Description
本考案は、背もたれに設けられた、背もたれのフレームに沿って上下にスライド移動可能、かつ着座者の腰部を支持する腰支持部と、背もたれのフレームには更に、ウォームに噛み合わせ、第二歯車と並ぶ第一歯車と、ウォームを貫通してユーザに回転される調整レバーと、腰支持部には第二歯車に噛み合わせるギアラックとが設けられ、調整レバーを回して、ウォームと第一歯車、第二歯車を回転させて、ギアラックを動かすことにより、腰支持部を上下に調整するように設けられる装置に関する。 According to the present invention, a waist support portion provided on the backrest that can slide up and down along the frame of the backrest and supports the waist of the seated person, and the frame of the backrest are further meshed with a worm to provide a second gear. A first gear lined up with the worm, an adjustment lever that is rotated by the user through the worm, and a gear rack that meshes with the second gear are provided on the waist support, and the adjustment lever is turned to turn the worm and the first gear. The present invention relates to a device provided so as to adjust a waist support portion up and down by rotating a second gear and moving a gear rack.
一般的なオフィスチェアでは、着座者の背中を預けるための背もたれは、着座者が背筋をまっすぐ伸ばすのに必要な力を減らし、長時間かつ心地よく座れるように設けられるのが目的である。背もたれには、着座者の背中を預ける背支持部のほかに、背支持部の下方に、着座者の腰部を支持するための腰支持部が増設し、座り心地のよさを高めるように設けられる。 In a typical office chair, the backrest for the back of the seated person is intended to reduce the force required for the seated person to straighten the back muscle and to be provided so that the seated person can sit comfortably for a long time. In addition to the back support part that holds the back of the seated person, the backrest is provided with a waist support part below the back support part to support the waist part of the seated person so as to enhance the sitting comfort. ..
背もたれに設けられる腰支持部は通常、固定されており、決まった高さに固定され、調整できないものであるため、着座者の身長差による腰部の高さにより、前記腰支持部からの支持を完全は得られない恐れがあり、腰支持部の本来の効果を発揮できない場合がある。 Since the waist support provided on the backrest is usually fixed, fixed at a fixed height, and cannot be adjusted, the height of the waist due to the height difference of the seated person provides support from the waist support. It may not be perfect, and the original effect of the lumbar support may not be exhibited.
従来の特許文献では、登録特許ＣＮ２６１２２８８Ｙに掲示されたように、高さが上下調整可能な腰支持部が設けられ、腰支持部本体の両側には埋込フックが設けられ、それに対応するところの背もたれのフレームの両側には、埋込フックを嵌め込むための調整可能なロング溝が設けられ、即ち、埋込フックを、調整可能なロング溝を上下スライド移動させるためように設けられ、腰支持部本体は更に、強い締め付けの背もたれのメッシュ体に受けられ、力を入れず、腰支持部を調整しないとき、前記腰支持部が移動しないのに対し、上下に力を入れて腰支持部を動かすと、腰支持部が着座者の腰部に適した位置にスライド移動するように設けられる。 In the conventional patent document, as posted in the registered patent CN261288Y, a waist support portion whose height can be adjusted up and down is provided, and embedded hooks are provided on both sides of the waist support portion main body, corresponding to the waist support portion. Adjustable long grooves for fitting the embedded hooks are provided on both sides of the backrest frame, i.e., the embedded hooks are provided to slide the adjustable long grooves up and down to support the waist. The body of the part is further received by the mesh body of the backrest that is strongly tightened, and when the waist support is not adjusted without applying force, the waist support does not move, whereas the waist support is applied with force up and down. When moved, the waist support is provided so as to slide to a position suitable for the seated person's waist.
