Definitions

  • the invention relates to a slide rail door closer with holding device for driving and holding the closing movement of a hinged door leaf in an open position, as well as a two-leaf swing door which is equipped therewith.
  • the active leaf when the inactive leaf is open, the active leaf also open, for example driven by a spring or hydraulics, executes a closing movement leading the inactive leaf, this closing movement is stopped by the action of the closing sequence control device at a certain opening angle until the inactive leaf in its closing movement, the power wing is sufficiently far ahead that it ensures the correct closing sequence.
  • a swivel arm projects from a drive unit attached to the door leaf is.
  • the slide rail is arranged on the upper frame part of the door frame and aligned parallel thereto. With the door closed, that end of the pivot arm which is attached to the door leaf is closer to the pivot axis of the door leaf than that end of the pivot arm which is connected to the sliding block.
  • the attached to the door drive unit exerts on the swivel arm held pivotally on her in the same direction to the opening pivot movement of the door aligned torque.
  • the reaction torque acting on the drive and thus on the door leaf from the swivel arm drives the door leaf to be closed in the absence of other moments.
  • the sliding block slides in the slide rail away from the axis of rotation of the door leaf.
  • the swinging arm of the inactive leaf abuts an extension which protrudes radially from a rod arranged in the sliding rail so that the rod, which is aligned parallel to the sliding rail, is also rotated about its longitudinal axis.
  • the rod brings a locking part out of the path of movement of the sliding block of the active leaf rigidly anchored part, so that thus closing movement of the active leaf is released.
  • the EP 2 208 846 A2 proposes several embodiments of closing sequence controls in which the pivotal movement of the pivoting arm relative to the slide rail in translation of parts is translated parallel to the slide rail longitudinal direction. This is done to compensate for that linear movement of the sliding arm belonging to the sliding block, which runs during the last part of the closing movement of a door leaf to the axis of the door leaf and not away from it.
  • the said parts are kept movably guided on the sliding block. It is further proposed by blocking movement of these parts to block pivotability of a swing arm.
  • a holding device comprising a fluid cylinder and at least one valve controlling the fluid cylinder, wherein at least the fluid cylinder is arranged in the slide, there against pivoting movement with the Swivel arm of the active leaf is supported, and optionally acts on the swing arm of the active leaf.
  • fluid cylinder in this document is meant a drive unit comprising a cylinder body and a piston moveable therefrom and a fluid (liquid or gas) and, depending on the embodiment, usually referred to as either “hydraulic cylinder” or "pneumatic cylinder” becomes.
  • cylinder body which of the two movable parts of the fluid cylinder is referred to as “cylinder body” and which is referred to as “piston” depends on which of the two parts is perceived as moving more than the other part.
  • the less moving perceived part is referred to as a "cylinder body”, which is considered more moved parts than “piston”.
  • the fluid cylinder is attached to the sliding block and mitbewegbar with its sliding movement along the slide rail. Contrary to expectations, this results in simpler construction conditions, as if the fluid cylinder in the slide would not be longitudinally displaceable.
  • the movable part (piston) of the fluid cylinder projects into the path of movement of a part which is rigidly connected to the pivoting arm. Since the fluid cylinder thus acts on the pivoting arm by positive locking and not only by frictional engagement, a robustly functioning construction can be realized in which the level of the required braking or holding forces is permanently constant and predictable.
  • a cam which projects radially from the stub shaft mounted on the sliding arm of the swivel arm.
  • the door of Fig. 1 has a moving leaf 1 and a passive leaf 2.
  • the two wings overlap at the contact area, with respect to the opening direction of the active leaf 1 front. Therefore, from the closed state of both wings, the active leaf 1 must be opened in front of the inactive leaf 2, and when closing the passive leaf 2 must be closed in front of the active leaf 1.
  • the door of Fig. 1 is equipped with sliding rail door closers mounted on the hinge side.
  • Fig. 1 are of these for both doors 1, 2 common slide 3, the gangway-side pivot arm 4, the gang-wing-side drive unit 5, the stand-wing-side pivot arm 6 and the stand-wing-side drive unit 7 can be seen.
  • "Band mutual mounting” means that the pivot axes of the door leaves 1, 2 are not on the same side of the levels of the door leaves 1, 2 as the drive units 5, 6 but on the opposite side of these levels. In this type of mounting, which is common especially when swung outwardly outward doors, the sliding direction of a sliding block during the closing pivotal movement of a door wing even at a relatively large opening angle of the door to turn.
