Auxiliary positioning device for slide assembly

Description

FIELD OF THE INVENTION

[0001] The present invention relates to an auxiliary positioning device, and more particularly, to an auxiliary positioning device for a slide assembly to control the slide assembly to be positioned by operation of the auxiliary positioning device when the slide assembly is to be closed.

BACKGROUND OF THE INVENTION

[0002] U.S. Patent No. 5,040,833 to Brunnert discloses a "Closing Device For Drawers", which includes a drawer installed to a furniture body. The drawer is movable between a closed position and an open position, as shown in Figs. 2-6, 18a and 18b of U.S. Patent No. 5,040,833. A spring is located between the drawer and the furniture body. A holding member is fixed to the furniture body and has a front end. A latch member is fixed to the drawer and includes a first raised area and a second raised area, wherein the second raised area includes a notch which is located corresponding to the first raised area. The second raised area further includes an inclined guide track. When the drawer is located at the closed position relative to the furniture body, the front end of the holding member is guided by the inclined guide track of the second raised area to be engaged with the notch of the second raised area. When the drawer applies a force relative to the furniture body, the front end of the holding member is guided by the guide track of the first raised area to be engaged with another guide track and is disengaged from the notch. The drawer is pushed by the force of the spring and moved to a self-opening position relative to the furniture body.

[0003] The front end of the holding member is in a free status when the drawer is opened relative to the furniture body and the holding member is disengaged from the latch member. In this status, when the drawer is pushed to its closed position, the drawer can only travel through the same processes to let the front end of the holding member engage with the notch of the latch member.

[0004] However, if the demand is that the holding member and the latch member do not have a locked relationship when the drawer is located at the close status, especially when the drawer has a self-closing function. The relationship between the holding member and the latch member has to be changed. The present invention provides an improved structure to include the functions which the conventional closing device does not have.

[0005] Another example of a self-opening device for a drawer is disclosed in US 7,347,515 B.

SUMMARY OF THE INVENTION

[0006] The present invention relates to a slide assembly with an auxiliary positioning device and comprises a first slide member and a second slide member which is longitudinally and slidably movable relative to the first slide member. The second slide member has a stored opening force relative to the first slide member when in a closed position. The auxiliary positioning device comprises a positioning member, a guiding base and a link member. The positioning member is pivotally connected to the first slide member and includes a pin member. The guiding base is attached to the second slide member and comprises a first passage, a first slot and a first wall, wherein the first wall has a first guide surface facing the first passage. The guiding base further comprises a second passage, a second slot and a second wall, wherein the second wall has a second guide surface facing the second passage. The guiding base further comprises a separation body having a guiding end which faces the first slot. The guiding base further comprises an engaging body having an engaging surface which has a portion facing the second slot. The guiding base further comprises a third passage, a third slot and a third wall, wherein the third wall has a third guide surface facing the rest portion of the engaging surface. The guiding base further comprises a fourth wall having a fourth guide surface. The link member is located corresponding to the positioning member.

[0007] When the second slide member is in a closed position relative to the first slide member, the pin member is located in a first path in the first passage of the guiding base.

[0008] When the second slide member applies a force relative to the first slide member, the pin member is guided by the first guide surface of the first wall and moves from the first path to the first slot. The pin member is located at a first position.

[0009] When the force is released, the pin member is guided by the guiding end of the separation body and moves from the first position to a second path in the second passage.

[0010] When the second slide member is retracted relative to the first slide member, the pin member is guided by the second guide surface of the second wall and moves from the second path to the second slot via the second passage. The pin member is located in a second position. When the second slide member is released, the pin member moves away from the second position and is engaged with the engaging surface of the engaging body and located in a third position.

[0011] When the second slide member further applies a force relative to the first slide member again, the pin member is guided by the third guide surface of the third wall and moves from the third position into the third slot. The pin member is located in a fourth position. When the second slide member is released, the pin member is guided by the fourth guide surface of the fourth wall.

[0012] When the second slide member moves relative to the first slide member, the link member pivots the positioning member by the movement of the second slide member.

[0013] The primary object of the present invention is to provide an auxiliary positioning device for a slide assembly to control the slide assembly to be positioned by operation of the auxiliary positioning device when the slide assembly is to be closed, such that the slide assembly is easily operated whenever it is closed or opened.

