Description

  The present invention relates to a transporter capable of smoothly transporting heavy objects such as goods and materials to a target place on a flat surface with extremely little effort and improving the efficiency of a target work. .

  2. Description of the Related Art Conventionally, there are machines called air pallets or air casters for transporting heavy objects such as goods and materials within a predetermined area. This forms an air layer between the airframe on which a heavy object can be placed and the ground, and moves while sliding on the ground. The following Patent Document 1 is listed as a general and representative example of this type. As a basic structure of the air pallet, air is injected into the skirt under the base, and air leaks between the skirt and the floor surface, whereby an air film (air film) is formed. As a result, the airframe is in a state of floating from the ground, and the friction between the airframe and the ground is reduced, and the heavy object can be moved with a small force.

  By the way, transportation of heavy objects is also frequently performed at construction sites. Such heavy objects are construction equipment, generators, building materials, parts, etc. for construction, which are almost made of metal and extremely heavy. In addition, there are building materials made of synthetic resin or the like, but if these are many (quantity), they become very heavy. At the construction site, these heavy objects are transported to a predetermined height by a crane or the like, and the heavy objects are further used from the position where the heavy objects are temporarily placed by the crane at the same place. Up to the target position, it was left up to the labor of the workers or carried by human power such as a wheelbarrow.

  In particular, in a building, the ground and the floor may be constructed on a flat surface on a roof, a rooftop, or a partially completed room. For example, a roof constructed by a sheet-like material or a roof constructed by laying a waterproof sheet has a flat surface, and a wheelbarrow or a pallet with casters can be used at the construction completion point. . However, these wheelbarrows and pallets with casters may cause damage such as the weight of the loaded heavy loads being concentrated on the wheels and casters, and damaging the finished flat surface.

JP-A-4-164708

  Therefore, it is conceivable to use the above-described air pallet or air caster at the construction site. However, conventional hovercraft are premised on use in factories and the like, and are not assumed to be used outdoors. Therefore, there are the following problems when used outdoors, especially on the roof.

  In general, an air caster or an air pallet is used in a wide place on a site such as a factory and a place with a special flat floor provided with a special coating. In other words, a flat floor that is airtight between the airframe and the floor is required. The air caster or air pallet requires a large and heavy power source such as a large compressor or a motor for operating the compressor. However, it is difficult to bring such large machines at the construction site, and because of their weight, beams and purlins may bend without being able to bear the load. I could not.

  Next, depending on the construction site, since the construction period extends from several days to several months, moisture such as rain and dew adheres to the sheet material used for roof construction. When air is sent to the air caster or the air pallet, the entire skirt portion swells and starts to float, but it does not come into uniform contact with the floor surface, and its adhesion varies. When the floor surface is dry, a uniform air layer can be formed between the aircraft and the floor, but when the floor surface is wet or when water drops etc. are attached to the skirt, Moisture (water droplets, etc.) between the surfaces generates a portion where the adhesion is strong and a portion which is not strong, and the discharged air cannot be kept in a uniform state.

  As described above, when the difference in strength between the part that is in close contact and the part that is not in close contact becomes large, a uniform air layer cannot be formed as a whole, and the compressed air escapes from the wrinkled part, so the skirt itself Although it swells, it can no longer exhibit a stable levitation force to lift the aircraft.

  And the air discharged from the skirt part is partially closed with a water film, while on the other hand, an imbalance occurs in which a lot of air is discharged from the wrinkled part of the skirt, not only the air layer is not formed entirely, but also adsorption ( The phenomenon of stacking) occurs. In this case, although the device can be used somehow by lifting it up and moving it to a place where there is no moisture, the same phenomenon occurs when going to a place where there is a water droplet.

  In addition, the water droplets on the skirt will be splashed by the discharge of air, or the splash will be raised, but new water drops will come near the skirt, so the discharge of water drops will eliminate the above-mentioned adsorption (stack) It will not be. In other words, the water droplet forms a water film between the skirt portion and the floor surface, and therefore becomes a resistance and becomes heavy as a brake is applied to prevent the formation of a uniform air layer necessary for the movement of the apparatus. Even if the water is simply removed, the water itself wraps around, so this resistance is not reduced. As described above, various problems arise.

  An object of the present invention is to convey a long construction board formed by a molding machine at a construction site such as a roof near an unformed part of a roof with an extremely small force, and easily and quickly. It is another object of the present invention to provide a transporter that can be transported in a state where the folded roof plate can be easily constructed at the construction position, and can be extremely simplified in structure.

As a result, the above problems were solved. According to a fifth aspect of the present invention, in the transport machine according to any one of the first, second, third, and fourth aspects, the thickness of the second skirt portion is smaller than the thickness of the first skirt portion. The above-mentioned problem has been solved by using a transfer machine.

