[0020] A ninth aspect of the present invention is a bicycle child seat cover attachment aid according to the eighth invention, characterized in that it is provided with a pressing member that can maintain the standing portion and the abutment portion in the folded state. Effect of the Invention

[0021] The first aspect of the present invention is an attachment aid used when attaching a cover to a seat fixed to a bicycle, the front part of the main body of this attachment aid can be arranged on the rear side of the seat, an attachment member is provided on the rear part, and attachment means for attaching the attachment aid to the seat is provided at an appropriate position on the main body, so that the main body can be attached to the rear side of the seat and the attachment member on the rear part of the main body can be engaged with an attachment member provided on the inside of the rear part of the cover, thereby attaching the cover at an appropriate height position.

[0022] In other words, the main body of this mounting aid can be attached to the rear side of various types of seats, and the fastening member provided on the rear part can be mutually engaged with the fastening member provided on the inside of the rear part of the cover, so that the height position of the cover can be freely maintained at any appropriate height when mounting.

[0023] As a result, by engaging the back part of the cover with the main body of the mounting aid in accordance with the sitting height of the child sitting on the seat, the height position of the top part of the cover can be appropriately set and changed, and the top of the child's head will not come into contact with the top part of the cover in the internal space of the cover, or even if it does come into contact, the weight of the cover will not be directly placed on the child's head, improving the living environment.

[0024] Furthermore, the mounting aid of the present invention is designed to be mounted on seats that do not have a headrest. Although this type of seat does not have a headrest, the seat has a pair of holes for attaching a seat belt at an appropriate height from the upper edge of the back surface, and in the present invention, these two holes can be utilized to insert the tip of the upper belt member through these holes and wrap it around it to mount the device. Of course, even if the headrest is integrally formed with the back portion of the seat, the back portion having the headrest shape can be attached by wrapping it around the lower edge of the headrest shape without using the above-mentioned hole portion.

[0025] On the other hand, the lower belt member is provided at the lower portion of the main body of the mounting aid, and this lower belt member can be hung over the handle post or the frame of the carrier of the bicycle and mounted. That is, in the present invention, the mounting aid can be mounted on the rear side of the rear surface of the seat at at least three points on the upper belt member and the lower belt member.

[0026] In seats of the type in which the headrest is integrated but does not have the headrest shape, the pair of holes on the back surface are holes for attaching a seat belt, and since two (a pair) are provided horizontally at a suitable distance from the upper edge of the slightly upper part of the back surface, the fastening force of the pair of upper belt members alone is weak, and the lower part of the main body of the fastening aid is not fixed, that is, the lower part of the main body flaps back and forth. At least one lower belt member is provided in order to prevent this flapping and to securely attach the mounting aid to the rear side of the rear part of the seat.

[0027] As described above, the mounting aid of the present invention is firmly attached and fixed to the rear side of the rear portion of the seat at at least three points by a pair of upper belt members and at least one lower belt member. Thereafter, the fastening member provided on the rear part of the main body of the mounting aid and the fastening member provided on the inside of the rear part of the cover can be engaged with each other, thereby allowing the cover to be attached at an appropriate height position.

[0028] In the second aspect of the present invention, the configurations of the upper belt member and the main body are more specifically embodied. In other words, each of the upper belt members has a fastening device provided on one end of the belt member, the side with the fastening device is fixed to the back portion of the main body of the wearing aid, and the other end, which is the tip portion, is arranged so that it can be wrapped around from the upper edge of the main body to the front portion, and a pair of insertion holes are provided on the main body side at approximately the same distance from the upper edge, so that the main body of the wearing aid is arranged on the back side of the child seat and the tip portion of the upper belt member can be inserted into the hole provided in the back portion of the child seat from the front side, or wrapped around the lower edge of the headrest of the child seat from the front side, and then inserted into the insertion hole in the main body of the wearing aid and pulled out to the back side, and its tip portion can be engaged with the fastening device, and the wearing aid can be attached to the back side of the seat.

[0029] In the third aspect of the present invention, the configuration of the above-mentioned lower belt member is embodied; that is, the lower belt member is provided with connecting devices on both end sides of the belt member that can be connected to each other, and the lower belt member is hung over the handle post or the frame of the luggage rack of the bicycle to connect the connecting devices together, and then one end of the belt member can be pulled and tensioned.

