Definitions

  • the invention relates to a drive for a wing of a door or the like. According to the preamble of claim 1.
  • a door closer with holding device in the cylindrical housing, a piston is movable in a sealed manner, wherein the piston is connected by the usual means to a door.
  • a spring biases the piston toward one end of the housing.
  • an actuating rod of a shuttle valve extends into the housing, which then engages the end face of the piston as it approaches the end of the housing.
  • the shuttle valve selectively directs a hydraulic fluid through closing and flow control valves.
  • the assembly further includes a solenoid actuated spool that blocks the return flow of the hydraulic fluid to keep the door open.
  • the disadvantage is an adjustment of the switching point of the valve is not possible. Likewise, influencing the control of the door closer at different door opening angles by means of the valve is not possible.
  • the invention has for its object to form a valve whose switching point is adjustable to control the drive.
  • Drives for wings of doors, windows or the like have arranged in a receiving space of a housing of the drive transmission, which with an output shaft and a lever arm for opening and closing the wing cooperates.
  • a piston cooperating with the gear is slidably disposed, wherein flow channels for the hydraulic fluid are provided in the housing, in which valves for controlling the behavior of the drive are arranged in a known manner.
  • a flow channel designed as a switching valve valve is arranged.
  • the switching valve in this case has a valve housing, by means of which the switching valve is received transversely to the direction of displacement of the piston adjustable in the housing.
  • a valve body is arranged with a valve stem, which protrudes for actuation of the switching valve by the piston transversely to the direction of displacement of the piston into the receiving space.
  • the drive can be designed as a hydraulic door closer and be provided for overlying mounting on a wing of the door or the frame or for integrated mounting, for example in the wing.
  • the drive may have a closing spring as an energy storage, which is tensioned when opening the wing via a lever arm and arranged in the drive, formed by means of a Hubkurvenin or a toothed piston gear.
  • the drive can also be designed as an electro-hydraulic, automatic drive with and without closing spring.
  • the drive can of course also be designed for installation in the floor as a floor door closer.
  • the drive may comprise one or more pistons, for example a working piston which is coupled to the gear or which is toothed and together with a pinion forms the gear on which the closing spring acts and / or a damping piston which controls the movement dampens the wing connected to the drive.
  • the proposed switching valve of the drive can cooperate depending on the desired behavior with one of the pistons.
  • several switching valves can be provided in the drive, wherein these can be actuated by different pistons or by the same piston.
  • a drive 1 for a door or the like is shown.
  • the drive 1 shown here by way of example is designed as a door closer and suitable for installation in a wing of a door.
  • the drive 1 has a housing 2 with mutually arranged mounting tabs 3, by means of which the drive 1 in the wing of the door can be fixed.
  • the drive 1 has an output shaft 4 for connecting a lever arm, which can be performed for transmitting power to the frame of the door in a slide, as it is known per se and not shown here.
  • the drive 1 may be formed in another embodiment for overlying mounting on the wing or the frame or for installation in the floor as a floor spring.
  • a closing spring 9 is arranged, which cooperates with a working piston 10.1.
  • the working piston 10.1 forms with a non-rotatably connected to the output shaft 4 cam plate 11 a gear-be to translate and transmit the rotational movement of the output shaft 4 in a sliding movement of the working piston 10.1.
  • the output shaft 4 and thus the cam disk 11 is rotated by the lever arm, whereby the working piston 10.1 is moved against the closing spring 9.
  • the force of the compressed closing spring 9 is then to close the wing available, the cam slide 11 and thus the output shaft 4 rotates back during the closing operation of the working piston 10.1, whereby the wing is acted upon by the lever arm in the closing direction.
  • the end of the receiving space is closed with a closure lid 12.
  • a damping piston 10.2 is further arranged, which also cooperates with the cam 11.
  • the drive 1 in a known manner also have a gear which is formed with a toothed piston and an output shaft 4 which is provided with a pinion, wherein the toothed piston combines the function of working piston 10.1 and damping piston 10.2.
  • the piston position is therefore directly related to the opening angle of the wing.
  • At least one flow channel 13 is arranged in the wall of the housing 2 of the drive 1, which opens into the receiving space, as in the FIGS. 3 to 5 for the switching valve 6 described in detail below.

