Patent Description:
In the state of the art, there are known various types of doors used as structural elements in cabinets, lockers or luggage storage rooms, in which the key aspect is to ensure the security of the stored content. Particularly noteworthy are devices for storing parcels in the form of parcel lockers, which are a system of post office boxes, used to store parcels with the option of collecting or leaving the parcels at a time convenient for the user. For this reason, they are characterized by simple construction, durability and ease of production and assembly. They are also usually resistant to burglary attempts. Cabinets of this type usually contain many lockers of various sizes. Individual lockers are provided with a door controlled usually by one control unit, located in an area of the cabinet that is easily accessible to the user. In such devices, security and communication means are often used, consisting of sensors, cameras or lighting elements.

In the prior art, cabinet door is known for use in cabinets, including constructions provided with electronically controlled locks. Patent description <CIT> discloses a cabinet door made of a sheet of metal constituting a front panel and containing side walls in the form of an inner edge as well as the upper and lower edges of the front panel, which are bent at right angles to the inside of the cabinet body constituting an internal edge, an upper edge and a lower edge, respectively. Furthermore, the upper and lower edges are bent upwards and protect the construction against water entering the cabinet, ensuring water drainage to the outside. Furthermore, the upper edge of the front panel contains a hinge hole in which a Teflon sleeve is mounted, constituting an electroinsulator in the entire construction, allowing to eliminate or significantly reduce the phenomenon of electrochemical corrosion. The cabinet door is attached to the cabinet body with spacers in the form of brackets in the form of a flat sheet. In this solution, the door has a simple construction and prevents the potential difference and, consequently, corrosion resulting from the difference in materials of which the door and the cabinet body are made. Furthermore, the door can be provided with a grounding pin and a metal cable attached to the inside of the locker.

While from the document <CIT> there is known a method of delivering a parcel to a recipient, which uses a system of post office boxes and enables an identification of an appropriate locker in a cabinet with the assembly of lockers, depending on the size of the delivered parcel. The cabinet with the assembly of lockers is provided with a central communication and control unit ensuring access control to each locker by controlling the locking mechanisms that each locker is provided with. In this solution, it is disclosed that each locker can be assigned with a light indicator for informing the user of the accessibility of the locker. The presented system is configured in such a way as to control access to each of the cabinets by using at least one locking mechanism, suitably compatible with each cabinet. Furthermore, one of embodiments discloses a cabinet with at least one light indicator configured to inform the user which of the individual cabinets is unlocked or accessible.

In the state of the art, a device acting as a parcel exchange point is also known from the <CIT>. The device has the form of a cabinet containing storage lockers of various sizes, depending on the individual dimensions of the parcel. The outer part of individual lockers are doors that can be provided with slots for letters. The door has a lock, which protects against uncontrolled opening of the locker. The lock can include a latch member, a latch engagement and disengagement member that are remotely controlled and consequently lock the door movement. The door of the locker is pivotally connected to one of the walls of the cabinet by means of at least one hinge. In this way, it is possible to rotate the door in relation to the locker and the cabinet. What's more, in order to facilitate use and provide information which of the lockers is accessible, an illuminating element has been installed inside the locker or on its door, which can be a light bulb, LED diode or any other light emitting object. The light effect varies depending on the accessibility of individual lockers. Depending on the configuration, the light on or off will signal the accessibility of a given locker. Furthermore, the lamp can be configured so that, in addition to indicating the accessibility of the locker, the user will also receive information about the opening the door of the locker, and the illuminated interior will make it easier to see its content. The role of lighting the inside of the locker is performed primarily by the lighting element mounted inside it. The door can also be provided with sensors, in the form of, for example, a camera or a device used to detect the load of the locker, thus informing about its accessibility and the possibility of accepting a new parcel. <CIT> discloses a door for lockers or cabinets with limited access, the door comprising a light.

The aim of the invention is the construction of door for lockers or cabinets with limited access, in particular post office boxes, which will ensure safe use of lockers or cabinets, and at the same time allow the users to easily identify the correct locker or cabinet or its parameters.

The invention relates to a door for lockers or cabinets with limited access, in particular post office boxes, as defined in claim <NUM>.

It is also expedient for the front wall of the body to have a size substantially corresponding to the size of the selected edge of the front panel.

Preferably, between the front panel and the rear panel there are plurality of bodies, assigned to each side of the front panel. It is appropriate when the rear panel is attached to the side walls.

Equally preferably, the body has two sided wall forming external recesses on which the front panel and the rear panel are supported, wherein the size of the through holes in the front panel and the rear panel substantially corresponds to the external dimension of the recess.

Preferably, the external walls of the recesses are provided with sealing elements.

It is particularly appropriate when the rear panel has a catch attached which is designed to cooperate with a lock of the locker.

It is also appropriate when the door has a ground wire attached to an element selected from the front panel, the side walls, and the rear panel.

Also preferably, the size of the rear panel is matched with the dimensions of the front panel.

It is also expedient for the front panel and side walls to be made of a single sheet of metal.

It is reasonable for the front panel to have side walls attached.

It is appropriate when the rear panel is provided with an eave extending beyond the plane of the front panel.

Equally preferably, the body has a lens in the front wall.

As used herein, a lighting element is understood as any element capable of emitting light or displaying information. These can be, in particular, LEDs, displays or monitors of various sizes and configurations.

The basic advantage of the invention is to ensure full safety of users when using lockers or cabinets. The use of the rear panel allows to protect the lighting element mounted in the door even against unintentional damage caused by the user of the lockers or cabinets. What's more important, however, the rear panel protects users especially against breakdown and short circuits, which is a typical hazard associated with the use of electrically powered devices. Protecting structural elements in the door, in particular elements accompanied by the flow of electricity, ensures safety during use and reduces the risk of failure. Furthermore, the presence of the rear panel improves the strength of the entire construction of the locker or cabinet door.

The construction in which the door of the locker or cabinet has the front panel, the rear panel, and the lighting element placed between is simple, and the manufacturing process is not complicated. This is in particular due to providing the body of the lighting element with external recesses, on the walls of which the front panel and rear panel are supported. Such design increases the rigidity of the entire locker or cabinet door.

In particular, when the size of the rear panel is matched with the dimensions of the front panel, production costs can be reduced. An additional benefit results from the use of a lens embedded in the body. Thanks to this, it is possible to magnify a small image generated inside the body. In particular, the lens can magnify the light emitted inside the body even by a single LED.

Ensuring a simple design of the locker door with a limited number of structural elements facilitates servicing and reduces the susceptibility to failure of the locker or cabinet door elements. Placing the lighting element in the body leads to the creation of a simple modular construction in which individual elements, including parts containing electrical components, can be easily replaced.

An equally important advantage of the solution is the mounting of a lighting element in each door of a locker or cabinet unit. Such units contain many lockers of various sizes, often lockers of the same dimensions are located close to each other. This often causes a problem with identifying the locker that the user is supposed to use. The use of lighting elements makes it much easier for the user to recognize the right locker or cabinet in the locker or cabinet unit. The right locker or cabinet can be marked by the lighting element displaying a particular colour, or the user can follow the lighting elements leading to the selected locker. Another advantage of placing lighting elements in the doors is the ability to display and inform about the failure of the device, its occupancy or the accessibility of individual lockers. Using a lighting element one can generate a lot of information for users.

Furthermore, the use of the eave extending beyond the plane of the front panel allows for effective drainage of water or accumulated moisture, and at the same time ensures the reliability of the locker's operation regardless of its location and weather conditions.
