Some door closers are generally composed of a closer body attached to one of the front and rear surfaces of a door and two rotating arms linked to the closer body and the door frame (for example, Patent Document 1). And one end of the pivot arm is connected to the closer body accommodated in the upper end portion of the door, and the other end is in a recess in the upper lower surface of the door frame. There is a so-called conshield door closer (see, for example, Patent Document 2) slidably linked to a guide rail accommodated in the housing.
JP-A-11-336406 JP 2004-19346 A

上記特許文献1に記載されているものにおいては、クローザ本体や2本の回動アームがドアの前後面より大きく露呈して取付けられているので、体裁を重要視する間仕切り等のガラスドアに取付けるのには不向きである。   In the thing described in the said patent document 1, since the closer main body and two rotation arms are exposed and attached larger than the front-and-back surface of a door, it attaches to glass doors, such as a partition which attaches importance to appearance. Not suitable for.

特許文献2に記載のコンシールドドアクローザは、クローザ本体とガイドレールは、それぞれ、ドアとドア枠内に収容され、回動アームのみが外部に露出する構造となっているので、上記特許文献1のドアクローザに比して体裁がよい。
しかし、上記のような間仕切り等のガラスドアに、コンシールドドアクローザを取付けようとすると、板厚の薄いガラスドアにクローザ本体を収容することができないため、それの取付け方法が課題となっている。
また、ガラスドアが閉じられているときに、回動アームが外部より露見されるとともに、ガイドレールの一部も、透明なガラス板から透けて見えるようになるので、それらをいかに体裁よく覆いうるようにするかも、課題の一つとなっている。
In the conshielded door closer described in Patent Document 2, the closer body and the guide rail are housed in the door and the door frame, respectively, and only the rotating arm is exposed to the outside. It looks better than a door closer.
However, if the concealed door closer is to be attached to a glass door such as a partition as described above, the closer main body cannot be accommodated in the glass door having a thin plate thickness.
In addition, when the glass door is closed, the rotating arm is exposed from the outside, and part of the guide rail can be seen through the transparent glass plate, so that it can be covered nicely. It may be one of the issues.

本発明は、上記課題に鑑みてなされたもので、ガラスドアに、ドアクローザを体裁よく取付けうるようにした取付構造を提供することを目的としている。   The present invention has been made in view of the above problems, and an object of the present invention is to provide an attachment structure that allows a door closer to be attached to a glass door.

本発明によると、上記課題は、次の各項のようにして解決される。
(1)ドア枠の一側部に側端部が開閉可能に枢着されたドアの上端部に、クローザ本体を取付け、かつ前記ドア枠の上部に、前記クローザ本体の上面より突出する回動軸に基端部が固着された回動アームにおける先端部のスライダを、左右方向に摺動可能に嵌合し、前記ドアを常時閉じる方向に付勢するようにしたドアクローザの取付構造において、前記ドアを、少なくとも上部がガラス板よりなるガラスドアとし、前記クローザ本体を、前記ガラス板の上端部の前面側に配設される前部カバー部材と、同じく後面側に配設される後部カバー部材との対向面のいずれか一方に取付けるとともに、前記クローザ本体を、ガラス板の上端部に設けた凹部に嵌合し、前記前部カバー部材と後部カバー部材とによりガラス板の上端部を挟持するようにして、これら前後のカバー部材同士を互いに固定する。
According to the present invention, the above-mentioned problems are solved as follows.
(1) A closer main body is attached to the upper end of a door pivotally attached to one side of the door frame so that the side end can be opened and closed, and the upper part of the door frame projects from the upper surface of the closer main body. In the door closer mounting structure in which the slider at the distal end of the rotating arm having the base end fixed to the shaft is slidably fitted in the left-right direction, and the door is always urged in the closing direction. The door is a glass door having at least an upper portion made of a glass plate, and the closer main body is disposed on the front side of the upper end portion of the glass plate, and the rear cover member is also disposed on the rear side. The closer body is fitted into a recess provided in the upper end portion of the glass plate, and the upper end portion of the glass plate is sandwiched between the front cover member and the rear cover member. like Te to secure these front and rear cover members together with each other.

