This application claims priority to Chinese Patent Applications 202323453960.7 and 202323619894.6, respectively filed on Dec. 18, 2023 and Dec. 27, 2023. Chinese Patent Applications 202323453960.7 and 202323619894.6 are incorporated herein by reference.
The disclosure relates to the technical field of folding chairs, and particularly to a folding hanging chair frame and a hanging chair.
A folding hanging chair typically includes a hanging chair frame and a fabric hanging on the hanging chair frame. The cloth forms a soft chair surface, and can sway with its hanging points on the hanging chair frame as fulcra, so that the user sitting on the fabric can swing. Therefore, this hanging chair is also called a swing chair. Some hanging chair frames have a foldable structure, which is convenient for storage and transportation. The existing folding hanging chairs in the market generally have a large volume after being folded. For example, Chinese patent No. CN219920637U discloses a folding swing chair. After this folding swing chair is folded, only the angles between the bars are changed as compared with its unfolded state, and the bars are still connected with each other, so this folding swing chair in a folded state still occupies a large space, which is not convenient enough for storage and transportation.
In addition, the shape of the existing hanging chair belt in an unfolded state is unchangeable, that is, the user can use the hanging chair only in a “sitting” posture. Moreover, the user in the sitting posture cannot get relaxed completely.
An objective of the disclosure is to provide a folding hanging chair frame and a hanging chair, in order to solve the problem that the existing folding hanging chairs are not convenient enough for storage and transportation.
In order to achieve the above objective, the technical solution of the disclosure includes: a folding hanging chair frame includes a foldable supporting frame part. The supporting frame part includes a cross beam. An extending direction of a straight line formed by connecting two ends of the cross beam is defined as a left-right direction. Left and right ends of the cross beam are respectively provided with a connecting structure and a lateral bracket tube set connected with the cross beam through the connecting structure. The connecting structure is provided with a plurality of connecting holes. The lateral bracket tube set is detachably connected to the connecting holes, and a connecting cable is arranged between the lateral bracket tube set and the connecting structure. The connecting cable keeps the lateral bracket tube set connected with the cross beam.
The technical solution of the disclosure further includes: a hanging chair includes a hanging chair frame and a hanging chair belt hanging on the hanging chair frame. The hanging chair frame is the folding hanging chair frame described above.
In an example, the hanging chair belt is connected with hanging components, and the hanging components are configured to suspend the hanging chair belt onto the hanging chair frame. A front direction when a user uses the hanging chair belt in a sitting posture is defined as front, and an opposite direction as rear. The hanging chair belt includes a seat component and a backrest component arranged at a rear side of the seat component. The seat component and the backrest component form a connection relationship with an adjustable included angle. The hanging components are connected to the hanging chair belt by being respectively connected to the seat component and the backrest component. The hanging components are each provided with an adjusting mechanism located between the seat component and the backrest component. The included angle between the backrest component and the seat component is adjusted by means of the adjusting mechanisms so as to increase postures of using the hanging chair belt.
The disclosure has the following beneficial effects:
To further illustrate the examples, the accompanying drawings are provided in the disclosure. These accompanying drawings are a part of the contents disclosed in the disclosure that are mainly used to illustrate the examples, and can be used in conjunction with the related descriptions in the specification to explain the operation principle of the examples. With reference to these contents, those of ordinary skill in the art should be able to understand other possible embodiments and advantages of the disclosure. Components in the drawings are not drawn to scale, and like component symbols are usually used to represent like components.
Referring to
Firstly, by means of the detachable connection between the lateral bracket tube set 13 and the connecting structure 12, the lateral bracket tube set 13 and the cross beam 11 form a detachable structure, so that the structural members (the lateral bracket tube set 13 and the cross beam 11) of the hanging chair frame can be disassembled. In this way of directly disassembling the structural members of the hanging chair frame, the volume of the folded hanging chair frame will not be limited to the included angles between the structural members, so that the folded hanging chair frame has a smaller volume, which is convenient for storage and transportation. Secondly, with the connecting cable 14 arranged between the lateral bracket tube set 13 and the connecting structure 12, the lateral bracket tube set 13 and the cross beam 11 that are disassembled can be kept connected, which prevents one or more of the structural members from being lost.
