Description

shoe manager

The present invention relates to a shoe manager, and more specifically, to a shoe manager in which shoes stored therein are managed and displayed.

Only by storing your shoes properly can you wear them for a long time without damaging their shape. If you stack your shoes in layers, their shape may change. Generally, shoe cabinets are used to organize and store shoes.

Recently, people have been collecting shoes from popular brands as a hobby or as a means of investment, and shoe cases have been introduced to store and display shoes.

Korean Patent Publication No. 2017-0130045 (hereinafter referred to as 'prior document') discloses "Three dimensions picture lighting device of turn table type", and a turntable-type 3D image lighting device accordingly. It includes a base, a transparent window, a first light emitting element, a turntable, a cover plate, a second light emitting element, and a control panel.

The base is provided at the bottom of the turntable-type 3D image lighting device. The base forms a box shape. A driving motor is provided inside the base. And a turntable is placed on the base. The turntable is rotated by a drive motor. The control panel controls the drive motor. When the drive motor is driven by operating the control panel, the product (hereinafter referred to as 'exhibit') mounted on the top of the turntable rotates together with the turntable.

The rotational force of the drive motor is transmitted to the rotation axis of the turntable through a reducer, etc. A plurality of bearings are coupled to the base. Bearings fix the rotating axis of the rotating turntable in a certain position. The rotation axis of the turntable is rotatably supported by a plurality of bearings.

However, according to the prior literature, since the radial reverberant flow of the turntable rotation axis is suppressed by a plurality of bearings, there is a high possibility that the state in which the turntable stably supports the exhibition product will be affected by the position of the center of gravity of the exhibition product.

For example, according to the prior literature, the horizontality of the turntable is maintained by bearings that support the turntable rotation axis in the rotation axis direction and/or the radial direction, so the center of gravity of the exhibit placed on the upper surface of the turntable is horizontal from the rotation axis of the turntable. If spaced apart, unevenness/deviation occurs in the force applied to the balls and/or rollers of the bearing in the direction of the rotation axis and radial direction of the turntable.

This is a major factor that not only increases the mechanical wear rate of the bearing, but also acts as a factor that causes wear and fatigue destruction of the part where the bearing is joined, making it difficult for the turntable to continuously maintain a stable support for the exhibit. That is, there is a high risk that the horizontality of the top surface of the turntable will be destroyed due to the above-mentioned wear and fatigue failure.

In addition, if unevenness/deviation occurs in the force applied to the balls and/or rollers of the bearing in the direction and radial direction of the rotation axis of the turntable, frictional force is concentrated on some of the balls and/or rollers of the bearing, preventing the smooth operation of the turntable. There is a risk that rotation may be impaired and the rotation speed of the turntable may fluctuate irregularly.

In addition, according to the preceding literature, the turntable is supported only by the rotation axis, so when the center of gravity of the exhibition product placed on the upper surface of the turntable is spaced horizontally from the rotation axis of the turntable, micro elastic bending deformation occurs in the turntable due to the load of the exhibition product. do. Since the turntable is configured to display various exhibition items for a long period of time, there is a risk that the above-mentioned microelastic bending deformation may develop into permanent plastic deformation due to the fatigue failure principle.

According to the prior literature, the turntable is illuminated by a plurality of light emitting elements. In particular, if the turntable is made of a plastic material that is vulnerable to light and heat energy, the light and heat energy of the light emitting device may act as a factor in accelerating plastic deformation due to fatigue failure.

The use of plastic materials should be pursued as it is advantageous for reducing the weight of the device and reducing the capacity of the motor. However, compared to metal materials, it is disadvantageous in terms of deformation due to light, heat, and load, so parts that are continuously subjected to light, heat, and load should be made of plastic material. To manufacture it, a structural design of the device that can prevent deformation is required.

In addition, according to the prior literature, since the rotation axis of the turntable is maintained in an upright state by a plurality of bearings, it is difficult to make the upper surface of the turntable completely horizontal.

For example, according to the prior literature, the turntable is maintained horizontally by bearings that support the turntable rotation axis in the direction of the rotation axis and/or in the radial direction, so when manufacturing a turntable-type 3D image lighting device, the bearings are slightly adjusted based on the direction of gravity. If it is installed spaced apart or tilted, there is a possibility that the top surface of the turntable may be tilted from the time of manufacture.

Accordingly, in the development of a shoe care device with a turntable, it must be considered whether the turntable can rotate smoothly while maintaining a stable state regardless of the point where the load of the shoe is applied on the upper side of the turntable. The development of a shoe care device that takes into account this is required.

One problem that the present invention seeks to solve is to provide a shoe care device in which the turntable can continuously maintain a stable support for the shoe regardless of the position of the shoe's center of gravity.

One problem that the present invention seeks to solve is to provide a shoe care device that can minimize wear and tear on mechanical elements that bear the load of shoes even if shoes are displayed on the upper surface of a turntable for a long period of time.

One problem that the present invention seeks to solve is to provide a shoe care device that can maintain the turntable's rotational speed constant while maintaining the turntable's smooth rotation state for a long period of time even if the center of gravity of the shoe is separated from the center of the turntable.

One problem that the present invention seeks to solve is to provide a shoe care device that can prevent plastic deformation of the turntable due to fatigue failure even if the center of gravity of the shoe is separated from the center of the turntable.

