Description
本創作係有關一種座椅扶手，尤指應用棘輪結構之單向步進原理，進而達到快速方便操作之角度調整與定位之一種座椅扶手之改良結構。This creation is related to a seat armrest, especially the one-way stepping principle of the ratchet structure to achieve quick and convenient operation of angle adjustment and positioning.
按，汽車是現代人代步的交通工具，一般汽車座椅之扶手大多固設於座椅旁側，而駕駛者於駕駛時，其手部因長期懸空握持方向盤，將會產生痠痛疲倦之情事，因此設置汽車扶手之目的，就是讓駕駛者甚至乘坐者可將手肘靠置於扶手上，為手肘帶來舒適感。By the way, cars are the means of transportation for modern people. Generally, the armrests of car seats are mostly fixed on the side of the seat. When driving, the hands of the driver will be sore and tired due to holding the steering wheel in the air for a long time. Therefore, the purpose of setting car armrests is to allow drivers and even passengers to place their elbows on the armrests to bring comfort to the elbows.
又按，習知汽車座椅之扶手僅有兩種位置，即垂直豎立或水平定位，由於座椅扶手並不如同椅背具備可調整角度的功能，因此縱使椅背已經調整到讓乘員感覺到最舒適的位置，但因無法調整座椅扶手的角度，致使座椅整體乘坐的舒適性還是打了折扣。Press again, the armrest of the conventional car seat has only two positions, namely vertical erection or horizontal positioning. Since the armrest of the seat does not have the function of adjusting the angle like the seat back, even the seat back has been adjusted to make the occupant feel The most comfortable position, but because the angle of the armrest of the seat cannot be adjusted, the overall comfort of the seat is still compromised.
再按，近期汽車座椅之扶手已發展到可調整角度的功能，但大多數的扶手只限固定且極少段的角度可進行調整及固定，且無意中調整過頭時，該扶手必須被重置到最底端位置再逐段上拉尋找較適意的位置，因此該操作既費時且不易達到滿意的效果。Press again. Recently, the armrest of the car seat has been developed to the function of adjustable angle, but most armrests are only fixed and a small number of angles can be adjusted and fixed, and the armrest must be reset if it is adjusted inadvertently. Go to the bottom end and then pull up section by section to find a more suitable position. Therefore, this operation is time-consuming and not easy to achieve satisfactory results.
本創作人為改善前述座椅扶手調整過頭時，必須被重置到最底端位置再逐段上拉的缺失，曾研發可調整角度之汽車座椅扶手；惟查，該座椅扶手中之定位盤與制動件機構，其相互卡制的棘齒並非屬於『棘輪機構』，因此在調整扶手角度之前，都需按壓一按鈕機構以推動該卡制件，使其與定位盤脫離嚙合，方能使該定位盤進行正向或逆向轉動而轉動扶手；由於雙向調整扶手角度，都需按壓按鈕機構，故知其操作仍未達快速與方便性。In order to improve the aforementioned lack of seat armrests that have to be reset to the bottom end position and then pulled up section by section when the armrest of the seat is adjusted too far, the author has developed an adjustable angle car seat armrest; however, the position in the armrest of the seat The interlocking ratchet teeth of the disc and brake mechanism do not belong to the "ratchet mechanism". Therefore, before adjusting the armrest angle, you need to press a button mechanism to push the clamping element out of engagement with the positioning disc. The positioning plate is rotated in a forward or reverse direction to rotate the armrest; since the two-way adjustment of the armrest angle requires a push button mechanism, it is known that the operation is still not fast and convenient.
緣是，本創作之主要目的，係在應用棘輪機構之單向步進原理，以改善先前技術中扶手調整角度之缺失，並使汽車座椅扶手可方便操作進而達到多段角度之調整功能，以帶給乘坐者手肘之舒適感。The reason is that the main purpose of this creation is to apply the one-way stepping principle of the ratchet mechanism to improve the lack of armrest adjustment angle in the prior art, and to make the car seat armrest easy to operate to achieve the multi-stage angle adjustment function. Brings the comfort of the elbow of the rider.
