Extended rod of slide mechanism for drawer slide track

Abstract

An extended rod of slide mechanism for drawer slide track comprises a control stop mounted on the extended rod and a stop stock mounted on the front of the slide track wherein the control stop is an integrally formed extrusion with a swing block fixed on the extended rod by a rivet. The swing block has a cut section at one end to stop the stop stock of the slide track. The extended front end of the swing block forms a push-pull section. Pushing or pulling the push-pull section will free the cut section from the stock causing the extended rod disengages the slide track and pull the drawer out of the slide track. Regardless whether the slide mechanism is installed on the right side or the left side of the drawer, it provides a disengaging direction, easy the operator to take the drawer out of the slide track.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the major components of the slide mechanism of the drawer, particularly the control stop operated to disengage and stop the extended rod from the slide track for the multiple drawer slide tracks.

2. Description of the Related Art

For the structure of multiple drawer slide tracks, when drawer is pulled out and the extended rod travels to the end of the slide track, there provides a stop mechanism on the join of the slide track and extended rod to control the stop operation, and prevents the extended rod falling off from the slide track. This stop mechanism consists of one control stop mounted at the end of the extended rod and a stop stock mounted on the slide track. If it is intended to disengage the extended rod from the slide track, use the stopping operation by the control stop and stop stock of the stop mechanism, the extended rod can be released from slide track smoothly.

As shown in FIGS. 1 through 4, it is the control stop 11′ of the prior art where the control stop 11′ is locked on the extended rod 1′ by a rivet 3′. The control stop 11′ has a guide section 111′ and a swing rod section 112′ extended at the rear side. The swing rod section 112′ has a cut section 113′ at the bottom of the front end, when the extended rod 1′ is installed on the slide track 2′, the stop stock 21′ and cut section 113′ will prevent the extended rod 1′ from disengaging the slide track 2.

The slide track is generally installed on both sides of the drawer. If it is intended to disengage the extended rod 1′ from the slide track 2, on the left side of the drawer, it is necessary to swing downward the swing rod section 112′ of the control stop 11′, so the cut section 113′ moves downward as shown in FIG. 3, the left side extended rod 1′ is freed from the stop stock 21′ of the slide track 2′ and can be pulled out the slide track 2′. For the control stop 11′ of the right side extended rod 1′ is necessary to swing upward by the swing rod section 112′ to control the cut section 113′ swing upward as shown in FIG. 4, the right side extended rod 1′ is free released from the stop stock 21′ of slide track 2′, This practice of disengaging the extended rod 1′ from the slide track 2′ differing the control stop 11′ of the extended rod 1′ in left and right sides which renders too much inconvenience on the disassembly. It requires prompt improvement.

In order to accomplish a uniform practice, a new control stop of slide mechanism was invented as shown in FIG. 5, the U.S. Pat. No. 5,169,238 in which the extended rod 1′ has a stop section 4′ with a V slot 41 and an independent pull board 5′ comprised a control stop. When the extension section 51 ′ of the pull board 5′ is pushed into the V slot 41′, both sides of the stop sections 42′ on the slot 41′ of the stop section 4′ are forced to expand outward respectively to engage the stop stocks 21′ on the slide track 2′, so the extended rod 1′ is stopped thereof. If the pull board 5′ is pull outward, the extension section 51′ will leave the V slot 41, the stop sections 42′ of the stop section 4′ will shrink inward and the stop stock 21′ of the slide track 2′ is free from both sides of the stop sections 42′ of the stop sections 4′, the extended rod 1′ is released from the slide track 2. However, even though the stop section 4′ is separated from the pull board 5, the different swing direction still exists on the left and right side of the drawer. For the production alone, the cost is high and the assembly is time consuming, not good for competition.

Due to the fact that the demand for the extended rod of the slide mechanism for the multiple drawer slide tracks is ever increasing and the inconvenience caused by the upswing and downswing in disengaging the control stop of the slide mechanism of prior art, a great efforts have devoted to the improvement and now come up an improved control stop structure of the slide mechanism.

SUMMARY OF THE INVENTION

The unique technology applied in this invention is that the control stop is an integrally formed extrusion with a swing section riveted on the extended rod. One end of the swing section extends to form a cut section for engaging the stop stock of the slide track and the other end extends to form a push-pull board. When the push-pull board is pushed or pulled, the swing section will pivot upward to disengage the cut section from the stop stock, permitting the extended rod to fall off the slide track. This improved control stop of the slide mechanism, regardless whether being mounted on the left or right side of the drawer, is very convenient for the operation to disassemble the drawer. In addition, it is easy to fabricate and assemble, great beneficiary to the manufacturers. This is the main object of this invention.

DETAILED DESCRIPTION OF THE INVENTION

Please refer to FIG. 6, the control stop of the extended rod mainly comprises a control stop 11 mounted on the extended rod I and the stop stock 21 mounted on the front end of the slide track 2.

As shown in FIGS. 7 through 10, the control stop 11 is an integrally formed extrusion with a swing section 111 riveted on the extended rod 1. One end of the swing section 111 forms a cut section 112 for engaging the stop stock 21 of the slide track 2. The other end of he swing 111 forms a push-pull board 113 which starts from the fine bent and extends outward to become a broad board.

As shown in FIG. 11, when the push-pull board 113 is pushed, the swing section 111 will swing up to disengage the cut section 112 from the stop section 211 of the stock 21 and let go the extended rod 1 off the slide track 2.

As shown in FIG. 12, a part of the push-pull board 113 can extend downward through the join of swing section which become a broad board, and mounted a right angle slant 114, here the push-pull board 113 works as a pull board as shown in FIG. 13. Once the push-pull board 113 is pulled, the slant 114 will press on the swing section 111 and force the swing section 111 to make a turning action in the manner that the cut section acts 112 as a leverage to disengage the stop section 211 of the stop stock 21, letting go the extended rod 1 off the slide track 2.

It is well learned from the above statement that the improved control stop structure of he slide mechanism where it requires only pushing or pulling the control stop 11 to disengage the extended rod 1 from the slide track 2. It offers a convenience for the operation to disassemble and easy for the manufacturer to fabricate, gaining huge benefit and progressiveness.
