Background Art

A nap chair is a seat specially designed for naps or short breaks. It is widely used in offices, medical institutions, schools and other public places to provide employees, patients or students with a space to relax and rest. A nap chair usually has a comfortable cushion and an adjustable backrest to provide people with comfort and support during naps or breaks. A nap chair leg rest refers to a component on a nap chair used to support the legs. It is usually located at the front of the chair, allowing the user to place their legs on it when sitting down to rest, providing support and comfort. However, most of the nap chair leg rests in the prior art still have some problems that need to be solved during use.

In order to facilitate the storage of the chair and save space, most of the nap chairs in the prior art are generally designed to have leg rests that can be pulled out and put away. However, the use of most of the nap chair leg rests in the prior art is cumbersome. During a nap, the user needs to pull the leg rest out from the bottom of the nap chair for use, and then adjust the angle of the nap chair backrest to achieve a comfortable sleeping angle. The two cannot be performed at the same time, and adjusting them one by one requires extra time and effort, which reduces the convenience of use and results in a poor user experience.

Utility Model Content

The utility model aims to solve the shortcomings in the prior art and proposes a lunch break chair leg support with a pull-out and flip structure.

In order to achieve the above purpose, the utility model adopts the following technical solutions:

The two cams are connected at the same time by a toothed connection, and the two cams are connected at the same time by a toothed connection, and the toothed connection is connected at the same time by a toothed connection.

As a further solution of the utility model, the two first connecting rods are fixedly connected to the first connecting block on the side away from the first set of plates, the two first connecting blocks are rotatably connected to the second connecting block, and the two second connecting blocks are fixedly connected to the second connecting rod on the side away from the first connecting rod.

As a further solution of the utility model, the two gears are fixedly connected with a first I-shaped wheel on the side close to each other, and the two first I-shaped wheels are rotatably sleeved with an L-shaped sleeve plate.

As a further solution of the utility model, the two second connecting rods are fixedly connected to a second set of plates on a side away from the second connecting block, and the two second set of plates are rotatably provided with a second I-shaped wheel.

As a further solution of the utility model, the tops of the two L-shaped sleeves are fixedly connected to the same third mounting plate, the bottom of the third mounting plate is fixedly connected to the top of the third sleeve, and the third mounting plate is installed at the bottom of the seat of the nap chair.

As a further solution of the utility model, the two second I-shaped wheels are fixedly connected to the same backboard on the side close to each other, and the top two sides of the backboard are fixedly connected to the fourth mounting plates, and the two fourth mounting plates are installed on the backrest of the lunch break chair.

The beneficial effects of the utility model are:

The utility model adopts a technical means that the leg rest can be pulled out and flipped while adjusting the backrest of the lunch nap chair. After the backrest is adjusted, the leg rest will be fully extended and can be used. This effectively solves the problem that most of the leg rests of lunch nap chairs in the prior art mentioned in the background technology are cumbersome to use, the backrest and the leg rest cannot be adjusted at the same time, and the adjustment requires extra time and effort, which reduces the convenience of use and leads to a poor user experience. The utility model thus realizes the technical effect of easy adjustment, which can improve convenience and enhance the user experience.
