[0012] The invention relates to a handle lock assembly (100) suitable for use in cabinet covers. The handle lock assembly (100) comprising a main body (20) with an arm connection housing (21); an arm (10) located along a longitudinal axis of the main body (20) and supported at one end; and a lock plug (30) on the arm (10), which is suitable for locking in such a way to limit the movement of the arm (10). Said handle lock assembly (100) comprises at least one arm wheel (15) connected with the arm (10) and movable within the arm connection housing (21) simultaneously with the movement of the arm (10); at least one movement transmission member (17) having teeth (18) thereon and connected with the arm wheel (15) and positioned to convert the rotational movement from the arm wheel (15) to the linear movement; and at least one sealing member (40) positioned within the arm connection housing (21), configured and sized to be in circumferential contact with the inner wall (22) of the arm connection housing (21). The arm wheel housing (16) on the arm wheel (15) is coupled with the arm pin housing (25) and the arm pin (24) passes therethrough and forms the axis of rotation.

[0013] According to the present invention, the handle lock assembly (100) in the form of a lock structure is arranged to be resistant to external factors. One of the greatest advantages of the invention is that the hollow arm connection housing (21) connecting the arm (10) and the main body (20) is completely closed in order to impart a sealing feature.

[0014] As can be seen in Figs. 5a and 5b, said sealing member (40) comprises a first portion (41) and a second portion (42). In a possible embodiment the sealing member (40) is a single piece and the first portion (41) and the second portion (42) are integral with each other. Said first portion (41) includes a wheel housing (44) extending in the direction of the longitudinal axis of the sealing member (40) and in which the arm wheel (15) can move. Thus, the arm wheel (15) is also securely enclosed. The wheel housing (44) is selected to have a thickness that will allow the arm wheel (15) to move freely. On the other hand, there is at least one connection hole (43) on the second portion (42) to fix the sealing member (40) to the main body (20). As can be seen in Fig. 5a, there are two connection holes (43) on the second portion (42). As can be seen in Fig. 1, there is a sealing cover (45) having at least one connection protrusion (46) to couple with the connection holes (43). In particular, the sealing cover (45) to cover the second portion (45), ensures that the sealing member (40) is securely connected to the main body (20). As can be seen in Fig. 2, there is a fixing member (13) that is to be passed through the connection hole (43) on the second portion (42) and the connection protrusion (46) on the sealing cover (45). In this way, the sealing cover (45), especially the second portion (42) is completely surrounded and the connection is realized through the second portion (42). Preferably, the sealing member (40) is made from a flexible material which bends and returns to its original shape and the sealing member (40) is preferably water resistant. Thus, the arm wheel (15) is especially prevented from getting wet, corroded and losing its function over time. It can be said that the arm wheel (15) acts as a pinion gear. As can be seen in Fig. 5b, the sealing member (40) has an alignment housing (47) that is to be coupled with a protrusion in the arm connection housing (21) of the main body (20), other than the connection holes (43).

[0015] The handle lock assembly (100) comprises an arm pin (24) that allows the arm (10) to be supported on the main body (20) by being passed through at least one main body pin housing (23) in the arm connection housing (21) and through the arm pin housing (25) on the arm. In this way, the arm rotates around the rotation axis that is created where it is supported. As can be seen in Fig. 2, said arm (10) is rotated around the arm pin (24) and raised in the upward direction.

[0016] Again, as can be seen in Fig. 1, there is a support member (14) provided at said arm (10) and suitable for compression in such a way that it contacts an upper surface of the main body (20) when the handle lock assembly (100) is in the closed position. The support member (14) is made of a cylindrical and flexible material, and it is compressed to exhibit a spring effect when the handle lock assembly (100) is in the closed position. Due to such compression, once the lock tongue (32) is pulled back by the lock plug (30), the support member (14) allows the arm (10) to move away from the main body (20) with the effect of the compression, and provides an easy opening opportunity. Inside the inner wall of the arm (10), there is a connection protrusion to which the support member (14) can be attached. Using a suitable fixing member (13), the support member (14) is attached to the connection protrusion. In a preferred embodiment of the invention, said support member (14) is compressed on the sealing cover (45) when the handle lock assembly (100) is in the closed position.

[0017] The lock plug (30), which is inserted in a lock plug housing (33) on said arm (10), comprises spring-loaded encryption pins arranged in accordance with the key to be inserted therein, like a cylinder lock structure. When the user inserts an appropriate key from the key hole (31) in the lock plug (30), the encryption pins take the appropriate position and allow the key to be turned and the lock tongue (32) to be pulled out of the hole where is inserted, and the arm (10) is lifted up. In order to insert the lock plug (30) into the lock plug housing (33), there is a lock plug assembly protrusion (11) on the inner side of the arm (10), through which the arm assembly hole (12) is located. Said lock plug housing (33) comprises a first type connection cavity (35) and a second type connection cavity (36), in different sizes and shapes, in such a way to allow different types of lock plugs (30) to be inserted thereto. The first type connection cavity (35) is located on the longer lateral inner wall, and the second type connection cavity (36) can be located on another inner wall adjacent to the lateral wall.

[0018] As can be seen in Fig. 1, the lock plug assembly hole (34) on the lock plug (30) is aligned with the lock plug assembly protrusion (11) and is fixed to the arm (10) with a suitable fixing member (13) passed therethrough. In addition, there is a fixing member (13) that allows the lock plug (30) to be held in the arm (10) by being passed through the lock plug assembly hole (34) and the arm assembly hole (12). In this way, every type of lock plug (30) in different types of structures having a lock plug assembly hole (34) thereon is fitted into the arm (10) in a compatible manner. The lower surface of the lock tongue (32) is also curved in a convex manner, and while the arm (10) is being closed, the lock tongue (32) is shifted with this surface and is inserted into the appropriate housing.

[0019] Referring to Fig. 4, the transmission member (17) is a rack gear that will interact with the arm wheel (15). The transmission member (17) includes locking teeth (19) that extend partially outward from the main body (20) and enable the arm lock (10) to perform the locking and unlocking operations. The teeth of the arm wheel (15) and the locking teeth (19) of the transmission member (17) match and provide linear movement of the transmission member (17). The transmission member interacts with the opposite locking member that will be moved by the arm lock (10).

[0020] The handle lock assembly (100) described within the scope of the invention will not only be effective against sealing, but also includes a dust cover (50) surrounding the lock plug (30) so as to be more durable in places where it is exposed to harsh conditions such as dust, dirt and corrosion. The dust cover (50), which has an outer surface to coincide with the outer surface of the arm (10), especially restricts the access to the key hole (31). There are at least two opposing claws (51) to ensure easy installation of the dust cover (50). With these claws, it is easily attached to the arm (10).

[0021] The sealing member (40) may be made of a rubber material. The handle lock assembly (100) presented within the scope of the present invention can be used on cabinets or panel doors. The proposed handle lock assembly (100) is arranged especially suitable for use in box or cabinet covers.
