Description

  The present invention relates to a frame structure for a leisure chair, and more particularly, to a frame structure for a leisure chair that can be folded easily by enhancing the strength of a handrail.

  Chairs are indispensable tools for daily life, and leisure chairs are used to support the lives of modern people and relax the body. However, leisure chairs are not usually necessary in daily life, so in the limited space of modern cities, when you do not use the leisure chair, you can fold it down to reduce its volume and save your living space There is a need to.

  Generally, the folding of a leisure chair has its main problem in the handrail part, and the two handrail parts are connected to the front leg bars of the left and right frames, respectively, and the connectivity and linkage by the structure of the front and rear left and right frames of the leisure chair Therefore, when folding a leisure chair, the prior art mainly causes the end portion connected to the front leg bar of the handrail to be removed, so that the handrail does not disturb the folding in the front-rear direction. However, removing the handrail is a cumbersome operation, and when it is desired to use the leisure chair at a later date, the handrail must be attached again, which is troublesome again. For this reason, it is necessary to improve the structure of the leisure chair in order to eliminate the removal of the handrail.

  In view of this, Taiwan Patent Publication No. 538728 discloses a handrail structure for a foldable leisure chair, and the leisure chair 5 mainly has one or more interrupted portions on each handrail 51. It is provided and connected by a joint structure 52, thereby forming two or more handrails 51A, 51B, and the leisure chair can be expanded or folded to be expanded or stored. It is said.

  However, as can be seen from the figure, the handrail 51 of the previous plan is basically in a state where the bottom portion is floating in the air just by fixing both ends, so that the strength to receive the weight of the human body is high. In general, this type of leisure chair tends to be deficient, and since the seat cushion 53 is installed by connecting four corners and four square bars, it is in a “point connection” state and is inadvertently applied. Rupture tends to occur when force is applied.

  The main object of the present invention is to provide a frame structure of a leisure chair that is excellent in strength and can provide a “line coupling” strength to a seat cushion with a lateral reinforcing bar.

  The frame structure of the leisure chair according to the present invention includes a front bar and a rear bar on each of two corresponding left and right sides, a cross frame is provided between the front bar and the rear bar, and a handrail is disposed above the cross frame. Installed, the handrail is assembled and connected with a first folding joint, and the present invention is particularly provided with a lateral reinforcement bar between the cross frame and the handrail, respectively, and the lateral reinforcement bar is a second folding joint. The second bent joint and the cross frame are installed at the lower edge of the handrail, and the vertical support bar is installed.

  The present invention further provides a left second bending joint so that the lateral reinforcing bar can be bent corresponding to the first bending joint of the handrail when folded.

  In addition, the present invention further folds the frame of the leisure chair in the front-rear direction so that the front bar and rear bar are aligned with the vertical support bar and the ground so that the frame of the leisure chair can be conveniently erected. The bar and rear bar are designed in the form of a telescopic pipe, and when the front bar and the left rear bar are pushed inward, the left vertical support bar is configured to match the length of the front bar and the rear bar depending on the form of the telescopic pipe.
