However, at such a food counter,
In order to transport foods such as sushi and raw meat for yakiniku in a hygienic manner while preventing the adhesion of dust and insects, an enclosure having a transparent window is provided over the conveyor.

In such a food and beverage counter equipped with a conventional enclosure, the transparent window for taking out food and drinks is provided with a sliding door that opens and closes in the left and right directions or a door that opens and closes by moving up and down. A sensor is installed in front of the dining counter to detect when a customer is seated at a table and automatically open the door.

(c) Problems to be solved by the invention However, in this case, the operating mechanism for the opening/closing door is located in a limited space on the side wall of the food and beverage counter. However, in order to make the door operate smoothly,
It is necessary to move the left and right sides of the opening/closing door at the same time, and for this reason, in conventional food counters, the movement mechanism requires many links and many gears, making the mechanism complicated and large-scale. As a result, it was expensive and required a lot of space, which was a problem.

The present invention aims to solve the problems associated with the opening/closing mechanism of the opening/closing door in a food and beverage counter.

(d) Means for solving the problems The object of the present invention is to provide a food and drink counter equipped with a door opening/closing device that has a simple mechanism and does not require space.

The present invention includes a conveyor for conveying food and beverages, and an enclosure is provided on the conveyor, and the enclosure has an upper position when closed and a lower position when opened, and is housed in a side wall of a food and beverage counter. In a food and beverage counter equipped with an opening/closing door member, the lower end of the opening/closing door member is held by a support body, and the opening/closing door member is held in a horizontal slot formed at a first side end of the support body. , a guide provided at the upper end of the first link is movably engaged with the first link, and the lower end of the first link is connected to the first link horizontally suspended below the opening/closing door member. The guide element is rotatably supported by the engaging portion at the second end of the fixed frame, and is provided at the lower end of the second link cross-connected to the first link. , is movably engaged with a horizontal slot formed in the first side engagement part of the first fixed frame, and the upper end of the second link is connected to the opening/closing door. A connecting member that is rotatably supported by the engagement portion at the second end of the support and cross-supports the first link and the second link is horizontally suspended above the support. The food counter is provided with an opening/closing door, which is rotatably supported at the end of a cylinder rod of an air cylinder supported by a second fixed frame.

In the present invention, the opening/closing door member forms part of the side wall of the enclosure that surrounds the conveyor, and is made of, for example, a transparent plate-like member, and has both ends so that it can move smoothly in the vertical direction. is engaged with the guide groove.

In the present invention, the opening/closing door member is movably supported by a link mechanism including two links that intersect with each other.

In the present invention, the opening/closing door member is provided with a support member for link engagement at the lower part. The support member includes a link so that the upper part of the link can be moved when opening and closing.
For example, a guide groove for guiding the upper end of the link is formed. The support member may be formed integrally, or may be formed by being divided as appropriate. It is also possible to provide a support member for each engagement groove.

In the present invention, the links intersect at a point of action to which a reciprocating rod, such as a piston rod of an air cylinder or a rack of a rack and pinion mechanism, is connected for use. In this case, the link corresponds to the movement of this reciprocating rod,
Extends and contracts. The extension of the link causes the opening/closing door member to rise, and the opening/closing door member performs a closing operation of the opening/closing portion. On the other hand, the contraction of the link brings about the lowering of the opening/closing door member, and the opening/closing door member performs an opening operation of the opening/closing portion.

A reciprocating device such as an air cylinder is provided with a cylinder portion fixed to a fixed frame located above or below a fixed frame that engages a lower end of the link.
When the reciprocating device is installed above the fixed frame that the lower end of the link engages with, the door member will be fully opened when the stroke of the reciprocating rod of the reciprocating device reaches its maximum, and the stroke will increase. At the minimum point, the opening/closing door member is closed. In this case, the moving stroke of the opening/closing door member and the operating stroke of the reciprocating device overlap, which is preferable because the space factor is reduced.

In the present invention, in order to smooth the operation of the links, the lower end of the first link is rotatably supported, for example, pivoted, on the fixed frame, but the upper end of the other first links and the The upper and lower ends of the two links are movably supported on respective supports.

In the present invention, the support movably engaged with the link is provided with a horizontally blind or through slot, while the upper or lower movable end of the link engaged therewith is provided with a horizontally blind or penetrating slot. A guide element, such as a pin, is provided to be inserted into the slot and movable along the slot.

(e) Function In this invention, the opening/closing door member is supported by two intersecting links, and the intersection of the links is used as the point of action, so that the two links are moved by the reciprocating movement of the reciprocating rod of the reciprocating device. By expanding and contracting the intersecting link devices, the opening/closing door member of the food and beverage counter can be opened and closed.

