Description
Technical Field
[0001] The utility model belongs to the technical field of machinery and relates to a sofa with an adjustable headrest. Background Art
[0002] The sofa is a common piece of furniture, a cushioned, multi-seater chair with armrests. Originating in the West and later introduced to Asia, it has become a focal point in Western and modern home design. Made of wood or steel and lined with cotton or other foam materials, the chair is generally comfortable. In winter, people enjoy leaning against the soft, warm headrests of a sofa; in summer, they prefer the coolness of bamboo mats.
[0003] The headrests of single-seater sofas for home use are mostly fixed to the backrests, and the angle cannot be adjusted. In addition, the headrests of ordinary sofas are made of a single material and cannot be used in both winter and summer. They have certain limitations in use and poor applicability. Utility Model Content
[0004] The purpose of the utility model is to provide a sofa with an adjustable headrest and strong applicability in view of the above problems existing in the prior art.
[0005] The purpose of this utility model can be achieved through the following technical solutions:
[0006] A sofa with an adjustable headrest is characterized in that it comprises a sofa seat, a double-sided headrest and a positioning piece, wherein sofa armrests are fixedly installed on both sides of the sofa seat, the rear side of the sofa seat is fixedly connected to the sofa backrest, one side of the upper part of the sofa backrest is fixedly connected to a hinge seat 1, and the other side is fixedly connected to a hinge seat 2, one side of the double-sided headrest is fixedly connected to a rotating seat, and the other side of the double-sided headrest is fixedly connected to a guide seat, the rotating seat and the guide seat are opposite to each other, the rotating seat is hinged on the hinge seat 1, and the guide seat is hinged on the hinge seat 2, the positioning piece is located between the hinge seat 1 and the rotating seat, and the positioning piece can adjust the circumferential position of the double-sided headrest and perform positioning; one side of the double-sided headrest is provided with a heat preservation surface that can be used in winter, and the other side is provided with a heat dissipation surface that can be used in summer.
[0007] The utility model creatively provides a sofa seat and a positioning piece. The rotating seat and the guide seat are both circular plates. The rotating seat is hinged to the hinge seat one with the center of the end face as the hinge point, and the guide seat is hinged to the hinge seat two with the center of the end face as the hinge point. The rotating seat can adjust the circumferential position of the double-sided headrest and position it through the positioning piece, thereby making it convenient for the operator to adjust the angle of the headrest and facilitating use.
[0008] The double-sided headrest in the utility model can adjust the angle, and since the headrest is double-sided, one side is a heat-insulating side and the other side is a heat-dissipating side, it can be used in both winter and summer, thereby improving the applicability of the device.
[0009] In the above-mentioned sofa with an adjustable headrest, sofa legs are respectively fixedly connected to the four corners of the bottom of the sofa seat.
[0010] The setting of the sofa legs makes the sofa structure more stable.
[0011] In the above-mentioned sofa with an adjustable headrest, the sofa armrest is provided with a recessed placement opening.
[0012] The storage opening is used to place remote controls, books, newspapers and other miscellaneous items.
[0013] In the above-mentioned sofa with an adjustable headrest, a connecting plate is fixedly connected to the outer side of one of the sofa armrests, a round rod is hinged on the connecting plate, and a placement plate is threadedly connected to the top of the round rod.
[0014] The rotation of the round rod can drive the placement plate to rotate, and the placement plate can be used to place tea cups, snacks and other miscellaneous items. The placement plate is connected to the top of the round rod through a thread to achieve detachable installation.
[0015] In the above-mentioned sofa with adjustable headrest, the side of the hinged seat 1 has several concave semicircular grooves, which are semicircular in shape; the several semicircular grooves are evenly distributed circumferentially with the hinge point between the hinged seat 1 and the rotating seat as the center.
[0016] The arrangement of the plurality of semicircular grooves enables the double-sided headrest to be circumferentially rotated and positioned at different positions with the hinge point as the center through the positioning piece.
[0017] In the above-mentioned sofa with an adjustable headrest, the positioning member includes a groove, a spring and a ball. The side of the rotating seat adjacent to the hinged seat has a hollow groove. The spring and the ball are connected to the inside of the groove. The two ends of the spring are respectively connected to the groove and the ball. Under the elastic force of the spring, the ball has a tendency to rest against the semicircular groove.
[0018] Under normal conditions, the concave semicircular shape of the semicircular groove enables the ball to be more closely attached to the semicircular groove. Under the action of external force, the ball can leave the semicircular groove and slide along the side of the hinge seat until it rests in the next semicircular groove under the elastic force of the spring, thereby achieving the positioning of the double-sided headrest and the change of the circumferential position.
[0019] In the above-mentioned sofa with adjustable headrest, the double-sided headrest includes a partition, a flannel pillow is provided on one side of the partition, and a bamboo mat pillow is provided on the other side of the partition, and the flannel pillow and the bamboo mat pillow are fixedly connected through the partition.
[0020] Both flannel pillows and bamboo mat pillows are existing technologies. The surface of the flannel pillow is composed of flannel, and the fabric is filled with cotton-like fillings to form a heat-insulating surface that can be used in winter; the surface of the bamboo mat pillow is composed of woven bamboo rattan to form a heat-dissipating surface that can be used in summer.
[0021] Compared with the prior art, the sofa with adjustable headrest is creatively provided with a sofa seat and a positioning piece. The rotating seat and the guide seat are both circular plates. The rotating seat is hinged to the hinge seat one with the center of the end face as the hinge point, and the guide seat is hinged to the hinge seat two with the center of the end face as the hinge point. The rotating seat can adjust the circumferential position of the double-sided headrest and position it through the positioning piece. Under normal conditions, the concave semicircular setting of the semicircular groove enables the ball to be more closely attached to the semicircular groove. Under the action of external force, the ball can leave the semicircular groove and slide along the side of the hinge seat one until it rests on the next semicircular groove under the elastic force of the spring, thereby realizing the positioning of the double-sided headrest and the change of the circumferential position, making it convenient for the operator to adjust the angle of the headrest.
[0022] At the same time, in summer, the double-sided headrest can be rotated to the heat dissipation side with a bamboo mat pillow, and in winter, the double-sided headrest can be rotated to the heat preservation side with a velvet pillow, thereby achieving dual use in winter and summer and improving the applicability of the device.
