Description

  The present invention relates to a load collapse prevention tool for preventing a load collapse of a load loaded on a pallet or a carriage.

Conventionally, various means have been employed to prevent the collapse of a load loaded on a pallet or a carriage, and one of them is to wrap the loaded load in the circumferential direction using a stretch film. However, this method of using a stretch film has the advantage of being able to adapt to the size of the loaded baggage, but it requires the operator to wrap the film around the loaded baggage many times. Since the winding operation itself is troublesome and the film cannot be used repeatedly, if the used film is burned as it is, the environment is adversely affected by the generation of CO ₂ . In addition, there are adhesive tapes or buckles provided at both ends in the winding direction of the sheet to tighten them, but although it can be used repeatedly, it is necessary for the operator to wind the film around the load. The point is the same as that of a stretch film, and the film winding operation is troublesome.

  Further, Patent Document 1 discloses a pallet locking tool (load collapse prevention tool) having a rectangular lid shape for preventing load collapse of a load loaded on a pallet. Is a structure that assembles four fixed-shaped peripheral walls and one upper wall, so the shape of the load that can be handled (vertical and horizontal dimensions) is uniquely determined, and the same pallet locking device makes the vertical and horizontal There is a drawback that it cannot be set for different loads with different dimensions.

  Patent Document 2 discloses a load collapse prevention device in which four independent sheets are connected by a plurality of belts, but the four individual sheets are connected by a plurality of belts. However, the arrangement position can be selected independently. Therefore, to set the load on the pallet, the operator goes around the load and temporarily fixes each sheet to the load and after all the sheets are temporarily fixed Each belt is pulled to set each sheet on the loaded luggage to prevent the loaded luggage from collapsing. Therefore, it is necessary for the operator to set the load collapse prevention tool around the loaded luggage, and this point has not been improved.

  In the present invention, the work piece does not go around the load on the pallet or the carriage, and the load is kept in a predetermined position with the load being covered to prevent the collapse of the load. An object of the present invention is to provide a load collapse prevention device that can be bound and easily folded into a rectangular plate shape when not in use.

  The invention of claim 1 for solving the above-mentioned problem is a load collapse prevention device for preventing load collapse of a load loaded on a pallet or a carriage, and is formed integrally with a sheet, and the top surface portion And can be expanded into a rectangular lid with a bottom opening provided with each of the four side portions, and can prevent a slightly large size in plan view with respect to a load of the smallest plane size that can be covered. In order to maintain the overall shape of the prevention device main body by lifting it by one operator by maintaining the shape of the device main body and all four side surface portions of the prevention device main body, or each of the three side surface portions. A shape-retaining member that is integrally attached independently for each part, and is connected to the outside of each side part of the prevention device main body at a plurality of positions so as to be movable in the circumferential direction, and the prevention device body covers the load In the state of being covered, A bundling member that absorbs the extra length in the circumferential direction of the baggage to bring the loaded cargo into a bundled state, and one operator spreads out in a rectangular lid shape at any one of the four sides of the loaded baggage. And covering the loaded body from above with the bundling member so as to absorb the extra length in the circumferential direction of the body of the protective device on the one side to bind the loaded body. It is characterized by that.

  According to the first aspect of the present invention, the entire shape of the prevention tool main body or the three side surfaces are lifted up by one operator so that the overall shape of the rectangular lid with the bottom surface opened or a shape close thereto is obtained. The shape-retaining member is independently attached to each side surface portion so as to retain the shape. For this reason, it is possible for one worker to expand the prevention device main body into a rectangular lid shape on any one of the four sides of the loaded luggage and to cover the loaded luggage from the upper side of the loaded luggage. Become. In addition, when the shape retaining member is attached to only three of the four side surface portions of the preventer main body, the side surface portion to which the shape retaining member is not attached is located at a position facing the operator. Arrange and perform the covering operation. After that, when the loaded baggage is bundled by the bundling member at the one side of the loaded baggage, the extra length in the circumferential direction of the main body of the prevention tool is absorbed, and the loaded baggage is bundled by the bundling member so that the collapse of the load can be prevented. Is done.

