Definitions

  • the invention betn 'fft a fastening device for axial fixing of a pivoted threaded pin in a closing element, in particular sondere a door according to the preamble of claim 1. Furthermore, the invention relates to a shutter actuator for actuating a comparison circuit element and a closing element, in particular a door, with egg nem actuating element, a closure element, in particular a sash tongue, and a closure actuation.
  • Corresponding fastening devices are used in many areas of technology in order to fasten threaded pins to locking elements, such as doors, flaps, windows or hatches, and to prevent axial movement of the threaded pins.
  • an actuating element for example in the form of a doorknob, is located on the outside of the reel and on the inside a locking element, such as a sash tongue. Via a movement of the actuating element, the closure element can then be moved back and forth between a locking position in which the closing element is locked and an unlocking position in which the closing element can be opened.
  • set screws can be used, via which the actuation element and the closure element are rotationally coupled to one another.
  • this usually has a hole.
  • the grub screw is then connected to the actuating element and on the opposite inside of the door in a corresponding manner to the closing element.
  • fastening elements are generally used, which can be screwed onto the setscrews, for example in the manner of a nut.
  • these fasteners rest against the inside of the locking element and thus prevent axial movement of the threaded pin relative to the locking element. Since the fastening elements move together with the threaded pin relative to the closing element when the closing element is actuated, it can happen, however, that the fastening element detaches from the threaded pin and moves in the axial direction, so that this no longer reliably secures the threaded pin can guarantee.
  • a reverse rotation lock it can be, for example, a lock nut which is screwed onto the fastening elements screwed onto the threaded pin and thus prevents the fastening elements from loosening unintentionally.
  • O-rings can be used which can be arranged in the bore of the closing element through which the threaded pin extends. With such a seal, gas exchange can be largely prevented, even when the threaded pin is rotated, but it is disadvantageous that the threaded pin must first be provided with a groove for the O-ring, which makes such a construction comparatively complex .
  • the invention provides the task of specifying a fastening device for axially fastening a rotatably mounted threaded pin, which enables a reliable seal by means of structurally simple means.
  • the anti-rotation device has a sealing area for sealing the threaded pin with respect to the closing element.
  • the set screw can thus be reliably sealed with respect to the closing element via the anti-rotation lock. It is not possible that through the bore in the closing element through which the threaded pin extends, there is a gas exchange between the inner space and the outer space. It is no longer necessary to provide the threaded pin with a groove or the like in order to arrange a sealing element thereon. Nevertheless, the threaded pin is also axially secured by the fastening device. It has also proven to be advantageous if the reverse rotation protection is arranged between the closing element and the fastening device. With this arrangement, the reverse rotation lock can interact both with the threaded pin and with the closing element and thus a reliable seal of the threaded pin with respect to the
  • the sealing area of the anti-rotation device has a radial sealing section.
  • the radial sealing section can serve to reliably seal the anti-rotation lock against the threaded pin.
  • the radial sealing section can be pressed radially to the longitudinal axis of the threaded pin into the threads of the threaded pin.
  • the fastening element has a first pressing area which is designed such that when the fastening element is screwed onto the thread, the radial sealing section is pressed radially onto the threaded pin.
  • the first pressing area When the fastening element is screwed on, the first pressing area interacts with the anti-rotation lock, so that the first sealing section, which is designed as a radial sealing section, is pressed onto the threaded pin.
  • the Contact pressure can be adjusted using the fastener. The more the fastening element is tightened, the more the first sealing section is pressed onto the threaded pin.
  • the design of the pressing area it has proven to be advantageous if it is designed such that when the fastening element is screwed onto the threaded pin, the radial sealing section of the anti-rotation lock is pressed evenly onto the threaded pin on the circumference.
  • this first sealing section is uniformly pressed onto the threaded pin on the circumference results in a reliable seal of the anti-rotation device with respect to the threaded pin.
  • the sealing section can be pressed evenly onto the sealing section in the radial direction, so that the sealing section deforms evenly when pressed on.
  • the radial sealing section can be elastically deformed by the first pressing area when the fastening element is screwed on, so that the pressing area presses the sealing area into the threads of the threaded pin.
  • the first pressing area can be designed conically in the manner of a funnel or a blunt hollow cone.
  • the larger opening can face the reverse rotation lock.
