Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the retention of odors in small articles, and consists in using a special endless double tube to prevent damage to the articles while also making it easier to take them in and out. .

The specially structured endless double cylinder constituting the holder of the present invention is a double cylinder made of a flexible material, and the double cylinders are continuous at both ends to form an endless structure. ing.

Below, the above endless double cylinder will be explained with reference to the drawings.
1A is a longitudinal sectional view, FIG. 1B is a transverse sectional view, and FIG. 1C is a perspective view.

10 is an endless double cylinder, 12 is its outer cylinder, and 14 is its inner cylinder.

The outer cylinder 12 and the inner cylinder 14 have the same diameter and are made of the same material. Also, the outer cylinder 12 and the inner cylinder 14
is continuous at both ends, creating an endless structure throughout. This endless single-layer tube is made of flexible and airtight materials such as rubber and soft synthetic resin. Further, if turbolin, which is a thin fiber cloth coated with rubber or the like on one or both sides, is used, it will be highly durable. Also, the second
As shown in Figures a and b, the outer surface of an endless double tube 10 made of rubber or the like may be covered with a thin fiber cloth 16. In this case, the fiber cloth 16 and rubber etc. do not necessarily need to be bonded. 18 is a valve through which fluid can be introduced into the endless heavy cylinder 10.

The valve 18 can be freely selected from any known structure, but under normal conditions, the endless double cylinder 1
It is required that the structure does not protrude to the outer surface of the 0. Also, although it is acceptable to protrude inward to some extent, it is preferable that the height is as low as possible. When the height of the valve 18 is 1/4 of the diameter of the endless double cylinder 10, when it is located on the outer cylinder 12, the inner cylinder 14
This is not preferable because there is a risk that the endless double cylinder 10 may not be turned over smoothly. If the diameter of the valve 18 is too large, the endless double cylinder 10
valve 18 because it inhibits reversal when it is located at the end of
The diameter of the endless double cylinder 10 should be 1/2 or less of the diameter of the endless double cylinder 10. Some examples of valves that satisfy the above conditions are illustrated below.

First, the one shown in FIG. 3 is one example, and 20 is the cylinder wall of the endless double cylinder 10, in which a hole 22 is bored.

24 is a soft plastic base whose base 26 is fixed around the front pore 22, and a tube 28, which is slightly harder than the base 24, is fixed at its tip.

30 is a lid.

When introducing fluid, the valve 18 is pulled out as shown in FIG. 3a, the lid 30 is removed, and the fluid is introduced from the open end of the tube 28. Once the desired amount of fluid has been delivered, the lid 30 is inserted into the opening of the tube 28 and sealed. Next, when the lid 30 is pressed against the cylindrical wall 20', the soft plastic base 24 is turned over and inserted into the hole 2, as shown in FIG. 3b.
2 into the endless double tube 10, the tube 28 and the lid 30 are also buried in the hole 22 together with the base 24, and the outer surface of the endless double tube 10 becomes smooth. According to the diagram, lid 3
The flange portion 32 at the tip of the cylindrical tube 20 continues to protrude outward from the cylindrical wall 20, but this degree of protrusion has virtually no effect.

FIG. 4 shows another example of the valve 18, in which the inward protrusion of the endless double cylinder 10 is minimized.

341 is a bolt, 36 is a nut, and the threaded part of the bolt 34 is inserted into the hole 22 of the cylinder wall 20, and the nut 3 is inserted from the inside.
6, the hole 22 is sealed. A screw hole 38 is bored in the center of the bolt 34, into which a machine screw 40 is screwed. The machine screw 40 is removed and fluid is introduced through the screw hole 38, and then the machine screw 40 is screwed into the screw hole 38 to seal the screw hole 38. In this example, the thickness of the entire valve 18 can be reduced by reducing the thickness of the head 42 of the bolt 34 and the nut 36 as much as possible as shown in the figure. Further, by using a dish-shaped washer 44 whose central portion is concave inward, it is possible to prevent the head 42 of the bolt 34 from protruding from the surface of the cylinder wall 20. FIG. 5 shows yet another example, which is a simpler valve.

