The present invention relates to a recliner, in particular to a foldable recliner.
A recliner is a sitting tool commonly used in daily life and generally includes a backrest, a seat surface and armrests. In order to pursue comfort, people will lean the back on the backrest of the recliner while sitting on the recliner. Due to different heights of people, taller people often find that the backrest of the recliner is not high enough when using the recliner, such that the head will be suspended on the backrest when using the recliner, and comfort and user experience will be greatly reduced. In addition, a user can adjust an inclination angle of the backrest of the recliner from a sitting posture to a lying posture. However, when the inclination angle of the backrest is increased, a suspended portion of the backrest is increased, thereby reducing the stability of the recliner and leading to falling and other situations of the user who uses the recliner to take a rest.
Technical problems to be solved by the present invention are as follows. In order to solve the problems that a backrest of a recliner is not high enough and the stability of the recliner is reduced when an angle of the backrest is increased, the present invention provides a foldable recliner to solve the above problems.
A technical solution adopted by the present invention to solve the technical problems is: a foldable recliner, comprising a supporting assembly and a backrest, wherein the backrest is hinged to the supporting assembly through first rotating shafts, and the backrest can be rotated between a sitting posture state and a lying posture state relative to the supporting assembly; further comprising a ground supporting component and unfolding components, wherein the unfolding components are fixedly connected to the backrest, and first guide blind holes and second guide blind holes are formed in the unfolding components; when the backrest is in the sitting posture state, the ground supporting component is inserted into the first guide blind holes, and a height of the ground supporting component is greater than that of the backrest; and when the backrest is in the lying posture state, the ground supporting component is inserted into the second guide blind holes, such that the ground supporting component is in contact with the ground to support the backrest.
As a preference, the backrest comprises backrest rods, two first guide grooves that are in mirror symmetry are formed on two side surfaces of the unfolding components along an extension direction of the first guide blind holes, two second guide grooves that are in mirror symmetry are formed on two side surfaces of the unfolding components along an extension direction of the second guide blind holes, the first guide grooves and the second guide grooves are distributed in an intersected mode, and terminal ends of the ground supporting component are connected to the first guide grooves and the second guide grooves that are distributed in an intersected mode through connecting pins, and can move along a guide direction of the first guide grooves or the second guide grooves.
As a preference, the supporting assembly comprises first supporting legs, second supporting legs, a supporting frame and a reinforcing beam, upper ends of the first supporting legs are pivotally connected to upper ends of the second supporting legs, first hinge members are hinged to the second supporting legs, U-shaped connecting sheets are fixed on a rear end of the supporting frame, end portions of the backrest rods are embedded into opening portions of the U-shaped connecting sheets and hinged to the U-shaped connecting sheets and the first hinge members through the first rotating shafts, the supporting frame is pivotally connected to the first supporting legs, and two ends of the reinforcing beam are fixedly connected to the rear end of the supporting frame.
As a preference, the foldable recliner further comprises armrests, wherein rear ends of the armrests are hinged to the backrest rods, lower ends of the armrests are provided with two hanging portions, guide grooves are formed on the hanging portions, groove walls of the guide grooves are provided with a plurality of hooks, pivot joints of the upper ends of the first supporting legs and the upper ends of the second supporting legs are fixedly connected with connecting shafts, two ends of the connecting shafts are sleeved in the two guide grooves, respectively, and by moving the connecting shafts in the guide grooves, the different hooks are hung on the connecting shafts.
As a preference, the supporting assembly comprises first supporting legs, second supporting legs, a supporting frame and a reinforcing beam, upper ends of the first supporting legs are pivotally connected to upper ends of the second supporting legs, first hinge members are hinged to the second supporting legs, U-shaped connecting sheets are fixed on the supporting frame, the first hinge members are hinged to the supporting frame through the first rotating shafts, lower portions of the backrest rods are embedded into opening portions of the U-shaped connecting sheets and hinged to the U-shaped connecting sheets through second rotating shafts, the supporting frame is hinged to the first supporting legs, and two ends of the reinforcing beam are connected to the first supporting legs.
As a preference, the foldable recliner further comprises armrests, wherein rear ends of the armrests are hinged to the backrest rods, lower ends of the armrests are provided with hanging portions, guide grooves are formed on the hanging portions, groove walls of the guide grooves are provided with a plurality of hooks, gaps are remained between the first supporting legs and the second supporting legs when the first supporting legs are pivotally connected to the second supporting legs, pivot shafts between the first supporting legs and the second supporting legs pass through the guide grooves, and by moving the pivot shafts in the guide grooves, the different hooks are hung on the pivot shafts.
Beneficial effects of the present invention are as follows. When the ground supporting component of the foldable recliner is inserted into the first guide blind holes, the ground supporting component is equivalent to an extension of the backrest at this time, and the height of the backrest is increased. When the ground supporting component is inserted into the second guide blind holes, the backrest of the recliner is adjusted backward to be in the lying posture state at this time, and the ground supporting component can be supported on the ground, such that the recliner is more stable to use.
The present invention will be further explained below in conjunction with attached drawings and embodiments.
Reference numerals in the figures are as follows: 1, first rotating shaft; 2, armrest; 3, ground supporting component; 4, unfolding component; 5, connecting pin; 6, backrest rod; 9, first guide groove; 10, second guide groove; 11, first supporting leg; 12, second supporting leg; 13, supporting frame; 14, reinforcing beam; 15, first hinge member; 16, U-shaped connecting sheet; 17, second rotating shaft; 18, hanging portion; 19, protective cover; 20, hook; 21, connecting shaft.