  • the smaller opening can open into the threaded hole of the fastener.
  • the first pressing area can have a pressing inclined surface.
  • the first pressing area can project in the axial direction.
  • the sealing area can be pressed onto the threaded pin in the radial direction by a pressing force of the first pressing area acting in the axial direction.
  • the radial sealing section can be bulged in the direction of the fastening element.
  • the pressing force acting on the sealing section from the pressing region can be oriented perpendicular to the sealing force acting in the radial direction.
  • the first Sealing section can be conical at least in sections. Due to an axial pressing force acting on the conical surface, the sealing section can be pressed radially onto the threaded pin due to the flank angle of the conical surface.
  • the first sealing section can have a curvature which enables an axial pressing force to result in the sealing section being pressed on radially.
  • the shape of the first pressing area and the first sealing section can be coordinated with one another.
  • the sealing area has an axial sealing section for sealing the anti-rotation lock against the closing element.
  • the axial sealing section can be designed as a second sealing section of the sealing area. The axial sealing section can be pressed onto the inside of the closing element and thus lead to a reliable seal of the anti-rotation device with respect to the closing element.
  • the axial sealing force of the second sealing section acting in the axial direction is less than the radial sealing force of the first sealing section acting in the radial direction Profit dest.
  • the axial direction can extend parallel to the longitudinal axis of the threaded pin.
  • the axial sealing section is arranged on an end face of the reverse rotation lock. With this arrangement, the axial sealing section can effect a reliable device of the anti-rotation device with respect to the closing element.
  • the axial sealing section has a sealing lip for interacting with a sealing element arranged groove.
  • the required axial sealing force can be reduced by the interaction of the sealing lip and the groove.
  • the sealing lip can be designed in the manner of an O-ring and arranged concentrically to the threaded pin. This configuration enables a reliable seal to be maintained when the threaded pin and the anti-rotation lock are turned.
  • the sealing lip and the groove can also interact in the manner of a labyrinth seal. This enables a smoother actuation of the threaded pin, since the axial sealing force can be even lower in this case.
  • the side of the axial sealing section facing the closing element can be designed as a sliding surface. This also makes it easier to move the threaded pin.
  • the fastening element has a second pressing area which is designed in such a way that when the fastening element is screwed onto the threaded pin, it axially presses the axial sealing section onto the closing element.
  • the second pressing area can act on the axial sealing section in the axial direction.
  • the reverse rotation lock can be plugged onto the threaded pin in a non-rotatable manner.
  • the anti-rotation lock can be plugged onto the threaded pin in the axial direction, but it cannot be turned with respect to the threaded pin.
  • the anti-rotation lock and the grub screw can be rotationally coupled.
  • the anti-rotation lock and the threaded pin can be positively connected to one another at least in the direction of rotation. It has also been found to be advantageous with regard to the connection of the anti-rotation lock with the threaded pin if the reverse rotation fuse has a polygonal recess for receiving the threaded pin.
  • the recess can be matched to the cross section of the threaded pin.
  • the set screw preferably also has a polygon-shaped cross section. This enables a reliable interlocking connection, so that a rotational movement of the threaded pin also leads to a corresponding rotational movement of the reverse rotation lock.
  • Polygonal is not only to be understood as cross-sections formed by straight lines, but rather all cross-sections that deviate from a purely circular cross-section and thus enable a positive connection. Even oval or circular cross-sections with a notch are to be understood as polygonal. It has proven to be particularly advantageous if the threaded pin has a square cross section, possibly with rounded corners.
  • the grub screw can thus be designed as a square grub screw. Such a threaded pin is easy to manufacture and enables a reliable, positive connection with the reverse rotation lock.
  • the recess of the anti-rotation lock can thus also preferably be a square recess, possibly with rounded corners.
  • the radial sealing section is arranged around the recess. It is particularly advantageous if the recess extends through the radial sealing section. This enables a reliable seal if the radial sealing section is pressed onto the threaded pin in the radial direction.
  • the reverse rotation lock can be connected to the fastening element. Since the reverse rotation lock can only be moved in the axial direction with respect to the threaded pin and the fastening element can be screwed onto the setscrew, but not like the anti-rotation lock is axially attachable, the two fastening elements secure one another when they are connected to one another.