[0030] In the fourth aspect of the present invention, it is specified that the upper belt member and / or the lower belt member is made of an elastic belt-like member, and it is characterized in that the belt members can be stretched in a more taut state.

[0031] In the fifth aspect of the present invention, another embodiment of the upper belt member is specified. In other words, the upper belt member consists of a pair of stretchable belt-shaped members arranged vertically on the front part of the main body of the mounting aid, and an attachment portion is provided at the tip of the belt-shaped member, which can be wrapped around the upper edge of the child seat and inserted into the hole of the child seat from the front side and wrapped around the back side, or wrapped around the upper edge of the child seat and the lower edge of the headrest below it, and the attachment portion of the tip of the belt-shaped member can be attached to the attachment portion provided on the front part of the main body of the mounting aid, thereby allowing the mounting aid to be mounted on the seat. In this case, it is possible to implement the present invention without providing a pair of insertion holes on the main body of the putting aid as in the second invention described above.

[0032] In the sixth aspect of the present invention, the fastening member provided on the rear part of the main body of the above-mentioned wearing aid is specified, that is, the fastening member provided on the rear part of the main body consists of a hook-and-loop fastener, and this hook-and-loop fastener is provided in two vertical band-like rows, approximately parallel to each other, on the rear part of the main body of the above-mentioned wearing aid. By arranging the fastening members vertically, i.e., in a band shape in the up-down direction, the engagement with the fastening members provided on the inside of the rear part of the cover can be freely changed up and down, and the height of the top part of the cover can be freely adjusted up and down.

[0033] In the seventh aspect of the present invention, there is a seat having a back portion with a different shape from the above-mentioned child seat, in which the upper part of the back portion has a bulge that bulges toward the back side, and this seat is designed to be compatible with this type of seat. The bulge at the upper part of the back surface is formed to fit the shape of the head of a seated child, and a headrest is integrated into the upper part of the back surface.

[0034] In a seat having a bulge like this, when the main body part according to the first to sixth inventions is attached, a gap is created between the lower part and the back surface of the seat, resulting in the problem that the main body part cannot be securely positioned on the back surface of the seat. Therefore, in the seventh aspect of the invention, an undulating member is provided on the front surface of the main body.

[0035] By positioning this undulating member below the bulging portion of the seat, the gap between the seat back and the undulating member is eliminated, allowing the main body to be securely disposed on the seat back.

[0036] In the eighth invention of the present invention, the undulating member is more specifically defined in the seventh invention above, that is, the undulating member is band-shaped, both ends of which are provided with fixing parts for fixing to the main body, and the undulating part is located halfway between these fixing parts, and this undulating part is composed of standing parts at both ends and abutting parts located halfway between the standing parts, and these abutting parts and the standing parts at both ends are formed to be freely foldable. As a result, if necessary, i.e. in a type having a bulge in the upper part of the back surface of the seat, the main body can be firmly positioned and attached to the back surface of the seat by raising the undulating portion and abutting the abutment portion below the bulge in the back surface of the seat.

[0037] The ninth aspect of the present invention is characterized in that a pressing member is provided that can maintain the standing portion and the abutment portion in a folded state, and when used in a seat that does not have a bulge portion on the back surface, it is possible to fold the standing portion in this manner and maintain it in the folded state by the pressing member for use.

The bottom surface of this child seat cover 30 is open, but a stretchable convergence string 36 is inserted through the entire or part of the periphery of this bottom surface so that the opening of the bottom surface can be converged.

[0067] The fastening members 40, 40 are provided on the inside of the rear portion 33 of the child seat cover 30. In this embodiment, these fastening members 40 are provided by sewing a hook-and-loop fastener to one surface of a belt-shaped member.

[0068] As shown in the figure, the fastening members 40 are arranged in a vertical strip shape on both sides of the rear portion 33 of the cover 30, and are formed so as to be capable of engaging with the fastening members 20, 20 arranged on the rear portion of the main body portion 11 of the above-mentioned mounting aid 10.

[0069] In other words, the attachment member 20 provided on the back portion of the main body 11 of the above-mentioned mounting aid 10 and the attachment member 40 of the cover 30 are attached to each other at that height position while appropriately ensuring the height of the top of the cover, thereby making it possible to maintain the height of the top of the cover 30 at the desired height position.