このような構成とすると、ドアクローザのクローザ本体を、ガラス板の前面側と後面側に配設される前部カバー部材と後部カバー部材とのいずれか一方に取付け、かつガラス板の上端部に設けた凹部にクローザ本体を嵌合して、前後のカバー部材同士を固定しているので、ガラス板の厚さが比較的薄いものであっても、その前面または後面からのドアクローザの突出寸法を小さくすることができ、ガラスドアとしての体裁がよくなる。
また、クローザ本体は、前後のカバー部材により覆われ、前後方向より目隠しされるで、クローザ取付部の見栄えが向上する。
With such a configuration, the closer body of the door closer is attached to one of the front cover member and the rear cover member disposed on the front side and the rear side of the glass plate, and provided on the upper end portion of the glass plate. Since the front and back cover members are fixed to each other by fitting the closer body into the recessed portion, even if the thickness of the glass plate is relatively thin, the protrusion size of the door closer from its front or rear surface is reduced. The appearance as a glass door can be improved.
Further, the closer body is covered with the front and rear cover members and is hidden from the front and rear direction, so that the appearance of the closer attaching portion is improved.

(2)上記(1)項において、前部カバー部材と後部カバー部材の左右寸法を、ドア枠における上部の横杆の下面に設けられ、かつスライダを左右方向に摺動可能に案内するガイド溝の左右寸法とほぼ等しくするとともに、ガラスドアの開き方向側に配設される前部カバー部材または後部カバー部材により、回動アームを前方または後方より覆うようにする。 (2) In the above paragraph (1), the left and right dimensions of the front cover member and the rear cover member are provided on the lower surface of the upper side of the door frame and guide the slider slidably in the left-right direction. The rotation arm is covered from the front or rear by a front cover member or a rear cover member disposed on the opening direction side of the glass door.

このような構成とすると、ドア枠における横杆の上部に設けたガイド溝が、ガラス板の前後方向から透けて見えにくくなるとともに、回動アームも、前後いずれか一方のカバー部材により覆われて目隠しされるので、ガラスドアとしての体裁がさらによくなる。   With such a configuration, the guide groove provided on the upper side of the horizontal frame in the door frame is difficult to see through from the front and rear direction of the glass plate, and the rotating arm is also covered by either the front or rear cover member. Because it is blindfolded, the appearance as a glass door is further improved.

(3)上記(1)または(2)項において、前部カバー部材と後部カバー部材との間に、中間ブラケットを挟入し、この中間ブラケットと、前部カバー部材と後部カバー部材とのいずれか一方とを、ガラス板を挟持するようにして互いに締付手段により結合するとともに、前部カバー部材と後部カバー部材とのいずれか他方を、前記中間ブラケットに、これを覆うようにしてねじ止めする。 (3) In the above item (1) or (2), an intermediate bracket is interposed between the front cover member and the rear cover member, and any of the intermediate bracket, the front cover member, and the rear cover member is inserted. And the other one of the front cover member and the rear cover member is screwed to the intermediate bracket so as to cover the glass plate. To do.

このような構成とすると、前後のカバー部材を、中間ブラケットを介して容易に固定しうるとともに、前後のカバー部材を直接固定するねじ等が不要となるので、ねじ等の頭部が、前後のカバー部材の前面または後面より露呈するのが少なくなり、見栄えがよくなる。   With such a configuration, the front and rear cover members can be easily fixed via the intermediate bracket, and the screws and the like for directly fixing the front and rear cover members are not necessary. It is less exposed than the front or rear surface of the cover member, and the appearance is improved.

(4)上記(3)項において、締付手段を、前部カバー部材または後部カバー部材におけるガラス板との対向面に固着され、ガラス板と中間ブラケットとを貫通して前後いずれか一方に突出する複数のスタッドボルトと、このスタッドボルトの突出端部に螺合されたナットとからなるものとする。 (4) In the above item (3), the tightening means is fixed to the surface of the front cover member or the rear cover member facing the glass plate, penetrates the glass plate and the intermediate bracket, and protrudes forward or backward. And a plurality of stud bolts and nuts screwed to the protruding end portions of the stud bolts.

