背景技术Background technique

以往,监视器、电脑、电视机等各种装置是通过各种形式的装置支承臂设置在办公室或家庭等中、或者汽车等车辆、飞机、船舶等中而使用的。一般情况下,装置支承臂的多个臂通过铰链装置可相互转动地连接,并且,各个臂被连接成可保持任意的转动角度,在安装端部固定基端侧臂,在前端侧臂上安装各种装置,以便各种装置可在各个臂的长度范围内自由移动地设置在安装端部上。例如,日本专利JP-9-326980-A披露了这种装置支承臂。在该文献的支承臂中,通过具有转动阻力的关节部(铰链装置)可自由转动地连接多个臂,在该支承臂的前端枢轴支承信息监视器,以便能够朝向所希望的方向保持信息监视器。Conventionally, various devices such as monitors, computers, and televisions have been installed in offices, homes, etc., or in vehicles such as automobiles, airplanes, ships, etc., with various types of device support arms. In general, a plurality of arms of the device supporting arm are rotatably connected to each other by a hinge device, and each arm is connected so as to maintain any rotation angle, and the base end side arm is fixed at the installation end, and the front end side arm is installed. Various means are provided on the mounting end so that the various means are freely movable within the length of each arm. For example, Japanese Patent JP-9-326980-A discloses such a device support arm. In the supporting arm of this document, a plurality of arms are freely rotatably connected by a joint portion (hinge device) having rotational resistance, and an information monitor is pivotally supported at the front end of the supporting arm so that the information can be held in a desired direction. monitor.

但是,在上述以往的装置支承臂中,多个臂之间的各个关节部件通过仅仅利用蝶形弹簧或垫圈等在各个臂之间提供摩擦阻力作用的铰链机构构成,由于仅仅通过所述蝶形弹簧或垫圈等的摩擦阻力作用承受监视器等各种装置的载荷和各种臂的载荷,因此,对于这种关节部件所具有的保持各个臂之间角度的能力而言,载荷过大。所以,这种支承臂存在的问题在于:从使用开始不久,支承监视器等各种装置的能力便逐渐降低,装置逐渐下落,从而不能长期稳定地保持在使用者所要求的规定位置处。另外,这种装置支承臂例如在车辆等中使用时,由于易于受到振动的影响,因此,存在支承的装置易于下落,难以长期稳定地保持在最适于使用者使用的位置处的问题。However, in the above-mentioned conventional device support arms, each joint member between a plurality of arms is constituted by a hinge mechanism that provides frictional resistance between the arms only by using butterfly springs or washers, since only the butterfly The frictional resistance action of springs or washers bears the load of various devices such as monitors and the loads of various arms, so the load is too large for the ability of such joint parts to maintain the angle between the arms. Therefore, there is a problem with this supporting arm that the ability to support various devices such as a monitor gradually decreases shortly after use, and the device gradually falls, so that it cannot be stably held at a predetermined position required by the user for a long time. In addition, when such a device support arm is used in a vehicle, for example, it is easily affected by vibrations, so the supported device tends to fall, and it is difficult to maintain the most suitable position for the user stably for a long time.

