Summary of the Invention

Problems to be Solved by the Invention

[0008] The Linen wagon for transporting supplies described in the above-mentioned patent document is excellent in that it can store sufficient linen supplies in the linen supply storage bag during use and can be folded and stored in a narrow space when not in use (storage). However, the following points can be cited as problems.

[0009] Specifically, when taking out the linen supplies before cleaning from the supply storage bag at a linen supply cleaning factory, the operator takes out a large amount from the supply storage bag (hereinafter, simply referred to as the "storage bag" as appropriate). As the supplies are taken out, the linen supplies stored in the storage bag are in a state of being stored at a depth near the bottom surface of the bag.

[0010] When taking out these linen supplies near the bottom, the operator has to stretch his hand to the back of the storage bag with his whole body in an awkward position to take out the linen supplies stored near the bottom surface of the bag.

[0011] That is, every time a linen item stored near the bottom of the bag is taken out, it has to be taken out in an unnatural posture of the body each time. Repeating the operation of forcibly taking out the linen item from the bottom of the storage bag and repeatedly inserting it into the inlet of the linen item cleaning facility increases the physical burden on the operator, leading to work fatigue, and currently, there is a problem that the hands and waist are injured by taking an unnatural posture.

[0012] Also, after using the above-described wagon for transporting linen item storage bags, a number of wagons for transporting linen item storage bags are folded and stored in a predetermined storage space as narrow as possible, and then stored and carried out again from the storage space as needed and unfolded before use.

[0013] However, since the cleaning of linen items naturally has to be carried out frequently, it is necessary to perform the operation of pulling out the folded wagon for transporting linen item storage bags from the wagon storage room and unfolding it into a form that can accommodate the wagon for transporting linen item storage bags every time. At this time, if it has a form like that of the above-mentioned patent document, when returning to the wagon form, the space between the two frame bodies at the center of the bottom plate equivalent part that is open upward when folded will be completely and perfectly closed.

[0014] At that time, the problem is that when an operator using the wagon hurriedly unfolds the folded wagon for transporting linen item storage bags due to time constraints and tries to push it open by applying force with the palm or fingers, there is a risk of accidentally pinching the palm or fingertips into the space formed between these frame bodies and causing unexpected injuries or accidents when this space is perfectly closed during the process of unfolding it into the wagon form.

[0015] Regarding the transportation of such linen supplies before cleaning to a linen supply cleaning factory using a wagon for transporting linen supply storage bags and then redelivery, considering the circumstances of accommodation facilities and hospitals, it is based on the inevitable condition that the cleaning work must be completed within a limited time at all times and the clean linen supplies must be delivered on time. And under this condition, the time schedule is naturally a very tight operation, and when using a wagon for transporting linen supply storage bags as described above, the deployment work becomes hasty, and the frequency of such accidents is increasing.

[0016] An object of the present invention is to solve the above-mentioned problems Linen supplies Used during cleaning while ensuring the safety of workers handling the wagon for transporting linen supply storage bags, significantly reducing the burden on the body while improving work efficiency, and Linen supplies Used during cleaning when not using the wagon for transporting linen supply storage bags, it can be folded and stored in a narrow space for many Linen supplies Used during cleaning the wagon for transporting linen supply storage bags can be stored Linen supplies Used during cleaning to provide a wagon for transporting linen supply storage bags.

Further, Fig. 8 is a plan view (Fig. 8(a)) and a perspective view (Fig. 8(b)) showing the bottom pressing part of the linen storage bag that can move up and down in the wagon according to the present invention.

[0032] Further, Fig. 9 is an enlarged perspective view showing a common engaging part that enables engagement of both a chain connecting the opposing upper parts on both sides of the chain of the wagon according to the present invention and a tension coil spring that enables the bottom pressing part of the linen storage bag to move up and down in the wagon.

[0033] The wagon 10 for transporting a linen storage bag according to the present embodiment has a box shape forming a wagon opening part that is open at the upper side in the use state, is provided with wagon moving casters 101 to 104 at a predetermined position on the lower side, and is used to transport the linen storage bag 15 and a large number of linen items stored therein.

[0034] Here, the linen items include all linen items that are used daily in accommodation facilities such as hotels and inns, hospitals, and other stores and facilities such as esthetic salons, massage salons, and hot yoga as described above, and are collectively transported to a linen cleaning factory after use and then transported back to the supplier after cleaning.

[0035] The wagon 10 for transporting a linen storage bag has a foldable bottom plate equivalent part 100 that combines a first bottom plate constituent half part 110 and a second bottom plate constituent half part 120, which have the same elongated rectangular shape, by hinges at one edge in the longitudinal direction of each bottom plate constituent half part 110, 120.

[0036] The foldable bottom plate equivalent part 100 includes a first bottom plate constituent half part 110, a second Bottom plate structure of bottom plate constituent half part 120, and a hinge 150 that connects these bottom plate constituent half parts 110, 120 to each other. The first bottom plate constituent half part 110 is configured by integrating an elongated rectangular outer frame part made of a square pipe and a square pipe that connects the opposing long sides of the outer frame part.

[0037] Also, the second Bottom plate structure ofThe second half part 120 has the same structure as the first bottom plate component half part 110. That is, the second Bottom plate structure of The second half part 120 is composed of an elongated rectangular outer frame part made of a square pipe and a square pipe connecting the opposing long sides of the outer frame part, which are integrated. And a caster mounting plate 130 for wagon movement is provided along one of the long side parts.

[0038] Both ends near the caster of the first bottom plate component half part 110 and the corresponding caster mounting plate 130 for wagon movement are rotatably connected to each other. Similarly, both ends near the caster of the second bottom plate component half part 120 and the corresponding caster mounting plate 140 for wagon movement are rotatably connected to each other (see FIGS. 1, 3 to 7, 10 to 15).

[0039] The first bottom plate component half part 110 and the second Bottom plate structure of The second half part 120 of the equivalent folding bottom plate 100 each has an elongated rectangular shape as described above. The connecting part by the hinge between the two is composed of a bar-shaped member or a pipe-shaped member with a rectangular cross-section. The hinge 150 (see FIGS. 1, 5, 6, 13 to 15, 19 to 21) uses the lower side of the bar-shaped member or the pipe-shaped member as the rotation center to form the equivalent folding bottom plate 100 in the same plane.

[0040] In addition, when the wagon 10 for transporting linen product storage bags is not in use, the first bottom plate component half part 110 and the second bottom plate component half part 120 are bent in a V shape, so that a gap space (see the space S1 in FIG. 6) is generated in the upper part of the bar-shaped members or the pipe-shaped members connected by the hinge 150 over the entire longitudinal direction, and a space closing cover 190 that closes all the gap spaces generated by the V-shaped bending state of the bar-shaped members or the pipe-shaped members is provided on the upper part of the bar-shaped members or the pipe-shaped members (see FIGS. 1, 3, 5, 6, etc.).

[0041] Note that the caster mounting plates 131, 132 (130) for wagon movement and the first bottom plate component half part 110 (100) and the second Bottom plate structure ofBoth ends of the outer frame of the half part 120 (100) are pivotally supported so as to be rotatable at a predetermined angle as described above. And the first bottom plate component half part 110 and the second Bottom plate structure of In this embodiment, the half part 120 is connected by two hinges 150 at the lower part of the square pipe so that the side surfaces of the long sides opposite to the long side where the caster mounting plate 130 for wagon movement is attached abut each other (see FIGS. 6, 13 to 15).

[0042] Also, the two hinges 150 serve to rotate the first bottom plate component half part 110 and the second Bottom plate structure of half part 120 within a range limited to a horizontal state and a mountain shape state when viewed from the side, enabling folding rotation.

[0043] Also, the first bottom plate component half part 110 and the second Bottom plate structure of half part 120, that is, the first bottom plate component half part 110 and the second Bottom plate structure of A tension coil spring 180 having a certain length and capable of generating a sufficient elastic tensile force is provided below the half part 120 (see FIGS. 6, 13 to 15).

