Abstract
Description
- This invention relates to a multi-way lever, a so-called "joy-stick" which, for example, is comprised in a manipulator.
- Multi-way levers of this kind can in normal cases be moved from a central non-operative position in any directions. Multi-way levers of the kind here referred to often are used at machines and the like where several valves are desired to be controlled by one and the same operating lever.
- Multi-way levers of this kind normally are supported at their lower end by two spring-loaded electric potentiometers, which are arranged perpendicularly to each other and capable each to emit an electric signal, so that the two signals together deliver information on the direction, in which the lever has been moved from the non-operative position, and on the distance of the lever movement from said position.
- At a usual construction, the springs at the potentiometers together tend to maintain the lever in vertical non-operative position. The joint members, in which the lever is suspended, generally are yokes, on which the potentiometers and springs are mounted.
- This construction, at which the springs are helical ones, does not permit the force, which is required for moving the lever from non-operative position, to be so varied as often is desired. Said force should be variable in such a manner, for example, that a much greater force is required when the lever has been moved through a certain distance from the non-operative position. At known constructions, furthermore, the force required for initiating the lever movement out of non-operative position is very small. As a result thereof, the person operating the lever must strain the arm in order to prevent the lever from being moved through too great a distance out of non-operative position when the deflection desired is only a small one.
- A further disadvantage of known multi-way levers is their structural height which, from the upper surface of an instrument inward to the panel, is great, due to the space required for said yokes and springs.
- An essential desire, which cannot be satisfied by the present state of art, is a multi-way lever so designed that for moving the lever in some selected directions the force required is smaller than in the remaining directions.
- The present invention eliminates entirely the aforesaid disadvantages and permits a multi-way lever to be designed so as to satisfy the said desire.
- The present invention, thus, relates to a device at a multi-way lever, a so-called "joy-stick" which, for example, is comprised in a manipulator, comprising a housing and projecting therefrom a control lever, which is hinged at its end located in the housing,and characterized, in that a sleeve is mounted concentrically about the lever, which sleeve at one end is provided with a conic surface intended by action of spring force on the sleeve to abut a plate with a slide surface, which includes a central portion with a conic surface and outside said portion a portion concave to the sleeve, which conic surface is formed so that the conic surface of the sleeve upon abutment to the conic surface of the slide surface is centered with respect to the slide surface.
- The invention is described in greater detail in the following, with reference to the accompanying drawings, in which
- Fig. 1 is a section through a multi-way lever, to which the invention is applied,
- Fig. 2 is a downward directed view along the line A-A in Fig. 1,
- Fig. 3 shows a modified embodiment of the invention, one detail shown in the same view as in Fig.2,
- Figs. 4, 5 show rolled-out circular sections of the detail in Fig. 3, and
- Figs. 6,7 show two modified embodiments.
- In Fig. 1 a multi-way lever 1 is shown, to which the invention is applied.
- The multi-way lever 1, for example, is comprised in a manipulator and comprises a
housing 2 and projecting therefrom acontrol lever 3. At the upper end of the lever 3 aball 4 or corresponding member is located, which is held gripped when the lever is operated. To the lower end of thelever 3 twopotentiometers lever 3 is located at the lower end thereof on the same level as the intersecting point between the twolines 7,8. Thelever 3 is attached to its fulcrum in a first joint member 9 so that thelever 3 can be moved in the plane of the drawing in Fig. 1. Said first joint member is hingedly attached to a second joint member 10,11, so that thelever 3 can be moved in a direction perpendicular to the plane of the drawing in Fig. 1. Said two joint members 9,10,11, thus, together render it possible to move thelever 3 in any direction out of its non-operative position shown in Fig. 1. - The
numeral 12 designates the upper surface of an instrument panel or corresponding means. The aforedescribed attachment of thelever 3 to the joint members 9,10,11 and the location and design of thepotentiometers - According to the invention, a
sleeve 13 is located concentrically about thelever 3. Thesleeve 13 is provided at one end with aconic surface 14, amd theentire sleeve 13 preferably is axial-symmetric. At least, however, theconic surface 14 preferably is axial-symmetric. - A
plate 15 further is provided, which has aslide surface 16, against which the sleeve is intended to slide. Saidslide surface 16 of theplate 15 includes aportion 17 with a conic surface so formed, that theconic surface 14 of thesleeve 13 upon abutment to the conic surface of theslide surface 16 is centered with respect to the slide surface, as shown in Fig. 1. - The