在安装手柄833之前,在将螺旋弹簧84卷绕安装在各个销831周围并卡定在凸缘832上的状态下,将该锁定销83由各个销831的基端部,从各个销导引件850的大径销贯通部851穿过并贯通安装在销壳体85中。之后,将手柄833安装在贯通各个销导引件850的各个销831的基端部上,组装锁定销83和销壳体85。通过这种组装,锁定销83的各个销831由设置在各个销导引件850内的各个螺旋弹簧84施力,从而形成前端侧从各个销导引件850的前端伸出的状态。这样,对于装配在销壳体85中的锁定销83而言,使各个销831贯通安装托架16的各个导引孔82,将销壳体85设置在安装托架16的一个轴承部164中并通过穿过固定部854的螺钉贯通部的螺钉固定在一个轴承部164上。这样,锁定销83朝锁定槽81可进退地设置在安装托架16的一个轴承部164的导引孔82上,并且,通过螺旋弹簧84的施力,在常态下向锁定槽81滑动卡合,并通过手柄833的操作,使其沿牵引方向滑动,由此使锁定销83与各个锁定槽81脱离。Before attaching thehandle 833, in a state where thecoil spring 84 is wound around eachpin 831 and locked on theflange 832, thelock pin 83 is guided from each pin by the base end of eachpin 831. The large-diameterpin penetration portion 851 of themember 850 passes through and is installed in thepin housing 85 . Thereafter, thehandle 833 is mounted on the base end portion of eachpin 831 penetrating eachpin guide 850 , and thelock pin 83 and thepin housing 85 are assembled. With this assembly, eachpin 831 of thelock pin 83 is biased by eachcoil spring 84 provided in eachpin guide 850 , thereby forming a state where the front end side protrudes from the front end of eachpin guide 850 . In this way, for thelock pin 83 assembled in thepin housing 85, eachpin 831 is made to pass through eachguide hole 82 of the mountingbracket 16, and thepin housing 85 is set in onebearing portion 164 of the mountingbracket 16. And it is fixed on abearing part 164 by the screw passing through the screw penetration part of the fixingpart 854 . In this way, the lockingpin 83 is set on theguide hole 82 of a bearingportion 164 of the mountingbracket 16 so as to move forward and backward toward the lockinggroove 81, and is slidably engaged with the lockinggroove 81 under normal conditions by the biasing force of thecoil spring 84. , and through the operation of thehandle 833 , it slides along the pulling direction, thereby disengaging the lockingpin 83 from each lockinggroove 81 .

另外,在本实施方式中,为了以任意的转动角度,将基座板15可靠地固定保持在安装托架16的前表面161上,在基座板15的背面侧附设有螺旋式的止动件9。In addition, in this embodiment, in order to securely fix and hold thebase plate 15 on thefront surface 161 of the mountingbracket 16 at any rotation angle, a screw-type stopper is attached to the back side of thebase plate 15 .Item 9.

Each stoppermain body 91 consists of a threadedshaft 911 that can be screwed into the threadedhole 90 to the back of thebase plate 15, is fixed on the front end of the threadedshaft 911, and is in surface contact with the back of thebase plate 15. Thecontact member 912 made of a material with a relatively high coefficient of friction and theknob 913 integrally mounted on the rear end of the threadedshaft 911 is rotatable. A pair of stoppermain bodies 91 , 91 are inserted above and below thefront surface 161 of the mountingbracket 16 so that the back surface of thebase plate 15 can be pressed. For each stoppermain body 91, by turning theknob 913 in the direction of feeding the threadedshaft 911 to the back of thebase plate 15, thecontact member 912 pushes into contact with the back of thebase plate 15 to limit the direction of its rotation. Movement, on the other hand, by turning theknob 913 in the opposite direction, thecontact member 912 moves away from the back of thebase plate 15, allowing it to turn.

具有这种结构的监视器臂1通过固定底座14,将基端侧臂11固定在车辆驾驶室内的仪表板等安装端上,并将监视器安装在装配于前端侧臂13上的基座板15上,从而能够在车辆驾驶室内,以在臂11、12、13的长度范围内可移动(调节)的方式设置监视器。The monitor arm 1 having such a structure fixes the baseend side arm 11 to an installation end such as an instrument panel in the vehicle cab by fixing thebase 14, and mounts the monitor on the base plate mounted on the frontend side arm 13. 15, so that the monitor can be installed in a movable (adjustable) manner within the length range of thearms 11, 12, 13 in the vehicle cab.

