Description

MECHANISM THAT CAN MOVE HORIZONTALLY FOR ENABLING ARTIFICIAL
JOINT MOVEMENTS
Technical Field
The invention relates to a mechanism that can move horizontally, suitable to be used in hydraulic artificial joint mechanisms having hydraulic movement elements.
Prior Art
Artificial joints are defined as mechanisms that allow the user to maintain normal life functions when attached to the limb part, by imitating the natural movement of the organs having joints.
Artificial joints consist of a movement mechanism, designed to allow joint movement and, movement limiting elements that enable the movement to be limited in order to simulate joint movement.
The most important example that can be given to mechanisms that are used to artificially simulate joint movements is mechanisms that provide hydraulic motion.
The patent application numbered WO2014137664 describes a prosthesis foot/ankle including a hydraulic motion mechanism. The ankle mechanism subject to the invention consists of 3 main components according to the description of the application. These components are, a casing to attach the prosthesis foot, an ankle component adapted to be attached to a pylon and a piston moving in a curved cylinder during walking. Volume is also reserved within the prosthesis mechanism for the movement of the piston that can move vertically. The piston can move inside the volume created vertically.
The patent application numbered US 2013173021 describes a prosthesis foot mechanism. According to the description of the related application, the artificial joint system can control the operation of the system electronically by sensor/sensors on the ankle. The system has two piston systems as rear and front. The piston systems are designed vertically and they operate on the basis that a dynamic volume moves in and out of a motionless volume. This situation makes it imperative for the system to be provided with additional piston housing for allowing the piston movement .
The patent application numbered US 2015066154 describes a foot prosthesis comprising a pair of prosthetic members movably connected to each other to allow movement of pairs of prosthetic members relative to each other. Prosthetic members are connected to each other via a hydraulic actuator or damper via a hydraulic fluid chamber. A hydraulic piston is movably disposed in the hydraulic chamber and coupled to another of the pair of prosthetic members.
The product that is subject to the application numbered US 2015066154, cannot be operated without having housings in the volume corresponding to the dimensions of the piston rod. The piston mechanism is positioned in an angle but not perpendicular to the prosthetic foot so as not to enlarge the prosthetic volume. However, the dimensions of the mechanism have not been reduced sufficiently. The patent application numbered US 2014324190 describes a system and a method related to leg movement. In the example of the invention, a system such as a prosthesis or an orthosis is adjusted by an active control actuator that regulates the angle between a foot unit and a lower leg member.
The product that is subject to the related application and prosthesis foot mechanism is controlled electronically thus enabling the system to operate in a more controlled manner. However, the system is required to consist of a piston movement volume to enable piston movements, like other systems known in the prior art .
Artificial joint systems that operate vertically and that consist of hydraulic systems, require the hydraulic volume to operate and the system body cannot be made smaller because of complex structures. Larger artificial joint structures do not have the ergonomics of usage and, they are not practical to use due to the weight increase.
When vertical hydraulic systems are used, power losses occur during the operation of the system. This situation affects the performance and efficiency of the system.
Problems that the Invention Aims to Solve
The aim of this invention is to develop an artificial joint system that resolves adversities that occur because of volume changes within the hydraulic system during movement of the piston rod in and out of the hydraulic system. The aim of this invention is to develop an artificial joint mechanism, suitable for ergonomic usage due to being reduced both in volume and weight.
The aim of this invention is to develop an artificial joint mechanism that does not complicate the hydraulic system while regulating volume changes created within the hydraulic system.
Another aim of this invention is to develop an artificial joint mechanism in which power loss is minimized during power transmission .
Another aim of this invention is to prevent power loss due to transmission organs and to reduce the dimensions of the artificial joint mechanism by eliminating the required transmission organs for power transmission.
Another aim of this invention is to develop an artificial joint mechanism that has a suitable structure for many different fields of application.

Description of the Invention
The invention relates to an artificial joint movement mechanism comprising a control unit (2) consisting of a lower-body (4) and an upper-body (3), which operate in relation to each other while being connected to the base (1) .
The upper-body (3) provides the transfer of movement from the part of the limb to which it is connected to the lower-body (4) .
The lower body (4) comprises a circular motion element (5) and a horizontal movement element (6) . The circular motion element (5) and upper-body (3) are connected to each other with a shank enabling the transfer of movement. Therefore, the motion transferred to the upper-body (3) via a limb part, can also be transmitted to the circular motion element (5) . The upper-body (3) is designed to be able to move partially circular around a pivot point connected to the base (1) . In Figure 2, the upper body (3) is shown in the front position when moving relative to the lower body (4), and in the rear position in Figure 3.
The circular motion element (5) is fixed at a point to the lower body (4) such that it can be rotated by the forward and backward movement of the upper body (3) . The rotational movement of the circular motion element (5) around the fixing point is precluded to move in a full circle around the fixing point.
The circular motion element (5) is related to the vertical movement element (6) in a way that it can transmit movement. To enable motion transfer, circular movement element (5) includes a circular motion element connection component (5.1), and a horizontal movement element (6) includes a horizontal movement element connection component (6.1) .
According to figure 4, the circular motion element connection component (5.1) is in the form of a protrusion on the circular motion element (5) . Similarly, the horizontal movement element connection component (6.1) is in the form of a recess on the horizontal movement element (6) .
With the movement of the circular motion element (5), the circular motion element connection component (5.1) can transfer motion, by contacting the horizontal movement element connection component (6.1) .
According to an embodiment, the horizontal movement element (6) is a piston that is a part of the hydraulic mechanism. To limit the movements of the horizontal movement element (6) on the horizontal plane (base extension plane), it has been connected to a damping element (7) at least from one section. Since the limited movement of the artificial joint mechanism is desired, as in natural joint systems, the damping element both restricts motion and provides a more consistent movement of the system similar to natural joint movements.
According to figure 2, the damping element (7) is located between the horizontal movement element (6) and the cover (8) . At least one compressing volume (10) is created for the damping element (7) to be able to operate between the cover (8) and the horizontal movement element (6) .
The damping element (7) is in the form of spring according to figure 2. With the movement of the horizontal movement element (6) in the direction of the cover (8), the spring is compressed by the movement of the horizontal movement element (6), the force created on the spring is eliminated and the spring is released.
In different embodiments of the invention, structures consisting of different flexible materials that can be compressed and released can be used as a damping element (7) .
According to an application related to the invention, the damping element (7) can be produced by using elastomer materials such as polyurethane, silicone, etc.
The horizontal movement element (6) is connected to the lower body (4) by means of a bearing element (9) from a section that is not in contact with the damping element (7) . In Figure 5, the lower body (4) has a lower-body upper element (4.1) on its surface to which it is connected to the upper body (3) . The lower body upper element (4.1) eases the movement of the upper body (3) on the lower body (4) by forming an upper surface in concave form.
According to figure 5, the body upper element (4.1), is mounted to the lower body (4) via connection element/elements (11) . Artificial joint mechanism subject to the invention can be used as a prosthetic component attached to a base (1) as it is described in the aforementioned figures, it is also suitable for forming all or part of an artificial joint mechanism connected to different limb parts without having a base (1) .