  That is, according to the first aspect of the present invention, the worker can stand on any one of the four sides of the loaded cargo loaded on the pallet or the carriage without moving around the loaded cargo at all. By covering the loader loaded on the main body of the protective load held in the shape of a rectangular lid with the loader, and then binding the loader with a binding member on the one side, one worker can Moreover, it is possible to prevent the collapse of the load by setting a load collapse prevention tool on the loaded load while standing at a certain position with respect to the load.

  In addition, when the shape retaining member is attached to only three side surfaces of all the side surface portions, each side surface portion is held in a square shape by the shape retaining member, except for the side surface portion to which the shape retaining member is not attached. It is shaped. Therefore, in a state where the main body of the protective device having an open bottom surface is expanded in a lid shape, two of the four side surface portions are overlapped with each other so that the two side surfaces overlap each other. The top surface part folded in the shape of an equilateral triangle is overlapped on the side surface part that is overlapped as a whole. After that, when the two side-by-side side parts are further overlapped and folded into a four-layered state, the top surface part folded in an isosceles triangle shape is further folded into two, and each upper and lower shape is retained. The whole load collapse prevention tool is folded into a rectangular plate shape by being sandwiched between the members. Thereby, the top surface part of the prevention tool main body which consists only of an indefinite shape sheet | seat is pinched | interposed between each shape-retaining member which is shape-holding a side part, and does not slip out during handling. Therefore, since the load collapse prevention tool used repeatedly can be folded in the square shape corresponded to one side part of the prevention tool main body, the convenience as a load collapse prevention tool is significantly improved.

  Further, the invention of claim 2 is a load collapse prevention device for preventing the load collapse of the load loaded on the pallet or the carriage, and is formed integrally with a sheet, and has only four side portions. A square frame plate that can be spread out, and is slightly similar in size in plan view to a load of the smallest plane size that can be covered; In order to maintain the overall shape of the main body of the preventive device by lifting each of the side surface portions or the three side surface portions, it is possible to maintain the entire shape of the main body of the preventive device independently by one operator. And a shape retaining member attached to the outer side of each side portion of the prevention device main body at a plurality of locations so as to be movable in the circumferential direction, Absorbs the extra length in the circumferential direction of the body A bundling member for bringing the loaded baggage into a bundled state, and the worker body is provided with the prevention tool body expanded in a rectangular frame plate shape at any one of the four sides of the loaded baggage. After the cover is covered from above, an extra length portion in the circumferential direction of the prevention device main body is absorbed by the binding member at the one side portion to bind the load.

  The invention according to claim 2 is substantially the same as the invention according to claim 1, and the operator can prevent the operator from spreading out in a square frame plate shape at any one of the four sides of the load on the pallet or carriage. The main body is arranged so as to be fitted to the outside of the loaded luggage from above the loaded luggage, and when the loaded luggage is bundled by the bundling member in the state as it is, the extra length in the circumferential direction of the preventer main body is absorbed, The loaded luggage is bundled by the bundling member in a state that can prevent the cargo from collapsing. That is, with the worker standing on one side of the loaded luggage, the main body of the protector can be arranged outside the loaded luggage, and the loaded luggage can be bound by the bundling member at the same position to prevent the load from collapsing. Therefore, it is not necessary for the operator to go around the loaded luggage, and a load collapse prevention tool for preventing the collapse of the loaded luggage can be easily set on the loaded luggage by one worker. In addition, when the shape retaining member is attached to only three of the four side surfaces, the side surface to which the shape retaining member is not attached is arranged so as to face the operator and loaded. The arrangement of the main body of the protector with respect to the luggage is the same as that of the first aspect of the invention.

  In addition, in order to fold the load collapse prevention tool expanded in the shape of a rectangular frame plate when not in use, after overlapping two adjacent side surfaces, each side surface formed by overlapping the two sheets is used. When two sheets are further overlapped and the four side surfaces are overlapped with each other, the whole is folded into a thin plate shape. Even when folded or in a folded state after folding, the side surface portion is held in a square shape by the shape-retaining member, so that the folding is facilitated and the folded state can be maintained. Thus, since it can be folded into a thin plate shape in just two steps, the folding operation is easy, and the load collapse prevention tool is not bulky in the folded state, and the handling becomes easy.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the shape-retaining member is a slightly smaller similar shape to the side surface portion of the prevention device main body, and is a square frame made of wire. It is characterized by comprising.