  • the anti-rotation device can no longer be moved in the axial direction when the fastening element is unscrewed and the fastening element can no longer be rotated, since the anti-rotation device prevents such a rotational movement.
  • the anti-rotation lock and the fastening element can be releasably connected to one another. This enables easy removal of the fastening device.
  • the anti-rotation device can be locked with the fastening element.
  • a latching enables a simple and self-locking connection. If the fastening element is screwed onto the threaded pin, it can automatically lock with the anti-rotation lock. The fastening element can then only be screwed further onto the threaded pin, but can no longer be unscrewed, since a corresponding movement is prevented by the reverse rotation lock. At least in the direction of rotation, the reverse rotation lock is then positively connected to the fastening element.
  • the reverse rotation lock can act like a ratchet for the fastening element, which only allows movement in one direction of rotation.
  • the reverse rotation lock has a latching toothing with several latching steps.
  • the locking teeth can be designed in the manner of a locking ring projecting in the axial direction.
  • the locking ring can be arranged concentrically around the recess of the anti-rotation lock and thus also be arranged concentrically to the longitudinal axis of the threaded pin.
  • the locking teeth or the individual teeth of the locking teeth can extend in the radial direction, in particular outwards, away from the threaded pin.
  • the individual teeth of the locking teeth can be designed as saw teeth. This enables in a simple manner that only one rotation is prevented in one direction of the fastening element.
  • the fastening element can have a locking toothing for engaging in the locking toothing of the reverse rotation lock.
  • the locking teeth can have several locking teeth, which can be designed in the manner of saw teeth. This configuration enables the locking toothing and the locking toothing to cooperate in such a way that the fastening element can only be rotated in one direction. If the ratchet teeth engage in the locking teeth, the fastening element can only be screwed further onto the threaded pin, but can no longer be unscrewed from them, at least as long as the teeth of the locking teeth and the locking teeth are engaged.
  • the ratchet teeth Due to the sawtooth shape of the teeth, the ratchet teeth automatically snap into the various ratchet teeth when the fastener rotates, since the ratchet teeth are pretensioned in the direction of the ratchet teeth.
  • the pressing force and thus the radial sealing force and possibly also the axial sealing force increase successively when the locking toothing engages in the different locking stages of the locking toothing when the fastening element rotates.
  • the latching connection between the locking teeth and the latching teeth can be released.
  • the locking teeth can be biased via a Spannvor direction.
  • the tensioning device can be be preloaded and designed as a spring pawl. An additional spring element is then not necessary.
  • the Spannvor direction can have a handle in the form of an unlocking pin, via which the locking teeth can be moved against their biased position. The locking teeth and the locking teeth can be disengaged.
  • the connection of the reverse rotation lock with the fastening element can be released manually.
  • the handle or the unlocking pin can protrude in the radial direction so that it is easy to reach.
  • the two pressing areas of the fastening element are arranged so that they are spaced apart from one another in such a way that they form a particularly annular receiving space.
  • the two press areas can be arranged concentrically to one another.
  • the receiving space can serve to accommodate the locking teeth. If the two fasteners are connected to each other, the locking teeth can lie in the receiving space. The locking toothing can protrude laterally into the receiving space.
  • the anti-rotation lock it has proven to be advantageous if it has a bearing bush for mounting the threaded pin.
  • the bearing bush can be designed in the manner of a hollow cylinder.
  • the bearing bush can be inserted into a bore in the closing element and can be used to guide the threaded pin, so that it does not become jammed in the bore of the closing element during rotation.
  • the bearing bush can have a particularly circumferential insertion bevel, which facilitates the assembly or insertion of the bearing bush into the bore of the closing element. It is advantageous if the outer dimensions of the bearing bush match the diameter of the bore.
  • the recess can extend through the bearing bush, so that the bearing bush se, in particular over the entire surface, rests on the threaded pin.
  • the anti-rotation lock With regard to the manufacture of the anti-rotation lock, it has proven to be particularly advantageous if it is designed as a multi-component plastic part, in particular as a two-component plastic part, a first plastic component forming the sealing area and a hardened second plastic component forming the remaining areas of the anti-rotation lock.
  • Corresponding plastic parts are inexpensive to manufacture in a series production.
  • the softer sealing component can deform comparatively easily when subjected to force, which leads to a reliable seal.
  • the harder plastic component can give the anti-rotation device the required stability.
