A rail 15C that slides the slide unit 14 on the back of the central portion,
A lock mechanism 17 that permits or prohibits the rail 15C from sliding on the slide unit 14 is provided below the front surface portion 15A.

Since the structure other than the slide unit 14, the lock groove 13, the rail 15C, and the lock mechanism 17 is basically not significantly different from the seat body on which the conventional bicycle front child is placed, these slide units will be described below. 14, the lock groove 13, the rail 15C, and the lock mechanism 17 will be described in detail.
As shown in FIGS. 1 to 5, the slide unit 14 is a sliding mechanism (sliding mechanism) that slides (slides) the rail 15 </ b> C. The slide unit 14 is mainly composed of a sliding roller 14 </ b> A, an inclined portion 14 </ b> B, And a vertical portion 14C extending from the inclined portion 14B. When the sliding roller 14A slides on the rail 15C, the grip bar 160 can be moved up and down together with the front guard 15 with respect to the seat body 110 from the first position to the second position.

As will be described in detail later, when the front guard 15 is slid from the first position (upper end position) to the second position (lower end position) (in the reverse operation, it operates in the reverse order), these slides The unit 14, the lock groove 13, the rail 15C, and the lock mechanism 17 generally operate as follows.
The lock mechanism 17 that locks the front guard 15 from sliding with respect to the seat body 110 in the first position is released, and the root portion 163 of the grip bar 160 engaged with the lock groove 13 is locked. 13 is lifted obliquely upward, and the engagement between the root portion 163 and the lock groove 13 is released.

  After that, the inclined portion 14B provided with an inclination angle so as to be substantially parallel to the rail 15C is brought into contact with the rail 15C, and the front guard 15 that slides due to the rotation of the sliding roller 14A whose position is fixed is rotated. The rail 15C included in the slide slides, and the front guard 15 slides downward. After the front guard 15 slides downward to the second position, the front guard 15 rotates with respect to the seat body 110 until the vertically provided vertical portion 14C and the rail 15C come into contact with each other. The slide is completed. In addition, such an operation | movement and the structure which implement | achieves such an operation | movement are an example, Comprising: This invention is not limited to such an operation | movement and a structure.

The front guard 15 is composed of, for example, a member constituting the front surface side and a member constituting the back surface side, and the rail 15C is provided on the back surface member, and the inclined portion 14B and the vertical portion 14C of the slide unit 14 are connected to the rail. 15C abuts and the sliding roller 14A slides on the rail 15C.
In order to prevent the front guard 15 from easily falling off the seat body 110, an engagement member that engages the rail 15C that is the moving side sliding member and the slide unit 14 that is the stationary side sliding member may be provided. preferable. Furthermore, it is preferable that the rail 15C is provided with a roller holding portion such as a groove or a protrusion corresponding to the width of the sliding roller 14A so that the sliding roller 14A does not deviate from the rail 15C. Further, since the front guard 15 can easily slide while the rail 15C and the inclined portion 14B and the vertical portion 14C of the slide unit 14 are in contact with each other, a substantially cylindrical sliding roller on which the slide unit 14 slides on the rail 15C. It is also preferable to provide a friction reducing member at the contact portion (though having 14A). These engaging members, holding members and friction reducing members are not shown.

  As shown in FIGS. 3C and 3D, the inclined portion 14B of the slide unit 14 is provided so as to have an inclined surface 14S1 that is substantially parallel to the inclined surface 15S when the front guard 15 slides. Yes. The substantially cylindrical sliding roller 14A slightly protrudes from the surface of the inclined surface 14S1, so that the inclined portion 14B and the rail 15C can come into contact with each other, and the sliding roller 14A and the rail 15C can come into contact with each other. .