  According to invention of Claim 3, since the side part of a prevention tool main body consists of only a film similarly to a top | upper surface part, it is an indefinite shape, However, The shape-retaining member which shape-holds the said side part consists of a wire. Even a rectangular frame has a shape retaining function equivalent to that of a plate-like member in view of the function of retaining the shape. As a result, when a frame-shaped shape retaining member made of wire is used, the portion surrounded by the frame-shaped shape retaining member remains a sheet that can be freely deformed. As a result, the overall shape retaining member becomes lighter, and the work of covering and folding the load collapse prevention tool with respect to the load is facilitated.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, a shape retaining member is attached to each of the side portions of the main body of the preventer, and a plan view of the four shape retaining members is provided. The adjacent portions of the two shape-retaining members arranged on one diagonal line are connected to each other so as to be rotatable, and the remaining adjacent portions of the two shape-retaining members arranged on the other diagonal line Between the sections, there is provided an extra length part that can be absorbed along the circumferential direction when the loaded luggage is bound according to the vertical and horizontal sizes of the loaded luggage.

  According to the invention of claim 4, since the total four shape retaining members are rotatably connected to each other in two adjacent portions arranged on one diagonal line in plan view, It is excellent in shape retention when it is opened in the shape of an open lid, and it becomes easy for one worker to easily cover the loaded body with the prevention tool body opened in the shape of a square lid. Further, the surplus length portion existing between the two adjacent portions of the two shape-retaining members arranged on the other diagonal line in a plan view allows the same load collapse prevention device to vertically and horizontally within a certain range. It is possible to handle loads of different sizes.

  Further, the invention of claim 5 is the invention of claim 1, wherein a shape retaining member is attached to each side surface portion of the main body of the preventer, and one of the four shape retaining members is on one diagonal line in plan view. The adjacent portions of the two shape-retaining members disposed on the other are connected to each other so as to be rotatable with respect to each other, and between the remaining adjacent portions of the two shape-retaining members disposed on the other diagonal line In accordance with the vertical and horizontal sizes of the loaded luggage, an extra length portion is provided that can be absorbed along the circumferential direction when the loaded luggage is bundled, and is expanded in a rectangular lid shape at the center of the top surface of the preventer body. When the protective device main body is folded, a top surface grip piece is provided for preventing the top surface portion from sinking downward and gripping it with one hand of the operator and lifting it upward. One specific side part of the side parts is grasped with the other hand of the operator and the specific part Side gripping piece for pushing the side surface portion inward is characterized in that provided at the end of the elongated portion side of the shape retaining member.

  According to the invention of claim 5, since the entire top surface portion of the prevention device main body remains a sheet, the top surface portion sinks downward when the prevention device main body expanded in a rectangular lid shape is folded. This is an obstacle to folding. For this reason, according to the invention of claim 5, the operator grasps the top surface grip piece of the top surface portion of the main body of the protection device expanded in the shape of a square lid with one hand of the operator and the specific side surface with the other hand. In a state where the side gripping piece provided at the end of the extra length portion side of the shape retaining member of the part is gripped, the side part provided with the side gripping piece is pushed inward and is rotatably connected. The side surface portions to which the respective shape retaining members are attached are overlapped with each other, and the prevention tool main body is folded.

  According to a sixth aspect of the present invention, in the invention according to any one of the first to fifth aspects, each side surface portion of the prevention device main body is provided with an insertion portion through which the binding member is inserted, and the binding The member is characterized in that a bundling member is inserted into each inserted portion so that the member can be folded together with the prevention tool main body.

  According to the invention of claim 6, the bundling member that binds the loaded luggage over the entire circumference in a state in which the loaded load is covered with the load collapse prevention tool is continuous with each side surface portion of the prevention tool main body. It is provided, and is folded together with the main body of the preventive tool when the load collapse preventive tool is folded. Therefore, there is no risk of losing the binding member, and there is no need to fold up and store the binding member alone.Furthermore, when the load collapse prevention device is expanded in a rectangular lid shape, the binding members are all on the side portions. Since it is attached over the circumference, the work of preventing load collapse is also facilitated.

