Description

Child seat for bicycle

Technical Field

The present invention relates to a child seat for a bicycle.

Background

Child seats for bicycles, which are mounted on bicycles for seating children, are widely spread. In addition, there is known a canopy (or sunshade) for shielding a child seated in a child seat from above and providing a sunshade environment for the child.

However, the canopy disclosed in JP2006-015920a is fixed so as not to be movable relative to the seat surface of the child seat. The canopy thus mounted is of sufficient size (in particular height) to be able to cover children of various heights. However, when a bicycle is stored in a limited space such as a parking lot, the large-sized canopy may interfere with surrounding objects and hinder storage. Similar problems occur in a child seat for a bicycle to which a supporting device such as a rain cover for supporting the child seat is attached.

Detailed Description

Fig. 1 to 9 are views for explaining one embodiment of a child seat for a bicycle according to the present invention. In fig. 1 thereof, the overall construction of a bicycle with a child seat is shown. As shown in fig. 1, a child-seat-equipped bicycle 1 of the present embodiment includes a child seat 10 and a bicycle 2 having the child seat 10 mounted on a rear portion thereof. In the example shown in fig. 1, the bicycle with child seat 1 further comprises a second child seat 100 mounted at a front portion of the bicycle 2.

In the present specification, unless otherwise specified, terms "front", "rear", "upper", "lower", "front-rear direction", and "up-down direction" of the bicycle 2 refer to "front", "rear", "upper", "lower", "front-rear direction", and "up-down direction" based on a rider riding the bicycle 2. Therefore, the "front-rear direction" corresponds to the left-right direction of the paper surface in fig. 1. Unless otherwise specified, "front" means a side that a rider riding the bicycle 2 faces, and a right side of a paper surface in fig. 1 is a front side of the bicycle 2. On the other hand, the "up-down direction" refers to a direction orthogonal to the front-back direction and orthogonal to the ground plane. Therefore, when the ground plane is horizontal, "vertical direction" means vertical direction. The "width direction" refers to a lateral direction and is a direction orthogonal to both the "front-back direction" and the "up-down direction".

In the present specification, unless otherwise specified, the terms "front", "rear", "upper", "lower", "front-rear direction", "up-down direction", and "width direction" with respect to the child seat 10 and the respective portions of the child seat 10 refer to "front", "rear", "upper", "lower", "front-rear direction", "up-down direction", and "width direction" with reference to a child seated in the child seat 10 attached to the bicycle 2. Therefore, the "front-rear direction" corresponds to the left-right direction of the paper surface in fig. 1. Unless otherwise specified, "front" means a side facing the child seated in the child seat 10, and the right side of the drawing sheet in fig. 1 is a front side of the child seat 10 and the respective portions of the child seat 10. On the other hand, the "up-down direction" refers to a direction orthogonal to the front-rear direction and orthogonal to the ground contact surface of the bicycle 2. Therefore, when the ground plane is horizontal, the "vertical direction" refers to the vertical direction. The "width direction" refers to a lateral direction and is a direction orthogonal to both the "front-back direction" and the "up-down direction".

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As described above, the child seat equipped bicycle 1 includes the child seat 10, and the bicycle 2 with the child seat 10 mounted thereon.

First, the bicycle 2 will be explained. The bicycle 2 includes: a main frame portion 3 extending in a substantially front-rear direction; a front fork 4 connected to the front end of the main frame portion 3; a front wheel 5a rotatably supported at a lower end portion of the front fork 4; and a rear wheel 5b rotatably supported at a rear end portion of the main frame portion 3. The front fork 4 is rotatable about an axis extending substantially in the vertical direction with respect to the main frame portion 3. The front wheel 5a is rotatable about an axis line extending in the width direction of the front fork 4 with respect to the front fork 4. The rear wheels 5b are rotatable about an axis line extending in the width direction of the main frame portion 3 with respect to the main frame portion 3. Moreover, the bicycle 2 further comprises: a handle bar 6 connected to an upper end portion of the front fork 4; a saddle 7 supported by a seat tube 3a extending upward from the center of the main frame portion 3 in the longitudinal direction; and a shelf 8 provided behind the saddle 7 and above the rear wheel 5 b. The shelf 8 is supported by a shelf support member 3b extending upward from the rear end of the main frame portion 3.