  • the locking teeth, the bearing bush and a ring area surrounding the sealing area on the circumference can be made of the harder plastic component.
  • the fastening element With regard to the production of the fastening element, it has proven to be advantageous if it is produced by a multi-component injection molding process, in particular by a two-component injection molding process.
  • This process enables the reverse rotation lock to be produced in a single process step, although the reverse rotation lock consists of two different materials. In this way, inexpensive and quick manufacture of the reverse rotation lock is achieved.
  • the fastening element it has proven to be advantageous if it has a threaded hole for screwing onto the threaded pin.
  • the threaded bore can be round and extend centrally through the fastening element.
  • the diameter of the threaded hole can correspond to the maximum diameter of the threaded pin, so that the fastening element can be screwed onto the threaded pin.
  • the internal thread of the threaded hole can match the external thread of the threaded pin.
  • the fastening element has a handling area arranged on the circumference, via which the fastening element is moved manually and can be screwed onto the threaded pin. The fastening element can be tightened by hand over the handling area.
  • the handling area can be corrugated on the circumference, which facilitates rotation by hand.
  • the handling area can be connected to the second pressing area. Furthermore, it is advantageous if the handling area in the connected state covers the latching toothing or the latching ring of the anti-rotation device in the manner of a cap. When connected, the locking teeth are therefore not visible from the outside and protected against external influences and dirt.
  • a closure actuation for actuating a closure element, in particular a sash tongue, with a threaded pin and a fastening device for fastening the threaded pin to a closing element is proposed, the fastening device being designed in the manner described above.
  • the closure element In order to move the closure element and thus to lock or unlock the closure element, the closure element can be moved via the closure actuation.
  • the closure actuation can thus serve as a drive for the closure element.
  • the closure element can be opened the threaded pin can be plugged on and rotatably coupled to it. It is advantageous if the closure element has a recess which is adapted to the geometry of the threaded pin, so that a positive rotational coupling between the threaded pin and the closure element is made possible.
  • the recess of the closure element can coincide with the recess in the anti-rotation lock.
  • fastening device is independent of the actuating element.
  • fastening device is not connected to the actuating device. This enables the threaded pin to be fastened independently of the thickness of the closing element or the door.
  • a closing element in particular a door, with an actuating element, a closing element, in particular a sash tongue, and a closure actuation is proposed, the closure actuation being designed in the manner described above and a threaded pin and a Fastening device includes.

  • FIG. 1 shows a perspective view of a section of a closing element 3 designed as a door.
  • the door 3 has a bore 3.6 through which a threaded pin 2 designed as a square threaded pin extends from the outside of the door 3.2 to the inside of the door 3.1 extends to adjacent interior.
  • An actuating element 3.4 is arranged on the outside of the door 3.2, which, however, cannot be seen in FIG. 1 due to the viewing direction.
  • the square grub screw 2 can be rotated about its longitudinal axis via the actuating element 3.4.
  • a locking element 3.5 configured as a sash tongue is arranged, via which the door 3 can be locked or unlocked. In the locked position, the sash tongue 3.5 engages behind an undercut, not shown, for example, and thus ensures that the door 3 can no longer be opened.
  • the sash tongue 3.5 To open the door 3 again, the sash tongue 3.5 must first be moved out of the undercut again, for which the square thread pin 2 is rotated via the actuating element 3.4. Due to the non-circular design of the setscrew 2, it is possible to mount the serrated tongue 3.5 very easily on the setscrew 2. This is because the sash tongue 3.5 basically only has to be secured against axial movement, since this is rotationally coupled to the set screw 2 due to the cross-sectional shape thereof. Before the friction tongue 3.5 is therefore in the axial direction on the square screw pin 2 can be plugged, but not relative to the square screw 2 rotating bar. 3, both the actuation element 3.4 not shown in FIG. 1 and the sash tongue 3.5 can be seen.
  • the square grub screw 2 and the fastening device 1 together form a lock actuation 7 for the sash tongue 3.5.
  • the square grub screw 2 is set via the actuating element 3.4 such that the square grub screw 2 cannot be pulled into the interior.
  • the actuating element 3.4 does not secure the square threaded pin 2 against axial movement in the direction of the outside of the door 3.2 or in the direction of the outside. For this reason it is necessary to secure the square grub screw 2 on the inside of the door 3.1 in the axial direction.
