Description

Technical Field

[0001] The present application relates to the technical field of outdoor folding chairs, and in particular to a folding beach chair. Background Art

[0002] A folding chair is a portable chair, usually made of metal, plastic or wood, that can be easily folded up to save space. This type of chair is mainly used for outdoor activities, camping, picnics, beaches, etc., and can also be used as a household item.

[0003] The design of folding chairs is based on ergonomics and mechanical principles, aiming to provide a comfortable sitting posture and stable support. Currently, the seat surfaces of common folding chairs include plastic, aluminum alloy, and cloth. However, the seat surfaces made of plastic and aluminum alloy are fixed in shape and cannot provide wrapping support. Therefore, they are inferior to fabric in terms of comfort, and fabric is lighter in weight and easier for users to carry. Related prior arts such as Chinese patent application "Folding Chair", application number: CN202010436493.9; discloses a chair seat and a folding chair frame, the folding chair frame includes left and right chair frames arranged symmetrically on the left and right, the left and right chair frames both include a back rod unit, the folding chair frame also includes left and right folding mechanisms and lifting parts arranged symmetrically on the left and right, the left and right folding mechanisms both include an upper pull rod and a lower pull rod, the inner ends of the upper pull rods of the left and right folding mechanisms are respectively hinged to the two sides of the upper end of the lifting part, the outer ends of the upper pull rods of the left and right folding mechanisms are respectively hinged to the back rod units of the left and right chair frames, the inner ends of the lower pull rods of the left and right folding mechanisms are respectively hinged to the two sides of the lower end of the lifting part, the outer ends of the lower pull rods of the left and right folding mechanisms are respectively slidably connected to the back rod units of the left and right chair frames, and the up and down movement of the lifting part drives the left and right chair frames to be relatively close to each other in a folded state or relatively far away from each other in an unfolded state through the left and right folding mechanisms.

[0004] However, in order to improve the structural strength of the entire support frame, the above patent application adds cross-arranged frames on the backrest surface and the leg support surface. However, after the fabric of the folding chair is loosened, or the force applied by the user to the fabric causes the fabric to be significantly deformed, the user will clearly feel the frame, that is, the user's comfort is not high, and the structure deserves further improvement. Utility Model Content

[0005] The technical problem to be solved by the present application is to provide a folding beach chair, further optimizing the structure of the beach chair so that the chair has good structural strength while ensuring high comfort in use.

[0006] The technical solution adopted in the present application is: a folding beach chair, including a seat fabric, an armrest tube and a folding chair frame, the folding chair frame including a back frame, two brackets, and two support rods, the two support rods are arranged parallel to each other, the seat fabric is sleeved on the two support rods, the bracket is in a U-shaped structure, the two brackets are respectively hinged at the front end and the rear end of the two support rods, the back frame is in an inverted U-shaped structure and is vertically arranged above the two support rods, the back frame is hinged to the rear end of the support rod, and the two ends of the armrest tube are respectively hinged to the end of the back frame and the end of the bracket located on the front side.

[0007] Compared with the prior art, the advantages of the present application are that, firstly, the present application uses two support rods to stretch the seat fabric to form a seat for the user to sit. Secondly, the present application adopts a U-shaped structure when designing the bracket and back frame of the beach chair. The U-shaped structure makes the structure itself have good structural strength, and in the present application, the two brackets and the back frame both play the role of supporting the distance between the two support rods. The connection of multiple U-shaped structures makes the two support rods have good support for the seat fabric, thereby effectively improving the load-bearing capacity of the beach chair and improving the stability and reliability of the product when in use. Thirdly, the U-shaped structure makes the back frame and the two brackets themselves have good structural strength, and there is no need to add an additional cross skeleton structure to enhance its supporting performance. In addition, the U-shaped structure allows the user to lie on the present application without the back, buttocks, and legs touching the skeleton structure, so the user experience is good and the comfort of use is high.

[0008] In this application, for the convenience of description, the Figure 1 As a benchmark, the beach chair is in an open state.

