Abstract

An improved structure of a buckle device includes a housing and an actuating body mounted on the housing, a linkage frame, and a sliding body. The actuating body has a free end and a pivot end pivotally connected to the housing, so that the actuating body can move back and forth and rotate (or swing); the free end of the actuating body is provided with two cantilevers and an opening area between the cantilevers, and the opening area is used to set an operating part and an elastic member. In addition, the linkage frame has a first end pivotally connected to the middle area of the actuating body (or between the free end and the pivot end, and away from the free end); the linkage frame has a second end assembled to the housing. Furthermore, when a person pulls (and pushes) the operating part to move, the auxiliary actuator moves from a closed position toward an open position, driving the linkage frame and the sliding body to move, thereby improving the opening angle of the structure and providing a smaller area for the person to hold (or operate), thus affecting the smoothness (or convenience) of the operation.

Description

Improved structure of buckle device

The present invention relates to an improved structure of a buckle device; in particular, it refers to a technique of arranging an operating part assembly elastic member on an actuating body and pivoting a linkage frame on a housing and a middle area of the actuating body to improve the smoothness (or convenience) of the operation of the known structure.

It is a learned skill to install a locking device or a similar device on the cover structure of a computer/electronic equipment, server chassis, etc. to allow personnel to open/close the computer/electronic equipment or control the cover structure to lock and close the chassis body to prevent the internal components or parts of the chassis from being exposed, or to operate the cover structure to open so that personnel can configure, repair, etc. the components inside the chassis.

For example, US 11297730 B1 "TOOL FREE REMOVABLE CHASSIS COVER", US 7201407 B2 "SLIDING PANEL LATCH", US 6145352 "SLAM LATCH WITH OPPOSING SLIDES", CN 110388148 A "Latch device", CN 115961844 A "Buckle device" (i.e., Taiwan No. 110138018 "Buckle device"), CN 219754305 U "Latch", Taiwan No. 112139241 "Buckle device improved structure" patents, etc., provide typical embodiments.

This type of latching device usually includes a housing, an actuating handle and a sliding plate; a push button is provided at one end of the housing. The actuating handle has a pivoting end that cooperates with a spring and is pivoted to the other end of the housing; the inner side of the other end of the actuating handle is pivoted to a connecting rod, and a protrusion is provided at the other end of the actuating handle to allow the protrusion to be embedded in the push button to form a locked state. When a person operates the push button to release the protrusion, the spring pushes the actuating handle to open, driving the sliding plate to move and the connecting rod to lift up the actuating handle. For example, the above-mentioned CN 110388148 A "Latching Device" and CN 219754305 U "Latching" patents, etc., disclose specific embodiments.

One of the issues concerning the structure and operation application of the combination type of the known latch device is that the structure of the actuating handle and the push button is configured at the same time on the inherent length or specification of the housing, that is, the length of the actuating handle must be shortened, which also relatively affects the convenience of operation of the actuating handle.

In order to improve the above situation, the old law has also disclosed a latch device including a housing, an actuating handle and a sliding plate (for example, Taiwan Patent No. 110138018 "Lock Device" and No. 112139241 "Lock Device Improved Structure"). The embodiment includes a housing and an actuating body mounted on the housing, a linkage frame, and a sliding body. The actuating body has a free end and a pivot end of the housing pivoted with an elastic device, so that the actuating body can form a reciprocating motion; the free end of the actuating body is provided with an opening area for setting a movable operating part. In addition, the linkage frame has a first end pivoted in the inner area of the free end (or operating part) of the actuating body and a second end connected to the sliding body; when a person presses the operating part (swings), the actuating body is allowed to move from a closed position to an open position, thereby driving the linkage frame and the sliding body to move.

The embodiment uses the structure of the operating part directly combined with the actuator, so that the length of the actuator can be increased as much as possible, making its length greater than the length of the learned structure and the operation structure and the actuator, the linkage frame, and the sliding body can move smoothly; it improves the situation where the learned structure is limited in length/specifications due to the configuration space/volume, affecting the convenience of operation.

