Definitions

  • the invention relates to a mounting device, in particular for connecting two plates.
  • the invention also relates to a counter holder for a mounting device and the use of a spring washer, a lock nut and a screwing tool for a mounting device.
  • plate connectors For the connection of individual pieces of furniture, in particular kitchen furniture and worktops, so-called plate connectors are known, which are inserted into the cutouts of the plates to be connected.
  • the plate connectors have two holding plates, which are each adapted to the milling of a plate.
  • the two holding plates can be clamped against each other using a screw bolt.
  • the counterpart to the screw bolt is usually formed by a hexagon nut.
  • a fork wrench is usually used to actuate the hexagon nut, but can only be pivoted by a small swivel angle after attacking the hexagon nut, so that the fork wrench has to be repositioned frequently. Therefore, the assembly is relatively complex, especially since automation is not possible or only with great effort.
  • hexagon screwdrivers for hexagon socket screws. Since the hexagon screwdrivers have a ball head that is suitable for engaging in the receptacle of the Allen screw, the Hexagon screwdrivers can also be set at a small angle with respect to the axis of the screw to be screwed. However, it is disadvantageous that this angle is too small to ensure adequate access to the components of the screw connection in the assembly problem described at the beginning.
  • a socket wrench can be used in the installation problem described at the beginning, which can be used at an angle with respect to the axis of the screw to be screwed , Even if a gripping of a tool is no longer required due to this solution, the angle between the longitudinal axis of the screw to be screwed and the longitudinal axis of the socket wrench is still relatively small, so that relatively large cutouts in the plates to be connected are required in order to achieve a sufficient Ensure access of the socket wrench to the screw head or to a screw nut.
  • an assembly device with a threaded nut which can be screwed onto a threaded rod and which has radial corrugation on the end face, and with a counter-holder which can be plugged onto the threaded rod the corrugation of the threaded nut side has at least one recess for receiving a drive pinion.
  • the mounting device has the essential advantage that the screw connection can be driven from a direction perpendicular to the threaded rod.
  • the drive pinion and the corrugation of the threaded nut form a crown gear, whereby the rotation of the drive pinion is deflected by 90 ° to the rotation of the threaded nut.
  • a counter-holder is provided which can be plugged onto the threaded rod and has at least one recess for receiving the drive pinion. The cutout prevents the drive pinion from being lifted from the corrugation of the threaded nut by the forces occurring when the threaded nut is driven, as a result of which no more driving forces could be transmitted.
  • a milled-out area surrounding the counter-holder can be made particularly small, since an attack of a tool no longer has to take place in a relatively small, i.e. acute angle to the longitudinal axis of the threaded rod, but directly from a vertical direction, that is to say in the opening direction cutout.
  • the power transmission between the drive pinion and the radial corrugation of the threaded nut takes place through toothed engagement of the drive pinion with the corrugation. It is not necessary that the toothing of the drive pinion fits geometrically perfectly to the corrugation of the threaded nut. It is sufficient if the corrugation of the threaded nut is designed in such a way that teeth of the drive pinion can be brought into engagement with teeth of the corrugation at least in sections. Since the for Connecting two plates used fittings are not often disassembled and reassembled, there are also no highest requirements with regard to the durability of the corrugation of the threaded nut.
  • the corrugation is designed to be so durable that at least some assembly and disassembly operations can be carried out.
  • One or more cutouts can be arranged in the counter holder. For example. there is only one recess in the counter holder, which makes it particularly simple. A plurality of, for example four, cutouts can also be provided, as a result of which the drive pinion can optionally be inserted into one of the cutouts. With such a configuration, it is not important during assembly to mount the counter-holder in a specific position, since the drive pinion can be accommodated in the cutout which is best suited for simple assembly, and which therefore faces the fitter, for example ,
  • the cut-out of the counter-holder is advantageously groove-shaped or groove-shaped.
  • the groove or the groove forms a shell-shaped bearing surface for the drive pinion, which is designed, for example, as a pin with teeth extending in the longitudinal direction of the pin.
  • Such a drive pinion can be at least partially received in the groove or groove formed in the counter holder, so that it can be supported well.
  • the groove or groove-shaped recess is part-circular in cross section.
  • the drive pinion can be supported equally well along part of its circumference. Extends the nut- or groove-shaped recess, for example over a circle segment of 180 °, the drive pinion can also be supported in an angular range of approximately 180 °. Due to the part-circular design of the cross-section of the groove-shaped or groove-shaped recess, the drive pinion, which is usually rotationally symmetrical, can be held well in its position relative to the threaded rod.
  • the recess extends essentially in the radial direction, so that the longitudinal axis of the drive pinion and the longitudinal axis of the threaded rod intersect.
  • the recess it is also possible for the recess to be arranged slightly offset from a radial direction.
  • the counter holder has an opening through which the counter holder can be plugged onto the thread holder. This means that the counter holder can be easily pre-assembled on the threaded rod.
  • the opening should be large enough to allow the counterholder to be moved on the threaded rod without tilting the thread of the threaded rod.
  • the end face of the threaded nut provided with the corrugation lies in one plane, the counter-holder being disc-shaped, at least in sections.
  • This embodiment enables the threaded nut to be driven from a direction perpendicular to the longitudinal axis of the threaded rod.
  • the corrugation can be provided in a bevel gear section of the threaded nut, the counter-holder being funnel-shaped at least in sections.
  • the corrugation of the threaded nut has elevations and depressions which extend in the radial direction and have an increasing spacing from one another from radially inside to radially outside.
  • a tooth profile formed in this way is relatively easy to produce, for example by cold forming.
  • the recesses in the corrugation form receiving areas for the tooth tips of the drive pinion.
  • the raised areas of the corrugation of the threaded nut can be accommodated in the tooth feet of the toothing of the drive pinion.
  • the corrugation of the threaded nut may have elevations and depressions which form the toothing of a crown gear.
  • the drive pinion With a corresponding design of the drive pinion, such toothing enables precise engagement of individual teeth along the entire engagement length. Even if such toothing is more complex to produce, it may be desirable, particularly in the case of furniture in the high-end area, to provide such a crown gear toothing.
  • the drive pinion is provided as a screwing tool or as an attachment for a screwing tool.
  • the drive pinion can have a corresponding handle with which the drive pinion can be rotated manually.
  • the screwing tool in the simplest case consisting of a simple handle, however, for example, can also be formed by a machine-operated tool.
  • a Torx® bit can preferably be provided, which can be inserted into the drill chuck of a drill or a cordless screwdriver. As a result, the drive pinion can be driven and thus the assembly device can be installed particularly quickly and conveniently.
  • a crown gear mechanism is formed by the engagement of the drive pinion, for example the Torx® bit, with the corrugation of the threaded nut.
  • the counter-holder for a mounting device can also be formed by a spring washer. Due to the corrugated shape of the spring washers, recessed areas are formed which can serve to receive a drive pinion.
  • ratchet teeth must be strong enough to enable a toothed engagement with a drive pinion.