[0009] In some embodiments of the present application, the two brackets are divided into a front bracket and a rear bracket, and the two ends of the rear bracket are connected to the rear end of the support rod through a connecting piece. The above structure allows the rear bracket of the beach chair to be flipped and folded relative to the support rod, and the rear bracket flips forward to fit the bottom of the support rod.

[0010] In some embodiments of the present application, the rear bracket is hinged to the connecting piece, and the rear end of the support rod is fixedly connected to the connecting piece. This structure makes the connection joint here more stable and reliable.

[0011] In some embodiments of the present application, the end of the front bracket is provided with two hinge points one which are staggered up and down, wherein the hinge point one located at the upper side is hinged to a connecting piece and is connected to the front end of the handrail tube through the connecting piece, and the hinge point one located at the lower side is hinged to the front end of the support rod.

[0012] When the front bracket is flipped and folded backward relative to the support rod, the upper end of the front bracket drives the handrail tube to move forward and downward, thereby driving the handrail tube to move downward until it fits with the top of the support rod.

[0013] In some embodiments of the present application, the back frame is provided with two hinge points 2 staggered up and down at the end thereof, wherein the hinge point 2 located at the upper end is hinged to the rear end of the support rod, and the hinge point 2 located at the lower end is hinged to a U-shaped frame, and is connected to the rear end of the handrail tube through the U-shaped frame. The above structure enables the back frame to be flipped and folded relative to the support rod, and prevents the back frame from being attached to the support rod when flipping, and the back frame flips forward to fit the bottom of the support rod.

[0014] In some embodiments of the present application, the rear end of the handrail tube passes through the middle of the U-shaped frame, the inner bottom surface of the U-shaped frame fits the handrail tube, the U-shaped frame is fixedly connected to the handrail tube, and the end of the back frame extends into the U-shaped frame and is hinged to the U-shaped frame. Similarly, the above structure makes the connection joint here more stable and reliable.

[0015] In some embodiments of the present application, the back frame is covered with a back cloth, which is stretched by the back frame, and the top of the back frame is bent backwards. The back of the user is supported by the back cloth, and the top of the back frame is bent backwards, which adapts to the human body structure and provides a good user experience. Secondly, the setting of the bending structure makes the structural strength of the back frame higher.

[0016] In some embodiments of the present application, the back frame and the armrest tube are covered with a hose pad to improve the comfort of the user in contact with the back frame and the armrest tube.

[0017] In some embodiments of the present application, the connecting member is a curved sheet-like structural member, a first end of the connecting member is connected to the support rod or the handrail tube, and a second end of the connecting member is hinged to the bracket.

[0018] In some embodiments of the present application, the second end of the connecting member includes a lower bottom surface, a first side surface and a second side surface, the first side surface is arranged closer to the support rod than the second side surface, and the first side surface and the lower bottom surface are transitioned by a curved surface. That is, the above structure enables the bracket in the folded state to be flipped outward relative to the support rod to the expanded state.

[0019] In some embodiments of the present application, the second side surface is a plane, the lower bottom surface of the connecting member is a plane, the bottom surface and the second side surface are connected at a right angle or an acute angle, and the inner bottom surface of the notch is a plane.

[0020] That is, the above-mentioned structural arrangement ensures that when the bracket is flipped over to the point where the inner bottom surface of the slot is parallel to the lower bottom surface of the connector, or in other words, in a contact state, the bracket reaches the limit position of the travel and is limited by the right angle or acute angle between the bottom surface and the second side surface, and the bracket cannot continue to flip outward.

[0021] In some embodiments of the present application, the present application provides relative rotation limitation between the connector and the bracket through the design of the connector structure, and the cost of this solution is relatively low.

[0022] In some embodiments of the present application, the bracket is a hollow circular tube structure, and plugs are installed at both ends of the bracket. One end of the plug is fixed to the bracket, and the other end of the plug is provided with a slot adapted to the connecting piece. The second end of the connecting piece is embedded in the slot, and the connecting piece and the slot cooperate with each other to limit the maximum angle of rotation of the bracket relative to the connecting piece.

