Description

The invention relates to a lock cylinder having a housing or housing part of a lock cylinder, comprising a housing cavity open to an end face of the housing or the housing part housing wall for an actuating shaft whose outer side runs along a profile cross-sectional contour, for insertion into a profile cross-sectional contour adapted insertion opening, for example. a Beschlagschildes, a rosette or a tubular frame or the like, with a running in the outside at least partially in the circumferential direction around the bearing cavity groove for the discharge of moisture.

The DE 102 19 901 describes a lock cylinder in which notches are provided in the apex region of the cylinder portion of the housing, with which the housing can tilt in a violent opening attempt at the opening of the lock case.

The DE 88 09 407 describes a lock for a trunk of a motor vehicle, wherein the housing of the round cylinder has a water gutter, which is immediately adjacent to the opening of the storage cavity for the cylinder core and which is to lie below a drip edge, so that dripping from the drip edge water through the channel down can be derived.

The US 4,671,090 describes a round cylinder with a Wasserabführrinne, which is immediately adjacent to the front side of the housing.

The EP 0 588 209 A1 describes a knob cylinder having a lock housing with a round portion and a flange portion which can be inserted into an insertion opening of a fitting plate.

From the DE 41 06 709 A1 a lock cylinder is known. The lock cylinder described therein has a housing which forms a central part, which can be combined with different end-side housing parts. The housing or the housing parts have an open to the front side of the housing or the housing part storage cavity in which an actuating shaft inserted. This actuating shaft is usually referred to as a cylinder core and carries in core holes tumbler pins that cooperate with stuck in housing bores, spring-loaded tumbler pins. The cylinder core has a keyway in which a matching key can be inserted, wherein the tumbler pins are sorted such that the cylinder core can be rotated relative to the housing. He then acts as an actuating shaft to rotate by turning the key, a closing member with which a mortise lock can be opened or closed.

An inventive lock cylinder has a bearing portion with a cross section having a circular area and an adjoining flange portion with an elongated contour. In the bearing section of the cylinder core or the actuating shaft is mounted. The housing tumbler pins or otherwise mechanical or electromechanically acting tumbler elements are seated in the flange section. The profile cross-sectional contour of such profile cylinder is standardized. On a door leaf to be fastened Beschlagschilder, rosettes, diaphragm plates or pipe openings of tubular frame have a profile opening, which is adapted to the profile cross-sectional contour of the bearing portion, so that the housing of the lock cylinder can be inserted into such a profile opening of the fitting plate. Between the housing outer wall of the lock cylinder and the opening edge of the insertion remains very narrow gap through which water can enter as a result of capillary action. This happens especially when such lock cylinders are used on doors in which at least one door side is exposed to the weather, for example. Garage doors, front doors or the like, so moisture can pass through the gap between the outside of the housing and inside the profile opening of the rainfall by capillary action Enter fitting plate. This capillary action occurs on lock cylinders, and on fully open doors even on both sides. The water passing through the joint into the area at the back of the fitting plate, the escutcheon or into a tubular frame can penetrate into the bearing cavity for the actuating shaft and lead to corrosion there or to icing in winter. Moreover, in an electronic cylinder, the water entering there may disturb or damage the function of the electronic components.

The invention is therefore based on the object of specifying measures with which this moisture ingress can be reduced.

