1) Title of the invention
Universal Repair Stand for Cockpit Instruments.
2) Field of invention
It is basically a mechanical engineering design combined with add on features to make a versatile repair stand used for providing easy mounting and 360 degrees operational freedom while carrying out repair of cockpit instruments.
3) Use of invention
This invented Universal Repair Stand for Cockpit Instruments finds its applicability in all Instrument Laboratories where precision instruments are repaired, overhauled and tested.
4) Prior art
The cockpit instruments are repaired by positioning them on the work table which is normally at a height of 750mm from the floor. The technician has to bend over the table to carry out the repair of the instrument.
5) Draw backs of prior art
There are certain shortcomings in the prior art way of repairing precision instruments as mentioned below:
Lack of rotational freedom while carrying out the repair of precision instruments.
Difficulty in positioning the instrument under test.
Accessibility to all components while doing repair becomes a major issue.
Due to bending over the work table while servicing the aircraft instruments for a longer duration, the technicians were prone to get back pain on the longer service.
■L /

It makes the work table to be clumsier and housekeeping was affected badly. Separate eye loop is required while carrying out the precision repair work.
6) Comparison between prior art and present invention
• This invented Universal Repair Stand for Cockpit Instruments design has a platform to mount any type of instrument for testing or repair.
• Universal Repair Stand for Cockpit Instruments consisting of two knuckle joints with 360 degree rotational freedom.
• The main significance of the design is its ease in installation, repair, testing and removal of units under test.
• It also minimizes the draw backs mentioned in the previous paragraph to a greater extent.
7) Aim of the invention
The Universal Repair Stand for Cockpit Instruments is a fixture that is useful for holding any precision instruments during its testing, repair and adjustments. The stand can be kept on any flat surface while carrying out the repair work. Any cockpit instrument can be easily clamped on to the stand by pulling the free side of the clamp which is spring loaded. The knuckle joints with rotational freedom allows for the manipulation of the Unit Under Test to aid in the technician in placing the work at various angles. The Magnifier becomes handy while inspecting minute parts during repair. The vibrator provides the necessary vibration for the UUT while testing. The small flexible LED lamp provided necessary illumination to the area of focus.
8) Summary of the present invention
Cockpit Instruments plays a vital role to flight safety. In order to maintain the cockpit instruments in a ready to use and healthy condition, these are to be tested and calibrated periodically.

The role of an instrument technician comes crucial at this juncture to test, calibrate, service and repair instruments thus to maintain high quality products.
There are two key factors needs attention:
a) Human ergonomics
The cockpit instruments are repaired by positioning them on the work table which is normally at a height of 750mm from the floor. The technician has to.bend over the table to carry out the repair of the instrument.
b) Quality of work
It is pertinent to mention that the instrument, which is being repaired, has to be positioned at various angles to get a better view as well as easy access to minute and precision components.
Continuous thinking on the above two issues led to the design and invention of a Universal Repair Stand for Cockpit Instruments. This invention comprises a base, a knuckle joint with 360 degree rotational freedom, a magnifier, a LED flexible lamp, a vibrator and a spring loaded instrument holder. The knuckle joint is rotatably mounted to the heavy base. A spring loaded instrument holder is fixed to the top plate of the knuckle joint. A rotatable magnifier is fixed to the top plate. A vibrator is fixed to the top plate to provide necessary vibration for the UUT while testing. Also the Universal Repair Stand for Cockpit Instruments comes with a flexible LED light.

10) Statement of invention
Any cockpit instrument can be easily clamped on to the stand by pulling the free side of the clamp which is spring loaded. The knuckle joints with rotational freedom allows for the manipulation of the UUT to aid in the technician in placing the work at various angles. The Magnifier becomes handy while inspecting minute parts during repair. The vibrator provides the necessary vibration for the UUT while testing. The small flexible LED lamp provided necessary illumination to the area of focus. This invention also minimizes the health hazards associated to working of technician by bending over the normal work table during repair of precision instruments.
