Description

Field of technology to which the utility model belongs

The utility model relates to aqua vending machines, i.e. to water vending machines by means of automatically controlled dispensing of water into a water buyer's container installed in the water loading chamber of the aqua vending machine.

State of the art

Known is the door of the water filling chamber of the aqua vending apparatus, which is made automatic with a drive and position sensors that control its position, while the door is made in an anti-vandal and all-weather version, restricts access to the filling chamber and, as follows from the context, is an entirely metal plate (see description of the utility model to the patent RU No. 139049 U1, published on 10.04.2014 Bull. No. 10).

The features of the known door, which are common with the features of the claimed technical solution, consist in making the door entirely in the form of a metal sheet.

The reason that prevents obtaining the result in the known door, which is provided by the claimed technical solution, is that the known door is entirely made of metal, which makes it impossible for the buyer to view the interior of the filling chamber when the door of this chamber is closed.

A well-known door of the loading chamber of an aqua-vending apparatus (prototype), which is a plastic plate of light-transmitting material that allows the buyer to view the interior of the water loading chamber with the door of this chamber closed, while the door is made of monolithic polycarbonate, protected from ultraviolet radiation, and is made opening to the left relative to the buyer of water (see the description of the invention to the patent RU No. 2711689 C1, IPC B67D 7/00, published on January 21, 2020 in Bull. No. 3).

Signs of a well-known door (prototype), common with the signs of the claimed technical solution, is that it (known door) contains a plastic plate of light-transmitting material.

The reason that prevents obtaining in the known design of the door (prototype) the technical result, which is provided by the claimed technical solution, is that it (the well-known loading chamber door) is entirely made of plastic, which reduces its strength in terms of its hinged fastening due to relatively low strength plastics.

The technical problem to be solved by the technical solution claimed for patenting is the need to increase the strength of the door in terms of the hinged fastening of this door while maintaining the possibility for the buyer to view the interior of the filling chamber through this door in its closed state. Disclosure of the essence of the utility model

The technical result, mediating the solution of this technical problem, is to make the desired door combined (metal plus light-transmitting plastic), so that the metal part of this door is intended for hinged fastening of this door, and the plastic part of this door, being made of light-transmitting plastic, is intended for enabling the water buyer to view the interior of the water filling chamber through this door in its closed state. At the same time, an increase in the strength of the hinged fastening of the door is achieved both by making the part of the door directly connected to this hinged fastening made of metal, and by making this part of the door in the form of a corner, which, as you know, is characterized by increased resistance to bending due to the very shape of the corner profile.

The technical result is achieved by the fact that the door of the loading chamber of the aqua vending machine contains a plastic plate made of a light-transmitting material and a bent unequal metal corner, which is designed for hinged fastening of the door, while this corner is overlapped with the plastic plate by its larger shelf, so that part of this the plate is not covered by the specified overlap.

The technical result is also achieved by the fact that:

- the width of the non-overlapped part of the plastic plate exceeds half the width of the door;

- the plastic plate is made of monolithic polycarbonate protected from ultraviolet radiation;

- the specified corner is made with the possibility of attaching to it a means for creating a constant torque in relation to the door in the direction of its closing;

Implementation of the utility model

The door of the filling chamber of the aqua-vending apparatus contains a plastic plate 1 made of a light-transmitting material and a bent unequal-shelf metal corner 2, which is designed for hinged fastening of the door and which contains a large shelf 3 and a smaller shelf 4 (Fig.1-4); in this case, the smaller shelf 4 is made (as an option) with a bend 5, giving an L-shaped form to this smaller shelf (figure 2, 3).

The plastic plate 1 is located parallel to the larger shelf 3 on its inner side, is rigidly overlapped with the larger shelf 3, and either with a full overlap, when it (plate 1) abuts with its edge (left in the figure) against the smaller shelf 4 (figure 1, 2), or with a partial overlap, when there is no specified support (figure 4). In addition, in the embodiment of the corner 2 with a bend 5, which (option) is the main one and is shown in Fig.2, 3, the distance between the inner plane 6 of the bend 5 and the inner plane 7 of the larger shelf 3 is equal to (h+5), where h is the thickness of the plastic sheet 1, and 8 is the technological tolerance due to the possibility of placing the plastic sheet 1 between the bend 5 and the larger shelf 3 with a minimum gap. In addition, at any location of the plastic plate 1 relative to the metal corner 2 (with a full overlap, as shown in Fig.1, 2, or with a partial overlap, as shown in Fig.4), part 8 of the plate 1 is not covered by the specified overlap, so that the width 8 of this (non-overlapped) part is equal to or greater than half the width 9 of the door, which makes it possible for the water buyer to view the interior of the filling chamber with the door closed.

