Definitions

  • the invention relates to a drive for a wing of a door or a window according to the preamble of claim 1 and claim 16.
  • a door closer which has a housing filled with a liquid.
  • the housing may consist of an oil-tight plastic and is guided via a dovetail-shaped fastening part on a mounting plate to be fastened to the door displaceable and lockable by screws.
  • the plastic housing has high wall thicknesses in order to support the forces occurring at and in the door closer can.
  • a dimensionally accurate production is made more difficult with non-cutting methods, since plastics, for example, shrink when they are manufactured by injection molding on cooling.
  • plastics can flow away with a force in the event of continuous application, as a result of which the dimensions of the housing change.
  • the plastic housing of the door closer would melt in case of fire due to the effect of heat and the door closer could not hold the door.
  • a door closer is known with a Hubkurvenin which is connected to an emerging from a filled with a damping medium housing drive shaft.
  • the Hubkurvenin is seen in the axial direction on each side of a pinch roller and is in operative engagement with a piston acted upon by a closing spring.
  • the piston and the housing are made of an oil-tight plastic, wherein the piston is a socket or having a piston ring of a different material.
  • the piston enclosing bore may also have a bush made of a different material.
  • the disadvantage is that properties of plastics, such as their sliding properties, can not be used because the piston to increase the life of a bush or a piston ring of a material other than plastic encloses, and the piston receiving space is also made of a different material. Due to the large material thicknesses of the plastic in the piston and the housing large shrinkage, which adversely affect the dimensional accuracy and thus the accuracy of fit of the piston and housing.
  • the WO 95/20090 A shows a door closer with a guided in a door closer housing and a closing mechanism with a rotatable closer shaft when opening the associated door leaf against a restoring force sliding lock piston.
  • the closer shaft is connected to a arranged between the door and the fixed door frame actuator for power transmission between the door leaf and the door frame and a in the door closer housing with the closing piston in the same direction shifted damping piston, which consists of plastic, wherein a non-forming toothing insert made of metal between the Closing and the damping piston is provided.
  • a door closer is known, with a door closer housing and a guided therein and displaceable by means of a door closer gear Piston assembly, which has a closing piston, one of which in the direction of displacement spaced damping piston and arranged between the closing and the damping piston piston intermediate piece with a transmission element of the door closer transmission and a support member for this purpose.
  • the closing and the damping piston is made of plastic and the non-forming, designed as a toothed insert piston intermediate piece is made of metal and embedded in the end closing and the damping piston.
  • the invention has for its object to provide a cost-effective drive for the wing of a door or a window using plastic, with a housing and / or a piston, which are dimensionally stable and stable.
  • An inventive drive can be designed as an automatic drive for doors or windows.
  • the drive can also be a manual window operator or a floor or overhead door closer.
  • overhead door closers are connected via a linkage to the wing of the door closer associated door.
  • This linkage transmits the rotational movement of the wing to a shaft in the door closer, which shifts, for example via a toothing or a Hubkurvenement a acted upon by a spring piston.
  • This displacement movement takes place within a hydraulic fluid in the housing, wherein the hydraulic fluid can flow from one side of the piston to the other side by overflow and valves.
  • Throttle valves are usually arranged in the overflow channels, with which the behavior of the door closer can be adjusted. Opening the sash moves the piston in the door closer so that the spring is tensioned. By relaxing the spring, the piston is moved back and the shaft is rotated back, whereby the wing is guided over the linkage in its closed position. The forces occurring must be supported by the housing and the piston.
  • an insert which is at least partially coated with plastic, for example by an injection molding process ,
  • the insert is shaped to stiffen all required areas of the drive housing.
  • a dome is formed on both sides in the region of the closer shaft, which can support the bearing of the shaft.
  • On the side opposite the piston of the spring bent projections are provided on the insert, which can support the spring force of the tensioned spring. Embossing or beading can further stiffen the insert.
  • fastening tabs are formed, which allow to secure the drive to the door or in a bottom housing.
  • the attachment tabs can be encapsulated with plastic or kept free. It is also advantageous that, for example, threads can be present in the insert for attachment, which has a higher strength than threads in the insert Plastic have. According to the invention the insert is provided with recesses, which favor a flow around plastic.
  • the piston of the drive is also manufactured using an insert, whereby a housing adapted piston can be formed.