按，棘輪機構(ratchet mechanism)，係由搖桿、棘輪(ratchet )和棘爪(pawl)所組成，當搖桿順向擺動時，棘爪在棘輪的齒背上滑動，並***其齒槽中構成步進運動；當搖桿要逆向擺動時，棘爪則阻止棘輪轉動，因而構成棘輪機構之單向步進運動。本創作的理念中，就是將樞設在座椅的扶手座體當作搖桿，該座體內側端則穿設一做為迴轉中心的中心軸，將棘輪盤固設在中心軸外緣，再將棘爪樞設在座體內，並使其棘齒與棘輪盤的棘齒相卡合；當扶手座體的外側端朝向上方樞轉時，就相當是棘輪機構的搖桿順向擺動，此時棘爪在棘輪盤的齒背上滑動，並***其齒槽中構成步進運動，且扶手座體可在順向擺動中的任意位置停止其運動，且扶手座體若要逆向擺動，則棘爪隨即阻止棘輪盤的轉動，因此本創作的扶手機構可達到多段角度之調整功能。 Press, ratchet mechanism (ratchet mechanism), tied by rocker, ratchet (ratchet ) And pawl. When the rocker swings in the forward direction, the pawl slides on the tooth back of the ratchet wheel and is inserted into the tooth groove to form a stepping motion; when the rocker swings in the opposite direction, the pawl The ratchet wheel is prevented from rotating, thus forming the one-way stepping movement of the ratchet mechanism. In the concept of this creation, the armrest seat body pivoted on the seat is used as a rocker, and the inner end of the seat body is penetrated with a central shaft as the center of rotation, and the ratchet disc is fixed on the outer edge of the central shaft. Then pivot the pawl in the seat and make the ratchet teeth engage with the ratchet teeth of the ratchet disk; when the outer end of the armrest seat pivots upward, it is equivalent to the rocker of the ratchet mechanism swinging in the forward direction. When the pawl slides on the tooth back of the ratchet disc and inserts it into the tooth groove to form a stepping motion, and the armrest seat body can stop its movement at any position in the forward swing, and if the armrest seat body is to swing in the reverse direction, The pawl immediately prevents the rotation of the ratchet wheel, so the armrest mechanism of this creation can achieve multi-stage angle adjustment.

藉助前揭特徵，本創作「座椅扶手之改良結構」具有如下之效益： (1)本創作係在棘輪盤之外緣設有複數個棘齒，且係固設在與座椅連結之中心軸上，而棘爪則設置於可相對該中心軸進行樞轉之底座上；參照棘輪機構單向步進運動的原理，當乘坐者順向樞轉扶手座體時，棘爪的棘齒將持續在棘輪盤的齒背上滑動，直到扶手座體的最上點位置之前的任意位置停止其運動，棘爪的棘齒隨即***棘輪盤的齒槽中以阻止其逆向轉動；由於順向操作時無需按壓其按鈕以使棘輪盤脫離棘爪的卡制，因此本創作只需輕鬆地樞轉扶手，即可輕巧而方便地達到快速調整座椅扶手之效果。 (2)本創作係應用棘輪機構的原理設置相互嚙合的棘輪盤與棘爪機構， 由於棘輪盤逆向轉動時將受到棘爪的卡制，故需按壓其按鈕使棘輪盤脫離棘爪，扶手座體方能逆向樞轉至其最下點位置之前的任意位置，因此本創作只要按壓其按鈕即可逆向樞轉，使座椅扶手調整至其所欲之角度，以滿足乘坐者手肘之舒適感。 (3)本創作中其棘爪設有複數棘齒，並使其與該棘輪盤維持二齒以上之嚙合，由於棘齒相互接觸的表面積增加，且當乘坐者手肘放置於扶手座體上時，棘爪對該棘輪盤的卡制力將亦加增強，甚至該卡制力將遠大於按鈕的按壓力，此時必須將手肘移開且微微上拉扶手座體以減少棘齒的接觸面積，才有按壓其按鈕的效果，因此設有複數棘齒的棘爪將使本創作提升機構的可靠性與安全性。 (4)本創作中該定位擋板係固設在與座椅連結之中心軸上，而限位銷則固設於可相對該中心軸進行樞轉之底座上，因此乘坐者在樞轉底座時，該定位擋板之限位塊將被該限位銷所止擋；由於本創作係應用限位銷與定位擋板之止擋作用，以限制座椅扶手樞轉之最上點與最下點位置，故而本創作可確保底座樞轉角度的安全範圍。 (5)本創作「座椅扶手之改良結構」主要係為汽車座椅而開創者，惟應用上並不限於汽車領域，包括交通運輸工具，以及辦公室或居家，舉凡座椅兩側裝設有扶手者，均可適用本創作。 