Definitions

  • the invention relates to a strut for a shelf or shelf element, with a pull rope that extends obliquely between two parallel shelf supports and one end of which is fixed to one and the other end to the other shelf support.
  • Such struts are known, usually in the form of a diagonal strut consisting of two crossing traction cables between two adjacent shelf supports.
  • Such a bracing leads to a mutual stabilization of the shelf supports involved.
  • the pull cables For the vertical alignment of the shelf supports, the pull cables must be adjusted to the correct length.
  • rope tensioners are often integrated into the pulling ropes. These work reliably, but their operation is made more difficult by the fact that the rope tensioners have to be rotated around their own axis for adjustment, which almost always leads to a torsion-like twisting of the pull rope itself. This leads to deformation losses, which is why the exact adjustment of the rope length requires experience.
  • the cable tensioners integrated into the pull cables can be a hindrance when loading the shelf.
  • the conventional rope tensioners are often designed with sharp edges, which can lead to damage to the goods if they hit the rope tensioner when they are stored on the shelf.
  • the invention is intended to create a strut for a shelf or a shelf element using a pull rope with which the effective rope length can be both shortened and lengthened easily and precisely without the risk of damaging the stored goods. Every adjustment movement should lead to a change in the effective rope length as immediately and without loss as possible. In addition, both when shortening and when lengthening the pull rope, an adjustment made should remain secured by itself.
  • one end of the pull rope is attached to a winch mounted on a pivot axis, the winch being in a frictional connection with a blocking element, which is designed to be rotatable relative to the winch and rotatable relative to the shelf support.
  • the inhibiting element be mounted on a rotation axis which is different from the rotation axis of the winch.
  • the axis of rotation of the winch extends at right angles to the plane spanned by the two shelf supports.
  • the axis of rotation of the locking element is arranged transversely to the axis of rotation of the winch without intersecting the axis of rotation of the winch.
  • the function and effect of the inhibiting element is that its movement is coupled with the movement of the winch in terms of gear technology, but that friction effects between the gearbox partners, winch and inhibiting element, also play a role insofar as the winch moves because of the inevitable friction effects between the gearbox partners cannot turn back without external intervention. Rather, an automatic turning back is prevented by the engagement of the blocking element, which for this purpose is designed to be rotatable both with respect to the winch and with respect to the shelf support.
  • the function and the effect of inhibiting movement can be achieved by using a worm shaft as the inhibiting element.
  • Their helical thread forms the one gearbox partner, which is in tooth engagement with a toothing that is non-rotatably designed with respect to the winch.
  • the winch exercises as it is under the The pulling rope is subject to tensile load, although its toothing exerts a force on the worm shaft, but this force cannot turn the worm shaft due to the internal friction of the winch and worm shaft system.
  • Once the winch has reached its rotational position, it remains inhibited by the constant engagement of the worm shaft. Without any other action, there is no turning back of the winch and unwanted relaxation of the pull rope.
  • the winch and the non-rotatable toothing formed thereon together form a one-piece component which, for. B. can be a plastic body.
  • the worm shaft can also be designed as a plastic body.
  • Adjusting and changing the tension of the bracing is done by turning the locking element on its axis of rotation.
  • the locking element is provided with a polygon drive on its axis of rotation, to which a corresponding hand tool can be attached.
  • the drive polygon can, for. B. be a hexagon socket to which an Allen key can be used as a hand tool.
  • Allen keys are widespread and are therefore mostly at hand.
  • the drive polygon For easy accessibility of the drive polygon, if the winch and the locking element are arranged in a housing at one end of the shelf support, the drive polygon is located in a housing opening or outside in front of a housing opening in the housing.
  • This housing opening is preferably located on the same side of the housing on which the pull rope is led out of the housing. Because this side of the housing is relatively easily accessible in order to adjust the tension of the bracing there.
  • the mechanism comprising the winch and the inhibiting element in a housing arranged at one end of the shelf support, these mechanical elements are accommodated in a location where there is usually sufficient space.
  • This end of the shelf support is preferably its upper end.
  • the housing at the lower end of the respective shelf support.
  • the housing is part of the respective column base. Because usually shelf supports are not placed directly with their profile end on the floor, but a support leg is used below.
  • the housing described here with the mechanism can be integrated into this. However, the rope tension must then be changed near the ground, which is less advantageous.
  • the housing has two housing sections in the longitudinal direction of the shelf support, of which the first housing section is arranged along the length of the shelf support and the second housing section is arranged outside the length of the shelf support.
  • the shelf support is a hollow profile, i.e. a completely closed or a partially open hollow profile
  • the first housing section is arranged inside and the second housing section is arranged outside and as an extension of the profile cross-section of the hollow profile.