One problem that the present invention seeks to solve is to provide a shoe care device that can block deformation caused by light and heat energy from lighting and the load of shoes even if the turntable is made of plastic material.

One problem that the present invention seeks to solve is to provide a shoe care machine that can form a completely horizontal upper surface of the turntable even when the shoes are displayed for a long period of time as well as during manufacturing.

The attachment may include a receiving body and a restraining protrusion.

The receiving body may form a hemispherical groove that accommodates at least a lower portion of the rotating ball.

The restraining protrusions may be provided in plural numbers. The restraining protrusions may extend upward from the edge of the hemispherical groove to restrain the rotation ball from leaving.

The diameter of the hemispherical groove may be larger than the diameter of the rotating ball.

The top of the rotating ball may be higher than the top of the restraining protrusion.

The moving object may include a motor.

The motor may be disposed in the lower body groove and coupled to apply rotational force to the turntable.

In the shoe care machine according to an embodiment of the present invention, as the rotating ball makes point contact with the receiving body and the turntable and rolls due to the kinetic energy of the turntable, the frictional resistance between the turntable and the rotating ball is reduced, thereby reducing the kinetic energy loss of the motor. You can do it. Therefore, the turntable can be rotated using a motor with a smaller capacity than before. Therefore, the volume and weight of the shoe care device may be reduced by reducing the motor capacity.

In the shoe care device according to an embodiment of the present invention, the rotation axis of the motor is simply inserted into the boss on the bottom of the turntable to transmit rotational force, and the rotation balls can support the load of the turntable and shoes. When the turntable rotates, the rotating balls rotate due to the kinetic energy of the bottom of the turntable and can distribute and support the load of the turntable and shoes. Therefore, even if the center of gravity of the shoe is horizontally spaced based on the turntable rotation axis, elastic bending deformation of the turntable can be prevented. And even if the shoe care machine is used for a long period of time, the wear and fatigue damage of the turntable due to the load of the shoes is minimized, and the upper surface of the turntable can maintain a flat surface for a long period of time.

In the shoe care machine according to an embodiment of the present invention, the rotating balls can form a perfect sphere shape. Therefore, the height of the rotating balls may always be constant based on the second base surface. Additionally, the height of the upper surface of the rotating turntable may always be constant relative to the first base surface. Therefore, the shoe can rotate at a certain height and the display effect of the shoe can be improved.

In the shoe care device according to an embodiment of the present invention, a plurality of through holes may be formed in the receiving body. By forming a through hole, the area of the inner surface of the receiving body that can make point contact with the rotating ball may be reduced. Therefore, the friction between the receiving body and the rotating ball is reduced, thereby minimizing the kinetic energy loss of the motor. Therefore, the turntable can be rotated using a motor with a smaller capacity than before. Additionally, the volume and weight of the shoe care device may be reduced by reducing the capacity of the motor.

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

In the shoe care device according to an embodiment of the present invention, the pair of first restraining protrusions may be located in a transfer direction of kinetic energy applied from the turntable to the rotating ball when the turntable reciprocates. Therefore, the pair of first restraining protrusions can firmly restrain the rotation ball from leaving due to the kinetic energy applied to the rotation ball from the turntable.

In the shoe care device according to an embodiment of the present invention, one of the pair of second restraining protrusions may be located in a direction in which centrifugal force is transmitted when the turntable reciprocates. Therefore, the pair of second restraining protrusions can restrain the rotation ball from leaving due to centrifugal force acting on the shoe when the turntable rotates.

In the shoe care device according to an embodiment of the present invention, the rotating balls may be rotationally symmetrical about a vertical axis. Therefore, the rotating balls can distribute and support the load of the turntable and shoes in a rotationally symmetrical form about the vertical axis. Therefore, the load of the turntable and the shoes can be distributed in a rotationally symmetrical manner about the vertical axis and applied to the table receiving portion. Therefore, even if the center of gravity of the shoe is horizontally spaced based on the turntable rotation axis, elastic bending deformation of the turntable can be prevented. Therefore, even if the shoe care device is used for a long period of time, the wear and fatigue damage of the turntable due to the load of the shoes is minimized, and the upper surface of the turntable can maintain a flat surface for a long period of time.

In the shoe care device according to an embodiment of the present invention, as more rotating balls are located at the first distance closer than the second distance based on the rotation axis of the turntable, the weight of the shoe is adjusted to the first rotating balls and the second rotating balls. can be evenly distributed throughout. Therefore, even if the shoe care machine is used for a long period of time, wear and fatigue damage to the turntable, rotating ball, and base due to the load of the shoes is minimized, and the upper surface of the turntable can maintain a flat surface for a long period of time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. However, in describing the present invention, descriptions of already known functions or configurations will be omitted to make the gist of the present invention clear.

If shoes are directly exposed to dust, water, heat and/or sunlight, the fibers of the shoes may become damaged over time and the color and shape of the shoes may change.

In order to keep shoes in their original state (e.g., the state of shoes at the time of purchase or the state of clean shoes) for a long time, shoes should not be exposed to much light and should be stored in a place that is not too cold or hot. Additionally, shoes need to be stored in a place where temperature and humidity are maintained appropriately.

