• the first guide is, or defines, for example, a first path of motion or first guide path along which the actuating element can be moved relative to the base element.
• the first guide defines a first direction of movement, corresponding in particular to the first path of motion or the first guide path, along which the actuating element can be moved relative to the base element.

• the first guide is straight and runs along the first straight line. It is preferably provided that, in the installed position of the hinge, the first guide, and thus the first path of movement or the first guide path, and thus, for example, the first direction of movement, runs in a vertical direction.
• the hinge assumes its installed position when the device containing the hinge is fully manufactured and when the device is in its intended operating position. For example, in the operating position, the device rests on a plane that is at least substantially horizontal.

• the spring Since the actuating element is coupled to the spring and guided along the first guide of the base element, and thus movable relative to the base element, the spring is tensioned and relaxed by moving the actuating element along the first guide and thus relative to the base element. In other words, if the actuating element is moved back and forth along the first guide and relative to the base element, the spring is thereby tensioned and relaxed, particularly alternately. Put another way, if, for example, the actuating element is moved in a first direction along the first guide relative to the base element, the spring is tensioned. If, for example, the actuating element is then moved in a second direction opposite to the first along the first guide relative to the base element, the spring is at least partially relaxed.
• the spring is designed as a tension spring, which, for example, is guided—that is, its length is increased and thus tensioned—when the actuating element is moved along the first guide in the first direction. If, for example, the actuating element is then pushed in the second direction along the first guide, the spring is thereby shortened in length, i.e., its length is reduced and it is at least partially relaxed.

• the third pivot axis is parallel to the first pivot axis, parallel to the second pivot axis, and parallel to the axis of rotation.
• the transmission element can be driven by the hinge arm via the lever element and thereby rotated around the axis of rotation relative to the base element. This allows the actuating element to be driven by the transmission element and thus moved along the guide relative to the base element, tensioning and releasing the spring.
• the transmission element is driven via the lever element and thereby rotated around the axis of rotation in a first direction relative to the base element.
• the first pivot direction and the first direction of rotation are, for example, in the same direction in a plane of motion perpendicular to both the first pivot axis and the axis of rotation. Because the transmission element is rotated around the axis of rotation in the first direction relative to the base element, the actuating element is driven by the transmission element and thus moved, for example, along the guide in the first direction relative to the base element. This tensions the spring.
• the hinge arm also referred to as a swivel arm
• the transmission element is thereby driven by the hinge arm via the lever element and thus turned around the axis of rotation in one of the first
• the second direction of rotation is opposite to the first, and is rotated relative to the base element.
• the second pivoting direction and the second direction of rotation are, in particular, related to the plane of motion, i.e., they are in the same direction within the plane of motion.
• the actuating element is driven by the transmission element and thus moved along the first guide in the second direction relative to the base element.
• This for example, at least partially relaxes the spring.
• the tensioning and relaxation of the spring means the following:
• the actuating element can be moved along the first guide relative to the base element between at least one first actuation position and at least one second actuation position.
• the actuating element can be moved from the first actuation position to the second actuation position by being moved or pushed along the first guide in the first direction.
• the actuating element can be moved from the second actuation position to the first actuation position while being moved or pushed along the first guide in the second direction.
• the spring In the second actuation position, the spring is under greater tension compared to the first actuation position. Conversely, the spring is under less tension in the first actuation position compared to the second. In the first actuation position, the spring may be completely relaxed, or it may be under tension, but less so than in the second.
• the spring provides a spring force, at least in the second actuation position, which acts, for example, via the actuating element, the transmission element, and the lever element, on the hinge arm and, for example, on the door of the device via the hinge arm.
• the hinge arm can be pivoted or turned about the first pivot axis in the first pivot direction relative to the base element against the spring force.
• the hinge arm can be turned relative to the base element about the first pivot axis between at least one first pivot position and at least one second pivot position.
• the hinge arm can be turned from the first pivot position into the second
• the hinge arm can be pivoted or turned into its pivot position by pivoting or turning it around the first pivot axis relative to the base element in the first pivot direction.
• the hinge arm can be pivoted or turned from the second pivot position into the first pivot position by pivoting or turning it around the first pivot axis relative to the base element in the second pivot direction.

• the door can be closed, i.e., pivoted or turned from the open position to the closed position, especially relative to the device body and the base element, by pivoting or turning the hinge arm from the second pivot position to the first pivot position about the first pivot axis relative to the base element.
• the hinge arm when, for example, the door is opened, the hinge arm is pivoted around the first pivot axis relative to the base element in the first pivot direction, thus pivoting or swiveling from the first pivot position to the second pivot position.
• the hinge arm When the door is closed, the hinge arm is pivoted or turned around the first pivot axis relative to the base element in the second pivot direction, thus pivoting or turning from the second pivot position to the first pivot position.
• the spring is tensioned when the door is opened, so that, for example, the spring force opposes the opening of the door. This is particularly advantageous because it prevents excessively rapid and/or surprising and/or automatic opening of the door, i.e., opening caused by the weight of the door.

• the front panels can have different weights, and some can be very high, depending on the material from which they are made.
• the hinge according to the invention can be used particularly advantageously for doors with high weights, especially because the transmission element and the lever element, via which the transmission element is coupled to the hinge arm, allow for advantageous gear ratios between the hinge arm and the spring.
• the hinge according to the invention can be adapted to different door weights particularly easily and therefore in a time- and cost-effective manner, so that the hinge has a particularly wide and therefore flexible range of use, which is also referred to as the application range.
• actuating element is coupled to the spring, for example to one end of the spring, and since the actuating element is displaceable along the first guide, a spring guide is created by the actuating element and the first guide, by means of which the spring is to be guided, i.e., guided, especially when the spring is tensioned and relaxed.
