[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a bag with casters for traveling.

[0002]

[Prior art]

 Since the bag with casters can be pulled and moved, it has the feature that it can be moved easily and lightly even if it is heavy. However, the bag with casters has the drawback that it tilts greatly when moving on an escalator. Both casters cannot be placed on horizontal stairs.

In order to prevent this drawback, a bag having a protrusion between casters has been developed (Japanese Utility Model Laid-Open No. 63-25023). The bag described in this publication has long projections 8 between casters 1, as shown in FIG. The protrusions 8 are lower than the casters 1 so that they do not interfere with the movement of the bag on a flat surface. As shown in Fig. 1, the bag with the convex portion 8 has a feature that it can be easily moved by sliding the corner of the stairs. Further, when moving by an escalator, as shown in FIG. 2, the convex portion 8 is placed on the stairs of the escalator so that it can be easily moved in a substantially horizontal posture.

[0004]

[Problems to be solved by the device]

 The bag with this structure has the feature that the casters can run on a flat place and can be easily moved by using the convex portion 8 on stairs and escalators. However, when the caster is lifted and transported without using the caster, the caster 1 has a disadvantage of becoming heavy. In particular, a bag provided with sturdy and large casters so that heavy items can be stored and transported can be difficult to lift because the side to which the casters are fixed becomes heavy. Especially, since the grip of the bag is provided in the center, a bag with sturdy and large casters has a drawback that it cannot be lifted in a balanced manner.

The present invention was developed for the purpose of solving this drawback. An important purpose of this plan is to provide a bag with casters that can be easily lifted and transported even if the bag is sturdy and has large casters by using the convex portion for the escalator together with the grip.

[0006]

[Means for Solving the Problems]

 The bag with casters of the present invention has the following structure to achieve the above-mentioned object. The bag has casters 1 at four corners on one side. Escalator projections 6 are provided between the casters 1. The escalator protrusion 6 is used as shown in FIG. That is, when the bag is placed on the escalator, the convex portion 6 for the escalator can be placed on the corner of the escalator to keep the bag substantially horizontal. Therefore, a heavy bag can be easily moved on the escalator. The convex portion 6 for the escalator is designed lower than the caster so as not to get in the way when moving on a normal plane. Furthermore, the bag of the present invention is provided with a grip 7 on the convex portion 6 for the escalator. Therefore, when a heavy baggage is stored and carried in the bag, both the grip 7 of the convex portion 6 for the escalator and the grip 9 of the bag can be carried easily.

[0007]

[Action]

 The bag of this invention can be easily moved by an escalator. This is because, as shown in FIG. 4, the convex portion 6 for the escalator can be placed on the stairs of the escalator to be substantially horizontal. The bag inclines slightly when moving on an escalator, but the angle of inclination is so small that you can easily move it with your hand. Furthermore, when carrying, as shown in FIG. 3, both the grip 9 of the bag and the grip 7 of the convex portion 6 for the escalator can be lifted. For this reason, when carrying a heavy object in a bag, it is possible to easily carry it in two places.

The bag with casters shown in FIGS. 3 to 6 is composed of a bag body 2 and a lid body 3, and the whole shape is an elongated box shape. The bag body 2 is provided with a U-shaped grip 9 at the center of the long side and a caster 1 on one side of the short side. The caster 1 is fixed to the wheel stand 5 via the reinforcing gap plate 4. The wheel stand 5 is provided with a convex portion 6 for the escalator projecting to the lower surface.

The bag body 2 is connected to a lid body 3 that can be opened and closed via a hinge. The bag main body 2 and the lid 3 are made of a material having sufficient strength, for example, a fibrous material is cured and bonded with a binder to form a plate, and a water-resistant hard paper coated with a paint. Molded with hard plastic, metal such as aluminum.

The bag body 2 and the lid body 3 are designed to have a thickness that does not deform even if a considerably heavy item is stored. The size of the bag is designed to have a height of 50 to 200 cm, a width of 20 to 100 cm, and a thickness of 10 to 60 cm in a vertically long state.

