係止部材54は、第1幌基部50が座席本体3に対して取り付けられた状態で座席本体3に対して係止する係止状態(図7(A))と係止を解除する係止解除状態(図7(B))との間を変位可能に設けられる。具体的には、係止部材54は、座席本体3の側部に設けられる挿入孔36(図1(C))に差し込み可能な挿入部55と、第1幌基部50から離れる方向(下方)に延びる延出部材56と、延出部材56から離れる方向(前方)に延び、後述する力伝達部材9の当接部92に押圧される押圧部57とを含む。 The locking member 54 is in a locked state in which it is locked to the seat body 3 when the first hood base 50 is attached to the seat body 3 (FIG. 7(A)), and in a locked state in which it is released from the lock. It is provided so as to be movable between the released state (FIG. 7(B)) and the released state (FIG. 7(B)). Specifically, the locking member 54 has an insertion portion 55 that can be inserted into the insertion hole 36 (FIG. 1(C)) provided on the side of the seat body 3, and a direction away from the first hood base 50 (downward). and a pressing portion 57 that extends in a direction away from the extending member 56 (forward) and is pressed against a contact portion 92 of a force transmitting member 9, which will be described later.

挿入部55は、幌基部本体51から下方に向かって突出する部材であり、穴部52の下方に位置する。さらに、挿入部55は、上下方向途中位置において、幅方向寸法が狭い段差部55aが設けられている。これにより、図7(B)に示すように、延出部材56が段差部55a側に移動することを可能とする。 The insertion portion 55 is a member that projects downward from the hood base main body 51 and is located below the hole portion 52. Further, the insertion portion 55 is provided with a stepped portion 55a having a narrow widthwise dimension at an intermediate position in the vertical direction. This allows the extending member 56 to move toward the stepped portion 55a, as shown in FIG. 7(B).

延出部材56は、挿入部55の延在方向に沿って平行に延びている。延出部材56は、幌基部本体51から下方に延びる棒状部材である。そのため、延出部材56は、延出部材56の起点C(図7)を支点として撓み変形する。起点Cは、幌基部本体51の下端と延出部材56の上端とが交わる交点である。延出部材56の下端部は、フック形状のフック部56aとなっている。図7(A)に示すように、フック部56aは、座席本体3に設けられる挿入孔36の爪部36aと係合する。延出部材56のフック部56aが挿入孔36の爪部36aと係合することで、幌4は座席本体3に取り付けられて保持される。延出部材56のうち、少なくともフック部56aは挿入穴36内に位置する。 The extending member 56 extends parallel to the direction in which the insertion portion 55 extends. The extending member 56 is a rod-shaped member extending downward from the hood base main body 51. Therefore, the extending member 56 bends and deforms using the starting point C (FIG. 7) of the extending member 56 as a fulcrum. The starting point C is an intersection point where the lower end of the hood base main body 51 and the upper end of the extending member 56 intersect. The lower end portion of the extending member 56 is a hook-shaped hook portion 56a. As shown in FIG. 7(A), the hook portion 56a engages with the claw portion 36a of the insertion hole 36 provided in the seat body 3. As shown in FIG. The hook portion 56a of the extending member 56 engages with the claw portion 36a of the insertion hole 36, so that the canopy 4 is attached to and held on the seat body 3. At least the hook portion 56 a of the extending member 56 is located within the insertion hole 36 .

押圧部57は、延出部材56の延在方向の途中位置に設けられ、延出部材56から分岐するように設けられる。押圧部57は、前方に向かって突出する。具体的には、押圧部57は、略水平方向に延びており、延出部材56と押圧部57とのなす角が略直角になるように設けられる。また、押圧部57の先端は、上方に向かってやや傾斜することが好ましい。押圧部57の厚さは、延出部材56よりも薄い。そのため、延出部材56のように撓み変形することはない。押圧部57は、後述する力伝達部材9の当接部92に当接する。 The pressing portion 57 is provided at an intermediate position in the extending direction of the extending member 56, and is provided so as to branch from the extending member 56. The pressing portion 57 projects forward. Specifically, the pressing portion 57 extends substantially horizontally, and is provided so that the angle formed by the extending member 56 and the pressing portion 57 is approximately a right angle. Further, it is preferable that the tip of the pressing portion 57 be slightly inclined upward. The thickness of the pressing portion 57 is thinner than that of the extending member 56. Therefore, unlike the extension member 56, it does not bend and deform. The pressing portion 57 contacts a contact portion 92 of a force transmitting member 9, which will be described later.