[0014] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] Referring to Figs. 1 and 2, the slide assembly of the present invention comprises a first slide member 10, a second slide member 12 longitudinally and slidably movable relative to the first slide member 10, a movable member 14 connected to the first slide member 10 and an auxiliary positioning device 16.

[0017] The first slide member 10 includes a bottom board 18.

[0018] The second slide member 12 includes a first connector 20 and a second connector 22.

[0019] The movable member 14 is linked to move by the first connector 20 of the second slide member 12. For example, when the second slide member 12 is retracted relative to the first slide member 10 as shown in Fig. 4, the movable member 14 is connected to a first elastic member 24 and includes a first force F1 in a first direction and the first force F1 applies to the second slide member 12. The movable member 14 is engaged with the first connector 20, such that the second slide member 12 has a self-closing function relative to the first slide member 10 by the force of the first elastic member 24. When the second slide member 12 applies a force to the first slide member 10, as shown in Fig. 5, the second slide member 12 is pushed to a distance, the first connector 20 is disengaged from the movable member 14 as shown in Figs. 6 and 7, and the force of the first elastic member 24 does not apply to the second slide member 12. In other words, the first force F1 that the movable member 14 applies to the second slide member 12 is released. As shown in Fig. 1, by a pushing member 26 to engage with the second connector 22 and a second elastic member 28 connected to the pushing member 26 for applying a second force F2 to the second slide member 12 in a second direction, the second slide member 12 has a self-opening function relative to the first slide member 10. When the second slide member 12 is in a retracted status relative to the first slide member 10, the second slide member 12 will store a force to pop out the second slide member 12. The dual functions, self-closing and self-opening functions, have been disclosed in the applicant's former European Patent Application 09165988.8 which is a reference when studying the present invention.

[0020] The auxiliary positioning device 16 comprises a positioning member 30 which is pivotably connected to the first slide member 10, a guiding base 32 attached to the second slide member 12, and a link member 34 movably connected to the first slide member 10.

[0021] The positioning member 30 includes a pin member 36 and a contact end 38 which is located at a different position from that of the pin member 36. The positioning member 30 is linked to move by the link member 34 to keep the pin member 36 at a specific position.

[0022] Referring to Figs. 2 and 3, the guiding base 32 comprises a first wall 40, a second wall 42, a third wall 44, a fourth wall 46, a connection wall 48, a separation body 50 and an engaging body 52. The connection wall 48 is connected to the first, second, third and fourth walls 40, 42, 44, 46. The first wall 40 and the separation body 50 define a first passage 54. The separation body 50 and the engaging body 52 define a second passage 56. The engaging body 52 and the fourth wall 46 define a third passage 58. The separation body 50 has a guiding end 60. The engaging body 52 includes an engaging surface 62 which is a recessed area. The first, second and connection walls 40, 42, 48 define a first slot 64a. The second, third and connection walls 42, 44, 48 define a second slot 64b. The third, fourth and the connection walls 44, 46, 48 define a third slot 64c. The third slot 64c faces the third passage 58. The first wall 40 has a first guide surface 66 in the longitudinal direction facing a portion of the first passage 54 so as to guide the first passage 54 to face the first slot 64a. The second wall 42 has a second guide surface 68 in the longitudinal direction facing a portion of the second passage 56 so as to guide the second passage 56 to face the second slot 64b. The third wall 44 has a third guide surface 70 in the longitudinal direction facing a portion of the engaging surface 62 of the engaging body 52. The fourth wall 46 includes a fourth guide surface 72 so as to guide the pin member 36 of the positioning member 30 to face the second passage 56. A portion of the guiding end 60 of the separation body 50 faces a portion of the first slot 64a in the longitudinal direction so as to guide the first slot 64a to face the second passage 56. The rest portion of the engaging surface 62 of the engaging body 52 faces the second slot 64b in the longitudinal direction. In this embodiment, the engaging body 52 further includes a fifth guide surface 74 which faces the second passage 56.

[0023] The link member 34 is moved by the movable member 14. The link member 34 has an operation end 76 to lean against the contact end 38 of the positioning member 30. As shown in Figs. 1 and 3, the positioning member 30 is pivoted by the link member 34 and rotated an angle relative to the first slide member 10.

