A Lock Device with Lockup Mechanism

Technical field

[1] The invention relates to a lock device, particularly a lock device with lockup mechanism.

Background

[2] A lock plate with inverse locking functionality is disclosed in a utility model patent CN 201320496122(Dl).

[3] According to D1, the lock plate includes the main body of lock plate 1, on which a lock head 2 and a keyhole 11 are provided. The lock head 2 comprises a flexible dial 4 which goes through the keyhole 11 and is driven by key.

[4] The main body of lock plate 1 is also provided with a coupler 5 and a rotary knob 7, the coupler 5 rotates along with the flexible dial 4 and the rotary knob 7 drives coupler 5 to rotate toward one single direction.

[5] This utility model patent presents a simple lock structure and the function of a reverse lock can be achieved by rotary knob 7 without any key.

[6] However, a handle is still needed in the main body of lock plate 1. Due to limited space of the main body of lock plate 1, the distance between the handle and the rotary knob 7 tends to be small.

[7] The hand can easily collide with handle while rotary knob 7 is turned, which causes inconveniences in operation and poses a safety threat.

Details of the invention

[8] To tackle the defects in existing design, the design described in the patent claim aims to optimize the structure of lockup mechanism and propose a new layout of the handle and the rotary knob to avoid the inconvenience and risk. Besides, the invention also suggests an improved structure to change direction of the lockup rotation of square shaft.

[9] In light of two purposes listed previously, this invention may provide a lock device with lockup mechanism that comprises a lock plate and a square shaft which is located in the inner side of the lock plate and is used for driving the lock tongue. A top opening is added to the lock plate. A sliding button is utilized to drive square shaft. The sliding button includes a button head and a sliding leg extending from button head. The sliding leg slides through top opening into the inner side of the lock plate and eventually connects with the square shaft in a transmission way. The button head is exposed beyond the lock plate.

[10] The inner side of lock plate refers to the surface facing toward door after the lock plate is installed. Consequently, the opposite surface is considered to be the outer side. Since the

lock plate is a three-dimensional part with at least three surfaces, for the purpose of clarity,

the parallel surface of lock plate with the door after installation is defined as the front surface. With the front surface as reference, the two surfaces located horizontal symmetrically along

the front surface are defined as the left side and the right side. Surfaces located vertical symmetrically along the front surface are defined as top reference surfaces.

[11] As mentioned previously, a top opening locates in the lock plate, which explains the location of the top opening. To be exact, the top opening locates on the top references

surfaces. Therefore, no opening is entailed in front surface of the lock plate to allow the sliding leg to enter.

[12] The square shaft serves as the driver for movement of the lock tongue. In detail, when

the square shaft rotates forward, the lock tongue will be pushed into the matching slot installed in the door frame, which is called the lockup. Oppositely, when the square shaft

rotates reversely, the lock tongue will move toward an opposite direction, and therefore be pushed out of the matching slot installed in the door frame, which indicates the removal of

thelockup.

[13] The button head will be exposed beyond lock plate. The layout of the button head

ensures that the button head is not shielded by any side of the lock plate. The easy access of the button head allows a quick and convenient operation of the button head for operators.

[14] After comparison, this invention may present several advantages. Firstly, with the top

opening placed in top reference surfaces of the lock plate, holes needed to be drilled in the front surface of the lock plate can be minimized. Reducing the number of drilling holes can

improve the appearance of the whole lock plate and leaves an impression of concision.

[15] Secondly, the location of the top opening is designed to be the end surface of the lock

plate to maximize the distance between sliding button and handle installed in the lock plate. The sliding button no longer takes the old approach of rotation, leading to a smaller occupied space to operate. Consequently, the risk of a hand bumping into the handle during the operation can be reduced significantly.

[16] Thirdly, the sliding button moves within the top opening. During the operation, the

sliding of the sliding button head can be maintained beyond the range of the lock plate, eliminating any collision avoidance hole or slot in the lock plate for the sliding button head.

As a result, the structure of lock plate is further simplified and the overall appearance is

improved as well.

[17] An optional design to further improve the lock device is to raise the front surface of

button head higher than that of the lock plate. The benefit of such design is to form a step between button head and lock plate. Operators can follow the lead of the step and push the

button head directly. Once again, an easier access is provided,

[18] An optional design to further improve the lock device is to maintain a same horizontal

width between the button head and the lock plate. Viewed from the front side, the button head is transited smoothly to the lock plate to present a concise appearance.

[19] An optional design to further improve the lock device is to add a rotation disk to the

inner side of lock plate. The square shaft is fixed in the rotation disk. The rotation disk is equipped with convex columns which connect to the sliding leg in a transmission way.

Consequently, when the sliding leg moves, the rotation of the rotation disk is triggered via convex columns and subsequently the square shaft is driven indirectly.

[20] An optional design to further improve the lock device is to add one pair of horizontally symmetrical extension arms to the rotation disk. The convex columns can be adjusted to link

with one of extension arms. The sliding leg contains one pair of horizontally symmetrical connection hooks which allow the convex column to enter and connect. The rotation direction

of square shaft can be changed by adjusting the connection of convex columns. The lock

device can be locked or unlocked via the rotation direction of square shaft.