  According to a sixth aspect of the present invention, in the transfer machine according to any one of the first, second, third, fourth, and fifth aspects, the motor unit is provided as a power source for driving the blower mechanism unit. The power supply unit solves the above problems by using a transporter installed on the base.

  According to a seventh aspect of the present invention, in the transfer machine according to any one of the first, second, third, fourth, and fifth aspects, the motor unit is provided as a power source for driving the blower mechanism unit. The power supply unit is installed outside the base and is connected to the motor unit by an electric cable to solve the above problem. The invention according to claim 8 is the transfer machine according to any one of claims 1, 2, 3, 4 or 5, wherein the engine is used as a power source for driving the blower mechanism. Thus, the above-mentioned problem has been solved. The invention according to claim 9 is the transfer machine according to any one of claims 1, 2, 3, 4, 5, 6, 7 or 8, wherein the base has a transfer machine having casters attached thereto. As a result, the above problems were solved.

  The invention according to claim 10 is the transfer machine according to any one of claims 1, 2, 3, 4, 5, 6, 7, 8, or 9, wherein the blower mechanism is provided above the base. In addition, the above-described problem has been solved by providing a transport device having a configuration in which a gap exists between the air blowing mechanism and the base. The invention of claim 11 is the transfer machine according to claim 10, wherein the base is provided with a handle, and the blower mechanism portion is attached to the handle, thereby solving the above-mentioned problem. . The invention according to claim 12 is the transfer machine according to any one of claims 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11, wherein a width is provided above the base. The above-described problems have been solved by providing a transport machine in which reinforcing members made of a mold material along the longitudinal direction of the base are provided on both sides in the direction.

  According to a thirteenth aspect of the present invention, in the transport machine according to the twelfth aspect, both the reinforcing members are formed with locked portions at predetermined intervals along the longitudinal direction, and the reinforcing members of both the reinforcing members are formed. The above-described problem has been solved by providing a partitioning machine that has a locking part that is detachably locked to the locking part and that has a partition member that has an upright partition plate on the base. The invention according to claim 14 is the transfer machine according to claim 13, wherein the carrier has a locking edge that is detachably locked to the locked portion on the front end side of the base, and is attached to the base. The above-described problem has been solved by providing a transporting machine including a guide member having an inclined guide portion extending forward and downward from the front end of the base.

  According to the first aspect of the present invention, a second skirt portion provided in a ring shape and in a bag shape along the lower surface side of the first skirt portion is provided, and the first skirt portion is provided at a central portion of the first skirt portion. A plurality of air blowing holes for blowing air are formed in the formed gap, and a communication hole is provided between the first skirt part and the second skirt, and the communication hole is provided through the communication hole. Air is sent from the first skirt portion to the second skirt portion.

  Therefore, the second skirt portion sufficiently swells to further apply tension to the swelled first skirt portion. Conventionally, a large amount of air leaks from the wrinkled part of the skirt, and it may be difficult to form a uniform air layer necessary for levitation from the bottom of the skirt. However, in the present invention, this tension makes the first skirt portion less likely to be wrinkled in a sufficiently swollen state, and the air blown from the air blowing holes into the gap inside the first skirt portion is the first skirt portion. However, when the tension is applied by the second skirt portion, a stable air layer for rising can be formed without generating large wrinkles, and smooth movement can be achieved.

  The presence of the second skirt portion makes it difficult for wrinkles to occur in the first skirt portion, and a uniform air layer is formed from below the second skirt portion under any conditions and has a floor surface that is surface-finished. Even if it is a rough surface with some unevenness, not only indoors such as factories and warehouses but also outdoor construction sites, etc., the transfer device can be lifted and moved. The second skirt portion also serves as a cushion for the base 1 and the first skirt portion, and can prevent the loaded heavy object from being impacted. In the first aspect of the present invention, the air jet outlet in the first skirt portion is provided with an opening / closing lid that is opened when air is blown, and the opening / closing lid has a deaeration hole. Thus, deformation of the first skirt portion due to air pressure can be prevented.

  According to a second aspect of the present invention, the first skirt portion includes a skirt sheet material made of synthetic resin, and the periphery of the skirt sheet material is circumferentially attached to the lower surface of the base. The first skirt has a very simple structure, is easy to manufacture, and can be repaired on-site quickly. Can be. In the invention of claim 3, the first skirt portion includes a disc-shaped skirt substrate and a synthetic resin skirt sheet material, and the periphery of the skirt sheet material is adhered along the outer periphery of the skirt substrate. A transfer machine in which the center portion of the skirt sheet material is fixed to the center portion in the radial direction of the skirt substrate with a disk-shaped fixing plate and a fixing tool, and the skirt substrate is fixed to the lower surface of the base. As a result, the first skirt portion can be made strong and durable.

