Abstract

PROBLEM TO BE SOLVED: To provide a hose type cargo presser which prevents the vibration and collapse of cargo in running of the cargo and which does not interfer with the loading and unloading of the cargo and enables smooth and quick work. SOLUTION: Introducing compressed air into a hose 1 through an opening and closing valve 14 and a pipe 4 from a sub tank 12 will expand the hose 1, which catch cargo between the right and left sidewalls 6 and 7 of the ban body 5. Consequently, the vibration and collapse are prevented. When compressed air is discharged from inside the hose 1, the hose 1 is clashed in flat form by the spring force of an elastic hose retainer 2. Therefore, the interference between the hose 1 and the cargo is prevented, and the work of loading and unloading is performed smoothly and quickly.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has at least a side wall such as a van body of a truck, and is applied to hold a load by the side wall to prevent vibration and the like. Hose-type load holding device. 2. Description of the Related Art FIG. 7 shows a schematic structure of a hose type load holding device which has been generally used in the past. A hose 1a is provided between the load 16 and the side wall 6a of the van body, and compressed air is supplied from the sub tank 12a into the hose 1a via an opening / closing valve 14a. Further, the hose 1a is held in a horizontal state by a suspension rope 21 suspended from the beam portion 20 as illustrated. Compressed air is supplied into the hose 1a in order to prevent vibration of the load 16 during traveling, the hose 1a is bulged, and the outer periphery of the hose 1a is extended to the load 16 and the side wall 6.
Hold the load by pressing it against a. On the other hand, when unloading the load, compressed air is discharged from the hose 1a to release the pressure contact between the hose 1a and the load 16. On the other hand, as an example of a known technique relating to the load holding device, there is one disclosed in Japanese Utility Model Laid-Open No. 6-27321. This "cargo collapse prevention airbag curtain" is equipped with an air mat on the inner surface of the wing and the tilt part of the truck bed having wings and a tilt part and in the center of the bed, and supplies compressed air from the vehicle air source to the air mat. It prevents the collapse of the cargo. Both the prior art and the known art shown in FIG. 7 are effective for preventing the vibration of the load and the collapse of the load, but have the following problems. doing. First, in the case of the former prior art, since the hose 1a is suspended and supported by the suspension rope 21, the hose 1a easily moves in the front-rear and left-right directions in the free state. Therefore, there is a problem that the positioning of the hose 1a becomes unstable and the loading and unloading work of the load cannot be performed smoothly. Also, even if compressed air is discharged from the hose 1a, the hose 1a itself does not have much elasticity, so when the air pressure inside the hose 1a becomes equal to the atmospheric pressure outside, the air inside the hose 1a is discharged outside the hose 1a. Instead, the shape of the hose 1a is maintained as it is. Therefore, there is a problem that the hose 1a interferes with the load, which hinders the loading and unloading work. On the other hand, in the latter known technique, since the air mat is held at a predetermined position, there is no problem due to the movement of the air mat, but the air mat is in a semi-bulging state even when the compressed air is discharged as in the above-mentioned conventional technique. However, there is a problem in that the load and the air mat interfere with each other when loading or unloading, which hinders these operations. In the case of the latter known technique, it is possible to almost completely shrink the air mat by switching the switching valve during engine operation to suck the air in the air mat to the air cleaner side.
