Description

Technical Field

[0001] The present invention relates to a shoe care device (shoe care equipment), and more specifically, to a shoe care device for managing and displaying shoes stored therein. Background Technology

[0002] Shoes can only be worn for a long time without losing their shape if they are properly stored. When shoes are stacked, their shape may be deformed. Generally, shoe cabinets are used to organize and store shoes.

[0003] In recent years, as a hobby or part of fintech, people have emerged who collect popular brand shoes, and shoe care devices configured to preserve and display shoes have been announced.

[0004] Korean Patent Publication No. 2017-0130045 (hereinafter referred to as "Prior Document") discloses a "Rotating 3D Image Lighting Device (Rotating Three-Dimensional Image Lighting Device)". The rotating 3D image lighting device includes a base, a transparent window, a first light-emitting element, a rotating platform, a cover plate, a second light-emitting element, and a control panel.

[0005] The base is located on the lower part of the turntable-type 3D image lighting device. The base is box-shaped. A drive motor is installed inside the base. The turntable is located above the base. The turntable rotates via the drive motor. The control panel controls the drive motor. When the drive motor is driven via the control panel, the product (hereinafter referred to as the "exhibit") placed on the upper surface of the turntable rotates together with the turntable.

[0006] The rotational force of the drive motor is transmitted to the rotating shaft of the turntable via a reducer, etc. Multiple bearings are connected to the base. The bearings fix the rotating shaft of the turntable in a constant position. The rotating shaft of the turntable is rotatably supported by multiple bearings.

[0007] However, according to existing technology, since the radial movement of the turntable's rotation axis is suppressed by multiple bearings, the state of the turntable's stable support for the exhibit may be affected by the position of the exhibit's center of gravity.

[0008] For example, according to existing literature, the levelness of the turntable is maintained by bearings that support the rotation axis of the turntable in the rotation axis direction and / or radial direction, such that when the center of gravity of the exhibit placed on the upper surface of the turntable is horizontally spaced from the rotation axis of the turntable, the force applied to the rollers and / or balls of the bearings in the rotation axis direction and / or radial direction of the turntable becomes uneven / deviation.

[0009] This is a major factor increasing the mechanical wear rate of bearings, and also contributes to the wear and fatigue failure of components connected to the bearings, making it difficult to continuously maintain the turntable's stable support of exhibits. In other words, the levelness of the turntable's upper surface is at high risk of being compromised by the aforementioned wear and fatigue failure.

[0010] Furthermore, when the forces applied to the rollers and / or balls of the bearing in the rotational axis and radial direction of the turntable are uneven / deviations, there is a risk that frictional forces may concentrate on some rollers and / or balls of the bearing, thereby hindering the smooth rotation of the turntable and causing irregular fluctuations in the rotational speed of the turntable.

[0011] Furthermore, according to existing literature, the turntable is supported only by the axis of rotation. Therefore, when the center of gravity of the exhibits placed on the upper surface of the turntable is horizontally spaced from the axis of rotation, the load on the exhibits causes micro-elastic bending deformation of the turntable. Since the turntable is used to display various exhibits for a long period of time, the aforementioned micro-elastic bending deformation can develop into permanent plastic deformation through the principle of fatigue failure.

[0012] According to existing technology, the turntable is illuminated by multiple light-emitting elements. In particular, when the turntable is made of a plastic material that is susceptible to light and heat, the light and heat from the light-emitting elements may accelerate plastic deformation due to fatigue failure.

[0013] The use of plastic materials should be pursued because they are beneficial for reducing the weight of devices and the capacity of motors. However, compared with metal materials, plastic materials are disadvantageous in terms of deformation caused by light, heat and load. Therefore, the use of plastic materials to manufacture components that are continuously subjected to light, heat and load requires a structural design that can prevent deformation.

[0014] Furthermore, according to existing technology, the rotation axis of the turntable is configured to be vertical via multiple bearings, making it difficult for the upper surface of the turntable to be perfectly horizontal.

[0015] For example, according to existing technology, the levelness of the turntable is maintained by bearings on the rotating shaft that supports the rotation axis of the turntable in the direction of rotation axis and / or radial direction. Therefore, when the bearings are installed in such a way that they are slightly spaced apart or tilted relative to the direction of gravity when manufacturing the turntable-type 3D image lighting device, the upper surface of the turntable can be tilted during manufacturing.

[0016] Therefore, in the development of shoe care devices with turntables, it is necessary to consider whether the turntable can rotate smoothly while maintaining its stability, regardless of the point on the upper side of the turntable where the load of the shoe is applied. These aspects need to be taken into account when developing shoe care devices. Summary of the Invention

[0021] The objective of this invention is to provide a shoe care device that can prevent the turntable from undergoing plastic deformation due to fatigue failure, even when the center of gravity of the shoe is separated from the center of the turntable.

[0023] The objective of this invention is to provide a shoe care device that can keep the upper surface of a turntable completely level, even during manufacturing and even when shoes are displayed for extended periods of time.

[0024] Technical solution

[0025] The shoe care device described in this application may include a main body, a movable main body, and a blowing section.

[0026] The main body and the moving body can together form a containing space. The containing space can hold the shoe.

[0027] The blowing section can be configured to circulate air within the containment space.

[0028] The moving body may include a base, a turntable, and multiple rotating balls.

[0029] The base can be slidably attached to the body to open and close the receiving space.

[0030] The turntable can be attached to the base so that it can rotate about a vertical axis. The turntable and the base can together form the lower surface of the receiving space.

[0031] The rotating ball can be rotatably attached to the base. The rotating ball can make point contact with the bottom surface of the turntable and can support the load of the turntable.

[0032] The base may include a first base surface and a second base surface.

[0033] The first base surface can be positioned along the perimeter of the turntable. The first base surface, together with the upper surface of the turntable, can form the lower surface of the receiving space.

[0034] The second base surface can be positioned below the turntable. The rotating ball can protrude above the second base surface.

[0035] A rotating sphere is rotationally symmetrical about a vertical axis.

[0036] A spinning ball can include a first spinning ball and a second spinning ball.

[0037] Multiple first rotating spheres can be set. The first rotating spheres can be arranged along the circumferential direction at a first distance from the vertical axis.

[0038] Multiple second rotating spheres can be set. The second rotating spheres can be arranged along the circumferential direction at a second distance from the vertical axis, which is longer than the first distance.

[0039] The number of first-spinning balls can be greater than the number of second-spinning balls.

[0040] The base may have multiple sockets to which a rotating ball can be rotatably connected.

[0041] Each socket may include a receiving body and a restraining protrusion.

[0042] The receiving body can form a hemispherical groove to at least accommodate the lower part of the rotating sphere.

[0043] Multiple constraint protrusions can be set. The constraint protrusions can extend upward from the edge of the hemispherical groove to prevent the rotating ball from separating.

[0044] The diameter of the hemispherical groove can be larger than the diameter of the rotating sphere.

[0045] The top of the rotating ball can be higher than the top of the constraint protrusion.

[0046] The constraint protrusion may have a contact surface to prevent the spinning ball from separating.

[0047] The contact surface can have the same curvature as the inner surface of the hemispherical groove.

[0048] Multiple through holes can be formed in the receiving body to reduce friction between the receiving body and the rotating ball.

[0049] The constraint protrusions and through holes can be rotate symmetrical about the center of the hemispherical groove.

[0050] The through hole can be positioned below the constraint protrusion.

[0051] The constraint protrusion can have a contact surface that prevents the rotating ball from separating.

[0052] One of the constraint protrusions and the other of the constraint protrusions can be positioned at the same radius around the vertical axis and the center of the hemispherical groove.

[0053] The subject can include the following subjects.

[0054] The lower body can be positioned below the receiving space. The lower body can have a lower body recess with an open front side.

[0055] The moving body may include a motor.

[0056] The motor can be installed in the lower body recess and connected to the turntable to apply rotational force.

[0057] Beneficial effects

[0058] In the shoe care device according to an embodiment of the present invention, since the rotating ball makes point contact with the receiving body and the turntable and rolls using the kinetic energy of the turntable, the frictional resistance between the turntable and the rotating ball can be reduced, thereby reducing the kinetic energy loss of the motor. Therefore, a motor with a smaller capacity than existing motors can be used to rotate the turntable. Thus, the size and weight of the shoe care device can be reduced by decreasing the motor capacity.

[0059] In the shoe care device according to an embodiment of the present invention, the rotating shaft of the motor can be simply inserted into a boss on the bottom surface of the turntable to transmit rotational force, and a rotating ball can support the load of the turntable and the shoe. When the turntable rotates, the rotating ball can rotate through the kinetic energy of the bottom surface of the turntable, and can distribute and support the load of the turntable and the shoe. Therefore, even when the center of gravity of the shoe is horizontally spaced from the rotation axis of the turntable, elastic bending deformation of the turntable can be prevented. Furthermore, even when the shoe care device is used for a long period of time, wear and fatigue failure of the turntable due to the load of the shoe can be minimized, and the upper surface of the turntable can remain flat for a long period of time.

[0060] In the shoe care device according to an embodiment of the present invention, the rotating balls can all be formed into a perfectly spherical shape. Therefore, the height of the rotating balls can always be constant relative to the second base surface. Furthermore, the height of the upper surface of the rotating turntable can always be constant relative to the first base surface. Therefore, the shoe can rotate at a constant height, and the display effect of the shoe can be improved.

[0061] In a shoe care device according to an embodiment of the present invention, multiple through holes can be formed in the receiving body. Forming through holes reduces the area of ​​point contact between the inner surface of the receiving body and the rotating ball. Therefore, friction between the receiving body and the rotating ball can be reduced, and kinetic energy loss of the motor can be minimized. Thus, a motor with a smaller capacity than existing motors can be used to rotate the turntable. Furthermore, the size and weight of the shoe care device can be reduced by decreasing the motor capacity.

[0062] In the shoe care device according to an embodiment of the present invention, the elastic deformation of the receiving body can be facilitated by forming through holes. Therefore, when a shoe is placed on the turntable, the impact force applied to the turntable can be dissipated through the elastic deformation of the receiving body. Thus, the possibility of damage to the turntable and the rotating ball due to the impact force applied to the turntable when the shoe is placed on it can be reduced.

[0063] In a shoe care device according to an embodiment of the present invention, during the reciprocating rotation of the turntable, a pair of first constraint protrusions can be positioned in the direction of transmission of kinetic energy applied from the turntable to the rotating ball. Therefore, the pair of first constraint protrusions can firmly prevent the rotating ball from separating due to the kinetic energy applied from the turntable to the rotating ball.

[0064] In a shoe care device according to an embodiment of the invention, one of a pair of second constraint protrusions can be positioned along the direction of centrifugal force transmission during the reciprocating rotation of the turntable. Therefore, the pair of second constraint protrusions can prevent the rotating ball from separating due to the centrifugal force acting on the shoe during the rotation of the turntable.