As shown in FIGS. 3C and 3D, the vertical portion 14C extending from the inclined portion 14B in the slide unit 14 is an inclined surface after the front guard 15 is rotated in the second position. 15S (the inclined surface 15S in the vertical state after rotating in the direction of arrow XX (4) in FIG. 6D) is provided with a vertical surface 14S2.
In the first position, the lock groove 13 for locking the front guard 15 so as not to be lowered is provided in the seat side wall 112 and is provided so as to remove a part of the seat side wall 112, and has an elliptical shape with a narrow opening in a side view. It is formed with a notch. The base portion 163 of the grip bar 160 enters from the opening portion of the lock groove 13 and moves downward to be engaged at an elliptical portion. The front guard 15 is locked so as not to be lowered unless the root portion 163 of the grip bar 160 moves through the opening of the lock groove 13 and the root portion 163 of the grip bar 160 moves upward and is released from the lock groove 13. The

The lock mechanism 17 is provided below the front surface portion 15A of the front guard 15, and is a mechanism that allows or prohibits the rail 15C from sliding on the slide unit 14. Since such a lock mechanism 17 can be realized by applying a known technique, its structure will not be described in detail.
For example, although not limited, as shown in FIG. 1A, when the lever 17A of the lock mechanism 17 is in a state indicated by a solid line, the rail 15C is prohibited from sliding on the slide unit 14 (slide In the locked state), when the lever 17A is pulled up at a substantially right angle from the state indicated by the solid line to the state indicated by the dotted line, the rail 15C is allowed to slide on the slide unit 14 (slide unlocked state).

  When the lever 17A is not pulled up to the state indicated by the dotted line, the lever 17A naturally returns to the state indicated by the solid line (due to the elastic force of the spring or the like) and enters the slide lock state. It is also preferable to do so. In addition, once the lever 17A of the lock mechanism 17 is pulled up to move from the slide lock state to the slide unlock state, the slide unlock state may be maintained even if the pull-up force stops working. .

・ Front guard 15
Since the front guard 15 basically has a configuration that is not provided for a conventional bicycle front child ride, all the structures of the front guard 15 will be described in detail below.
As described above, the front guard 15 is a plate-like member that shields the lower body of the child seated on the seat portion 120 from the outside, and the left and right ends of the grip bar 160 on the upper end side of the front guard 15 respectively. The rail 15C is connected to the guard 15 and further, on the rear surface of the central portion of the front guard 15, is a rail 15C corresponding to the position from the upper end side position to the lower end side position, on which the slide roller 14A of the slide unit 14 described above slides. Is provided. Note that the root portion 163 that is in the vicinity of the connecting portion between the left and right ends of the grip bar 160 and the front guard 15 engages with the lock groove 13 as described above.

  The front guard 15 includes a front surface portion 15A and left and right portions 15B. The front surface portion 15A and the left and right portions 15B are connected by curved curved surfaces, and the front surface portion 15A and the left and right portions 15B are configured integrally. Yes. The plane constituting the front surface portion 15A and the plane constituting the left and right portions 15B intersect at a maximum of approximately 90 degrees. That is, the left and right portions 15B are extended by bending approximately 90 degrees with respect to the front surface portion 15A. The left and right ends of the grip bar 160 are connected to the left and right portions 15B of the front guard 15 on the upper end side of the left and right portions 15B of the front guard 15, respectively. The rail 15C is provided in a range corresponding to the position from the upper end side (see FIG. 6A) to the lower end side position of the grip bar 160 (see FIG. 6D).

  In the present embodiment, the shape of the rail 15C is a substantially linear shape (it can be said to be a substantially planar shape because it is constituted by the inclined surface 15S), but is not limited to such a shape. When the slide unit 14 slides on the rail 15C, the front guard 15 moves from the upper end side position of the grip bar 160 (see FIG. 6A) to the lower end side position of the grip bar 160 (see FIG. 6D). The rail 15C may have any shape as long as it is attached to the seat body 110 so as to be movable up and down.

  The lock mechanism 17 realizes the slide unlock state only when the lever 17A of the lock mechanism 17 is pulled up by the driver of the bicycle 1000 (or maintains the slide unlock state once lifted), and The lock groove 13 engages the base portion 163 of the grip bar 160 at the first position and locks the front guard 15 so as not to be lowered. Therefore, simply moving the lever 17A of the lock mechanism 17 by the driver of the bicycle 1000 can maintain the locked state in which the front guard 15 moves relative to the seat body 110. In order to release such a state, the base portion 163 of the grip bar 160 engaged with the lock groove 13 is lifted obliquely upward from the lock groove 13 so that the base portion 163 and the lock groove 13 are engaged. (The lock mechanism 17 is operated to shift from the slide lock state to the slide unlock state, and the front guard 15 is lifted obliquely upward so that the root portion 163 of the grip bar 160 is engaged with the lock groove 13. It is necessary to perform two operations of releasing the joint), and sufficient safety can be ensured. On the other hand, at the time of locking, the front guard 15 is locked to the seat body 110 simply by engaging the base portion 163 of the grip bar 160 with the locking groove 13, so that the operability at the time of locking is favorable.

