Description

本発明は、ベルトアジャスタに関し、より詳細には、ベルトをスライドさせて長さ寸法を調節する、例えば、ランドセルの肩ベルト長さを微調節可能なベルトアジャスタに関する。 The present invention relates to a belt adjuster, and more particularly to a belt adjuster that adjusts a length dimension by sliding a belt, for example, a shoulder belt length of a school bag can be finely adjusted.

従来、ベルト長さを調節可能な調節具としては、バックルとこれに取り付けられたピンとからなり、ピンをベルト穴に差し込んでベルト長さを調節する美錠や、スキー靴などの平ベルトの長さを調節可能なベルト締着用のバックルが開示されている（例えば、特許文献１参照。）。図１５に示すように、特許文献１に開示されているベルト締着用のバックル５０は、軸５１に支承されて揺動自在に配設されたラックベルト係止体５２のストッパ部５３をラックベルト５４の鋸刃状ラック部５５に係止させ、また回動操作部５６を押圧することで板ばね５７の付勢力に抗して該係止を解除させて、長さの微調整を可能にしている。 Conventionally, as an adjuster that can adjust the belt length, it consists of a buckle and a pin attached to the buckle, and the length of a flat belt such as a beautiful tablet or a ski boot that adjusts the belt length by inserting the pin into the belt hole A buckle for tightening a belt that can be adjusted is disclosed (for example, see Patent Document 1). As shown in FIG. 15, a buckle 50 for fastening a belt disclosed in Patent Document 1 is provided with a stopper 53 of a rack belt locking body 52 that is supported by a shaft 51 and is swingably disposed. 54 is engaged with the saw-toothed rack portion 55 and the rotation operation portion 56 is pressed to release the engagement against the urging force of the leaf spring 57, thereby enabling fine adjustment of the length. ing.

ところで、ベルトやランドセルの肩ベルトなどに適用される美錠は、予めベルトにあけられたベルト穴のピッチの範囲内でベルト長さを調節するので長さの微調整ができないという課題がある。また、特許文献１に記載のベルト締着用のバックル５０では長さの微調整は可能であるが、回動操作部５６の位置が軸５１を跨いで設けられているので、軸５１上方の回動操作部５６を押圧した場合にはストッパ部５３の係止が解除し難く、操作性にさらなる改善が求められる。 By the way, the beauty lock applied to a belt, a shoulder belt of a school bag, etc. has a problem that the length cannot be finely adjusted because the belt length is adjusted within the range of the pitch of the belt holes previously formed in the belt. In addition, the length of the buckle 50 for fastening the belt described in Patent Document 1 can be finely adjusted. However, since the position of the rotation operation unit 56 is provided across the shaft 51, the rotation above the shaft 51 is possible. When the moving operation part 56 is pressed, the stopper part 53 is difficult to release, and further improvement in operability is required.

本発明は、前述した課題に鑑みてなされたものであり、その目的は、ベルト長さの調整時に操作部を目視によらず確実に認識することができ、操作性が改善された、ベルト長さを微調整可能なベルトアジャスタを提供することにある。 The present invention has been made in view of the above-described problems, and its object is to reliably recognize the operation portion without visual observation when adjusting the belt length, and to improve the operability of the belt length.

Therefore, regarding the belt adjuster, the insertion direction of the belt to the belt adjuster is the front-rear direction, the belt width direction orthogonal to the belt insertion direction is the left-right direction (width direction), and the direction orthogonal to the front-rear direction and the left-right direction is the vertical direction (thickness). Direction). In the figure, F, B, L, R, U, and D indicate front, rear, left, right, upper, and lower, respectively, based on the direction of the belt adjuster.

