Description

本発明は、マンションや戸建住宅の玄関などの扉錠に関し、特に把手（ハンドル）を操作して扉を開放する時、小さい力でも確実に扉を開放することができるようにした、扉の開放力を助勢（アシスト）するようにした扉錠に関するものである。 The present invention relates to a door lock such as an entrance of a condominium or a detached house, and in particular, when opening a door by operating a handle (handle), the door can be surely opened even with a small force. The present invention relates to a door lock that assists the opening force.

近年、住宅の玄関扉は大型化され、それに伴い扉の開放には大きい力が必要となり、高齢者や子供にとっては大きな負担となっている。また、マンションなどの住居では、近年では高気密化されている為に、居室内の換気扇などの運転により、室内外での気圧差が生じて、玄関扉や間仕切扉の開放時に大きな力が必要となることがある。このような場合、特に高齢者や子供などは、扉の開放が困難となっている。 In recent years, the entrance doors of houses have been increased in size, and accordingly, a large force is required to open the doors, which is a great burden for elderly people and children. In addition, since residential buildings such as condominiums have become highly airtight in recent years, a large pressure difference is required when opening the entrance doors and partition doors due to the pressure difference between the inside and outside of the room due to the operation of ventilation fans in the room. It may become. In such a case, it is particularly difficult for elderly people and children to open the door.

従来、上記のような不具合を解消する為に種々の発明が提案されている。例えば、以下に示す特許文献１では、扉開放時に、把手の操作によって錠本体内に設けた突出杆を錠本体から突出させ、該突出杆の斜面部を枠側に設けた受座のローラに当接させることにより、扉の開放力を助勢（アシスト）するようにしている。 Conventionally, various inventions have been proposed in order to solve the above problems. For example, in Patent Document 1 shown below, when a door is opened, a protruding hook provided in the lock body is protruded from the lock body by a handle operation, and a sloped portion of the protruding hook is provided on a seat roller provided on the frame side. By making contact, the door opening force is assisted.

しかしながら、上記特許文献１の発明では、把手の操作によって錠本体内の突出杆を突出させるようにした錠本体やローラーを設けた受座などは、従来にはない新規な構造のものとなった。
従って、新規な錠本体や受座の製品化には、金型代など、高額な費用が必要であり、製品自体が高価なものとなった。
また、錠本体や受座の外形寸法も、必然的に従来のものとは異なり、扉や枠の加工寸法も従来とは異なる為、施行業者にとっても不都合であった。
更には、錠本体や受座の見栄えも悪く、しかも、把手を操作して扉を開放した時、錠本体からはラッチとは別の突出杆がラッチより大きく突出した状態となる為、人の通過時にこの突出杆に引っ掛かったりする虞もあった。 However, in the invention of the above-mentioned Patent Document 1, the lock body in which the protruding hook in the lock body is protruded by the operation of the handle, the receiving seat provided with the roller, etc. has a new structure that has not existed before. .
Accordingly, the commercialization of a new lock body and seat requires high costs such as mold costs, and the product itself is expensive.
In addition, the external dimensions of the lock main body and the seat are inevitably different from the conventional ones, and the processing dimensions of the door and the frame are also different from the conventional ones.
Furthermore, the appearance of the lock body and the seat is poor, and when the door is opened by operating the handle, the protruding protrusion from the lock body protrudes larger than the latch. There was also a risk of being caught by this protruding hook during passage.

本発明は上記従来の問題点を解消する為になされたもので、その第一の目的は、錠本体や受座以外の部分、例えば把手や座に開放力を助勢する機構を設けることにより、錠本体や受座は従来のものをそのまま使用することができる、扉の開放力を助勢するようにした扉錠を提供することにある。
また、第二の目的は、錠本体や受座の見栄えを損なうことなく、しかも、扉を開放して人が通過時に、突出杆に引っ掛かる虞れのない扉錠を提供することにある。
更に、第三の目的は、既設の扉錠に対し、把手と座を取り替え、当接部を取り付けるだけで、簡単に開放力を助勢できる扉錠を提供することができるようにしたことにある。 The present invention has been made to solve the above-mentioned conventional problems, and the first object thereof is to provide a mechanism for assisting the opening force in parts other than the lock body and the seat, for example, the handle and the seat, It is an object of the present invention to provide a door lock which can use a conventional lock body and a seat as it is, and assists the opening force of the door.
A second object is to provide a door lock that does not impair the appearance of the lock body and the seat, and that is free from the possibility of being caught by a protruding hook when a person passes by opening the door.
Furthermore, the third object is to provide a door lock that can easily assist the opening force by simply replacing the handle and the seat and attaching the contact portion to the existing door lock. .

