Description

本願発明は、複数の部材からなり、各部材の位置を変えて形態を変化させることができる形態変化装置に関する。 The present invention relates to a form change device that includes a plurality of members and can change the form by changing the position of each member.

従来の形態変化装置は、複数の部材が支軸、リンク部材等の連結部材により回動可能に連結され、各部材の位置を変えることにより、形態を変化させるものがあった。例えば、初期状態では自動車形態の形態変化装置が、各部材の位置を回動して変えることにより、ロボット形態に変化させることができるようなものである（例えば、特許文献１）。
特開昭６２−１２９０７９号公報 In the conventional form change device, a plurality of members are rotatably connected by connecting members such as a support shaft and a link member, and the form is changed by changing the position of each member. For example, in an initial state, a form change device in the form of an automobile can change the position of each member into a robot form by rotating and changing the position of each member (for example, Patent Document 1).

上記従来の形態変化装置は、各部材同士を係合し、この係合を解除不能にロックするロック手段が設けられていないので、各部材同士が分離しやすいという問題点があった。例えば、形態変化装置は、自動車形状であると横長形状であるので、安定して載置しておくことができるが、自動車形状をロボット形状に形態変化させると縦長形状となるので、安定して載置することができず、倒れやすくなる。形態変化装置は、倒れた場合、各部材が分離してしまうおそれがあるという問題点があった。 The conventional form change device has a problem in that the members are easily separated from each other because the locking means for engaging the members and locking the engagement so as not to be released is not provided. For example, since the shape change device has a horizontally long shape when it is in the shape of an automobile, it can be placed stably. However, if the shape of the vehicle is changed to a robot shape, it becomes a vertically long shape. It cannot be placed and tends to collapse. When the shape change device falls down, there is a problem that each member may be separated.

形態変化装置１は、上記構成を有し、第１の部材１１に対する第２の部材１２の位置に応じて、自動車形態（第１の形態）とロボット形態（第２の形態）に変化させることができる。図１，２に示すように、形態変化装置１は、自動車形態（第１の形態）となってお
り、第１の部材１１の下面２２と第２の部材１２の上面４１が当接し、第１の部材１１の第１の係合面３３と第２の部材１２の第２の係合面９３が係合している。このとき、第２の部材１２の係合部材５０は、弾性部材７７によって係合方向に付勢された状態で、第１の部材１１の係合凹部３０に係合している。第１の連結部材１３及び第２の連結部材１４は、第１の部材１１の後面２４と第２の部材１２の後面４４と略平行となっている。 The form change device 1 has the above-described configuration, and changes the form into an automobile form (first form) and a robot form (second form) according to the position of the second member 12 with respect to the first member 11. Can do. As shown in FIGS. 1 and 2, the form change device 1 is in the form of an automobile (first form), in which the lower surface 22 of the first member 11 and the upper surface 41 of the second member 12 come into contact with each other. The first engagement surface 33 of the first member 11 is engaged with the second engagement surface 93 of the second member 12. At this time, the engaging member 50 of the second member 12 is engaged with the engaging recess 30 of the first member 11 while being urged in the engaging direction by the elastic member 77. The first connecting member 13 and the second connecting member 14 are substantially parallel to the rear surface 24 of the first member 11 and the rear surface 44 of the second member 12.

