Abstract

To achieve a stable running state of a bicycle by reducing, even when receiving front wind or cross wind, a wind pressure thereof, while ensuring a space around the face of an infant for maintenance of comfort.SOLUTION: A linear frame body 26 supporting a cover body of a child seat cover for bicycle is structured so that an elastic linear material in a signal linear shape is crossed on the back side of a child seat and supporting frames 26A, 26B extending so that a surrounding region spreads from a cross portion X to the forward side (opposite side to an arrow BR) by being folded back in an axial symmetry shape at the cross portion are formed in series. When cross wind W is received, as shown in an arrow W1, the cross wind is easy to escape backward in a bicycle running direction (the arrow BR direction), thus alleviating a wind pressure. The lower side of the cover body with low linear material strength follows the magnitude of the wind pressure and as shown by a chain double-dashed line, becomes deformed flexibly, so that a flow channel escaping the cross wind downward is formed (an arrow W2) and the wind pressure is alleviated.SELECTED DRAWING: Figure 1

Description

The present invention relates to a child seat cover for a bicycle that is used by being attached to a child seat fixed to either the front or the back or the front or the back of the bicycle.

Bicycle child seats for the stable seating of infants on bicycles are generally fixed using the U-shape of the handlebar on the front side of the bicycle and on the loading platform on the rear side. .. The configuration of this type of child seat includes, for example, a seat body portion having a backrest portion integrally, a headrest portion provided on the upper back surface of the seat body portion to protect the infant's head, and a lower front side of the seat body portion. It is known that a footrest portion provided and a hand grip portion integrally provided on the seat body portion on the front side of the seat body portion are provided, and the seat body is mainly made of a synthetic resin material. Various configurations have been developed in which the positions of the headrest portion and the footrest portion can be adjusted so as to cope with the difference in height and growth of infants.

A bag-shaped cover that covers the circumference of the infant sitting on the child seat is detachably attached to the child seat to protect it from the rain and wind and protect it from the cold. This type of child seat cover is roughly composed of a side surface portion that covers both sides of the infant and a ceiling surface portion that covers the upper part and the front side of the infant's head, and the ceiling surface portion can be attached to and detached from the side surface portion by a slide fastener or the like. It has become. When it is not necessary to prevent rain and wind, the ceiling surface is partially opened so that it can be directly exposed to the outside air (see Patent Document 1). In addition, at least a part of the child seat cover is made of a transparent material in order to remove the anxiety of the infant and to check the appearance of the infant inside the seat from the outside. From the perspective of the infant, whose surroundings are covered with the child seat cover, at least a certain amount of gap (space) is required between the child seat cover and the head area (face area) in order to obtain comfort.

This type of child seat cover generally has a bag-like structure formed by connecting a plurality of flexible seats with a slide fastener or the like. Therefore, although a certain degree of three-dimensional shape retention can be obtained, it easily bends and does not return to its original shape when it receives wind pressure, etc., and the seat remains in contact with or close to the infant's face, impairing comfort. Often

In order to deal with this problem, Patent Document 2 has a configuration in which the outer peripheral edges of a pair of side seats are supported by elastically deformable smooth closed-loop independent frame portions to maintain the planar shape of the side seats. Infant seat covers have been proposed. According to this infant seat cover, the side seats are held independently on the outside of the seat body due to the strength of the frame portion, so that the ceiling seats arranged between the pair of side seats are also constant. Since it is held at a height, a certain space is secured around the infant's head. That is, the configuration described in Patent Document 2 ensures the independence of the pair of side seats as a flat surface by the rigidity of each frame portion based on the independent closed loop shape, and this rigid support function is also applied to the ceiling seat and the like. It is based on the idea of improving the shape retention of the entire cover.

