Definitions

  • the present invention relates to a connector for a profile cylinder according to the preamble of claim 1.
  • Such connector is e.g. known from EP 0 611 246 A1.
  • Such connectors serve the purpose of the single cylinder a profile cylinder to connect with each other.
  • Such connectors have a transverse thread for the forend screw with which the profile cylinder is fixed in the castle.
  • the connector must also have a stop for the inner face (s) of each of the neighboring ones Offer single cylinders, so from the single cylinders of the profile cylinder a continuously rigid assembly becomes.
  • the intended thickening in the area of the faceplate screw thread is however with regard to the notch effect not without problems. Since also the area of Thickening in the longitudinal direction is relatively short, the thickening carries practically not to increase the strength of the connector in the area of the faceplate screw thread because possible lines of force only over a larger longitudinal area in could form the thickening into it.
  • the short length of the thickening is by no means sufficient for this optimally.
  • a connector is known from EP 0 611 246 A1, which is made up of stamped parts. At least the main one middle stamped part is made of sheet metal. The danger of reducing strength The notch effect becomes clear with this connector reduced. In this way, the connector can be made Manufacture with higher strength than a one-piece milled Interconnects.
  • the advantage of the invention is less Manufacturing costs for a component with increased strength.
  • the cross section of the central sheet steel part the connector the necessary strength.
  • the firmness will significantly increased by avoiding material notches.
  • the thickening which are the end stops for the single cylinder (s) offers, with regard to the notch effect on the Starting points on the sheet steel part are meaningless.
  • the thickening carries the area nothing surrounds the faceplate screw thread to increase strength.
  • the strength-increasing effect predominates, the on the separately molded body of the thickening can be traced back.
  • the sheet steel part should A constant material width over the entire length exhibit. Because the connector increases the strength primarily on tighter tolerances, less notch effect due to surface roughness and less notch effect due to non-existent jumps in the dimensions, the sheet steel part can be made from conventional structural steel his. The use of expensive and tough steel like Chromium nickel steel is therefore not necessary.
  • the thickening can be made from any suitable Simply attach materials to the sheet steel part. Conveniently, however, the thickening is molded from one Plastic formed. Although you get this solution first has been skeptical because of an increase in strength due to molded plastic practically could not take place be found that the positive strength enhancing Effect through better surface and reduced notch effect predominated.
  • a particularly intimate bond between the sheet steel part and then thickened from plastic, when the plastic body splashed around the sheet steel part is, preferably annular.
  • the thickening is elastic to a certain extent on the sheet steel part, the plastic material in the Transverse channels / the constrictions on the sheet steel part.
  • the indentations, transverse channels and constrictions should be such that in the event of a violent attack on the profile cylinder under only elastic then plastic Deformation of the thickened area as large as possible Bending angle of the central sheet steel part is reached before the connector in the area of the forend screw thread tears.
  • the invention is applied to a profile cylinder 1, here consisting of a first half cylinder 2 and one second half cylinder 3.
  • first and second half cylinders identical. Execution cases are possible in which only a half cylinder is used. In other execution cases different half cylinders are used.
  • the connector is used for fastening a cylinder stub opposite the half cylinder with the purpose of causing the lock bit to fall out prevent.
  • the Connector of fixing the profile cylinder in the lock case serves.
  • the connector points in the area of Closes a faceplate screw thread 9, which transversely to the longitudinal direction of the profile cylinder sits in the connector 4.
  • the connector 4 With its longitudinal part 5 on both sides of the Stulpschraubengewindes. In the embodiment shown it sits with its longitudinal part 5 in a recess 10 or 11 of the first or second half cylinder.
  • the connector 4 with transverse seating elements (not shown) set in the respective half cylinder 2 or 3. at the holding elements can be spring pins that in a respective transverse bore 6.1 or 6.2 of the connector 4 are driven in.
  • the cross holes 6.1 and 6.2 are aligned with corresponding cross holes, which are in the half cylinders are introduced.
  • the connector 4 has a thickening 8, which extends around the faceplate screw thread 9.
  • the thickening 8 extends to both sides of the Longitudinal part 5 and takes, as shown in Fig.2, in principle the outer contour of the respective half cylinder 2 or 3.
  • the thickening 8 forms a stop for the adjacent half cylinder 2 and 3.
  • the Contour of the thickening 8 of the respective inner end face 12 or 13 of the first or second half cylinder adapted.
  • the longitudinal direction of the connector 4 is usually in the longitudinal direction and the inner end faces 12 and 13 of the respective half cylinders perpendicular to each other.
  • the thickening 8 therefore jumps perpendicularly from the longitudinal part 5 seen outside.
  • the longitudinal part 5 from one there is one piece continuous sheet steel part, and that the Thickening is part of an additional body that is firmly attached to the sheet steel part.
  • the sheet steel part can fit between the punch and the die be manufactured using the fine stamping process.
  • the plastic body is also ring-shaped is splashed around the longitudinal part 5, the sits Plastic body firmly on the longitudinal part.
  • the plastic body can be anchored on the top edge 20 of the longitudinal part transverse channels 18,19 provided there be where the inner end faces 12, 13 of the single cylinder 2 or 3.
  • the transverse channels 18, 19 are cutouts, so to speak from the top edge 20 and can be overmolded with the Be filled with plastic. This measure anchors the plastic body both in the longitudinal direction of the longitudinal part 5 and the two lateral projections of the thickening 8 against the effects of violence from the outside.
  • the outer contour expediently corresponds to the thickening 8 - as Fig.2 shows - in principle the outer contour of the Profile cylinder 1 in the lower area, so that the thickening 8th is integrated into the overall contour of the profile cylinder 1.
  • a constriction 21 is provided, starting from jumps from the lower edge 22 into the sheet steel part.
  • This constriction 22 corresponds to the upper transverse channels 18.19 also sprayed with plastic. This offers the Advantage of increased transverse strength and the possibility for the transverse plastic material, at Violent attack on the profile cylinder 1 on the material of the longitudinal part 5 also support in the longitudinal direction.
  • Constriction 21 is provided with a rounded outlet zone 23.
  • the bottom of the constriction 21 is therefore rounded Way to the lower edge 22 of the longitudinal part 5.
  • the continuous one-piece longitudinal part offers 5 the greatest possible resistance to destruction because of the load-bearing area of the longitudinal part 5 in the area of the face screw thread 9 the entire remaining cross section of the metallic longitudinal part 5 corresponds.
  • the side protrusions the thickening 8 would be in terms of strength properties of the connector 4 anyway only from a subordinate Importance.