形態変化装置１は、上記自動車形態（第１の形態）からロボット形態（第２の形態）に変化させることが出来る。形態変化装置１は、第１の部材１１の後面２４側と第２の部材１２の後面４４側を接地させて横長の形にする（すなわち、形態変化装置１の姿勢を重力方向に対して垂直にする）と、ロック部材６５が自重により、傾斜路６３の凹部６６内に入り込んでいる（非当接位置又は非ロック位置にある）ので、ロック部材６５と係合部材５０のガイド縁５４とが当接しないため、係合部材５０を弾性部材７７の弾性に抗して、反係合方向に移動させることができる。図２、図８（ｂ）に示すように、操作部材７０を案内溝７６に沿って移動させると、傾斜面７１が係合部材５０の傾斜縁５３に摺接し、係合部材５０を弾性部材７７の弾性に抗して、反係合方向即ちガイド路６０内に没入する方向に移動させることができる。 The form change device 1 can change from the automobile form (first form) to the robot form (second form). In the shape change device 1, the rear surface 24 side of the first member 11 and the rear surface 44 side of the second member 12 are grounded to form a horizontally long shape (that is, the posture of the shape change device 1 is perpendicular to the direction of gravity. ), The lock member 65 enters the recess 66 of the inclined path 63 by its own weight (in the non-contact position or the non-lock position), so that the lock member 65 and the guide edge 54 of the engagement member 50 Therefore, the engagement member 50 can be moved in the anti-engagement direction against the elasticity of the elastic member 77. As shown in FIGS. 2 and 8B, when the operating member 70 is moved along the guide groove 76, the inclined surface 71 comes into sliding contact with the inclined edge 53 of the engaging member 50, and the engaging member 50 is moved to the elastic member. It can be moved in the anti-engagement direction, that is, the direction of immersing in the guide path 60 against the elasticity of 77.

形態変化装置１は、係合部材５０がガイド路６０内に没入すると、係合部材５０の係合凹部３０に対する係合が解除され、図７に示すように、第１の部材１１を移動させることが出来る。第１の部材１１は、第１の連結部材１３が支軸３８を中心として時計方向に回動し、第２の連結部材１４が支軸３９を中心として時計方向に回動して、第２の部材１２の上方に移動し、後面２４が第２の部材１２の前面４３に当接する。 When the engaging member 50 is immersed in the guide path 60, the shape change device 1 disengages the engaging member 50 from the engaging recess 30 and moves the first member 11 as shown in FIG. I can do it. In the first member 11, the first connecting member 13 rotates clockwise around the support shaft 38, the second connecting member 14 rotates clockwise around the support shaft 39, and the second member The rear surface 24 comes into contact with the front surface 43 of the second member 12.

係止部材８０は、係合凹部８３が係合凸起８９に係合し、弾性部材９０に付勢された状態で案内路８５内に没入しており、係止方向に移動させると、係合凹部８３が係合凸起８９から外れて、第１の部材１１の係止凹部２８内に突出し、図６に示すように、係止凹部２８を係止する。このように、形態変化装置１は、第１の部材１１を第２の部材１２の上に載置させることによって、図５に示すように、ロボット形態（第２の形態）に変化させることができる。 The locking member 80 is immersed in the guide path 85 in a state in which the engagement recess 83 is engaged with the engagement protrusion 89 and is urged by the elastic member 90. The mating recess 83 is disengaged from the engagement protrusion 89 and protrudes into the locking recess 28 of the first member 11 to lock the locking recess 28 as shown in FIG. Thus, the form change device 1 can change the robot form (second form) as shown in FIG. 5 by placing the first member 11 on the second member 12. it can.

形態変化装置１は、ロボット形態（第２の形態）から自動車形態（第１の形態）に変化させるには、係止部材８０の係止を解除しなければならない。係止部材８０は、弾性部材９０の弾性に抗して反係止方向に移動させると、第１の部材１１の係止凹部２８内から引き抜かれて案内路８５内に没入し、係止部材８０の係止凹部２８に対する係止が解除され、係合凹部８３が係合凸起８９に係合して位置決めがされる。 In order to change the form change device 1 from the robot form (second form) to the automobile form (first form), the lock of the locking member 80 must be released. When the locking member 80 is moved in the anti-locking direction against the elasticity of the elastic member 90, the locking member 80 is pulled out from the locking recess 28 of the first member 11 and enters the guide path 85, and the locking member The locking of the 80 with respect to the locking recess 28 is released, and the engagement recess 83 is engaged with the engagement protrusion 89 to be positioned.