Japanese Patent No. 5767742 Japanese Patent No. 5279728

However, in the configuration described in Patent Document 2, although the wind (front wind) received from the front in the traveling direction of the bicycle has a certain shape-retaining strength, when a strong crosswind is received while the bicycle is traveling, the side seat Due to its high independence, the wind pressure of the crosswind is received by the entire side seat, which may cause the bicycle to run unstable. In other words, if the side seats along the running direction of the bicycle maintain flatness and a crosswind hits it, the wind pressure will be applied as if the crosswind hits the flat plate at a right angle. become. Therefore, it is easy to ride a bicycle on a windy day, and even in bad weather, the cover may be hesitant to use.

On the other hand, this type of child seat cover is generally covered with a plastic sheet or the like to protect against rain and wind and to protect against the cold. For this reason, it is difficult to use the cover with the ceiling surface closed due to the high temperature inside the cover during the summer when the temperature is high, so it is comfortable as a cover for insects such as mosquitoes that occur in the summer. I couldn't hope to use it.

The present invention was devised in view of this situation, and while maintaining comfort by securing a space around the head of an infant, the wind pressure is reduced even if a front wind or a crosswind is received, and the bicycle The purpose is to make it possible to obtain a stable running condition.

Another object of the present invention is to cover the area around the infant in a repellent and airy manner even in the summer when the temperature is high and insects such as mosquitoes occur so that a comfortable use state can be obtained. To be.

In order to achieve the above object, in the present invention, the frame for ensuring the three-dimensional shape retention of the cover has the strength for maintaining a comfortable space and the wind is deformed to follow the crosswind. It has a structure that also has the suppleness to let it escape.

Further, in order to achieve the above-mentioned other object, the present invention has a structure in which the cover is provided with air permeability so that insects can be repelled without heat being trapped inside even in the use state where the upper surface side is closed.

Specifically, the child seat cover for a bicycle of the present invention is a child seat cover for a bicycle used by being attached to a child seat fixed to the front side and / or the rear side of the bicycle, and includes a cover body fixed to the child seat. At least a part of the cover body is detachably connected to the cover body to form a three-dimensional bag-like top cover, and the cover body has an elastic single wire on the back side of the child seat. It has a linear frame body in which a series of support frames are formed so as to expand the surrounding area from the intersecting portion to the front side of the child seat by being bent back in a line-symmetrical manner at the intersecting portion. Is what you are doing. With this configuration, the cover body forms a curved surface whose area converges toward the back side of the child seat, and it becomes easy for the crosswind to escape to the back side. The upper side of the cover body, which has high strength due to the connection with the top cover, is not easily deformed by crosswinds, and a comfortable space around the infant's face is maintained. Since the lower side of the cover body has low strength, the follow-up deformability with respect to the crosswind is improved and the crosswind can be easily released.

The linear frame is preferably configured so that the strength of the wire on the upper side of the cover body is higher than the strength of the wire on the lower side. With this configuration, it is possible to mainly impart the following deformability to the crosswind on the lower side of the cover body, improve the three-dimensional shape retention as the cover by the strength on the upper side, and secure a comfortable space around the face of the infant. ..

It is preferable that a single wire rod is doubly arranged on the upper side of the cover body. With this configuration, it is possible to improve the strength of the upper side of the cover body regardless of the configuration of the upper surface cover. By simply increasing the length of the single wire rods constituting the linear frame and arranging them, it is possible to easily form a portion to be double-arranged.

It is also preferable that a single wire rod different from the single wire rod constituting the linear frame is arranged on the upper side of the cover body to form a double layer. With this configuration, it is possible to improve the strength of the upper side of the cover body regardless of the configuration of the upper surface cover.

The upper surface cover has a linear frame body for the upper surface on the outer peripheral edge thereof, and the number of wires arranged at the connecting portion with the cover body is two or more including the wire rods constituting the linear frame body for the upper surface. Is preferable. By coexisting with the wire rod of the linear frame for the upper surface, the strength of the upper side of the cover body can be further improved.

It is further preferred that at least one of the cover body and the top cover has a flexible mesh sheet. With this configuration, functions such as insect repellent can be obtained.