The handlebar 6 is a member used by the rider to operate the steering of the front wheel 5 a. A handlebar 6 is fixed to the upper end of the front fork 4, said handlebar 6 being rotatable with the front fork 4 relative to the main frame part 3. Therefore, when the handle 6 is turned, the steering of the front wheel 5a held by the front fork 4 changes. The second child seat 100 is fixed to the upper end of the front fork 4 together with the handlebar 6.

Next, the child seat 10 will be explained with reference to fig. 1 to 9. Fig. 2 is a rear view of the bicycle child seat 10 shown in fig. 1, with a portion 22a of the rear wall portion 22 of the seat body 20 removed. Fig. 3 corresponds to fig. 2, and is a diagram showing a state in which the headrest 30 is movable with respect to the seat main body. Fig. 4 corresponds to fig. 2, and is a diagram showing a state in which the headrest 30 is moved with respect to the seat main body 20 from the position shown in fig. 2. Fig. 5 is a partial side view showing the headrest 30 and the canopy device 50 in the position shown in fig. 2. Fig. 6 is a partial side view showing the headrest 30 and the canopy device 50 in the position shown in fig. 4. Fig. 7 is a perspective view of the holder 51 attached to the headrest 30. Fig. 8 is a perspective view showing the canopy base 61 from the side opposite to the holder 51. Fig. 9 is a side view showing the support means 80 supporting the canopy member 76. Although some of the constituent elements included in the child seat 10 are shown in some of the drawings, the illustration of the constituent elements is omitted in other drawings. For example, in fig. 2 to 4, the canopy member 76 is not shown for clarity.

As shown in fig. 1, the child seat 10 includes a seat body 20 that houses a child, a headrest 30 attached to the seat body 20, and a canopy device 50. The child seat 10 is fixed to the shelf 8.

First, the seat body 20 will be explained. In the illustrated example, the seat body 20 includes a seat surface portion 21 and a rear wall portion 22 connected to the seat surface portion 21 from behind. The seat surface portion 21 is a portion facing the hip of the child seated in the child seat 10. The rear wall portion 22 is a portion opposed to the back of the child. As shown in fig. 2, a locking recess 23 for locking the headrest 30 is formed in the rear wall portion 22. The seat body 20 includes a pair of

side walls

24 and 24 connected to the seat surface portion 21 and the rear wall portion 22 from the side.

Next, the headrest 30 will be explained. The headrest 30 is movable up and down with respect to the seat main body 20 between the position shown in fig. 2 and the position shown in fig. 4. As shown in fig. 1 to 4, the headrest 30 has: a headrest body 31 that opposes the head of a child seated in the child seat 10; a headrest foot portion 35 that extends from the headrest body 31 into the rear wall portion 22 of the seat body 20; and a headrest operating portion 40 that maintains or releases the engagement between the headrest leg portion 35 and the rear wall portion 22.

The headrest body 31 includes: a central wall portion 32 that opposes the rear brain of a child seated in the child seat 10; and a pair of side wall portions 33 extending forward from both end portions of the central wall portion 32 so as to face the lateral brain of the child. A headrest side fixing member 34 for fixing a canopy member 76 described later is fixed to the rear surface of the center wall portion 32.

As shown in fig. 2 to 4, the headrest foot portion 35 includes: a leg body 36 extending downward from a lower end of the central wall portion 32; and a pair of leg engagement portions 37 extending downward from the lower end of the leg body 36. The pair of leg engagement portions 37 are separated from each other in the width direction. Each leg engagement portion 37 includes: a leg extension portion 38 linearly extending downward from the leg main body 36; and a foot protruding portion 39 protruding from the foot extending portion 38 to the inside and outside in the width direction at the lower end portion of the foot extending portion 38. The foot extension 38 has flexibility and can be flexed in the width direction.

