Description

  The present invention relates to a folding structure for a travel bag.

Conventionally, travel bags, excluding hard suitcases, especially large-sized travel bags made of synthetic fabrics such as nylon and polyester, have been widely used because they are lightweight and durable, and the structure has a storage room. The bag body and lid are formed so that they can be opened and closed with a zipper, and two types are attached: a hand for lifting the bag on the surface in the longitudinal direction of the bag, and a traction handle for pulling the bag when moving A caster for movement is attached to one side or four corners of the bottom surface of the bag body. When a moving caster is attached only to one side (towing direction) of the bag, a pair of support legs are provided on the bottom surface on the side opposite to the caster in order to keep the level when the travel bag is raised.

Although the large-sized travel bag is lightweight, it is bulky and is often troubled by a storage place when not in use. On the other hand, a carry-back type small travel bag is known that has a structure in which the bottom surface is folded and folded in order to be folded and stored compactly (for example, Patent Documents 1 and 2).

The former carry-back travel bag is formed so that the frame with the back body and casters attached is formed separately, and the auxiliary frame attached to the lower frame making up the frame is detachably attached so that the bottom area can be reduced. It is. Further, a hard bottom plate is rotatably attached to the entire inner bottom surface of the bag body. Therefore, when folding a travel bag, first peel off the bottom of the bag body from the lower frame, separate the auxiliary frame from the lower frame, and then raise the bottom plate on the inner bottom of the bag body before folding the bag body. The structure is complicated and the folding work is troublesome. In addition, there are many problems such as the possibility of losing the removed parts.

The latter is not a travel bag, but a shopping cart used for everyday shopping. A receiving frame that is pivotally attached to the base of the vertical frame in a direction perpendicular to the base and a shopping bag placed on the receiving frame. The shopping cart receiving frame is pivoted in the vertical frame direction when not in use, and then the bag is folded and attached to the shopping cart to make it compact. The shopping cart and shopping bag are separated. However, the shopping cart has a complicated structure.

Therefore, the problem to be solved by the present invention is that when storing a travel bag, particularly a large travel bag formed of a flexible material such as synthetic fiber cloth or flexible synthetic leather, it will be bulky if stored in its original shape. May be in trouble. Furthermore, when carrying a large travel bag that has been emptied at the destination, it is inconvenient to carry because it is still bulky in its original shape. Therefore, the purpose of the present invention is to make it possible to fold a large-sized travel bag with a simple structure and store it in a small size when not in use, or to carry a travel bag in a compact manner for convenient carrying.

