Definitions

  • the invention relates to a hatch cover for a floor stairway device, which can be pivoted on a hatch box of the floor stairway device.
  • the invention further relates to a floor staircase device.
  • U1 discloses a hatch cover for a floor stairway device which is pivotally displaceable on a hatch box of the floor stairway device, comprising a fitting which has a fitting gear and a drive rod which can be displaced by means of the fitting gear, and wherein a locking pin is fastened to the drive rod, which in at least one position is attached to a on the hatch box arranged locking part cooperates to fix the hatch cover with respect to the hatch box.
  • the floor staircase device serves, for example, to temporarily make a storage room in a building, in particular in a residential building.
  • the storage room is, for example, in an attic of the building, and the attic can be an attic or an attic.
  • the storage room is directly delimited by a roof of the building.
  • the storage space is preferably accessible through its floor, in particular from an underlying space, in particular a living space. In this respect, the storage room is above the living room, in particular immediately above the living room.
  • storage room designating the room that is to be accessible via the staircase device from the room referred to as "living room”.
  • the "storage room” can also be used as a living room or the “living room” as a storage room.
  • the storage room can also be generally referred to as the first room and the living room as the second room.
  • the floor staircase device is now arranged in the floor of the storage room or the ceiling of the living room. It has the hatch box, hatch cover and a flight of stairs.
  • the hatch box is preferably arranged and fastened in a recess or recess in the floor of the storage room.
  • the hatch cover is in turn pivotally mounted on the hatch box.
  • the hatch cover is used to at least temporarily separate the storage space from the living space below or to make it optionally accessible.
  • the hatch cover is arranged in a first position such that it has a hatch box recess in the hatch box in a first position closes, in particular completely closes, and at least partially, in particular completely, releases in a second position.
  • the storage space can be connected to the living space or connected with the hatch cover at least partially open via the hatch box recess.
  • the floor staircase is still assigned to the floor staircase. This is arranged in such a way that after opening the hatch cover it is in a position or can at least be brought into a position in which a user of the floor staircase device can get from the living room into the storage room via the floor staircase.
  • the floor staircase is attached to the hatch cover so that it can be pivoted together with the hatch box.
  • the stairs can be pulled out or folded out. This is particularly the case if the floor height of the living space is so large that the user cannot easily reach the staircase even when the hatch cover is open.
  • the floor staircase is available as a folding staircase, in particular with two or three folding segments, as a sliding staircase, in particular with at least two sliding segments, or as a preferably extendable scissor staircase. Other configurations of the floor staircase are of course also possible.
  • the hatch cover can, for example, be acted upon by spring force, the spring force being directed in such a way that it urges the hatch cover in the direction of its first position, which can also be referred to as the closed position, or into it.
  • the spring force therefore creates a closing force with which the hatch cover is pressed against the hatch case.
  • a certain tightness of the floor staircase device is achieved because the hatch cover is forced into the closed position by the spring force, so that it preferably closes tightly with the hatch box or rests against it, so that the hatch box recess is completely overlapped or closed by the hatch cover.
  • the tightness of the floor staircase device is usually the better, the more the spring force pushes the hatch cover into its closed position or against the hatch case.
  • the operability of the floor stair device is impaired by the stronger spring force because the user first of all the spring force must counteract to deflect the hatch cover from the closed position.
  • the support of the user by the spring force is limited to a closing process of the hatch cover, in which it is shifted from the second position, which can also be referred to as the open position, in the direction of the closed position or into the closed position.
  • the open position in the direction of the closed position or into the closed position.
  • the user has to counteract the spring force.
  • a fitting which has a fitting gear and a plurality of connecting rods which can be displaced by means of the fitting mechanism and which are arranged on different sides of the hatch cover, at least two of the connecting rods being operatively connected to one another via a corner deflection, and a locking pin being fastened to at least one of the connecting rods which cooperates in at least one position with a closing part arranged on the hatch box for fixing the hatch cover with respect to the hatch box.