Shoes made of leather or suede are prone to discoloration and mold, so they should be stored in an environment where temperature and humidity are maintained appropriately. Mothballs made of solidified pesticides and air fresheners have a unique chemical smell, so if they are stored with shoes, the smell will seep in and be very difficult to remove.

Additionally, if shoes are stacked in layers, the shape of the shoes may be deformed due to the applied load.

The locking protrusion 224 formed on the front surface 220b of the base 220 protrudes forward, and the locking protrusion 224 formed on the left side 220c of the base 220 protrudes to the left, and the base 220 ) The locking protrusion 224 formed on the right side 220d protrudes to the right.

In a state in which the base 220 and the transparent window 210 are assembled, the lower end of the transparent window 210 (the lower end of the hiding part 216) is seated on the upper surface of the seating rib 222, and the locking protrusion of the base 220 (224) is inserted into the first through hole (217) and hangs on the lower side of the first through hole (217). At this time, the hook 242 (particularly, the first hook 242a) is located above the locking protrusion 224. Accordingly, a more stable connection between the base 220 and the transparent window 210 can be achieved.

As described above, in the shoe care device 1 according to an embodiment of the present invention, the base 220 forms the bottom portion of the moving body 200. The front side (220b), left side (220c), and right side (220d) of the base 220 are in close contact with the inner side of the concealed portion 216 of the transparent window 210, and the inner side of the lower guard 240 is in close contact with the concealed portion. It is in close contact with the outer surface of 216, and the lower guard 240 is fixed to the base 220.

The lower side of the transparent window 210 is fixed by the base 220 and the lower guard 240, thereby forming a solid coupling structure of the mobile body 200. In addition, the area of the transparent part (transparent window 210) of the mobile body 200 can be secured as much as possible.

As described above, the hook 242 of the lower guard 240 passes through the first through hole 217 of the transparent window 210 and is inserted into and caught in the second through hole 223 of the base 220. . Additionally, the hooked position of the first hook 242a and the hooked position of the second hook 242b may be opposite to each other.

Accordingly, the transparent window 210, the base 220, and the lower guard 240 can be stably coupled without the coupling portion (concealing portion 216) of the transparent window 210 being visually exposed from the outside. there is.

The outer surface of the concealed portion 216 is dented and stepped from the outer surfaces of the first window 211, the second window 212, and the third window 213. The outer surface of the first concealed portion 216a is recessed inward from the outer surface of the first window 211, and the outer surface of the second concealed portion 216b is recessed inward from the outer surface of the second window 212. And, the outer surface of the third concealed portion 216c may be recessed inward from the outer surface of the third window 213.

The inner surface of the first concealed part 216a may form the same plane as the inner surface of the first window 211, and the inner surface of the second concealed part 216b may be flush with the inner surface of the second window 212. It can form a plane, and the inner surface of the third concealed portion 216c can form the same plane as the inner surface of the third window 213.

In a state in which the concealing portion 216 and the lower guard 240 of the transparent window 210 are combined, the total thickness of the concealing portion 216 and the lower guard 240 is equal to that of the first window 211 and the second window ( 212) and the third window 213 may be formed to correspond to their respective thicknesses. The total thickness of the first concealment portion 216a and the first lower guard 240a may correspond to the thickness of the first window 211. The total thickness of the second concealment portion 216b and the second lower guard 240b may correspond to the thickness of the second window 212. The overall thickness of the third concealment portion 216c and the third lower guard 240c may correspond to the thickness of the third window 213.

The height of the top of the concealed portion 216, the height of the top of the lower guard 240, and the height of the top of the base 220 may correspond to each other.

By being made as described above, a shoe that can improve the aesthetics of the mobile body 200 while achieving a stable connection between the transparent window 210, the base 220, and the lower guard 240 on the lower side of the mobile body 200 A manager (1) may be provided.

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

A plurality of rotating balls 260 may be rotatably coupled to the table receiving portion 221. The rotating balls 260 may protrude upward from the second base surface 221a. The rotating balls 260 make point contact with the bottom of the turntable 230 and can support the load of the turntable 230.

FIG. 7A is a partially enlarged view showing the mounting 228 and the rotating ball 260 of FIG. 6. Figure 7b is a partial enlarged view showing the state in which the rotating ball 260 has been removed from the attachment 228 of Figure 5c. FIG. 7C is a partial cross-sectional view showing the rotating ball 260 removed from the attachment 228 of FIG. 5C.

The table receiving portion 221 may form a plurality of attachments 228. The attachments 228 may form a portion to which the rotating balls 260 are rotatably coupled. The attachment 228 may include a receiving body 228a and a restraining protrusion 228b.

The receiving body 228a may form a convex shape downward from the table receiving portion 221. The receiving body 228a may have a hemispherical shell shape. The receiving body 228a may form an upwardly open hemispherical groove 228c on the inside of the hemispherical shell shape. The receiving body 228a can accommodate at least the lower part of the rotating ball 260. The rotating ball 260 may be inserted into the hemispherical groove 228c.

The rotating balls 260 can be manufactured into a perfect sphere shape.