With the help of the front reveal feature, this creation "Improved Structure of Seat Armrest" has the following benefits: (1) This creation is provided with a plurality of ratchet teeth on the outer edge of the ratchet wheel, and they are fixed on the central axis connected with the seat, and the pawls are arranged on the base that can pivot relative to the central axis ; With reference to the principle of the one-way stepping movement of the ratchet mechanism, when the occupant pivots the armrest seat in the forward direction, the ratchet teeth of the pawl will continue to slide on the tooth back of the ratchet wheel until the position before the uppermost point of the armrest seat Stop its movement at any position, and the ratchet teeth of the pawl will be inserted into the tooth groove of the ratchet disc to prevent it from rotating in the reverse direction; since there is no need to press its button to release the ratchet disc from the pawl during the forward operation, the creation only needs to By easily pivoting the armrest, you can quickly adjust the armrest of the seat lightly and conveniently. (2) This creation system uses the principle of the ratchet mechanism to set up mutually meshing ratchet disc and pawl mechanism. Since the ratchet disc will be blocked by the pawl when it rotates in the reverse direction, it is necessary to press its button to disengage the ratchet disc from the pawl, so that the armrest seat body can reversely pivot to any position before its lowest point, so this creation only needs to press The button can be reversely pivoted to adjust the armrest of the seat to the desired angle to meet the comfort of the occupant's elbow. (3) In this creation, the pawl is provided with a plurality of ratchet teeth, and the ratchet wheel is maintained to mesh with more than two teeth. As the surface area of the ratchet teeth contact with each other increases, and when the occupant's elbow is placed on the armrest seat body At this time, the locking force of the pawl on the ratchet disk will also increase, and even the locking force will be much greater than the pressing force of the button. At this time, the elbow must be removed and the armrest seat body must be slightly pulled up to reduce the ratchet The contact area has the effect of pressing the button, so the pawl with multiple ratchet teeth will enhance the reliability and safety of the mechanism. (4) In this creation, the positioning baffle is fixed on the central axis connected with the seat, and the limit pin is fixed on the base that can pivot relative to the central axis, so the occupant is on the pivoting base When, the limit block of the positioning baffle will be stopped by the limit pin; because this creation uses the stop function of the limit pin and the positioning baffle to limit the uppermost point and the bottom of the seat armrest pivot Point position, so this creation can ensure the safety range of the pivot angle of the base. (5) This creation "Improved structure of seat armrests" is mainly pioneered for car seats, but the application is not limited to the automotive field, including transportation, as well as offices or homes, where the seats are equipped with Those with armrests can apply this creation.

