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 No. 200680047010.4 shown in FIG. 32 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.

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 self-opening spring pressing device includes a pushing rail mechanism, a spring pressing mechanism, and a spring mechanism.

The pushing mechanism includes a pushing member, and the pushing member has a pushing surface. The spring mechanism includes a lock circuit unit, a lock member, an energy storage member, an energy storage track, and a curved track on one side of the energy storage track. The lock circuit unit includes an energy storage channel, An energy release channel and a latching hook groove provided in the energy storage channel. The locking member includes a bayonet section that moves and swings freely between the energy storage channel and the energy release channel. The energy storage component includes an energy storage device. A pushed section pushed by the pushing surface of the pushing member, and a walking column section moving between the energy storage track and the curved track. The elastic mechanism is used for accumulating elastic force and providing a first-stage recovery elastic force and a second-stage recovery elastic force toward the energy release direction.

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 segment of the energy storage member moves to the curved orbit to cause the pushed segment to rotate away from the pushing surface, the elastic mechanism immediately releases the first-stage recovery elastic force and drives the The latching pin segment and the latching hook groove move relative to each other and buckle with each other, and the walking column segment is located on the curved track because the latching pin segment is latched in the latching hook groove.

The effect of the present invention is that the pushed section of the energy storage member can be moved toward the energy storage direction by the pushing seat mechanism, the walking column section of the energy storage member cooperates with the energy storage track and the curved track, and the lock The buckle section of the fastener is matched with the locking circuit unit, so that the moving rail unit can smoothly move toward the energy storage direction and the energy release direction, so that the invention is applied to a drawer or furniture that can move along a unidirectional track On, it can be opened and closed smoothly.

When the present invention is used, the drawer together with the moving rail unit 12 and the pushing seat mechanism 2 can be switched between an energy storage starting state as shown in FIGS. 7 and 8 and a closed state as shown in FIG. 10. Referring to FIGS. 7 and 8, when the energy storage is started, the mobile rail unit 12 projects forward relative to the fixed rail unit 11. At this time, the drawer is opened, the slide cover 31 is located at an energy storage starting position, and the lock The position of the latching section 333 of the fastener 33 in the energy storage passage 51 is an energy storage starting point, and the walking post section 344 of the energy storage member 34 is located on a side of the energy storage track 61 away from the curved track 62.

Referring to FIGS. 8 to 10, when the drawer is to be closed, as shown by arrow A in FIG. 8, the drawer is pushed toward the energy storage direction 91, and the moving rail unit 12 and the pushing seat mechanism 2 are also subjected to external force toward the energy storage direction 91 While moving. When the pushing base mechanism 2 moves, the pushing surface 233 of the pushing member 23 pushes against the pushed section 343 of the energy storage member 34, and the walking column section 344 of the energy storage member 34 moves on the base 32 There is a relative movement between the energy storage track 61 and the bayonet section 333, and the second pivotal connection section 342 of the energy storage member 34 is pivotably assembled with the joint portion 316 of the top wall 311. The movement of the energy member 34 will also move the slide cover 31, and the springs 41 of the spring mechanism 4 are stretched to accumulate spring force. Wherein, since the locking member 33 is pivotably combined with the base 32, and the bayonet section 333 of the locking member 33 extends into the energy storage passage 51, the sliding cover 31 faces the energy storage direction 91. During the movement, the locking member 33 pivotally moves along the channel shape of the energy storage channel 51. The latching section 333 of the locking member 33 moves away from the turning slope 53 from the energy storage channel 51. On one side, it gradually approaches the turning slope block 53. When the walking column section 344 of the energy storage member 34 moves to the curved track 62 to cause the pushed section 343 to rotate away from the pushing member 23, the bayonet section 333 of the locking member 33 has been moved by the turning slope block 53. Move to the trip path 55 (as shown in FIG. 9), and the elastic force accumulated by the elastic mechanism 4 during this process is the first-stage recovery elastic force, and then the elastic mechanism 4 immediately releases the first-stage recovery elastic force and drives The sliding cover 31 moves toward the release direction 92, and the sliding cover 31 and the locking member 33 are relatively moved, so that the latching section 333 is moved to the locking hook groove 531 to fix the sliding cover 31 to Upon completion of the energy storage position (FIG. 10), 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 because of the second pivoting section 342 of the energy storage member 34 Embedded in the joint portion 316 of the sliding cover 31, the walking column segment 344 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). The pushing member 23 can still continue to move toward the energy storage direction 91 due to the external force, and finally contacts the energy releasing pushing surface 315 of the energy releasing wall 314, so that the drawer, the moving rail unit 12, and the pushing seat mechanism 2 are converted to This closed state of FIG. 10. It is added that after the slide cover 31 is fixed at the completed energy storage position, the pushing member 23 can still continue to move in the energy storage direction 91 under external force. The external force may refer to the pushing force applied by the user to the drawer or Thrust from other sources, or forward force, low tilt force, or external force such as elastic force.

