DETAILED DESCRIPTION OF THE INVENTION

The attached drawings for illustrating exemplary embodiments of the present invention are referred to in order to gain a sufficient understanding of the present invention, the merits thereof, and the objectives accomplished by the implementation of the present invention.

Hereinafter, the present invention will be described in detail by explaining exemplary embodiments of the invention with reference to the attached drawings. Like reference numerals in the drawings denote like elements.

FIG. 1 is a perspective view of a car seat footrest 100 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the car seat footrest 100 of FIG. 1.

Referring to FIGS. 1 and 2, the car seat footrest 100 may include a coupling plate 110, a supporting plate 130, and at least one guide bar 150.

The coupling plate 110 may have a plate shape so as to be coupled between a vehicle seat and a car seat coupled thereto and include at least one first coupling hole H1 formed on a surface of the coupling plate 110. In general, in order to install a carseat on a vehicle seat, the car seat may be positioned and the car seat may be tied by a seat belt of the vehicle so as to be fixed to the vehicle. Likewise, when the car seat is positioned on the vehicle seat, the coupling plate 110 may be positioned between the vehicle seat and the car seat to be fixed. That is, when the coupling plate 110 may be positioned on the vehicle seat, the car seat may be positioned on the coupling plate 110, and then the car seat is tied by the seat belt so as to be fixed, a pressure of the car seat toward the vehicle seat may be propagated to the coupling plate 110 and the car seat footrest 100 may be fixed. The coupling plate 110 may be formed with various shapes and various materials and may not be limited to the shape of FIGS. 1 and 2 as long as the coupling plate 110 is fixedly coupled between the car seat and the vehicle seat.

The supporting plate 130 may have a plate shape so as to support the feet of a child who sits on the car seat and include at least one second coupling hole H2 on a surface of the supporting plate 130. The supporting plate 130 may be a portion for supporting the feet of the child who sits on the car seat, may be formed with various shapes and various materials, and may not be limited to the shape of FIGS. 1 and 2.

The guide bar 150 may have a column shape and may be detachably coupled into the first coupling hole H1 and the second coupling hole H2. FIG. 1 illustrates the embodiment in which an upper end portion of the guide bar 150 is fixedly inserted into the first coupling hole H1 formed in the coupling plate 110 and a lower end portion of the guide bar 150 is fixedly inserted into the second coupling hole H2 formed in the supporting plate 130. However, the present invention is not limited thereto. The guide bar 150 may be inserted into or separated from the first coupling hole H1 and the second coupling hole H2. Accordingly, oppositely to the embodiment of FIG. 1, a lower end portion of the guide bar 150 is fixedly inserted into the first coupling hole H1 and an upper end portion of the guide bar 150 is fixedly inserted into the second coupling hole H2 so as to position the supporting plate 130 above the coupling plate 110 (refer to FIG. 10). FIGS. 1 and 2 illustrate the embodiment in which two guide bars 150 are inserted into the first coupling hole H1 and the second coupling hole H2 that respectively correspond thereto. However, the present invention is not limited thereto. A different number of guide bars 150 may be fixedly inserted into the first coupling hole H1 and the second coupling hole H2. Accordingly, the number of first coupling holes H1 and the number of second coupling holes H2 may be greater than at least the number of the guide bars 150.

Since the supporting plate 130 may be rotatable, the supporting plate 130 with adjusted inclination may be fixedly coupled to the guide bar 150. The inclination of the supporting plate 130 may be adjusted for comfortability of the child who sits on the car seat or according to convenience of the child such that the child may comfortably and safely sit on the car seat. The supporting plate 130 may include a supporting member 133, a fixing member 135, and an inclination adjuster 137 as an embodiment of components for adjusting the inclination of the supporting plate 130, which will be described in more detail with reference to FIGS. 3 and 4.

In addition, the coupling plate 110 or the supporting plate 130 may be fixedly coupled at a specific location or specific height of the guide bar 150. That is, the first coupling hole H1 and the second coupling hole H2 are each formed as a through hole, and the guide bar 150 is inserted into the first coupling hole H1 or the second coupling hole H2 up to a specific location of the guide bar 150 so as to fixedly couple the coupling plate 110 or the supporting plate 130 and the guide bar 150. Thus, a location or height of the guide bar 150 at which the coupling plate 110 or the supporting plate 130 is coupled to the guide bar 150 may be adjusted. The car seat footrest 100 may further include a first location adjuster 115 and a second location adjuster 139 as components for adjusting a coupling location of the coupling plate 110 or the supporting plate 130. The second location adjuster 139 may fix the supporting plate 130 to the guide bar 150 while the guide bar 150 is inserted into the second coupling hole H2 and a coupling location of the supporting plate 130 and the guide bar 150 is adjusted. An embodiment of the first location adjuster 115 and the second location adjuster 139 will be described in more detail with reference to FIGS. 5 and 6.

FIG. 3 is a view of the inclination adjuster 137 for adjusting inclination of the supporting plate 130 of FIG. 1, and FIG. 4 is a view of the inclination adjuster 137 viewed from a different direction from in FIG. 3.

