Description

Sliding lifting structure

The creation is a sliding lifting structure that utilizes a sliding displacement traction lifting structure to increase the original seating space of the sofa.

According to the universal sofa, it has visual effects, modern fashion, comfortable ride and ergonomic design. Its main components are backrest, wrist rest, seat cushion and chair legs. Most of them are made up in a fixed way. Therefore, if used When you want to take a short break on the sofa, you often can't rest in the most comfortable position, and feel uncomfortable and inconvenient.

The main purpose of the present invention is to provide a sliding lifting structure, which can increase the original seating space of the sofa by using the sliding displacement traction lifting structure, and provide the user with a comfortable and relaxed sitting posture or lying on the sofa.

In order to achieve the above purposes and effects, the creation of the sliding lifting structure mainly includes: a seat cushion base having two pulley seats and fixed to the bottom of the sofa; and a lifting structure having a lifting cushion at one end and a seat base at the other end; a seat cushion skeleton having a slide rail in the seat frame and slidingly engaging with a pulley seat of the seat base; a chain having one end connected to the lifting structure, the other end connecting the cushion frame to achieve the linkage; and a positioning rocker arm having a spring, and Fixed to the side of the seat base; and a pull cord, combined with the positioning rocker arm, controls the sliding lift structure; thereby, when the user pulls the drawstring, The positioning rocker arm interlocks the spring, so that the inner slide rail of the cushion frame can be displaced by a force, and the traction chain drives the lifting structure to raise the lifting structure to increase the original seating space of the sofa.

Please refer to Figure 1 to Figure 4D for a partial exploded view, a partial cross-sectional view and an actuation diagram of the creation. The creation slide lifting structure 10 mainly comprises: a seat cushion base 20, a lifting structure 30, a chain 40, a cushion frame 50, a positioning rocker arm 60 and a pull cord 70.

Referring to FIG. 1 to FIG. 2B, the seat base 20 is fixed to the bottom of the sofa, and the pulley seat 21 is mounted on both sides thereof, and the lifting structure 30 is installed inside. The lifting structure 30 is composed of two lifting link sets 31, a supporting beam 32 and a lifting cushion 33. One end of the lifting link set 31 is mounted on the cushion base 20, and the other end is combined with the lifting cushion 33; the supporting beam 32 is Set in the two lifting link sets 31 And connect with it. The inner side of the cushion frame 50 is provided with a slide rail 51, and a plurality of positioning holes 52 are provided; the cushion frame 50 can be combined with a seat cushion 13. The slide rail 51 is slidably engaged with the pulley base 21 of the seat cushion base 20 to allow the cushion frame 50 to slide on the cushion base 20. A chain 40 has one end connected to the support beam 32 of the lifting structure 30, and the other end is fixed to the cushion frame 50 to interlock the cushion frame 50 with the lifting structure 30. The positioning rocker arm 60 is disposed on the side of the seat base 20 and is provided with a spring 61; the positioning rocker arm 60 cooperates with the positioning hole 52 of the cushion frame 50 to adjust the position of the fixed lifting structure 30 and the cushion frame 50; One end of the 61 is fixed to the positioning rocker arm 60, and the other end is fixed to the same side of the seat base 20 and the positioning rocker arm 60. The drawstring 70 is coupled to the positioning rocker arm 60 at one end and the seat cushion 13 at the other end to control the slide lift structure 10.

Referring to FIG. 2A to FIG. 3B, when the user pulls the pull cord 70 to pull the positioning rocker arm 60, the positioning rocker arm 60 is separated from the positioning hole 52, because the slide rail 51 of the cushion frame 50 and the pulley base of the cushion base 20 The 21 series sliding fit allows the cushion frame 50 to be displaced to the right on the cushion base 20 (in the embodiment, the left and right direction is illustrated, but the device is not limited to only move left and right). At this time, the cushion frame 50 will The support beam 32 of the lifting structure 30 is driven by the chain 40 by the displacement, so that the lifting link group 31 of the lifting structure 30 is actuated to drive the upper lifting cushion 33 to rise; when the user releases the pulling rope 70, the positioning rocker arm 60 is subjected to The spring force of the spring 61 affects the positioning rocker arm 60 and cooperates with the positioning hole 51 of the cushion frame 50 to fix the position of the cushion frame 50 and the lifting structure 30, and the lifting structure 30 is raised to the top end, so that the lifting cushion 33 reaches The appropriate height, by this, can increase the original seating space of the sofa, allowing the user to lie on the sofa in a more comfortable posture.

Referring to FIG. 4A to FIG. 4D, when the user rides on the sofa, the pull cord 70 is pulled to pull the positioning rocker arm 60, and the positioning rocker arm 60 is separated from the positioning hole 52, so that the cushion frame 50 can be seated on the cushion. Sliding displacement on the base 20; FIG. 4B shows the cushion frame 50 and the seat cushion 13 forward In the moving state, the positioning rocker arm 60 and the positioning hole 52 are separated from each other; when the cushion frame 50 and the seat cushion 13 are displaced forward to a predetermined position, the chain 40 drives the support beam 32 of the lifting structure 30 to lift the lifting structure 30. The rod set 31 is actuated to drive the upper lifting seat cushion 33 to rise, as shown in FIG. 4C; when the seat cushion frame 50 is slidably displaced to the relative position of the plurality of positioning holes 52 to which the positioning rocker arm 60 is engaged, the lifting structure 30 is raised to the top end. The lifting cushion 33 is brought to an appropriate height, and by the positioning of the rocker arm 60 and the plurality of positioning holes 52, the seat cushion 13 can be moved and the lifting cushion 33 can be lifted and lowered, as shown in FIG. 4D, whereby the user It can be adjusted freely to increase the original seating space of the sofa.

The above is a detailed description and drawing of the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto; it is not found in the publication or public use, and is suitable for the application requirements of the patent, and is filed according to law.