[0065] In the shoe care device according to an embodiment of the present invention, the rotating ball is rotationally symmetrical about a vertical axis. Therefore, the rotating ball can be distributed and support the load of the turntable and the shoe in a rotationally symmetrical manner about the vertical axis. Thus, the load of the turntable and the shoe can be distributed and applied to the turntable housing in a rotationally symmetrical manner about the vertical axis. Therefore, even when the center of gravity of the shoe is horizontally spaced from the turntable's rotation axis, elastic bending deformation of the turntable can be prevented. Therefore, even with prolonged use of the shoe care device, wear and fatigue failure of the turntable due to the load of the shoe can be minimized, and the upper surface of the turntable can remain flat for extended periods.

[0066] In the shoe care device according to an embodiment of the present invention, since more rotating balls are positioned at a first distance closer to the rotation axis of the turntable than a second distance, the weight of the shoe can be evenly distributed on the first and second rotating balls. Therefore, even when the shoe care device is used for a long period of time, wear and fatigue failure of the turntable, rotating balls, and base caused by the load of the shoe can be minimized, and thus the upper surface of the turntable can remain flat for a long period of time.

[0091] Preferred embodiments of the invention will be described in detail below with reference to the accompanying drawings. However, in order to clarify the subject matter of the invention, descriptions of known features or configurations will be omitted.

[0092] When shoes are directly exposed to dust, water, heat and / or sunlight, the shoe's fiber materials can deteriorate over time, and the shoe's color and shape may change.

[0093] To preserve shoes for an extended period in their original condition (e.g., the condition when purchased or as clean shoes), they should not be exposed to too much light and should be stored in a place that is neither too cold nor too hot. Furthermore, shoes need to be stored in a place that appropriately maintains temperature and humidity.

[0094] Shoes made of leather or suede are prone to discoloration or mold growth, so they should be stored in an environment with appropriate temperature and humidity. Camphor balls, obtained by curing insecticides and fragrances, have a distinctive chemical odor that is difficult to remove, as this odor seeps into the shoes when they are stored with them.

[0095] In addition, when shoes are stacked in layers, the shape of the shoes may change due to the applied load.

[0096] Meanwhile, as mentioned above, in recent years, there has been an increase in users who collect popular brand shoes as a hobby or part of fintech, and shoe care and shoe display have become important needs for users.

[0097] Taking these points into consideration, the shoe care device according to an embodiment of the present invention is configured to: safely store shoes, establish and regulate the environment required for each shoe (e.g., a predetermined range of temperature, humidity, etc.), effectively display the shoes, and improve the user's ease of use.

[0098] In embodiments of the present invention, the first direction X, the second direction Y, and the third direction Z can be directions that are orthogonal to each other.

[0099] The first direction X and the second direction Y can be parallel to the horizontal direction, and the third direction Z can be parallel to the vertical direction. When the first direction X is parallel to the front-back direction, the second direction Y can be parallel to the left-right direction.

[0100] In describing embodiments of the present invention, the first direction X, the second direction Y, and the third direction Z can be understood as the forward direction, the left direction, and the upward direction, respectively, unless otherwise specified.

[0101] Figure 1a This is a perspective view showing a shoe care device 1 according to an embodiment of the present invention. Figure 1a The image shows the shoe care device 1 in a closed state, with its internal space (hereinafter referred to as "accommodation space 10") closed. Figure 1b This shows that shoe S is stored in Figure 1a A three-dimensional view of the state of the shoe care device 1 within its housing space 10.

[0102] Figure 2a It is shown that Figure 1aA perspective view of the shoe care device 1 with its storage space 10 open. Figure 2b It shows the view from another direction. Figure 2a A perspective view of a shoe care device.

[0103] like Figure 1a and Figure 1b As shown, the shoe care device 1 according to this embodiment is configured to include a main body 100 and a movable main body 200.

[0104] The main body 100 and the movable body 200 together form a receiving space 10 for receiving the shoe S. The main body 100 and the movable body 200 are connected to move relative to each other. The movable body 200 can be connected to the main body 100 to move reciprocally in the horizontal direction.

[0105] Figure 1a The shoe care device 1 shown can be as follows: Figure 2a The shoe care device shown is modified in the same way. That is, the movable body 200 can be slidably moved relative to the body 100 in the first direction X, and the shoe care device 1 changes from the closed state to the open state, thereby opening the receiving space 10.

[0106] Figure 2a The shoe care device 1 shown can be used again as follows Figure 1a The shoe care device 1 shown is modified in the same way. That is, the movable body 200 can slide relative to the body 100 in a direction opposite to the first direction X, and the shoe care device 1 changes from an open state to a closed state, thereby closing the receiving space 10.

[0107] Therefore, in the shoe care device 1 according to an embodiment of the present invention, the movable body 200 can move relative to the body 100 in the first direction X or in a direction opposite to the first direction X, and can move back and forth in the front-back direction.

[0108] When the containing space 10 is closed, it can be sealed from the outside air. Therefore, when the shoe S is contained in the containing space 10 and the containing space 10 is closed, the contact between the shoe S and dust and moisture from the outside air can be interrupted.

[0109] The main body 100 can form the upper surface and the rear surface of the accommodating space 10.

[0110] The movable body 200 can form a front surface, a lower surface, and two side surfaces of the accommodating space 10.

[0111] The receiving space 10 can be formed in the form of a hexahedron. However, the receiving space 10 of the shoe care device 1 according to an embodiment of the present invention is not limited to this shape, and can be configured in various three-dimensional shapes.

[0112] The main body 100 and the movable body 200 can form the overall appearance of the shoe care device 1. The appearance of the shoe care device 1 can be configured in a hexahedral form. That is, in the state where the main body 100 and the movable body 200 are connected to each other and the receiving space 10 is closed, the appearance of the shoe care device 1 can be configured in a hexahedral form. However, the shoe care device 1 according to the embodiment of the present invention is not limited to this shape, but can be configured in various three-dimensional shapes.

[0113] The main body 100 may include an upper main body 130, a middle main body 120 and a lower main body 110.

[0114] The upper body 130 is positioned above the receiving space 10. The upper body 130 forms the upper surface of the receiving space 10. The upper body 130 can form the uppermost part of the shoe care device 1. The upper surface of the upper body 130 can form a flat surface along a substantially horizontal surface. When multiple shoe care devices 1 are provided, any one shoe care device can be placed on the upper surface of the upper body 130 of another shoe care device 1, and the shoe care devices 1 can be stacked on top of each other.

[0115] The lower body 110 is positioned below the receiving space 10. The lower body 110 can form the lowest part of the shoe care device 1. The lower body 110 can form the bottom part of the shoe care device 1.

[0116] The intermediate body 120 is positioned behind the receiving space 10. The intermediate body 120 forms the rear surface of the receiving space 10. The intermediate body 120 can connect to the upper body 130 and the lower body 110 behind the receiving space 10. The intermediate body 120 can form the rear wall surface of the shoe care device 1.

[0117] The main body 100 is configured to include an upper body 130, a middle body 120 and a lower body 110, and as a result, the main body 100 can form a substantially “C” shape in a side view.

[0118] As described above, the moving body 200 is configured to move forward and backward relative to the body 100. The moving body 200 may include a base 220, a transparent window 210, and a turntable 230.

[0119] The base 220 can be coupled to the lower body 110 to be slidably movable in a first direction X. The base 220 can form the bottom portion of the movable body 200. The base 220 can be positioned on the upper side of the lower body 110. The bottom surface of the base 220 can be positioned to be in close contact with or near the upper surface of the lower body 110.

[0120] The transparent window 210 can be formed to extend upward from the base 220. The transparent window 210 can form the front surface and two side surfaces (left and right surfaces) of the receiving space 10. The transparent window 210 can be made of transparent or translucent material.

[0121] Light from both inside and outside the containment space 10 can pass through the transparent window 210. The transparent window 210 can be made of a weather-resistant material to prevent discoloration. The transparent window 210 can be made of polymethyl methacrylate (PMMA), which is weather-resistant and scratch-resistant.

[0122] The transparent window 210 can prevent light beams with a predetermined wavelength from being introduced into the receiving space 10. As an example, the transparent window 210 can be configured to block ultraviolet rays. Ultraviolet rays, which are electromagnetic waves with wavelengths shorter than visible light (10 nm to 397 nm), are light with strong chemical effects and can cause sunburn or discoloration.

[0123] As an example, a UV-protective film can be attached to the inner or outer surface of the transparent window 210. Alternatively, the inner or outer surface of the transparent window 210 can be UV-coated with a UV-protective agent.

[0124] The transparent window 210 includes a first window 211, a second window 212, and a third window 213. The first window 211 can form the front surface of the receiving space 10. The second window 212 can form the left surface of the receiving space 10. The third window 213 can form the right surface of the receiving space 10.

[0125] With the shoe S contained within the housing space 10, the user can observe the shoe S through the transparent window 210. Therefore, the shoe care device 1 can be used as a device that can display the shoe S while storing and caring for it.

[0126] like Figure 1a and Figure 1b As shown, with the movable body 200 positioned relatively at the rearmost side, the receiving space 10 can be sealed from the outside air. In this case, the receiving space 10 can be formed in a hexahedral form. In this case, the movable body 200 can be present in the first position, and the shoe care device 1 is in the closed state.

[0127] like Figure 2a and Figure 2b As shown, the receiving space 10 can be opened when the moving body 200 is moving along the first direction X. In this case, the upper portion of the first window 211 is spaced forward from the front surface of the upper body 130 in the first direction X to form a gap (hereinafter referred to as the "first gap").

[0128] In this configuration, the second window 212 is spaced forward from the left side of the intermediate body 120 in the first direction X to form a gap (hereinafter referred to as the "second gap"). The third window 213 is spaced forward from the right side of the intermediate body 120 in the first direction X to form a gap (hereinafter referred to as the "third gap").

[0129] In a state in which the moving body 200 moves as far as possible along the first direction X, that is, in a state in which the moving body 200 is relatively positioned at the foremost side, the moving body 200 may exist in the second position, and the shoe care device 1 may be in the open state.

[0130] The user can place the shoe S into the receiving space 10 or remove the shoe S from the receiving space 10 through the first gap. The information piece 500 can be attached to the inner surface of the intermediate body 120 or separated from the inner surface of the intermediate body 120.

[0131] The turntable 230 can form an upper surface on which the shoe S is placed. The upper surface of the turntable 230 can have a circular shape. The turntable 230 and the base 220 can together form the lower surface of the receiving space 10.

[0132] The turntable 230 can be rotatably connected to the base 220 about a vertical axis (i.e., an axis parallel to the third direction Z).

[0133] To enable the turntable 230 to rotate, a motor 290 can be installed in the moving body 200. The motor 290 can be connected to the base 220. The turntable 230 can rotate in coordination with the rotation of the motor 290. The rotational force of the motor 290 can be transmitted to the turntable 230 through a reducer. The motor 290 can rotate unidirectionally or bidirectionally in a reciprocating motion.

[0134] With turntable 230 set, the shoe S can rotate within the accommodating space 10, or the display effect of the shoe S can be enhanced.

[0135] The shoe care device 1 may include an operation button 610 and a controller 600. The operation button 610 may be formed in the main body 100. As an example, the operation button 610 may be formed on the front surface of the upper main body 130.

