Caster with a bracket for its detachable attachment,

The invention relates to a roller with a device for releasable attachment to furniture, devices and apparatus and the like. It does not matter whether the feet of these objects are made of metal or wood and are tubular or solid are equipped with a mounting hole.

For the caster bracket are according to the different Types of fastening known more or less complicated constructions. Are the feet of the to be equipped with castors Solid object made of inelastic material such as metal, so you can insert it into the mounting hole of the device base cut an internal thread and use a roller, the vertical bearing journals in a known manner designed as a threaded bolt and is simply screwed into the mounting hole. On the other hand, are the feet of the Solid object to be provided with rollers made of soft material such as wood, so you usually care for the fastening hole of the device foot first drive a bearing sleeve and only then in this the back bolt of the To store roller fork. In the case of hardwood or tube feet are Roller mounts known that have a rubber inner sleeve or have an expansion sleeve that, after being inserted into the fastening hole or into the pipe end of the device base by means of an axially moving expansion cone in diameter enlarged and thus clamped.

The innovation relates to a roller with a holder for the detachable attachment of the roller in one Device or furniture foot o <, the like. That has a socket to be inserted into the mounting hole, which by tightening an axial screw bolt can be clamped.

In the case of the known roller mounts of this type, from Disadvantage that the Kiemmuffeneinrichtung from several different there are relatively complex individual parts that not only cause high manufacturing costs, but also require the selection of special materials with a certain elasticity, otherwise either the bracket The clamping does not occur due to insufficient expandability, or the fastening does not occur if the material is too soft is strong enough. As a result, and also from other z, B "constructive Reasons can be with the well-known caster stop only small tolerances of the mounting hole of the device foot or the like »bridge what, among other things has the disadvantage that a large number of clamping sockets or expansion sockets of different diameters are in stock must be kept.

To avoid these disadvantages, a roller bracket has already been used proposed in which the Kiemmufle consists of round socket wedges, the mutually facing end faces are beveled in a wedge shape that the round Sleeve wedges can slide on each other when tightening the axial screw bolt and radially against the Inner wall of the mounting hole are pressed, as is known from utility model specification 1 833 363.

Such a roller bracket consists of just a few simple designed parts and is very robust and capable of larger tolerances in the mounting hole of the device base or the like,

to bridge. However, it has the disadvantage that it is only suitable for device or furniture feet with a round mounting hole lets use. So far it was not possible to use rollers with such round wedge socket fastenings on pipes with square or rectangular cross-section. Because at Insertion of the roller holder equipped with round socket wedges into a square or rectangular tube foot there is only a linear contact between the wedge sleeves and the inner wall of the pipe, which means that the pipes when Tighten the screw bolt of the roller bracket in the mounting

are deformed by the supply range, to a certain extent / the necessary tightening torque, which must be in the range of 5 and 7 mkp _e

The innovation eliminates this disadvantage and provides a wedge socket fastening, with "" the castors as you like on round as well as on angular, in particular square, tubular feet of furniture, devices and apparatus or the like, attached can be.

The new roller, which has a holder for fastening the roller in a device or furniture foot ο "the like, which in a known manner one to be introduced into the mounting hole Has Kiemmuffe, which consists of round socket wedges, the mutually facing end faces so wedge-shaped are beveled so that the socket wedges can slide on each other when tightening the axial screw bolt and through Wedge effect are pressed radially against the inner wall of the mounting hole, is characterized according to the invention, that the round socket wedges on the circumference have several tangential flats that a use of the Clamping socket holder for both round mounting holes as well as for angular mounting holes and the when inserting the joint holder in a square device or Furniture foot tube when tightening the axial screw bolt come to rest against the straight inner tube surfaces, while

When inserting the clamping socket holder into a round appliance or furniture leg tube, the round circumferential sections of the socket wedges when tightening the axial screw bolt come to rest against the round inner wall of the pipe "

In other words, the new caster is a bracket for attaching the caster in a device or furniture base or the like. possesses, in a known manner one in the mounting hole has to be introduced clamping socket, which consists of socket wedges, the mutually facing end faces are bevelled wedge-shaped in such a way that the socket wedges slide on one another when the axial screw bolt is tightened can and be pressed radially against the inner wall of the mounting hole by wedge action, according to the invention characterized in that the outer jacket of the socket wedges consists of round jacket sectors and tangential ones in succession There is flattening that allows the clamping sleeve bracket to be used both for round mounting holes and for allow angular mounting holes in such a way that when inserting the clamping sleeve holder in a round device or Furniture foot tube when tightening the axial screw bolt the round jacket sectors of the socket wedges against the round inner pipe wall come to rest, while when inserting the clamping sleeve holder in a square device or furniture leg tube When tightening the axial screw bolt, the flattened jacket sections of the socket wedges against the straight inner pipe surfaces come to the plant «,