  According to a fourth aspect of the present invention, the second skirt portion is a transporter made of a material having a softness higher than that of the first skirt portion, so that the second skirt portion is uniformly tensioned on all surfaces by air. Therefore, it is possible to easily apply tension to the first skirt portion. In the invention of claim 5, the second skirt portion has an effect equivalent to that of claim 4 because the thickness of the second skirt portion is made thinner than the thickness of the first skirt portion.

  In the sixth aspect of the present invention, the construction transportation machine of the present invention can be self-propelled by having a motor section as a power source for driving the blower mechanism section and the power supply section of the motor section being installed on the transportation base. . In the seventh aspect of the present invention, a motor unit is provided as a power source for driving the blower mechanism unit, and the power source unit of the motor unit is installed outside the transfer base and is connected to the motor unit by an electric cable. As a result, the loading space of the transfer base becomes wider, and more construction materials can be placed.

  In the invention of claim 8, since the engine is used as a power source for driving the blower mechanism portion, the power source portion becomes unnecessary, and the load capacity can be increased. In the invention of claim 9, since the caster is attached to the base, the blower mechanism part becomes defective and can be stopped or moved by the caster when a power failure occurs. In a tenth aspect of the present invention, the air blowing mechanism is provided above the base, and a gap exists between the air blowing mechanism and the base. Only the gap portion can be increased, and the load capacity can be increased.

  In the invention of claim 11, the handle is provided on the base, and the blower mechanism portion is mounted on the handle, so that an operator can operate the blower mechanism portion with the handle. The operability of the transporter can be further improved. In the invention of claim 12, the rigidity of the entire transport machine is improved with a simple structure by providing reinforcing members made of a mold material along the longitudinal direction of the base on both sides in the width direction above the base. Stable conveyance is possible for heavy loads loaded on the base.

  According to a thirteenth aspect of the present invention, both the reinforcing members are formed with locked portions at predetermined intervals along the longitudinal direction, and are detachably locked to the locked portions of both the reinforcing members. A partition member having a latching portion and a partition plate portion that is in an upright state on the base is provided, so that there are very few loads such as materials loaded on the base with respect to the loading area. In addition, the load can be stably loaded by the partition member. In particular, when the load is cylindrical or a sheet material is used as a roll, the load can be maintained on the base without rolling them on the base by the partition member. In a fourteenth aspect of the present invention, there is a locking end edge that is detachably locked to the locked portion on the front end side of the base, and is mounted on the base from the front end of the base forward and downward. Since the guide member having the inclined guide portion extending is provided, when the load is transported to a predetermined position by the transport device of the present invention and the load is lowered from the base, the transport device and the load are impacted.

  Hereinafter, the present invention will be described with reference to the drawings. The transport device of the present invention loads and transports heavy objects while floating on a flat ground surface, road surface or floor surface, and particularly on a construction site, a flat surface such as a flat roof or floor. Suitable for construction. As shown in FIGS. 1 and 2, the transporter according to the present invention includes a base 1, a blower mechanism portion 2, a power supply portion 3, a first skirt portion 4, and a second skirt portion 5. And the ventilation mechanism part 2 is provided in the upper side of the base 1, and the 1st skirt part 4 and the 2nd skirt part 5 are provided in the downward side of the base 1. FIG.

  The base 1 has an elongated or flat plate shape elongated in the longitudinal direction (see FIGS. 1, 6A, 6B, etc.). Further, the specific shape of the base 1 is an elongated shape and the both ends in the longitudinal direction are formed in a semicircular shape. Both sides orthogonal to the longitudinal direction are linear and parallel, and have a substantially “O” shape. Further, the base 1 may be substantially elliptical. You may form in the elongate rectangular shape which made the longitudinal direction long. The base 1 is a part provided on the upper side with devices such as the air blowing mechanism unit 2 and the power source unit 3 and a loading space for loaded heavy objects. Therefore, it is preferable that it is lightweight while having sufficient strength and rigidity to withstand the weight of the load, and is made of wood, synthetic resin, metal, or the like. Here, the upper side of the base 1 refers to a space portion above the upper surface of the base 1. Therefore, the air blowing mechanism unit 2 is installed so as to be directly placed on the upper surface side of the base 1 or is installed at a predetermined height position in the upper part of the base 1 via a handle 11 or the like described later. Sometimes. In the case where the blower mechanism 2 is installed at a predetermined height position in the upper part of the base 1, the blower mechanism 2 does not directly contact the base 1, and there is a gap between the blower mechanism 2 and the base 1. Will exist.

  The blower mechanism 2 serves to send air into the first skirt 4 (see FIGS. 1B and 2C). The blower mechanism unit 2 has substantially the same structure as a general air blower, and includes a blower unit 21 and a power source 22 for driving the blower unit 21. The blower 21 is often a generally general blower. The air blower 21 has substantially the same structure as a general air blower, and has an impeller mounted therein.

