The universal caster according to claim 1 is rotatably connected to a mounting seat attached to a carriage or the like, and includes a rotating wheel having a mounting wheel mounting frame. A stop body is attached, a lifting member that can be lifted and lowered via a bearing body is attached to the wheel mounting frame, a claw body that engages with the irregularities formed on the periphery of the stop body is attached to the lifting member, and a wheel is attached to the lifting member. The body is rotatable, a support member is provided on the operating member, and the operating member is connected to the arm.
Then, by rotating the arm, by raising and lowering the elevating member via the actuating member and the support member, the rotation of the wheel is brought into a locked state and an unlocked state by the claw body and the stop body. To do.
又、請求項２の自在キャスターは、バネによって、前記アームと作動部材を介して昇降部材を降下させてロック状態とし、前記アームに連結のワイヤーを引っ張ることによって、前記アームの回動により、前記作動部材を介して昇降部材を上昇させてアンロック状態にする。 According to a second aspect of the present invention, the swivel caster is configured such that the lifting member is lowered by the spring via the arm and the operating member to be in a locked state, and a wire connected to the arm is pulled to rotate the arm. The elevating member is raised through the actuating member to be in an unlocked state.
本発明の自在キャスターのロック機構は、簡便な構成である。 The lock mechanism of the universal caster of the present invention has a simple configuration.
本発明の実施の形態について、一例示として台車等に取付ける自在キャスターのロック状態である正面を示す図１、図１の右側面を示す図２、図１の平面を示す図３、アンロック状態である正面を示す図４、図４の右側面を示す図５を参照して説明する。 FIG. 1 shows a front view in a locked state of a free caster attached to a carriage or the like, FIG. 2 shows a right side of FIG. 1, FIG. 3 shows a plan view of FIG. 4 showing the front, and FIG. 5 showing the right side of FIG.
箱状の取付座２には、台車の台板（図示略）の下に取付ける取付体３を備えている。この取付座２の中心には、昇降部材５を嵌合する軸受け体６が取付けてあり、昇降部材５の昇降を可能にする。
また、前記取付座２には、左右一対のフォーク８を備える車輪取付け枠９がベアリング１０を介して取付けてあり、車輪取付け枠９は取付座２に対して回動可能であり、車輪１５の旋回が可能である。
前記一対のフォーク８の下部にはシャフト１２が横架されていて、ベアリングを介して回転して走行可能な車輪１５が取付けてある。
又、前記シャフト１２には、車輪１５に併設して、周縁に凹凸を形成の停止体１８が取付けてある。
The box-shaped mounting seat 2 includes a mounting body 3 that is mounted under a base plate (not shown) of the carriage. At the center of the mounting seat 2, a bearing body 6 that fits the elevating member 5 is attached, and the elevating member 5 can be raised and lowered.
A wheel mounting frame 9 having a pair of left and right forks 8 is mounted on the mounting seat 2 via a bearing 10, and the wheel mounting frame 9 is rotatable with respect to the mounting seat 2. Turn is possible.
A shaft 12 is horizontally mounted at the lower part of the pair of forks 8, and a wheel 15 capable of rotating and running through a bearing is attached.
Further, the shaft 12 is provided with a stop body 18 which is provided with a wheel 15 and has irregularities on its periphery.
前記昇降部材５の下端には、前記停止体１８と歯合する爪体２０が支持枠２２を介して取付けてあり、その上部には、昇降部材５の回転を制止する制止体２１が、前記昇降部材５を相通して、一対のフォーク８に横架してある。従って、車輪１５の旋回と共に停止体１８と昇降部材５（爪体２０）が回動するので、いずれの方向に車輪が向いていても、停止体１８と爪体２０は歯合が可能である。 A claw body 20 that meshes with the stop body 18 is attached to the lower end of the elevating member 5 via a support frame 22, and a restraining body 21 that inhibits the rotation of the elevating member 5 is provided on the upper portion thereof. The elevating member 5 is connected to the pair of forks 8. Accordingly, since the stop body 18 and the elevating member 5 (claw body 20) rotate as the wheel 15 turns, the stop body 18 and the claw body 20 can be engaged with each other regardless of the direction of the wheel. .
