Description

Technical Field

[0001] The utility model relates to the technical field of children's products, in particular to a folding dining chair for children. Background Art

[0002] As children grow up, they have to learn to eat by themselves. However, the size of common tables and chairs often does not match the size of children, making it difficult for children to use them properly. Therefore, many families and restaurants will prepare special children's dining chairs for children to use, so that children can eat more easily. In order to allow the children sitting on them to match the height of the dining table, the lower end of this type of children's dining chair usually has longer legs. Some children are also more active. In order to prevent the children from shaking and causing the children's dining chair to fall over, the legs of the children's dining chair are generally designed to extend outward to improve the stability of the children's dining chair.

[0003] The existing technology still has the following deficiencies:

[0004] Since such dining chairs are generally large in size and irregular in shape, they take up a lot of space and are extremely inconvenient to transport and store. Therefore, foldable children's dining chairs have appeared on the market, but these foldable children's dining chairs cannot maintain the unfolded state well, or the components are very loose after disassembly, which is also extremely inconvenient to assemble next time.

[0073] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0074] [Example 1]

[0075] like Figure 1-Figure 4 A folding dining chair for children is shown, comprising:

[0076] Back panel 2;

[0077] A seat plate 4, the rear end of which is hinged to the back plate 2;

[0078] A first side panel, the rear end of which is hinged to the back panel 2;

[0079] A second side panel, a rear end of which is hinged to a front end of the first side panel;

[0080] The front plate 3 is hinged to the front end of the second side plate.

[0081] In this embodiment, a first side panel a5 and a first side panel b51 are provided, and the first side panel a5 and the first side panel b51 are symmetrically arranged on both sides of the seat plate 4, the second side panel a6 is hinged at the front end of the first side panel a5, and the second side panel b61 is hinged at the front end of the first side panel b51.

[0082] The front plate 3 is formed with a sliding groove 31, in which a locking member 7 is slidably arranged, and a female lock buckle 71 is formed on the locking member 7, and a male lock buckle 41 is formed on the seat plate 4. When the folding dining chair 1 is in the unfolded state, the seat plate 4 abuts against the upper end of the front plate 3, and the male lock buckle 41 can cooperate with the female lock buckle 71 to achieve locking, thereby preventing the front end of the seat plate 4 from being separated from the front plate 3.

[0083] At this time, one side of the seat panel 4 abuts against the first side panel a5 and the second side panel a6, and the other side of the seat panel 4 abuts against the first side panel b51 and the second side panel b61, restricting the folding of the first side panel a5 and the second side panel a6, the first side panel b51 and the second side panel b61, thereby maintaining the folding dining chair 1 in the unfolded state.

[0084] Specific as Figure 4 and Figure 5 As shown, a reset assembly is provided in the sliding groove 31 , and the reset assembly is used to make the locking member 7 abut against one end in the sliding groove 31 , so that the locking member 7 can be stably located in the locking position.

[0085] The upper end of the front plate 3 is provided with an escape groove 36. When the locking member 7 is in the locked position, the female lock buckle 71 is located below the escape groove 36. It is convenient for the male lock buckle 41 to pass through the escape groove 36 and cooperate with the female lock buckle 71 to achieve locking between the seat plate 4 and the front plate 3.

[0086] The female lock buckle 71 is formed with a locking protrusion 711, and one side of the locking protrusion 711 is formed with a boosting inclined surface 712. The male lock buckle 41 is provided with a locking hole 42, and the end of the male lock buckle 41 is formed with a pushing inclined surface 43.

[0087] After the push inclined surface 43 contacts the boosting inclined surface 1 712, the locking member 7 can be pushed to move in the sliding groove 31. The male lock buckle 1 41 continues to move downward, and eventually the locking protrusion 1 711 is placed in the lock hole 1 42, thereby limiting the male lock buckle 1 41 from being separated from the avoidance groove 36, so that the front end of the seat plate 4 can be stably connected to the upper end of the front plate 3.

