Definitions

• the present invention relates to a damped, force-assisted hinge, particularly for use in vehicles and aircraft.
• Overhead bins especially in aircraft, are highly stressed components and present a technical challenge for aircraft cabin outfitters.
• the available cabin space must be used optimally, handling should be simple, and the opening and closing behavior must meet the requirements of passenger exchange.
• the following discussion focuses on overhead bins, which are typically designed as fixed containers on the cabin ceiling with a flap for opening and closing.
• the flap is attached to the bin by means of two hinges.
• a separate locking mechanism secures the flap, preventing luggage from falling out.
• Both the hinges and the locking mechanism must meet high safety standards to ensure safety even in cases of overloading, improper operation, and challenging flight attitudes. It is known to mechanically assist the opening movement of the flap after unlocking. It is also known to dampen this opening movement so that the flap does not spring open uncontrollably.
• the EP 0 894 933 A2 This describes a hinge with a device for assisting the opening movement and a device for simultaneously damping this opening movement.
• the components for this are compactly integrated into the hinge.
• the damping is designed so that the opening speed of the flap decreases as the opening angle increases.
• the opening movement is assisted by one or two pre-tensioned torsion springs.
• the EP 1 217 158 A2 This describes a hinge with a fixed and a movable hinge leaf, which share a hinge axis designed as a hollow axle.
• a torsion spring is arranged within the hollow axle to assist the opening movement.
• the writing DE 20 2007 014 471 U1 The figure shows a hinge for a luggage compartment with a torsion spring as the drive for the opening movement.
• the preload for the torsion spring is adjusted by rotating a component that is inserted into one end of the hollow axle. This component holds one end of the spring and has external teeth on a pin on the other side.
• a retaining ring is inserted into the hollow axle. The retaining ring engages the external teeth of the pin on the inside and locks into a corresponding internal tooth on the hollow axle. This defines the position of the component relative to the hollow axle.
• the US 2013/081228 A1 describes a swiveling hinge with fluid damping for luggage compartments.
• the object of the present invention is to further develop the state of the art, in particular to improve the handling and safety of luggage compartments in cars and airplanes.
• the following disclosure describes a hinge in a functional assembly.
• the hinge(s) On the luggage compartment lid, the hinge(s) is attached at the top, so the lid basically opens upwards against gravity.
• a hinge for the aforementioned applications as a luggage compartment generally comprises two hinge leaves, with the first hinge leaf having a bearing bushing.
• the second hinge leaf has a first and a spaced-apart second bearing bushing, which are arranged coaxially (aligned).
• the bearing bushing of the first hinge leaf is rotatably mounted between the bearing bushings of the second hinge leaf about a common hinge axis.
• the hinge comprises an axle tube that is non-rotatably connected to the bearing bushing of the first hinge leaf and rotatably mounted in the bearing bushings of the second hinge leaf.
• a torsion spring is located inside the axle tube, its first end being attached to the The axle tube is attached and connected at its second end to an adjustment element for the preload of the torsion spring.
• the hinge has a damping element for its pivoting movement, which is arranged in a rotationally secure manner in the first bearing bushing of the second hinge leaf and is connected to the axle tube on the other hand.
• the arrangement of the torsion spring, pawl, and ratchet wheel allows the locking action of the pawl to be ensured even without axial preload on the torsion spring.
• this hinge it is not necessary to anchor the torsion spring in the axle tube or on the adjusting element with axial tensile strength.
• Torsion springs made of spring steel are frequently pre-tensioned in the closing direction, meaning they are twisted in the direction of the coils, to achieve a desired restoring torque. This inevitably increases the number of coils in the torsion spring, which in turn leads to a decrease in the spring's diameter due to the constant wire length, while simultaneously increasing its length. This pre-tensioned spring could deflect laterally within the axle tube due to its reduced outer diameter. However, if the torsion spring is pre-tensioned axially, the axial tension decreases with increasing torsion.
• the spring is twisted in the opening direction against the winding direction to ensure the torque required during operation.
• the spring becomes shorter and increases in diameter. This can be compensated for by appropriately dimensioning the axle tube.
• the advantage is that the spring ends can be arranged in corresponding receiving pockets or openings in the adjusting element or in the axle tube with axial longitudinal play, and no pressure is exerted in the axial direction.
• the locking action of the pawl can be supported by a spring arranged between the second bearing bushing and the pawl in such a way that it counteracts a pivoting movement of the pawl out of engagement with the ratchet wheel.
• a compression spring is preferred.
• the aforementioned detent element for adjusting the torque of the torsion spring essentially comprises a ratchet wheel and a pawl.
• detent elements are known in many designs in the prior art.