  A motor unit 22a and an engine 22b exist as a power source 22 for driving the blower unit 21. In the embodiment in which the motor unit 22a is used, a power supply unit 3 that supplies electricity to the motor unit 22a is provided. In the blower mechanism part 2, the blower part 21 and the motor part 22a often have an integrated body. A power supply unit 3 for driving the blower mechanism unit 2 and its motor unit 22a is installed above the base 1 [see FIG. 1B]. That is, the power supply unit 3 may be directly installed on the upper surface of the base 1 or may be disposed at a predetermined height position above the base 1.

  The power supply unit 3 is often a generally general small generator. The power supply unit 3 is configured to be detachable from the air blowing mechanism unit 2 of the base 1 so that the power supply unit 3 can be replaced. By installing the power supply unit 3 on the base 1, it is possible to perform a maneuvering operation with a single carrier, and it is easy to handle. The power supply unit 3 may be a rechargeable small pack type battery, and this type is mounted to the air blowing mechanism unit 2 in a replaceable manner. Therefore, this type of pack-type power supply unit 3 is attached to the blower mechanism unit 2 installed on the upper side of the base 1 and installed at a predetermined height position on the upper side of the base 1. Become. Since the pack-type power supply unit 3 is small in size, an operator can keep the transporter used for a long time by exchanging the power supply unit 3 by always carrying a plurality. Can do.

  The power supply unit 3 is not installed on the base 1 but is installed at a predetermined position on the work site, and is connected to the motor unit 22a of the blower mechanism unit 2 by the power cable 31 so that the blower mechanism unit 2 is driven. [See FIG. 5A]. The type in which the power supply unit 3 is not installed on the base 1 has an advantage that the weight of the transporter itself can be reduced and the load amount of the construction material 9 to be transported can be increased.

  An engine 22b such as gasoline or diesel may be used as the power source 22 for driving the blower mechanism unit 2 (see FIG. 5B). When the engine 22b is used, the output shaft of the engine 22b is directly connected to the blower mechanism 2 as it is to blow air. Therefore, when the engine 22b is used, the power supply unit 3 is not necessary.

  The blower unit 21 of the blower mechanism unit 2 communicates with the first skirt portion 4 mounted on the lower surface side of the base 1 by an air supply pipe 23 that penetrates the base 1. And the air produced | generated by the ventilation mechanism part 2 is supplied to the 1st skirt part 4 and the 2nd skirt part 5, respectively. The first skirt portion 4 is an annular air reservoir structure on the lower surface side of the base 1. The first skirt portion 4 includes two first linear skirt components 4a and 4a arranged in parallel or substantially parallel along the longitudinal direction of the base 1, and both the first linear skirt components. It consists of two first semicircular skirt constituent parts 4b and 4b located at both longitudinal ends of the parts 4a and 4a.

The two first semicircular skirt components 4b and 4b are symmetrical on both sides in the longitudinal direction. Both first linear skirt constituent parts 4a, 4a and both first semicircular skirt constituent parts 4b, 4b are integrally continuous, and are formed as a substantially "0" -shaped substantially floating ring shape. [
1A, 6A, and 6B]. Alternatively, the first skirt portion 4 may have a substantially elliptical shape.

  A band plate-like fixing plate 45 is disposed at the center position of the annular portion of the first skirt portion 4, and is fixed to the lower surface side of the base 1 via a fixing tool such as a bolt. The fixed plate 45 is a plate material having an elongated flat band shape, and the length in the longitudinal direction is substantially equal to the length of the first linear skirt component 4a. As described above, the first skirt portion 4 is configured to have an air chamber in which air accumulates as an endless tubular air reservoir structure having a substantially donut shape or a substantially floating ring shape as described above. [See FIG. 1, FIG. 2, FIG. 3 (A) to FIG. 3 (C)].

The first skirt portion 4 is made of synthetic resin and is provided with a skirt sheet material 4s having a substantially “O” shape. The periphery of the skirt sheet material 4s is circumferentially attached to the lower surface of the base 1, and the central portion of the skirt sheet material 4s is formed by a disk-shaped fixing plate 45 and a fixing tool 46 such as a bolt / nut. 1 is fixed to the lower surface side (FIGS. 1 and 2).

More specifically, the skirt sheet material 4 s is a skirt substrate 4 having a substantially “O” shape.
4, the periphery of the skirt sheet material 4 s is adhered along the outer periphery of the skirt substrate 44, and the center portion of the skirt sheet material 4 s is formed in a disk shape at the radial center position of the skirt substrate 44. The fixing plate 45 and the fixing tool 46 are used for fixing.

