STORAGE FOR ONE WING ON A FRAME

Description

[0001] The invention relates to a bearing for a sash on a frame of a window, a French window or the like, comprising a bearing bolt, a bearing shell, a bearing sleeve inserted into the bearing shell for supporting the bearing bolt, an adjusting screw screwed into the bearing shell and supporting a free end of the bearing bolt, and a holding device for preventing rotation of the adjusting screw.

[0002] Such bearings allow the sash position relative to the frame to be adjusted using the adjusting screw. The sash is raised or lowered by turning the adjusting screw, which rests on the free ends of the bearing pin.

[0003] EP 1 405 975 A1 describes an adjustable door hinge assembly. The bearing of a door has a leaf-side and a frame-side fitting part, which are referred to as hinge plates and hinge pins, respectively, and which are connected to one another by a hinge pin. The bearing shown is characterized by the fact that it can be readjusted even after pre-assembly in order to ensure optimal support of the door leaf on the door frame. The bearing assembly comprises a sleeve which is arranged between the hinge plate and hinge pin and radially encloses the hinge pin to increase the protection of the assembly against tampering and contamination. A chamfered edge of the sleeve, which interacts with a chamfered transition area of ​​the hinge pin, holds the sleeve securely in position so that it reliably covers the transition area between the hinge plate and hinge pin.A threaded bolt intended for adjusting the hinge pin is held in its adjusted position by a fixing screw.

[0004] FR 2 713 270 A1 describes an adjustable sash hinge comprising a frame-side and a sash-side fitting, as well as a hinge pin that can be adjusted in three directions. For this purpose, adjustment options are located on the frame-side hinge, allowing adjustment both perpendicular to the sash plane and horizontally to it. The sash-side fitting contains an adjusting screw that allows for height adjustment of the sash. This adjusting screw is secured in the set position by a locking screw aligned perpendicular to it.

[0005] EP 1 835 101 A2 describes a bearing for a sash mounted on a frame. The bearing has two frame-side fittings that serve as the upper and lower ends of the bearing, and a sash-side fitting that, in the installed position, is arranged between the two frame-side fittings. The invention comprises two bearing bolts, each connecting a frame-side fitting to the sash-side fitting. The bearing bolts can be rotated in their guides and thus serve to regulate the distance between the respective frame-side fitting and the sash-side fitting. To fix the rotatable bearing bolts, the frame-side fittings each have a ring nut, which can be tightened after the bearing bolts have been set to the desired position, thus preventing undesired adjustment of the sash bearing after installation.

[0006] EP 2 256 276 A2 discloses a corner bearing in which the holding device is connected to a peripheral surface of the adjusting screw and holds the adjusting screw in a force-fitting manner. For this purpose, the holding device has a sleeve that encloses the peripheral surface of the adjusting screw. To adjust the sash position, the adjusting screw can be turned after the force-fitting connection has been overcome by the sleeve and is then held in its position. When the sash is opened or closed, the bearing pin is turned relative to the adjusting screw. However, to prevent the adjusting screw from being pulled along and thus the sash position from being adjusted, the holding device must exert very high holding forces on the adjusting screw. The sleeve also requires an additional, cost-intensive component to be installed.

[0007] DE 33 42 842 A1 discloses a corner bearing in which a slider is arranged between an adjusting screw and a hinge pin. This decouples the adjusting screw and hinge pin. However, the arrangement of the slider results in very large structural dimensions for the bearing. The slider also requires an additional, cost-intensive component to be installed.

[0008] The invention is based on the problem of developing a bearing of the type mentioned at the outset in such a way that it can be produced particularly cost-effectively and avoids independent adjustment of the adjusting screw.

[0009] This problem is solved according to the invention in that the holding device is arranged on the bearing sleeve and in that the holding device has a web which is held non-rotatably in the bearing shell and when the web projects into a threaded section of the adjusting screw.

[0010] This design avoids the need for additional components, as the bearing sleeve is already inserted into the bearing arrangement. The arrangement of the holding device on the bearing sleeve has the advantage of a particularly small number of bearing components. The bearing arrangement is therefore particularly cost-effective to manufacture. Since the bearing bolt and the bearing sleeve already have a friction pair, the arrangement of the holding device on the bearing sleeve provides direct support for the adjusting screw. This reliably prevents the adjusting screw from becoming self-adjusting. The design according to the invention means that the thread of the adjusting screw presses into the web, which is held against rotation. The adjusting screw is thus reliably held by the web in a force-fitting manner. Preferably, an internal thread on the bearing sleeve is prefabricated, and the web is raised in such a way that the adjusting screw plastically forms the threaded section into the web when screwed into the bearing sleeve.The shape of the bridge can be varied.