The headrest operating portion 40 is disposed so as to face the central wall portion 32 of the headrest body 31 and the rear surface of the leg portion body 36 of the headrest leg portion 35, and extends vertically between the pair of leg portion engagement portions 37 along the leg portion engagement portions 37. The headrest operating portion 40 is disposed so as to be vertically movable with respect to the central wall portion 32 and the leg portion body 36, but the headrest operating portion 40 is biased downward with respect to the central wall portion 32 and the leg portion body 36 by a biasing device, not shown. An operating portion protruding portion 41 that protrudes outward in the width direction is provided at the lower end portion of the headrest operating portion 40 toward each leg engaging portion 37 of the headrest leg portion 35. The operation portion protrusion 41 is provided corresponding to the leg protrusion 39 of the leg engagement portion 37. When the headrest operating portion 40 is not operated, the operating portion protruding portion 41 abuts against the leg protruding portion 39 from the width direction inner side, and the leg extending portion 38 is prevented from being bent to the width direction inner side. On the other hand, when the headrest operating portion 40 is operated and moved upward with respect to the foot engagement portion 37, the operating portion protruding portion 41 is disposed at a position not facing the foot protruding portion 39 when viewed from the width direction, and allows the foot extending portion 38 to flex inward in the width direction.

When the headrest operating portion 40 is not operated in a state where the leg portion protrusion 39 of the headrest leg portion 35 is fitted into the locking recess 23 provided in the rear wall portion 22 of the seat main body 20, the leg portion protrusion 39 cannot be pulled out from the locking recess 23 of the seat main body 20 because the leg portion extending portion 38 of the headrest leg portion 35 cannot be bent inward in the width direction. Therefore, the headrest 30 is maintained in a state of being locked to the seat main body 20. That is, the headrest 30 is prevented from moving relative to the seat main body 20. On the other hand, when the headrest operating portion 40 is operated to allow the leg portion extending portion 38 of the headrest leg portion 35 to flex inward in the width direction, the leg portion protruding portion 39 can be pulled out from the locking recess 23 of the seat main body 20. Therefore, when a force directed upward or downward is applied to the headrest main body 31 and the headrest leg portion 35 in a state where the headrest operation portion 40 is operated, the leg portion extending portion 38 is flexed inward in the width direction (see fig. 3) in accordance with the movement of the leg portion protruding portion 39 with respect to the locking recess 23, and the leg portion protruding portion 39 is pulled out from the locking recess 23. The headrest 30 moves upward or downward with respect to the seat main body 20.

As can be understood from fig. 2 to 4, the plurality of locking recesses 23 of the seat body 20 are provided in the vertical direction. Therefore, when the headrest 30 is moved up and down with respect to the seat main body 20, the headrest 30 can be fixed at an arbitrary height with respect to the seat main body 20 (see fig. 2 and 4).

Next, the canopy device 50 will be explained. As shown in fig. 5 and 6, the canopy device 50 can move up and down with the movement of the headrest 30.

The canopy device 50 includes: a pair of holders 51 fixed to each of the pair of side wall portions 33 of the headrest 30, respectively; and a canopy 60 held by the pair of holders 51.

First, the holder 51 will be described with reference to fig. 7. The pair of

retainers

51, 51 are fixed to the side wall portions 33, 33 of the headrest by bolts, respectively. The holder 51 fixed to the one side wall portion 33 is configured similarly to the holder 51 fixed to the other side wall portion 33. The holder 51 fixed to the one side wall portion 33 will be described below by way of example.

The holder 51 has: a base portion 52 facing the side wall portion 33 of the headrest 30; a front wall portion 53 extending outward in the width direction of the seat body 20 from the front end of the base portion 52; and a protruding portion 54 that protrudes upward and rearward from the front wall portion 53. The protruding portion 54 and the base portion 52 are connected by a connecting portion 55 extending in the width direction. An upper groove portion 56a having the upper surface of the connection portion 55 as a bottom portion and a lower groove portion 56b having the lower surface of the connection portion 55 as a bottom surface are formed between the protruding portion 54 and the base portion 52. These

groove portions

56a and 56b accommodate a part of a canopy base member 61 described later in a state where the canopy 60 is held by the holder 51.

