特許第４２０３７９４号公報Japanese Patent No. 4203794

最近の引戸はスライド方向の抵抗が非常に小さく滑らかにスライドするように構成されており、この種の引戸を開閉操作する際、操作者、特に高齢者や身体的弱者は引戸のスライド動作に身体が追従できずにバランスを崩してしまうことがある。このような場合、操作者はそのまま取手に掴まろうとするが、戸がスライド動作を続けた際は取手も移動するので、操作者は移動する取手に誘導されてさらにバランスを崩し、転倒することが起こり得る。引戸において、このような転倒を防止するための対策は、従来よりほとんどなされていなかった。 Recent sliding doors are constructed so that sliding resistance is very small and slides smoothly, and when opening and closing this kind of sliding doors, operators, especially elderly people and physically weak people, are physically affected by sliding movements. May fail to follow and lose balance. In such a case, the operator tries to grasp the handle as it is, but when the door continues to slide, the handle also moves, so the operator may be guided by the moving handle to further lose balance and fall. Can happen. In sliding doors, there have been few measures for preventing such a fall.

特許文献１は、引戸の開度を保持する技術を開示するものであり、この技術を用いても引戸を開閉操作する際の操作者の転倒防止を図ることができない。因みに、特許文献１の開戸保持装置を動作させるにはストッパ手段を手又は足で操作しなければならず、操作者がバランスを崩した後には、操作が間に合わない。また、操作者がバランスを崩している状態、特に取手に掴まっている状態では、手又は足でストッパ手段の操作を行うことはできず、操作者の転倒防止用としては使用することができない。 Patent Document 1 discloses a technique for maintaining the opening degree of a sliding door, and even if this technique is used, it is impossible to prevent the operator from falling when the sliding door is opened and closed. Incidentally, in order to operate the open door holding device of Patent Document 1, the stopper means must be operated by hand or foot, and the operation is not in time after the operator loses balance. In addition, when the operator is out of balance, in particular, being held by the handle, the stopper means cannot be operated with the hand or foot, and cannot be used for preventing the operator from falling.

従って本発明の目的は、操作者がバランスを崩した際に取手に掴まることのみで、戸体の開閉を一時的に停止でき、これによって操作者の転倒を防止することを可能とする取手取り付け具及び戸体の開閉制動装置を提供することにある。 Accordingly, an object of the present invention is to make it possible to temporarily stop the opening and closing of the door body only by grasping the handle when the operator loses balance, thereby preventing the operator from falling over. An object of the present invention is to provide an opening / closing brake device for a fixture and a door.

本発明によれば、取手取り付け具は、長尺の取手の一端が床面に当接した第１の状態と取手の一端が床面から離れた第２の状態とを取手に与えることができるように取手を戸体の上下方向に移動可能に取り付けるための取手取り付け具であって、戸体に取り付けられるベース部材と、一部がベース部材に対して上下方向に移動可能に取り付けられており、他部が取手に取り付けられる可動部材と、取手が第１の状態から第２の状態に復帰するように、可動部材の上述の移動を付勢する復帰機構とを備えている。 According to the present invention, the handle attachment tool can provide the handle with the first state in which one end of the long handle is in contact with the floor surface and the second state in which one end of the handle is separated from the floor surface. Is a handle attachment for attaching the handle movably in the vertical direction of the door body, and a base member attached to the door body, and a part thereof is attached movably in the vertical direction with respect to the base member The movable member is provided with the other part attached to the handle, and the return mechanism that urges the movement of the movable member so that the handle returns from the first state to the second state.