[0136] When the user operates the operation button 610, the turntable 230 can rotate or stop. The user operates the operation button 610 to adjust the rotation speed of the turntable 230. The user can input the rotation time of the turntable 230 into the controller 600 through the operation button 610.

[0137] The user operates the control button 610 to rotate the turntable 230 by a predetermined angle. With the receiving space 10 open, the user can place the shoe S on the upper surface of the turntable 230 by holding any part of the shoe S (heel top, lining, tongue, etc.). The user then operates the control button 610 to rotate the turntable 230 by the predetermined angle.

[0138] As an example, the user manipulates the operation button 610, causing the turntable 230 to rotate at a predetermined angle, so that the front-back direction of the shoe S is aligned with the first direction X. Alternatively, the user manipulates the operation button 610, causing the turntable 230 to rotate at a predetermined angle, so that the front-back direction of the shoe S forms a predetermined angle with the first direction X.

[0139] Therefore, even if the user places the shoe S on the upper surface of the turntable 230 while gripping any part of the shoe S, the shoe S can be placed (displaced) in the direction desired by the user.

[0140] A sensor (not shown) for sensing the movement of the moving body 200 may be provided in the body 100. When the accommodating space 10 is closed, the controller 600 can rotate the turntable 230 via the sensor signal.

[0141] A load sensor (not shown) may be provided in the base 220. The load sensor can automatically measure the load of the shoe S placed on the turntable 230. The rotational speed of the turntable 230 based on the measurement value of the load sensor can be set in the controller 600. Alternatively, the user can input the rotational speed of the turntable 230 based on the measurement value of the load sensor into the controller 600 via the operation button 610.

[0142] A camera (not shown) may be installed in the shoe care device 1. The camera can automatically photograph the shoes S placed on the turntable 230. The controller 600 can identify the shape, size, and / or type of the shoes S through the images captured by the camera.

[0143] The rotational speed of the turntable 230, based on the shape, size, and / or type of the shoe S, can be set in the controller 600. Alternatively, the user can input the rotational speed of the turntable 230, based on the shape, size, and / or type of the shoe S, into the controller 600 via the operation button 610.

[0144] The shoe care device 1 may include an operation sensor. The operation sensor can detect the user's approach. The turntable 230 can rotate or stop based on the sensing signal from the operation sensor.

[0145] Figure 3a It is shown Figure 1b A side view of the shoe care device 1 in use. Figure 3a The state of the shoe S in the illumination accommodating space 10 is shown.

[0146] Figure 3b It is shown Figure 1b A front view of the shoe care device 1 in use. Figure 3b The airflow within the containment space 10 is shown.

[0147] The shoe care device 1 according to an embodiment of the present invention may include a first lighting element 410. The first lighting element 410 may be disposed in the upper body 130.

[0148] like Figure 3a As shown, the first illumination element 410 can illuminate the receiving space 10. The first illumination element 410 may include a light source 411 and a lens 414.

[0149] Light source 411 can concentrate light onto the upper surface of the turntable 230 on which the shoe S is placed. The light from light source 411 can concentrate light onto the shoe S placed on the upper surface of the turntable 230. When the first illumination element 410 rotates, the image of the shoe S stored in the receiving space 10 can be changed by the light from light source 411.

[0150] Light from light source 411 can pass through lens 414 and illuminate receiving space 10. An anti-ultraviolet film can be attached to lens 414, or an anti-ultraviolet agent can be coated onto lens 414 to block ultraviolet rays.

[0151] When the user manipulates the operation button 610, the light source 411 can be turned on or off. The user can input the operating time of the light source 411 into the controller 600 through the operation button 610. The user manipulates the operation button 610 to adjust the operating time of the light source 411.

[0152] Alternatively, the light source 411 can be turned on or off by operating the sensor's sensing signal. The controller 600 can turn the light source on or off by operating the sensor's signal.

[0153] Alternatively, the light source 411 can be turned on or off by a sensing signal from a sensor. When the containment space 10 is closed, the controller 600 can turn the light source on or off by a sensor signal.

[0154] Alternatively, the operating time and operating mode of the light source based on the measurement value of the load sensor can be set in the controller 600. The user can input the operating time and operating mode of the light source 411 based on the measurement value of the load sensor into the controller 600 via the operation button 610.

[0155] Alternatively, the operating time and operating mode of the light source 411 according to the shape, size, and / or type of the shoe S can be set in the controller 600. The user can input the operating time and operating mode of the light source 411 according to the shape, size, and / or type of the shoe S into the controller 600 via the operation button 610.

[0156] The light source 411 can be configured to change the color of the light. As an example, the light source 411 can be composed of red, green, blue, and white (RGBW) LEDs. The controller 600 can control the current applied to the red (R) LED, green (G) LED, blue (B) LED, and white (W) LED. When the controller 600 controls the current applied to the RGBW LEDs, the aesthetics and color perception of the shoe S stored in the receiving space 10 can be changed differently. The user can input the current mode applied to the RGBW LEDs into the controller 600 via the operation button 610.

[0157] Figure 4 This is a perspective view showing the bottom surface of the movable body 200 in the shoe care device 1 according to an embodiment of the present invention. Figure 5a This is a perspective view showing the movable body 200 of the shoe care device 1 according to an embodiment of the present invention.

[0158] The main body 100 may include a lower body 110 located below the receiving space 10 and having a lower body recess 119 having an open front side (see...). Figure 2b ).

[0159] The movable body 200 may include: a base 220 slidably connected to the lower body 110; a turntable 230 connected to the base 220 to rotate about a vertical axis 231 and forming the lower surface of the receiving space 10 together with the base 220; and a motor 290 disposed in the lower body recess 119 and connected to the turntable 230 to apply rotational force to the turntable 230.

[0160] The extension of the vertical axis 231 can be parallel to the first direction X, which is the horizontal direction, and can be located within the reference plane RP, which is the vertical plane.

[0161] In other words, a lower body groove 119 (which is recessed downward and has an open front side) can be formed in the central portion of the lower body 110 to prevent interference with the body 100 during the sliding of the moving body 200.

[0162] In particular, in order to rotate the turntable 230 which is connected to the base 220 of the moving body 200, the motor 290 also needs to be connected to the base 220, and for aesthetic reasons, the motor 290 can preferably be positioned below the base 220.

[0163] Therefore, when the motor 290 is located below the base 220, it is more preferable to locate the motor 290 in the lower body groove 119, so that the motor 290 does not interfere with the body 100 when the moving body 200 slides.

[0164] Therefore, in the shoe care device 1 according to this embodiment, a motor 290 that applies rotational force to the turntable 230 is provided in a lower body groove 119 formed in the lower body 110, so that the motor 290 can be prevented from interfering with the body 100 during the sliding of the moving body 200.

[0165] The shoe care device 1 according to an embodiment of the present invention may further include: a power supply disposed in a portion of the lower body 110 other than the lower body recess 119, for supplying power to the motor 290; and a cable for electrically connecting the power supply to the motor 290.

[0166] Figure 5b This is an exploded perspective view showing the movable body 200 of the shoe care device 1 according to an embodiment of the present invention. Figure 5c yes Figure 5a The diagram shows the turntable 230 separated from the moving body 200.

[0167] The movable body 200 and the main body 100 together form the receiving space 10. The movable body 200 can be movably connected to the main body 100 between a first position and a second position. The second position is the position in front of the first position. The movable body 200 can be connected to the main body 100 so that it can move forward and backward relative to the main body 100.

[0168] When the moving body 200 is in the first position, the accommodating space 10 is closed, and when the moving body is in the second position, the accommodating space 10 is opened.

[0169] When the movable body 200 is in the second position, the receiving space 10 of the shoe care device 1 opens on the upper, left and right sides.

[0170] When the moving body 200 moves forward and backward relative to the body 100, the moving body 200 can be supported by the lower body 110 and the upper body 130.

[0171] When the movable body 200 is in the first position, the upper left and right sides and the lower left and right sides of the movable body 200 are supported by the main body 100. When the movable body 200 is in the second position, the upper left and right sides and the lower left and right sides of the movable body 200 can also be supported by the main body 100.

[0172] In embodiments of the present invention, the transparent window 210 can be integrally configured. That is, the corresponding parts constituting the transparent window 210 are not configured to be connected or fixed to each other by fastening devices (e.g., brackets, clamps, bolts, adhesives, etc.), but the transparent window 210 can be configured as a single body from the time of manufacture. All parts constituting the transparent window 210 can be made of the same material. All parts constituting the transparent window 210 can be configured to have the same physical properties.

[0173] In the shoe care device 1 according to an embodiment of the present invention, the transparent window 210 can be formed by injection molding.

[0174] Most or all of the transparent window 210 can be configured to be transparent.

[0175] The transparent window 210 can be configured by a combination of plates that form separate planes. The plates constituting the transparent window 210 are connected to each other. The plates constituting the transparent window 210 are connected to each other at corresponding corners. The portions of the plates connected in the transparent window 210 can be curved, curved, or flat.

[0176] The transparent window 210 can be made of polymethyl methacrylate (PMMA).

[0177] The transparent window 210 includes a first window 211, a second window 212, and a third window 213. Each of the first window 211, the second window 212, and the third window 213 is configured to be transparent. Each of the first window 211, the second window 212, and the third window 213 can be configured as a flat panel. Each of the first window 211, the second window 212, and the third window 213 can be configured as a square panel. The vertical height of the corresponding windows in the first window 211, the second window 212, and the third window 213 can be the same or approximately the same as each other.

[0178] The first window 211 forms the front surface of the shoe care device 1, the second window 212 forms the left surface of the shoe care device 1, and the third window 213 forms the right surface of the shoe care device 1. The second window 212 extends rearward from the left end of the first window 211, and the third window 213 extends rearward from the right end.

[0179] The first window 211 forms the front surface of the transparent window 210, the second window 212 forms the left surface of the transparent window 210, and the third window 213 forms the right surface of the transparent window 210. The inner and outer surfaces of the first window 211 can form surfaces orthogonal to a first direction. The inner and outer surfaces of the second window 212 can form surfaces orthogonal to a second direction. The inner and outer surfaces of the third window 213 can form surfaces orthogonal to a second direction.

[0180] The inner surface of the first window 211 forms the front surface of the receiving space 10. The inner surface of the second window 212 forms the left surface of the receiving space 10. The inner surface of the third window 213 forms the right surface of the receiving space 10.

[0181] The transparent window 210 includes a first window 211, a second window 212, and a third window 213, and as a result, the transparent window 210 can be configured in a substantially C-shape (or...) on a plan view. (shape, Π shape or ┏┓ shape).

[0182] The transparent window 210 can be configured symmetrically around the reference plane RP. The second window 212 and the third window 213 can be configured symmetrically around the reference plane RP.

[0183] In the shoe care device 1, the upper body 130 and the first window 211 can be opened / closed to each other, the middle body 120 and the second window 212 can be opened / closed to each other, and the middle body 120 and the third window 213 can be opened / closed to each other.

[0184] The lower sides of the second window 212 and the third window 213 can be supported on the lower body 110.