図１及び図２に示すように、ベルトアジャスタ１０は、例えば、不図示のランドセルの一方の肩ベルトに取り付けられており、他方の肩ベルト１を挿通して、ベルトアジャスタ１０に対する肩ベルト１の相対位置によってベルト長さが調整される。肩ベルト１は、皮革、合成ゴムなどにより細幅の薄板状に成形されており、肩ベルト１の表面２側には、傾斜面３ａと垂直面３ｂとで構成される係止突起３ｃ間に係止溝３が肩ベルト１の幅方向に沿って多数形成され、これらの係止溝３によりラック４が形成されている。 As shown in FIGS. 1 and 2, the belt adjuster 10 is attached to, for example, one shoulder belt of a school bag (not shown), and the shoulder belt 1 is inserted into the other shoulder belt 1 to the belt adjuster 10. The belt length is adjusted by the relative position. The shoulder belt 1 is formed into a thin thin plate shape using leather, synthetic rubber, or the like, and on the surface 2 side of the shoulder belt 1, there is a gap between the locking projections 3 c constituted by the inclined surface 3 a and the vertical surface 3 b. A number of locking grooves 3 are formed along the width direction of the shoulder belt 1, and a rack 4 is formed by these locking grooves 3.

ベルトアジャスタ１０は、アジャスタ本体１１と、係止部材１２と、カバー１３とが組立てられて構成され、アジャスタ本体１１のベルト挿通孔１８に肩ベルト１が挿通される。 The belt adjuster 10 is configured by assembling an adjuster body 11, a locking member 12, and a cover 13, and the shoulder belt 1 is inserted into the belt insertion hole 18 of the adjuster body 11.

図３から図６も参照して、アジャスタ本体１１は、肩ベルト１の表面側に設けられた略矩形板状の基部１４と、基部１４の左右両端部からそれぞれ立設された左右一対の側壁１５Ｒ、１５Ｌと、基部１４と反対側（裏面側）で一対の側壁１５Ｒ、１５Ｌの前側端部同士、後側端部同士をそれぞれ連結する一対の連結部１６Ｆ、１６Ｂと、を備える。アジャスタ本体１１は、合成樹脂により形成することで軽量化されている。 3 to 6, the adjuster main body 11 includes a substantially rectangular plate-like base portion 14 provided on the front surface side of the shoulder belt 1 and a pair of left and right side walls respectively erected from both left and right end portions of the base portion 14. 15R, 15L, and a pair of connecting portions 16F, 16B for connecting the front end portions and the rear end portions of the pair of side walls 15R, 15L on the opposite side (rear surface side) from the base portion 14, respectively. The adjuster body 11 is reduced in weight by being formed of a synthetic resin.

基部１４に対向してアジャスタ本体１１の裏面側には、一対の側壁１５Ｒ、１５Ｌ及び一対の連結部１６Ｆ、１６Ｂによって、カバー１３が取り付けられる略矩形開口部１７が画成される。従って、アジャスタ本体１１の基部１４、一対の側壁１５Ｒ、１５Ｌ、及び一対の連結部１６Ｆ、１６Ｂと、略矩形開口部１７に取り付けられたカバー１３とによって、肩ベルト１が挿通されるベルト挿通孔１８が、アジャスタ本体１１の前後方向に沿って形成される。
また、基部１４より前方に延設された一対の側壁１５Ｒ、１５Ｌの先端部同士は、ベルト取付バー１９で連結されており、該ベルト取付バー１９には一方の肩ベルトが取り付けられる。A substantially rectangular opening 17 to which the cover 13 is attached is defined on the back side of the adjuster body 11 so as to face the base portion 14 by a pair of side walls 15R and 15L and a pair of connecting portions 16F and 16B. Accordingly, the belt insertion hole through which the shoulder belt 1 is inserted by the base portion 14 of the adjuster body 11, the pair of side walls 15R and 15L, the pair of connection portions 16F and 16B, and the cover 13 attached to the substantially rectangular opening portion 17. 18 is formed along the front-rear direction of the adjuster body 11.
Further, the tip portions of the pair of side walls 15R, 15L extending forward from the base portion 14 are connected to each other by a belt attachment bar 19, and one shoulder belt is attached to the belt attachment bar 19.

