Description

Self-opening spring pressing device

The invention relates to a self-opening spring pressing device, in particular to a self-opening spring pressing device which can be opened by a press-and-open method.

In order for a drawer to smoothly enter and exit a hollow cabinet, a slide rail mechanism is generally installed on the left and right sides of the cabinet and the drawer. The slide rail mechanism usually uses two or three rails to stab each other. Set to have the function of sliding relative to each other. The drawer has a door panel on the front side.

As for the switch operation of the slide rail mechanism, there are two functional mechanical and electric types. As for the mechanical design, some are designed to press the door of the drawer to pop open, and some are designed to buffer and slow down when the drawer is closed. Design to avoid impact noise. For example, the US Patent No. 5040833 and the Taiwan Patent No. 201242540 are designed as an elastic structure at the bottom of the latching hook groove of the latching circuit, which are both improved for the mechanical press opening design. However, some push-pull type drawers are provided with a structure for positioning the drawers in the closed position. For example, Chinese patent application number 200680047010.4 shown in FIG. 1 uses a lockable ejection device 13 to engage an engaging element 15, When the drawer is pushed to close, and the engaging element 15 is pushed against one of the receiving elements 14 of the pushing device 13 to the end, a first restoring force is released and drives the receiving element 14 together with an anti-locking member 16 on the other side. The engaging element 15 is fastened to locate the drawer. When the drawer needs to be opened, the drawer only needs to be pressed again to release a second restoring force and push the drawer out. However, when the anti-locking fastener 16 is engaged, some users will not know that they must press to open, or when the second restoring force cannot be released smoothly and the drawer cannot be pressed smoothly, the drawer is forcibly opened, which will easily cause component damage. .

Therefore, how to make the drawer open normally and smoothly when it is opened by pressing and ejecting, so that the drawer cannot be forcibly opened by hand when the failure of the drawer opening failure occurs, so it is necessary to make a flexible and detachable design on the structure. This is from the conventional press-open slide rail. The lock loop is provided with a locking hook groove and the push-up energy is stored during the closing stroke. At the same time, a rotating anti-locking fastener is provided to reverse the push-up energy storage push-back positioning drawer. Two structures that are not displaced in the closed state, use two structures or one of them as the positioning function when the drawer is closed, and when the drawer is to be opened, when the door panel on the front side is pressed, it is often not in the middle of the door panel. Only one side is popped out, but the other side is not unlocked, and it is still in the locked state. If you press it again, one side of the original tripping is reversed and the other side is unlocked. Button, so the door panel is repeatedly pressed, and the door panels are in a state where the slope cannot be opened. Therefore, although the above problem is solved with a flexible structure as a design that can be forcibly detached, it is urgent for consumers to use it, but This kind of structure can withstand many times of forced disengagement during locking for a long time, which will cause the locking hook groove or the anti-locking fastener to deform and fail. As a result, the drawer cannot be closed due to the spring's restoring force. The component must be updated, and then the original existence cannot be repeated. The problem to be solved, so how to solve this problem is one of the focus of the industry's research and development. In addition, during the drawer opening and closing process, some components may collide with each other, and reducing collision noise and component damage caused by the collision is also a subject that requires efforts.

Accordingly, it is an object of the present invention to provide a self-opening spring pressing device which can overcome at least one of the disadvantages of the prior art.

Therefore, the self-opening spring pressing device of the present invention is suitable for being installed between a slide rail mechanism, the slide rail mechanism includes a fixed rail unit, and an energy storage direction and a different energy storage direction along the fixed rail unit.

The elastic mechanism is used for accumulating elastic force and providing a recovery elastic force in the direction of releasing energy.

When the push seat mechanism and the energy storage member receive an external force in the direction of the energy storage, the pushing surface pushes the pushed section of the energy storage member, and the walking column section of the energy storage member walks on the storage. The elastic mechanism accumulates elastic force. When the walking column section of the energy storage member moves to the curved track to cause the pushed section to rotate away from the pushing surface, the elastic mechanism releases the restoring elastic force and the swinging member resists the pushing column The first buffer member is pushed against the movement, and thus the restoring elastic force released by the elastic mechanism is buffered.

The elastic force is restored, and the elastic force is restored in the first and second stages, which will be described later. The spring mechanism 4 includes a plurality of springs 41 extending along the energy storage direction 91 and capable of being stretched. Each spring 41 includes a first spring portion 411 connected to the base 32 and a first spring portion 411 connected to the sliding cover 31. Two spring sections 412.

