Abstract

A supporting device for setting with a large freedom of choice in the space, of a first object, like a computer keyboard is described. It is characterized by the following: a cylindrical body (1, 2), comprising an upper cylindrical part (1) and a lower cylindrical part (2). An upper piston (22) is axially movable in the upper cylindrical part (1) and a lower piston (6) is axially movable in the lower cylindrical part (2). The upper cylindrical part (1) is connected to a hollow body (24, 25), parted into two hollow body parts (24 and 25), with a gap (32) between them. A ball body (27) is grasped by the hollow body (24, 25) and the upper piston (22), and a shaft (26) is fixed to the ball body (27), pointing out through the gap (32), carrying said first object (30). The lower cylindrical part (2) is connected to a house (12, 13), which comprises two body halves (33, 34) each being connected to its pin halve (9, 10), which extend downwards to a fastener (18) in said second object. A wedge element (8) is provided, which can be acted upon by the lower piston (6), and an expander means (20, 21) is provided, which when acted upon by an outer means part, like a handle (21), can either bring the upper piston (22) and the lower piston (6) apart, locking, so that the ball body (27) is locked by the upper piston (22) and the wedge element (8) forces the two body halves (33, 34) apart, locking, so that the pin halves (9, 10) are locked in the fastener (18), or releasably admits, that the upper piston (22) and the lower piston (6) approach each other.

Description

502 675 3, 1 Simply described, the locking is accessed in such a way that a source of power is applied to the second output shafts, one of which output shafts is attached to the desired gear set. The piston of this shaft, so designed that it * pulls on a ball, which is articulated at 230 degrees in the nose cone. is also .ldbar in 360 degrees, just as the nose cone is rotatable in 360 degrees with its suspension in the cylinder. Everything is locked with a pressure from the power source that takes its counterforce from the bale joints, which thus gets the same amount of back pressure for the locking of these movements. The second piston is adapted as a wedge, the sorn blasts apart the second output shaft, which is divided in two and goes down into a circular hole and thus enables a 360-degree rotation. Suitable holes, provided either in a specially designed 'wicker or table bracket', or standardized in befm 'g furniture,' sink, shelf or similar where the cylinder is to be applied. The output split shaft, has in its rar; _ \. a shaft angled 90 degrees on each half, on which the pre-inclined cylinder is suspended.

C) The power package with its clamping handle can be made vndban run: c lizderna in 36 degrees to lighten the most comfortable locking position. The combination gives these possibilities I-l u the almost unlimited possibilities of variation.

Both the power package and the nose cone have quick couplings for replacing lcafïçxake- resp. of gear. i I DETAIL DESCRIPTION U 2) 3) 4) Ü Q Ü 3 9) 10) 11) 12) 13) 14) 15) 16) 17) 18) 19) 20) 21) 22) 23) 24) 25) 26) 27) 28) 29) so) Front cylinder part Rear cylinder part Carry fi ring part 1 Front part 2 Overhead sleeve Rear piston Frlktionsplava Wedge Rear shaft half l Rear shaft half 2 Bevel ring Control arm 1 Link arm 2 Shaft pin 1 Shaft pin 2 O-spindle handle Frilqíonsrín Noskonshalva l Noskonshalva 2 Front axle Ball bracket Locking ring for noskon Steering tool Gear 502 673 502 673 Image description description Figure 1, sheet 1, shows the structure of the Mechanical Cylinder in its entirety. It consists of the cylinder parts 1) and 2). Between the two cylinder parts is placed a power package, which is divided into two halves. Two identical driver parts of the power package simultaneously constitute an extension of the cylinder. The overshoot sleeve 5), which holds the two halves together, can itself consist of two stfnalvs.

The power package can be rotated 360 degrees in nt the cylinder body, to achieve the best working position, and is allowed by the ctions ilction plate between the balce piston 6) and S).

The posterior axis consists of two identical halves 9) and 10), the beveled sides ll) \ s »7 s ~ 'C, ~ a: uronar-.gca pa form a V-groove at about 250 degrees. The links 1) and 13 of the shaft halves' respective pivot pins 14) and 15) and anchored with an engagement in the balcre cylinder part 2). The O-ring 16) holds the halves together in separate nits. The groove 17) provides space for safety spirit, which locks the electrical halves 9) and 10) in the hole, by means of corresponding grooves in the inner wall of the fastener 18). Thus, the entire device can also be mounted upside down.

The locking principle in the rear part is that the wedge 8) with a 'force fi of the force package means that the pin formed by the two shaft halves 9) and 10), and which fits in a hole with precision about 1/10 below the hole diameter, has a curved circumference, and thus is pressed apart and fixed against the wall of the circular hole. The pressures in the hole are large, and in aluminum a steel sleeve is required, which can be rough. An extra locking knob can also be justified here. Tzimskirtav 19), as shown in Figs. 3, 2, is needed if one has to lock tightly on the power package to direct larger r towards the remote output shaft 26). Too much force at the rear can increase the halves - if not the screw 19). The influence of the force can also be regulated by: varying the wedge or V-groove of the tip vortex with each other.

In this sketch, the notch package consists of operating handles, which by threading actuate the wedge 20) and bring about expansion of the pistons 6) and 22). other sources of aiideraride power sources are possible.

The nose cones halves 24) and 25) are provided with a slotted groove in the division of the halves, 502 673 5 where the inner shaft 26) extends from its ball-fixed 27). Locking ring 28) for nose cone also quick coupling for replacing the implement 30) as well: the low shear holder. The locking ring holds the two nose cone halves in place around the cylinder. and spins with the nose cone with a tenth of a rnrn play over it. One half of the nose cone has a resilient ball in it, and a groove for guide pin 29), so that the locking ring can only move backwards and forwards in relation to the nose cones, so that all three of the nose cones can rotate 360 degrees around the cylinder. The nose cone then carries with it the outgoing shaft 26), which can then also be pivoted 230 degrees in the slot between the choir halves, at the same time as the shaft next to the shaft can be rotated 360 degrees. When the spanner is slack, it is possible to move the lock exactly backwards so much that only one half of the nose loosens, which then releases the ball with the shaft and the holder for tools. To change gear skis take: only a few dozen sectins. When the shell of the new tool is fixed, half of the nose cone is retracted and the locking ring is moved again until the small tenths ball fi xerast in the recess of the nose cone on the inside.

Figure 2, sheet 1 shows that the wedge 8) can have different tip turns depending on the desired power take-off.

Sheet 2, Fig. 4 shows the total radius of rotation 240 degrees, which is allowed by the rear axle, Fig. 5 and Fig. 6, shows a sharper shape when the wedge 8) bursts between the two rear shaft halves 9) and 10).

Sheet 3, Fig. 7 shows the appearance of the locking ring 28) in a dimensional manner, and Fig. 8 shows the appearance of the reading 28) schernatically and here it is seen in relation to the center line. The recess corresponds to the slot in the two nose cone halves 24) and 25).

Sheet 4, Fig. 9 shows the appearance when two angled cylinders are combined: down each other, to achieve both greater range and an increased range of motion.

The angle can be in the range 0 - 90 degrees, and requires that the rear lane arms 12) and 13) are suspended equal to the nose cone, so that they can rotate 360 degrees .fring cylinder. The control handle is in this case placed in the stall
