DETAILED DESCRIPTION

(10) Now, embodiments of the present invention will be described. However, the embodiments below are illustrative only and do not limit the scope of the present invention.

1. First Embodiment

(11) Referring now to FIGS. 1 to 7, a bag 100 according to a first embodiment of the present invention will be described. The bag 100 includes a bag body including a front part 1 shown in FIG. 1 and a rear part 2 shown in FIG. 2, an opening 3 provided on the upper edge of the bag shown in FIG. 4, and a shape keeping part that prevents closing of the opening 3 and keeps the bag body expanded. As shown in FIGS. 3A and 3B, in the present embodiment, the shape keeping part is made up of connectors 5, 6 that are disposed on both ends of a fastener 4 and can be connected to each other.

(12) In the present embodiment, the bag body has a two-layer structure and comprises an outer leather bag body and an inner felt bag body. Note that these bodies need not be formed of the above materials and may be formed of any material in accordance with the application. Also, in the present embodiment, upper portions of the front part 1 and rear part 2 are formed of felt 9 in order to improve the appearance.

(13) The fastener 4 is disposed along the length direction of the opening 3. The bag body can contain an object in the bag body with the opening 3 opened. The fastener 4 includes a slider 41, a tape 42, and elements 43. The slider 41 has a function of engaging the elements 43 with each other, and the opening 3 can be switched between open and close states by moving the slider 41. The tape 42 is a part on which the elements 43 are disposed. The elements 43 are engaged with the slider 41 so that the slider 41 can move. When the elements 43 are engaged with each other and thus closed, the opening 3 is placed in a close state.

(14) Both ends of the fastener 4 are adjacent to both ends in the length direction of the opening 3 and are provided with connectors 5, 6. The connectors 5, 6 can be connected to each other. By connecting the connectors 5, 6 to each other, both ends in the length direction of the opening 3 come close to each other.

(15) As shown in FIGS. 3A and 3B, in the present embodiment, the connector 5 includes an engagement part 51 and notches 52. The connector 6 has an opening 61. As shown in FIG. 4, by inserting the engagement part 51 into the opening 61 and rotating it by approximately 90°, a T-shaped portion of the engagement part 51 is caught on both sides of the opening 61 and thus the connectors 5, 6 are mounted to each other. As seen above, the connectors 5, 6 are configured to be connectable to each other by engagement. By connecting the connectors 5, 6 to each other, the bag body is kept expanded. That is, the fastener 4 can be said to be a fastener having the connectors (connectors 5, 6) connectable to each other on both ends thereof.

(16) As shown in FIGS. 1 and 2, deformation promotion parts 7 (shown by white broken lines; the same applies to other drawings) configured to form protrusions protruding from the side surfaces of the bag body toward the center of the bag body are disposed near lower edges of the front part 1 and rear part 2 of the bag body. In the present embodiment, the deformation promotion parts 7 are seams, and the front part 1 and rear part 2 can be folded toward the inside of the bag body along the deformation promotion parts 7. The inner felt bag body preferably has a shape that is not present in a triangular region formed by the deformation promotion parts 7, front part 1, and rear part 2. The reason is that the absence of the felt bag body in the triangular region allows the front part 1 and rear part 2 to be easily folded toward the inside of the bag body.

(17) When the front part 1 and rear part 2 are folded toward the inside of the bag body along the deformation promotion parts 7 with the connectors 5, 6 mounted to each other and then the bag 100 is turned over, the bag 100 becomes a state shown in FIGS. 5A and 5B. Since the opening 3 is prevented from being closed by the connectors 5, 6 and the bag 100 is kept expanded, the bag 100 can stand on its own on the table or floor. Also, by folding the front part 1 and rear part 2 toward the inside of the bag body along the deformation promotion parts 7, a placement surface 10 is formed around the deformation promotion parts 7.

(18) FIG. 6 is a drawing showing an example use of the bag 100 in the state in FIGS. 5A and 5B. While, in the present embodiment, a headphone 20 is placed on the placement surface 10, any other object may be placed on the placement surface 10. For example, a portable information terminal such as a smartphone, or a small article such as a pen, glasses, or chewing gum may be placed on the placement surface 10.

