Summary of the Invention

[0007] The above-mentioned child seat cover is waterproof, ensuring that infants in the child seat stay dry even in the rain.

[0008] However, the inventor of this invention faced a problem in that if it rains continuously while the bicycle is parked, water can seep into the child seat cover even if a child seat cover is attached, causing the seat surface of the child seat to get wet.

[0009] Upon investigating the cause of water seeping into the cover, it was discovered that rainwater was accumulating in the canvas portion located above the child seat, which was the main component of the child seat cover, causing water to seep inside the cover.

[0010] In other words, the canopy positioned above the child seat is supported by a pair of front and rear canopy frames that are relatively rotatable, so there is almost no tension on it. As a result, it can wrinkle downwards or sag under its own weight, and if it continues to rain in this state, the rainwater does not flow off the canopy to the sides but tends to accumulate on top of it. Once rainwater accumulates on the canopy, the weight of the water causes the canopy to sag more and more, and an even larger amount of rainwater accumulates on top of it. In this case, it has been found that some of the large amount of rainwater accumulated on the canopy gradually seeps into the inside of the cover through the seams of the canopy, resulting in problems such as the child seat surface getting wet.

[0011] The problem this invention aims to solve is to provide a child seat cover that prevents rainwater from easily seeping inside, even when it rains continuously while the bicycle is parked. [Means for solving the problem]

[0012] The inventor of this invention considered how to prevent rainwater from accumulating on the canopy located above the child seat. As a result of this consideration, the inventor came up with the idea that by adding a core material that spans between the front and rear canopy frames to prevent the central part of the canopy from sagging downwards in the left-right direction, it would be possible to allow rainwater to flow off the canopy to the left and right when it rains continuously while the bicycle is parked.

[0013] Based on this idea, this invention provides a child seat cover with the following configuration to solve the above-mentioned problems. [Configuration 1] It has a shape in which the front-to-back dimension is largest in the center of the left-to-right direction and gradually decreases towards both sides, and is a canvas that is positioned above the child seat of a bicycle, A front frame of the canvas is provided that extends in the left-right direction along the front edge of the canvas and supports the front edge of the canvas, It has a rear canopy frame that extends in the left-right direction along the rear edge of the canopy and supports the rear edge of the canopy, In a bicycle child seat cover in which at least one of the front and rear canopy frames is rotatable in the front-rear direction with its left and right ends as pivot points, A bicycle child seat cover characterized in that a central bridging core is detachably attached to the left-right central portion of the canvas fabric, spanning in the front-to-back direction between the left-to-right central portion of the front canvas frame and the left-to-right central portion of the rear canvas frame, and the left-to-right central portion of the canvas fabric is supported by the central bridging core to prevent it from sagging downward.

[0014] With this configuration, the central portion of the canvas fabric in the left-right direction is supported by a central bridging core positioned to span between the central portions of the front and rear canvas frames. This prevents the central portion of the canvas fabric from sagging downwards, maintaining a straight, ridge-like shape. In other words, the central bridging core creates a slope in the canvas fabric that slopes downwards from the center outwards to both sides. Therefore, when it rains continuously while the bicycle is parked, the rainwater can flow smoothly off the canvas fabric to the left and right, preventing water from accumulating on the fabric and seeping into the cover.

[0015] Furthermore, since the central connecting core is detachable, the canopy can be folded compactly by removing the central connecting core before attaching the child seat cover to the child seat (for example, at the shipping stage).

[0016] [Configuration 2] A bicycle child seat cover according to Configuration 1, wherein the central portion of the canvas fabric in the left-right direction is provided with a core material pocket that extends elongated in the front-to-back direction, a core material insertion opening for inserting the central bridging core material into the core material pocket, and a protrusion prevention piece that covers the core material insertion opening to prevent the end of the central bridging core material from protruding out of the core material insertion opening.

[0017] With this configuration, the central cross-bracing core material can be attached to the canvas by inserting it into the core material pocket through the core material insertion opening.

[0018] Furthermore, since the core material insertion opening is covered with a protrusion prevention piece, even if an unexpected external force or impact is applied to the front or rear canopy frame, it is possible to reliably prevent the end of the central connecting core material from popping out of the core material insertion opening.