[0024] Referring to Fig. 4, the second slide member 12 is in a retracted position relative to the first slide member 10. The pin member 36 of the positioning member 30 is located in a first path R1 relative to the first passage 54 of the guiding base 32 and the first force F1 of the movable member 14 applies to the second slide member 12 so that the second slide member 12 is maintained in the retracted position relative to the first slide member 10.

[0025] Referring to Fig. 5, the second slide member 12 applies a force to the first slide member 10, the guiding base 32 moves relative to the positioning member 30 and the pin member 36 of the positioning member 30 is guided by the first guide surface 66 of the first wall 40 of the guiding base 32 from the first path R1 in the first passage 54 to the first slot 64a of the guiding base 32, and the pin member 36 is located at a first position P1.

[0026] When the force that the second slide member 12 applies to the first slide member 10 is released, the first connector 20 of the second slide member 12 is disengaged from the movable member 14 so that the first force F1 from the first elastic member 24 no longer applies to the second slide member 12. The pushing member 26 and the second elastic member 28 apply the second force F2 to the second connector 22 of the second slide member 12 (referring to Fig. 1 and the disclosure in European Patent Application 09165988.8). The second slide member 12 is automatically opened relative to the first slide member 10. As shown in Figs. 6 and 7, the guiding base 32 is moved together with the second slide member 12 relative to the positioning member 30, the pin member 36 of the positioning member 30 is guided by the guiding end 60 of the separation body 50 and moves from the first position P1 in the first slot 64a to a second path R2 via the second passage 56 of the guiding base 32. In this status, the second slide member 12 freely pops out and can be pulled out relative to the first slide member 10.

[0027] When the force applied to the first slide member 10 by the second slide member 12 is released, the second slide member 12 only pops out a small distance relative to the first slide member 10. If the second slide member 12 is not pulled out and moves the movable member 14, the second slide member 12 is pushed inward relative to the first slide member 10, as shown in Fig. 8, the guiding base 32 is moved relative to the positioning member 30, and the pin member 36 of the positioning member 30 is moved from the second path R2 to the second slot 64b and located at a second position P2 by the guidance of the second guide surface 68 of the second wall 42 and via the second passage 56.

[0028] Fig. 9 shows the action following the status in Fig. 8. When the force applied to the second slide member 12 is released, the second slide member 12 will drive the guiding base 32 relative to the first slide member 10 to move from the positioning member 30 by the second force F2. The pin member 36 of the positioning member 30 moves away from the second position P2 and is engaged with the engaging surface 62 of the engaging body 52 so as to be positioned at a third positioning P3.

[0029] When the second slide member 12 is popped out relative to the first slide member 10 and the second slide member 12 is not pulled relative to the first slide member 10 to a distance for moving the movable member 14 to a position that stores a force to return the second slide member 12 automatically, by changing the path between the pin member 36 in the first passage 54 and the second passage 56 as well as the pin member 36 to engage with the engaging surface 62 of the engaging body 52, the second slide member 12 can be pushed inward relative to the first slide member 10 and maintained at the retracted position. Accordingly, the second slide member 12 has no need to be pulled out for a longer distance relative to the first slide member 10.

[0030] When the second slide member 12 applies a push force relative to the first slide member 10 again, as shown in Fig. 10, the guiding base 32 moves relative to the positioning member 30 and the pin member 36 is guided by the third guide surface 70 of the third wall 44 from the engaging surface 62 of the engaging body 52 to the third slot 64c of the guiding base 32. The pin member 36 is then located at a fourth position P4. In this status, when the second slide member 12 is released again, the second slide member 12 freely pops out or is pulled out to a further distance relative to the first slide member 10, as shown in Fig. 11. The pin member 36 moves along the fourth guide surface 72 of the fourth wall 46 of the guiding base 32. When the second slide member 12 is further pushed inward relative to the first slide member 10 again, the pin member 36 is guided by the fifth guide surface 74 of the engaging body 52 and enters the second passage 56.

