[0001] The present invention relates to a child seat cover that can cover almost the entire front child seat fixed to the handlebars of a bicycle or a rear child seat fixed to the rear carrier of a bicycle. The child car seat to be covered here includes those with a headrest or a sun hood provided at the top end of the backrest. [Background technology]

[0002] As is well known today, the front child car seat has a seat that is fixed to the roughly U-shaped curved part in the center of the bicycle's handlebars, a footrest that can be opened and closed and opens downwards when in use, a headrest (also called a head support) that can slide up and down is provided on the back of the seat, and a handle in front of the seat for a seated child. There are also fixed types of headrests that do not slide up and down, and types where the footrest does not open and close.

[0003] On the other hand, in the case of a rear child seat, the seat is fixed to the rear carrier of the bicycle, the foot rests are arranged on both sides of the rear wheel of the bicycle, the back of the seat is also equipped with a headrest that can slide up and down, and there is a handle in front of the seat for the child sitting in it to hold. Of course, there are also seats of this type in which the headrest is fixed and does not slide up and down.

[0004] Some of these child seats (hereinafter simply referred to as "seats") are equipped with a hood (sunshade) above the headrest. This hood is similar to that found on strollers, and consists of multiple inverted U-shaped frames that are hung from side to side and can be opened and closed like a fan when viewed from the side.Mesh fabric is stretched over these frames and can be rotated backwards to overlap and release them, or rotated forwards to pull them out and spread them out to be used as a sunshade.

[0005] The child seat covers (hereinafter simply referred to as "covers") currently on the market are mainly those that can be applied to the type of child seat that does not have a hood, and there are various types of child seat covers that can cover almost the entire seat except for the bottom surface.

[0006] The child seat cover described in the following patent document was previously proposed by the applicant of the present application, and its primary objective was to make it possible to open the entrance and exit of the cover extremely easily in an emergency. The object of the present invention is to provide a cover that takes safety into consideration so that, for example, the front part of the cover or the front window can be easily opened in the event of an emergency involving a child riding on the seat or if the bicycle falls over.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an explanatory view showing a state in which a child seat cover according to the present invention is attached to a front child seat, and the front grip portion is gripped and half of the cover is opened downward.

[0019] As shown in this figure, the child seat cover 1 according to the present invention can cover almost the entire child seat S with a hood. The child car seat S shown in this figure has a headrest H attached to the upper edge of the backrest of the seat, and a footrest provided continuously in front of the seat.

[0020] The child seat S is provided with a hood that can be attached and detached with a single touch at the upper edge of both sides of the seat. This hood can be opened and closed in the forward and backward directions by pivoting the lower ends of both legs of three roughly inverted U-shaped frames, and the downward extensions of each pivot on both sides can be attached detachably to the upper edges of both sides of the child seat S. The three frames are covered with mesh fabric, which acts as a sunshade.

[0021] The child seat cover 1 according to the present invention can cover the front child seat S almost entirely. Thus, the child seat cover 1 of the present invention is composed of two parts: a main body part 10 that covers the upper part of the child seat S (hood part, headrest part H, and backrest part) and the rear parts of both side parts of the child seat S, and a front part 20 that covers the front part and footrest part of the child seat S.

[0022] The main body 10 comprises an upper covering portion, a rear covering portion, and side covering portions on both sides. The upper covering portion covers the upper portions of the hood, headrest and backrest of the child car seat, the back covering portion covers the lower portion of the backrest of the seat and part of the bottom surface of the seat, and the side covering portions on both sides can cover the side portions of the seat and part of the bottom surface of the seat.

[0023] The side covering portions on both sides are provided with insertion portions for inserting the handle grips G of the bicycle.

[0024] A flexible and elastic annular linear member is disposed on the lower edge of the upper covering portion. The annular linear member can be disposed inside an insertion portion formed along the entire lower peripheral edge of the upper covering portion.

[0025] This annular linear member is made of POM resin, a material that is highly flexible and elastic. Alternatively, the linear member may be made of a flexible and elastic metal wire or FRP (fiber reinforced plastic).

[0026] This annular linear member allows the upper covering portion (ceiling portion) of the main body 10 to have a shape similar to that of an umbrella or a hat, and is placed and attached on the hood of the front child seat. Furthermore, two rib members are installed inside the upper covering portion so as to span the left and right directions. The presence of these rib members maintains the overall shape of the upper covering portion and matches the shape of the hood of the seat to be covered, allowing it to be placed on the hood more appropriately, covering and attaching to the hood.