押圧部57は、力伝達部材9の当接部92の変位を延出部材56に伝える部分である。図7(A)に示すように、力伝達部材9の当接部92が押圧部57に当接し、当接部92により押されることで、図7(B)に示すように、延出部材56が延出部材56の起点Cを支点として撓み変形する。つまり、力伝達部材9の操作部91を操作することで、力伝達部材9の当接部92が押圧部57を押して、延出部材56が挿入部55側に移動するため、フック部56aと爪部36aの係合を解除することができる。 The pressing portion 57 is a portion that transmits the displacement of the contact portion 92 of the force transmitting member 9 to the extending member 56. As shown in FIG. 7(A), the contact portion 92 of the force transmission member 9 contacts the pressing portion 57 and is pushed by the contact portion 92, so that the extending member 56 is bent and deformed using the starting point C of the extending member 56 as a fulcrum. That is, by operating the operation part 91 of the force transmission member 9, the contact part 92 of the force transmission member 9 pushes the pressing part 57, and the extension member 56 moves toward the insertion part 55, so that the hook part 56a and The engagement of the claw portion 36a can be released.

(持ち手について)
図4および図5を参照して、持ち手8について説明する。持ち手8は、幌4を着脱する際に、使用者が手で掴む部分であり、第1幌基部50に固定されている。
(About the handle)
The handle 8 will be explained with reference to FIGS. 4 and 5. The handle 8 is a part that is held by the user's hand when attaching and detaching the top 4, and is fixed to the first top base 50.

持ち手8は、持ち手本体80と、持ち手本体80から第1幌基部50に向かって幅方向に突出する固定軸82とを含む。持ち手本体80は、正面視において上下に細長い矩形形状であり、角部が面取りされている。持ち手本体80は、幅方向に厚みを有する。これにより、持ち手本体80は、片手で持ちやすくなるように設計されている。なお、持ち手本体80は、片手で持ちやすければよく、たとえば側面視において円形状などであってもよい。 The handle 8 includes a handle main body 80 and a fixed shaft 82 that protrudes from the handle main body 80 toward the first hood base 50 in the width direction. The handle main body 80 has a vertically elongated rectangular shape when viewed from the front, and has chamfered corners. The handle main body 80 has a thickness in the width direction. Thereby, the handle main body 80 is designed to be easy to hold with one hand. Note that the handle main body 80 only needs to be easy to hold with one hand, and may have a circular shape when viewed from the side, for example.

特に図5に示すように、固定軸82には、凸部82aが設けられている。固定軸82は、後述する力伝達部材9の貫通孔93を貫通し、第1幌基部50の穴部52に固定される。固定軸82の凸部82aは、穴部52の凹部52aに嵌合する。そのため、持ち手8は、第1幌基部50に固定されて、第1幌基部50に対して回転しない。図3(A)に示すように、持ち手8は、たとえば係止部材54の挿入部55の延在方向と同方向に傾斜した状態で、第1幌基部50に固定される。 In particular, as shown in FIG. 5, the fixed shaft 82 is provided with a convex portion 82a. The fixed shaft 82 passes through a through hole 93 of the force transmitting member 9, which will be described later, and is fixed to the hole 52 of the first hood base 50. The protrusion 82a of the fixed shaft 82 fits into the recess 52a of the hole 52. Therefore, the handle 8 is fixed to the first hood base 50 and does not rotate relative to the first hood base 50. As shown in FIG. 3(A), the handle 8 is fixed to the first hood base 50 while being inclined in the same direction as the extending direction of the insertion portion 55 of the locking member 54, for example.

(力伝達部材について)
図4および図5を参照して、力伝達部材9について説明する。力伝達部材9は、第1幌基部50および持ち手8に対して変位可能に設けられる部分である。力伝達部材9は、第1幌基部50と持ち手8との間に設けられる。
(About force transmission members)
The force transmission member 9 will be described with reference to FIGS. 4 and 5. The force transmitting member 9 is a portion that is displaceably provided with respect to the first hood base 50 and the handle 8. The force transmission member 9 is provided between the first hood base 50 and the handle 8.

