Description

Technical Field

[0001] This utility model relates to the technical field of installing plates on dining chairs, and in particular to a children's dining chair with two locking mechanisms. Background Technology

[0002] In the existing technology, during the assembly of the tray and high chair, the tray is locked to the high chair by a locking mechanism. If the infant kicks or accidentally touches the unlock button during use, causing the tray to fall off, the high chair will be missing the tray, creating an opening. If the infant is in a high high chair and is not wearing a safety belt, there is a risk of falling, which seriously endangers the infant's safety. Utility Model Content

[0003] The purpose of this utility model is to provide a children's high chair with two locking mechanisms, which improves the locking security of the tray and the high chair body, thereby solving the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] A children's high chair with two locking mechanisms includes a high chair body and a tray. The high chair is characterized by further including a first locking mechanism and a second locking mechanism located on the tray, which locks or unlocks the first locking mechanism. When the second locking mechanism is unlocked, the first locking mechanism moves to unlock or lock the tray and the high chair body.

[0006] Furthermore, it also includes a movable shell that locks or unlocks the dinner plate via a second locking mechanism, wherein the first locking mechanism that locks the chair body and the dinner plate is linked to the movable shell.

[0007] Furthermore, a driving mechanism is formed at the location of the movable shell away from the second locking mechanism, and the driving mechanism is linked with the first locking mechanism.

[0008] Furthermore, the movable shell or the bottom of the plate is provided with a locking cavity, and the other is provided with a locking part that moves along the locking cavity to lock or unlock the movable shell and the plate.

[0009] Furthermore, it also includes an unlocking button that is linked to the locking part, and the movement of the unlocking button causes the locking part to disengage from the locking cavity.

[0010] Furthermore, a seating area is formed between the plate and the chair body, and the second locking mechanism is disposed away from the seating area.

[0011] Furthermore, the second locking mechanism is located at the bottom of the plate and near the edge of the plate.

[0012] Furthermore, the dining chair body is provided with armrests, and the armrest side is provided with slots. When the drive mechanism moves, the locking member in the first locking mechanism moves into or away from the slot.

[0013] Furthermore, both the plate and the chair body are equipped with magnetic attraction mechanisms, and after the plate and the chair body are assembled, the magnetic attraction mechanisms at corresponding positions have opposite magnetic properties.

[0014] Furthermore, each of the magnetic attraction mechanisms includes two magnetically opposite structures. The beneficial effects of this utility model are as follows: This invention employs two locking mechanisms, requiring the activation of both sides of the tray and chair body to fully unlock them, thereby improving the assembly stability of the tray and chair body and enhancing the safety of the children's high chair during use.

[0016] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0017] See attached document Figure 1-9 As shown, this embodiment of a children's high chair with two locking mechanisms includes a high chair body 100 and a tray 200, a first locking mechanism 300, and a second locking mechanism 400 located on the tray 200, which locks or unlocks the first locking mechanism 300. When the second locking mechanism 400 is unlocked, the first locking mechanism 300 moves to unlock or lock the tray 200 and the high chair body 100. In this embodiment, the control action between the first locking mechanism 300 and the tray 200 and the high chair body 100 can only be performed after the second locking mechanism is unlocked. Even if a child accidentally touches the second locking mechanism, the first locking mechanism must be unlocked to unlock the entire tray, thus reducing the safety risk caused by accidental touches by infants or others.

[0018] In order to associate with and control the locking of the first locking mechanism, a movable shell 500 is provided in this embodiment. The locking or unlocking of the movable shell 500 with the plate 200 forms a second locking mechanism 400. Then, the first locking mechanism 300 and the movable shell 500 are linked, so that once the movable shell 500 is locked and cannot move, the first locking mechanism 300 is also locked. Specifically, in this embodiment, a driving mechanism 510 is formed on the movable shell 500 away from the second locking mechanism 400, and the driving mechanism is linked with the first locking mechanism 300.

[0019] In this embodiment, the first locking mechanism and the second locking mechanism can be positioned close to the middle of the movable shell, especially the second locking mechanism, which is placed in the middle of the movable shell, thereby keeping it away from the operating range of infants and young children and improving safety.

[0020] At this point, the locking member 310, which drives the first locking mechanism 300 to complete the entire unlocking or locking action, is unable to move in some situations due to the presence of the limiting cavity, thus preventing unlocking or locking control. In this case, the first locking mechanism 300 is completely locked and cannot move. The limiting cavity not only restricts the first locking mechanism 300's range of motion, such as in the front-to-back direction, making the overall structure compact, but also restricts the movement of the movable shell in some situations, thus making better use of the space.

[0021] In this embodiment, the movable shell 500 serves, in a sense, to protect the second locking mechanism 400. For example, after the movable shell 500 is placed over the bottom of the plate 200, the locking cavity 410 is located inside the movable shell 500. At this time, the movable shell 500 is positioned away from the front of the plate 200, which is not only aesthetically pleasing but also prevents the second locking mechanism 400 from being easily exposed. The large coverage area ensures that the second locking mechanism 400 remains within the movable shell 500 during movement, making it relatively less likely for children to come into contact with it.

[0022] The specific structure of the second locking mechanism 400 is described below: In this embodiment, a locking cavity 410 is first provided in the bottom of the movable shell 500 or the plate 200, and a locking part 420 is provided along the locking cavity 410 to lock or unlock the movable shell 500 and the plate 200. In this embodiment, the locking cavity 410 can be fixedly set on the plate 200, and the locking part can be movably set between the two, which facilitates its adjustment for unlocking or locking. Of course, it can be set in the space between the movable shell and the plate, which not only conceals the structure and makes it aesthetically pleasing, but also maximizes space utilization.