[0027] The frame member is also made of a wire material made of POM resin, but its diameter is thinner than that of the annular linear member. However, this frame member can also be implemented without the wire material, because it can be manufactured by using a shape-retaining material as the material for the upper covering portion.

[0028] Although not shown in the figure, a plurality of air exhaust holes are provided above the rear surface of the upper covering part of the main body 10, and a covering sheet is provided above these air exhaust holes. This covering sheet serves as a rain cover.

[0029] A front portion 20 of the main body, which will be described next, is detachably engaged with the front opening of the main body 10 by slide fasteners 10f, 20f. The upper portions of the front covering portion 21 and both side covering portions 22 of this front portion 20 are formed from a transparent material such as PVC, and a rib member 23 is provided laterally at approximately the center of the front covering portion 21 and the side covering portion 22, so that the front portion 20 can maintain an external shape that bulges outward appropriately. However, it is also possible to manufacture the device without using the bone member 23.

[0030] This front portion 20 can cover the front portion of the child seat, the lower foot rest portion, and the front portions of both side portions, and can be engaged and disengaged with the front opening of the main body portion 10 described above by slide fasteners 10f, 20f. That is, slide fasteners 20f are provided on the upper edge and both side edges of the front part 20, and correspondingly, slide fasteners 10f are also provided on the edge of the front opening of the main body part 10 so that they can be engaged and disengaged with each other.

[0031] Furthermore, a portion without a slide fastener is provided at the center of the upper edge of the front portion 20, and this portion serves as a grip portion 25, which can be gripped to open the slide fasteners 10f, 20f.

[0032] The grip portion 25 may be provided within a range that can be grasped by the user's hand, and by grasping the grip portion 25 and pulling it forward and / or downward, the front portion 20 is detached from the main body portion 10, and the front portion of the cover is opened. That is, it is a structure for rescuing a child inside in an emergency. When a child gets on or off the car seat, one of the left and right sides of the zipper 20f can be opened.

[0033] The transparent portion of the front part 20 is made of a transparent PVC material. The central lower edge 20s of this front portion 20 wraps around to the underside of the footrest of the seat, and the lower edge portions 20r of the side portions on both sides wrap around to the undersides of both sides of the footrest of the seat and are attached by converging. This is because a converging member such as an elastic cord is sewn into the lower edge of the front portion 20 as appropriate.

[0034] When engaging the front portion 20 with the main body portion 10, the sliders located at the lower ends of both side edges of the front portion 20 are engaged with the respective starting ends of the slide fasteners 10f at the lower ends of both sides of the front main body portion 10, and the two can be engaged by pulling the sliders upward.

[0035] However, the engagement between the two sliders stops at the position of the gripping portion 25 located at the center of the upper end of the front portion 20. Therefore, the gripping portion 25 remains unengaged as a hole. By inserting a hand into the hole of the grip portion 25, the front portion 20 can be released from the main body portion 10.

[0036] FIG. 2 is an explanatory view showing a state in which a child seat cover according to another embodiment of the present invention is attached to a rear child seat and the grip portion at the front part is gripped and opened downward to an almost fully open state.

[0037] The cover 2 according to this embodiment is attached to cover a rear child seat fixed to the rear carrier of a bicycle. The basic structure of this rear child car seat is the same as that of the front child car seat, but the position of the foot rest is different. That is, in this rear child seat, the foot rests are located on both sides in front of the seat bottom, i.e., on both sides of the rear wheel of the bicycle.

[0038] In the cover 2 of this embodiment, the main body 10 has the same shape as the upper covering portion of the main body 10 of the front child seat cover described above, and can cover the upper part of the seat hood, headrest, and backrest, and has a circular linear member arranged along its lower peripheral edge. A slide fastener 10f is provided along the entire edge of the lower opening of the main body 10.

[0039] On the other hand, the front portion 20 is engaged along the edge of the lower opening of the main body portion 10 as described above, and therefore can cover the front portion, both side portions and the rear portion of the backrest of the seat. That is, the front covering portion of the front portion 20 covers the front portion of the seat, its side covering portions cover the side portions of the seat, and its back covering portion covers the back side (lower portion) of the backrest portion of the seat.

