Description
2284645 COUPLING BETWEEN TWO OBJECTS The invention relates to a coupling
between two objects. A coupling is known wherein each of the two objects is provided with a hole, in which two holes a coupling element is fixed, for instance by glue or other suitable 5 means.
It is the object of the invention to provide a coupling between two objects which is wholly without play, which can easily be placed from an active into an inactive situation and vice versa and which is simple and thereby inexpensive to manufacture.
With a view hereto the invention provides a coupling between two objects, each provided with a hole, by means of a coupling element inserted into both holes and fixable or fixed therein, wherein is each hole has a form widening towards the outside, the coupling element has a form complementary to the widening part of the hole the coupling element is pulled inward relative to the object against the wall of the widening part of the hole by means of fixation means actuable from outside, and in the situation in which the coupling element is fixed in relation to both objects these objects are mutually connected for transmitting force only via the coupling element.
A specific embodiment is that in which the fixation means comprise a screw which extends transversely of the longitudinal direction of the hole and which when tightened exerts an increasing force on an inclining surface present on the coupling element such that the coupling element is thereby pulled inward in relation to the object.
From the point of view of production technique the simplest embodiment is that in which the coupling element has a rotation symmetrical form. The advantage of rotation 2 symmetrical forms is that these can be manufactured very simply by milling on a lathe.
The invention also relates to components evidently intended for a coupling of the type according to the 5 invention, in particular a coupling element.
The invention will now be elucidated with reference to the annexed drawing, in which:
figure 1 shows a cut away perspective view of a coupling according to the invention; figure 2 shows a cut away perspective view of the coupling element which forms part of the coupling according to figure 1; figure 3 is a partly broken away perspective view of a variant; and figure 4 is a partly cut away perspective view of another variant.
Figure 1 shows two tubes 1, 2. Plugs 3, 4 respectively are inserted into these tubes. These plugs fit tightly into tubes 1, 2 and are each provided with a continuous hole, both designated with 5. Into these continuous holes fits an elongate coupling element 6. This has in its central zone a widening 7 consisting of two truncated cone-shaped parts 8, 9. Pins 10, 11 extend on the narrow ends thereof. The shape of the holes 5 corresponds with the described shape of the coupling element 6, such that coupling element 6 is movable in longitudinal direction in the holes 5. The pins 10, 11 have a peripheral recess 12, 13. These recesses 12, 13 serve to fix the coupling element 6 by means of screws 14, 15. As shown in figure 1, the screw engages with its rounded end 16, 17 onto the portion located furthest to the outside of the roughly semi- toroidal recess 12, 13. When the relevant screw is tightened as according to arrow 18 an inward pulling of the coupling element 6 into the plug 3, 4 therefore takes place as according to arrow 19. This results in a play- free contact between the truncated cone-shaped parts 8, 9 and the correspondingly formed widening part of the wall of the hole 5, whereby absence of play is ensured.
As shown in figure 1, the screws 14, 15 are introduced via holes 20, 21 in the tubes 1, 2 into threaded holes 22, 23 - 3 in the plugs 3, 4. For the sake of clarity the heads 24, 25 are shown protruding outside tubes 1, 2. It may be practical to use a variant wherein the heads 24, 25 are countersunk so that no head protrudes on the outside of tubes 1, 2.
In the coupled situation shown in figure 1 there is an interspace 26 between tubes 1, 2. In this way the tubes are mutually coupled only via the coupling element 6, thus ensuring absence of play.
It will be apparent that the coupling element can be integrated with one of both tubes 1, 2. The coupling element can in that case be formed as one whole with the object concerned by turning, casting or any other suitable process.
The other object must then be formed with a complementarily formed hole for coupling to the coupling element.
Figure 2 shows the coupling element 6 on enlarged scale.
Figure 3 shows that the coupling according to the invention is not only suitable for coupling tubes. A ring 27 can, making use of the invention, be coupled to tubes extending axially, radially or in other directions. Tube 2 is connected to ring 27 making use of coupling element 6. After the elucidation relating to figure 1 this structure does not require further explanation. Tube 2 extends radially relative to the ring 27.
Two tubes 28, 29 are coupled to ring 27 such that they both extend in axial direction. Use is made for this purpose of a coupling element 30 which has between the truncated cone-shaped parts 8 and 9 a cylindrical portion 31 with an axial length corresponding with the axial length of ring 27.
The coupling is otherwise the same as that described above.
Shown in the drawing is that the coupling element 30 is secured relative to the ring 27 by means of a screw 32. This is not strictly necessary as both tubes 28, 29 determine in the fixed situation the position of the coupling element 30 in relation to the ring 27. The screw 32 can however be useful during placing and removal of the coupling.
It is also the case in the embodiment of figure 3 that all screws will preferably be embodied such that they are placed in countersunk manner.
4 Figure 4 shows a variant which differs from the embodiment of figure 1 insofar as the tubes 33, 34 have a rectangular, in particular square, cross section. Each of the tubes 33, 34 has internally a plug 36, 37 into which the coupling element tapering towards the outside fits tightly. In accordance with the structure shown in figure 1 the coupling element 35 has an inclining surface 38 which serves to co-act with the fixing screw 39 such that when screw 39 is tightened an inward pulling of the coupling element 35 into the plug 37 takes place. In the coupled situation the tubes 33, 34 have an interspace 26.
The essential difference between the coupling according to figure 4 and that according to figure 1 lies in the fact that the coupling of figure 1 is wholly rotation symmetrical, which can facilitate placing of the tubes because the angular position is indifferent, otherwise than is the case of the coupling of figure 4.
The described couplings will generally be embodied in metal. It will be apparent that requirements will be made of the coupling element in respect of mechanical strength and rigidity.