  In the first skirt portion 4, air supplied from the blower mechanism portion 2 through the air supply pipe 23 is stored, and when the air is sufficiently filled, the skirt portion 4 becomes a circular shape or a substantially elliptical shape from a deflated state. It transforms into a floating ring shape. A plurality of air blowing holes 41 are formed in the first skirt portion 4 (see FIGS. 1 to 3). The air blowing hole 41 is formed on the inner peripheral wall surface side where the gap S of the first skirt portion 4 is formed. Then, the air blown out from the air blowing hole 41 is accumulated in the gap S surrounded by the first skirt portion 4, and the carrier is lifted by the air.

  The second skirt portion 5 is provided on the lower surface side of the first skirt portion 4. The second skirt portion 5 is formed in a circular shape (or elliptical shape) that is substantially similar to the first skirt portion 4 along the circumferential direction of the first skirt portion 4 (see FIG. 1). Here, the similarity means that the center line in the circumferential direction of the second skirt portion 5 substantially coincides with the center line in the circumferential direction of the first skirt portion 4.

Therefore, if the first skirt portion 4 is substantially “O” -shaped, the second skirt portion 5 is
It has a substantially “O” shape similar to the skirt portion 4. The second skirt portion 5 is formed with a smaller volume for air to enter than the first skirt portion 4. The second skirt portion 5 also includes second linear skirt constituent portions 5a and 5a and second semicircular skirt constituent portions 5b and 5b as in the first skirt portion 4. Both the second linear skirt constituent parts 5a, 5a and the two second semicircular skirt constituent parts 5b, 5b are integrally continuous. It is formed in the shape of a floating ring [FIGS. 1 (A), 6 (A), (B)
reference〕.

Specifically, the second skirt portion 5 is provided with a second skirt sheet material 5s having a substantially “O” shape, and an outer peripheral edge and an inner peripheral edge thereof are adhered to the first skirt portion 4 (see FIG. 1, FIG. 2). A portion between the outer peripheral edge and the inner peripheral edge of the sheet material becomes a space filled with air. As a means for attaching the second skirt sheet material 5 s constituting the second skirt portion 5, seam welding, an adhesive, or the like is used, but any means is preferably attached extremely firmly. A portion where the second skirt sheet material 5s of the second skirt portion 5 is attached to the first skirt portion 4 by the attaching means is shown in the drawing as an attachment portion 5t. The illustrated sticking part 5t is welded (FIGS. 1 and 2).

  A communication hole 42 is formed between the first skirt part 4 and the second skirt part 5 (see FIG. 1B, FIG. 2, FIG. 3A to FIG. 3C). The air sent into the first skirt portion 4 by the blower portion 21 of the blower mechanism portion 2 sufficiently inflates the first skirt portion 4, and further, the air passes through the communication hole 42 and enters the second skirt portion 5. It is sent. The communication hole 42 has a small diameter, and the air in the second skirt portion 5 does not flow backward to the first skirt portion 4 side while the transporter is operating.

The second skirt portion 5 has a substantially “O” shape in which the cross section orthogonal to the circumferential direction is substantially semicircular in a state where the inside is sufficiently filled with air. During the operation of the transporter, the second skirt portion 5 that is sufficiently inflated by air is always positioned below the first skirt portion 4, and the second skirt portion 5 is grounded more than the first skirt portion 4. It is close to (road surface, floor surface).

  The second skirt portion 5 has a smaller volume filled with air than the first skirt portion 4, and is easily subjected to tension on the surface of the second skirt portion 5 and is less likely to wrinkle. The sufficiently expanded second skirt portion 5 gives tension to the entire first skirt portion 4 by its own tension. Therefore, the surface of the first skirt portion 4 can be made in a state in which wrinkles are unlikely to occur.

  Since the first skirt portion 4 is less likely to wrinkle, the air pressure in the gap S of the first skirt portion 4 is always stable, and is uniform between the second skirt portion 5 and the ground at any location. An air layer serving as a pressure can be formed (see FIG. 3A). Thereby, even if the ground surface is a flat surface with some unevenness, the transfer device can float well and can move well.

  Moreover, since the 2nd skirt part 5 is provided in the lower surface side of the 1st skirt part 4, it also serves as a cushion material of the whole conveyance machine [refer FIG. 4 (B)]. Furthermore, as described above, the second skirt portion 5 makes it difficult for the first skirt portion 4 to be wrinkled, so that even if rainwater or the like accumulates on the ground, a large amount of air can be generated from the gap portion S from some locations. Since there is no leakage, stable levitation is possible even in a place where rainwater has accumulated (see FIG. 3C).

  The second skirt portion 5 is preferably made of a material that is softer than the first skirt portion 4. Here, the high softness of the material means that the material is softer. That is, the second skirt part 5 is more flexible than the first skirt part 4.

