Definitions

  • the invention relates to a device for locking a folding part that can be pivoted about an axis, in particular a window or a roof hatch of a vehicle that can be pivoted out into at least one position, according to the features of the preamble of patent claim 1 or 5.
  • folding parts e.g. B. windows or skylights application that can be placed in different positions.
  • the folding parts are determined in such a way that the folding part does not swivel unintentionally, even when the vehicle is shaken or the wind is blowing.
  • both hands In order to bring a folding part into a new position and to lock it there, usually both hands have to be used. For example, one hand grips a handle to swing the folding part out, while the other hand operates a locking mechanism. This type of operation is cumbersome and uncomfortable, especially when the folding part or its locking mechanism is difficult to access.
  • the US-A-2,550,008 describes a device for locking a folding part with the features of the preamble of claim 1 or 5.
  • the extension in the groove of the guide rail is here at the outermost free end of the guide rail, so that the folding part is only in a completely open position locks.
  • the hatch cover can be brought into different opening positions and locked there.
  • the hatch cover Backdrop with several detent positions designed as bulges, into which the pin of a locking lever articulated in the roof cutout engages.
  • the pin is braced on one side in the direction of the bulges by an M-shaped leaf spring. This is intended to enable the pin and thus the hatch cover to be securely latched in, so that the latching position is maintained even when shaken.
  • the formation of the backdrop in the hatch cover frame represents a relatively complex work process. Furthermore, when opening and closing the hatch cover, the resistances of the latching positions must be overcome.
  • the known device does not offer secure locking even under extreme conditions.
  • the object underlying the invention is seen in designing a locking device according to the features of the preamble of claim 1 or 5 so that it enables reliable locking of a folding part even when shaken in predetermined locking positions, is simple to manufacture and easy to use.
  • the object is achieved by the characterizing features of claim 1 or 5.
  • the backdrop is designed such that it usually covers the extension of the guide rail and only releases when it reaches a locking position, so that in this position the pin can engage in the extension of the guide rail and can be supported on a side surface of the extension.
  • the pin slides along the groove until it reaches an extension (indentation). If this indentation is not covered by the backdrop, the pin slides into the indentation and is supported on a side surface of the indentation, as a result of which the folding part is held in this position.
  • the positive connection is preferable to a frictional connection, since it adjusts itself automatically without additional measures (second hand), and ensures reliable locking even in the event of strong vibrations and shocks and, if necessary, in the event of a headwind. If, however, the indentation is covered by the backdrop, there is no locking here. Rather, the folding part can be pivoted further, the pin sliding further along the groove until it reaches a further indentation or the groove end, if necessary.
  • the locking device according to the invention can be implemented inexpensively by simple stamped or bent parts and takes up very little space. It can be in an area inaccessible to the operator since no direct actuation of the mechanism is required.
  • This locking device can be used particularly advantageously in the case of front or rear windows or in the roof hatches of vehicles, in particular of work vehicles such as agricultural tractors, which are to be kept open in various positions.
  • An arrangement of the guide rail parallel to a gas spring, the gas pressure of which is used to provide the opening pressure for the folding part, is particularly advantageous.
  • the setting has a longitudinal groove with an indentation, the shape of which corresponds to the indentation in the guide rail groove and into which the pin also engages.
  • the link groove is shorter than the guide rail groove, so that when the folding part is opened and closed, the ends of the link groove are quickly reached and the link is moved along the guide rail by the pin.
  • the guide rail can be arranged so that it pivots due to the force of gravity acting on it about its pivot bearing position when the locking position is reached, so that the pin engages in overlapping indentations.
  • this pivoting movement can also advantageously be brought about and supported by attaching a spring, preferably a torsion spring.
  • the indentation is expediently designed asymmetrically and has a recessed and an obliquely tapering side flank.
  • the recessed flank picks up the pin in the locking position and prevents the guide rail from jumping out of the locking position and preventing the folding part from moving further (e.g. opening). If the locking device is designed such that the opening in the locking position is positively avoided when the folding part is opened further, the recessed flank will expediently be located on the side of the indentation facing away from the pivot bearing point of the guide rail.
  • the link can preferably only be moved by overcoming sliding friction forces.
  • resilient tabs can be formed on the backdrop, which resiliently abut the guide rail and produce a frictional connection.
  • At least one power drive generating a pivoting force is arranged between the folding part and the receiving part and, in a locking position, presses the pin against the recessed flank of the indentation.
  • the power drive is, for example, a hydraulic or mechanical spring element, for example a hydraulic cylinder or a gas spring. The latter is a cheap, commercially available component.
  • the power drive is designed so that, depending on the application, it can pivot the folding part away from or towards the receiving part. With skylights, it is advisable to use the driving force to open the hatch. In the locking position, the recessed flank of the indentation prevents further opening due to the effect of the power drive.
  • the locking device and the power drive are preferably arranged approximately in parallel and essentially designed as an assemblable structural unit.
  • the driving force is dimensioned such that it is sufficient to pivot the pivoting part into its maximum position, for example against gravity.
  • the swivel part should also be held reliably in the event of vibrations or, where appropriate, wind. It is advantageous if the driving force is 1.7 times the value that would be required to keep the folding part in its maximum position in equilibrium.
  • the force that can be applied by hand to pivot the folding part must be taken into account.
  • gravity can also be used in some cases to preload the folding part in the direction of a pivoted-out position.
  • the invention further relates to the roof hatch of a vehicle, in particular an agricultural or construction vehicle, with a locking device according to the invention.
  • FIG. 1 shows the detail of an agricultural tractor roof 10 into which a roof hatch 12 is embedded.