This is a highly elastic rubber chip 4 on the inner surface of the cylinder wall 20.
6 is glued together. Since the tip 46 has high elasticity, even if a hole is pierced by a needle or the like, when the needle is pulled out, the hole will be closed due to the elasticity of the tip 46, and the internal pressure will not leak out. Therefore, a hollow needle like a hypodermic needle is pierced from the outside of the endless double cylinder 10, and fluid is introduced through the hollow needle. When the hollow needle is pulled out after the feeding is completed, the rubber elasticity of the tip 46 closes the needle hole.
The structure of the valve 18 is not limited to these, and any known valve that satisfies the above-mentioned conditions may be selected as appropriate.

The endless double tube 10 receives fluid from these valves 18 .

Then, the space between the outer cylinder 12 and the inner cylinder 14 is pressurized by the pressure of the fluid, and as a result, the outer cylinder 12 is expanded by the internal pressure, and the inner cylinder 14 is crushed by the external pressure. Air is usually sufficient as the pressure fluid, but other suitable gases, liquids, powders or granules, or mixtures thereof can be used depending on the application. In addition, the pressure of the fluid should be set appropriately depending on the use of each endless double cylinder 10, and depending on the use, it may be necessary to apply a pressure of several k9/m, and in other uses. In some cases, it may be necessary not to pressurize the underside.

By the way, the outer cylinder 12 in this endless double cylinder 101
The inner cylinder 14 and the inner cylinder 14 are not fixed, but can be replaced with each other.

This endless double cylinder 10 has an outer cylinder 12 and an inner cylinder 1.
No. 4 has the same material and diameter, and is uniform throughout. Therefore, under certain conditions, only one half of the tube constitutes the outer tube 12 and the other half constitutes the inner tube 14. Therefore, if an external force is applied to this endless double cylinder 101, the outer cylinder 12 and the inner cylinder 14 can be reversed and replaced, and the part that was the outer cylinder 12 can also become the inner cylinder 14, and vice versa. The part that was the inner cylinder 14 is now the outer cylinder 12.
It is also possible to become For example, in FIG. 1, if a force is applied upward to the outer cylinder 12 and downward to the inner cylinder 14, the outer cylinder 12 and the inner cylinder 14 will be moved by these forces. However, since the outer cylinder 12 and the inner cylinder 14 are continuous at both ends, at the upper end, the inner cylinder 14 pulls in the upper end of the outer cylinder 12 and makes it a part of the inner cylinder 14, and at the lower end, the outer cylinder 14 12 pulls out the lower end of the inner cylinder 14 to the outer cylinder 12.
It will become part of the Therefore, if these additions are continued, the endless double cylinder 10 will repeatedly reverse itself and move like an endless track. In this endless double tube 10', the force that prevents the reversal movement is the frictional resistance between the outer tube 12 and the inner tube 14, and the fact that the outer tube 12 is gradually crushed at both ends of the endless double tube 10 and the inner tube 14, and when the inner cylinder 14 is gradually expanded to become the outer cylinder 12, only one force of resistance is applied due to the elasticity of the material. The latter is extremely rare because the material is flexible. In addition, in the former case, the outer cylinder is swollen round and the inner cylinder is crushed small, so there is almost no contact between them, and the resistance due to this is extremely low. Therefore, the force required for the reversal movement is extremely small, and the reversal can be easily performed with a small amount of force. In addition, endless double tube 10
If the length is quite long, the frictional resistance due to contact between the outer cylinder 12 and the inner cylinder 14 cannot be ignored, so it is better to seal in a small amount of lubricant. Glycerin, soap water, or a mixture thereof is suitable as the lubricant, and it is sufficient to encapsulate the lubricant in an amount sufficient to uniformly adhere to the inner surface of the endless double cylinder. It is also possible to use a lubricating oil that does not affect the material of the endless double tube. Next, the above-mentioned endless double cylinder has unique properties as described below.

