本発明によると、カバーの取り付けが容易でかつ扉を傷つけることなくカバーを取り外すことができる丸座および丸座セットを提供することができる。   According to the present invention, it is possible to provide a round seat and a round seat set in which the cover can be easily attached and the cover can be removed without damaging the door.

図１は扉３に取り付けられた丸座１の斜視図、図２は図１における丸座１の拡大斜視図、図３は丸座１の正面図、図４は図３における左側面図、図５は丸座１の平面図、図６はカバー２の裏面図、図７は図６におけるＡ−Ａ矢視断面図である。
丸座１は、本体５および２つのクリップ部（第１クリップ部６および第２クリップ部７）からなる。
本体５は、形状が径に比べて高さが低い円柱状であって、その軸心を断面が円形の孔である角芯挿通孔１１が貫通している。本体５の周面（側面）１２には、１８０度の間隔をあけて２つの係止部１３，１３が設けられている。 1 is a perspective view of the round seat 1 attached to the door 3, FIG. 2 is an enlarged perspective view of the round seat 1 in FIG. 1, FIG. 3 is a front view of the round seat 1, FIG. 4 is a left side view in FIG. 5 is a plan view of the circular seat 1, FIG. 6 is a back view of the cover 2, and FIG. 7 is a cross-sectional view taken along line AA in FIG.
The round seat 1 includes a main body 5 and two clip portions (a first clip portion 6 and a second clip portion 7).
The main body 5 has a cylindrical shape whose shape is lower than the diameter, and an axial core insertion hole 11 that is a hole having a circular cross section passes through the axis. Two locking portions 13 are provided on the peripheral surface (side surface) 12 of the main body 5 with an interval of 180 degrees.

係止部１３は、誘導溝１４、凸部１５および保持部１６からなる。
誘導溝１４は、丸座１が扉３に取り付けられたときに表側となる面（「表面１７」という）から裏側となる面（「裏面１８」という）まで本体５の軸心と平行に延びた溝である第１導入部１９、および第１導入部１９の裏側端から、表側から見て右回りに延びた溝である第２導入部２０で構成される。つまり、第１導入部１９と第２導入部２０とは、本体５の裏面１８側で略直角に交わっている。
第１導入部１９の幅（周方向の幅をいう）は、カバー２の内側から突出する突起２１，２１の根元（ねもと）のカバー２周方向における幅Ｗ１と同一またはこれより大きい。 The locking portion 13 includes a guide groove 14, a convex portion 15, and a holding portion 16.
The guide groove 14 extends in parallel with the axis of the main body 5 from a surface (referred to as “front surface 17”) to the back side (referred to as “back surface 18”) when the round seat 1 is attached to the door 3. The first introduction portion 19 is a groove, and the second introduction portion 20 is a groove extending clockwise from the back side end of the first introduction portion 19 when viewed from the front side. That is, the first introduction portion 19 and the second introduction portion 20 intersect at a substantially right angle on the back surface 18 side of the main body 5.
The width of the first introduction portion 19 (referred to as the width in the circumferential direction) is equal to or greater than the width W1 in the circumferential direction of the cover 2 at the bases of the protrusions 21 and 21 protruding from the inside of the cover 2.

凸部１５は、第２導入部２０における第１導入部１９から離れた側の端に接して設けられる。凸部１５は、図２を参照して、その断面形状が弦で２分された円の一方の半円である、本体５軸心方向に延びた本体５径方向外方に突出する帯である。凸部１５の断面形状は、弦が円の中心を通ったときの半円、または弦が円の中心を通らないときの円の中心を含まない方の半円が好ましい。凸部１５は、少なくとも本体５径方向外方に突出する部分を有して、カバー２の突起２１に係止して保持部１６に滞留させることができれば足りる。したがって、凸部１５は、本体５軸心方向に延びた帯状でなく、例えばその形状が半球、台形、角柱等であってもよい。凸部１５は、第２導入部２０の底を基準とするその高さＨが第２導入部２０の深さよりも小さくなっている。   The convex portion 15 is provided in contact with the end of the second introduction portion 20 on the side away from the first introduction portion 19. Referring to FIG. 2, the convex portion 15 is a band projecting outward in the radial direction of the main body 5 extending in the axial direction of the main body 5, which is one semicircle of a circle whose sectional shape is divided into two by a string. is there. The cross-sectional shape of the convex portion 15 is preferably a semicircle when the string passes through the center of the circle, or a semicircle that does not include the center of the circle when the string does not pass through the center of the circle. It is sufficient that the convex portion 15 has at least a portion that protrudes outward in the radial direction of the main body 5 and can be retained in the holding portion 16 by being locked to the protrusion 21 of the cover 2. Therefore, the convex portion 15 may not be a belt-like shape extending in the direction of the axis of the main body 5 but may be a hemisphere, a trapezoid, a prism, or the like. The height H of the convex portion 15 with respect to the bottom of the second introduction portion 20 is smaller than the depth of the second introduction portion 20.