  According to a seventh aspect of the present invention, in the invention according to any one of the first, third, fourth, fifth, and sixth aspects, the shape retaining member is attached to the side surface portion of the seat body in the vicinity of the lower end edge. The portion of the side surface portion above the shape retaining member is a deformable portion that can be arbitrarily deformed according to the three-dimensional shape of the upper portion of the loaded luggage, and is deformed according to the three-dimensional shape of the upper portion of the loaded luggage. The deformation shape of the top surface portion of the seat body and the deformation portion of each side surface portion is maintained by a deformation shape maintaining member attached between the side surface portion and the top surface portion.

  According to the seventh aspect of the present invention, it is possible to cope with a non-planar loaded luggage having a rectangular shape in plan view and having an irregular upper portion, and is above the shape retaining member on the side surface portion of the seat body. The seat body deformed in accordance with the shape of the upper portion of the loaded luggage by deforming both the deformed portion and the top surface portion of the bag in accordance with the shape of the upper portion of the loaded luggage and attaching a deformed shape maintaining member to the deformed portion. The deformed shape of the upper part of can be maintained.

  According to the present invention, a rectangular lid is formed by a shape retaining member with respect to the loaded luggage without turning around the loaded luggage on the pallet or the carriage while the operator is positioned on any one side of the pallet or the carriage. In the state of covering the main body of the protective device held in the shape of a frame or a rectangular frame plate, the excess length of the main body of the protective device is absorbed, and the load is collapsed by binding the load with the binding member. Can be prevented. In this way, the operator can prevent the load from collapsing without turning around the pallet or cart while remaining on one side of the pallet or cart. One worker can perform the work of covering and bundling.

  In addition, since all of the side surfaces or the three side surfaces of the prevention device main body formed in a rectangular lid shape or a rectangular frame plate shape with an irregularly shaped sheet are held in a square shape by a shape-retaining member. The side part to which the shape-retaining member is attached can hold a square that is a fixed shape. The prevention device main body can hold a square lid shape or a square frame plate shape. Therefore, in order to fold the load collapse prevention device when not in use, after the four side surfaces are folded in half, if it has a top surface, the top surface is made into an isosceles triangle and folded in half. It is easy to fold into a square plate that does not become bulky by superimposing it on the side face part, then folding the side face part that is folded in half, and then putting all four side face parts together. be able to.

  Hereinafter, the present invention will be described in more detail with reference to a plurality of optimum embodiments.

First, the invention of claim 1 will be described with reference to FIGS. FIG. 1 is a perspective view of a state in which the load collapse of the loaded luggage J ₁ is prevented by the load collapse prevention tool P _{1 according} to the invention of claim 1, and FIGS. was spread ₁ square lid-like (were developed) state obliquely upward, and a perspective view from obliquely below, FIG. 3, the structure of the cargo collapse preventing device P ₁ of the seat body S ₁ is been expanded FIG. 4 is a perspective view showing the members separated, and FIG. 4 is a perspective view showing a state where an operator stands on one side of the pallet K and covers the loaded body J ₁ with the sheet body S ₁ expanded in a rectangular lid shape. 5 (a) and 5 (b) are schematic plan views showing that the load collapse of the loaded luggage J ₁ and J ₁ ′ having different plane sizes can be prevented by the same load collapse prevention tool P ₁ . . The load collapse prevention tool P ₁ is formed integrally with a sheet, and includes a top surface portion 1 and four side surface portions 2a and 2b, and has a rectangular lid shape whose bottom surface is opened in an expanded state. The sheet main body S ₁ that is slightly similar in plan view to the load J ₁ of the smallest plane size that can be covered, and each of the four side portions 2a and 2b of the sheet main body S ₁ In order to maintain the overall shape of the sheet main body S ₁ when the worker M lifts it alone, the frames F ₁ and F ₂ are formed of wires that are independently and integrally attached to the side portions 2a and 2b. The sheet main body S ₁ is inserted into belt loops 3 provided in plural (two in the embodiment) on the outside of the side surface portions 2a, 2b of the sheet main body S ₁ so that the loaded body J ₁ covers the sheet main body S _1. in covered was state, elongated portion of the circumferential direction the sheet body S ₁ The thereby enabling absorption and a binding belt V for the loading cargo J ₁ to the binding state.