図７に示すように、第１の部材１１は、移動させることができ、第１の連結部材１３が支軸３８を中心として反時計方向に回動し、第２の連結部材１４が支軸３９を中心として反時計方向に回動して、第２の部材１２の前方に移動し、下面２２が第２の部材１２の上面４１に当接し、第１の部材１１の第１の係合面３３が第２の部材１２の第２の係合面９３に係合する。第１の係合面３３は、第２の係合面９３に係合する前に、係合部材５０の湾曲部５２と摺接し、係合部材５０を弾性部材７７の弾性に抗して、一旦ガイド路６０内に没入させ、第２の係合面９３に係合すると、弾性部材７７によって係合部材５０が第１の部材１１の係合凹部３０に係合する。 As shown in FIG. 7, the first member 11 can be moved, the first connecting member 13 rotates counterclockwise about the support shaft 38, and the second connecting member 14 is the support shaft. It rotates counterclockwise about 39 and moves to the front of the second member 12, the lower surface 22 abuts on the upper surface 41 of the second member 12, and the first engagement of the first member 11 The surface 33 engages with the second engagement surface 93 of the second member 12. Before the first engagement surface 33 is engaged with the second engagement surface 93, the first engagement surface 33 is in sliding contact with the curved portion 52 of the engagement member 50, and the engagement member 50 is resisted by the elasticity of the elastic member 77. Once immersed in the guide path 60 and engaged with the second engagement surface 93, the engagement member 50 is engaged with the engagement recess 30 of the first member 11 by the elastic member 77.

形態変化装置１は、図３，４に示すように、自動車形態（第１の形態）において、第２の部材１２の下面４２を接地させ、第１の部材１１が第２の部材１２に載った形で縦長とする（すなわち、形態変化装置１の姿勢を重力方向に対して平行にする）と、ロック部材６５は、自重により、傾斜路６３に沿って移動し、係合部材５０のガイド突起５５に当接して係止孔部６７に係止される（当接位置又はロック位置にある）。係合部材５０を弾性
部材７７の弾性に抗して、反係合方向に移動させようとしても、ガイド縁５４がロック部材６５に当接するので、係合部材５０がガイド路６０内に没入することがなく、係合部材５０の係合凹部８３に対する係合が解除されない。なお、図３に示すように、係止部材８０は、下端８８が接地すると、係合凹部８３が係合凸起８９から外れて、案内路８５から突出する。 As shown in FIGS. 3 and 4, the shape change device 1 grounds the lower surface 42 of the second member 12 in the automobile form (first form), and the first member 11 is placed on the second member 12. If the shape change device 1 is vertically long (that is, the posture of the shape change device 1 is parallel to the direction of gravity), the lock member 65 moves along the inclined path 63 by its own weight, and guides the engagement member 50. It abuts on the protrusion 55 and is engaged with the engagement hole 67 (in the contact position or the lock position). Even if the engagement member 50 is moved in the anti-engagement direction against the elasticity of the elastic member 77, the guide edge 54 contacts the lock member 65, so that the engagement member 50 is immersed in the guide path 60. The engagement of the engagement member 50 with respect to the engagement recess 83 is not released. As shown in FIG. 3, when the lower end 88 of the locking member 80 contacts the engaging member 80, the engaging recess 83 is disengaged from the engaging protrusion 89 and protrudes from the guide path 85.

