    DETAILED DESCRIPTION

    [0061] Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings.

    [0062] FIG. 1 to FIG. 4 illustrate one embodiment of a tray 100 and a child chair 200 according to the present disclosure.

    [0063] As shown in FIG. 1 to FIG. 4, the child chair 200 is a high chair that may include an armrest 210, a backrest 230, a seat part 240, and support legs 250. The armrest 210 is detachably connected to the seat part 240. The armrest 210 may have a rod-like structure or other suitable configuration. The backrest 230 and support legs 250 may be made of wood materials, but not limited thereto.

    [0064] For convenience of description, as shown in FIG. 2 and FIG. 4, a direction in which a child seated on the child chair 200 faces is defined as front while an opposite direction is defined as rear. A front-rear direction of the child chair 200 is defined as a longitudinal direction, and a direction perpendicular to the longitudinal direction on a horizontal plane is defined as a transverse direction (i.e., a left-right direction of the child chair 200). The armrest 210 includes a front side wall 210A away from the child and a rear side wall 210B close to the child.

    [0065] Optionally, the child chair 200 may further include a blocking member 220 to prevent the child from sliding off the chair, and a foot pedal 260 mounted on the support legs 250 for the child to step on. The blocking member 220 may be fixedly connected to the armrest 210, either integrally formed or secondarily assembled as a single unit. Compared to conventional high chairs where the blocking member is mounted on the seat part, the configuration of the present disclosure may allow the blocking member 220 to be removed together with the armrest 210. When used as a regular seat, the blocking member 220 may be detached to increase a seating space of the seat part 240, making it suitable for older children or adults. It should be understood that the child chair 200 according to the present disclosure may also be other types of chairs suitable for children.

    [0066] As shown in FIG. 1 to FIG. 4, the tray 100 is configured to detachably mount to the armrest 210 of the child chair 200. A main body of the armrest 210 extends substantially along the transverse direction of the child chair 200, while the tray 100 is detachably engaged with the armrest 210 along a height direction (up-down direction) to establish connection between the tray 100 and the child chair 200.

    [0067] In some embodiments, the tray 100 includes a tray body 110 which forms a main structure of the tray. An upper surface of the tray body 110 may be used for placing tableware or directly holding food, and may also serve for storing other items thereon. The tray body 110 is provided with a tray side wall 113, and a main body of the tray side wall 113 substantially extends along the transverse direction of the child chair 200. The tray side wall 113 is adapted to cooperate with a rear side wall 210B of the armrest 210. The tray side wall 113 keeps constant contact with the rear side wall 210B during the engagement process between the tray 100 and the armrest 210.

    [0068] The tray 100 further includes an engaging member 130, which is movably connected to the tray body 110. Specifically, the engaging member 130 may be movably connected to the tray body 110 along the longitudinal direction. The engaging member 130 is positioned in front of the tray side wall 113 along the longitudinal direction, to form a clamping mechanism for the armrest 210 together with the tray side wall 113. Specifically, the engaging member 130 and the tray side wall 113 form an engagement space 114. When it is required to connect the tray 100 to the armrest 210, the engagement space 114 of the tray 100 is aligned with the armrest 210 in the height direction, so that the tray side wall 113 abuts against the rear side wall 210B of the armrest 210, and the engaging member 130 abuts against the front side wall 210A of the armrest 210. By applying downward pressure to the tray 100 (or merely by means of self-weight of the tray 100 itself), the armrest 210 slides into the engagement space 114, and the engaging member 130 eventually reaches an engaged position, to complete the connection between the tray 100 and the armrest 210. The engaging member 130 may also be disengaged from the engaged position to reach a disengaged position, thereby allowing the tray 100 to be removed from the armrest 210.

    [0069] As shown in FIG. 4, when the engaging member 130 abuts against the front side wall 210A of the armrest 210 in the longitudinal direction, a dimension of the engagement space 114 is equivalent to a dimension of the armrest 210, so that the armrest 210 is fastened into the engagement space 114, thereby ensuring that the tray 100 remains stationary relative to the armrest 210. When the engaging member 130 moves away from the front side wall 210A of the armrest 210 in the longitudinal direction (as shown in FIG. 8(a) and FIG. 9(d)), the armrest 210 may be conveniently inserted into or removed from the engagement space 114.

