Description

FIELD OF THE INVENTION

The present invention relates to a baby care item, or more specifically, to a baby care item mounted on a baby chair that can prevent objects from falling on the ground to improve baby hygiene.

BACKGROUND OF THE INVENTION

Since a baby's immune system is not fully developed, it is essential to clean and sanitize baby objects and environments to maintain hygiene. Exposure to dirt, pet dander, and household germs may affect babies to develop serious diseases.

Meanwhile, a baby chair is a specialized chair with a small tray and widely used for feeding babies. While babies sit on the baby chairs, it is very common that they drop their toys or spoons on the floor or ground. Unless dropped items are sanitized to remove the germs every time, they are likely to be sources of germs which can infect babies. Accordingly, it is necessary to prevent the baby's objects from falling on the floor.

In order to solve the problem mentioned above, Applicant of the present invention has devised the U.S. Pat. No. 10,470,500, titled “Protection Net on Which a Purse or a Bib Is Attached,” filed on Nov. 12, 2019. The protection net disclosed on this patent is configured to prevent a baby's objects from falling on the ground by fixing one side thereof to a baby chair and the other side thereof to a separate table which may be located in front of the baby.

Although the structure disclosed on this patent can prevent objects' falling to the ground, it can be installed and used only when the baby chair is in front of the table. Therefore, Applicant has devised a novel protection net that can be fixed only to a baby chair and used independently without using other furniture or supports.

FIG. 3 is a perspective view schematically illustrating a plurality of net supporting part 101 of the protection net apparatus 10 of FIG. 1 in a fixed state to a tray CT of a baby chair C. FIGS. 4 and 5 are magnified bottom perspective views from the outside and the inside, each illustrating a clamp portion 101F of the net supporting part 101 of FIG. 1 in a fixed state to the tray CT of the baby chair C. FIGS. 6A and 6B are cross sectional views illustrating the clamp portion 101F and the supporting rod portion 101S of FIG. 1 in a fixed state to the tray CT of the baby chair C. FIG. 6A shows an angle of the supporting rod portion 101S from the clamp portion 101F. FIG. 6B shows a length of the supporting rod portion 101S from clamp portion 101F.

Referring to FIGS. 3 to 6B, the net supporting part 101 includes: a clamp portion 101F fixing the net supporting part 101 to the tray CT and a supporting rod portion 101S coupled to the clamp portion 101F and extending outwards with a certain angle.

The clamp portion 101F may include: a body 101F2 having a U shape and clamping the tray CT through an opening of the U shape; a handle 101F3 connected to a bottom of the body 101F2 and protruding from the body 101F2 in an opposite direction to the opening of the U shape; and a base portion 101F1 extended from a bottom end of the supporting rod portion 101S, connected to a top of the body 101F2, protruding from the body 101F2 toward in a same direction as the opening, and resting against a top surface of the tray CT to provide a fixing force to the supporting rod portion 101S.

In some embodiments, the tray CT of the baby chair C may have a top surface portion on which food or objects are laid out and a side wall portion CTW protruding downwards from the edge of the top surface portion of the tray CT. In this case, the body 101F2 of the clamp portion 101F may clamp the side wall portion CTW from the bottom of the side wall portion CTW in a direction where the handle 101F3 is positioned to be an inner side of the wall portion CTW and the base portion 101F1 is positioned to be an outer side of the wall portion CTW.

In this case, as shown in FIG. 6A, the base portion 101F1 may be configured to be substantially parallel to a surface of the side wall portion CTW, and an angle θ1 between the base portion 101F1 and the supporting rod portion 101S ranges between 0 and 90 degree. Preferably, the angle θ1 between the base portion 101F1 and the supporting rod portion 101S may be approximately 20 degree, and thus, an angle between the supporting rod portion 101S and the ground may be approximately 70 degree. Accordingly, the net part 103 may be formed like an extended area or an outwardly inclined wall surrounding the edge of the tray CT.

In FIG. 6A, the angle θ1 of the supporting rod portion 101S is illustrated to be approximately 20 degree from the base portion 101F1, but the present invention is not limited thereto. The angle θ2 between the base portion 101F1 and the supporting rod portion 101S of the net supporting part 101 may be bigger or smaller than 20 degree as the net supporting part 201 shown in FIG. 6A.

Meanwhile, a length of the supporting rod portion 101S may range from 3.0 inches to 10.0 inches but is not limited thereto. The length of the supporting rod portion 101S may be chosen by need of a user and may be shorter than 3.0 inches or longer than 10.0 inches.

The base portion 101F1 and the supporting rod portion 101S may be one body 101F2 made of stainless steel. The base portion 101F1 and the supporting rod portion 101S may be manufactured by bending a piece of stainless steel line or wire to form a specific angle between the base portion 101F1 and the supporting rod portion 101S, such as a first angle θ1 or a second angle θ2 shown in FIG. 6. Meanwhile, the body 101F2 and the handle 101F3 may be obtained from a commercial binder clip of which one handle is removed. In this case, the base portion 101F1 is connected to a space where the removed handle 101F3 had been connected.

