Description

high chair

technical field

The utility model relates to a high chair for children, in particular to a high chair with an adjustable dinner plate.

Background technique

Most of the tables and chairs used for dining are designed for adults, and are not suitable for children who are much smaller than adults. In order to provide tables and chairs for children to eat, and to facilitate feeding and care for their caregivers, a high chair with a dining plate was developed to increase the height of the child when sitting to be equivalent to an adult, and it is attached to the high chair. The dinner tray on the chair can be used to place children's tableware.

In order to suit children of different sizes and facilitate children to sit or leave the seat, most of the dinner plates are designed to be able to adjust their position, especially to move back and forth along the direction of the armrest, so that the dinner plate can be closer to the back of the chair or farther away from the back of the chair, so as to Provide suitable space for children.

The existing methods for adjusting the position of the dinner plate, such as adopting a push-pull method or using two buttons to control the release structure of the dinner plate, are often inconvenient in operation. Therefore, there is still a need for a plate adjustment mechanism that can easily adjust the position of the plate of the high chair and can be operated simply.

The specific connection mode between the linkage arm 413 and the first end 421 is described as follows: each plate locking member 41 also has a boss 415 located at the end of the linkage arm 413, and the first cam portion 423 of the pull rod 42 It is defined by an oblique cam groove 423, and the cam groove 423 can cooperate with the boss 414 to limit the displacement distance of the unlocking of the plate locking member 41, that is, when the boss 414 is in the When the end of the cam groove 423 away from the second end 422 can make the plate locking member 41 move relative to the pull rod 42, the two locking members 41 can be moved closer to each other, thereby making the engaging protrusion 412 disengages from the engaging hole 221 of the armrest 22 . The dinner plate adjustment mechanism 4 also includes two first return elastic members 44 that can provide the restoring force of the dinner plate locking member 41, and each first return elastic member 44 is separately arranged on each of the dinner plate locking members 41 and the lower plate body. portion 31, and constantly biases the plate locking member 41 toward the locked position. In this embodiment, each first return elastic member 44 is a linear spring, and each plate locking member 41 also has an extension portion 416 extending from the second frame side portion 4112 to the opposite direction of the linkage arm 413, the first The return elastic member 44 is accommodated in the extension part 416, and one end adjacent to the second frame side part 4112 is against the rib 315 on the lower plate body 31. When the plate locking member 41 moves from the locking position to the release position, When the locking position, the first reset elastic member 44 is compressed to generate a restoring force, when the external force applied to the plate locking member 41 (the external force pulled by the pull rod 42 to pull the linkage arm 413 ) is removed, the The restoring force of the elastic member 44 is reset, so that the plate locking member 41 returns to the locked position from the unlocked position.

The control button 43 also has a frame wall 432 and two engaging ribs 433 . The two engaging ribs 433 respectively protrude from two sides of the frame wall 432 . The lower plate body 31 is provided with a groove 319 (see FIG. 4 ) for accommodating the control button 43, so that the control button 43 can pass through the lower side of the lower plate body 31, which is convenient for the user to operate. A side wall 316 is formed on the side, and the side wall 316 is provided with engaging grooves 317 for accommodating corresponding engaging ribs 433 respectively. The engaging ribs 433 can move up and down along the engaging grooves 317 . By pressing the control button 43 from bottom to top, the second end 422 of the pull rod 42 can slide along the second cam portion 431 to generate a displacement, and at the same time, the pair of dinner plate locking members 41 can move along the first cam portion 423 of the pull rod. Displacement, so as to drive the plate locking member 41 to be located at the unlocking position, and make the engaging protrusion 412 disengage from the engaging hole 221 . The dinner plate adjusting mechanism 4 also includes a second return elastic member 45 that can provide the restoring force of the pull rod 42 . The second return elastic member 45 is disposed between the pull rod 42 and the lower plate body 31 to provide the return elasticity of the pull rod 42 . In this embodiment, the second return elastic member 45 is also a linear spring, the second return elastic member 45 is located in the pull rod 42, and one end is fixed to the boss 424 of the pull rod 42, and the other end is fixed to the bottom plate body 31. Protruding column 318 , and the second reset elastic member 45 is disposed between the pull rod 42 and the lower plate body 31 . When the control button 43 is pressed to move the second end 422 of the pull rod 42, and at the same time other parts of the pull rod 42 are relatively moved toward the control button 43, the second return elastic member 45 is compressed to generate a restoring force, and the second return force is generated by the second reset. The restoring force of the elastic part 45 makes the pull bar 42 return to its original position after the control button 43 is released, and the dinner plate locking member 41 also returns to its original position through the restoring force of the first elastic reset part 44, thereby releasing the control button. 43, so that the dinner plate locking member 41 returns to the locking position, and the engaging protrusion 412 can be selectively engaged in part of the engaging hole 221, so that the dinner plate assembly 3 can be adjusted to the desired position. Desired position to match specific child's usage needs.

In this embodiment, there are a plurality of engaging protrusions 412 on the locking member 41, but there may be only one, and the dial body 33 is detachably arranged on the upper disc body 32, which is convenient for users to clean. Therefore, the dinner plate assembly 3 may not include the dial body 33 . In addition, the pull rod 42 can also be extended outwards to directly control the pull rod 42 to be pulled forward, and the control button 43 can be replaced.

In summary, the plate locking mechanism 4 of the high chair 1 of the present invention can drive the pull rod 42 and the plate locking member 41 by pressing the control button 43 with one hand, so that the plate locking member 41 is positioned at the position of the unlocked position. position, that is, the dinner plate assembly 3 can be freely moved along the extension direction of the armrest 22. When adjusted to an appropriate position, the control button 43 is released to return the pull rod 42 and the dinner plate locking member 41 to their original positions, so that The dinner plate locking member 41 is locked on the armrest 22 again, that is, the dinner plate locking member 41 is located at the locked position, so that the dinner plate assembly 3 is positioned at a desired position relative to the armrest 22. Operate the control button 43 to move the dinner plate assembly 3 away from the armrest 22, and operate the position or removal of the dinner plate assembly 3 with one hand, which has the effect of simple and convenient operation.