First, as described above, the outer cylinder and the inner cylinder can be easily reversed and replaced with a small amount of force.

The force for this reversal can be generated not only from the outside but also from within. That is, by enclosing a large amount of liquid, powder, granules, or a mixture thereof in this endless double cylinder 10, it is possible to cause the cylinder to naturally reverse itself due to its own weight. In the case shown in FIG. 6, a space 48 in the endless double cylinder 10 is filled with liquid 50 in an amount approximately half of the space, and air is filled in the remaining space. If the outer cylinder 12 is supported from the outside in this endless double cylinder, a downward force is applied to the outer cylinder 12 and the inner cylinder 14 due to the weight of the liquid. However, since the outer cylinder 12 is supported from the outside, it cannot descend, but the inner cylinder 14 is not supported at all from the outside and is in a free state, so only the inner cylinder 14 can move due to the weight of the liquid 50. descend. Therefore, at the upper end, the outer cylinder 12 is inverted and becomes the inner cylinder 14, and at the lower end, the inner cylinder 14 is inverted and becomes the outer cylinder 12. Therefore, the endless double cylinder 10 naturally descends while being reversed. In this case, the entire endless double clause is a single unit. Instead of moving down, only the inner cylinder 14 descends, and the outer cylinder 12 remains stationary.

By simply inverting the endless double cylinder, the outer cylinder 12 and the inner cylinder 14 are exchanged, and the endless double cylinder 10 as a whole moves to a lower position. Moreover, if a shaft, a string, etc. are inserted into the inner cylinder 14 of the endless double cylinder 10 to support the inner cylinder 14, the outer cylinder 12 will descend, contrary to the above, and similarly the endless double cylinder 10 will be lowered. Descend while turning.

In these cases, the endless double cylinder 10 descends without any friction with the device supporting it, which is completely different from the general case where an object slides down on the surface of a support. The liquid 50 sealed in the endless double cylinder 10 is preferably a lubricating liquid such as glycerin or soap water.

Although the amount varies depending on the diameter, length, material, etc. of the endless double tube 10, it is preferably about 10 to 90% of the volume of the space 48 inside the endless double tube 10. Also, powder or granules with a large specific gravity can be used instead of liquid,
In this case, the amount can be reduced compared to when a liquid is used. The powdery or granular material used here is preferably one with a high specific gravity such as glass, steel, lead, litharge, or the like. It is preferable that these objects are spherical in shape, and that they are hard and deformable. Furthermore, if the surface is coated with a material having a small friction coefficient such as polytetrafluoroethylene, the effect will be even greater. Alternatively, a mixture of powder or granules and liquid may be used. The third property of the endless double cylinder is that it can apply external or internal pressure to other objects.

For example, as shown in FIG. 7, the inner cylinder 14 of the endless double cylinder 10
When the shaft 52 is inserted into the endless double tube 1
The pressure of the fluid sealed in the inner cylinder 1 increases as shown by arrow P.
4, the shaft 52 is pressed, and external pressure is applied to the shaft 52. Also, endless double tube 10
As mentioned above, since the shaft performs an infinite reversal motion, it is possible to freely change the tightening position while tightening the shaft, and the force required for this is small. Moreover, the endless double cylinder 10 evenly tightens the shaft 52 with its inner cylinder 14, and the frictional resistance between them is large, so the shaft 52 can be pulled out by sliding inside the inner cylinder 14 without reversing the endless double cylinder 10, or It is almost impossible to move it. Also, if the endless double tube 10 is inserted into the tube 54 as shown in FIG.
2 to apply internal pressure to the tube 54 from the inside in the direction of arrow P.

In this case, the endless double tube 10 is turned over while the tube 64
The fact that it is possible to move inside the shaft, and that it is impossible to move or fall off without turning over is the same as in the case of applying external pressure to the shaft. Moreover, since the endless single tube 10 is made of a flexible material,
Even if the inner diameter of the tube 54 changes somewhat, the endless double cylinder 10 deforms to match the inner diameter of the tube 54 and can move. Furthermore, in order to apply pressure to an object as described above, it is of course necessary that the space 48 inside the endless double cylinder 10 is pressurized, but it is not necessarily in a pressurized state beforehand. It doesn't require that.

