Definitions

• the invention relates to a control lever connection system that prevents the user from involuntarily contacting the control lever that controls the movements of the construction machine during the operation of the construction machine and increases the operation safety of the construction machine.
• the invention relates to a control lever connection system in construction machines that are used particularly for digging and/or loading operations that prevents the user from involuntarily contacting the control lever when the control lever is not being used, the said control lever being located close to the user's seat and allowing the movements of the construction machine to be controlled, and that prevents accidents or faulty operations that may occur during the operation of the construction machine.
• control levers located close to the seat of the user are used for digging, transporting the excavated material or loading it on a truck.
• two control levers are generally used, which are integrated into the seat or armrests of the user and located in a position within the reach of the user's hand. These control levers are activated when the user makes the machine ready for digging or loading, and they allow the user to control the movements of the machine to carry out digging or loading operations. When the user brings the work machine to a suitable position for the digging process, both of these control levers become active and usable.
• This situation causes a decrease in the maneuvering and mobility ability of the user making it difficult for the user to control the construction machine, disrupting the work ergonomics at best, and at worst, causes the user to lose control of the construction machine, resulting in dangerous situations for both the user and the surrounding objects or people.
• control lever suitable for use in construction machines such as crawler excavators or digging machines and which allows controlling of the movements of the construction machine by an electronic control system.
• the said control lever includes a control rod that can move in more than one direction, an activation element that allows the movements of the construction machine to be directed by activating the control lever or prevents the movements of the construction machine from being directed by deactivating the control lever, and a sensor element which is in connection with the actuation element and allows sensing of the movement of the control lever and detection of the amount of its movement.
• control lever With the control lever described in the said document, the user's movement of the control rod is detected, and the control lever is activated, and the movements of the construction machine are controlled in accordance with the speed and amount of the user's movement of the control rod. It is also mentioned in the document that the control handle is placed in a position where the user's hand can easily reach it. However, the said document does not mention preventing the user's arm from involuntarily touching, snagging or hitting the inactive and/or unused control lever during the use of the construction machine.
• control lever system suitable for use in a construction machine such as an agricultural tractor.
• the said control lever system comprises a control panel containing control keys that enable the different functions of the construction machine to be controlled, a control rod connected to the control panel, suitable for moving in more than one direction and directing the movements of the construction machine.
• the system also includes a locking element that is associated with the control rod and prevents the control rod from being moved when not in use, and a support element located on the control rod that allows the user to rest his arm on the control rod.
• the said document does not mention preventing the user's arm from involuntarily touching, snagging or hitting the inactive and/or unused control arm during the use of the construction machine during the use of the construction machine
• control lever connection system that prevents the user from involuntarily contacting the control lever when it is not in use, the said control lever being located close to the user's seat and provides for the control of the movements of the construction machine, thus preventing accidents or faulty operations that may occur during the operation of the construction machine and improves operator ergonomics.
• the present invention relates to a control lever connection system that meets the requirements mentioned above, eliminates all disadvantages and provides some additional advantages.
• the main objective of the control lever connection system is to provide a control lever connection system that prevents the user from contacting the control lever, which provides for the controlling of the movements of the construction machine, when the control lever is not being used.
• Another objective of the invention is to provide a safe and effective control lever connection system which prevents the occurrence of work accidents or faulty operations by preventing the user's arm or hand from catching or hitting the unused control lever during the use of the construction machine.
• Another objective of the invention is to provide a healthy control lever connection system that improves the body ergonomics of the construction machine operator during the use of the construction machine.

• the body element (1) is connected to the seat (B) in such a way that the user can reach it easily. Afterwards, it is ensured that the support element (2) is connected to the body element (1) by means of the connecting element (3) and the control arm (A) is fixed on the transport element (2).
• the locking element (5) is separated from the fixation element (4) by moving the support element (2) and the control lever (A) connected with the carrying element (2) away from the user. Meanwhile, the support element (2) is rotated around an axis parallel to the ground and moved in the second direction by means of the connecting element (3).
• control lever (A) is moved away from the seat (B) and that the control lever (A) is brought to the second position in such a way that it makes an angle to the ground. In this way, when the control lever (A) is not in use, the user's arm or hand is prevented from catching or hitting the control lever (A).
• moving the support element (2) and the control lever (A) connected to the support element (2) to approach towards the user and rotating the support element (2) around the said axis through the connection element (3) accomplished the movement in the first direction.
• control lever (A) is moved towards the seat (B) and the control lever (A) is brought to a position easily accessible by the user. Afterwards, the control lever (A) is fixed at the first position through the locking element (5) holding onto the fixation element (6).
• the mentioned control lever connection system preferably comprises at least one trigger element (6) in the form of a movable latch, which is connected with the said locking element (5) and controls the attachment of the said locking element (5) to the said fixation element (4) and/or its separation from the said fixing element (4).
• the said control lever connection system preferably comprises at least one holding element (7) in the form of a handle, which is connected with said support element (2) and provides a gripping surface for the user to move the said support element (3) in said first direction and said second direction.
• control lever (A) that controls the movements of the work machine is connected to the user's seat (B), and the inactive and/or unused control lever (A) is removed from the seat (B) preventing the user's arm or hand from hitting the control lever (A).