One of the problems in the combination of the above-mentioned embodiments in terms of structure and operation application is that the structure in which the first end of the linkage frame is pivotally connected to the inner area of the top of the actuating body prevents the operator from operating the actuating body to move in the opening direction. In other words, when the operator operates the actuating body to move in the opening direction, the linkage frame (and the first end of the linkage frame) located in the inner area of the actuating body is also driven to move, which significantly reduces the area (or space) for the operator to hold (or operate) the actuating body, which relatively affects the smoothness or convenience of the operation.

Another problem with the combination of the above-mentioned embodiments in terms of structure and operational application is that the first end of the linkage frame is pivotally connected to the inner area of the top of the actuator, which also reduces the maximum opening angle or opening angle of the actuator, which is not what we expect.

Typically, these references show the techniques of structural assembly design and application of a latch device or a similar locking mechanism. If the structural assembly type of the latch (or locking mechanism) and the actuating handle is redesigned and considered to make its structure different from that of the user, its usage form can be changed and different from the old method; in essence, its application effect will also be increased.

We find that an ideal latch or buckle device must be able to overcome or improve the issues discussed above and should include or have the following design considerations:

1. Under the condition that the structure (or housing) has the same length or specification, the length of the actuating handle is made longer than the length of the known structure; therefore, it is necessary to have a structural type in which the pressing operation structure can be directly combined with the actuating handle (or actuating body), and the pressing operation structure and the actuating handle (or actuating body) can still achieve the effect of smooth movement without affecting or shortening the length of the actuating handle.

2. Consider providing an improved structure, changing the known structure of the linkage frame pivoted to the inner area of the top of the actuator to reduce the area (or space) for the operator to hold (or operate) the actuator. Or further consider that the improved structure can increase the maximum opening angle or opening angle of the actuator.

These topics are not taught or specifically disclosed in the above-mentioned references.

Therefore, the main purpose of the present invention is to provide an improved structure of a buckle device, including a housing and an actuating body mounted on the housing, a linkage frame, and a sliding body. The actuating body has a free end and a pivot end pivotally connected to the housing, so that the actuating body can form a reciprocating and rotating (or swinging) motion function; the free end of the actuating body is provided with two cantilevers and an opening area between the cantilevers, and the opening area is used to set an operating part and an elastic member. In addition, the linkage frame has a first end pivotally connected to the middle area of the actuating body (or a position adjacent to the lower area, or between the free end and the pivot end, and the area away from the free end); the linkage frame has a second end assembled to the housing. Furthermore, when a person pulls (and pushes) the operating part to move, the auxiliary actuator moves from a closed position toward an open position, driving the linkage frame and the sliding body to move, thereby improving the opening angle of the structure and providing a smaller area for the person to hold (or operate), thus affecting the smoothness (or convenience) of the operation.

According to the improved structure of the buckle device of the present invention, the pivot end of the actuating body is provided with two auxiliary cantilevers and an auxiliary opening area between the auxiliary cantilevers, and the auxiliary opening area is used to accommodate or set the linkage frame. In addition, the auxiliary opening area is provided with an auxiliary pin hole, which cooperates with the auxiliary shaft pin to pivotally connect the first end of the linkage frame, so that the linkage frame is formed into a shape that can move (or swing) with the actuating body; and, the (maximum) opening angle (or opening angle) of the actuating body is achieved to be greater than the (maximum) opening angle of the known structure.

Please refer to Figures 1, 2 and 3. The improved structure of the buckle device of the present invention includes a housing, an actuator, a linkage frame and a sliding body, which are respectively represented by reference numbers 10, 20, 30 and 40. The housing 10 has a bottom wall 11, two side walls 12 extending in a direction parallel to the axis of the housing 10, a main end wall 13 and a secondary end wall 14 connected to the side walls 12 and perpendicular to the axis of the housing 10, and together define an open chamber 15 of the housing 10 to accommodate the actuator 20, the linkage frame 30 and the sliding body 40.

In the following descriptions, when upper, above, lower, below, right, left, side, etc. are mentioned, the directions shown in the figures are used as reference directions.

The figure shows that the side wall 12 of the housing 10 is provided with an elongated hole 16, the main end wall 13 is formed with a notch 18 structure, and the secondary end wall 14 is provided with a secondary positioning portion 19 having a notch structure. In addition, the inner side of the side wall 12 of the housing 10 is provided with a flange structure 12a, which can assist the standard sliding body 40 to form a smooth sliding movement in the chamber 15 of the housing 10.