力伝達部材9は、力伝達本体部90と、力伝達本体部90を操作する操作部91と、力伝達本体部90から第1幌基部50に向かって突出する当接部92と、力伝達本体部90を貫通する貫通孔93とを含む。 The force transmitting member 9 includes a force transmitting main body 90, an operating section 91 for operating the force transmitting main body 90, an abutting section 92 protruding from the force transmitting main body 90 toward the first hood base 50, and a force transmitting main body 90. A through hole 93 passing through the main body portion 90 is included.

図4に示すように、操作部91は、力伝達本体部90の前方側に位置し、持ち手8の側壁よりも前方に突出する面を有する。操作部91は、たとえば親指などで押圧可能なレバーである。図6(B)に示すように、操作部91を操作することにより、図7(B)に示すように、係止部材54が係止解除状態となる。 As shown in FIG. 4 , the operating section 91 is located on the front side of the force transmitting main body section 90 and has a surface that projects further forward than the side wall of the handle 8 . The operating portion 91 is a lever that can be pressed with, for example, a thumb. As shown in FIG. 6(B), by operating the operating portion 91, the locking member 54 is brought into the unlocked state as shown in FIG. 7(B).

当接部92は、たとえばピンであり、第1幌基部50の幌基部本体51の下端と係止部材54の押圧部57の上端との間に位置する。具体的には、当接部92は、押圧部57に当接し、操作部91の操作により押圧部57を変位させる。 The contact portion 92 is, for example, a pin, and is located between the lower end of the hood base main body 51 of the first hood base 50 and the upper end of the pressing portion 57 of the locking member 54 . Specifically, the contact portion 92 contacts the pressing portion 57 and displaces the pressing portion 57 by operating the operating portion 91 .

貫通孔93は、操作部91よりも後方側に位置する。貫通孔93は、持ち手8の固定軸82が貫通する。上述のように、持ち手8の固定軸82は、幌基部本体51に設けられる穴部52に固定される。つまり、力伝達部材9は、幌基部5に設けられる軸を支点として回動可能に設けられる。また、力伝達部材9は、延出部材56の撓み変形による弾性力により元の位置に復帰可能に設けられる。具体的には、力伝達部材9の当接部92と押圧部57とが当接しているため、延出部材56が元の位置に戻ろうとする復帰力により、力伝達部材9は、元の位置に戻る。なお、力伝達部材9は、合成樹脂などで形成されているが、たとえばバネなどの付勢部材により、非係合状態に付勢されていてもよい。 The through hole 93 is located on the rear side of the operating section 91. The fixed shaft 82 of the handle 8 passes through the through hole 93 . As described above, the fixed shaft 82 of the handle 8 is fixed to the hole 52 provided in the top base body 51. That is, the force transmitting member 9 is provided so as to be rotatable about the shaft provided on the top base 5 as a fulcrum. Further, the force transmitting member 9 is provided so as to be able to return to its original position by the elastic force caused by the bending deformation of the extending member 56. Specifically, since the contact portion 92 of the force transmission member 9 and the pressing portion 57 are in contact with each other, the force transmission member 9 returns to its original position due to the restoring force that causes the extension member 56 to return to its original position. Return to position. Although the force transmitting member 9 is made of synthetic resin or the like, it may be biased to the non-engaged state by a biasing member such as a spring.

図7(A)に示すように、力伝達部材9の当接部92と係止部材54の押圧部57とが接触する接触点Bと固定軸82の軸Aとの距離L1は、係止部材54の延出部材56の起点Cと固定軸82の軸Aとの距離L2よりも大きくなるように設定されている(L2<L1)。これにより、本実施の形態は、係止部材54の延出部材56の起点C付近を直接押圧するよりも小さい力で係止部材54のフック部56aと挿入孔36の爪部36との係止状態を解除することができる。 As shown in FIG. 7(A), the distance L1 between the contact point B where the contact portion 92 of the force transmitting member 9 and the pressing portion 57 of the locking member 54 and the axis A of the fixed shaft 82 is The distance is set to be greater than the distance L2 between the starting point C of the extending member 56 of the member 54 and the axis A of the fixed shaft 82 (L2<L1). As a result, in this embodiment, the hook portion 56a of the locking member 54 and the claw portion 36 of the insertion hole 36 are engaged with each other with a smaller force than when directly pressing the vicinity of the starting point C of the extension member 56 of the locking member 54. The stopped state can be canceled.