In the present invention, an extendable tow handle 11 for towing a bag is attached to the center of the back surface, a hand 15 for carrying the bag is provided at the upper end of the center, and a plurality of casters 16 for moving the bag are attached to the bottom surface. In a travel bag 1 made of synthetic fiber fabric or flexible synthetic leather, in which a lid plate 19 provided at the opening of the bag main body 2 having the storage chamber 3 is attached with a fastener 20 so as to be opened and closed, the bag main body 2 A folding mechanism 31 that folds the bottom surface portion 4 of the bag body 2 is attached to the inner bottom substrate 5b. The bag body 2 has a vertical substrate 5a of a substrate 5 formed of a synthetic resin material having flexibility positioned on the back side, an inner bottom substrate 5b integrally positioned on the inner bottom surface, and the inner bottom substrate. The fixed surface 5c and a bent curved surface 5d whose front end half bends upward are formed, and the distance between the upper surface of the fixed surface 5c and the upper surface of the bent curved surface 5d is fixed between the fixed plate 7 and the movable plate 8, respectively. An interval X is provided in which the fixed plate 7 on the fixed surface 5c and the movable plate 8 on the folded curved surface 5d do not come into contact with each other when bent to the right. Further, the folding mechanism 31A has an insole cloth 32A formed of a synthetic fiber cloth laid on the entire inner bottom surface or the central portion of the bag body 2, and a gap X provided between the fixed plate 7 and the movable plate 8. The engaging member 33 to be fitted and the surface fasteners 35 and 36 which are detachably bonded to the upper surfaces of the fixed plate 7 and the movable plate 8 are attached to the lower surface of the insole cloth 32A. The bottom surface portion 4 of the bag main body 2 is formed by fitting the surface fasteners 35 and 36 to the surfaces of the fixed plate 7 and the movable plate 8 by fitting into the gap X, and the leading end side of the insole fabric 32 is directed upward. When the folding surface 5d is folded upward after rolling up and the locking member 33 is removed from the gap X, the fixed plate 7 and the movable plate 8 are bent without contacting each other, so that the bottom surface portion 4 can be folded. It is characterized by that. Furthermore, the folding mechanism 31C sews a storage bag 34 formed of a synthetic fiber fabric at a predetermined position on the back surface of the insole fabric 32A or the insole fabric 32B, and the clearance bag X is inserted into the storage bag. A hook and loop fastener 35 and 36, which respectively accommodates the engaging piece 33 to be fitted, and is detachably bonded to the upper surfaces of the fixed plate 7 and the movable plate 8, are attached. The folding mechanism 31D has a rigid reinforcing plate 40 attached to the back surface of the insole cloth 32A or the insole cloth 32B, and the locking member 33, the fixed plate 7 and the movable plate 33 are movable on the lower surface of the reinforcing plate. Surface fasteners 35 and 36 that are detachably bonded to the upper surface of the plate 8 are respectively attached. Further, the folding mechanism 31E attaches a locking member 42 and hook-and-loop fasteners 35 and 36 to the back surface of the insole cloth 32A or the insole cloth 32B, respectively, and the locking member 42 is a symmetrical position of both wall surfaces in the short direction. The locking projections 43, 43 are provided on the inner bottom substrate 5b so that they can be fitted to the fitting recesses 47, 48 provided at positions facing the inner wall surface of the gap X between the fixed plate 45 and the movable plate 46 attached to the inner bottom substrate 5b. At the same time as inserting the locking member 42 into the gap X, the fitting recesses 47 and 48 and the locking projections 43 and 43 are fitted, and the surface fasteners 35 and 36 are mounted on the upper surfaces of the fixed plate 45 and the movable plate 46. It is provided so that it can be bonded. Furthermore, the travel bag 1 includes a pair of fastening belts 22a and 22b each having a pair of male and female connecting portions 24a and 26a attached to the tips of a long belt 23a and a short belt 25a having different lengths. When the bag is used as a travel bag, the male and female connecting portions 24a and 26a of the long and short belts 23a and 25a on the same side surface of the bag body 2 are detachably connected to each other. When the bottom area is folded in half by the operation of the folding mechanisms 31A, 31C, 31D, 31E attached to the inner bottom surface of the bag body 2, the long belts 23a, 23b respectively attached to both side surfaces of the bag body 2 The male and female connection parts 24a and 26b are detachably connected and tightened at the approximate center of the body part.

Therefore, the fixed plate 7 and the movable plate 8 are fixed in parallel by providing a fixed gap X between the fixed surface 5c formed on the inner bottom substrate 5b of the bag body 2 and the upper surface of the folding surface 5d, respectively. The bottom surface portion 4 can be formed by interposing the locking member 33 of the folding mechanism 31 attached to the upper surface in the gap X to prevent the folding surface 5d from bending upward. Further, when the insole cloth 32 is raised upward to disengage the locking member 33 from the gap X and the folding surface 5d of the inner bottom substrate 5b is bent upward, the movable plate 8 attached to the surface of the folding surface 5d is fixed. Since it can be smoothly folded without hitting 7 and the bottom area of the travel bag 1 can be reduced to about half and the vertical width can be reduced, a narrow storage space can be obtained. Further, the upper surfaces of the fixed plate 7 and the movable plate 8 are bonded and fixed by the hook-and-loop fasteners 35 and 36 provided on the back surface of the insole fabric 32, so that the locking member 33 is spaced by the vibration or impact caused by the movement of the travel bag 1. The separation from X can be prevented. Further, the locking protrusion 43 provided on the wall surface in the short direction of the locking member 42 constituting the folding mechanism 31E and the locking recesses 47 and 48 provided on the side surfaces of the fixed plate 45 and the movable plate 46 are fitted. By being stabilized, it is possible to prevent the locking member 42 from being separated from the gap X due to vibration or strong impact during movement, and the shape of the bottom surface portion 4 is lost. Furthermore, since the travel bag 1 is entirely formed of a synthetic fiber fabric and does not have a fixed shape, the travel bag 1 is formed by attaching a plurality of fastening belts 22a and 22b to the outer wall surface of the bag body 2. When used, the bag body 2 is kept in a fixed shape. When the travel bag 1 is stored, the bag body 2 is prevented from spreading by fastening the body with fastening belts 22a and 22b. And compactness can be maintained together.

The embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a travel bag according to the present invention, and FIG. 2 is a diagram showing a state where a body portion of a travel bag with a bent bottom is fastened with a fastening belt. 3 is an enlarged perspective view of a main part of the folding mechanism A, and FIG. 4 is an enlarged cross-sectional view of the main part of the folding mechanism A. The travel bag 1 is formed of a synthetic fiber fabric such as nylon or polyester or a synthetic leather having flexibility, and a retractable traction handle 11 is attached to the back center of the bag body 2 to carry the bag at the center upper end. A hand 15 is provided, a plurality of casters 16 for moving the bag are respectively attached to the bottom surface, and a lid plate 19 is attached to the opening provided in the housing chamber 3 of the bag body 2 so as to be opened and closed with a fastener 20. Further, when the caster 16 attached to the bottom surface portion is attached only to the back surface side of the bottom surface portion, a support leg portion 18 for supporting the bag body 2 is attached to the opposite side of the bottom surface portion.

Since the travel bag 1 is entirely formed of a synthetic fiber fabric and does not have a fixed shape, a plurality of fastening belts 22 a and 22 b are attached in the longitudinal direction of both outer sides of the bag body 2. As shown in FIG. 2, the fastening belts 22a and 22b have a long belt 23a and a short belt 25a having different lengths positioned on the same outer surface of the bag body 2, and a pair of male and female connecting portions at the leading ends of the long and short belts. 24a and 26a are respectively attached to form a fastening belt 22a, and a pair of fastening belts 22a and 22b are respectively attached to the outer side surfaces of the bag body 2 at symmetrical positions.

When the long belt 23a and the short belt 25a are attached to the same side of the bag body 2 as a travel bag, the long belt 23a and the short belt 25a are respectively attached to opposite positions on the same side. Are attached so that the long belts 23a, 23b attached to both side faces face each other.

Therefore, when used as the travel bag 1, the long and short belts 23a, 25a and 23b, 25b on the same side are connected to each other to maintain the regularity of the bag body 2 and prevent the travel bag 1 from being distorted. it can. The bag 1 is folded upward by the folding mechanism 31 and the bag body 2 and the lid plate 19 are folded. Then, the connecting portions 24a and 26b of the long belts 23a and 23b on both sides are connected at the approximate center of the trunk. By fastening, the bag body 2 and the cover plate 19 can be prevented from spreading, and the formability can be maintained in a compact manner.

As shown in FIG. 3, the substrate 5 attached to the back side and the bottom side in the bag body 2 is formed by integrating a vertical substrate 5 a on the back side and an inner bottom substrate 5 b on the bottom side by using a synthetic resin material having flexibility. The fixed substrate 5b is formed with a fixed surface 5c that maintains the original shape and a curved surface 5d that is bent upward at the tip half, and the bag body 2 is formed on the upper surface of the fixed surface 5c and the curved surface 5d. A flat fixed plate 7 and a movable plate 8 forming the inner bottom surface of each are fixed.

The fixed plate 7 and the movable plate 8 are spaced so that the movable plate 8 attached to the upper surface of the folded curved surface 5d and the fixed plate 7 attached on the fixed surface 5c do not contact each other when the folded curved surface 5d is bent upward. X is attached. Therefore, the folding surface 5d of the inner substrate 5b can be smoothly bent.

The pulling handle 11 has a lower end of a telescopic rod 11 having a handle at the upper end attached to a support substrate 13 positioned at the center of the lower end of the substrate 5, and a bottom portion 4 of the bag body 2 on a horizontal portion 13a of the support substrate. A folding mechanism 31 is attached to be able to be bent. Reference numeral 17 denotes holders attached on both sides of the support substrate 13 and accommodates a caster 16 for pulling and moving the travel bag 1.