[0023] The plug is a solid structure. In the present application, hollow round tubes are used to make the back frame, support rod, handrail tube and bracket, so that the overall structure of the present application is light and convenient for users to carry. At the same time, the structural strength of the beach chair, the stability and reliability of the connection structure must be taken into consideration, so a solid plug is installed at the end of the bracket to meet the structural strength requirements of the beach chair.

[0024] In some embodiments of the present application, the seat cover fabric and the seat back fabric are made of Oxford cloth.

[0025] The above-mentioned implementation modes can be combined arbitrarily based on the common knowledge in the art. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application is described in detail below in conjunction with the accompanying drawings.

[0033] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] A folding beach chair, embodiment 1 Figures 1 to 4 As shown: it includes a seat fabric 1, an armrest tube 2 and a folding chair frame, the folding chair frame includes a back frame 3, two brackets, and two support rods 4, the two support rods 4 are arranged parallel to each other, and the seat fabric 1 is sleeved on the two support rods 4. In this application, the seat fabric 1 is spread out by two support rods 4 to form a seat surface for the user to sit on.

[0035] The bracket is in a U-shaped structure, and the two brackets are hinged at the front and rear ends of the two support rods 4, respectively. The back frame 3 is in an inverted U-shaped structure and is vertically arranged above the two support rods 4, and the back frame 3 is hinged to the rear ends of the support rods 4. The present application adopts a U-shaped structure when designing the bracket and the back frame 3 of the beach chair. The U-shaped structure makes the structure itself have good structural strength, and in the present application, the two brackets and the back frame 3 both play the role of supporting the distance between the two support rods 4. The connection of multiple U-shaped structures makes the two support rods 4 have good support for the seat fabric 1, thereby effectively improving the load-bearing capacity of the beach chair and improving the stability and reliability of the product when in use. Again, the U-shaped structure makes the back frame 3 and the two brackets themselves have good structural strength, and there is no need to add an additional cross skeleton structure to enhance their supporting performance.

[0036] The two ends of the handrail tube 2 are respectively hinged with the ends of the back frame 3 and the ends of the brackets located at the front side. The U-shaped structure allows the user to lie on the application without the back, buttocks and legs touching the skeleton structure, providing a good user experience and high comfort.

[0037] In this application, for the convenience of description, the Figure 1 As a benchmark, the beach chair is in an open state.

[0038] Embodiment 2, as Figures 1 to 4As shown, the two brackets are divided into a front bracket 5 and a rear bracket 6, and the two ends of the rear bracket 6 are respectively connected to the rear end of the support rod 4 through a connecting piece 7. The above structure allows the rear bracket 6 of the beach chair to be flipped and folded relative to the support rod 4, and the rear bracket 6 flips forward to fit the bottom of the support rod 4.

[0039] The rear bracket 6 is hinged to the connecting piece 7, and the rear end of the support rod 4 is fixedly connected to the connecting piece 7. This structure makes the connection joint here more stable and reliable.

[0040] The end of the front bracket 5 is provided with two hinge points 8 staggered up and down, wherein the hinge point 8 located at the upper side is hinged to a connecting member 7 and connected to the front end of the handrail tube 2 through the connecting member 7, and the hinge point 8 located at the lower side is hinged to the front end of the support rod 4. When the front bracket 5 is flipped and folded backward relative to the support rod 4, its upper end will drive the handrail tube 2 to move forward and downward, thereby driving the handrail tube 2 to move downward until it fits with the top of the support rod 4.

[0041] The end of the back frame 3 is provided with two hinge points 9 staggered up and down, wherein the hinge point 29 located at the upper side is hinged to the rear end of the support rod 4, and the hinge point 29 located at the lower side is hinged to a U-shaped frame 10, and is connected to the rear end of the handrail tube 2 through the U-shaped frame 10. The above structure enables the back frame 3 to be flipped and folded relative to the support rod 4, avoiding the back frame 3 from being attached to the support rod 4 when flipping, and the back frame 3 flips forward to fit the bottom of the support rod 4.