[0023] See attached document Figure 4-7 As shown, it also includes an unlocking key 430 that is linked to the locking part 420. When the unlocking key 430 moves, it causes the locking part 420 to disengage from the locking cavity 410.

[0024] See attached document Figure 4-5 As shown in the attached figure, in this embodiment, the direction of movement of the unlocking key 430 when it is subjected to force can be either horizontal (on the same horizontal plane as the movable shell 500) or vertical. Specifically, referring to the attached figure, the unlocking key 430 moves horizontally, and its movement is on the same horizontal plane as the driving mechanism 510 in the subsequent first locking mechanism 300.

[0025] Of course, refer to the appendix Figure 6-7 As shown, the unlock button 430 can also move vertically up and down, in which case it moves perpendicular to the subsequent drive mechanism 510. At this time, the inclined surface on the unlock button 430 matches the locking part 420. As the unlock button 430 moves upward, it moves along the inclined surface, thereby disengaging the locking part 420 from the locking groove. Conversely, as the unlock button 420 moves downward, it enters the unlocking groove to complete the unlocking process.

[0026] In this embodiment, to prevent infants from touching it, the second locking mechanism 400 is positioned away from the area accessible to infants. In actual use, infants typically sit within the seating area formed between the tray 200 and the chair body 100. Therefore, the second locking mechanism 400 is positioned at the edge, away from the seating area. During infant activity, their legs are far from the second locking mechanism 400 and generally will not touch it, thus preventing the tray from falling off.

[0027] In actual assembly, the second locking mechanism 400 is located at the bottom of the plate 200, so that infants and young children will not touch it or easily notice it. It is also located near the edge of the plate 200, which is one of the measures to protect it.

[0028] The first locking mechanism 300 is described below: See attached document Figure 1 As shown, the dining chair body 100 in this embodiment is provided with an armrest 110. The first locking mechanism 300 is located on the side of the armrest 110 and the plate 200. At this time, a slot 120 is provided at the armrest 110. Then, the drive mechanism 510 at the end of the movable shell 500 is linked with the locking member 310 in the first locking mechanism 300. Then, the first locking mechanism 300 is symmetrically arranged on both sides of the armrest 110. When the movable shell 500 moves, the two locking members move closer or further away from each other, so that the locking members disengage or insert into the slot 120. In this embodiment, the slot 120 can be provided inside the enclosure cavity formed at the bottom of the armrest. This arrangement is not only concealed, but also allows for cooperation through the armrest.

[0029] In this embodiment, the locking element is a movable plate, and the bottom of the movable plate 320 extends to form a stop cavity. A reset spring 330 is provided at the bottom of the stop cavity between the drive mechanism 510 for subsequent auxiliary reset.

[0030] In this embodiment, in order to prevent the movable shell 500 from moving excessively, a limiting groove 520 is provided on the movable shell 500, and then the plate 200 extends to form a limiting body 210 that is inserted into the limiting groove 520. When the two ends of the limiting groove 520 contact the limiting body 210, two limiting points are formed.

[0031] In this embodiment, a fixing shell 600 is also provided at the bottom of the plate 200, and then the locking member 310 and the limiting body 210 are set inside the fixing shell 600 for a hidden design.

[0032] In this embodiment, a magnetic connection is also provided, as detailed below: See attached document Figure 7-9As shown, both the plate 200 and the chair body 100 are equipped with magnetic attraction mechanisms 700, and after the plate 200 and the chair body 100 are assembled, the magnetic properties of the magnetic attraction mechanisms 700 at corresponding positions are opposite. This reverse magnetic attraction ensures the firmness of the magnetic connection.

[0033] Furthermore, each magnetic attraction mechanism 700 includes two magnetic structures, and the two magnetic structures here have opposite magnetisms. Two magnetic structures are set on the armrest, and two magnetic structures are also set on the bottom of the plate, each with one N pole and one S pole. This setting allows the two magnetic structures to be accurately aligned and attracted, improving the positional accuracy after assembly and avoiding misaligned assembly.

[0034] In this embodiment, the spacing between two adjacent magnetic structures on the same side is 12-16mm, which not only makes the structure compact, but also ensures that the magnetic attraction is not particularly weak, making it difficult for infants and young children to disassemble directly.

[0035] For the assembly of the magnetic attraction mechanism 700, the chair body 100 may be partially recessed to form a first overlapping cavity with the armrest 110; then the tray extends downward to form an overlapping post partially located on the first overlapping cavity; when the first locking mechanism is locked, the magnetic attraction corresponds, completing the secondary assembly and fixation. In this embodiment, there are at least two magnetic attraction structures at the overlapping cavity, and the magnetism between adjacent magnetic attraction structures is opposite.

[0036] This invention cleverly utilizes the principle of a double lock, which not only prevents the tray from falling off due to children's accidental operation, but also cleverly designs the movable shell, allowing most of the structure to be hidden. The unlocking button 430 can be set at the bottom of the tray 200. For example, the bottom of the tray 200 protrudes to form an assembly shell, which can then cooperate with the movable shell 500 to form a complete locking mechanism. The unlocking button is located inside the assembly shell, making it difficult to find even when standing in front of the high chair, thus providing good privacy and high security.

[0037] In this embodiment, the movable shell 500 moves between the fixed shell 600 and the plate, and is in a relatively suspended position.