The above cannot be done when the engine is stopped. The present invention solves the above problems and prevents the hose from wobbling during loading and unloading work, and the hose is crushed when compressed air is discharged to eliminate interference with the load. An object of the present invention is to provide a hose-type load holding device capable of smoothly and quickly performing loading and unloading work. In order to achieve the above object, the present invention is provided between a side surface of a load and a wall surface of a stationary side to hold the load and to load and load the load. A load restraining device that does not interfere with the load when being lowered, a hollow pipe-shaped hose that has a closed space and can be expanded and contracted, and an elastic hose holder that abuts the outer circumference of the hose and is stretched and supported on the wall surface. A hose-type load holding device is provided which is provided with a pipe that connects the compressed air supply source and the hose and that has an on-off valve interposed therebetween. More specifically, the elastic hose holder is a plurality of elastic hose holders arranged at appropriate intervals along the longitudinal direction of the hose, and the elastic hose holder is
A tongue member that comes into contact with the outer periphery of the hose, and a spring member that is stretched between both ends of the tongue member and the wall surface. When compressed air is not supplied to the spring member, at least the tongue member is interposed. Having a spring force capable of pressing the hose into a flat shape, the elastic hose holder is
A rubber cord that is in contact with the outer circumference of the hose and is fixed at both ends to the wall surface, and the rubber cord is elastically capable of pressing at least the hose flatly when compressed air is not supplied to the wall surface. It is characterized by being stretched. When loading is completed, the on-off valve is opened and compressed air is introduced into the hose from the compressed air supply source. The hose expands by compressed air and presses against the load and the wall surface to prevent the load from moving. Since the elastic hose holder is abutted and stretched around the outer circumference of the hose, the elastic hose holder is pressed against the outer circumference of the hose by the expansion of the hose and holds the hose. As described above, the vibration of the cargo and the collapse of the cargo are prevented. When unloading, the compressed air in the hose is discharged. Since the elastic hose holder is stretched and pressed against the hose as described above, when the compressed air in the hose is exhausted, it functions to press the outer periphery of the hose and crush the hose into a flat shape. As described above, the hose is crushed so as not to interfere with the load, and the load can be easily unloaded and loaded. When the present invention is used for a van body of a vehicle, a compressed air supply source for the vehicle can be used, so that no special air source is required. Further, the hose is held at a predetermined position by the elastic hose holder even in a free state in which compressed air is not supplied, so that the wobble does not occur. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which the embodiment is applied to a van body of a vehicle. The hose-type load holding device of this embodiment is roughly classified into a hose 1, an elastic hose holder 2 for holding the hose 1, a compressed air supply source 3 for supplying compressed air into the hose 1, and the hose 1 and the hose 1. The pipe 4 and the like for connecting In this embodiment, the hose 1 is composed of a pair of right and left, and is a hollow pipe having a closed space and having an expandable / reducible diameter. For example, a resin or rubber hose is used. The hose 1 is provided adjacent to the left and right side walls 6 and 7 of the van body 5 and extends along the front-rear direction. In addition,
The hose 1 has such a size and shape that it can be pressed against the side surface of the load (not shown) when it is expanded. As the elastic hose holder 2, a spring type hose holder 2a is used in this embodiment. As shown in FIG. 1, a plurality of spring type hose holders 2a (hereinafter referred to as holders 2a) are arranged at appropriate intervals along the longitudinal direction of the hose 1. 2A and 2B show the detailed structure and mounting structure. The holder 2a includes a tongue member 8 that is arranged in contact with a part of the outer circumference of the hose 1 and is sewn on it, and spring members 9 and 9 that connect one ends to both ends thereof. The other end of the spring member 9 is engaged with and held by a locking tool 10 fixed to the side wall 6 and the side wall 7. As shown in FIG. 2A, when the hose 1 is in a bulged state, the spring members 9, 9
Is pulled so that the tongue member 8 is pulled toward the side wall 6 (7) and the inner surface of the tongue member 8 presses the outer surface of the hose 1. The holders 2a are arranged at intervals of about 30 to 40 [cm], and the spring force of the spring member 9 is capable of crushing the hose 1 into a substantially flat shape when compressed air is not present in the hose 1. Further, since the tongue member 8 directly contacts the outer circumference of the hose 1 and the cargo, it is desirable that the tongue member 8 is formed of a material that does not damage them and is not damaged by them, such as cloth or resin. In this embodiment, the compressed air supply source 3 comprises a sub tank 12 connected to the vehicle air supply source 11. The sub tank 12 has a pressure control valve 13 for preventing excessive air from being supplied to the hose 1 side. Attached. In this embodiment, the pipes 4 are pipes 4a and 4b connected to the left hose 1 and the right hose 1, respectively.
The pipe 4c is connected to these components, the pipe 4d is connected to the sub-tank 12 side via the opening / closing valve 14, the pipe 4e is connected to the exhaust side via the opening / closing valve 15, and the like. In addition, the sub-tank 12 has a pipe 4f communicating with the vehicle air supply source 11.
Are linked. Next, the operation of this embodiment will be described.
