Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of seats, and in particular relates to a seat with a shielding structure at the rotational junction of a seat cushion and a leg rest. Background Art
[0002] At present, some high-end sofas or seats are provided with retractable and foldable leg rests, which bring great comfort to people. However, after the leg rest is rotated, extended and unfolded, a large triangular gap is formed at the side wall adjacent to the seat cushion and the leg rest. Not only can the internal transmission structure be seen, but external objects may accidentally enter the triangular gap through the triangular gap, which may easily cause adverse consequences such as the mechanism getting stuck. The triangular gap also gives people an uncomfortable appearance. Summary of the Invention
[0003] The utility model aims to provide a chair with a shielding structure at the rotational joint of the seat cushion and the leg rest, which has good appearance and can shield the triangular gap between the seat cushion and the leg rest.
[0004] The purpose of this utility model is to solve:
[0005] A seat with a shielding structure at the rotatable joint between a seat cushion and a leg rest comprises a seat cushion and a leg rest, wherein a seat cushion cover is mounted on the seat cushion, and a leg rest cover is mounted on the leg rest, the seat cushion cover is connected to the upper surface of the leg rest cover, and shielding cloth is connected to the side opposite to the seat cushion cover for shielding the side gap between the leg rest cover and the seat cushion cover when the leg rest is unfolded, and the shielding cloth can automatically retract into the space in the gap between the seat cushion and the leg rest when the leg rest is folded.
[0006] As a further optimization of the above technical solution, the shielding cloth is formed by butting and sewing two triangular or fan-shaped cloth pieces, and the two side edges of the shielding cloth are respectively sewn and connected to the side edges of the leg support cover and the seat cushion cover.
[0007] As a further optimization of the above technical solution, a PP plastic support sheet is sewn or glued on the inner surface of at least one of the two triangular or fan-shaped cloth pieces.
[0008] As a further optimization of the above technical solution, the shape of the PP plastic support sheet is a shape that is proportionally reduced to the shape of the cloth piece.
[0009] As a further optimization of the above technical solution, the leg support cover, seat cushion cover and shielding cloth are made of cotton cloth, fiber cloth, leather or artificial leather.
[0010] As a further optimization of the above technical solution, an elastic cloth or an elastomer is centrally connected to the inner surface of the covering cloth, and a fastener is provided at the outer end of the elastic cloth or the elastomer. The fastener is snapped onto the bracket or telescopic structure at the bottom of the seat cushion or the leg rest, so that the covering cloth can automatically retract into the space in the gap between the seat cushion and the leg rest after the leg rest is folded.
[0011] The outstanding advantages of the utility model compared with the prior art are:
[0012] 1. The utility model uses a blocking cloth to cover the gap between the leg support cover and the seat cushion cover after the leg support is unfolded, so as to make the product look and feel better and better prevent foreign objects from entering between the leg support cover and the seat cushion cover.
[0013] 2. The utility model utilizes the PP plastic support sheet to make the two cloth pieces constituting the shielding cloth more neat and consistent in their retraction and extension, and will not cause partial retraction or incomplete or incomplete retraction or extension.
[0014] 3. The utility model utilizes elastic cloth or elastomer as the elastic reset component, which has a simple structure, is lightweight, has low production cost, and is easy to install and replace.
[0015] 4. The utility model is suitable for the promotion and use of seats with retractable leg rests. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 It is a three-dimensional schematic diagram of the leg support of the present invention after being folded.
[0017] Figure 2 It is a three-dimensional schematic diagram of the leg support of the utility model after being unfolded.
[0018] Figure 3 It is a schematic diagram of the connection relationship at the inner surface of the shielding cloth of the present invention. DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings. Figure 1-Figure 3 :
[0020] A seat with a shielding structure at the rotatable joint between a seat cushion and a leg rest comprises a seat cushion and a leg rest, wherein the seat cushion is fitted with a seat cushion cover 10, and the leg rest is fitted with a leg rest cover 20, the seat cushion cover 10 is connected to the upper surface of the leg rest cover 20, and the side opposite to the leg rest cover 20 is connected to a shielding cloth for covering the side gap between the leg rest cover 20 and the seat cushion cover 10 when the leg rest is unfolded, and the shielding cloth can automatically retract into the space in the gap between the seat cushion and the leg rest when the leg rest is folded.
[0021] As a further optimization of the above technical solution, the shielding cloth is formed by butting and sewing two triangular or fan-shaped cloth pieces 30 together, and the two side edges 32 and 31 of the shielding cloth are sewn to the side edges 21 of the leg support cover 20 and the side edges 11 of the seat cushion cover 10 respectively.
[0022] As a further optimization of the above technical solution, a PP plastic support sheet 35 is sewn or glued on the inner surface of at least one of the two triangular or fan-shaped cloth pieces 30 .
[0023] As a further optimization of the above technical solution, the shape of the PP plastic support piece 35 is a shape proportionally reduced from the shape of the cloth piece 30, so as to facilitate the smooth retraction and extension of the leg support.
[0024] As a further optimization of the above technical solution, the leg support cover 20, the seat cushion cover 10, and the shielding cloth are made of cotton cloth, fiber cloth, leather, or artificial leather.
[0025] As a further optimization of the above technical solution, an elastic cloth 33 or an elastomer is centrally connected to the inner surface of the shielding cloth, and a fastener 34 is provided at the outer end of the elastic cloth 33 or the elastomer, and the fastener 34 is clamped on the bracket 40 or the telescopic structure at the bottom of the seat cushion or the leg rest, so that the shielding cloth can automatically retract into the space in the gap between the seat cushion and the leg rest after the leg rest is folded. After the leg rest is unfolded, the shielding cloth covers the triangular gap formed by the unfolding of the seat cushion and the leg rest, which can not only cover the internal transmission structure, but also prevent external objects from entering the triangular gap through the triangular gap, causing adverse consequences such as mechanism jamming, and gives people a wonderful visual experience.