図４（ｂ）から図６に示すように、一対の側壁１５Ｒ、１５Ｌの内壁面には、アジャスタ本体１１の基部１４寄りの部分が内側に突出して厚肉とされた支持壁２０が形成されている。支持壁２０には、後述する係止部材１２の揺動軸部３２を支持する曲面状の支持面２１が上方に開放されて、略Ｕ字溝状に形成されている（図１２（ｂ）も参照）。また、支持面２１より下部の支持壁２０には、支持面２１に向かうに従って、即ち上方に向かうに従って次第に肉厚が厚くなるように傾斜する傾斜面２３が形成されている。上下方向において支持面２１が形成される基部１４の部分には、上方から支持面２１が臨むように開口孔２２が形成されている。開口孔２２は、支持面２１を形成するための金型（図示せず）が挿入可能となるように形成されている。 As shown in FIGS. 4B to 6, a support wall 20 is formed on the inner wall surface of the pair of side walls 15 </ b> R and 15 </ b> L so that a portion near the base 14 of the adjuster body 11 protrudes inward and is thickened. ing. The support wall 20 has a curved support surface 21 that supports a swing shaft portion 32 of the locking member 12 described later, and is formed in a substantially U-shaped groove shape (FIG. 12B). See also). In addition, the support wall 20 below the support surface 21 is formed with an inclined surface 23 that is inclined so as to gradually increase in thickness toward the support surface 21, that is, upward. An opening 22 is formed in the portion of the base portion 14 where the support surface 21 is formed in the vertical direction so that the support surface 21 faces from above. The opening hole 22 is formed so that a mold (not shown) for forming the support surface 21 can be inserted.

また、アジャスタ本体１１の基部１４には、支持面２１より後方に位置して、アジャスタ本体１１の下方に向かって凹む曲面部２４が形成され、該曲面部２４の略中央には、基部１４を貫通する開口部２５が形成されている。開口部２５には、後述する係止部材１２の操作部３４が突出して配置される。これにより、ベルトアジャスタ１０を目視しない状態でも指で曲面部２４を探ることで、開口部２５から突出する操作部３４を容易に認識することができる。 Further, the base portion 14 of the adjuster main body 11 is formed with a curved surface portion 24 that is located rearward of the support surface 21 and is recessed toward the lower side of the adjuster main body 11. A penetrating opening 25 is formed. In the opening 25, an operation portion 34 of the locking member 12 to be described later is disposed so as to protrude. Accordingly, even when the belt adjuster 10 is not visually observed, the operation portion 34 protruding from the opening 25 can be easily recognized by searching the curved surface portion 24 with a finger.

図２及び図３に示すように、アジャスタ本体１１には、支持面２１より前方に位置して、アジャスタ本体１１の基部１４にアジャスタ本体１１内部のベルト挿通孔１８に向けて突出する一対の付勢部２６が一体に設けられている。 As shown in FIGS. 2 and 3, the adjuster main body 11 has a pair of attachments that are located in front of the support surface 21 and protrude from the base portion 14 of the adjuster main body 11 toward the belt insertion hole 18 inside the adjuster main body 11. The force part 26 is provided integrally.

付勢部２６は、後述する係止部材１２の板状部分に当接するように屈曲して形成され、上下方向に弾性変形可能であり、係止部材１２を回動付勢する。付勢部２６は、一対の側壁１５Ｒ、１５Ｌから幅方向内側に延びる片持ち梁状に形成することで、アジャスタ本体１１の前後方向寸法を大きくすることなく比較的長く形成することができる。これにより、バネ定数が小さくなり、係止部材１２を操作する際の操作力変化を小さくして操作感の向上が図られる。付勢部２６に対応する基部１４にも、上方から付勢部２６全体を臨むように長孔２７が形成されており、長孔２７は、付勢部２６を形成するための金型（図示せず）が挿入可能となるように形成されている。 The urging portion 26 is formed to be bent so as to abut on a plate-like portion of the locking member 12 described later, is elastically deformable in the vertical direction, and urges the locking member 12 to rotate. The urging portion 26 is formed in a cantilever shape extending inward in the width direction from the pair of side walls 15R and 15L, so that it can be formed relatively long without increasing the longitudinal dimension of the adjuster body 11. As a result, the spring constant is reduced, and the change in operating force when operating the locking member 12 is reduced to improve the operational feeling. A long hole 27 is formed in the base 14 corresponding to the urging portion 26 so as to face the entire urging portion 26 from above, and the long hole 27 is a mold for forming the urging portion 26 (see FIG. (Not shown) can be inserted.