保持部１６は、凸部１５を挟んで第２導入部２０の反対側に配された凹状の、第２導入部２０の本体５周方向延長部分と解することもできる部分である。保持部１６は、周方向において凸部１５に対向する壁面である係止壁２２を備える。係止壁２２は、本体５軸心方向に広がる平面として形成されている。
第２導入部２０、凸部１５および保持部１６にわたって表面１７の側に形成された壁面である側壁２３は、第１導入部１９と第２導入部２０との交差部分から保持部１６に向かうにしたがい裏面１８との距離を狭めて本体５周方向に延びている。側壁２３と裏面１８との距離は、カバー２における開放側端からの突起２１の位置および大きさとの関係で決定される。側壁２３と裏面１８との距離と突起２１の位置等の関係は後に説明する。 The holding portion 16 is a concave portion disposed on the opposite side of the second introduction portion 20 with the convex portion 15 interposed therebetween, and can also be understood as a portion extending in the circumferential direction of the main body 5 of the second introduction portion 20. The holding | maintenance part 16 is provided with the latching wall 22 which is a wall surface which opposes the convex part 15 in the circumferential direction. The locking wall 22 is formed as a flat surface extending in the direction of the axis of the main body 5.
A side wall 23 that is a wall surface formed on the surface 17 side across the second introduction part 20, the convex part 15, and the holding part 16 is directed to the holding part 16 from the intersection of the first introduction part 19 and the second introduction part 20. Accordingly, the distance from the back surface 18 is reduced and the body 5 extends in the circumferential direction. The distance between the side wall 23 and the back surface 18 is determined by the relationship between the position and size of the protrusion 21 from the open side end of the cover 2. The relationship between the distance between the side wall 23 and the back surface 18 and the position of the protrusion 21 will be described later.

第１クリップ部６および第２クリップ部７は、本体５の裏面１８から本体５の軸心方向に、互いに間隔を有して本体５の軸心に対して点対称の位置から突出している。丸座１は、通常、扉３を挟んで両側に同一のものが扉３に取り付けられる。そのため、第１クリップ部６は第２クリップ部７を嵌め入れ可能に形成される。すなわち、扉３の両側の丸座１のうち一方の丸座１の第１クリップ部６に他方の丸座の第２クリップ部７が嵌め入れられ、他方の丸座の第１クリップ部６に一方の丸座１の第２クリップ部７が嵌め入れられて、扉３における両側の丸座１が、錠箱との関係で正しい位置に取り付けられる。   The first clip portion 6 and the second clip portion 7 protrude from a point-symmetrical position with respect to the axis of the main body 5 at a distance from the back surface 18 of the main body 5 in the axial direction of the main body 5. The same circular seat 1 is usually attached to the door 3 on both sides of the door 3. Therefore, the 1st clip part 6 is formed so that the 2nd clip part 7 can be inserted. That is, the second clip portion 7 of the other round seat is fitted into the first clip portion 6 of one of the round seats 1 on both sides of the door 3, and the first clip portion 6 of the other round seat is inserted into the first clip portion 6 of the other round seat. The second clip portion 7 of one of the round seats 1 is fitted, and the round seats 1 on both sides of the door 3 are attached to the correct positions in relation to the lock box.