  • the hatch cover has the fitting by means of which it can be fixed with respect to the hatch box.
  • the hatch cover is therefore not, or at least not only, held in its closed position by means of the spring force explained above with respect to the hatch case. Rather, the fitting is provided for this purpose.
  • the fitting has the fitting gear and several drive rods.
  • the drive rods can be driven or displaced by means of the fitting gear.
  • an actuating element of the hatch cover for example a handle or the like, is operatively connected to the drive rods via the fitting mechanism.
  • the drive rods are also displaced.
  • the gear mechanism is intended to convert a rotary movement of the actuating element into a linear displacement of the drive rods.
  • the fitting mechanism acts directly on at least one of the drive rods for this purpose.
  • An active connection of the fitting mechanism can be made via this drive rod another of the drive rods.
  • the hardware gearbox is not necessarily in direct operative connection with all drive rods.
  • At least two of the connecting rods are operatively connected to one another via the corner deflection, so that they can be arranged on different sides of the hatch cover.
  • the drive rods are usually present on one end face or several different end faces of the hatch cover.
  • the corner deflection enables a direct operative connection to be established between drive rods which are angled against one another, that is to say do not run parallel to one another.
  • the drive rods which are operatively connected to one another via the corner deflection are present at an angle to one another which is greater than 0 ° and less than 180 °. In particular, the drive rods are at an angle of approximately 90 °, in particular exactly 90 °, to one another.
  • the drive rods are directly connected to each other via the corner drive. This means that one of the drive rods engages directly on a first side of the corner deflection and another of the drive rods on a second side of the corner deflection opposite the first side.
  • the locking pin should now be attached to at least one of the drive rods.
  • several locking pins can be attached to the at least one of the drive rods.
  • such a locking pin in particular exactly such a locking pin, is attached to several of the drive rods, for example to all of the drive rods.
  • a locking pin is fastened to opposing drive rods, which in particular run at least approximately, in particular exactly, parallel to one another.
  • these locking pins are at least approximately opposite one another, for example in a specific position of the connecting rods which are operatively connected to one another.
  • the striker is assigned to the striker. If several locking pins are provided, such a locking part is of course assigned to each of the locking pins.
  • the locking pin interacts with the locking part in at least one position in order to fix the hatch cover with respect to the hatch box.
  • the closing part is arranged or fastened to the hatch box. If only one locking pin is discussed below, the explanations can of course be transferred analogously to further locking pins. The explanations therefore preferably apply to each of a plurality of locking pins which are provided on the hatch cover.
  • the position in which the locking pin interacts with the locking part for fixing the hatch cover can be referred to as the locking position, for example.
  • the locking pin can preferably be arranged either in the locking position or in a release position. While it interacts with the closing part in the locking position for fixing the hatch cover, it releases a shift of the hatch cover in the release position, in particular a shift of the hatch cover from the closed position.
  • the locking pin is in engagement in the locking position with the locking part, so it engages in it. In the release position, however, the locking pin is out of engagement with the locking part, and is particularly preferably at a distance from the latter.
  • the locking pin is preferably fastened to one of the drive rods, which is spaced apart from the fitting mechanism, that is to say it is only operatively connected to it indirectly via a further one of the drive rods.
  • the locking effect achieved by means of the locking pin can be used particularly flexibly.
  • the locking pin can be fastened to the drive rod that is directly connected to the fitting gear.
  • the described design of the hatch cover or the fitting has the advantage that the closing force with which the hatch cover is pushed in the direction of its closed position or on the hatch case can be selected independently of the spring force. This means that the spring force can be selected regardless of the sealing effect to be achieved.
  • the operation of the floor stairway device can be simplified because the spring force - if present - can be selected to match the hatch cover, so that the spring force compensates or almost compensates for the influence of gravity on the hatch cover in at least one position of the hatch cover.