另外,该监视器臂1通过将杆6、6朝上下方向(垂直方向)固定在安装端上,使得中间臂12可以相对于基端侧臂11以轴212为中心朝左右方向(水平方向)转动,前端侧臂13可以相对于中间臂12以轴222为中心朝左右方向(水平方向)转动,基座板15的安装托架16可以相对于前端侧臂13以销171为中心朝上下方向(垂直方向)转动,并且,基座板15可以在安装托架16的前表面161以螺栓153为中心转动。另外,对于该监视器臂1而言,若朝左右方向(水平方向)将杆6、6固定在安装端上,则中间臂12可以相对于基端侧臂11以轴212为中心朝上下方向(垂直方向)转动,前端侧臂13可以相对于中间臂12以轴222为中心朝上下方向(垂直方向)转动,基座板15的安装托架16可以相对于前端侧臂13以销171为中心朝左右方向(水平方向)转动,并且,基座板15可以在安装托架16的前表面161上以螺栓153为中心转动。In addition, the monitor arm 1 is fixed on the mounting end by fixing therods 6, 6 in the vertical direction (vertical direction), so that themiddle arm 12 can move in the left and right direction (horizontal direction) with respect to the baseend side arm 11 centered on theaxis 212. Rotate, the frontend side arm 13 can rotate in the left and right direction (horizontal direction) with respect to themiddle arm 12 centering on theshaft 222, and the mountingbracket 16 of thebase plate 15 can face in the up and down direction with respect to the frontend side arm 13 centering on the pin 171 (vertical direction), and thebase plate 15 can be rotated around thebolt 153 on thefront surface 161 of the mountingbracket 16 . In addition, in this monitor arm 1, if therods 6 and 6 are fixed to the mounting end in the left-right direction (horizontal direction), theintermediate arm 12 can be directed upward and downward with respect to the base-end side arm 11 around theaxis 212. (vertical direction) rotation, the frontend side arm 13 can rotate toward the up and down direction (vertical direction) with respect to themiddle arm 12 centering on theshaft 222, and the mountingbracket 16 of thebase plate 15 can be relative to the frontend side arm 13 with thepin 171 as the center. The center is turned in the left-right direction (horizontal direction), and thebase plate 15 can be turned on thefront surface 161 of the mountingbracket 16 centering on thebolt 153 .

在通过该监视器臂1调节监视器的位置的情况下,使固定侧以及可动侧的定位导引件3、4形成非卡合状态,使各个臂11、12、13相互朝左右方向(水平方向)或上下方向(垂直方向)转动,以调节成任意的转动角度。When the position of the monitor is adjusted by the monitor arm 1, the positioning guides 3, 4 on the fixed side and the movable side are disengaged, and thearms 11, 12, 13 face each other in the left-right direction ( Horizontal direction) or up and down direction (vertical direction) to adjust to any rotation angle.

在图8中显示了相对于基端侧臂11使中间臂12朝左右方向(或上下方向)转动,以调节臂1整体的左右方向(或上下方向)的角度的状态。中间臂12通过轴212,沿左右方向(或上下方向)可转动地与基端侧臂11结合。在中间臂12的可动侧定位导引件4离开基端侧臂11的固定侧定位导引件3的状态下,若使中间臂12相对于基端侧臂11向右方向或向左方向(或上下方向)转动,则在该中间臂12运动的同时,可动侧定位导引件4在不接触的情况下,绕固定侧定位导引件3的多个槽301移动。若使中间臂12的转动停止,则在该位置处,可动侧定位导引件4的爪401与固定侧定位导引件3的一部分的槽301相对。这样,能使中间臂12相对于基端侧臂11以任意方向转动,并能设定任意的转动角度。FIG. 8 shows a state in which the angle of the entire arm 1 in the left-right direction (or vertical direction) is adjusted by rotating theintermediate arm 12 in the left-right direction (or vertical direction) relative to the base-end side arm 11 . Theintermediate arm 12 is rotatably coupled to theproximal side arm 11 in the left-right direction (or up-down direction) via ashaft 212 . In the state where the movable-side positioning guide 4 of theintermediate arm 12 is separated from the fixed-side positioning guide 3 of the base-end arm 11, if theintermediate arm 12 is moved to the right or to the left relative to the base-end arm 11 (or up and down) rotation, while theintermediate arm 12 moves, the movableside positioning guide 4 moves around the plurality ofgrooves 301 of the fixedside positioning guide 3 without contact. When the rotation of theintermediate arm 12 is stopped, thepawl 401 of the movable-side positioning guide 4 faces a part of thegroove 301 of the fixed-side positioning guide 3 at this position. In this way, theintermediate arm 12 can be rotated in any direction relative to theproximal arm 11, and an arbitrary rotation angle can be set.