  • the first housing section which is somewhat smaller in cross section, is then inserted in the manner of a plug into the profile cross section of the hollow profile, which is open at the end, in the longitudinal direction of the profile.
  • An additional securing of this very simple attachment is not necessary, since the tensile forces on the rope already effect the securing. Thanks to the plug-like housing, the assembly and, above all, the retrofitting of the strut on an existing shelf support can be done very quickly and easily.
  • the locking element is preferably arranged inside the second housing section, that is to say in the housing section arranged outside and in extension of the profile cross section.
  • the winch can, at least in part, be arranged within the first housing section.
  • the housing is composed of two housing parts that can be plugged together.
  • the parting plane of the two housing parts preferably extends in the longitudinal direction of the shelf support.
  • housing parts can also be provided with other means of their own in order to secure their plugging together.
  • the design with the two housing parts also enables particularly simple and inexpensive assembly and storage of the rotatable parts.
  • the mounting of the winch is divided between a bearing shell formed on the first housing part and a bearing shell formed on the second housing part.
  • the storage of the inhibiting element can also be divided up a bearing shell formed on the first housing part and a bearing shell formed on the second housing part.
  • a recess is proposed in the jacket surface of the winch, with a thickening formed at the end of the pull rope sitting in the recess in a form-fitting manner and thus securing the pull rope to the winch with tensile strength.
  • the Fig. 1 shows a shelf element according to the prior art.
  • Two parallel shelf supports 1, 2 are each connected to one another via shelf levels 4.
  • This consists of a first pull rope 3, which extends from the lower part of the shelf support 1 to the upper part of the shelf support 2.
  • Another pull cord 3 extends from the lower part of the shelf support 2 to the upper part of the shelf support 1. At their intersection, the pull cords 3 can additionally be connected to one another, but do not have to be.
  • a cable tensioner 3A operating with a threaded connection is provided on a partial length of each pull cable 3. If this is rotated about its axis, it changes its length, which leads to a change in the rope tension in the pull rope 3.
  • Such integrated cable tensioners work reliably, but their operation is made more difficult by the fact that the cable tensioners 3A are rotated about their own axis for adjustment, which is almost always accompanied by a torsion-like twisting of the pull cable 3. This leads to an additional Change in length, which is why the exact adjustment of the rope length requires experience.
  • the cable tensioners 3A integrated in the pull cables can be a hindrance when goods are being loaded or unloaded on the shelf levels 4.
  • the rope tensioners 3A are often designed with sharp edges, which can lead to damage to the goods if they hit the rope tensioner during storage or retrieval.
  • a strut according to the invention is shown for a shelf or shelf element.
  • the twisting of an element described in more detail below is converted into a change in the rope tension directly and without loss of twist.
  • a housing 10 is inserted into the profile of the respective shelf support 1, 2, preferably at its upper end.
  • the housing 10 there is a mechanism for setting and changing the cable tension in the pulling cable 3 leading to the housing 10.
  • the Fig. 3 shows the upper part of a shelf support 1 with the housing 10 fastened there, from whose housing side facing the other shelf support 2 the tension cable 3 leads out.
  • a polygon drive 8 in the form of a hexagon socket here.
  • a commercially available hand tool e.g. B. apply a hexagon wrench to either increase the tension in the pull cable 3 via the mechanism arranged in the housing or to lower it when the drive polygon 8 is turned in the other direction.
  • a drum-shaped winch 11 is rotatably mounted on an axis of rotation A1.
  • the pull rope 3 is preferably provided with a thickening 3A at this end ( Fig. 5 ), which is located in the recess on the lateral surface 11A of the winch 11.
  • the winch 11 can be divided lengthways in the region of its drum for fastening the pull rope 3.
  • the end of the pull cable is inserted into a recess between these two halves, and the halves are joined together again, the thickening 3A being caught between the two halves.
  • the pull rope 3 leads from its attachment to the winch 11 through the housing and emerges from the housing 10 at a housing opening 13.
  • the other end of the pull rope 3 is fixed at the bottom of the other shelf support, in this case therefore at the bottom of the second shelf support 2.
  • the pull rope 3 By rotating the winch 11 about its axis of rotation A1, the pull rope 3 can be wound onto the winch 11, as a result of which the freely running part of the pull rope 3 is shortened and the pull rope 3 is more tightly tensioned.
  • a locking mechanism works unilaterally and a separate, further mechanism would be required to cancel the locking effect again, e.g. B. if the tension rope was too tight or if it is desirable to adjust the shelf supports to loosen the tension of the tension rope.
  • a friction-based inhibiting mechanism instead of a blocking locking mechanism, a friction-based inhibiting mechanism, among other things, is used.
