上記従来の扉用ロックハンドル装置においては、扉を閉鎖した状態では、受金体が扉の裏側に隠れてしまうので、密閉状態で扉の締め込み具合を調整することができない。このため、スチームオーブンなどの調理機器において、機器を稼働させて蒸気漏れを確認しながら扉の締め込み具合を調整することができない。
したがって、この出願に係る発明は、密閉状態で扉の締め込み具合を調整することができる扉用ロックハンドル装置を提供することを課題としている。
In the above-described conventional door lock handle device, when the door is closed, the metal receiver is hidden behind the door, and thus the degree of tightening of the door cannot be adjusted in a sealed state. For this reason, in a cooking appliance such as a steam oven, it is not possible to adjust the tightening condition of the door while operating the appliance and checking for steam leakage.
Accordingly, an object of the invention according to this application is to provide a door lock handle device capable of adjusting the degree of tightening of the door in a sealed state.

上記課題を解決するため、この出願に係る発明においては、扉に固着される固定受座と、固定受座に一定角度離れた非ロック位置とロック位置の間で正逆回転可能に嵌挿される操作ハンドルと、基端側が操作ハンドルに相対回転不可能に支持され扉を貫通して先端側が扉の裏側への突出するハンドル軸と、筐体に取り付けられる受金体と、ハンドル軸の先端側に固着され操作ハンドルのロック位置において受金体の裏側に係合し非ロック位置において受金体から外れる掛金体とを具備する扉のロックハンドル装置において、ハンドル軸には、軸本体と、この軸本体に同心的に螺合された調整ボルトとを具備させる。軸本体は、扉の裏側への突出長さを変更できるように、操作ハンドルに対して一定範囲で軸線方向に進退自在、かつ突出方向に付勢して組み込む。調整ボルトには、操作ハンドルに回転可能に受け止められ、扉の外側から回転操作用工具を係合可能な頭部と、頭部から延出して軸本体に螺合する軸部とを具備させる。扉の外側から調整ボルトを回転操作することにより、軸本体を扉に対して軸線方向へ移動して、受金体に対する掛金体の位置を調整可能に構成する。   In order to solve the above-mentioned problem, in the invention according to this application, the fixed receiving seat fixed to the door and the fixed receiving seat are inserted so as to be able to rotate forward and backward between a non-locking position and a locking position separated by a certain angle. An operation handle, a handle shaft whose base end side is supported by the operation handle so as not to rotate relative to the operation handle, penetrates the door, and the front end side protrudes to the back side of the door, a metal receiver attached to the housing, and a distal end side of the handle shaft In the door lock handle device, the handle shaft includes a shaft main body, the shaft main body, and the handle body. And an adjusting bolt concentrically screwed to the shaft body. The shaft body is incorporated so that it can be moved back and forth in the axial direction within a certain range with respect to the operation handle and urged in the protruding direction so that the protruding length to the back side of the door can be changed. The adjustment bolt includes a head that is rotatably received by the operation handle and can be engaged with a rotary operation tool from the outside of the door, and a shaft that extends from the head and is screwed into the shaft body. By rotating the adjustment bolt from the outside of the door, the shaft main body is moved in the axial direction with respect to the door so that the position of the latch body relative to the receiving body can be adjusted.

この出願に係る発明の装置によれば、扉の外側から調整ボルトを回転操作することにより、軸本体を扉に対して軸線方向へ移動して、受金体に対する掛金体の位置を調整可能であるから、密閉状態で扉の締め込み具合を調整することができる。   According to the device of the invention of this application, by rotating the adjustment bolt from the outside of the door, the shaft body can be moved in the axial direction with respect to the door, and the position of the latch body relative to the metal receiver can be adjusted. Therefore, it is possible to adjust the tightness of the door in a sealed state.

As shown in FIG. 3, a bearing hole 8 that penetrates the flange portion 6 and the sleeve 7 is formed in the fixed seat 2. The bearing hole 8 has a large-diameter spring receiving portion 8b that opens to the front side with an intermediate step portion 8a as a boundary, and a small-diameter portion 8c that opens backward through the sleeve 7. The sleeve 7 passes through a through hole 32 formed in the front-rear direction of the door 31. The fixed seat 2 is fixed to the door 31 with bolts 9. As shown in FIG. 6, six detent grooves 10 are radially formed on the front surface of the flange portion 6 at intervals of 60 °.