[0070] This allows the attachment position of the two to be adjusted up or down depending on the sitting height of the child seated in the seat, preventing the top of the cover from coming into contact with the top of the child's head, and making it possible to freely change the height position of the top of the cover in the interior space.

[0071] FIG. 7 is an explanatory view of the front side of the second embodiment of the putting aid of the present invention. In the putting aid 1 according to the second embodiment, an undulating member 2 is provided on the front surface of the putting aid 10 according to the first embodiment. The other configurations are the same as those of the putting aid 10 of the first embodiment.

[0072] That is, as shown in FIG. 7, the main body 11 of the wearing aid 1 according to the present invention has a substantially pentagonal shape similar to the shape of a baseball home base when viewed from the front. The main body 11 is formed in a plate shape and has flexibility.

[0073] The inside of the main body 11 may be provided with a core material made of synthetic resin. The core material can be, for example, bee pollen, but it may also be a thick sheet of cloth. Alternatively, the main body 11 may be formed by combining strip-shaped members lengthwise and widthwise and knitting them into a single sheet-like member, and there is no problem even if gaps are provided during the knitting. In short, any sheet-like or net-like object that can be appropriately placed on the rear side of the rear part of the child seat may be used.

[0074] At the upper portion of the main body 11, a pair (two pieces) of upper belt members 12, 12 are provided on the left and right sides. These upper belt members 12, 12 are provided in pairs side by side in the lateral direction at a position on the back surface of the main body 11 at the same distance downward from the upper edge 11j of the main body 11 (see FIG. 1).

[0075] The upper belt member 12 has the same configuration on the left and right sides, and is provided with a fastener 13 at one end (the base end 12b at the lower end in the figure), and this base end 12b is fixed to the back portion of the main body 11 (see Figure 1). The other end of the upper belt member 12, that is, a tip end 12t, is a free end, and is wound around the back surface of the child seat (see FIG. 4). Further, the upper belt members 12 are each provided with an insertion hole 16 at a portion slightly below the fastening members 13.

[0076] The fastener 13 provided at the base end 12b of the upper belt member 12 has a shape in which two horizontal bars are hung across a substantially rectangular frame, and is what is called an "adjuster buckle." The base end 12b of the belt member 12 is fixed to the upper horizontal bar, and as will be explained later, the tip end 12t is wrapped around the back surface of the child seat and pulled out toward the back surface of the main body 11 through the insertion hole 16, and the tip end 12t is inserted from bottom to top into the upper hole of the lower horizontal bar of the fastener 13, and then inserted from top to bottom through the lower hole of the horizontal bar to pull it below the fastener 13, and then pulled downward to tighten it, thereby fixing it (see Figure 4).

[0077] A lower belt member 14 is provided on the lower portion of the main body portion 11. The lower belt member 14 is inserted into a hole 17 formed in the lower portion of the main body 11, and is a single belt member disposed in a circular shape.

[0078] A length adjustment frame 18 is provided at one end of the lower belt member 14 which is made up of a single belt member (see FIG. 1). This length adjustment frame 18 is a generally rectangular frame with one horizontal bar provided in the center, and is what is called an "adjuster buckle." One end of the lower belt member 14 is fixed to the central horizontal bar of the length adjustment member 18, and is looped around, and the other end 14t is inserted through the upper and lower frames of the length adjustment member 18 again.

[0079] As a result, one end of the lower belt member 14 is formed into a loop shape, and one connector 15a is provided at the middle portion thereof. As described above, the other end 14t of the lower belt member 14 is inserted through the length adjustment frame 18, through the insertion hole 17 provided in the lower part of the main body 11, and then through the other connecting device 15b provided on the other end side.

[0080] With the above-mentioned configuration, the lower belt member 14 is formed into a closed loop shape by connecting the two connecting members 15a, 15b to each other. This lower belt member 14 is arranged so as to be hung around the handle post or the frame of the luggage rack of the bicycle, and then the other end 14t of the lower belt member 14 can be tensioned by pulling it tight, i.e., by pulling it tight through the insertion portion of the connecting device 15b (see Figure 4).

