Definitions

• the present invention relates to an interchangeable cylinder system for locks according to the preamble of claim 1.
• Generic changeover cylinder systems consist of a cylinder housing and a lock cylinder which can be inserted into this cylinder housing and which is replaceably held in the cylinder housing and can be rotationally adjusted by means of a key which fits into the lock cylinder between an open and a closed position.
• the lock cylinder is provided on its front side with a collar which is radial to the longitudinal axis of the lock cylinder for the lateral surface of
• Latches protruding and axially abuts an end face of the cylinder housing to cover the end face of the cylinder housing.
• a disadvantage of this change-cylinder system is that the change-cylinder system is not to see whether the lock cylinder is currently in its closed position or in its open position. Thus, there is the danger, for example, cabinets whose doors are equipped with such an exchange cylinder system and are always kept closed for safety-related reasons, to leave unintentionally in its open position.
• the object of the present invention is therefore to provide an interchangeable cylinder system for locks in which it can be seen at a glance whether the lock cylinder is in an open or a closed position. This object is achieved by an exchange cylinder system having the features of claim 1.
• the collar of the lock cylinder has a recess in order to make visible a partial surface of a display element, which is arranged on the lateral surface of the lock cylinder facing side of the collar and positionally fixed with respect to the cylinder housing attachable.
• the collar-facing surface of the display element is provided with at least one mark, so that the opening and closing position of the lock cylinder is read at the respectively visible by the recess of the lock cylinder marker.
• the display element is formed as an annular plate.
• Such designed as a plate display element has the advantage that it can be retrofitted in an easy way in existing cylinder systems without having to make additional structural changes to the cylinder housing. Only the collar of the lock cylinder must have a recess so that a surface element of the display element is visible.
• the display element is designed as a mountable on the front side of the cylinder housing and removable again component. As a result, a simple replacement of the display element is possible without major installation effort.
• the display element is formed integrally with the cylinder housing.
• the front side of the cylinder housing in different color or Shades of gray is colored at the respective opening or closing position and can be dispensed with in this way on an additional component entirely.
• FIG. 1 shows a schematic perspective view of a first embodiment of a change-cylinder system according to the invention
• FIG. 2 is a front view of the change cylinder system of Figure 1 in the closed position
• FIG. 3 is a front view of the exchange cylinder system of FIG. 1 in the opening position
• FIG. 4 is a schematic perspective view of a second embodiment of an exchange cylinder system according to the invention.
• FIG. 5 is a front view of the change cylinder system of Fig. 4 in the
• Fig. 6 a front view of the exchange cylinder system of Figure 4 in the open position.
• FIGS. 1 to 3 show a first embodiment of a Konzylindersys- system 1, which consists essentially of a cylinder housing 2 and a can be inserted and pulled out into the cylinder housing 2 lock cylinder 3.
• the lock cylinder 3 is axially rotatable between an open position and a closed position in the cylinder housing 2 to the longitudinal axis of the lock cylinder 3 and the cylinder housing 2.
• the angle of rotation by which the lock cylinder 3 must be rotated in the change cylinder system 1 shown in FIGS. 1 to 3 in order to change from an open position to a closed position is 90 ° here.
• this twist angle is 180th
• the cylinder housing 2 is insertable into a cylindrical bore of a door, a window or the like. It has at a front end face 5, a groove 6 into which the lock cylinder 3 is inserted. At the opposite end face of the cylinder housing 2 a beyond the end face extending base plate 14 is attached, with which the cylinder housing can be fixed to the door, the window or the like. Behind this base plate 14 is a bolt 15 perpendicular to the longitudinal axis of the cylinder housing 2 from the cylinder housing 2, which is in a strike plate (not shown) can be inserted, which is attached for example to a door frame and on which the door provided with the cylinder housing 2 are locked should.
• This latch 15 is coupled to the lock cylinder 3 in such a way that a rotation of the lock cylinder 3 is accompanied by an axial rotation of the lock 15 about the longitudinal axis of the lock cylinder 3.
• the lock cylinder 3 has a collar 8 which protrudes radially to the longitudinal axis of the lock cylinder 3 via the lateral surface 7 of the lock cylinder 3 and axially abuts an outer or inner end face 5 of the cylinder housing 2. If the collar 8 bears against the outer end face 5 of the cylinder housing 2, the collar 8 completely covers the cylinder housing 2 in the state pushed into the cylinder housing 2.
• the front side of the collar 8 is provided with a slot 9 into which a key (not shown) matching the lock cylinder 3 can be inserted and with which the lock cylinder 3 can be rotationally adjusted in front of an opening position into a closed position or vice versa.
• the front surface of the collar 8 is formed substantially circular, wherein a part of the surface is interrupted by a recess 10, which extends from the periphery of the collar 8 forth to a narrow side of the slot 9.
• the positioning of the recess 10 on the collar 8 of the lock cylinder 3 is also conceivable as a viewing window in the sense of a bore.
• recess 10 it is also conceivable arrangement of the recess 10 at another position. Important here is the interaction of recess 10 and to be described display element 4, which is arranged directly between the end face 5 of the cylinder housing 2 and the collar 8 of the lock cylinder 3.
• This display element 4 which is preferably formed as an annular plate, is positionally fixed to the preferably flat end face 5 of the cylinder housing 2 attachable.
• the positionally fixed arrangement of the display element 4 is preferably carried out by locking lugs 13 which protrude from the front side 5 of the cylinder housing 2 facing surface of the display element 4 and in RastausEnglishun- conditions 6 on the front side 5 of the cylinder housing 2 can be latched. Due to the design as preferred thin-walled annular plate, the display element 4 is easily mounted on existing cylinder housings 2, so that the display element 4 as well as the lock cylinder 3 is suitable for retrofitting existing Meszylindersy systems.
• the assembly of the display element 4 is effected for example by simply plugging the display element 4 on the lateral surface of the lock cylinder 3.
• the display element 4 is pressed against the end face 5 of the cylinder housing 2 and then only needs be rotated into its predetermined position in which the detents 13 of the display element 4 engage in the present in a known from the prior art lock cylinder 3 locking recesses 6.
• the lock cylinder 3 facing surface of the display element 4 is provided with at least one mark 11, 12, so that the opening position and the closed position of the lock cylinder 3 at the respectively through the recess 10 of the lock cylinder 3 visible mark 1 1, 12 can be read.
• these markings are formed as a color marking or as the respective rotational position of the lock cylinder 3 indicative word mark.
• the area of the display element 4, in which the lock cylinder 3 is in its open position marked by a blue coloration
• the area of the display element 4, in which the lock cylinder 3 is in its closed position marked by a red coloration.
• the lock cylinder 3 is in its open position, the recess 10 of the collar