When the headrest 30 is located at the position shown in fig. 2, in other words, when the headrest 30 is disposed at a position where the upper end 30a of the headrest 30 is closest to the upper end 20a of the seat main body 20, the protruding portion 54 is along the edge 24a of the side wall 24 of the seat main body 20. This makes it easy to attach and detach the canopy 60 to and from the holder 51 from the rear of the child seat 10.

Next, the canopy 60 will be explained. As shown more clearly in fig. 2 to 6, the canopy 60 comprises: a pair of canopy base members 61 connected with the holding member 51; a substantially U-shaped canopy rib 75 connected to the canopy base member 61 on the side corresponding to the both end portions; and a canopy member 76 attached to the canopy rib 75.

The canopy base member 61 will be described with reference to fig. 8. The canopy base member 61 connected to the retainer 51 fixed to the one side wall portion 33 of the headrest 30 and the canopy base member 61 connected to the retainer 51 fixed to the other side wall portion 33 of the headrest 30 are configured similarly. The canopy base member 61 connected to the holder 51 fixed to the one side wall portion 33 will be described below by way of example.

The canopy base member 61 has: a first base 62 connected to the holder 51; and a second base 63 pivotally connected to the first base 62.

The first base 62 has: a connecting portion 64 serving as a connecting portion with the holder 51; and a first pivot portion 62a pivotally connected to the second base portion 63. A recess 65 for accommodating the protrusion 54 of the holder 51 is formed on the side of the connecting portion 64 facing the holder 51. The recess 65 extends from the front lower side to the rear upper side. The recess 65 is defined by an inner side wall portion 66 facing the base portion 52 of the holder 51, an outer side wall portion 67 facing the inner side wall portion 66 in the width direction, an upper wall portion 68a connecting upper edges of the inner side wall portion 66 and the outer side wall portion 67, a lower wall portion 68b connecting lower edges of the inner side wall portion 66 and the outer side wall portion 67, and a rear wall portion 69 connecting rear end portions of these

wall portions

66, 67, 68a, 68 b. The protruding portion 54 of the holder 51 can be accommodated from the front of the first base portion 62 by opening the front end portion of the recess 65. The protruding portion 54 accommodated in the recess 65 can be pulled out from the front of the first base portion 62. This allows the canopy 60 to be easily attached and detached from behind the holder 51 (i.e., the bicycle 2). Since the rear end portion of the recess 65 is closed by the rear wall portion 69, the first base portion 62 connected to the holder 51 can be prevented from moving forward and falling off from the holder 51. The inside side wall portion 66 includes: an upper portion 66a extending downward from the upper wall portion 68 a; and a lower portion 66b extending upward from the lower wall portion 68 b. In a state where the first base 62 is connected to the holder 51, the upper portion 66a and the lower portion 66b of the inner side wall portion 66 are respectively received in the upper groove portion 56a and the lower groove portion 56b of the holder 51. This prevents the first base 62 connected to the holder 51 from moving in the width direction and falling off the holder 51.

The first base 62 further has a claw 70 that engages with the holder 51. The claw portion 70 has: an extension portion 71 that extends forward and downward from a rear portion of the lower wall portion 68b of the first base portion 62; and an abutting portion 72 that protrudes upward from the front end of the extending portion 71 and abuts against the front surface of the front wall portion 53 of the holder 51. With such a claw portion 70, the first base portion 62 connected to the holder 51 can be prevented from moving rearward and upward and falling off from the holder 51. The extending portion 71 has flexibility, and by pressing the tip (contact portion 72) of the extending portion 71 downward, the extending portion 71 is flexed, and the engagement between the claw portion 70 and the holder 51 can be released.