[0044] More specifically, one end of this tension coil spring 180 is connected to a predetermined position below the first bottom plate component half part 110, and the other end is connected to a predetermined position below the second Bottom plate structure of half part 120.

[0045] As described above, since the hinge 150 is attached as a rotation center below the rod-shaped member or pipe-shaped member, when using the wagon, for example, by pressing down on the space closing cover 190 that covers the gap space S1 formed between the first bottom plate component half part 110 of the folded wagon 10 and the second Bottom plate structure of half part 120 with the foot or the palm to completely close it, the first bottom plate component half part 110 and the second Bottom plate structure of half part 120 are in the same plane with each other to form the folded bottom plate equivalent part 100.

[0046] On the other hand, when the wagon 10 for transporting linen supply bags is not in use, the first bottom plate component half 110 and the second Bottom plate structure of component half 120 are bent in a V-shape with the hinge 150 as the rotation center (see FIGS. 5 and 6).

[0047] That is, when the wagon 10 is folded, a gap space S1 is formed over the entire longitudinal direction on the upper side between the rod-shaped members or pipe-shaped members joined by the hinge 150. However, when the first bottom plate component half 110 made of a U-shaped pipe member and the second Bottom plate structure of component half 120 are simultaneously pressed downward, this gap space S1 disappears, and as a result, a portion corresponding to the folded bottom plate 100 is formed.

[0048] And while the gap space S1 exists, the gap space S1 formed between the first bottom plate component half 110 and the second Bottom plate structure of component half 120 is entirely covered from above by the space closing cover 190. Therefore, in order to change the wagon 10 from the folded state to the use state, even if one spreads the palm and forcibly presses downward at this part, there is an important advantage point of the present invention that prevents a part of the palm from being accidentally pinched or a little finger that has inadvertently entered the space from being pinched, causing an unexpected serious injury to the wagon user.

[0049] Note that the fixing screw 491 shown in the figure fixes the space closing cover 490 to either one of the bottom plate component halves (the first bottom plate component half 110 in the drawing) so that the space closing cover 190 surely covers and closes the entire gap space during the process of the wagon 10 changing from the folded state to the unfolded state. In this embodiment, when closing the gap space S1, the free end on the side opposite to the fixing screw 491 side of the gap space closing cover 490 is shifted horizontally (slides) to close this gap space S1.

[0050] In addition, the wagon 10 for transporting linen supply bags includes the first and second Bottom plate structure ofThe first side plate equivalent part 210 and the second side plate equivalent part 220 stand up from the edges of the opposite bottom plate component halves that are parallel in the longitudinal direction and are connected by the hinge 150 of the half parts 110, 120, and their upper edges are configured to form the opposing edges of the wagon opening 11.

[0051] The specific configurations of the side plate equivalent parts 210, 220 that are oppositely arranged in a standing state across the bottom plate equivalent part 100 will be described below. The oppositely standing side plate equivalent parts 210, 220 are made of the same constituent members, and include a horizontally long rectangular inverted U-shaped outer frame standing part made of a round pipe, and a plurality of inner standing parts that stand up at a predetermined interval inside the outer frame standing part in the same manner as the outer frame standing part and are integrally configured (see Figure 1).

[0052] As can be seen from Figure 1, the lower end parts of each of the two outer standing parts are firmly connected to one caster fixing plate 131(130) and the other caster fixing plate 132(130) respectively.

[0053] Also, as shown in Figure 1, at each one end side of the two outer standing parts, there are provided chains 315 that are connected to each of these one end sides while slightly hanging down in the wagon use state. Similarly, at each other end side of the two outer standing parts, there are also provided chains 325 that are connected to each of these other end sides while slightly hanging down in the wagon use state.

[0054] In addition, the linen supplies storage bag transport wagon 10 is provided with a first foldable side connection part 310 and a second foldable side connection part 320 that can narrow the interval between the first side plate equivalent part 210 and the second side plate equivalent part 220 at both ends in the width direction of these two opposing side plate equivalent parts 210, 220 to be narrower than the interval in the use state (see Figures 1 to 6).

[0055] And, as described above, the first bottom plate component half 110 and the second Bottom plate structure ofThe half part 120 is bent into a chevron shape when viewed from its longitudinal side surface, and by pressing and shrinking the first foldable side connection part 310 and the second foldable side connection part 320 in the width direction, the wagon 10 for transporting linen product storage bags that forms a box shape in the use state can be folded and stored in a narrow space while remaining in the unused state (see FIGS. 5 and 6).

[0056] Hereinafter, the specific configurations of the first foldable side connection part 310 and the second foldable side connection part 320 will be described. Since the first foldable side connection part 310 and the second foldable side connection part 320 have the same configuration as each other, the configuration of the former first foldable side connection part 310 will be described.

[0057] In the present embodiment, the first foldable side connection part 310 is configured by rotatably connecting four elongated link members (elongated metal plates) 311, 312, 313, 314 having sufficient thickness with excellent strength and durability so as to form a telescopic link in a so-called pantograph form (see FIGS. 1 to 6).

[0058] And, for example, the ends of the upper and lower link members 311, 312 on the front side of the first foldable side connection part 310 shown in FIG. 1 are rotatably supported above and below the front side of the outer frame part of the front side side plate equivalent part 210 shown in FIG. 1. Also, the ends of the upper and lower link members on the opposite side of the first foldable side connection part 310 are rotatably supported above and below the front side of the outer frame part of the opposite side side plate equivalent part 220 (see FIGS. 1 to 6).

[0059] Similarly, the second foldable side connection part 320 also has the same configuration as the first foldable side connection part 310 as described above, and is rotatably supported above and below the left side of the outer frame part of the front side side plate equivalent part 210, and is rotatably supported above and below the left side of the outer frame part of the front side side plate equivalent part 220 (see FIGS. 1 to 6).

[0060] At the rotatable joints of the link members 311 to 314 and 321 to 324 that respectively constitute the first foldable side connection part 310 and the second foldable side connection part 320, in particular, at four rotatable joints located near the middle in the height direction of the wagon, there are provided sandwiching prevention members 390 (Figs. 5, 6, 10 to 15).

[0061] The sandwiching prevention member 390 is composed of a disc-shaped spacer 390 such as a washer having a certain thickness and a large outer diameter, and is sandwiched at the rotatable joints of the respective link members.

[0062] Incidentally, the sandwiching prevention member 390 is sandwiched between these link members 311 to 314 so as not to hinder the movement of the rotatable joints of the link members 311 to 314 provided with this sandwiching prevention member 390 when the first foldable side connection part 310 and the second foldable side connection part 320 are expanded and contracted.

[0063] The wagon 10 for transporting the linen goods storage bag further has a portion 400 corresponding to the bottom support plate of the linen goods storage bag. The portion 400 corresponding to the bottom support plate of the linen goods storage bag has the same structure as the foldable bottom plate corresponding portion 100 composed of the first bottom support plate constituting half portion 410 and the second bottom support plate constituting half portion 420 inside the wagon 10 for transporting the linen goods storage bag.

[0064] Regarding the structure of the portion 400 corresponding to the bottom support plate of the linen goods storage bag, when folding this when the wagon 10 for transporting the linen goods storage bag is not in use, the foldable bottom plate corresponding portion 100 is folded so as to form a mountain shape when viewed from the side, and at the same time, the portion 400 corresponding to the bottom support plate of the linen goods storage bag is also folded so as to form a mountain shape when viewed from the side.

[0065] And the overall size of the portion 400 corresponding to the bottom support plate of the linen goods storage bag can be moved up and down in a state facing the foldable bottom plate corresponding portion 100 inside the wagon during the use of the wagon 10 for transporting the linen goods storage bag.

