The housing 110 is used to house other components of the latching device 100 and to mount the latching device 100 to the first article 200 (see Figure 9C). The handle 120 is pivotally provided to the housing 110 and can be operated to rotate relative to the housing 110 . The sliding member 130 is arranged on the handle 120 near the pivot end 121 and located in the housing 110 .

The sliding member 130 can slide longitudinally relative to the housing 110 and act on the second object 300 (see FIG. 9B ), so that the first object 200 and the second object 300 move relative to each other, for example, longitudinally. In this embodiment, the sliding member 130 includes a first pin 131 and a second pin 132. The first pin 131 and the second pin 132 respectively extend transversely and can move longitudinally relative to the housing 110, and the first pin 131 is is closer to the pivot end of handle 120 than second pin 132 . In other embodiments, the sliding member 130 may also be provided as an integral component, such as a plate-shaped component (not shown) that is connected between the first pin 131 and the second pin 132 . ).

In this embodiment, the sliding member 130 is used not only to drive the second object 300 but also as a rotation axis of the handle 120 , thus advantageously reducing the number of components of the latch device 100 .

Button 160 is used to maintain handle 120 in the closed position. The lock core 170 and the lock tongue 175 are used to lock or release the handle 120. The first elastic member 180 is used to spring the handle 120 from the closed position for operation. The second elastic member 190 biases the button 160 so that the button 160 tends to maintain the handle 120 in the closed position.

The specific structure of the housing 110 is described with reference to FIGS. 3A and 3B. The housing 110 includes a bottom wall 111, a side wall 112, a chute 113, an end section 113b, an opening 115, and a hook 116.

The bottom wall 111 is located vertically below the housing 110, and at least one side wall 112 is connected to a lateral side of the bottom wall 111. In this embodiment, the bottom wall 111 has side walls 112 on both lateral sides, which is beneficial to the symmetry and stability of the product. It should be understood that the housing 110 can also have only one side wall 112 and still be able to achieve the functions of the invention.

A rim may be provided around the top opening 117, and screw holes may be provided on the rim to facilitate mounting the housing 110 to the first object 200, but this is not necessary.

A chute 113 extending generally longitudinally is defined in the side wall 112 . Chute 113 is used for The sliding member 130 is guided to move longitudinally relative to the housing 110 , so the form of the slide groove 113 can be specifically set according to the form of the sliding member 130 . For example, in this embodiment, the slider 130 is configured to move along an arc, so the chute 113 includes an arcuate segment 113a that is curved toward the bottom wall 111 of the housing 110 . In other embodiments, the sliding member 130 may also be configured to move linearly, and the chute 113 accordingly assumes a linear shape.

More specifically, both longitudinal ends of the arcuate section 113 a of the chute 113 have approximately the same height, which is beneficial to fully utilizing the vertical space of the housing 110 . In this embodiment, the chute 113 further includes an end section 113b, which is connected to the end of the arcuate section 113a away from the free end 122 and extends toward the top opening 117. End section 113b facilitates retaining slider 130 in the closed position, as will be described in detail below.

A recess 111 a is provided near one longitudinal end of the bottom wall 111 of the housing 110 (ie, the end corresponding to the pivot end 121 of the handle 120 ), which is recessed vertically downward compared to other parts of the bottom wall 111 . The recessed portion 111a may generally correspond to the longitudinal position of the slide groove 113 to provide a moving space for the slider 130 .

The bottom wall 111 of the housing 110 is provided with an opening 115 , and the connecting piece 150 passes through the opening 115 and enters the housing 110 . The opening 115 may be provided at the recess 111a, that is, the opening 115 may correspond to the longitudinal position of the slide groove 113, so as to facilitate the overall compact structure of the latch device 100. The opening 115 may include a first section 115a and a second section 115b connected to each other in the longitudinal direction, and the width of the first section 115a is smaller than the width of the second section 115b in order to retain the connector 150, as will be described in detail below. More specifically, the second section 115b is closer to the free end 122 of the handle 120 than the first section 115a (ie, the left position in FIGS. 3A and 3B ).

The bottom wall 111 may also be provided with a hook portion 116, which is a portion that rises upward from the bottom wall 111 and extends longitudinally. Hook 116 cooperates with latch 175 to lock handle 120 to housing 110 (see Figure 9D).

The specific structure of the handle 120 is described with reference to FIGS. 4A and 4B. The handle 120 includes a pivot end 121 , a free end 122 , a joint portion 123 , a first pin hole 124 , a second pin hole 125 , a lock core hole 126 , and a handle protrusion 127 .

The pivot end 121 is pivotally connected to the housing 110, and the free end 122 is longitudinally opposite to the pivot end 121 and can rotate relative to the pivot end 121 about a transverse axis.