According to the present invention, it is possible to secure a space around the head of an infant to maintain comfort, reduce the wind pressure even if a front wind or a cross wind is received, and obtain a stable running state.

Further, according to the present invention, it is possible to obtain a comfortable use state by covering the periphery of the infant so as to repel insects even in the summer when the temperature is high and insects such as mosquitoes occur.

Hereinafter, a child seat cover for a bicycle (hereinafter, abbreviated as a child seat cover or simply a cover) according to an embodiment of the present invention will be described with reference to the drawings. In the present specification, the front side and the rear side refer to the front side and the rear side in the running direction of the bicycle, and the description including the front and rear characters also conforms to this direction. Further, the upper side and the lower side refer to the upper side and the lower side in the height direction of the child seat fixed to the bicycle, and the description including the upper and lower characters also conforms to this direction.

FIG. 2 shows a usage state of the front child seat cover 2A according to the present embodiment. The child seat cover 2A is detachably attached to the child seat 8 fixed to the front side of the bicycle 4 by using the U-shape of the handle 6. An infant 12 wearing a helmet 10 sits on the child seat 8 with a seatbelt 13 (see FIG. 13) and a hand grip portion 14 gripped. The height (upper surface position) of the child seat cover 2A after mounting is set so as not to block the view of the driver 16.

The child seat cover 2A used for rain / wind protection or cold protection is a cover body 18 that covers both sides and a part of the back side of the infant 12 sitting on the child seat 8, and at least a part of the cover body 18 is removable. A top cover 20 that is connected to the cover body 18 to form a three-dimensional bag shape that covers the upper half of the infant 12, and a bag-shaped leg that is connected below the cover body 18 and covers the leg of the infant 12. It has a part cover 22 and the like. The top cover 20 has an oval shape that covers not only the upper side of the infant 12 but also a part of the front side and the back side.

FIG. 3 shows the cover main body 18, the leg cover 22 connected to the cover main body 18, and the upper surface cover 20, and the cover main body 18 and the leg cover 22 cut the central portion of the leg cover 22. It is developed in a plane. The leg cover 22 is actually in the shape of a bag made of a single piece of cloth, but in FIG. 3, a part is virtually cut and developed in order to show it in a plane, and reference numerals 22a and 22b are the cuts. Shows the line. Further, the cover body 18 and the leg cover 22 show the state of the child seat cover 2A as viewed from the back side in the bicycle traveling direction.

The cover body 18 that covers both sides and a part of the back surface of the infant 12 is composed of a left wide surface portion 18A, a right wide surface portion 18B, and a back surface portion 18C that is connected to these in an endless manner. These surfaces are formed of a synthetic resin sheet such as nylon or PVC for waterproofing, and are supported by a single linear frame 26 (see FIG. 4). The left wide surface portion 18A and the right wide surface portion 18B are mainly composed of a transparent region 18a for visually recognizing the outside and the inside, and a ventilation region 18b capable of taking in outside air, respectively, and the back surface portion 18C is mainly a child seat 8. As a fixed area for. The boundaries between the left wide surface portion 18A and the right wide surface portion 18B and the back surface portion 18C are not clearly distinguished, but they are partitioned in FIG. 3 and the like for the sake of clarity.

The transparent region 18a is provided to remove the anxiety of the infant 12 due to the obstruction of the field of view and to confirm the state of the infant 12 inside the seat from the outside. A semi-transparent or opaque synthetic resin sheet is used for the regions other than the transparent region 18a because they are positioned as private regions that are not often seen from the outside. Of course, a transparent synthetic resin sheet may be used in these areas as well. As shown in FIG. 6, the ventilation region 18b has a configuration in which the mesh sheet 27 for ventilation is exposed when the outer side of the cover is turned over to take in outside air. As a result, it is possible to prevent the temperature inside the cover from rising and impairing comfort. The sheet material forming the surface of the cover body 18 is not limited to the synthetic resin sheet as long as it is practical for rain and wind protection and cold protection, and a rubberized cloth or the like can also be used.

