Definitions
- the invention relates to a pivoting support device, e.g. in the form of a medical examination unit, a table, a plate or the like, which in their relative position in relation to an object or a user in a horizontal or vertical plane is pivotable.
- a pivoting support device e.g. in the form of a medical examination unit, a table, a plate or the like, which in their relative position in relation to an object or a user in a horizontal or vertical plane is pivotable.
- the invention relates to a Examination turntable, as used in medical practices, hospitals, etc. for examinations is used in which the doctor and patient sit opposite each other and the examination table with the medical examination devices from one Rest position outside the examination area in the working position between Doctor and patient must be brought, as e.g. during ophthalmological examinations the case is.
- Such examination tables are usually at rest arranged to the side of the doctor's chair and are currently being made out of it Rest position brought into the working position by either using the appropriate parallel guides or on rollers from the side position in a position between doctor and patient is shifted, or else by swiveling the table around a pivot point.
- DE 38 32 844 A1 discloses an operating device holder for wheelchairs, consisting of a support arm attached to the wheelchair and a holder for the Control unit housing exists.
- the inclusion of the control unit is by means of a handlebar connected to the support arm and parallel to the handlebar is a transmission provided that a parallel adjustment of the recording when pivoting of the handlebar.
- the object is achieved according to the invention solved by a pivotable support device according to claim 1.
- both tooth lock washers have the same gear ratio, for example a positioning arm, which at its end is in an unchangeable horizontal position has to be held receptacle for holding devices or the like, in one vertical plane.
- the relative position of the positioning arm remains and the receptacle are the same, i.e., despite the pivoting of the The positioning piece remains with little positioning and with it the device in its given horizontal or any other given position.
- Another The advantage is that the positioning arm in any angular position without additional locking or detent is adjustable and that this setting can be made precisely. It is a stepless height adjustment of the receiving piece possible by the user in the working position Adjustment is extremely smooth. While not in use, the Positioning arm including the equipment arranged on it in a space-saving way and kept outside the work area become. A collision with other devices previously or subsequently used will occur thereby excluded.
- the positioning arm can be attached to a carrying device, e.g. a pillar, or at be attached to a wall support.
- a counterweight is provided, which in a advantageous embodiment is exchangeably attached to the support arm to the Inclusion of changing equipment with different weights in the To enable the receiving piece.
- the other end of the support arm 4 protrudes outwards from the bearing 3 and carries a toothed washer 8 on the top of the support arm 4.
- a fixed toothed disk 10 is attached.
- 10 runs a toothed belt 12.
- the transmission ratio of the two toothed pulleys 10 and 8 is 2: 1, i.e. the toothed pulley 10 is e.g. a tooth lock washer Z40, while the toothed disk 8 is a toothed disk Z20.
- the toothed disk 8 carries a carrier plate 6 and is rigidly connected to the underside of the carrier plate 6.
- the carrier plate is the table plate of a medical examination unit, on which various medical apparatus and devices (not shown) for medical examination of patients.
- the Table top 6, preferably made of wood, is through a plate 14 on its underside strengthened.
- Fig. 2 is a plan view of the support device of FIG. 1 with different Working positions of the examination unit are shown. Based on this figure the mode of operation of the carrying device according to the invention is described below become.
- A is the rest position of the examination unit and with B denotes the final working position of the examination unit.
- B denotes the final working position of the examination unit.
- the examination unit is at the beginning of the Examination in its rest position A, i.e.
- the table top 6 with its corners a, b, c, d lies outside the doctor-patient area, shown in the continuous Lines to, for example, preliminary examinations on the patient without disabilities approved by the examining unit by the doctor.
- the support arm 4 is in the position indicated by A.
- the carrier arm 4 With further rotation of the table top 6 counterclockwise the carrier arm 4 continues its rotation in the clockwise direction and reaches finally his working position B. In this working position B of the support arm 4 Finally, the table top 6 has its desired working position B between Doctor and patient reached and the examination can be carried out with the necessary equipment be continued.
- the process Upon completion of the investigation, the process will go in the opposite direction carried out, i.e. the table top is pushed clockwise at its corner d, which in turn moves the toothed disk 8 in the opposite direction and the rotation via the toothed belt 12 and the toothed pulley 10 onto the bearing 3 is transmitted, which brings the support arm 4 back to its rest position A.
- This rotation and pivoting movement of the table top 6 is determined by the predetermined opposite movement of the support arm 4 and the transmission ratio of the two toothed disks 8, 10 of 2: 1.
- the positioning arm 30 shown in FIG. 3 operates in the same way Principle of operation as the examination unit described above, however, here instead of a horizontal rotating and swiveling movement, a vertical rotating and Swivel movement carried out, which leads to a slightly changed construction.
- the positioning arm 30 is on a columnar support device 40 by means of a Bracket 41 attached.
- the bracket 41 can be moved vertically if necessary the column 40 may be attached to an even more variable height adjustment enable.
- a toothed disk 32 is rotatably attached to the holder 41.
- the Toothed washer 32 is also the fulcrum for one end of the positioning arm 30, the other end of which is formed with a further toothed washer 34.
- the second Toothed washer 34 is also the fulcrum for a receiving piece 36, which for Recording various devices and apparatus 37 is formed.
- the tooth lock washers 32 and 34 have the same gear ratio and are by one circumferential toothed belt connected.
- a counterweight 38 is arranged.
- this weight 38 is releasably attached for easy replacement to be able to make different counterweights when the receiving piece 36 is equipped with various weight devices.
- the rest position is also designated A in FIG. 3.
- the device 37 which is, for example, an optical eyeglass determination device can be in any pivot position of the positioning arm 30 in a horizontal Hold position. This is due to the same speed of rotation of both toothed disks 32 and reached 34.
- the positioning arm 30 from the rest position A in the clockwise direction rotated, the toothed disc 32 rotates with it, the rotational movement of which the toothed belt is in turn transferred to the toothed pulley 34. Since that Gear ratio of the two lock washers 32, 34 is 1: 1, both rotate Toothed washers 32, 34 with the same speed of rotation, so that the horizontal position of the device 37 during the entire rotary movement and of course also remains in the working position B of the positioning arm 30.
- the positioning arm 30 By arranging the corresponding counterweight 38 and through the toothed disc 32 is the positioning arm 30 in any angular position without additional locking or locking means can be set precisely. The same is true Angular position of the equipment 37 by the toothed disk 34 adjustable and remains in this position without additional locking or locking means.
- the pivoting support is applicable in various technical areas and not on the applications shown in the exemplary embodiments are limited.
- the Invention becomes an extremely smooth and harmoniously pivotable Carrying device provided that without changing the position of the seat Can be operated by the user and an extreme for the rotating and swiveling movement requires little space.