In this embodiment, a joint portion 123 is provided near the pivot end 121 for connecting to the slider 130 . The joint portion 123 is provided as an arc-shaped portion extending vertically downward. The first pin hole 124 is provided at a longitudinal position of the joint portion 123 close to the pivot end 121 and close to the vertical top surface of the handle 120 . The second pin hole 125 is disposed near the longitudinal middle of the joint portion 123 and away from the vertical top surface of the handle 120 , or in other words, the second pin hole 125 is disposed at the arcuate bottom end of the joint portion 123 . Therefore, the first pin hole 124 is closer to the pivot end 121 and closer to the top surface of the handle 120 than the second pin hole 125 . It should be understood that the shapes and positions of the joint portion 123 , the first pin hole 124 , and the second pin hole 125 correspond to the shape and position of the slider 130 , and can be changed accordingly according to the shape and position of the slider 130 . For example, when the slider 130 is configured as an integral plate-shaped component including the first pin 131 and the second pin 132 , the joint portion 123 can be configured as a plug-in slot or a connecting foot, and there is no need to provide the first pin hole 124 and the second pin hole 124 . Pin hole 125.

The lock core hole 126 is provided near the longitudinal middle of the handle 120 and vertically penetrates the handle 120 . A handle protrusion 127 is provided at the free end 122 of the handle 120 and projects longitudinally.

The specific structure of the button 160 is described with reference to FIGS. 5A and 5B.

The button 160 includes a button protruding part 161, a pressing part 162, a button shaft 163, and a second elastic member mounting part 164. The button protrusion 161 and the button shaft 163 are provided at both longitudinal ends of the button 160 . The button shaft 163 pivotally couples the button 160 to the housing 110 , and the button protrusion 161 serves to limit the rotation range of the button 160 relative to the housing 110 . The pressing part 162 is provided on the top surface of the button 160 so that the user can press the button 160 . The second elastic member mounting portion 164 is provided on the button 160 for the second elastic member 190 to be sleeved on it (see Figure 10D and Figure 11D).

More specifically, the button 160 is located near the free end 122 of the handle 120 and has an initial position in an unstressed state and a pressed position in a compressed state. When the button 160 is in the initial position, the button 160 blocks the free end 122 of the handle 120 to prevent the handle 120 from rotating relative to the housing 110 . When the button 160 is in the depressed position, the button 160 releases the free end 122 of the handle 120 to allow the handle 120 to rotate relative to the housing 110 . The operation of the engagement latch device 100 is described in detail below.

The specific structure of the first elastic member 180 is described with reference to FIG. 6 .

The first elastic member 180 is in the form of a coil spring and has a first elastic member first end 181 , a first elastic member second end 182 , and a first elastic member surrounding portion 183 . The first end 181 of the first elastic member is against the lower surface of the handle 120 , the second end 182 of the first elastic member is against the bottom surface of the housing 110 , and the first elastic member surrounding portion 183 is sleeved on the second pin 132 superior. Therefore, the first elastic member 180 biases the handle 120 toward the opening direction.

The specific structure of the second elastic member 190 is described with reference to FIG. 7 .

The second elastic member 190 is in the form of a coil spring and has a second elastic member first end 191 , a second elastic member second end 192 , and a second elastic member surrounding portion 193 . The first end 191 of the second elastic member abuts against the lower surface of the button 160 , the second end 192 of the second elastic member abuts above the bottom surface of the housing 110 , and the second elastic member surrounding portion 193 is sleeved on the third surface of the button 160 Two elastic parts are installed on the mounting part 164 . Therefore, the second elastic member 190 biases the button 160 toward the opening direction.

The specific structure of the lock tongue 175 is described with reference to FIG. 8 . The lock tongue 175 includes an engagement hole 176 and a transverse portion 177 . The engagement hole 176 is provided at the vertical lower end of the lock core 170 so that the lock tongue 175 is controlled and rotated by the lock core 170 . The transverse portions 177 are provided on both sides of the engaging portion 123 , and when the locking tongue 175 is rotated, the transverse portions 177 can engage with the hook portion 116 of the housing 110 to lock the handle 120 to the housing 110 .

The operation of the latching device 100 and the locking system including the latching device 100 is now described.

Referring to Figures 9A-9E, the latch device 100 is shown in a closed position. At this time, the handle 120 basically covers the top opening 117 of the housing 110 . The first pin 131 is close to the pivot end 121 of the handle 120 and is located in the end section 113b of the slide 113 . The second pin 132 is located near the middle of the arcuate segment 113a. Since the end section 113b is substantially perpendicular to the arc section 113a, or extends substantially vertically, when the latch device 100 is impacted, especially when it is subjected to a longitudinal impact from the first object 200 and the second object 300, the A pin 131 will not easily disengage from the end section 113b, thus contributing to the stability of the latch device 100.