[0040] Here, similarly to the front child seat cover according to the above embodiment, a grip portion 25 is provided at the center of the upper end of the front portion 20, that is, approximately at the center of the upper edge. The grip portion 25 is a portion where the slide fastener 20f is not provided, and is provided with a width just large enough for the user's hand to fit through.

[0041] This grip portion 25 is reinforced by sewing on a strip of fabric as a reinforcing member, and is similar to the front child seat cover in that it is formed so that the upper edge of the front portion 20 can be easily grasped by hand.

[0042] Also, like the above-mentioned front child seat cover, this rear child seat cover also has a sunshade canopy portion 30 extending from the front to both sides of the annular linear member arranged on the lower edge of the main body portion 10. The eaves portion 30 is formed by disposing another linear member in front of the annular linear member and stretching a fabric between these two linear members.

[0043] In the above-mentioned front part 20, its upper part and the part from the central part to the front (lower part) are formed from a transparent PVC material, and a linear member as a bone member 23 is arranged laterally in the central part to give the front main body part 20 shape retention.

[0044] A cutout 26 is provided in the center of the lower end of the front part 20, and this cutout 26 is provided to remove the front support part of the bicycle carrier, and the parts on both sides of it become foot rest covering parts 27, 27 that cover the foot rest part of the seat.

[0045] Furthermore, when the front portion 20 is engaged with the main body portion 10 by slide fasteners 10f and 20f and attached to the rear seat, the rear side edges of both sides of the lower part of the front portion 20 are attached by wrapping around to the back side of the backrest portion of the seat.

[0046] The engagement between the front portion 20 and the main body portion 10 by the slide fastener is the same as in the front child seat cover, but the slide fasteners 20f located on both sides of the front portion 20, and the sliders located at both lower ends which are the starting points of the 20f, can be engaged with both starting points of the slide fasteners 10f of the main body portion 10 (both starting points located approximately in the center of the rear of the main body portion 10) and slid diagonally upward toward the front to engage.

[0047] Then, the slider stops at the gripping portion 25, and a hole is formed at the gripping portion 25. The front part 20 can be easily released from the main body part 10 by inserting a hand into this hole. When a child gets in or out of the car seat, either the left or right slide fastener 10f or 20f can be opened, just like the front child seat cover.

[0048] Figure 3 is an enlarged conceptual explanatory diagram showing the edge of the front part of the cover according to the present invention, in which (A) shows the state in which the waterproof tape and the zipper base are overlapped on the edge of the front part of the cover, (B) shows the state in which the edge in the joined and sewn state shown in the previous figure (A) is covered with a edging fabric and sewn, (C) shows the state in which the slide zipper base is turned over from the state in the previous figure (B) to the back side in the figure and sewn, and (D) shows a cross section of the previous figure (C).

[0049] FIG. 3 shows the characteristic features of the present invention. The structure of the edge of the front portion 20 of the cover is a characteristic feature of the present invention, and since the structure will be more clearly understood by showing the sewing process, the sewing process will be described below.

[0050] First, the front portion 20 is made of a transparent synthetic resin material, in this case PVC material, as described above, and the waterproof tape 3 is laid over the edge 20e of the front portion 20 so that the right edge in the figure is aligned. The figure shows the state before they are superimposed. In addition, in the figure, in order to clearly show the structure of the edge portion 20e of the front portion 20, the upper edge portion of the front portion 20 is shown cut away, but in reality it continues upward and connects to the grip portion.

[0051] The waterproof tape 3 consists of a long, narrow polyester tape (approximately 20 mm wide) with a polyurethane (PU) coating adhered to one side, in this case the front portion 20 side, and can be formed by heat welding to the edge of the front portion 20. This polyurethane layer provides a water-stopping or waterproof effect. Furthermore, the waterproof tape 3 uses polyester fabric, which has made it possible to improve the tear strength of the edge of the front portion 20 to approximately three times that of conventional products.

[0052] On the other hand, the base 20k of the slide fastener 20f also has a width of about 20 mm, with the teeth located on the left side in the figure, and the right edge of the base 20k is aligned with the right edge of the front part 20 and sewn together.