[0066] In addition, the portion 400 corresponding to the bottom support plate of the linen article storage bag, when the linen article storage bag 15 is stored in the wagon with a predetermined portion of the bag opening of the storage bag engaged with a predetermined portion of the wagon opening 11, even when the linen articles 21 before cleaning are stuffed into the linen article storage bag 15 to the fullest, has a size and strength sufficient to support and hold the bottom of the linen article storage bag.

[0067] The first bag bottom support plate component half 410 and the second bag bottom support plate component half 420 of the portion 400 corresponding to the bottom support plate of the linen article storage bag each have an elongated rectangular frame shape, and the connecting portion by the hinge 450 between the two is composed of a bar-shaped member or a pipe-shaped member with a rectangular cross-section.

[0068] The hinge 450 is centered on the lower side of the bar-shaped member or the pipe-shaped member and forms the portion 400 corresponding to the bottom support plate of the linen article storage bag in the same plane with each other. When the wagon 10 for transporting the linen article storage bag is not in use, by folding the first bag bottom support plate component half 410 and the second bag bottom support plate component half 420 in a V-shape, a gap space S2 is formed over the entire longitudinal direction between the upper portions of the bar-shaped member or the pipe-shaped member connected by the hinge 150. And an enclosure cover 490 is provided on the upper portion of the bar-shaped member or the pipe-shaped member to block all of the gap space S2 generated by these V-shaped folding states.

[0069] Also, on the lower sides of the first bag bottom support plate component half 410 and the second bag bottom support plate component half 420 on the side where two hinges 450 that serve to make the first bag bottom support plate component half 410 and the second bag bottom support plate component half 420 rotatable between a horizontal state and a V-shape when viewed from the side are attached, a tension coil spring 480 having a certain length and capable of generating a sufficient elastic tensile force is provided.

[0070] More specifically, one end of the tension coil spring 480 is connected to a predetermined position below the first bottom support plate component half 410, and the other end is connected to a predetermined position below the second bottom support plate component half 420 (see FIGS. 6, 13 to 15).

[0071] Subsequently, the detailed configuration of the portion 400 corresponding to the bottom support plate of the present embodiment, that is, the specific configurations of the first bottom support component half 410 and the second bottom support component half 420 that are these components, will be described. The portion 400 corresponding to the bottom support plate has the same configuration as the folded bottom plate corresponding portion 100 described above, but its overall size fits inside the wagon when the wagon is in use, and in the case of the present embodiment, it has a size that can move up and down while supporting the bottom of the linen storage bag via an elastic member composed of four tension coil springs 510 to 540 (500), and there is a main dimensional difference between the two in this regard.

[0072] More specifically, the portion 400 corresponding to the bottom support plate includes the first bottom support component half 410 and the second bottom support component half 420 that constitute it, and a hinge 150 that connects these bottom support component halves to each other. The first bottom support component half 410 is configured by integrating an elongated rectangular outer frame portion made of a square pipe and a square pipe that connects the opposing long sides of the outer frame portion.

[0073] Also, the second bottom support component half 420 has the same structure as the first bottom support component half 410. Specifically, the second bottom support component half 420 is configured by integrating an elongated rectangular outer frame portion made of a square pipe and a square pipe that connects the opposing long sides of the outer frame portion.

[0074] And the first bottom support component half 410 and the second bottom support component half 420 are connected by a hinge 450 in the present embodiment at the lower portion of the square pipe such that the side surfaces of one long side portion of each contact each other (see FIGS. 6, 13 to 15).

[0075] As described above, since the hinge 450 is attached with the lower side of the rod-shaped member or the pipe-shaped member as the rotation center, when using the wagon, for example, by pressing down the space closing cover 190 that covers the gap space S2 formed between the first bottom bag support configuration half 410 and the second bottom bag support configuration half 420 that constitute the corresponding part 400 of the bag bottom support plate with the palm of the hand, the first bottom bag support configuration half 410 and the second bottom bag support configuration half 420 can be easily formed into the form of the corresponding part 400 of the bag bottom support plate with the same planar shape.

[0076] That is, when the linen storage bag transport wagon 10 is not in use, the first bottom bag support configuration half 410 and the second bottom bag support configuration half 420 are bent in a mountain shape with the hinge 450 as the rotation center. Note that a gap space S2 is generated over the entire longitudinal direction between the upper parts of the rod-shaped member or the pipe-shaped member connected by the hinge 450.

[0077] However, when simultaneously pressing down the first bottom bag support configuration half 410 and the second bottom bag support configuration half 420 made of angular pipe-shaped members, this gap space disappears. As a result, when forming the corresponding part 400 of the bag bottom support plate, the gap space S2 formed between the first bottom bag support configuration half 410 and the second bottom bag support configuration half 420 is entirely covered from above by the space closing cover 490.

[0078] This prevents a part of the bottom fabric of the linen storage bag 15 and the net (mesh) at the bottom of the linen storage bag 16 made of a net-like (mesh-like) shape described later from being pinched and damaged or torn during the process where the gap space S2 is gradually narrowed and disappears as the wagon is deployed with a part of them entering the gap space S2.

[0079] Note that the fixing screw 491 shown in the figure fixes the space-blocking cover 490 to either one of the half parts of the bag bottom support structure (the first half part 410 of the bag bottom support structure in the drawing), so that the space-blocking cover 490 can surely cover and block the entire gap space during the process of the wagon 10 changing from the folded state to the unfolded state. In this embodiment, when closing the gap space S2, the free end on the side opposite to the fixing screw 491 side of the gap space-blocking cover 490 is laterally displaced (slid) to close the gap space S2.

[0080] In addition, the wagon 10 for transporting the linen article storage bag has four elastic suspension members 510 to 540 (500) having a certain elastic force. The four elastic suspension members 510 to 540 (500) each serve to enable vertical movement inside the wagon 10 for transporting the linen article storage bag while maintaining a state in which the bottom support plate equivalent part 400 of the linen article storage bag is disposed substantially parallel to and facing the folded bottom plate equivalent part 100 in the use state of the wagon 10 for transporting the linen article storage bag (see other drawings except FIGS. 7 and 8).

[0081] To surely realize this operation, both ends of the four elastic suspension members 510 to 540 (500) are connected to four different predetermined positions, namely, a predetermined position of the bottom support plate equivalent part 400 of the linen article storage bag and three other predetermined positions formed on the upper side of the wagon opening 11 of the wagon for transporting the linen article storage bag.

[0082] More specifically, the specific configuration of the four elastic suspension members 510 to 540 (500) will be described. In the case of this embodiment, tension coil springs 510, 520, 530, and 540 are used as the specific configuration of the four elastic suspension members 510 to 540 (500). The upper ends of the respective tension coil springs 510 to 540 (500) are firmly hooked and fixed to the wagon component engagement parts 211, 221, 212, and 222 described below, and the lower ends are firmly hooked and fixed to the four corners of the bottom support plate equivalent part 400 of the linen article storage bag one by one (see FIGS. 1, 3 to 5, and 9).

[0083] The elastic forces of the tension coil springs 510, 520, 530, and 540, which are elastic suspension members, will be described below. Regarding this elastic force, in the case of this embodiment, the upper end portions of the four tension coil springs 510, 520, 530, and 540 are respectively hooked and fixed to the wagon component engagement portions 211, 221, 212, and 222 formed at both ends of the left and right outer frame standing portions. At the same time, the lower end portions are firmly hooked and fixed to the engagement hooks provided at the four corners of the upper opening of the linen article storage bag, and the description will be made on the premise that the linen article storage bag is suspended and held inside the wagon 10 for transporting linen articles.