本創作為使汽車座椅扶手在滿足舒適感覺的位置中進行角度調整，有進一步設定該扶手座體10其樞轉之最上點Pt與最下點Pb之位置，如圖4所示；其做法係在該底座11外緣之中心軸21上組設一定位擋板28，且該定位擋板28之外緣設有二對稱之限位塊281，同時該底座11外緣臨近該樞軸孔112處則設有與該二限位塊281相對應之二限位銷29；乘坐者若要調整座椅扶手至最上點位置Pt時，可轉動該扶手座體10之外側端使其以該中心軸21為軸心持續向上方樞轉，則該二限位銷29將同時擋止該定位擋板28之二限位塊281，使該扶手座體10無法繼續轉動，此時，該扶手座體10之外側端處於最上點位置Pt，且該棘爪31之棘齒312將卡制該棘輪盤23之止擋塊232，如圖5所示；乘坐者若要調整汽車座椅扶手至最下點位置Pb，則按壓該按鈕41使棘爪31之棘齒312脫離與該棘輪盤23之嚙合後，轉動該扶手座體10之外側端使其以該中心軸21為軸心持續向下方樞轉，則該二限位銷29將擋止該定位擋板28之二限位塊281，使該扶手座體10無法繼續轉動，放開該按鈕41則該棘爪31之棘齒312將卡制該棘輪盤23最下端之棘齒231，如圖6所示。This creation is to adjust the angle of the armrest of the car seat in a position that satisfies the comfortable feeling. It further sets the position of the uppermost point Pt and the lowermost point Pb of the
本創作係在棘輪盤23之外緣設有複數個棘齒231，且係固設在與座椅連結之中心軸21上，而棘爪31則設置於可相對該中心軸21進行樞轉之底座11上；參照棘輪機構單向步進運動的原理，當乘坐者順向樞轉扶手座體10時，棘爪31的棘齒312將持續在棘輪盤23的齒背上滑動，直到扶手座體10的最上點Pt位置之前的任意位置停止其運動，棘爪31的棘齒312隨即***棘輪盤23的齒槽中以阻止其逆向轉動；由於順向操作時無需按壓其按鈕41以使棘輪盤23脫離棘爪31的卡制，因此本創作只需輕鬆地樞轉扶手座體10，即可輕巧而方便地達到快速調整座椅扶手之效果。次者，本創作係應用棘輪機構的原理設置相互嚙合的棘輪盤23與棘爪31機構，由於棘輪盤23逆向轉動時將受到棘爪31的卡制，故需按壓其按鈕41使棘輪盤23脫離棘爪31，扶手座體10方能逆向樞轉至其最下點Pb位置之前的任意位置，因此本創作只要按壓其按鈕41即可逆向樞轉，使座椅扶手調整至其所欲之角度
，以滿足乘坐者手肘之舒適感。又者，本創作中其棘爪31設有複數棘齒312，並使其與該棘輪盤23維持二齒以上之嚙合，由於棘齒231/312相互接觸的表面積增加，且當乘坐者手肘放置於扶手座體10上時，棘爪31對該棘輪盤23的卡制力將亦加增強，甚至該卡制力將遠大於按鈕41的按壓力，此時必須將手肘移開且微微上拉扶手座體10以減少棘齒231/312的接觸面積，才有按壓其按鈕的效果，因此設有複數棘齒312的棘爪31將使本創作提升機構的可靠性與安全性。又者，本創作中該定位擋板28係固設在與座椅連結之中心軸21上，而限位銷29則固設於可相對該中心軸21進行樞轉之底座11上，因此乘坐者在樞轉扶手座體10時，該定位擋板28之限位塊281將被該限位銷29所止擋
；由於本創作係應用限位銷29與定位擋板28之止擋作用，以限制座椅扶手樞轉之最上點Pt與最下點Pb位置，故而本創作可確保扶手座體10樞轉角度的安全範圍。再者，本創作「座椅扶手之改良結構」主要係為汽車座椅而開創者，惟應用上並不限於汽車領域，包括交通運輸工具，以及辦公室或居家，舉凡座椅兩側裝設有扶手者，均可適用本創作。
