Description

TECHNICAL FIELD

[0001] The utility model relates to daily necessities technical field especially, it relates to a foldable beach recliner. BACKGROUND

[0002] As an outdoor leisure tool, the beach recliner has become a common facility in beach, swimming pool and other scenes due to its portability and comfort. To meet the transportation and storage needs, the existing beach chairs generally adopt foldable design, and the folding and contraction of the chair back, seat and support frame are realized through the hinged structure, so as to reduce the volume and facilitate carrying. Such folding structure usually relies on a connecting rod mechanism to realize stable support in the unfolded state, and forms a rigid configuration after unfolding to meet the load bearing requirement.

[0003] The unfolding and locking of the existing beach recliner mainly adopts a connecting rod over-limiting structure, the principle of which is to form a rotatable connection through the hinging of two connecting rods, and to make the axes of the two connecting rods approach or reach the collinear state when unfolded. When the hinging axis of the connecting rod assembly is collinear with the chair frame fulcrum, the connecting rod system is in the theoretical "dead point" position, at which time the force transmission path of the chair frame forms a self-locking, which can theoretically avoid accidental folding. For example, the portable foldable beach recliner with the publication number CN208274412U adopts such a connecting rod locking scheme, and the unfolded state is fixed through the straight alignment of the chair back connecting rod and the base connecting rod.

[0004] However, the above-mentioned connecting rod locking structure has the following significant defects: when the two connecting rods are completely unfolded to the collinear state, the hinging point is at the mechanical dead point position, and the folding operation needs to exert an external force perpendicular to the connecting rod axis to break through the dead point. Since there is no auxiliary unlocking design for the hinging point, the user can only realize folding by knocking or twisting the connecting rod connection with great force, which has the following problems: when manually rotating the hinging point, the user's fingers cannot effectively exert force, and the smooth surface of the connecting rod makes it difficult to hold; when kicking the hinging point with the feet, the vamp or contact object is easy to be clamped into the V-shaped angle area between the two connecting rods, which has the risk of injury or damage to the object; high-frequency violent unlocking can easily cause the deformation of the hinging shaft, reducing the structural reliability.