本発明の取手取り付け具は、例えば引戸等の戸体に長尺の取手を取り付ける際に使用される。即ち、ベース部材を戸体に取り付け、可動部材の一部を取手に取り付けることによって設置される。可動部材の他部がベース部材に対して上下方向に移動可能に取り付けられており、復帰機構によって、取手が第１の状態（取手の一端が床面に当接した状態）から第２の状態（取手の一端が床面から離れた状態）に復帰するように、可動部材の移動が付勢されるため、取手に下方向の力が全く又はほとんどかかっていない場合は、取手は第２の状態にあり、戸板は通常の開閉動作を行うことが可能となる。一方、戸板を開閉させようとした際に、操作者がバランスを崩すなどして取手に掴まり体重がかかると、取手に下方向の力が印加される。この下方向の力により、可動部材が移動して取手が下方向に移動し第１の状態となることから、戸体の開閉が一時的に停止される。これにより、操作者の転倒を未然に防止することが可能となる。取手の下方向への力が解除されると、可動部材の移動が復帰機構によって付勢され、取手は第２の状態に戻り、戸板は通常の開閉動作を行える状態となる。 The handle attachment tool of the present invention is used when, for example, a long handle is attached to a door body such as a sliding door. That is, it is installed by attaching the base member to the door and attaching a part of the movable member to the handle. The other part of the movable member is attached to the base member so as to be movable in the vertical direction. The return mechanism causes the handle to move from the first state (one end of the handle abuts against the floor surface) to the second state. Since the movement of the movable member is urged so that it returns to the state (one end of the handle is away from the floor surface), if the handle has no or little downward force, the handle is In this state, the doorboard can perform a normal opening / closing operation. On the other hand, when the operator tries to open and close the door plate, if the operator grasps the handle and takes weight by breaking the balance, a downward force is applied to the handle. Due to this downward force, the movable member moves and the handle moves downward to enter the first state, so that the opening and closing of the door is temporarily stopped. Thereby, it is possible to prevent the operator from falling down. When the downward force of the handle is released, the movement of the movable member is urged by the return mechanism, the handle returns to the second state, and the door plate is in a state in which a normal opening / closing operation can be performed.

可動部材が、一方の端部を支点としてベース部材に回動可能に軸支されており、他方の端部が取手に取り付けられるアーム部材であり、復帰機構が、取手が第１の状態（取手の一端が床面に当接した状態）から第２の状態（取手の一端が床面から離れた状態）に復帰するように、アーム部材の回動を付勢する復帰機構であることが好ましい。アーム部材の一方の端部を支点としてベース部材に回動可能に軸支されており、復帰機構によって、取手が第１の状態から第２の状態に復帰するように、アーム部材の回動が付勢されるため、取手に下方向の力が全く又はほとんどかかっていない場合は、取手は第２の状態にあり、戸板は通常の開閉動作を行うことが可能となる。一方、戸板を開閉させようとした際に、操作者がバランスを崩すなどして取手に掴まり体重がかかると、取手に下方向の力が印加される。この下方向の力により、アーム部材が回動して取手が下方向に移動し第１の状態となることから、戸体の開閉が一時的に停止される。これにより、操作者の転倒を未然に防止することが可能となる。取手の下方向への力が解除されると、アーム部材の回動が復帰機構によって付勢され、取手は第２の状態に戻り、戸板は通常の開閉動作を行える状態となる。 The movable member is pivotally supported by the base member with one end serving as a fulcrum, and the other end is an arm member attached to the handle. The return mechanism has the handle in the first state (the handle It is preferable that the return mechanism is a return mechanism that biases the rotation of the arm member so as to return from the state where one end of the arm is in contact with the floor surface to the second state (the state where one end of the handle is separated from the floor surface). . The arm member is pivotally supported by the base member with one end portion of the arm member as a fulcrum, and the arm member is rotated by the return mechanism so that the handle returns from the first state to the second state. When the handle is energized, if the handle has no or little downward force, the handle is in the second state, and the doorboard can perform a normal opening / closing operation. On the other hand, when the operator tries to open and close the door plate, if the operator grasps the handle and takes weight by breaking the balance, a downward force is applied to the handle. Due to this downward force, the arm member rotates and the handle moves downward to enter the first state, so that the opening and closing of the door is temporarily stopped. Thereby, it is possible to prevent the operator from falling down. When the downward force of the handle is released, the rotation of the arm member is urged by the return mechanism, the handle returns to the second state, and the door plate is in a state where a normal opening / closing operation can be performed.

アーム部材の他方の端部を支点として回動可能に軸支されたブラケット部材をさらに備えており、ブラケット部材が取手に取り付けられるように構成されていることが好ましい。回動可能に軸支されたブラケット部材をさらに備えているため、アーム部材はベース部材及びブラケット部材の双方に対して回動可能となる。 It is preferable that a bracket member pivotally supported by the other end of the arm member as a fulcrum is further provided, and the bracket member is configured to be attached to the handle. Since it further includes a bracket member that is pivotally supported, the arm member is rotatable with respect to both the base member and the bracket member.

復帰機構は、取手に下方向への所定力が印加された際に取手に第１の状態を与えるべくアーム部材の回動を制御するように構成されていることも好ましい。 It is also preferable that the return mechanism is configured to control the rotation of the arm member to give the handle a first state when a predetermined downward force is applied to the handle.