  • the slide 3 is stationary fixed in the horizontal direction at the upper, horizontally extending portion of the door frame attached.
  • the drive units 5, 7 are on the door wings 1, 2 attached.
  • a pivot arm 4, 6 projects in each case a sliding block, which is held longitudinally displaceably mounted in the slide rail 3.
  • the pivot arms 4, 6 are pivotable in horizontal planes; when the door panels 1, 2 closed, they are aligned approximately parallel to the door plane, wherein the sliding-stone-side end of each pivot arm 4, 6 is further away from the pivot axis 8 of the respective associated door leaf 1, 2 than that end which is located on the drive unit 5, 7 , Closing movements of the door leaves 1, 2 are driven by the drive units 5, 7, by exerting on the respective associated pivot arm 4, 6 a torque which "seeks" the pivot arm so that it is parallel to the plane of the associated door leaf 1, 2 is aligned.
  • the slide 3 is approximately a U-profile with downwardly open cross-sectional area.
  • the gangway-side sliding block 9 is held longitudinally displaceable.
  • the gangway-side pivot arm 4 is pivotally supported.
  • the sliding block 9 in the outlined advantageous embodiment, the function of the housing of the holding device 8.
  • the sliding block 9 has about in the form of an elongated piece of hollow profile whose profile direction parallel is aligned with the slide rail 3 and with its profile walls comprises an elongated cavity 10 aligned parallel to the slide rail direction.
  • the cross-sectional area of the elongated cavity 10 is circular.
  • a stub shaft 11 rigidly connected to the pivoting arm 4 projects through a bore on the underside of the sliding block 9 into the oblong cavity 10 aligned parallel to the slide rail direction.
  • the pistons 13, 14 of two fluid cylinders are arranged, which are aligned parallel to the slide rail 3 and opposite to each other.
  • the cylinder cavities 15, 16 belonging to the pistons 13, 14 are delimited on their lateral surface by lateral surface sections of the cavity 10.
  • the "fixed" part of the fluid cylinder is thus formed in each case by the sliding block 9 itself.
  • the fluid cylinders are designed as hydraulic cylinders; in the cylinder cavities 15, 16 is therefore oil 17 as working fluid.
  • the two cylinder cavities 15, 16 are connected by a connecting channel 20, so that in them the same static oil pressure prevails.
  • the cylinder cavity 15 is sealed at the opposite end of the piston 13 by a sealing in the cavity 10 of the sliding block 9 anchored support member 21.
  • the cylinder cavity 16 is sealed at the opposite end of the piston 14 by a valve block 22, which is also anchored sealingly in the cavity 10 of the sliding block 9.
  • valve block 22 passes through the valve block 22 through several channels connecting the cylinder cavity 16 on one side with the fluid container 24 on the other side, wherein in the channels valves 25, 27, 28 are used.
  • the control valve 25 has an actuating part 26 which protrudes from a valve sleeve in the absence of other forces due to the action of a compression spring. In this state - the in Fig. 3 is outlined - the control valve 25 is locked. When the actuating member 26 is pressed into the valve sleeve, the control valve 25 is switched to flow so that oil 17 is free between the cylinder cavity 16 (which is constantly with the cylinder cavity 15 is connected) and the fluid container 24 can flow back and forth.
  • the check valve 27 allows flow from the fluid reservoir 24 into the cylinder cavity 16 unhindered, but blocks oppositely directed flow.
  • the pressure relief valve 28 allows flow from the cylinder cavity 16 into the fluid reservoir 24 when the pressure in the cylinder cavity 16 is higher by a defined threshold than in the fluid reservoir 24. Flow in the opposite direction is not possible through the pressure relief valve 28. (Of course, there is the possibility to use instead of three valves with only one function and a smaller number of valves, which then have more than one function.)
  • the closing movement of the active leaf 1 causes a movement of the swing arm 4 consequently the sliding block 9 and thus the whole Holding device 8 is moved along the slide rail 3 and the stub shaft 11 and with this the cam 12 are rotated about the axis of the stub shaft 11 relative to the sliding block 9.
  • a cam 12 presses on in each case one end face 18, 19 of a piston 13, 14. If the inactive leaf 2 is closed, the actuating part 26 is pressed - the mechanism is explained below - so that the control valve 25 is opened and oil 17 can flow unimpeded from the cylinder cavity 16 into the fluid container 24.