  • the friction-based mechanism consists in the combination of the winch 11 with an inhibiting element 12 designed as a worm shaft.
  • the winch 11 is at least in a frictional connection with the worm shaft 12.
  • a toothing 15 is formed on the winch 11, preferably in one piece. The teeth of this toothing 15 mesh with the worm shaft 12 as the other gearbox partner, with friction that is important for the inhibition occurring between the tooth flanks.
  • the locking element 12 designed as a worm shaft, is also rotatably mounted in the housing 10 on an axis of rotation A2, the axis of rotation A2 being different from the axis of rotation A1 of the winch 11. While the axis of rotation A1 of the winch 11 is at right angles to that of the two shelf supports 1, 2 Spanned plane extends, the axis of rotation A2 of the worm shaft 12 extends in the plane spanned by the two shelf supports 1, 2.
  • the axis of rotation A2 of the worm shaft 12 is arranged transversely to the axis of rotation A1 of the winch 11 without intersecting the axis of rotation A1 of the winch 11.
  • the inhibiting element 12 is provided with the polygonal drive 8 on at least one of its two end sections 17. Like the housing opening 13 for the pull rope, this is arranged on the side of the housing 10 facing the other shelf support.
  • the inhibiting element 12 can be provided at each of its two end sections 17 with a drive polygon 8, which is then located in a separate housing opening of the housing 10.
  • the tensioning and releasing of the pull rope 3 can optionally also take place from the other direction.
  • the polygon drive 8 is either countersunk in its housing opening, or it can protrude from the housing.
  • the inhibiting element 12 is mounted on its end section 17 provided with the polygon drive 8 in the housing 10, and also on its other end section 17.
  • the end sections 17 are cylindrical for this purpose.
  • the winch 11 is rotated either in one direction, i.e. increasing the tension of the tension cable, or in the other direction, i.e., reducing the tension of the tension cable, indirectly by turning the worm shaft 12 using the hand tool attached to the polygon drive 8.
  • the indirect drive of the winch 11 is a decisive advantage for the inhibiting effect achieved. Because every rotation of the worm shaft 12 leads to a rotation of the winch 11 due to the gear engagement of the toothing 15 of the winch 11 in the helical toothing of the worm shaft 12. However, the position once made remains stable, ie. H.
  • the inhibiting effect of the inhibiting element is based on the fact that the winch 11 can be rotated by rotating the worm shaft 12, but not the other way around, which is based on the friction on the flanks involved.
  • the worm shaft 12 thus inhibits the movement of the winch 11, although the worm shaft, viewed in and of itself, is mounted in the housing 10 such that it can rotate freely.
  • the housing 10 is composed of two housing parts 10A, 10B that can be plugged together, the parting plane of the two housing parts 10A, 10B extending in the longitudinal direction of the shelf support, as vertical.
  • the design with two housing parts 10A, 10B creates the possibility that the rotary bearing of the winch 11 is distributed over a bearing shell formed on the first housing part 10A and a bearing shell formed on the second housing part 10B.
  • a first bearing pin 16 is formed on the winch 11 in the exemplary embodiment, which supports the winch 11 in the first housing part 10A, and a second bearing pin at the other end of the winch, which supports the winch in the other housing part 10B.
  • the design with two housing parts 10A, 10B creates the possibility that the rotary bearing of the worm shaft 12 is also distributed over bearing shells 18 formed on the first housing part 10A and bearing shells 19 formed on the second housing part 10B.
  • the two housing parts 10A, 10B can, for. B. be connected by means of screws. However, such a screw connection is not necessary if the housing parts 10A, 10B are held in their plugged-together state by the shelf support 1.
  • the housing 10 has two housing sections 22, 23 in the longitudinal direction of the shelf support 1.
  • the first housing section 22 is arranged on the length of the shelf support and the second housing section 23 is arranged outside the length of the shelf support.
  • the shelf support 1 itself is a hollow profile into which the first housing section 22 is inserted in the longitudinal direction, while the second housing section 23 is located outside and in extension of the profile cross section of the shelf support. Since the outline of the first housing section 22 is also adapted to the inner contour of the profile cross section of the shelf support, the first housing section 22 sits flush in the profile cross section, whereby the two housing parts 10A, 10B are held together and they cannot separate from one another.
  • the other housing section 23 is somewhat larger than the housing cross section 22 seated in the profile cross section, so that a step 24 is formed in the transition from housing section 22 to housing section 23. With the step 24, the housing 10 is supported on the front edges of the shelf support 1.
  • the housing 10 including its two housing parts 10A, 10B is preferably made of plastic.
  • the winch 11 including the one formed thereon Tooth 15 and also the worm shaft 12 made of a plastic.
  • Only the pull rope 3 is made of metal. However, all of these parts can also consist of metal.
