[0015] Below, embodiments of the present invention are described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention.

[0016] However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. Furthermore, in order to clearly explain the invention in the drawings, parts unrelated to the description have been omitted, and similar parts throughout the specification have been given similar reference numerals.

[0017] When a part of a specification is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0018] A bag attachment device for a mobility aid according to an embodiment of the present invention will be described in detail below with reference to the drawings.

[0020] FIG. 1 shows a bag attachment device for a mobility aid according to an embodiment of the present invention, FIG. 2 shows a bag according to an embodiment of the present invention, and FIG. 3 and FIG. 4 show a structure in which a bag is attached to a plate according to an embodiment of the present invention.

[0021] Referring to FIGS. 1 to 4, the bag attachment device of a mobility aid according to an embodiment of the present invention is composed of a plate (10) and a bag (20).

[0022] The plate (10) is installed on a mobility aid (not shown), such as a wheelchair, and the bag (20) is detachably attached to the plate (10).

[0023] A plurality of first brackets (12) are installed on the upper part of the plate (10) to which a bag (20) can be detachably fastened. A fixing member (16) is provided on the lower part of the plate (10) to prevent shaking of the bag (20) fastened through the first brackets (12). The fixing member (16) can be configured in various ways depending on the material of the bag (20), and in the embodiment of the present invention, it can be Velcro.

[0024] The bag (20) is composed of a main body (24) capable of holding personal belongings and a lid (26) hinged to the upper part of the main body (24), and the main body (24) has a second bracket (22) installed that is coupled to the first bracket (12) of the plate (10).

[0025] A magnetic bar (121) and an electromagnet (122) are installed in the first bracket (12). Since the polarity of the electromagnet (122) changes according to the button adjustment of the switch (14), the magnetic bar (121) can move through the upper through hole of the first bracket (12) while moving away from or coming into contact with the electromagnet (122) depending on the change in polarity of the electromagnet (122).

[0026] A switch (14) for controlling the polarity of the electromagnet (122) of the first bracket (12) is installed on the side of the plate (10).

[0027] The switch (14) is equipped with multiple buttons, each button being assigned to a specific first bracket (12), so that when any one of the buttons is pressed, the polarity of the electromagnet (122) of the corresponding first bracket (12) changes.

[0028] The switch (14) and the electromagnet (122) of the first bracket (12) are electrically connected through wiring (18), so that the operation of the electromagnet (122) can be controlled by the button operation of the switch (14).

[0029] We will explain in detail the process of a user attaching a bag (20) to a plate (10) installed on a mobility aid.

[0030] First, the user tilts the bag (20) so that the first bracket of the plate (10) can be inserted into the second bracket (22) of the bag (20), thereby bringing the upper part of the first bracket (12) into the upper part of the second bracket (22), and then tilts the bag (20) to the opposite side so that the lower part of the first bracket (12) comes into the lower part of the second bracket (22).

[0031] After the first bracket (12) is inserted into the second bracket (22) in this way, when the user presses the corresponding button of the switch (14) to change the polarity of the electromagnet (122), the polarity of the magnetic bar (121) and the electromagnet (122) becomes the same, causing the magnetic bar (121) to move upward and away from the electromagnet (122).

[0032] When the magnetic bar (121) moves upward, the magnetic bar (121) gets caught on one side catch (221) of the second bracket (22).

[0033] Meanwhile, a hook (123) is installed on the lower part of the first bracket (12), so that when the first bracket (12) is inserted into the second bracket (22), the hook (123) is caught on the other side catch (222) of the second bracket (22).

[0034] Therefore, the first bracket (12) and the second bracket (22) can be stably connected due to the simultaneous engagement of the magnetic bar (121) and the hook (123).

[0035] After the bag (20) is attached to the plate (10) in this way, when the user wants to detach the bag (20) from the plate (10), the user can release the connection between the first bracket (12) and the second bracket (22) by pressing the corresponding button of the switch (14) to change the polarity of the electromagnet (122) and moving the magnetic bar (121) downward.

[0036] In an embodiment of the present invention, a plurality of first brackets (12) are installed on a plate (10), and since a bag (20) can be attached to each first bracket (12), a plurality of bags (20) can be attached to the plate (10) simultaneously. Accordingly, the user can divide their personal belongings among several bags (20).

[0038] The foregoing detailed description should not be interpreted restrictively in all respects and should be considered exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