[0185] The upper side of the second window 212 and the upper side of the third window 213 can be supported on the upper body 130.

[0186] In the shoe care device 1 according to an embodiment of the present invention, the transparent window 210 can be integrally formed. Furthermore, the transparent window 210 can cover most of the front, left, and right surfaces of the shoe care device 1.

[0187] The area of ​​the first window 211 can be configured to correspond to the area of ​​the front surface of the receiving space 10. The area of ​​the second window 212 can be configured to correspond to the area of ​​the left surface of the receiving space 10. The area of ​​the third window 213 can be configured to correspond to the area of ​​the right surface of the receiving space 10.

[0188] According to an embodiment of the present invention, the area of ​​the transparent window 210 can be maximized, so that the shoe S contained in the accommodating space 10 can be unobstructed and can be well observed from all front, left and right sides, thereby improving the display effect of the shoe.

[0189] Unlike the embodiments of the present invention, when the transparent window 210 is formed only on the front surface of the shoe care device 1, the shoe S may not be visible on the left or right side of the shoe care device, and the display effect of the shoe may not be fully displayed.

[0190] Unlike embodiments of the present invention, if the first window 211 and the second window 212 are not integrally configured (and if the first window 211 and the third window 213 are not integrally configured), the user can observe the boundary between the first window 211 and the second window 212 (and the boundary between the first window 211 and the third window 213), and this boundary can visually obstruct the shoes within the receiving space 10, reducing the display effect of the shoes and potentially decreasing user satisfaction. Furthermore, gaps may form between the boundaries, and foreign objects may be introduced into the receiving space 10 through these gaps.

[0191] The transparent window 210 includes a first curved surface portion 214 and a second curved surface portion 215. Each of the first curved surface portion 214 and the second curved surface portion 215 forms a vertical corner portion of the transparent window 210.

[0192] The first curved surface portion 214 is the portion connecting the first window 211 and the second window 212. The cross-section of the first curved surface portion 214 can be configured consistently in the vertical direction (or a third direction). The first curved surface portion 214 is configured with a curved surface structure. Each of the outer and inner surfaces of the first curved surface portion 214 is configured as a curved surface protruding outward from the transparent window 210.

[0193] The first window 211 and the first curved surface portion 214 can be configured such that the radius of curvature changes continuously. Furthermore, the second window 212 and the first curved surface portion 214 can be configured such that the radius of curvature changes continuously. That is, on the inner and outer surfaces of the portions connecting the first window 211 to the first curved surface portion 214 and the second window 212, the radius of curvature cannot change discontinuously, but a curved surface may not be formed.

[0194] When the inner and outer surfaces of the first window 211 and the second window 212 are configured by planes in the transparent window 210, and the transparent window 210 is configured to include a first curved surface portion 214, the radii of curvature of the inner and outer surfaces of the first curved surface portion 214 can be configured to be from 1 mm to 50 mm.

[0195] The transparent window 210 is configured to include a first curved portion 214, and as a result, the shoe S inside the accommodating space 10 can be fully observed by the user without being visually blocked by the first curved portion 214.

[0196] Furthermore, the first curved surface portion 214 is configured as described above, and as a result, deformation of the shoe S inside the receiving space 10 can be prevented or minimized through the first curved surface portion 214, the portion connecting the first curved surface portion 214 and the first window 211, and the portion connecting the first curved surface portion 214 and the second window 212.

[0197] The second curved surface portion 215 is the portion connecting the first window 211 and the third window 213. The cross-section of the second curved surface portion 215 can be configured consistently in the vertical direction (or the third direction). The second curved surface portion 215 is configured with a curved surface structure. Each of the outer and inner surfaces of the second curved surface portion 215 is configured as a curved surface protruding outward from the transparent window 210.

[0198] The first window 211 and the second curved surface portion 215 can be configured such that the radius of curvature changes continuously. Furthermore, the third window 213 and the second curved surface portion 215 can be configured such that the radius of curvature changes continuously. That is, on the inner and outer surfaces of the portions connecting the first window 211 to the second curved surface portion 215 and the third window 213, the radius of curvature cannot change discontinuously, but a curved surface may not be formed.

[0199] When the inner and outer surfaces of the first window 211 and the third window 213 are configured by planes in the transparent window 210, and the transparent window 210 is configured to include a second curved surface portion 215, the radii of curvature of the inner and outer surfaces of the first curved surface portion 214 can be configured from 1 mm to 50 mm.

[0200] The transparent window 210 is configured to include a second curved portion 215, and as a result, the shoe S inside the accommodating space 10 can be fully observed by the user without being visually blocked by the second curved portion 215.

[0201] Furthermore, the second curved surface portion 215 is configured as described above, and as a result, deformation of the shoe S inside the accommodating space 10 can be prevented or minimized through the second curved surface portion 215, the portion connecting the second curved surface portion 215 and the first window 211, and the portion connecting the second curved surface portion 215 and the third window 213.

[0202] As described above, according to the embodiment of the present invention, no gaps are formed at the connection portions of the first window 211 and the second window 212, and at the connection portions of the first window 211 and the third window 213. The aesthetics at these portions are excellent, and foreign objects such as dust can be prevented from passing through these portions and entering the receiving space 10. Furthermore, the shoe S is not visually obstructed; it can be observed even through the connection portions of the first window 211 and the second window 212, and at the connection portions of the first window 211 and the third window 213. Moreover, the air in the receiving space 10 can be controlled, and the shoe S can be fully exposed on the front, left, and right sides of the shoe care device 1, thereby effectively achieving both shoe management and shoe display.

[0203] Furthermore, with the shoe care device 1 according to an embodiment of the present invention, even if multiple shoe care devices 1 are stacked vertically or arranged horizontally, each shoe care device 1 can operate smoothly, and each shoe S contained in each shoe care device 1 can be visually exposed.

[0204] The transparent window 210 integrally disposed in the shoe care device 1 according to an embodiment of the present invention is made of polymethyl methacrylate (PMMA) and includes a first curved surface portion 214 and a second curved surface portion 215. As a result, the transparent window 210 itself can be aesthetically pleasing, and the shoe care device 1 can be easily assembled. Furthermore, discoloration of the transparent window 210 can be prevented, and a solid transparent window 210 can be formed. Moreover, when an external user observes the shoe S housed in the shoe care device 1 through the transparent window 210, the entire shape of the shoe is not divided but observed as a whole, and deformation is prevented.

[0205] The base 220 is fixedly connected to the lower side of the transparent window 210 to form the lower part of the movable body 200. The base 220 can be configured as a flat shape in the horizontal direction. The base 220 can also be configured as a square shape in a plan view.

[0206] The base 220 can be configured such that the shoe S is placed on the upper side of the base 220. The upper surface 220a of the base 220 can be configured to be substantially square.

[0207] The upper surface 220a of the base 220 can be positioned in the receiving space 10 along the periphery of the turntable 230. The top surface 220a of the base 220 can form the lower surface of the receiving space 10 together with the upper surface of the turntable 230. The top surface 220a of the base 220 positioned in the receiving space 10 along the periphery of the turntable 230 will be referred to as the first base surface 220a.

[0208] The base 220 is positioned on the upper side of the lower body 110. The upper surface 220a of the base 220 is positioned on the upper side of the lower body 110. The base 220 is connected to the lower body 110 and is movable forward and backward.

[0209] The movable body 200 can be configured to include a turntable 230. The turntable 230 is rotatably connected to the upper side of the base 220 about a vertical axis of rotation 231. The turntable 230 is configured in the form of a circular plate. The upper surface of the turntable 230 can be configured to be parallel to a first direction X and a second direction Y.

[0210] The vertical rotation axis 231 can refer to the rotation shaft 231 of the motor 290. A boss can be formed on the bottom surface of the turntable 230 for the rotation shaft 231 of the motor 290 to be inserted. To transmit rotational force from the motor 290 to the turntable 230, the rotation shaft 231 of the motor 290 and the boss can be connected to each other by a key. Keyways can be formed in the rotation shaft 231 of the motor 290 and the boss. Alternatively, to transmit rotational force from the motor 290 to the turntable 230, the rotation shaft 231 of the motor 290 and the boss can be formed in an asymmetrical shape relative to the center of the rotation shaft 231.

[0211] The base 220 may have a turntable receiving portion 221 for accommodating the turntable 230. The turntable receiving portion 221 may be formed in a concave shape at the center of the upper surface 220a of the base 220.

[0212] Therefore, the height of the upper surface (hereinafter referred to as the "second base surface") 221a of the turntable housing 221 is configured to be slightly lower than the height of the upper surface 220a of the base 220 other than the turntable housing 221.

[0213] In the plan view, the turntable receiving portion 221 can be formed in a circular shape around the vertical rotation axis 231. Therefore, the second base surface 221a can be circular. The shape and size of the turntable receiving portion 221 are configured to correspond to the shape and size of the turntable 230.

[0214] The upper surface 220a of the base 220 (excluding the turntable receiving portion 221) can be formed to have a height corresponding to or matching the height of the upper surface of the turntable 230 while the turntable 230 is connected to the base 220. The second base surface 221a can be positioned below the turntable 230.

[0215] As the transparent window 210 and the base 220 move forward relative to the main body 100, the shoe can be placed on the base 220 or removed from the base 220 through the space between the upper main body 130 and the first window 211.

[0216] Furthermore, in this configuration, the user can access the shoe or upper space through the space between the intermediate body 120 and the second window 212 or the space between the intermediate body 120 and the third window 213. Additionally, in this configuration, the user can easily access the inner surface of each of the lower body 110, the intermediate body 120, and the upper body 130 (see [link to relevant documentation]). Figure 2a and Figure 2b ).

[0217] According to an embodiment of the present invention, it is convenient to remove shoes from the shoe care device 1 and insert shoes into the shoe care device 1, and positioning shoes is convenient.

[0218] As described above, the moving body 200 is configured to include a turntable 230 in the shoe care device 1 according to an embodiment of the present invention. Therefore, the shoe care device 1 can be configured such that air circulation and shoe rotation both occur within the receiving space 10, resulting in excellent shoe management and display.

[0219] The movable body 200 can be configured to include a lower protective member 240. The lower protective member 240 is fixedly coupled to the outer side of the boundary of the base 220. The lower protective member 240 is fixedly coupled to the front surface 220b, left surface 220c, and right surface 220d of the base 220 (see...). Figure 7a ).

[0220] The lower protective element 240 can be configured in a substantially C-shape (or...) on the plan view. (Shapes, shapes, or ┏┓ shapes). In the plan view, the shape of the lower protective member 240 can be configured to correspond to the shape of the transparent window 210.

[0221] The lower protective component 240 can be positioned outside the lower main body 110.

[0222] The lower protective member 240 is configured to include a first lower protective member 240a, a second lower protective member 240b, and a third lower protective member 240c. The lower protective member 240 can be configured as a single unit.

