range can be narrowed by defining new physical minimum or maximum values, when this adjustable setting is terminated, the control component can move within the pre-determined physical values again, in order to set new physical minimum or maximum values, a forced connection must be established between the control component and a component which, owing to its structure, ensures the new physical minimum or maximum values, this component has a standstill position and it can move only in one direction because of the control component, thus, the component restricts the adjustable state of the control component, when the forced connection is terminated, the component is pushed back to its standstill position by a force, which makes it possible to establish a new physical limit, if the component is allowed to move toward the maximum value of the parameter adjustment device, a new physical minimum value can be set and if the component is allowed to move toward the minimum value, a new physical maximum value can be set at the moment the forced connection is established. 2. . a parameter- adjustment device as in claim 1. where in the parameter-adjustment device is a rotary

potentiometer, in active position, a forced connection is established between the modified potentiometer control knob and the rotating part of the modified nut, this connection ensures that the modified potentiometer control knob and the rotating part of the modified nut are able to move only together in active position, since the actual value of the potentiometer at which the connection is established will be the new minimum or maximum value of the potentiometer value range, thus, when a new minimum value is set, the control component of the potentiometer can only move between its own maximum and the newly set minimum values, when a new maximum value is set, the control component of the potentiometer can be set between its own minimum and the newly set maximum values, the forced

Technical field of invention
The object of this invention is a device which is capable of narrowing or fixing the value range of a parameter- adjustment device.
The value range of a parameter-adjustment device can be narrowed by setting any value between the original minimum and maximum values of a parameter-adjustment device, as a new minimum or maximum value, by the apparatus, which value can be changed immediately on demand. Present invention can be used with parameter-adjustment devices, potentiometers, rotary or slider potentiometers
Background of invention
The closest one to present invention in terms of technology, in document GB 2 294 747 operates rather differently and is not capable of meeting the above mentioned criteria.
With this solution the minimum value of the volume range of the light adjustment switch can be altered so that the value of light to be emmitted when turning the light on should be preset on demand. This result is achieved by equiping the rotatable adjustment knob - more specifically the axis of the potentiometer adjusting the light volume - with a removable rotary knob that has an internal bumper comes into contact with the external knock point of the light adjustment switch allowing it only to be turned to a higher level of volume, resulting it to only provide access to adjust the volume of light to a higher degree.
Insufficiency in the known solution is the minimum brightness setting item is only suitable for changing the position of the dimmer switch by disassembly , and the change can only be performed by professionals. Another shortcoming is that the parameters used in the existing structure and adjustment devices are not directly adaptable, but after the positioning element's (rotary axis), proper conversion
The task present invention performs is to narrow the value range of a parameter- configuration device by setting any value within the configurable range and by setting new minimum and maximum values, which can be changed any time. Summary of the invention
Based on this realisation the intended operation can be realised without any alteration on the parameter adjustment device by installing the apparatus afterwards, in a way that a forced connection can be achieved between the adjustment part of the parameter adjustment device and a part moving on a line determined by a starting and an ending point., in case of terminating the forced connection the part will return to the begining level of its scale, by this making it possible to set a new minimum or maximum level.
The object of this invention is a device which is capable of narrowing or fixing the value range of a parameter adjustment device. The value range can be narrowed by setting any value between the parameter adjustment device 's own minimum and maximum, by creating a forced connection between the adjusting part of the parameter adjustment device and the part moving on a circular scale between a starting and an ending point, that part returns to its starting position whenever the connection is broken, making it possible to set a new value.
In case of a potentiomter, a modified nut is attached to the threaded collar or other fix part of the potentiometer. The modified nut consists of a lower fixed part and an upper rotating part. The rotating part can only move on a rotating scale restricted by built-in-stops integrated into its lower fixed part and upper rotating part.
In a standstill position the stop of the rotating part is pulled to the stop of the fixed part provided by a force that can be achieved by a spring, magnetic force or flexible material, so the rotating part can only be turned one direction from its standstil. The rotating part can turn clockwise or counterclockwise depending on the direction of the returning force. The spring is attached to the fix part of the modified nut, with its other end attached to the rotating part. If the rotating part is set to be able to turn towards the maximum value of the potentiometer from its starting standstill, than a minimum level can be set, and when it can be turned towards the minimum value of the potentiometer a maximum level can be set.
When the rotating part is turned by applying a force to it, it will return to its starting standstill position when the force is not applied any more.
The forced connection can be broken at any time at a desired position of the potentiometer or can be established immediately. A modified potentiometer control knob is attached to the rotating shaft of the potentiometer which is unable to rotate related to the shaft but can move parallel to it. The ability to move parallel to the shaft ensures the active or inactive state of the device.
In inactive state, the modified potentiometer control knob can be rotated independently of the rotating part of the modified nut, between the potentiometer's own minimum and maximum values.
In active state, a forced connection is established between the modified potentiometer control knob and the rotating part of the modified nut. From that time on, the modified potentiometer control knob and the modified nut can rotate only simultaneously. When the modified potentiometer control knob and the modified nut are connected, the actual value of the potentiometer will be the new minimum or maximum value of the potentiometer value range. Thus, when a new minimum value is set, the control component of the potentiometer can only move between its own maximum and the newly set minimum values. When a new maximum value is set, the control component of the potentiometer can be set between its own minimum and the newly set maximum values.
The value range of potentiometers are located between two designated minimum and maximum thresholds. If the activation of the apparatus takes place between these minimum 0 and maximum 10 values, than the set value will be the new minimum of the value range of the potentiometer, if the rotating part is allowed to move towards the maximum value of the potentiometer. For example by activating the device at value 5 of the potentiometer, we limit the interval of the potentiometer between values 5 and 10. after deactivating, we immediately get a chance to set a new minimum value.
In case of a linear potentiometer the operation described above can be achieved with the modification that the circular scale is modified to a linear scale while the rotating movement is to be modified to a linear movement.
If we forcedly connect the adjusting part of a potentiometer to a fixed immobile part , the actual position of the potentiometer will be fixed ont he actual value. Breaking the connection new value can be set ont he potentiometer. When the connection is stopped, a new value can be set on the parameter- adjustment device.
If the rotating shaft of the potentiometer can also move axially as well, the active and inactive status can be achieved this way and it makes it possible to place the rotating part on a restricted scale inside the potentiometer.
The inner structure within the parameter adjustment device would be the easiest to create during the manufacture of the parameter adjustment device.within the parameter adjustment device itself with altering its internal structure
The device of the present invention provides quick, immediate and simple method to narrow the value ranges. It is simple to install, can be implemented at a low price and posterior installation is possible as well. The device can be applied in the following fields
- guitars, electric musical instruments, musical instalment amplifiers, effects,
- sound systems, amplifiers, mixing consoles,
- consumer electronics, Hi-Fi systems,
- faucets, thermostats,
- fishing reels,
- any device on which parameters need to be set.

