（引き違い戸板１０の構成）
以下、本発明が適用された自開機構１００およびこれを備える引き違い戸板１０について図面を用いて説明する。本実施形態にかかる引き違い戸板１０は、図１から図３に示すように、少なくとも、戸枠１１と、一対の戸板１２,１３と、レール１４と、ランナー１６と、自開機構１００とで構成されている。 (Structure of sliding door plate 10)
Hereinafter, the self-opening mechanism 100 to which the present invention is applied and the sliding door plate 10 provided with the self-opening mechanism 100 will be described with reference to the drawings. As shown in FIGS. 1 to 3, the sliding door plate 10 according to the present embodiment includes at least the door frame 11, the pair of door plates 12, 13 and the rail 14, the runner 16, and the self-opening mechanism 100. It is configured.

なお、本実施形態では、建屋内に設けられた戸枠１１で構成された、人や荷物が通る開口２０を開閉する「引戸」に引き違い戸板１０を適用した例を示しているが、本発明に係る自開機構１００およびこれを備える引き違い戸板１０の適用先はこれに限定されるものではなく、例えば、商店等に設置されたショーケースや、一般家庭内に設置されるキャビネット家具といったように大小様々な「引き違い戸板」を備えるものに適用することができる。 In the present embodiment, an example in which the sliding door plate 10 is applied to a "sliding door" that opens and closes an opening 20 through which people and luggage pass, which is composed of a door frame 11 provided in the building, is shown. The application destination of the self-opening mechanism 100 and the sliding door plate 10 provided with the self-opening mechanism 100 according to the invention is not limited to this, for example, a showcase installed in a store or the like, a cabinet furniture installed in a general household, or the like. It can be applied to those equipped with "sliding door plates" of various sizes.

戸枠１１は、一対の戸板１２，１３が滑動することによって開閉される開口２０を構成する部材である。
なお、戸枠１１を構成する材料は、必要は強度を担保できるものであれば、金属、樹脂、木材等どのような材料でも使用することができる。 The door frame 11 is a member constituting an opening 20 that is opened and closed by sliding a pair of door plates 12 and 13.
As the material constituting the door frame 11, any material such as metal, resin, and wood can be used as long as the strength can be ensured.

一対の戸板１２,１３は、上述のように戸枠１１によって構成された開口２０を開閉する板材である。 The pair of door plates 12 and 13 are plate materials that open and close the opening 20 formed by the door frame 11 as described above.

レール１４は、一対の戸板１２，１３を取り付ける開口２０の天面において、各戸板１２，１３のそれぞれに対して１つずつ取り付けられている。これにより、一対の戸板１２,１３は、互いに引き違うことができるようになっている。 One rail 14 is attached to each of the door plates 12 and 13 on the top surface of the opening 20 to which the pair of door plates 12 and 13 are attached. As a result, the pair of door plates 12 and 13 can be pulled apart from each other.

また、各レール１４は、戸板１２，１３の天面に取り付けられたランナー１６および後述するスライドアシスト装置１８が走行するランナー走行面２２を有している。なお、レール１４を構成する材料は、必要は強度を担保できるものであれば、金属、樹脂、木材等どのような材料でも使用することができる。 Further, each rail 14 has a runner 16 mounted on the top surfaces of the door plates 12 and 13 and a runner running surface 22 on which the slide assist device 18 described later travels. As the material constituting the rail 14, any material such as metal, resin, and wood can be used as long as the strength can be ensured.

本実施例の自開機構１００は、図１から図３に示すように、引きばね１７と、キャッチ４０とを備えている。 As shown in FIGS. 1 to 3, the self-opening mechanism 100 of this embodiment includes a pull spring 17 and a catch 40.