A folding mechanism 31A shown in FIGS. 3 and 4 is provided between an insole fabric 32A formed of a synthetic fiber fabric such as nylon or polyester, and a fixed plate 7 and a movable plate 8 provided on the upper surface of the inner bottom substrate 5b. A locking member 33 detachably fitted in the provided gap X, and hook and loop fasteners 35 and 36 for removably bonding the insole cloth 32 to the upper surfaces of the fixed plate 7 and the movable plate 8, respectively. One end of an insole fabric 32A is attached to a horizontal portion 13a of the support substrate 13 provided at the center of the back side of the bag body with a fastener 27 such as a screw or a scissors.

The insole fabric 32A has a lateral width that is the same as the lateral width of the fixed plate 7, and a vertical width that is substantially square up to the tip in the short direction of the movable plate 8, and the fixed plate in the width direction of the back surface. 7 is attached to the gap X provided between the movable plate 8 and the movable plate 8, and is attached to the back surface of the insole cloth 32A at a position matching the surfaces of the fixed plate 7 and the movable plate 8. Removable hook-and-loop fasteners 35 and 36 are attached and formed. By attaching the hook-and-loop fasteners 35 and 36 to the back surface of the insole cloth 32A, it is possible to prevent the locking piece 33 fitted in the gap X from coming out of the gap X due to vibration or impact caused by the movement of the travel bag 1. In addition, by placing the insole fabric 32A on the inner bottom surface, it can also be used as a bag insole.

The folding mechanism 31 </ b> B shown in FIG. 5 can also form the fixing plate 7 and the insole fabric 32 </ b> A so as to be approximately the same as the inner bottom surface of the bag body 2. By laying on the entire inner bottom surface of the bag main body 2, the strength and appearance of the inner bottom surface can be improved, and small items accommodated in the bag main body 2 can be removed from the gap between the inner bottom surface and the insole cloth 32B. It can be prevented from being dropped and lost.

The folding mechanism 31C shown in FIGS. 6 and 7 has a cloth containing bag 34 sewn at a predetermined position on the back surface of the insole cloth 32A or the insole cloth 32B, and the engaging piece 33 is inserted into the containing bag. Can be prevented from falling off from the back surface of the insole cloth 32A or the insole cloth 32B. Further, the process of sewing the accommodation bag 34 to the insole cloth 32A, 32B can be easily formed because it is the same cloth, and is easier than attaching the locking piece 33 directly to the insole cloth 32A, 32B. It is convenient because it is hard to come off.

The folding mechanism 31D shown in FIG. 8 is formed by adhering a rigid reinforcing plate 40 to the back surface of the insole fabric 32A or the insole fabric 32B, and adhering the locking piece 33 to the back surface of the reinforcing plate. It is firmly formed with screws or rivets, and detachable hook-and-loop fasteners 35 and 36 are attached to positions that match the fixed plate 7 and the movable plate 8, respectively. Therefore, it is possible to prevent the locking piece 33 of the folding mechanism 31 from being peeled off from the insole cloth 32 due to vibrations or shocks caused by the movement of the travel bag 1.

The reinforcing plate 40 can be reduced in weight by being formed of a synthetic resin plate or a cardboard board impregnated with a synthetic resin agent, or a plywood material such as a veneer board. Further, by attaching the reinforcing plate 40 to the back surface of the insole fabric 32, the inner bottom surface can be prevented from being deformed by vibrations or strong impacts caused by the movement of the travel bag 1 and stabilized.

The folding mechanism 31E shown in FIGS. 9 and 10 is provided with locking projections 43 and 43 at the wall surface symmetrical positions in the short direction of the locking piece 42 attached to the back surface of the insole cloth 32A or the insole cloth 32B, On the wall surface facing the gap X side between the fixed plate 45 and the movable plate 46 attached to the inner bottom substrate 5b, fitting concave portions 48 and 49 are provided at positions matching the locking projections 43 and 43, respectively.

A hook-and-loop fastener 35 attached to a predetermined position on the back surface of the insole cloth, with the locking protrusion 43 of the locking piece 42 matched with the fitting recesses 48 and 49 provided in the fixed plate 45 and the movable plate 46, In 36, the surfaces of the fixed plate 45 and the movable plate 46 are bonded. Therefore, the force applied to the movable plate 46 in the downward direction by the weight of the baggage accommodated in the travel bag 1 acts to press the fitting recesses 48 and 49 and the locking projections 43 and 43 into closer contact with each other. It is possible to prevent the locking piece 42 from dropping from the gap X due to strong vibrations or impacts received during movement or on stairs such as at stations or airports.