前記取付座２の側部には、ワイヤー２５の停止体２６が取付けてあり、ワイヤー２５に取付の接続具２７で停止される。このワイヤー２５の端部は、連結体３０に結合してある。この連結体３０の他端部は、アーム３１の端部に回動可能に結合してあり、このアーム３１の他端部は作動部材３５に結合してある。従って、前記連結体３０を介して、アーム３１の揺動により、前記作動部材３５も同じく回動する。 A stop body 26 of the wire 25 is attached to the side portion of the mounting seat 2, and is stopped by a connecting tool 27 attached to the wire 25. The end of the wire 25 is coupled to the connecting body 30. The other end of the coupling body 30 is rotatably coupled to the end of the arm 31, and the other end of the arm 31 is coupled to the operating member 35. Therefore, the operating member 35 is also rotated by the swing of the arm 31 via the connecting body 30.
又、前記アーム３１を図２において、反時計方向に引っ張るバネ４０が、取付座２とアーム３１の軸に取付けてあり、常時、昇降部材５を降下状態に、即ち、爪体２０が停止体１８に歯合してロック状態としている。尚、前記作動部材３５は、取付座２に回動可能に取付けてある。 A spring 40 for pulling the arm 31 counterclockwise in FIG. 2 is attached to the shaft of the mounting seat 2 and the arm 31, and the elevating member 5 is always in the lowered state, that is, the pawl body 20 is a stop body. 18 is in a locked state. The actuating member 35 is rotatably attached to the mounting seat 2.
又、前記作動部材３５には、前記昇降部材５の両側に、支持部材３７が取付けてある。一方、前記昇降部材５の上部には細軸が形成してあり、その細軸に前記一対の支持部材３７に横架の昇降軸３８を取付けの輪体３９が回転可能に、ワッシャ３９ｂを介してボルト３９ａで取付けてある。従って、回動する作動部材３５によって、支持部材３７と昇降軸３８を介して、昇降部材５は昇降すると共に、昇降部材５は回動可能である。 Support members 37 are attached to the operating member 35 on both sides of the elevating member 5. On the other hand, a thin shaft is formed in the upper part of the elevating member 5, and a ring 39 having a horizontal elevating shaft 38 attached to the pair of support members 37 on the thin shaft is rotatable via a washer 39b. Are attached with bolts 39a. Therefore, the raising / lowering member 5 is raised and lowered by the rotating operation member 35 via the support member 37 and the raising / lowering shaft 38, and the raising / lowering member 5 is rotatable.
次に、前記構成の自在キャスターの車輪が走行可能な回転をロックするロック機構の作用について説明する。
図１は、バネ４０によって、昇降部材５を降下状態に維持し、爪体２０が停止体１８に歯合してロック状態であり、車輪１８の回転は制止され、安全な停止状態を維持できる。
Next, the operation of the lock mechanism that locks the rotation at which the wheels of the swivel caster having the above structure can travel will be described.
In FIG. 1, the elevating member 5 is maintained in the lowered state by the spring 40, the claw body 20 is engaged with the stop body 18, is locked, the rotation of the wheel 18 is stopped, and a safe stop state can be maintained. .
一方、図４、図５はアンロック状態を示す図であり、ワイヤー２５を引っ張ると、前記連結体３０を介してアーム３１が時計方向に回動する。このアーム３１の回動によって、作動部材３５が回動し、支持部材３７と昇降軸３８を介して、昇降部材５は昇降する。この昇降部材５の上昇により、爪体２０は停止体１８から離脱して、アンロック状態になる。このアンロック状態になると、車輪１８は自由に回転できて走行可能である。又、昇降部材５は輪体３９に対して回転可能であるので、車輪取付け枠９に取り付けのフォーク８が回動自在、即ち、車輪１５が旋回可能であるので、方向を容易に変更できる。従って、アンロック状態になると、従来の自在キャスターとして機能する。 On the other hand, FIGS. 4 and 5 are diagrams showing an unlocked state. When the wire 25 is pulled, the arm 31 is rotated clockwise through the connecting body 30. The operation member 35 is rotated by the rotation of the arm 31, and the elevating member 5 is moved up and down via the support member 37 and the elevating shaft 38. As the elevating member 5 is raised, the claw body 20 is detached from the stop body 18 and becomes unlocked. In this unlocked state, the wheel 18 can freely rotate and travel. Further, since the elevating member 5 is rotatable with respect to the wheel body 39, the fork 8 attached to the wheel mounting frame 9 is rotatable, that is, the wheel 15 is turnable, so that the direction can be easily changed. Therefore, when it is unlocked, it functions as a conventional free caster.
尚、前記はワイヤーを介してアーム３１を回動してアンロック状態にする構成であるが、リンク機構やレバー等を介して前記アーム３１を回動する構成であってもよい。 In addition, although the said is the structure which rotates the arm 31 via a wire and makes it an unlocked state, the structure which rotates the said arm 31 via a link mechanism, a lever, etc. may be sufficient.