Moreover, according to the present invention, the structure is simple, consisting of two links and the reciprocating device connected, fewer parts are used, and the opening/closing mechanism can be manufactured at low cost.

Moreover, in the present invention, since this is done using, for example, an air cylinder, the opening/closing door can be opened after confirming the number of customers using a sensor.

(F) Examples Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited in any way by the following explanations and examples.

FIG. 1 is a partially cutaway schematic explanatory diagram showing an embodiment of the present invention, and FIG. 2 is a schematic diagram showing the opening/closing mechanism of the opening/closing window in the embodiment of FIG. 1. FIG.

In this example, the eating and drinking counter 1 has a cover 4 formed to surround the upper part of the crescent conveyor 3 of the single lane 2, and a counter 5 formed on the outside. In this example, a sliding door 7 is formed on the inside 6 of the cover surrounding the lane, and on the other hand, on the outside 8, that is, on the side of the counter 5, an opening/closing window 9 that can be opened and closed vertically is provided. The link mechanism 10 that opens and closes the opening/closing window 9 has two links crossing each other via a pin 11, and a guide 12 (only one of which is shown) at the upper end is connected to the bottom of the opening/closing window 9. movably engaged. The tip end 15 of the piston rod 14 of the air cylinder 13 is connected to a connecting element 16 that connects the intersecting links to each other via a pin 11. An optical sensor 18 is provided on the back surface 17 of the counter 5. The output of the optical sensor 18 is connected to a drive circuit (not shown) for the air cylinder 13.

Since this example is configured in this way, the customers sitting in the customer seats (not shown) can be, for example,
It is sensed by the optical sensor 18 and the signal is sent to the drive circuit of the air cylinder 13.
can be activated to automatically open the opening/closing window 9.

Therefore, the customer can automatically open the opening/closing window 9 in front of the customer's seat of the food and beverage counter 1 without any particular effort just by sitting on the seat. Therefore, customers can take out and eat the food and drink delivered through the lane 2 in the food and beverage counter 1 as appropriate by simply sitting at the customer's seat without having to open the opening/closing window themselves.

In particular, in this example, since the optical sensor 18 is installed on the back side of the counter 5, it is possible to prevent the optical sensor 18 from malfunctioning due to store staff moving around the store, for example, by using a chair with a back. can.

In FIG. 2, the air cylinder 13 is held on the upper support beam 19 by a holding member 20 such as a fixing pin. The tip 15 of the piston rod 14 of the air cylinder 13 is connected to a connecting element 16.

In this example, this connecting element 16 allows two intersecting links 21 and 22 to rotate relative to each other.
A link holder is connected via a pin 11 at the intersection.

The link 21 has a lower end 23 fixed to a lower support beam 24 via a bracket 25, and an upper end 26 of the link 21 is connected to a guide groove of a slide portion 28 formed at one end of a holder 27 of the opening/closing window 9. 29 through a slide pin (not shown). On the other hand, the link 22 is attached at its lower end 30 to the lower support beam 25 by the slider 3
1 through a slide pin 33, and is movably supported at the upper end 34 by a slide portion 35 formed at the other end of the holder 27 of the opening/closing window 9. ing.

Since the present example is constructed as described above, the air cylinder 13 operates to push down the piston rod 14 to the position shown in FIG. 2 in response to a signal from the optical sensor 18. When the piston rod 14 is pushed down, the link holder 16 is lowered and the links 21 and 22 are rotated about the pin 11 at the intersection and contracted. The expansion and contraction of the links 21 and 22 allows the opening/closing window 9 held by the holder 27 to be moved through the guide portion 3.
6 and 37, and the opening/closing window 9 of the food and beverage counter is opened. When the customer leaves his/her seat, the air cylinder 13 receives a signal from the optical sensor 18 and operates to pull up the piston rod 14. When the piston rod 14 is pulled up, the link holder 16 rises and rotates about the pin 11 at the intersection in the direction in which the links 21 and 22 are separated, thereby expanding the links 21 and 22. Expansion of the links 21 and 22 causes the opening/closing window 9 to rise along the guide portions 36 and 37, and the opening/closing window 9 of the eating/drinking counter 1 is closed.

In this example, the air cylinder is fixed to the upper support beam with the piston rod facing downward, but it can of course be fixed to the lower support beam with the piston rod facing upward.

Although this example concerns a single lane, an appropriate lane arrangement such as a double lane can be used.

(g) Effects of the invention In this invention, the opening/closing mechanism connected to the support frame of the opening/closing door member of a food and beverage counter is formed by two links that intersect with each other and a reciprocating device equipped with a reciprocating rod that acts on these intersections. Therefore, compared to the opening/closing mechanism of the opening/closing door member of a conventional food and beverage counter, the number of parts is fewer.
Since the structure is simple, it is easy to assemble and can be installed without requiring much space.
