DETAILED DESCRIPTION OF THE INVENTION

(7) The object of the invention is a device for transferring elements through a surface, such that the elements housed in a container cross through the surface.

(8) The device comprises a frame (1) fastened in an opening (2) of the surface to be crossed through, such that the container (3) is joined to the frame (1) by means of two pairs of rods (4, 5), one on each side of the container (3). In the container of the device object of the invention, each pair of rods (4, 5) is made up of a first rod (4) and a second rod (5), the first rod (4) and the second rod (5) being parallel to each other.

(9) The container (3) of the device object of the invention has the shape of a rectangular prism comprising a bottom, two side walls (17), a front wall (18) and a back wall. The container (3) passes through the frame (1) fastened in the opening (2) of the surface to be crossed through

(10) Each rod (4, 5) is fastened to the frame (1) by means of a bolt (6) on one end of each rod (4, 5) and to the container (3) by means of another bolt (7) on the opposite end of the rod (4, 5) such that the rods (4, 5) have the ability to rotate resting on the bolts (6, 7).

(11) Each pair of rods (4, 5) forms a deformable parallelogram, such that the position of the rods (4, 5) enables the movement of the container (3) through the frame (1), meaning the rods (4, 5) rotate around the bolt (6) joining the rod (4, 5) to the frame (1) and in the rotation they make it so the container (3), starting from a first position on one side of the surface, performs a translational movement by being slightly lifted as it crosses through the frame (1) and being lowered again in a second position, which is symmetrical to the first position with respect to the surface.

(12) In order to move the container (3), starting from one position, it is necessary to rotate the rods (4, 5) in one direction, for which reason they need to receive a force, which arrives to them through a first push rod (8) fastened to the first rod (4) perpendicular to it, or through a second push rod (9) fastened to the second rod (5) perpendicular to it.

(13) Thus, given that in the preferred embodiment of the invention there is a pair of rods (4, 5) on each side of the container (3), the device object of the invention comprises two first push rods (8) which are joined by a first handle (10) on which an ascending or descending push must be performed in order to move the container (3); the device object of the invention further comprises two second push rods (9), which are joined by a second handle (11), on which, just as occurs with the first handle (10), an ascending or descending push must be performed in order to move the container (3) from the other side of the surface.

(14) Between the frame (1) and the container (3) there is a space in order to enable the movement of the parallel rods (4, 5), and furthermore, the front wall (18) and the back wall of the container (3) have lateral slots (12) to enable the passage of the push rods (8, 9). With this configuration, the container (3) and the parallel rods (4, 5) pass in a manner that is fitted against the geometry of the frame (1).

(15) The first push rods (8) and the second push rods (9), in the preferred embodiment of the invention, are located at an equal distance from the bolts (7), such that they follow the same alignment when the parallel rods (4, 5) are vertical and have parallel alignments in any other location.

(16) The frame (1) is fastened in the opening (2) of the surface to be crossed through by means of six through screws (13).

(17) As a security mechanism, the device object of the invention comprises a chain (14) joined to the first handle (10), such that said chain (14) is configured to be fastened to an upper forked bracket (15) or lower forked bracket (16), locking the position of the container (3).