この引きばね１７には、引き伸ばされたストロークの長さに関係なく常にほぼ一定の引き戻し力となる「定荷重ばね」が使用されている。また、引きばね１７の一端（引きばね１７の本体側）は、一方の戸板１２における他方の戸板１３から遠い側の側面上方端部に例えばブラケット等を介して取り付けられている。さらに、引きばね１７の他端は、他方の戸板１３における一方の戸板１２から遠い側の側面上方端部に例えばブラケット等を介して取り付けられている。 As the pulling spring 17, a "constant load spring" that always has a substantially constant pulling force regardless of the length of the stretched stroke is used. Further, one end of the pull spring 17 (the main body side of the pull spring 17) is attached to the upper end of the side surface of one door plate 12 on the side far from the other door plate 13 via, for example, a bracket. Further, the other end of the pull spring 17 is attached to the upper end of the side surface of the other door plate 13 on the side far from the one door plate 12 via, for example, a bracket.

キャッチ４０は、戸板１２，１３を閉止位置で保持する付勢力を付与する部材である。このキャッチ４０は、一例として、図４に示すように、戸枠１１の両端部に固定される本体部４２と、当該本体部４２の略中央部から図中左下方に突設された係止部４４とを有している。 The catch 40 is a member that imparts urging force to hold the door plates 12 and 13 in the closed position. As an example, the catch 40 has a main body portion 42 fixed to both ends of the door frame 11 and a locking projecting from a substantially central portion of the main body portion 42 to the lower left in the drawing. It has a unit 44.

本体部４２の図中右端部には、キャッチ４０を戸枠１１に固定するための固定ネジ（図示せず）を挿通するための固定ネジ挿通孔４６が形成されている。また、本体部４２の図中左端部は、ランナー１６の車輪の径とほぼ同じ円弧状に形成されている。 A fixing screw insertion hole 46 for inserting a fixing screw (not shown) for fixing the catch 40 to the door frame 11 is formed at the right end of the main body 42 in the drawing. Further, the left end portion of the main body portion 42 in the drawing is formed in an arc shape substantially the same as the diameter of the wheel of the runner 16.

係止部４４は、上述のように本体部４２の略中央部から図中左下方に突設されていることから、その先端部４８が材料の弾性によって本体部４２に近接離間する方向にしなるようになっている。これにより、戸板１２，１３を閉止位置まで移動させたとき、図５に示すように、キャッチ４０における係止部４４の先端部４８が各戸板１２，１３に取り付けたランナー１６に係合するので、戸板１２，１３がそれぞれの閉止位置で保持されるようになっている。 Since the locking portion 44 projects from the substantially central portion of the main body portion 42 to the lower left in the drawing as described above, the tip portion 48 thereof is in a direction of being brought close to and separated from the main body portion 42 by the elasticity of the material. It has become like. As a result, when the door plates 12 and 13 are moved to the closing position, as shown in FIG. 5, the tip 48 of the locking portion 44 in the catch 40 engages with the runner 16 attached to the door plates 12 and 13. , Door plates 12 and 13 are held at their respective closing positions.

（自開機構１００の作用）
次に上述した引き違い戸板１０における自開機構１００の作用について説明する。最初に、両戸板１２，１３はそれぞれ閉じられた状態になっており（図２参照）、上述したように自開機構１００を構成するキャッチ４０が各戸板１２，１３に取り付けられたランナー１６に係合した状態になっている。この状態において、戸板１２，１３がそれぞれの閉止位置で保持されている。 (Action of self-opening mechanism 100)
Next, the operation of the self-opening mechanism 100 on the sliding door plate 10 described above will be described. First, both door plates 12 and 13 are in a closed state (see FIG. 2), and as described above, the catch 40 constituting the self-opening mechanism 100 is attached to the runners 16 attached to the door plates 12 and 13. It is in an engaged state. In this state, the door plates 12 and 13 are held at their respective closing positions.

この状態から、ユーザがキャッチ４０の保持力に抗していずれかの戸板１２，１３を開く方向に付勢すると、ランナー１６が移動してキャッチ４０との係合状態が解除され、祖の後、その戸板１２，１３が引きばね１７の弾性力によって残りの戸板１２，１３に引き寄せられていく（図３を参照）。このように戸板１２,１３の自開機能を実現することができる。 From this state, when the user urges the door plate 12 or 13 to open one of the door plates 12 and 13 against the holding force of the catch 40, the runner 16 moves and the engagement state with the catch 40 is released, and the ancestor's successor , The door plates 12 and 13 are attracted to the remaining door plates 12 and 13 by the elastic force of the pull spring 17 (see FIG. 3). In this way, the self-opening function of the door plates 12 and 13 can be realized.