在图9中显示了使前端侧臂13相对于中间臂12朝左右方向(或上下方向)转动,以调节基座板15的左右方向(或上下方向)的角度的状态。前端侧臂13通过轴222,朝左右方向(或上下方向)可转动地与中间臂12结合。在中间臂12的可动侧定位导引件4离开前端侧臂13的固定侧定位导引件3的状态下,若使前端侧臂13相对于中间臂12向右方向或向左方向(或上下方向)转动,则在该前端侧臂13运动的同时,固定侧定位导引件3在不接触的情况下,绕可动侧定位导引件4的爪401移动。若使前端侧臂13的转动停止,则在该位置处,可动侧定位导引件4的爪401与固定侧定位导引件3的一部分的槽301相对。这样,能使前端侧臂13相对于中间臂12以任意方向转动,并能设定任意的转动角度。FIG. 9 shows a state in which the angle of thebase plate 15 is adjusted in the left-right direction (or vertical direction) by rotating the front-end side arm 13 in the left-right direction (or vertical direction) relative to theintermediate arm 12 . The frontend side arm 13 is rotatably coupled to themiddle arm 12 in the left and right direction (or in the up and down direction) via theshaft 222 . In the state where the movable-side positioning guide 4 of theintermediate arm 12 is separated from the fixed-side positioning guide 3 of the front-end side arm 13, if the front-end side arm 13 is moved to the right or to the left relative to the middle arm 12 (or (up and down direction), while the frontend side arm 13 moves, the fixedside positioning guide 3 moves around thepawl 401 of the movableside positioning guide 4 without contact. When the rotation of the frontend side arm 13 is stopped, thepawl 401 of the movableside positioning guide 4 faces the part of thegroove 301 of the fixedside positioning guide 3 at this position. In this way, the frontend side arm 13 can be rotated in any direction relative to theintermediate arm 12, and an arbitrary rotation angle can be set.

通过这种各个臂11、12、13之间的角度调节,可以使臂11、12、13整体从固定底座14向正面以直线状延伸,朝斜右方或斜左方(或上下方向)以直线状延伸,或者垂直地向右方或向左方(或者上下方向)直线状延伸。另外,还可以使各个臂11、12、13从固定底座14向正面、以锯齿形或Z形状弯曲,或者朝斜右方或斜左方(或上下方向)以锯齿形或Z形状弯曲,或者垂直地向右方或向左方(或者上下方向)以锯齿形或Z形状弯曲,或者,也可以使各个臂11、12、13折叠到固定底座14上。By adjusting the angle between eacharm 11, 12, 13, thewhole arm 11, 12, 13 can be made to extend in a straight line from the fixedbase 14 to the front, towards the oblique right or oblique left (or up and down) Extend linearly, or extend linearly vertically to the right or left (or up and down). In addition, eacharm 11, 12, 13 may be bent from the fixedbase 14 toward the front in a zigzag or Z shape, or obliquely right or left (or up and down) in a zigzag or Z shape, or Thearm 11 , 12 , 13 may be bent vertically to the right or left (or up and down) in a zigzag or Z shape, or eacharm 11 , 12 , 13 may be folded onto the fixedbase 14 .