The seat body S ₁ has a rectangular lid shape with an open bottom (opened state), and has a portion where the frames F ₁ and F ₂ are not disposed along the circumferential direction. By using the surplus length portion T, the same load collapse prevention tool P ₁ can bind a plurality of loaded packages J ₁ having different plane sizes within a certain range. Further, the height dimension of the seat body S ₁ (H), for example as shown in FIG. 1, when the baggage is loaded in a two-stage on the pallet K is of the loading cargo J ₁ It is necessary to have a length that spans each level (reaches the lower level package). The overall shape of the loaded luggage J ₁ is often a rectangular parallelepiped, and in the embodiment, the lengths of two sides constituting the square are different in plan view. Therefore, a total of four side portions 2a of the seat body S _1, of 2b, in a side portion 2a of the long side lengths (L _1), the side surface portion 2b of the short sides of the length (L ₂₎ is, The lengths of the frames F ₁ and F ₂ for holding the rectangular shapes of the side surfaces 2a and 2b are different. Although the lengths (L ₁₃ ) of the short sides of the frames F ₁ and F ₂ are equal, the lengths of the long sides are different and the lengths of the long sides (L _{11) of the} frames F ₁ and F ₂ are different. , L _12), respectively corresponding sheet body S ₁ of side portions 2a, it is shorter by a predetermined length relative to the length of the long side of the _{2b (L 1, L 2)} , thereby the seat body S ₁ The extra length portion T is formed along the circumferential direction. That is, the surplus length portion T is a portion where the frames F ₁ and F ₂ are not disposed along the circumferential direction of the side surface portions 2a and 2b of the seat body S ₁ , and the presence of the surplus length portion T. The same load collapse prevention tool P ₁ makes it possible to prevent the load collapse of the loaded packages J _{1 having} different square sizes in a plan view within a certain range. Frames F ₁ and F ₂ are attached to the long and short side surfaces 2a and 2b, respectively. As shown in FIG. 3, the short side portions F ₁ a adjacent to each other of the frames F ₁ and F _{2 having} different lengths are connected to each other via a plurality of connecting bodies 4 so as to be rotatable. As will be described later, this connecting structure facilitates the folding operation when the sheet body S ₁ is folded into a plate shape, and stabilizes the folded shape of the sheet body S ₁ . The frames F ₁ and F ₂ are attached to the side surface portions 2a and 2b of the seat body S ₁ by sewing. That is, the straight line portions except for the corner portions of the frames F ₁ and F ₂ are covered with the mounting cloth portion 5 including the short side portion F ₁ a connected to the other adjacent frames F ₂ and F _1. As a result, the short sides F ₁ a and the long sides F ₁ b of the frames F ₁ and F ₂ are sewn in a cylindrical shape on the side surfaces 2 a and 2 b of the seat body S _1. The frame F ₁ and F ₂ are not exposed except for the corners. The mounting positions of the frames F ₁ and F _{2 in} the height direction with respect to the side surfaces 2a and 2b of the seat body S ₁ are the lower side portions of the side surfaces 2a and 2b and the lengths below the frames F ₁ and F _2. It is attached so that the side portion F ₁ b substantially coincides with the upper side portion of each side surface portion 2a, 2b and a predetermined distance between the long side portion F ₁ b above each frame F ₁ , F _2. By providing, interference between the corners on the upper surface of the loaded luggage J ₁ and the frames F ₁ and F ₂ attached to the side surfaces 2 a and 2 b of the seat body S ₁ is avoided.