このような構成とすると、スタッドボルトとナットよりなる締付手段が外部に露呈しないので、見栄えがより向上する。   With such a configuration, the fastening means including the stud bolt and the nut is not exposed to the outside, so that the appearance is further improved.

本発明によれば、ドアクローザのクローザ本体を、ガラス板の前面側と後面側に配設される前部カバー部材と後部カバー部材とのいずれか一方に取付け、かつガラス板の上端部に設けた凹部にクローザ本体を嵌合して、前後のカバー部材同士を固定しているので、ガラス板の厚さが比較的薄いものであっても、その前面または後面からのドアクローザの突出寸法を小さくすることができ、ガラスドアとしての体裁がよくなる。   According to the present invention, the closer body of the door closer is attached to one of the front cover member and the rear cover member disposed on the front side and the rear side of the glass plate, and is provided on the upper end portion of the glass plate. Since the front and back cover members are fixed to each other by fitting the closer body into the recess, even if the glass plate is relatively thin, the projection size of the door closer from the front or rear surface is reduced. And the appearance as a glass door is improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a main part of a partition provided with an embodiment of the present invention, FIG. 2 is an enlarged exploded perspective view of a glass door and members attached thereto, and FIG. 3 is an enlarged view of line III-III in FIG. The cross-sectional plan view and FIG. 4 are similarly the IV-IV line enlarged cross-sectional plan view.

床面に立設された、多数のガラスパネル1よりなる間仕切り2の一部に形成された出入口3には、左右1対の縦杆4、4と、両縦杆4の上端部同士を連結している横杆5とからなる正面視門型のドア枠6が固着され、このドア枠6により囲まれた内方には、ガラスドア7が、その右側端部に取付けた把手8を操作することにより、左側端部を中心として前方に開閉しうるように装着されている。   A pair of left and right vertical gutters 4 and 4 and the upper ends of both vertical gutters 4 are connected to an entrance / exit 3 formed on a part of a partition 2 made up of a number of glass panels 1 erected on the floor surface. A front door-type door frame 6 composed of a horizontal reed 5 is fixed, and a glass door 7 operates a handle 8 attached to the right end of the door frame 6 inside the door frame 6. By doing so, it is mounted so that it can be opened and closed forward about the left end.

ガラスドア7における透明なガラス板9は、例えば厚さが10〜15mm程度の強化ガラスよりなっている。
左右の縦枠4及び横枠5の前後寸法は、ガラス板9の板厚よりも十分に大とされ、それらの後端部の内側面には、ガラスドア7の後方への移動を阻止するストッパ部10が、内向きに突設されている。各ストッパ部10の前面に長手方向に向かって形成されたあり溝状断面の嵌合溝11には、ガラスドア7の周縁部後面が当接する、ゴムまたはエラストマーよりなる緩衝材12(図2においては図示略)の後端部が嵌合されている(図3参照)。
The transparent glass plate 9 in the glass door 7 is made of tempered glass having a thickness of about 10 to 15 mm, for example.
The front and rear dimensions of the left and right vertical frames 4 and the horizontal frame 5 are sufficiently larger than the thickness of the glass plate 9, and the rearward movement of the glass door 7 is prevented on the inner side surfaces of the rear ends thereof. The stopper portion 10 protrudes inward. A cushioning material 12 made of rubber or elastomer (in FIG. 2) with which the rear surface of the peripheral edge of the glass door 7 comes into contact with the fitting groove 11 having a groove-like cross section formed in the longitudinal direction on the front surface of each stopper portion 10. Is a rear end portion (see FIG. 3).

