Abstract

PURPOSE:To relieve a driver of discomfort in driving with shock suddenly applied from the rear lessened and to improve durability of a rubber bag main body for transportation of fluid by making a partition plate for restraining of movement of the fluid incorporated in the rubber bag main body and fixed to a position where the rubber bag main body swells out by movement of the fluid at the time when braking is applied to a vehicle. CONSTITUTION:A partition plate 5 is installed to a position where a rubber bag main body 3 swells out as a fluid Q housed therein moves at the time when braking or the like is applied to a vehicle carrying the bag, or, in other words, to a position 1/4l that is in the position about one-fourth, as viewed from the front side of the vehicle, of the overall length (l) of the rubber bag main body. The upper end 5a and the lower end 5b of the partition plate 5 are fixed with adhesive agent or the like respectively to the upper and the lower positions of the internal surface of the rubber bag main body 3. The partition plate 5 is constructed so that it is set being aslant at a specified angle alpha (according to experiments or the like, the angle alpha is desirable to be 45 degrees) when the fluid Q is in a standstill position, and becomes roughly upright in conformity with swelling deformation of the rubber bag main body 3 at the time of movement of the fluid Q, and thereby acts on restraining of the movement of the fluid Q. It is desirable that bonding of the partition plate 5 is made so that durability is secured in the direction along which the fluid Q moves when the braking is applied to the vehicle 1.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rubber bag for transporting fluids filled with fluids such as liquids and fluids, and more particularly, the present invention relates to rubber bags for transporting fluids filled with fluids such as liquids and fluids. The present invention relates to a rubber bag for transporting fluid that effectively prevents fluid from moving to a portion where a rubber-lined body bulges.

(Prior art) Conventionally, when transporting liquids, fluids, etc., special vehicles have been used, but these dedicated vehicles can only be used for one-way outbound or return journeys to transport the object; It is common for a one-way trip to return empty, and since the vehicle is exclusively used for transporting liquids, it is not possible to load and transport other cargo, which poses a problem.

Therefore, in recent years, in order to transport not only liquids, fluids, etc., but also ordinary cargo, transport rubber bags that can be filled with liquids, fluids, etc. are used to be loaded into containers or shipping boxes. It has been proposed to do so.

Note that when transporting ordinary cargo that does not transport liquids, fluids, etc., most of the other cargo can be effectively utilized by folding and storing the rubber bag for transportation. By using it in this way, it is possible to transport both liquids and regular cargo.

[Problem that the invention seeks to solve]

However, when transporting rubber bags filled with liquid or the like in containers or shipping boxes, the following problems occur.

That is, as shown in FIG.
When transporting a rubber transport bag 3 filled with the following items in a container 4, when the vehicle 1 is running normally (running at a constant speed without acceleration or deceleration), the dot-dash line in Figure 1 As shown, the movement of the liquid W is small, and the deformation of the transportation rubber bag 3 is also small. However, when the vehicle 1 is braking, starting, or accelerating, the inertia of the vehicle 1 causes the liquid W to
moves in the front-rear direction of the vehicle 1 to remove the transportation rubber bag 3 3a,
Make it bulge locally as shown in 3b.

In particular, when the vehicle l is braking, the deceleration is generally greater than when it is accelerating, so the corresponding movement of the liquid W increases, which increases the degree of bulge in the transportation rubber bag 3. Additionally, there was a problem in that the driver experienced a so-called whiplash-like phenomenon in which the driver felt as if he was being pushed up from behind, which worsened his sense of control. In addition, since the liquid W moves repeatedly in the longitudinal direction of the vehicle 1, the transportation rubber bag 3
There was also the problem that the corresponding deformation would be repeated, resulting in a decrease in durability.