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. 10 and 11, the method of pulling forward and opening is described first. When the user pulls the drawer toward the energy release direction 92 as shown by arrow B in FIG. 10, the moving rail unit 12 is linked by an external force in the energy release direction 92. The pushing member 23 moves relative to the energy storage member 34 and the sliding cover 31, and the pushed section 343 of the pushing member 23 and the energy storage member 34 still maintains a detached state during the relative movement, wherein the energy storage The pusher 34 is in the collapsed position shown in Figs. 10 and 11, and its pushed section 343 does not interfere with the moving stroke of the pusher 23. When the pusher 23 moves toward the release direction 92, the pusher 23 and the pusher 23 The energy storage elements 34 can pass through each other freely. This way of opening the drawer will not move the sliding cover 31 in a linked manner, so when the drawer, the moving rail unit 12 and the push base mechanism 2 move back to the state of FIGS. 7 and 8, the sliding cover 31 is still located at the position of FIGS. 10 and 11. The completed energy storage position. 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. 10 and 12, the opening method of the drawer pressing and popping out is described next. When the drawer, the moving rail unit 12, and the pushing mechanism 2 are located in the closed state shown in the first flow of FIG. 10 and FIG. 12), The drawer is pressed toward the energy storage direction 91, and then the pushing mechanism 2 is moved to the second flow state of FIG. 12 as shown in the direction of arrow C in FIG. 12, so that the spring 41 of the elastic mechanism 4 is stretched longer. At this time, the elastic force accumulated by the elastic mechanism 4 is the second-stage recovery elastic force. The moving rail unit 12 receives an external force (ie, a user's pressing force) in the direction of the energy storage 91 to interlock the pushing member 23 and the energy releasing pushing surface 315 of the energy releasing wall 314 with each other. The latching section 333 of the piece 33 moves out of the latching hook groove 531 and is pushed by the ejecting surface 541 of the ejecting block 54 to enter the energy release channel 52. At this time, the slide cover 31 was originally received by the latching section. 333 positioning is released.