The cross beam 11 functions to connect the two lateral bracket tube sets 13, so as to keep the hanging chair frame in the unfolded state balanced. The lateral bracket tube set 13 includes support leg tubes 131 and a supporting tube 132. The support leg tubes 131 are arranged below the connecting structure 12, and the supporting tube 132 is arranged above the connecting structure 12. An upper end of the supporting tube 132 is provided with a hook connecting component 15. In this example, each lateral bracket tube set 13 includes two support leg tubes 131, and the two support leg tubes 131 form a certain included angle. By combining these two support leg tubes with the cross beam 11 and the two support leg tubes 131 on the opposite side, the hanging chair frame is supported at four points, so that the hanging chair frame can be kept balanced and stable. A bottom of each support leg tube 131 is further provided with a rubber support leg sleeve 133, which can protect the support leg tube 131 and the floor where the hanging chair frame is placed and prevent the hanging chair frame from slipping during use. Each supporting tube 132 includes two parallel tube elements. Lower ends of the two tube elements are respectively inserted into one connecting hole 121, and upper ends of the two tube elements are fixedly connected through the hook connecting component 15. One connecting cable 14 is respectively arranged in each support leg tube 131 and each tube element of the supporting tube 132, i.e., a first end of the connecting cable 14 is connected to any support leg tube 131 or the supporting tube 132, and a second end of the connecting cable 14 runs through the corresponding connecting hole 121 and is fixedly connected with the connecting structure 12. When the lateral bracket tube set 13 needs to be demounted, each support leg tube 131 and each tube element of the supporting tube 132 are respectively removed from the connecting holes 121 of the connecting structure 12, so that the cross beam 11 and the lateral bracket tube set 13 can be disassembled, and the connecting cable 14 can keep each support leg tube 131 and each tube element of the supporting tube 132 that are disassembled respectively flexibly connected with the cross beam 11.
The connecting cable 14 may be a rope or a chain, and preferably an elastic rope. If an inelastic rope or a chain is used, when each support leg tube 131 and each tube element of the supporting tube 132 are mounted to the connecting holes 121, the connecting cable 14 should be accommodated into the corresponding tube element.
The connection of each support leg tube 131 and each tube element of the supporting tube 132 with the connecting holes 121 may be a slight interference fit, a threaded fit or a snap fit. In the case of the interference fit, for the convenience of mounting, the tail end of the corresponding tube element should have a certain taper.

The upper end of the supporting tube 132 is provided with a hook connecting plate 153 and a decorative cover 154. The hook connecting plate 153 is fixedly connected to the upper end of the supporting tube 132. The hook connecting plate 153 is provided with a square hole. An end portion of the first connecting portion 1511 of the hook 151 away from the stop portion 1512 is provided with a square stop structure 1513. The stop structure 1513 is fitted with the square hole to limit the first connecting portion 1511 of the hook 151 from axial rotation. The first connecting portion 1511 is further fixed with the hook connecting plate 153 by welding. There are two hook connecting plates 153, and the two hook connecting plates 153 are spaced apart, thereby improving the radial stability of the hook 151 and reducing the sway of the hook 151. A lower end of the decorative cover 154 is provided with a cavity for accommodating the supporting tube 132 and the first connecting portion 1511 of the hook. An upper end of the decorative cover 154 is provided with a ceiling insertion hole 1541 for mounting a sunshade supporting member 18. A partition is arranged between the cavity and the ceiling insertion hole 1541. In this example, the hook connecting plates 153 are made of metal plates. The metal plates have high strength, and thus can keep the hanging chair frame stable when the user sways the hanging chair belt, thereby improving the safety and stability of the hanging chair.