As mentioned above, the protection net apparatus 10 may have a plurality of the net supporting parts 10, and the net supporting parts 101 may be at least three. In this case, at least one of the net supporting part 101 may be located on a front portion of the tray CT, and at least two of the net supporting part 101 are respectively located on both side portions of the tray CT to improve fall protection effects.

In some embodiments, at least one of the plurality of the net supporting parts 101 has different shapes from the others with respect to at least one of an angle of the supporting rod portion 101S from the clamp portion 101F and a length of the supporting rod portion 101S.

For example, an angle between the base portion 101F1 and the supporting rod portion 101S of the net supporting part 101 located on a front portion of the tray CT may be different from that between the base portion 101F1 and the supporting rod portion 101S of the net supporting part 101 located on a side portion of the tray CT.

For example, a length of the supporting rod portion 101S of the net supporting part 101 located on a front side wall portion CTW1 may be longer than that of the supporting rod portion 101S of the net supporting part 101 located on a lateral side wall portion CTW2, but the present invention is not limited thereto.

Meanwhile, the clamp portion 101F described above is one embodiment of the present invention and is not limited thereto. The clamp portion 101F may be other structures having a clamping function and a supporting function with a fixable support.

FIGS. 7A and 7B are front and bottom views schematically illustrating a net part 103 of the protection net apparatus 10 of FIG. 1 in a state where the net part 103 is spread out on a plane. FIG. 8 is a magnified front view illustrating a M portion of the protection net apparatus 10 of FIG. 1. FIGS. 9A and 9B are magnified front and cross sectional views illustrating the receiving pocket 103R of the net part 103 and the supporting rod portion 101S of the net supporting part 101 of the protection net apparatus 10 of FIG. 1 in a state before the supporting rod portion 101S is received into the receiving pocket 103R. FIGS. 10A and 10B are magnified front and cross sectional views illustrating the receiving pocket 103R and the supporting rod portion 101S in a state when the supporting rod portion 101S is received into the receiving pocket 103R.

Referring to FIGS. 7A and 7B, the net part 103 including: a net 130N; the receiving pocket 103R attached to a surface of the net 130N at an outer edge portion of the net 103N; and an edge member 103E attached to an edge portion of the net 130N. The net part 103 is mounted on the top end of the supporting rod portion 101S by engaging the top end of the supporting rod portion 101S with the receiving pocket 103R and is spread from the supporting rod portion 101S to the tray CT.

Specifically, the net 130N includes an edge having an inner edge 103S1, an outer edge 103S2 located on an opposite side of the inner edge 103S1, and lateral edges 103S3 each connecting between ends of the inner edge 103S1 and the outer edge 103S2. Referring to FIG. 8 together, the net 130N is folded multiple times along the edge portion in a substantially perpendicular direction to the edge 103S1, 103S2, 103S3 and has net wrinkles 103W. As shown in FIG. 8, some portions of the net 103N may be overlapped by the folds.

Referring to FIGS. 9A to 10B together, the receiving pocket 103R is attached to a surface of the net 130N on the outer edge portion adjacent to the outer edge 103S2 in a direction that an opening of the receiving pocket 103R heads toward the inner edge 103S1. The receiving pocket 103R receives the top end of the supporting rod portion 101S through its opening.

The edge member 103E is attached to the edge portion of the net 130N along the edge 103S1, 103S2, 103S3 in a state where the edge portion is folded in a substantially perpendicular direction to the edge 103S1, 103S2, 103S3. In some embodiments, the edge member 103E is made of a rubber based material having elasticity. The edge member 103E made of a rubber based material can be easily stretched to increase a space of the net part 103 when objects are caught on the net part 103, thereby providing improved objects fall prevention effects.

As the net 130N is folded multiple times, a first length of the edge 103S1, 103S2, 103S3 of the net 130N in a folded state is same as that of the edge member 103E, and a second length of the edge 103S1, 103S2, 103S3 of the net 130N in an unfolded state is longer than that of the edge member 103E. Thus, a first area of the net 130N in the folded state is substantially same as that defined by the inner edge member 103E1, the outer edge member 103E2, and the lateral edge members 103E3, and a second area of the net 130N in the unfolded state is larger than that defined by the inner edge member 103E1, the outer edge member 103E2, and the lateral edge members 103E3. Accordingly, the net part 103 can have an enough space when receiving dropped or thrown objects.

In some embodiments, where the edge member 103E includes an inner edge member 103E1 attached to an inner edge portion adjacent to the inner edge 103S1, an outer edge member 103E2 attached to the outer edge portion adjacent to the outer edge 103E2, and lateral edge members 103E3 each attached to a lateral edge portion adjacent to the lateral edge 103S3, a length of the outer edge member 103E2 may be longer than that of the inner edge member 103E1, as shown in FIGS. 7A and 11B. Accordingly, the net part 103 may have a semi-funnel shape, which further improves object fall prevention effects in that the net part 103 can receive the objects dropped from front and lateral sides.

FIGS. 11A and 11B are drawings schematically illustrating a method of manufacturing the net part 103 of the protection net apparatus 10 according to an embodiment of the present invention.

