Abstract

A locking intended in a locked position to prevent rotation of a rotatory object (1) in one direction and to permit rotation in the opposite direction, is provided with a locking part (7) of the rotatory object, in the form of a straight, preferably hexagonal prism, coaxial with the rotatory object and a locking seat (8) for the locking part, which locking seat has a cavity (10) with a bottom and two opposite walls (11, 12) with different heights, the higher wall (11) of which is so high that during the rotation of the locking part in the allowed direction of rotation it is all the time in contact with one corner of the locking part, and with such a distance between the walls that the rotation of the locking part in the opposite direction is prevented due to the bearing of the opposite corners against the walls.

Description

ROTATION LOCKING
TECHNICAL FIELD
The present invention relates to a locking at a rotatory object, for example at a coil for winding a band, rope, wire or the like according to the preamble in the following independent claims.
BACKGROUND ART
For locking against turning one way but not in the opposite way at a coil for winding a band or the like there is known a spring-loaded pawl which interlocks into a ratchet wheel, connected to the coil. Depending on the design in detail a locking arrangement of this kind can be brough to perform a lot of operations, for example an optional b locking one way or the other, even total blocking against turning when required. In this arrangement several parts must co-operate in a complicated way; if a locking of this kind to be resistant to stress it often becomes heavy and clumsy.
DISCLOSURE OF THE INVENTION
The invented locking is characterized as is shown in the characterizing part of the following independent claims.
The locking seat co-operating with the locking part of the coil is completely stationary, thereby uncomplicated, but still gives a reliable locking to the coil against tension force in the band wound on it etc.
BRIEF DESCRIPTION OF DRAWING
In the following an example is described of the invented locking with reference to the attached drawing, where Fig 1 shows the coil and the locking in a side view,
Fig 2 shows the coil in an end view together with the locking and Fig 3 shows the coil in three different rotated positions in relation to the locking. Fig 4 shows a cab le holder, at which the coil and the locking are used and
Fig 5 shows a holder plate included in the cable holder.
MODE FOR CARRYING OUT THE INVENTION
The invented locking against rotation is exemplified by a locking for a rotatory object, in this case a coil, on which a band under tensile stress is wound.
The coil 1 is produced from a material bar in the form of a straight, multi-side prism, here a regular, hexagonal prism with plane sides. Part of the bar, as shown in Fig 1, is turned into a cylindrical part 2, on which the band is to be wound. In the cylindrical part 1 a through slot is made in longitudinal line for fastening the band.
At one end of the coil a bearing surface 4 is turned with the same diameter as in the cylindrical part 2. On each side of the bearing surface 4 the material of the bar is left in order to form two guiding flanges 5.
The coil 1 together with the bearing surface 4 is inserted in a bearing block 6 with a semicircle formed cavity as bearing for the coil. The bearing is not further described.
The opposite end of the coil retains the hexagonal cross section of the material bar, thus forming a locking part 7. The locking part is inserted in a locking seat 8 with a cavity formed so that the coil is locked for rotation in one direction.
The locking seat 8, as shown in Fig 2, is formed with a cavity 10 having a bottom with free space for the locking part 7. The cavity 10 is surrounded by two walls. One wall 12 is low, approximately half the size of the breadth of the sides of the locking part 7. The low wall 12 is ended with a rounded part 13 extending away from the cavity 10 and on the whole including a semi circle. The second wall 11 is higher, at least as high as to be in contact with one of the corners of the locking part during the rotation of the locking part 7 for winding up the band, in this example, so high that a line 20 from its outermost part to the nearest point of the rounding 13 forms an angle B of 75 against the higher wall 11.
The low wall 12 has an inclination of about 5 in relation to the high wall 11, the inclination is directed inwardly to the cavity 10.
Alternatively both the two walls 11, 12 can be parallel.
The distance between the walls 11, 12 is adjusted in relation to the largest diameter of the locking part 7 so that the rotation of the locking part for unrolling the band is blocked due to the bearing of the opposite corners against the walls, in the example the distance between the walls is 9 per cent less than the largest diameter of the locking part.
The bottom of the. cavity is formed as an elevated shoulder 14 close to the low wall 12. The shoulder is intended to support the locking part 7 among others in its locked position.
Both the locking seat 8 and the previously described bearing block 6 are made of steel plate.
The band 15 is partly wound on the cylindrical part 2 of the coil 1 and is under tensile stress. The coil with the band is by co-operation between the locking part 7 and the locking seat 8 locked in the position shown in Fig 2, with one corner of the hexagonal locking part being pressed against the upper part of the high wall 11, a diametrically opposite corner being pressed against the lower part of the low wall 12 and one of the plane sides of the locking part being supported by the shoulder 14 in the bottom of the cavity.
The locking of the locking part 7 has effect even when the angle A of the band 15 against the high wall 11 is permitted to vary, at least when the angle varies, within the limits 100 to 260 .
If the band 15 is releasably arranged it can be further wound on the coil 1 by rotation with a rotation tool, for example a spanner, on the protruding hexagonal part of the locking part 7. The different positions of the locking part during the rotation are shown in Fig 3, where the blocked position is shown by continuous lines, the position after a small rotation is shown by dashed lines and the position after further rotation is shown by dotted lines. Further rotation makes the locking part 7 once again drop into the cavity in a locked position as it is shown by the continuous lines.
During the rotation of the locking, part 7 from one blocked position to the following, one of the plane sides of the locking part will roll on the rounding 13 of the low wall 12, as shown in Fig 3, thus the locking part will be lifted from the cavity 10 of the locking seat 8. When the rotation continues, the corners of the locking part do no longer reach the rounding but slide down along the low wall so that the locking part finally again gets into a blocked position as before but with the locking part 7 turned 1/6 revolution.
The rotation of the locking part 7 is further illustrated by a radius 18 which, in the three different positions of the locking part is drawn to the same angle.
During the rotation the centre 19 of the locking part is moved out of the cavity 10 and finally back into the cavity when the locking part is in the locking position.
During the described movement of the locking part 7 the bearing surface 4 remains in the bearing block 6; the coil 1 thus making a rocking movement. To make this possible the bearing surface 14 is wider than the bearing block 6.
Due to the design of the invented rotation lock it is not possible to unwind the band 15 from the coil 1 by turning the coil. One possibility to let the band loose is that the locking part 7 is knocked from the cavity of the locking seat 18 with a hammer blow.
When the band 15 is used for binding and holding, the binding can be loosened by the loosening of the end of the band opposite the coil. Should this be. impossible, attempts can be made to turn the coil 1 in the direction of the winding until the band breaks, the binding thus being loosened.
The rotation locking according to the invention can, for example be used at a holder for a elongated body, a cable, a tube or the like. In the figures 4 and 5 a cable holder 21 is shown for a cable 22 indicated in the figure by a circular cross section. In the cable holder 21 is included a holder plate 23 of steel plate bent ia an obtuse angle in order to form a seat for the cable, thus enabling cables with different diameters to be fixed by the aid of the cable holder. The holder plate 23 is formed with an S-shaped fastening handle 24 the outer end of which is planar, in which handle a hole 25 is made intended for a fastening device hich shall fasten the cable holder on a surface.
A band 15 intended to be wrapped around the cable 22 to hold it, is fastened in the holder plate 23 by being inserted through two slots 27 of the holder plate, see also Fig 5, and then folded. The other end of the band 26 is fastened at a coil 1 and wound round.it. The coil 1, the block 6, the locking seat 8 and the band 15.the same as are described above.
