DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] It should be noted that if a directional indication is involved in the embodiments of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0047] In this specification, position terms such as "upper", "lower", and "top" are defined according to the position of the seat during use.

[0048] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0049] In view of the fact that the functions of sunshade structures for seats in the prior art are too single and cannot well meet the needs of folding seats, especially folding beach chairs, the utility model proposes a novel sunshade assembly for seats and a seat including the sunshade assembly.

[0050] Figure 1 and Figure 2 An exemplary embodiment of a sunshade assembly I for a seat (hereinafter referred to as sunshade assembly I) according to the utility model is shown, and the sunshade assembly I includes a sunshade frame 100 and a first sunshade surface 200. The sunshade frame 100 includes a pair of first rods 110 and a second rod 120 disposed between the pair of first rods 110, the pair of first rods 110 are parallel to each other and have a first end 110A and a second end 110B, the first end 110A and the second end 110B face opposite directions, and the second rod 120 is perpendicular to the first rod 110 and connected between the first ends 110A of the pair of first rods 110, so that the frame 100 is substantially U-shaped, as shown in FIG. Figure 2 The second rod 120 and the pair of first rods 110 together define a frame opening 100A, and the first sunshade surface 200 is disposed on the sunshade frame 100 and covers the frame opening 100A, so that after the sunshade frame 100 is connected and installed to the upper end of the seat back, the first sunshade surface 200 can be used for sunshade. Preferably, the second rod 120 and the pair of first rods 110 are formed by bending a continuous rod-shaped member or a tubular member to form a U-shaped shape.

[0051] In some embodiments, the sunshade assembly I may further include an auxiliary sunshade member 300, which includes a pair of auxiliary rods 310 and a second sunshade surface 320 arranged between the pair of auxiliary rods 310, and the pair of auxiliary rods 310 each have a connecting end 310A and a free end 310B. At the same time, the pair of auxiliary rods 310 are slidably connected to the pair of first rods 110 through their respective connecting ends 310A, and then the shading area of ​​the entire sunshade assembly I can be adjusted as needed by sliding the auxiliary sunshade member 300 relative to the sunshade frame 100, such as Figure 3 The seat II shown includes a sunshade assembly I. In some embodiments, the pair of first rods 110 are configured as tubular members, and the connecting ends 310A of the pair of auxiliary rods 310 are respectively inserted into the pair of first rods 110 from the second ends 110B of the pair of first rods 110 and can slide along the axial direction of the pair of first rods 110 to adjust the sunshade area of ​​the entire sunshade assembly I.

[0052] In some embodiments, the second awning surface 320 is made of a flexible material (such as fabric) and has a first side 320A and a second side 320B opposite to each other, the first side 320A is disposed between the free ends 310B of the pair of auxiliary rods 310, and the second side 320B can be attached to the first awning surface 200, and the attachment method includes but is not limited to sewing or detachably sticking through Velcro, etc. In this way, the second awning surface 320 is connected to the free ends 310B of the pair of auxiliary rods 310 only at the two ends of its first side 320A, so as not to hinder the pair of auxiliary rods 310 from sliding into or out of the pair of first rods 110. At the same time, when the auxiliary rod 310 slides out from the first rod 110, the first side 320A moves away from the second side 320B, the second awning surface 320 gradually stretches, and the shading area increases; when the auxiliary rod 310 slides into the first rod 110, the first side 320A approaches the second side 320B, the second awning surface 320 gradually wrinkles, and the shading area decreases.

[0053] It should be understood that the first awning surface 200 and the second awning surface 320 can be made of any suitable material, including but not limited to fabric (including cloth, leather, etc. and combinations thereof), plastic, rubber, etc. and combinations thereof.