Referring to FIGS. 4, 13 and 14, when the external force pressed by the user disappears, the elastic mechanism 4 releases the second-stage recovery elastic force, so that the latching section 333 can walk on the sliding cover 31 and the energy storage member 34. The energy release channel 52 approaches the energy storage starting point (refer to the position of the bayonet section 333 shown in FIG. 8 in the energy storage channel 51), at the same time, the elastic mechanism 4 drives the slide cover 31 toward the energy release. The movement in the direction 92 causes the release pushing surface 315 of the release wall 314 to be simultaneously pushed by the second-stage recovery elastic force released by the elastic mechanism 4 to push the pushing member 23, and the sliding cover 31 will drive the pushing seat. The mechanism 2 and the moving rail unit 12 also move toward the energy release direction 92. The walking column segment 344 of the energy storage member 34 reaches the energy release track 63 and moves toward the energy release direction 92, and finally passes the one-way traffic gate. 66 and enters the energy storage track 61. When the rotation-restricting surface 234 of the pusher 23 contacts the energy storage member 34, one of the components that originally needed to abut against the energy storage unilaterally collapsed and passed through each other freely (see FIG. 14). , So that the pushing member 23 can flash past the energy storage member 34 and continue to move toward the energy release direction 92. Specifically, since the pushing member 23 of this embodiment can be pivoted, when the rotation limiting surface 234 of the pushing member 23 contacts the energy storage member 34, the movable portion 232 of the pushing member 23 can pivot in the counterclockwise direction. (See Fig. 14) and flashes through the energy storage member 34. After the pusher 23 and the energy storage member 34 have completely flashed, the pusher 23 is subjected to gravity, and the movable portion 232 is pivoted in a clockwise direction to return the pusher 23 to an upright state. Finally, the slide cover 31 is transferred to the energy storage starting position of FIGS. 7 and 8. The latch section 333 of the locking member 33 has moved to the side of the energy release channel 52 away from the turning slope block 53. The drawer Moved to on. 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 FIGS. 6, 8 and 13, it is worth mentioning that the one-way access gate 66 is provided in the base 32 of this embodiment, which can restrict the walking column segment 344 to only follow the energy storage track 61 in one direction. The curved track 62 and the release track 63 are sequentially moved. In the process of closing the drawer from the state of FIG. 8, when the energy storage track 61 moves in the energy storage direction 91, the walking column section 344 passes through the one-way gate 66 on the side of the gate portion 662 and receives the The gate portion 662 blocks the walking post 253 from entering the energy release track 63. When the drawer is opened by pressing and popping, the walking column segment 344 moves to the gate portion 662 on the energy release track 63 toward the energy release direction 92, and the walking column segment 344 moves above the one-way traffic gate 66 (FIG. 13), the gate portion 662 is elastically displaced downward, and the traveling column segment 344 can further enter the energy storage track 61. In addition, the energy storage passageway 51 is provided with the blocking areas 511, so that during the movement of the sliding cover 31, the latching section 333 can be limited to any one of the blocking areas 511, and the sliding The lid 31 and the drawer are fixed in a half-opened state, and can be positioned in multiple stages. When an external force moves toward the closing direction while accumulating energy, due to the lack of external force, the external force disappears halfway without causing the drawer to open. Mobile design.

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 can smoothly move toward the energy storage direction 91 and the energy release direction 92, so that the present invention is applied to energy storage. Drawers or furniture moving along a one-way track can be opened and closed smoothly. 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.

15 to 18, a second embodiment of a self-opening spring pressing device according to the present invention has substantially the same structure as the first embodiment, and the main difference lies in the structure of the track unit 6 of the base 32. The track unit 6 of this embodiment includes an energy storage track 61 extending linearly along the energy storage direction 91 and a curved track 62 connected to one end of the energy storage track 61. When the sliding cover 31 moves from the energy storage starting position (FIG. 16) to the energy storage completion position (FIG. 18), the walking column segment 344 of the energy storage member 34 is relatively far from the energy storage track 61 away from the One end of the curved rail 62 is moved to the curved rail 62. In this process, the latching section 333 of the locking member 33 is the same as the first embodiment, and it can also enter the tripping channel 55 (FIG. 17) first, and When the pushed section 343 of the energy storage member 34 is disengaged from the pushing member 23, the elastic mechanism 4 releases the first-stage recovery elastic force to drive the sliding cover 31 and the locking member 33 to move relatively, so that the latching section 333 moves to the latching hook groove 531 (FIG. 18) to fix the slide cover 31 at the completed energy storage position, and the pusher 23 can still continue to move toward the energy storage direction 91 under external force. It should be noted that, in the implementation of the present invention, the trip path 55 can also be omitted, and the buckle section 333 can be directly moved from the energy storage starting point to the latching hook groove 531 by a curvature structure without entering the trip. Deduct 55.

Referring to FIGS. 18 and 19, when the sliding cover 31 moves from the completed energy storage position in FIG. 18 toward the energy storage starting position, the walking column segment 344 of the energy storage member 34 moves in reverse from the curved track 62 to enter The energy storage track 61 finally returns to the position shown in FIG. 19, and when the rotation-restricting surface 234 of the pushing member 23 contacts the energy storage member 34, the energy storage member 34 is pushed against the stored energy by the original need. One element collapsed in one direction and passed freely to each other. Specifically, the pushing member 23 of this embodiment can be pivoted, so that the pushing member 23 can pivot to flash the energy storage member 34 and then continue to move toward the energy release direction 92. It should be noted that the external structure of some components (such as the locking member 33, the energy storage member 34, and the push base mechanism 2) in this embodiment is slightly different from the first embodiment, but can achieve the same movement and position conversion. efficacy.