The object is achieved by the invention specified in the claims, wherein first and substantially in the outside at least partially circumferentially extending around the bearing cavity groove is provided for the dissipation of moisture. The channel is spaced from the opening of the bearing cavity in such a way that, when the housing is inserted into the insertion opening, the channel lies inside or at the rear of the insertion opening. It is therefore deliberately accepted that water can enter into the gap between the outer wall of the cylinder housing and the inner wall of the insertion. The water is then removed through the gutter down. The gutter preferably extends over the vertex of the housing pointing upwards in the installed state. The lowest point of the channel is preferably below the lowest opening of the housing or the storage cavity. The gutter can be 0.5mm to 2mm wide and one round or one round have angular cross-section. The outside may transition to forming a sharp edge or forming a rounding in the gutter. The lock cylinder may be a round cylinder, an oval cylinder or a profile cylinder. The latter has a bearing portion with a substantially circular cross-section and an elongate flange portion. Each of the two ends of the lock cylinder may have a groove. The channel may extend around the housing of the lock cylinder. In a profile cylinder, it may be sufficient if the channel extends at least over the entire cross section of the bearing portion. Preferably, the channel extends on the outside along a section line of the contour axis of the bearing cavity in an intersecting angle intersecting imaginary plane with the outside. This level can be a cross-sectional level. However, the cutting plane can also assume a different cutting angle to the contour axis. The channel can also have a curved course. It is, for example, about 5mm to 15mm, preferably spaced about 10mm from the opening. It can lie in the installed state rearward of the strike plate. But it is also possible that the channel is within the profile opening of the strike plate. The lock cylinder can be a mechanical lock cylinder which has tumbler pins which can be sorted by a correspondingly profiled key into a release position. But the lock cylinder can also have electronic components and each have a knob at its two ends.

The invention also relates to a housing part for a lock cylinder, which is modular. Such lock cylinders can be constructed by juxtaposing housing parts in different lengths. The housing part forming the housing front side is designed according to the invention with a groove described above.

The lock cylinder shown in the figures has a housing 1 made of metal, which has a bearing portion 2, which has a rounded cross-section. The bearing section 2 is followed by an elongated profile section 3. The profile section 3 connects two bearing sections 2 with each other. Each of the two bearing sections 2 has a bearing cavity 4, wherein the bearing cavities 4 of the two bearing sections 2 are aligned with each other. The bearing cavity 4 has an end opening 5. In the bearing cavities 4, an actuating shaft 6 is mounted, which forms a cylinder core and which carries in its center a closing member 11 which cooperates with a mortise lock 13, which is installed in a door 12.

On the door leaf, a fitting plate 9 is mounted, which has a profile opening 15 which corresponds to the profile cross-sectional contour of the housing 1. Through this profile opening 15 of the lock cylinder can be inserted into the lock cylinder opening of the door 12 and the mortise lock 13.

In the in the FIGS. 1 to 9 and 11 to 12 illustrated embodiments are double lock cylinder, each having two end faces 1 ', which protrude from the door leaf or a profile opening 15 of a fitting plate 9.

In the in the FIG. 10 illustrated embodiment is a half cylinder, the end face 1 'protrudes only on one side of the door from the profile opening 15 of the fitting plate 9.

The cylinder core forming an actuating shaft 6 has a Schlüsseleinsteckkanal through which a key with a key secret representing coding notches can be inserted. In the cylinder core and the housing are not shown tumbler pins, which cooperate with the coding notches. With regard to the operation of such a lock cylinder reference is made to the literature mentioned in the introduction to the description. If the actuating shaft is rotated by a suitable key, then the closing member 11 rotates.

Between the inner wall of the profile opening 15 and the outer side 8 of the housing 1, a narrow open joint forms, through which moisture can enter into the space between the fitting plate 9 and the door 12 or mortise lock 13 by the capillary effect. This moisture can then enter the housing 1 via a slot 14, for example, which serves to fasten the actuating shaft 6 by means of a snap ring. To avoid this, the outer side 8 of the housing wall 7 of the bearing section 2 and optionally also the outer side of the profile section 3 is provided with a groove 10. The width W of the channel 10 is between 0.5mm and 2mm. The distance between the channel 10 to the stone side 1 'and to the front side opening 5 of the bearing cavity 4 is about 1cm.

In the in the FIGS. 1 to 4 illustrated first embodiment, the groove 10 extends in the in FIG. 5 The channel 10 thus lies in the profile cross-sectional contour plane and has a channel section 10 'which extends around the bearing section 2 and a channel section 10 "which extends around the profile section 3. The channel section 10' extends The channel section 10 "extends in the installed state over the downward-pointing apex of the housing 1. The two channel sections 10 ', 10" go in the region of the transition of the bearing section 2 in the profile section 3 into each other.