また、自開機構１００を構成する引きばね１７は戸枠１１等を介さずに一対の戸板１２，１３の間に直接取り付けられているので、例えば、片方の戸板１２が残りの戸板１３側に移動して開いた状態（両戸板１２，１３が互いに重なった状態）を維持しつつ、両方の戸板１２，１３をまとめて移動させることができる（図６を参照）。 Further, since the pull spring 17 constituting the self-opening mechanism 100 is directly attached between the pair of door plates 12 and 13 without the intervention of the door frame 11 or the like, for example, one door plate 12 is on the remaining door plate 13 side. Both door plates 12 and 13 can be moved together while being moved and maintained in an open state (a state in which both door plates 12 and 13 overlap each other) (see FIG. 6).

（変形例１）
上述した実施形態では、戸板１２，１３を閉止位置に保持するための部材としてキャッチ４０を使用していたが、これに変えてスライドアシスト装置１８を使用してもよい。 (Modification example 1)
In the above-described embodiment, the catch 40 is used as a member for holding the door plates 12 and 13 in the closed position, but the slide assist device 18 may be used instead.

スライドアシスト装置１８は、戸板１２，１３に対し当該戸板１２，１３の閉止方向にスライドさせる付勢力を付与する装置である。もちろん、閉止方向だけでなく、開閉各方向に付勢力を付与するものであってもよい。なお、スライドアシスト装置１８は、レール１４に取り付けられたトリガー部材２４と共同して、付勢力を蓄積あるいは解放可能に構成されている。 The slide assist device 18 is a device that applies an urging force that slides the door plates 12 and 13 in the closing direction of the door plates 12 and 13. Of course, urging force may be applied not only in the closing direction but also in each opening / closing direction. The slide assist device 18 is configured to be able to accumulate or release the urging force in cooperation with the trigger member 24 attached to the rail 14.

このスライドアシスト装置１８は、一例として、図７に示すように、下面が開口する断面「コ」字状の上枠体２６と、上面が開口する断面「コ」字状の下枠体２８と、下枠体２８に一端が固定されたばね部材３０と、このばね部材３０と前後に並設されるとともに下枠体２８に一端が固定されたダンパー部材３２と、ばね部材３０およびダンパー部材３２の他端であるフリー端部に取り付けられ、上枠体２６内をその長手方向に沿ってスライド可能なスライド部材３４とを備えている。また、スライドアシスト装置１８における下枠体２８の一方端部には、ガイドローラ３６が設けられている。 As an example, the slide assist device 18 includes an upper frame body 26 having a “U” cross section with an open lower surface and a lower frame body 28 having a “U” cross section with an open upper surface, as shown in FIG. , A spring member 30 having one end fixed to the lower frame body 28, a damper member 32 which is juxtaposed with the spring member 30 and has one end fixed to the lower frame body 28, and a spring member 30 and a damper member 32. It is provided with a slide member 34 which is attached to the free end portion which is the other end and can slide in the upper frame body 26 along the longitudinal direction thereof. Further, a guide roller 36 is provided at one end of the lower frame body 28 in the slide assist device 18.

このスライドアシスト装置１８は、上述したガイドローラ３６が設けられた側とは反対側の端でランナー１６に連結されている。 The slide assist device 18 is connected to the runner 16 at an end opposite to the side on which the guide roller 36 is provided.

なお、図７では、ばね部材３０がダンパー部材３２の前後に一対配設されているが、ダンパー部材３２の前後いずれか一方に一本のばね部材３０を配設するなど、他の態様としてもよい。 In FIG. 7, a pair of spring members 30 are arranged in front of and behind the damper member 32, but another form such as arranging one spring member 30 in either front or rear of the damper member 32 may be used. Good.