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.

20 to 23, a third embodiment of the self-opening spring pressing device of the present invention has substantially the same structure as the first embodiment, and the following mainly describes the differences. The pushing member 23 of the pushing base mechanism 2 includes the pushing surface 233, a guiding channel 237 formed on the bottom surface, a pushing portion 235 located beside the guiding channel 237, and a pushing surface 236. Wherein, the pushing surface 233 extends beside the guiding channel 27, and one end of the guiding channel 237 has an inlet. The pushing base mechanism 2 further includes a pushing member 28 for pushing the pushing surface 236. The pushing member 28 can be connected to a movable part such as a drawer through the moving rail unit 12 (FIG. 1). The pushed section 343 of the energy storage member 34 has a protrusion 346 protruding upward and capable of walking on the guide channel 237 of the pushing member 23. The latch circuit unit 5 of the third embodiment omits the stop region 511 (FIG. 8) in the first embodiment.

23 to 25, when the third embodiment is used, pushing the pushing member 28 in the energy storage direction 91 will drive the pushing member 23 and the energy storage member 34 to move. The process of the latching section 333 of the locking member 33 walking in the locking circuit unit 5 and the process of the walking column section 344 of the energy storage member 34 walking on the track unit 6 are substantially the same as those of the first embodiment. . In the energy storage starting state of FIGS. 23 and 24, the protrusion 346 of the energy storage member 34 is located at the entrance of the guide passage 237. When the sliding cover 31 is driven by the energy storage member 34 and moves from the energy storage starting position (FIG. 23) to the energy storage completion position (FIG. 27), the protrusion 346 of the energy storage member 34 walks on the guide. The passage 237 and the pushing surface 233 of the pushing member 23 push the pushed section 343 to move and store energy.

Referring to Figs. 26 and 27, the walking column segment 344 of the energy storage member 34 walks to the curved track 62 and rotates so that the pushed section 343 completely disengages from the pushing surface 233. The elastic mechanism 4 (Fig. 20) releases the first The spring force is restored at the stage, so that the latching section 333 is moved to the latching hook groove 531 (FIG. 27) to fix the slide cover 31 at the completed energy storage position. At this time, the protrusion 346 and the pushing force of the pushing member 23部 235 Abuts. 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.

Referring to FIGS. 27 and 28, the third embodiment can also pull the open drawer directly forward (that is, toward the energy release direction 92). Since the pushing member 28 and the pushing member 23 are not fixed, the In the state, the drawer can be opened directly forward as shown in FIG. 28, and the movable parts such as the pusher 28 and the drawer can be moved toward the energy release direction 92. At this time, the slide cover 31, the pusher 23, the energy storage member 34, etc. The component does 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.

Referring to Figs. 27 and 29, the third embodiment can also use a pop-up method to automatically open the drawer. When the pushing member 28 and the pushing member 23 are pressed toward the energy storage direction 91 in the state of FIG. 27, the pushing portion 235 pushes the protrusion 346 of the pushed section 343, and the latching section 333 of the locking member 33. After being pushed by the ejection surface 541 of the ejection block 54, it can enter the starting point of the energy release channel 52 (FIG. 29). At this time, the second stage recovers the elastic accumulation.

Referring to FIGS. 29 to 31, after releasing the pressing force applied to the pushing member 28, the second stage of restoring elastic force is released to drive the slide cover 31 to move toward the energy release direction 92, and the slide cover 31 faces the storage of FIG. 31. During the movement of the starting point 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 also moves in the direction of energy release. 92 moves, and finally the slide cover 31 returns to the energy storage starting position of FIG. 31. The pushing member 28 will continue to move toward the energy release direction 92 due to inertia (see FIG. 31), so that the drawer is fully opened.

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.