• the ratchet wheel has external teeth on its outer contour, typically with one steep and one flat tooth flank, similar to a sawtooth.
• the tip of the pawl can slide over the flat flank when rotating forward, while when attempting to rotate backward, it engages the steep flank, forming a positive connection and preventing rotation.
• the pawl tip is held against the locking piece perpendicular to its direction of movement by a force-fit connection (spring force).
• spring force Depending on the geometric design of the tooth flanks, it is possible to disengage the pawl from the ratchet wheel by applying a force against the retaining spring. If—in an idealized scenario—the locking tooth flank has a perfectly radial orientation, then, in addition to the force of the retaining spring, the friction of the contact surfaces between the pawl and the tooth flank must also be overcome. This makes it clear that—in the present arrangement—the surface pressure between the ratchet wheel and the pawl caused by spring torsion plays a role when the pawl is to be disengaged. Therefore, it is advantageous to reduce this surface pressure by rotating the ratchet wheel slightly against the locking direction, thus relieving the pressure on the pawl.
• This relief step is particularly necessary when the inhibiting tooth flank is inclined in the locking direction and the pawl thus rests in a kind of pocket of the gear rim.
• the stop element has a stop disc that rotates with the adjusting element and has a limiter in the form of a radially outwardly projecting circular sector, and uses a stop pin that is fixedly mounted in the second bearing bushing.
• the limiter in conjunction with the stop pin, thus prevents the torsion spring from being pre-tensioned beyond the range defined by the two stops.
• the angular range ⁇ of the limiter is chosen such that the first end of the circular sector forms the stop for the target torque in the "open” state of the hinge.
• the second end of the circular sector forms the stop for over-rotation protection of the torsion spring.
• the adjustment of the setting element can be carried out according to the following pattern: The individual components, such as in Figure 1 The components shown are assembled into a hinge in the "open” position. The basic spring tension is set so that the resulting torque of the torsion spring corresponds to the specified torque in the "open” or “held open” position. The detent element is then connected to the bearing bushing with a torque-locking connection, and the pawl is engaged. The orientation of the stop disc is selected so that a locking pin, extending through the bearing bushing into the limiter's operating range, is positioned near or at the first stop of the circular ring sector. This setup is also referred to as the factory setting.
• the torsion spring can rotate back to its factory setting at the first stop.
• the second stop is reached after a defined number of clicks when the locking element is rotated forward. This prevents the user from over-rotating the torsion spring and thus damaging or destroying it.
• the torsion spring With each click, the torsion spring is pre-tensioned more, increasing the return torque that helps open the luggage compartment door. This allows a single hinge to be used for luggage compartment doors of varying weights, within the limits determined by the spring's torsion.
• the number of clicks serves as a guide for the adjuster, indicating how to adjust the spring. to the extent that he has already pre-tensioned the hinge. Alternatively, he can use a torque wrench, which is inserted into the inner grip for the tool on the locking element.
• This adjustment guide is an example, but not the only possible one. However, a professional can extract from it the objectives and a procedural logic that allows them to achieve the same result through an alternative sequence.
• the stop disc can be manufactured as an integral part of the adjusting element.
• the adjusting element can preferably be produced as an injection-molded plastic part. Additives such as fibers can be added to increase strength.
• the ratchet wheel can also be manufactured as an integral part of the adjusting element.
• the damping element can be designed so that the damping decreases as the hinge opens.
• the hinge is pre-tensioned in the "open" position. Therefore, when the luggage compartment lid is closed, the torsion spring is tensioned even further.
• This design is chosen to prevent partially open or partially open lids in everyday use. Conversely, this also means that a (just barely closed) luggage compartment lid experiences the greatest torque immediately after unlocking; it could therefore spring open unexpectedly. For this reason, the damping element compensates for the torque most effectively immediately after the lid is unlocked.
• the decreasing damping ensures that the lid is damped less as the opening angle increases. Ideally, the characteristic curve is adjusted so that the opening speed is essentially constant.
• the housing of the second bearing bushing can be provided with a release opening through which the pawl can be unlocked using an inserted tool.
• This design is inconspicuous yet easily accessible. As described above, this usually requires a relief mechanism for the pawl.
• a luggage compartment for an aircraft or vehicle therefore comprises a container for holding items with an opening that can be closed by a flap.
• the connection between the container and the flap is realized by at least two hinges as described above.
• the adjustment mechanism with audible clicks then allows for easy adjustment of both hinges to the same opening and closing characteristics.
• Figure 1 shows the exploded view of the components of a hinge according to this description.
• Reference numbers 100 and 200 denote the first and second hinge leaf, respectively.