復帰機構は、ベース部材に固着され凹湾曲した前辺縁を備えたカム溝を有するカム部材と、アーム部材に沿って移動可能であり、カム部材のカム溝に当接可能な凸状先端部を有する摺動部材と、摺動部材の凸状先端部をカム部材のカム溝に押圧させる付勢部材とを備えていることが好ましい。取手に力が加えられていないときは、摺動部材の凸状先端部が、付勢部材によってカム部材の凹状のカム溝の底部に押し当てられ位置固定されることから、アーム部材の回動がその状態に保持され、取手は第２の状態を維持する。取手に上下方向の力が加えられると、アーム部材は付勢部材の付勢する力に抗って回動する。即ち、凸状先端部がカム溝の前辺縁に沿って移動することにより、この摺動部材が付勢部材の付勢する力に抗って後方に移動する。これにより、取手は第１の状態となる。取手に加えられる力が軽減されるか又はなくなると、摺動部材は付勢部材の付勢力によってベース部材方向に移動し、凸状先端部がカム溝の前辺縁に沿って移動して凹湾曲した底部に嵌合し、これによりアーム部材の回動が復帰して取手は第２の状態に戻る。この復帰機構では、凸状先端部及びカム溝の凹湾曲した前辺縁の表面形状の設計並びに付勢部材の付勢力の設定によって取手の移動に要する力や取手の移動範囲を設定できる。 The return mechanism includes a cam member having a cam groove having a front edge that is fixed to the base member and has a concave curve, and a convex tip portion that is movable along the arm member and can contact the cam groove of the cam member And a biasing member that presses the convex tip of the sliding member against the cam groove of the cam member. When no force is applied to the handle, the projecting tip of the sliding member is pressed against the bottom of the concave cam groove of the cam member by the biasing member, and the position is fixed. Is held in that state, and the handle maintains the second state. When a vertical force is applied to the handle, the arm member rotates against the urging force of the urging member. That is, when the convex tip portion moves along the front edge of the cam groove, the sliding member moves backward against the urging force of the urging member. Thereby, a handle will be in a 1st state. When the force applied to the handle is reduced or eliminated, the sliding member moves toward the base member by the urging force of the urging member, and the convex tip moves along the front edge of the cam groove to form a concave. The arm is fitted to the curved bottom, whereby the pivoting of the arm member is restored and the handle returns to the second state. In this return mechanism, the force required to move the handle and the range of movement of the handle can be set by designing the surface shape of the convex front end and the front edge of the cam groove that is concavely curved and setting the urging force of the urging member.

付勢部材は、一端が摺動部材の後端面に当接して押圧するコイルバネであることが好ましい。付勢部材に、摺動部材を押圧するコイルバネを選択することによって、付勢部材の付勢する力の設定が適切かつ容易に行える。 The biasing member is preferably a coil spring whose one end is in contact with and presses the rear end surface of the sliding member. By selecting a coil spring that presses the sliding member as the urging member, the force urging the urging member can be set appropriately and easily.

カム部材の前辺縁は中心軸に対して左右対称に凹湾曲しており、アーム部材は支点に対して両方向に対称に回動可能であることも好ましい。取手取り付け具を戸体の反対側の面に設置した際も同様に動作することができる。従って、取手取り付け具は、部材を変更することなく戸体の表裏いずれの面にも用いることができる。 It is also preferable that the front edge of the cam member is concavely curved symmetrically with respect to the central axis, and the arm member can be rotated symmetrically in both directions with respect to the fulcrum. The same operation can be performed when the handle attachment is installed on the opposite surface of the door. Therefore, the handle attachment can be used on both the front and back surfaces of the door without changing the members.

アーム部材は、カム部材を相対的に回動可能に受け入れる第１の空洞部と、第１の空洞部に連通しており、摺動部材及び付勢部材を摺動自在に収容する第２の空洞部とを備えていることが好ましい。摺動部材及び付勢部材がアーム部材の空洞部内に収納されているので、これらの部材が破損しにくく、また、戸体の外観を損なわない。 The arm member communicates with the first cavity portion that receives the cam member so as to be relatively rotatable, and the second cavity portion slidably accommodates the sliding member and the urging member. It is preferable to provide a cavity. Since the sliding member and the urging member are accommodated in the cavity of the arm member, these members are not easily damaged, and the appearance of the door body is not impaired.