(幌の着脱方法について)
次に、図1、図6、および図7を参照して、座席本体3に対して幌4を着脱する方法について説明する。
(About how to attach and detach the hood)
Next, a method for attaching and detaching the top 4 to and from the seat body 3 will be described with reference to FIGS. 1, 6, and 7.

幌4を座席本体3に装着するには、幌4の両端の持ち手8をそれぞれの手で持ち、座席本体3に設けられる挿入孔36(図1,図7)に第1幌基部50の挿入部55を差し込む。図7(A)に示すように、挿入孔36には、内部に向かって突出する爪部36aが設けられている。第1幌基部50には係止部材54が設けられている。そのため、第1幌基部50の挿入部55を挿入孔36に差し込んでいくと、延出部材56のフック部56aが挿入孔36の爪部36aを乗り越えて、フック部56aと爪部36aが掛かり合う(図7(A))。これにより、幌を簡単に座席本体3に取り付けることができる。 To attach the canopy 4 to the seat body 3, hold the handles 8 at both ends of the canopy 4 with each hand, and insert the first canopy base 50 into the insertion hole 36 (FIGS. 1 and 7) provided in the seat body 3. Insert the insertion part 55. As shown in FIG. 7(A), the insertion hole 36 is provided with a claw portion 36a that projects inward. A locking member 54 is provided on the first hood base 50 . Therefore, when the insertion part 55 of the first hood base 50 is inserted into the insertion hole 36, the hook part 56a of the extending member 56 gets over the claw part 36a of the insertion hole 36, and the hook part 56a and the claw part 36a are engaged. (Figure 7(A)). Thereby, the top can be easily attached to the seat body 3.

なお、幌4を座席本体3に装着する際には、4本の幌骨41~44を閉状態にし、幌4を座席本体3に装着した後に、任意の広さに広げることが好ましい。 Note that when attaching the canopy 4 to the seat body 3, it is preferable to close the four canopy ribs 41 to 44, and after attaching the canopy 4 to the seat body 3, spread it out to an arbitrary width.

幌4を座席本体3から取り外すには、図6(A)で示すように、座席本体3に取り付けられている幌4の一対の持ち手8を両手で持つ。図6(B)で示すように、たとえば持ち手8を親指以外の4本の指で掴み、力伝達部材9の操作部91を親指で押さえる。図7(B)で示すように、力伝達部材9の当接部92が係止部材54の押圧部57を下方に押圧し、係止部材54の延出部材56が起点Cを支点に撓み変形し、挿入部55側に向かって傾斜する。これにより、延出部材56のフック部56aと爪部36aの係止が解除される。この状態で、持ち手8を上方に持ち上げることで、係止部材54の挿入部55を挿入孔36から引き抜き、幌4を座席本体3から取り外すことができる。 To remove the canopy 4 from the seat body 3, as shown in FIG. 6(A), hold the pair of handles 8 of the canopy 4 attached to the seat body 3 with both hands. As shown in FIG. 6(B), for example, the handle 8 is grasped with four fingers other than the thumb, and the operating portion 91 of the force transmission member 9 is pressed with the thumb. As shown in FIG. 7(B), the contact portion 92 of the force transmission member 9 presses the pressing portion 57 of the locking member 54 downward, and the extending member 56 of the locking member 54 is bent about the starting point C. It deforms and tilts toward the insertion portion 55 side. As a result, the engagement between the hook portion 56a of the extending member 56 and the claw portion 36a is released. In this state, by lifting the handle 8 upward, the insertion portion 55 of the locking member 54 can be pulled out from the insertion hole 36, and the canopy 4 can be removed from the seat body 3.

なお、幌4を座席本体3から取り外す際には、4本の幌骨41~44を閉状態にすることが好ましい。 Note that, when the top 4 is removed from the seat body 3, it is preferable that the four top ribs 41 to 44 be in a closed state.

従来の着脱可能に設けられるチャイルドシートの幌は、幌のフックとチャイルドシートのフックとの係合部を直接解除し、これらのフックを非係合に維持した状態で幌を引き抜く必要があり、幌の取り外しにツーアクション必要であり、操作性が悪かった。さらに、係合部を直接解除する際に、指挟みなどの懸念があり、安全性の観点からも好ましくなかった。 With conventional removable child seat tops, it is necessary to directly release the engagement between the hooks of the top and the hooks of the child seat, and then pull out the top while keeping these hooks disengaged. Removal required two actions, and operability was poor. Furthermore, when directly releasing the engaging portion, there is a risk of fingers being caught, which is not preferable from a safety standpoint.