  • the throttle valves 5 are in flow channels 13, which open into the receiving space and are closed or released here by the lateral surface of the piston 10.
  • the optionally arranged in the drive 1 solenoid valve 7, which is connectable via terminals 8, can serve to determine the drive 1 in an open position of the wing of the door, as is common for fire doors.
  • a switching valve 6 is shown as a single part in section.
  • the switching valve 6 comprises a valve housing 14 with a valve interior 15 for a valve body 16 and a valve spring 17.
  • the valve interior 15 is at one end with a closure element 18, on which the valve spring 17 is supported, sealed.
  • the valve spring 17 is supported on a collar 19 of the valve body 16, which is provided by a reduction in the diameter of the valve body 16 in the region of the valve spring 17, in the valve spring 17 engaging spring guide 20 is formed.
  • the collar 19 also serves to guide the valve body 16 in the valve housing 14.
  • the valve body 16 also has a valve stem 21, which corresponds to an associated valve seat 22 in the valve housing 14.
  • a shaft seal 23 may be provided, which sealingly rests on the valve seat 22 when the switching valve 6 is closed and can be arranged in a groove in the valve stem 21.
  • the valve stem 21 merges into a valve tappet 24, which passes through a valve bore 25 arranged in the valve housing 14.
  • the valve stem 24 may be significantly smaller in diameter than the valve bore 25 or at least partially reduced, for example flattened, in order to allow a sufficient volume flow of hydraulic fluid through the valve bore 25 in the open position of the switching valve 6.
  • the valve housing 14 is provided with a transverse bore 26, which corresponds to the flow channel 13 of the recorded in a stepped bore 27 in the housing 2 switching valve 6, as shown in the FIGS.
  • valve 3 to 5 is shown, which show the interaction with a piston 10 and the arrangement in the housing 2 with a flow channel 13 shown schematically.
  • a throttle valve 5 is further arranged by way of example.
  • the switching valve 6, the flow passage 13 interrupts or connects depending on the position of the valve stem 24, wherein the protruding into the receiving space valve stem 24 may have no connection to the flow channel 13 and in contrast may be sealed.
  • the valve housing 14 is provided with an inner seal 28 and an outer seal 29.
  • the inner seal 28 seals the receiving space of the housing 2 to the flow channel 13 and the stepped bore 27 opening into the receiving space, while the outer seal 29 seals the flow passage 13 to the outside in order to prevent the escape of hydraulic fluid from the drive 1.
  • the narrower portion of the stepped bore 27 may have an extension 31 in order to compensate for the changing of the transverse bore 26 by adjusting the switching valve 6 with respect to the flow channel 13 both horizontally and vertically.
  • the valve housing 14 may be tapered in this area or have on the periphery a number of advantageously horizontally offset transverse bores 26, which are arranged so that there is always a connection to the flow channel 13.
  • a thread is provided in the stepped bore 26, which corresponds to a thread on the valve housing 15, which is disposed between the region of the inner seal 28 and the region of the outer seal 29, wherein the sealing regions in both the stepped bore 26 as also remain thread-free on the valve housing 14 to ensure optimum sealing.
  • a tool holder for engagement of a tool such as a screwdriver, provided, with which the switching valve 6 is adjustable in its position in the stepped bore 27 along the thread by turning.
  • the switching point of the switching valve 6 can be determined by the position of the arranged in the valve housing 14 valve seat 22 with respect to the in the receiving space transversely to the direction of actuation of the switching valve 6 slidably disposed piston 10, which acts on the valve stem 24 for actuating the switching valve 6, is variable.

  • a more or less strong displacement movement of the valve stem 24 may be rotationally symmetrical as Kegelstupf on the piston 10 or only partially, in which case a rotation of the piston 10 must be prevented.
  • the piston 10 is shown in various positions in the receiving space, wherein the chamfer 30 each having the same inclination.
  • the switching valve 6 is shown in a first setting, which is determined by the position of the switching valve 6 in the stepped bore 27.
  • Fig. 3 is the switching valve 6 in the illustrated position of the piston 10 just at the switching point and closed, whereby the lying in the course of the flow channel 13 throttle valve 5 is effective, the throttle valve 5 is a sliding movement of the piston 10 - in the Fig. 3 to the left - dampened by limiting hydraulic fluid flow.
  • the chamfer 30 is shifted depending on the position and direction of movement of the piston 10 so that the valve stem 24 is still or just, depending on the direction of movement of the piston 10, in abutment with the inclined surface 30.
  • a displacement of the piston 10 in the Fig. 3 to the right causes a lifting of the valve stem 24 against the valve spring 17 and lifting the stem seal 23 from its valve seat 22, whereby the switching valve 6 opens.

  • the arranged in the further course of the flow channel 13 throttle valve 5, which also opens into the space on the left side of the piston is thereby bridged by the switching valve 6, whereby no damping of the piston movement takes place through the throttle valve 5.
  • Fig. 5 the switching valve 6 is shown in a different setting, wherein the switching valve 6 is not screwed so far into the stepped bore 27, whereby the valve stem 24 protrudes less into the receiving space in the drive 1.
  • the valve stem 24 is just in contact with the chamfer 30 of the piston 10 and thus also at the switching point.
  • the piston 10 is opposite to the position in Fig. 3 further to the right in the recording room.
