Hinged closure assembly for a portable telephone

0001The invention relates to a rotating shutter unit, in particular a rotating shutter unit for portable telephones.

0002The principle of a so-called snap-lock unit, in which a locking by snapping a snap hook is achieved in a corresponding closure member, is known. The lock is generally by a spring force causes. By applying a corresponding counterforce the lock is released again, the release force is exerted on an extension of the snap hook.

0003A disadvantage of the known closure units is their constructive Effort and space requirements, the previously use in portable telephones is not allowed.

0004The invention is therefore based on the object, a suitable Shutter unit for portable telephones, and a corresponding Battery unit and such a portable telephone to create, said with such a shutter unit, for example, a battery unit to a casing of a portable phone can be fastened.

0005The object is achieved by the features of claims 1, 3 and 5 dissolved. Preferred embodiments of the invention are the subject of the subclaims.

0006In a closure according to the invention for a portable telephone, the locking by the engagement of a Snap-in hook in a closure member under the influence of a spring force causes the snap hook is fixed to a rotation axis the closure connected.

0007Preferably, the closure unit has a touch surface, which is fixedly connected to the rotary object and the Snap fit an angle> 0 ° forms, so that a one-piece Snap hook assembly yields. In other words, the Snap hook plane formed by the snap hook and the axis is of the touch surface and the rotational axis Tastflächenebene formed differently.

0008Preferably, the closure according to the invention in a battery unit a portable telephone used with the battery unit using one or more fasteners to the housing of the portable telephone is attached.

0009Preferably, the tactile surface for releasing the lock is to adapted to the contour of the housing of the battery unit.

0010In use of the closure in a portable telephone the closure member is arranged on the housing of the portable telephone, during the snap-action hooks, the tactile surface, the axis of rotation and generating the spring force spring to the housing the Batterleeinheit are arranged.

0011A preferred embodiment of the invention will be explained with reference to the drawings.<sl><li>Fig. 1 shows a cross section through an inventive closure,</li><li>FIGS. 2a and Fig. 2b respectively show a perspective front and Rear view of the snap hook assembly, and</li><li>3 shows a perspective view of the back of a portable phone with a battery pack.</li></sl>

0012Fig. 1 shows a cross sectional view through an inventive Snap hook fastener 1 consisting of a snap hook assembly 2, the locked by a closure member. 6 The Snap hook unit 2 includes the actual snap hooks 3, which is fixedly connected with a rotation axis. 4 The Snap hook unit 2 further comprises a touch surface 5, which with the snap hooks 3 at an angle> 0 ° about the axis of rotation 5 is firmly connected, that is, the touch pad 5, the Snap hook 3 and the rotational axis form the contiguous piece snap hook unit 2. The contour of the Touch surface 5 adapts to the shape of the housing 8 a battery unit a portable phone on. The above-mentioned Locking member 6 engages for locking the closure 1 in the snap hooks 3 a. The necessary holding force is A spring 7 is generated. By generating a pressure on the Touch surface 5 is of the snap hook 3 from its locking position rotate and open the lock. 1 If no pressure generated on the touch surface 5, as is represented by the spring 7 of the Snap hook 3 is rotated again in the locking position. The Closure member 6, which also in cross-section in a hook shape can be formed, is preferred in the illustrated Embodiment, part of the housing 9 of a portable Phone.

0013Fig. 2a shows a front view of the snap hook unit 2 with the axis of rotation 4 and the firmly bonded touch surface . 5

0014FIG. 2b shows a rear view of the snap hook unit 2 with the rotational axis 4 as well as the associated snap hook 3 and the partially sighted tactile surface. 5

0015Fig. 3 shows a perspective view of a portable telephone consisting of a housing 9 and, arranged thereon Battery housing 8. The housing 8 of the battery pack is the Closure 1 of the invention disposed It can be seen, that the touch surface 5 of the closure 1 to the contour of the Housing 8 of the battery unit is adapted. Thereby, it is possible to arrange in a small space a snap fit closure. 1