Referring to FIGS. 7A, 7B, 11A, and 11B, the net 103N is manufactured by using the net fabric p103N, the edge member 103E, and the receiving pocket 103R.

The net fabric p103N may have a rectangular shape with an inner edge p103S1, an outer edge p103S2 located on an opposite side of the inner edge p103S1, and lateral edges p103S3 each connecting between ends of the inner edge p103S1 and the outer edge p103S2. The inner and the outer edge p103S1, p103S2 may have a same length p103NL, and the third and the fourth edge p103S3 may have a same length p103NW which is shorter than the length P103NL.

In FIGS. 11A and 11B, the inner and the outer edge p103S1, p103S2 of the net fabric p103N have the same length, and the lateral edges p103S3 of the net fabric p103N have the same length. However, the present invention is not limited thereto, and the inner and the outer edge p103S1, p103S2 may have different lengths, and the lateral edges p103S3 may have different lengths from each other.

The net fabric p103N may be any fabric, cloth, or textile in which the yarns are fused, looped, or knotted at their intersections. In some embodiments, the net fabric p103N may be any general fabric, cloth, or textile having multiple holes. In this case, the diameter of each hole and the density of the holes may be selected enough to prevent objects from passing therethrough and at the same time, allow a baby to see the outside environment through the net 103N or persons outside the net 103N to see the baby surrounded by the protection net apparatus 10.

After preparing the net fabric p103N, the edge portion of the net fabric p103N may be folded multiple times along the inner edge p103S1, an outer edge p103S2, and lateral edges p103S3. In this case, the edge portion near the inner edge p103S1 may be folded more than that of the outer edge p103S2 but is not limited thereto.

In a state where the edge portion of the net fabric p103N is folded along the edge p103S1, p103S2, p103S3, an inner edge member 103E1 of the edge member 103E may be attached to an inner edge portion adjacent to the inner edge p103S1; an outer edge member 103E2 of the edge member 103E may be attached to the outer edge portion adjacent to the outer edge p103S2; and each of lateral edge members 103E3 of the edge member 103E may be attached to a lateral edge portion adjacent to the lateral edge p103S3. By attaching the edge member 103E to the edge portion of the net fabric p103N in a folded state, net wrinkles 103W formed by the folds are fixed. In other words, the folded form of the net fabric p103N can be fixed. Accordingly, when objects are dropped or thrown to the net part 103, the net wrinkles 103W are unfolded by the weights of the objects, and the net part 103 has an enough a space to receive the objects. Therefore, the objects that a baby drops can be effectively prevented from falling to the floor or ground.

In some embodiments, the inner edge member 103E1 may be shorter than the outer edge member 103E2, and thus, the inner edge portion corresponding to the inner edge 103S1 may have more net wrinkles 103W than the outer edge portion corresponding to the outer edge 103S2, but the present invention is not limited thereto.

As described above, the edge members 103E1, 103E2, 103E3 may be made of a rubber based material with elasticity but are not limited thereto. The edge member 103E1, 103E2, 103E3 may be made of general fabric, cloth, or textile.

Referring to FIG. 7A again, after attaching the edge members 103E1, 103E2, 103E3 to the edge portion of the net fabric p103N, the receiving pocket 103R are attached to the edge portion adjacent to the outer edge 103S2 in a direction that an opening of the receiving pocket 103R heads toward the inner edge 103S1. Accordingly, the net part 103 of the protection net apparatus 10 is manufactured.

Referring to FIGS. 1 and 2 again, the connecting part 105 includes a string 105S each end connected to each of the lateral edges of the net and provides tension to the net 103N by being installed behind a back of the baby chair C that is positioned opposite to the tray CT of the baby chair C.

In some embodiments, the string 105S may include two strings 105S of which each of one ends is connected to each of the lateral edges of the net 103N, and the connecting part 105 may further include a pair of coupling members 105F such as buckles, and each of the coupling member 105F may be connected to each of the other ends of the two strings 105S.

FIG. 12 is a drawing schematically illustrating a process of mounting the net part 103 to the net supporting part 101 of the protection net apparatus 10 according to an embodiment of the present invention.

Referring to FIGS. 3 and 12, the protection net apparatus 10 may be installed according to the steps of: fixing the plurality of net supporting parts 101 to the different positions of the edge of the tray CT of the baby chair C first by using the clamping position 101F; then mounting the net part 103 on the supporting rod portion 101S by engaging the receiving pocket 103R with the supporting rod portion 101S; and then pulling the string 105S connected to the net part 103 to the back of the baby chair C and fastening the coupling members 105F.

FIG. 13 is a drawing schematically illustrating how the protection net apparatus 10 prevents the baby's items from falling on the floor according to an embodiment of the present invention.

Referring to FIG. 13, when a baby sitting on the baby chair on which the protection net apparatus 10 is installed throws or drops his or her items such as toys or spoons, the protection net apparatus 10 can provide a space to receive them and thus can prevent the objects from falling onto the ground and thus being contaminated with dirt on the floor.