[0019] [Configuration 3] The core material pocket is formed by sewing a strip of fabric to the central part of the canvas in the left-right direction so that it extends in the front-to-back direction. The awning cloth has a multi-layer structure having a surface fabric forming the outer surface of the awning cloth and a back fabric forming the inner surface of the awning cloth. The bicycle child seat cover according to Configuration 2, wherein the strip-shaped fabric is sewn only to one of the surface fabric and the back fabric and is not sewn to the other.

[0020] When this configuration is adopted, the strip-shaped fabric forming the core material pocket is sewn only to one of the surface fabric and the back fabric of the awning cloth and is not sewn to the other, so the seam does not penetrate the awning cloth and the waterproof property of the awning cloth is high. Therefore, it is possible to surely prevent water from entering from the awning cloth.

[0021] [Configuration 4] The bicycle child seat cover according to any one of Configurations 1 to 3, wherein the central spanning core material is attached to the outer surface side of the awning cloth, not the inner surface side of the awning cloth.

[0022] When this configuration is adopted, since the central spanning core material is attached to the outer surface side of the awning cloth, not the inner surface side of the awning cloth, even if a strong impact is applied in a situation where the strength of the child seat cover has decreased due to aging or the like and a part of the central spanning core material pops out, the central spanning core material will pop out to the outer surface side of the awning cloth and will not pop out to the inner surface side of the awning cloth. Therefore, it is possible to surely prevent the child inside the child seat cover from being injured and ensure high safety.

[0023] [Configuration 5] An awning bone accommodating sleeve for accommodating the rear awning bone and an upper rear cover portion continuous with the rear of the awning cloth are sewn to the rear edge of the awning cloth. The bicycle child seat cover according to any one of Configurations 1 to 4, wherein a waterproof tape extending in a strip shape along the seam is adhesively provided on the inner surface side of the seam between the awning cloth and the upper rear cover portion.

[0024] With this configuration, waterproof tape is attached to the inner side of the seam between the canvas and the upper rear cover, so even if it rains continuously while the bicycle is parked, it can be reliably prevented from seeping into the cover through that seam. [Effects of the Invention]

[0025] In this invention, the child seat cover for bicycles is supported by a central bridging core that spans the left-right central portion of the canvas fabric between the left-right central portion of the front canvas frame and the left-right central portion of the rear canvas frame. This ensures that the left-right central portion of the canvas fabric is held in a straight, ridge-like shape, preventing it from sagging downwards. In other words, the central bridging core creates a slope in the canvas fabric that slopes downwards from the left-right center toward both sides. Therefore, when it rains continuously while the bicycle is parked, the rainwater can be smoothly drained from the canvas fabric to the left and right, preventing water from accumulating on the canvas fabric and seeping into the cover.

[0026] Furthermore, since the central connecting core is detachable, the canopy can be folded compactly by removing the central connecting core before attaching the child seat cover to the child seat (for example, at the shipping stage). [Brief explanation of the drawing]

[0027] [Figure 1] This is a perspective view of a bicycle, seen from the front right, showing a child seat cover according to an embodiment of this invention attached to a child seat. [Figure 2] Figure 1 shows a perspective view of the area near the upper cover of the child seat cover, seen from the right rear. [Figure 3] Figure 1 shows a perspective view from the front right of the area near the window of the lower cover of the child seat cover, with the visor portion of the cover turned backward. [Figure 4] Figure 3 shows the state where the gripping part at the upper end of the window section is pulled down to open the left and right sliding fasteners simultaneously. [Figure 5]Figure 1 shows a perspective view of the area near the canopy of the child seat cover, seen from the upper right rear. [Figure 6] Cross-sectional view along the line VI-VI in Figure 5 [Figure 7] Cross-sectional view along line VII-VII in Figure 5 [Figure 8] (a) is a diagram showing the tip of the central bridging core shown in Figure 5 inserted into the core insertion opening, (b) is a diagram showing the end of the central bridging core shown in (a) pushed into the core insertion opening, and (c) is a diagram showing the central bridging core shown in (b) moved inside the core pocket in the opposite direction to the insertion direction. [Figure 9] (a) is a diagram showing the tip of the rear canopy frame shown in Figure 5 inserted into the canopy frame insertion opening, (b) is a diagram showing the end of the rear canopy frame shown in (a) pushed into the canopy frame insertion opening, and (c) is a diagram showing the rear canopy frame shown in (b) moved inside the canopy frame housing sleeve in the opposite direction to the insertion direction. [Modes for carrying out the invention]