  • the square grub screw 2 is secured by the fastening device 1 in such a way that it can no longer be moved in the axial direction.
  • the fastening device 1 consists essentially of two individual elements, namely an anti-rotation device 4 and a fastening element 5.
  • the anti-rotation device 4 is first pushed in the axial direction over the square set screw 2 until it rests on the inside of door 3.1.
  • the fastening element ment 5 screwed onto the square grub screw 2. Since the reverse rotation safety device 4 and the fastening element 5 are independent of the actuating element 3.4 arranged on the opposite side of the door 3, it is possible to fasten with the fastening device 1 set screws 2, regardless of the thickness of the door 3, or to it secure this axially.
  • the anti-rotation lock 4 has a square recess 4.2 which is adapted to the size of the square threaded pin 2. Therefore, the reverse rotation lock 4 can be slid onto the square grub screw 2, but not rotatable relative to it, but pelt with it. With a movement of the square pin 2, the reminddusiche tion 4 rotates due to the positive connection in the direction of rotation therefore together with the square grub screw. 2
  • the fastening element 5 has a threaded bore 5.6, via which it can be screwed onto the square grub screw 2.
  • the fastening element 5 is thus not axially slidable onto the square grub screw 2, but can only be screwed onto it in the manner of a nut. If the anti-rotation device 4 is plugged onto the square grub screw 2 and the fastening element 5 has been screwed up far enough onto the square grub screw 2, the anti-rotation device 4 latches with the fastening element 5, which he will explain in more detail below with reference to the further figures. If the two elements 4, 5 are locked together, they can no longer be moved relative to one another.
  • the anti-rotation lock 4 is not rotatable on the square grub screw 2, this prevents that the fastening element 5 can be rotated. Furthermore, the fastening element 5, since it can only be rotated, but cannot be moved purely axially, prevents the anti-rotation device 4 from being moved axially. In this verbun shown in FIG. 1 and also in FIG. 6, the position of the square grub screw 2 can continue via the Actuating element 3.4 can be rotated about its longitudinal axis, but can no longer be moved in the axial direction. In this connected position, the anti-rotation device 4 is arranged between the closing element 3 and the fastening element 5.

If the fastening element 5 is screwed onto the square grub screw 2, the locking teeth 4.4 plunge into the receiving space 4.7 at a certain point, so that the locking teeth 4.4 and the locking teeth 5.1 come into engagement with one another. At a further rotation of the fastening element 5 in the screwing-on direction A, the locking toothing 5.1 is moved counter to its pretensioning, so that it gradually engages a ratchet in the various locking teeth of the locking toothing 4.4. Because of the sawtooth-shaped contour of the teeth, it is then no longer possible to turn the fastening device 5 counter to the screwing-on direction A, since such a movement is blocked. The anti-rotation device 4 and the fastening element 5 are then connected to one another in a form-fitting manner at least in one direction of rotation.
  • fastening element 5 is turned further in unscrewing direction A, at least until it has reached the end position shown in FIGS. 3a and 3b.
  • the fastening element 5 and the anti-rotation lock 4 can then no longer be removed from the square grub screw 2 and the square grub screw 2 is secured in the axial direction and the interior sealed.
  • connection of the teeth In order to loosen the fasteners 5 from the anti-rotation lock 4, the connection of the teeth must first be removed.
  • the locking toothing 5.1 can be moved against its bias, so that it and the locking toothing 4.4 come out of engagement.
  • the tensioning device 5.2 pretensioning the locking toothing 5.1 has an unlocking pin for releasing the connection. This protrudes in the radial direction over the contour of the fastening element 5, as can be seen in the representations of FIGS. 5a and 6.
  • the unlocking pin against the pretension By a movement of the unlocking pin against the pretension, the locking teeth of the locking teeth 5.1 can then be pulled out of the locking teeth of the locking teeth 4.4 and the positive connection between the anti-rotation device 4 and the fastening element 5 can be canceled. Only then is it possible to unscrew the fastening element 5 from the square threaded pin 2 against the screwing-on direction A.
  • the anti-rotation device 4 can then be removed from the square grub screw 2 and, in a next step, the square grub screw is pushed towards the outside of the door 3.2 and thus released from the door 3.