ガラス板9の左側端部の前面と後面には、それぞれ、ガラス板9の上下寸法よりも若干短寸のアルミニウムまたは硬質合成樹脂等よりなるガラス保持部材13と補強部材14とが、次のようにして取付けられている。
図2及び図3に示すように、前面側のガラス保持部材13は、後面が垂直面をなす所要幅の基部13a の外側端部に、左側端面が垂直面をなす前向膨出部13bを連設したものよりなり、前向膨出部13bの前端部を除いた内部は、中空とされている。
A glass holding member 13 and a reinforcing member 14 made of aluminum, hard synthetic resin, or the like that is slightly shorter than the vertical dimension of the glass plate 9 are respectively provided on the front and rear surfaces of the left end portion of the glass plate 9 as follows. Is installed.
As shown in FIGS. 2 and 3, the front side glass holding member 13 has a forward bulging portion 13b whose left end surface forms a vertical surface at the outer end portion of a base portion 13a having a required width whose rear surface forms a vertical surface. It consists of what was provided continuously, and the inside except the front-end part of the front bulging part 13b is made hollow.

前向膨出部13bの前端部には、上下両方向に開口する軸孔15が貫設され、基部13a の後面の左側縁部には、位置決め用の突片13cが、後向きに突設されている。   A shaft hole 15 that opens in both the upper and lower directions penetrates through the front end of the forward bulging portion 13b, and a positioning protrusion 13c projects rearward from the left side edge of the rear surface of the base portion 13a. Yes.

後面側の補強部材14は、後面中央部に後向膨出部14aを有する縦長の平板状をなし、後向膨出部14aには、後方と上下両方向に開口する保持溝16が、上下方向の全長に亘って形成されている。   The reinforcing member 14 on the rear surface side has a vertically long flat plate shape having a rearward bulging portion 14a at the center of the rear surface. The rearwardly bulging portion 14a has a holding groove 16 that opens in both the rear and upper and lower directions. Is formed over the entire length.

ガラス保持部材13と補強部材14を、ガラス板9に取付けるには、それら互いの対向面間に緩衝シート17、17を挟入して、ガラス保持部材13と補強部材14を、ガラス板9の左側端部の前後両面に当接させる。この際、ガラス保持部材13は、その突片13cをガラス板9の側端面に当接させることにより、左右方向に位置決めすることができる。   In order to attach the glass holding member 13 and the reinforcing member 14 to the glass plate 9, the buffer sheets 17 and 17 are sandwiched between the opposing surfaces of the glass holding member 13 and the reinforcing member 14. It abuts on both the front and back sides of the left end. At this time, the glass holding member 13 can be positioned in the left-right direction by bringing the protruding piece 13 c into contact with the side end surface of the glass plate 9.

ついで、補強部材14に穿設された上下複数の取付孔18に挿入した締付けねじである皿ねじ19を、ガラス板9と前後の緩衝シート17とに設けた通孔20に挿通して、ガラス保持部材13の基部13a に設けためねじ孔21に螺合して、強く締め付ける。これにより、ガラス板9の左側端部は、ガラス保持部材13と補強部材14とにより挟持され、その部分が補強されることにより、ガラス板9が厚さ方向に撓んだり、反ったりするのが防止される。   Next, a countersunk screw 19, which is a tightening screw inserted into a plurality of upper and lower mounting holes 18 drilled in the reinforcing member 14, is inserted into a through-hole 20 provided in the glass plate 9 and the front and rear shock-absorbing sheets 17. Since it is provided in the base portion 13a of the holding member 13, it is screwed into the screw hole 21 and tightened strongly. Thereby, the left end part of the glass plate 9 is clamped by the glass holding member 13 and the reinforcing member 14, and the glass plate 9 bends or warps in the thickness direction when the portion is reinforced. Is prevented.

補強部材14の後面には、合成樹脂製のカバー部材22が、その前面に突設された上下複数の弾性係合片23を、補強部材14の保持溝16に押し込んで係合させることにより、着脱可能に取付けられている。   On the rear surface of the reinforcing member 14, a synthetic resin cover member 22 pushes and engages a plurality of upper and lower elastic engagement pieces 23 projecting from the front surface of the reinforcing member 14 into the holding groove 16 of the reinforcing member 14. Removably attached.