[21] Due to the highlights and advantages, this invention can apply to various types of lock

devices with lockup mechanism.

Detailed description of embodiments

[28] As the figures demonstrated, the lock device with lockup mechanism comprises a lock plate 1 and a square shaft 5 which is located in the inner side of lock plate 1 and is used for

driving lock tongue 71. The characteristic lies in a top opening 11added to the lock plate 1. A sliding button 2 is utilized to drive square shaft 5. Sliding button 2 includes a button head 21

and a sliding leg 24 extending from button head 21. Sliding leg 24 slides through top opening

11 into the inner side of the lock plate and eventually connects with square shaft 5 in a transmission way. Button head 21 is exposed beyond the lock plate 1.

[29] With the figures, further instructions are provided regarding the lock device with lockup mechanism described in the invention.

[30] Figure 1 to figure 5 demonstrates that lock plate 1 includes a front surface 12, and two end surfaces (left surface 13 and right surface 14) along front surface 12, and lower surface

below front surface 12. Front surface 12, left surface 13 and right surface 14 and lower surface 15 form a cavity inside lock plate 1. Installation hole 16 for a handle locates on front

surface 12; handle 3 goes through a washer 30 and is installed in installation hole 16. A pair

of reversers (8, 80) locates in the cavity of lock plate 1. Reversers (8, 80) restrict the placement of the handle 3. Rotation disk 4 locates above reversers (8, 80). Rotation disk 4 includes one

pair of horizontal symmetrically extending arms (41, 42) with installation holes (410,420). Convex column 40 can be snapped into installation hole 41, which can be removed as well.

Square shaft 5 which is fixed in rotation disk 4 locates between a pair of installation holes (410,420).

[31] As demonstrated in Figure 5, the top of lock plate 1 is open, which means no wall is fabricated on the top reference surface to form a top opening 11. Sliding button 2 locates in

top opening 11. Sliding button 2 includes a button head 21and a sliding leg 24 extending from button head 21. Sliding leg 24 slides through top opening 11 into the inner side of the lock plate and eventually connects with square shaft 5 in a transmission way. Button head 21 is exposed beyond lock plate 1. Sliding leg 24 includes a pair of horizontal symmetrically supporting arms (22, 23) and two hooks (220,230) connected to ends of two supporting arms (22, 23). Convex column 40 enters into hook 230. A pressure sensor 6 locates in the inner side of lock plate 1. Pressure sensor 6 is bolted in lock plate 1 and serves as a sliding guide together with lock plate 1for support arms (22, 23).

[32] Figure 6 demonstrates the structure of a lock main body 7 which matches with the

lockup mechanism. The main body 7 includes a movable locktongue 71and a connection hole for square shaft. After installation, square shaft 5 reaches into connection hole 70. In order

to lock the lock device, operators can hold the button head 21to push sliding button 2 along F direction. Consequently, connection hook 230 is pulled upward. In this way, by convex

column 40 connection hook 230 drags rotation disk 4 and subsequently square shaft 5 locating in rotation disk 4 is also pulled and rotates anticlockwise. During the rotation of

square shaft 5, the transmission device (not shown in the figure) in main body 7 pushes lock

tongue 71 into the matching hole 71 in the door frame. Oppositely, when button head 21is pushed along the reversed direction of F, via convex column 40, connection hook 230 drives

rotation disk 4 and square shaft 5 to rotate clockwise. During the rotation of square shaft 5, the transmission device (not shown in the figure) in main body 7 drives lock tongue 71 out of

the matching hole 71in the door frame. In need of changing the rotation direction of square shaft 5 for lockup, operators simply need to install convex column 40 into installation hole

420.

[33] After comparison, the invention may present several advantages. Firstly, with top

opening 11 placed in top reference surfaces of lock plate 1, the number of holes to be drilled

in the front surface of lock plate 1 can be minimized. Reducing the number of the drilling holes can improve the appearance of whole lock plate 1 and leaves an impression of concision.

[34] Secondly, the location of top opening 11 is designed to be to the end surface of lock plate 1 to maximize the distance between sliding button 2 and handle 3 installed in lock plate

1. Sliding button 2 no longer takes the old approach of rotation, leading to smaller occupied space to operate. Consequently, the risk of hand bumping into handle 3 during the operation

can be reduced significantly. Third, sliding button 2 moves within top opening 11. During the operation, the sliding of sliding button head 21 can be maintained beyond the range of lock plate 1, eliminating any collision avoidance hole or slot in lock plate 1for sliding button head 21. As a result, the structure of lock plate 1 is further simplified and the overall appearance is improved as well.

[35] As demonstrated in figure 3, an optional design to further improve the lock device is

to raise front surface 210 of button head 21 higher than front surface 10 of lock plate 1. The

benefit of such design is to form a step between button head 21 and lock plate 1. Operators can follow the lead of the step and push button head 21 directly. Once again, an easier access

is provided,

[36] As demonstrated in figure 1, an optional design to further improve the lock device is

to maintain the horizontal width W2 of button head 21 the same as horizontal width W1 of lock plate 1. Viewed from the front side, button head 21is transited smoothly to lock plate 1

to present a concise appearance.