(19) As shown in FIGS. 1 and 2, string member mounting rings 8 are disposed near the boundaries between the front part 1 and rear part 2, and the felt 9. As shown in FIG. 7, both ends of a string member 30 may be mounted to the bag 100 through the string member mounting rings 8 as necessary.

(20) As described above, according to the present embodiment, the bag 100 turned over can stand on its own on the table, and an object can be placed on the placement surface 10 formed by the deformation promotion parts 7. Thus, a placement place for an object such as the headphone 20 can be secured even on a narrow table in a coffee shop or the like.

(21) The present invention may be carried out in the following forms.

(22) While, in the present embodiment, the engagement part 51 (T-shaped portion) and opening 61 of the connectors 5, 6 are engaged with each other, the connectors 5, 6 may be connected to each other using a different element (e.g., button, eyelet, hook-and-loop fastener, string).
While, in the present embodiment, the connectors 5, 6 are connected to each other by engaging them with each other, the connectors 5, 6 may be connected to each other by magnetic force or adhesion.
While, in the present embodiment, the fastener 4 is disposed on the opening 3, the fastener 4 may be omitted. In this case, the connectors 5, 6 may be disposed in any positions adjacent to both ends in the length direction of the bag body. For example, the connectors 5, 6 may be disposed in regions Y and Z in FIG. 9. For another example, as shown in FIG. 8A, the connectors 5, 6 may be disposed inside the bag body. In this case, the connectors 5, 6 becomes a state shown in FIG. 8B by connecting them to each other.
While the bag body including the front part and rear part facing each other has been described, the present embodiment can also be applied to a bag shaped such that the front part and rear part are not clearly distinguished from each other. In this case, a part of the bag body is regarded as the front part, and a part facing the front part is regarded as the rear part.

2. Second Embodiment

(23) Referring now to FIG. 9, a second embodiment of the present invention will be described. The present embodiment is similar to the first embodiment, and a major difference therebetween is the configuration of a shape keeping part. The following description will focus on the difference.

(24) In the present embodiment, as shown in FIG. 9, an inside support member 70 is disposed in a bag body and forms a shape keeping part. Since the inside support member 70 prevents a front part 1 and a rear part 2 from coming close to each other, the bag body is kept expanded. If the bag 100 is not deformed, the inside support member 70 may be stored in, for example, a pocket inside the bag 100 in advance. Or, a part of the inside support member 70 may be fixed to the inner surface (e.g., a portion shown by a region X) of the bag 100 in advance.

(25) The inside support member 70 may have any shape as long as it can prevent the front part 1 and rear part 2 from coming close to each other. For example, it may have a rod shape as shown in FIG. 9, or may have any other shape such as a circle.

3. Third Embodiment

(26) Next, a third embodiment of the present invention will be described. The present embodiment is similar to the first embodiment, and a major difference therebetween is the configuration of a shape keeping part. The following description will focus on the difference.

(27) In the present embodiment, a front part 1 and a rear part 2 of a bag body are provided with part shape keeping members that when the front part 1 or rear part 2 is deformed, keep the part deformed, and the part shape keeping members form a shape keeping part. The part shape keeping members are formed of members, such as metal sheets, that can be easily plastically deformed. Such members are inserted into the front part 1 and rear part 2 or pasted on them. Thus, when the front part 1 and rear part 2 are deformed so that the bag body is expanded, the front part 1 and rear part 2 are kept deformed by the part shape keeping members. While both the front part 1 and rear part 2 are preferably provided with part shape keeping members, only one of them may be provided with a part shape keeping member.

4. Others

(28) While, in the above embodiments, the bag 100 is used as a headphone stand, the use of the bag 100 is not limited to a headphone stand. For example, the bag 100 can be used as an electronic device by inserting an electronic device, such as a speaker, into the front part 1, rear part 2, or any other portion of the bag 100. Also, the bag 100 can be used as an objet d'art by forming a pattern or illustration on the deformed (that is, turned-over) bag 100.