[0223] The first lower protective member 240a forms the front surface of the lower protective member 240. The outer and inner surfaces of the first lower protective member 240a can be configured to be orthogonal to the first direction X. The second lower protective member 240b forms the left surface of the lower protective member 240. The outer and inner surfaces of the second lower protective member 240b can be configured to be orthogonal to the second direction Y. The third lower protective member 240c forms the right surface of the lower protective member 240. The outer and inner surfaces of the third lower protective member 240c can be configured to be orthogonal to the second direction Y.

[0224] The first lower protective member 240a can be positioned at the front side of the front end of the lower main body 110. The second lower protective member 240b can be positioned at the left side of the left end of the lower main body 110. The third lower protective member 240c can be positioned at the right side of the right end of the lower main body 110.

[0225] In the shoe care device 1 according to an embodiment of the present invention, the lower side of the transparent window 210 can be fixedly inserted between the base 220 and the lower protective member 240.

[0226] The transparent window 210 can be configured to include a hidden portion 216.

[0227] The hidden portion 216 extends downward from the first window 211, the second window 212, and the third window 213. The hidden portion 216 can be divided into a first hidden portion 216a, a second hidden portion 216b, and a third hidden portion 216c. The first hidden portion 216a extends downward from the lower end of the first window 211. The second hidden portion 216b extends downward from the lower end of the second window 212. The third hidden portion 216c extends downward from the lower end of the third window 213.

[0228] The front surface 220b, left surface 220c and right surface 220d of the base 220 are in close contact with the inner surface of the hidden portion 216.

[0229] The inner surface of the lower protective member 240 is in close contact with the outer surface of the concealed portion 216 and is fixed to the base 220.

[0230] The transparent window 210 can be configured to include a plurality of first through holes 217.

[0231] The first through hole 217 is configured as a hole that penetrates the transparent window 210 at the underside of each of the first window 211, the second window 212 and the third window 213.

[0232] The first through hole 217 can be arranged in a horizontal direction. The first through hole 217 formed on the lower side of the first window 211 is arranged in the second direction Y. The first through hole 217 formed on the lower side of the second window 212 is arranged in the first direction X, and the first through hole 217 formed on the lower side of the third window 213 is also arranged in the first direction X.

[0233] The first through hole 217 can be formed in the hidden portion 216. That is, the first through hole 217 can be configured as a hole that penetrates the hidden portion 216. The first through hole 217 can be formed in each of the first hidden portion 216a, the second hidden portion 216b, and the third hidden portion 216c.

[0234] The base 220 can be configured to include a plurality of second through holes 223. The second through holes 223 are formed on each of the front surface 220b, left surface 220c and right surface 220d of the base 220.

[0235] A second through hole 223 formed on the front surface 220b of the base 220 is arranged along the second direction Y. A second through hole 223 formed on the left surface 220c of the base 220 is arranged along the first direction X, and a second through hole 223 formed on the right surface 220d of the base 220 is also arranged along the first direction X.

[0236] The second through hole 223 can be formed at a position corresponding to the first through hole 217.

[0237] The lower guard 240 can be configured to include a plurality of hooks 242. The hooks 242 protrude inwardly on the inner surface of the lower guard 240. The hooks 242 protrude inwardly on the inner surface of each of the first lower guard 240a, the second lower guard 240b, and the third lower guard 240c.

[0238] Hook 242 is configured to be inserted into and hooked into second through hole 223 by passing through first through hole 217.

[0239] Hook 242 can be configured to include a first hook 242a and a second hook 242b. The hooking positions of the first hook 242a and the second hook 242b can be configured to be opposite to each other.

[0240] For example, when the first hook 242a is hooked to the upper side of the second through hole 223, the second hook 242b can be hooked to the lower side of the second through hole 223. Alternatively, when the first hook 242a is hooked to the lower side of the second through hole 223, the second hook 242b can be hooked to the upper side of the second through hole 223 (see...). Figure 9a and Figure 9b ).

[0241] The first hook 242a and the second hook 242b can be arranged to repeat each other in the horizontal direction.

[0242] A mounting rib 222 supporting the lower end of the transparent window 210 may be formed in the base 220. The mounting rib 222 may protrude outward at the boundary of the base 220. The mounting rib 222 may protrude outward on the front surface 220b, left surface 220c and right surface 220d of the base 220.

[0243] A claw 224 may be formed in the base 220. The claw 224 protrudes outward over the entire or part of the lower boundary of the second through hole 223. The claw 224 formed on the front surface 220b of the base 220 protrudes forward, the claw 224 formed on the left surface 220c of the base 220 protrudes to the left, and the claw 224 formed on the right surface 220d of the base 220 protrudes to the right.

[0244] While assembling the base 220 and the transparent window 210, the lower end of the transparent window 210 (the lower end of the hidden portion 216) is placed on the upper surface of the mounting rib 222, and the claw 224 of the base 220 is inserted into the first through hole 217 and hooked onto the lower side of the first through hole 217. In this case, the hook 242 (specifically the first hook 242a) is positioned above the claw 224. As a result, the base 220 and the transparent window 210 can be connected more stably (see...). Figure 9b ).

[0245] As described above, in the shoe care device 1 according to an embodiment of the present invention, the base 220 forms the bottom of the movable body 200. The front surface 220b, left surface 220c, and right surface 220d of the base 220 are in close contact with the inner surface of the hidden portion 216 of the transparent window 210, the inner surface of the lower protective member 240 is in close contact with the outer surface of the hidden portion 216, and the lower protective member 240 is fixed to the base 220.

[0246] The lower side of the transparent window 210 is fixed by the base 220 and the lower protective member 240 to form a rigid connection structure of the moving body 200. In addition, the area of ​​the transparent portion (transparent window 210) in the moving body 200 can be maximized.

[0247] As described above, the hook 242 of the lower protective member 240 is configured to be inserted into and hooked into the second through hole 223 of the base 220 through the first through hole 217 of the transparent window 210. Furthermore, the hooking positions of the first hook 242a and the second hook 242b can be configured to be opposite each other.

[0248] As a result, while the connecting portion (hidden portion 216) of the transparent window 210 is not visually exposed to the outside, the transparent window 210, the base 220, and the lower protective member 240 can be stably connected.

[0249] The outer surface of the hidden portion 216 is stepped, recessed on the outer surfaces of the first window 211, the second window 212, and the third window 213. The outer surface of the first hidden portion 216a can be configured to be recessed inward on the outer surface of the first window 211, the outer surface of the second hidden portion 216b can be configured to be recessed inward on the outer surface of the second window 212, and the outer surface of the third hidden portion 216c can also be configured to be recessed inward on the outer surface of the third window 213.

[0250] The inner surface of the first hidden portion 216a can form the same plane as the inner surface of the first window 211, the inner surface of the second hidden portion 216b can form the same plane as the inner surface of the second window 212, and the inner surface of the third hidden portion 216c can form the same plane as the inner surface of the third window 213.

[0251] While the hidden portion 216 of the transparent window 210 and the lower protective member 240 are connected, the total thickness of the hidden portion 216 and the lower protective member 240 can be configured to correspond to the thickness of each of the first window 211, the second window 212 and the third window 213.

[0252] The total thickness of the first hidden portion 216a and the first lower protective member 240a can be configured to correspond to the thickness of the first window 211.

[0253] The total thickness of the second concealed portion 216b and the second lower protective member 240b can be configured to correspond to the thickness of the second window 212. The total thickness of the third concealed portion 216c and the third lower protective member 240c can be configured to correspond to the thickness of the third window 213 (see [reference]). Figure 9a and Figure 9b ).

[0254] The height of the upper end of the concealed portion 216, the height of the upper end of the lower protective member 240, and the height of the upper end of the base 220 can be configured to correspond to each other (see [reference]). Figure 9a and Figure 9b ).

[0255] As described above, a shoe care device 1 can be provided, wherein the transparent window 210, the base 220 and the lower protective member 240 are stably connected to the lower side of the movable body 200, thereby enhancing the aesthetics of the movable body 200.

[0256] Figure 6 This is a cross-sectional view showing the lower side of a shoe care device 1 according to an embodiment of the present invention.

[0257] Multiple rotating balls 260 can be rotatably connected to the turntable housing 221. The rotating balls 260 can protrude in the direction on the second base surface 221a. The rotating balls 260 can make point contact with the bottom surface of the turntable 230 to support the load of the turntable 230.

[0258] Figure 7a It is shown Figure 6 A close-up view of the socket 228 and the rotating ball 260. Figure 7b It shows from Figure 5c A magnified view of the state of socket 228 with the rotating ball 260 removed. Figure 7c It shows from Figure 5c A partial cross-sectional view of the state where the rotating ball 260 is removed from the socket 228.

[0259] The turntable receiving portion 221 may have multiple sockets 228. Sockets 228 may have portions to which a rotating ball 260 is rotatably connected. Each socket 228 may include a receiving body 228a and a restraining protrusion 228b.

[0260] The receiving body 228a may have a downward protruding shape extending from the turntable receiving portion 221. The receiving body 228a may be formed into a hemispherical shell shape. The receiving body 228a may form an upwardly opening hemispherical groove 228c inside the hemispherical shell shape. The receiving body 228a may at least accommodate the lower portion of the rotating ball 260. The rotating ball 260 may be inserted into the hemispherical groove 228c.

[0261] All 260 rotating balls can be made into a perfectly spherical shape.

[0262] The radius of curvature of the inner surface of the hemispherical groove 228c can be slightly larger than the radius of the rotating sphere 260. That is, the diameter of the inner surface of the hemispherical groove 228c can be larger than the diameter of the rotating sphere 260. Therefore, the rotating sphere 260 can make point contact with the inner surface of the hemispherical groove 228c while being inserted into it. Thus, the rotating sphere 260 can rotate smoothly while being inserted into the hemispherical groove 228c.

[0263] The top of the rotating ball 260 can make point contact with the bottom surface of the turntable 230 to support the load of the turntable 230. The kinetic energy of the turntable 230 can be transferred to the rotating ball 260 through the point contact between the bottom of the turntable 230 and the top of the rotating ball 260. In this case, the rotating ball 260 can rotate by the kinetic energy of the turntable 230 while being inserted into the hemispherical groove 228c.

[0264] Since the rotating ball 260 makes point contact with the receiving body 228a and the turntable 230, and rolls using the kinetic energy of the turntable 230, the frictional resistance between the turntable 230 and the rotating ball 260 can be reduced, thereby reducing the kinetic energy loss of the motor 290. Therefore, a motor 290 with a smaller capacity than existing motors can be used to rotate the turntable 230. Thus, the size and weight of the shoe care device 1 can be reduced by decreasing the capacity of the motor 290.

[0265] The rotating shaft of motor 290 is simply inserted into a boss on the bottom surface of turntable 230 to transmit rotational force, and rotating ball 260 can support the load of turntable 230 and shoe S. During the rotation of turntable 230, rotating ball 260 can distribute and support the load of turntable 230 and shoe S while rotating with the kinetic energy passing through the bottom surface of turntable 230.

[0266] Therefore, even when the center of gravity of the shoe S is spaced apart from the rotation axis of the turntable 230 in the horizontal direction, elastic bending deformation of the turntable 230 can be prevented. Therefore, even when the shoe care device 1 is used for a long period of time, fatigue failure of the turntable 230 due to the load of the shoe S can be minimized, and the upper surface of the turntable 230 can remain flat for a long time.