In this case, the inclined portion 14B (inclined surface 14S1) of the slide unit 14 and the rail 15C (inclined surface 15S) of the front guard 15 are in contact with each other.

  Since the base portion 163 of the grip bar 160 is not opened from the lock groove 13 only by pulling the front guard 15 obliquely upward (in the direction of arrow XX (1)), as shown in FIG. Pulling upward (position where the grip bar 160 is located) diagonally forward (in the direction of arrow XX (2)), the base 163 of the grip bar 160 is moved out of the lock groove 13, and the grip bar 160 The root portion 163 is opened. As a result, the lock is released and the front guard 15 can slide with respect to the seat body 110.

As shown in FIG. 6C, the unlocked front guard 15 is further moved (in the direction of arrow XX (3)). At this time, the slide roller 14A of the slide unit 14 is moved by the front guard 15
Since the rail 15C is slid, the front guard 15 moves smoothly. At this time, while the inclined portion 14B (inclined surface 14S1) of the slide unit 14 and the rail 15C (inclined surface 15S) of the front guard 15 abut, the sliding roller 14A slides on the rail 15C and the front guard 15 moves. To do. For example, when the bicycle 1000 is stopped at the bicycle parking lot and the front space of the bicycle 1000 is small, the front guard 15 may be moved in the direction of the arrow XX (3) as described above. Even if it is small, children can be easily put on and off.

  As shown in FIG. 6D, the front guard 15 is further moved downward (arrow XX (3) direction) to the second position. When the front guard 15 moves to the second position, the front guard 15 rotates in the direction of arrow XX (4) with respect to the seat body 110, and the vertically provided vertical portion 14C and the rail 15C come into contact with each other. Then, the slide of the front guard 15 is stopped. At this time, the vertical portion 14C (vertical surface 14S2) of the slide unit 14 and the rail 15C (inclined surface 15S) of the front guard 15 come into contact with each other, and the front guard 15 is held in a substantially vertical direction. Also in this case, when the front space of the bicycle 1000 is small, the front guard 15 may be rotated in this way, so that even if the front space of the bicycle 1000 is small, the child can be easily put on and off. it can.

  Then, the child's seat belt is opened, the driver in the front space of the bicycle 1000 lifts the child sitting on the seat 120, and lifts upward so that the child's leg is not caught by the grip bar 160 retracted downward. In this state, the child is moved in the left-right direction of the bicycle 1000 from the side wall opening 114 provided in the seat side wall 112, or the child is moved in the forward direction of the bicycle 1000 in that state, and the driver moves the bicycle 1000. Leave the child down to the ground.

  In this case, since the grip bar 160 is lowered to the vicinity of the upper surface of the child's thigh, it is not necessary to hold the child and lift it upward in order to avoid the grip bar 160. That is, in the conventional bicycle front child ride, there is a fixed grip bar in front of the abdomen of the seated child, so when lowering the child from the bicycle front child ride, the front space of the bicycle According to this embodiment, the driver 10 lifts the child sitting on the seat and lifts the child's leg up to an upper position at least so as not to be caught by the grip bar. There is no need to lift it up.

[Function and effect]
As described above, according to the bicycle front child ride according to the present embodiment, the grip bar moves up and down. Therefore, when the child is on the child, the finger is placed at the upper end side position, which is the first position. The grip bar can be gripped and when the child is put down, the grip bar does not get in the way when the child is put down at the lower end position, which is the second position.

A lock female portion 130 of a lock mechanism that fixes the grip bar 160 to the seat body 110 when the grip bar 160 is raised to the first position (upper end position);
Is provided.