[0081] A pair of fastening members 20, 20 are provided on both the left and right sides of the rear surface side of the main body 11 (see FIG. 1). The fastening member 20 is a belt-shaped member sewn to both sides of the back surface of the main body 11, and a hook-and-loop fastener is provided on the back surface. The hook-and-loop fasteners 20, 20 can be mutually fastened to a hook-and-loop fastener (fastening member) provided on the inside of the rear surface of the child seat cover.

[0082] As described above, in the second embodiment, the configuration other than the undulating member 2 is exactly the same as in the first embodiment. The only different configuration is the relief member 2 described above.

[0083] This undulating member 2 is applied to a child seat on which the mounting aid 1 is mounted, the rear portion of which bulges out towards the rear side, as will be explained later in FIG. The bulge on the back of the seat is provided to prevent the back of a seated child's head from coming into contact with the back of the seat and causing the face to turn downward, and to act as a head support (headrest) to adequately protect the child's head.

[0084] When the mounting aid 10 of the first embodiment of the present invention is mounted on a seat having a bulge on the back surface of the seat in this manner, a gap is created on the front side of the main body 11, causing the lower part of the main body 11 to flap around. In order to eliminate this fluttering, the second embodiment was devised.

[0085] That is, the undulating member 2 is provided on the front part of the main body 11 corresponding to the lower part of the bulging part of the sheet. The undulating member 2 is a belt-like member, and is made of a double-bag-like member that can accommodate a core material inside (although it is of course possible to use a member other than a belt-like member). Fixed parts 3, 3 are provided on both ends, and the undulating part is located between these fixed parts 3, 3.

[0086] Standing portions 4, 4 are provided on both ends of this undulating portion, and a contact portion 5 is provided between these standing portions 4, 4. The inside of the upright portions 4, 4 and the abutment portion 5 each have a thin synthetic resin plate as a core material, and the outside is covered with synthetic fiber fabric so that they can be folded at the boundary between them.

[0087] The fixing parts 3, 3 at both ends are sewn and fixed to the main body part 11. The fixing parts 3, 3 have one lower part (left side in the figure) sewn to the outside, and the other upper part (right side) sewn to the main body part 11 inside the standing part 4.

[0088] This sewing method is completely free, and it is also possible to sew the fixing part 3 on the left side of the drawing to the inside of the standing part and the fixing part 3 on the right side of the drawing to the outside of the standing part 4. Alternatively, it is also possible to arrange both fixing parts 3 on the outside of the standing part 4, or both fixing parts 3 on the inside of the standing part 4. Reference numeral 6 in the figure indicates a belt-like pressing member which, when the undulating portion is folded, holds the undulating portion in the folded state, as will be explained in the next figure.

[0089] As described above, in this second embodiment, the undulating member 2 is provided in approximately the center of the front side of the main body 11, at a position corresponding to the underside of the bulge on the back of the child seat, and is fixed to the front of the main body 11 by the fixing parts 3, 3 at both ends. By raising the upright parts 4, 4 of the undulating part between the fixing parts 3, 3, the central abutment part 5 is maintained at a predetermined height, and it acts like a spacer that fills the gap between the front of the main body 11 and the back of the seat, so that when it is disposed on the back of the seat and attached, the lower part of the main body 11 does not flap around.

[0090] FIG. 8 is an explanatory diagram illustrating the state in which the undulating member shown in FIG. 7 is folded. From this figure, the folded state of the undulating member 2 provided on the front part of the wearing aid 1 according to the second embodiment of the present invention can be clearly seen.

[0091] By folding the upper standing portion 4 in FIG. 7 downward, the abutting portion 5 is folded inward, and the lower standing portion 3 is folded on top of it, so that the standing portion 4, the abutting portion 5, and the standing portion 4 are folded so as to overlap each other.

[0092] Thereafter, in order to maintain this folded state, a belt-like pressing member 6 with both ends free can be wrapped around the folded state and the free ends of both ends can be fastened and fixed to each other with a hook-and-loop fastener.

[0093] In other words, the pressing member 6 is belt-shaped with its approximate center sewn to the main body 11 and both ends being free ends, and both ends are provided with hook-and-loop fasteners that can be attached to each other, so that the folded upright portion and the abutting portion can be maintained in the folded state. Of course, the hook-and-loop fasteners at both ends can also be connected and fixed by providing a connecting buckle at one end of the pressing member 6 made of a belt.