[0267] The 260 rotating ball can be made of engineering plastics with excellent strength and elasticity.

[0268] In one example, the rotating ball 260 may be made of polyamide, polyacetal, polycarbonate, polyethylene terephthalate, modified polyphenylene ether, etc.

[0269] As described above, each of the rotating spheres 260 can form a complete spherical shape. Therefore, the height of the rotating sphere 260 can always be constant relative to the second base surface 221a. Therefore, the height of the upper surface of the rotating turntable 230 can always be constant relative to the first base surface 220a. Thus, the shoe S can rotate at a constant height, and the display effect of the shoe S can be improved.

[0270] Multiple through holes 228d can be formed in the receiving body 228a. The through holes 228d can reliably pass through the receiving body 228a. The formation of the through holes 228d can reduce the contact area between the inner surface of the receiving body 228a and the rotating ball 260.

[0271] Therefore, the friction between the receiving body 228a and the rotating ball 260 can be reduced, thereby minimizing the kinetic energy loss of the motor 290. Therefore, the turntable 230 can rotate using a motor 290 with a smaller capacity than existing motors. Therefore, the size and weight of the shoe care device 1 can be reduced by decreasing the capacity of the motor 290.

[0272] The through hole 228d can be formed in both upward and downward directions. The through hole 228d can be rotationally symmetrical with respect to an imaginary longitudinal axis at the center of the radius of curvature of the inner surface of the hemispherical groove 228c.

[0273] The formation of the through-hole 228d promotes the elastic deformation of the receiving body 228a. Therefore, when the shoe S is placed on the turntable 230, the impact force applied to the turntable 230 can be dissipated through the elastic deformation of the receiving body 228a. Thus, the possibility of damage to the turntable 230 and the rotating ball 260 due to the impact force applied to the turntable 230 when the shoe S is placed on it can be reduced.

[0274] Constraint protrusions 228b may extend upward from the edge of the hemispherical groove 228c to prevent the separation of the rotating ball 260. Each constraint protrusion 228b may have a contact surface (hereinafter referred to as "constraint surface 228e") that prevents the separation of the rotating ball 260. Constraint surface 228e may have the same curvature as the inner surface of the hemispherical groove 228c.

[0275] The hemispherical groove 228c can reliably form a hemispherical shape. Therefore, the inner surface of the hemispherical groove 228c can have its maximum diameter at the top of the hemispherical groove 228c. Furthermore, the constraint protrusion 228b can extend upwards from the edge of the hemispherical groove 228c. Therefore, the constraint surface 228e can be closer to the imaginary longitudinal axis pointing towards the top of the constraint surface, through the center of the radius of curvature of the inner surface of the hemispherical groove 228c.

[0276] Multiple constraint protrusions 228b may be provided at the edge of the hemispherical groove 228c. The constraint protrusions 228b may be rotationally symmetrical with respect to an imaginary longitudinal axis centered on the radius of curvature of the inner surface of the hemispherical groove 228c. Therefore, the constraint surfaces 228e may be closer to each other towards their tops.

[0277] The imaginary circle connecting the top of the constraint surface 228e can have a smaller diameter than the rotating sphere 260. Therefore, the constraint protrusion 228b can prevent the rotating sphere 260 from separating from the hemispherical groove 228c.

[0278] When the rotating ball 260 is inserted into the hemispherical groove 228c, the constraint protrusion 228b can be elastically bent and deformed by the rotating ball 260. That is, the constraint protrusion 228b can be dispersed from each other by the rotating ball 260 around an imaginary longitudinal axis centered on the radius of curvature of the inner surface of the hemispherical groove 228c, and then return again.

[0279] The top of the rotating ball 260 can be higher than the top of the constraint protrusion 228b. Therefore, the constraint protrusion 228b can abut against the bottom surface of the turntable 230 without friction.

[0280] Both the constraint protrusion 228b and the through hole 228d are rotationally symmetrical with respect to the center of the hemispherical groove 228c, but the through hole 228d can be located below the constraint protrusion 228b. The constraint surface 228e can be connected to the internal space of each through hole 228d. When the rotating ball 260 moves toward one of the through holes 228d in the hemispherical groove 228c, the inner surface of the constraint surface 228e or the through hole 228d can make point contact with the rotating ball 260.

[0281] Figure 8 It shows from Figure 5c A plan view of the state where the moving main body 200 removes the turntable 230.

[0282] Each constraint protrusion 228b may include a pair of first constraint protrusions 228b1 and a pair of second constraint protrusions 228b2.

[0283] A pair of first constraint protrusions 228b1 can be positioned at the same radius around the vertical axis 231 and the center of the hemispherical groove 228c. That is, one and the other of the pair of first constraint protrusions 228b1 can be positioned at the same radius around the vertical axis 231 and the center of the hemispherical groove 228c, and can be positioned opposite each other around an imaginary longitudinal axis passing through the center of the radius of curvature of the inner surface of the hemispherical groove 228c.

[0284] During the reciprocating rotation of the turntable 230, the direction of the kinetic energy applied from the turntable 230 to the rotating ball 260 forms a circumferential direction around the vertical axis 231.

[0285] Furthermore, a pair of first constraint protrusions 228b1 are positioned in the direction of energy transfer from the turntable 230 to the rotating ball 260 during the reciprocating rotation of the turntable 230. Therefore, the pair of first constraint protrusions 228b1 can firmly prevent the rotating ball 260 from separating by the kinetic energy applied from the turntable 230 to the rotating ball 260.

[0286] A pair of second constraint protrusions 228b2 may be arranged about a vertical axis 231 on a line passing through the center of the hemispherical groove 228c. That is, one and the other of the pair of second constraint protrusions 228b2 may be arranged about a vertical axis 231 on a line passing through the center of the hemispherical groove 228c, and may be arranged opposite to each other relative to an imaginary longitudinal axis at the center of the radius of curvature of the inner surface of the hemispherical groove 228c.

[0287] When the center of gravity of shoe S is horizontally separated from the vertical axis 231, the centrifugal force acting on shoe S during the reciprocating rotation of turntable 230 acts in a direction away from the vertical axis 231.

[0288] One of the pair of second constraint protrusions 228b2 is positioned along the direction of centrifugal force transmission during the reciprocating rotation of the turntable 230. Therefore, during the rotation of the turntable 230, the pair of second constraint protrusions 228b2 can prevent the separation of the rotating ball 260 by the centrifugal force acting on the shoe S.

[0289] The rotating ball 260 is rotationally symmetrical about the vertical axis 231. Therefore, the rotating ball 260 can be distributed and support the load of the turntable 230 and the shoe S in a rotationally symmetrical manner about the vertical axis 231. Therefore, the load of the turntable 230 and the shoe S can be distributed in a rotationally symmetrical manner about the vertical axis 231 and applied to the turntable housing 221.

[0290] Therefore, even when the center of gravity of the shoe S is horizontally spaced from the rotation axis of the turntable 230, elastic bending deformation of the turntable 230 can be prevented. Thus, even when the shoe care device 1 is used for a long period of time, fatigue failure of the turntable 230 due to the load of the shoe S is minimized, and the upper surface of the turntable 230 can remain flat for a long time.

[0291] The rotating ball 260 may include a plurality of first rotating balls 261 and a plurality of second rotating balls 262.

[0292] The first rotating ball 261 can be arranged circumferentially at a first distance 261L from the vertical axis 231. The second rotating ball 262 can be arranged circumferentially at a second distance 262L from the vertical axis 231. The second distance 262L can be longer than the first distance 261L.

[0293] The first rotating ball 261 and the second rotating ball 262 can have the same shape and size. That is, the first rotating ball 261 and the second rotating ball 262 can be distinguished by their distance from the vertical axis 231.

[0294] The first rotating ball 261 can be distributed in a rotationally symmetrical manner around the vertical axis 231 at a first distance 261L and support the load of the turntable 230 and the shoe S. The second rotating ball 262 can be distributed in a rotationally symmetrical manner around the vertical axis 231 at a second distance 262L and support the load of the turntable 230 and the shoe S.

[0295] Even when the center of gravity of shoe S is horizontally spaced from the rotation axis of turntable 230, the center of gravity of shoe S can be closer to the vertical axis 231 than the edge near the turntable 230. When the rotating balls 260 are horizontally closer to the center of gravity of shoe S, the rotating balls 260 support a greater weight. Therefore, the number of first rotating balls 261 can be greater than the number of second rotating balls 262.

[0296] When more of the rotating balls 260 are positioned at a first distance 261L closer to the rotation axis of the turntable 230 than the second distance 262L, the weight of the shoe S can be evenly distributed across the entire first rotating ball 261 and the second rotating ball 262. Therefore, even when the shoe care device 1 is used for a long time, fatigue failure of the turntable 230, rotating balls 260, and base due to the load on the shoe S can be minimized, and the upper surface of the turntable 230 can remain flat for a long time.

[0297] Figure 9a It is shown Figure 1a A perspective view of the shoe care device 1 in an open state, and showing the information sheet 500 connected to the second inner cabinet.

[0298] Figure 9b It is shown Figure 1a A perspective view of the shoe care device 1 in an open state, and showing the state of the information piece 500 moving through the second gap.

[0299] like Figure 9a and Figure 9b As shown, the shoe care device 1 according to an embodiment of the present invention also includes an information sheet 500. The information sheet 500 can be detachably connected to the main body within the receiving space by magnetic force.

[0300] like Figure 9a As shown, with the receiving space 10 open, the user can insert or remove the information piece 500 into or from the receiving space 10 through the second gap. Alternatively, the user can insert or remove the information piece 500 into or from the receiving space 10 through the third gap while slightly tilting the information piece 500.

[0301] The main body 100 may include an intermediate main body 120 that forms the rear surface of the receiving space 10 together with the information sheet 500.

[0302] The front surface of the intermediate body 120 may include a first centered front surface 120a. The first centered front surface 120a may be a surface in close contact with the information sheet 500.

[0303] When the information chip 500 separates from the intermediate body 120, the first centered front surface 120a can form the rear surface of the receiving space 10. In the receiving space 10, the first centered front surface 120a can form a rectangular plane.

[0304] like Figure 9b As shown, the information sheet 500 can be in close contact with the first centered front surface 120a through magnetic force. When the information sheet 500 is in close contact with the first centered front surface 120a, the front surface of the information sheet 500 can form the rear surface of the receiving space 10 together with the first centered front surface 120a.

[0305] Figure 10a It is shown Figure 9a A three-dimensional view of the front surface of the information chip 500. Figure 10b It is shown Figure 9a A three-dimensional view of the rear surface of information chip 500.

[0306] The information sheet 500 can have the shape of a thin plate. The rear surface of the information sheet 500 can be in close contact with the front surface of the intermediate body 120.

[0307] The front and / or rear surfaces of the information sheet 500 may have a shape similar to the front surface of the intermediate body 120. For example, the first centered front surface 120a may be rectangular, and the front surface of the information sheet 500 may also have a rectangular shape.

