Definitions

  • the present invention relates to a pelvis protecting chair. More specifically, it is about comprising the seat which is in contact with the user's pelvis with elastic materials so that it should protect the pelvis.
  • human spine is formed with the cervical vertebrae, the thoracic vertebrae, and the lumbar.
  • the coccyx located at the end of the lumbar, can be the origin of pain due to overwork or sedentariness, and this pain is called coccygodinia.
  • coccygodinia is a disease which brings pain when the coccyx, located behind the anus, moves and the coccyx individually is not the cause of the disease.
  • the disease occurs twice more to women than to men, and it is usually diagnosed to factory workers or secretaries.
  • Skeletal muscle relaxants can be used for treating this disease, if this treatment does not bring any progress, local anesthetize or injecting steroids can help to bring relaxation to the muscles connected to the coccyx. The patient should work out the muscles at his lower back, and he should also fix his wrong posture.
  • hemorrhoids is a varix in the rectum and the anus, in other words, it is the expanded vain of the anus and lower rectum.
  • Hemorrhoids can be classified as internal hemorrhoids and external hemorrhoids develops around the anus and is surrounded with very sensitive tissues, and if thrombus develops, extreme bloat erupts with severe pain. It can be detected as a hard lump and when it is ruptures, it bleeds.
  • Korean Utility Model Reg. No. 20-0260631 The conception of Korean Utility Model Reg. No. 20-0260631 is to manually adjust the space between the two seats, using a set of linkages mounted under the chair.
  • the chair is used by a single user so that once the space between the seats, there is no necessary to adjust it again, which leads to the increase of the manufacturing cost.
  • this invention contrives from the described problems that has a purpose of developing a coccyx protecting chair, which considers the users physical status and can adjust the space between a set of seats to a certain amount, and allow vertical adjustments of the seats.
  • Another object of this invention is to simplify the frame of the chair which improves the manufacturing.
  • this invention has at least one set of base hinges mounted symmetrically on the upper base plate, a base mounted on the stationary part securing the default height of the chair, at least a single seat support which is hinged to the aforementioned base, a spring which is mounted between the aforementioned base and the seat base to sustain the resilient between the two bases, and a pair of seats corresponding to the two seat bases.
  • the support hinge of the seat support is mounted on the side of the aforementioned base to behave as a stopper which sustains the seat support at a uniform angle.
  • the aforementioned spring is a leaf spring which has one end of the spring mounted to the topside of the base, and the other end which is upper curved so that it can absorb the compression from extreme stress, mounted to the bottom side of the seat support.
  • the leaf bottom side of the spring is fixed to the seat support.
  • the base, or the stationary part has a set of armset connected to the lower part of it, and it also has a backboard attached to it.
  • the stationary part also includes a height adjustment linkage, and a caster for making the vertical movement possible.
  • the invention prevents widening of the pelvis for users who are in a sedentary position for long times, and reduces the pressure on the coccyx so that the pain to the coccyx can be relieved, and provides convenience to patients of anal diseases.
  • This invention also increases productivity due to its relatively simple design.
  • FIG. 1 is the structural front view of the Pelvis Protecting Chair.
  • FIG. 2 is the descriptive front view of the Pelvis Protecting Chair.
  • FIG. 3 is the structural plane view (A) and the side view (B) of the seat.
  • FIG. 4 is the structural front view of the seat.
  • FIG. 5 is the descriptive plane view (A), side view (B), front view (C) of the base of the seat.
  • FIG. 6 is the structural plane view (A), side view (B), front view (C) of the base of the seat.
  • FIG. 7 is the structural plane view (A), side view (B), front view (C) of the leaf spring.
  • FIG. 8 is the disassembly figure of the components which constructs the main part of the Pelvis Protecting Chair.
  • the Pelvis Protecting Chair is consists of a base ( 10 ) mounted on a stationary part ( 65 ) which has a caster ( 66 ) mounted on a stand ( 65 ), two seat supports ( 20 ) hinged to the base, a leaf spring ( 30 ) to provide elasticity between the seat and the base, seats ( 50 ) mounted on the seat supports ( 20 ), and two armrests ( 75 ) and a backboard which are both connected to the base ( 10 ).
  • the connecting part ( 11 a ) is used as the gap for bolt which goes through the screw hole ( 11 b ), and the curved end ( 35 ) of the leaf spring ( 30 ) insures the space for lowering the seat.
  • the base plate ( 11 ) is a 2 mm thick steel plate for light weight, and for rigidity, the edge of the plate is tilted toward the down side. It is pressed so that the center of the plate is projected in the horizontal direction (in the direction of the hinges ( 13 )).
  • the seat support ( 20 ) is connected with the base ( 10 ) with 4 hinges ( 13 ).
  • the support hinge ( 23 ) connected to the base hinge ( 13 ), is formed downward, and there is the seat instillation ( 21 ) mounted on the seat ( 50 ).
  • the supporting hinge ( 23 ) has the second connecting hole ( 23 a ) which corresponds to the first connecting hole ( 13 a ) of the base hinge ( 13 ), and there is a stopper ( 23 b ) on the edge side of the base ( 10 ).
  • the spring ( 30 ) consists a curved mid section ( 33 ) at the point where the seat support ( 20 ) hinge is linked, and centering around the mid section ( 33 ), the upper part ( 32 ) which is in contact to seat support ( 20 ), and the stationary stage ( 34 ) which is connected to the upper curved spring of the seat support ( 20 ) is positioned. And centering the mid section ( 33 ) the lower stage ( 31 ) connected to the upper part of the base ( 10 ), and the curved section ( 35 ) which is tilted upward is symmetrically positioned. This curved section ( 35 ) absorbs the impact from extreme weight acting downward.
  • the main components of seat according to this invention are connected as shown in FIG. 3 and FIG. 4 .
  • the seat support hinge ( 23 ) of the seat support ( 20 ) is connected to the base hinge ( 13 ) of the base ( 10 ), and the hinge bolt ( 40 ) is used to connect the hinges.
  • the spring ( 30 ) Before connecting the hinge bolt ( 40 ), the spring ( 30 ) should be compressed to be set up between the base ( 10 ) and the seat support ( 20 ), and then the hinge bolt ( 40 ) should be tightened.
  • the seat ( 50 ) should be fixed to the seat support ( 20 ) with the seat bolt ( 55 )
  • the stationary part ( 60 ) connected to the stand ( 65 ) can be connected to the base ( 10 ) and the base can also be connected to the stationary part ( 60 ), and the armrests ( 75 ), and the backboard ( 70 ), when necessary.
  • the space between the seat support ( 20 ) and the base ( 10 ) sustains a certain amount of distance due to the tension of the leaf spring ( 30 ) which results to a parallel state.
  • the repulsion of the spring ( 30 ) prevents the seat support ( 20 ) from being unparallel and moving up, by making one side of the stopper ( 23 b ) at the hinge ( 23 ) to be in contact with the side of the base ( 10 ).
  • This invention prevents the pelvis of the patient from becoming wider, and relieves the pressure of the coccyx to constraint the pain, and provides convenience to patients with anal diseases.