As shown in the bottom view of FIG. 5 and the perspective view of FIG. 6, the escalator projection 6 is a metal plate and is fixed in two rows extending in parallel in the longitudinal direction on both sides of the caster mounting surface. It The convex portion 6 for the escalator is made of the same material as the bag body instead of the metal plate, for example, a fibrous material is hardened and bonded with a binder to be molded into a plate shape, and a paint is applied on the surface of water-resistant hard paper. It is also possible to use a material coated with or a hard plastic. The escalator protrusion 6 is designed to be lower than the caster 1 by preferably 5 to 20 mm so that it does not come into contact when the bag is moved to a flat place. The escalator convex portion 6 is provided with a grip 7 by opening a through hole in a slit shape. The grip 7 of the through hole has a feature that it is easy to grip.

Further, in the bag shown in FIGS. 7 and 8, a box-shaped escalator projection 6 is fixed to the caster mounting surface. The escalator protrusion 6 has grips 7 penetrating the side plates on all the peripheral surfaces, that is, four sides of the box shape.

The escalator protrusion 6 shown in FIG. 9 has a through hole to form a grip 7, and the escalator protrusion 6 shown in FIG. 10 has ridges protruding from both sides of the lower edge to form a grip 7.

The reinforcing gap plate 4 is fixed to the bag body 2 via screws or rivets. The reinforcing gap plate 4 is a plywood. However, the reinforcing gap plate 4 may be a metal plate or a hard rubber plate. The outer shape of the reinforcing gap plate 4 is almost the same as the caster mounting surface of the bag body 2. Therefore, the reinforcing gap plate 4 is fixed on the entire caster mounting surface of the bag body 2. The reinforcing gap plate 4 reinforces the caster mounting surface of the bag body 2 to fix the wheel stand 5, and as shown in FIG. 6, provides a gap between the lid body 3 and the wheel stand 5. The gap between the lid body 3 and the wheel stand 5 prevents the lid body 3 that is opened and closed from coming into contact with the wheel stand 5. Therefore, the thickness of the reinforcing gap plate 4 is designed to have a gap between the lid body 3 and the wheel stand 5 and to reinforce the caster mounting surface of the bag body 2. The thickness of the reinforcing gap plate 4 made of plywood is preferably about 10 mm. However, the thickness of the reinforcing gap plate 4 is changed to an optimum value depending on the size of the bag and the material of the reinforcing gap plate 4.

The optimum material for the reinforcing gap plate 4 is plywood, but a hard rubber plate can also be used. It is also possible to use the reinforcing gap plate 4 as a shock absorbing material acting on the wheel stand 5 by adhering the reinforcing gap plate 4 of a hard rubber plate to the bag body 2 and also adhering the wheel base 5 thereto. it can. This is because the rubber plate protects the bag body 2 by absorbing the shock of the wheel stand 5.

The reinforcing gap plate 4 is preferably fixed to the entire caster mounting surface of the bag body 2. However, the reinforcing gap plate 4 does not necessarily have to be fixed to the entire caster mounting surface of the bag body 2. The reinforcing gap plate can be made smaller than the caster mounting surface of the bag body.

As shown in FIG. 7, the wheel base 5 has a size that extends from the caster mounting surface of the bag body 2 to the lower surface of the lid body 3, and is provided with an escalator convex portion 6 protruding from the lower surface. ing. The wheel stand is fixed to the bag main body 2 via screws or rivets, or fixed to the reinforcing gap plate 4. When the wheel base 5 is fixed to the bag body 2, the reinforcing gap plate 4 is sandwiched and fixed. The wheel base 5 can also be fixed to the reinforcing gap plate 4 by bonding. The wheel base 5 is made of a metal plate such as aluminum so as to have sufficient strength. The wheel base 5 made of aluminum preferably has a thickness of 2 to 5 mm, more preferably 3 to 4 mm. In order to make the wheel stand 5 of FIG. 1 lighter, a through hole is partially opened.

The casters 1 and the escalator projections 6 are fixed to the wheel base 5. The casters 1 are located at the four corners of the bag and fixed to the wheel base 5. The caster 1 is one that can be swung freely. However, not all of the four casters 1 are of the swing type, but the two casters 1 arranged on one side of the bag body 2 are of the swing type, and the other two casters 1 are the swing type. It is also possible that it is not a swing type. The caster 1 is fixed to the lower surface of the wheel stand 5 with screws or rivets.