In this way, the sheet body S ₁ can theoretically become a rectangular lid shape in the expanded state, but in reality, it is extremely difficult to easily lose its shape and hold the rectangular lid shape, and only one operator can Thus, it is extremely difficult to spread and cover the sheet main body S ₁ on the rectangular parallelepiped loaded luggage J ₁ . However, according to the first aspect of the present invention, as described above, since the frames F ₁ and F ₂ made of wire are attached to all the side portions 2a and 2b of the sheet body S ₁ , the side portions 2a and 2b are provided. It is possible to hold the square shape. Each frames F ₁ disposed adjacent, F _2, since the portions facing in a direction along the diagonal in plan view is pivotally connected to one another by a plurality of connector 4, the seat body S ₁ In addition to the fact that each side surface portion 2a, 2b can easily hold a square shape alone, each of the two adjacent side surface portions 2a, 2b has a rectangular frame F ₁ attached to each of the side surface portions 2a, 2b. , F ₂ are connected by the short side portions F ₁ a, F ₂ a, and thus are connected following the connection state of the frames F ₁ , F ₂ . Therefore, when the expanded sheet body S _1, even if the operator M is one person is allowed to hold the sheet body S ₁ into a square lid-like.

Further, the portions of the side surfaces 2a and 2b of the seat body S ₁ that are inside the frames F ₁ and F ₂ and that are close to the short sides F ₁ a and F ₂ a of the frames F ₁ and F _2. Each of the belt loops 3 is sewn, and the binding belt V is inserted into each belt loop 3. In an embodiment, each side portion 2a of the seat body S _1, 1 This binding belt V is located in the center of the height direction of 2b, by the binding belt V, and the load cargo J _1, the loading cargo J _The sheet main body S ₁ covered by ₁ is integrally bound to prevent the collapse of the load. However, when the loaded luggage J ₁ has two or more stages, it is along the height direction. It is desirable to arrange the binding belt V at a plurality of different locations. The length of the binding belt V is longer than the peripheral length of the load having the maximum peripheral length that can be bound by the load collapse prevention tool P ₁ by a length corresponding to the tightening allowance. The part is integrally provided with a buckle part 6 for inserting and fixing the other end of the binding belt V.

In addition, the load collapse prevention device P _{1 according} to the invention of claim ₁ is loaded on the pallet K by one worker M while the worker M is standing on any one side of the pallet K. without Liaoning around luggage J ₁ was, in addition to there is a large feature that can be put covered with respect to the loading cargo J _1, the sheet body S ₁ whose shape is composed of amorphous sheet Another feature exists in that the worker M is also devised to be folded into a plate shape. That is, as will be described in detail later, frames F ₁ and F ₂ are respectively attached to the side surface portions 2a and 2b of the sheet body S ₁ so that the planar shape can be easily maintained, and the adjacent side surface portions 2a and 2b frame F _1, F ₂ attached to 2b are adjacent each short side portions F ₁ a, the F ₂ a is are rotatably connected to each other, each side portion 2a of the seat body S _1, 2b circumference of The length in the direction is slightly shorter than the lengths of the long sides F ₁ b and F ₂ b of the frames F ₁ and F ₂ , and the extra length T in the circumferential direction of the sheet body S _1. in addition to but are formed, in the initial folding of the seat body S _1, by one worker M, in a state where the seat body S ₁ is being spread into a square lid-like, each side portion 2a, 2b Each top surface grip piece is placed on the top surface portion 1 and the specific side surface portion 2b so that two sheets can be easily stacked. It provided 1 and side gripping piece 12, by that is to facilitate the two-ply, so as to facilitate the folding of the sheet body S _1.

Namely, as shown in FIGS. 1 to 4, in the center of the top surface 1 of the seat body S _1, when folding the seat body S _1, the top portion 1 sinks downward, the folding A top surface gripping piece 11 for preventing obstruction is attached, and a rectangular lid shape is formed on the portion of the extra length portion T of the side portion 2b having a short long side which is the length along the circumferential direction. A side gripping piece 12 serving as a mark when a part of the spread sheet body S ₁ is pushed inward and two adjacent side parts 2 a and 2 b of the sheet body S ₁ are stacked is attached. Yes.

