Novel handrail structure

Technical Field

The utility model relates to the field of furniture, in particular to a novel handrail structure.

Background

In order to improve the comfort of the seat, the existing seat is generally provided with armrests so as to support the arms of a user and improve the sitting comfort. Generally, existing armrests of seats are mainly divided into a fixed armrest and a movable armrest, the fixed armrest is fixedly arranged on the seat to provide an arm supporting function, and the movable armrest can adjust the position and the posture of the armrest relative to the seat, so that the arms of a human body can be supported under different human body postures.

However, the existing movable armrests are relatively dead-plate old sleeves in movement mode, the conventional movable armrests are generally provided with bearing parts for bearing arms of human bodies and connecting parts for connecting seats, the connecting parts are vertically arranged, the bearing parts are horizontally or slightly obliquely arranged, the connecting points of the bearing parts and the connecting parts of the conventional movable armrests are generally positioned in the middle of the bearing parts, the bearing parts can rotate and can lift, but the shape of the armrests is always T-shaped; because the seat is fixed, the connecting part and the seat are generally static relatively, and the bearing part can only rotate on the connecting part and can not change the relative position of the connecting part and the bearing part, the arm placing position of a user is limited by the position of the bearing part relative to the connecting part, so that the armrest can not adapt to more human postures.

in a normal state, the movable end faces to the rear, and the movable end selectively rotates in the horizontal direction;

in the active state, the active end faces forward, and the active end selectively swings in the horizontal direction and the vertical direction.

In a conventional state, the structure takes a conventional armrest posture and can only rotate left and right; however, after the hand-operated member is switched to the movable state, the hand-operated member is similar to a support arm (arm or mechanical arm) and can rotate in the horizontal direction and the vertical direction, so that the hand-operated member is more flexible; the joint end is connected with the support piece and is relatively static with the support piece, and when the movable end moves, the whole armrest piece also rotates, so that the relative position of the armrest piece and the support piece and the shape formed by the armrest piece and the support piece are changed, and the position where the arm of a user can rest is more random, so that the armrest piece can adapt to more human postures.

Preferably, the support piece is arranged vertically, the upper end of the support piece extends forwards to form an extension arm, and the joint end of the manual piece is connected with the end part of the extension arm; when the movable end faces backward, the manual piece and the supporting piece are in a T shape; when the movable end faces forward, the manual piece and the supporting piece are L-shaped. Because the end of the manual part is connected with the supporting part, the shape of the structure can be changed when the manual part rotates, and the multiple shapes are more suitable for supporting arms under different human postures.

Preferably, the manual member is in a long strip shape, and the movable end and the joint end are two ends of the manual member in the length direction. Because the movable end and the joint end are two end parts of the manual part, when the movable end moves after the joint end is connected with the support part, the whole manual part moves along with the movable end, and the relative position of the manual part and the support part and the shape formed by the two parts are changed.

Preferably, friction elements are provided between the joint element and the support element and/or between the joint element and the hand-operated element, the friction elements being configured to increase friction damping.

Preferably, the friction member is soft rubber. The soft rubber friction piece is more comfortable than the modes such as gear teeth, tooth slot joint limit and the like, the rotation feeling is better and smoother, the adjustment of the manual piece is realized by single-hand operation, and the switch is not needed.

Preferably, a state locking member is further provided between the manual member and the support member, the state locking member being configured to prevent rotation of the manual member in the vertical direction in a normal state. In the normal state, the state locking member can prevent the rotation of the manual member in the vertical direction and enable the manual member to rotate only in the horizontal direction.

Preferably, the state locking piece is a limiting table protruding downwards from the manual piece, and in a conventional state, the limiting table is abutted against the supporting piece; when switching from the normal state to the active state, the limit table horizontally rotates away from the support.

Preferably, the support piece comprises a body which is vertically arranged and an extension arm which is horizontally arranged, wherein the extension arm is arranged at the upper end part of the body and extends forwards beyond the body, and the extension arm and the body are L-shaped; the limiting platform is abutted against the extension arm in a conventional state. The switching process only needs to rotate the manual part to enable the state locking part to be separated from the supporting part, and is simple and convenient.

The design starting point, the idea and the beneficial effects of the utility model adopting the technical scheme are as follows:

in a conventional state, the structure takes a conventional armrest posture and can only rotate left and right; however, after the hand-operated member is switched to the movable state, the hand-operated member is similar to a support arm (arm or mechanical arm) and can rotate in the horizontal direction and the vertical direction, so that the hand-operated member is more flexible; the joint end is connected with the support piece and is relatively static with the support piece, and when the movable end moves, the whole armrest piece also rotates, so that the relative position of the armrest piece and the support piece and the shape formed by the armrest piece and the support piece are changed, and the position where the arm of a user can rest is more random, so that the armrest piece can adapt to more human postures.

The soft rubber friction piece is more comfortable than the modes such as gear teeth, tooth slot joint limit and the like, the rotation feeling is better and smoother, the adjustment of the manual piece is realized by single-hand operation, and the switch is not needed.