このように、形態変化装置１は、第２の部材１２の上面４１に第１の部材１１の下面２２を接合させて重ねると、第１の部材１１の係合凹部３０に第２の部材１２の係合部材５０が係合する。当該係合部材５０の係合位置において、第２の部材１２を下にして第１の部材１１を載せた縦長の形（すなわち、形態変化装置１の姿勢が重力方向に対して平行となる形）にし、第２の部材１２の下面４２を下方に向けると、ロック部材６５が自重によりロック位置（当接位置、係止孔部６７）に移動して係合部材５０をロックし、第１の部材１１と第２の部材１２の分離を不能にする。このことにより、第２の部材１２を下にして第１の部材１１を載せた縦長とする形にしたときに、何らかの理由で係合凹部３０と係合部材５０の係合が外れて、第１の部材１１が自重により第２の部材１２の上面４１から落下して不意に自動車形態からロボット形態に変化し、第１の部材１１の後面２４と第２の部材１２の前面４３との間、または、第１の部材１１の下面２２と接地面との間で指を挟んで怪我をしてしまう等の危険を防止することができる。 As described above, when the shape changing device 1 joins and overlaps the lower surface 22 of the first member 11 on the upper surface 41 of the second member 12, the second member 12 is placed in the engagement recess 30 of the first member 11. The engaging member 50 is engaged. In the engagement position of the engagement member 50, a vertically long shape in which the first member 11 is placed with the second member 12 facing down (that is, a shape in which the posture of the shape change device 1 is parallel to the gravity direction). ) And the lower surface 42 of the second member 12 is directed downward, the lock member 65 moves to the lock position (abutment position, locking hole 67) by its own weight to lock the engagement member 50, and The separation of the member 11 and the second member 12 is disabled. Thus, when the first member 11 is placed vertically with the second member 12 facing down, the engagement recess 30 and the engagement member 50 are disengaged for some reason. The first member 11 falls from the upper surface 41 of the second member 12 due to its own weight, unexpectedly changes from the automobile form to the robot form, and between the rear surface 24 of the first member 11 and the front surface 43 of the second member 12. Alternatively, it is possible to prevent danger such as injury by pinching a finger between the lower surface 22 of the first member 11 and the ground surface.

また形態変化装置１は、第２の部材１２の下面４２を略水平方向に向けて第１の部材１１と第２の部材１２を横長の形（すなわち、形態変化装置１の姿勢が重力方向に対して垂直となる形）にすると、この場合は係合凹部３０と係合部材５０の係合が外れたとしても、第１の部材１１の重量により不意に自動車形態からロボット形態に変化して怪我をしてしまうようなことはないので、ロック部材６５は自重により非ロック位置（非当接位置、凹部６６）に移動して係合部材５０のロックを解除し、第１の部材１１と第２の部材１２が分離することを可能にする。このように、形態変化装置１は、形態変化装置１の重力方向に対する姿勢に応じて、ロック部材６５が自重によって移動することにより、係合部材５０の係合を解除不能にロックしたり、ロック解除したりすることができる。 In addition, the shape change device 1 has the first member 11 and the second member 12 in a horizontally long shape with the lower surface 42 of the second member 12 oriented in a substantially horizontal direction (that is, the posture of the shape change device 1 is in the direction of gravity. In this case, even if the engagement recess 30 and the engagement member 50 are disengaged, the weight of the first member 11 causes a sudden change from the automobile form to the robot form. Since there is no risk of injury, the lock member 65 moves to the non-lock position (non-contact position, recess 66) due to its own weight, unlocks the engagement member 50, and the first member 11 Allows the second member 12 to separate. In this way, the shape change device 1 locks the engagement of the engagement member 50 so that the engagement of the engagement member 50 cannot be released or the lock by moving the lock member 65 by its own weight according to the posture of the shape change device 1 with respect to the gravity direction. Or cancel it.