Further, the shaft 93 is engaged with an engaging portion 33 formed on the assist rod 3 as shown in FIG. 9B, and the shaft 93 moves along the elongated hole 53 of the bearing 5 by the rotation of the handle shaft 6. Then, the engaging portion 33 of the assist rod 3 is pushed to rotate the assist rod 3 counterclockwise.

次に、室外側の把手６０と座２０および軸受５などの構成を図３に基づいて説明すると、それらの構成は下記の差異以外は前記室内側の把手１０と座２０および軸受５と同じ構成であるので、その異なる構成についてのみ説明する。
即ち、異なる構成は、前記室内側の軸受５の下部の空間部５８にはアシスト杆３が嵌装されて枢支され、軸９３により押動されて回動するように設けられているのに対し、室外側の軸受５の下部の空間部５８には作動杆７が嵌装され、軸９０が該作動杆７の軸穴７０に挿通され、該軸９０を支点に作動杆７が回動自在に枢支されている点と、室外側の座２０には取付柱２８，２８が固設されるのに対し室内側の座２０には取付用の穴２３，２３が形成されている点である。 Next, the configuration of the outdoor handle 60, the seat 20, and the bearing 5 will be described with reference to FIG. 3. These configurations are the same as those of the indoor handle 10, the seat 20, and the bearing 5 except for the following differences. Therefore, only the different configuration will be described.
That is, a different structure is provided in such a manner that the assist rod 3 is fitted and pivotally supported in the space 58 at the lower part of the indoor bearing 5 and is rotated by being pushed by the shaft 93. On the other hand, the operating rod 7 is fitted in the space 58 below the outdoor bearing 5, the shaft 90 is inserted into the shaft hole 70 of the operating rod 7, and the operating rod 7 rotates around the shaft 90 as a fulcrum.

上記作動杆７の腕部７２は、軸受５の取付基部５４に形成した開口部から突出させ、図４に示すように、錠本体２の下方で扉内に挿入され、および図９（ｂ）に示すように前記室内側のアシスト杆３の腕部３４に係合される。また、作動杆７に形成した係合部７３には、室外側の把手軸６に挿通され保持された作動軸９３が係合し、室外側の把手６０および把手軸６の回動により作動軸９３が作動杆７の係合部７３を押動して、作動杆７を図９（ｂ）に於いて時計方向に回動させる。 The arm portion 72 of the operating rod 7 protrudes from the opening formed in the mounting base portion 54 of the bearing 5, and is inserted into the door below the lock body 2, as shown in FIG. 4, and FIG. 9 (b). Is engaged with the arm portion 34 of the assist rod 3 on the indoor side. Also, the engaging shaft 73 formed on the operating rod 7 engages with the operating shaft 93 inserted and held by the outdoor handle shaft 6, and the operating shaft is rotated by the rotation of the outdoor handle 60 and the handle shaft 6. 93 pushes the engaging portion 73 of the operating rod 7 to rotate the operating rod 7 clockwise in FIG. 9B.

なお、室外側の把手杆８は室内側の把手杆４とは、説明の便宜上符合を変えたが、同じ構成であり、腕部８１は腕部４１に、軸穴８０は軸穴４０に、係合穴８２は係合穴４２にそれぞれ対応する。 The handle 8 on the outdoor side has the same sign as the handle 4 on the indoor side for convenience of explanation, but has the same configuration, the arm 81 being the arm 41, the shaft hole 80 being the shaft hole 40, The engagement holes 82 correspond to the engagement holes 42, respectively.