Referring to FIGS. 1 to 4, the supporting plate 130 may include the supporting member 133, the fixing member 135, and the inclination adjuster 137.

The supporting member 133 may have a plate shape so as to support the feet of a child who sits on the car seat. The fixing member 135 may include at least one second coupling hole H2 formed therein and may be coupled to at least one guide bar 150. The inclination adjuster 137 may rotatably couple the supporting member 133 in an axis direction of the fixing member 135. The inclination adjuster 137 may couple the supporting member 133 and the fixing member 135 using various configurations. Among these, one embodiment according to the present invention will be described with reference to FIGS. 3 and 4.

The inclination adjuster 137 may include an inclination adjusting gear 310 and an inclination adjusting switch 340. The inclination adjusting gear 310 may be coupled to a first coupling groove 320 formed in each external side of the fixing member 135 or a second coupling groove 350 formed in each internal side of the supporting member 133. The inclination adjusting gear 310 may be saw-toothed like in the embodiment illustrated in FIGS. 3 and 4. However, the present invention is not limited thereto, and the inclination adjusting gear 310 may have other shapes. The first coupling groove 320 or the second coupling groove 350 may have the same shape as that of the inclination adjusting gear 310.

The inclination adjusting switch 340 may be elastically coupled to the inclination adjusting gear 310 and may control the inclination adjusting gear 310 to be inserted into or separated from the second coupling groove 350. In order to elastically couple the inclination adjusting switch 340 and the inclination adjusting gear 310, an elastic body 330 may be coupled between the inclination adjusting gear 310 and the fixing member 135.

For example, when a pressure is applied to the inclination adjusting switch 340 (when a force is applied in a direction toward the fixing member 135 from the supporting member 133 in the embodiment of FIGS. 3 and 4), the inclination adjusting gear 310 may be separated from the second coupling groove 350. That is, when the inclination adjusting gear 310 is separated from the second coupling groove 350, the supporting member 133 may be freely rotatable, and thus, a user may adjust the supporting member 133 to be positioned at desired inclination.

When the inclination of the supporting member 133 is adjusted and then the pressure applied to the inclination adjusting switch 340 is removed (when the force applied in the direction toward the fixing member 135 from the supporting member 133 is removed in the embodiment of FIGS. 3 and 4), the inclination adjusting gear 310 may be coupled to the second coupling groove 350 according to restoration force. That is, when the inclination adjusting gear 310 is coupled to the second coupling groove 350 according to the restoration force of the elastic body 330, the supporting member 133 is fixed, and thus the user may fix and use the supporting member 133 that is adjusted with desired inclination. For example, when the inclination adjusting gear 310 is saw-toothed, as the number of saw teeth increases, the inclination of the supporting member 133 may be adjusted in more detail.

The inclination adjuster 137 of the car seat footrest 100 according to an embodiment of the present invention may not be limited to the embodiment of FIGS. 3 and 4 and may have various different structures as long as the inclination adjuster 137 adjusts and fixes the inclination of the supporting member 133.

FIG. 5 is a view of the first location adjuster 115 illustrated in FIG. 1 according to an embodiment of the present invention.

Referring to FIGS. 1 to 5, the first location adjuster 115 may include an insertion portion 510 and a coupling portion 520 that are formed on the coupling plate 110.

The insertion portion 510 may extend in one direction or two opposite directions from the first coupling hole H1 formed in the coupling plate 110, include a hollow formed in the insertion portion 510 so as to insert the guide bar 150 into the insertion portion 510, and include at least one through hole H3 formed on an outer circumference surface of the insertion portion 510. That is, the insertion portion 510 may protrude to extend from the first coupling hole H1 in a direction toward the supporting plate 130 from the coupling plate 110. The guide bar 150 may include a plurality of holes H4 formed in an outer circumference surface with a column shape. In addition, the guide bar 150 and the coupling plate 110 may be fixedly coupled by inserting the coupling portion 520 into the hole H3 of the insertion portion 510 and the hole H4 of the guide bar 150 while the guide bar 150 is inserted into the insertion portion 510. That is, the first location adjuster 115 may adjust the location or height of the coupling plate 110 to fixedly couple the coupling plate 110 at a specific location of the guide bar 150.

The first location adjuster 115 of the car seat footrest 100 according to an embodiment of the present invention is not limited to the embodiment of FIG. 5 and may have various configurations as long as the first location adjuster 115 may adjust and fix the location or height of the coupling plate 110. For example, simply, the coupling plate 110 and the guide bar 150 may be fixedly coupled while the guide bar 150 is press-fit into the first coupling hole H1 and a coupling location of the coupling plate 110 and the guide bar 150 is adjusted. In this case, the hole H4 does not have to be formed in an outer circumference surface of the guide bar 150, and the first location adjuster 115 described with reference to FIG. 5 is not needed also.

FIG. 6 is a view of the second location adjuster 139 illustrated in FIG. 1 according to an embodiment of the present invention.