The radius of curvature of the inner surface of the hemispherical groove 228c may be somewhat larger than the radius of the rotating ball 260. That is, the inner diameter of the hemispherical groove 228c may be larger than the diameter of the rotating ball 260. Therefore, the rotating ball 260 can make point contact with the inner surface of the hemispherical groove 228c while being inserted into the hemispherical groove 228c. Therefore, the rotating ball 260 may be able to rotate smoothly while inserted into the hemispherical groove 228c.

The upper ends of the rotating balls 260 make point contact with the bottom of the turntable 230 and can support the load of the turntable 230. The kinetic energy of the turntable 230 may be transferred to the rotating balls 260 through point contact between the bottom of the turntable 230 and the top of the rotating balls 260. At this time, the rotating ball 260 may rotate by the kinetic energy of the turntable 230 while inserted into the hemispherical groove 228c.

As the rotating ball 260 makes point contact with the receiving body 228a and the turntable 230 and rolls due to the kinetic energy of the turntable 230, the frictional resistance between the turntable 230 and the rotating ball 260 decreases. The kinetic energy loss of the motor 290 can be reduced. Therefore, the turntable 230 can be rotated using a motor 290 with a smaller capacity than before. Therefore, the volume and weight of the shoe care device 1 may be reduced by reducing the capacity of the motor 290.

The rotation axis of the motor 290 is simply inserted into the boss of the bottom of the turntable 230 to transmit rotational force, and the rotation balls 260 can support the load of the turntable 230 and the shoe (S). When the turntable 230 rotates, the rotating balls 260 rotate by the kinetic energy of the bottom of the turntable 230 and can distribute and support the load of the turntable 230 and the shoes (S).

Therefore, even if the center of gravity of the shoe (S) is spaced apart in the horizontal direction with respect to the rotation axis of the turntable (230), elastic bending deformation of the turntable (230) can be prevented. Therefore, even if the shoe care device 1 is used for a long period of time, fatigue destruction of the turntable 230 due to the load of the shoes S is minimized, and the upper surface of the turntable 230 can maintain a flat surface for a long period of time.

The rotating balls 260 may be made of engineering plastics with excellent strength and elasticity.

As an example, the rotating balls 260 may be made of polyamide, polyacetal, polycarbonate, polyethylene terephthalate, modified polyphenylene oxide, etc. there is.

As described above, the rotating balls 260 may form a complete sphere. Therefore, the height of the rotating balls 260 may always be constant based on the second base surface 221a. Therefore, the height of the upper surface of the rotating turntable 230 may always be constant based on the first base surface 220a. Therefore, the shoe (S) can rotate at a certain height and the display effect of the shoe (S) can be improved.

A plurality of through holes 228d may be formed in the receiving body 228a. The through holes 228d can literally penetrate the receiving body 228a. By forming the through hole 228d, the area of the inner surface of the receiving body 228a that can make point contact with the rotating ball 260 may be reduced.

Accordingly, the friction between the receiving body 228a and the rotating ball 260 is reduced, thereby minimizing the kinetic energy loss of the motor 290. Therefore, the turntable 230 can be rotated using a motor 290 with a smaller capacity than before. Therefore, the volume and weight of the shoe care device 1 may be reduced by reducing the capacity of the motor 290.

Through holes 228d may be formed in the vertical direction. The through holes 228d may be rotationally symmetrical about a virtual vertical axis passing through the center of the radius of curvature of the inner surface of the hemispherical groove 228c.

Elastic deformation of the receiving body 228a may be facilitated by forming the through hole 228d. Therefore, when the shoe (S) is placed on the turntable (230), the impact force applied to the turntable (230) can be dissipated by elastic deformation of the receiving body (228a). Therefore, the possibility of damage to the turntable 230 and the rotating ball 260 due to impact force applied to the turntable 230 when the shoe S is placed on the turntable 230 can be reduced.

The restraining protrusion 228b may extend upward from the edge of the hemispherical groove 228c to restrain the rotation ball 260 from leaving. The restraining protrusions 228b may form a contact surface 228d (hereinafter referred to as 'constraint surface 228e') that restrains the rotation ball 260 from leaving. The constraining surface 228e may have the same curvature as the inner surface of the hemispherical groove 228c.

The hemispherical groove 228c can literally form a hemisphere shape. Therefore, the inner surface of the hemispherical groove 228c may form a maximum diameter at the top of the hemispherical groove 228c. And the restraining protrusion 228b may extend upward from the edge of the hemispherical groove 228c. Accordingly, the constraining surface 228e may become closer to the virtual vertical axis passing through the center of the radius of curvature of the inner surface of the hemispherical groove 228c as it moves upward.

A plurality of restraining protrusions 228b may be provided at the edges of the hemispherical groove 228c. The restraining protrusions 228b may be rotationally symmetrical about a virtual vertical axis passing through the center of the radius of curvature of the inner surface of the hemispherical groove 228c. Therefore, the constraint surfaces 228e may become closer to each other as they go upward.

The virtual circle connecting the upper ends of the constraint surfaces 228e may have a smaller diameter than the rotating ball 260. Therefore, the restraining protrusions 228b can restrain the rotation ball 260 from leaving the hemispherical groove 228c.

In the process of inserting the rotating ball 260 into the hemispherical groove 228c, the constraining protrusions 228b may be elastically bent and deformed by the rotating ball 260. That is, the restraining protrusions 228b can be spread apart from each other by the rotating ball 260 and then returned to each other around a virtual vertical axis passing through the center of the radius of curvature of the inner surface of the hemispherical groove 228c.