  • the pistons 13, 14 are pushed back against the action of the springs 23, wherein oil 17 is forced into the fluid container 24.
  • the pivoting movement of the swing arm 4 and thus the closing movement of the active leaf 1 is only slightly damped, but not blocked, so that the active leaf can close completely.
  • the cams 12 are moved so that the pistons 13, 14 get more space and extend due to the springs 23.
  • Oil 17 can be independent of the position of the control valve 25 flow freely from the fluid container 24 into the cylinder cavities 15, 16, since the check valve 27 always passes in this direction.
  • air can flow in through the channel 29. (One could also do without channel 29 and instead provide an air cushion, which is elastically compressible, in the fluid container 24.)
  • the opening of the extending over the control valve 25 channel is very high, the cylinder cavity 16 is vented automatically during operation.
  • the inactive leaf 2 is opened, due to the overlap of the door and usually also due to a driving lever, which projects from the inactive leaf 2 to the active leaf 1, the active leaf forcibly in taken an opening movement.
  • the operating part 26 can extend - the mechanics will be explained below - and the control valve 25 is closed.
  • oil 17 can nevertheless flow from the fluid container 24 into the cylinder cavities 15, 16 through the check valve 27 so that the pistons 13, 14 can extend and during the first part of the opening movement of the active leaf 1 with their curved end faces 18, 19 stay in contact with the cam 12.
  • the active leaf 1 In the case of the opening movement of the active leaf 1 driven by the opening of the inactive leaf 2, the active leaf 1 thus remains in an open waiting position after it has come out of contact with the inactive leaf 2 already after an extremely short return spring travel. Thus, it is sufficient if the active leaf 1 is forcibly co-opened during the opening movement of the passive leaf 2 only a very small piece.
  • the active leaf 1 is prevented from further closing movement until either the control valve 25 is actuated - which means that the inactive leaf 2 has been closed - or until the pressure relief valve 28 responds.
  • the pressure relief valve 28 is responsible for the overload behavior and adjusted accordingly. It speaks, for example, when trying to open the active leaf 2, the power wing 1 to close by force by pressing them manually with great force in the closing direction.
  • the active leaf 1 is fully opened and then released when the fixed leaf 2 is open, the active leaf 1 is only driven by the drive unit 5 to accelerate the closing movement. After some movement meet the according to the closing movement of the active leaf pivoted cam 12 to the extended piston 13, 14. This meeting between cam 12 and piston 13, 14 takes place at a much larger opening angle of the active leaf 1, than that angle at which the active leaf. 1 must necessarily stand still so that the passive leaf 2 can still be closed past him.
  • the cams 12 press with very great force against the pistons 13, 14, so that they are forcibly pushed back.
  • oil 17 through the pressure relief valve 28 passes through the cylinder cavities 15, 16 pressed into the fluid container 24.
  • the kinetic energy of the active leaf 1 is reduced by the flow of oil in the pressure relief valve 28.
  • the active leaf is slowed down to the timely style level gently, vibration-free and noiseless or very quiet controlled. This is done without causing any annoying fretting on any part.
  • Fig. 4 shows a view with the slide rail 3 parallel viewing direction on the side of the fluid container 24 of the holding device 8.
  • the housing of the holding device 8 is formed by the sliding block 9.
  • the roughly U-shaped slide rail profile on the outer side of the two lateral limbs in each case two surface regions 31, which are facing away from the respective lateral outer surface, so that the horizontal component of its surface normal vector (which points from the surface into the environment and not in the material of the slide in) is aligned towards the center of the cross-sectional area of the slide rail profile 3 out.
  • the slide rail 3 also at its central longitudinal portions with a holder on the wall to which it is attached, to hook so that they at this Mount against movement away from the wall is positively held.

  • the sliding block 9 abuts against the surfaces 30 with a counter-oriented surface.
  • a Verhakung is formed, which causes the ends of the two legs of the slide rail profile are not bent away from each other, since they are forcibly held by the sliding block 9 at the same distance from each other.
  • Two elongated, parallel to the slide 3 aligned release strips 32, 33 are horizontal in the slide 3, ie parallel to the groove base of the groove formed by the slide rail profile displaced. For this they lie in the sliding rails 3 between the groove base and in each case one of the two intermediate walls 34, which project from one of the two side walls of the slide rail profile.