这样,若确定了基座板15的位置(即,监视器的位置),则如图8以及图9所示,通过朝规定的方向转动操纵前方以及后方的杆6、6,在通过推压部件51、51向固定侧定位导引件3、3推压可动侧定位导引件4、4的同时,使推压部件51、51与锁定部52、52卡合,从而将臂11、12、13之间锁定在任意的转动角度。In this way, if the position of the base plate 15 (that is, the position of the monitor) is determined, as shown in FIGS. When theparts 51, 51 push the movable side positioning guides 4, 4 toward the fixed side positioning guides 3, 3, the pushingparts 51, 51 are engaged with the lockingparts 52, 52, thereby locking thearms 11, 51 12,13 are locked at any rotation angle.

如图5所示,若向后方推动中间臂12的后方杆6以使其倾斜运动,则安装在杆6下部的推压部件51向后方转动,并向后推压后方可动侧定位导引件4R的被推压部453,从而向固定侧定位导引件3推压移动可动侧定位导引件4R整体,可动侧定位导引件4R的爪401与固定侧定位导引件3的一部分的槽301牢固卡合。之后,若进一步强推该杆6达到极限,则推压部件51越过被推压部453与锁定槽454之间的凸部而与锁定槽454嵌合,并通过该锁定槽454的约束而被固定。藉此,相对于基端侧臂11,以任意的转动角度锁定中间臂12。另外,由于在该实施方式中,在基端侧臂11的轴承21的外周面上,以10°角度间隔形成有多个槽301,因此,中间臂12可以相对于基端侧臂11以10°角度间隔进行角度调节,As shown in Fig. 5, if therear rod 6 of theintermediate arm 12 is pushed backward to make it tilted, the pushingmember 51 installed at the lower part of therod 6 rotates rearward and pushes the rear movable side positioning guide backward. The pushedpart 453 of thepiece 4R, thereby pushing and moving the whole movableside positioning guide 4R toward the fixedside positioning guide 3, theclaw 401 of the movableside positioning guide 4R and the fixed side positioning guide 3 A part of thegroove 301 snaps firmly. Afterwards, if therod 6 is further pushed to the limit, the pushingmember 51 will go over the convex portion between the pushedportion 453 and the lockinggroove 454 to fit into the lockinggroove 454, and be locked by the lockinggroove 454. fixed. Thereby, theintermediate arm 12 is locked at an arbitrary rotation angle with respect to the baseend side arm 11 . In addition, since in this embodiment, on the outer peripheral surface of the bearing 21 of theproximal side arm 11, a plurality ofgrooves 301 are formed at 10° angular intervals, therefore, theintermediate arm 12 can be formed at 10 degrees with respect to theproximal side arm 11. ° angle interval for angle adjustment,

同样,若向前方推动中间臂12的前方杆6并使其倾斜运动,则安装在杆6上部的推压部件51向前方转动,向前方推压前方可动侧定位导引件4F的被推压部453,从而向固定侧定位导引件3推压移动可动侧定位导引件4F整体,使得可动侧定位导引件4的爪401与固定侧定位导引件3的一部分的槽301牢固卡合。之后,若进一步强推该杆6达到极限,则推压部件51越过被推压部453与锁定槽454之间的凸部与锁定槽454嵌合,并通过该锁定槽454的约束而被固定。藉此,相对于中间臂12,能够以任意的转动角度锁定前端侧臂13。另外,由于在该实施方式中,在前端侧臂13的轴承23的外周面上,以10°角度间隔形成有多个槽301,因此,前端侧臂13可以相对于中间臂12以10°角度间隔进行角度调节。Similarly, if thefront rod 6 of theintermediate arm 12 is pushed forward and made to move obliquely, the pushingmember 51 mounted on the top of therod 6 rotates forward, and pushes forward the pushed part of the front movableside positioning guide 4F. Thepressing portion 453 pushes and moves the entire movableside positioning guide 4F toward the fixedside positioning guide 3 so that thepawl 401 of the movableside positioning guide 4 and the groove of a part of the fixedside positioning guide 3 301 snaps firmly together. Afterwards, if therod 6 is pushed further to the limit, the pushingmember 51 will go over the protrusion between the pushedpart 453 and the lockinggroove 454 and fit into the lockinggroove 454, and be fixed by the constraint of the lockinggroove 454. . Thereby, the frontend side arm 13 can be locked at an arbitrary rotation angle with respect to theintermediate arm 12 . In addition, since in this embodiment, on the outer peripheral surface of the bearing 23 of the frontend side arm 13, a plurality ofgrooves 301 are formed at 10° angular intervals, therefore, the frontend side arm 13 can be positioned at an angle of 10° relative to themiddle arm 12. Angle adjustment at intervals.