    [0070] Specifically, the engaging member 130 may include a first engagement hook 132. As shown in FIG. 4, FIG. 7, and FIG. 11, the engaging member 130 includes an engaging member body 133, a lower end of the engaging member body 133 extends rearward and bends upward to form a first engagement hook 132. However, it should be understood that the first engagement hook 132 may also be formed in other ways. For example, the first engagement hook 132 may be a separately formed hook structure fixed to the engaging member body 133.

    [0071] Corresponding to the first engagement hook 132, the armrest 210 is provided with an armrest engaging slot 212 that may be engaged with the first engagement hook 132. In the embodiments shown in FIG. 4 and FIG. 10, the armrest engaging slot 212 is disposed behind the front side wall 210A of the armrest 210 transversely extending and opens downward. Nevertheless, it should be noted that the armrest engaging slot 212 may alternatively be configured in other forms. For example, the armrest engaging slot 212 may be another hook disposed on the front side wall 210A of the armrest 210 and capable of being engaged with the first engagement hook 132.

    [0072] When the engaging member 130 is in the engaged position as shown in FIG. 4, the first engagement hook 132 is engaged with the armrest engaging slot 212 on the armrest 210 of the child chair 200, thereby ensuring that the tray body 110 is locked to the armrest 210 of the child chair 200. This can effectively prevent the tray 100 from wobbling vertically or being disengaged upward.

    [0073] On the other aspect, as shown in FIG. 9(b), when the engaging member 130 is disengaged from the engaged position (i.e., the engaging member 130 is in the disengaged position), the first engagement hook 132 is not engaged with the armrest engaging slot 212 on the armrest 210 of the child chair 200, so that the tray 100 may be separated from the child chair 200.

    [0074] In one embodiment, the first engagement hook 132 may be provided with an engaging member inclined surface 132A (see FIG. 7 and FIG. 11). During insertion of the armrest 210 into the engagement space 114 in the height direction, the engaging member inclined surface 132A facilitates the engagement between the first engagement hook 132 and the armrest engaging slot 212. Optionally, the lower end of the front side wall 210A of the armrest 210 is provided with a rounded face. Similarly, the rounded face facilitates the engagement between the first engagement hook 132 and the armrest engaging slot 212 during the connection of the tray 100 to the armrest 210. Further optionally, an upper end of the front side wall 210A of the armrest 210 may be also provided with a rounded face. The rounded face may facilitate the engaging member 130 to slide downward along the front side wall 210A of the armrest until it reaches the engaged position.

    [0075] Certainly, a mating structure between the engaging member 130 and the armrest 210 according to the present disclosure is not limited thereto. In another embodiment, the engaging member 130 may be provided with an engaging slot, while the armrest 210 may be provided with an engagement hook. In yet another embodiment, the engaging member 130 and the armrest 210 may employ other matching structures, such as engaging pins and engaging holes, respectively.

    [0076] To ensure the stable engagement between the first engagement hook 132 and the armrest engaging slot 212, and to prevent the tray 100 from falling off due to the accidental disengagement between them, the tray 100 may further include a second reset member (for example, an engaging member reset elastic member) 150, which tends to make the engaging member 130 move to and keep in the engaged position. The second reset member 150 may be in the form of a spring, a leaf spring, a pneumatic rod, or a hydraulic rod, among other types of elastic members.

    [0077] In the embodiments shown in FIG. 7 and FIG. 11, the second reset member 150 is an elastic rib disposed at a lower end of the engaging member 130, which constantly urges the engaging member 130 to move upward. For example, the number of the elastic rib is two, and two elastic ribs form a splayed structure. The elastic rib 150 may have other suitable shapes, as long as it may prompt the engaging member 130 to reset. The elastic rib 150 has a simple structure and does not require a separate spring or other reset members, thereby saving costs.

    [0078] In addition, the tray 100 may include a first reset member (for example, a longitudinal reset elastic member) 140, which tends to make the engaging member body 133 abut against the front side wall 210A of the armrest 210 in the longitudinal direction. The first reset member 140 may act directly on the engaging member body 133, or may indirectly apply elastic force to the engaging member body 133 through other intermediate components.