3A and 3B schematically show FIGS. 2A and 2B. When compressed air is supplied into the hose 1 as shown in FIG. 3 (a) and the hose 1 bulges in a round shape as shown in the drawing, the spring members 9 and 9 expand to increase the tension thereof, and the tongue member 8 causes the hose 1 to expand. The hose 1 is held by the tongue member 8 while being pressed against the outer periphery of the hose 1. On the other hand, when the compressed air is discharged from the hose 1 and the compressed air in the hose 1 disappears, the tongue member 8 acts so as to crush the hose 1 by the spring force of the spring members 9 and 9 to compress. By forcing the hose 1 to be crushed, almost all the air remaining in the hose 1 is discharged, and the hose 1 is deformed into a flat shape as shown in FIG. 3B. In this state, the pressing force of the tongue member 8 by the spring member 9 may be released, but it is preferable that a slight pressing force is applied. FIGS. 4 and 5 show the state of engagement between the holder 2a and the load 16 of this embodiment. As shown in FIG. 4, when compressed air is introduced into the hose 1, the hose 1 swells as described above, and the tongue member 8 pressed against the outer circumference of the hose 1, more specifically, the outer circumference of the hose 1, is loaded. Press 16. Since the load 16 is pressed by the holders 2a from both side surfaces, it is held immovably in the substantial center of the van body 5. Therefore, the movement of the load 16 and the collapse of the load do not occur during traveling. FIG. 5 shows the unloading and loading of the load 16. When the compressed air is discharged from the hose 1, the hose 1 is flattened as shown by the pressing force of the holder 2a as described above. Therefore, a gap 17 is created between the hose 1 and the holder 2a and the load 16. Further, the hose 1 is slightly pressed by the holder 2a toward the side wall 6 and the side wall 7, and is held as it is. Therefore, the load 16 can be smoothly and quickly unloaded without being hindered by the hose 1 or the like. Also, reloading is easy. FIG. 6 shows an elastic hose holder according to another embodiment of the present invention. In this embodiment, rubber type hose holder 2b
(Hereinafter, referred to as a holder 2b) is adopted. The holder 2b is made of a rubber string 18, and both ends of the holder 2b are attached to the locking members 19 of the side wall 6 or the side wall 7. In this state, the rubber cord 18 is stretched between the locking members 19 and 19 and pressed against the outer circumference of the hose 1. When compressed air is supplied into the hose 1 as in the above embodiment, the hose 1 swells as shown in FIG. 6A, and the rubber cord 18 is further stretched to press the outer circumference of the hose 1. When the compressed air is discharged from the hose 1, the rubber cord 1
The hose 1 is pressed by the tension of 8 and deforms into a flat shape as shown in FIG. 6 (b). From the above, the same effect as that of the above embodiment can be obtained. In the above description, the elastic hose holder 2 is used.
Although the holders 2a and 2b have been described as above, the elastic hose holder 2 in the present invention is not limited to these. That is, the hose 1 may be pressed against the outer circumference of the hose 1 and elastically deformed to crush the hose 1 into a substantially flat shape even after the compressed air is completely discharged from the hose 1. Further, in the above description, one hose 1 is arranged on each of the left and right sides, but a large number may be used. According to the present invention, the following remarkable effects are exhibited. 1) The load is held by supplying compressed air to a hose capable of expanding and contracting and expanding the hose. Therefore, vibration and load collapse do not occur during traveling. Further, since the hose is held by the elastic hose holder which is stretched and supported, it is held at a predetermined position by the elastic hose holder in the bulged state or the free state. Therefore, there is no wobbling and the like, which does not hinder the loading and unloading of cargo. 2) When compressed air is discharged from the inside of the hose, the hose is forcibly crushed by the pressing force of the elastic hose holder that is in pressure contact with the outer circumference of the hose, and the residual air is pushed out to form a flat shape. Therefore, a gap is created between the cargo and the cargo, which does not interfere with the unloading of the cargo. 3) From the above, loading and unloading work of a load can be carried out smoothly and quickly, and loading work efficiency can be improved. 4) Since the elastic hose holder can be easily attached and detached, it is possible to arbitrarily set an appropriate size, shape and number according to the place of attachment.
