Definitions

  • the invention relates to a sectional door, the sections of which can be moved by means of at least one conveyor chain between an open position and a closed position in which the sections stand on one another, with a guide device with at least one guide rail section for receiving the sections at least in the closed position and with deflection means provided on the sections , each pivoting a first section located outside the guide rail section relative to an adjacent section received in the guide rail section so that the mutually opposite edges of these adjacent sections are separated from one another over their entire length.
  • the sections are clamped together in preferably vertical guide sections, which are in particular designed as rails, while in the open position they are hung behind one another in a magazine or behind a lintel or a panel.
  • the sectional door is opened or closed in such a way that sprockets move the conveyor chains carrying the sections up and down. If the sections hanging vertically on the conveyor chains reach the area of the chain wheels, they describe there on their way between closing and Open position a partial arc, so that they are guided by a deflection from the closed position into the magazine or from the magazine to the closed position.
  • a sectional door is known from DE 37 06 054 C1, in which the sections also have first bolts on both sides adjacent to their upper edge, which are connected to the conveyor chains, and second bolts on both sides adjacent to their lower edge.
  • control cams are formed in the planes defined by vertical guide rails and magazine rails, which extend from the magazine rails to the vertical guide rails. The distance of the transition regions defined by the vertical guide rails and the control cam from the chain deflection points of the chain wheels is not greater than the distance between the first and second bolts on the sections.
  • a disadvantage of the known sectional gates described above is that the sections in the region of the vertical guide rails must maintain a non-negligible minimum distance from one another during the movement of the sections in the guide rails. This is necessary because otherwise the sections would tilt against each other during the deflection via the chain wheels. Such tilting of the sections with one another can result in the destruction of the sections or the blocking of the upward movement of the sections within the vertical guide rails. This is particularly critical when using sections made of glass or similar sensitive materials. At the same time, however, there is a need that the sections can be moved within the vertical without an at least substantial mutual distance from one another. Safety requires, in particular with the automatic movement of the sectional doors, a very small to no mutual distance between the sections, since otherwise parts of the body such as fingers or feet could get caught between the individual sections.
  • the object of the invention is therefore to provide a sectional door of the type mentioned, in which the disadvantages mentioned above are avoided and which enables the sections to be pivoted between the open and closed positions in a simple, low-maintenance and therefore inexpensive and reliable manner.
  • the object is achieved according to the invention in a sectional door of the type mentioned at the outset in that the deflection means for pivoting the section can be acted upon by a transverse component of the tensile force of the conveyor chain.
  • the transverse component of the tensile force of the conveyor chain is advantageously used for pivoting the sections hanging on the conveyor chain.
  • the deflection means can be supported on the conveyor chain, as a result of which the weight of the section pushes it out of the course predetermined by the tensile force. This results in a direct transmission of power from the deflection means to the conveyor chain. At the same time, the deflection means is pivoted out by the counterforce caused by the pulling force of the conveyor chain. It is also achieved that the sections located within the guide rail section are drawn together by the conveyor chain, since the deflection of the conveyor chain from the course predetermined by the tensile force results in a quasi-shortening of the conveyor chain by the conveyor chain running around the deflection means within the guide rail section must and thus forms bulges, so that less conveyor chain length is available for connecting the individual sections.
  • the length of the conveyor chain or the deflection of the conveyor chain caused by the deflecting means is coordinated from the course predetermined by the tensile force in such a way that the sections within the guide rail section are spaced little to no distance from one another. This advantageously results in a dual function of the conveyor chain, on the one hand pivoting the section that is located outside the guide rail section relative to the adjacent section accommodated in the guide rail section, and on the other hand shortening the sections within the guide rail section to eliminate the mutual section Distance contracts.
  • the sections are expediently guided between their open position and their closed position via a deflection, in the direction of which the deflection means pivot the sections.
  • the deflection means preferably have a curved surface against which the conveyor chain lies in each case.
  • the conveyor chain can expediently lean against the deflection means over a certain length, as a result of which the conveyor chain is evenly loaded in the region of the deflection means.
  • the curved surface is provided with a smooth surface in order to ensure that the conveyor chain slides as smoothly as possible on the deflection means.
  • the deflection means are preferably designed as a lateral extension on the sections.