In the embodiment adopted, the actuating body 20 is a plate structure, defining an axial direction X, a free end 21 and a pivot end 22 that cooperates with the elastic device 50 to pivot the housing 10, so that the actuating body 20 can form a reciprocating (moving and/or swinging) motion.

Specifically, the free end 21 of the actuator 20 is provided with two (parallel) protruding cantilevers 25 and an opening area 26 between the two cantilevers 25. Also, the inner edge of the cantilever 25 is parallel to the axial direction X of the actuator 20 and is provided with a track 95; the free end 21 or the tail of the cantilever 25 is provided with a pin hole 27, corresponding to the type of a pivot pin 77.

2 and 3 reveal that the pivot end 22 of the actuating body 20 is provided with two auxiliary cantilevers 25a and an auxiliary opening area 26a located between the auxiliary cantilevers 25a, wherein the auxiliary opening area 26a is used to accommodate or set the linkage frame 30. Also, the pivot end 22 of the actuating body 20 is provided with an axle connection portion 23.

In the embodiment adopted, the secondary opening area 26a is adjacent to the shaft connection portion 23; the area of the actuating body 20 far from the free end 21 (or the secondary cantilever 25a (or the secondary opening area 26a) is adjacent to the middle area of the actuating body 20 (or the position adjacent to the lower area (in the figure)), and a secondary pin hole 27a is provided, which cooperates with the secondary shaft pin 75 to pivotally connect the first end 31 of the connecting frame 30, so that the connecting frame 30 is formed into a shape that can move (or swing) with the actuating body 20; and, the (maximum) opening angle (or opening angle) of the actuating body 20 is achieved to be greater than the (maximum) opening angle of the known structure.

The figure also shows the area of the actuating body 20 adjacent to the pivot portion 23, which is provided with a (oblique) pressing portion 24 (or oblique edge) for the elastic device 50 to press against and assist the actuating body 20 in moving.

Specifically, the elastic device 50 is in the form of a torsion spring, and has a ring portion 53, a first section 51 connected to the ring portion 53, a second section 52, and an extension section 54 (vertically) connected to the second section 52. Furthermore, the shaft connection portion 23 of the actuator 20 is combined with a shaft column 73, and the shaft column 73 is inserted into the ring portion 53 of the elastic device 50 and the elongated hole 16 formed on the side wall 12 of the housing 10; the first section 51 of the elastic device 50 abuts against the pressing portion 24 of the actuator 20, and the second section 52 (and/or the extension section 54) abuts against the sliding body 40, so that the actuator 20 takes the shaft column 73 (and/or the shaft connection portion 23) as the center of motion, and allows the actuator 20 (or the pivot end 22) to move along the elongated hole 16, forming a reciprocating motion (and/or swinging) pattern.

In the embodiment, the actuating body 20 is provided with an assembly portion 96 in the area inside the opening area 26 (or away from the tail of the cantilever 25) for assembling (or positioning) an elastic member 55; the assembly portion 96 can be formed into a convex pile or concave hole structure. In addition, the opening area 26 is used to set the operating portion 80 and an elastic member 55 that assists the operating portion 80 to generate reciprocating motion in the axial direction X of the actuating body 20.

Specifically, the operating part 80 includes a base 83 for operation, a main area 81 and a secondary area 82 located at both ends of the base 83; the base 83 is a concave structure (and/or grooves 87 connected to the concave structure are formed on both sides of the base 83) to facilitate the operator to pull (or push) the operating part 80 to move. The bottom area of the operating part 80 (adjacent to the positioning part 84) is provided with a secondary groove 88, which cooperates with the shaft pin 77 to regulate the moving distance or range of the operating part 80. Corresponding to the track 95 of the cantilever 25, a secondary track 85 is provided on the side of the operating part 80. Combined with the above-mentioned track 95, the auxiliary operating part 80 can move back and forth (linearly) more smoothly along the axial direction X, and ensure that the operating part 80 can be located at the correct position of the opening area 26 (or between the two cantilevers 25) during the movement of the actuating body 20.

In addition, the operating portion 80 or the main area 81 is provided with a secondary assembly portion 86 (a recessed structure or a convex structure) for assembling or accommodating the elastic member 55; the secondary area 82 is provided with a positioning portion 84 in a hook-shaped structure; when the actuating body 20 is in the closed position (or the actuating body 20 is closed in the housing 10), the positioning portion 84 is allowed to assemble (or lock) with the secondary positioning portion 19, so that the actuating body 20 (or the operating portion 80) is embedded or buckled on the housing 10 to form a fixed shape.