As shown in FIG. 3, a belt 28 for inserting the tip end side of the upper surface cover 20 when the upper surface cover 20 is opened and accommodating it compactly is attached to the back surface portion 18C as a fixed region by fixing only both ends. (See FIG. 7). The belt 28 also has a function as a reinforcing member that regulates the elongation of the cover. A fixing belt 30 is attached to the inside of the back surface portion 18C as a fixing means for fixing the child seat cover 2A to the child seat 8. These fixing belts 30 have an adjuster 30a such as a D-can, for example, and are wound around the fixing portions 32a and 32b of the headrest portion 32 of the child seat 8 shown in FIG. 8, and the belt end portion is passed through the adjuster 30a and tightened. It is fixed by that. Note that the seat belt 13 is omitted in FIG.

As shown in FIG. 3, a tightening member 34 is provided between the ventilation regions 18b for narrowing the bulge (looseness) of the cover and keeping the height of the cover (position of the upper surface cover 20) predetermined. The tightening member 34 is composed of a belt 34a having one side (concave portion) of the buckle and a belt 34b having the other side (convex portion) of the buckle, and can be tightened and released by one-touch operation. By fastening the tightening member 34, the distance between the lower part of the support frame 26A constituting the linear frame body 26 described later and the lower part of the support frame 26B becomes closer on the back side, so that the support frame 26A and the support frame 26B move up and down. It becomes easy to take a form extending in the direction, and the position of the top cover 20 is kept high. Therefore, the tightening member 34 is arranged between the cross point X of the linear frame body 26 described later and the lower end of the support frame 26A (support frame 26B). In the present embodiment, the tightening member 34 is arranged substantially in the middle of the cross point X and the lower end of the support frame 26A (support frame 26B), and is fixed to the piping covering the support frames 26A and 26B. There is. When the cover is attached to or detached from the child seat 8, the tightening member 34 is disconnected in order to widen the frontage of the cover.

The leg cover 22 is also made of a synthetic resin sheet for waterproofing, and through holes 36 for passing the handle 6 of the bicycle 4 are formed on both front sides. The through hole 36 is opened and closed by a vertically long and narrow surface fastener, and the gap after passing through the handle 6 can be closed to prevent rain from blowing in (see FIG. 9). A draw cord 38 is passed through the lower end of the leg cover 22 over the entire circumference, and as shown in FIG. 10, it can be squeezed like a purse with a squeezing tool 39 on the back side. Further, as shown in FIG. 3, a hook-and-loop fastener 40 for fixing the front end portion of the upper surface cover 20 when the cover is closed is provided on the front side of the leg cover 22. The leg cover 22 is also positioned as a private area, and a translucent or opaque synthetic resin sheet is used. Of course, a transparent synthetic resin sheet may be used. The leg cover 22 is not limited to the synthetic resin sheet as long as it is practical for rain and wind protection and cold protection.

As shown in FIG. 3, the linear frame body 26 is substantially covered with piping, and one side 44a of a double-opening open fastener as a means of connecting to the upper surface cover 20 is provided on the upper surface side of the cover main body 18. There is. In the present embodiment, the upper surface cover 20 is provided with the upper surface linear frame body 46 on the entire circumference of the outer peripheral edge thereof, and has a configuration in which the upper surface linear frame body 46 supports the synthetic resin sheet 48. The upper surface linear frame 46 is covered with piping, and the other side 44b of the open fastener is provided over the entire circumference except for the front end portion thereof. Reference numerals 44b-1 and 44b-2 indicate both ends of the other side 44b of the open fastener, and sliders (not shown) are provided at both ends so that both ends can be opened. When the top cover 20 is opened, it can be easily operated by holding the front end portion 48b, which is not closed by the open fastener, by hand and moving the sliders on both sides. The closed portion by the open fastener is covered with piping of the cover main body 18 and the upper surface cover 20, and is covered with the convex edge 48a of the synthetic resin sheet 48 to be waterproof. The synthetic resin sheet 48 is transparent so that the driver 16 can see the state of the infant 12 and can collect light, but the synthetic resin sheet 48 is not limited to this. On the back side of the tip of the top cover 20, a hook-and-loop fastener 50 that engages with the hook-and-loop fastener 40 of the leg cover 22 is provided so that the top cover 20 can be kept in an open state. In addition, the open fastener is displayed as a single line by omitting sliders and teeth as appropriate.