[0094] As a result, the mounting aid of the second embodiment, like that of the first embodiment, can also be used with child seats that do not have a bulge on the back surface.

[0095] FIG. 9 is an explanatory side view showing a state in which the mounting aid according to the second embodiment is mounted on a child seat. From this figure, an example of use of the wearing aid according to the second embodiment of the present invention can be seen.

[0096] In the child seat S shown in this figure, the back portion H is not flat like the child seat H shown in FIG. 3, but is of a type that is provided with a bulging portion Hb that bulges out on the back side. As already mentioned, this bulge Hb is provided so as to properly fit the back of the head of a seated infant.

[0097] Due to the bulge Hb, a gap is created between the front side of the main body 11 of the putting aid 1 and the rear surface H of the seat. The undulating member 2 was invented as a spacer to fill this gap.

[0098] In this figure, the pressing member is omitted from the illustration, and the upper belt member on the far side (the rear side of the drawing) is hidden by the undulating member and cannot be seen. As shown in the figure, by raising the standing portions 4, 4, the intermediate abutment portion 5 comes into contact with the back portion of the back portion H of the seat, and the lower end portion of the main body portion 11 is pulled downward by the tension of the lower belt member 14, so that it is firmly abutted against the back portion H of the seat S and attached thereto. This prevents the lower portion of the main body 11 from flapping about.

[0099] Thereafter, the child seat cover can be attached at an appropriate height by engaging the fastening member (hook-and-loop fastener) provided on the rear portion of the main body 11 with the fastening member (hook-and-loop fastener) provided on the inside of the rear portion of the child seat cover. The method for attaching this cover is exactly the same as that for the attachment aid of the first embodiment.

[0100] The second embodiment has been described above, and its characteristic feature is the undulating member, while the other configurations are the same as those of the first embodiment. The undulating member 2 is provided in a strip shape on the front surface of the main body 11 in the vertical direction.

[0101] However, the relief members 2 can also be provided laterally. In other words, it is easily possible to provide the fixing parts 3, 3 at both ends in the horizontal direction. In short, there only needs to be an undulating portion between the fixed portions at both ends, and the orientation of the undulating portion is completely free. In addition, although this undulating portion is formed in a strip shape, it is not necessarily strip-shaped, i.e., its width does not have to be constant, and the width and rising height can be freely designed and changed, and its size and shape can be freely designed.

[0102] For example, the standing portion may be formed into a trapezoidal shape by making the width of the base end side (main body side) larger and the width of the abutment side smaller. Similarly, the shape of the fixing portion may be formed into a trapezoidal shape with a smaller width on the upright side and a larger width on the opposite end.

[0103] Furthermore, the positions of the fixing parts 3, 3 can be freely set either on the outside or inside of the standing part. When the standing member 2 is provided in the horizontal direction as described above, the pressing member is provided in the vertical direction.

[0104] In the second embodiment, like the first embodiment, the upper belt member can be either inserted through a hole in the back surface of the seat or wrapped around the lower edge of the headrest.

[0105] Although two examples of the embodiment of the present invention have been described above, the present invention can be modified in various ways as described below.

[0106] In the above-described first embodiment, the child seat to be installed did not have a headrest shape at the upper part of the back surface, as shown in FIG. 3, so the tip of the upper belt member was installed by inserting it through a pair of holes provided in the upper part of the back surface of the seat.

[0107] On the other hand, some seats have a headrest shape at the upper part of their back portion, and this type of seat can be attached by wrapping an upper belt member around the upper edge to the lower edge of the headrest at the upper part of the back portion. Therefore, when the upper belt member is wound around the latter type of sheet, the pair of holes provided on the back surface of the sheet does not need to be used.

[0108] In both the first and second embodiments described above, one end of the upper belt member, on which the fastening device is provided, is fixed to the rear side of the main body portion, but this one end may also be fixed to the front side of the main body portion. When fixing to the front surface side of the main body, it is preferable to use a hook-and-loop fastener (fastening portion) as the fastener specified in the first and second embodiments.