In a feasible embodiment, the elastic member 55 is selected to be in the form of a coil spring (or other elastic structure), having a first area 56 positioned (or assembled) on the assembly portion 96 and a second area 58 accommodated (or pressed) in the auxiliary assembly portion 86, so as to achieve the function of enabling the operating portion 80 to generate reciprocating motion and keeping the positioning portion 84 and the auxiliary positioning portion 19 locked.

The figure shows that the linkage frame 30 is T-shaped and defines a first end 31 and a second end 32; the first end 31 is provided with a pin hole 37, which is pivotally connected to the above-mentioned secondary shaft pin 75, so that the first end 31 of the linkage frame 30 forms a pivotally connected secondary pin hole 27a of the actuator 20 in a freely rotatable (or swingable) manner.

In the embodiment, the second end 32 of the linkage 30 is provided with a secondary shaft connection 33 for pivoting a shaft 70, so that the second end 32 of the linkage 30 can move or rotate freely. In addition, the second end 32 of the linkage 30 (or the area adjacent to the secondary shaft connection 33) is provided with a recess 34 for accommodating the ring 53 of the elastic device 50; the shaft 70 is combined with the secondary shaft connection 33 of the linkage 30 and pivoted with the shaft hole 17 of the housing 10.

The figure depicts a sliding body 40 in a plate structure, which is mounted on the housing 10 (or the chamber 15) to form a freely movable form. The sliding body 40 is defined with a main end 43 and a secondary end 44; between the main end 43 and the secondary end 44, a combination part 41 in a convex plate structure and an axial hole 42 formed on the combination part 41 are provided.

Therefore, the shaft 73 is combined with the shaft connection portion 23 of the actuator 20, the shaft hole 42 of the sliding body 40 and the ring portion 53 of the elastic device 50; and the shaft 73 (both ends) are pivotally connected to the long hole 16 of the housing 10. When a person operates (or pulls) the operating portion 80 to move along the axial direction X, the actuator 20 is allowed to move from a closed position to an open position, and the linkage 30 is driven to move, so that the shaft 73 moves along the long hole 16, drives the actuator 20 (or the pivot end 22) to move and rotate, and causes the sliding body 40 to generate (move) movement.

The closed position refers to the position where the actuator 20 and the linkage frame 30 are retracted in the housing 10 (or the chamber 15); the open position refers to the position where the actuator 20 (or the free end 21) and the linkage frame 30 (or the first end 31) move away from the housing 10.

It can be understood that the movement range (or angle) of the actuator 20 to open or close the housing 10 can be controlled by the distance between the axle connection portion 23 of the actuator 20 and the secondary pin hole 27a, the distance between the secondary axle connection portion 33 of the linkage 30 and the pin hole 37, and the movement distance of the sliding body 40 (and/or the length of the elongated hole 16, the movement distance of the shaft 73).

FIG4 shows a state in which the positioning portion 84 of the operating portion 80 is coupled or snapped onto the auxiliary positioning portion 19 of the housing 10, while the actuating body 20, the linkage frame 30 and the sliding body 40 are kept closed in the housing 10 (or the chamber 15), and the elastic device 50 (pressed by the pressing portion 24 of the actuating body 20) is in a state of accumulating energy.

Please refer to FIG5 , when a person (finger) pulls the operating part 80 toward the left side in the figure through the base 83 to move along the axial direction X, the operating part 80 pushes the elastic member 55 to accumulate energy, and the positioning part 84 leaves the auxiliary positioning part 19 of the housing 10. Therefore, the elastic member 50 releases the accumulated energy, pushing the actuating body 20 to move and rotate toward the open position, and driving the linkage frame 30 and the sliding body 40 to move; for example, the situation depicted in FIG6 .

The figure also shows that the actuating body 20 (or the pivot end 22) cooperates with the shaft 73, moves along the elongated hole 16, and generates a rotational (or swinging) motion, so that the sliding body 40 moves between the main end wall 13 (or its notch 18) and the secondary end wall 14 of the housing 10.