[0084] The elastic force of the elastic suspension member 500 is such that when linen articles before cleaning (especially those containing a large amount of moisture) are put into the linen article storage bag attached to the wagon 10 for transporting linen articles during use, as the amount of the linen articles put in increases according to the amount, the bottom surface support plate equivalent portion 400 of the linen article storage bag descends toward the folding bottom plate equivalent portion 100 of the wagon 10 for transporting linen articles. Also, each time linen articles are taken out from the linen article storage bag, as the amount of the remaining linen articles stored in the linen article storage bag decreases, the bottom surface support plate equivalent portion 400 of the linen article storage bag rises toward the wagon opening 11 of the wagon 10 for transporting linen articles, and it has an elastic force suitable for this (see FIGS. 10 to 21, which are explanatory diagrams of the operation of the present invention).

[0085] Further, the wagon 10 for transporting linen article storage bags is provided with the wagon component engagement portions 211, 221, 212, and 222 at four different predetermined positions at the opening 11 above the wagon for transporting linen article storage bags. The wagon component engagement portions 211, 221, 212, and 222 serve to take in and out the linen article storage bag 15 from the wagon opening 11 of the wagon 10 for transporting linen article storage bags, and to make it possible to accommodate the linen article storage bag inside with the bag opening of the linen article storage bag widened over the entire wagon opening 11 through the hook provided at the bag opening of this linen article storage bag (see, for example, FIGS. 1, 3 to 5, and 9).

[0086] Next, the specific configurations of the wagon component engaging portions 211, 221, 212, and 222 will be described below. In the case of this embodiment, the wagon component engaging portions 211, 221, 212, and 222 are, with respect to each elastic suspension member 500 (510, 520, 530, 540), an engaging portion provided near the upper opening of the linen storage bag carrying wagon 10, and a common engaging portion 210 for hooking the opening edge portion of the linen storage bag 15 to the upper opening of the linen storage bag carrying wagon 10, and is provided at a predetermined position near the upper opening of the linen storage bag carrying wagon 10 (see FIG. 9 which shows an enlarged view of this configuration).

[0087] In the case of this embodiment, the wagon component engaging portions 211, 221, 212, and 222 are provided integrally with the first side plate equivalent portion 210 and the second side plate equivalent portion 220 near the upper bent portion of the outer frame standing portion of the first side plate equivalent portion 210 and near the upper bent portion of the outer frame standing portion of the second side plate equivalent portion 220.

[0088] Also, each end of the first connecting chain 315 and the second connecting chain 325 is connected to the wagon component engaging portions 211, 221, 212, and 222. That is, at the common coupling portions 211, 221 corresponding to the first foldable side connection portion 310 of the linen storage bag carrying wagon 10, both ends of the first connecting chain 315 can be engaged in a state where the first connecting chain 315 is pulled at both upper ends, and at the common coupling portions 212, 222 corresponding to the second foldable side connection portion 320, both ends of the second connecting chain 325 can be engaged in a state where the second connecting chain 325 is pulled at both upper ends.

[0089] Also, the four wagon component engaging portions 211, 221, 212, and 222 are firmly hooked and fixed to the upper portions of the tension coil springs 510, 520, 530, 540 which are the four elastic suspension members 510 to 540 (500) as described above.

[0090] The wagon 10 for transporting linen product storage bags is provided with casters 101, 102, 103, and 104 at the four corners of the corresponding part 100 of its bottom plate, that is, at the caster fixing plates 131, 132 (130) provided on both sides of the corresponding part 100 of the bottom plate. More specifically, two casters 101 and 102 are attached to both ends of the caster fixing plate 131 provided on both sides of one longitudinal side of the corresponding part 400 of the bottom surface support plate of the linen product storage bag. These two casters 101 and 102 are attached so that the rotation and traveling directions of the casters 102 and 103 can be freely rotated 360 degrees.

[0091] On the other hand, two casters 103 and 104 are attached to both ends of the caster fixing plate 132 provided on both sides of the other longitudinal side of the corresponding part 400 of the bottom surface support plate of the linen product storage bag. These two casters 103 and 104 are attached so as to limit the rotation and traveling directions of the casters 103 and 104 to a certain direction.

[0092] And the casters 101 to 104 for moving the wagon play the following roles. Specifically, when transporting from the collection place of linen products before cleaning to the transportation place of linen products such as a truck in the used state, or transporting to the cleaning equipment for inputting the products before cleaning after unloading this at the linen product cleaning factory, the wagon 10 for storing and transporting linen products can be easily moved. Also, when transporting the linen products after cleaning from the product unloading place of the cleaning factory to the truck, or transporting to the linen product storage place of the facility at the delivery destination after delivering by truck to the delivery destination, the wagon 10 for storing and transporting linen products plays a role of easily moving it.

[0093] Subsequently, an example of the usage procedure of the wagon 10 for transporting linen product storage bags, which can clarify the operation of the present invention, will be described. FIG. 10 is a perspective view showing a state in which a linen product storage bag made of a thick fabric or the like is attached to the wagon according to the present invention and a small amount of linen products before cleaning are collected in the first process of collecting the linen products.

[0094] FIG. 11 is a perspective view showing a state in which a linen article made of a thick fabric or the like is mounted on the wagon according to the present invention, and the linen article before cleaning is recovered up to the middle in the process of recovering the linen article before cleaning.

[0095] FIG. 12 is a perspective view showing a state in which a linen article storage bag made of a thick fabric or the like is mounted on the wagon according to the present invention, and as much linen article before cleaning as possible is recovered in the process of recovering the linen article before cleaning.

[0096] FIG. 13 is an end view partially transparently showing a state in which a linen article storage bag made of a thick fabric or the like is mounted on the wagon according to the present invention, and the folded linen article after cleaning is stored in the linen For article storage bag until the bottom pressing portion is located at the lower height.

[0097] FIG. 14 is a view corresponding to FIG. 13 showing a state in which an operator takes out and transfers about one-third of these linen For articles from the upper side of the wagon to a transport back for loading on a truck or the like, and is an end view partially transparently showing a state in which the bottom pressing portion of the linen For article storage bag has risen to the middle height.

[0098] FIG. 15 is a view corresponding to FIG. 14 showing a state in which an operator further takes out and transfers the remaining two-thirds of these linen For articles from the upper side of the wagon to a transport back for loading on a truck or the like, and is an end view partially transparently showing a state in which the bottom pressing portion of the linen For article storage bag has risen to the top height.

[0099] Assemble the wagon 10 for transporting linen storage bags, which were initially folded and stored in large quantities in a storage room, into a usable state either in the storage room or outside the storage room (refer to the change from the state shown in FIGS. 5 and 6 to the state shown in FIG. 1). At this time, in hotels, inns, large hospitals, etc., a very large number of wagons 10 for transporting linen storage bags are used at once.

[0100] For one set of the casters 101 to 104 provided on the wagon 10, the moving direction of the wagon due to the rotation of the casters 103 and 104 is determined, while for the other set, the mounting parts of the casters 101 and 102 can rotate freely 360 degrees with respect to the bottom plate equivalent part 100 of the wagon. With such a structure, the wagons stored in large numbers in the storage room can be efficiently taken out one by one.

[0101] Next, an explanation will be given on how to deploy the folded wagon 10 for transporting linen storage bags into a usable state. Specifically, as shown in FIG. 6, after pushing down the central part of the bottom plate equivalent part 100 bent in a mountain shape when viewed from the side with the foot from above to a certain extent, the first bottom plate component half 110 and the second Bottom plate structure of The part where the component halves 120 are joined by the hinge 150. In the case of this embodiment, the lower sides of the square pipes are joined by the hinge 150, and a vinyl sheet 190 provided on the upper surface to cover all the spaces generated between the square pipes is pressed from above, for example, with the palm of the operator's hand.

[0102] As a result, the upper surfaces of the first bottom plate component half 110 and the second Bottom plate structure of The component halves 120 are aligned to form the shape of the bottom plate equivalent part 100 corresponding to a single plate. At this time, the elastic tensile force of the coil spring 180 can be utilized to quickly form the bottom plate equivalent part 100 with a flat surface (the upper surfaces are on the same plane).

