Description

DRAWINGS

[0012] Embodiments will be illustrated by way of example in the drawings and explained in the description below.

[0013] FIG. 1 illustrates a perspective view of a flap system, in accordance with embodiments.

[0014] FIG. 2 illustrates a perspective view of a closure rail of the flap system of FIG. 1.

[0015] FIG. 3 illustrates a perspective view of movement of the closure rail of the flap system of FIG. 1 to an upward position.

DESCRIPTION

[0016] As illustrated in FIGS. 1-3, a flap system 1 in accordance with embodiments includes a flap 2 having a closure rail 9 with keyhole-shaped recesses 10 having a large and a combined small diameter. The connection to the drive is carried out via a rail 6, which has a plurality of cylindrical openings 5 which enables a complete force absorption of the drive forces in an active direction of the flap system.

[0017] The flap 2 has an end region 3 with a tongue to which a shaft 4 is fitted perpendicularly thereto (the tongue), but in extension of the flap axis. The shaft 4 comprises two regions: a bearing region 7 and a closure region 8. The bearing region 8 has a diameter which corresponds structurally and operationally to the cylindrical opening 5 so that the shaft 4 may be readily introduced.

[0018] The assembly is explained in FIGS. 2 and 3. After the shaft(s) 4 has/have been introduced into the openings 5 of the rails 6, the bearing region 7 of each shaft 4 is located inside the rail 6, the closure region 8 protrudes beyond the rail 6. The closure rail 9 is placed parallel with the surface of the rail 6. To this end, in the keyhole-shaped recess 10, the region having a large diameter is used so that the closure region 8 of the shaft 4 may also be inserted through the closure rail 9. Since the closure region 8 of the shaft 4 comprises a first portion 4′ having a small diameter and a second portion 4″ having a large diameter, the closure rails 6 may lock the shaft 4. The length of the first portion 4′ is determined in this instance by the thickness of the closure rail 9. To this end, the closure rail 9 is moved, from FIG. 2 to FIG. 3, in an upward direction in accordance with the arrow and the keyhole-shaped recess is consequently displaced into the region of the small diameter.

[0019] The closure of the connection is carried out perpendicularly to the active direction of the drive.

[0020] The term “coupled,” “attached,” or “connected” may be used herein to refer to any type of relationship, direct or indirect, between the components in question, and may apply to electrical, mechanical, fluid, optical, electromagnetic, electromechanical or other connections. In addition, the terms “first,” “second, etc. are used herein only to facilitate discussion, and carry no particular temporal or chronological significance unless otherwise indicated.

[0021] This written description uses examples to disclose the invention, including the preferred embodiments, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of embodiments is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims. Aspects from the various embodiments described, as well as other known equivalents for each such aspects, may be mixed and matched by one of ordinary skill in the art to construct additional embodiments and techniques in accordance with principles of this application.