Hereinafter, the operation of the embodiment of the travel bag according to the present invention will be described. When the travel bag 1 is used, as shown in FIGS. 3 and 4, the fixed plate 7 and the movable plate 8 located on the inner bottom surface of the bag body 2. Is fitted horizontally to the gap X between the fixed plate and the movable plate, and the engaging piece 33 attached to the insole fabric 32 of the folding mechanism 31A is fitted to the back of the insole fabric 32. By fixing the surface fasteners 35 and 36 to the surfaces of the fixed plate 7 and the movable plate 8 respectively, the bottom surface portion 4 can be formed by fixing the inner bottom substrate 5b in the horizontal direction.

Since the travel bag 1 is formed so that the front end side (folded curved surface 5d) of the fixed substrate 5b bends smoothly, the engagement piece 33 is not interposed in the gap X between the fixed plate 7 and the movable plate 8, Since the tip side is bent by its own weight, the bottom part of the travel bag 1 cannot be stabilized. Therefore, by interposing the latching piece 33 in the gap X provided between the fixed plate 7 and the movable plate 8, the side surface of the movable plate 8 and the side surface of the latching piece 33 provided on the upper surface of the folding surface 5d. It is possible to maintain the horizontal state of the entire bottom surface portion 4 by abutting and preventing upward bending.

Further, by attaching and fixing surface fasteners 35 and 36 attached to the back surface of the insole cloth 32 to the surfaces of the fixed plate 7 and the movable plate 8, the locking piece is caused by vibration or impact during movement of the travel bag 1. Can be prevented from detaching from the gap X, and an insole on which the insole fabric itself is laid on the inner bottom surface of the bag body 2 can be formed.

Since the travel bag 1 is entirely formed of a synthetic fiber fabric and does not have a fixed form, when the travel bag 1 is attached to the bag body 2 and used as the travel bag 1, a long and short belt of the same side surface is used. 23a, 25a and 23b, 25b can be connected to each other to maintain the regularity of the bag body 2 and prevent the bag 1 from being distorted (FIG. 1).

When storing the travel bag 1, the bottom part 4 is folded upward by the folding mechanism 31 attached to the bag body 2, the bag body 2 and the cover plate 19 are folded, and then the long belts on both sides in the approximate center of the body part. By connecting and fastening the connecting portions 24a and 26b of 23a and 23b, it is possible to prevent the bag main body 2 and the cover plate 19 from spreading and to keep the formability in a compact manner (FIG. 2).

When the bottom portion 4 of the travel bag 1 is folded and stored, as shown in FIG. 11, the front side (movable plate side) of the insole fabric 32 is raised and the hook-and-loop fastener 36 is peeled off from the upper surface of the movable plate 8. The insole cloth 32 is detached from the inner bottom substrate 5b by removing the latching piece 33 that is raised and fitted in the gap X and then peeling off the surface fastener 35 adhered to the fixing plate 7.

Next, when the front half (folded curved surface 5d) of the inner bottom plate 5b of the bag body 2 is folded upward, the folded curved surface 5d and the movable plate 8 are smoothly folded upward. Since the movable plate 8 and the fixed plate 7 are attached with a gap X so that they do not contact each other, the inner bottom plate 5b and the movable plate 8 can be bent smoothly, so that the bottom area of the travel bag 1 can be halved. (FIG. 12).

Further, after bending the bottom surface portion 4 of the bag body 2 to halve the bottom area, as shown in FIG. 2, the connecting portions of the long belts 23a and 23b of the fastening belts 22a and 22b attached to the outer surface of the bag body 2 24a and 26b are connected to each other at approximately the center of the body part and fastened to prevent the folded travel suitcase 1 from spreading so that it can be stored in a narrow storage space and can also be folded when moving. The travel bag 1 can be carried without spreading. By attaching the fastening belts 22 and 22 to both outer sides of the bag body 2 in advance, it is possible to prevent the fastening belts from being lost. When the travel bag 1 is folded and stored or moved, the bag can be stored or moved not only in the fastening belts 22a and 22b, but also in a bag having a size that allows the folded travel bag 1 to be stored. is there.

By forming the fixing plate 7 and the insole cloth 32B constituting the insole cloth 32B over the entire inner bottom surface of the bag body 2, it can be spread over the entire inner bottom surface as the insole of the bag body 2, and It is possible to prevent a small item or the like housed in the housing chamber from falling from the gap to the inner bottom surface and being lost.