[0103] In addition, in the present embodiment, since the lower sides of the square pipes are joined by the hinge 150, all of the spaces generated between the square pipes are covered by a space closing cover 190 made of a vinyl sheet having a certain thickness and sufficient elasticity made of polyethylene or the like.

[0104] As a result, even if the space is suddenly closed by the elastic force of the tension coil spring 180 provided near the hinge portion causing the sides of the square pipes to close forcefully, for example, there is no risk of serious accidents such as the palm of a worker who has entered this space or a little finger that has been inadvertently inserted being pinched.

[0105] Regarding the portion corresponding to the bottom surface support of the storage bag as well, the process of becoming flush from the mountain shape when viewed from the side and supporting the entire bottom surface of the storage bag in the process of unfolding the wagon 10 for transporting the linen storage bag from the folded state to the usable state is the same as the folding and unfolding process of the portion corresponding to the bottom plate 100 described above.

[0106] Specifically, since the first bottom plate component half 410 and the second bottom surface support component half 420 constituting the portion corresponding to the bottom surface support of the storage bag are joined by a hinge 450, by making it flat from the mountain shape when viewed from the side, the sides of the square pipes are forcefully closed by the pulling force of the tension coil spring 460 provided near the hinge 450, and thus this space will be suddenly closed. However, since there is a vinyl sheet 490 that completely closes this space from the upper side, it is possible to prevent a part of the bottom of the linen storage bag from being suddenly pinched and damaged or broken.

[0107] After making the wagon 10 for transporting the linen storage bag usable in this way, the linen items 21 to be cleaned are successively put into the upper opening of the linen storage bag 15.

[0108] Note that, before putting the linen articles 21 to be cleaned into the linen article storage bag 15, since there is nothing in the linen article storage bag 15, only the weight of the bag is applied to the corresponding portion 400 of the storage bag bottom support of the wagon.

[0109] As a result, almost no tensile force acts on the tension coil springs 500 whose lower ends are respectively connected to the four corners of the corresponding portion 400 of the storage bag bottom support and whose upper ends are respectively connected to the common engagement portion of the wagon. As a result, the corresponding portion 400 of the storage bag bottom support of the wagon 10 is located on the upper side in the height direction of the wagon 10, and accordingly, the bottom surface of the linen article storage bag 15 is also located on the upper side of the wagon 10 (see FIG. 10).

[0110] In such an arrangement state of the corresponding portion 400 of the storage bag bottom support of the wagon 10 and the linen article storage bag 15 located above this, when the wagon user stores the linen articles 21 before cleaning in the linen article storage bag 15, as in the conventional case, the linen articles 21 are thrown or inserted to a certain extent near the bottom of the wagon 10 inside the linen article storage bag, and then, in order to increase the amount of linen articles that can be stored in one storage bag, the user does not have to take a strenuous posture and burden the body by narrowing the gaps between the linen articles stored in the lower part of the linen article storage bag 15 near the bottom plate of the wagon 10 with the palm or the like (see FIG. 10).

[0111] That is, when the wagon user stores, for example, the first one-third of the linen articles 21 before cleaning to be stored in the linen article storage bag 15 in the storage bag 15, since the corresponding portion 400 of the storage bag bottom support of the wagon 10 is located on the upper side in the height direction of the wagon 10, accordingly, the bottom surface of the linen article storage bag 15 is also located on the upper side of the wagon 10, and the linen articles 21 can be efficiently packed into the storage bag without taking a strenuous posture (see FIG. 10).

[0112] Subsequently, as the pre-cleaning linen items 21 are stored in the linen item storage bag 15 as described above, the weight of the entire linen item storage bag increases. Accordingly, the bottom surface support equivalent part 400 of the storage bag gradually descends downward against the elastic forces of the four tension coil springs 510, 520, 530, 540 (500).

[0113] In accordance with this downward movement, the linen items themselves stored in the linen item storage bag 15 are lifted up, so that the upper surface height of the linen items 21 stored in the linen item storage bag 15 is maintained at approximately the same height as the upper opening of the wagon 10 (see the change from FIG. 10 to FIG. 11).

[0114] As a result, the wagon user can always keep the body posture and orientation for storing the pre-cleaning linen items 21 in the linen item storage bag 15 constant, and there is no need to stretch the hand deep into the bag and take an uncomfortable body posture. The storage operation of the linen items 21 can be efficiently performed, and it is possible to avoid being troubled by the occurrence of low back pain, shoulder stiffness, etc. caused by the physical burden of an uncomfortable posture.

[0115] Similarly, when the wagon user stores the next one-third of the pre-cleaning linen items 21 to be stored in the linen item storage bag 15 in the storage bag 15, the bottom surface support equivalent part 400 of the storage bag of the wagon 10 slowly descends from the upper side to the lower side in the middle of the height direction of the wagon 10. Accordingly, the bottom surface of the linen item storage bag 15 also moves so as to slowly descend from the upper side to the lower side in the middle of the height direction of the wagon 10 (see the change from FIG. 11 to FIG. 12).

[0116] Thereby, the linen items themselves stored in the linen item storage bag 15 are lifted up, so that the upper surface height of the linen items 21 stored in the linen item storage bag 15 approaches the upper surface height of the linen items 21 stored in the linen item storage bag 15 for storing the next linen items 21 (see FIG. 12).

[0117] As a result, the wagon user can always keep the body posture and orientation for storing the linen articles 21 before cleaning in the linen article storage bag 15 constant, and there is no need to stretch the hand unnecessarily deep into the bag and take an awkward body posture. The storage operation of the linen articles 21 can be performed efficiently, and it is possible to avoid being troubled by the occurrence of low back pain, stiff shoulders, etc. caused by the physical burden of an awkward posture. This can be easily understood by comparing the changes from FIG. 10 to FIG. 11.

[0118] Furthermore, when the wagon user stores the remaining one-third of the linen articles 21 before cleaning to be stored in the linen article storage bag 15 in the bag, the portion 400 corresponding to the bottom surface support of the storage bag of the wagon 10 is located from the upper part to the lower part in the height direction of the wagon 10, and accordingly, the bottom surface of the linen article storage bag 15 also moves so as to be located from the upper part to the lower part in the height direction of the wagon 10. As a result, the linen articles themselves stored in the linen article storage bag 15 are lifted up, and the upper surface height of the linen articles 21 stored in the linen article storage bag 15 is kept at approximately the same height as the upper opening of the wagon 10 for the subsequent linen articles 21 to be stored in the linen article storage bag 15 (see FIG. 12).

[0119] As a result, the wagon user can always keep the body posture and orientation for storing the linen articles 21 before cleaning in the linen article storage bag 15 constant, and there is no need to stretch the hand unnecessarily deep into the bag and take an awkward body posture. The storage operation of the linen articles 21 can be performed efficiently, and it is possible to avoid being troubled by the occurrence of low back pain, stiff shoulders, etc. caused by the physical burden of an awkward posture. This can be easily understood by comparing the changes from FIG. 11 to FIG. 12.

[0120] After packing the linen articles 21 to be cleaned in this way into the linen article storage bag 15 of the wagon 10 for transporting the linen article storage bag until full, the wagon user pushes the wagon 10 and directly loads it onto a truck for transporting to a linen article cleaning factory waiting at a hotel, inn, accommodation facility, a hospital with complete inpatient facilities, etc., or repacks all of the linen articles 21 into a dedicated delivery mailing transport bag and loads it onto the truck.

[0121] Such linen supplies 21 to be cleaned usually amount to a large quantity and thus usually cannot be fully accommodated in a single wagon 10. Therefore, in order to repeat the above operations and transport all the wagons 10 for carrying linen supply bags to the cleaning factory by truck, all the wagons 10 are loaded onto the truck.