図4及び図5に示すように、ドア枠6における左側の縦杆4の下端部の内側面には、正面視L字状断面のドア支持金具24における垂直片24aが、複数の皿ねじ25により固定されている。ドア支持金具24の内向片24bには、上方を向くヒンジピン26が、その下端に連設された若干小径のおねじ軸27を、内向片24bに穿設した通孔28に挿通し、突出端部に2個のナット29、29を螺合することにより、回動不能に固着されている。30は、おねじ軸27の下端部に差し込まれた、ナット29の緩み止めを防止するピンである。   As shown in FIGS. 4 and 5, the vertical piece 24 a of the door support bracket 24 having an L-shaped cross section in front view is provided on the inner surface of the lower end portion of the left vertical shaft 4 in the door frame 6. It is fixed by. A hinge pin 26 facing upward is inserted into an inward piece 24b of the door support bracket 24, and a slightly small-diameter male screw shaft 27 connected to the lower end thereof is inserted into a through-hole 28 formed in the inward piece 24b, and a protruding end. The two nuts 29 and 29 are screwed together to be fixed so as not to rotate. Reference numeral 30 denotes a pin that is inserted into the lower end of the male screw shaft 27 and prevents the nut 29 from being loosened.

このようにして、ヒンジピン26をドア支持金具24に固着すると、ヒンジピン26が摩耗した際等に、それのみを交換することが可能となるが、ヒンジピン26を、溶接により内向片24bに固着することもある。   When the hinge pin 26 is fixed to the door support bracket 24 in this way, it is possible to replace only the hinge pin 26 when it is worn. However, the hinge pin 26 is fixed to the inward piece 24b by welding. There is also.

ガラス保持部材13における前向膨出部13bの軸孔15の下端部には、鍔付きブッシュ31が下方より圧嵌されており、この鍔付きブッシュ31に、上記ヒンジピン26を、スラストワッシャ32を介して回動可能に嵌合することにより、ガラスドア7の左側の側端下部が、ドア支持金具24の内向片24bにより受支され、かつヒンジピン26を中心として前方に回動することができる。   A bushed bush 31 is press-fit from below to the lower end of the shaft hole 15 of the forward bulging portion 13b of the glass holding member 13. The hinge pin 26 and the thrust washer 32 are fitted to the bushed bush 31. The left side end lower portion of the glass door 7 is supported by the inward piece 24b of the door support bracket 24 and can be rotated forward about the hinge pin 26. .

図6に示すように、正面視倒立L字状断面をなす上側のドア支持金具33の内向片33aには、上記ヒンジピン26と同形のヒンジピン34が、その上端に連設されたおねじ軸35にナット29、29を螺合することにより、回動不能に下向きに固着されている。このヒンジピン34を、前向膨出部13bの軸孔15の上端部に上方より圧嵌した、上記と同様の鍔付きブッシュ31に、スラストワッシャ32を介して上方より嵌合したのち、ドア支持金具33の垂直片33bを、左側の縦杆4の上端部の内側面に、複数の皿ねじ25により固着することにより、ガラスドア7の側端上部が、ヒンジピン34を中心として前方に回動可能に支持される。   As shown in FIG. 6, a hinge pin 34 having the same shape as the hinge pin 26 is connected to the upper end of the inwardly-moving piece 33a of the upper door support fitting 33 having an inverted L-shaped cross section when viewed from the front. The nuts 29 and 29 are screwed to each other so that they cannot be rotated and are fixed downward. The hinge pin 34 is fitted from above to a bushed bush 31 similar to the above that is press-fitted to the upper end of the shaft hole 15 of the forward bulging portion 13b, and then supported by the door. The vertical piece 33b of the metal fitting 33 is fixed to the inner surface of the upper end portion of the left vertical shaft 4 with a plurality of countersunk screws 25 so that the upper side end of the glass door 7 rotates forward about the hinge pin 34. Supported as possible.

