Description

Detachable breastplate {DETACHABLE CHEST SUPPORTER FOR CHAIR}

The present invention relates to a breastrest that is detachably installed on a chair back, and more particularly, to increase portability by attaching and detachable to the rear of the chair back. When the breastrest is to be used, the chair can be used without interference from the surrounding environment. It relates to a detachable breastrest capable of supporting the chest portion by rotating the cushion from the rear to the front.

It is not an exaggeration to say that most of the day of students or office workers living in a chair is not an exaggeration. Most people, not just those of the above-mentioned categories, live their lives and sit on chairs for at least 20 years. In some cases, in particular, depending on the job type, you may have to sit in a chair and work your entire life.

Moreover, in recent years, unlike in the past, when there was a lot of outside activities due to high school fever and long computer use, the spine and pelvis are twisted, unlike in the past.In particular, most children's body types become unbalanced before puberty 10 It starts around three years old, and research shows that it can be severe in female students, and this imbalance continues to progress while they are tall.Therefore, if children's unbalanced body shape is not initially managed, it can affect developmental growth and even after adulthood. You will not be able to have a straight and beautiful body.

As such, as the chair is very close to human life, the effect of the sitting posture on the body will be great, and if the posture is not correct as mentioned above, it will easily get tired and cause body pain such as stiff shoulders. If bad posture is habituated, it may lead to body imbalance, such as spinal deformity.

Accordingly, recently, chairs have been developed to prevent deformities of the spine due to an incorrect sitting posture, and most of these posture correction or body shape correction chairs focus on the backrest structure that supports the user's back.

However, a chair that has a backrest structure and has a characteristic structure may be able to reap effects such as posture correction when the occupant is completely leaning against the backrest.

Looking at the usage behavior of users sitting on a chair and doing work, most of the users maintain a state with their upper body slightly tilted forward, but in such a state of use, there is a limitation that it is not possible to correct posture or correct body shape.

In particular, if the upper body is held forward for a long period of time, all the loads are concentrated on the lower back, making it easier to feel fatigue, and the incorrect posture can also cause scoliosis.

In order to solve the above problems, conventionally, Patent Publication No. 10-2010-0093862 (2010.08.26.) 『Feedback Chair』, Registered Utility Model No. 20-0172039 (1999.12.08.) 『Posture Correction Chair. ', and Patent Publication No. 10-2001-0018174 (2001.03.05.) "Multifunctional chairs" have been proposed to have a structure capable of supporting the chest area.

However, first of all, in Korean Patent Publication No. 10-2001-0018174, a specific operation method or structure for the fly part was simply disclosed, rather than a specific operation method or structure, etc., and Utility Model No. 20-0172039 discloses the fly part. , As it is formed in a structure that rotates upward from the front of the seat part where the user is seated, it is disadvantageous to use when the user is wearing a skirt, and the body shape is different for each person seated in the chair. It cannot be controlled properly, which causes inconvenience in use.

In addition, Patent Application Publication No. 10-2010-0093862 has a structure that can rotate the breastplate itself to the side, so that when a user sits and stands on the seat, there is no interference caused by the breastrest. Although it was designed to be more convenient to use than 0172039, in the case of Korean Patent Application Publication No. 10-2010-0093862, the user pulls the breastrest rotated at a certain angle while sitting on the seat to the side of the user. It must be rotated, but it is a structure that cannot be applied in the case of a chair with armrests. In order to rotate to the side of the chair, a free space must be secured with a certain radius on the side so as not to interfere with other objects to the side, but there is a problem that can be used .

Moreover, referring to the above-mentioned conventional technologies, the structure is fixed and installed at the time of production of the chair, and cannot be applied by attaching and detaching it to a general chair. In addition, it is not possible to precisely adjust the user's chest when seated. Products on the market that do not support the part are generally supported by the lower abdomen of the chest, so that the intended purpose cannot be achieved.

Therefore, it overcomes the irrationality of the conventional breastrest chair and is easily detachably fixed to the chair with a backrest, and only when the breastrest is used, it rotates without interference from the surrounding environment, so that it can be accurately positioned on the chest of the user through precise manipulation. There is a growing demand for a detachable breastplate that allows it to be used.

In the direction, the fixing hole 12 is cut and formed with the same length on the same height line as the installation hole 11.

The fixing bar 20 is inserted into the installation hole 11, and the first rotating member 30 is placed on the chair at a predetermined height at which the cushion pad 50 will be located and the side of the fixing bar 20. In consideration of a certain position to be rotated without interference, it is moved to the left and right and in the vertical direction, and then the fixing bolt is inserted into the fixing hole 12 so as to be pressed and fastened to the outer edge of the fixing bar 20.

The first rotation member 30 has one end coupled to one end of the fixing bar 20 and rotates to the side of the chair back with the longitudinal direction of the fixing bar 20 as an axial direction. This first rotating member 30 is to prevent the user from interfering with the seating of the chair by tilting the back of the chair when the breastrest is not normally used, and the user can use the first rotating member 30 only when the breastrest is to be used. Rotate to use.

In addition, the first rotating member 30 further includes an interference preventing portion 31 formed in a convexly bent central portion along the longitudinal direction. As shown in the drawing, the interference preventing unit 31 is convexly raised due to the inclined surface 31a inclined so that both sides face each other in the longitudinal direction of the first rotating member 30, and the both ends thereof are inclined surfaces. Including the raised surface 31b connected to (31a), when the first rotating member 30 is rotated in front of the back of the chair, the shoulder of the user seated in the chair is the raised surface of the interference preventing unit 31 ( 31b) It is positioned inward so that the user's shoulder portion does not collide with the first rotating member 30.

Moreover, the raised surface 31b of the interference preventing part 31 is variable in length so that the position can be adjusted in the front-rear direction to suit the user's shoulder position.

The second rotating member 40 has one end rotatably coupled to the other end of the first rotating member 30 so that the longitudinal direction of the first rotating member 30 is axially directed from the outside of the chair back to the inner surface. Is rotated.

The cushion pad 50 is coupled to the other end of the second rotating member 40, but in the present invention, it is rotatably coupled in the axial direction in a direction perpendicular to the longitudinal direction of the second rotating member 40, and is folded in a normal state. When the first rotation member 30 is rotated to use the breastrest while maintaining it, it is unfolded and positioned in the same longitudinal direction as the second rotation member 40.

That is, when the cushion pad 50 is not used, the first rotating member 30 and the cushion pad 50 coupled to both ends of the second rotating member 40 are separated by the length of the second rotating member 40. So that they are folded side by side and in the same direction. The operation and usage of the cushion pad 50 will be described in more detail in the usage of the breastrest to be described later.

Moreover, a chinrest 60 on which a seating jaw of an inwardly curved shape is formed is further coupled to one side of the cushion pad 50, so that the chest and chin of the person seated in the chair are the cushion pad 50 and the chinrest ( 60). In addition, such a chin rest 60 is built into one side of the cushion pad 50, but is rotatably installed so that when the user needs the chin rest 60, it is pulled from the inside of the cushion pad 50 to prevent the user's chin and You can also use it by adjusting the distance of.