[0122] In addition to the above, the present invention can prevent unexpected accidents from occurring when collecting the linen supplies 21 before cleaning by the wagon 10 for carrying linen supply bags. Specifically, of the casters 131, 132 (130) provided at the bottom of the wagon 10 for carrying linen supply bags, two casters (for example, casters 101, 102) respectively fixed to one end of each have a predetermined rotation and traveling direction, while two casters (for example, casters 103, 104) respectively fixed to the other end of the fixing plates 131, 132 (130) are provided so that their rotation and traveling direction can be freely changed by 360 degrees.

[0123] Therefore, it is possible to prevent the wagon 10 for carrying linen supply bags from accidentally hitting hotel guests or other accommodation guests in hotels, inns, etc. during transportation, or hitting a part of the accommodation facilities. Also, especially in large hospitals, there are many inpatients moving along the hospital corridors while holding drip stands. Therefore, if the wagon 10 accidentally hits an inpatient, it will be very serious, but the wagon user can properly push the wagon 10 to transport the linen supplies 21 before cleaning to the truck so that such a situation does not occur.

[0124] Then, the wagon 10 for carrying linen supply bags containing all the linen supplies 21 to be cleaned, or the linen supply delivery bag repacked before transportation, is loaded onto the truck and transported to the linen supply cleaning factory. After that, the loaded wagon 10 for carrying linen supply bags or the linen supply delivery bag repacked before transportation is unloaded again at the cleaning factory and carried to the linen supply cleaning inlet in the factory.

[0125] Here, a case will be described where the linen supplies 21 before cleaning are transported to a cleaning factory by truck with the linen supplies 21 before cleaning filled to the brim in the linen supplies storage bag 15 without using a dedicated storage and transportation bag.

[0126] The work procedure in this case is as follows. The linen supplies 21 are taken out of the linen supplies storage bag 15 one by one in the reverse order of the work of storing the linen supplies 21 before cleaning in the linen supplies storage bag 15 described above, and are put into the inlet of the linen supplies cleaning equipment. By continuously repeating the taking out of the linen supplies 21 from the wagon 10 and the putting into the inlet, the amount of the linen supplies 21 stored in the linen supplies storage bag 15 decreases.

[0127] Accordingly, since the weight of the linen supplies storage bag itself acting on the corresponding part 400 of the storage bag bottom support also becomes lighter, contrary to the case where the corresponding part 400 of the storage bag bottom support descends from the upper part to the bottom part of the wagon 10 against the elastic pulling force of the four tension coil springs 510, 520, 530, 540, the corresponding part 400 of the storage bag bottom support rises from the bottom part to the upper part of the wagon 10 by the elastic pulling force of the four tension coil springs 510, 520, 530, 540 (see the change in the amount of linen supplies loaded on the wagon from FIG. 13 to FIG. 15).

[0128] In this way, the corresponding part 400 of the storage bag bottom support of the wagon 10 balances the pulling force with the tension coil springs according to the amount (weight) of the linen supplies 21 before cleaning stored in the linen supplies storage bag 15 and not taken out, and its position rises from the bottom part to the upper part of the wagon 10.

[0129] Therefore, even when taking out the linen supplies 21 before cleaning stored in the linen supplies storage bag 15 from the storage bag, the part where the linen supplies 21 are taken out is always positioned at the same height as the opening of the linen supplies storage bag 15 which is substantially the same as the upper surface opening of the wagon 10.

[0130] As a result, the body posture and orientation of the wagon user when taking out the linen supplies 21 before cleaning from the linen supplies storage bag 15 can always be kept constant, and there is no need to stretch the hand into the back of the bag unnecessarily and take an awkward body posture. The operation of taking out the linen supplies 21 can be carried out efficiently, and it is possible to avoid being troubled by the occurrence of low back pain, stiff shoulders, etc. caused by the physical burden of an awkward posture. This can be easily understood by looking at the changes in the loading amount of the linen supplies 21 on the wagon from FIG. 13 to FIG. 15 in order.

[0131] Subsequently, for the linen supplies 22 after cleaning that have been washed and dried by the cleaning equipment of the linen supplies cleaning factory, passed through the processes of removing dirt and wrinkles by a roll ironer, and neatly folded by the folding equipment, they are either directly loaded onto the linen supplies storage bag transport wagon 10 again, or packed into a dedicated linen supplies delivery transport bag, and then transported in bulk to the hotel, inn, hospital with hospitalization facilities, etc. at the delivery source by truck.

[0132] At this time, when transporting these by loading the entire wagon onto the truck and delivering them to the original place, before transporting by truck, it is naturally necessary to perform the operation of storing the linen supplies 22 after cleaning back into the linen supplies storage bag transport wagon 10 again.

[0133] Also, the same applies when loading the dedicated linen supplies delivery transport bag onto the truck, unloading all the delivery transport bags at the delivery destination, taking out all the cleaned linen supplies 22 packed in them, and repacking them into the linen supplies storage and transport wagon 10.

[0134] The method of storing the linen supplies 22 after cleaning in the linen supplies storage bag 15 in the cleaning factory in this case will be described below. As a specific storage operation, the linen supplies storage bag transport wagon 10 with the linen supplies storage bag 15 emptied is moved to the product take-out section after linen supplies cleaning in the cleaning equipment and waits.

[0135] Then, the neatly folded clean linen articles 22 after cleaning, which come out one after another from the product take-out section, are now put into the linen article storage bag 15 of the wagon 10 for transporting linen article storage bags. The storage of the cleaned linen articles 22 into the linen article storage bag 15 of the wagon 10 for transporting linen article storage bags is basically equivalent to the process of collecting the linen articles 21 before cleaning described above and successively putting them into the linen article storage bag 15 of the wagon 10 for transporting linen article storage bags. Therefore, the description of the procedure for storing the linen articles 21 before cleaning into the linen article storage bag 15 described above is omitted.

[0136] Thus, after finishing the cleaning of the linen articles 21 with the factory facilities, after neatly folding the cleaned linen articles 22 and delivering the entire wagon 10 for transporting linen article storage bags to the destination, the cleaned linen articles 22 that have been neatly folded in the reverse procedure of the procedure shown in FIGS. 10 to 12 are successively taken out from the wagon 10 for transporting linen article storage bags.

[0137] Here, the specific function of storing the cleaned linen articles 22 into the linen article storage bag 15 of the wagon 10 for transporting linen article storage bags according to the present invention will be described. Specifically, as described above, the equivalent part 400 corresponding to the bottom surface support of the storage bag has a specific configuration in which it descends as the amount (weight) of the linen articles 22 stored in the storage bag increases. Therefore, when storing the cleaned linen articles 22 into the storage bag, the height of the equivalent part 400 corresponding to the bottom surface support of the storage bag itself descends as the cleaned linen articles 22 are stored, and the bottom surface of the linen article storage bag 15 also descends accordingly.

[0138] However, since the already stored cleaned linen articles 22 are loaded in the linen article storage bag 15, the position (height) for further storing the linen articles 22 into the linen article storage bag 15 is roughly consistent with the height of the upper opening of the storage bag.

[0139] Thus, similar to the operation of accommodating the linen supplies 21 before cleaning into the storage bag 15, the posture and orientation of the body of the wagon user when accommodating the linen supplies 22 after cleaning into the linen supplies storage bag 15 can always be kept constant, and there is no need to stretch the hand unnecessarily deep into the bag and assume an awkward body posture during accommodation. As a result, the accommodation operation of the linen supplies 22 after cleaning can be performed efficiently, and it is possible to avoid being troubled by the occurrence of low back pain, stiff shoulders, etc. caused by the physical burden due to the awkward posture.

[0140] Also, after all the linen supplies 22 after cleaning are taken out from the wagon 10 for transporting the linen supplies storage bag, the wagon 10 for transporting the linen supplies storage bag can be folded in the reverse procedure from the folded state to the unfolded state as described above, and stored in a dedicated storage space for the wagon 10 for transporting the linen supplies storage bag.