本発明によれば、さらに、戸体の開閉制動装置は、複数の取手取り付け具と、複数の取手取り付け具によって、一端が床面に当接した第１の状態と一端が床面から離れた第２の状態とが付与されるように戸体の上下方向に移動可能に取り付けられた長尺の取手とを備えており、複数の取手取り付け具の各々が、戸体に取り付けられるベース部材と、一部がベース部材に対して上下方向に移動可能に取り付けられており、他部が取手に取り付けられる可動部材と、取手が第１の状態から第２の状態に復帰するように、可動部材の移動を付勢する復帰機構とを備えている。 According to the present invention, the door opening and closing braking device further includes a plurality of handle attachments and a plurality of handle attachments, wherein the first state where one end abuts against the floor surface and one end separates from the floor surface. A long handle attached to be movable in the vertical direction of the door body so that the second state is provided, and each of the plurality of handle attachment tools includes a base member attached to the door body, The movable member is attached to a part of the base member so as to be movable in the vertical direction, the other part is attached to the handle, and the movable member so that the handle returns from the first state to the second state. And a return mechanism for energizing the movement of.

本発明の開閉制動装置は、複数の取手取り付け具を例えば引戸等の戸体に長尺の取手の取り付けに使用して構成されている。各取手取り付け具は、ベース部材を戸体に取り付け、可動部材の一部を取手に取り付けることによって設置される。可動部材の他部がベース部材に対して上下方向に移動可能に取り付けられており、復帰機構によって、取手が第１の状態（取手の一端が床面に当接した状態）から第２の状態（取手の一端が床面から離れた状態）に復帰するように、可動部材の移動が付勢されるため、取手に下方向の力が全く又はほとんどかかっていない場合は、取手は第２の状態にあり、戸板は通常の開閉動作を行うことが可能となる。一方、戸板を開閉させようとした際に、操作者がバランスを崩すなどして取手に掴まり体重がかかると、取手に下方向の力が印加される。この下方向の力により、可動部材が移動して取手が下方向に移動し第１の状態となることから、戸体の開閉が一時的に停止される。これにより、操作者の転倒を未然に防止することが可能となる。取手の下方向への力が解除されると、可動部材の移動が復帰機構によって付勢され、取手は第２の状態に戻り、戸板は通常の開閉動作を行える状態となる。 The open / close braking device of the present invention is configured by using a plurality of handle attachments for attaching a long handle to a door body such as a sliding door. Each handle attachment is installed by attaching the base member to the door and attaching a part of the movable member to the handle. The other part of the movable member is attached to the base member so as to be movable in the vertical direction. The return mechanism causes the handle to move from the first state (one end of the handle abuts against the floor surface) to the second state. Since the movement of the movable member is urged so that it returns to the state (one end of the handle is away from the floor surface), if the handle has no or little downward force, the handle is In this state, the doorboard can perform a normal opening / closing operation. On the other hand, when the operator tries to open and close the door plate, if the operator grasps the handle and takes weight by breaking the balance, a downward force is applied to the handle. Due to this downward force, the movable member moves and the handle moves downward to enter the first state, so that the opening and closing of the door is temporarily stopped. Thereby, it is possible to prevent the operator from falling down. When the downward force of the handle is released, the movement of the movable member is urged by the return mechanism, the handle returns to the second state, and the door plate is in a state in which a normal opening / closing operation can be performed.

可動部材が、一方の端部を支点としてベース部材に回動可能に軸支されており、他方の端部が取手に取り付けられるアーム部材であり、復帰機構が、取手が第１の状態から第２の状態に復帰するように、アーム部材の回動を付勢する復帰機構であることが好ましい。アーム部材の一方の端部を支点としてベース部材に回動可能に軸支されており、復帰機構によって、取手が第１の状態（取手の一端が床面に当接した状態）から第２の状態（取手の一端が床面から離れた状態）に復帰するように、アーム部材の回動が付勢されるため、取手に下方向の力が全く又はほとんどかかっていない場合は、取手は第２の状態にあり、戸板は通常の開閉動作を行うことが可能となる。一方、戸板を開閉させようとした際に、操作者がバランスを崩すなどして取手に掴まり体重がかかると、取手に下方向の力が印加される。この下方向の力により、アーム部材が回動して取手が下方向に移動し第１の状態となることから、戸体の開閉が一時的に停止される。これにより、操作者の転倒を未然に防止することが可能となる。取手の下方向への力が解除されると、アーム部材の回動が復帰機構によって付勢され、取手は第２の状態に戻り、戸板は通常の開閉動作を行える状態となる。 The movable member is pivotally supported on the base member with one end serving as a fulcrum, and the other end is an arm member attached to the handle, and the return mechanism has the handle from the first state to the first state. A return mechanism that biases the rotation of the arm member so as to return to the state 2 is preferable. The arm member is pivotally supported by the base member with one end of the arm member as a fulcrum, and the return mechanism causes the handle to move from the first state (one end of the handle abuts against the floor surface) to the second state. Since the arm member is pivoted so that it returns to the state (one end of the handle is away from the floor), the handle will be the first when no or little downward force is applied to the handle. In the state of 2, the doorboard can perform a normal opening / closing operation. On the other hand, when the operator tries to open and close the door plate, if the operator grasps the handle and takes weight by breaking the balance, a downward force is applied to the handle. Due to this downward force, the arm member rotates and the handle moves downward to enter the first state, so that the opening and closing of the door is temporarily stopped. Thereby, it is possible to prevent the operator from falling down. When the downward force of the handle is released, the rotation of the arm member is urged by the return mechanism, the handle returns to the second state, and the door plate is in a state where a normal opening / closing operation can be performed.