  The second skirt portion 5 is preferably more elastic than the first skirt portion 4. Further, the thickness of the material of the second skirt portion 5 may be made thinner than the thickness of the material of the first skirt portion 4. In this case, the first skirt portion 4 and the second skirt portion 5 may be made of the same material.

  That is, by reducing the thickness of the material, the material is more flexible than the thicker one. By giving the second skirt part 5 a lot of flexibility and elasticity, when the second skirt part 5 is sufficiently swollen by air, the tension is also large, and as a result, no wrinkles are generated. Or even if wrinkles occur, they are slight.

  An open / close lid 6 is provided at the air outlet 23a on the first skirt 4 side of the air supply pipe 23 (see FIG. 4). The opening / closing lid 6 opens when air is ejected from the air ejection port 23a. The opening / closing lid 6 has a deaeration hole 61 (see FIG. 4A). The opening / closing lid 6 is preferably made of a material having elasticity, and is specifically a rubber member. The opening / closing lid 6 is always elastically biased so as to close the air outlet 23a. The deaeration hole 61 is a small-diameter through hole, and one or a plurality of the deaeration holes 61 are formed.

  The air flowing in the rectified state through the air supply pipe 23 is ejected outward at a stretch at the air ejection port 23a. At this time, a frictional resistance is generated in the air flow around the air outlet 23a, and a part of the ejected air becomes a vortex and flows in a direction opposite to the air ejection direction, that is, turbulence. Flow may occur.

  Due to this vortex, a part of the first skirt part 4 is sucked, and as a result, a part thereof is easily depressed. Therefore, the outflow of air increases from the recessed portion of the first skirt portion 4, and the outflow decreases from the other portions, resulting in an unbalanced air discharge state on the lower surface side of the first skirt portion 4. As a result, a phenomenon in which the entire skirt is adsorbed on the floor surface occurs, and a good floating state cannot be achieved. In conventional air pallets and air casters, such a situation is likely to occur.

  The opening / closing lid 6 prevents such a phenomenon. The open / close lid 6 changes the ejection direction when air is ejected in the air supply into the first skirt portion 4, and changes the flow direction without making the flow direction constant at all times, thereby preventing the generation of air eddy currents. It is a thing. That is, since the opening / closing lid 6 vibrates in a swinging state by the jetted air, the direction of the air supplied to the first skirt portion 4 is randomly changed (see FIG. 4B). As a result, air vortex flow hardly occurs at the air outlet 23a, and at the same time, air is smoothly supplied to the entire inside of the first skirt portion 4.

  The opening / closing lid 6 also operates as a check valve for air flow with respect to the air outlet 23a. That is, when air is supplied from the air outlet 23a into the first skirt portion 4, it is opened by the wind pressure of the air, and is closed when the air tries to flow backward from the first skirt portion 4 toward the air outlet 23a. Therefore, the deaeration hole 61 serves to draw out air from the swollen first skirt portion 4 and the second skirt portion 5 and squeeze them when the transporter of the present invention stops operating. [See FIG. 4C].

  A handle 11 may be attached to the base 1. The handle 11 is moved by a worker's hand, or the handles 11 of a plurality of transport bodies A, A,... Are connected to move the transport bodies A, A,. You can also The handle 11 may be detachable from the base 1. The handle 11 is attached to a portion near the end side of the base 1, and the worker pushes the handle 11 by hand. Therefore, in the longitudinal direction of the base 1, the side on which the handle 11 is mounted is the rear side of the transporter, and the opposite side of the rear side in the longitudinal direction is the front side of the transporter [see FIG. 1 (B)]. . However, the front-rear direction of the transfer machine is appropriately determined by the operator to use, and the handle 11 mounting side of the base 1 may be the front side and the opposite side may be the rear side. The handle 11 has a gate shape or an inverted U shape (see FIGS. 6 and 10A and 10C).

  Moreover, the handle | steering-wheel 11 may be made into the folding type which made the handle | base handle | base part 11a the rotation center [refer FIG. 13 (A), (B)]. As described above, when the blower mechanism unit 2 installed on the upper side of the base 1 is installed at a predetermined height position from the upper surface of the base 1, the blower mechanism unit 2 is mounted at an arbitrary position of the handle 11. Will be. Specifically, the handle 11 may be provided with a reinforcing plate at an intermediate position in the height direction, and the blower mechanism 2 is attached to the reinforcing plate via a member such as a fixture ( (See FIG. 13). In addition, although not particularly illustrated, the handle 11 may be a bicycle handle type that is divided into two branches above a single column. Therefore, the end side of the base to which the handle 11 is attached is the rear side of the transporter, and the end opposite to the rear side end is the front side of the transporter (see FIG. 1B). However, the front-rear direction of the transfer machine is appropriately determined by the worker to be used, and the end side of the base 1 on the handle 11 mounting side may be the front side, and the opposite end side may be the rear side. .