The top of the rotating ball 260 may be higher than the top of the restraining protrusion 228b. Therefore, the restraining protrusions 228b may not rub against the bottom surface of the turntable 230.

The restraining protrusions 228b and the through holes 228d are each rotationally symmetrical about the center of the hemispherical groove 228c, and the through hole 228d may be located below the restraining protrusions 228b. The inner surface of the constraint surface 228e and the through hole 228d may be connected. When the rotating ball 260 moves toward one of the through holes 228d within the hemispherical groove 228c, the constraint surface 228e or the inner surface of the through hole 228d may be in point contact with the rotating ball 260. there is.

FIG. 8 is a plan view showing a state in which the turntable 230 has been removed from the mobile body 200 of FIG. 5C.

The restraining protrusions 228b may include a pair of first restraining protrusions 228b1 and a pair of second restraining protrusions 228b2.

The pair of first constraining protrusions 228b1 may be disposed at the same radius as the center of the hemispherical groove 228c around the vertical axis 231. That is, one of the pair of first restraining protrusions 228b1 and the other are disposed at the same radius as the center of the hemispherical groove 228c around the vertical axis 231, and the curvature of the inner surface of the hemispherical groove 228c They can be placed on opposite sides of each other around an imaginary vertical axis passing through the center of the radius.

When the turntable 230 reciprocates, the direction of kinetic energy applied from the turntable 230 to the rotating ball 260 forms a circumferential direction around the vertical axis 231.

And the pair of first restraining protrusions 228b1 are located in the transfer direction of the kinetic energy applied from the turntable 230 to the rotating ball 260 when the turntable 230 reciprocates. Accordingly, the pair of first restraining protrusions 228b1 can firmly restrain the rotation ball 260 from leaving due to the kinetic energy applied to the rotation ball 260 from the turn table 230.

The pair of second restraining protrusions 228b2 may be arranged on a line passing through the center of the hemispherical groove 228c with the vertical axis 231 as the center. That is, one of the pair of second constraining protrusions 228b2 and the other are disposed on a line passing through the center of the hemispherical groove 228c with the vertical axis 231 as the center, and the curvature of the inner surface of the hemispherical groove 228c They can be placed on opposite sides of each other around an imaginary vertical axis passing through the center of the radius.

When the center of gravity of the shoe (S) is horizontally spaced from the vertical axis (231), the direction of the centrifugal force acting on the shoe (S) during the reciprocating rotation of the turntable (230) tends to move away from the vertical axis (231). acts in the direction

One of the pair of second restraining protrusions 228b2 is located in the direction in which centrifugal force is transmitted when the turntable 230 reciprocates. Accordingly, the pair of second restraining protrusions 228b2 may restrain the rotation ball 260 from being separated due to centrifugal force acting on the shoe S when the turntable 230 rotates.

The rotating balls 260 may achieve rotational symmetry about the vertical axis 231. Therefore, the rotating balls 260 can distribute and support the load of the turntable 230 and the shoe (S) in a rotationally symmetrical form about the vertical axis 231. Accordingly, the load of the turntable 230 and the shoe S may be distributed in a rotationally symmetrical manner about the vertical axis 231 and applied to the table receiving portion 221.

The rotating balls 260 may include a plurality of first rotating balls 261 and a plurality of second rotating balls 262.

The first rotating balls 261 may be arranged along the circumferential direction at a first distance 261L from the vertical axis 231. The second rotating balls 262 may be arranged along the circumferential direction at a second distance 262L from the vertical axis 231. The second distance (262L) may be longer than the first distance (261L).

The first rotating balls 261 and the second rotating balls 262 may have the same shape and size. That is, the first rotating balls 261 and the second rotating balls 262 can be distinguished by a distance from the vertical axis 231.

The first rotation balls 261 may distribute and support the load of the turntable 230 and the shoe S in a rotationally symmetrical form at a first distance 261L about the vertical axis 231. The second rotation balls 262 may distribute and support the load of the turntable 230 and the shoe S in a rotationally symmetrical form at a second distance 262L about the vertical axis 231.

Even though the center of gravity of the shoe (S) is horizontally spaced based on the rotation axis of the turntable (230), the center of gravity of the shoe (S) may be closer to the vertical axis (231) than the edge of the turntable (230). The rotating balls 260 support more weight the closer they are to the horizontal direction from the center of gravity of the shoe (S). Accordingly, the number of first rotating balls 261 may be greater than the number of second rotating balls 262.

As more rotating balls 260 are located at the first distance 261L, which is closer than the second distance 262L, based on the rotation axis of the turntable 230, the weight of the shoe S is increased by the first rotating balls 261 ) and can be evenly distributed throughout the second rotating balls 262. Therefore, even if the shoe care device (1) is used for a long period of time, fatigue destruction of the turntable (230), rotating ball (260), and base due to the load of the shoe (S) is minimized, so that the upper surface of the turntable (230) maintains a flat surface for a long period of time. You can.

FIG. 9B is a perspective view showing the accommodating space of the shoe care device 1 of FIG. 1A in an open state, and is a view showing the information sheet 500 moving through the second gap.

