ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a connection fitting for the detachable connection of two parts, preferably furniture parts, consisting of a cup-shaped casing which can be placed into a channel of the first part, in which casing a bolt with a tenon which protrudes over the first part is pivoted which bolt can be inserted in a borehole of the other part and locked in place in it by a turn, and of a radial actuating lever connected to the bolt which lever penetrates a hole in the casing.
In a connection fitting of this type known from DE 44 37 273 C2, in accordance with a first embodiment the radial actuating lever is permanently connected to the bolt so that it protrudes over the casing even in the locked state and has an unappealing and annoying appearance. If the actuating lever were to be made shorter to allow it to be countersunk in the casing in the locked state, it could only be opened by hand with great difficulty.
In accordance with a second embodiment of the known connection fitting, it is provided that in the region of the casing hole, the bolt is provided with a serrated section and the actuating lever with a ring with a corresponding inside serration which encloses the bolt in such a way that by an axial movement of the actuating lever in the channel said actuating lever can engage and disengage with the serrated section of the bolt. While this embodiment allows a substantial countersinking of the actuating lever in the locked state of the bolt in the casing hole, it is, however, relatively complicated to engage the actuating lever in an interlocking manner with the bolt by an axial movement and then to release it again from the bolt, with the actuating lever not being able to cover the hole completely in the locked state either due to the axial movement capability.
SUMMARY OF THE INVENTION
It is the object of the invention to provide a connection fitting of the type first described which can be mounted easily by hand alone, with the actuating lever not protruding over the casing in the mounted state of the connection fitting and with the connection fitting providing a compact and appealing appearance in the mounted state.
This object is solved in accordance with the invention by a connection fitting with the features decribed herein.
In the connection fitting in accordance with the invention, the actuating lever which can be actuated by hand can be easily interlocked with the bolt by its being pressed into an inserted position. When the bolt is turned into the locked position by the actuating lever, it can be pulled out, thereby the interlocking connection with bolt released and the bolt pivoted into a position in which it can be held in a countersunk manner in the casing.
Appropriately, in the inserted position, the actuating lever engages a radial or lateral opening or recess of the bolt with an extension.
In accordance with a preferred embodiment, it is provided that the bolt is provided with a radial pillar block with lateral tenons parallel to the bolt onto which the legs bent into a fork-like U shape of one side of the actuating lever can be hooked and that the actuating lever engages the recess with an extension protruding over the legs. In this embodiment, the actuating lever is interlocked with the bolt by its engaging the recess with its front tenon-shaped end and being held by the legs bent in a U shape with a region positioned at a the distance of the tenons on the bolt so that the lever engages the bolt via a two-point support and a good interlock is ensured. If the lever is pulled out of its interlock position, the tenons of the pillar block form, as it were, the swivel axes for the actuating lever to allow this to be swivelled into its position countersunk into the casing.
Appropriately, the actuating lever consists of a substantially rectangular sheet blank from whose one narrow side legs which protrude over this at the side are bent back in a U shape in such a way that these are protruded over in the bent state by a bar located between them. The protruding bar forms the tenon which engages the channel of the bolt.
Appropriately, the casing hole corresponds to the shape of the actuating lever so that the actuating lever can be pivoted in its withdrawn state around the tenons of the pillar block in such a way that it covers the hole.
The actuating lever can be insertable into the hole in such a way that its outside is flush with the plane outside of the casing.
Appropriately, the bolt is provided with a radial protrusion which forms a stop for a casing-integral abutment and limits the turn of the bolt.
To lock the tenon which extends the length of the bolt in a borehole of the other part, the tenon can, for example, be provided with a thread. Appropriately, however, the tenon is connected eccentrically to the front side of the bolt in the manner known from DE 44 37 273 C2, with a washer provided with a cutting bar being fixed on the eccentric shaft part as the locking piece. The washer can additionally be provided with at least one cutting thread. Furthermore, the casing can be provided with a tenon-like extension of the type known from DE 44 37 273 C2 which is provided with an eccentric borehole in which the bolt is supported.