[0053] Thereafter, as shown in FIG. 3(B), the edges of the front portion 20 and the slide fastener base 20k are covered with a edging fabric 5 having a width of about 20 mm and sewn together. Incidentally, since illustrating the sewn state makes it difficult to understand the state of the joining fabric or base, the sewing threads are omitted from the illustration, and each component is shown with a small gap between them.

[0054] 3(C) shows the state in which the slide fastener 20f has been folded (flipped) from the left side to the right side in the state shown in FIG. 3(B) and sewn in parallel along the slide fastener 20f. Again, for ease of understanding, the sewing thread is omitted from the illustration, and the components are shown with spaces between them.

[0055] FIG. 3(D) is a cross-sectional view of the edge of the front portion 20 of FIG. 3(C), and the positional relationship of each component is clear. As can be seen from these figures, the edging fabric 5 covers the edge of the front part 20 where the slide fastener base 20k and the waterproof tape 3 are adhered, and in this cross-sectional view, the front part 20 is folded back to the side opposite the slide fastener 20f and the entire edge is sewn together, for example at the position shown by the dotted line, to complete the edge of the front part 20.

[0056] As can be seen from the above explanation, the sewing or sewing is performed by three stitches, namely, the first sewing step in which the slide fastener base 20k and the edge of the front portion 20 are sewn together in Figure (A), the second sewing step in which the edge is covered with the edging fabric 5 in Figure (B) and sewn or sewn together, and the third sewing step in which the teeth of the slide fastener 20f are inverted and then sewn together in Figure (C), to complete the sewing of the edge of the front portion 20.

[0057] The present invention is characterized by the fact that this type of sewing, in particular by adhering the water-stop tape 3 along the edge of the front part 20 and sewing the slide fastener base and the edging fabric together, improves the strength and water-stopping and waterproofing effects.

[0058] Although the embodiment of the present invention has been described above, various design modifications are possible in the present invention as described below. First, in the present invention, the characteristic feature is the edge structure of the front part of the cover, so the structure and shape of the cover other than this edge structure can be freely changed in design. In other words, the child seat cover is a bicycle child seat cover that is fixed to the handlebars or rear cargo area of ​​a bicycle and can cover almost the entire headrest and / or hooded child seat, and has a slide fastener along the periphery of the front part, which is made of a transparent synthetic resin sheet, and a gripping part without a slide fastener at the center of the upper edge of the periphery of the front part, and by gripping the gripping part and pulling it forward and / or downward, the slide fastener is released and the front part is opened, and other configurations can be designed freely.

[0059] The size and shape of the entire cover can also be changed appropriately to suit the shape of the seat. The material can also be changed as appropriate depending on the part of the cover.

[0060] It is also possible to provide a belt-like member or a circular belt member on the inner surface of the main body so that the belt-like member or the circular belt member can be attached to the headrest of the seat. This belt-shaped member may be a type in which a pair of belt members with fastening devices at the ends can be connected to each other, or it may be a stretchable circular belt sewn to the inside of the back of the seat. This can be provided as a precaution to prevent the main body of the cover from falling off the seat.

[0061] Slide fasteners that engage with slide fasteners provided on the peripheral edge of the lower opening or front opening of the main body are provided on the upper edge and both side edges of the front part, but the slider that engages the two can be provided on either the side of the main body or the side of the front part. Then, both ends (starting ends) of the slide fastener in the front part engage with both ends (both starting ends) of the slide fastener in the main body part, and the slider is pulled upward to engage, and then engages up to the gripping part, which is the non-engaging part in the center of the upper end, thereby forming a hole in the gripping part.

[0062] It is also possible to form a threaded portion at the lower edge of the front part and place an elastic string-like member inside it, or to provide a belt member at the lower end of the center of the front of this lower part so that it can be fixed to the saddle post or other frame of a bicycle.

[0063] The width and other dimensions of the waterproof tape can be changed as needed. The material can also be freely changed as needed. The size and material of the edging fabric can also be freely selected. The size or number of the slide fastener can also be freely set. Of course, the shape of the front portion can also be modified as needed.

[0064] As described above, the present invention provides a child seat cover whose front portion can be released in one go from its main body, and which has a slide fastener base formed by adhering a tape-like fabric such as a waterproof tape to the edge of the front portion, thereby improving the strength and waterproofness of this edge.
