Description

[Technical field]

[0001] The present invention relates to an expandable, size-adjustable carry case in which the soft case, which serves as the storage space and is composed of a bottom frame, soft case fabric, a soft case fabric joining frame, an expandable slide handle rail, and a top plate, expands and contracts vertically, and the storage capacity can be changed by adjusting the size of the soft case along the vertical axis. [Background technology]

[0002] Generally, hard case types made of hard materials such as aluminum or polycarbonate, and soft case types made of materials such as nylon or polyester are known.

[0003] Traditionally, suitcases are designated by their storage capacity, such as for one night and two days or 75L, and the dimensions and capacity of the suitcases are set accordingly.

[0004] By the way, when choosing a carry case, you have to select the size and capacity according to the purpose of use, and in some cases you have to be bothered by having to own multiple cases.

[0005] For this reason, a carry case has been proposed in which two hard cases are stacked on top of each other and can be expanded and contracted vertically to increase or decrease the storage capacity by utilizing the capacity of each hard case (see Non-Patent Document 1). [Prior art documents] [Non-patent literature]

[0006] [Non-Patent Document 1] https: / / www.veloluggage.com Summary of the Invention [Problem to be solved by the invention]

[0007] However, the proposal in Non-Patent Document 1 has the problem that it is heavy because it requires a large hard case and a small hard case, and when shrinking it, the large hard case is placed over the smaller one, so if the smaller hard case does not have a certain size or larger, it will affect the overall storage capacity.

[0008] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an extendable, size-adjustable carry case in which the storage capacity can be increased or decreased, the soft case serving as the storage space being composed of a bottom frame, soft case fabric, soft case fabric joining frame, extendable slide handle rails, and a top plate can be extended and retracted up and down, and can contract to a flat surface when not in use, and the soft case and the hard case serving as the storage space can be integrated, the soft case and the hard case can be fused together, the soft case is lightweight, and even if the vertical dimension of the hard case is designed to be short, the storage capacity is not affected if the vertical dimension of the soft case is designed to be long, so that the storage capacity can be increased or decreased. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention comprises the following means 1) and 2). That is, 1) An extendable, size-adjustable carry case comprising a bottom frame, soft case fabric, a carry handle, a telescopic slide handle rail, a soft case fabric joint frame, a top plate, and casters, the telescopic slide handle rails being fixedly joined to the inside of both side surfaces of the bottom frame which is composed of a front panel, a back panel, a side panel, and a bottom panel, the soft case fabric joint frame being fixedly joined to the outside of the telescopic slide handle rail, the top plate being fixedly joined to the top of the telescopic slide handle rail, and the soft case fabric being fixedly connected to the outside of the soft case fabric joint frame, the top plate, and the inside of the bottom frame, so that the soft case fabric becomes a soft case which serves as storage space, the soft case telescopically moves up and down in synchronization with the telescopic function of the telescopic slide handle rail, and the size of the soft case from the top plate to the bottom frame can be adjusted in stages according to the storage capacity. 2) The expandable, size-adjustable carry case described in 1) is characterized in that it has a case that serves as a storage space composed of a front panel, a back panel, side panels and a bottom panel instead of the bottom frame, an opening and closing part is provided on the front panel to form a hard case that can be opened and closed with a zipper, the hard case and the soft case are fixed and joined together to form a single unit, allowing the hard case and the soft case to be used simultaneously, and the size of the soft case can be adjusted in stages depending on the storage capacity. Effect of the Invention

[0010] According to the present invention, when the storage capacity is small, the soft case serving as the storage space can be used in a small size, and when the storage capacity is large, the soft case can be used in a large size, making it possible to gradually change the size of the soft case according to the amount of carrying capacity, thereby providing an extendable, size-adjustable carry case in which the soft case and the hard case serving as the storage space can be integrated into one.

The soft case fabric joining frame 6 is a frame formed so that a part of both ends of the frame on one side of the four sides is left, and the remaining part becomes the soft case fabric joining frame claws 6a. The bottom frame 1 may be made of a hard and light material such as aluminum, ABS resin, polycarbonate, etc. The soft case fabric 2 may be made of a soft and lightweight material such as nylon, polyester, synthetic leather, etc. The top plate 5 may be made of the same material as the bottom frame 1. The connecting parts 10 may be made of, for example, caulking, bolts, screws, adhesives, etc. The telescopic slide handle rail 7 has a telescopic function and can be fixed and released at certain points, and the telescopic function allows the soft case fabric 2 fixed and joined to the soft case fabric joining frame 6 to telescope up and down.The telescopic function of the telescopic slide handle rail 7 can be fixed and released in stages by a switch at hand, and the material can be freely determined in terms of strength and design. The material of the soft case fabric joint frame 6 can be freely determined in terms of strength and design. The carry handle 8 has a telescopic function, and can be fixed and released in stages by a switch at hand, and the material can be freely determined in terms of strength and design. The zipper 3 is a double-opening type with two sliders and may be equipped with a security key. The number of casters 9 may be two instead of four.