上記実施形態のように、ガラスドア7には、従来のような四方枠はなく、ヒンジピン26、34が取付けられるガラス板9の一側端部のみに、ガラス保持部材13と補強部材14を取付けて構成されているので、透明なガラスの領域が広くなり、かつデザイン的に自由度も大きくなるため、ガラスドア7としての見栄えが向上する。   As in the above embodiment, the glass door 7 does not have a conventional four-sided frame, and the glass holding member 13 and the reinforcing member 14 are attached only to one end of the glass plate 9 to which the hinge pins 26 and 34 are attached. Thus, the transparent glass area is widened and the degree of freedom in design is increased, so that the appearance of the glass door 7 is improved.

また、ガラス板9の側端部がガラス保持部材13と補強部材14とにより補強され、かつガラス保持部材13の上下両端部が、ドア枠6の縦杆4に固定したドア支持金具33、24のヒンジピン34、26により回動可能に支持されているので、厚さ及び高さの比較的大きな重量のあるガラス板9であっても、それを変形させたりすることなく、ガラスドア7全体をヒンジピン34、26を介して安定よく取付けることができる。   Further, the door support fittings 33 and 24 in which the side end portions of the glass plate 9 are reinforced by the glass holding member 13 and the reinforcing member 14 and the upper and lower end portions of the glass holding member 13 are fixed to the vertical rod 4 of the door frame 6. Since the glass plate 9 having a relatively large thickness and height is supported by the hinge pins 34 and 26, the entire glass door 7 is not deformed. It can be stably attached via the hinge pins 34 and 26.

さらに、ガラス保持部材13における前向膨出部13bが、上下のヒンジピン34、26により支持され、回動中心が、ガラスドア7よりも前方に位置しているので、ガラスドア7を開く際に、その側端面が縦杆4の内側面より離間するようになり、従って、ガラスドア7と縦杆4との間に指や異物が挟まれることがなくなる。   Furthermore, since the forward bulging portion 13b of the glass holding member 13 is supported by the upper and lower hinge pins 34 and 26 and the center of rotation is located in front of the glass door 7, when the glass door 7 is opened. Therefore, the side end face is separated from the inner side surface of the vertical gutter 4, and accordingly, fingers and foreign substances are not sandwiched between the glass door 7 and the vertical gutter 4.

上記実施形態では、ガラス保持部材13と補強部材14とを別体としてあるが、図7に示すように、ガラス保持部材13の突片13cを後向きに延出することにより、ガラス板9の側端面を覆う連結片13c'を形成し、これを、補強部材14と結合して、ガラス保持部材13と補強部材14とを一体的に連結してもよい。このようにすると、ガラス板9の側端部がより強固に補強される。   In the said embodiment, although the glass holding member 13 and the reinforcement member 14 are made into a different body, as shown in FIG. 7, by extending the protrusion 13c of the glass holding member 13 backward, the glass plate 9 side A connecting piece 13c ′ covering the end surface may be formed, and this may be coupled to the reinforcing member 14 to integrally connect the glass holding member 13 and the reinforcing member 14. If it does in this way, the side edge part of the glass plate 9 will be reinforced more firmly.

また、上記実施形態では、ガラス保持部材13の上下の端部を、ヒンジピン34、26により支持するようにしたが、ガラス板9が比較的軽量のものであるときには、上下複数の蝶番等を、ガラス保持部材13の外側面に取付けて、これを支持することもある。   In the above embodiment, the upper and lower ends of the glass holding member 13 are supported by the hinge pins 34 and 26. However, when the glass plate 9 is relatively light, a plurality of upper and lower hinges, etc. It may be attached to the outer surface of the glass holding member 13 to support it.

さらに、補強部材14、及びその後面に止着したカバー部材22は省略することもある。
ガラスドア7を後方に開閉するようにした際には、ガラス保持部材13と補強部材14とを、ガラス板9の前後面に、前後反対として固定すればよい。
Furthermore, the reinforcing member 14 and the cover member 22 fixed to the rear surface may be omitted.
When the glass door 7 is opened and closed rearward, the glass holding member 13 and the reinforcing member 14 may be fixed to the front and rear surfaces of the glass plate 9 in the opposite direction.

ガラスドア7の上端部には、ドアクローザ36が、次のようにして取付けられている。