[0308] The front and / or rear surfaces of the information sheet 500 may have a shape different from that of the front surface of the intermediate body 120.

[0309] In the example, the first centered front surface 120a can have a rectangular shape, and the front and / or rear surfaces of the information sheet 500 can have a circular, elliptical, or polygonal shape. Alternatively, the front and / or rear surfaces of the information sheet 500 can have various shapes, such as people, animals, and clouds.

[0310] As described above, the information sheet 500 can be aesthetically pleasing with various colors and shapes. Therefore, the internal effect of the information sheet 500 can be maximized. By creating various aesthetic appeals with the information sheet 500, the display effect of the shoe S can be improved.

[0311] The front surface of the information sheet 500 may be made of the same or similar material as the front surface of the intermediate body 120.

[0312] Therefore, regardless of whether the information sheet 500 is attached to the front surface of the intermediate body 120, the light reflected from the rear surface of the receiving space 10 from the first illuminator 410 and the second illuminator 420 can be transmitted to the field of vision of the person viewing the shoe S in the same or similar manner. Therefore, regardless of whether the information sheet 500 is attached to the front of the intermediate body 120, the receiving space 10 can create a certain aesthetic effect based on light.

[0313] Information sheet 500 can specifically refer to a sheet containing information. Information can be a broad set of symbols, such as characters, shapes, images, etc. In one example, information sheet 500 could be a sheet printed with photographs, drawings, or text.

[0314] The information sheet 500 can be exposed to the view of a person viewing the shoes S housed in the shoe care device 1. Therefore, the user of the shoe care device 1 can display photos and drawings on the rear surface of the housing space 10 by attaching the information sheet 500 to the front surface of the intermediate body 120.

[0315] The information sheet 500 may include one or more magnets 540. Recessed portions (hereinafter referred to as "recesses") 521 may be formed on the rear surface of the information sheet 500. Multiple recesses 521 may be formed along the edges of the information sheet 500. Permanent magnets 540 may be inserted into the recesses 521. The magnets 540 may be attracted by magnetic force to a magnetic plate 127 disposed on the intermediate body 120.

[0316] Figure 11 This is a perspective view of the shoe care device 1 according to an embodiment of the present invention, viewed from the rear.

[0317] Figure 12 This shows the first outer cabinet 136 and the second outer cabinet 125. Figure 1a A three-dimensional view of the shoe care device 1 in a separated state.

[0318] The main body 100 may include an upper body 130. The upper body 130 may be positioned above the receiving space 10. The upper body 130 may have an upper space 130a in which airflow is disconnected from the receiving space. The upper space 130a may have a hexahedral shape, wherein the length in the first direction X and the second direction Y is greater than the length in the third direction Z.

[0319] The upper body 130 may include a first inner cabinet 135 and a first outer cabinet 136. The first inner cabinet 135 and the first outer cabinet 136 can together form a receiving space 10.

[0320] As shown in the figure, the first inner cabinet 135 may have an upward-opening rectangular box shape. The first inner cabinet 135 may have an airflow channel 300 connected to the accommodating space 10. The first inner cabinet 135 may include an upper base plate 135a.

[0321] The upper base plate 135a can separate the receiving space 10 and the upper space 130a. The lower surface of the upper base plate 135a can form the top of the receiving space 10. The upper surface of the upper base plate 135a can form the bottom of the upper space 130a. The upper base plate 135a can have a relatively wide plate shape in the horizontal direction.

[0322] The blowing section 330 is a component that circulates air within the receiving space 10. The blowing section 330 and the air flow channel 300 can be provided on the upper surface of the upper base plate 135a.

[0323] The blowing unit 330 may include a fan 331 and a fan housing 332. The fan 331 supplies air under pressure through the rotational motion of its impeller. The fan housing 332 may form part of the airflow passage 300.

[0324] The heater 340 can be configured to directly or indirectly heat the air in the accommodating space 10. The heater 340 can be disposed in the main body 100. The heater 340 can be disposed in the air flow channel 300.

[0325] like Figure 2b As shown, inlet 310 and outlet 320 can be formed in upper base plate 135a.

[0326] Air within the containment space 10 can be drawn into the airflow channel 300 through the inlet 310. Air in the airflow channel 300 can be discharged back into the containment space 10 through the outlet 320. Therefore, the air forcibly blown by the blowing unit 330 can circulate within the containment space 10 and the airflow channel 300.

[0327] The first illuminator 410 can emit light onto the upper surface of the turntable 230, on which the shoe S is positioned at the extension of the vertical axis 231. The second illuminator 420 can be configured to illuminate the front surface of the intermediate body 120 from behind the first illuminator 410. The first illuminator 410 and the second illuminator 420 can be connected to the upper base plate 135a.

[0328] The controller 600 can be connected to the upper base plate 135a.

[0329] The intermediate main body 120 may include a second inner cabinet 124 and a second outer cabinet 125. The first outer cabinet 136 and the second outer cabinet 125 may be connected to the second inner cabinet 124 by a plurality of bolts 126b.

[0330] The second inner cabinet 124 may include a magnetic plate 127 and a resin panel 126.

[0331] The resin panel 126 can form the rear surface of the accommodating space. The magnetic plate 127 can be attached to the rear surface of the resin panel 126.

[0332] Given that the upper body 130 is a cantilever structure protruding from the middle body 120, problems such as the front end of the upper body 130 may occur when the middle body 120 does not adequately support the upper body 130.

[0333] In the shoe care device 1 according to an embodiment of the present invention, when the magnetic plate 127 having a relatively high density is attached to the rear surface of the resin panel 126 having a relatively low density, the center of gravity of the second inner cabinet 124 is positioned behind the resin panel 126, and this can be used as a factor to prevent the front end of the upper body 130 from sagging.

[0334] The magnetic plate 127 can be made of a ferromagnetic material, which is strongly magnetized in the direction of the magnetic field when a magnetic field is applied. For example, the magnetic plate 127 can be made of iron, cobalt, nickel, or their alloys. Therefore, the magnetic plate 127 can attract the permanent magnet 540 connected to the information chip 500 by magnetic force.

[0335] The first inner cabinet 135 and the second inner cabinet 124 can be connected to the frame body 800. The frame body 800 can be an element forming the skeleton of the body 100. The body 100 can be reinforced by the frame body 800.

[0336] As a part connected to the main body 100 and supporting the main body 100 in the shape of connecting the upper, lower and rear surfaces of the main body 100, the frame body 800 can strengthen each connecting part of the main body 100 that is structurally relatively fragile in rigidity.

[0337] As described above, in order for the movable body 200 to be slidably movable relative to the body 100, the front surface of the body 100 needs to be opened to correspond to the shape of the movable body 200. Therefore, the body 100 should be formed in a structure that can substantially support the load applied to the opened front surface, even in parts other than the front surface.

[0338] However, since the main body 100 has various components placed therein, and can be formed to an infinite size or rigidity, it is necessary to reinforce the vulnerable parts of the structure with separate reinforcing members.

[0339] In particular, when the body 100 is formed in a shape with the front surface open, it is necessary to support the load applied to the front surface, even on the remaining upper, lower and rear surfaces, so it is preferable to reinforce each connecting part of the component.

[0340] Therefore, in the shoe care device 1 according to the embodiment, since the frame body 800 is connected to the body 100 in a shape that connects the upper surface, lower surface and rear surface of the body 100 to support the body 100, the shoe care device 1 can maintain a stable state by reinforcing the structurally weak parts in the body 100.

[0341] In the shoe care device 1 according to an embodiment of the present invention, the frame body 800 may include an upper frame 830 connected to the upper body 130, a lower frame 810 connected to the lower body 110, and an intermediate frame 820 connected to the intermediate body 120 and connecting the rear side of the upper frame 830 and the rear side of the lower frame 810.

[0342] Multiple bosses 126a with female threads can protrude rearward from the rear surface of the resin panel 126. Therefore, the intermediate frame 820 can be fastened to the bosses 126a by bolts 126b.

[0343] When viewed from the side, the main body 100, which includes the combined lower main body 110, middle main body 120 and upper main body 130, can be formed into a U-shape, so that the main body 100 can form the three surfaces of the shoe care device 1 in three-dimensional space.

[0344] Therefore, since the upper body 130 and the lower body 110 are formed to protrude forward from the middle body 120, there is actually no structure for supporting the load at the front end of the upper body 130 and the front end of the lower body 110.

[0345] In particular, considering that the upper body 130 is a cantilever structure that protrudes from the middle body 120, problems such as the front end of the upper body 130 may occur when the middle body 120 does not adequately support the upper body 130.

[0346] In this case, considering the structural limitations of using only the intermediate body 120 to support the upper body 130, it is preferable to strengthen the connection between the lower body 110 and the intermediate body 120 via the frame body 800, and then strengthen both the intermediate body 120 and the upper body 130 via the frame body 800.

[0347] Therefore, it is preferable to provide reinforcement in a structure in which the upper body 130, lower body 110 and middle body 120 of the main body 100 are connected to each other by the upper frame 830, lower frame 810 and middle frame 820 of the frame body 800.

[0348] In other words, when viewed from the side, the frame body 800 can also be formed into a U-shape, thereby strengthening the weaker structural part of the U-shaped body 100.

[0349] Therefore, in the shoe care device 1 according to this embodiment, the frame body 800 includes an upper frame 830, a lower frame 810 and a middle frame 820, such that the weak part of the body 100 can be strengthened by the structure in which the upper body 130, the lower body 110 and the middle body 120 are connected to each other.

[0350] In the shoe care device 1 according to an embodiment of the present invention, the upper frame 830, the lower frame 810 and the middle frame 820 can be formed by bending a member that is formed to extend in the longitudinal direction.

[0351] In the shoe care device 1 according to this embodiment, the frame body 800, which includes an upper frame 830, a lower frame 810 and a middle frame 820, can be formed by bending a member that is formed to extend in the longitudinal direction, thereby facilitating the manufacture of the frame body 800 and minimizing the cut surfaces of the frame body 800 corresponding to the reinforcing member.

[0352] In the shoe care device 1 according to an embodiment of the present invention, the frame body 800 may be disposed inside the body 100. Since the frame body 800 is configured not to be exposed to the outside, visual aesthetics can be provided by minimizing the exposure of components that are not directly related to the function of the shoe care device 1.

[0353] In the shoe care device 1 according to an embodiment of the present invention, a plurality of frame bodies 800 may be arranged along the left / right direction of the body 100.

[0354] The main frame 800 may include a first main frame 800A and a second main frame 800B. The first main frame 800A may be located on the left side of the main body 100. The second main frame 800B may be located on the right side of the main body 100.

[0355] It is preferable to place the frame body 800 on the entire surface of the body 100 to reinforce the weak parts of the body 100. However, this structure may be uneconomical and may increase the weight of the shoe care device 1.

[0356] Therefore, it can be considered that, when considering structural rigidity and product economy, arranging the first frame body 800A and the second frame body 800B at a predetermined interval to a degree that can ensure structural stability is the most effective approach.

