を載置するテーブル台の昇降装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevating device for a table on which a peripheral device such as a computer is placed.

ていた。 Conventionally, there has been a lifting device used for a table stand as disclosed in Japanese Patent Application Laid-Open No. 54-97156. In this device, a hollow movable leg member is fitted and held in each of two hollow left and right fixed leg members so as to be able to move up and down, and a screw shaft is suspended from the top of the movable leg member. A female screw body fixed to the fixed leg member side is screwed onto the screw shaft. Further, a top plate serving as a table base is fixed to the top of the movable leg member, and a link mechanism for interlocking the left and right screw shafts is arranged on the lower surface of the top plate. This link mechanism includes a link fixed to the upper end of each of the left and right screw shafts, and a connecting plate that connects the free ends of these links. It is supported in such a manner that the movement and the push/pull movement along the longitudinal direction are performed in parallel. Then, the link fixed to either one of the left and right screw shafts is directly rotated by the operation lever, and the rotation is transmitted to the link fixed to the other screw shaft via the connecting plate. I was getting used to it.
このような昇降装置によると、操作レバーを回
転操作することにより左右のねじ軸を同一速度で
同一量だけ回転させることができ、上記天板の昇
降を円滑に行わせ得るところから高い技術的評価
を得ている。 According to such a lifting device, by rotating the control lever, the left and right screw shafts can be rotated by the same amount at the same speed, and the above-mentioned top plate can be smoothly raised and lowered, which has led to high technical evaluation. I am getting .
しかしながら、上記昇降装置に用いられている

するねじ軸は高価であり、ねじの向きが逆になつ
ているねじ軸を一本ずつ用意することは昇降装置
のコスト高につながる。また、昇降装置の製作時
にねじ軸を組み違えるおそれもある。 However, the link mechanism used in the above-mentioned lifting device consists of a single connecting plate that is supported in a state in which a swinging motion with the longitudinal intermediate portion as a fulcrum and a push/pull motion along the longitudinal direction are performed in parallel. Therefore, since the rotation of one link is transmitted to the other link, the rotation directions of these two links are always opposite. Therefore, it is essential that the screw directions of the left and right screw shafts to which these links are fixed are opposite to each other. You must prepare one screw shaft at the bottom. However, compared to the commonly used screw shafts with threads in the forward direction, screw shafts with threads in the opposite direction are more expensive, and it is necessary to prepare each screw shaft with the threads in the opposite direction. This leads to higher costs for the lifting device. Furthermore, there is a risk that the screw shafts may be assembled incorrectly when manufacturing the lifting device.
さらに上記昇降装置では、固定脚部材側に雌ね

れを行いにくい。 Furthermore, in the above-mentioned lifting device, the female screw body is fixed to the fixed leg member side, so when the screw shaft is rotated by operating the operating lever, the screw shaft moves up and down, and the operating position of the operating lever moves up and down. do.
This makes it difficult to operate the control lever, and at the same time, it is difficult to change the design from a manual type to an electric type.

提供することを目的とする。 This idea was made in view of the above circumstances.
The purpose of this is to connect the left and right screw shafts by a link mechanism equipped with a connecting plate that performs both the rocking motion and the push/pull motion as described above. To provide an elevating device that can be manufactured using only the same screw shaft, the operating position of an operating lever does not move during elevating and lowering operations, and the design can be easily changed to an electric type. With the goal.

せて構成されている。 Each of the screw shafts 7 is rotatable by rotating the operating levers 1, 1. That is, one rotation shaft 18 on which the operating levers 1, 1 are provided
intersects with this one rotating shaft 18 and the screw shaft 7
Each threaded shaft 7 is made rotatable via a rotation force transmission mechanism B between it and the other rotation shaft 19 to which a link mechanism 10 for rotating the threaded shafts 7 is connected. This rotational force transmission mechanism B includes a first rotational force transmission mechanism B in which an appropriate number of locking protrusions 20 (eight in this embodiment) are formed along the outer circumference of the disc on one rotational shaft 18 provided with the operating levers 1, 1. A transmission plate 21 is provided, and a locking hole 2 that can freely engage with the locking protrusion 20 formed on the first transmission plate 21.
A second transmission plate 23, in which a second transmission plate 23 is arranged along one concentric circle, is provided on the other rotation shaft 19 that intersects at right angles with one rotation shaft 18 on which the operation levers 1, 1 are provided, and By rotating the levers 1, 1, the first transmission plate 21 is rotated and at the same time, the second transmission plate 23 is rotated. As shown in FIG. 5, the link mechanism 10 has a driven link 24 of the same shape at the upper end of each screw shaft 7.
One end of the driving link 25, which has the same shape as the driven link 24, is fixed to the rotating shaft 19, which is connected from the operating levers 1, 1 through the rotating force transmission device B. One end of connecting plates 26, 27 having different lengths are pivotally connected to the other ends of links 24, 24, and both connecting plates 26, 27
The other ends of the drive link 25 are pivotally connected 30 to the other ends of the drive link 25, and elongated holes 26a and 27a formed in the center of the longitudinal direction of the connecting plates 26 and 27 are fixed to the reinforcing beam 6, respectively. It is configured to be inserted and supported by shafts 31 and 32.

上方又は下方へ螺送せしめられる。 Therefore, when the operating levers 1, 1 are rotated in one direction, the connecting plates 26, 27 are rotated in the direction of the arrow (longitudinal direction) as the driving link 25 is rotated via the rotation force transmission device B. The driven links 24 are pushed and pulled along the same axis, and are also oscillated around the support shafts 31 and 32, whereby each driven link 24 is rotated by the same amount in the same direction, and each screw shaft 7... The female threaded body 15 is screwed upward or downward.
このように操作レバー１，１を回動操作するだ

ており、保守や修理が容易にできる。 With this configuration, the screw shaft 7 can be provided facing the fixed leg member 5, and the fixed leg member 5 and the movable leg member 13 fitted into the fixed leg member 5 can be formed in the minimum necessary shape. It is economical because it can be used with certain dimensions. Further, the connection between the screw shaft 7 and the movable leg member 13 can be achieved by screwing the female thread body 15 onto the screw shaft 7 and then fixing the female screw body 15 to the movable leg member 13. The lifting device can be manufactured with the 15 cores aligned. This makes it possible to ensure alignment of the female threaded body 15 with respect to the screw shaft 7 and to facilitate assembly. Furthermore, the screw shaft 7 and the female screw body 15
are provided opposite to the fixed leg member 5 and the movable leg member 13, so when the cover body 33 is removed, the screw shaft 7 and the female thread body 15 are exposed, making maintenance and repair easy. can.

することが可能である。 As explained above, the lifting device of the present invention is
Since it can be constructed using two screw shafts with the screws in the same direction, there is no room for mis-assembly of the screw shafts, and cost reduction is achieved by using a commonly used screw shaft with screws in the forward direction. can be achieved. Furthermore, the rotation of the screw shaft only moves the movable leg member up and down together with the female threaded body screwed onto the screw shaft, and the link mechanism having the driving link does not move. Therefore, when using a manual type, the operability is improved. Furthermore, the design can be easily changed to an electric type.