複数の取手取り付け具の各々のアーム部材は、アーム部材の他方の端部を支点として回動可能に軸支されたブラケット部材をさらに備えており、ブラケット部材が取手に取り付けられるように構成されていることが好ましい。回動可能に軸支されたブラケット部材をさらに備えているため、アーム部材はベース部材及びブラケット部材の双方に対して回動可能となる。 Each arm member of the plurality of handle attachments further includes a bracket member pivotally supported with the other end of the arm member as a fulcrum, and the bracket member is configured to be attached to the handle. Preferably it is. Since it further includes a bracket member that is pivotally supported, the arm member is rotatable with respect to both the base member and the bracket member.

複数の取手取り付け具の各々の復帰機構は、取手に下方向への所定力が印加された際に取手に第１の状態を与えるべくアーム部材の回動を制御するように構成されていることも好ましい。 Each return mechanism of the plurality of handle attachments is configured to control the rotation of the arm member to give the handle a first state when a predetermined downward force is applied to the handle.

The tip of the coil spring 16 is in contact with the sliding member 15 in the concave hole 15b, and the rear end thereof is in contact with the bracket-side inner wall of the second cavity portion 12d of the arm member 12. Accordingly, the coil spring 16 presses and urges the sliding member 15 in the direction of the convex tip portion 15a. In the present embodiment, the sliding member 15 is formed of a resin material such as polyacetal resin. The cam member 14, the sliding member 15, and the coil spring 16 in this embodiment are the main components of the return mechanism of the present invention.

As described above, the arm member 12 is pivotally supported by the bracket member 13 so as to be rotatable at the bracket side fulcrum. In the present embodiment, the bracket member 13 is formed by die-casting a zinc alloy, but may be formed using other metal material or resin material.

以下、本実施形態における開閉制動装置１００の動作を説明する。 Hereinafter, the operation of the open / close braking device 100 in the present embodiment will be described.

取手取り付け具１０は、取手２０を操作していない際や、戸体１２０をスライドさせるために取手２０に水平方向の力を印加して操作をしている際は、取手２０に下方向の力が全く又はほとんどかからないため、図２及び図４に示すようにアーム部材１２は一定方向、図２及び図４において水平方向（以下初期方向と称する）を向くように維持されている。逆に、取手２０に下方向の力が全く又はほとんどかからない状態で、アーム部材１２が初期方向を向くようにベース部材１１を戸体１２０の表面１２０ｂに取り付ける。このとき、図６（Ａ）に示すように、取手２０の下端が床面１４０から離れた第２の状態に維持され、戸板１２０は通常の開閉動作を行うことが可能となる。この第２の状態では、図４（Ａ）に示すように、摺動部材１５の凸状先端部１５ａがカム部材１４におけるカム溝１４ａの凹湾曲した底部１４ｂに当接しコイルバネ１６の付勢力によって押圧している。これにより、アーム部材１２は初期方向に向くように維持されている。 The handle mounting tool 10 has a downward force applied to the handle 20 when the handle 20 is not operated or when a horizontal force is applied to the handle 20 to slide the door 120. Therefore, as shown in FIGS. 2 and 4, the arm member 12 is maintained so as to face a fixed direction, that is, a horizontal direction (hereinafter referred to as an initial direction) in FIGS. On the contrary, the base member 11 is attached to the surface 120b of the door 120 so that the arm member 12 faces the initial direction with no or little downward force applied to the handle 20. At this time, as shown in FIG. 6A, the lower end of the handle 20 is maintained in the second state away from the floor surface 140, and the doorboard 120 can perform a normal opening / closing operation. In this second state, as shown in FIG. 4A, the convex tip portion 15 a of the sliding member 15 abuts on the concave curved bottom portion 14 b of the cam groove 14 a in the cam member 14, and the biasing force of the coil spring 16 Pressing. Thereby, the arm member 12 is maintained so as to face the initial direction.