カバー２は、円筒状の円筒部２４および円筒部２４の一方の端を閉じる平らな底面部２５とからなる。
円筒部２４の内面には、１８０度間隔で配され、いずれも内方に突出する２つの突起２１，２１が設けられている。突起２１は、半球状の外観を有する。円筒部２４の内径は、丸座１における本体５の外径よりもわずかに大きく、円筒部２４は、本体５を略隙間なく嵌め入れることができる。
底面部２５は、その中心に円形の開口２６が形成されている。開口２６の大きさは、本体５における角芯挿通孔１１と同一または角芯挿通孔１１よりも若干大きい。 The cover 2 includes a cylindrical cylindrical portion 24 and a flat bottom surface portion 25 that closes one end of the cylindrical portion 24.
On the inner surface of the cylindrical portion 24, there are provided two protrusions 21 and 21 that are arranged at intervals of 180 degrees and both protrude inward. The protrusion 21 has a hemispherical appearance. The inner diameter of the cylindrical portion 24 is slightly larger than the outer diameter of the main body 5 in the circular seat 1, and the cylindrical portion 24 can fit the main body 5 without a substantial gap.
A circular opening 26 is formed at the center of the bottom surface portion 25. The size of the opening 26 is the same as or slightly larger than the angular core insertion hole 11 in the main body 5.

次に、カバー２における突起２１の位置および大きさと係止部１３における側壁２３の裏面１８からの距離との関係について説明する。
突起２１の位置、つまり図７においてカバー２における底面部２５の内面からの突起２１の最小距離Ｗ２は、図４における係止部１３の所定の位置における側壁２３と表面１７との距離Ｄ１に略等しい。
ここで、「突起２１の最小距離Ｗ２」とは、突起２１におけるカバー２の軸心方向底面部２５側の根元（ねもと）を基準とするものである。また、「係止部１３の所定の位置」とは、保持部１６における係止壁２２と周面１２とが交差して形成する端縁から、第１導入部１９方向に突起２１の幅Ｗ１の２分の１離れた位置である（以下「係止位置」という）。なお、係止位置を決定するＷ１／２は、直線としての距離である。 Next, the relationship between the position and size of the protrusion 21 in the cover 2 and the distance from the back surface 18 of the side wall 23 in the locking portion 13 will be described.
7, the minimum distance W2 of the protrusion 21 from the inner surface of the bottom surface portion 25 in the cover 2 in FIG. 7 is substantially equal to the distance D1 between the side wall 23 and the surface 17 at a predetermined position of the locking portion 13 in FIG. equal.
Here, the “minimum distance W2 of the protrusion 21” is based on the root of the protrusion 21 on the side of the bottom surface 25 in the axial direction of the cover 2. The “predetermined position of the locking portion 13” means the width W1 of the protrusion 21 in the direction of the first introduction portion 19 from the edge formed by the locking wall 22 and the peripheral surface 12 of the holding portion 16 intersecting each other. The position is a half apart (hereinafter referred to as “locking position”). Note that W1 / 2 for determining the locking position is a distance as a straight line.

カバー２は、扉３に取り付けられた後の丸座１に次のようにして取り付けられる。
カバー２の２つの突起２１，２１をそれぞれ丸座１の係止部１３における第１導入部１９に合わせ、そのまま突起２１を第１導入部１９に嵌め入れてカバー２を丸座１に被せる。このとき、突起２１は第１導入部１９（誘導溝１４）に案内されて円滑に進入する。続いて、カバー２を右廻りに止まる位置にまで回す。このとき、突起２１はそれぞれ係止部１３の第２導入部２０に（誘導溝１４）に案内されて円滑に回る。突起２１は、凸部１５に当たってその回転が一旦妨げられるが、突起２１は、凸部１５を乗り越えて係止壁２２に当接して係止部１３に保持される（図８参照）。 The cover 2 is attached to the round seat 1 after being attached to the door 3 as follows.
The two protrusions 21, 21 of the cover 2 are respectively aligned with the first introduction part 19 in the locking part 13 of the round seat 1, and the protrusion 21 is fitted into the first introduction part 19 as it is to cover the cover 2 on the round seat 1. At this time, the protrusion 21 is guided by the first introduction part 19 (guide groove 14) and smoothly enters. Subsequently, the cover 2 is turned clockwise until it stops. At this time, each of the protrusions 21 is smoothly guided by the second introduction portion 20 of the locking portion 13 (guide groove 14). The protrusion 21 hits the convex portion 15 and is temporarily prevented from rotating, but the protrusion 21 gets over the convex portion 15 and comes into contact with the locking wall 22 and is held by the locking portion 13 (see FIG. 8).