しかし、上述したような上下調整可能な腰支持部は、上下調整の時、着座者が両側から力を均等に入れる必要があり、傾斜などになりがちで、調整が難しくなるからであること。その調整は通常、着座者が椅子に座り、背もたれについてから、両手を後ろへ、腰支持部の両側まで伸ばし、力を入れて、腰支持部を、腰部を支持するのに適したところまで上下調整するが、両手を後ろへ伸ばして、力を入れて上下調整するには、両側に力を均等に入れるのが難しく、そこで、腰支持部が傾斜したりして、調整しにくくなるという問題がある。 However, the waist support portion that can be adjusted up and down as described above requires the seater to apply force evenly from both sides at the time of up and down adjustment, and tends to be tilted, which makes adjustment difficult. The adjustment is usually made by the seated person sitting in a chair, from the backrest, with both hands behind, extending to both sides of the lumbar support and exerting force to raise and lower the lumbar support to a position suitable for supporting the lumbar region. Although it is adjusted, it is difficult to apply force evenly to both sides in order to extend both hands backward and apply force to adjust up and down, so there is a problem that the waist support is tilted and it is difficult to adjust. There is.
腰支持部は、背もたれのメッシュ体の強い締付け力によって、位置決められ、移動しないように設けられるが、メッシュ体が長時間使用され、緩んだりすると、腰支持部を止める力が大幅に低下し、安定した位置決めができず、ないし位置決めができなくなり、下へ滑り落ちてしまうという問題がある。 The waist support is positioned so that it does not move due to the strong tightening force of the mesh body of the backrest, but if the mesh body is used for a long time and loosens, the force to stop the waist support is greatly reduced. There is a problem that stable positioning cannot be performed, or positioning cannot be performed, and the body slides down.
それゆえ、本考案は、上述した従来の知られている腰支持部の調整の難しさ、及び背もたれのメッシュ体の緩みによる滑り落ちという問題を解決するため、背もたれのフレームに、調整レバーの回転によって動かされるウォームと歯車とが設けられ、歯車を背もたれのフレームに設けられた、腰支持部の後ろにあるスライド移動可能なギアラックに噛み合わせるように設けられ、着座者が片手又は両手で、調整レバーを回すと、簡易に腰支持部を上下調整することができ、適した高さまで調整した後、腰支持部がスライド移動しないように設けられる装置を提供することを目的とする。 Therefore, in order to solve the above-mentioned difficulty of adjusting the waist support and the problem of slipping off due to loosening of the mesh body of the backrest, the present invention has the rotation of the adjusting lever on the frame of the backrest. A worm and gears that are driven by the worms and gears are provided so that the gears mesh with a slideable gear rack behind the waist support provided on the frame of the backrest, allowing the seated person to adjust with one or both hands. It is an object of the present invention to provide a device in which the waist support portion can be easily adjusted up and down by turning a lever, and after adjusting to a suitable height, the waist support portion is provided so as not to slide and move.
本実用新案の課題を解決しようとする技術として、背もたれのフレームの上方には背支持部、背支持部の下方にある背もたれのフレームにはスライド移動可能な腰支持部、前記腰支持部の後ろには縦向きのギアラック、前記ギアラックに対応したところの背もたれのフレームにはギアラックに噛み合わせるための第二歯車、 第二歯車には更に同軸かつ同時回転する第一歯車が設けられ、 背もたれのフレームには収納スロットが設けられ、前記収納スロット内には、前記第一歯車、第二歯車を固定するための支軸が設けられ、背もたれのフレームには更に、横から収納スロットを貫通する調整レバーが設けられ、調整レバーで、前記収納スロット内にある前記第一歯車に噛み合わせるウォームを貫通固定し、更に、調整レバーを回して、第一歯車、第二歯車とギアラックによって、腰支持部の位置を上下に調整するように設けられることを特徴とする背もたれの腰支持部の高さ調整可能な装置。 As a technique for solving the problems of the present practical novel, the back support portion is above the backrest frame, the backrest frame below the backrest support portion has a slideable waist support portion, and the back of the waist support portion. Is provided with a vertical gear rack, the backrest frame corresponding to the gear rack is provided with a second gear for meshing with the gear rack, and the second gear is further provided with a first gear that is coaxial and simultaneously rotating. Is provided with a storage slot, a support shaft for fixing the first gear and the second gear is provided in the storage slot, and an adjustment lever that penetrates the storage slot from the side is further provided on the backrest frame.
