Description

Carrier bag braking system

[0001] The present invention relates to a braking device for a carrier bag that is installed on the carrier bag and allows the user to brake the carrier when desired.

[0002] A suitcase is a bag used to store and transport various items, including clothing, during travel or business trips. However, due to the nature of suitcases, which rely on wheels for movement, they can be vulnerable to loss of control on downhill slopes or slippery surfaces.

[0003] To solve these problems, it is necessary to provide a braking device on the carrier bag. In this regard, the prior Korean Registered Utility Model No. 20-2018-0004147 discloses a carrier device for a travel bag.

[0004] However, the aforementioned prior art only has a support bar installed, so it is applicable only to two-wheeled travel bags and only has the effect of fixing to the ground when the bag stops moving.

[0005] As part of solving the aforementioned problem, the present invention aims to provide a braking device for a carrier bag capable of braking the carrier bag.

[0006] The braking device of a carrier bag according to the present invention is characterized by comprising at least two wheels provided on the lower part of the carrier bag, a retractable handle provided on one side of the carrier bag, a handle column connected to the lower part of the handle, a fixing button provided on the upper part of the handle, an inlet / outlet section where the handle is located when the handle is fully retracted, a braking section in contact with the handle column, and a housing that accommodates the braking section.

[0007] In addition, it is characterized by including a locking part provided at the bottom of the inlet / outlet section.

[0008] In addition, the braking unit is characterized by including a brake plate provided inside the housing and a rotating shaft connected to the brake plate.

[0009] In addition, the braking unit is characterized by including an arch brake plate provided inside the housing and a spring provided between the lower part of the arch brake plate and the housing.

[0010] According to the present invention, the carrier bag can be braked at the user's will even while in motion by means of a braking device of the carrier bag.

[0011] In addition, when the carrier bag stops moving, it can stop in a fixed position through the braking device.

Additionally, identical reference numerals throughout the specification refer to identical components. Furthermore, singular expressions in this specification include plural forms unless specifically stated otherwise.

[0023] Hereinafter, a braking device for a carrier bag according to the present invention will be described with reference to the drawings.

[0024] FIG. 1 is a perspective view of a braking device for a carrier bag according to the present invention, FIG. 2 is a front view in the Y direction according to FIG. 1, and FIG. 3 is an enlarged view of part A shown in FIG. 2.

[0025] Here, to aid in understanding the present invention, the first embodiment shown in FIGS. 4a and 4d is referred to as a ground braking method, the second embodiment shown in FIGS. 5a and 5f as a wheel braking method, and the third embodiment shown in FIGS. 6a and 6b as a spring braking method.

[0026] Referring to FIG. 1, the braking device (1000) of the carrier bag according to the present invention may include a wheel (100), a handle (200), a handle column (300), a fixing button (400), an input / output part (500), a braking part (600), and a housing (700).

[0027] At least two wheels (100) may be provided on the bottom of the carrier bag. Additionally, the wheels (100) can move the carrier bag. Additionally, the wheels (100) can rotate 180 degrees around an axis perpendicular to the ground.

[0028] A handle (200) may be provided on one side of the carrier bag. Additionally, the handle (200) can be adjusted in direction when the user drags the carrier bag along the ground. Additionally, the handle (200) may be a cuboid or various other shapes.

[0029] A handle column (300) may be provided connected to the lower part of the handle (200). Additionally, the handle column (300) may support the upper handle (200). Furthermore, the handle column (300) may be moved in and out along the inner space of the carrier bag in a direction perpendicular to the ground by the movement of the handle (200). Additionally, the number of handle columns (300) may be determined according to the type of carrier bag and the user's needs.

[0030] A fixing button (400) may be provided on the upper part of the handle (200). More specifically, when the fixing button (400) is pressed by a user, the handle (200) may move freely up and down, but when the fixing button (400) is released, the handle (200) may be fixed and not move. The fixing button (400) may utilize various methods applicable to the fixing button (400) installed on commercially available carrier bags.