When the present invention is used, the drawer together with the moving rail unit 12 (Fig. 2), the pushing seat mechanism 2 can be switched between an energy storage starting state as shown in Figs. 6, 7, and 8 and a closed state as shown in Fig. 11. Referring to FIGS. 6, 7 and 8, when the energy storage is started, the drawer is opened, the slide cover 31 is located at an energy storage starting position, and the latching section 333 of the locking member 33 is located at the energy storage channel 51. As a starting point for energy storage, the walking column segment 344 of the energy storage element 34 is located at the energy storage starting point X of the track unit 6. The protruding post 346 of the energy storage member 34 is located at the entrance of the guide passage 237. The pushing post 372 of the swinging member 37 is located at the starting point of the first channel 324 of the buffer circuit unit 323.

6, 8 and 9, when the drawer is to be closed, as shown by arrow A in FIG. 6, the drawer is pushed toward the energy storage direction 91, and the moving rail unit 12 (FIG. 2) and the pushing seat mechanism 2 are also received toward the An external force in the energy storage direction 91 moves. The pushing member 28 pushes the pushing member 23 toward the energy storage direction 91. The pushing surface 233 of the pushing member 23 pushes against the pushed section 343 of the energy storage member 34, and the protrusion 346 of the pushed section 343. Will walk on the guide channel 237 of the pusher 23, the walking column section 344 of the energy storage member 34 walks on the energy storage track 61 of the base 32 and there is a relative movement between the storage pin section 333 and the The second pivoting section 342 of the energy member 34 can be pivotally assembled with the joint portion 316 of the top wall 311, so that the movement of the energy storage member 34 will also move the slide cover 31. The spring 41 is stretched to accumulate elastic force. Wherein, since the locking member 33 is pivotably combined with the base 32, and the latching section 333 of the locking member 33 projects into the energy storage passage 51, the sliding cover 31 faces the energy storage direction 91. During the movement, the latching section 333 of the locking member 33 will relatively approach the turning slope block 53 from the side of the energy storage passage 51 far from the turning slope block 53. Referring to FIG. 10, the latching section 333 enters the trip path 55, and the elastic force accumulated and stretched by the elastic mechanism 4 during this process is the first-stage recovery elastic force. In addition, when the pushing member 23 moves, the resetting member 29 also moves. In FIGS. 9 and 10, the pushed portion 292 is exposed on the sliding cover 31. In the process of FIG. 6 to FIG. 9, the swinging member 37 also moves toward the energy storage direction 91. The thrusting post 372 walks along the first passage 324 of the buffer circuit unit 323 and gradually approaches the first buffer member 36. .

Referring to FIGS. 10 and 11, the walking column segment 344 of the energy storage member 34 walks from the position of FIG. 10 to the position of FIG. 11, that is, walks to the curved track 62 and rotates so that the pushed section 343 completely separates from the pushing surface 233. The elastic mechanism 4 immediately releases the first-stage recovery elastic force and drives the slide cover 31 to move toward the energy release direction 92. The slide cover 31 further moves relative to the locking member 33 to move the latch section 333 to The latching hook groove 531 is used to fix the sliding cover 31 at a completed energy storage position (FIG. 11). At this time, the protruding post 346 abuts the pushing portion 235 of the pushing member 23, and the receiving member of the reset member 29 The pushing portion 292 is hidden in the sliding cover 31, and the drawer and the pushing seat mechanism 2 are switched to the closed state of FIG. 11. At this time, the walking column section 344 is not subject to any external force because the latching section 333 is locked in the latching hook groove 531, and the second pivoting section 342 of the energy storage member 34 is embedded in the combination of the sliding cover 31. In the portion 316, the walking column segment 344 is located at the energy storage end point Y of the track unit 6, and stops freely on the curved track 62 and swings freely. The relative movement distance between the slide cover 31 and the bayonet section 333 is actually very small, about several millimeters (mm). It is worth mentioning that when the pushed section 343 is released from the pushing surface 233 and the first-stage recovery spring force is generated, it will no longer interfere with the pushing member 23 and the pushing member 28 that are linked with the pushing surface 233. This is equivalent to the drawer not Moving in the opening direction, the case does not need to be restrained by anti-lock mechanism. In addition, it should be noted that the latching circuit unit 5 of the present invention can also omit the trip path 55, and make the latching section 333 directly move from the energy storage starting point to the latching hook groove 531 by a curvature structure, and It is not necessary to enter the tripping lane 55 before moving to the latching hook groove 531.

It is worth mentioning that, in the process of FIGS. 10 to 11, the thrust column 372 continues to walk along the buffer circuit unit 323, and has been turned to the second channel 325. The thrust column 372 of the swing member 37 is pushed. The tooth portion 361 of the first buffer member 36 is contacted, thereby pushing the first buffer member 36 to rotate. Therefore, in the process in which the elastic mechanism 4 releases the first-stage recovery elastic force to move the latching section 333 to the latching hook groove 531, the swing member 37 must push the first buffer member 36, and thus is subject to the first The buffering force of the buffering member 36 is blocked, and the swinging member 37 is combined with the slide cover 31, so the speed of the slide cover 31 moving toward the energy release direction 92 due to the first-stage recovery elastic force will be slower, making the latch The segment 333 enters the latching hook groove 531 at a slower speed and a smaller force, and does not hit the latching hook groove 531 at once. This can reduce the noise generated by the collision of the components, and can reduce the impact force to slow down. Damage to components, which can extend component life. Furthermore, the first buffer member 36 can be coated with damping oil to increase the blocking force when the first buffer member 36 is rotated, so that a better buffering force can be generated.