取手２０に下方向の力がかかった場合、例えば操作者がバランスを崩して取手２０に掴まり体重をかけた場合等に、その下方向の力がコイルバネ１６の付勢力によって生じる力Ｆを超えると、図５に示すようにアーム部材１２が初期方向から回動する。即ち、図５（Ｂ）に示すように、コイルバネ１６の付勢力によって摺動部材１５の凸状先端部１５ａがカム部材１４のカム溝１４ａの凹状の底部１４ｂに当接している力に対応するアーム部材１２の先端部（ブラケット側支点）の力Ｆに対して、印加される下方向の力が大きくなると、摺動部材１５の凸状先端部１５ａの当接点がカム溝１４ａの凹状の底部１４ｂから外れ、カム溝１４ａの前辺縁に沿って移動する。これにより、アーム部材１２はベース側支点を中心に下方向に回動する。即ち、アーム部材１２は、図５（Ａ）に示すように、θ_０の初期方向からθ_１の作動時角度方向に回動する。 When a downward force is applied to the handle 20, for example, when the operator loses balance and grips the handle 20 to apply weight, the downward force exceeds the force F generated by the biasing force of the coil spring 16. As shown in FIG. 5, the arm member 12 rotates from the initial direction. That is, as shown in FIG. 5B, this corresponds to the force that the convex tip 15 a of the sliding member 15 is in contact with the concave bottom 14 b of the cam groove 14 a of the cam member 14 by the biasing force of the coil spring 16. When the applied downward force increases with respect to the force F at the tip end (bracket side fulcrum) of the arm member 12, the contact point of the convex tip 15a of the sliding member 15 becomes the concave bottom of the cam groove 14a. 14b moves along the front edge of the cam groove 14a. As a result, the arm member 12 rotates downward about the base side fulcrum. That is, as shown in FIG. 5A, the arm member 12 rotates from the initial direction of θ ₀ in the operating angular direction of θ ₁ .

アーム部材１２が作動時角度方向θ_１に回動すると、図６（Ｂ）に示すように、ブラケット部材１３を介してこのアーム部材１２に連結されている取手２０の下端が床面１４０からに当接した第１の状態となる。これにより、取手２０の下端に設けられた摺動抵抗部材２１が床面１４０に押し付けられる。摺動抵抗部材２１は、床面１４０に押圧された力に応じた摩擦力を発生し、これによって取手２０の水平方向への移動が制止される。 When the arm member 12 is pivoted in the operating time of the angle direction theta _1, as shown in FIG. 6 (B), via the bracket member 13 to the lower end of the handle 20 which is connected to the arm member 12 from the floor 140 The first state comes into contact. Thereby, the sliding resistance member 21 provided at the lower end of the handle 20 is pressed against the floor surface 140. The sliding resistance member 21 generates a frictional force according to the force pressed against the floor surface 140, and thereby the movement of the handle 20 in the horizontal direction is stopped.

このように、操作者が取手２０に掴まって体重をあずけた際に、取手２０の水平方向への移動が制止され、戸体１２０のスライド（開閉）が阻止され、操作者の転倒を防止することができる。 In this way, when the operator grabs the handle 20 and gains weight, the movement of the handle 20 in the horizontal direction is stopped, the door 120 is prevented from sliding (opening and closing), and the operator is prevented from falling. be able to.

摺動抵抗部材２１の摩擦力は、床面１４０に強く押し付けるほど増大するため、取手２０に掴まって下方向に押す力が強くなればなるほど制止力は大きくなり、より安全に戸体１２０の開閉動作を停止させることができる。本実施形態のごとく、摩擦力で固着する構造は取手２０の下端部に容易かつ安価に設けることができ、床面１４０には特に部材などを設ける必要もない。 Since the frictional force of the sliding resistance member 21 increases as it strongly presses against the floor surface 140, the restraining force increases as the gripping force on the handle 20 and the downward pressing force increases, and the door 120 can be opened and closed more safely. The operation can be stopped. As in the present embodiment, the structure that is fixed by frictional force can be easily and inexpensively provided at the lower end of the handle 20, and there is no need to provide a member or the like on the floor surface 140 in particular.