Since the structure other than the sliding member 140 and the lock female portion 130 is basically not significantly different from the conventional seat body on which the bicycle front child rests, the following description will be given below. Will be described in detail.
As shown in FIG. 10, the sliding member 140 includes a multi-stage cylindrical convex portion 142 (through the hole 142 </ b> H) that protrudes to a position near the toes of the seat body 110, and a middle cylindrical portion of the convex portion 142. (Ball) bearing 144 attached to the front guard 150, and a fitting member 146 that has a diameter larger than the width of the slide groove 156 provided in the front guard 150 and holds the bearing 144 by fitting into the most distal cylindrical portion of the convex portion 142 It consists of and. Here, the sliding member 140 (bearing 144) is provided outside the seat side wall 112, but may be provided inside the seat side wall 112.

  The size of the bearing 144 is such that the inner diameter of the bearing 144 corresponds to the middle cylindrical portion of the convex portion 142 (the inner diameter of the bearing 144 is slightly larger), and the outer diameter of the bearing 144 is the width of the slide groove 156. Corresponding size (the outer diameter of the bearing 144 is slightly smaller). Here, by adjusting the clearance between the outer diameter of the bearing 144 and the width of the slide groove 156, the front guard 150 is put in hand from the state shown in FIG. 13 (B) to the state shown in FIG. 13 (D). It is also preferable that the front guard 150 is slowly and automatically lowered after the lock mechanism is released.

Further, in the seat main body 110, the lock female member 130 of the lock mechanism corresponds to the lock male member 170 provided on the front guard 150 when the grip bar 160 is raised to the first position (upper end position). (One on each side).
As shown in FIG. 12, the lock female member 130 has a hollow, substantially quadrangular prism shape, and the hollow portion forms a through hole 138 into which a lock male member 170 described later enters obliquely downward. More specifically, the seat body side surface 132 and the outer surface 136 opposite to the seat body side surface 132 are provided, and the upper side of the outer surface 136 is provided with a semicircular cutout portion 134 corresponding to the external shape of the push button portion 174 of the lock male member 170.

Then, the lock male member 170 advances obliquely downward toward the lock female member 130, the claw portion 178 of the lock male member 170 enters the through hole 138 of the lock female member 130, and the lock male member 170 is formed on the outer surface 136 of the lock female member 130. The front guard 150 is locked to the seat body 110 by the engagement of the claw portions 178.
As will be described later, when the engagement between the outer surface 136 of the lock female member 130 and the claw portion 178 of the lock male member 170 is released, the lock between the seat body 110 and the front guard 150 is released, and the claw of the lock male member 170 is released. The part 178 is detached from the through hole 138 of the lock female member 130, and the lock male member 170 is retracted obliquely upward from the direction of the lock female member 130, whereby the front guard 150 can be detached from the seat body 110, and the front guard 150 moves downward. By doing so, the grip bar 160 can be moved to the second position (lower end side position).

・ Front guard 150
Since the front guard 150 basically has a configuration that is not provided for a conventional bicycle front child ride, all the structures of the front guard 150 will be described in detail below.
As described above, the front guard 150 is a plate-like member that shields the lower body of the child seated on the seat 120 from the outside, and the left and right ends of the grip bar 160 on the upper end side of the front guard 150 respectively Further, slide grooves 156 corresponding to the position from the upper end side position to the lower end side position, which the bearing 144 of the above-described sliding member 140 slides, are connected to the guard 150. Is provided.

  The front guard 150 includes a front surface portion 152 and a left and right portion 154. The front surface portion 152 and the left and right portion 154 are connected by a curved surface, and the front surface portion 152 and the left and right portion 154 are integrally configured. Yes. The plane that forms the front surface portion 152 and the plane that forms the left and right portions 154 intersect at a maximum of approximately 90 degrees. That is, the left and right portions 154 are extended by bending approximately 90 degrees with respect to the front surface portion 152. The left and right ends of the grip bar 160 are connected to the left and right portions 154 of the front guard 150 on the upper end side of the left and right portions 154 of the front guard 150, respectively. A slide groove 156 is provided in a range corresponding to the position from the upper end side (see FIG. 13A) to the lower end side position of the grip bar 160 (see FIG. 13D).

  In the present embodiment, the shape of the slide groove 156 is curved but substantially linear. However, the shape is not limited to such a shape, and the slide member 140 slides on the slide groove 156. By moving, the front guard 150 can move up and down with respect to the seat body 110 from the upper end side position of the grip bar 160 (see FIG. 13A) to the lower end side position of the grip bar 160 (see FIG. 13D). As long as it is attached to the slide groove 156, the slide groove 156 may have any shape.