The present invention provides two ways to open the drawer, one is to pull directly forward (that is, toward the energy release direction 92) to open, and the other is to press the drawer backward (that is, toward the energy storage direction 91) to make it automatically forward Pop up. Referring to FIGS. 11 and 12, the method of pulling forward and opening is described first. When the user pulls the drawer toward the energy release direction 92, the moving rail unit 12 (FIG. 2) receives an external force in the energy release direction 92. The pusher 28 and the pusher 23 are not fixed, so in the state of FIG. 11, it is possible to open the drawer directly as shown in FIG. 12, so that the movable parts such as the pusher 28 and the drawer are directed toward the The energy release direction 92 moves, and at this time, the pushing member 23, the sliding cover 31 of the spring mechanism 3, and the energy storage member 34 will not move. Also, because the present invention is not provided with an anti-locking fastener, the drawer can be directly opened quite smoothly, and there is no problem that the drawer can be opened by strong pulling. That is, the drawer is pulled directly forward, so that the moving rail unit 12 (FIG. 2) is subjected to a full free stroke pulled in the release direction 92. During this process, the reset member 29 is in a hidden state, and the card The pin section 333 and the latching hook groove 531 are still in a state of being engaged with each other. When the drawer is to be closed later, the drawer can be directly closed by pushing it toward the energy storage direction 91.

Referring to FIGS. 11 and 13, a process of automatically opening a drawer by using a press-and-pop method is described next. First press the drawer toward the energy storage direction 91 (equivalent to the external force in the energy storage direction 91 of the moving rail unit 12 (FIG. 2)), and then link the pusher 28 and the pusher 23 in the state of FIG. 11 Move toward the energy storage direction 91 to the state of FIG. 13. In this process, the pushing portion 235 pushes the protrusion 346 of the pushed section 343, and the latching section 333 of the locking member 33 moves out of the locking hook groove 531. , And is pushed by the ejection surface 541 of the ejection block 54 to enter the starting point of the energy release channel 52 (FIG. 13), the state where the slide cover 31 was originally positioned by the latching section 333 is released, and the elastic mechanism 4 The spring 41 is stretched longer. At this time, the elastic force accumulated by the elastic mechanism 4 is the second-stage recovery elastic force.

Referring to FIGS. 14-16, when the external force pressed by the user in the energy storage direction 91 disappears, the second-stage recovery elastic force is released to drive the slide cover 31 to move toward the energy release direction 92, and the slide cover 31 moves toward FIG. 16 During the movement of the energy storage starting position, the pushed section 343 of the energy storage member 34 pushes against the pushing portion 235 of the pushing member 23, and the pushing member 23 pushes against the pushing member 28 and drives the reset The member 29 also moves in the energy release direction 92. The walking column section 344 of the energy storage member 34 enters the starting point of the energy storage track 61 via the energy release track 63. Specifically, in the state of FIG. 14, the pushed portion 292 of the reset member 29 protrudes from the slide cover 31 again, and the walking column segment 344 is located in the idle region 631 of the track unit 6, the idle region The form of 631 (refer to FIG. 8) has a blocking effect, so that the walking column segment 344 will stay in the idle zone 631 for a short time. At this time, the elastic force of the elastic mechanism 4 cannot temporarily pull the sliding cover 31, and the sliding cover 31 The pushing member 23 and the resetting member 29 do not move temporarily, and the pushing member 28 will continue to move toward the energy releasing direction 92 due to inertia, and the pushing member 28 will move toward the releasing direction 92 as shown by arrow C in FIG. 14. The impact pushes the pushed portion 292 of the reset member 29, and as shown in FIG. 15, the reset member 29 pulls the push member 23 and the sliding cover 31 to continue to move toward the release direction 92, and the walking column segment 344 will pass In the idle zone 631, the elastic force of the elastic mechanism 4 can thus pull the sliding cover 31 again, and finally the sliding cover 31 returns to the energy storage starting position of FIG. 16, and the walking column segment 344 is located at the energy storage starting point X, The latching section 333 of the locking member 33 has moved back to the starting point of the locking circuit unit 5, and the pushed portion 292 of the reset member 29 is hidden. Hiding in the slide cover 31 allows the pushing member 28 to pass, and the pushing member 28 will continue to move toward the energy release direction 92 due to inertia, so that the drawer is completely opened. The pushing post 372 of the swinging member 37 moves back to the starting point of the first passage 324 through the third passage 326. The subsequent process of closing the drawer, as described above, will drive the sliding cover 31 to move and cause the elastic mechanism 4 to accumulate the returning elastic force.