The second base 63 has: a second pivot portion 63a pivotally connected to the first pivot portion 62a of the first base portion 62; and a canopy rib holding portion 63b that holds the corresponding end portion of the canopy rib 75. The second pivot portion 63a is rotatable about a rotation axis Ax extending in the width direction with respect to the first base portion 62. The canopy rib holding portion 63b extends from the outer peripheral surface of the second base portion 63 outward in the radial direction of the circle centered on the rotation axis Ax. The canopy rib holding portion 63b has a recess (not shown) extending in the radial direction. The end portion of the canopy rib 75 is accommodated in the recess, whereby the canopy rib 75 is held by the second base 63.

As shown in fig. 9, the canopy frame 75 can be swung with respect to the headrest 30 by rotating the second base 63 with respect to the first base 62.

The canopy rib 75 is formed of metal and/or resin or the like in a substantially narrow plate shape or a line shape. A canopy member 76 is attached to the canopy rib 75.

The canopy member 76 may be formed using a flexible material that can block sunlight. In the illustrated example, the air-permeable sheet is formed of a mesh material in order to ensure air permeability. Of course, the material forming the canopy member 76 is not limited to the mesh material. Various known materials can be used for the canopy member 76. For example, the canopy member 76 may be formed of a resin film material so as to effectively shield wind, rain, and/or dust. Further, the fabric may be made of a water-repellent and/or water-repellent fabric.

In the example shown in fig. 5 and 6, the canopy member 76 is attached to the canopy rib 75 at the front end edge 76a thereof. Further, a canopy side fixing member 77 is provided at the rear end edge 76b of the canopy member 76. The rear end edge 76b is detachably fixed to a headrest side anchor 34 provided on the headrest 30 by a roof side anchor 77. Since the rear end edge 76b of the canopy member 76 is fixed to the rear surface of the headrest 30 and the front end edge 76a of the canopy member 76 is attached to the canopy rib 75, the canopy member 76 is unfolded or folded as the canopy rib 75 swings with respect to the headrest 30. As the canopy side anchor 77 and the headrest side anchor 34, various anchors can be used, and for example, a set of snap fasteners, a hook and loop fastener, or the like can be used.

In order to prevent the canopy member 76 from collapsing in a state where the canopy member 76 is deployed, a flexible auxiliary core bar 78 is built into the canopy member 76. The auxiliary core bar 78 is different from the canopy rib 75 in that it is not connected to the canopy base member 61.

The seating space of the child seat 10 is defined by the seat surface portion 21 of the seat main body 20, the pair of side wall portions 24, and the canopy device 50 attached to the headrest 30. As described above, the canopy device 50 is fixed to the headrest 30 that can move up and down with respect to the seat main body 20. Therefore, the seating space of the child seat 10 is expanded or reduced as the headrest 30 moves relative to the seat main body 20. That is, when the headrest 30 is moved upward relative to the seat main body 20, the seating space can be enlarged. On the other hand, if the headrest 30 is moved downward with respect to the seat main body 20, the seating space can be reduced. Therefore, children of various heights can be covered appropriately even without using a large-sized canopy. That is, the canopy 60 can be downsized. Further, by moving the headrest 30 downward with respect to the seat main body 20, the vertical dimension of the child seat 10 having an enlarged seating space can be reduced.

Further, by detaching the canopy 60 from the holder 51 and the headrest side anchor 34, the vertical dimension of the child seat 10 can be further reduced. In the illustrated example, in particular, the protrusion 54 extending rearward and upward of the holder 51 is received in the recess 65 of the canopy base 61, and the canopy 60 is held by the holder 51. Thus, the canopy 60 is easily attached and detached from the rear of the bicycle 2. This is advantageous in particular in the case where the child seat 10 is a rear child seat fixed to the rear portion of the bicycle 2.