[0054] Figure 3 and Figure 4An exemplary embodiment of a seat II according to the utility model is shown, and the seat II includes a seat body 400 and a seat back 500 disposed on the seat body 400. The above-mentioned sunshade assembly I is disposed at the upper end of the seat back 500 and can be used for sunshade. The seat back 500 includes a seat back cross bar 520 and a pair of seat back longitudinal bars 510. The seat back cross bar 520 is connected between the top ends of the pair of seat back longitudinal bars 510, and the pair of seat back longitudinal bars 510 are disposed on the seat body 400. The sunshade assembly I is disposed on the seat back cross bar 520 in an angle-adjustable manner. The angle of the sunshade assembly I relative to the seat back 500 can be adjusted as needed. For example, the sunshade assembly I can be rotated / flipped relative to the seat back 500 within a range of 0° to 360°. Figure 3 , Figure 5 and Fig.15 The states of the sunshade assembly I flipped to different angles relative to the seat back 500 are respectively shown.

[0055] In some embodiments, Figure 6 to Figure 7 As shown, the seat II further includes a rotation locking member 600, and the second rod 120 is substantially parallel to the backrest cross bar 520 and is arranged on the backrest cross bar 520 in an adjustable angle through the rotation locking member 600, so that the sunshade assembly I can rotate / turn relative to the backrest 500, thereby adjusting the angle between it and the backrest 500. The rotation locking member 600 includes an elastic element 610, a rotating element 620, a fixed element 630 and a shaft 640. The shaft 640 is inserted in the rotating element 620 and the fixed element 630 so that the rotating element 620 and the fixed element 630 can rotate relative to each other coaxially around the shaft 640, and the rotating element 620 and the fixed element 630 are fixedly connected to the second rod 120 and the backrest cross bar 520 respectively, so that the angle of the sunshade assembly I relative to the backrest 500 is adjusted by the relative rotation between the rotating element 620 and the fixed element 630. At the same time, the rotating element 620 and the fixed element 630 have structures that can be engaged with each other and are arranged circumferentially along the axis 640, and the elastic element 610 can bias the rotating element 620 toward the fixed element 630, so that under the biasing force of the elastic element 610, the structures that can be engaged with each other on the rotating element 620 and the fixed element 630 are in an engaged state, the rotating element 620 and the fixed element 630 are circumferentially fixed to each other, and the sunshade assembly I is fixed at an angle relative to the chair back 500.

[0056] When the angle between the sunshade assembly I and the chair back 500 is to be adjusted, the rotating element 620 or the sunshade assembly I is moved along the axial direction of the shaft 640 to overcome the biasing force of the elastic element 610 under the action of an external force (such as manually), so that the rotating element 620 is away from the fixed element 630, and the mutually engageable structures on the rotating element 620 and the fixed element 630 are in a disengaged state, and the rotating element 620 can rotate relative to the fixed element 630 to adjust the angle of the sunshade assembly I relative to the chair back 500. Afterwards, the external force is removed, and the elastic element 610 (with the help of the shaft 640) biases the rotating element 620 toward the fixed element 630, and the mutually engageable structures on the rotating element 620 and the fixed element 630 engage again, and the sunshade assembly I can be maintained at a suitable angle relative to the chair back 500.

[0057] It should be understood that the elastic element 610 can be configured as a compression spring or an elastic sheet. Figure 7 and Figure 8 The diagram shows that the elastic element 610 is configured as a compression spring and is inserted through a shaft 640 configured as a bolt. Limiting members (including a bolt head 641, a nut 642 and an end cover 643) are provided at both ends of the shaft 640. The elastic element 610 is compressed between the end cover 643 and the fixed element 630, and the biasing force of the elastic element 610 is transmitted to the rotating element 620 through the shaft 640.