  There is an embodiment in which a plurality of conveyors according to the present invention can be used in combination (see FIG. 6B). In this embodiment, two conveyors are arranged at a predetermined interval and connected by a shaft-like beam member 71. As the beam material 71, a steel pipe or the like is used. Specifically, a single pipe constituting a scaffold used at a construction site is used as it is.

  The two conveyors have two beam members 71 arranged in parallel, and both ends of each beam member 71 are attached to the upper surfaces of the bases 1 and 1 of the respective conveyor units by using mounting brackets 72 such as clamps. Connected and fixed. The two beam members 71, 71 connecting the two transport machines serve as a cargo bed as they are. Specifically, a pillow material 73 having a rectangular parallelepiped shape is disposed so as to straddle the two beam members 71, 71, and a building material such as a deck plate is installed on the pillow material. In addition, it is a premise that the power supply part 3 which supplies electricity to the ventilation mechanism part 2 is each provided in the connected 2 units | sets of conveying machines. In addition, in the case where only the blower mechanism unit 2 is installed in the two conveyors and the power supply unit 3 is not provided, the power supply unit 3 that supplies electricity to these units is provided in addition to the two connected conveyors. Additional transporters may be added. In this case, three conveyors may be connected [see FIG. 6B].

  In this embodiment, a plurality of transport machines connected by a plurality of beam members 71, 71,... Have the handle 11 attached only to a transport machine that is moved by an operator directly by hand. It is also possible to remove the handle 11 so that a wider space can be secured for each. Furthermore, there is an embodiment in which the caster 12 is provided in the transport machine of the present invention (see FIG. 9). The casters 12 are mounted at four corners on the lower surface side of the base 1. The caster 12 serves as a stabilizer (stabilizer) when the transporter is moved. It is also effective for preventing movement obstacles and sticking caused by water droplets. Moreover, since the fixed height is maintained, the pallet brake phenomenon due to water is less likely to occur.

  Next, operation | movement of the conveying machine of this invention is demonstrated. First, the blower mechanism unit 2 is started, and air is supplied from the blower unit 21 via the air supply pipe 23 to the first skirt portion 4 at the bottom of the base 1. Air is supplied to the first skirt portion 4, and air is also supplied to the second skirt portion 5 through the communication hole 42 of the first skirt portion 4. Thereby, air is sufficiently supplied to the first skirt portion 4 and the second skirt portion 5.

  With sufficient swelling of the first skirt portion 4, air is blown out from the plurality of air blowing holes 41 formed in the first skirt portion 4 into the gap portion S formed by the first skirt portion 4, and in the gap portion S. The ejected air bounces off the ground and collides with the air ejected from the other air blowing holes 41 and blows upward. The blown-up air collides with the lower surface of the base material 4 and generates lift. The air in the gap portion S passes between the lower surface of the second skirt portion 5 and the ground and flows out to the outside.

  At this time, an air layer (air film) is formed between the second skirt portion 5 and the ground, and the apparatus floats. In this state, there is no contact between the ground (floor surface) and the apparatus, so that the frictional resistance becomes an extremely small value. The apparatus can be moved with a small force and can carry heavy objects.

  Conventional air pallets and air casters require a smooth surface (eg flooring floor, concrete paved floor, etc.). According to this apparatus, the unevenness of the wrinkle portion generated in the first skirt portion 4 due to the cushioning property by the flexible second skirt portion 5 attached under the first skirt portion 4 can be complemented. Air film forming troubles due to water droplets can be avoided.

  In addition, since conventional air pallets and air casters have high adhesion to the ground and the floor, if the skirt is made of only vinyl, noise is generated due to vibration in air discharge. However, in the present invention, the first skirt portion 4 is made of rubber and the second skirt portion 5 is made of thin vinyl, so that vibration can be absorbed and generation of noise can be suppressed. In addition, because of the cushioning property of the second skirt portion 5, the ground is rough, and even on an asphalt surface that cannot be moved by a normal hovercraft, the adhesiveness is high and air film formation is performed, so that it can be used.

  Next, a usage example of the transporter of the present invention will be described. It is suitable for the construction of roofs, rooftops, floors, etc. having a waterproof structure, depending on the sheet material at the construction site. As shown in FIGS. 7 and 8, the sheet construction method is such that a heat insulating material 92 is laid on a metal deck plate 91, and a resin sheet material 93 such as a polymer material is adhered thereon, and then roof, roof Alternatively, a sheet-like enclosure such as a floor is constructed.

  In the construction process, various materials are lifted to the construction site in advance for each process and attached. First, the deck plate 91 is constructed [see FIGS. 7A and 8A]. A heat insulating material 92 is laid on the deck plate 91. The heat insulating material 92 has a flat plate shape, and is laid manually by an operator up to an area where the transfer machine of the present invention can operate. When the heat insulating material 92 has spread over the entire deck plate 91, a flat ground surface (road surface) is completed, and the transporter of the present invention can move while floating.