掴まっていた操作者がバランスを取り戻すなどで、アーム部材１２に対して下方向にかかる力が、前述の力Ｆより小さくなると、コイルバネ１６の付勢力によって、摺動部材１５の凸状先端部１５ａの当接点がカム溝の１４ａの前辺縁に沿って移動し凹状の底部１４ｂまで移動する。これにより、アーム部材１２が回動して作動時角度方向θ_１から初期方向θ_０の方向に復帰する。その結果、取手２０は上方向に移動してその下端が床面１４０から離れた第２の状態に復帰し、戸体１２０の開閉動作が可能となる。 When the force applied downward to the arm member 12 becomes smaller than the above-described force F, for example, when the operator who has grasped regains balance, the convex tip portion 15a of the sliding member 15 is applied by the biasing force of the coil spring 16. Is moved along the front edge of the cam groove 14a to the concave bottom portion 14b. As a result, the arm member 12 rotates and returns from the operating angular direction θ ₁ to the initial direction θ ₀ . As a result, the handle 20 moves upward and returns to the second state in which the lower end is separated from the floor surface 140, and the door 120 can be opened and closed.

以上説明したように、本実施形態によれば、取手２０を戸体に取り付ける取手取り付け具１０に開閉を制動する機構が設けられているため、取手２０とは別にストッパ手段などを設ける必要がなく、引戸の構造を複雑化することなく、操作者の転倒を防止することができる。また、本実施形態の取手取り付け具１０は部品数が少なく構造も簡素で、製造が容易である。さらに、既存の引戸に対しても、取手２０の部品を一部取り替えるのみで取り付けすることが可能である。 As described above, according to the present embodiment, the handle attachment 10 that attaches the handle 20 to the door is provided with a mechanism for braking the opening and closing, so there is no need to provide a stopper means or the like separately from the handle 20. The operator can be prevented from falling without complicating the structure of the sliding door. In addition, the handle attachment tool 10 of the present embodiment has a small number of parts, a simple structure, and is easy to manufacture. Furthermore, it is possible to attach to existing sliding doors by only partially replacing parts of the handle 20.

本実施形態によれば、取手取り付け具１０は、カム溝１４ａが底部１５ｂに対して軸対称となるよう形成されているので、アーム部材１２はいずれの方向に対しても同様に回動動作が可能となっている。そのため、取手取り付け具１０を戸体１２０の表面１２０ｂとは逆側の表面に設置した際は、上述の説明とは左右逆に取り付けられるが、この際も上述と同様に動作することができる。従って、この取手取り付け具１０は、部材を変更することなく戸体１２０の表裏いずれの面にも用いることができる。 According to the present embodiment, the handle fitting 10 is formed so that the cam groove 14a is axially symmetric with respect to the bottom portion 15b. Therefore, the arm member 12 is similarly rotated in any direction. It is possible. Therefore, when the handle attachment tool 10 is installed on the surface opposite to the surface 120b of the door 120, it is attached in the opposite direction to the above description, but in this case, the same operation as described above can be performed. Therefore, this handle fitting 10 can be used on either the front or back surface of the door 120 without changing the members.

本実施形態の変更態様として、ベース部材１１とカム部材１４とを別個に形成した後、両者を固着して一体化しても良い。 As a modification of this embodiment, after the base member 11 and the cam member 14 are formed separately, they may be fixed and integrated.

A plurality of receiving members 70 are fixed in a row on the floor surface 140 '. In the example shown in the figure, the receiving member 70 is fixed to the floor surface 140 ′ with a wood screw, but may be attached with a double-sided tape or the like. The receiving member 70 and the convex member 71 are desirably formed of a metal material such as stainless steel, but may be formed of a resin material.

本実施形態の開閉制動装置におけるその他の構成は、第１の実施形態の場合と同様である。取手２０′の凸状部材７１の真下に受け部７０のストッパ溝７０ａが位置している際に、操作者がバランスを崩して取手２０′に掴まること等により、この取手２０′が下方に移動すると、凸状部材７１の先端部７１ａが受け部７０のストッパ溝７０ａに係合する。この状態で、凸状部材７１がストッパ溝７０ａ内をスライドし、ストッパ溝７０ａの端縁７０ｂに当接することによってそのスライドが停止し、取手２０′の水平方向の移動が制止される。その結果、戸板のスライドによる転倒が防止できる。 Other configurations of the open / close braking device of the present embodiment are the same as those of the first embodiment. When the stopper groove 70a of the receiving portion 70 is located directly below the convex member 71 of the handle 20 ', the operator loses the balance and is gripped by the handle 20'. When moved, the tip end portion 71 a of the convex member 71 engages with the stopper groove 70 a of the receiving portion 70. In this state, the convex member 71 slides in the stopper groove 70a and comes into contact with the end edge 70b of the stopper groove 70a, so that the slide is stopped, and the horizontal movement of the handle 20 'is stopped. As a result, it is possible to prevent the doorboard from falling due to sliding.