[0058] In some embodiments, the rotating element 620 and the fixed element 630 have a contact surface 621 and a contact surface 631, respectively, and the mutually engaging structure can be configured as a plurality of grooves distributed circumferentially around the axis 640 on one contact surface and a protrusion disposed on another contact surface and matching the plurality of grooves. The sunshade assembly I is adjusted to and maintained at different angles relative to the chair back 500 by disengaging and engaging between the protrusions and different grooves, so that the angle of the sunshade assembly I can be adjusted. In particular, in other embodiments, the mutually engaging structure is configured as a pair of mutually engaging face gears 621A and 631A, the face gear 621A and the face gear 631A are disposed on the contact surface 621 and the contact surface 631, respectively, the teeth and tooth grooves of the face gears 621A and 631A are equivalent to the above-mentioned protrusions and grooves, the teeth of the face gear 621A match the tooth grooves of the face gear 631A, and vice versa, that is, the tooth grooves of the face gear 621A match the teeth of the face gear 631A. The teeth and tooth grooves of the face gears 621A and 631A are evenly arranged circumferentially on the contact surfaces 621 and 631 of the rotating element 620 and the fixed element 630, so that when the rotating element 620 rotates one or more tooth pitches, the face gears 621A and 631A can engage with each other again, thereby facilitating the angle adjustment of the sunshade assembly I.

[0059] It should be understood that the use of the above-mentioned pair of face gears 621A, 631A can bring special benefits. Since a large number of teeth are embedded in the tooth grooves when the pair of face gears 621A, 631A are engaged, a large circumferential resistance can be generated to keep the sunshade assembly I at a suitable angle. Based on this, in some embodiments, the height of the teeth of the face gears 621A, 631A and the depth of the tooth grooves can be appropriately reduced, so that the rotating element 620 only needs to slightly move away from the fixed element 630 along the axial direction of the shaft 640 to disengage from the engagement with the fixed element 630, and the rotating element 620 can rotate relative to the fixed element 630. Therefore, the user only needs to flip the sunshade assembly I, so that the teeth of the pair of face gears 621A, 631A are squeezed to realize the axial movement of the rotating element 620 relative to the fixed element 630, without deliberately moving the rotating element 620 or the sunshade assembly I axially to make the rotating element 620 away from the fixed element 630. In particular, the tooth profile of a pair of facing gears 621A and 631A is a triangular tooth profile, so that when the sunshade assembly I is flipped, the direction of the extrusion force between the teeth of a pair of facing gears 621A and 631A (perpendicular to the tooth surface of the teeth) is oblique to the axis 640, so that the component of the extrusion force along the axis 640 causes the rotating element 620 to move axially along the axis 640 relative to the fixed element 630.

[0060] It should also be understood that the number of the rotating locking members 600 can be two or more to ensure the stability of the rotation / flipping of the sunshade assembly I.

[0061] In some embodiments, Figure 4 , Figure 5 and Fig.10 As shown, a pair of backrest longitudinal rods 510 are configured to be telescopic and include a lower tube 511 and an upper tube 512. The lower tube 511 is disposed on the seat body 400, and the upper tube 512 is inserted into the lower tube 511 from the top end of the lower tube 511 and can slide along the axial direction of the lower tube 511 to adjust the height of the entire backrest 500, and the backrest cross bar 520 is connected between the top ends of the upper tubes 512 of the pair of backrest longitudinal rods 510. Preferably, the backrest cross bar 520 and the pair of upper tubes 512 are formed by bending a continuous tubular member to form an inverted U shape. In some embodiments, a clamping assembly 700 is fixedly provided on the lower tube body 511, and the clamping assembly 700 can release or clamp the upper tube body 512, so that by releasing the upper tube body 512, the height of the chair back 500 can be adjusted by sliding the upper tube body 512, and by clamping the upper tube body 512, the upper tube body 512 no longer slides and the height of the chair back 500 is fixed.

[0062] In certain embodiments, such as Figures 9 to 13As shown, the clamping assembly 700 includes a fixing portion 710, a clamping sleeve 720 and an adjusting member 730. The fixing portion 710 can be configured as a tube and fixedly sleeved on the lower tube 511. The clamping sleeve 720 is fixedly connected to the fixing portion 710 and has a pair of elastic suspension wing plates 721. The pair of elastic suspension wing plates 721 extend toward each other along the outer periphery of the upper tube 512 and embrace the upper tube 512, so that the clamping sleeve 720 is sleeved on the upper tube 512 and a gap 722 is formed between the free ends 721A of the pair of elastic suspension wing plates 721. As the name implies, the elastic suspension wing plate 721 is elastic. The adjusting member 730 is connected to the pair of elastic suspension wing plates 721 and is configured to adjust the size of the gap 722, thereby allowing the pair of elastic suspension wing plates 721 to elastically open or close to release or clamp the upper tube 512.