図７から図９に示すように、係止部材１２は、長手方向（前後方向）に延びる板状部分３１と、アジャスタ本体１１の支持面２１により揺動自在に支持される略円柱状の一対の揺動軸部３２とを備え、合成樹脂により形成されている。一対の揺動軸部３２に対して板状部分３１の一端側（前方側）には、ラック４の係止溝３に係止可能な係止部３３が設けられ、他端側（後方側）には、操作部３４が設けられている。 As shown in FIGS. 7 to 9, the locking member 12 includes a pair of substantially cylindrical members that are swingably supported by a plate-like portion 31 extending in the longitudinal direction (front-rear direction) and a support surface 21 of the adjuster body 11. , And is made of synthetic resin. A locking portion 33 that can be locked in the locking groove 3 of the rack 4 is provided on one end side (front side) of the plate-like portion 31 with respect to the pair of swing shaft portions 32, and the other end side (rear side). ) Is provided with an operation unit 34.

板状部分３１は、左右方向に伸びる一対の腕部３８を有し、一対の揺動軸部３２は、腕部３８の上面から上方に突出して形成されることで、板状部分３１に対して上方にオフセットしている。具体的に、図９に示すように、側面視で、係止部３３の先端Ｐと、操作部３４と反対側の面３６における他端側の端部３６ａとを結ぶ線を延長線Ｌとし、該延長線Ｌに垂直で、且つ、揺動軸部３２の軸心Ｏを通過する線を垂直線Ｖとする。このとき、一対の揺動軸部３２の軸心Ｏは、垂直線Ｖに沿った位置での板状部分３１の肉厚中間点Ｏ´よりも、板状部分３１の上面３９側にオフセットしている。 The plate-like portion 31 has a pair of arm portions 38 extending in the left-right direction, and the pair of swinging shaft portions 32 are formed to protrude upward from the upper surface of the arm portion 38, so that the plate-like portion 31 is opposed to the plate-like portion 31. Offset upwards. Specifically, as shown in FIG. 9, a line connecting the distal end P of the locking portion 33 and the end portion 36 a on the other end side of the surface 36 on the opposite side to the operation portion 34 in the side view is defined as an extension line L. A line perpendicular to the extension line L and passing through the axis O of the oscillating shaft portion 32 is defined as a vertical line V. At this time, the axis O of the pair of oscillating shaft portions 32 is offset to the upper surface 39 side of the plate-like portion 31 with respect to the thickness intermediate point O ′ of the plate-like portion 31 at the position along the vertical line V. ing.