側壁２３は、第１導入部１９と第２導入部２０との交差部分から保持部１６に向かうにしたがい裏面１８との距離が狭まり、突起２１が誘導溝１４を進むにしたがい、突起２１の本体５軸心方向の自由度が制限される。そして、突起２１が係止壁２２に当接した状態では、カバー２における底面部２５の内面からの突起２１の最小距離Ｗ２と距離Ｄ１とが等しいために、カバー２は、軸心方向の一方で側壁２３によって突起２１が係止され、他方で丸座１の表面１７によって係止されて、本体５軸心方向の移動が阻止される。また、凸部１５は、突起２１が係止壁２２に当接したとき係止壁２２とは反対側で突起２１を係止可能に設計されており（図８参照）、保持部１６に嵌り込んだ突起２１は、本体５周方向の移動も阻止される。これによって、カバー２はがたつくことなく丸座１にぴったり一体化される。   The side wall 23 decreases in distance from the back surface 18 as it goes from the intersecting portion of the first introduction portion 19 and the second introduction portion 20 toward the holding portion 16, and the main body of the projection 21 as the projection 21 advances through the guide groove 14. The degree of freedom in the 5-axis direction is limited. In the state where the protrusion 21 is in contact with the locking wall 22, the minimum distance W2 of the protrusion 21 from the inner surface of the bottom surface portion 25 of the cover 2 is equal to the distance D1, and therefore the cover 2 Thus, the protrusion 21 is locked by the side wall 23, and on the other hand, the protrusion 21 is locked by the surface 17 of the round seat 1, thereby preventing the movement of the main body 5 in the axial direction. Further, the convex portion 15 is designed to be able to lock the projection 21 on the side opposite to the locking wall 22 when the projection 21 abuts on the locking wall 22 (see FIG. 8), and is fitted to the holding portion 16. The protrusion 21 that is inserted is also prevented from moving in the circumferential direction of the main body 5. As a result, the cover 2 is perfectly integrated with the round seat 1 without rattling.

丸座１において、側壁２３は、第１導入部１９と第２導入部２０との交差部分から保持部１６に向かうにしたがい表面１７との距離を広げて保持部１６に至るように形成されている。一方、設計上は、凸部１５までまたは凸部１５の最高部分（頂上）まで側壁２３と表面１７との距離を徐々に大きくし、保持部１６における側壁２３は、表面１７との距離Ｄ１を底面部２５の内面からの突起２１の最小距離Ｗ２と略等しく一定とすることが簡便である。
また、側壁２３における表面１７との距離が徐々に広がる過程で、側壁２３と表面１７との距離がカバー２の底面部２５の内面からの突起２１の最小距離Ｗ２と等しくなる部分を設けておくことにより、係止部１３に凸部１５を設けなくとも、突起２１と側壁２３とを係合させて、丸座１にカバー２をぴったりと固定することができる。 In the circular seat 1, the side wall 23 is formed to extend from the intersection of the first introduction portion 19 and the second introduction portion 20 to the holding portion 16 and to reach the holding portion 16 as the distance from the surface 17 increases. Yes. On the other hand, in design, the distance between the side wall 23 and the surface 17 is gradually increased up to the convex portion 15 or the highest portion (the top) of the convex portion 15, and the side wall 23 in the holding portion 16 has a distance D <b> 1 with the surface 17. It is convenient to make the distance approximately equal to the minimum distance W2 of the protrusion 21 from the inner surface of the bottom surface portion 25 constant.
Further, in the process of gradually increasing the distance between the side wall 23 and the surface 17, a portion where the distance between the side wall 23 and the surface 17 is equal to the minimum distance W 2 of the protrusion 21 from the inner surface of the bottom surface portion 25 of the cover 2 is provided. Accordingly, the protrusion 2 and the side wall 23 can be engaged with each other without providing the convex portion 15 in the locking portion 13, and the cover 2 can be tightly fixed to the round seat 1.