  • the spring force is selected such that the hatch cover is held in its closed position by the spring force, but is not pushed against the hatch box when the hatch cover is released for displacement by means of the fitting, i.e. the at least one locking pin is in its release position. This means that the spring force in the closed position corresponds exactly to the influence of gravity on the hatch cover in this position or is at least slightly greater.
  • the described hatch cover achieves an excellent tightness of the floor stair device. This applies in particular if at least one locking pin is attached to several of the drive rods.
  • a first drive rod selected from the drive rods is operatively connected directly to the fitting gear and, via a corner deflection, to at least one second drive rod selected from the drive rods. Both the first drive rod and the second drive rod are each present as a subset of the drive rods described above.
  • the first drive rod is that of the drive rods which is directly connected to the fitting gear or is directly connected to it.
  • the second drive rod is operatively connected to the first drive rod via the corner deflection, so that it is only indirectly connected to the fitting gear mechanism, namely via the first drive rod.
  • a plurality of second connecting rods can be provided, which are preferably spaced parallel or at least almost parallel to one another on the hatch cover.
  • Each of these second drive rods is operatively connected to the first drive rod via a corner drive.
  • the second drive rod or the plurality of second drive rods can be driven by means of the fitting mechanism via the first drive rod.
  • the first drive rod is designed without a locking pin.
  • no locking pin is arranged or attached to the first drive rod.
  • a locking element is present on the fitting gear, for example a locking hook.
  • the locking element is, for example, in operative connection with the actuating element of the hatch cover, in particular directly or via the fitting gear.
  • it can be provided that it is rotatably mounted on the hatch cover, so that when the actuating element rotates, the locking element describes a corresponding rotational movement.
  • the locking element can be in the locking position and the release position analogous to the locking pin.
  • the locking position In the locking position, it interacts with a locking counter-element of the hatch box to secure the hatch cover with respect to the To fix hatch box.
  • the locking element In the release position, however, the locking element is out of engagement with the locking counter-element, so that the hatch cover is released for displacement with respect to the hatch box.
  • the locking element is preferably present in its locking position when this is also the case for the locking pin. The same applies to the release position. To this extent, the locking effect of the hatch cover can be further improved with the aid of the locking element.
  • the at least one second drive rod has the at least one locking pin, in particular a plurality of locking pins spaced apart from one another. While it can of course be provided that the second drive rod has exactly one locking pin, a plurality of locking pins spaced apart from one another are preferably provided.
  • the distance between the locking pins present on the drive rod corresponds, for example, to the length of a section of the drive rod divided by the number of locking pins on this drive rod reduced by one.
  • the length of the section is preferably at least 50%, at least 60%, at least 70%, at least 75%, at least 80%, at least 90% or at least 95% of the total length of the drive rod.
  • the total length of the drive rod corresponds in particular to the dimensions of the drive rod in the direction in which it has its largest dimensions.
  • the second drive rod overlaps the side of the hatch cover on which it is arranged to at least 50%, at least 60%, at least 70%, at least 75%, at least 80% or at least 90% ,
  • the second drive rod is arranged on one side or end face of the hatch cover. Its longitudinal central axis preferably points in the direction of the greatest extent of this end face of the hatch cover. The further the second drive rod overlaps the side of the hatch cover, the more flexibly the closing force achieved by means of the locking pin can be positioned.
  • the locking pin is preferably part of a center lock, so that it is arranged approximately centrally in the direction in which the front side of the hatch cover has its largest dimensions, for example between 40% and 60% based on the dimensions explained above, based on one of the Ends of the face.
  • the second drive rod completely or at least almost completely overlaps the side of the hatch cover, so that a third drive rod opposite the first drive rod can be arranged on the hatch cover, which has a corner deflection with the second drive rod or at least one of the second Connecting rods, is connected.

  • the drive rod 19 also has two locking pins 25 and 26 (not visible here), which are arranged analogously to the locking pins 23 and 24.
  • the fitting 15, in particular the connecting rods 17, 18 and 19, are arranged on the hatch cover 3 at a distance from the cover layers 11 and 12. In particular, they are arranged on the core 10 or rest against it. They are particularly preferably fastened to the core 10, in particular mounted such that they can be moved.