また、係止部材１２は、上述した延長線Ｌが、ベルト１の挿通方向において、揺動軸部３２よりも一端側でベルト１と交差するように、アジャスタ本体１１に取り付けられている（図１１参照。）。このため、係止部材１２が、板状部分３１の上面３９側にオフセットされた揺動軸部３２の軸心Ｏを中心として揺動すると、操作部３４の端部３４ａは、軸心Ｏを中心とする円弧ｔに沿って移動する。一方、揺動軸部３２の軸心を板状部分３１の上面３９側にオフセットせずに、例えば、板状部材３１の肉厚中間点Ｏ’を中心として揺動する場合、操作部３４の端部３４ａはＯ’を中心とする円弧ｔ’に沿って移動する。従って、一対の揺動軸部３２の軸心Ｏを板状部分３１の上面３９側にオフセットした場合には、操作部３４は、その端部３４ａが、ベルト１の挿通方向において揺動軸部３２側へ移動しながら押し込まれる一方、係止部材１２を肉厚中間点Ｏ´を中心として揺動させた場合には、操作部３４は、その端部３４ａが、ベルト１の挿通方向において、揺動軸部３２から離れる方向に移動しながら押し込まれることになる。このように、一対の揺動軸部３２の軸心Ｏを板状部分３１の上面３９側にオフセットすることにより、端部３４ａを揺動軸部３２側へ移動させながら操作部３４を操作することができ、操作感が向上する。 Further, the locking member 12 is attached to the adjuster body 11 so that the above-described extension line L intersects the belt 1 at one end side of the swing shaft portion 32 in the insertion direction of the belt 1 (see FIG. 11). For this reason, when the locking member 12 swings about the axis O of the swinging shaft portion 32 that is offset to the upper surface 39 side of the plate-like portion 31, the end 34 a of the operation portion 34 moves the shaft center O around. It moves along the center arc t. On the other hand, when the axis of the swing shaft 32 is not offset to the upper surface 39 side of the plate-like portion 31, for example, when swinging around the wall thickness intermediate point O ′ of the plate-like member 31, The end 34a moves along an arc t ′ centered on O ′. Therefore, when the axis O of the pair of swing shaft portions 32 is offset to the upper surface 39 side of the plate-shaped portion 31, the operation portion 34 has an end portion 34 a in the swing direction of the belt 1. When the locking member 12 is swung around the wall thickness intermediate point O ′ while being moved toward the side 32, the operation portion 34 has an end portion 34 a in the insertion direction of the belt 1. It is pushed in while moving away from the swinging shaft portion 32. As described above, the operation center 34 is operated while the end 34 a is moved to the swing shaft portion 32 side by offsetting the axis O of the pair of swing shaft portions 32 to the upper surface 39 side of the plate-like portion 31. Can improve the operational feeling.

図８に示すように、一対の揺動軸部３２の端面は、上方に向かうに従って次第に両端面間の間隔が狭くなるように傾斜する傾斜面３５となっている。係止部材１２をアジャスタ本体１１に組み付ける際、一対の揺動軸部３２の傾斜面３５を、アジャスタ本体１１の支持壁２０に設けられた傾斜面２３に摺接させながら係止部材１２を上方に押圧することで組付けが容易となる。 As shown in FIG. 8, the end surfaces of the pair of oscillating shaft portions 32 are inclined surfaces 35 that incline so that the distance between the both end surfaces becomes gradually narrower toward the upper side. When the locking member 12 is assembled to the adjuster body 11, the locking member 12 is moved upward while sliding the inclined surfaces 35 of the pair of swing shaft portions 32 against the inclined surface 23 provided on the support wall 20 of the adjuster body 11. Assembling is facilitated by pressing to.

また、一対の揺動軸部３２の軸心Ｏは、板状部分３１の上面３９側にオフセットしているので、図６に示すように、オフセット量分だけ一対の揺動軸部３２を支持する支持壁２０はアジャスタ本体１１の基部１４寄りに配置することができる。これにより、支持壁２０と肩ベルト１とが干渉し難くなるので肩ベルト１を係止部材１２に近づけ配置することでベルトアジャスタ１０を薄肉化することができる。 Further, since the axis O of the pair of swing shaft portions 32 is offset to the upper surface 39 side of the plate-like portion 31, as shown in FIG. 6, the pair of swing shaft portions 32 is supported by the offset amount. The supporting wall 20 can be disposed near the base 14 of the adjuster body 11. Thereby, since the support wall 20 and the shoulder belt 1 do not easily interfere with each other, the belt adjuster 10 can be thinned by arranging the shoulder belt 1 close to the locking member 12.