Next, the linear frame body 26 forming the framework of the cover main body 18 and the upper surface linear frame body 46 of the upper surface cover 20 will be described with reference to FIG.

The linear frame body 26 is formed by intersecting an elastic single linear wire rod on the back surface side of the child seat 8 and bending it back in a line symmetry (substantially inverted 8-shaped) at the intersecting portion to form an intersecting portion (hereinafter, cross). The support frames 26A and 26B extending from the point) so as to expand the surrounding area in the direction corresponding to the front side of the child seat 8 are formed in a series. The linear frame body 26 is formed by bending a single linear stainless thin wire 52 having a linearly processed spring elasticity into a curved shape. In the present embodiment, a thin stainless steel wire having a diameter of 1.2 mm is used as the wire rod, but the material and diameter of the wire rod are not limited to this.

To explain the bending shape of the stainless thin wire 52 in a trace manner, for example, it extends from the start point S so as to form an upper contour of the left wide surface portion 18A, and then descends through the cross point X. After that, it extends so as to form the lower contour of the right wide surface portion 18B, and then folds back and extends so as to form the upper contour of the right wide surface portion 18B. Subsequently, it is curved in a concave shape above the cross point X so as to approach the cross point X, then descends along the upper contour of the left wide surface portion 18A, and is folded back so as to form the lower contour of the left wide surface portion 18A. Pass point X. Then, it extends along the upper contour of the right wide surface portion 18B and then descends to the end point E.

Due to this unique bending (bending) configuration of the wire rod, the support frames 26A and 26B supporting the left wide surface portion 18A, the right wide surface portion 18B and the back surface portion 18C are lined with reference to the center line H on the back side passing through the cross point X. It is formed in a series symmetrically, and the portion corresponding to the upper side of the cover main body 18 has a configuration in which wire rods are doubly arranged. The stainless thin wires 52 that intersect at the cross point X are not fixed to each other. Therefore, although the support frames 26A and 26B are constrained in a crossing manner by the piping of the back portion 18C, they can be slightly displaced, and the wire rods at the locations where the wind pressure such as the front wind or the cross wind is received are present. It has a structure that can be moved freely.

As shown in FIG. 5, when the left wide surface portion 18A receives wind pressure of a front wind or a cross wind, the support frame 26A can bend downward with the cross point X as a fulcrum, and when the wind weakens, the spring elasticity of the wire rod Returns to the original shape (position) with. The same applies when the right wide surface portion 18B receives wind pressure of a front wind or a cross wind. That is, the lower region N between the support frames 26A and 26B indicated by hatching in FIG. 5 allows the support frames 26A and 26B to bend and deform due to wind pressure. In other words, the lower region N becomes a cover contractible space for deforming and releasing the lower region N when it receives wind pressure. As a result, the degree of freedom of wind pressure relief against front winds and crosswinds is secured.

In the present specification, the term "single wire" means not only a single wire but also a bundle of a plurality of thin wires and a litz wire.