図3に示すように、操作ハンドル3は、根元部11が、固定受座2の鍔部6に正逆回転可能に嵌挿される。操作ハンドル3の回転範囲は、ボルト12によって右又は左のいずれか一方向に60°に限定される。すなわち、図4に示すように、ボルト12は、頭部を固定受座2の円弧状溝13内に摺動自在に保持されて、同溝内に形成された円弧状長孔14を自在に貫通し、操作ハンドルの根元部11に螺合している。根元部11に対するボルト12の螺合位置を変更することにより、操作ハンドル3の回転方向を右又は左に変更することができる。   As shown in FIG. 3, the operation handle 3 has a root portion 11 fitted into the flange portion 6 of the fixed seat 2 so as to be rotatable forward and backward. The rotation range of the operation handle 3 is limited to 60 ° in either the right or left direction by the bolt 12. That is, as shown in FIG. 4, the bolt 12 has its head slidably held in the arc-shaped groove 13 of the fixed seat 2 so that the arc-shaped long hole 14 formed in the groove can freely move. It penetrates and is screwed into the root portion 11 of the operation handle. By changing the screwing position of the bolt 12 with respect to the root portion 11, the rotation direction of the operation handle 3 can be changed to the right or left.

図3に示すように、デテントピン24は、ばね25で突出方向に付勢されて操作ハンドルの根元部11に保持され、頭部が固定受座2のデテント溝10に落ち込むことにより、操作ハンドル3をロック位置又は非ロック位置に保持する。
操作ハンドルの根元部11には、固定受座2の軸受け孔8と同心の軸受け孔15が貫通する。軸受け孔15は、軸受け孔8のばね受け部8bに連続する大径のばね受け部15aと、段部15bを介してばね受け部15aに連続する角孔部15cとを有する。角孔部15cは、根元部11の前面側に開口する凹部16内に開放している。凹部16の開口は、着脱自在のキャップ17で閉じられる。
As shown in FIG. 3, the detent pin 24 is urged in the protruding direction by a spring 25 and is held by the root portion 11 of the operation handle, and the head falls into the detent groove 10 of the fixed seat 2, thereby Is held in the locked or unlocked position.
A bearing hole 15 concentric with the bearing hole 8 of the fixed seat 2 passes through the root portion 11 of the operation handle. The bearing hole 15 includes a large-diameter spring receiving portion 15a that is continuous with the spring receiving portion 8b of the bearing hole 8, and a square hole portion 15c that is continuous with the spring receiving portion 15a via a step portion 15b. The square hole portion 15 c is open in a recess 16 that opens to the front side of the root portion 11. The opening of the recess 16 is closed by a removable cap 17.

ハンドル軸4は、先端側の軸本体18と、この軸本体18に同心的に螺合される基端側の調整ボルト19とを具備する。   The handle shaft 4 includes a shaft body 18 on the distal end side, and an adjustment bolt 19 on the proximal end side that is concentrically screwed to the shaft body 18.

軸本体18は、固定受座2のスリーブ7を回転自在に貫通して扉31の裏側へ突出する円柱部18aと、フランジ18bを介して円柱部18aに同心的に連続する角軸部18cとを有する。   The shaft body 18 includes a columnar portion 18a that rotatably passes through the sleeve 7 of the fixed seat 2 and protrudes to the back side of the door 31, and an angular shaft portion 18c that concentrically continues to the columnar portion 18a via a flange 18b. Have

角軸部18cは、ばね受け部8b,15aを貫通して角孔部15cに軸方向相対移動自在に嵌合している。角軸部18cには、軸方向にねじ穴20が形成される。角軸部18cの外周にはばね21が外挿され、ばね受け部8b,15a内に収容される。ばね21は、一端がフランジ18bに、他端が段部15bにそれぞれ係止され、常時軸本体18を先端側へ付勢している。   The square shaft portion 18c passes through the spring receiving portions 8b and 15a and is fitted to the square hole portion 15c so as to be relatively movable in the axial direction. A screw hole 20 is formed in the angular shaft portion 18c in the axial direction. A spring 21 is extrapolated on the outer periphery of the angular shaft portion 18c and is accommodated in the spring receiving portions 8b and 15a. One end of the spring 21 is locked to the flange 18b and the other end is locked to the step portion 15b, and always urges the shaft body 18 toward the tip end side.