    [0079] In some embodiments, to facilitate the user's operation of moving the engaging member 130 between the engaged position and the disengaged position, the present disclosure also provides a driving seat 120 that is movably linked with the engaging member 130. This allows a user to drive the movement of the engaging member 130 between the engaged position and the disengaged position by operating the driving seat 120. However, it should be understood that the driving seat 120 is not a necessary component to the tray 100 according to the present disclosure. The user may directly contact and move the engaging member 130 without the driving seat 120. In the embodiments shown in FIG. 6 and FIG. 7, the tray body 110 is formed by a tray upper cover 111 and a tray lower cover 112. A shell formed by the tray upper cover 111 and the tray lower cover 112 encloses a major portion of the driving seat 120 and the first reset member 140, which makes the tray 100 to get a neater appearance. Of course, the tray body 110 may also be a structure with only a single cover, and the driving seat 120 and the first reset member 140 may be disposed at a lower part of this single cover.

    [0080] In the embodiments shown in FIG. 4, FIG. 6, and FIG. 7, the driving seat 120 is movably connected between the tray body 110 and the engaging member 130, and is movable between a locked position and an unlocked position relative to the tray body 110.

    [0081] Furthermore, the engaging member 130 is movably connected to the driving seat 120. The driving seat 120 is configured such that the movement of the driving seat 120 relative to the tray body 110 may drive the engaging member 130 to move between the engaged position and the disengaged position. More specifically, the driving seat 120 and the engaging member 130 are arranged in such a way that the movement of the driving seat 120 towards the locked position may drive the engaging member 130 to the engaged position, and the movement of the driving seat 120 towards the unlocked position may drive the engaging member 130 to the disengaged position.

    [0082] As shown in FIG. 6 and FIG. 7, a major portion of the driving seat 120 has a flat shape, so that the driving seat 120 may move longitudinally between the tray upper cover 111 and the tray lower cover 112. Of course, the driving seat 120 may be in other shapes, such as a block, and may be disposed at other locations, such as the lower part of the tray body 110.

    [0083] To facilitate the user's operation of the driving seat 120, in the embodiments shown in FIG. 6, FIG. 7, and FIG. 12, the driving seat 120 is provided with an operating member 124. By pulling the operating member 124 with a finger, the user may move the driving seat 120. For example, in the embodiment shown in FIG. 6, the user may move the driving seat 124 in a direction towards the unlocked position (i.e., a direction indicated by an arrow D1 in FIG. 6) by operating the operating member 124. Certainly, the user may also move the driving seat 124 in a direction towards the locked position (i.e., a direction opposite to that indicated by the arrow D1 in FIG. 6) by operating the operating member 124. In the embodiments shown in FIG. 6 and FIG. 7, the operating member 124 is shown as a pulling slot on the driving seat 120. However, in other embodiments, the operating member 124 may be a lever or a protrusion for operation.

    [0084] At a position corresponding to the operating member 124, the tray lower cover 112 may have a through-hole to allow the user to access the operating member 124, or to permit the operating member 124 to extend outside the tray lower cover 112.

    [0085] To facilitate mounting the tray 100 onto the armrest 210, the driving seat 120 may be provided with a second engagement hook 123 (see FIG. 7), which may be engaged with a limiting step 211 on the armrest 210 of the child chair 200 (see FIG. 10) to further enhance the connection stability between the armrest 210 of the child chair 200 and the tray 100.

    [0086] Furthermore, as shown in FIG. 7, the driving seat 120 is provided with an inclined sliding slot 121 (see FIG. 12) that is inclined to a movement direction of the driving seat 120, and the engaging member 130 has a sliding protrusion 131 that may be slidable within the inclined sliding slot 121 (see FIG. 11). The cooperation between the sliding protrusion 131 and the inclined sliding slot 121 allows the movement of the driving seat 120 in the longitudinal direction relative to the tray body 110 to drive the engaging member 130 to move between the engaged position and the disengaged position.

    [0087] Specifically, when the driving seat 120 and the inclined sliding slot 121 provided on the driving seat 120 move longitudinally, the sliding protrusion 131 of the engaging member 130 is subjected to a force from the inclined sliding slot 121. A direction of this force is perpendicular to an extension direction of the inclined sliding slot 121, so this force has components in both the longitudinal and vertical (height) directions. When the user operates the driving seat 120 to move in the direction indicated by an arrow D1 in FIG. 6, due to limiting action between the first engagement hook 132 of the engaging member 130 and the armrest engaging slot 212 on the armrest 210, the engaging member 130 may not move longitudinally, or, the component of the aforementioned force in the longitudinal direction is canceled out by the first engagement hook 132 and the engaging slot 212. The component of the force in the vertical direction may drive the sliding protrusion 131 and the engaging member 130 to move vertically. Specifically, the engaging member 130 may move downward relative to the driving seat 120 in the direction indicated by an arrow D2 in FIG. 6, thereby reaching the disengaged position. Since the engaging member 130 has reached the disengaged position, the first engagement hook 132 is disengaged from the engaging slot 212, no longer providing a limiting action on the engaging member 130. Continuing to pull the driving seat 120 in the direction indicated by the arrow D1 in FIG. 6, the engaging member 130 may also move in the direction indicated by the arrow D1, and due to the action of the second reset member 150, the engaging member 130 may also move upward.