The connecting member 150 is a component provided on the second object 300 , and its form may change according to the second object 300 . In this embodiment, the connecting member 150 is a vertically extending column, which is inserted into the housing 110 through the bottom wall 111 of the housing 110 and then inserted between the first pin 131 and the second pin 132, so it can be The first pin 131 or the second pin 132 is driven to move longitudinally relative to the housing 110 . An annular protruding annular portion 151 is provided at the periphery of the connecting piece 150 . When the latching device 100 is in the closed position, the annular portion 151 is inserted into the bottom wall 111 and engages the first section 115a of the opening 115 of the bottom wall 111 (see Figure 9E). Because the first section 115a has a smaller width, the annular portion 151 prevents relative vertical movement between the connector 150 and the housing 110 . In this way, the connector 150 secures the housing 110 and the first object 200 to the second object 300 .

The free end 122 of the handle 120 is held by the button 160. Specifically, the handle protrusion 127 is pressed by the side of the button 160, so that the handle 120 cannot rotate relative to the housing 110.

The transverse portion 177 of the locking tongue 175 engages the hook portion 116 of the housing 110 , also rendering the handle 120 unable to rotate relative to the housing 110 .

When the user needs to separate the first object 200 from the second object 300, that is, to open the latch device 100, he first rotates the lock cylinder 170 with a key (not shown), so that the lock tongue 175 Hook 116 is no longer engaged and button 160 is then depressed such that button 160 no longer presses against handle protrusion 127 . In this way, the handle 120 bounces up under the action of the first elastic member 180 and reaches the state shown in FIGS. 10A to 10E . At this time, the free end 122 of the handle 120 is lifted from the housing 110, and the first pin 131 moves to the connection between the arc section 113a and the end section 113b. The annular portion 151 of the connecting piece 150 has not yet detached from the first section 115 a of the opening 115 , so the housing 110 cannot yet detach from the connecting piece 150 , and the first object 200 cannot detach from the second object 300 .

The state shown in FIGS. 10A to 10E is a partially opened state of the handle 120 . In this embodiment, due to the resistance of the connecting member 150, when the handle 120 moves to the partially open state, the first elastic member 180 will not continue to bounce up the handle 120. It should be understood, however, that the latch device 100 need not be configured to stop the partially open state shown in FIGS. 10A-10E or any other partially open state. In the case where the latch device 100 is not engaged with the connecting piece 150 or the connecting piece 150 brings little resistance, the handle 120 can also be bounced by the first elastic member 180 to the fully open state shown in FIGS. 11A to 11E .

From the partially open position shown in FIGS. 10A to 10E , the user operates the free end 122 of the handle 120 so that the handle 120 rotates relative to the housing 110 to reach the state shown in FIGS. 11A to 11E .

At this time, the first pin 131 moves to near the middle of the arc segment 113a, the second pin 132 moves to the end of the arc segment 113a away from the pivot end 121, and the connecting member 150 is between the first pin 131 and the second pin. 132 moves longitudinally relative to the housing 110 (that is, moves toward the left side of FIGS. 11A to 11C ), so that the first object 200 moves longitudinally relative to the second object 300 . At this time, the annular portion 151 of the connecting member 150 has moved to the second section 115b of the opening 115, so the housing 110 can be vertically separated from the connecting member 150, and the first object 200 can be separated from the second object 300.

When the first object 200 is separated from the second object 300, the handle 120 forms a power-assisted lever. Specifically, the first pin 131 and the second pin 132 are provided at the pivot end 121 of the handle 120 nearby, and the connecting member 150 is driven by the first pin 131 and the second pin 132 (mainly driven by the first pin 131 during the opening process), while the user operates the free end 122 of the handle 120. Therefore, the connecting member 150 has a shorter moment arm relative to the pivot end 121 of the handle 120 , and the free end 122 has a longer moment arm relative to the pivot end 121 . In this way, the handle 120 forms a power-assisted lever, which helps the user to separate the first object 200 from the second object 300 and functions as a pulling aid. Moreover, the handle 120 provides an operating location convenient for applying force.

The process of detaching the first object 200 from the second object 300 is described above. It is easy to understand that when the user wishes to join the first object 200 to the second object 300, the above operations can be performed in reverse order. The handle 120 may also form a power assist lever when engaging the first object 200 to the second object 300 .

In summary, the present invention provides a latching device and a latching system that form a power-assisted lever to assist in engaging or disengaging a first object to or from a second object. On the premise of ensuring the basic functions of the latch device, the structure of the latch device is simplified as much as possible and the number of components of the latch device is reduced.

Although preferred embodiments have been illustrated and described herein, it is to be understood that these embodiments are given by way of example only. Many modifications, changes and substitutions will occur to those of ordinary skill in the art without departing from the spirit of the invention. The accompanying patent claims are therefore intended to cover all such variations falling within the spirit and scope of this creation.