In the preferred embodiment of the door, the plastic plate 1 is made of monolithic polycarbonate, which freely transmits light in the visible range, which increases the strength of the door relative to other plastics (this is a property of monolithic polycarbonate). At the same time, the buyer has the opportunity, with the door closed, through its part 8, to view the interior of the filling chamber, namely, to visually perceive information inscriptions, advertising materials and instructions that are located on the rear wall of the loading chamber from the inside of this wall, and also to visually control the issuance process water into the container of the water buyer, located in the water loading chamber with the door of this chamber closed. In addition, the specified monolithic polycarbonate is made protected from ultraviolet radiation, which increases the service life of both this door due to the protection of plate 1 from its destruction by solar ultraviolet, and those information inscriptions, advertising materials and instructions that are located on the rear wall of the filling chamber from the inside this wall also due to their protection from solar ultraviolet radiation.

The door also contains door hinges (not shown), which are designed to hinge the door on the side wall of the loading chamber (as an option) or, alternatively, on the front shield of the aqua vending machine, so that one of the wings of these door hinges is fixed on a larger shelf 3 corners 2, and others - on the side wall of the filling chamber or on the front shield of the aqua vending machine (this is a well-known hinged version of the hinged door).

Another (non-hinged) version of the hinged fastening of the door is also possible, which consists in making the upper and lower ends of the larger shelf 3 of the corner 2 with perpendicular limbs 10 oriented inside the loading chamber (Fig.5, 7), in which (i.e. in the limbs ) made either holes 11 (figure 5), or fixed vertical pins 12 (figure 7).

In the preferred embodiment of such a (non-loop) hinged mount, the limb 10 of the upper end of the larger shelf 3 has an additional limb 13, to which a spring 14 is attached at one end (i.e., a means of creating a constant torque in relation to the door in the direction of its closing, - Fig.5 ,6), which is fixed at its other end to the side wall of the loading chamber. At the same time, on the bend 10 of the lower end of the larger shelf 3, a vertical pin 12 is fixed (Fig. 7), so that these holes 11 and pin 12 are located on the same vertical axis of this hinged mount, provided on the other hand by the fact that there is a mating pin for the hole 11 loading chamber, installed in the upper part of the loading chamber and entering this hole 11 (this counter pin is not shown), and for pin 12 there is a counter opening of the loading chamber, made in the lower part of the loading chamber, into which this pin 12 enters (this is a counter hole not shown). Thus, two hinged pairs “pin-hole” formed at the top and bottom of the loading chamber provide the desired hinge fastening of the door without the use of door hinges, and the spring 14 installed at the top of the loading chamber ensures the creation of a constant torque in relation to the door in the direction of its closing in order to protection of the internal space of the loading chamber from external pollution and from solar ultraviolet radiation.

In addition, other options for non-hinged hinged fastening of the door are possible, when either both ends (upper and lower) of the larger shelf 3 are made with holes 11, or both ends (upper and lower) of the larger shelf 3 are made with pins 12, so that for each hole 11 provides a reciprocal pin of the loading chamber, and for each pin 12 there is a reciprocal opening of the loading chamber (not shown).

The functioning of the door is as follows.

The door is hinged on the filling chamber of the aqua-vending machine with the help of a metal corner 2, which ensures the necessary anti-vandalism of this hinge and the door as a whole. In this case, due to the action of the spring 14, the door is constantly in the closed position. The buyer intending to purchase drinking water in his (the buyer's) container, while being near the aqua vending machine, through the part 8 of the door that is not overlapped, examines the interior of the filling chamber and, accordingly, the inner surface of the rear wall of this chamber, on which information about water and other information is presented. information of interest to the buyer of water. Next, the buyer of water, overcoming some resistance of the spring 14, opens the door of the loading chamber, which (the door) is temporarily spontaneously fixed in the open state due to a certain bent position of the spring in its stretched position due to the bending of the spring on the edge of the side wall of the loading chamber, after which it installs into the chamber for pouring its container for water into the position required for pouring water, after which he (the buyer) pushes the door with a light force on the door in the direction of its (door) closing, which then spontaneously closes under the action of spring 14. After that, using the user interface aqua-vending apparatus (not shown), the water buyer starts the process of buying and selling water and, corresponding to this process, dispensing a given amount of water into the container of the water buyer located in the water filling chamber. At the same time, in the process of dispensing water into the container of the water buyer, he (the buyer) monitors this process through the part 8 of the door that is not overlapped.
