Abstract

A folding lock (1) comprising a lock body (2) accommodating a closing unit (3) and a folding bracket which comprises angled bracket segments (4a, 4b) formed from a metal or a metal alloy, wherein a first terminal bracket segment (4a) is attached to a End region of this bracket segment (4a) is fixedly connected to the lock body (2) and the end portion has a passage opening (5) which is designed for carrying out the closing unit (3) in the lock body (2), characterized in that the first terminal bracket segment (4a) and the lock body (2) are formed separately and in that on the first end bracket segment (4a) formed of a plastic sheath (6) is mounted, wherein the sheath (6) adapted either for connection to the lock body (2) or integrally formed with the lock body (2).

Description

The The present invention relates to a folding lock with a lock body and a folding handle and in particular, it relates to a folding lock with a lock body and a folding handle, where a first terminal bale segment firmly with the lock body connected is.

conventional Folding for a Bicycle have a locking unit housing a lock body and a folding handle on, the hinged, made of a metal or comprises a metal alloy formed bracket segments, of which a first terminal bale segment at an end portion of this bracket segment with the lock body is firmly connected by the first terminal bracket segment integral with the lock body is trained. A disadvantage of conventional folding locks is in that for a safety Rupture attempts sufficiently robust design much metal needed becomes.

The Object of the present invention is therefore in the above mentioned disadvantage of conventional Folding to overcome and an improved design with the same or increased security level to reach.

These Task becomes with a folding lock with a a closing unit accommodating lock body and a folding handle, the hinged, made of a metal or a metal alloy formed strap segments comprising a first terminal bale segment at an end portion of this bracket segment firmly with the lock body is connected and the end portion has a passage opening, which is used to carry out the Closing drive unit in the lock body designed, solved, that the first terminal bale segment and the lock body separately are formed and that at the first terminal bracket segment one of a plastic formed sheath is attached, wherein the sheath either for connection to the lock body adapted or in one piece with the lock body is trained. The advantage of this embodiment is that with the same use of metals or metal alloys stability can be increased can or that for a consistent stability the required use of metals or metal alloys can be reduced. Another advantage is that through the sheath of the strap segments avoided with plastic any impact damage to the bicycle frame can be.

Prefers In the case of the folding lock, the lock body is formed from a plastic, which additionally saves metal with the same stability the stability can be increased with the same metal insert.

When It has proven advantageous if the locking unit a formed of a metal or a metal alloy housing with an outer collar on a key page wherein the collar for abutment with the end portion of the first terminal strap segment is adjusted. An advantage of this embodiment is that at the connecting surfaces, which are particularly stressed in Aufbruchversuchen, metal or Metal alloys are present, whereby the stability is increased.

For such Folding lock it is particularly favorable if the case on one of the key page across from lying locking side has a latch opening, which for receiving and for lateral introduction one at a second terminal bale segment arranged bolt head is configured. An advantage is that with the bolt head a rotatability of the second terminal bracket segment across from the lock body is reached.

Farther can the lock body have a semicircular locking element on the locking side, in the locked state, a movement of the bolt head from the Bar opening prevented. Preferably, the lock body on the locking side an end plate with a guide and an opening for the Bolt head on, whereby the stability of the lock is increased.

Especially Preferably, the end plate has mounting holes in the screws or pins for attaching the end plate to the lock body are. In this way, the end plate can be safer against break-in attempts with the lock body get connected.

in the The invention will be described below with reference to a drawing Embodiment explained in more detail; it demonstrate:

1 a schematic representation of a first terminal bracket segment for a folding lock according to the present invention,

2 a further schematic representation of the first terminal strap segment in a different perspective,

3 an exploded view of a lock body with a closing unit and an end plate,

4 an exploded view of Closing unit and

5 a schematic representation of the folding lock.

1 and 2 show schematic representations of a first terminal bracket segment 4a for a folding lock 1 according to the present invention. The first terminal bracket segment 4a has at one end a passage opening 5 on and is stuck with a lock body 2 connected. At the first terminal bracket segment 4a is a sheath 6 attached to the connection to the lock body 2 is adjusted.

3 shows an exploded view of the lock body 2 with a closing unit 3 and an end plate 11 , The lead-through opening 5 is to carry out the closing unit 3 in the lock body 2 configured, wherein the locking unit 3 a housing 7 includes, on the key side, an outer collar 8th having, for abutment with the end portion of the first terminal strap segment 4a is adjusted. On one of the key side opposite latch side, the housing 7 a latch opening 9 for a bolt head 10 on, the side by means of a locking element 15 can be closed. In addition, on the bar side an end plate 11 that a leadership 12 and an opening 13 for the bolt head, with pins 16 through mounting holes 14 on the lock body 2 be attached.

4 shows an exploded view of the locking unit 3 , A lock cylinder 17 is in the case 3 arranged so that a key 18 can be inserted laterally. Preferably, the housing 7 and the lock cylinder 17 formed from a metal or a metal alloy.

5 shows a schematic overview of the folding lock 1 , The bolt head 10 at the second terminal latch segment is located in the latch opening 9 , the laterally in the locked state by the locking element 15 closed is.