[0063] Specifically, the adjusting member 730 includes a first mounting portion 731, a second mounting portion 732, a cam 733 and a pull rod 734. The first mounting portion 731 and the second mounting portion 732 are respectively fixedly arranged on the free ends 721A of a pair of elastic suspension wing plates 721, and first mounting holes 731A and second mounting holes 732A opposite to each other are provided on the first mounting portion 731 and the second mounting portion 732. One end of the pull rod 734 is connected to the first mounting portion 731, and the other end of the pull rod 734 is sequentially inserted through the first mounting hole 731A and the second mounting hole 732A and is hinged to the cam 733. The cam 733 has a convex portion 733A. When the cam 733 rotates forwardly around the hinge point between the cam 733 and the pull rod 734, the convex portion 733A can rotate to contact the second mounting portion 732 and gradually increase the squeezing of the second mounting portion 732, while pulling the pull rod 734 and the first mounting portion 731, so that the second mounting portion 732 and the first mounting portion 731 are close to each other, the interval 722 becomes smaller, and the pair of elastic suspension wing plates 721 are elastically deformed, closed and clamped on the upper tube body 512; conversely, when the cam 733 rotates reversely around the hinge point between the cam 733 and the pull rod 734, the convex portion 733A can rotate to gradually reduce the squeezing of the second mounting portion 732, the elastic suspension wing plates 721 elastically recover under the action of their elastic force, the second mounting portion 732 and the first mounting portion 731 move away from each other, the interval 722 becomes larger, and the pair of elastic suspension wing plates 721 release the upper tube body 512. In a further embodiment, Fig.11 As shown, a lever rod 735 extends (e.g., extends tangentially) from the outer periphery of the cam 733, e.g., from the other side of the cam 733 opposite to the protrusion 733A, so that the cam 733 can be easily rotated around the hinge point between the cam 733 and the pull rod 734 by the lever rod 735. Preferably, when a pair of elastic suspension wing plates 721 clamp the upper tube 512 in place, the lever rod 735 is abutted against one of the elastic suspension wing plates 721, as shown in FIG. Fig.10 and Fig.13 shown.

[0064] In some embodiments, the backrest 500 is arranged on the seat body 400 in a manner that allows the angle to be adjusted. For example, if the seat II is configured as a beach chair, the backrest 500 can be rotated or flipped relative to the seat body 400. Fig.14 As shown, the seat II further includes a pull plate 410 and a clamp 420. The lower end of the seat back longitudinal rod 510 or the lower tube 511 is hingedly arranged on the seat body 400, and the pull plate 410 is hingedly connected to the seat back longitudinal rod 510 or the lower tube 511. A plurality of ratchet teeth 411 are arranged on the pull plate 410, and ratchet grooves 412 are formed between adjacent ratchet teeth 411. The clamp 420 (such as a clamp block) arranged on the seat body 400 can be clamped into different ratchet grooves 412, so as to adjust the angle of the seat back 500 relative to the seat body 400. Specifically, the pull plate 410 can rotate around the hinge point between the pull plate 410 and the seat back longitudinal rod 510 or the lower tube 511, so that the clamp 420 is engaged with or disengaged from the ratchet groove 412, and the clamp 420 is selectively engaged with (engaged with) any one of the plurality of ratchet grooves 412, so that the seat back 500 is rotated or flipped relative to the seat body 400 around the hinge point between the pull plate 410 and the seat back 500 can be maintained at different rotation / flip angles relative to the seat body 400, so that the seat II has different forms, including a sitting form (such as a sitting form).
