Description

[0001] FOOT PEDAL LOCKING SYSTEM

[0002] Field of the Invention

[0003] The present invention relates to a foot pedal locking system which restricts the movement of the pedal at a certain angle.

[0004] In particular, the present invention relates to a stepped foot pedal locking system for controlling the crusher apparatus on construction machines, which is mounted under the pedal and restricts the movement of the pedal at a certain angle, so that the pedal is used in the same position each time the pedal is pressed.

[0005] State of the Art

[0006] Today, some work machines use a locking system on the foot pedals for more efficient and correct use of the work done. The mentioned locking systems aim to restrict the movement of the pedal at a certain distance so that the pedal remains in the same position every time the pedal is pressed.

[0007] In the state of the art, there are usually structures that allow the position to be determined only by the operator's habit without a physical limit on the foot pedal. In this case, the operator has to make many attempts to set the desired position.

[0008] In the known state of the art, there are also position determination mechanisms with electronic sensors. However, these mechanisms are costly. However, their structures are complex and mould production and special production parts suitable for the mould are used in the manufacturing processes.

[0009] As a result of the researches made on the subject, document No TW201302523A is encountered. Mentioned document relates to a brake pedal lock for a car. However, there is no pedal system suitable for construction machines that can be locked gradually in the state of the art.

[0010] Another document encountered in the literature is the document numbered US6182781 B1. The document concerns a pedal locking device for loaders. The present art discloses a loader pedal locking device that can prevent accidental up / down movement and unwanted tilting of a boom. Specifically, however, there is no pedal mechanism that can be gradually locked. As a result due to the abovementioned disadvantages and the insufficiency of the current solutions regarding the subject matter, a development is required to be made in the relevant technical field.

[0011] Object of the Invention

[0012] The present invention aims to solve the abovementioned disadvantages by being inspired from the current conditions.

[0013] The main object of the present invention is to provide a foot pedal locking system which is used under the pedal used for controlling the crusher apparatus, especially in construction machines, which restricts the movement of the pedal at a certain angle and gradually ensures that the pedal is used in the same position each time the pedal is pressed.

[0014] A further object of the present invention is to provide a pedal locking system which is easy to manufacture and install.

[0015] Another object of the present invention is to provide a pedal locking system which is not dependent on the operator's habits and therefore does not cause any occupational accidents.

[0016] In order to fulfil the aforementioned objects, the present invention relates to a foot pedal locking system which is mounted underneath the pedal used in vehicles, and in particular in construction machinery, and which restricts the movement of the pedal at a certain angle so that the pedal is gradually used in the same position each time the pedal is pressed, characterized in that, it comprises the following;

[0017] • A base plate forming the body of the foot pedal locking system and enabling said system to be mounted on the vehicle,

[0018] • A pin plate mounted on the base plate, which allows the pedal to be gradually held at a level,

[0019] • A lock pin that locks and secures said pin plate after height adjustment with the pin plate and

[0020] A centre pin for connecting the pin plate to the base plate The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description made with reference to these drawings and therefore the evaluation shall be made by taking these figures and the detailed description into consideration.

[0039] Detailed Description of the Invention In this detailed description, preferred embodiments of the inventive foot pedal locking system (A) are described only for the purpose of a better understanding of the subject matter.

[0040] The inventive foot pedal locking system (A) as shown in Figure 1 essentially comprises the following; a base plate (1), which forms the body of the system and enables said system to be mounted on the vehicle, a pin plate (2) mounted on the base plate (1), which allows the pedal to be gradually held at a level, a lock pin (3) which, after height adjustment with the pin plate (2), locks and secures said pin plate (2) and a centre pin (4) for connecting the pin plate (2) to the base plate (1).

[0041] One embodiment of the inventive foot pedal locking system (A) includes adjustment holes (2.1) on the pin plate (2) for locking the lock pin (3) to the pin plate (2), and for gradually adjusting the height of the pedal (10) to the desired level. The adjustment holes (2.1) are at least one and the lock pin (3) is inserted into these holes to ensure that the pin plate (2) remains at the desired level.

[0042] An embodiment of the inventive foot pedal locking system (A) comprises a circlip (5) for locking the centre pin (4) to the base plate (1), a wedge (6) connected to the pin plate (2) on which the pedal (10) is pressed on the locked system, and at least one support plate (7) welded to said base plate (1) to increase the strength of the base plate (1). It further comprises a wedge plate (8), which is positioned between said wedge (6) and the pin plate (2), and which provides the bearing of the wedge (6) to the pin plate (2). It also has a bearing bush (9) which provides the necessary bearing to ensure that the pin plate (2) rests on the centre pin (4) at the desired location.

[0043] The assembly and use of the inventive foot pedal locking system (A) is as follows:

[0044] The base plate (1) is mounted on the foot pedal locking system (A) to be used on the machine. By means of the centre pin (4) and the bearing bushes (9), the pin plate (2) is mounted on the base plate (1). The circlip (5) locks the centre pin (4) to the base plate (1). The support plates (7) add strength to the base plate (1) and prevent the base plate (1) from bending under extreme conditions. The wedge plate (8) is welded to the pin plate (2) and the wedge (6) is mounted on the wedge plate (8). After the desired setting is made, the foot pedal locking system (A) is prepared for use by inserting the lock pin (3) into the base plate (1).