図９に示すように、係止部材１２は、他端側の端部３６ａから係止部３３に向かって略平坦に形成された第１の下面３６と、該第１の下面３６と係止部３３側で連続し、第１の下面３６に対して上方（板状部分３１の上面３９側）に屈曲した第２の下面３７とを有する。係止部３３は、この第２の下面３７から下方（肩ベルト１側）に突出して形成され、係止部３３の先端Ｐは、第１の下面３６の延長線Ｌ´上に位置している。なお、係止部３３の先端Ｐは、第１の下面３６の延長線Ｌ´よりも第２の下面３７側に位置してもよい。また、図９中、上述した係止部３３の先端Ｐと操作部３４の裏面とを結ぶ延長線Ｌと、下面３６の延長線Ｌ´は、本実施形態では一致しているが、係止部３３の先端Ｐの位置によってはこれに限らない。 As shown in FIG. 9, the locking member 12 includes a first lower surface 36 that is formed to be substantially flat from the end 36 a on the other end side toward the locking portion 33, and the first lower surface 36 is locked to the first lower surface 36. The second lower surface 37 is continuous on the part 33 side and is bent upward (upper surface 39 side of the plate-like portion 31) with respect to the first lower surface 36. The locking portion 33 is formed so as to protrude downward (from the shoulder belt 1 side) from the second lower surface 37, and the tip P of the locking portion 33 is located on the extension line L ′ of the first lower surface 36. Yes. The distal end P of the locking portion 33 may be positioned closer to the second lower surface 37 than the extension line L ′ of the first lower surface 36. In FIG. 9, the extension line L connecting the tip P of the locking portion 33 and the back surface of the operation portion 34 and the extension line L ′ of the lower surface 36 are the same in this embodiment. The position is not limited to this depending on the position of the tip P of the portion 33.

これにより、操作部３４を押圧して係止部３３と肩ベルト１との係止を解除すると、図１１に一点鎖線で示すように、係止部材１２の第１の下面３６が肩ベルト１の表面２と略平行となり、また、係止部材１２には、第１の下面３６から肩ベルト１側へ突出するものがないので、肩ベルト１を係止部材１２に近接した位置に配置することができる。従って、ベルトアジャスタ１０の薄型化が可能となる。 As a result, when the operating portion 34 is pressed to release the locking between the locking portion 33 and the shoulder belt 1, the first lower surface 36 of the locking member 12 is moved to the shoulder belt 1 as shown by a one-dot chain line in FIG. 11. Further, since there is no protrusion that protrudes from the first lower surface 36 toward the shoulder belt 1 side, the shoulder belt 1 is disposed at a position close to the engagement member 12. be able to. Therefore, the belt adjuster 10 can be thinned.

また、図９に示すように、係止部材１２は、揺動軸部３２の軸心Ｏと係止部３３の先端Ｐとの間の最短距離である第１の距離Ｌ１が、揺動軸部３２の軸心Ｏと操作部３４の端部３４ａとの間の最短距離である第２の距離Ｌ２よりも短く設定されている。これにより、係止部３３と肩ベルト１との係止を解除するための操作部３４のストロークを大きくとることができ、衣服などと操作部３４との接触による誤作動が防止される。 Further, as shown in FIG. 9, the locking member 12 has a first distance L1 that is the shortest distance between the axis O of the swinging shaft portion 32 and the tip P of the locking portion 33. It is set to be shorter than the second distance L2, which is the shortest distance between the axis O of the portion 32 and the end 34a of the operation portion 34. Thereby, the stroke of the operation part 34 for releasing the engagement between the engagement part 33 and the shoulder belt 1 can be increased, and malfunction due to contact between clothes and the operation part 34 is prevented.

係止部材１２のアジャスタ本体１１への組付けは、アジャスタ本体１１の裏面に形成された矩形開口部１７から係止部材１２をアジャスタ本体１１内に挿入し、図１２（ａ）に示すように、一対の揺動軸部３２の傾斜面３５を、アジャスタ本体１１の支持壁２０に設けられた傾斜面２３に摺接させながら上方に押圧することで、一対の揺動軸部３２、腕部３８及び支持壁２０が幅方向に弾性変形して支持面２１に組み付けられる。これにより、図１２（ｂ）に示すように、一対の揺動軸部３２は、アジャスタ本体１１の支持面２１により揺動自在に支持される。
また、図５及び図８を参照して、一対の揺動軸部３２の最長幅Ｗ１は、支持壁２０の最短幅Ｗ２よりも長く形成されることから、係止部材１２が組み付け後にアジャスタ本体１１から脱落することがない。As shown in FIG. 12A, the locking member 12 is assembled to the adjuster body 11 by inserting the locking member 12 into the adjuster body 11 from the rectangular opening 17 formed on the back surface of the adjuster body 11. By pressing the inclined surfaces 35 of the pair of swing shaft portions 32 upward while making sliding contact with the inclined surfaces 23 provided on the support wall 20 of the adjuster body 11, the pair of swing shaft portions 32 and arm portions are pressed. 38 and the support wall 20 are elastically deformed in the width direction and assembled to the support surface 21. Thereby, as shown in FIG. 12B, the pair of swing shaft portions 32 is swingably supported by the support surface 21 of the adjuster body 11.
5 and 8, since the longest width W1 of the pair of swing shaft portions 32 is formed longer than the shortest width W2 of the support wall 20, the adjuster main body is assembled after the locking member 12 is assembled. 11 will not drop off.