In this example, the hook 151 is L-shaped. In other examples, the stop portion 1512 may be in the shape of extending upward to a second end of the first connecting portion 1511 relative to the first end.

The adjusting handle 191 and the rotating base 192 are elastically connected with a limited relative displacement in an axial direction. With this elastic connection, the adjusting handle 191 can be pressed against the rotating base 192, which prevents the adjusting handle 191 and the rotating base 192 from unexpected relative rotation after the angle of the sunshade frame 17 is adjusted in place and functions to stabilize the angle of the sunshade frame 17. In addition, since the elastic connection limits the relative displacement between the adjusting handle 191 and the rotating base 192 to some extent, but not completely, when adjusting the angle of the sunshade frame 17, the adjusting handle 191 is axially displaced along a direction away from the rotating base 192, so that the meshing teeth 1911 of the adjusting handle go across the engaging teeth 1921 to drive the sunshade frame 17 to change its angle. The adjusting handle 191 and the rotating base 192 are elastically connected in the following way: the adjusting handle 191 is provided with a first through hole 1913 at a central axis; the elastic limit member 193 runs through the first through hole 1913, and an end portion of the elastic limit member 193 is provided with a limit portion 1931; a spring is sleeved on the elastic limit member 193, and two ends of the spring respectively abut against end surfaces of the limit portion 1931 and the adjusting handle 191; and there is further provided a riveting member 194 running through the second through hole 1922 of the rotating base 192 to form a rivet connection with the elastic limit member 193. In order to realize reliable meshing between the meshing teeth 1911 and the engaging teeth 1921 and rotation of the adjusting handle 191 relative to the rotating base 192, the elastic limit member 193 and the riveting member 194 are fitted in the axial direction with a clearance, and the clearance is not smaller than the maximum depth of the meshing teeth 1911 and the engaging teeth 1921, so that the meshing teeth 1911 can leave the engaging teeth 1921 in mesh therewith and move to the position of other engaging teeth 1921 so as to mesh with the other engaging teeth 1921. In order to stabilize the angle of the sunshade frame 17 after the sunshade frame 17 is adjusted in place, after the sunshade rotating component 19 is assembled, the spring is in a compressed state between the limit portion 1931 and the adjusting handle 191.
In addition to the spring, an elastic part such as a silicone sleeve may also be arranged between the limit portion 1931 and the adjusting handle 191, so that the end portions of the limit portion 1931 and the adjusting handle 191 can be elastically connected, and thereby, the adjusting handle 191 and the rotating base 192 can be elastically connected in the axial direction.
The hanging chair frame is folded by the following method: referring to
This example is different from Example 1 in that: the hanging chair frame of this example is not provided with any parts (including the sunshade frame 17, the sunshade supporting members 18 and the sunshade rotating components 19) other than the supporting frame part, and a complete hanging chair frame can be formed only by the supporting frame part. In this case, after the hanging chair belt is mounted to the hanging chair frame, a hanging chair without a sunshade is formed. In Example 1, the parts (including the sunshade frame 17, the sunshade supporting members 18 and the sunshade rotating components 19) other than the supporting frame part are arranged in order to add the sunshade on the basis of the hanging chair without the sunshade, thereby forming a sunshade hanging chair suitable for outdoor use.

Two sides of the hanging chair belt 20 are connected with hanging components 30, and the hanging components 30 are configured to suspend the hanging chair belt 20 onto hooks 151 of the hanging chair frame 10. A front direction when a user uses the hanging chair belt in a sitting posture is defined as front, and an opposite direction as rear. The front-rear direction is the same as the front-rear direction Y in Example 1. The hanging chair belt 20 includes a seat component 21 and a backrest component 22 arranged at a rear side of the seat component 21. The seat component 21 and the backrest component 22 form a connection relationship with an adjustable included angle. The hanging components 30 are connected to the hanging chair belt 20 by being respectively connected to the seat component 21 and the backrest component 22, so that the hanging chair belt 20 is hung on the hanging chair frame 10. The hanging components 30 are each provided with an adjusting mechanism 31 located between the seat component 21 and the backrest component 22. The included angle between the backrest component 22 and the seat component 21 is adjusted by means of the adjusting mechanisms and posture adjustment of the user so as to increase postures of using the hanging chair.