  • the roof hatch 12 is shown in the half-open position. It can be pivoted about an axis, which is formed by two hinges 14, relative to the frame part 16, which is defined in the roof 10 and is designed as a receiving part.
  • the frame part 16 In the frame part 16, the usual sealing elements are integrated, which allow a rainproof closure.
  • the roof hatch 12 can be opened and closed from the inside by gripping with one hand a handle which is arranged on the hatch surface and is not visible in the figure and is actuated in the vertical direction.
  • the locking device 18 according to the invention is indicated between the frame part 16 and a frame of the roof hatch 12 (not shown in more detail). If necessary, a second locking device can be attached parallel to this locking device 18 on the other side of the roof hatch 12.
  • the locking device 18 is shown in more detail in FIG. 2. It essentially consists of a gas spring 20, a guide rail 22 and a link 24. The guide rail 22 and the link 24 are shown in detail in FIGS. 3 to 6.
  • the gas spring consists essentially of a gas pressure cylinder 26 and a piston rod 28.
  • the free end of the gas pressure cylinder 26 carries a tab 30 which is articulated by means of a bolt 32 with two tabs 34, 36 fastened to the frame of the roof hatch 12.
  • the free end of the piston rod 28 also carries a tab 38 which is pivotally mounted by means of a bolt 40 between two tabs 42, 44 fastened to the frame part 16 of the outer roof.
  • the gas spring 20 is biased such that it strives to push the piston rod 28 out of the gas pressure cylinder 26. It thus applies a pivoting force that opens a non-locked roof hatch 12 and holds it in an open position.
  • the spring force of the gas spring 20 is designed such that it is greater by a factor of 1.7 than the minimum force required to open the roof hatch 12.
  • the guide rail 22 is arranged between the pin 48 and the bolt 40. 5 and 6 show, the guide rail 22 consists essentially of a flat metal strip which has a bore 50 at one end.
  • a longitudinally extending groove 52 extends approximately over the entire length of the guide rail 22.
  • This groove 52 has an indentation (extension) 54 on one side.
  • the indentation 54 is designed asymmetrically. Its flank 56 facing the bore 50 is designed such that the indentation 54 runs obliquely into the groove 52.
  • the opposite other flank 58 is designed to spring back, so that a protruding nose 60 forms between indentation 54 and groove 52.
  • the bore 50 receives the bolt 40, so that the guide rail 22 can be pivoted about this bolt 40.
  • the pin 48 is slidably disposed in the groove 52.
  • a lock washer 62 is attached to the outer end of the pin to prevent the guide rail 22 from sliding off the pin 48.
  • 3 and 4 represent the backdrop 24. It is a part formed from sheet metal, which is essentially C-shaped in cross section (FIG. 4).
  • the link 24 can be pushed in the longitudinal direction over the guide rail 22, so that the two free legs 64, 66 engage around the guide rail 22.
  • the link 24 In its base part 68, the link 24 has a groove 70 which extends essentially over its entire length. This groove 70 corresponds to the groove 52 of the guide rail 22, even if it is not quite as long overall.
  • the groove 70 widens into an indentation 72.
  • This indentation 72 is designed in terms of its width and its steep flank 74 corresponding to the indentation 54 of the guide rail 22, even if the special design of the nose 60 can be omitted in the setting 24.
  • the indentations 54, 72 lie on the upward-facing side of the guide rail 22 or the link 24.
  • the pin 48 reaches these indentations 54, 72, the guide rail 22 tilts somewhat downwards due to its gravity, so that the Pen 48 penetrates into the area of the indentation 54, 72.
  • a torsion spring 84 is provided, which is wound around the pin 40 designed as a pivot bearing and is supported at one end on the frame part 16 and at the other end on the guide rail 22.
  • the functioning of the locking device is as follows: When the roof hatch 12 is opened, the gas spring 20 extends completely, since the indentation 54 of the guide rail 22 is initially covered by the base part 68 of the link 24. Only in the last phase of the opening movement does the pin 48 reach the groove end 80, so that when it is opened further, the link 24 on the guide rail 22 is displaced towards its free end. When the end position is reached, the two indentations 54, 72 of the guide rail 22 and link 44 overlap. When the roof hatch 12 begins to close, the link 24 initially remains in its exposed position relative to the guide rail 22 due to the spring force of the tabs 76, 78.
  • the guide rail 22 folds down due to its gravity and the torsion spring 84, so that the pin 48 penetrates into the region of the indentations 54, 72. If the closing process is ended in this position and the roof hatch 12 is released, an opening movement starts again as a result of the force of the gas spring (20), but this is interrupted as soon as the pin 48 has reached the recessed end region 58 of the indentation 54. Opening the roof hatch 12 beyond this stop is now not possible. The roof hatch 12 remains in this middle position because it is open due to the pressure force of the gas spring 20 is held. Closing is only possible by overcoming the gas spring force.
  • the pin 48 reaches the lower end 82 of the link 24, so that, upon further closing, the link along the guide rail 22 overcoming the frictional force exerted by the resilient tabs 76, 78 is moved towards the pivot bearing point 50.
  • the indentation 54 also closes again, which is covered by the base part 68 of the link 24, whereby the starting position is reached again.
  • the locking position can thus only be achieved by first opening the roof hatch 12 completely and then moving it back into the semi-closed locking position. From this locking position, the roof hatch 12 can no longer be opened, but can only be closed by overcoming the gas spring force. Since the locking mechanism does not need to be actuated when the roof hatch 12 is opened and closed, it can be attached at a location which is not accessible to the operator.