    [0088] The cooperation between the inclined sliding slot 121 and the sliding protrusion 131 not only allows the driving seat 120 and the engaging member 130 to interact with each other, but also enables the movement of the driving seat 120 to drive the engaging member 130 to move in different directions, thus allowing for more flexible arrangement of the driving seat 120 and the engaging member 130.

    [0089] In the embodiments shown in FIG. 7 and FIG. 12, an end of the driving seat 120 may be provided with a receiving recess 125, in which the engaging member 130 is movably disposed. The second reset member 150 abuts against a bottom wall of the receiving recess 125 to provide a resetting force for the upward movement of the engaging member 130. In this embodiment, the inclined sliding slot 121 may be disposed on the inner side wall of the receiving recess 125 to cooperate with the sliding protrusion 131 of the engaging member 130. This structure not only can prevent the engaging member 130 from slipping out of position, but also facilitate the movable connection between the engaging member 130 and the driving seat 120.

    [0090] Certainly, the present disclosure is not limited thereto. In another embodiment, the engaging member 130 may be provided with an inclined sliding slot, and the driving seat 120 may be provided with a sliding protrusion that slides within the inclined sliding slot.

    [0091] In other embodiments, the driving seat 120 and the engaging member 130 may be interactively linked through other cooperative structures. For example, the driving seat 120 and the engaging member 130 may be spaced apart, and the driving seat 120 using a traction member to drive the engaging member 130.

    [0092] To facilitate the user's operation of the driving seat 120, the first reset member 140 tends to move the driving seat 120 towards the locked position, thereby driving the engaging member body 133 to abut against the front side wall 210A of the armrest 210 in the longitudinal direction.

    [0093] The first reset member 140 may also be in the form of a spring, a pneumatic rod, or a hydraulic rod, or other types of elastic members.

    [0094] In the embodiments shown in FIG. 6 and FIG. 7, the first reset member 140 is a tension spring, which tends to move the driving seat 120 in a direction opposite to that indicated by the arrow D1 in FIG. 6. The spring is a standard component, which has a simple structure, low procurement cost, and is convenient installation and fixing, and provides good resetting performance.

    [0095] As shown in FIG. 7 and FIG. 12, the driving seat 120 may be provide with a reset member mounting slot 122, in which the first reset member 140 is mounted. The reset member mounting slot 122 may guide and restrict a stretching direction of the first reset member 140. One end of the first reset member 140 abuts against the driving seat 120, while the other end of the first reset member 140 passes through the reset member mounting slot 122 to abut against the tray body 110, so that the driving seat 120 has a tendency to move towards the locked position.

    [0096] Hereinafter, the operation process of the engaging member 130 and the driving seat 120 according to the present disclosure will be described with reference to FIG. 8(a) to FIG. 8(d) and FIG. 9(a) to FIG. 9(d).

    [0097] FIG. 8(a) to FIG. 8(d) illustrate a process of engaging the engaging member 130 of the tray 100 with the armrest 210 of the child chair 200 according to the present disclosure.

    [0098] When it is required to connect the tray 100 to the armrest 210 of the child chair 200, the tray side wall 113 of the tray 100 first abuts against an upper edge of the rear side wall 210B of the armrest 210, and the first engagement hook 132 of the engaging member 130 abuts against an upper edge of the front side wall 210A of the armrest, so that the engagement space 114 is aligned with the armrest 210. At this time, the first reset member 140 is in a compressed state. Then, the tray 100 is pressed downward (or simply by the weight of the tray 100 itself), causing the tray side wall 113 to move downward along the rear side wall 210B of the armrest, and the first engagement hook 132 to move downward along the front side wall 210A of the armrest. When the tray 100 moves downward to the position shown in FIG. 8(a), the tray side wall 113 abuts against the rear side wall 210B of the armrest 210, and the first engagement hook 132 of the engaging member 130 is positioned at a lower edge of the front side wall 210A of the armrest 210.