As shown in FIGS. 9A and 9B, the shoe care device 1 according to an embodiment of the present invention further includes an information sheet 500. The information sheet 500 can be detachably coupled to the main body using magnetic force within the receiving space.

As shown in FIG. 9A, when the receiving space 10 is open, the user can insert the information sheet 500 into or withdraw the information sheet 500 from the receiving space 10 through the second gap. Alternatively, the user may place the information sheet 500 in a slightly tilted state into the receiving space 10 or withdraw it from the receiving space 10 through the third gap.

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

The front of the intermediate body 120 may include a first intermediate front (120a). The first middle front 120a may refer to a surface on which the information sheet 500 is in close contact.

In a state where the information sheet 500 is separated from the intermediate body 120, the first intermediate front 120a may form the rear of the receiving space 10. In the accommodation space 10, the first middle front surface 120a may form a square-shaped plane.

As shown in Figure 9b, the information sheet 500 may be in close contact with the first middle front surface 120a by magnetic force. As the information sheet 500 is in close contact with the first middle front 120a, the front of the information sheet 500 may form the back of the receiving space 10 together with the first middle front 120a.

FIG. 10A is a perspective view showing the front of the information sheet 500 of FIG. 9A. FIG. 10B is a perspective view showing the back of the information sheet 500 of FIG. 9A.

The information sheet 500 may have a thin plate shape. The rear of the information sheet 500 may be in close contact with the front of the intermediate body 120.

The front and/or rear of the information sheet 500 may have a shape similar to the front of the intermediate body 120. For example, the first middle front 120a may have a rectangular shape, and the front of the information sheet 500 may have a rectangular shape.

The front and/or rear of the information sheet 500 may have a different shape from the front of the intermediate body 120.

For example, the first middle front 120a may have a rectangular shape, and the front and/or back of the information sheet 500 may have a circular, oval, or polygonal shape. Alternatively, the front and/or back of the information sheet 500 may form various shapes such as people, animals, clouds, etc.

As described above, the information sheet 500 can create aesthetics through various colors and shapes. Therefore, the interior effect of the information sheet 500 can be maximized. The display effect of the shoes (S) can be improved by creating various aesthetics of the information sheet (500).

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

Therefore, even if the information sheet 500 is coupled or not coupled to the front of the intermediate body 120, the light of the first light 410 and the second light 420 reflected from the rear of the receiving space 10 is the shoe (S ) can be conveyed in the same or similar way to the viewer's field of view. Therefore, even if the information sheet 500 is coupled to the front of the intermediate body 120 or not, the receiving space 10 can create a certain aesthetic sense based on light.

The information sheet 500 may literally mean a sheet containing information. Information can refer to a broad set of symbols, such as letters, shapes, or images. As an example, the information sheet 500 may be a sheet on which photos, pictures, or text are printed.

The information sheet 500 may be exposed to the field of view of a person looking at the shoes (S) accommodated in the shoe manager (1). Therefore, the user of the shoe manager 1 can display photos and pictures on the rear of the receiving space 10 by attaching the information sheet 500 to the front of the intermediate body 120.

Information sheet 500 may include one or more magnets 540. A concave portion 521 (hereinafter referred to as a ‘concave portion’) may be formed on the rear of the information sheet 500. A plurality of concave portions 521 may be formed along the edge of the information sheet 500. The permanent magnet 540 may be inserted into the concave portion 521. The magnet 540 may form an attractive force using magnetic force with the magnetic plate 127 provided in the intermediate body 120.

Figure 11 is a perspective view of the shoe care device 1 according to an embodiment of the present invention as seen from the back.

FIG. 12 is a perspective view showing the first external cabinet 136 and the second external cabinet 125 separated from the main body of the shoe care device 1 of FIG. 1A.

The main body 100 may include an upper body 130. The upper body 130 may be located on the upper side of the receiving space 10. The upper body 130 may form an upper space 130a inside which the accommodation space 10 and the gas flow are disconnected. The upper space 130a may have a hexahedral shape in which the lengths in the first direction (X) and the second direction (Y) are longer than the length in the third direction (Z).

The upper body 130 may include a first internal cabinet 135 and a first external cabinet 136. The first internal cabinet 135 and the first external cabinet 136 may together form an upper space 130a.

The first internal cabinet 135 may have a rectangular box shape open upward. The first internal cabinet 135 may be provided with an air passage 300 connected to the accommodation space 10 (see FIG. 1B). The passage cover 135e may close the upper opening of the air passage 300. . The first internal cabinet 135 may include an upper and lower plate 135a.

The upper and lower plates 135a may divide the receiving space 10 and the upper space 130a. The lower surface of the upper and lower plates 135a may form the upper surface of the receiving space 10. The upper surface of the upper and lower plates 135a may form the bottom of the upper space 130a. The upper and lower plates 135a may form a wide plate shape in the horizontal direction.

The blower 330 is configured to circulate the air in the receiving space 10. The blower 330 and the air passage 300 may be provided on the upper surface of the upper and lower plates 135a.

The blower 330 may include a fan and a fan housing 332. A fan may be provided inside the fan housing 332. The fan can pump air through the rotating movement of the impeller. The fan housing 332 may form part of the air passage 300.