[0141] By such operations, in large-scale hotels, inns, and large hospitals with inpatient facilities, the number of wagons 10 for transporting the linen supplies storage bag becomes extremely large, but these wagons 10 can be stored as many as possible in a limited narrow storage space.

[0142] Subsequently, a modified example of the wagon 10 for transporting the linen supplies storage bag according to the present embodiment will be described. This modified example is the same as the wagon 10 for transporting the linen supplies storage bag according to the above-described present embodiment in terms of the basic configuration, but has differences in configuration and specific operational effects based thereon in the following points.

[0143] FIG. 16 is a perspective view showing a state in which a linen supplies storage bag made of a sturdy net is attached to the wagon according to the present invention, and a small amount of the linen supplies before cleaning is collected in the first process of collecting the linen supplies.

[0144] Also, FIG. 17 is a perspective view showing a state in which a linen supplies made of a sturdy net is attached to the wagon according to the present invention, and the linen supplies before cleaning are collected up to the middle in the process of collecting the linen supplies before cleaning.

[0145] Further, FIG. 18 is a perspective view showing a state in which a linen article storage bag made of a sturdy net is attached to a wagon according to the present invention, and as many linen articles as possible before cleaning are collected in the process of collecting the linen articles before cleaning.

[0146] Further, FIG. 19 is an end view partially transparently showing a state in which a folded linen article after cleaning is stored in a linen article storage bag made of a sturdy net attached to a wagon according to the present invention until the bottom pressing portion of the linen article storage bag reaches a lower height. For is located at the lower height.

[0147] Further, FIG. 20 is a view corresponding to FIG. 19 showing a state in which an operator transfers about one-third of these linen articles from the upper side of the wagon to a transport bag for loading on a truck or the like in order to load the linen articles after cleaning. For is an end view partially transparently showing a state in which the bottom pressing portion of the linen article storage bag has risen to a middle height. For has risen to the middle height.

[0148] Further, FIG. 21 is a view corresponding to FIG. 20 showing a state in which an operator transfers the remaining two-thirds of these linen articles from the upper side of the wagon to a transport bag for loading on a truck or the like in order to load the linen articles after cleaning. For is an end view partially transparently showing a state in which the bottom pressing portion of the linen article storage bag has risen to the highest height. For has risen to the highest height.

[0149] The elastic suspension member 500 of the wagon 10 for transporting the linen article storage bag according to this modification (hereinafter simply referred to as "modification" as appropriate) is composed of tension coil springs 510, 520, 530, 540 as described above, but is different from the above-described embodiment in that each has a coil spring cover 550. And the tension coil springs 510, 520, 530, 540 themselves are covered by the coil spring cover 550.

[0150] When the coil spring cover 550 is used to take in and out the linen articles in the linen article storage bag when using the wagon 10 for transporting the linen article storage bag, when the corresponding part 400 of the bottom surface support plate of the linen article storage bag rises and falls inside the wagon 10 for transporting the linen article storage bag, the linen article storage bag is prevented from being pinched and damaged by the slight gap caused by the expansion and contraction of the coil spring, or a part of the net of the linen article storage bag, which is entirely composed of a net-shaped bag body, is caught or pinched and damaged.

[0151] The process leading to the introduction of the above modification example and the effects peculiar to this modification example will be described below. The linen articles 21 and 22 are not limited to the sheets and pillowcases used in hotels, inns, and hospitals with inpatient facilities as described above.

[0152] Specifically, in recent years, stores such as esthetic salons, massage salons, and hot yoga have been spreading. In such stores, a large amount of oil such as massage oil is used, so that such oil remains soaked into the linen articles 21 after use. When collecting such used linen articles 21, the used linen articles 21 before cleaning are forcibly stuffed into the linen article storage bag 15, and the wagon 10 equipped with this linen article storage bag 15 is transported to a linen article cleaning factory by truck for cleaning.

[0153] However, since such used linen articles 21 soaked with a large amount of oil are forcibly stuffed into a normal linen article storage bag 15, they are already in a compressed state and have stored a certain amount of heat in the bag. Then, even when the linen articles 21 soaked with oil that have been forcibly stuffed into such a storage bag and are in a heat storage state are repacked into a truck loading and transporting bag when being transported to a linen article cleaning factory, these oil-soaked linen articles 21 will be further compressed. And when a large amount of them are stuffed into the truck bed together with the wagon and transported to a linen article cleaning factory, for example, under the scorching sun in midsummer, serious problems may occur.

[0154] Specifically, without an air conditioning facility, the heat transferred from the outside atmosphere and the radiant heat caused by direct sunlight continuously hitting the outer plate of the truck bed cause the temperature in the truck's cargo compartment to rise extremely. And since the linen supplies 21 containing oil packed in the linen supplies storage bag 15 are transported in a highly compressed state, various factors such as the heat stored inside and the frictional heat generated by the rubbing of the linen supplies against each other due to vibrations during transportation are intertwined, leading to an ignition phenomenon, which may spread to the oil content of the linen supplies 21 and result in a vehicle fire.

[0155] Such a phenomenon may also occur when repacking into a truck-loading transport bag instead of loading the entire wagon onto the truck, as the oil-soaked linen supplies 21 will be more compressed.

[0156] Also, even if the truck arrives at the linen supplies cleaning factory without an ignition phenomenon occurring inside such a transport vehicle, the linen supplies 21 containing oil packed inside the linen supplies storage bag are in a state of having stored a considerable amount of heat. When the linen supplies 21 in this state are put into the washing inlet of the cleaning factory and the cleaning process begins, they may become even hotter and cause an ignition phenomenon, which may lead to a fire in the cleaning equipment.

[0157] To prevent such serious accidents, in the process before transporting to the linen supplies cleaning factory after collecting the used linen supplies containing oil as described above and repacking them into a truck-loading transport bag, at the stage of collecting the oil-containing linen supplies 21 with a wagon, instead of the normal linen supplies storage bag 15, a linen supplies storage bag 16 made of a net with sufficient strength such as a golf net is used to efficiently dissipate heat from the linen supplies 21 packed in the linen supplies storage bag 16 to the surrounding area.

[0158] However, when the linen article storage bag 16 made of such a net with sufficient strength is attached to the wagon 10, as the corresponding portion 400 of the storage bag bottom support moves up and down when the linen articles 21 are taken in and out of the linen article storage bag 16, the gaps of the tension coil springs 510, 520, 530, 540 that suspend this move open and closed, and in this process, a part of the net may be pinched by the tension coil springs 510, 520, 530, 540.

[0159] As a result, the possibility increases that a part of the linen article storage bag 16 made of a net (net material) is damaged or a part of the net remains cut. If such a state is left unattended, the damaged part of the linen article storage bag 16 will become larger, and for example, when small linen articles such as pillow covers are stored in the storage bag, they may fall off from this damaged part and disappear.

[0160] In addition, the user of the wagon 10 may notice that a part of the net is pinched by the tension coil springs 510, 520, 530, 540 in the process of the gaps of the tension coil springs 510, 520, 530, 540 opening and closing. In such a case, if one tries to correct the pinching of this net material, not only will it be very troublesome, but there is also a risk of accidentally pinching a fingertip by the tension coil springs 510, 520, 530, 540 and suffering an unexpected injury.

[0161] However, by attaching a coil spring cover 550 that individually and entirely covers each of the tension coil springs 510, 520, 530, 540 (500) as in the modification of this embodiment to each of the tension coil springs 510, 520, 530, 540, it becomes possible to reliably prevent the above-mentioned problems and unexpected injuries to the wagon user.