This is because, for example, in FIG.
When the shaft 52 is inserted, the volume of the space 48 of the endless double cylinder 10 is reduced by an amount corresponding to the volume of the shaft 52, and the space 48 is naturally pressurized. Also, when inserting the endless double tube 10 into the tube 54 as shown in FIG. 8, the inner diameter of the tube 54 is 4 mm smaller than the diameter of the endless double tube 10, so that the endless double tube 10 is deformed. If so, it will be naturally pressurized in the same way. Furthermore, in general, when applying internal or external pressure to an object, a step for applying pressure is required.

For example, in order to apply internal pressure to a pipe, etc., it is necessary to seal the pipe and introduce pressure fluid into it.In order to apply external pressure to an object, it is necessary to place it inside a pressurized can. Pressure fluid must be introduced into the However, when applying external pressure or internal pressure using the endless double cylinder 10 of the present invention, such a pressurizing step is not necessary, and the inside of the inner cylinder 14 is simply turned over while the endless double cylinder 10 is turned over. Insert the shaft 52 into the tube 5 or insert the endless double tube 10 into the tube 5.
You only need to insert it into 4. As described above, the endless double tube that constitutes the holder of the present invention has distinctive properties not found in conventionally known basic structures, and this property can be used to prevent damage as follows. This makes it convenient to safely hold small items that are easy to handle.

For example, when holding small precision instruments or articles that are easily damaged, these articles 230 are inserted into the inner tube 14 of the endless double tube 10 as shown in FIG. Then, the inner tube 14, which is crushed by the external pressure applied by the fluid sealed in the space 48, firmly tightens the inserted article 230, so that the article 230' inserted into the inner tube 14 is pushed outward from the endless double tube. It is securely held without slipping out. Moreover, as mentioned above, since the endless double cylinder has a buffering effect, the article will not be damaged by external impact. Moreover, when putting the article 230 into the endless double tube lo, the article 230 is pushed into the inner tube 14 from one end of the endless single tube 10, and the endless double tube 10 is slightly reversed so that the article is located in the center. That's enough. Also, when taking out an article, by pushing one end of the inner tube 14 of the endless double tube 10 and turning it slightly, the article can be taken out from the other end. Further, as shown in FIG. 10, if a thin end 232 of the endless double tube 1 is inserted in advance, the endless double tube 10 can be easily reversed and the article 230 can be easily put in and taken out. Moreover, what is shown in FIG. 11 is an example in which the endless double tube is used as an article holder in an article conveyor such as a conveyor. Then, the string 234 is passed around rollers 236 and 238 provided at the front and rear of the endless double tube 10, and both ends are connected to form an endless shape.

Furthermore, this narrow 234 is compressed between the rollers 236 and 238 by the compression roller 2401, and thus the endless double cylinder 10
It is pressed against the outer cylinder 12 of. Here, roller 2
When either or both of roller 36 and roller 238 are driven to rotate clockwise, narrow 234 also rotates accordingly. Then, the inner cylinder 14 of the endless double cylinder 10 becomes thin 2
34 and moves to the left, and the outer cylinder 12 is pulled by the string 234 pressed against it and moves to the right. Therefore, while the endless double cylinder 10 is continuously reversed in the direction of the arrow, its position does not move and is held at a constant position. If the small item 230 is pressed from the right end of the endless double cylinder 10,
With the reversal of the cylinder wall of the endless double cylinder 10, the inner cylinder 14
Inward, it is tightly wrapped and held in the inner cylinder 14, and is sequentially sent to the left. Then, at the left end of the endless double tube 10, the inner tube 14 is turned over, and the article 23 that was wrapped and held therein is released and falls into the receiver 242. Therefore, according to the present invention, the article 230 can be conveyed smoothly not only horizontally but also vertically, diagonally, or along a curved path in an article conveying device such as a conveyor. It can also be effectively used as a holder.