The folding mechanism 31C is locked by sewing a cloth storage bag 34 at a predetermined position on the back surface of the insole cloth 32A or the insole cloth 32B, and inserting and holding the engaging piece 33 into the storage bag. The part 33 can be prevented from falling off. Further, the process of sewing the accommodation bag 34 on the insole fabric 32 can be easily formed because it is the same fabric, and is easier and less difficult to remove than attaching the locking piece 33 directly to the insole fabric 32. Convenient.

The folding mechanism 31D has a bottom surface portion because the travel bag 1 is made of a flexible material, so that the bag body 2 does not have a fixed shape, and the fixed substrate 5b forming the bottom surface portion 4 has flexibility. 4 swings back and forth and is liable to be distorted and unstable. Therefore, by forming the reinforcing plate 40 having hardness on the back surface of the insole fabric 32, it is possible to prevent the bottom surface portion 4 from being shaken or distorted and to be stabilized. Furthermore, since the locking member 33 can be directly fixed by attaching the reinforcing plate 40 having hardness, the locking plate 33 can be locked by strong vibration or impact received during the travel of the travel bag 1 or at the stairs of the station or airport. The member 33 can be attached firmly without fear of falling off the insole fabric 32.

The folding mechanism 31E is provided with a locking projection 43 at a laterally symmetrical position in the short direction of the locking piece 42 attached to the insole cloth 32, and a fixing plate 45 attached to the locking projection and the inner bottom substrate 5b. And the recesses 47 and 48 provided on the side surface of the movable plate 46 are detachably fitted to each other so that the movable plate 46 can be moved downward depending on the weight of the bag body or the weight of the luggage accommodated in the accommodation chamber 3. Because the applied force acts and the locking projection 43 is tightly fitted by the fitting recesses 47 and 48, the locking piece is dropped from the gap X due to a strong impact received at the travel bag or at the station or airport. Can be prevented and the bottom surface portion 4 can be stabilized.

As described above, the folding mechanism 31 is engaged with the insole cloth 32 formed of a synthetic fiber cloth that also serves as an insole for a bag and the gap X provided between the fixed plate 7 and the movable plate 8. It consists of a piece 33 and hook-and-loop fasteners 35 and 36 for fixing the insole cloth 32 to the surfaces of the movable plate and the fixed plate. Since the total number of parts is small, the assembly work can be simplified and the cost can be reduced. It is. In addition, the latching piece 33 can be removed with a single touch of folding up the insole cloth 32, and can be easily folded into a compact size by folding it up. By fixing one barrel portion with the fastening belts 22 and 22, it is convenient to carry and can be stored in a narrow space.

  The present invention relates to a folding structure for a travel bag.

Conventionally, travel bags, excluding hard suitcases, especially large-sized travel bags made of synthetic fabrics such as nylon and polyester, have been widely used because they are lightweight and durable, and the structure has a storage room. The bag body and lid are formed so that they can be opened and closed with a zipper, and two types are attached: a hand for lifting the bag on the surface in the longitudinal direction of the bag, and a traction handle for pulling the bag when moving A caster for movement is attached to one side or four corners of the bottom surface of the bag body. When a moving caster is attached only to one side (towing direction) of the bag, a pair of support legs are provided on the bottom surface on the side opposite to the caster in order to keep the level when the travel bag is raised.

Although the large-sized travel bag is lightweight, it is bulky and is often troubled by a storage place when not in use. On the other hand, a carry-back type small travel bag is known that has a structure in which the bottom surface is folded and folded in order to be folded and stored compactly (for example, Patent Documents 1 and 2).

The former carry-back travel bag is formed so that the frame with the back body and casters attached is formed separately, and the auxiliary frame attached to the lower frame making up the frame is detachably attached so that the bottom area can be reduced. It is. Further, a hard bottom plate is rotatably attached to the entire inner bottom surface of the bag body. Therefore, when folding a travel bag, first peel off the bottom of the bag body from the lower frame, separate the auxiliary frame from the lower frame, and then raise the bottom plate on the inner bottom of the bag body before folding the bag body. The structure is complicated and the folding work is troublesome. In addition, there are many problems such as the possibility of losing the removed parts.