sleeve 13 is located about thelever 3 between the free end thereof and saidplate 15. Acompression spring 19 of helical type is located between thesleeve 13 and aseat 18 at the free end of the lever and, thus, presses thesleeve 13 down against theslide surface 16. When theconic surface 14 of thesleeve 13 abuts theconic portion 17 of theslide surface 16, thelever 3 is centered automatically by action of the spring force to the non-operative position shown in Fig. 1. - As appears-, from Fig. 1, the
sleeve 13 is moved to the free end of thelever 3 when the lever is moved in any direction from the non-operative position. - The
slide surface 16 is inclined radially and has its lowermost point at theconic portion 17. As a result thereof, the lever automatically returns to non-operative position by action of the spring force of the'spring 19, irrespective of in which direction and how far from the non-operative position the lever has been moved. - The portion of the device located above the
instrument panel 12 preferably is protected by arubber sleeve 20. - In Fig. 3 a modified embodiment of the invention is shown, at which the
plate 15 has been given a modified design. Saidplate 15 is designed in Fig. 3 by thenumeral 21. Like theplate 15, theplate 21 has aconic portion 17. - According to this embodiment, the plate has different heights in different radial directions. In Fig. 4 the
outer periphery 22 of theplate 21 is shown rolled-out, and in Fig. 5 a circular section at 23 is shown. Said circular section is an axial cross-section through the plate along theupper edge 32 of theconic portion 17. Theconic portion 17 is axial-symmetric with the same form as shown in Fig. 1. The height of theplate 21 radially outside the conic portion varies so, that the plate is highest along fourradii plate 21 is lower along radii 28-31, which are offset 45° in relation to the radii 24-27. - The position of the radii is indicated by said numerals in Figs. 3 and 4. Between its higher and, respectively, lower portions, the
plate 21 assumes sinus shape as shown in Fig. 4. - The amplitude of the sinus shape successively decreases for circular concentric sections through the
plate 21 and is completely abolished at saidinner periphery 23, see Fig. 5. According to this embodiment,of the invention, the greatest diameter of thesleeve 13 is smaller than at the embodiment shown in Figs. 1 and 2, in order that the lower portion of the sleeve shall abut not only the higher portions 24-27 of theplate 21. - Owing to this design of the
plate 21, relatively little force is required for moving thelever 3 radially out from its non-operative position in four mutually perpendicular radial directions. After having been moved radially along such a direction, thelever 3 can be moved perpendicularly to the radial direction, i.e. so that thesleeve 13 passes over a higher portion of theplate 21. For this, however, a substantially greater force is required. - An operator, thus, easily will sense four mutually perpendicular directions, which is of great importance for manipulators at certain machines.
- The
plate 21, of course, can be designed according to the principle described with reference to Figs. 3 and 4, but instead in such a manner, for example, that theplate 21 is formed with radially directed lower portions in one, two or three directions instead of in four. - The amplitude of the sinus shape, furthermore, can be levelled from the
periphery 22 of the plate to theconic portion 17 in a manner other than successively or linear. - Such modifications are regarded comprised in the invention.
- In Figs. 6 and 7 additional embodiments of the
plate 15 are shown, which in Fig. 6 is designated by 33 and in Fig. 7 by 34. Theplates 33 and, respectively, 34 are shown in a section corresponding to the section B-B in Fig. 2. Theplates - In Fig. 6 the
plate 33 is designed so that its height increases successively with the distance from its centre. The height increases substantially close to the periphery 35 of theplate 33, resulting in that the force required for moving the lever from its non-operative position increases with increasing deflection of thelever 3 and increases substantially when thesleeve 13 approaches the periphery 35 of theplate 33, i.e. at a great deflection of thelever 3. - In Fig. 7 a
plate 34 is shown, which is designed so as to have a substantiallyplane portion 36, whereafter in radial direction the height of the plate increases substantially close to itsperiphery 37. Owing to this design, the force required for moving thelever 3 from its non-operative position increases substantially first when thesleeve 13 approaches theperiphery 17 of theplate 34. - The features mentioned in the introductory portion as characteristic of the in1ention,thus, result in a simple and sturdy structural design, which besides renders it possible to form the characteristics of the force required for moving the lever in such a manner, that the characteristics is adapted to different purposes. A further advantage of the invention is, that the structural height from the
instrument panel 12 and downward of a manipulator is reduced substantially compared with known manipulators, because the spring arrangement is located above the instrument panel. - Different modifications of the invention have been mentioned above. The device according to the invention can be modified additionally without abandoning the invention idea.
- The invention, thus, must not be regarded restricted to the embodiments referred to above, but can be varied within the scope of the attached claims.