In the above example, the child seat to which the canopy device 50 is attached is the rear child seat 10 attached to the rear portion of the bicycle 2, but is not limited thereto. The child seat to which the canopy device 50 is mounted may also be a front child seat 100 mounted to a front portion of the bicycle 2. That is, the canopy device 50 may be attached to the headrest 130 of the front child seat 100. In this case, the seating space of the front child seat 100 can be enlarged or reduced by moving the headrest 130 up and down with respect to the seat main body 120 of the front child seat 100. Further, by moving the headrest 130 downward with respect to the seat main body 120, the vertical dimension of the child seat having an enlarged seating space can be reduced.

Further, the canopy base member 61, the canopy rib 75, and the holder 51 constitute a supporting device 80 that supports the canopy member 76. In the illustrated example, the support device 80 includes: a holder 51 fixed to the side wall portion 33 of the headrest 30; and a support structure 81 held by the holder 51. The support structure 81 includes the canopy base member 61 and the canopy rib 75. In the illustrated example, the supporting device 80 supports the canopy member 76, but is not limited thereto. For example, the support device 80 may be a member that supports a rain cover covering the seat main body 20. In this case, the seating space defined by the seat main body 20 and the rain cover can be enlarged and reduced by moving the headrest 30 up and down with respect to the seat main body 20. Further, by moving the headrest 30 downward with respect to the seat main body 20, the vertical dimension of the child seat 10 having an enlarged seating space can be reduced.

As described above, according to the present embodiment, the child seat 10 for a bicycle includes: a seat main body 20; a headrest 30 that can move up and down with respect to the seat main body 20; and a canopy device 50 mounted to the headrest 30. According to the child seat 10 with the canopy device 50 for a bicycle, the seating space of the child seat 10 defined by the canopy device 50 and the seat main body 20 can be enlarged and reduced by moving the headrest 30 up and down. Therefore, the canopy 60 can be miniaturized. Further, the size of the child seat 10 for a bicycle, in which the seating space is enlarged, can be reduced by simply moving the headrest 30 downward with respect to the seat main body 20.

Further, according to the present embodiment, the canopy device 50 includes: a holder 51 fixed to the side wall portion 33 of the headrest 30; and a canopy 60 held by the holder 51, the holder 51 having a projection 54 projecting toward the upper rear, the canopy 60 having a recess 65 accommodating the projection 54. Such a child seat 10 for a bicycle makes it easy to attach and detach the canopy 60 from behind the child seat 10 for a bicycle. This is advantageous in particular in the case where the child seat 10 is a rear child seat fixed to the rear portion of the bicycle 2.

Alternatively, according to the present embodiment, the child seat 10 for a bicycle includes: a seat main body 20; a headrest 30 that can move up and down with respect to the seat main body 20; and a support device 80 mounted on the headrest 30. According to the child seat 10 with the supporting device 80 for a bicycle, the seating space of the child seat 10 defined by the supporting device 80 and the seat main body 20 can be enlarged or reduced only by moving the headrest 30 up and down. Therefore, the support device 80 can be miniaturized. Further, the size of the child seat for bicycle 10, in which the seating space is expanded, can be reduced only by moving the headrest 30 downward with respect to the seat main body 20.

In addition, according to the present embodiment, the supporting device 80 includes: a holder 51 fixed to the side wall portion 33 of the headrest 30; and a support structure 81 held by the holder 51, the holder 51 having a protruding portion 54 protruding upward and rearward, the support structure 81 having a recess 65 accommodating the protruding portion 54. Such a child seat for a bicycle 10 makes it easy to attach and detach the support structure 81 from the rear of the child seat for a bicycle 10. This is advantageous in particular in the case where the child seat 10 is a rear child seat fixed to the rear portion of the bicycle 2.

Further, according to the present embodiment, when the headrest 30 is disposed at the position where the upper end portion 30a of the headrest 30 is closest to the upper end portion 20a of the seat main body 20, the protruding portion 54 is along the edge portion 24a of the side wall portion 24 of the seat main body 20. According to the child seat 10 for a bicycle described above, the canopy 60 and the support structure 81 can be easily attached to and detached from the holder 51 from behind the child seat 10.

While several modifications of the above embodiment have been described above, it is needless to say that a plurality of modifications may be appropriately combined and used.