  • each drive rod 17, 18 and 19 is preferably assigned a cover rail 27, 28 and 29, respectively, which covers, in particular completely, covers the respective drive rod 17, 18 and 19, respectively.
  • the drive rods 17, 18 and 19 are arranged in drive rod receptacles 30, not shown here, of the hatch cover 3, in particular of the core 10, and overlapped by the cover rails 27, 28, 29.
  • the cover rails 27, 28 and 29 close off or overlap the respective drive rod receptacle 30.
  • the cover rails 27, 28 and 29 are purely optional and serve above all to improve the visual impression of the floor staircase device 1.
  • the Figure 4 shows a sectional view through a region of the hatch cover 3.
  • the core 10 is configured in several parts and consists of a carrier element 31 and an insulating body 32.
  • the carrier element 31 preferably completely surrounds the insulating body 32, in particular at least in a plane lying parallel to the cover layers 11 and 12.
  • the cover layers 11 and 12 preferably each abut the carrier element 31 and are fastened to it, preferably on opposite sides.
  • the insulating body 32 also lies against both the cover layer 11 and the cover layer 12. To this extent, the insulating body 32 is enclosed between the cover layers 11 and 12 and the carrier element 31 and held there.
  • the fastening element 13 mentioned above is fastened to the cover layer 11 in such a way that it is present in the region of the carrier element 31.
  • the carrier element 31 preferably consists of a material which has a higher rigidity than a material of the insulating body 32.
  • the fastening element 13 can accordingly can be reliably fastened to the hatch cover 3 in the region of the carrier element 31, for example by means of at least one screw engaging in the carrier element 31.
  • the drive rod receptacle 30 is formed in the core 10, in particular in the carrier element 31, preferably completely.
  • the drive rod receptacle 30 is arranged spaced from the cover layers 11 and 12.
  • a seal 33 is provided which is fastened to the hatch cover 3, in particular to the core 10, particularly preferably to the carrier element 31.
  • the seal 33 engages, for example, in a seal receptacle 34 a, which is formed in the carrier element 31, in particular at a distance from the cover layers 11 and 12.
  • the seal 33 surrounds the hatch cover 3 preferably completely in the circumferential direction and is present as a sealing ring. If the hatch cover 3 is in its closed position, the seal 33 should lie sealingly on the hatch case 2, in particular thus on the one hand rest against the hatch case 2 and on the other hand against the hatch cover 3.
  • the Figure 5 shows a closing part 35, which is arranged and fastened to the hatch case 2, in different views.
  • the locking part 35 is intended to cooperate with one of the locking pins 23, 24, 25 and 26 for fixing the hatch cover 3 with respect to the hatch case 2.
  • the locking part 35 has a locking pin receptacle 36 which has an inlet slope 37.
  • the locking part 35 is arranged on the hatch case 2 such that the respective locking pin 23, 24, 25 or 26 can enter the locking pin receptacle 36 through an entry opening 38. There he comes into contact with the inlet slope 37.
  • the inlet slope 37 preferably extends over the distance 12 which corresponds to at least 25%, at least 50% or at least 75% of the longitudinal extent l 1 of the locking pin receptacle 36.
  • a holding area 39 can adjoin the inlet slope 37, in particular directly. This holding area 39 runs straight, so that the closing force caused by the locking pin 23, 24, 25 or 26 on the hatch cover 3 in the direction of the hatch box 2 is independent of the position of the locking pin in the holding area 39.
  • the floor staircase device 1 described can be provided with a spring element which causes a spring force on the hatch cover 3, which is directed in the direction of its closed position.
  • a spring force can be exerted on the hatch cover 3, which counteracts the influence of gravity thereon.
  • the spring force in at least one position of the hatch cover 3, for example the closed position is as large as or slightly larger than the force on the hatch cover 3 caused by the influence of gravity, so that this is compensated for by the spring force in the at least one position.