另外,该监视器臂1在将基座板15的安装托架16朝上下方向可转动地安装在前端侧臂13上的情况下,如图4所示,由于利用通过垫圈168、平垫圈169、碟形弹簧垫圈170在轴承部164、164与轴承部131、131之间产生的摩擦阻力作用与通过扭力螺旋弹簧166推动轴承部164、164相对于轴承部131、131向上方转动的力的合力,能够将安装托架16与前端侧臂13之间保持在上下方向任意的角度,因此,基座板15的(正面的)方向可以调节到上下方向任意的角度,并被保持在任意角度。In addition, in this monitor arm 1, when the mountingbracket 16 of thebase plate 15 is rotatably mounted on the frontend side arm 13 in the vertical direction, as shown in FIG. 1. The disc spring washer 170 produces the frictional resistance between the bearingparts 164, 164 and the bearingparts 131, 131 and the force that thetorsion coil spring 166 pushes the bearingparts 164, 164 to rotate upward relative to the bearingparts 131, 131 The resultant force can keep the mountingbracket 16 and thefront side arm 13 at any angle in the up-down direction, therefore, the (front) direction of thebase plate 15 can be adjusted to any angle in the up-down direction and held at any angle .

另外,如图10所示,在该监视器臂1中,由于附设有锁定装置8,因此,能够更可靠地固定基座板15的转动角度。在这种情况下,如图10以及图11所示,在拉动锁定装置8的手柄833并使一对销831脱离两处的锁定槽81、81的状态下,调节基座板15的转动角度,若放开手柄833,则一对销831在与该转动角度对应的位置处插入两处的锁定槽81、81内,并通过其卡合,限制基座板15的转动方向的运动,并固定保持转动角度。另外,在本实施例中,由于在前端侧臂13的一对轴承部131上以10°角度间隔形成有多个锁定槽81,因此,基座板15能够以10°角度间隔进行角度调节。In addition, as shown in FIG. 10 , since thelock device 8 is attached to the monitor arm 1 , the rotation angle of thebase plate 15 can be more reliably fixed. In this case, as shown in FIGS. 10 and 11 , the rotation angle of thebase plate 15 is adjusted in a state where thehandle 833 of thelocking device 8 is pulled and the pair ofpins 831 are disengaged from the two lockinggrooves 81, 81. , if thehandle 833 is released, a pair ofpins 831 are inserted into the two lockinggrooves 81, 81 at positions corresponding to the rotation angle, and through their engagement, the movement of thebase plate 15 in the rotation direction is restricted, and Fixed to maintain the rotation angle. In addition, in this embodiment, since a plurality of lockinggrooves 81 are formed at 10° angular intervals on the pair of bearingportions 131 of the frontend side arm 13 , thebase plate 15 can be adjusted angularly at 10° angular intervals.