Then, in order to cover the loaded body J ₁ on the pallet K with the sheet body S ₁ of the load collapse prevention tool P _{1 and} prevent the loaded luggage J ₁ from collapsing, the following is performed. First, as shown in FIG. 2, by expanding a sheet body S _1, keep the rectangular cap-like. Square frames F ₁ and F ₂ made of wire are attached to the side surfaces 2a and 2b of the sheet body S ₁ , respectively, and the rectangular shapes of the side surfaces 2a and 2b that cannot hold the rectangular shape as they are. In addition, the short sides F ₁ a and F ₂ a of the frames F ₁ and F _{2 at} the corners in the diagonal direction where the extra length T is not provided in plan view are They are connected to each other via a plurality of connecting bodies 4 so as to be able to rotate with each other, thereby raising the standing property of the portions. For this reason, when the sheet body S ₁ is expanded in a rectangular lid shape, the sheet body S ₁ can be maintained without breaking the rectangular lid-shaped three-dimensional shape. Therefore, as shown in FIG. 4, single worker M specific side portion of the pallet K (in the case of the embodiment, a rectangular parallelepiped shape in plan view of the loading cargo J ₁ side part of the short side) in standing, lift the seat body S ₁ above the loading cargo J ₁ by grasping the long sides F ₁ b of frames F ₁ of the side portion 2a of the seat body S ₁ by both hands, as it is to the loading cargo J ₁ Cover it. The seat body S ₁ maintains its three-dimensional shape without breaking its rectangular lid shape, and the operator M can use both hands to move the long side portion of the frame F _{1 on} the side surface portion 2a of the seat body S _1. By grasping F ₁ b, it is possible to stably grasp the sheet body S ₁ expanded in the shape of a rectangular lid, so that the sheet body S ₁ is in a stable posture with respect to the load J ₁ on the pallet K. Moreover, it can be easily covered. Accordingly, the worker M does not have to go around the loaded luggage J ₁ on the pallet K like the conventional various load collapse prevention tools while standing on a specific side of the pallet K. The sheet body S ₁ can be covered over the loaded luggage J ₁ with time and reliability. Finally, when the extra length of the binding belt V is pulled and tightened at the buckle portion 6 of the binding belt V, the load collapse of the loaded luggage J ₁ is prevented by the covered sheet body S ₁ (FIG. 1). reference). Note that the loaded luggage J ₁ is not limited to being placed on the pallet K, but may be loaded on a carriage or on the loading platform of the vehicle.

Further, the sheet body S ₁ is an adaptable to the loading cargo J ₁ of maximum size in a plan view, in the case of the loading cargo J ₁ is present along one diagonal direction in a plan view The extra-long portion T covers the vertical corner J ₁ a in _one diagonal direction of the loaded luggage J ₁ [see FIG. 5A]. Therefore, the same sheet body S _1, and overmolded in a small loading cargo J ₁ 'plane size for loading cargo J _1, as in the case to prevent collapsing is that shown in FIG. 5 (b) Moreover, the extra length portion T in the circumferential direction of the sheet main body S ₁ becomes extra length and does not contribute to binding. A loaded baggage J ₁ ′ shown in FIG. 5B is a minimum plane size baggage that can be prevented from collapsing by the seat body S ₁ . In FIG. 5B, the extra length portion T of the sheet main body S ₁ is shown not only by a solid line but also by a two-dot chain line in order to clarify its existence.

Next, with reference to FIG. 6 to FIG. 10 (B), the case to be folded of the sheet body S ₁ of stabilizing cargo device P ₁ will be described when not in use. FIG. 6 is a perspective view showing an initial state in which the sheet body S ₁ developed in a rectangular lid shape is held by holding the top and side gripping pieces 11 and 12, and FIG. 7 is a view showing the sheet body S _1. FIG. 8 is a perspective view of a state in which two adjacent side portions 2a and 2b are stacked, and FIG. 8 is a top surface portion that is folded in two in a state in which two adjacent side portions 2a and 2b are stacked. FIG. 9 is a perspective view of the seat body S in a state in which the top surface portion 1 that is folded in four is sandwiched between the side surface portions 2a and 2b that are overlapped. ₁ of each of the four side portions 2a, 2b is a perspective view of a four-ply state, (a) in FIG. 10-a, (b), each side surface portions 2a of adjacent sheet body S ₁ respectively, FIG. 3 is a schematic diagram before and after pushing one extra length portion T of the sheet main body S ₁ inward in order to overlap two sheets 2b. , (C) in FIG. 10-B, (d), the 2-ply sheets body S ₁ adjacent each side portions 2a, across the top surface portion 1 which is fourfold during 2b, the four It is a schematic diagram before and after making each side part 2a, 2b overlap.