Referring to FIG. 17, during the process of FIGS. 14 to 15, the detailed position changes of the walking column segment 344 and the protruding column 346 are supplementarily explained. Firstly, a guide surface 65 is provided beside the guide channel 237 of the pushing member 23. The guide surface 65 has a first turning area 651 and a second turning area 652. When the walking column segment 344 is located in the position of FIG. 14, that is, in the idle zone 631, then the pushing member 28 hits the pushed portion 292 to drive the pushing member 23 and the sliding cover 31 to move, and the protruding column 346 It will relatively move from the position of FIG. 14 to the position of the first flow of FIG. 17. At this time, the protruding column 346 almost passes the first turning area 651, and the walking column segment 344 will soon pass the idle area 631. Then, as shown in the second flow of FIG. 17, the protruding post 346 moves to the second turning area 652, the walking post segment 344 has completely passed the idle zone 631, and can then move to the position of FIG. 16. To sum up, when the drawer is automatically opened using the push-to-open method, when the moving rail unit 12 (FIG. 2) receives an external force in the energy storage direction 91, the elastic mechanism 4 (FIG. 2) immediately releases the second stage Restore the elastic force, and drive the walking column segment 344 to reach the idle zone 631, and then assist the pulling by the reset member 29 to move the walking column segment 344 to the energy storage starting point X.

Referring to FIGS. 13, 18, and 14, for supplementary explanation, FIG. 18 is an intermediate process in which FIG. 13 is converted to FIG. 14, that is, a process in which the elastic mechanism 4 releases the second-stage recovery elastic force. In the process of FIG. 13 to FIG. 18 to FIG. 14, when the moving rail unit 12 (FIG. 2) receives an external force in the energy storage direction 91, the latching section 333 of the locking member 33 enters through the latching hook groove 531. In the energy release channel 52 (Fig. 13), when the external force disappears, the elastic mechanism 4 releases the restoring elastic force to drive the slide cover 31 to move toward the energy release direction 92. The abutment post 372 of the swinging member 37 has walked to the In the third channel 326 (FIG. 18) of the buffer circuit unit 323, the abutment post 372 contacts one of the tooth portions 381 of the second buffer member 38, and further pushes the second buffer member 38 to rotate, thereby being subjected to the second buffer. The cushioning force of the member 38 is retarded, so the speed of the slider 31 moving toward the energy release direction 92 will be slower, so that each component moves at a slower speed, and the force and speed of the pushing member 28 against the resetting member 29 are subsequently It will also become smaller and slower, thereby reducing the collision noise of components and reducing component damage. The second buffer member 38 can be coated with a damping oil to increase the blocking force during rotation to generate a better buffering force.

It should be noted that the spirit of the present invention is to achieve the purpose of energy storage or energy release through the relative movement between the components. In actual implementation, it is not necessary to limit which components are moving, which components are not moving, and it is not necessary to limit the components to be close to each other Or stay away, as long as the same result as the present invention is achieved through the relative movement between the elements, it is the protection scope of the present invention.

In summary, the pushed section 343 of the energy storage member 34 can be moved toward the energy storage direction 91 by the pushing seat mechanism 2. The walking column section 344 of the energy storage member 34 cooperates with the track unit 6. The latching section 333 of the locking member 33 cooperates with the locking circuit unit 5 so that the moving rail unit 12 (FIG. 2) can smoothly move toward the energy storage direction 91 and the energy release direction 92. The swinging member 37 cooperates with the first buffering member 36 to cushion the first-stage returning elastic force, and can reduce the force of the bayonet section 333 when entering the latching hook groove 531, thereby reducing collision noise and mitigating components due to collision. Damage. Moreover, the assisted pulling of the resetting member 29 enables the walking column section 344 to pass through the idle zone 631 and move to the starting point of energy storage, so that the invention can be smoothly opened on drawers or furniture that can move along a unidirectional track. With closed. Moreover, since the present invention is not provided with an anti-locking fastener, when opening objects such as drawers, it can be opened directly by hand, and when the hand is opened, the energy storage member 34 is still in the collapsed position, so it will not affect The moving stroke of the moving rail unit 12 and the seat pushing mechanism 2 forwards, thereby improving the problem that when a drawer is positioned in a closed state with an anti-locking fastener in the past, a user may forcefully open the drawer and damage the component. Moreover, the present invention can also be opened by pressing and popping, which is quite convenient in use.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications and corresponding relationships made according to the scope of the patent application and the content of the patent specification of the present invention can be used. The reversal of the positions still falls within the scope of the invention patent.