次に、上記のように構成された本発明の扉錠１の動作について説明する。
図１（ａ）は、閉扉状態を示す平面図で、図７（ａ）は図１（ａ）の状態から室内側の把手１０を角度Ｘだけ扉の開放方向に押して操作した状態で、図７（ｂ）は、把手１０を更に角度Ｙまで押して操作した状態を示す。
また、図９は図１（ａ）の状態の平断面図で、（ａ）は図４のＢ−Ｂ断面図、（ｂ）は同Ｄ−Ｄ断面図であり、図１０（ａ），（ｂ）はそれぞれ図９（ａ），（ｂ）の状態から室内側の把手１０を角度Ｘだけ操作した状態を示し、図１１（ａ），（ｂ）はそれぞれ、把手１０を更に角度Ｙまで操作した状態を示す。 Next, operation | movement of the door lock 1 of this invention comprised as mentioned above is demonstrated.
FIG. 1A is a plan view showing the closed state, and FIG. 7A is a state in which the handle 10 on the indoor side is pushed by an angle X in the door opening direction from the state of FIG. 7 (b) shows a state where the handle 10 is further pushed to the angle Y and operated.
9 is a plan sectional view of the state of FIG. 1A, FIG. 9A is a sectional view taken along line BB in FIG. 4, FIG. 9B is a sectional view taken along line DD, and FIGS. (B) shows a state where the indoor handle 10 is operated by an angle X from the states of FIGS. 9 (a) and 9 (b), and FIGS. 11 (a) and 11 (b) show that the handle 10 is further moved to an angle Y. Shows the state of operation.

まず、室内側の把手１０を角度Ｘだけ押して操作すると、図１０（ａ）に示すように把手１０は把手軸６の軸９１を支点に反時計方向に回動し、把手軸６に設けられた作動軸９２が軸受５に形成された長穴５２に沿って回動する。
該作動軸９２の回動によって、作動軸９２に係合する室内側の把手杆４のＬ字状の係合穴４２の作動軸９２との当接部が、該作動軸９２に押動され、把手杆４が軸９０を支点に図１０（ａ）および図７（ａ）の如く時計方向に回動する。
把手杆４が回動すると、作動軸９２はＬ字状の係合穴４２の当接部から外れた状態となり、当接部に影響されることなく、係合穴４２の長穴部及び軸受５のガイド用の長穴５２に沿って移動可能となる。即ち、把手杆４はそれ以上回動することなく、把手１０の回動が可能である。 First, when the handle 10 on the indoor side is pushed and operated by an angle X, the handle 10 rotates counterclockwise about the shaft 91 of the handle shaft 6 and is provided on the handle shaft 6 as shown in FIG. The actuating shaft 92 rotates along a long hole 52 formed in the bearing 5.
By the rotation of the operation shaft 92, the contact portion of the L-shaped engagement hole 42 of the handle rod 4 on the indoor side that engages with the operation shaft 92 is pushed by the operation shaft 92. The handle bar 4 rotates clockwise about the shaft 90 as shown in FIGS. 10 (a) and 7 (a).
When the handle rod 4 is rotated, the operating shaft 92 is disengaged from the abutting portion of the L-shaped engaging hole 42 and is not affected by the abutting portion. It becomes possible to move along the elongated guide hole 52. That is, the handle rod 4 can be rotated without further rotation.

室内側の把手杆４が回動すると、該把手杆４が係入されている図６の錠本体２に於いて、作動杆１８が把手杆４の腕部４１に押動され時計方向に回動し、連結部１８Ｂを介して連動機構１１を構成する下方の施錠部材１２を反時計方向に回動する。該施錠部材１２の回動によって、連結部１５を介して上方の施錠部材１２が時計方向に回動される。その結果、上下の施錠部材１２の係止部１３とラッチ２Ａの係止溝２Ｂとの係止が解錠され、ラッチ２Ａは解錠され反転可能となり、扉Ｄの開放が可能となる。（該錠本体２およびラッチ２Ａは特開平１１−１４８２５９号公報にも示される公知のものであり、反転作動の詳細説明は省略する。）。 When the handle rod 4 on the indoor side rotates, in the lock body 2 of FIG. 6 in which the handle rod 4 is engaged, the operating rod 18 is pushed by the arm portion 41 of the handle rod 4 and rotates clockwise. The lower locking member 12 constituting the interlocking mechanism 11 is rotated counterclockwise via the connecting portion 18B. As the locking member 12 is rotated, the upper locking member 12 is rotated clockwise through the connecting portion 15. As a result, the locking between the locking portion 13 of the upper and lower locking members 12 and the locking groove 2B of the latch 2A is unlocked, the latch 2A is unlocked and reversible, and the door D can be opened. (The lock body 2 and the latch 2A are well-known ones as disclosed in Japanese Patent Laid-Open No. 11-148259, and detailed description of the reversing operation is omitted.