  • the solution according to the invention can be implemented in a practical and inexpensive manner, particularly in the case of sections suspended on the side of the conveyor chain.
  • the deflecting means like the fastening points of the conveyor chain, can be covered by the guide rail sections at least in the closed position of the sections, so that one obtains an optically clean side closure of the sections in the closed position.
  • the guide rail section is expediently essentially vertical and the sections are suspended from the conveyor chain by means of bolts provided at the fastening points.
  • the sections are advantageously movably suspended on the conveyor chain, which favors the pivoting of the sections.
  • the sections are particularly preferably provided on their sides with guide elements, by means of which the sections are accommodated at least in the guide rail section, as a result of which the sections are guided particularly reliably during the movement within the guide rail sections.
  • the sections have at least on one side two guide elements spaced apart in the direction of movement, preferably embodied as rollers, which run in the guide rail section, as a result of which the sections can be moved particularly easily and quietly within the guide rail section.
  • the guide rail section can be designed as a hollow profile and the roller diameter exactly match the clear inner width of the hollow profile, so that a particularly precise guidance of the sections within the guide rail section is ensured.
  • the guide device has an insertion section for inserting the sections, which is followed by the opening position end of the guide rail section and which is widened at least in the pivoting direction of the sections relative to the guide rail section.
  • the insertion section is connected in one piece to the guide rail section.
  • a harmonious transition from the insertion section into the guide rail section can be achieved within the guide device. This also contributes to a smooth process when opening or closing the sectional door.
  • the insertion section has a first part, of which at least one section forms a first bevel, and a second part, of which at least one section also forms a second bevel.
  • the beveled sections of the first and second, respectively Part of the insertion section is expediently arranged at such an angle to the guide rail section that they support a smooth and even transition from the pivoted position of the sections to the position in which the sections are one above the other.
  • the second bevel of the insertion section is particularly preferably arranged at a distance from the end of the guide rail section on the opening position.
  • the second part of the insertion section has a section which continues the guide rail section and is arranged between the second bevel and the end of the guide rail section on the opening position.
  • the distance between the two guide elements is the same for all sections and corresponds approximately to the distance between the bevels.
  • This coordinated dimensioning of the spacing of the guide elements and the spacing of the bevels takes into account the pivoting movement of the sections upon entry and exit into and from the insertion section, which enables a particularly smooth transition of the sections between the insertion section and the guide rail section.
  • the sections are advantageously guided synchronously with the pivoting movement from the bevels of the insertion section into the guide rail section.
  • the guide elements are preferably supported on the widened insertion section when the sections are introduced into the guide device, a first guide element arranged adjacent to the edge of the sections facing the closed position expediently being supported on the first bevel while the second section is being inserted, while the second adjacent is supported supports the guide element arranged on the edge of the section facing away from the closed position on the second bevel.
  • the distance between the end of the guide rail section on the opening position and the start of the deflection on the closing position is greater than the distance between the fastening points of the conveyor chain and the first guide elements on each section.
  • At least some of the sections advantageously consist of glass.
  • the sectional door according to the invention can thus also be used in an environment which is demanding from an aesthetic point of view.
  • the sections are arranged side by side in a magazine in the open position. This allows storage of the individual sections in the open position in a space-saving manner.
  • the sections in the magazine are moved by at least one second conveyor chain.
  • the sections advantageously hang in the magazine on at least one parking rail.
  • This parking rail which preferably runs essentially horizontally and on which the sections are supported by means of their bolts, ensures, like the guide rail section, that the sections are guided securely even in the open position of the sectional door, advantageously with the aid of a second conveyor chain.
  • the sectional door 1 shows a sectional door 1 in a side view.
  • the sectional door 1 has a guide device 8 and a magazine 10 arranged at right angles thereto, as well as several identical lamellar sections 4 which run within the guide device 8 and the magazine 10.
  • the magazine 10 is designed so that it can accommodate all sections 4 of the sectional door 1.
  • the sections 4 can be moved between a closed position I in the guide device 8 and an open position II in the magazine 10 with the aid of a first conveyor chain 6 indicated by a dash-dotted line.
  • the first conveyor chain 6 is driven by a chain wheel 12 lying between the guide device 8 and the magazine 10.