First, in the state where the sheet body S ₁ shown in FIG. 10A is opened in a rectangular lid shape, as shown in FIG. 6 and FIG. When the top gripping piece 11 of the top face portion 1 of the sheet body S ₁ is gripped with one hand, and the side gripping piece 12 portion of the side face portion 2b is pushed inward with the other hand, each adjacent frame F _1, short sides F ₁ a of F _2, and is rotated in the direction F ₂ each around the frame connecting portion 21 which connects the a frame F _1, F ₂ is two-ply, 7 and as shown by (c) in FIG. 10-B, each frame F _1, are attached to F ₂ sheet body S ₁ of side portions 2a, 2b is 2-ply. Here, in the top surface portion 1 in which the four side portions are connected to the upper side portions of the four side surface portions 2a and 2b, the diagonal direction portion connecting the frame connection portions 21 is slightly shortened, and the diagonal direction portion is connected. It will be folded in two with the part at the center. Note that the length along the diagonal direction of the top surface portion 1 of the seat body S ₁ is (L ₃ ) (see (a) of FIG. 10-A), and each frame F _{1 in} the state where the seat body S ₁ is expanded. , F ₂ , and the distance to the top surface portion 1 is H ′ (see FIG. 2), the top surface portion 1 shown in FIG. The length of the bottom side in the shape is approximately (L ₃ + 2H ′). Here, the side surfaces 2a and 2b retained by the frames F ₁ and F ₂ can be overlapped as described above, but the frames F ₁ and F _{2 on the} top surface 1 can be overlapped. Since the length between the end portions on the surplus length portion T side does not become longer than the length in the state where the sheet body S ₁ is expanded, the side surfaces held by the respective frames F ₁ and F ₂ The parts 2a and 2b cannot be expanded in a planar shape. However, in the portion where the surplus length portion 5 is provided, as shown in FIG. 10A (b), the adjacent F ₁ and F ₂ can be approached in the long side direction via the surplus length portion 5. Therefore, the two side surfaces ₂ to which the adjacent F ₁ and F _{2 that} are adjacent via the extra length 5 are attached can be overlapped.

Next, as shown in FIG. 8, the two top surface portions 2 a and 2 b are overlapped with each other, and the top surface portion 1 ′ in a folded state is set to 2 in the middle. As shown in (d) of FIG. 9 and FIG. 10-B, it is sandwiched between two sets of two side portions 2a and 2b, and a total of four side portions 2a and 2b are stacked. And In FIG. 10-B (d), 1 ″ indicates that the top surface portion 1 ′, which has been formed into an isosceles triangle shape by folding in half, is further folded in two, thereby folding the top surface portion 1 of the original square shape into four. In this way, when the sheet body S ₁ expanded in the shape of a square lid is regularly folded according to the above order, the sheet body in the form of a square lid is simply opened by one worker M. S ₁ can be folded into a square plate having a size substantially equal to the size of the frame F _{1. In} this way, the sheet main body S ₁ can be folded into a square plate by stacking four side portions 2a and 2b. What can be done is that square frames F ₁ and F ₂ are attached to the side surfaces 2a and 2b of the sheet body S ₁ to maintain the square shape, and each of the two adjacent rectangular frame shapes can be maintained. frame F _1, F ₂ are each other in the short side portion F ₁ a, F ₂ a Due to being pivotally connected to. Each side portion 2a, also in folded condition by 2b in four overlapping, the portion enclosed by a rectangular frame-shaped frames of F _1, F ₂ is , and it remained sheet, so minimizing the overall increase in weight of the seat body S _1, handling in the state in which the seat body S ₁ is folded is easy. Further, the sheet body S ₁ is is provided with the top surface portion 1, a loading luggage J ₁ while preventing collapse of cargo be placed outdoors, to protect the loading cargo J ₁ from rain water or the like.
