Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a detachable drawer rail, particularly a detachable drawer rail having a holding device.

[0002]

[Prior art]

 Separable drawer rails are commonly used with computer desk drawers or keyboard racks and are mounted on the side of the drawer or similar mechanism to mount the drawer or rack on the desk. Conventional detachable drawer rails typically consist of a rolling bearing race slidably mounted between an intermediate track and an internal rail member for easy removal. In addition, a retaining device is secured to the detachable drawer rail to limit the drawer to the sliding range and to hold the drawer in place when the drawer is pulled out of the desk.

There are several types of conventional detachable drawer rails currently available. For example, the rails of the first conventional detachable drawer of FIGS. 6, 7, and 8 and the rails of the second conventional detachable drawer of FIGS. It includes a rail member slidably mounted and an elastic plate 90 attached to the rail member. The first and second conventional detachable drawer rails further include a bearing race mounted between the track 60 and the rail member 70 to more easily slide the rail member 70 on the track 60. 80.

Referring now to FIGS. 6-8 of a first conventional detachable drawer rail, track 60 is secured to the interior surface of a furniture compartment and bearing race 80 falls from track 60. Has a tab 64 fixed to one end of the track 60 to prevent the The track 60 further has a limit block 66 with two stop projections 662 fixed to the other end of the track 60 to prevent the rail member 70 from coming off the furniture completely.

The rail member 70 is formed so as to be fixed to the side wall of the drawer, and has an opening 72 in the center of the rail member 70. A mounting hook 74 and a stop block 76 are formed on one side and the other side of the rail member 70 near the opening 72, respectively. A recess 762 is formed in the rail member 70 near the base of the stop block 76.

The elastic plate 90 is flexible and has a front fork 92 formed at one end of the elastic plate 90 so that the mounting hook 74 of the rail member 70 is pushed in. The elastic plate 90 has a rounded bottom end 94 that cuts into the recess 762 of the rail member 70 and is stamped below the bottom side of the elastic plate 90. Therefore, the elastic plate 90 is detachably attached to the rail member 70.

Referring to FIG. 8, when the drawer is pulled out, a stop projection 662 is provided on the vertical holding plane to effectively prevent the drawer from being completely pulled out of the furniture compartment. At 666, the elastic plate 90 is blocked. When the drawer is released, the elastic plate 90 is pressed in the direction of the rail 70 so as not to contact the holding plane 666, and the engagement between the rail 70 and the track 60 is released.

However, when the user presses the elastic plate 90, the finger is often soiled with the oil applied to the members of the holding device. Moreover, the rounded nose end 94 of the resilient plate 90 is easily swung within the recess 72, destabilizing the entire holding device during use.

With respect to the second conventional detachable drawer rail shown in FIGS. 9-11, the track 60 is made to be secured to the interior surface of the furniture compartment, and the bearing race 80 falls off the track 60. A limit tab 64 is fixed at one end of the track to avoid inconvenience. Further, a limit block 66 having two stop projections 662 is fixed to the other end of the track 60 so that the rail member 70 does not slide completely out of the furniture compartment.

The rail member 70 is made to be fixed to the side wall of the drawer, and an opening 72 is formed in the center of the rail member 70. A lip 71 is formed in the rail member 70 near the opening 72, and a hole 73 is formed near the hole 72 on the rail opposite to the lip 71.

The elastic plate 90 is flexible and has a tab 91 formed at one end of the elastic plate 90 so that the lip 74 of the rail 70 is cut off. The elastic plate 90 further has a through hole 93 at the other end. The through hole 93 corresponds to the hole 73 of the rail member 70, and a pin 931 passes through the through hole 93 so that the elastic plate 90 can be detachably and securely attached to the rail member 70. In addition, two ports 95 are formed on both sides of the center of the elastic plate 90, respectively.

Referring to FIGS. 10 and 11, when the drawer is pulled outward, the elastic plate 90 is pushed downward against the stop protrusion 662 of the limit block 66. Next, the drawer stops when the stop protrusion 662 is held inside the port 95 of the elastic plate 90 shown in FIG. Since the pressing end portion 961 that advances against the stop projection 662 includes the guide-arc 963, the guide-arc 963 releases the stop protrusion 662 from the port 95 when the drawer is slightly pressed. Next, the drawer is pulled into the furniture compartment.

For this reason, the shape of the guide-arc 963, particularly its exact angle, is important. If the angle is too curved, the limit block 66 loses its positioning function and the drawer will move too much. Conversely, if the angle is not sufficiently curved, the user cannot easily push the drawer back into the compartment. In addition, since the pressing force for the guide / arc 963 to get over the elastic plate 90 acts in the axial direction, the elastic plate 90 itself is easily broken at the center and other places, particularly the tab 92.