  Further, the front guard 150 is provided with a lock male member 170 corresponding to the lock female member 130 of the lock mechanism described above on the seat body 110 when the grip bar 160 is raised to the first position (upper end side position). It is provided at a position corresponding to the lock knife member 130. One lock male portion 170 is provided on each of the left and right sides of the upper ends of the left and right portions 154 of the front guard 150 so as to correspond to the number of lock female portions 130 provided on the left and right.

  As shown in FIG. 12, the lock male part 170 has a main body part 172 for connecting the lock male part 170 to the upper ends of the left and right parts 154 of the front guard 150, and a quadrilateral shape provided at the tip of the lock male part 170. A claw portion 178, a connecting portion 176 that connects the claw portion 178 and the main body portion 172, and a circular push button portion 174 provided in the connecting portion 176 between the claw portion 178 and the main body portion 172. Is done. And the push button part 174, the connection part 176, and the nail | claw part 178 are cut with respect to the main-body part 172 in the three directions (three sides). By pushing the push button portion 174 in the direction indicated by the arrow P, the claw portion 178 is deformed in the direction indicated by the arrow P, and by releasing the push button portion 174 being pushed in the direction indicated by the arrow P, the claw portion 178 returns to its original shape. The lock male member 170 is made of a synthetic resin or the like that is flexible enough to return to (deform in the direction opposite to the arrow P direction).

  Then, the lock male member 170 advances obliquely downward toward the lock female member 130, the claw portion 178 of the lock male member 170 enters the through hole 138 of the lock female member 130, and the lock male member 170 is formed on the outer surface 136 of the lock female member 130. The claw portion 178 contacts and is pressed (without pressing the push button portion 174), the claw portion 178 is deformed in the direction indicated by the arrow P, and the claw portion 178 of the lock male member 170 is moved to the through hole 138 of the lock female member 130. Further, the front guard 150 is locked to the seat body 110 when the claw portion 178 of the lock male member 170 is engaged with the outer side surface 136 of the lock female member 130.

  As described above, when the push button portion 174 is pushed in the arrow P direction, the claw portion 178 is deformed in the arrow P direction, and the outer surface 136 of the lock female member 130 and the claw portion 178 of the lock male member 170 are engaged. By releasing the lock, the seat body 110 and the front guard 150 are unlocked. In this state, when the lock male member 170 is retracted obliquely upward from the direction of the lock female member 130, the claw portion 178 of the lock male member 170 is detached from the through hole 138 of the lock female member 130, and the front guard 150 is detached from the seat body 110. The grip bar 160 can be moved to the second position (lower end side position) by moving the front guard 150 downward.

  As described above, the lock mechanism (the lock female member 130 and the lock male member 170) not only allows the claw portion 178 of the lock male member 170 to enter the through hole 138 of the lock female member 130 but also the outer surface 136 of the lock female member 130 and the lock male member. The claw portion 178 of the 170 engages to lock the movement of the front guard 150 relative to the seat body 110. For this reason, the movement of the front guard 150 relative to the seat body 110 is kept locked simply by releasing the engagement between the outer surface 136 of the lock female member 130 and the claw portion 178 of the lock male member 170. it can. In order to release such a state, the lock male member 170 retracts diagonally upward from the direction of the lock female member 130 in a state where the engagement between the outer surface 136 of the lock female member 130 and the claw portion 178 of the lock male member 170 is released. There is a need (it is necessary to perform two operations of pushing the push button part 174 and raising the front guard 150 obliquely upward), and sufficient safety can be ensured. On the other hand, at the time of locking, the front guard 150 is locked to the seat body 110 only by allowing the claw portion 178 of the lock male member 170 to enter the through hole 138 of the lock female member 130 (without pressing the push button portion 174). The operability at the time is preferable.

[how to use]
A method of using the bicycle front child rest 100 according to the present embodiment having the above-described structure will be described with reference to FIGS. 7 to 13 (mainly FIGS. 7, 8, and 13). In the following, a case will be described in which a child is riding on the bicycle front child ride 100 and the child is lowered from the bicycle front child ride 100. In addition, when the child is not on the bicycle front child ride 100 and the child is put on the bicycle front child ride 100, the procedure is the same except that the procedure is reversed.