The invention is particularly advantageous in the case of rollers, which by means of a clamping sleeve holder both in round tubes as are also to be fastened in square or otherwise rectangular square tubes "

For this particular application, the new roller according to the invention is then characterized in that the round socket wedges of the joint socket attachment on the circumference four have tangential flats that use the Clamping socket holder for both round mounting holes as well as for square or otherwise rectangular mounting holes and when inserting the clamping sleeve holder into a square or otherwise rectangular square tube when tightening the axial screw bolt against the straight inner pipe surfaces come to rest, while with Insertion of the clamping socket holder in a round tube the round circumferential sections of the socket wedges when tightening the axial The screw bolt come to rest against the round inner wall of the pipe «,

In other words, the new roller is then according to the

that

Finding characterized / the outer jacket of the socket wedges of the gusset fastening successively from four round jacket sectors and four tangential flattened areas, one use of the clamping socket holder for round tubes as well as for square or otherwise rectangular tubes Allow square tubes in such a way that when inserting the clamping sleeve holder in a round tube when tightening the axial Bolts the round jacket sectors of the socket wedges against the round inner wall of the pipe come to rest while inserting the clamping socket holder in a square or otherwise rectangular square tube when tightening the axial screw bolt, the flattened jacket sections of the socket wedges come to rest against the straight inner pipe surfaces.

Such a wedge socket fastening according to the invention with a square flat can then be used for both round and square or otherwise rectangular mounting holes are used «Both round tubes and

mm Ci -

also with square or otherwise rectangular square tubes a surface contact between the wedge sockets and the round or straight pipe inner wall instead of «as a result It is no longer possible to deform the pipe feet in the fastening area of the 5th clamping sleeve bracket.

The invention has the particular advantage that at least with respect to round tubes and square square tubes, often but also with regard to round tubes and other square tubes, in each of the sizes with only one 10. single common wedge socket bracket can get by, whereby the storage can be reduced to at least half of the previous stock levels, which is the case with the diverse Types and sizes of casters is of great importance.

FIG. 7 is the plan view of FIG. 6 and shows the socket joint in Top view, showing their usability for a round tube as well as for a square tube with dash-dotted lines is.

According to FIGS. 1 to 5, this is an exemplary embodiment around a steering transport roller, in which the roller housing is formed from the back bearing 6 and the roller fork 7 Wheel 9 stored. A vertical screw or a screw bolt 1 as a bearing pin leads through the back bearing 6 or back bolts. The clamping sleeve parts sit on screw 1 the caster holder, by means of which the caster is attached in the bore 10 of the tubular furniture foot 11 here "

The clamping device of the roller holder has a clamping sleeve 2 injection-molded from plastic or metal, for example, which in this embodiment consists of two socket wedges 2a and 2b, the mutually facing end faces 3a and 3b are bevelled in a wedge shape. The one formed by the wedge surfaces 3a and 3b with the sleeve longitudinal axis 5 of the roller bracket In this embodiment, the angle is approximately 45 °. The socket wedges 2a and 2b are in this embodiment of identical shape and size, namely here the same plastic or »metal injection molded parts.

When the bolt 1 is attracted to the tensing of the roller bracket, the two cotter pins 2a and 2b are moved towards each other in the axial direction and slide along their 30 wedge faces 3a and 3b on one another from _e As a result, in FIG «l lower sleeve spline 2a is pressed to the left until that he against the .innenwändung of the mounting hole 10 to the plant

comes, while the l Upper in FIG _e sleeve wedge is moved rightward 2b in corresponding manner, until he comes "against the diametrically located inner wall of the mounting hole zur.Anlage, On further rotating tightening of the screw 1, the wedge sleeves 2a and 2b are the wedge effect of their inclined surfaces 3a and 3b pressed radially against opposite surfaces of the inner wall of the fastening bore 10 and thus give the steering transport roller an extremely firm hold in the fastening bore 10 of the device base 11 »Since the bore 15 of the socket wedges 2 is larger than the diameter of the screw 1, the socket wedges 2a and 2b can, if necessary, slide a considerable distance on each other when tightening the screw 1, so that larger tolerances of the fastening bore 10 can be bridged,

In the embodiment shown in FIG. 6 there is the Clamping sleeve made of three socket wedges 2a, 2b and 2c, all of which can be injection-molded from plastic or metal and of which the socket wedges 2a and 2b are of identical shape, while the socket wedge 2c is of a different shape. As with 17

is indicated by dash-dotted lines, the middle socket wedge 2c could also consist of two pieces, so that then the whole IClemmuffe 2 would consist of four identical wedge sockets, which are each lined up offset by 180 ° on the screw bolt 1, This results in a long-lasting one for special purposes Roller holder with an extremely large clamping force and stability.

According to FIGS. 3 to 5 and 7, the round socket wedges have

18th