また、他の従来の着脱可能に設けられるチャイルドシートの幌は、幌のフックとチャイルドシートのフックとを解除する際に、幌全体に力が加わってしまい、幌が前方に回動するため、操作性が悪かった。 In addition, with other conventional removable child seat tops, when releasing the hooks on the top and child seat, force is applied to the entire top, causing the top to rotate forward, making it difficult to operate. was bad.

それに対し、本実施の形態の幌4は、持ち手8が設けられ、力伝達部材9の操作部91を操作することで、係止部材54と座席本体3との係止を解除することができる。持ち手8を持った状態で操作部91を操作すれば、幌4の係止部材54の係止を確実に解除することができるため、操作性がよい。また、力伝達部材9は持ち手8に対して変位可能に設けられ、幌骨41,42,43,44にまで力伝達部材9の変位が伝わらないため、操作部91で係止部材54を変位させたとしても幌骨41,42,43,44および幌布45が前方に変位することがなく、この観点からも操作性がよい。 In contrast, the canopy 4 of this embodiment is provided with a handle 8, and the locking member 54 and the seat body 3 can be unlocked by operating the operating portion 91 of the force transmitting member 9. can. By operating the operating portion 91 while holding the handle 8, the locking member 54 of the top 4 can be reliably released, resulting in good operability. In addition, the force transmitting member 9 is provided so as to be displaceable with respect to the handle 8, and the displacement of the force transmitting member 9 is not transmitted to the canopy bones 41, 42, 43, and 44. Even if they are displaced, the hood ribs 41, 42, 43, 44 and the hood cloth 45 will not be displaced forward, and from this point of view as well, the operability is good.

また、操作部91を操作することで係止部材54を変位させるため、従来技術のように係合部を直接解除する必要がないため、指挟みの危険性がなく、安全性にも優れている。さらに、幌4は、幌基部5、持ち手8、および操作部91が設けられる力伝達部材9の3つの部材で形成されるため、簡易な構成とすることができ、部品点数を少なくすることができる。 Furthermore, since the locking member 54 is displaced by operating the operating portion 91, there is no need to directly release the engaging portion as in the prior art, so there is no risk of finger pinching, and the system is highly safe. There is. Furthermore, since the canopy 4 is formed of three members: the canopy base 5, the handle 8, and the force transmitting member 9 in which the operation part 91 is provided, the canopy 4 can have a simple configuration and reduce the number of parts. I can do it.

なお、本実施の形態の幌4は、操作部91が設けられる力伝達部材9は、固定軸82を支点として回動可能に設けられるとしたが、限定的ではなく、たとえば前後方向、幅方向、上下方向など直線的に移動可能であってもよい。 In addition, in the canopy 4 of the present embodiment, the force transmitting member 9 on which the operating part 91 is provided is provided so as to be rotatable about the fixed shaft 82; however, this is not limited to this; , it may be movable linearly, such as in the vertical direction.

また、本実施の形態において、持ち手8と幌基部5とは別の部材で構成したが、同一部材であってもよく、たとえば幌基部5に持ち手8となる凸部などが設けられていてもよい。 Further, in this embodiment, the handle 8 and the hood base 5 are made of separate members, but they may be the same member. For example, the hood base 5 may be provided with a convex portion that becomes the handle 8. It's okay.

本実施の形態の力伝達部材8は、持ち手8に対して回転可能に固定されていたが、持ち手8に対して変位可能に設けられていればよく、たとえば幌基部5に対して軸支されていてもよく、固定される部材については限定されない。 Although the force transmitting member 8 of the present embodiment is rotatably fixed to the handle 8, it may be displaceable relative to the handle 8. It may be supported, and the member to be fixed is not limited.

以上、図面を参照してこの発明の実施の形態を説明したが、この発明は、図示した実施の形態のものに限定されない。図示した実施の形態に対して、この発明と同一の範囲内において、あるいは均等の範囲内において、種々の修正や変形を加えることが可能である。 Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments.