[0031] The inlet / outlet section (500) is provided at a position where the handle column (300) on one side of the carrier bag is inserted and removed. Additionally, the inlet / outlet section (500) is a position where the handle (200) is received when the handle (200) and the handle column (300) are fully inserted, allowing for neat storage without interfering with the user. Furthermore, the inlet / outlet section (500) can be formed in an appropriate shape and size depending on the type and size of the handle (200) and the handle column (300).

[0032] The braking unit (600) may be provided on the opposite side of the bottom of the carrier bag relative to the inlet / outlet unit (500). Additionally, the braking unit (600) may come into contact with the handle column (300) when the handle column (300) is retracted. More specifically, when the handle column (300) is retracted, the handle column (300) may actuate the braking unit (600) to brake the carrier bag. Furthermore, the shape and position of the braking unit (600) may change according to three embodiments: ground braking method, wheel braking method, and spring braking method.

[0033] The housing (700) may be provided at the bottom of the carrier bag at a position symmetrical to the inlet / outlet part (500) in a direction perpendicular to the ground. Additionally, the housing (700) may accommodate the braking part (600). Furthermore, the housing (700) may be formed in size and shape according to an embodiment of the braking part (600).

[0034] The locking part (800) is provided on one side of the lower carrier bag of the inlet / outlet part (500). Also, referring to FIG. 3, the locking part (800) may include at least one hollow part. More specifically, when a user inserts the handle column (300), the locking part (800) allows the handle (200) to be inserted more easily by placing a finger in the hollow part of the locking part (800) and pushing the handle in a gripping manner with the handle (200) and the locking part (800). Additionally, the locking part (800) may be made of metal, plastic, or various other materials that are resistant to deformation due to external forces.

[0035] FIGS. 4a and 4b are cross-sectional views in the Y direction according to FIG. 1 showing a first embodiment of a braking device for a carrier bag according to the present invention, FIG. 4c is a cross-sectional view in the X direction according to FIG. 1 showing a first embodiment of a braking device for a carrier bag according to the present invention, and FIG. 4d is a bottom view in the Z direction according to FIG. 1 showing a first embodiment of a braking device for a carrier bag according to the present invention.

[0036] Referring to FIGS. 4a and 4b, the ground braking type braking unit (600) may include a brake plate (610) and a rotation axis (620).

[0037] The brake plate (610) is provided inside the housing (700). Additionally, the brake plate (610) may be rectangular, trident-shaped, or any other shape capable of generating frictional force by contacting the ground. Furthermore, the part of the brake plate (610) that contacts the ground may be made of rubber, have a protruding structure, or utilize various other means to maximize frictional force. Additionally, the brake plate (610) may be replaced if it wears out due to frictional force with the ground.

[0038] Referring to FIG. 4c, the rotation axis (620) may be provided connected to the brake plate (610). Additionally, the rotation axis (620) may be provided fixed to one side inside the housing (700) so that the brake plate (610) can be rotated around the rotation axis (620). Additionally, a torsion spring may be used for the rotation axis (620).

[0039] Here, a torsion spring is a type of coil or helical spring that responds to rotational force to provide torque or use stored rotational energy.

[0040] Additionally, referring to FIG. 4d, when the carrier bag moves, the braking unit (600) may be contained within the housing (700).

[0041] Here, in the ground braking method, when the handle (200) is fully retracted, the handle column (300) pushes the brake plate (610) out of the housing (700), causing the brake plate (610) to unfold. Then, the carrier bag can be braked by friction with the ground. More specifically, the rotation axis (620) is made of a torsion spring, so when the handle (200) that was pressing the brake plate (610) is pulled out, the brake plate (610) returns to the housing (700) by the elasticity of the torsion spring.