  • the teeth for the closer shaft can be formed with or inserted into the insert part of the piston and fixed thereto.
  • recordings may be provided for valves. Possible ribbing and recesses may favor the application of plastic and increase the strength of the insert.
  • the material thickness of the plastic can be kept small without losing the advantages of the plastic.
  • the housing dimensions can thus also be kept very small, with different housing shapes, in particular in the piston chamber can be formed, which allow a small size of the door closer.
  • the piston chamber deviating from the usual round shape may be rectangular or polygonal, whereby a rotation of the piston is achieved.
  • the edges of the piston can be rounded.
  • the properties of the plastic can be used, and it is a cost-effective production without complex mechanical processing possible.
  • the insert may be formed of metal as a stamped and bent part, whereby a favorable production is achieved. However, it can also be produced with other manufacturing processes, such as internal high-pressure forming, whereby seamless inserts are possible. It is also conceivable to use other materials which meet the respective requirements, such as other plastics, if the advantages of the behavior in case of fire can be dispensed with. It is advantageous that in case of plastic inserts made in the form of very complex designs can be produced inexpensively.
  • the stamped and bent part after its final shape has been formed, can be joined together by folding over closure tabs, by riveting, screwing or else by soldering or welding. Also favorable is a latching in the manner of a toothing.
  • the insert can be one-piece or multi-part. Multi-part inserts can be fixed together.
  • the insert is to be provided with recesses, which favor a flow around plastic.
  • the piston tread made of plastic can be formed, with special sliding properties of the plastic can be used. In this case, both inside and outside parts of the plastic can be kept free.
  • the in Fig. 1 shown in longitudinal section door closer 1 has a housing 2 for receiving the piston 3, which cooperates with the shaft 4 and the spring 5.
  • the shaft 4 is actuated in a known manner via an arranged between the door leaf and the shaft 4 of the door closer 1 linkage.
  • the door closer 1 can by the energy stored in the spring 5, which pushes the piston 3 back to its original position, and via the shaft 4 and the rod guide the door back into its closed position.
  • the housing 2 has an insert 7 'through which the housing 2 is reinforced.
  • the insert 7 ' can be formed as a punched-bent part or stamped-stamped part, as in the FIGS. 2 and 3 is shown. However, it can also be produced with other manufacturing processes, such as internal high-pressure forming, whereby seamless inserts are possible.

It is advantageous that in case of plastic inserts made in the form of very complex designs can be produced inexpensively.
  • projections 10 'and embossments for receiving valves or seals may be provided.
  • the fasteners 6 for the housing 2 are likewise formed by tabs 8 formed on the insert part 7 '. This ensures that the attachment of the door closer 1 to a fire door can not melt even in heat, as could otherwise be the case with a mounting in plastic. Likewise, the piston 3 and the shaft 4 are held with their associated bearings in the insert 7 'of the housing 2 even after a melting of the plastic.
  • An insert 7 'or a multi-part insert 7' designed as a punched-bent part or a punched-stamped part can be brought together into its final shape after the punching and bending process, wherein the insert part can be locked in meandering latching lugs. Another possibility is fixation by bending, crimping, riveting, screwing or other fastening and joining methods.
  • the insert 7 'recesses 13 such as slots or holes, which improve circulation of the plastic around the insert or parts of the insert 7' around and the connection of the plastic with the insert, for example, the tabs 8 for fastening the door closer free can stay.
  • the insert 7 ' may have a round cross section or a non-circular shape, as in Fig. 3 represented, z. B. have an approximately rectangular or polygonal shape. The edges can be rounded.
  • the Indian Fig. 4 shown piston 3 has a shaping insert 7 "through which the piston 3 is reinforced.
  • the insert 7 may be formed as a stamped and bent part, as shown in the Fig. 4 is shown. In this case, all required areas of the piston 3 are amplified. In order to support the spring force acting on the piston 3 by the spring 5, "bent extensions 10" are provided at right angles to the extension direction of the insert 7.
  • the insert 7 can also be used with other manufacturing methods, as internal high-pressure forming processes, whereby seamless inserts are possible. Other materials can be used which meet the respective requirements, like other plastics. It is advantageous that in case of plastic inserts made in the form of very complex designs can be produced inexpensively.