另外,如图11所示,在该监视器臂1中,基座板15在安装托架16的前表面,可以以螺栓153为中心转动,此外,如图10所示,能够通过设置在基座板15背面侧的两个螺旋式止动件9来固定保持该基座板15的转动角度。在这种情况下,对于各个止动件主体91而言,通过以向基座板15的背面送进螺纹轴911的方向使旋钮913转动,接触部件912推压接触基座板15的背面以限制其沿转动方向的运动,另一方面,通过沿相反方向使旋钮913转动,接触部件912离开基座板15,以允许其转动。所以,在松缓各个止动件9的状态下,使基座板15任意转动,在决定转动角度之后,若旋紧各个止动件9,则能够固定保持其转动角度。In addition, as shown in FIG. 11, in this monitor arm 1, thebase plate 15 can rotate around thebolt 153 on the front surface of the mountingbracket 16. In addition, as shown in FIG. Twohelical stoppers 9 on the back side of theseat plate 15 are used to fix the rotation angle of thebase plate 15 . In this case, for each stoppermain body 91, by turning theknob 913 in the direction of feeding the threadedshaft 911 to the back surface of thebase plate 15, thecontact member 912 pushes into contact with the back surface of thebase plate 15 to thereby Its movement in the direction of rotation is restricted, on the other hand, by turning theknob 913 in the opposite direction, thecontact member 912 is separated from thebase plate 15 to allow its rotation. Therefore, thebase plate 15 is freely rotated in a state where eachstopper 9 is loosened, and after the rotation angle is determined, by tightening eachstopper 9, the rotation angle can be fixed and maintained.

这样,通过该监视器臂1,能够将监视器长期、稳定地保持在使用者所希望的位置处。另外,在改变监视器的设置位置的情况下,朝与上述规定方向相反的方向倾斜操纵各根杆6,以解除推压部件51与锁定部52的卡合,由此能够通过螺旋弹簧53的作用,自动解除各个臂11、12、13之间的锁定。接着,再次通过固定侧以及可动侧的各个定位导引件3、4,使各个臂11、12、13相互朝左右方向(或上下方向)转动,并在调节到任意的转动角度之后,通过朝规定方向倾斜操纵各根杆6,可以将各个臂11、12、13之间锁定在任意的转动角度。通过解除由锁定装置8、止动件9形成的固定状态,可以适当地调节基座板15的方向、转动角度,其后,只要通过锁定装置8、止动件9同样地固定基座板15即可。In this manner, the monitor arm 1 can stably hold the monitor at a position desired by the user for a long period of time. In addition, when changing the installation position of the monitor, eachlever 6 is tilted in a direction opposite to the above-mentioned predetermined direction to release the engagement of the pressingmember 51 and the lockingportion 52, whereby the force of thecoil spring 53 can be adjusted. The function automatically releases the locking between thearms 11, 12, 13. Next, eacharm 11, 12, 13 is rotated to the left and right direction (or up and down direction) through eachpositioning guide member 3, 4 on the fixed side and the movable side again, and after being adjusted to an arbitrary rotation angle, through Eachrod 6 is tilted and manipulated in a prescribed direction, and eacharm 11, 12, 13 can be locked at any rotation angle. By releasing the fixed state formed by thelock device 8 and thestopper 9, the direction and rotation angle of thebase plate 15 can be adjusted appropriately, and thereafter, thebase plate 15 can be fixed in the same way by thelock device 8 and thestopper 9. That's it.

如以上说明的那样,通过该监视器臂1,能够将各个臂11、12、13调节到任意的角度,并能够牢固地固定这些臂。特别是,即使在易于受到振动影响的车辆驾驶室内,仍能够长期稳定地将监视器保持在使用者所要求的规定位置处。另外,由于通过杆6的转动操作,能够自动解除各个臂11、12、13之间的锁定,因此,也能够容易地进行各个臂11、12、13之间角度的变化调节。As described above, with this monitor arm 1 , therespective arms 11 , 12 , and 13 can be adjusted to arbitrary angles, and these arms can be firmly fixed. In particular, it is possible to stably hold the monitor at a predetermined position requested by a user for a long period of time even in a vehicle cab which is easily affected by vibration.