[0031] Fig. 12 shows that when the second slide member 12 is pulled out relative to the first slide member 10 and the movable member 14 is moved to a position that stores sufficient return force to bring the second slide member 12, the link member 34 is moved by the movement of the movable member 14. The operation end 76 of the link member 34 leans against the contact end 38 of the positioning member 30 to pivot the positioning member 30 to move the pin member 36 back to the first passage 54, which corresponds to the first path R1. Accordingly, when the second slide member 12 is retracted relative to the first slide member 10, the second slide member 12 is back to the status as shown in Fig. 4.

[0032] Fig. 13 shows a second embodiment of the present invention, wherein the movable member 200 includes a link member 202 which extends to the positioning member 30. When the second slide member 12 is pulled out, relative to the first slide member 10, to the position that can be automatically retracted as mentioned above, the positioning member 30 is pivoted by the link member 202 and the pin member 36 of the positioning member 30 is located in the first path R1.

[0033] Fig. 14 shows a third embodiment of the present invention, wherein a link member 300 is fixed to the second slide member 12 and located corresponding to the positioning member 30. When the second slide member 12 is pulled out, relative to the first slide member 10, to the position that can be automatically retracted as mentioned above, the positioning member 30 is pivoted by the link member 300 and the pin member 36 of the positioning member 30 is located in the first path R1.

[0034] Fig. 15 shows a fourth embodiment of the present invention, which includes a guiding base 400 and a connection board 402. The guiding base 400 includes a pair of engaging portions 404 and an engaging hole 406. The connection board 402 includes a pair of engaging slots 408 and an engaging member 410 corresponding to the engaging hole 406 so as to position the guiding base 400, as shown in Fig. 16. In this embodiment, the connection board 402 is connected to the second slide member 12 such that the guiding base 400 is connected to the second slide member 12.

[0035] Figs. 17 and 18 show a fifth embodiment of the present invention, which includes a guiding base 500, a connection board 502, an adjusting member 504 and a pivot member 506. The guiding base 500 includes a protrusion 508, a connection member 510, a longitudinal groove 512, and a recess 514. The connection board 502 includes a first longitudinal slot 516, a second longitudinal slot 518, a fixing hole 520 and a protruding portion 522. The protrusion 508 extends beyond the first longitudinal slot 516. The connection member 510 is inserted in the second longitudinal slot 518. The protruding portion 522 is engaged with a portion of the recess 514 so that the guiding base 500 is movably connected to the connection board 502 and moves longitudinally. The adjusting member 504 includes an aperture 524 and a spiral recess 526. The pivot member 506 extends through the aperture 524 of the adjusting member 504 and is connected with the fixing hole 520 of the connection board 502, such that the adjusting member 504 is rotatable relative to the connection board 502.

[0036] Figs. 19 and 20 show the assembled configuration of the fifth embodiment. A portion of the second slide member 12 is connected with the longitudinal groove 512 of the guiding base 500. The connection board 502 is fixed to the second slide member 12. The protrusion 508 of the guiding base 500 is movable in the spiral recess 526. When the adjusting member 504 is rotated by the user, the protrusion 508 of the guiding base 500 will be moved in the spiral recess 526 and the guiding base 500 will be moved longitudinally relative to the connection board 502. Therefore, when the guiding base 500 is adjusted to move longitudinally relative to the second slide member 12 by operation of the adjusting member 504, a relative position between the guiding base 500 and the positioning member 30 is adjusted. Besides, this embodiment further includes a third elastic member 528 and a stop 530 which is urged by the third elastic member 528 to be contact with an end outside of the longitudinal groove 512 of the guiding base 500, such that the depth in the longitudinal direction of the second slide member 12 relative to the first slide member 10 can also be adjusted. This allows the assemblers to micro-adjust the depth of the drawer in the furniture.

[0037] Fig. 21 shows a sixth embodiment of the present invention, wherein a roller 602 is connected to a guiding base 600 and the roller 620 has a rolling surface facing the bottom board 18 of the first slide member 10. When the load in the drawer applies to the second slide member 12, the second slide member 12 slightly moves downward relative to the first slide member 10, the rolling surface of the roller 602 is supported between the guiding base 600 and the bottom board 18 of the first slide member 10 so as to ensure that the guiding base 600 is maintained at a position relative to the positioning member 30.

[0038] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
