Pressing rebound opening and closing optimization structure for furniture

Abstract

The invention relates to a pressing rebound opening and closing optimization structure for furniture, which comprises a moving sliding rail and a fixed sliding rail.A movable member is arranged on themoving sliding rail, a pressing rebounding device is arranged on the fixed sliding rail, the pressing rebound device comprises a rebounding bracket, a pushing component, a sliding component, and a lever assembly, the pushingcomponent is positioned and / or slid on the rebounding bracket, a pressing elastic member is arrangedbetween the pushing component and the rebounding bracket, the sliding component is slidably arranged on the pushing component, and the lever assembly is coupled with the pushing component and / or the sliding component, two steering wheels are arranged on the rebounding bracket, and the pressing elastic member isarranged on the two steering wheels in a winding mode; the moving sliding railpresses and actuates the pushing component and / or the sliding component to slide on the rebounding bracket in a rebounding mode by pressing the elastic member at least during opening so that the moving sliding rail is slidably opened on the fixed sliding rail in a pressing rebound mode; the movable member acts on the lever assembly when the moving sliding rail is closed or opened for at least one stroke, and the pushing component and / or the sliding component is driven to slide onthe rebounding bracket in a reset mode through the lever assembly and positioned to the initial position of a terminal.

Description

technical field [0001] The invention relates to an optimized structure for pressing and rebounding opening and closing of furniture. Background technique [0002] Chinese Patent Document No. CN107411385A disclosed a furniture automatic reset press rebound mechanism on April 14, 2017. It includes furniture movable parts, furniture fixed parts, connecting elements and fixed brackets. On the fixed part of the furniture, a pressing rebound device, a telescopic reset device and at least two rotating wheels are provided on the fixed bracket. The pushing element and the telescopic element slide on the fixed bracket respectively, and at least two rotating wheels are set relatively independently and respectively rotate on the fixed bracket. At least two rotating wheels cooperate with each other when rotating to a certain position. Drive connection, the other rotating wheel is driven and connected with the push element; the push element is provided with a swing element, and the fixed...

AI Technical Summary

Problems solved by technology

This structure must overcome the elasticity of the third elastic element when it is pressed to open, so that the push element can slide and open along the track of the heart-shaped chute. Due to the high elasticity of the third elastic element, the user needs to apply the same force when pressing. As a result, the user must use a large force to press and open the furniture. At the same time, when both opening and closing require simultaneous force, the user must also use a large force to reset and press the rebound mechanism to close the furniture, which affects the user experience. At the same time, it is inconvenient for users to use. At the same time, due to the limited volume of the fixed bracket, the length of the elastic element cannot be increased, otherwise it will affect the placement of other components. Therefore, the elastic force produced by the elastic element is not effective and cannot meet the needs of users.