[0109] In other words, the upper belt member is formed from a stretchable belt-shaped member arranged vertically on the front portion of the main body, with an attachment portion provided at the tip of this belt-shaped member, and the tip of this belt-shaped member can be wrapped around the upper edge of the child seat and inserted into the hole in the child seat from the front side and wrapped around the back side, or wrapped around the upper edge of the child seat and around the lower edge of the headrest below it, and the attachment portion of the tip of the belt-shaped member can be attached by engaging it with the attachment portion provided on the front portion of the main body.

[0110] For example, a hook-and-loop fastener (attachment portion) is provided on the front side of the base end of the upper belt member, and another hook-and-loop fastener (attachment portion) that can be engaged with the hook-and-loop fastener is provided at the other tip end, and the tip end of this upper belt member is inserted into the hole in the sheet from the front side to the rear side, and then the hook-and-loop fastener at the tip end is engaged with the hook-and-loop fastener on the base end side, allowing the attachment aid to be attached using the hole in the sheet with the upper belt member.

[0111] In this case, it is highly preferable to utilize an elastic belt member as the upper belt member. This is because the hook-and-loop fasteners on both ends of the belt member are located between the main body of the mounting aid and the back of the seat, and in order to attach the hook-and-loop fasteners to each other, it is necessary to separate the main body from the seat.

[0112] The mounting aid according to the present invention can be attached to any child seat that is fixed to the handlebars or rear carrier of a bicycle, and a cover can be attached to the child seat. When mounting to a front child seat, the lower belt member can be mounted by hanging over or wrapping around the handlebar post of the bicycle.

[0113] The cover to be attached to the bicycle seat can be of any type, and as long as it is a cover that can cover almost the entire seat and has an attachment member on the inside of the back part, various types of covers can be attached at an appropriate height. The cover may be a one-piece type, a two-piece type consisting of an upper and lower part, or the cover may have various frameworks arranged thereon.

[0114] The main body of the mounting aid according to the present invention is plate- or sheet-shaped, and so long as it can be placed on the back side of the seat, its external shape and structure can be designed and modified completely freely.

[0115] For example, the outer shape may be a substantially pentagonal shape as in the above embodiment, a substantially rectangular shape, a substantially oval shape, or a polygonal shape. The structure may be such that the interior is lined with cushioning material or a flexible synthetic resin plate material and the exterior is covered with fabric or sheet material made of another material, or it may be a single elastic or flexible plate-like object.

[0116] Furthermore, the main body of the wearing aid may be a belt woven vertically and horizontally, and the weaving may have gaps, i.e., holes or windows. In short, as long as it can be disposed on the back surface of the seat, its structure is completely open to choice.

[0117] In the upper belt member, the fastener used in the above embodiment is a generally rectangular frame with two horizontal bars, known as an adjuster buckle, but this fastener may be a hook-and-loop fastener that can be fastened to each other, or a connector consisting of male and female one-touch buckles used in the lower belt member may be used, but considering the size of the hole in the seat, the fastener in the above embodiment is most preferable. This is because there is nothing at the tip of the belt member, making it easy to insert it into the hole.

[0118] The upper belt member and the lower belt member can also be appropriately modified in design, and may be not only a simple band-like belt as in the above embodiment, but also a stretchable rubber band or the like. Furthermore, at least one lower belt member is sufficient, but two or more are also free to be provided. The main body can be attached to the seat at three points, including the pair of upper belt members and the lower belt member.

[0119] In the above embodiment, the fastening members (hook-and-loop fasteners) provided on the back portion of the main body of the wearing aid are provided in pairs vertically on both sides of the back portion, but these fastening members may also be provided horizontally, or a single band-like member may be provided horizontally, or multiple members may be provided approximately parallel to each other. Of course, the fastening member may be provided over the entire rear surface of the main body.

[0120] This allows the height position of the cover to be appropriately determined by engaging with the fastening member (hook-and-loop fastener) provided on the inside of the back surface of the cover, and the cover can be attached to the seat at an appropriate height position.

[0121] As described above, the present invention is an attachment aid used when attaching a child seat cover that can be used to cover the front or rear child seat of a bicycle to said seat, and this attachment aid is attached to the back side of the seat and the cover can be attached to the seat by engaging an attachment member provided on the back part of the attachment aid with an attachment member provided on the inside of the back part of the cover, thereby allowing the cover to be attached at an appropriate height position and providing space for the top of the head of a child seated inside the cover so that the child seat cover can be attached to the seat.