In a feasible embodiment, when the actuating body 20 is closed in the housing 10, a portion of the main end 43 of the sliding body 40 protrudes from the notch 18 of the main end wall 13 of the housing 10. When the actuating body 20 is in the open position, the secondary end 44 of the sliding body 40 protrudes from the secondary end wall 14 of the housing 10.

It is understood that the structure of the auxiliary suspension arm 25a and the auxiliary opening area 26a of the actuating body 20 combined with (or accommodating) the linkage frame 30 makes the movement of the linkage frame 30 (or the linkage frame 30 moves with the actuating body 20 from behind the actuating body 20) not hinder the operation or holding area of the actuating body 20 (or the inner area of the actuating body 20), and relatively provides a larger operation space (or a holding space for a person's hand) for the actuating body 20. In addition, the structure of the first end 31 of the linkage frame 30 pivotally connected to the middle area (or near the lower area) of the actuating body 20 also provides the actuating body 20 with a larger opening angle or movement angle than the conventional structure.

Please refer to FIG. 7, FIG. 8 and FIG. 9. In a derivative embodiment, the pivot end 22 of the actuating body 20 is pivoted to the housing 10 with the elastic device 50, so that the actuating body 20 can form a reciprocating (swinging) motion (or simple harmonic motion).

Specifically, the pivot end 22 (or the pivot portion 23) of the actuator 20 is provided with a secondary recess 24a to assist in assembling (or positioning) the elastic device 50, and the actuator 20 is also provided with a recess 24b adjacent to the pivot portion 23; and the shaft 70 is assembled on the pivot portion 23, the ring portion 53 of the elastic device 50 and the shaft hole 17 on the side wall 12 of the housing 10; the first section 51 of the elastic device 50 abuts against the bottom wall 11 of the housing 10, and the second section 52 abuts against the actuator 20 (or the pivot portion 23), so that the actuator 20 takes the shaft 70 (and/or the shaft hole 17, the pivot portion 23) as the rotation center, forming a reciprocating (or swinging) type.

The figure shows that the region between the free end 21 and the pivot end 22 of the actuator 20 (or the region far from the shaft connection portion 23, or the region far from the free end 21) is provided with a secondary pin hole 27a, which cooperates with the secondary pin 75 to pivotally connect the first end 31 of the linkage frame 30, so that the linkage frame 30 is formed into a shape that can move (or swing) with the actuator 20. In addition, the side (middle region) of the actuator 20, adjacent to the secondary pin hole 27a, is formed with a (long) groove 27b for accommodating or allowing the side of the linkage frame 30 to enter.

In the embodiment adopted, the pin hole 37 of the first end 31 of the linkage 30 is pivoted to the secondary shaft pin 75. Also, the secondary shaft connection portion 33 of the second end 32 of the linkage 30 is pivoted to the shaft column 73, so that the second end 32 of the linkage 30 forms a freely movable or rotatable form; when the actuator 20 is in the closed position, the secondary shaft connection portion 33 can be accommodated in the recess 24b. Also, the shaft column 73 is pivoted to the assembly portion 41 (or shaft hole 42) of the sliding body 40; and, the shaft column 73 (both ends) is pivoted to the elongated hole 16 of the housing 10.

When a person operates (or pulls) the operating portion 80 to move along the axial direction X, the actuator 20 is allowed to move from the closed position to the open position, thereby driving the linkage 30 to move, causing the shaft 73 to move along the elongated hole 16, and driving the sliding body 40 to generate movement.

It is understood that the known structure may generate a (vertical) component force toward the downward direction (closing) during the operation of the actuator 20 to open. The structural type of the intermediate area (or the area close to the pivot portion 23) of the movable actuator 20 and the first end 31 of the linkage 30 pivoted by the secondary shaft pin 75 is conducive to the actuator 20 moving (or moving, rotating) in the opening direction with the secondary shaft pin 75 as the fulcrum, thereby reducing the influence of the above-mentioned component force.

Please refer to Figures 7, 8 and 9. The free end 21 of the actuator 20 is provided with a connecting arm 25b and a secondary recessed area 25c formed on the connecting arm 25b at the tail of the cantilever 25, which is used to assist in regulating the moving distance or range of the operating part 80. The actuator 20 is provided with a recessed hole 28 and a limiting portion 29 formed on the recessed hole 28 between the free end 21 and the pivoted end 22; and the recessed hole 28 is equipped with a locking mechanism 60. The locking mechanism 60 includes a combination of a rotating body 61 accommodated in the recessed hole 28 and a locking plate 62 pivoted to the rotating body 61.