上記の如く、室内側の把手１０を押して角度Ｘだけ操作してラッチ２Ａを解錠した時のアシスト杆３は図１０（ｂ）の如く、把手軸６に設けた作動軸９３により、その係合部３３が押動され反時計方向に回動し、押動部３２が枠Ｊに設けた当接部３６に当接した状態となっている。 As described above, the assist rod 3 when the latch 2A is unlocked by pushing the handle 10 on the indoor side and operating it by the angle X is shown in FIG. 10 (b) by the operating shaft 93 provided on the handle shaft 6. The joining portion 33 is pushed and rotated counterclockwise, and the pushing portion 32 is in contact with a contact portion 36 provided on the frame J.

上記の状態から、図１１の如く把手１０を更に角度Ｙだけ押して操作すると、図１１（ａ）に示されるように作動軸９２は把手杆４の係合穴４２の長穴部および軸受５の長穴５２に沿って移動するので、把手杆４はそれ以上回動することなく、図１０（ａ）の状態を維持している。一方、アシスト杆３は、把手軸６に設けられた作動軸９３によって係合部３３が押動され図１１（ｂ）の状態にまで回動され、押動部３２が枠に設けた当接部３６を押動し、その反力が、扉Ｄの開放力を助勢（アシスト）するので、把手１０の小さい操作力でも確実に扉Ｄを開放することができる。
尚、この時ラッチ錠２のラッチ２Ａは解錠されているので反転可能であり、図７（ａ）の状態から図７（ｂ）の状態に反転して扉の開放が可能となり、扉Ｄが開放されると、扉Ｄと枠Ｊとの間に隙間Ｐが生じ、その隙間Ｐにより、室内側と室外側とに生じていた気圧差が解消されるので、気圧差により開放が困難な扉Ｄでも、楽に開放することができる。 When the handle 10 is further pushed by an angle Y as shown in FIG. 11 from the above state, the operating shaft 92 is moved into the elongated hole portion of the engagement hole 42 of the handle rod 4 and the bearing 5 as shown in FIG. Since it moves along the long hole 52, the handle rod 4 does not rotate any more and maintains the state of FIG. On the other hand, the assist rod 3 is rotated to the state shown in FIG. 11B by the engaging portion 33 being pushed by the operating shaft 93 provided on the handle shaft 6, and the pushing portion 32 is in contact with the frame. Since the portion 36 is pushed and the reaction force assists the opening force of the door D, the door D can be reliably opened even with a small operating force of the handle 10.
At this time, since the latch 2A of the latch lock 2 is unlocked, the latch 2A can be reversed, and the door can be opened by reversing from the state of FIG. 7 (a) to the state of FIG. 7 (b). Is opened, a gap P is generated between the door D and the frame J, and the gap P eliminates the atmospheric pressure difference generated between the indoor side and the outdoor side. Therefore, the opening is difficult due to the atmospheric pressure difference. Even the door D can be opened easily.

次に、図８と図１２および図１３に基づいて室外側の把手６０を操作した時の動作を説明する。
図８（ａ）は把手６０を扉Ｄの開放方向に角度Ｘだけ引いて操作した状態の平面図で、図１２（ａ）はその状態に於ける図４のＣ−Ｃ断面図、（ｂ）は同Ｅ−Ｅ断面図である。 Next, an operation when the outdoor handle 60 is operated will be described with reference to FIGS. 8, 12, and 13.