[0088] Further, such as Figure 2-Figure 6 As shown, the locking member 7 is formed with a control portion 73, and when the locking member 7 is disposed in the sliding groove 31, the control portion 73 is exposed from the unlocking hole 32. The user can drive the locking member 7 to move in the sliding groove 31 through the control portion 73, so that the locking protrusion 1 711 is separated from the locking hole 1 42, and the locking between the seat plate 4 and the front plate 3 is released. In this way, the seat plate 4 can be lifted upward, so that the first side plate a5 and the second side plate a6, the first side plate b51 and the second side plate b61 can be folded.

[0089] As a preferred embodiment, the two ends of the front panel 3 are hinged to the front end of the second side wall a6 and the front end of the second side wall b61 respectively. When the folding dining chair 1 is folded, the first side panel a5, the second side panel a6, the first side panel b51 and the second side panel b61 are folded, which can drive the front panel 3 to approach the back panel 2, so that the folding dining chair 1 can be folded.

[0090] picture Figure 1-Figure 6As shown, the sliding groove 31 is arranged on the rear end surface of the front plate 3 , and an unlocking hole 32 is also opened on the front end surface of the front plate 3 , and the unlocking hole 32 leads to the sliding groove 31 .

[0091] The control part 73 may be provided with a connecting rod or a protrusion extending out of the unlocking hole 32 . When the folding dining chair 1 is unfolded, the user can easily move the locking member 7 in the sliding groove 31 by pushing the connecting rod or the protrusion from the outside of the folding dining chair 1 .

[0092] In this embodiment, if Figure 1-Figure 6 As shown, a through hole 74 is formed on the control part 73, so that the control part 73 is formed into a ring shape. The user can pass the finger through the unlocking hole 32 and then into the through hole 74, and can drive the locking member 7 to move in the sliding groove 31.

[0093] Since the control part 73 adopts the structure of the through hole 74, the control part 73 will not extend out of the unlocking hole 32, thereby preventing the part extending out of the unlocking hole 32 from easily scratching the child's legs. It can also prevent the control part 73 from being accidentally touched, resulting in the seat plate 4 and the front plate 3 being separated.

[0094] As a preferred embodiment, two locking members 7 are arranged in the sliding groove 31, and the locking positions of the two locking members 7 are respectively located at the two ends of the sliding groove 31. When performing the unlocking action, the user can use the thumb and index finger of one hand to simultaneously extend into the through hole 74, and then use the thumb and index finger to simultaneously pull the locking member 7 to the middle of the sliding groove 31 to simultaneously unlock the two ends of the front plate 3 and the seat plate 4. The other hand can lift up the seat plate 4, which is convenient for the user to operate.

[0095] Specific as Figure 5 and Figure 6 As shown, a component groove 75 is formed in a recessed manner on the locking member 7, and a return spring 752 is arranged in the component groove 75.

[0096] A spring fixing seat 751 is formed in the component groove 75, and the spring fixing seat 751 is used to fix one end of the return spring 752. A supporting portion is formed in the sliding groove 31, and the other end of the return spring 752 is against the supporting portion.

[0097] The reset spring 752 is used to drive the locking member 7 to reset in the sliding groove 31 so that the locking member 7 can be stably located in the locking position.

[0098] When the locking member 7 is arranged in the sliding groove 31, the component groove 75 and the sliding groove 31 cooperate to form a spring cavity 753, and the abutting portion is located in the spring cavity 753, so that one end of the return spring 752 can abut on the abutting portion, and the other end is sleeved on the outside of the spring fixing seat 751.

[0099] like Figure 2 and Figure 5-Figure 7 As shown, in this embodiment, the abutting portion is a bolt seat 34 , and the bolt seat 34 is used to connect the fixing member 8 .

[0100] The fixing member 8 includes a screw hole 81 formed on the upper portion. The screw hole 81 penetrates the fixing member 8 so that the fixing member 8 can be connected to the bolt seat 34 by means of bolts.

[0101] A waist-shaped hole 754 is formed at the bottom of the component groove 75 . When the fixing member 8 is connected to the bolt seat 34 , the fixing member 8 needs to pass through the waist-shaped hole 754 and then be connected to the bolt seat 34 .