[0042] FIGS. 5A and 5B are cross-sectional views in the Y direction according to FIG. 1 showing a second embodiment of a braking device for a carrier bag according to the present invention, FIGS. 5C and 5D are drawings showing a second embodiment of a wheel braking method shown in FIGS. 5A and 5B, and FIGS. 5E and 5F are drawings showing a third embodiment of a wheel braking method shown in FIGS. 5A and 5B.

[0043] Referring to FIGS. 5a and 5b, in the case of a wheel braking system, the braking unit (600) may include a flat plate (630), a link, and at least two contact brakes (670).

[0044] The flat plate (630) may be provided inside the housing (700). Additionally, it may come into contact with the retracted handle column (300). Furthermore, the flat plate (630) may actuate the braking unit (600) by means of the retracted handle column (300).

[0045] The link may be provided at the bottom of the flat plate (630). Additionally, the link may include an upper link (640), a hinge (650), and a lower link (660).

[0046] The upper link (640) can be connected to the flat plate (630).

[0047] The hinge (650) may be provided connected to the upper link (640). Additionally, the hinge (650) is provided fixed to the housing (700). Furthermore, the hinge (650) may use a torsion spring or various other means capable of transmitting applied external force into rotational force.

[0048] The lower link (660) can be provided connected to the hinge (650).

[0049] A contact brake (670) may be provided at the end of the lower link (660). Additionally, it can brake the carrier bag by friction with the wheel (100).

[0050] Here, in the wheel braking method, when the handle (200) is fully retracted, the handle column (300) pushes the flat plate (630) inside the housing (700) toward the ground. Then, the pushed-out flat plate (630) transmits pressure to the upper link (640). Here, the upper link (640), which is fixed by a hinge (650), transmits the pressure from the flat plate (630) as rotational force to the lower link (660), thereby causing the lower link (660) to move away from the wheel (100). Then, the contact brake (670) connected to the moved lower link (660) comes into contact with the wheel (100) and generates frictional force to brake the wheel (100).

[0051] Here, to aid in understanding the present invention, the direction in which the rubber part of the wheel (100) is viewed is defined as the front of the wheel (100), and the direction in which the wheel part of the wheel (100) is viewed is defined as the side of the wheel (100).

[0052] More specifically, referring to FIGS. 5c to 5f, when braking while moving, the wheel (100) can be braked from the side and front of the wheel (100) and various other positions of the wheel (100). Therefore, it is desirable for the contact brake (670) to be manufactured in a form that can brake by making contact regardless of how the wheel (100) is positioned.

[0053] FIGS. 6a and 6b are cross-sectional views in the Y direction according to FIG. 1 showing a fourth embodiment of a braking device for a carrier bag according to the present invention.

[0054] Referring to FIGS. 6a and 6b, in the case of a spring braking method, the braking unit (600) may include an arch brake plate (680) and a spring (690).

[0055] The arch brake plate (680) may be provided inside the housing (700). It may also come into contact with the handle column (300). Additionally, the part of the arch brake plate (680) that contacts the ground may be made of rubber, have a protruding structure, or utilize various other means to maximize friction. Furthermore, the arch brake plate (680) may be replaced if it wears out due to friction from the ground.

[0056] A spring (690) may be provided at the bottom of the arch brake plate (680). Additionally, the spring (690) must be able to maintain the arch brake plate (680) above the ground when the carrier bag moves. Therefore, an appropriate spring (690) can be selected according to the weight of the arch brake plate (680).

[0057] Here, in the spring braking method, when the handle is fully retracted, the handle column (300) presses the arch brake plate (680) inside the housing (700) and frictionally contacts the ground, thereby braking the carrier bag. Additionally, when the handle (200) is extended, the spring (690) installed at the bottom of the arch brake plate (680) can push the arch brake plate (680) away from the ground by means of elasticity.

[0058] As described above, the main technical concept of the present invention is to provide a product posture changing device. Furthermore, the embodiments described above with reference to the drawings are merely partial embodiments, and the scope of the present invention should be determined based on the patent claims. In addition, the scope of the present invention extends to various equivalent embodiments that can be derived.