[0357] In this case, in order to prevent structural warping and other deformations caused by the rigidity imbalance of the shoe care device 1, it is preferable to arrange the first frame body 800A and the second frame body 800B symmetrically along the left / right direction of the body 100.

[0358] Therefore, in the shoe care device 1 according to this embodiment, a plurality of frame bodies 800 are arranged along the left / right direction of the body 100 to strengthen the body 100, so that the structural reinforcement of the body 100 can be more uniform and stable.

[0359] Figure 13a It is shown Figure 12 A three-dimensional view of the front surface of the second inner cabinet. Figure 13b It is shown Figure 12 A three-dimensional view of the rear surface of the second inner cabinet. Figure 13c It shows Figure 12 The rear surface of the second inner cabinet.

[0360] The second inner cabinet 124 may include a magnetic plate 127 and a resin panel 126.

[0361] The resin panel 126 can form the rear surface of the accommodating space. The front surface of the resin panel 126 may include a first centered front surface 120a, a second centered front surface 120b, a third centered front surface 120c, a stepped surface 120e, and a curved surface 120f.

[0362] As described above, the first centered front surface 120a can be a surface that is in close contact with the information sheet 500. The first centered front surface 120a can have a rectangular shape.

[0363] The second centering front surface 120b can be positioned above the first centering front surface 120a. The second centering front surface 120b can be a surface that is in close contact with the rear surface of the first inner cabinet. The second centering front surface 120b can have multiple holes for fastening to the rear surface of the first inner cabinet by bolts 126b.

[0364] The second centering front surface 120b can be disposed behind the first centering front surface 120a in the first direction X. The stepped surface 120e can be formed between the first centering front surface 120a and the second centering front surface 120b. When the bottom surface of the upper base plate 135a is in close contact with the stepped surface 120e, the second centering front surface 120b can be fastened to the rear surface of the first inner cabinet by bolts 126b.

[0365] The third centering front surface 120c can be positioned below the first centering front surface 120a. The third centering front surface 120c can have a shape that extends downward from the first centering front surface 120a. The base 220 can cover the third centering front surface 120c in the closed state. The third centering front surface 120c can have multiple holes for fastening to the rear surface of the lower body 110 by bolts 126b.

[0366] The curved surface 120f can be shaped to bend backward a certain length from the left, right, and top edges of the resin panel 126. The strength of the resin panel 126 against external forces can be enhanced by the curved surface 120f.

[0367] The magnetic plate 127 may have a rectangular flat plate shape. The magnetic plate 127 may be made of a ferromagnetic material that is strongly magnetized in the direction of the magnetic field when a magnetic field is applied. In one example, the magnetic plate 127 may be made of iron, cobalt, nickel, or alloys thereof. Therefore, the magnetic plate 127 can be attracted by magnetic force to the permanent magnet 540 connected to the information sheet 500.

[0368] The magnetic plate 127 can be attached to the rear surface of the resin panel 126. As described above, the first centered front surface 120a can refer to the surface that is in close contact with the information sheet 500. The magnetic plate 127 can be positioned on the rear surface of the first centered front surface 120a such that the information sheet 500 is in close contact with the first centered front surface 120a by magnetic force.

[0369] The first centered front surface 120a can have an area larger than that of the information sheet 500. The lateral width of the first centered front surface 120a can be greater than the lateral width of the information sheet 500. Furthermore, the longitudinal width of the first centered front surface 120a can be greater than the longitudinal width of the information sheet 500. Therefore, the position of the information sheet 500 connected to the first centered front surface 120a can be adjusted.

[0370] The internal effect caused by the information sheet 500 can be maximized by adjusting the position of the first centered front surface 120a attached to the back of the shoe and housed in the storage space. The display effect of the shoe S can be enhanced by the printed content of the information sheet 500 and the aesthetics of the color / shape of the information sheet 500.

[0371] The second inner cabinet can be manufactured by integrating the magnetic plate 127 and the resin panel 126 using an insertion injection method.

[0372] Insertion injection is a method in which a high-strength metal insert (such as steel) is inserted into an injection mold, and then a polymer resin is injected to produce a molded product in which the insert and plastic are integrated.

[0373] The insertion injection method is performed in the following sequence: First, the insert is inserted into the injection mold. Then, molten resin from the injection molding machine barrel is filled into the mold to cover the insert. After the molten resin cools and solidifies within a predetermined time, the molded product, in which the insert and plastic are integrated, is ejected from the mold.

[0374] In this invention, the insert can refer to the magnetic plate 127, and the plastic can refer to the resin panel 126. Strength and rigidity are achieved through interfacial bonding between the inserted injection-integrated metal material and the injected polymer resin.

[0375] When the magnetic plate 127 and the resin panel 126 are integrally molded by injection molding, an insertion rib 126c can be formed on the rear surface of the resin panel 126. The insertion rib 126c can be formed along the edge of the magnetic plate 127.

[0376] The insertion rib 126c may include a first insertion rib 126c1 and a second insertion rib 126c2.

[0377] The first insertion rib 126c1 can be shaped to protrude rearward from the rear surface of the resin panel 126. The first insertion rib 126c1 can surround the edge of the magnetic plate 127. The first insertion rib 126c1 and the magnetic plate 127 can form strength and rigidity through interfacial bonding forces. The first insertion rib 126c1 can form the upward / downward and left / right movement boundaries of the magnetic plate 127.

[0378] The second insertion rib 126c2 may extend from behind the first insertion rib 126c1. The second insertion rib 126c2 may be formed to cover the edge of the magnetic plate 127. The second insertion rib 126c2 and the magnetic plate 127 may form strength and rigidity through interfacial bonding force. The second insertion rib 126c2 may form the forward / backward movement boundary of the magnetic plate 127.

[0379] As described above, a plurality of bosses 126a with female threads can protrude rearward from the rear surface of the resin panel 126. The intermediate frame 820 can be fastened to the bosses 126a by bolts 126b.

[0380] Multiple through holes 127h can be formed in the magnetic plate 127. A boss 126a can pass through the through holes 127h and protrude rearward toward the frame body.

[0381] When the magnetic plate 127 and the resin panel 126 are integrally molded by injection molding, the boss 126a can be in close contact with one side surface of the through hole 127h. The boss 126a forms strength and rigidity through the interfacial bonding force with one side surface of the through hole 127h.

[0382] When the magnet 540 of the information sheet 500 is located in front of the through hole 127h, the magnetic force between the information sheet 500 and the magnetic plate 127 becomes weaker. In this case, the attachment of the information sheet 500 to the first central front surface 120a can be released by various types of external forces (such as impacts applied to the shoe care device 1).

[0383] The through-hole 127h can be provided at the left and right edges of the magnetic plate 127. Therefore, the lateral width of the region 120g (hereinafter referred to as the "uniform region") where the information sheet 500 and the magnetic plate 127 form a uniform magnetic force can extend from the center of the magnetic plate 127 in a left / right direction. Thus, even when various types of external forces (such as impacts) are applied to the shoe care device 1, the information sheet 500 can remain firmly attached to the first centered front surface 120a.

[0384] The through hole 127h may include a first through hole 127h1 and a second through hole 127h2. The boss 126a may include a first boss 126a1 and a second boss 126a2.

[0385] The first through hole 127h1 can be provided at the left edge of the magnetic plate 127. Multiple first through holes 127h1 can be formed. In one example, the first through holes 127h1 can be formed at the upper and lower sides of the left edge of the magnetic plate 127.

[0386] Multiple first protrusions 126a1 can be formed. Each first protrusion 126a1 can protrude rearward through the first through hole 127h1.

[0387] The second through hole 127h2 can be provided at the right edge of the magnetic plate 127. Multiple second through holes 127h2 can be formed. In one example, the second through holes 127h2 can be formed on the upper and lower sides of the right edge of the magnetic plate 127.

[0388] Multiple second protrusions 126a2 can be formed. Each second protrusion 126a2 can protrude rearward through the second through hole 127h2.

[0389] When the magnetic plate 127 and the resin panel 126 are integrally molded by injection molding, the first boss 126a1 can be in close contact with one side surface of the first through hole 127h1.

[0390] Here, one side surface of the first through hole 127h1 can refer to the surface opposite the second boss 126a2 relative to the first boss 126a1. Furthermore, referring to one first boss 126a1, one side surface of the first through hole 127h1 can refer to the surface opposite the other first boss 126a1. The first boss 126a1 achieves strength and rigidity through the interfacial bonding force with one side surface of the first through hole 127h1.

[0391] Furthermore, when the magnetic plate 127 and the resin panel 126 are integrally molded by injection molding, the second boss 126a2 can be in close contact with one side surface of the second through hole 127h2.

[0392] Here, one side surface of the second through hole 127h2 can refer to the surface opposite to the first boss 126a1 relative to the second boss 126a2. Furthermore, referring to one second boss 126a2, one side surface of the through hole 127h can refer to the surface opposite to another second boss 126a2. The second boss 126a2 achieves strength and rigidity through the interfacial bonding force with one side surface of the second through hole 127h2.

[0393] Therefore, the movement of the magnetic plate 127 can be blocked by the constraint of the first boss 126a1 and the second boss 126a2. In addition, the movement of the magnetic plate 127 can be blocked by the interfacial bonding force with one side surface of the first boss 126a1 and the second boss 126a2.

[0394] The frame body 800 may include a first frame body 800A and a second frame body 800B.

[0395] The first frame body 800A can be located on the left side of the body 100. The first frame body 800A can be fastened to the first boss 126a1 by bolts 126b. The intermediate frame 820 of the first frame body 800A can have multiple holes through which the threaded portion of the bolts 126b passes.

[0396] The second frame body 800B can be located on the right side of the body 100. The second frame body 800B can be fastened to the second boss 126a2 by bolts 126b. The intermediate frame 820 of the second frame body 800B can have multiple holes through which the threaded portion of the bolts 126b passes.

[0397] The through hole 127h can extend through the tilting core used to form the boss 126a. That is, the through hole 127h can extend to form the path along which the tilting core used to form the boss 126a falls when the injection mold is opened. The tilting core is a well-known technique in the field of injection mold manufacturing, so its detailed description will be omitted.

[0398] The through-hole 127h can be extended through the inclined core used to form the boss 126a, and can be extended relatively long above or below the boss 126a. Therefore, even when the through-hole 127h is extended, the lateral width of the uniform region 120g can be maintained.

[0399] Therefore, even when the through hole 127h extends through the inclined core used to form the boss 126a, the lateral width of the uniform region 120g can expand from the center of the magnetic plate 127 in the left / right direction. Therefore, even when various types of external forces (such as impacts) are applied to the shoe care device 1, the information sheet 500 can remain firmly attached to the first centered front surface 120a.

[0400] While specific embodiments of the present invention have been described and illustrated above, it will be apparent to those skilled in the art that the present invention is not limited to the described embodiments, and various modifications and variations can be made without departing from the technical concept and scope of the present invention. Therefore, these modifications or variations should not be understood separately from the technical idea or viewpoint of the present invention, and the modified embodiments should be considered to fall within the scope of the claims of the present invention.