[0102] One end of the fixing member 8 is protruded to form a limit rib 82. When the fixing member 8 is connected to the bolt seat 34, the fixing member 8 partially passes through the waist-shaped hole 754 to connect with the bolt seat 34, and the limit rib 82 cannot pass through the waist-shaped hole 754, and the limit rib 82 can abut against the rear end surface of the component groove 75, thereby limiting the locking member 7 from being separated from the sliding groove 31.

[0103] Since the fixing member 8 can move in the waist-shaped hole 754 , the locking member 7 can move in the sliding groove 31 .

[0104] like Figure 1-Figure 7 As shown, a travel limiting portion 76 is formed on the locking member 7, and a travel limiting groove 33 is also formed on the front plate 3. The travel limiting groove 33 is connected to the sliding groove 31, and a step portion 35 is formed between the travel limiting groove 33 and the sliding groove 31.

[0105] When the locking member 7 is disposed in the sliding groove 31 , the travel limiting portion 76 is inserted into the travel limiting groove 33 .

[0106] A limit protrusion 77 is protruded on the stroke limiting portion 76 . When the locking member 7 moves a set distance toward the inside of the sliding groove 31 , the limit protrusion 77 can abut against the step portion 35 , thereby limiting the moving distance of the locking member 7 in the sliding groove 31 .

[0107] In the present embodiment, two locking members 7 are provided in the sliding groove 31, and the seat plate 4 can be separated from the front plate 3 only when the two locking members 7 are unlocked at the same time, so it is necessary to limit the moving distance of the locking members 7 in the sliding groove 31 to prevent the locking members 7 from interfering with each other in the unlocking action.

[0108] The above-mentioned set distance should also ensure that when the limiting protrusion 77 abuts against the step portion 35, the locking protrusion 711 can be completely extended from the lock hole 42, and the locking protrusion 711 will not prevent the male lock buckle 41 from disengaging through the avoidance groove 36.

[0109] like Figure 6-Figure 10As shown, a second female lock buckle 72 is formed on the locking member 7, and a second male lock buckle 62 is formed on the second side plate.

[0110] When the folding dining chair 1 is in the folded state, the male lock buckle 62 can cooperate with the female lock buckle 72 to lock, so that the folded state of the folding dining chair 1 is locked, so that the front plate 3, the seat plate 4, the back plate 2, the first side plate and the second side plate can also be stably connected together in the folded state, which not only reduces the volume during storage, but also facilitates transportation. When it needs to be unfolded again, the locking state between the male lock buckle 62 and the female lock buckle 72 can be released, so that the folding dining chair 1 can be quickly unfolded, which is convenient for users to use.

[0111] Furthermore, the female lock buckle 72 is formed with a locking protrusion 721, and the locking protrusion 721 is formed with a thrust ramp 722. The male lock buckle 62 is provided with a locking hole 63. When the female lock buckle 72 and the male lock buckle 62 are matched, the locking protrusion 721 is inserted into the locking hole 63.

[0112] Moreover, the protruding directions of the locking protrusion 1 711 and the locking protrusion 2 721 are the same, so that the user can release the locking state between the male lock buckle 1 41 and the female lock buckle 1 71 or release the locking state between the male lock buckle 2 62 and the female lock buckle 2 72 in the same way.

[0113] Since the matching manner of the female lock buckle 2 72 and the male lock buckle 2 62 is basically the same as that of the female lock buckle 1 71 and the male lock buckle 1 41, they will not be elaborated here.

[0114] The control part 73 can drive the locking member 7 to move in the sliding groove 31 , and separate the second locking protrusion 721 from the second locking hole 63 , thereby releasing the locking between the second side plate and the front plate 3 .

[0115] like Figure 1-Figure 11 As shown, a table top 9 is also included, and a connecting portion 91 is protrudingly formed on the peripheral side of the table top 9, and a connecting hole 92 is opened on the connecting portion 91.

[0116] A plurality of adjusting protrusions 64 are formed on the second side plate a6 and the second side plate b61.

[0117] When the foldable dining chair 1 is in the unfolded state, the table top 9 can be sleeved on the upper end of the second side panel through the connecting portion 91. By sleeved the connecting portion 91 on different adjustment protrusions 64, the position of the table top 9 on the foldable dining chair 1 can be adjusted, so that the foldable dining chair 1 can meet the use needs of children of different sizes, improve the utilization rate and the comfort of children when dining.

