ることができる装置の構造に関するものである。[Detailed description of the invention] [Field of industrial application] This invention is a study desk, a drafting desk, an OA desk, various tables, etc., whose top plates are attached to the legs so that they can be adjusted vertically. The invention relates to the structure of an apparatus that can balance the supporting force according to variations in the top plate and the weight thereon.

When adjusting the top of the table so that it can move up and down, in order to prevent the top from tilting to the left or right with respect to the legs, and to reduce the force required to raise the top when adjusting the top to move up and down, Actual practice of prior art 1977-
In Publication No. 811, left and right columns protruding downward from both left and right sides of the lower surface of the top plate are fitted into the left and right legs so as to be vertically movable, and a set of three left and right columns are installed at the top and bottom of each of the left and right columns. A pair of guide wheels is provided, two flexible wrapping bodies are wound around these guide wheels in a so-called endless shape, a part of the wrapping bodies is fixed to the leg body, and a part of the wrapping body is connected to this wrapping body. A structure is disclosed in which the support column is biased in the direction of lifting by the force of the spring.
この構成によれば、天板の重量等とスプリング
の付勢力との差だけ上昇に要する力が軽減され

勢力を軽い状態の天板等の重量にバランスさせて
いると、天板等の重量が大きくなつた場合には、
上昇力の軽減の効果が極めて少なくなる。
According to this configuration, the force required for lifting is reduced by the difference between the weight of the top plate and the biasing force of the spring. However, when a heavy item such as a bookshelf is removably mounted on the top plate, the supporting force to be supported may be large depending on whether the bookshelf is placed on it or not, and the weight of the books, etc. placed on the bookshelf. Therefore, if the biasing force of the spring is balanced with the weight of the top plate in a light state as in the prior art, if the weight of the top plate etc. increases,
The effect of reducing the climbing force becomes extremely small.
さらに、支柱の昇降量を大きくとる必要がある
場合には、前記スプリングの付勢力が大きいスト
ロークにわたつて作用できるようにしなければな
らないにもかかわらず、このスプリングを巻掛け
体の１箇所に連結するものでは実質上不可能であ
ると云う問題があつた。 Furthermore, when it is necessary to increase the amount of elevation of the support column, the spring must be connected to one point on the wrapping body, even though the biasing force of the spring must be able to act over a large stroke. The problem was that it was virtually impossible to do so.
そこで本考案では、机等における左右一対の脚

Therefore, in the present invention, the upper ends of a pair of left and right legs of a desk, etc. are connected by a horizontal member, and on the left and right legs, columns projecting downward on both the left and right sides of the bottom surface of the top plate of the desk, etc. are connected, and each of the legs is vertically movable. mounted on the horizontal member,
The proximal end of the lever is pivotally mounted for substantially horizontal rotation, and a cable having one end connected to the lower end of the one pillar is connected to the other end of the lever via a group of pulleys disposed on the horizontal member. On the other hand, the other end of a biasing means such as a gas spring whose one end is horizontally rotatably pivoted to the horizontal member is attached to the lever so as to bias the support column upward, and the other end of the biasing means is attached to the lever. The lever is configured to be attached so that the distance from the base pivot point of the lever can be adjusted.
このように、本考案では、左右両脚体の上端部
間を連結する横部材に水平回動自在に枢着された
レバーと、支柱の下端とを索条及び滑車群を介し
て連結するものである。
In this way, the present invention connects the lever, which is horizontally rotatably pivoted to the horizontal member that connects the upper ends of the left and right legs, and the lower end of the column through the cable and pulley group. be.
即ち、この滑車群は横部材に固定されるいわゆ
る固定滑車と、前記回動レバーに連結されて当該
レバーと共に移動するいわゆる動滑車から成り、
これらの滑車の数と索条の巻掛け方式は従来公知
の種々のものがある。 That is, this pulley group consists of a so-called fixed pulley that is fixed to the horizontal member and a so-called movable pulley that is connected to the rotary lever and moves together with the lever.
There are various known numbers of pulleys and various cable wrapping methods.
従つて、動滑車と固定滑車との組み合わせによ
る滑車群の数に応じてこれらの滑車の作用によ