[0017]

[Embodiment of the invention]

 Referring to FIG. 1, the detachable drawer rail comprises a U-shaped track 10, a bearing race 15, a rail member 20, and a resilient latch 30.

The track 10 is made to be fixed to the inner surface of the furniture compartment, and two guides 11 are formed on both side walls of the track 10, respectively. A limit tab 12 is formed at one end of the track 10 and a limit block 14 is fixed to the other end of the track 10. The limit block 14 is made of an elastic material such as rubber, and has stop projections 142 formed on both sides of one end of the limit block 14 perpendicular to the limit block 14. A pair of O-shaped limit bosses 141 are formed at one end of the limit block 14 facing outward from the rail member 20.

The rolling bearing race 15 is substantially U-shaped, and is movably mounted on the inner surface of the track 10 so that the rail member 20 can slide smoothly on the track 10.

Referring to FIGS. 1 and 2, a rail member 20 having a bottom is fixed to the side wall of the drawer and has a tapered end 21 for tightening the limit tab 12. A flange 211 is stamped inward from the bottom of the rail member 20 so that the rail member 20 presses the limit tab 12 inward against the track 10, and a hole 22 is formed in the center of the rail 20. Is formed. A stop edge 23 is formed at the end of the rail member 20 opposite the tapered end. A mounting hook 24 and a stop block 26 are formed on opposite sides of the hole 22. A recess 262 is formed in the rail member 20 near the base of the stop block 26. Further, since the tongue 28 is formed on the rail member 20 and is punched inward from the bottom of the rail member 20, it protrudes toward the track 10.

The elastic latch 30 is a strip having a branch 32 formed at one end and an inclined surface 33 at the other end. A small piece 34 having an abutment surface 341 is formed below the inclined surface 33, and the wing 35 projects laterally from each measuring portion of the inclined surface 33. As shown in FIG. 3, a groove 38 corresponding to the tongue 28 of the rail member 20 is formed on the inclined surface 33 of the elastic latch 30. Further, the ears 36 are formed laterally from each side of the center of the elastic latch 30, and as shown in FIG. 4, a gap A between the ear 36 and the elastic latch 30 is formed at the center. . Each ear 36 is divided into a lock 361 and a guide 363. The lock portion 361 has an arc shape, and forms a port 365 between the lock portion 361 and the blade 35 as shown in FIG. The guide portion 363 is a long strip, and is inclined inward toward the end where the branch 32 is formed. Further, two pivot bars 343 are formed on both sides of the small piece 34 so as to be in contact with the rail member 20 in order to easily press the elastic latch 30.

Referring to FIG. 3, the resilient latch 30 engages the fork 32 with the mounting hook 24 of the rail member 20 and pushes the small piece 34 into the recess 262 below the ramp 33. Thus, it is attached to the rail member 20. Next, the resilient latch 30 is pressed toward the rail member 20 and the pivot bar 343 exerts a lever force on the inclined surface of the resilient latch 30. Further, the tongue 28 of the rail member 20 is pressed into the groove 38 to enhance the positioning effect of attaching the elastic latch 30 to the rail member 20. The contact surface 341 is evenly in contact with the inner wall of the recess 262 so that the elastic latch 30 does not easily swing when the rail member 20 slides on the track 10.

As shown in FIG. 4, when the rail member 20 is pushed outward, the stopper projection 142 of the stopper block 14 slides along the guide part 363 and compresses the ear part 36 in the lateral direction. Therefore, the ear 36 is deformed so as to pass the elastic latch 30 between the stop projections 142 and enters the gap A. Each stop is then held in a port 365 between the wing 35 and the stop 361 of the ear 36 so that the rail member 20 is maintained in a fixed position.

When the rail member 20 is pushed inward so as to be released from the fixed position shown in FIG. 5, the stop protrusion 142 presses the ear portion 36 again by the lock portion 361, and the stop protrusion 142 is pressed by the elastic latch 30. Over the arc so as to release from port 365 of FIG.

According to the above description, it can be easily understood that the ear 36 of the elastic latch 30 provides a retaining effect so as to retain the stop projection in the port. The gap A easily deforms the ear 36 in the lateral direction as the ear 36 rubs the stop projection 142. Further, when the rail member 20 is completely pushed into the track 10 and received, the O-shaped limit boss 141 of the track is pushed so as to touch the stop end 23 of the rail member 20, and the rail member 20 has a cushioning effect. give.

In addition, the tongue 28 of the rail member 20 that fits into the groove 38 enhances the positioning effect of attaching the elastic latch 30 to the rail member 20. The small piece 34 having the abutment surface 341 contacts the inner wall of the recess 262 to provide a stable effect to prevent the elastic latch 30 from swinging and dropping off the rail member 20.