[0118] When the folding dining chair 1 is in the folded state, the table top 9 can be sleeved on the back plate 2 through the connecting portion 91, and an interference fit is formed between the connecting portion 91 and the back plate 2. Thus, the table top 9 and the folding dining chair 1 in the folded state are connected into one body, which is convenient for storage and transportation.

[0119] As a preferred embodiment, the back plate 2 is formed with a connecting protrusion, and the connecting hole 92 can be sleeved on the connecting protrusion, thereby further improving the fixing effect.

[0120] like Figure 1-Figure 13 As shown, a rear leg connecting groove 22 is formed at the lower end of the back plate 2, and the rear leg 21 is detachably connected in the rear leg connecting groove 22.

[0121] The lower ends of the second side panels a6 and b61 are both formed with front leg connecting grooves 65, in which the front legs 69 are detachably connected, and between the front legs 69 there is a footrest cross plate 67 for providing a support point for children to step on.

[0122] Two ends of the footrest cross plate 67 are formed with second sleeve portions 68 , and the two ends of the footrest cross plate 67 can be sleeved on the front legs 69 respectively through the second sleeve portions 68 .

[0123] A support rod 23 is disposed between the rear legs 21 , and sleeve portions 24 are formed at both ends of the support rod 23 , so that the two ends of the support rod 23 can be sleeved on the rear legs 21 respectively through the sleeve portions 24 .

[0124] The upper ends of the front supporting legs 69 and the rear supporting legs 21 are both provided with spring buckles 13 .

[0125] like Fig.10 As shown, the front leg connecting groove 65 is provided with a lock hole 3 66, so that the spring buckle 13 can extend from the lock hole 3. Since the connection mode between the rear leg 21 and the rear leg connecting groove 22 is the same as the connection mode between the front leg 69 and the front leg connecting groove 65, it will not be described in detail.

[0126] Further, in this embodiment, the front leg 69 or the rear leg 21 can be formed by connecting the upper leg 11 and the lower leg 12. The upper leg 11 and the lower leg 12 are provided with a spring buckle 13, and the lower leg 12 is formed with a plug-in portion 15, which can be inserted into the lower end of the upper leg 11, so that the upper leg 11 and the lower leg 12 can be connected to each other.

[0127] The upper leg 11 is formed with a locking hole 414. When the upper leg 11 and the lower leg 12 are connected as a whole, the spring buckle 13 can extend from the locking hole 414, thereby locking the upper leg 11 and the lower leg 12 as a whole. The lower end of the lower leg 12 is detachably connected with a foot 16, thereby further improving the stability of the folding dining chair 1 when in the unfolded state.

[0128] like Fig.12 and Fig.13 As shown, a locking hole 5 25 is opened on the sleeve portion 1 24. When the sleeve portion 1 24 is sleeved on the outside of the upper leg 11 and the lower leg 12, the spring buckle 13 can extend from the locking hole 5 25, thereby fixing the position of the sleeve portion 1 24 and the support rod 23.

[0129] Since the connection mode between the second sleeve portion 68 and the upper leg 11 and the lower leg 12 is the same as the connection mode between the first sleeve portion 24 and the upper leg 11 and the lower leg 12, they will not be described in detail.

[0130] [Example 2]

[0131] like Fig.14 As shown, this embodiment is basically the same as the first embodiment, except that:

[0132] The upper supporting leg 11 and the lower supporting leg 12 are not provided with spring buckles 13 .

[0133] The upper leg 11 forms an interference fit with the inner side wall of the upper leg 11 through the plug-in portion 15, so that the upper leg 11 is connected to the lower leg 12. Similarly, the upper end of the upper leg 11 can also form an interference fit with the rear leg connecting groove 22 and the front leg connecting groove 65 to achieve fixation.

[0134] It should be noted that the structures, proportions, sizes, etc. drawn in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0135] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or may be indirectly connected to the other element through an intermediate element.

[0136] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. 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 this application.