[0028] Figure 1 shows a child seat cover 1 according to an embodiment of the present invention. This child seat cover 1 has an upper cover 3 that covers the top of the child seat 2 and a lower cover 4 that covers the front and sides of the child seat 2. The upper cover 3 is attached to the back of the child seat 2 (for example, the back of the headrest 5 portion of the child seat 2) using a child seat cover attachment belt (not shown). The lower cover 4 is connected to the upper cover 3 with a sliding fastener 6. In the figure, the child seat 2 is a rear child seat that is attached to the rear carrier 7 of a bicycle.

[0029] The upper cover 3 has a canvas 8 positioned above the child seat 2, an upper rear cover portion 9 connected to the rear of the canvas 8, and a canopy portion 10 extending forward from the canvas 8. The canopy portion 10 is a sunshade for the infant in the child seat 2 and is made of a light-blocking fabric. A pair of fasteners 11 are provided on the upper surface of the canopy portion 10 at a distance from each other, and the length of the canopy portion 10 can be shortened by folding the front portion of the canopy portion 10 upward and engaging the pair of fasteners 11 with each other.

[0030] The upper rear cover portion 9 is made of a flexible fabric. As shown in Figure 2, the upper rear cover portion 9 is held in an upward-bulging dome shape by a linear core material 12 that extends in the front-rear direction.

[0031] As shown in Figure 1, the lower cover 4 has a window portion 13 made of a transparent resin sheet and a skirt portion 14 that extends below the window portion 13. A linear core material 15 extending in the left-right direction is attached to the window portion 13, and this core material 15 holds the window portion 13 in a partially cylindrical shape that bulges forward, thereby securing space in front of the infant placed in the child seat 2.

[0032] Figure 3 shows the entire visor portion 10 of the upper cover 3 shown in Figure 1 folded back along the front edge 20 of the canvas 8. As shown in Figure 3, the slide fastener 6 consists of a right-side slide fastener 6 (towards the front of the page in the figure) that connects the right-side edges of the upper cover 3 and the lower cover 4, and a left-side slide fastener 6 (towards the back of the page in the figure) that connects the left-side edges of the upper cover 3 and the lower cover 4.

[0033] Both the right-side and left-side slide fasteners 6 are designed to allow the upper cover 3 and lower cover 4 to be released by moving the slider 16 from top to bottom. An opening 17 is provided between the upper ends of the right-side and left-side slide fasteners 6. By inserting a hand into this opening 17 and pulling down the gripping portion 18 located at the upper end of the window portion 13 of the lower cover 4, as shown in Figure 4, the lower cover 4 can be opened all at once.

[0034] As shown in Figure 5, the canvas 8 has a shape (so-called spindle shape) in which the front-to-back dimension is largest in the center in the left-to-right direction and gradually decreases toward both sides. The front edge 20 of the canvas 8 is supported by front canvas ribs 21 that extend in the left-to-right direction along the front edge 20 of the canvas 8, and the rear edge 22 of the canvas 8 is supported by rear canvas ribs 23 that extend in the left-to-right direction along the rear edge 22 of the canvas 8.

[0035] The front canopy frame 21 is provided to extend in an annular shape, passing sequentially through the right edge of the upper rear cover portion 9, the front edge 20 of the canopy fabric 8, and the left edge of the upper rear cover portion 9, in order to maintain the contour shape of the upper cover 3. The rear canopy frame 23 extends in an arc shape so that both the left and right ends of the rear canopy frame 23 correspond to both the left and right ends of the canopy fabric 8. The rear canopy frame 23 has the same length as the rear edge 22 of the canopy fabric 8. Here, the rear canopy frame 23 is rotatable in the front-rear direction with its left and right ends as pivot points.

[0036] The front edge 20 of the canvas 8 is held in a C-shape by the elasticity of the front canvas frame 21, opening downwards from the center of the front edge 20 in the left-right direction toward both sides, and similarly, the rear edge 22 of the canvas 8 is also held in a C-shape by the elasticity of the rear canvas frame 23, opening downwards from the center of the rear edge 22 in the left-right direction toward both sides, and similarly.

