Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes a pedestal having at least three legs, an outer pipe projecting vertically from a central portion of the pedestal, and an axial movement with respect to the outer pipe for height adjustment. The present invention relates to a tool support stand that includes an inner pipe, lock means for locking the inner pipe with respect to the outer pipe, and a tool support head fixed to the top of the inner pipe.
[0002]
[Prior art]
Examples of such a tool support stand include a medical tool support stand such as a drip liquid storage bag or a bottle, or a microphone support stand. Regarding the locking means for these tool support stands, loosen the clamping sleeve or clamping screw between the outer and inner pipes to adjust the height of the insertion / removal, and then tighten the clamping sleeve or clamping screw again at the adjustment position to lock it. There is something to do.
[0003]
[Problems to be solved by the invention]
For example, in a conventional device support stand such as a drip solution storage bag or a bottle, to adjust the height of insertion / extraction of the inner pipe, hold the inner pipe with one hand and hold the clamping sleeve or the clamping screw with the other hand. It is necessary to loosen and raise and lower the inner pipe to the desired height with one hand, and finally tightening with the other hand at the adjusted height is required.
[0004]
However, one arm of a patient receiving an infusion has an instillation needle inserted therein, and it is troublesome and difficult for the patient himself to adjust the height of the support stand of the infusion bag or the bottle using both hands.
[0005]
Therefore, an object of the present invention is to provide a tool support stand, particularly a drip solution that allows a nurse or doctor to easily adjust the height of the support stand with one hand, even for the patient who is receiving the drip. The object is to obtain a tool support stand such as a container or a microphone support stand.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the tool support stand of the present invention comprises:
The locking means;
A core rod concentrically disposed in the outer pipe, the core rod having the lower end of the core rod fixed to the lower end of the outer pipe; and
A mesh sleeve is slidably fitted around the core bar, and a sliding bush is connected to each of the lower and upper ends, and the mesh sleeve is connected between the lower and upper sliding bushes. A mesh sleeve means for extending and contracting the mesh sleeve by a coil spring arranged around, the mesh sleeve flatly gripping and holding the core bar, and the lower sliding bush fixed to the lower end of the inner pipe;
A spacer tube which is inserted into the core rod above the upper sliding bush and loosely fitted in the inner pipe;
An operation sleeve provided around the inner pipe in the vicinity of the upper end of the inner pipe, and a cross pin penetrating through an elongated elongated hole in the axial direction provided in a position opposed to each other in the diametrical direction in the vicinity of the upper end of the inner pipe. It is connected to the inner pipe so as to be movable in the axial direction within a limited range, and in the no-load state, it moves to the lower limit position under gravity so that the cross pin contacts the upper end surface of the spacer tube at the lower limit position. It is characterized by comprising an operating sleeve.
[0007]
According to the locking means of the tool support stand of the present invention, there is no need to provide a conventional screw action clamping means. That is, when the inner sleeve is pulled out with respect to the outer pipe while holding the operation sleeve at the upper end of the inner pipe with one hand, the lower end sliding bush of the mesh sleeve means connected to the lower end of the inner pipe is fixed to the outer pipe. Slide upwards on top. As the lower sliding bush is slid upward, the mesh sleeve is gradually contracted, and the upper sliding bush is also slid upward on the core rod by the pressing force of the coil spring. When the operating sleeve is released, the mesh sleeve is expanded and contracted again by the action of the coil spring at the position where the inner pipe is pulled out, and is brought into close contact with the core rod, and this state is maintained.
[0008]
When holding the operation sleeve with one hand and trying to retract the inner pipe into the outer pipe, the cross pin in the operation sleeve pushes down the upper sliding bush of the mesh sleeve against the force of the coil spring through the spacer tube. Thereby, the contraction of the mesh sleeve is loosened, and the mesh sleeve, the lower sliding bush, and the inner pipe slide downward along the core rod fixed to the outer pipe. Next, when the operation sleeve is released, the mesh sleeve is expanded and contracted again by the action of the coil spring, and is brought into close contact with the core bar and automatically stopped to maintain this state.