  In the state shown in FIG. 13 (A), when the child on the bicycle front child rest 100 is lowered, the driver of the bicycle 1000 wraps around the front side of the bicycle 1000 (the front side of the bicycle front child rest 100), The push button part 174 of the lock male member 170 of the lock mechanism is pushed to raise the front guard 150 obliquely upward (in the direction of arrow X (1)). In this case, the bearing 144 of the sliding member 140 is in contact with the lowermost end portion of the slide groove 156 of the front guard 150.

  As shown in FIGS. 13B and 13C, the unlocked front guard 150 is further moved (arrow X (2) direction and arrow X (3) direction). At this time, since the bearing 144 of the sliding member 140 slides on the slide groove 156 of the front guard 150, the front guard 150 moves smoothly. For example, when the bicycle 1000 is stopped at the bicycle parking lot and the front space of the bicycle 1000 is small, the front guard 150 may be moved in the direction indicated by the arrow X (3) as described above. Even if it is small, children can be easily put on and off.

As shown in FIG. 13D, the front guard 150 is further moved until the bearing 144 of the sliding member 140 comes into contact with the uppermost end portion of the slide groove 156 of the front guard 150. When the bearing 144 of the sliding member 140 comes into contact with the uppermost end portion of the slide groove 156 of the front guard 150, the front guard 150 can freely rotate in the arrow R direction with respect to the seat body 110. Also in this case, when the front space of the bicycle 1000 is small, the front guard 150 may be rotated from the arrow R (2) direction to the arrow R (1) direction in this way. Even if the front space is small, the child can be easily put on and off.

  Then, the child's seat belt is opened, the driver in the front space of the bicycle 1000 lifts the child sitting on the seat 120, and lifts upward so that the child's leg is not caught by the grip bar 160 retracted downward. In this state, the child is moved in the left-right direction of the bicycle 1000 from the side wall opening 114 provided in the seat side wall 112, or the child is moved in the forward direction of the bicycle 1000 in that state, and the driver moves the bicycle 1000. Leave the child down to the ground.

  In this case, since the grip bar 160 is lowered to the vicinity of the child's feet, it is not necessary to hold the child and lift it upward in order to avoid the grip bar 160. That is, in the conventional bicycle front child ride, there is a fixed grip bar in front of the abdomen of the seated child, so when lowering the child from the bicycle front child ride, the front space of the bicycle The driver had to pick up the child sitting on the seat and lift the child's leg at least upward so that it would not be caught on the grip bar, but according to the bicycle front child ride 100 according to the present embodiment, There is no need to lift it up.

[Function and effect]
As described above, according to the bicycle front child ride according to the present embodiment, the grip bar moves up and down. Therefore, when the child is on the child, the finger is placed at the upper end side position, which is the first position. The grip bar can be gripped and when the child is put down, the grip bar does not get in the way when the child is put down at the lower end position, which is the second position.

<Modification>
Below, the 1st modification-4th modification about two embodiment mentioned above is demonstrated. In these modified examples, the grip bar 160 is projected on the same vertical plane in the first area A (1), which is described with reference to FIGS. 6 and 13, and the upper half of the backrest 122 is projected onto the vertical plane. From the first position where the second region A (2) overlaps (the position of the grip bar 160 shown in FIGS. 6A and 13A) to the first region A (1), the second region A The point that the grip bar 160 is movably attached to the seat body 110 to the second position where the position (2) does not overlap (the position of the grip bar 160 shown in FIGS. 6D and 13D). Thus, this embodiment is common to the above-described embodiment.

  In the first modification shown below, the grip bar 160 slides on the two left and right slide grooves 156 from the first position to the second position in the second embodiment described above with respect to the seat body 110. Although the moving member 140 is slid and attached so as to be movable in the vertical direction, the grip bar 160 is attached to the seat main body 110 so as to be movable in the vertical direction with a structure that is not the two left and right slide grooves 156. The second embodiment is different from the second embodiment described above in that it is similar to the first embodiment described above. Furthermore, in the second to fourth modifications, the grip bar 160 is attached to the seat body 110 so as to be movable in the vertical direction from the first position to the second position in the two embodiments described above. However, it differs from the above-described two embodiments in that the grip bar 160 is attached to the seat body 110 so as to be movable in a direction other than the vertical direction. In the following, this point will be mainly described.