カバー２を丸座１から取り外すときは、カバー２を左廻りに回す。若干力を込めてカバー２を左に回せば、突起２１は凸部１５を乗り越えて保持部１６から誘導溝１４に移動する。さらにカバー２を突起２１が第１導入部１９に至るまで回せば、簡単にカバー２を丸座１から取り外すことができる。
上述の実施形態において、第１導入部１９および第２導入部２０からなる誘導溝１４を他の形態とすることができる。例えば、側面視（図４に相当）においてＬ字状でなく第１導入部１９の表側端から直線的に凸部１５に延びるように形成してもよい。このように形成された誘導溝であっても、周方向に延びる途中にその側壁と表面１７との距離がカバー２の底面部２５の内面からの突起２１の最小距離Ｗ２と等しくなる部分を設けておくことにより、丸座から凸部１５を省くことができる。 When removing the cover 2 from the round seat 1, turn the cover 2 counterclockwise. When the cover 2 is turned counterclockwise with a slight force, the protrusion 21 moves over the convex portion 15 and moves from the holding portion 16 to the guide groove 14. Further, if the cover 2 is rotated until the projection 21 reaches the first introduction portion 19, the cover 2 can be easily detached from the round seat 1.
In the above-described embodiment, the guide groove 14 including the first introduction part 19 and the second introduction part 20 can be in another form. For example, it may be formed so as not to be L-shaped in a side view (corresponding to FIG. 4) but to extend straight from the front end of the first introduction portion 19 to the convex portion 15. Even in the guide groove formed in this way, a portion where the distance between the side wall and the surface 17 is equal to the minimum distance W2 of the protrusion 21 from the inner surface of the bottom surface portion 25 of the cover 2 is provided in the middle of extending in the circumferential direction. Thus, the convex portion 15 can be omitted from the round seat.

図９に示される丸座１Ｂにおけるように、係止部１３Ｂを、第１導入部１９Ｂが裏面１８に至る手前で終わり、略直交して周方向に延びる第２導入部２０Ｂに連続するようにしてもよい。その場合、係止部１３Ｂは、側壁２３に対向する壁面である第２側壁２７Ｂを備える。第２側壁２７Ｂは、裏面と略平行に延び、保持部１６Ｂにおける前出の係止位置において、側壁２３との間が突起の幅Ｗ１に略等しくされている。丸座１Ｂにおいても、係止部１３Ｂの係止位置における側壁２３の表面１７からの距離Ｄ１は、取り付けられるカバー２における底面部２５の内面からの突起２１の最大距離Ｗ２に等しくされる。   As in the circular seat 1B shown in FIG. 9, the locking portion 13B ends before the first introduction portion 19B reaches the back surface 18 and is continuous with the second introduction portion 20B extending in the circumferential direction substantially orthogonally. May be. In that case, the locking portion 13 </ b> B includes a second side wall 27 </ b> B that is a wall surface facing the side wall 23. The second side wall 27B extends substantially in parallel with the back surface, and the space between the second side wall 27B and the side wall 23 is substantially equal to the width W1 of the protrusion at the above-described locking position in the holding portion 16B. Also in the circular seat 1B, the distance D1 from the surface 17 of the side wall 23 at the locking position of the locking portion 13B is made equal to the maximum distance W2 of the protrusion 21 from the inner surface of the bottom surface portion 25 in the cover 2 to be attached.