As described above, the stainless thin wire 52 as a wire rod is doubly arranged on the upper side of the cover main body 18 including the back side. Therefore, the upper side of the cover main body 18 has a higher wire strength than the lower side of one stainless thin wire 52. The concave curved portion 52a of the stainless thin wire 52 above the back surface portion 18C (above the cross point X) has a curvature along the convex curved portion 46a on the back surface side of the upper surface linear frame body 46. In FIG. 4, reference numeral R1 indicates an arrangement area of the open fastener on the cover main body 18, and R2 indicates an arrangement area of the open fastener on the upper surface cover 20. The upper surface linear frame body 46 is formed of the same stainless thin wire 52 as the linear frame body 26, and the ends are crimped or welded with a connector to form a completely closed loop shape. Therefore, in a state where the upper surface cover 20 is connected to the cover main body 18 with an open fastener, the number of wire rods arranged at the connecting portion is 3 (two or more), and the wire rod strength is further increased.

From the state shown in FIG. 4, the linear frame body 26 is curved on the back surface portion 18C side so that the left wide surface portion 18A and the right wide surface portion 18B face each other with the cross point X as the center, as shown in FIG. Can be folded. As a result, the surface partitioned by the support frames 26A and 26B becomes a curved surface whose vertical width narrows (converges) toward the intersection. Due to this smooth three-dimensional curved surface, as shown in FIG. 1, when a crosswind W is received, the bicycle 4 is easily released to the rear in the traveling direction (arrow BR direction) as shown by the arrow W1, and the wind pressure is reduced. Further, when the crosswind W is received, the lower side of the cover body 18 having a small wire rod strength is flexibly deformed according to the magnitude of the wind pressure as shown by the alternate long and short dash line. At the same time, the leg cover 22 connected below the cover body 18 is also deformed. As a result, a curved recess for letting the crosswind escape downward is formed in the right wide surface portion 18B, and as shown by the arrow W2, for example, the wind is guided downward and flows, and the wind pressure is reduced. The direction of the curved recess for letting the wind escape is randomly formed according to the degree of wind contact. When the wind pressure is no longer applied, the original cover shape is immediately restored by the elasticity of the wire rod on the lower side of the cover body 18. The same applies when the left wide surface portion 18A receives a crosswind. In FIG. 1, the linear frame body 26 is shown schematically, and piping, open fasteners, and the like are omitted.

In this way, even if a crosswind is received, the lower side of the cover body 18 is deformed to escape the crosswind (nothing), and the wind pressure can be reduced, so that a stable running state of the bicycle can be obtained even when the wind is strong. Can be done. The three-dimensional shape retention of the cover and the comfortable space around the face of the infant 12 are secured on the upper side of the cover body 18 having a large wire rod strength. Further, deformation due to wind from the front in the traveling direction is also prevented by the wire strength on the upper side of the cover body 18. The non-closed configuration (displaceable configuration) of the support frames 26A and 26B at the intersections described above assists the flexible deformation of the cover body 18 with respect to crosswinds. Even if the cross point X of the linear frame body 26 is fixed by welding or the like, the above-mentioned effect on the crosswind can be obtained. This crosswind relief function is exhibited in combination with the cover contraction function having the cross point X as a fulcrum described with reference to FIG.

As in the present embodiment, by making the wire strength different between the upper side and the lower side of the cover body 18, the wind pressure reduction function due to the supple deformation when receiving a crosswind, the comfortable space around the face of the infant, and the three-dimensional maintenance. It is possible to achieve both the function of maintaining the shape.

It should be noted that the wind escape function due to the flexible deformation of the cover body 18 when receiving a crosswind can be obtained not only when the bicycle is running but also when the cover body 18 is standing only on the stand, and has the effect of preventing the bicycle from falling over.

In the present embodiment, three stainless thin wires 52 are arranged on the upper side of the cover main body 18, but the wire rod strength for maintaining the three-dimensional shape retention of the cover is sufficient due to the size of the diameter of the stainless thin wires 52. In the case of obtaining the above, the linear frame 46 for the upper surface of the upper surface cover 20 is not always necessary. When the strength of the wire on the upper side of the cover body 18 is sufficient to maintain the three-dimensional shape of the cover, the diameter of the wire of the linear frame 46 for the upper surface is made smaller than that of the thin stainless wire 52 to cover the top cover 20. The handleability (shape retention) may be ensured.