The figure depicts that the swivel 61 is formed with a secondary limiting portion 63 and a base portion 64 having a cam structure; and the lock plate 62 can be (integrally) assembled with a wing portion 66, and the wing portion 66 has a connecting portion 65 having a hole structure. Moreover, after the lock mechanism 60 is installed in the recess 28, the base portion 64 is allowed to (protrude) pivotally connect the connecting portion 65; when a person operates the swivel 61 to rotate, the limiting portion 29 of the actuator 20 blocks the secondary limiting portion 63, so as to regulate the rotation angle or rotation range of the swivel 61.

In the embodiment adopted, corresponding to the structure of the locking mechanism 60, the linkage frame 30 is provided with a locking hole 36 between the first end 31 and the second end 32 to allow the locking plate 62 (or the wing 66) to pass through. The locking hole 36 is formed by a ring convex portion 39 formed on a through hole 38.

It is understood that when the lock mechanism 60 is in the locked state, the wing 66 is locked on the locking hole 36 (or the annular protrusion 39), so that the actuator 20, the linkage frame 30 and the sliding body 40 are closed and fixed to the housing 10 (or the chamber 15). When a person rotates the rotating body 61, the locked state of the wing 66 and the locking hole 36 of the linkage frame 30 is released, and the unlocked state is formed.

Please refer to Figures 8 and 9. When a person (finger) pulls the operating part 80 toward the left in the figure through the base 83 to move along the axial direction X, the operating part 80 pushes the elastic member 55 to accumulate energy, and the positioning part 84 leaves the auxiliary positioning part 19 of the housing 10. Therefore, the elastic member 50 releases the accumulated energy, pushes the actuating body 20 to move toward the open position, and drives the linkage frame 30 to move; for example, the situation depicted in Figure 9.

The figure also shows that the actuating body 20 causes the second end 32 of the linkage 30 to drive the shaft 73 to move along the elongated hole 16 and causes the sliding body 40 to move between the main end wall 13 (or its notch 18) and the secondary end wall 14 of the housing 10.

Typically, the improved structure of this buckle device has the following advantages compared to the old method:

1. The housing 10, the actuating body 20, the linkage 30, the sliding body 40 and the related component structures have been redesigned. For example, the free end 21 of the actuating body 20 is provided with two cantilevers 25 and an opening area 26, which are equipped with an operating part 80, and the pivot end 22 of the actuating body 20 is provided with a secondary cantilever 25a and a secondary opening area 26a, which are used to assemble the linkage frame 30 so that the actuating body 20 generates movement and rotation (or swinging) motion; or the actuating body 20 is provided with a secondary recess 24a and a recess area 24b, which assist in accommodating the elastic device 50 (or the ring 53) and the secondary shaft connection part 33, and the shaft column 73, and the side of the actuating body 20 forms a groove 27b, and the opening area 26 is provided with a connecting arm 25b, a secondary recess area 25c and other parts, which are obviously different from those of the users, and also change the structure or combination relationship of the known latch device, so that its use and operation mode are different from the old method.

2. Under the condition that the structure (or housing) has the same length or specification, the length of the actuating body 20 (or the actuating handle) is made longer than that of the known structure; and, under the premise of not affecting or shortening the length of the actuating handle, the pressing operation structure (or the operating portion 80) is directly coupled to the actuating body 20, while still achieving the effect of smooth operation.

3. The structural combination of the actuating body 20 and the linkage frame 30 changes the conventional structural combination of the linkage frame pivotally connected to the inner area of the top of the actuating body and reduces the area (or space) for a person to hold (or operate) the actuating body. In particular, the structural combination of the actuating body 20 and the linkage frame 30 increases the maximum opening angle or opening angle of the actuating body 20; and the structural combination of the auxiliary opening area 26a for accommodating the linkage frame 30 can also reduce the situation where the stacking of components affects the height or space.

Therefore, the present invention provides an improved structure of an effective buckle device, whose spatial form is different from the known one and has advantages that cannot be compared with the old method. It shows considerable progress and fully meets the requirements of a new patent.
