    [0016] [0016] In a preferred embodiment, only the second door assembly comprises a frame lock for locking both the first and the second door assembly to the casing. Brief description of drawings
    [0017] [0017] The invention is now described, by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a perspective overall view of a letterbox unit according to the invention, N comprising two columns of compartments and corresponding door assemblies, & Lo S each with nine compartments and corresponding compartment doors, 3 Figs. 2a-d show the left door assembly of the letterbox unit of Fig. 1 in plan view, E side view, perspective view, and top view, respectively,
    [0018] [0018] In the following, a detailed description of a letterbox unit according to the invention will be given with reference to the drawings. When references are made to directions, such as “left” and “bottom”, these refer to what is shown in the figures for better understanding of the invention and are not limiting to the scope of protection.
    [0019] [0019] In Fig 1, a letterbox unit, generally designated 1, is shown. The letterbox unit 1 comprises a casing 10 divided into a plurality of letterbox compartments 12 arranged in two columns, separated by a central wall 14. The casing 10 has an open forward-facing side 10a arranged to give access to the letterbox compartments 12. On the other sides, the casing 10 comprises a left side wall 10b, a right side wall 10c, a top wall 10d, a bottom 10e, and a back wall 10f, forming a box-like structure.
    [0020] [0020] Two door assemblies 20, 30 are arranged to, in closed position, cover the open forward-facing side 10a of the letterbox unit 1. A left door assembly 20 covers the left column of letterbox compartments 12 and a right door assembly 30 covers the right column of letterbox compartments 12. Each of the door assemblies 20, 30 comprises a plurality of compartment doors 22, 32 arranged in a column, wherein each compartment door is arranged to, in closed position, cover S a corresponding letterbox compartment 12. The compartment doors 22, 32 are O pivotably arranged so that they can be opened and closed, as will be described 3 below. Each of the compartment doors 22, 32 is provided with a compartment lock I 22a (not shown), 32a.
    [0022] [0022] All parts of the letterbox unit described above are preferably made of steel.
    [0023] [0023] Turning now to Figs. 2a-d, showing the left door assembly 20 from different views, the left door assembly comprises a single hinge, pivotally connecting the door assembly 20 at the left edge of the open forward-facing side of the casing 10, i.e., adjacent to the left side wall 10b thereof, see Fig. 1. The hinge comprises a single rod 26, preferably a steel rod, extending from the top wall 10d to the bottom 10e of the casing 10, wherein the rod 26 is kept in place by being inserted in a hole in the top wall 10d and the bottom 10e, respectively.
    [0024] [0024] Each of the compartment doors 22 is pivotably journaled on the rod 26, this is for example shown in Fig. 2a. In the preferred embodiment, this is achieved by providing a vertical through hole between the upper and lower corner of a S vertical side of each of the compartment doors 22, and the rod 26 extends through N these holes.
    [0026] [0026] The right door assembly 30 is shown in Figs. 3a-d. This is essentially a mirror image of the left door assembly 20 and comprises a single hinge, pivotally connecting the door assembly 30 at the right edge of the open forward-facing side of the casing 10, i.e., adjacent to the right side wall 10c thereof, see Fig. 1. The hinge comprises a single rod 36 extending from the top wall 10d to the bottom 10e of the casing 10, wherein the rod 36 is kept in place by being inserted in a hole in the top wall 10d and the bottom 10e, respectively.
    [0027] [0027] Each of the compartment doors 32 is pivotably journaled on the rod 36 in the same way as the compartment doors 22 of the left door assembly 20.
    [0028] [0028] The frame 34 is pivotably journaled on the rod 36. As can be seen from Fig. 3c, the frame 34 comprises three straight sections lining the compartment doors 32: an upper horizontal section 34a above the compartment doors, a vertical section 34b to the left of the compartment doors, and a lower horizontal section 34c below the compartment doors, together forming the frame. The frame 34 is provided with a door assembly lock 30a arranged on the vertical section 34b. The right frame 34 is journaled to the rod 36 in the same way as the left frame 24 so that the compartment doors 32 and the frame 36 are separately arranged on the same single hinge in the form of the rod 36.
    [0030] [0030] When a tenant or other person is to retrieve the mail stored in the compartment 12, he or she unlocks the compartment door 22, 32 by means of the compartment lock 22a, 32a and opens the compartment door, thereby having access to the compartment 12 behind this door. After having retrieved the mail, the compartment door 22, 32 is locked.
    [0031] [0031] A perspective view of a second embodiment of a letterbox unit according to the invention is shown in Fig. 4. This comprises two columns of compartments 12, but each column comprises only two vertically spaced apart compartments. In all other aspects, this letterbox unit is designed in the same way as the one shown in Fig. 1.
    [0032] [0032] Preferred embodiments of a letterbox unit according to the invention have been described. It will be realized that these may be varied within the scope of the appended claims without departing from the inventive idea. Thus, the letterbox unit has been described with a casing, but it is realized that the door assembly can be arranged in front of a recess in a wall or the like, acting as a space for the letterbox compartments.
    [0033] [0033] Letterbox units with two columns of compartments have been shown and described. It will be realized that the inventive idea is not limited to this. Thus, a letterbox unit with just a single column of compartments falls within the scope of the invention, in which case the single door assembly is provided with a main lock for locking and unlocking the single door. Also, more than two columns of S compartments may be provided, in which case each pair of columns forms a unit