  The heat insulating plate 92 is loaded on the transporter, moved within a range where the transporter can move, and the stacked heat insulating material 92 is laid. In this way, laying is performed while transporting the heat insulating material 92 to a predetermined position by the transporter, and a floor surface with a large number of heat insulating materials 92 is constructed. When the floor surface by the heat insulating material 92 is completed, the conveyor can be moved over the entire surface. In this state, the sheet material 93 wound in a roll shape is stacked on the conveyance machine, conveyed to a predetermined position, and the sheet material 93 is laid on the floor surface by the heat insulating material 92 (see FIG. 8). Thereby, the flat surface of a building can be constructed.

  There is also an embodiment in which a reinforcing member 81 is mounted above the base 1 of the transporter (see FIGS. 10 and 11). In this embodiment, when a heavy building material is placed on a base that is long in the longitudinal direction, the base 1 is prevented from bending so as to be bent by its weight, and stable running can be performed. It is what you want to do.

  For the reinforcing member 81, a die steel material having a substantially inverted hat shape in cross section is used. Specifically, a bowl-shaped part 81a having a concave cross section is formed, and horizontal horizontal pieces 81b, 81b are formed from the upper end portion in the width direction of the bowl-shaped part 81a (see FIGS. 10 and 11). The reinforcing members 81 are arranged so that the two are located on both sides in the width direction of the base 1 so that the longitudinal direction thereof is along the longitudinal direction of the base 1. Then, the bottom surface of the bowl-shaped portion 81a is installed on the base 1 and fixed to the base 1 with a fixing tool such as a screw (see FIGS. 10 and 11). The two reinforcing members 81 preferably have large cross-sectional secondary moments in terms of strength. The handle 11 is installed on the horizontal pieces 81b and 81b of the reinforcing members 81 and 81, respectively. Specifically, the handle base 11a of the handle 11 is installed and fixed on the horizontal piece 81b.

  Next, there is an embodiment in which the reinforcing member 81 is configured such that the partition member 82 and the guide member 83 are mounted (see FIGS. 10 and 11). In this embodiment, first, the locking portions 81c and 81c are formed on the horizontal pieces 81b and 81b of the reinforcing members 81 and 81 mounted on both sides in the width direction of the base 1 so as to face each other. A plurality of locked portions 81c, 81c,... Are formed on the horizontal piece 81b of each reinforcing member 81. The intervals between the plurality of locked portions 81c, 81c,... Are equal or substantially equal in the longitudinal direction of the horizontal piece 81b. Specifically, the locked portion 81c is a linear notch, and the line direction of the notch is orthogonal to the longitudinal direction of the horizontal piece 81b. The inner end side of the locked portion 81c formed on the horizontal piece 81b is opened outward.

  The partition member 82 has a locking portion 82 a that is detachably locked to the locked portions 81 c and 81 c of both the reinforcing members 81 and has a partition plate portion 82 b that stands upright on the base 1. A bent seat portion 82c is formed between the locking portion 82a and the partition plate portion 82b. The bent seat portion 82c is a folded portion that is substantially horizontal with respect to the locking portion 82a and the partition plate portion 82b. Then, both sides in the width direction of the locking portion 3 of the partition member 82 are locked so as to be inserted into opposed locked portions 81c and 81c formed on the horizontal pieces 81b and 81b of the reinforcing members 81 and 81. The bent seat 82c is placed on the horizontal pieces 81b and 81b, and the partition member 82 can be installed on the reinforcing member 81 in a stable state.

  And the partition member 82 can be installed in arbitrary positions along the longitudinal direction on the base 1, and the loading space can be divided at arbitrary positions in the longitudinal direction of the base 1 (see FIG. 12A). Thereby, there are few loads on the base 1, and it can prevent that the cylindrical construction material 9 grade | etc., Rolls carelessly on the base 1, and falls off from the base 1. FIG. The guide member 83 has a locking end edge 83a that is detachably locked to the locked portion 81c on the front end side of the base 1, and is forwardly moved from the front end of the base 1 in a state of being attached to the base 1. It has the inclination guide part 83b extended in the side and below. Then, with the guide member 83 properly attached to the reinforcing member 81 of the base 1, the inclined guide portion 83b becomes a gently inclined guide plate, and the construction material 9 such as a cylindrical shape can be safely removed from the base 1 without impact. It can be taken down (see FIG. 12B).

  As described above, the transporter according to the present invention has been described as being used for transporting heavy objects at a building site. However, the transporter can be used in many other fields, for example, leisure such as vacation, and simple vehicles. It can also be used as a means for carrying a simple baggage.