    [0099] The tray 100 continues to move downward. Due to the elastic force of the first reset member 140 and the self-weight of the tray 100, the engaging member 130 moves downward by overcoming the elastic force of the second reset member 150. The driving seat 120 moves toward the locked position (i.e., leftward in FIG. 8(a)), thereby driving the connected engaging member 130 to also move leftward in FIG. 8(a). The first engagement hook 132 may pass over the lower end of the front side wall 210A of the armrest, reaching the position shown in FIG. 8(b).

    [0100] Due to the elastic force of the first reset member 140, the driving seat 120 and the engaging member 130 continue to move leftward in FIG. 8(b). When the engaging member 130 moves to the position where the engaging member body 133 abuts against the front side wall 210A of the armrest 210, the first engagement hook 132 precisely moves below the armrest engaging slot 212 of the armrest 210, as shown in FIG. 8(c).

    [0101] Subsequently, although the engaging member 130 cannot continue to move leftward in FIG. 8(c) because of abutting against the front side wall 210A of the armrest 210, the leftward movement of the driving seat 120 in FIG. 8(c) drives the engaging member 130 upward through the interaction between the inclined sliding slot 121 of the driving seat 120 and the sliding protrusion 131 of the engaging member 130. At the same time, the second reset member 150 also drives the engaging member 130 to move upward. When the driving seat 120 reaches the locked position, the first engagement hook 132 of the engaging member 130 is engaged with the armrest engaging slot 212, and the engaging member 130 reaches the engaged position, as shown in FIG. 8(d). As a result, on one hand, the engaging member 130 tightly adheres to the front side wall 210A of the armrest 210, preventing the tray 100 from wobbling up and down; on the other hand, the engagement of the first engagement hook 132 of the engaging member 130 with the armrest engaging slot 212 of the armrest 210 prevents the tray 100 from falling off upwards, thereby locking the tray 100 relative to the armrest 210 to keep stationary. In addition, the tray side wall 113 and the engaging member body 133 may abut against the rear side wall 210B and the front side wall 210A of the armrest, respectively, so that the tray 100 may keep stationary longitudinally relative to the armrest 210.

    [0102] FIG. 9(a) to FIG. 9(d) illustrate a process of disengaging the engaging member 130 of the tray 100 from the armrest 210 of the child chair 200 according to the present disclosure.

    [0103] As shown in FIG. 9(a), the first engagement hook 132 of the engaging member 130 is engaged with the armrest engaging slot 212 of the armrest 210. At this time, the driving seat 120 is in the locked position, and the engaging member 130 is in the engaged position.

    [0104] Under the operation of the user, the driving seat 120 moves longitudinally towards the unlocked position (i.e., rightward in FIG. 9(a)). At the same time, the movement of the driving seat 120 drives the engaging member 130 through the interaction between the inclined sliding slot 121 of the driving seat 120 and the sliding protrusion 131 of the engaging member 130. As a result, the engaging member 130 moves downward by overcoming the elastic force of the second reset member 150. When the first engagement hook 132 of the engaging member 130 is disengaged from the armrest engaging slot 212 of the armrest 210, the engaging member 130 reaches the disengaged position, as shown in FIG. 9(b), and the driving seat 120 reaches the unlocked position.

    [0105] Under the continued operation of the user, the driving seat 120 continues to move rightward in FIG. 9(b), causing the engaging member 130 connected with the driving seat 120 to also move rightward in FIG. 9(b). During this process, the first engagement hook 132 of the engaging member 130 abuts against the lower surface of the front side wall 210A of the armrest 210, as shown in FIG. 9(c).

    [0106] Under the operation of the user, the engaging member 130 continues to move rightward in FIG. 9(c) along with the driving seat 120, until the first engagement hook 132 of the engaging member 130 is disengaged from the lower surface of the armrest 210. Subsequently, through the interaction between the sliding protrusion 131 of the engaging member 130 and the inclined sliding slot 121 of the driving seat 120, the engaging member 130 moves upward while moving rightward and closer to the driving seat 120. Additionally, under the elastic force of the second reset member 150, the engaging member 130 may also move upward, reaching the position shown in FIG. 9(d). In this way, the tray 100 may be removed from the armrest 210 of the child chair 200.

    [0107] Since the features of the present disclosure may be embodied in various forms without departing from its characteristics, it should be understood that the above-described embodiments are not limited by any details described above, unless otherwise specified, but should be construed broadly within the scope defined by the pending claims. Accordingly, all modifications and variations falling within the scope of the claims or equivalents thereof shall be covered by the pending claims.