[Purpose of the invention]

This invention was devised by focusing on such conventional problems, and suppresses the movement of liquid especially when braking the vehicle, thereby reducing the poor steering feeling without giving the driver a sudden thrusting feeling. The object of the present invention is to provide a rubber bag for transporting fluids, which has a rubber-wrapped main body for transport and has improved durability.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a partition plate for suppressing the movement of fluids inside the rubber packaging body and at a portion where the rubber packaging body bulges due to the movement of fluids when the vehicle is braked. The gist of this is that

[Operation of the Invention] The present invention is configured as described above, and includes a portion of the rubber-clad body in which a fluid moves and the rubber-clad body bulges when the vehicle is braked;
That is, a partition plate for suppressing the movement of the fluid is provided at a position approximately 174 points from the front side of the vehicle over the entire length of the rubber-clad body, and when the fluid is stationary, this partition plate is tilted at a predetermined angle to prevent the fluid from moving. When moving, the rubber-wrapped body expands and deforms to become almost vertical, suppressing the movement of the fluid, which reduces the driver's poor driving sensation and improves the durability of the rubber-wrapped body. It is possible.

[Embodiments of the invention]

The present invention will be described in detail below based on the accompanying drawings.

Note that the same components as those in the conventional example are given the same reference numerals, and the description thereof will be omitted.

FIG. 2 is an explanatory view showing the operating state of the partition vi5 during deformation of the rubber-wrapped main body 3 according to the present invention, and FIG. 3 is an enlarged side view taken along the arrows ■-■ in FIG. 3 is
Like conventional products, it is composed of a rubber-like elastic body with a reinforcing layer embedded in it, and is liquid.

It is provided with an inlet/outlet (not shown) for injecting and discharging a fluid Q such as a fluid.

The partition plate 5 is located at a position where the rubber-clad body 3 bulges due to movement of the fluid Q when the vehicle 1 is braked, that is, at a position approximately l/41 from the front side of the vehicle where the rubber-clad body has a total length l. The upper and lower ends 5a and 5b of this temporary partition 5 are fixed to the upper and lower inner wall surfaces of the rubber-covered main body 3 via an adhesive or the like, and when the fluid Q is stationary, a predetermined angle α (experimental α from etc.
: 45° is preferred), and when the fluid Q is moved, it is configured to be in a substantially vertical state as the rubber-fitted main body 3 bulges and deforms, thereby suppressing the movement of the fluid Q.

In addition, as for the direction in which the partition plate 5 is adhered, it is preferable that the partition plate 5 is arranged so as to have durability in the direction in which the fluid Q moves during braking of the vehicle 1 (from the rear side of the vehicle 1 to the front). In addition, since liquid resistance is required as a material, a fiber-reinforced plastic or rubber material that is rigid and slightly elongated is preferable. Furthermore, the number of partitions [5] is not limited to one, and a plurality of partitions may be used.

Furthermore, as shown in FIG. 3, the partition Fi5 is formed into a substantially rectangular shape with a plurality of (two in this embodiment) flow holes 6 in the center, so that the fluid can flow through the partition Fi5. Q
When disposed in a rubber-wrapped main body 3 having an elliptical cross-sectional shape, the fluid Q flows in the front-rear direction of the partition plate 5 through the flow holes 6, and the space portions 7 on both sides
The fluid Q flows in the front-rear direction of the partition plate 5 via a and 7b.

The height h of the partition plate 5 disposed inside the rubber-wrapped body 3 is the height h of the rubber-wrapped body 3 in a stationary state with the fluid Q enclosed.
A good value is about 1.6 times of o, which is suitable for suppressing the fluid Q by at least 20
Assuming that X is carried out, it has been found that a height of about 1.6 times the height ho of the rubber-covered main body 3 in a stationary state is good.

This invention provides the partition plate 5 for suppressing the movement of the fluid Q at a position approximately 1/41 from the front side of the vehicle l having the full length l of the rubber-clad body as described above, so that when the vehicle l is braked. When the fluid Q moves, the rubber wrapping main body 3 bulges and deforms and becomes approximately vertical, suppressing the movement of the fluid Q. This reduces the driver's poor driving sensation and improves the durability of the rubber wrapping main body. It is possible to improve your sexuality.

〔Effect of the invention〕

In this invention, as described above, a partition plate for suppressing the movement of the fluid is installed inside the rubber body and at a portion where the rubber body bulges due to the movement of the fluid when the vehicle is braked. In particular, by suppressing the movement of liquid when braking the vehicle, the driver does not feel a sudden upward thrust, reducing the poor steering sensation, and also improving the durability of the rubber-covered body for transportation. There is.