上記実施の形態では、ロック部材６５により係合部材５０の係合を解除不能にロックしたり、ロック解除したりしたが、係合部材５０を操作する操作部材７０をロックするようにしても構わない。係る形態変化装置１は、係合部材５０の係合位置において、第２の部材１２を下にして第１の部材１１を載せた縦長の形（すなわち、形態変化装置１の姿勢が重力方向に対して平行となる形）にし、第２の部材１２の下面４２を下方に向けると、ロック部材６５が自重によりロック位置（当接位置、係止孔部６７）に移動して操作部材７０をロックし、係合部材５０の係合を解除できないようにして第１の部材１１と第２の部材１２の分離を不能にする。このことにより、第２の部材１２を下にして第１の部材１１を載せた縦長の形（すなわち、形態変化装置１の姿勢が重力方向に対して平行となる形）にしたときに、誤って操作部材７０を操作してしまい係合凹部３０と係合部材５０の係合が外れて、第１の部材１１が自重により第２の部材１２の上面４１から落下して不意に自動車形態からロボット形態に変化し、第１の部材１１の後面２４と第２の部材１２の前面４３との間、または、第１の部材１１の下面２２と接地面との間で指を挟んで怪我をしてしまう等の危険を防止することができる。 In the above-described embodiment, the locking member 65 locks the engagement member 50 so that the engagement member 50 cannot be released, or unlocks the lock. However, the operation member 70 that operates the engagement member 50 may be locked. Absent. The shape change device 1 has a vertically long shape in which the first member 11 is placed with the second member 12 down at the engagement position of the engagement member 50 (that is, the posture of the shape change device 1 is in the direction of gravity. When the lower surface 42 of the second member 12 faces downward, the lock member 65 moves to the lock position (contact position, locking hole 67) by its own weight, and the operation member 70 is moved. The first member 11 and the second member 12 are separated from each other by locking so that the engagement member 50 cannot be disengaged. As a result, when the vertically long shape (that is, the shape of the shape change device 1 is parallel to the direction of gravity) in which the first member 11 is placed with the second member 12 facing down, The operating member 70 is operated and the engaging recess 30 and the engaging member 50 are disengaged, and the first member 11 falls from the upper surface 41 of the second member 12 due to its own weight and unexpectedly starts from the automobile form. It changes into a robot form, and an injury is caused by sandwiching a finger between the rear surface 24 of the first member 11 and the front surface 43 of the second member 12 or between the lower surface 22 of the first member 11 and the ground surface. It is possible to prevent dangers such as

また、形態変化装置１は、第２の部材１２の下面４２を略水平方向に向けて第１の部材１１と第２の部材１２を横長の形（すなわち、形態変化装置１の姿勢が重力方向に対して垂直となる形）にすると、この場合は誤って操作部材７０を操作してしまい係合凹部３０と係合部材５０の係合が外れたとしても、第１の部材１１の重量により不意に自動車形態からロボット形態に変化して怪我をしてしまうようなことはないので、ロック部材６５は自重により非ロック位置（非当接位置、凹部６６）に移動して操作部材７０のロックを解
除し、操作部材７０による係合部材５０の係合解除をできるようにして第１の部材１１と第２の部材１２が分離することを可能にする。このように、形態変化装置１は、形態変化装置１の重力方向に対する姿勢に応じて、ロック部材６５が自重によって移動することにより、係合部材５０の係合を解除する操作部材７０を操作不能にロックしたり、ロック解除したりすることができる。 In addition, the shape change device 1 has the first member 11 and the second member 12 in a horizontally long shape with the lower surface 42 of the second member 12 oriented in a substantially horizontal direction (that is, the posture of the shape change device 1 is in the direction of gravity. In this case, even if the operation member 70 is erroneously operated and the engagement recess 30 and the engagement member 50 are disengaged, the weight of the first member 11 Since there is no possibility of injuries due to a sudden change from the automobile form to the robot form, the lock member 65 moves to the non-lock position (non-contact position, recess 66) by its own weight, and the operation member 70 is locked. And the engagement member 50 can be disengaged by the operation member 70, so that the first member 11 and the second member 12 can be separated. As described above, the shape change device 1 cannot operate the operation member 70 that releases the engagement of the engagement member 50 when the lock member 65 is moved by its own weight according to the posture of the shape change device 1 with respect to the gravity direction. Can be locked or unlocked.
