Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a flask support device for a shaking culture vessel.

(Prior Art) In general, as a flask support device for a shaking incubator, for example, as shown in FIG. A type that presses down on the flask, or
As shown in FIG. 10, three claw clamps 105 are arranged in a ring shape on the top surface of the shaking table 101 in a standby position (indicated by chain lines) that opens outward, and a spring 107 is fitted to the upper end of the claw clamps 105. Typical examples include a type that holds down the flask, and a rack type that doubles as a shaking table and has a large number of lattice-shaped flask support chambers 111 as shown in FIG. 11. In addition,
In the rack type, the flask support chamber 111
Some partition walls are made of springs, rods, etc. instead of plates.

(Problems to be Solved by the Invention) As described above, in the case of the type shown in FIG. 9, when setting the flask, the three claw clamps 103 must be simultaneously expanded outward.
In this case, it is easy to spread the flasks with both hands, but since one hand is holding the flask, it is difficult to spread all three of them outward at the same time with one hand against the spring pressure of the claw clamp 103, which makes setting the flasks extremely difficult. My face was warm. In particular, claw clamp 10
If the spring pressure in step 3 is strong, someone who spreads it with both hands,
This is unfavorable in terms of workability, as it requires a person to set up the flask, which cannot be done by one person.

In addition, in the case of the type shown in FIG. 10, after setting the flask 109, while compressing the upper end of the claw clamp 105 in the standby position (dashed line) with one hand to the state shown by the solid line, use the other hand to compress the spring 107.
Even with this type, the work is difficult and undesirable in terms of workability.

Furthermore, in the case of the rack type flask 109 shown in FIG. 11, the upper end of the flask 109 is not fixed, so there is a risk that the upper end may tilt during shaking, causing problems such as the culture solution inside spilling out. For this reason, it cannot be used in a shaking incubator that shakes strongly, and the conditions of use are limited.

Therefore, the object of this invention is to provide a flask support device for a shaking incubator that eliminates the above-mentioned problems.

[Structure of the invention] (Means for solving the problem) In order to achieve the above object, in this invention, a plurality of clamp arms are arranged in a ring shape on the top surface of the shaking table, and a plurality of clamp arms are arranged in a ring shape on the top surface of the shaking table, and a hinge member is used. It is rotatably attached to the clamp arm in a holding position in which the flask is held down, and in a release position in which it opens outward at a predetermined angle of inclination. An arm extension is provided for rotating the clamp arm from the release position to the holding position by weight, and a holding ring is provided separately from the clamp arm to fit into the upper end of the clamp arm in the holding position.

(Function) According to such a flask support device, after the clamp arm is in the released position where it is opened outward, when the seat of the flask is placed on the arm extension, the weight of the flask causes the clamp arm to rotate from the released position to the holding position. The setting operation is then completed by fitting the retaining ring to the upper end of the clamp arm. This series of operations can be easily performed with one hand, and the upper end of the crank arm is securely held by the retaining ring.

(Embodiment) Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 6.

In the figure, reference numeral 1 indicates a shaking table that is reciprocated in a figure-eight or horizontal direction by a predetermined shaking means (not shown). On the top surface of the shaking table 1, clamp arms 3 are arranged in a ring shape at three locations (although four locations are also possible).

The clamp arm 3 has a shape that follows the body of the flask 5, and its lower end is rotatably attached to the upper surface of the shaking table 1 by a hinge 7. As a result, the clamp arm 3 is attached to the flask 5 as shown in FIG.
It becomes possible to switch between a holding position in which it is held down and a release position in which it opens outward at a predetermined angle of inclination α.

The upper end of the clamp arm 3 is a fitting part 11 into which the holding ring 9 is fitted when in the holding position.

The lower end of the clamp arm 3 is an arm extension 13 that projects further inward from the hinge 7.

The arm extension part 13 has a shape in which the free end side rises a predetermined distance from the upper surface of the shaking table 1 when the clamp arm 3 is in the released position in which it is opened outward. The lifting angle θ of the arm extension 13 is set so that when the arm extension 13 comes into contact with the top surface of the shaking table 1 due to the weight of the flask 5 placed on it, the clamp arm 3 rotates to a holding position. has been done.

The hinge 7 consists of a pair of movable parts 7b and 7c that can rotate about the hinge shaft 7a, one movable part 7c is attached to the upper surface of the shaking table 1, and the other movable part 7b is attached to the arm extension part from the hinge arm 3. 13, the movable part 7
b and the movable portion 7c overlap, the clamp arm 3 assumes a released position in which it opens outward, and functions as a stopper that holds the clamp arm 3 at a predetermined angle α.

In this case, instead of the hinge 7 having a stopper function, the clamp arm 3 is directly fixed to the rotating shaft 15 fixed to the top surface of the shaking table 1 as shown in FIGS. It is also possible to have a structure in which the stopper member 17 is fixed to the clamp arm 3 so as to be freely rotatable and to be positioned in the released position.

On the other hand, the retaining ring 9 that is fitted into the fitting portion 11 of the clamp arm 3 is formed into a ring shape from a metal or synthetic resin material. The inner circumferential surface of the retaining ring 9 is chamfered D to facilitate attachment and detachment, as shown in FIG. In this case, it is preferable to provide the fitting part 11 of the clamp arm 3 with a hook part 19 that engages with the chamfered part D, as shown in FIG.

According to the flask support device configured in this manner, the flask 5 is placed on the arm extension portion 13 after the clamp arm 3 is set to the released position in which it opens outward. As a result, the clamp arm 3 is attached to the flask 5.
The flask 5 is rotated from the release position to the holding position due to the weight of the flask 5. All of this series of operations can be easily performed with one hand. Subsequently, the holding ring 9 is fitted into the fitting portion 11, thereby completing the setting operation. Since the upper end of the flask 5 is reliably supported by the retaining ring 9 when the set is completed, the flask 5 does not fall over and can be used in shaking culture vessels of strong to weak shaking types.

[Effects of the Invention] As explained above, according to the flask support device of this invention, the flask can be easily set with one hand, thereby improving work efficiency. In addition, since the upper end of the flask can be securely held by the retaining ring, it is not limited by the conditions of use and can be used in a wide range of environments, from those with strong shaking to those with weak shaking.