The volume control potentiometer of a guitar can set a value only between the minimum and the maximum value and has two fixed ending points.
To use the object of the invention, the potentiometer control knob has to be removed, the nut which fixes the potentiometer has to be replaced with the modified nut of the device.
The device, object of the invention, consist of the following components:
Figure 1 ,an axonometric drawing of the device from above
- 1 potentiometer shaft, 2 lower fixed nut, 3 the built-in stop of the lower fixed nut, 4 pulling spring, 5 rotating shim, 6 the built-in stop of the rotating shim, 7 external knob part, 8 pressing spring, 9 internal knob part, 10 locking cap, 11 grub screw.
Figure 2 ,an axonometric drawing of the device from below
- 1 potentiometer shaft, 2 lower fixed nut, 4 pulling spring, 5 rotating shim,
6 the built-in stop of the rotating shim, 7 external knob part, 8 pressing spring, 9 internal knob part, 10 locking cap, 11 grub screw.
The components of the modified nut:
Figure 3 ,a lateral view cross-section drawing of the modified nut
- 2 lower fixed nut
- 5 rotating shim
- 4 pulling spring: it provides force between the rotating shim and the lower fixed nut.
Figure 4 an axonometric exploded drawing of the modified nut
There are built-in stops 3 and 6 built in the lower fixed nut 2 and the rotating shim 5. One end of the pulling spring 4 is attached to the lower fixed nut and the other end is attached to the rotating shim.
In standstill position, the rotating part can rotate toward the maximum value of the potentiometer (clockwise) and the pulling string 4 presses the built-in stop of the rotating shim 3against the built-in stop of the lower fixed nut 6. This build-up of the modified nut allows setting a new minimum value.
So, the rotating shim can move only to clockwise (right) along the line determined by the built-in stops 3 and 6.
When the rotating shim 5 is rotated to clockwise (right) and then released, the rotating shim returns to its standstill position.
A modified potentiometer control knob is attached to the shaft of the potentiometer 1. The components of the modified potentiometer control knob:
Figure 5 an axonometric exploded drawing of the modified potentiometer control knob
- 9 internal knob part (it is driven in the axial opening of the external knob part 7, by a form- locking connection it is protected against rotation and is provided with an axial threaded bore.
- 7 external knob part (which rotates together with the internal knob part 9 and can be moved axially as well and it is provided with an axial bore)
- 8 pressing spring (it presses the external knob part toward the modified nut in relation to the internal knob part).
- 10 locking cap: it is connected to the external knob part (with a form-locking connection, glue or assembling), its edge helps its ability to move axially.
- 11 grub-screw (it fixes the internal knob part to the 1 potentiometer shaft)
The operation of the device:
Figure 6 ,a lateral view cross-section drawing of the modified potentiometer control knob when activated
The pressing spring 8, then the internal knob part 9 and the locking cap 10 are placed in the external knob part 7 of the modified potentiometer control knob. The locking cap is connected to the external knob part (form-locking connection, glue etc.).
The pressing spring provides pressure between the internal and the external parts.
Figure 7 , lateral view axonometric drawing of the device when inactivated
In inactive (pulled up) position, there is no connection between the rotating shim 5 and the external knob part 7. The inactive position or state can be established by moving the external knob part away from the rotating shim axially as long as it snaps over the lamina ribs of the internal knob part.
The inactive position is established when the external and the internal knob parts are connected. The laminae ribs of the internal knob part lock the inactive position by snapping over the external knob part.
Figure 8 ,a lateral view axonometric drawing drawing of the device when activated
In active (pressed down) position, a forced connection is established between the 5 rotating shim and the 7 external knob part . In active position, when the axial connection between the 9 internal and 7 external knob parts are stopped, the 8 spring presses the 7 external knob part toward the 5 rotating shim in relation to the 9 internal knob part as long as the forced connection to the 5 rotating shim is established. After the connection is established, 5 the rotating shim and the 7 external knob part can be rotated only together. The connection is ensured by pressing force of the 8 spring and the adhesion of the surfaces: The adhesion is established by strengthening the adhesion (roughening, rubberizing or painting the surfaces).
If the device is at the maximum value of the potentiometer in inactive position and the device is activated, the minimum value will be the maximum value at the same time, since the control component of the potentiometer is unable to rotate counterclockwise any more.
If the potentiometer is at the minimum value when the device is activated, no change can be seen compared to the original operation since the new minimum value is the same as the old one.
If the device is activated when the potentiometer is between the minimum and the maximum values , the newly set value will be the new minimum value of the potentiometer.