（変形例１に係る自開機構１００の作用）
次に上述した変形例１に係る引き違い戸板１０における自開機構１００の作用について説明する。最初に、両戸板１２，１３はそれぞれ閉じられた状態になっており（図８および図９参照）、自開機構１００を構成する引きばね１７は最も長く伸びた状態になっている。この状態において、両戸板１２，１３には開く方向への付勢力が引きばね１７から与えられているが、両戸板１２，１３に設けられたスライドアシスト装置１８およびトリガー部材２４が協働して閉状態が保持されている。 (Action of Self-Opening Mechanism 100 Concerning Modification 1)
Next, the operation of the self-opening mechanism 100 on the sliding door plate 10 according to the above-mentioned modification 1 will be described. First, both door plates 12 and 13 are in a closed state (see FIGS. 8 and 9), and the pull spring 17 constituting the self-opening mechanism 100 is in the longest extended state. In this state, the pulling spring 17 applies an urging force to the door plates 12 and 13 in the opening direction, but the slide assist device 18 and the trigger member 24 provided on the door plates 12 and 13 cooperate with each other. The closed state is held.

この状態から、ユーザがスライドアシスト装置１８の保持力に抗していずれかの戸板１２，１３を開く方向に付勢すると、その戸板１２，１３が引きばね１７の弾性力によって残りの戸板１２，１３に引き寄せられていく（図１０を参照）。このように戸板１２,１３の自開機能を実現することができる。 From this state, when the user urges the door plates 12 and 13 to open one of the door plates 12 and 13 against the holding force of the slide assist device 18, the door plates 12 and 13 are moved by the elastic force of the pull spring 17 and the remaining door plates 12 and 13 are opened. It is attracted to 13 (see FIG. 10). In this way, the self-opening function of the door plates 12 and 13 can be realized.

なお、変形例１においても、自開機構１００を構成する引きばね１７は戸枠１１等を介さずに一対の戸板１２，１３の間に直接取り付けられているので、最初に説明した実施形態の場合と同様、例えば、片方の戸板１２が残りの戸板１３側に移動して開いた状態（両戸板１２，１３が互いに重なった状態）を維持しつつ、両方の戸板１２，１３をまとめて移動させることができる。 Also in the first modification, the pull spring 17 constituting the self-opening mechanism 100 is directly attached between the pair of door plates 12 and 13 without the intervention of the door frame 11 or the like. As in the case, for example, both door plates 12 and 13 are moved together while maintaining the open state (the state in which both door plates 12 and 13 overlap each other) by moving one door plate 12 to the remaining door plate 13 side. Can be made to.

（変形例２）
上述した実施形態や変形例１では、自開機構１００を構成する引きばね１７として「定荷重ばね」を使用していたが、引きばね１７はこれに限定されるものではなく、例えば、単なるゼンマイばねを使用してもよい。ただし、引き伸ばされたストロークの長さに関係なく常にほぼ一定の引き戻し力（付勢力）となる「定荷重ばね」を使用するのが好適である。 (Modification 2)
In the above-described embodiment and modification 1, a "constant load spring" is used as the pull spring 17 constituting the self-opening mechanism 100, but the pull spring 17 is not limited to this, and for example, a simple spring. Spring may be used. However, it is preferable to use a "constant load spring" that always has a substantially constant pulling force (urging force) regardless of the length of the stretched stroke.

（変形例３）
また、上述した実施形態や変形例１では、戸板１２,１３における引きばね１７の取付位置を各戸板１２,１３の側面上方端部にしていた。しかし、取付位置は「側面上方端部」に限定されるものではなく、例えば、側面の上下方向はどの位置であってもよいし、可能であれば各戸板１２,１３の側面ではなく天面や底面等に取り付けてもよい。 (Modification example 3)
Further, in the above-described embodiment and the first modification, the attachment position of the pull spring 17 on the door plates 12 and 13 is set to the upper end of the side surface of the door plates 12 and 13. However, the mounting position is not limited to the "upper end of the side surface". For example, the vertical direction of the side surface may be any position, and if possible, the top surface of the door plates 12 and 13 instead of the side surface. It may be attached to the bottom or the bottom.