本実施形態では、取手２０′が摺動による摩擦力ではなく、機械的な当接によって制止されるので、強固な制止が可能で、摺動部材の磨耗等による破損も起こりにくい。 In this embodiment, the handle 20 ′ is restrained not by frictional force due to sliding but by mechanical contact, so that it can be firmly restrained, and damage due to wear or the like of the sliding member hardly occurs.

本実施形態のその他の構成及び作用効果は、第１の実施形態と同様である。 Other configurations and operational effects of the present embodiment are the same as those of the first embodiment.

上述の実施形態においては、長尺の取手の伸長方向が戸体の上下方向となるように、取手取り付け具を戸体に取り付けている。即ち、取手取り付け具のアーム部材の初期方向が水平方向となるように、ベース部材を戸体に固着している。しかしながら、アーム部材の初期方向が水平方向から若干傾斜した方向となるようにベース部材を戸体に固着すれば、取手に傾斜した側から水平方向に、コイルバネ１６の付勢力によって生じる力Ｆを超える力が働くと、第１の状態を実現させ、開又は閉を制動させることが可能となる。 In the above-described embodiment, the handle attachment is attached to the door so that the extending direction of the long handle is the vertical direction of the door. That is, the base member is fixed to the door so that the initial direction of the arm member of the handle attachment is horizontal. However, if the base member is fixed to the door so that the initial direction of the arm member is slightly inclined from the horizontal direction, the force F generated by the biasing force of the coil spring 16 is exceeded in the horizontal direction from the side inclined to the handle. When the force is applied, the first state can be realized and the opening or closing can be braked.

なお、上述の実施形態は本発明の開閉制動装置を上吊り式のアウトセット引戸に適用した例であるが、本発明の開閉制動装置はそれ以外の引戸にも適用することができ、また、引戸以外の戸、例えば開き戸にも適用することが可能である。また、上述の実施形態では、戸体に２つの取手取り付け具を設けているが、３つ以上の取手取り付け具を設けても良いことはもちろんである。 In addition, although the above-mentioned embodiment is an example which applied the opening-and-closing brake device of the present invention to the suspension type outset sliding door, the opening-and-closing braking device of the present invention can be applied to other sliding doors, The present invention can also be applied to a door other than a sliding door, for example, a hinged door. Moreover, in the above-mentioned embodiment, although the two handle attachments are provided in the door, it is needless to say that three or more handle attachments may be provided.

以上述べた実施形態においては、取手取り付け具として、アーム部材の回動により取手を上下方向に移動させるものであるが、取手に下方向の力が印加された際にこの取手を下方に移動させて第１の状態を実現し、その下方向の力が除去された際に取手を上方に移動させて第２の状態に復帰させる機構であれば、どのような構造であっても本発明を実現することが可能である。 In the embodiment described above, the handle attachment is a tool that moves the handle in the vertical direction by rotating the arm member, but when a downward force is applied to the handle, the handle is moved downward. As long as the mechanism realizes the first state and moves the handle upward when the downward force is removed to return to the second state, the present invention can be applied to any structure. It is possible to realize.

以上述べた実施形態は全て本発明を例示的に示すものであって限定的に示すものではなく、本発明は他の種々の変形態様及び変更態様で実施することができる。従って本発明の範囲は特許請求の範囲及びその均等範囲によってのみ規定されるものである。 All the embodiments described above are illustrative of the present invention and are not intended to be limiting, and the present invention can be implemented in other various modifications and changes. Therefore, the scope of the present invention is defined only by the claims and their equivalents.

本発明の取手取り付け具又は戸体の開閉制動装置は、戸体開閉時における開閉操作者の転倒を防止可能であるため、病院、老人ホーム又は通常の居住施設に適用でき、医療、福祉、居住等の分野に広く役立つものである。 The handle fitting or door opening / closing braking device of the present invention can prevent the operator from overturning when the door is opened and closed, and can be applied to hospitals, nursing homes, or ordinary residential facilities. It is useful for a wide range of fields.
