Description

  The present invention relates to an improvement in a relatively small traveling bag with casters that can be carried on an airplane.

Conventionally, there are a wide variety of travel bags with casters ranging from a large size of 110 liters to a small size of 30 liters, most of which are bag bodies that are formed by opening and closing a pair of shells that are open on one side. When the caster with the traveling wheel of the same diameter is attached to the bottom four corners of the bag body, or the caster with the traveling wheel is attached to one side shell of the pair of shells constituting the bag body, A small traveling bag or the like that has a small caster with a small-diameter auxiliary wheel attached to the opposite shell bottom surface or is provided with a locking projection to facilitate laundering is known (references 1, 2, and 3). .

  The travel with the travel bag is usually in a vertically long state, the four casters are grounded to the floor, and are moved horizontally while holding the handle attached to the top surface of the travel bag, or in the vertically long state. He has a handle handle attached to the upper end of the bag, tilts the travel bag, and coasts using casters attached to both ends on the wide side.

  The caster attached to the bottom of the travel bag with casters has a small traveling wheel diameter.If the bag is loaded with luggage, the bag will become heavier and the load on the wheel will increase when moving. It is difficult to move. Moreover, when the diameter of the traveling wheel is too large, there is a problem that the wheel is likely to jump during movement and the stability is deteriorated.

  Therefore, the diameter of the traveling wheel attached to the caster used for the luggage is usually 30 to 50 mm. Therefore, when a caster having the above diameter is attached to the bottom surface of the travel bag, a gap of about 70 to 80 mm is formed between the bottom surface and the floor surface of the travel bag. Since the casters of the same size are attached to the casters attached to the travel bags with casters regardless of the size of the bags, the distance between the bottom and the floor of the travel bags is almost the same.

  On the other hand, a caster of the same size as the above-mentioned caster is also attached to a travel bag of a size that can be carried on an airplane. Therefore, the clearance between the bottom surface and the floor surface of the travel bag has a gap of about 70 to 80 mm, as in the case of the large travel bag. The size of the carry-on luggage is slightly different depending on the airline, but the average size is the sum of the three sides of length x width x height is within 115 cm and the weight is within about 18 kg. In particular, there are many places where the vertical length is restricted within 550 mm.

  Therefore, a travel bag with a caster for carrying onboard is usually formed in a size within the above-mentioned limit, and in particular, a vertical length is formed within 550 mm. However, some airlines set the vertical length lower. However, the bag size is not accurately measured at the time of boarding, so it may appear larger depending on the color and shape of the bag, and it may be checked even if the vertical length limit is cleared. It is troublesome.

  In addition, it is possible to investigate the carry-on restrictions of the airline that you board in advance, but it may be unclear when and where the airline will board the flight because you do not know what will happen. The preliminary survey is meaningless and troublesome.

  The problem to be solved by the present invention is that the position of the caster attached to the travel bag with casters, particularly the relatively small type of carry bag for carry-on, is not the bottom of the bag body, but the bottom and floor surfaces of the travel bag. The height limit of the airline that limits the carry-on of the average size by reducing the height of the travel bag by reducing the distance of the travel bag can be cleared, and the travel when moving the travel bag is stabilized, and An object is to reduce the weight and improve the strength of the bag body.

  In order to achieve the above-described object, the present invention is configured by bending a pair of shells 3 and 4 formed in a substantially rectangular shape with an opening on one side thereof into a substantially triangular shape, respectively, by vertically extending the entire lower side or both ends of the wide surface portion 5. The bag body 2 is formed integrally with the chamfered portion 10 and both the longitudinal edges of the shells 3 and 4 are connected to each other by hinges 11 so as to be openable and closable, and the chamfered portion 10 of the bag body 2 A chamfer receiving portion 16 to be joined is provided on the upper surface, a caster receiving portion 25 is formed in a horizontal direction on the lower surface of the chamfer receiving portion, and the caster 31 is vertically deviated from the center of the ceiling of the caster receiving portion. A caster holder 15 formed by vertically providing a bearing recess 26 for mounting the shaft 32 and a lower portion of the vertical shaft 32 attached to the bearing recess 26 provided in the caster receiving portion 25 of the caster holder 15 are formed in a substantially gate shape. The support frame 33 is pivotally supported so as to be rotatable in the horizontal direction, and a caster 31 formed by pivotally supporting a traveling wheel 36 that rotates in a direction perpendicular to the support frame at the tip of the support frame. Features. Further, the caster holder 15 has a chamfering receiving portion 16 provided on the surface thereof at an upper end of a slope portion 17 inclined at the same angle as the chamfering portion 10 of the bag main body 2 and the surface portion 5 of the bag main body 2. A vertical portion 18 to be joined is provided, and a horizontal portion 20 to be joined to the bottom surface portion 7 of the bag body 2 is provided at the lower end of the chamfer receiving portion 16, either one of the left and right ends of the slope portion 17, the horizontal portion 20, and A locking wall portion 22 is formed integrally with one end of the vertical portion 18. Further, the chamfering receiving portion 16 provided on the surface of the caster holder 15 has a plurality of chamfering portions S formed in a substantially triangular shape in a chamfered portion S formed by cutting the upper portion from the approximate center of the inclined surface portion 17 into a substantially triangular shape. The rib pieces 17a are established at regular intervals, and are formed integrally with an inclined surface 17b continuously provided below the inclined surface portion 17.

  Accordingly, the caster holder 15 is attached to the chamfered portion 10 provided on the lower side of the surface portion 5 of the bag body 2, and the caster 31 is attached to the caster holder, so that the shaft of the traveling wheel 36 attached to the caster is attached. The heart can be brought close to the bag body 2, and the distance between the bottom surface and the floor of the bag 1 can be shortened to shorten the overall height of the bag. Therefore, the height of carry-on restrictions of each airline can be cleared, the travel of the caster 31 can be stabilized when the travel bag 1 is moved, and the strength and weight of the bag body can be reduced. .