The heating unit 340 may be configured to heat the air in the receiving space 10 directly or indirectly. The heating unit 340 may be disposed in the main body 100. The heating unit 340 may be disposed in the air passage 300.

As shown in FIG. 2B, an inlet 310 and an outlet 320 may be formed in the upper and lower plates 135a.

Air in the receiving space 10 may be sucked into the air passage 300 through the intake port 310. The air in the air passage 300 may be discharged into the receiving space 10 through the discharge port 320. Therefore, the air forcefully blown by the blower 330 can circulate through the receiving space 10 and the air passage 300.

The first light 410 may radiate light to the upper surface of the turntable 230 on which the shoes S are placed along an extension of the vertical axis 231. The second lighting 420 may be configured to illuminate the front of the intermediate body 120 from behind the first lighting 410. The first light 410 and the second light 420 may be coupled to the upper and lower plates 135a.

The control unit 600 may be coupled to the upper and lower plates 135a.

The intermediate body 120 may include a second inner cabinet 124 and a second outer cabinet 125. The first external cabinet 136 and the second external cabinet 125 may be coupled to the second internal cabinet 124 by a plurality of bolts 126b.

The second internal cabinet 124 may include a magnetic plate 127 and a resin panel 126.

The resin panel 126 may form the rear of the receiving space. The magnetic plate 127 may be coupled to the rear of the resin panel 126.

Since the upper body 130 is a type of cantilever structure that protrudes from the middle body 120, if the middle body 120 does not properly support the upper body 130, the front end of the upper body 130 may sag, etc. Problems may arise.

The shoe care device 1 according to an embodiment of the present invention has a relatively high density magnetic plate 127 coupled to the rear of a relatively low density resin panel 126, so that the second internal cabinet 124 The center of gravity is located behind the resin panel 126, which can serve as a factor in preventing the problem of the front end of the upper body 130 sagging.

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. As an example, the magnetic plate 127 may be made of iron, cobalt, nickel, and alloys thereof. Therefore, the magnetic plate 127 can form an attractive force due to magnetic force with the permanent magnet 540 coupled to the information sheet 500.

The first inner cabinet 135 and the second inner cabinet 124 may be coupled to the frame body 800. The frame body 800 may be a component that forms the framework of the main body 100. The strength of the main body 100 can be reinforced by the frame body 800.

The frame body 800 is a part that is coupled to the main body 100 and supports the main body 100 in a shape that connects the upper, lower, and rear surfaces of the main body 100, and is a body with relatively weak rigidity in terms of structure. Each connection part of (100) can be reinforced.

As described above, in order for the mobile body 200 to slide with respect to the main body 100, the front surface of the main body 100 needs to be opened to an extent corresponding to the shape of the mobile body 200. Therefore, the main body 100 must be structured to properly support the load applied to the open front surface from parts other than the front surface.

However, since the main body 100 has various components arranged inside it and it is impossible to make it infinitely large in size or rigidity, it is necessary to reinforce structurally weak parts with separate reinforcing members.

In particular, when the main body 100 is formed in a shape with an open front surface, it is necessary to support the load applied to the front surface from the remaining upper, lower, and rear surfaces, so each connection part of these parts must be reinforced. It may be desirable to do so.

In this way, in the shoe care device 1 according to this embodiment, the frame body 800 is coupled to the main body 100 in a shape that connects the upper surface, lower surface, and rear surface of the main body 100 to each other. ), the shoe care device 1 can be maintained in a stable state by reinforcing structurally weak parts of the main body 100.

In the shoe care device 1 according to an embodiment of the present invention, the frame body 800 includes an upper frame 830 coupled to the upper body 130, a lower frame 810 coupled to the lower body 110, and an upper It may include an intermediate frame 820 that connects the rear side of the frame 830 and the lower frame 810 and is coupled to the intermediate body 120.

A plurality of bosses 126a each having female threads may protrude backward from the rear of the resin panel 126. Therefore, the intermediate frame 820 can be fastened to the boss 126a by the bolt 126b.

The main body 100, which is a combination of the lower body 110, the middle body 120, and the upper body 130, is formed in a U-shape when viewed from the side, and this main body 100 is the shape of the shoe manager 1 in three-dimensional space. It can be made of 3 sides.

Accordingly, the upper body 130 and the lower body 110 are formed in a shape that protrudes forward from the middle body 120, so the front ends of the upper body 130 and the lower body 110 have a structure for supporting the load. may in fact not exist.

In particular, given that the upper body 130 is a type of cantilever structure that protrudes from the middle body 120, if the middle body 120 does not properly support the upper body 130, the front end of the upper body 130 may sag. Problems such as these may occur.

In this case, since there are structural limitations in supporting the upper body 130 only with the middle body 120, the connection portion between the lower body 110 and the middle body 120 is reinforced through the frame body 800. , it may be desirable to simultaneously reinforce the middle body 120 and the upper body 130 through the frame body 800.

Therefore, the upper body 130, lower body 110, and middle body 120 of the main body 100 are connected through the upper frame 830, lower frame 810, and middle frame 820 of the frame body 800. It may be desirable to provide reinforcement through interconnecting structures.

That is, the frame body 800 is also formed in a U-shape when viewed from the side, so that weak areas in the structure of the U-shaped main body 100 can be strengthened.

