HANDLE LOCK ASSEMBLY

Description

Technical Field of the Invention

[0001] The present invention relates to a linear acting handle lock assembly with an improved sealing feature.

Background of the Invention

[0002] It is known in the art that handle lock assembly structures, which are suitable for linear movement and have a handle that the user can move in the vertical direction, have been used for many years. Such handle lock assemblies are exposed to external factors, especially in the open air, and the working efficiency thereof may decrease as a result of rain, heat, temperature, etc.

[0003] A prior art publication in the technical field of the invention may be referred to as EP2476825 (A2), which discloses a lock mechanism comprising a main body accommodating a handle. Rotation of said handle activates longitudinal rods movable on a locking and unlocking direction with respective slots. Rotation of said handle is allowed upon operation of two locks in a sequence according to the present invention.

[0004] Another prior art publication in the technical field of the present invention may be referred to as TR 2019 04289 U5 among others, the document disclosing a lever lock for use in electrical-electronic cabinets, and cabinets, comprising a housing and a lever embedded in said housing and connected to said housing by means of a locking adapter to limit movement on said housing. The document further discloses that a sliding plate having a rotary wheel is disposed on the rear side of the sliding plate and in contact with internal gears formed on at least one inner edge of the rear side of the sliding plate.

[0005] Another prior art publication in the technical field of the present invention may be referred to as DE 201 07 170 111 among others, the document disclosing a bar lock for a lever bar lock for mounting in one or two rectangular openings in a thin wall, such as a door leaf. The document further discloses that a lock case that can be placed on one (inner) side of the door leaf and has devices for the axially displaceable mounting of at least one locking bar, and a pinion whose teeth mesh with matching perforations, incisions, indentations, or serrations of corresponding locking rod(s).

[0006] This type of vertical handle-operated lock assemblies may not exhibit sufficient resistance against sealing. Especially undesirable situations such as wetting and dusting of the gear structure to which the movement is transferred may reduce the working efficiency of the lock. There is a need for the handle-operated lock assemblies that will meet the increasing demand for hygiene in recent years.

The present invention relates to a handle lock assembly (100) for a cabinet door. The proposed handle lock assembly (100) comprises a main body (20) having a handle housing (15) extending along a longitudinal axis (X) of the handle lock assembly (100); a handle (10) provided within the handle housing (15) and adapted to move between an unlocked position in which the handle (10) is lifted from the handle housing (15) and a locked position in which the handle (10) is substantially within the handle housing (15); a lock plug (40) provided at a lock plug housing (12) of the handle (10), having a spring-biased lock cam (42) adapted to lock the handle (10) within the handle housing (15) in the locked position. Said handle lock assembly (100) comprises at least one pivotable mounted handle wheel (35) being rotatable within the handle housing (15) when the handle (10) is lifted; at least one rack gear (31) and at least one pinion gear (38) in communication with the handle wheel (35) so as to convert a rotational movement from the handle wheel (35) to a linear movement wherein the pinion gear (38) is attached to a transmission bar (37), and a base plate (30) attached to the main body (20) for substantially covering an open bottom end (25) of the main body (20). With this arrangement, the handle lock assembly (100) is almost fully closed and is arranged to be resistant to external factors. One of the greatest advantages of the invention is that the handle lock assembly (100) is completely closed in order to impart a sealing feature. The base plate (30) forms the base of the handle lock assembly (100) and closes the bottom of the handle lock assembly (100). The handle lock assembly (100) is specially produced from material that does not accumulate dirt and bacteria in particular to meet specified hygiene standards.

[0013] Referring to Fig. 1, the base plate (30) has an at least partly circumferentially arranged and outwardly protruded bottom sealing member (39). Accordingly, the bottom sealing member (39) extends completely circumferentially to cover the lateral sides of the base plate (30). The bottom sealing member (39) is adapted to be in contact with a planar surface of the cabinet door. Thus, when the handle lock assembly (100) is attached to the cabinet, the bottom sealing member (39) is pressed against the planar surface of the cabinet door and the sealing member (39) is squeezed thereby obtaining fluid-tightness thereof. In a possible embodiment, the bottom sealing member (39) can be an overmolded gasket and extends radially outwardly beyond the lower surface of the base plate (30). The base plate (30) is a separate part and is attached to the main body (20) with a plurality of connection members.

[0014] The present invention also proposes an improved gear system for the handle lock assembly (100) which offers an easier opening and closing and requires less contact. According to Fig. 1 and 9, the rack gear (31) has at least one upper tooth set (32) in mechanical communication with the handle wheel (35) and at least one inner tooth set (34) in mechanical communication with the pinion gear (38). Referring to Fig. 9, the upper tooth set (32) has a plurality of teeth, preferably 3 teeth and the inner tooth set (34) has a plurality of teeth, preferably 5 or 6 teeth. The numbers and the shapes of the teeth can vary with respect to the handle wheel (35) and the pinion gear (38). The inner tooth set (34) is provided at an inner lateral surface of the rack opening (33) as can be seen in Fig. 9. The location of the inner tooth set (34) in the rack opening (33) can also vary.

[0015] Referring to Fig. 1, the handle lock assembly (100) has two handle wheels (35) in mechanical communication with corresponding upper tooth sets (32) to move the rack gear (31) with respect to the longitudinal axis (X) of the handle lock assembly (100). The handle wheels (35) can be formed as a quarter-shaped gear wheel spaced apart from each other.