In the disclosure, the included angle between the seat component 21 and the backrest component 22 is adjusted by means of the adjusting mechanisms. When the included angle is smaller, the user can use the hanging chair in a sitting posture. When the included angle is increased, the user can use the hanging chair belt in a half-lying posture, thereby increasing postures of using the hanging chair. Thereby, the user can get relaxed completely.
Referring to
The seat component 21 includes a seat face 211 and armrests 212 arranged on two sides of the seat face 211. There are two hanging components 30 that are respectively arranged on two sides of the seat component 21. The two hanging components 30 have the same structure, and one hanging component will be described below as an example. The hanging component 30 includes a second connecting portion 32, a third connecting portion 33 and a suspension member 34. The second connecting portion 32 connects a front end of the armrest 212 and the suspension member 34, and the third connecting portion 33 connecting a rear end of the armrest 212, the backrest component 22 and the suspension member 34. The third connecting portion 33 is provided with the adjusting mechanism 31. Under combined actions of the adjusting mechanism 31 and posture adjustment of the user, the backrest component 22 rotates front and rear relative to the seat component 21, so that the included angle between the backrest component 22 and the seat component 21 is adjusted. In this example, the second connecting portion 32 is a flexible cable member, which is specifically a woven tape made of a fabric. The cable member is inelastic or slightly elastic, so that when the user uses the hanging chair and exerts forces to the seat component 21, the second connecting portion 32 will not extend or contract or will only extend or contract slightly, and the seat component 21 will not shift excessively due to the extension and contraction of the second connecting portion 32. The slight extension or contraction of the second connecting portion 32 means that the shift caused by the seat component 21 is negligible. The third connecting portion 33 includes a first flexible cable 331, a second flexible cable 332, a third flexible cable 333, a first cable winding support 334 and a second cable winding support 335. A first end of the first flexible cable 331 is connected to the suspension member 34, and a second end relative to the first end is connected to the first cable winding support 334. A first end of the second flexible cable 332 is fixedly connected to the first flexible cable 331, and a second end relative to the first end sequentially runs through the second cable winding support 335 and the first cable winding support 334 and is connected to the backrest component 22. The second flexible cable 332 is respectively connected to the first cable winding support 334 and the second cable winding support 335 in a relative movement manner. A first end of the third flexible cable 333 is connected to the second cable winding support 335, and a second end relative to the first end is connected to the rear end of the armrest 212, so that the second flexible cable 332, the first cable winding support 334 and the second cable winding support 335 form the adjusting mechanism 31. By means of the posture adjustment of the user, the second flexible cable 332 moves relative to the first cable winding support 334 and the second cable winding support 335, so that the backrest component 22 rotates front and rear relative to the seat component 21. The structure of the adjusting mechanism 31 is similar to a pulley block. The first cable winding support 334 is equivalent to a fixed pulley, and the second cable winding support 335 is equivalent to a movable pulley. The displacement of the end portion of the second flexible cable 332, i.e., the relative rotation between the seat component 21 and the backrest component 22, is realized by means of the relative movement between the two pulleys, so that the angle is adjusted. In this example, the first cable winding support 334 and the second cable winding support 335 are both rectangular metal rings, and the second flexible cable 332 is a flat woven tape. The second flexible cable 332 is respectively slidable relative to the first cable winding support 334 and the second cable winding support 335. In other examples, the first cable winding support 334 and the second cable winding support 335 may be pulleys, and the second flexible cable 332 may be a rope. Then, the second flexible cable 332 is respectively rollable relative to the first cable winding support 334 and the second cable winding support 335. In this case, the first flexible cable 331 is connected to a center of the first cable winding support 334 (pulley), and the third flexible cable 333 is connected to a center of the second cable winding support 335 (pulley).