  • the first conveyor chain 6, the guide device 8 and the chain wheel 12 are each provided twice in order to be able to guide the lamellar sections 4 on their two narrow sides 14.
  • the configuration of the narrow sides 14 of the sections 4 described below also applies to the other narrow sides of the sections 4, which are not visible in the figures.
  • the sections 4 have on their narrow sides 14 bolts 16 which serve as attachment points for the movable suspension of the sections 4 on the first conveyor chain 6.
  • the sections 4 on their vertical narrow sides 14 each have lower guide rollers 20 adjacent to their lower edges 18 and upper guide rollers 24 adjacent to their upper edges 22.
  • the sections 4 also have on their narrow sides 14 arranged lateral extensions 31 serving as deflection means.
  • the extensions 31 are arranged so that the first conveyor chain 6 can be supported on it.
  • the lateral extensions 31 continue to point a curved surface 33 on which the first conveyor chain 6 rests.
  • the curved surface 33 is located on the side of the lateral extensions 31 facing away from the open position II.
  • the part of the lateral extensions 31 facing the open position II is formed with a straight surface 35.
  • the guide device 8 consists of a guide rail section 26, which defines the closed position I of the sections 4, and of an insertion section 32, which is connected in one piece to the guide rail section 26 and lies in the direction of the chain wheel 12.
  • the sections 4 can be moved within the guide device 8 and out of and into the guide device by means of the first conveyor chain 6 driven by the chain wheel 12.
  • the sections 4 run with their guide rollers 20, 24 within the guide rail section 26 of the guide device 8, which is designed as a hollow profile 25.
  • the diameter of the guide rollers 20, 24 is dimensioned to fit the clear inner width 30 of the hollow profile 25.
  • the first conveyor chain 6 has a course having a plurality of bulges within the guide rail section 26, in that it is pressed out of its course predetermined by the tensile force by the lateral extensions 31 of the sections 4.
  • the resulting counterforce of the first conveyor chain 6 on the lateral extensions 31 resulting from the tensile force cannot push the sections 4 to the side, since the sections 4 cannot move transversely to the course thereof within the guide rail section 26.
  • the insertion section 32 of the guide device 8 consists of a first shorter part 36 and a second longer part 38.
  • the first part 36 faces the open position II of the sections 4 and is designed as a first bevel, which is at an angle to Guide rail section 26 is.
  • the second part 38 of the insertion section 32 consists of a section 42 which continues the part of the guide rail section 26 facing away from the open position II and a second bevel 44.
  • the second bevel 44 is also at an angle to the guide rail section 26.
  • the first part 36 and the second bevel 44 is in each case plate-shaped in such a way that they each continue the two parts of the hollow profile 25 of the guide rail section 26 which are perpendicular to the plane of the drawing.
  • the second bevel 44 is angled toward the open position II of the sections 4 away from the side. Furthermore, the second bevel 44 is arranged at a distance z (see FIG. 2) from the end 45 of the guide rail section 26 on the opening position side; i.e. the section 42 continuing the guide rail section 26 has the length z. In addition, the distance z corresponds approximately to the same distance y at each section 4 between the two guide rollers 20, 24 (see FIG. 2).
  • the sections 4 are deflected by the chain wheel 12 in the direction of the magazine 10.
  • the sprocket 12 is arranged such that the guide rail section 26 is tangential to the sprocket 12 with its central axis.
  • the deflection of the first conveyor chain 6 or the sections 4 attached to it begins at the closing position-side deflection point 54, runs downward again via the zenith point 56 in the direction of the magazine 10.
  • the magazine 10 runs horizontally and the guide rail section 26 vertically.
  • the sections 4 are arranged side by side in the open position II.
  • the first conveyor chain 6 in the magazine 10 hangs down limply between the individual sections 4.
  • the first conveyor chain 6 hangs down in such a way that it lies against both the straight surface 35 and the curved surface 33 of the lateral extensions 31 of the sections 4.
  • the magazine 10 has a second conveyor chain 48 indicated by a broken line.
  • This second conveyor chain 48 is moved by second sprockets 50.
  • the second conveyor chain 48 runs at right angles to the guide rail section 26. the direction of movement of the sections 4 within the magazine 46 is perpendicular to the direction of movement of the sections within the guide device 34.