[0016] Referring to Fig. 4, the handle lock assembly (100) comprises a gear cover (21) provided within the main body (20) for covering the rack gear (31) and the pinion gear (38). Accordingly, the handle lock assembly (100) further comprises a support member (22) provided at the handle (10) and is suitable for compression in such a way that the support member (22) contacts the gear cover (21) when the handle lock assembly (100) is in the closed position. Fig. 5 shows the position of the pressed support member (22) against the gear cover (21). The support member (22) has a hollow cylindrical shape and is made from an elastic material. The gear cover (21) can have U-shaped cross-section and two guiding portions (24) for guiding the gear cover (21) within the main body (20). The main body (20) has corresponding holes for receiving guiding portions (24) in the form of a cylinder.

[0017] Referring to Fig. 7a, a rotation gear (53) is attached to the transmission bar (37) for retracting or extending a first longitudinal rod (51) and a second longitudinal rod (52) along the longitudinal axis (X) of the handle lock assembly (100). The first longitudinal rod (51) and the second longitudinal rod (52) have a plurality of engagement slots (54) for engaging gear teeth of the rotation gear (53). The engagement slot (54) is, preferably, in the form of a square-shaped hole. When the transmission is rotated the rotation gear (53) also rotates and moves the first longitudinal rod (51) and the second longitudinal rod (52) along the longitudinal axis (X). The handle lock assembly (100) comprises two matchable bottom male cover (50a) and a bottom female cover (50b) in which the first longitudinal rod (51) and the second longitudinal rod (52) are guided. The rotation gear (53) is also guided in the bottom male cover (50a).

[0018] Referring to Fig. 4, the handle lock assembly (100) comprises a joint member (23) attached to the base plate (30) in which two handle wheels (35) are pivotably coupled and an attachment portion (13) of the handle (10) is attached via a connection member (36) (i.e., a pin). The joint member (23) has preferably an attachment base for attaching the base plate (30) by at least one connection member (i.e., screw) and has a U-shaped connection portion in which two handle wheels (35) are guided.

[0019] The handle (10) has a planar upper surface on which the lock plug housing (12) is formed for receiving a corresponding lock plug (40). The lock plug housing (12) has an outer casing (14) in which the lock plug (40) is guided. This outer casing (14) has an opening through which the spring-biased lock cam (42) can extend. The attachment portion (13) of the handle (10) has a through hole in which the connection member (36) is fitted. When the handle lock assembly (100) is in the closed position, the upper surface of the main body (20) and the handle (10) is brought to the same height level which also enhances the impermeability of the handle lock assembly (100).

[0020] In a preferable embodiment, the handle lock assembly (100) further comprises a main body sealing member (11) for covering the upper circumferential end of the handle housing (15). Said main body sealing member (11) is an overmolded gasket and protrudes outwardly from the handle housing (15) wherein the main body sealing member (11) is arranged to be pressed by the handle (10) when the handle lock assembly (100) is in the closed position. In another possible embodiment of the invention, the handle lock assembly (100) comprises a circumferentially arranged and outwardly protruded handle sealing member (not shown) for covering the lateral periphery of the handle housing (15) and is arranged to be pressed against the handle housing (15) when the handle lock assembly (100) is in the closed position. The handle sealing member can be similarly shaped as the bottom sealing member (39). Thus, when the handle (10) is released from the handle housing (15), the pressed handle sealing member and/or main body sealing member (11) allows the handle (10) to be partially lifted upwards, afterwards, the user can easily hold and lift the handle (10). Such main body sealing member (11) can be made of a thermoplastic elastomer. In a possible embodiment, the main body sealing member (11) may be made of a rubber material.

[0021] Referring to Fig. 1, the lock plug (40) is arranged to be rotated by a suitable handle key. When the handle key (60) is firstly engaged and then rotated, the spring-biased lock cam (42) is retracted and the handle (10) is released from the handle housing (15). The lock cam (42) can have a rectangular shape with an inclined end portion for engaging corresponding housing in the main body (20). One end of the lock cam (42) is under the effect of the spring (43) for keeping the lock plug (40) in the closed position. In a possible embodiment, the lock plug (40) may be of any type of suitable parts of a lock cylinder available in the market. For example, a radial pin cylinder in which pins supported by respective springs are radially arranged may be preferred. Such cylinders typically require tubular keys to operate the cylinder.

[0022] In a possible usage of the handle lock assembly (100), the user puts the handle key (60) on an engagement protrusion (41) of the lock plug (40) as shown in Fig. 5a. The handle key (60) has a preferably corresponding hole which is shaped and dimensioned with respect to the engagement protrusion (41) of the lock plug (40). When the lock plug (40) is rotated, the lock cam (42) is retracted by compressing the spring (43) therein. This action transfers the pressure on the handle sealing member and/or main body sealing member (11) to the handle (10) and throws the handle (10) slightly upwards.

[0023] Thus, by holding the handle (10) easily, the handle (10) is rotated around the joint member (23) in the upward direction. This movement creates a rotation movement on the joint member (23) and is transferred to the improved rack-pinion system which creates a linear motion on the first longitudinal rod (51) and the second longitudinal rod (52). The skilled person in the art can replace another suitable means instead of such rods.

[0024] 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 boxes or cabinet covers.
