Description

  The present invention relates to a bag that can be opened and closed without changing the handle.

  As a function desired for the bag, it is possible to protect the object to be stored from deformation or breakage, to occupy a small area, and to be easily put in and out. In order to satisfy these requirements, it is desirable to have a box-like structure, open from the upper wall to the upper part of the front wall in an upright state, and maintain the opening shape without being spread or suppressed by hand. As this, there is a so-called flight case.

  Another function desired for the bag is that the object can be easily taken in and out with a quick and stable posture when walking or standing. In order to satisfy this, it is desirable that the handle can be opened and closed without changing the handle. However, flight cases do not meet this requirement.

  The problem to be solved by the present invention is to have a box-like structure, open from the upper wall to the upper part of the front wall in an upright state, maintain the opening shape without expanding or suppressing by hand, and changing the handle It is to provide a bag that can be opened and closed without any problems.

  In the present invention, the handle is positioned directly above the center of gravity when standing upright, the handle base is connected to the rear wall or the side wall, and the entire upper wall and the upper front wall are moved to a position where they are close to the lower front wall. Thus, an opening is formed, and the movement is not hindered by the hand holding the handle.

  Further, the opening / closing operation becomes more stable by the additional means. The means is to provide a part that determines the trajectory of the movement of the upper wall.

  Further, by another additional means, when the handle is not held and suspended, a larger opening is obtained, and the loading / unloading of the storage object is further facilitated. The means is to allow the handle to move to a position where the opening is made larger.

  According to the present invention, there is provided a bag having a box-like structure that opens from the upper wall to the upper part of the front wall in an upright state, maintains the opening shape without being spread or restrained by hand, and can be opened and closed without changing the handle. It becomes possible.

  Further, the opening / closing operation becomes more stable by the additional means.

  Further, by another additional means, when the handle is not held and suspended, a larger opening is obtained, and the loading / unloading of the storage object is further facilitated.

Indicates the state during opening and closing.   It is explanatory drawing of the form (Example 1) which shows the most main characteristics of this invention. Indicates the closed state.   It is explanatory drawing of the form (Example 1) which shows the most main characteristics of this invention. The state at the time of opening is shown.   It is explanatory drawing of the form (Example 2) which has a part which defines the locus | trajectory which an upper wall moves. Indicates the state during opening and closing.   It is explanatory drawing of the form (Example 2) which has a part which defines the locus | trajectory which an upper wall moves. The state at the time of opening is shown.   It is explanatory drawing of the form (Example 3) which a handle can move to the position which enlarges an opening more. The handle is moved to the rear wall side.

  Hereinafter, modes for carrying out the present invention will be described.

  An embodiment of the mode showing the most important features of the present invention is shown in FIGS. 1 shows a state during opening and closing, FIG. 2 shows a closed state, and FIG. 3 shows a opened state.

  When closed, the box is surrounded by a plate-like wall. The handle base 2 is connected to the rear wall 4, and the handle 1 is held just above the center of gravity when the bag is upright by a support 3 extending obliquely upward from the handle base 2. The upper wall 5 is connected to the front wall upper part 6 via a hinge 9. The front wall upper part 6 is connected to the front wall lower part 7 through a hinge 10. These hinges 9 and 10 are capable of rotating around the position where the parts to be connected are opposed, and may be bent using the flexibility of an elastic body, for example, It may be one that rotates about an axis. By rotating through the hinges 9 and 10, the upper wall 5 and the front wall upper part 6 can move to positions close to the front wall lower part 7 as shown in FIG. The position is the opening. The upper wall 5 alone has a shape that does not surround the handle base 2, and the movement of the upper wall 5 and the front wall upper portion 6 is not hindered by the hand holding the handle 1. Thereby, it can open and close without changing the handle 1.

  In addition, the upper wall 5 and the front wall upper part 6 are detachably fixed by a fastener (not shown) so as not to open against the user's will. For example, a magnet can be provided at a position where the upper wall 5, the front wall upper portion 6 and the side wall 8 are in contact with each other when the mouth is closed. In order to secure the upper wall 5 and the front wall upper part 6 more securely, an element functioning as a lock may be provided instead of or in addition to the magnet.

  In addition to the features shown in the first embodiment, an embodiment having a part that defines the trajectory of movement of the upper wall 5 is shown in FIGS. 4 shows a state during opening and closing, and FIG. 5 shows a state when opening. The arm 11 is connected to the side wall 8 so as to be rotatable about a rotation axis 13 perpendicular to the side wall 8, and has a hinge 12 having another rotation axis 14 perpendicular to the side wall 8. It is connected to the upper wall 5 via. The shapes, dimensions, and positions of the arm 11 and the hinge 12 are set so that the position of the upper wall 5 when closing, during opening / closing, and when opening is appropriately determined. Thereby, the locus | trajectory which the upper wall 5 moves becomes settled, and opening / closing operation | movement becomes more stable. In addition, the external appearance at the time of closing is the same as FIG. 2 shown in the first embodiment.

  In addition to the features shown in the second embodiment, FIG. 6 shows an embodiment in which the handle 1 can be moved to a position where the opening is made larger. The handle 1 and the support 3 can be rotated and moved toward the rear wall 4 around a rotation axis 15 perpendicular to the side wall 8. Furthermore, the handle base 2 and the support 3 have elements (not shown) that allow the rotational movement to be fixed and released freely. As a result, the handle 1 can be held and suspended in a state where the handle 1 is fixed directly above the center of gravity of the bag. When the handle 1 is not held and suspended, a larger opening can be obtained, and the storage of objects can be further performed. It becomes easy. FIG. 6 shows a state in which the handle 1 and the support 3 are moved to the rear wall 4 side.