In this way, the shoe care device 1 according to this embodiment includes the frame body 800, the upper frame 830, the lower frame 810, and the middle frame 820, so the upper body 130, The weak portion of the main body 100 can be strengthened by connecting the lower body 110 and the middle body 120 to each other.

In the shoe care machine 1 according to an embodiment of the present invention, the upper frame 830, the lower frame 810, and the middle frame 820 may be formed by bending a single member extending in the longitudinal direction.

The shoe care machine 1 according to this embodiment bends one member in which the frame body 800, which includes the upper frame 830, the lower frame 810, and the middle frame 820, is formed to extend in the longitudinal direction. Therefore, it is possible to facilitate the manufacture of the frame body 800 and also minimize the cut surface of the frame body 800 corresponding to the reinforcing member.

In the shoe care device 1 according to an embodiment of the present invention, the frame body 800 may be disposed inside the main body 100. Since the frame body 800 is arranged not to be exposed to the outside, exposure of members not directly related to the function of the shoe care device 1 can be minimized to provide visual aesthetics.

In order to reinforce vulnerable parts of the main body 100, it may be desirable to arrange the frame body 800 on the entire surface of the main body 100, but this structure is uneconomical and has the risk of increasing the load of the shoe care device 1. there is.

Therefore, it can be said that arranging the first frame body (800A) and the second frame body (800B) at predetermined intervals within the range that can ensure structural stability is most effective when considering structural rigidity and product economics. .

In this case, in order to prevent deformation such as structural distortion due to imbalance in the rigidity of the shoe care device 1, the first frame body 800A and the second frame body 800B are arranged symmetrically along the left and right directions of the main body 100. It may be desirable to be

In this way, in the shoe care device 1 according to this embodiment, a plurality of frame bodies 800 are arranged along the left and right directions of the main body 100 to reinforce the main body 100, thereby providing structural reinforcement to the main body 100. This can be done more uniformly and stably.

The second internal cabinet can be manufactured by integrating the magnetic plate 127 and the resin panel 126 through insert injection.

Insert injection is a method of inserting a high-strength metal insert such as steel into an injection mold and then injecting polymer resin to produce a molded product in which the insert and plastic are integrated.

The insert injection method is carried out in the following order. First, the insert product is inserted into the injection mold. Next, the molten resin in the injection molding machine cylinder is filled into the mold and the insert product is covered with the molten resin. After cooling and solidifying the molten resin over a predetermined period of time, the molded product in which the insert product and the plastic are integrated is taken out of the mold.

In the present invention, the insert product may refer to the magnetic plate 127, and the plastic may refer to the resin panel 126. The metal material and the injection polymer resin integrated by insert injection form strength and rigidity through the interfacial bonding force.

A plurality of through holes 127h may be formed in the magnetic plate 127. The bosses 126a may pass through the through holes 127h and protrude backward toward the frame body.

When integrally molding the magnetic plate 127 and the resin panel 126 by insert injection, the bosses 126a may be in close contact with one side of the through holes 127h. The bosses 126a have strength and rigidity due to the interfacial bonding force with one side of the through holes 127h.

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 weak. In this case, the information sheet 500 may be released from being attached to the first middle front 120a by various external forces such as an impact applied to the shoe care device 1.

The through holes 127h may be disposed on the left and right edges of the magnetic plate 127. Accordingly, the horizontal width of the area (120g; hereinafter referred to as 'uniform area') where the information sheet 500 and the magnetic plate 127 form a uniform magnetic force can be expanded in the left and right directions from the center of the magnetic plate 127.

The second bosses 126a2 may be formed in plural numbers. The second bosses 126a2 may pass through the second through holes 127h2 and protrude backwards.

When integrally molding the magnetic plate 127 and the resin panel 126 by insert injection, the first bosses 126a1 may be in close contact with one side of the first through holes 127h1.

Here, one side of the first through holes 127h1 may mean a side opposite to the second boss 126a2 with respect to the first boss 126a1. Additionally, one side of the first through holes 127h1 may refer to a side opposite to the other first boss 126a1 based on one first boss 126a1. The first bosses 126a1 form strength and rigidity by interfacial bonding force with one side of the first through holes 127h1.

Additionally, when the magnetic plate 127 and the resin panel 126 are integrated and molded by insert injection, the second bosses 126a2 may be in close contact with one side of the second through holes 127h2.

Here, one side of the second through-holes 127h2 may mean a side opposite to the first boss 126a1 with respect to the second boss 126a2.

That is, the through hole 127h may be extended to form a path through which the inclined core for forming the boss 126a falls out when the injection mold is opened. Since the inclined core is a widely known technology in the field of injection mold manufacturing, detailed description thereof will be omitted.

The through hole 127h is extended by an inclined core for forming the boss 126a, and may extend long above or below the boss 126a. Therefore, even if the through hole 127h is extended, the horizontal width of the uniform area 120g can be maintained.

Accordingly, even if the through hole 127h is extended by the inclined core for forming the boss 126a, the horizontal width of the uniform area 120g can be expanded in the left and right directions from the center of the magnetic plate 127. Therefore, even if various external forces such as shock are applied to the shoe care device 1, the information sheet 500 can firmly maintain its attachment to the first middle front 120a.