丸座１Ｂにおいて、第２側壁２７Ｂを、側壁２３との間隔を、第１導入部１９Ｂから係止位置に至るまでは突起の幅Ｗ１以上に維持して凸部１５Ｂに向かうにつれて裏面１８に近づくように斜めに設けてもよい。このとき、側壁２３も第２側壁と同様にに向かうにつれて裏面１８に近づくように斜めに設けられる。
係止部１３，１３Ｂにおける側壁２３、凸部１５，１５Ｂおよび係止壁２２は、カバー２の凸部１５，１５Ｂが保持部１６，１６Ｂに嵌り込んだときに本体５，５Ｂ軸心方向および周方向の移動を妨げるように形成されれば足り、上記のように、第２導入部２０，２０Ｂの始点から保持部１６に向かうにしたがい裏面１８との距離を狭めて本体５，５Ｂ周方向に延びるものでなくともよく、さらに係止壁２２を平面でなく曲面として形成してもよい。 In the circular seat 1B, the distance between the second side wall 27B and the side wall 23 is maintained to be equal to or greater than the width W1 of the protrusion until reaching the locking position from the first introduction portion 19B, and approaches the back surface 18 toward the convex portion 15B. You may provide diagonally. At this time, the side wall 23 is also provided obliquely so as to approach the back surface 18 as it goes in the same manner as the second side wall.
The side wall 23, the convex portions 15, 15 B and the locking wall 22 in the locking portions 13, 13 B are arranged in the axial direction of the main body 5, 5 B when the convex portions 15, 15 B of the cover 2 are fitted into the holding portions 16, 16 B. It suffices if it is formed so as to prevent the movement in the circumferential direction, and as described above, the distance from the back surface 18 is reduced from the starting point of the second introduction part 20, 20 B toward the holding part 16, and the body 5, 5 B circumferential direction The locking wall 22 may be formed as a curved surface instead of a flat surface.

係止部１３，１３Ｂは、カバー２の突起２１の数と同数設けられる。係止部１３，１３Ｂの数は２に限られず、３以上であってもよい。また、係止部１３，１３Ｂの数は突起２１の数以上であつてもよい。例えば、カバー２の突起２１が１８０度間隔で２つ設けられ、係止部１３，１３Ｂが９０度間隔で４つ設けられていてもよい。係止部１３，１３Ｂは、カバー２が丸座１，１Ｂに被せられたときに、係止部１３，１３Ｂがその一部または全部に周方向において突起２１が重なるように配置されていればよい。
丸座１，１Ｂの係止部１３，１３Ｂにおける係止位置（係止壁２２から周方向にＷ／２の距離の位置）および係止位置における側壁２３の表面１７からの距離Ｄ１を、図１０に示された既存のカバー８１における突起８２，８２の大きさおよび位置（突起２１の最小距離Ｗ２）に合わせて、既存のカバー８１を丸座１に取り付けてもよい。 The number of the locking portions 13 and 13B is the same as the number of the protrusions 21 of the cover 2. The number of the locking portions 13 and 13B is not limited to 2, and may be 3 or more. Further, the number of the locking portions 13 and 13B may be equal to or more than the number of the protrusions 21. For example, two protrusions 21 of the cover 2 may be provided at intervals of 180 degrees, and four locking portions 13 and 13B may be provided at intervals of 90 degrees. The locking portions 13 and 13B may be arranged such that when the cover 2 is put on the round seats 1 and 1B, the locking portions 13 and 13B are arranged so that the protrusions 21 overlap with part or all of the locking portions 13 and 13B in the circumferential direction. Good.
The locking position (position at a distance W / 2 in the circumferential direction from the locking wall 22) in the locking portions 13 and 13B of the circular seats 1 and 1B and the distance D1 from the surface 17 of the side wall 23 at the locking position are shown in FIG. The existing cover 81 may be attached to the round seat 1 in accordance with the size and position (the minimum distance W2 of the protrusion 21) of the protrusions 82, 82 in the existing cover 81 shown in FIG.

カバーは、丸座２と凹凸関係にある円筒部２４および底面部２５を有するものでなく、外観が四角柱または楕円柱等の、丸座１，１Ｂと異なる外観形状を有するものとすることができる。その場合、カバーは、その内面に設けられた内方に突出する少なくとも２つの突起の距離が取り付け対象の丸座１の外径よりも若干小さく、底面部の内面からの突起の最小距離Ｗ２が取り付け対象の丸座１の係止部１３における所定の側壁２３の位置と表面１７との距離Ｄ１に略等しく形成される。