[0037] A central bridging core material 24 is attached to the left-right central portion of the canvas 8, spanning in the front-to-back direction between the left-right central portion of the front canvas frame 21 and the left-right central portion of the rear canvas frame 23. The central bridging core material 24 is a linear member made of resin or metal. The central bridging core material 24 is housed in a core material pocket 26 (see Figure 6) formed by sewing a strip of fabric 25 to the canvas 8. The strip of fabric 25 is a strip of fabric that extends in the front-to-back direction from the left-right center of the front edge 20 of the canvas 8, through the inside of the canvas 8, to the left-right center of the rear edge 22 of the canvas 8.

[0038] As shown in Figure 6, the core material pocket 26 is a long, narrow gap extending in the front-to-back direction (in the figure, perpendicular to the plane of the paper) formed between the canvas 8 and the canvas fabric 25 by sewing the left and right side edges of the strip-shaped fabric 25 to the canvas fabric 8. The canvas fabric 8 has a three-layer structure consisting of an outer fabric 27 that forms the outer surface of the canvas fabric 8, a lining 28 that forms the inner surface of the canvas fabric 8, and a cushion sheet 29 sandwiched between the outer fabric 27 and the lining 28. The strip-shaped fabric 25 is sewn only to the outer fabric 27 of the outer fabric 27 and lining 28 that form the canvas fabric 8, and is not sewn to the lining 28. The outer surface of the outer fabric 27 is treated with a water-repellent finish.

[0039] As shown in Figures 8(a) to 8(c), the longitudinal end of the strip-shaped fabric 25 is provided with a core material insertion opening 30 for inserting a central bridging core material 24 into a core material pocket 26, and a protrusion prevention piece 31 that covers the core material insertion opening 30 to prevent the end of the central bridging core material 24 from protruding out of the core material insertion opening 30. The protrusion prevention piece 31 is provided so as to be folded back from the longitudinal end of the strip-shaped fabric 25 to the opposite side in the longitudinal direction, and a hook-and-loop fastener 33 is attached to its surface, which is detachably engaged with a hook-and-loop fastener 32 provided around the core material insertion opening 30.

[0040] The core material insertion opening 30 is positioned such that its opening edge is offset inward in the longitudinal direction of the core material pocket 26, within a range of 10 mm to 25 mm from the outermost point in the longitudinal direction of the core material pocket 26. As a result, as shown in Figure 8(c), when the central bridging core material 24 is inserted into the core material pocket 26, the core material insertion opening 30 is positioned inward in the longitudinal direction from the end of the central bridging core material 24, thereby preventing the end of the central bridging core material 24 from unexpectedly protruding from the core material insertion opening 30.

[0041] As shown in Figure 5, the central bridging core 24 supports the central portion of the canvas 8 in the left-right direction, preventing it from sagging downwards, as shown in Figure 2.

[0042] As shown in Figures 5 and 7, a canopy frame housing sleeve 34, which houses the rear canopy frame 23, and an upper rear cover portion 9, which is connected to the rear of the canopy 8, are sewn to the rear edge 22 of the canopy fabric 8. Also, as shown in Figure 7, a waterproof tape 35 extending in a strip along the seam is adhered to the inner surface of the seam between the canopy fabric 8 and the upper rear cover portion 9. As the waterproof tape 35, for example, a film made of a resin such as polyurethane, or a cloth tape that has been treated with a waterproof coating such as resin can be used.

[0043] As shown in Figures 9(a) to 9(c), the longitudinal end of the canopy frame housing sleeve 34 is provided with a canopy frame insertion opening 36 for inserting the rear canopy frame 23 into the canopy frame housing sleeve 34, and a protrusion prevention piece 37 that covers the canopy frame insertion opening 36 to prevent the end of the rear canopy frame 23 from protruding out of the opening. The protrusion prevention piece 37 is provided so as to sandwich the opening portion of the canopy frame insertion opening 36 of the canopy frame housing sleeve 34, and by engaging a pair of hook fasteners 38 attached to the surface of the protrusion prevention piece 37, it is possible to maintain a state in which the canopy frame insertion opening 36 is covered (see Figure 5).

