receiving portion (100), so that the one side of the plate (4) moves upward while the movement in the left and right directions is restricted, and accordingly, the other side of the plate (4) is lowered, and as shown in FIG. 13, the lower surface of the side portion of the other side of the plate (4) presses the contact portion (215) of the second component (210) downward, causing the contact portion (215) to be lowered. At this time, as illustrated in FIG. 13, since a point on the upper surface of the other side of the plate (4) comes into contact with a point on the upper surface of the receiving groove (226), it serves as a fulcrum of the lever principle, so that the second component (210) can be rotated even with a small force. That is, in the lever principle, one side of the plate (4) becomes the force point, the point where the point on the upper surface of the other side of the plate (4) and a point on the upper surface of the receiving groove (226) come into contact becomes the fulcrum, and the point where the lower surface of the other side of the plate (4) and the contact portion (215) of the second component (210) come into contact becomes the point of application.

[0101] As described above, as the contact portion (215) of the second component (210) descends, the second component (210) rotates, and the first region (211) moves forward, pushing the elastic friction member (313) of the cover portion (300). As a result, the elastic friction member (313) detaches from the step (227) of the first component (220), quickly passes the third region (221) of the first component (220), and then comes into contact with the second region (212) of the second component (210) and stops due to a strong frictional force. In this state, if no external force is applied, the cover (320) of the cover portion (300) is maintained in an open state. At this time, only the force that presses the other side of the plate (4) downwards on the contact portion (215) is described above, but the force that presses the upper part of one side of the plate (4) upwards on the cover (320) also plays an auxiliary role in opening the cover (320).

[0102] As a result, when an external force is applied while the cover (320) is closed, the cover (320) operates in a manner that the cover (320) quickly opens as if it were to pop up and then stops. Specifically, when the cover (320) is closed, the extension (310) of the cover part (300) is pressed by the first region (211), pressure is generated and deformation occurs in the cover part (300). Then, when the second part (210) rotates and the first region (211) presses the elastic friction member (313), strong pressure is generated and additional deformation occurs in the cover part (300). In this state, the moment the elastic friction member (313) leaves the first region (211), the force generated by the strong pressure between the first region (211) and the elastic friction member (313) and the force generated when the shape of the extension (310) of the cover (300) is instantly restored to its original state by the restoring force causes the cover (320) to quickly open as if it were popping up.

[0103] As described above, in the present invention, the cover (320) can be opened simply by pushing up the plate (4) without directly touching the cover (320) of the cover part (300), thereby preventing contamination of the cover (320), and accordingly, there is no need to frequently wash the cover (320).

[0104] In addition, since the cover (320) is formed integrally with the receiving portion (100) so as to be openable, it is possible to prevent the cover from being piled up together with the plate on the guest's table (3).

[0105] Meanwhile, the joint structure of each component of the food transport receiving device of the present invention is described as follows.

[0106] That is, the opening / closing part (200) is composed of only two parts, the first part (220) and the second part (210), and the two parts (210, 220) can be simply combined in such a way that the protrusion (222) of the first part (220) is fitted into the groove (213) of the second part (210), and when the first and second parts (220, 210) are combined, the rotation axis (311) of the cover part (300) is simply combined by being coupled to the slit groove (224) formed in the extension (223) of the first part (220), and the receiving part (100) and the opening / closing part (200) are simply combined by being coupled by being coupled to the fastening groove (120) of the receiving part (100) in the coupling protrusion (225) of the first part (220). The opening and closing part (200) is combined.

[0107] When disassembling, disassembly is simple and can be done in the reverse order of the process described above.

[0108] As described above, the opening / closing unit (200) provided for the opening / closing operation of the cover unit (300) is composed of only two parts, and the connection structure is also very simple. The connection structure with the receiving unit (100) and the cover unit (300) is also very simple, so the probability of device failure is very low and the production cost can also be reduced.