FIG. 4 shows an example in which one thin stainless steel wire 52 is bent to form a linear frame body 26, but as shown in FIG. 12, a linear frame body 54 closed in a substantially inverted 8-character shape and a wire rod The linear frame body 58 may be formed by combining with a separate M-shaped reinforcing wire rod (another single linear wire rod) 56 arranged in a range for increasing the strength. The reinforcing wire 56 is also made of thin stainless steel wire 52 like the linear frame body 54.

FIG. 13 shows a state in which the upper surface cover 20 is left open, that is, a state in which the open fastener is partially opened. When the connection with the upper surface cover 20 is lost, the cover main body 18 can be greatly deformed, whereby the frontage for getting on and off the infant 12 is greatly opened. This type of child seat cover is often used as a permanent seat cover because it is a little troublesome to attach to the child seat. However, according to the child seat cover 2A of the present embodiment, it is easy to get on and off the vehicle in the permanent seat, and the vehicle can run. Sometimes it can be a smart three-dimensional shape. Since the upper surface cover 20 has a linear frame body 46 for the upper surface having spring elasticity, the open fastener is not opened and bent to the back side as it is. In this case, as shown in FIG. 14, if the open portion of the top cover 20 is twisted in the middle, it crosses and overlaps in a circular shape, so that a compact open state can be obtained. The overlapped upper portion (tip portion) is shifted, and as described above, the child seat cover 2A is inserted into the inner side of the belt 28 provided on the back side to accommodate the child seat cover 2A.

Another embodiment of the present invention will be described with reference to FIG. The child seat cover 2A in the above embodiment was for rain and wind protection and cold protection, but the child seat cover 2B according to the present embodiment is for insect repellent in a high temperature period such as summer. Since the configuration of the linear frame body 26 and the opening / closing configuration by the open fastener are the same as those in the above embodiment, the same reference numerals are given and the description thereof will be omitted, and only the necessary parts will be described.

In the child seat cover 2B, most of the cover main body 18 and the leg cover 22 are covered with a flexible mesh sheet material (mesh sheet) 60. If the entire area is covered with a flexible mesh-like sheet material, the sheet material may stretch and its shape may change over time. Therefore, in order to prevent this, a non-mesh cloth material 62 is provided at an appropriate place. Have been placed. Specifically, the cloth material 62 is arranged in a portion corresponding to each ventilation region 18b and the back surface portion 18C of the cover main body 18, and a part in front of the leg cover 22. Also in the upper surface cover 20, the cloth material 62 is arranged on a part of the back surface side and the tip portion. In the present embodiment, since the cover has air permeability as a whole, the portion corresponding to the air vent region 18b does not have the fold structure shown in FIG.

According to the child seat cover 2B of the present embodiment, since most of the cover is covered with the mesh-like sheet material 60, the air permeability is good and the temperature rise inside the cover can be suppressed even in a high temperature such as summer. At the same time, it can repel insects such as mosquitoes and provide comfort. The location of the cloth material 62 and the area ratio of the mesh sheet are not limited to the above.

In each of the above embodiments, the front seat is mounted on the child seat fixed to the front side of the bicycle, but the child seat fixed to the bicycle carrier can be similarly mounted and used for the rear seat. .. In the case of the rear seat, the child seat itself is larger than that of the front seat, and the shape of the cover itself that covers it is also larger. Therefore, the diameter of the stainless thin wire 52 may be increased (for example, 1.4 mm) to increase the wire strength. It is desirable to place a fixing belt or the like on the handle of the child seat to improve the three-dimensional shape retention of the cover.

Further, in the above embodiment, the thin stainless steel wire is used as the wire rod, but other materials having spring elasticity may be used, and the wire rods of different materials may be used in the portion to be the double wire.

The present invention is not limited to the above-described embodiment, and various design-modified forms within the scope of the invention described in the claims are also included in the technical scope.