[0044] The canopy frame insertion opening 36 is positioned such that its opening edge is offset inward in the longitudinal direction of the canopy frame housing sleeve 34, within a range of 10 mm to 25 mm from the outermost end of the canopy frame housing sleeve 34 in the longitudinal direction. As a result, as shown in Figure 9(c), when the rear canopy frame 23 is inserted into the canopy frame housing sleeve 34, the canopy frame insertion opening 36 is positioned inward in the longitudinal direction from the end of the rear canopy frame 23, thereby preventing the end of the rear canopy frame 23 from unexpectedly protruding from the canopy frame insertion opening 36.

[0045] Now, let's consider the case where the central bridging core material 24 shown in Figure 5 is not provided in the canvas 8. In this case, the rear canvas frame 23 is rotatable relative to the front canvas frame 21, so there is almost no tension on the canvas 8. As a result, wrinkles may form in the center of the canvas 8 in the left-right direction, causing it to sag under its own weight. Therefore, if it rains continuously while the bicycle is parked, the rainwater does not flow down from the canvas 8 to the sides, but tends to accumulate on the canvas 8. Once rainwater accumulates on the canvas 8, the weight of the rainwater causes the canvas 8 to sag more and more, resulting in an accumulation of even more rainwater. In this case, some of the large amount of rainwater accumulated on the canvas 8 may gradually seep into the inside of the cover through the seams of the canvas 8, potentially causing the seat surface of the child seat 2 to get wet.

[0046] To address this problem, the child seat cover 1 of the above embodiment, as shown in Figure 5, has a central bridging core 24 positioned to span between the central left-right portion of the canvas 8 and the central left-right portion of the rear canvas rib 23, so that the central left-right portion of the canvas 8 is held in a straight, ridge-like shape so as not to sag downwards. In other words, the central bridging core 24 creates a slope in the canvas 8 that slopes downwards from the center of the canvas 8 toward both the left and right sides. Therefore, when it rains continuously while the bicycle is parked, the rainwater can be smoothly drained from the canvas 8 to the left and right, preventing water from accumulating on the canvas 8 and seeping into the cover.

[0047] Furthermore, as shown in Figures 8(a) to 8(c), the central connecting core 24 of the child seat cover 1 is detachable. Therefore, before attaching the child seat cover 1 to the child seat 2 (see Figure 1) (for example, at the shipping stage), the central connecting core 24 can be removed, allowing the canvas 8 to be folded compactly.

[0048] Furthermore, since the core material insertion opening 30 shown in Figure 8(c) of this child seat cover 1 is covered with a pop-out prevention piece 31 as shown in Figure 5, it is possible to reliably prevent the end of the central connecting core material 24 from popping out of the core material insertion opening 30 even when an unexpected external force or impact is applied to the front canopy frame 21 or the rear canopy frame 23.

[0049] Furthermore, as shown in Figure 6, the child seat cover 1 has a strip of fabric 25 forming the core material pocket 26 which is sewn only to the outer fabric 27 of the canvas 8 and not to the inner fabric 28. As a result, the seams do not penetrate the canvas 8, and the canvas 8 has high water resistance. Therefore, it is possible to reliably prevent water from seeping in from the canvas 8.

[0050] Furthermore, as shown in Figure 6, the child seat cover 1 has a strip of fabric 25 for attaching the central connecting core material 24 sewn to the outer fabric 27 that forms the outer surface of the canvas 8, rather than to the lining 28 that forms the inner surface of the canvas 8. In other words, since the central connecting core material 24 is attached to the outer surface of the canvas 8 rather than the inner surface, even if a strong impact is applied when the strength of the child seat cover 1 has decreased due to aging or other reasons, and a part of the central connecting core material 24 pops out of the core material pocket 26, that central connecting core material 24 will pop out to the outer surface of the canvas 8, not to the inner surface of the canvas 8. Therefore, it is possible to reliably prevent injuries to infants inside the child seat cover 1 and ensure a high level of safety.

[0051] Furthermore, as shown in Figure 7, this child seat cover 1 has waterproof tape 35 attached to the inner side of the seam between the canvas 8 and the upper rear cover portion 9, so even if it rains continuously while the bicycle is parked, it can reliably prevent water from seeping into the cover through the seam.

[0052] In the above embodiment, the bicycle child seat cover 1 was described as an example of a type that covers a rear child seat 2 attached to the rear carrier 7 of a bicycle, as shown in Figure 1. However, this invention can also be similarly applied to a type that covers a front child seat attached to the handlebars of a bicycle.

[0053] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