In addition to the structure similar to the pulley block in this example, the adjusting mechanism 31 may also be formed by elastic flexible cables. The second flexible cable 332 may be a flexible cable with high elasticity, and the first flexible cable 331 and the third flexible cable 333 may be inelastic or slightly elastic flexible cables. Moreover, the first cable winding support 334 and the second cable winding support 335 may be eliminated. Compared with the adjusting mechanism in the structure of the pulley block in the above example, the structure using the elastic flexible cables is simpler, but the elastic flexible cables are prone to permanent deformation after long-term use. However, the flexible cables of this example may be inelastic or slightly elastic (which can be ignored), so that even after long-term use, they are not prone to permanent deformation, or their permanent deformation is negligible.
In both of the examples above, the adjusting mechanism 31 needs to be combined with the posture adjustment of the user to adjust the angle between the backrest component 22 and the seat component 21. In other examples, the angle between the backrest component 22 and the seat component 21 may also be adjusted by arranging a tri-glide buckle between the flexible cables of the third connecting portions 33. In this case, the user needs to manually adjust the length of the third connecting portion 33 to adapt to the user's posture (sitting posture, lying posture or the like) of using the hanging chair.
In this example, the suspension member 34 of the hanging component 30 is a hanging ring, and the hanging chair frame 10 is provided with a hook 151. The hanging ring is hung on the hook 151, and the second connecting portion 32 is connected to the hanging ring. The second connecting portion 32 is connected to the hanging chair frame 10 by being connected to the hanging ring. The third connecting portion 33 is also connected to the hanging ring. The third connecting portion 33 is also connected to the hanging chair frame 10 by being connected to the hanging ring. While the hanging chair belt 20 sways front and rear, there will be friction between the hanging ring of the hanging component 30 and the hook 151. The hanging ring has smaller friction and higher wear resistance relative to the second connecting portion 32 and the third connecting portion 33 made of the fabric material, so that the hanging chair belt 20 can sway more smoothly and the service life of the hanging component 30 can be prolonged. In other examples, it is also possible that the second connecting portion 32 and the third connecting portion 33 are directly hung on the hook 151, and in this case, the end portion of the second connecting portion 32 and the end portion of the third connecting portion 33 respectively form the suspension member 34. In addition, the suspension member 34 may also be a hook-shaped hanging hook in addition to the ring-shaped hanging ring.
In this example, a relative position between the backrest component 22 and the seat component 21 is alternatively in a first posture or a second posture, and under combined actions of the hanging component 30 and posture adjustment of the user, the backrest component 22 and the seat component 21 are switched between the first posture and the second posture so as to increase postures of using the hanging chair. The first posture refers to the relative position between the backrest component 22 and the seat component 21 when the user uses the hanging chair in a sitting posture, and the second posture refers to the relative position between the backrest component 22 and the seat component 21 when the user uses the hanging chair in a half-lying posture. Since the adjusting mechanism 31 adjusts the angle by means of the slide of the flexible cables, the relative position between the backrest component 22 and the seat component 21 may also be any position between the first posture and the second posture as long as this position is acceptable to the user.
When the user uses the hanging chair belt in the sitting posture, the center of gravity of the whole of the hanging chair belt and the user keeps the hanging chair belt in the first posture, and the included angle between the backrest component 22 and the seat component 21 is the smallest (
This example provides a hanging chair, which is different from Example 3 in that the structure of the hanging chair frame 10 is different. The hanging chair frame 10 of this example is the structure of Example 1, i.e., has the parts (including the sunshade frame 17, the sunshade supporting members 18 and the sunshade rotating components 19) other than the supporting frame part, thereby forming the hanging chair with a sunshade. The specific structure of the hanging chair frame 10 is the same as in Example 1, and will not be described in detail here.
Although the disclosure has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that the remaining unexplained parts are the prior art and that various changes made thereto in forms and details without departing from the spirit and scope of the disclosure as defined in the appended claims shall fall within the scope of protection of the disclosure.