[0162] Finally, the extremely excellent features of the present invention will be described below. The corresponding portion 400 of the storage bag bottom support that can be raised and lowered by the elastic force of the tension coil spring 500, which is one of the components of the present invention, is made of a pipe member having excellent strength and durability, such as a rectangular aluminum alloy as shown in the drawing.

[0163] When storing linen items in the wagon, the pipe members are bent into a chevron shape by hinges 450 attached to the lower surfaces of the mating portions of the pipe members, and when the wagon is in use, the storage bag bottom support equivalent portion 400 is formed by a tension coil spring 180 provided on the same lower side as the above-described hinge 450. The side surfaces of the rectangular pipe members of the two component half portions 410 and 420 that face each other are in close contact with each other as a whole.

[0164] With such a configuration, even if the weight of the linen item storage bags 15 and 16, which are very heavy, for example, linen items before cleaning and filled with contents, acts directly, the angle between the component half portions 410 and 420 of the storage bag bottom support equivalent portion 400 does not bend into a V shape when viewed from the side. That is, the mating surfaces of the respective bag bottom support component half portions 410 and 420 do not bend and deform toward the downstream side with respect to both ends in the width direction. This is similar to the so-called wedge effect, and its action effect can be easily understood structurally.

[0165] In particular, bath towels used in a shower-equipped bathroom provided in each guest room of a hotel, etc. are all wet. When these are packed together in the linen item storage bag 15, the total weight of the linen item storage bag 15 increases considerably, and a considerable load is applied to the storage bag bottom support equivalent portion 400 that supports the bottom of the linen item storage bag 15. However, since the storage bag bottom support equivalent portion 400 has the above-described structure, it will not be damaged even when such a load is applied.

[0166] In addition to this, since the storage bag bottom support equivalent portion 400 itself is formed of a rectangular pipe frame with a rectangular cross-section, the overall weight of this portion is light, and the vertical lifting and lowering operations can be smoothly performed without difficulty by coil springs connected to the four corners of the upper part of the wagon.

[0167] Furthermore, when the frame halves of the angular pipes that constitute the portion corresponding to the bottom surface support of the storage bag 400 form a mountain shape when the wagon is being stored, a coil spring cover 550 made of a vinyl sheet 490 or the like is formed so as to cover from above the V-groove space formed in the longitudinal direction of the two opposed angular pipes due to this mountain shape. Therefore, when changing the wagon 10 from the folded state to the usable state with the linen storage bag 15 attached to the wagon 10 all the time, when sandwiching the bottom of the linen storage bag 15 in this gap portion 490 and damaging this portion, and when the linen articles 21 are filled to the brim, it is possible to avoid the damaged and weakened portion being torn and the linen storage bag 15 becoming unusable all of a sudden during the collection of the linen articles.

[0168] Particularly, as described above, when the linen storage bag 16 is formed in a net shape (mesh shape), if the V-groove-shaped space as described above is formed, when making the wagon 10 into a usable state, a part of the net may be easily sandwiched, and in particular, the present invention can surely prevent the linen storage bag 16 formed in a net shape (mesh shape) with a high price from being rendered unusable in an instant.

[0169] Also, the portion corresponding to the wagon bottom plate of the wagon itself 100 has the same basic configuration as the portion corresponding to the bottom surface support of the storage bag described above, and a space closing cover 190 made of a vinyl sheet or the like is formed so as to cover from above the V-groove space formed in the longitudinal direction of the two angular pipes. Therefore, it is possible to prevent a user of the wagon 10 from accidentally getting injured by pinching a part of the palm or a finger by pressing this portion with the palm when assembling the wagon 10.

[0170] In addition, regarding the foldable side connection part that can expand and contract in the width direction of the wagon 10, it is formed in a pantograph shape, that is, in a state where an X shape formed by the intersection of two links is further arranged in parallel and four links are partially overlapped so as to be rotatable relative to each other. In addition, a relatively large disk-shaped spacer 390 for preventing pinching is sandwiched between the overlapping portions of the respective links that rotate and slide relative to each other.

[0171] By having such a configuration, the present invention prevents the parts of the linen article storage bag 16 made of the cloth described above or the parts of the linen article storage bag 16 made of a net-like (mesh-like) member from being sandwiched between the rotational sliding parts of each link and being damaged.

[0172] From the description in the text of the above embodiment of the present invention and the specific configurations shown in the drawings, it can be seen that various problems shown in the column of the problems to be solved in the prior art based on the present invention are solved all at once. That is, the special usefulness unique to the present invention can be understood from the above description in the text and the drawings.

[0173] Note that the present invention is not limited to the specific examples of the embodiments shown in the above text and drawings, and various members can be used within the range where the functions and effects of the present invention can be exerted. For example, a pipe member corresponding to the wagon side plate part 200 standing upright with the wagon 10 in a fixed state may be substituted with something like a honeycomb plate having excellent strength and durability.

[0174] The two bottom plate configuration halves 210 and 220 constituting the wagon bottom plate equivalent part 100 and the two bag bottom support configuration halves constituting the linen article storage bag bottom equivalent part may also be substituted with something like a honeycomb plate material having similar excellent strength and durability. Also, instead of the coil spring in the above embodiment, a stretchable rubber-like member having sufficient durability may be used.

[0175] Also, for the linen For article storage bags 15 and 16 carried by the linen article storage bag carrying wagon 10, as long as they can exert the functions and effects of the present invention, they are not limited to the linen articles before or after cleaning as described above, and various other things can be stored and carried in this storage bag.

[0176] More specifically, in the above-described embodiment, as the specific contents to be packed in the supply storage bag 15 provided in the supply storage bag transport wagon 10, linen supplies widely and routinely used in accommodation facilities such as hotels and inns and hospitals were introduced. However, in addition to these, as an example of supplies, for example, cushions, blankets, comforters, pajamas, bathrobes, and slippers, which are personal belongings accidentally forgotten by hotel or inn guests, can be wrapped in vinyl with the room number written on it and then successively stored in the supply storage bag.

[0177] In this case, since it is not considered that there are extremely many forgotten items, it is possible to use only one supply storage bag transport wagon 10 to collect, organize, and store the forgotten items of guests in accommodation facilities such as hotels and inns on a fairly large scale. From this perspective, the present invention is not limited to the linen supply storage bag transport wagon 10, and it is possible to effectively utilize it as a general supply storage bag transport wagon 10 excluding linen supplies in the above-described facilities.

[0178] In addition to the above, as a specific form of the supply storage bag transport wagon according to the present invention, the supply storage bag attached to the linen supply storage bag transport wagon is composed of a linen supply storage bag, and is excellent in terms of usability because it is composed of an outer bag with a low replacement frequency and an inner bag with a high replacement frequency that is cleaned each time it is replaced. More specifically, the inner bag can be mounted in a state of being entirely overlapped along the inner surface inside the outer bag, and engaging hooks that are detachably engaged with the engaging portions provided at the four upper corners of the linen supply storage bag transport wagon are provided at predetermined positions of the opening of the outer bag. If the configuration is such that the inner bag is removed from the outer bag each time the linen supply storage and transport wagon is used, only this inner bag is cleaned, and the cleaned inner bag is attached to the outer bag again, it is extremely excellent in terms of actual usability.

[0179] Further, as a specific form of the wagon for transporting a supply storage bag according to the present invention, a method for manufacturing a wagon for transporting a linen supply storage bag is, in the wagon for transporting a supply storage bag according to claim 1, the linen supply storage bag is composed of a net-like net bag, and engaging hooks that can be detachably engaged with engaging portions provided at the upper four corners of the wagon for transporting linen supplies are respectively provided at positions where they can be respectively engaged with the engaging portions. By having a configuration in which the net bag is provided at the upper opening of the net bag, the net bag can be firmly attached to the wagon for transporting the linen supply storage bag at an appropriate position, and when packing or removing linen supplies from the storage bag, a part of the net of the storage bag will not catch on the linen supplies, and it can be made very excellent in terms of actual usability.