調整ボルト19は、頭部19aと軸部19bとを有し、頭部19aが凹部16内に配置され、座金22を介在させて軸部19bが角孔部15cに挿通される。軸部19bの先端部は、軸本体18のねじ穴20に螺合される。したがって、凹部16のキャップ17を外し、頭部19aにレンチを掛け、調整ボルト19を回転操作することができる。そして、ねじ穴20に対する調整ボルト19の螺合深さを調整することにより、ばね21を伸縮させつつ、軸本体18の扉31からの突出長さを変更することができる。   The adjustment bolt 19 has a head portion 19a and a shaft portion 19b. The head portion 19a is disposed in the recess 16, and the shaft portion 19b is inserted into the square hole portion 15c with a washer 22 interposed therebetween. The distal end portion of the shaft portion 19 b is screwed into the screw hole 20 of the shaft body 18. Accordingly, the cap 17 of the recess 16 can be removed, a wrench can be hung on the head 19a, and the adjustment bolt 19 can be rotated. Then, by adjusting the screwing depth of the adjustment bolt 19 with respect to the screw hole 20, the length of protrusion of the shaft body 18 from the door 31 can be changed while the spring 21 is expanded and contracted.

掛金体5は、軸本体18の先端部に固着される。掛金体5は、図1に実線で示すように、操作ハンドル3が上下方向延びるように配置されるロック位置において受金体23の裏側に係合し、仮想線で示すように、60°回転した非ロック位置において受金体23から外れる。   The latch body 5 is fixed to the tip of the shaft body 18. As shown by a solid line in FIG. 1, the latch body 5 engages with the back side of the metal receiver 23 at a locked position where the operation handle 3 is arranged to extend in the vertical direction, and rotates 60 ° as indicated by a virtual line. In the unlocked position, it is detached from the metal receiver 23.

例えば、上記実施形態のロックハンドル装置を適用したスチームオーブンの扉において、締め込み具合を調整する場合には、扉31を閉じて、操作ハンドル3をロック位置に配置し、オーブンを稼働させた状態で、キャップ17を外し、レンチを調整ボルト19の頭部19aに掛け、これを例えば右回転させると、これに螺合する軸本体18が、ばね21を圧縮しつつ図3において左方へ引き寄せられ、これにより掛金体5が左方へ移動するので、受金体23との係合がより深くなり、扉31の密閉度を増すことができる。逆に調整ボルト19を左回転させると、軸本体18が、ばね21を伸ばしつつ掛金体5と共に、図3において右方へ移動するので、受金体23との係合が浅くなり、扉31の密閉度を下げることができる。いずれの方向への調整も、扉31を閉じた状態で、スチームの噴出具合等を確認しながら的確に行うことができる。従来のように、調整のたびに扉を開き、オーブンを再加熱する必要がない。   For example, in a steam oven door to which the lock handle device of the above embodiment is applied, when adjusting the tightening condition, the door 31 is closed, the operation handle 3 is placed at the lock position, and the oven is operated. When the cap 17 is removed and a wrench is hung on the head 19a of the adjusting bolt 19 and is rotated, for example, to the right, the shaft body 18 screwed with the wrench draws the spring 21 toward the left in FIG. As a result, the latch body 5 moves to the left, so that the engagement with the metal receiver 23 becomes deeper and the sealing degree of the door 31 can be increased. Conversely, when the adjustment bolt 19 is rotated counterclockwise, the shaft body 18 moves to the right in FIG. 3 together with the latch body 5 while extending the spring 21, so that the engagement with the metal receiver 23 becomes shallow, and the door 31. The degree of sealing can be lowered. Adjustment in any direction can be performed accurately while confirming the degree of steam ejection, etc. with the door 31 closed. As in the prior art, it is not necessary to open the door and reheat the oven for each adjustment.
