Definitions

  • This invention relates to a chair whose height can be adjusted to an 5 optimum standard height or level in relation to the height of desk and the stature of user.
  • the height of desk is normalized to desks for chil dren, for students and for adults, and the height of chair is adjusted to an optimum level 10 in accordance with the stature of user, so that the user can sit on a chair to perform his study and work with a comfortable posture.
  • the -existent chair is adapted to liftably insert a lifting strut or column fixed to the lower surface of seat plate into a supporting cylinder with a plurality of supporting legs attached, and to tighten up closely the tip of
  • the existent chair has a drawback in that the adjusting of the chair height is very complicated because adjusting of the chair height into an optimum level is difficult by the adjust of one time and is possible by the trying of many- times.
  • This object of the present invention is accomplished by a chair which liftably inserts the lifting strut fixed to the lower surface of a seat plate into the supporting cylinder with a plurality of supporting legs attached and fix the same by a setscrew threaded to the supporting cylinder, characterized by fixing and attaching the chair height lookup plate which engraves the standard desk height indications, the stature scale of user and the optimum standard height scale of chair related with the user's stature on said one side of supporting cylinder ; and attaching the scaled plate which engraves the chair height scale on one side of the circumferential surface of said lifting strut.
  • the indications of a standard desk height engraved to said chair height hookup plate are made in accordance with the use of desks, that is, desks for child ren, for stature scale is indicated by the range extending from the standard stature of children to that of adults while the optimum standard height scale of a chair is indicated by the optimum height scale related to the standard desk height and the user's stature.
  • a user can read the o ' ptimum standard chair height for his stature in the chair height hookup plate ; and then release the setscrew and lift the lifting strut against the supporting cylinder in such manner that match a scale corres- ponding to said read height in the chair height scale with the upper surface of supporting cylinder, to set the height of seat plate into an optimum height ; and thereafter fix the lifting strut by tightening up the setscrew, thereby adjusting the chair height into an optimum level conveniently.
  • Figure 1 is a front view of the chair adjustable to an optimum standard level, which is a preferred embodiment of the present invention.
  • Figure 2 is a perspective view illustrating explodedly the main portion of the present invention. . -
  • Figure 3 is the enlarged view of the chair height hookup plate.
  • Figure is the enlarged view of the chair height scale.
  • a chair 1 applying the prese invention, which inserts a lifting strut or column 5 fixed to the lower surface a seat plate into a supporting cylinder 2 with a plurality of supporting le attached, and tightens up a setscrew 7 with a handle : engaged threaded through a screw hole 6 defined in one side of the upper portion of supporti cylinder 2 to fix a lifting strut 5 with reference to the supporting cylinder
  • lifting strut 5 In said one side of lifting strut 5 is longitudinally defined the long slot engaging the tip of said setscrew 7 closely. Further, in said supporting legs are rolling wheels 1 0 for contacting with the bottom surface.
  • a hookup plate I I indicating t chair height which is engraved the indications of standard chair height 1 2, t stature scale of user 1 3 and the optimum height scale of chair 1 '-. related to t user's stature, is attached fixedly to one side of the circum ferential surface supporting cylinder 2.
  • Said chair height lookup plate is attached fixedly to the supporting cylin by a fixing rod 1 7, and the interior end of this fixing rod 1 7 is engaged to groove for anti-rotation 1 8 defined longitudinally in the lifting strut 5 throu the supporting cylinder 2, for preventing the lifting strut 5 from being rota with reference to the supporting cylinder 2.
  • Said the scaled plate 1 5 of chair height is preferrable attached by defining the attached groove 1 9 in the lifting strut 5 not to project more largely than the circumferential surface of lifting strut 5, and may be carved on the surface of attached groove 1 9 directly rather than may attach the separately scaled plate 15, as illustrated in figure 4.
  • the indications of standard chair height 12 engraved on said chair height lookup plate 1 1 is set to the standard height such as the order of 70cm , and the stature scale 13 is indicated by the range of 100 to 1 85cm, so that the chair may be used by all persons from children to adults. Further, the optimum standard height scale I ⁇ is indicated to be viewed with the stature scale as the optimum standard height related to the user's stature when the standard desk height is used as the reference.
  • the optimum standard chair height means the height covering from a pit of stomach to a navel when an user ists on a chair in front of a desk, which results in provi ding the user with the most comfortable posture.
  • the optimum standard height becomes the order of 39.5cm for a person having the stature of 1 70cm while becomes the order of 37.5cm for a person having the stature of 1 80cm.
  • Said stature scale 1 3 of a hookup plate 1 1 and said optimum standard height scale 1 4 indicate the indications or marks as the reduced scale in relation to the size in the lookup plate I I , while the chair height scale 1 6 of a scaled plate 1 5 indicates the marks as the real scale.
  • a guide plate 20 which engraves the guide words as follows : "The stature scale on a lookup plate and the optimum standard height scale of this chair are to use the chair height of 70cm as their reference.” and "In case that the chair height is higher or lower than 70cm, please adjust the chair height by adding or subtracting the difference of chair height to or from the optimum standard chair height on the lookup plate respectively".
  • a user In using the chair in accordance with the present invention, a user first must read the optimum standard chair height with reference to his stature from the stature scale 13 of a chair height lookup plate 1 1 and the optimum standard height scale 14 ; and then release the setscrew 7 and lift the lifting strut 5 against the supporting cylinder 2, in such a manner that matches the scale corresponding to said read height value in the scale 16 of a chair height scale plate 5 with the upper surface of supporting cylinder 2, to adjust the height of seat plate 14 into the optimum height ; and thereafter tighten up the setscrew 7 and fix the lifting strut 5 into the supporting cylinder 2.
  • a child having the statute of 145cm must set the chair height scale 1 6 to 44.5cm, while an adult having that of 1 85cm must set the chair height scale to 36.5cm.
  • An emb'odiment as shown in the drawings is to set the stature scale 1 3 and the optimum standard chair height 1 for the chair height of 70cm, and which may be used by setting the same to the height adding or subtracting the difference of chair height to or from the optimum standard chair height obtained in the lookup plate 1 1 if a chair having the height of more or less than 70cm is used.
  • a person having the stature of 1 70cm must adjust the chair height into 41 .5cm, which is a value adding the optimum standard height of 39.5cm obtained in the lookup plate ! 1 to the difference of 2cm.