リング等の付勢手段の付勢力もそれだけ小さくで
き、付勢手段の構造も簡単且つ小型化することが
できると共に支柱を任意高さ位置にてロツクする
装置も簡単なものにすることができる。 Therefore, depending on the number of pulley groups that are a combination of movable pulleys and fixed pulleys, the weight of the support column and even the top plate, etc. is not directly transmitted to the lever, but is transmitted by one-half or one-third of the weight by the action of these pulleys. 1, 4
Since the power is transmitted to the lever in a state that is reduced to one-fold, the biasing force of the biasing means such as a gas spring connected to the lever can be reduced accordingly, and the structure of the biasing means is also simple and compact. In addition, the device for locking the column at an arbitrary height can be simplified.
さらに、前記滑車群を用いると、所定の支柱の
昇降量に対して、レバーの回動量を少なくするこ
とができ、これに連結して支柱を上向きに付勢す

て、装置全体をコンパクトなものにすることがで
きる。 Furthermore, by using the pulley group, the amount of rotation of the lever can be reduced relative to the amount of elevation and descent of the predetermined column, and the stroke amount of the biasing means connected thereto to urge the column upward can be reduced. It can be made small, and therefore the entire device can be made compact.
しかも、支柱を上向きに付勢手する付勢手段と

ことにより、いわゆるてこの原理によつて前記付
勢手段の付勢力を同じにしたまま、天板等の重量
とバランスさせることができるのである。 In addition, the connection point between the biasing means for biasing the support column upward and the pivot lever is configured so that the distance can be freely adjusted with respect to the pivot point of the lever, so that the weight of the top plate, etc. is reduced. If the weight of the top plate, etc. changes, the connection point between the biasing means and the rotating lever is changed accordingly, so that the weight of the top plate, etc. It is possible to balance it.

なく、円滑に上下動することができる。 According to this configuration, when the lock device (not shown) is released and the top plate 1 is pulled upward, the lower guide wheels 19a, 19b at the lower ends of both the left and right columns 2, 2'
and upper guide wheels 21c, 2 at the upper part of the legs 3, 3.
The vertical distance from 1d is shortened and the cable 1 in that part is shortened.
7, 18 try to relax, but these cables 17,
The vertical distance between the locking portions 23, 23, to which the other ends of the cables 18 are locked, and the upper guide wheels 21a, 21d becomes longer, and the cables 17, 18 are pulled. The tensions of the strips 17 and 18 are balanced on both the left and right sides as they move. Therefore, both the left and right columns 2, 2' can be raised and lowered by the same amount, and the top plate 1 above them can also be smoothly moved up and down without tilting to the left or right.

り、下降させることができる。 In this way, the top plate 1 is moved up and down by the cables 11 and the pulley group 15 in the weight balance support device 10.
The load is transmitted to the lever 13 in a reduced state, while the supporting column 2 is urged upward by the urging force of the gas spring 14 installed between the lever 13 and the horizontal member 4, and the urging force of the gas spring 14 and the above-mentioned The weight of the column 2 and the top plate 1 etc. can be supported with a light force due to the difference in force from the reduced load, and when the biasing force of the gas spring 14 is brought close to the reduced load, the top plate Since it is supported while balancing the load, it can be raised or lowered with a light force.

い。 In the present invention, the position of the point of application of the urging force of the gas spring 14 with respect to the lever 13 can be adjusted telescopically, so even if the load of the book stand 6 placed on the top plate 1 fluctuates, the point of application of the gas spring 14 can be adjusted telescopically. You can easily balance the weight by simply changing the position.
It goes without saying that the biasing means can be a coil spring instead of a gas spring.