  • U-shaped pickups 52 which are open at the top are attached to the second conveyor chain 48. These transducers 52 receive the bolts 16 of the sections 4 with a precise fit, so that the sections 4 in the magazine 10 hang with the aid of their bolts 16 in the transducers 52.
  • the sections 4 are moved from the closed position I into the open position II as follows:
  • the sections 4, which are in the closed position I in the guide rail section 26 and suspended on the first conveyor chain 6 with the aid of the bolts 16, are pulled vertically upward in the direction of the sprocket 12 by the first conveyor chain 6. This initially creates a minimal distance between the sections 4. After the second guide element 24 located on the upper edge 22 has left the guide rail section 26, this is only guided by the section 42 of the insertion section 32 which continues the guide rail section 26 on one side.
  • first guide roller 20 As soon as the first guide roller 20 has left the guide rail section 26, it is supported on the first part 36 of the insertion section 32.
  • the section 4 is supported on the first conveyor chain 6 with the aid of the extension 31 and is thus pivoted in the direction of the open position II by the transverse component of the tensile force of the first conveyor chain 6.
  • the second guide roller 24 is supported on the second part 38 of the insertion section 32 on the second bevel 44.
  • Both guide rollers 20, 24 are supported at the same time, since the distance y between the two guide rollers 20, 24 corresponds approximately to the distance z of the second bevel 44 from the end 45 of the guide rail section 26 on the open position (see FIG. 2).
  • the sections 4 are guided in synchronism with the pivoting movement of the first part 36 and the bevel 44 of the second part 38 of the insertion section 32.
  • the pivoting movement of the section 4 is limited by the balance between the weight of the section 4 and the force exerted on the first conveyor chain 6 via the extension 31 on the one hand and the counterforce exerted by the transverse component of the tensile force of the first conveyor chain 6 on the other hand.
  • the section 4 can be pivoted freely in the direction the open position II is guaranteed before the section 4 with the bolts 16 reaches the deflection point 54 on the chain wheel 12 (see FIG. 2).
  • the pivoting movement of the sections 4 also causes the lower edge 18 of the section 4 emerging from the guide rail section 26 to be separated from one another over its entire length relative to the upper edge 22 of the section 4 still located in the guide rail section 26.
  • the vertical distance between the sections 4 increases, since the conveyor chain in the pivoted section 4 located outside the guide rail section 26 is no longer pressed out of the vertical course predetermined by the tensile force, but rather hangs vertically downward. I.e.
  • the additional conveyor chain length that is required within the guide rail section 26 for the bulged course of the first conveyor chain 6 due to the extensions 31 is available outside the guide rail section 26 as an additional length in the vertical direction.
  • the section 4 As soon as the section 4 has reached the deflection point 54, it is transferred from the first conveyor chain 6 via the chain wheel 12 into the open position II in the magazine 10 (see FIG. 2).
  • the section 4 runs over the zenith point 56 (see FIG. 3) on the chain wheel 12 until it is finally received on its lateral bolt 16 by the sensors 52 arranged on the second conveyor chain 48.
  • the first conveyor chain 6 Shortly before reaching the zenith point 56, the first conveyor chain 6 completely detaches from the curved surface 33 of the lateral extension 31, as a result of which the section 4 is pivoted into the vertical.
  • the diameter of the sprocket 12 is selected so that the section 4 pivoted into the vertical and the subsequent section 4 cannot interfere with one another; in the exemplary embodiment shown, the diameter of the chain wheel 12 is therefore greater than the thickness of the sections 4.
  • the second conveyor chain 48 then moves the sections 4 within the magazine 10 horizontally into a final parking position.
  • the sections 4 are conveyed in the reverse order with the aid of the second conveyor chain 48 in the direction of the chain wheel 12. Finally, they are deflected by the sprocket 12 in a vertical direction of movement, in which they, when hanging obliquely on the first conveyor chain 6, are finally introduced into the guide rail section 26 by the interaction of the insertion section 32 with the guide rollers 20, 24. The force exerted by the insertion section 32 on the guide rollers 20 results in a forced guidance of the sections 4.
  • the sections 4 When moving within the guide rail section 26, the sections 4 keep a minimum distance from one another, which is reduced to zero when the sectional door 1 is finally closed due to the fact that the sections 4 stand on one another due to the weight of the sections 4.
