この考案は、キャスター付脚台の固定装置に関するものである。 The present invention relates to a fixing device for a footrest with casters.
【0002】[0002]
従来、テーブルや机に設けたキャスター付脚台をキャスターが機能しないよう に固定する場合、例えば該脚台に下方からねじ込んだアジャスタを回動してその 上下の突出量を調整して床面に押圧させている。しかし、このようなアジャスタ 機構では床面に押圧させるまでその回動に時間がかかり、操作性が悪いものであ った。 Conventionally, when fixing a foot stand with casters provided on a table or a desk so that the casters do not function, for example, an adjuster screwed into the foot stand from below is turned to adjust the amount of protrusion above and below the floor surface. It is pressing. However, in such an adjuster mechanism, it takes a long time to rotate until it is pressed against the floor surface, and the operability is poor.
【0003】[0003]
そこで、この考案は前記従来の問題点を解決し、例えば操作者が足で踏み込む というワンタッチ操作で簡単にキャスター付脚台を固定することができる装置を 提供することを目的とする。 Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a device that can easily fix the footrest with casters by, for example, a one-touch operation in which the operator steps on the foot.
【0004】[0004]
前記目的を達成するため、この考案は、テーブルや机に設けられるキャスター 付脚台の固定装置であって、上面に脚台に設けた貫通穴と連通する開口部を有し 、かつ下面に開口部を有して該脚台の裏面に取付けられる中空のケースと、この ケースの一端側の下部にその下面開口部を下方から覆うように枢支軸により上下 方向に揺動可能に枢支された本体部及び該本体部の下部に第1付勢部材により下 方に付勢されて設けられた脚部からなる固定体とを具えている。ケース内にその 上面開口部を経て脚台の貫通穴から突出する頭部及び下面開口部から固定体の本 体部に当接する突部を摺動部に有する摺動部材を上下方向に摺動自在に収納して いる。摺動部材の頭部が脚台の貫通穴から常時突出するように固定体を付勢する 第2付勢部材を枢支軸に介装している。摺動部材の摺動部に長穴を形成し、この 長穴にガイドピンを摺動部材の摺動方向と交叉する方向に摺動自在に装着してい る。ガイドピンが長穴を摺動することによってその先端部が係合しまたは係合が 外れる係合部を有するガイドピン用案内凹溝をケースの相対向する内面に形成し ている。この案内凹溝の係合部は、脚台の貫通穴から突出した摺動部材の頭部を 押下して摺動部材を下方に摺動するとともに、摺動部材の突部で固定体を第2付 勢部材の付勢力に抗して下方へ揺動し、固定体の脚部が床面を押圧して第1付勢 部材の付勢力に抗するようになると、ガイドピンが係合し、この係合状態でさら に摺動部材の頭部を押下して摺動部材を下方に摺動すると、ガイドピンの係合が 外れる位置に形成されている。 In order to achieve the above-mentioned object, the present invention is a fixing device for a foot stand with casters provided on a table or a desk, having an opening on the upper surface that communicates with a through hole provided on the foot stand, and an opening on the lower surface. A hollow case that is attached to the back surface of the pedestal and has a lower end on one end side of the case that is pivotally supported in a vertical direction by a pivot shaft so as to cover the lower surface opening from below. And a fixed body composed of a leg portion which is urged downward by a first urging member and which is provided below the main body portion. A sliding member that has a head that protrudes from the through hole of the pedestal through the top opening in the case and a protrusion that contacts the main body of the fixed body from the bottom opening in the sliding part slides up and down. It is stored freely. A second urging member for urging the fixed body is interposed on the pivot shaft so that the head of the sliding member always projects from the through hole of the pedestal. An elongated hole is formed in the sliding portion of the sliding member, and a guide pin is slidably mounted in the elongated hole in a direction intersecting the sliding direction of the sliding member. Guide pin guide grooves are formed on the inner surfaces of the case that face each other, the guide pin having an engaging portion that engages or disengages at its tip end as the guide pin slides in the elongated hole. The engaging portion of the guide groove pushes down the head of the sliding member protruding from the through hole of the pedestal to slide the sliding member downward, and the protruding portion of the sliding member moves the fixed body to the first position. 2 When the leg of the fixed body presses the floor surface against the biasing force of the first biasing member by swinging downward against the biasing force of the biasing member, the guide pin engages. When the head of the sliding member is further pushed down in this engaged state to slide the sliding member downward, the guide pin is disengaged.

脚台を固定するには、脚台の貫通穴から突出した摺動部材の頭部を押下する。 この押下により摺動部材がケースの収納室内を下方に摺動し、その突部の先端で 本体部が押圧される固定体が第2付勢部材の付勢力に抗して下方に揺動されると ともに、ガイドピンが長穴内を摺動しながら案内凹溝内を摺動し、固定体の脚部 が床面を押圧して第1付勢部材の付勢力に抗するようになると、ガイドピンが係 合部に係合するに至る。これにより脚台は、第1付勢部材の付勢力を受ける脚部 によって固定された状態となる。一方、再び、非固定の状態にするには、摺動部 材の頭部を一旦、押下して摺動部材を下方に摺動し、ガイドピンを係合部から外 す。しかる後、押下をやめると、固定体が第2付勢部材の付勢力を受けて上方に 揺動し、この揺動に伴い摺動部材も上方に摺動するとともに、ガイドピンが長穴 内を摺動しながら案内凹溝内を摺動し、固定体の脚部が床面から離れてキャスタ ーより上方の位置となると、脚台は元の非固定状態となる。 To fix the footrest, the head of the sliding member protruding from the through hole of the footrest is pressed. By this depression, the sliding member slides downward in the housing chamber of the case, and the fixed body whose main body is pressed by the tip of the protruding portion swings downward against the urging force of the second urging member. At the same time, the guide pin slides in the guide groove while sliding in the oblong hole, and the legs of the fixed body press the floor surface to resist the urging force of the first urging member. The guide pin reaches the engaging portion. As a result, the leg base is fixed by the leg portion that receives the biasing force of the first biasing member. On the other hand, to return to the non-fixed state, the head of the sliding member is once pushed down to slide the sliding member downward, and the guide pin is disengaged from the engaging portion. After that, when the pressing is stopped, the fixed body receives the urging force of the second urging member and oscillates upward. With this oscillating motion, the sliding member also slides upward, and the guide pin moves in the elongated hole. When the legs of the fixed body move away from the floor and are located above the casters while sliding in the guide groove while sliding, the pedestal is in its original non-fixed state.