Referring to FIGS. 1 to 6, the second location adjuster 139 may include at least one supporting plate 610, at least one location adjuster 620, a controller 630, and a frame 640 and may be formed on the fixing member 135 of the supporting plate 130.

The guide bar 150 may include a plurality of holes H4 formed on an outer circumference surface with a column shape. At least one supporting plate 610 may be fixedly coupled to the frame 640. Although FIG. 6 illustrates the case in which at least one supporting plate 610 is fixedly coupled to a bottom surface of the frame 640, the present invention is not limited thereto. Alternatively, the supporting plate 610 may be fixedly coupled to an internal side of a top surface of the frame 640. At least one location adjuster 620 may be elastically coupled to the supporting plate 610 and may include a protrusion 623 that is formed at one end and is inserted into or separated from the hole H4 of the guide bar 150, a finger stop 627 formed at the other end, and a handle 625 that protrudes from an upper end or lower end of the frame 640. In addition, the controller 630 may include a flange 633 on which the finger stop 627 stumbles and a switch 635 that protrudes from an upper end or lower end of the frame 640, may be elastically coupled to the frame 640 in the frame 640, and may move along an outer circumference surface of the supporting plate 610. For example, a guide groove may be formed in an outer circumference surface of the supporting plate 610, and the controller 630 may be moved along the guide groove.

For example, when the handle 625 is moved in a direction toward the supporting plate 610, the finger stop 627 may stumble on the flange 633 and the location adjuster 620 may be fixed while the protrusion 623 is separated from a hole of the guide bar 150. In this state, when a pressure is applied in a direction (a vertical direction of FIG. 6) that is not parallel to a moving direction of the handle 625, the finger stop 627 may be separated from the flange 633, and the protrusion 623 may be moved in a direction toward the guide bar 150 and inserted into the hole of the guide bar 150 according to restoration force of an elastic body, and thus the guide bar 150 and the supporting plate 130 may be fixedly coupled.

The second location adjuster 139 of the car seat footrest 100 according to an embodiment of the present invention is not limited to the embodiment of FIG. 6 and may have various different configurations as long as the second location adjuster 139 adjusts and fixes the location or height of the supporting plate 130. For example, simply, the supporting plate 130 and the guide bar 150 may be fixedly coupled while the guide bar 150 is press-fit into the second coupling hole H2 and a coupling location of the supporting plate 130 and the guide bar 150 is adjusted. In this case, the hole H4 does not have to be formed in an outer circumference surface of the guide bar 150, and the second location adjuster 139 described with reference to FIG. 6 is not needed also.

FIGS. 7 to 12 are views illustrating various states in which the car seat footrest 100 of FIG. 1 is used.

Referring to FIGS. 1 to 12, the car seat footrest 100 may be used while the location or height of the supporting plate 130 is adjusted like in an embodiment of FIG. 7 or while the inclination of the supporting plate 130 coupled to the same location as in FIG. 7 is adjusted like in an embodiment of FIG. 8 or 9. For example, when the car seat footrest 100 is coupled between a car seat and a vehicle seat, if child's feet do not have to be supported or a vehicle footing needs to be used, the supporting plate 130 may not be used like in FIG. 9.

In addition, like in an embodiment of FIG. 10, the car seat footrest 100 may be coupled and used in an opposite way to the embodiment of FIG. 1. That is, as illustrated in FIG. 10, the coupling plate 110 and the supporting plate 130 may be coupled to the guide bar 150 so as to position the supporting plate 130 above the coupling plate 110. For example, when a child sitting on the car seat is small and his or her feet are positioned higher than the vehicle seat, the car seat footrest 100 may be used like in FIG. 10. FIG. 11 illustrates the state in which the location or height of the supporting plate 130 is adjusted based on the embodiment of FIG. 10, according to an embodiment of the present invention. FIG. 12 illustrates the state in which inclination of the supporting plate 130 coupled to the same location as in the embodiment of FIG. 11 is adjusted, according to an embodiment of the present invention.

In addition to the embodiments described with reference to FIGS. 7 to 12, the car seat footrest 100 according to an embodiment of the present invention may variously adjust locations of the supporting plate 130 and the coupling plate 110 and may also variously adjust inclination of the supporting plate 130. In addition, since the coupling plate 110 and the supporting plate 130 are detachable from the guide bar 150, when the car seat footrest 100 is not used, the car seat footrest 100 may occupy a small volume by separating the coupling plate 110, the supporting plate 130, and the guide bar 150 from each other so as to be easily and conveniently kept or carried.

According to an embodiment of the present invention, a footrest for a car seat is advantageous in that feet of all age groups of children sitting on the car seat may be comfortably and safely supported by simply adjusting the height or inclination of the footrest according to the body size of the child sitting on the car seat. In addition, instead of a footrest that is used only in a specific car seat or is installed in a car seat, a footrest for a car seat according to an embodiment of the present invention may be inserted between a vehicle seat and the car seat so as to be simply installed and fixed, and thus, is advantageous in that it is not necessary to purchase a new car seat and the footrest may be used for all types of car seats.