[0011] According to another advantageous embodiment of the invention, the assembly of the bearing sleeve with the web is particularly simple if the web is arranged parallel to the rotational axis of the adjusting screw. This allows the bearing sleeve with the web to be easily inserted into the bearing shell.

[0012] According to another advantageous development of the invention, it contributes to a further reduction of the manufacturing costs of the bearing if the web is manufactured in one piece with the bearing sleeve.

[0013] According to another advantageous development of the invention, the web is made of plastic to further reduce the manufacturing costs of the bearing. Preferably, the plastic is plastically deformed when the adjusting screw is screwed in and then secures the adjusting screw with a force fit against rotation. By selecting the appropriate plastic, the holding forces of the holding device and the plastic deformation of the web can be easily adjusted.

[0014] According to another advantageous development of the invention, a reliable and non-rotatable mounting of the web in the bearing shell can be easily ensured if the web is arranged in a recess of the bearing shell.

[0015] In bearing shells designed as bearing strips, the positioning of the web in the recess can be particularly easily ensured if the web is supported behind the end of the bearing strip. In such bearing shells, a recess is already present behind the end of the bearing strip, which can be used to prevent twisting.

[0016] According to another advantageous embodiment of the invention, rotation of the bearing sleeve in the bearing shell can be avoided if the bearing sleeve has a projection on its outer side and if the projection penetrates a recess in the bearing shell. Such rotation of the bearing sleeve in the bearing shell is usually undesirable if the intended friction pairing is arranged between the bearing pin and the bearing sleeve.

[0017] According to another advantageous development of the invention, the bearing sleeve is structurally particularly simple if the bearing sleeve has a tubular section for supporting the bearing pin and if the web protrudes from the tubular section.

[0018] According to another advantageous development of the invention, the bearing can be manufactured particularly cost-effectively if the bearing sleeve is manufactured as a single piece with the web. This single-piece construction is preferably made of plastic.

[0019] The invention permits numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and is described below. This shows in Fig. 1 shows a section of a window with a bearing, Fig. 2 shows an enlarged longitudinal section through the bearing Figure 1 , Fig. 3 a sectional view along the line III - III through the bearing from Figure 2, Fig. 4perspective of a bearing sleeve with a holding device of the bearing.

[0020] Figure 1 shows a corner area of ​​a window with a sash 2 that can be pivoted and tilted against a frame 1. The sash 2 is hinged to the frame 1 via a bearing 3. For clarification, Figure 1 a horizontal axis 4 and a vertical axis 5 are drawn around which the wing 2 can be tilted or pivoted.

[0021] Figure 2 shows a longitudinal section through the bearing 3 from Figure 1The bearing 3 has a frame-side fitting 6 and a sash-side fitting 7. The frame-side fitting 6 has a base 8 with a horizontal bearing axis 9 for a vertical bearing pin 10. The sash-side fitting 7 has a bearing shell 12 with a bearing hinge 11 and an adjusting screw 13 screwed into it. Furthermore, a bearing sleeve 14 for the pivotal mounting of the bearing pin 10 is arranged within the bearing shell 12. A plug 15 closes the open end of the bearing shell 12.

[0022] The bearing shell 12 has an internal thread 16 for a threaded section 17 of the adjusting screw 13. A support section 18 of the adjusting screw 13 protrudes into the bearing sleeve 14 and rests against the free end of the bearing pin 10. By screwing the adjusting screw 13 in or out, the relative positions of the fittings 6, 7 and thus the sash position can be adjusted. The support section 18 of the adjusting screw 13 has a smaller diameter than the threaded section 17.

[0023] To prevent the adjusting screw 13 from rotating unintentionally, a retaining device 19 is provided with a web 20 extending into the threaded portion 17. The web 20 is held non-rotatably in the bearing shell 12 and is plastically deformed when the adjusting screw 13 is screwed in.

[0024] Figure 3 shows the bearing 3 from Figure 2in a sectional view along line III-III. It can be seen that the web 20 of the holding device 19 is held in a rotationally fixed manner in a recess 21 created by the bearing strip 11. Furthermore, the web 20 has dimensions that ensure a frictional connection when the adjusting screw 13 is screwed in.

[0025] Figure 4 shows in perspective a one-piece unit consisting of web 20 and bearing sleeve 14. The contour of the web 20 extends as an elongated projection 22 over the outer contour of the bearing sleeve 14, so that the bearing sleeve 14, as Figure 3described, is also held in the bearing shell 12 in a rotationally fixed manner by the recess 21 created by the bearing strip 11. The one-piece unit comprising web 20 and a tubular section 23 of the bearing sleeve 14 can preferably be manufactured from plastic by injection molding. The inner side of the web 20 terminates seamlessly with the inner side of the tubular section 23 of the bearing sleeve 14.