[0042] The rear end of the handrail tube 2 passes through the middle of the U-shaped frame 10, the inner bottom surface of the U-shaped frame 10 fits the handrail tube 2, the U-shaped frame 10 is fixedly connected to the handrail tube 2, and the end of the back frame 3 extends into the U-shaped frame 10 and is hinged to the U-shaped frame 10. Similarly, the above structure makes the connection joint here more stable and reliable.

[0043] The back frame 3 is covered with a back cloth 11, which is stretched by the back frame 3, and the top of the back frame 3 is bent backward. The back of the user is supported by the back cloth 11, and the top of the back frame 3 is bent backward, which adapts to the human body structure and provides a good user experience. Secondly, the setting of the bending structure makes the structural strength of the back frame 3 higher.

[0044] The back frame 3 and the handrail tube 2 are covered with a hose pad 12 to improve the comfort of the user contacting the back frame 3 and the handrail tube 2.

[0045] The rest of the content of the second embodiment is the same as that of the first embodiment.

[0046] Embodiment three, as Figures 1 to 4As shown, the connecting member 7 is a curved sheet-like structural member, the first end of the connecting member 7 is connected to the support rod 4 or the handrail tube 2, and the second end of the connecting member 7 is hinged to the bracket. In the present application, the structure of the connecting member 7 can be thickened to enhance the structural strength of the connection and further improve the load-bearing capacity of the present application.

[0047] The second end of the connecting member 7 includes a lower bottom surface 14, a first side surface 15 and a second side surface 16. The first side surface 15 is arranged closer to the support rod 4 than the second side surface 16. A curved surface transition is formed between the first side surface 15 and the lower bottom surface 14. That is, the above structure enables the bracket in the folded state to be flipped outward relative to the support rod 4 to the expanded state.

[0048] The second side surface 16 is a plane, the lower bottom surface 14 of the connecting member 7 is a plane, the bottom surface and the second side surface 16 are connected at a right angle or an acute angle, and the inner bottom surface of the notch is a plane.

[0049] That is, the above-mentioned structural arrangement ensures that when the bracket is flipped over until the inner bottom surface of the groove is parallel to the lower bottom surface 14 of the connecting member 7, or in other words, in a contact state, the bracket reaches the limit position of the travel and is limited by the right angle or acute angle between the bottom surface and the second side surface 16, and the bracket cannot continue to flip outward.

[0050] The present application designs the structure of the connecting member 7 so that the connecting member 7 and the bracket have relative rotation limitation, and the cost of this solution is relatively low.

[0051] The bracket is a hollow circular tube structure, and plugs 13 are installed at both ends of the bracket. One end of the plug 13 is fixed on the bracket, and the other end of the plug 13 is provided with a slot adapted to the connecting member 7. The second end of the connecting member 7 is embedded in the slot, and the connecting member 7 cooperates with the slot to limit the maximum angle of rotation of the bracket relative to the connecting member 7.

[0052] The plug 13 is a solid structure. In the present application, a hollow round tube is used to make the back frame 3, the support rod 4, the handrail tube 2 and the bracket, so that the overall structure of the present application is light and convenient for users to carry. At the same time, the structural strength of the beach chair, the stability and reliability of the connection structure must be taken into consideration, so a solid plug 13 is installed at the end of the bracket to meet the structural strength requirements of the beach chair.

[0053] In the present application, the bracket is formed with high processing precision, so that the plug 13 and the bracket are better connected with each other, and the stability and reliability of the connection joint are improved. In addition, the back frame 3, the support rod 4, the handrail tube 2 and the bracket of the circular tube structure in the present application can be thickened to improve the structural strength of the product and further improve the load-bearing capacity of the product.

[0054] In addition, the materials used to form the back frame 3, support rods 4, handrail tubes 2, brackets and connectors 7 in the present application have undergone high-temperature heat treatment, thereby further improving the structural strength of the materials and thus increasing the maximum load-bearing capacity of the product.

[0055] The seat cover fabric 1 and the seat back fabric 11 are made of Oxford cloth.

[0056] The other contents of the third embodiment are the same as those of the second embodiment.

[0057] The present application is described in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