As the FIGS. 6 and 8 show, the cross-sectional contour of the groove 10 may be a rounding. According to the embodiment FIG. 6 the rounded groove forming channel 10 merges into the outside 8 to form an edge rounding. In the in the FIGS. 7 to 9 illustrated embodiments, the channel 10 goes to form a only a slight rounding having edge in the outside 8 over. The FIG. 7 shows the configuration of the channel 10 as a partial groove. The FIG. 8 shows the configuration of the channel as a semi-bow and the FIG. 9 shows the configuration of the channel 10 as a rectangular profile.

While at the in the FIG. 1 illustrated embodiment, the trough 10 rearward of the Beschlagschildes 9, that is outside of the profile opening 15, the channel 10 is located in the in the FIG. 10 illustrated embodiment within the profile opening 15 of the fitting plate 9. In this embodiment, the profile section 3 associated trough portion 10 "does not extend beyond the lower vertex.

That in the FIG. 11 illustrated third embodiment shows an electronic cylinder, which can cooperate with, for example, a radio ID carrier. The actuating shaft 6 carries on its one side an outer knob 16 and on its other side an inner knob 17. The inner knob 17 is permanently coupled to the closing member 11. The outer knob 16 is coupled to the closing member 11 only if the locking authorization of the radio-controlled carrier is suitable. With regard to the operation of such an electronic cylinder, reference is made to the above-mentioned prior art. In this embodiment, the channel 10 extends substantially only over the bearing portion 2 and only a small part of the profile section 3. Again, the channel 10 extends over the upward-facing apex of the housing 1. The lowest point of the channel 10 is only slightly deeper than the lowest point of an opening of the bearing cavity 4 in the form of the slit 14. The moisture entering through the gap between the profile opening 15 and the outside 8 only reaches the marginal edge of the channel 10, which thus forms a dripping edge at which drops form, which can run down inside the channel 10. The moisture thus does not reach the slot 14.

The groove 10 extends as in the FIGS. 1 and 10 represented further over the profile section 3, the droplets forming at the drip edge are guided into the region of the lower profile section 3. When in the FIG. 1 shown circumferential groove 10, the drops are even passed to the lower apex within the trough 10.

The FIG. 12 shows a fourth embodiment of the invention, showing a modular lock cylinder. The housing 1 consists of a plurality of housing parts, which can be combined to vary the length of the housing. The two outer housing parts 18 have a groove 10, as has already been described with reference to the first three embodiments.

The FIGS. 13, 14 and 15 show perspective views of housing parts 18 with differently shaped grooves 10. Die FIG. 13 shows a housing end portion 18, wherein the channel 10 is about 1cm from the housing end face 18 'away and extends around the entire bearing portion 2 and over most of the profile section 3.

The FIG. 14 shows a channel 10 which extends substantially only over the bearing portion 2 and extends only to a small extent over the profile section 3.

The FIG. 15 shows a housing part 18 with a circumferential groove 10th

The arrangement and the shape of the gutters is exemplarily shown differently in the individual embodiments in order to illustrate the variety of possibilities. However, each of the above-described embodiments is also executable with differently shaped grooves, which are able to limit penetration of moisture through the gap between the profile opening 15 and outside 8 only to the channel 10, in which the moisture collects to drip, in order then to be discharged downwards, whereby this takes place at least as far as a profile section of the cylinder core, but preferably up to the lower vertex of the housing 1.

Furthermore, the invention also includes such embodiments in which both housing halves are each equipped with a groove 10 for dissipating moisture in a double lock cylinder, as exemplified in the FIG. 12 is shown.

All disclosed features are essential to the invention. In the disclosure of the application is hereby also the disclosure of the associated / attached Priority documents (copy of the prior application) fully incorporated, including for the purpose of including features of these documents in claims of this application. The subclaims characterize in their optional sibling version independent inventive development of the prior art, in particular to make on the basis of these claims divisional applications.