また同時に、アジャスタ本体１１の両側壁１５Ｒ、１５Ｌから幅方向内側に延びる片持ち梁状の付勢部２６が、揺動軸部３２より係止部３３側（前側）において板状部分３１の上面に当接し、付勢部２６の付勢力により係止部材１２の係止部３３を肩ベルト１に係止する方向に回動させる。このとき、操作部３４側の板状部分３１の上面は、開口部２５を画成する基部１４の揺動軸部寄りの縁部２５ａに当接して、係止部材１２の揺動範囲（係止部３３の係止溝３方向への揺動）が制限される。 At the same time, the cantilever-like urging portion 26 extending inward in the width direction from the both side walls 15R, 15L of the adjuster body 11 has an upper surface of the plate-like portion 31 on the locking portion 33 side (front side) from the swing shaft portion 32. The locking portion 33 of the locking member 12 is rotated in the direction of locking to the shoulder belt 1 by the biasing force of the biasing portion 26. At this time, the upper surface of the plate-like portion 31 on the operation portion 34 side abuts on the edge portion 25a near the swing shaft portion of the base portion 14 that defines the opening portion 25, and the swing range (engagement of the locking member 12). The swing of the stopper 33 in the direction of the locking groove 3) is limited.

図１０はカバーの斜視図であり、カバー１３は、外方に僅かに湾曲形成された板部４１を備え、該板部４１の裏面に、アジャスタ本体１１の矩形開口部１７に嵌合可能な矩形枠体４２と、先端に左右方向両側に突出する係合部４３が設けられた一対の係合脚部４４とが、形成されている。カバー１３は、矩形枠体４２をアジャスタ本体１１の矩形開口部１７に嵌合させると共に、係合脚部４４の係合部４３をアジャスタ本体１１の係合溝２８（図４（ｂ）、図６参照）に係合させてアジャスタ本体１１に取り付けられている。 FIG. 10 is a perspective view of the cover. The cover 13 includes a plate portion 41 that is slightly curved outward, and can be fitted to the rectangular opening 17 of the adjuster body 11 on the back surface of the plate portion 41. A rectangular frame body 42 and a pair of engagement leg portions 44 provided with engagement portions 43 protruding at both ends in the left-right direction are formed. The cover 13 fits the rectangular frame body 42 into the rectangular opening 17 of the adjuster main body 11, and engages the engaging portion 43 of the engaging leg portion 44 with the engaging groove 28 (FIG. 4B, FIG. 6). And is attached to the adjuster body 11.

なお、カバー１３は、ベルトアジャスタ１０の必須部材ではないが、アジャスタ本体１１の矩形開口部１７を覆って内部を見えないようにすることでベルトアジャスタ１０の商品価値を高める。また、板部４１の表面側にロゴや装飾模様などを施して装飾性を向上させることもできる。なお、カバー１３を設けない場合には、アジャスタ本体１１は、一対の連結部１６Ｆ、１６Ｂの代わりに、一対の側壁１５Ｒ、１５Ｌの基部１４と反対側（裏面側）の端部を板状部分によって連結してもよい。 The cover 13 is not an essential member of the belt adjuster 10, but increases the commercial value of the belt adjuster 10 by covering the rectangular opening 17 of the adjuster body 11 so that the inside is not visible. Further, the decorativeness can be improved by applying a logo, a decorative pattern, or the like on the surface side of the plate portion 41. In the case where the cover 13 is not provided, the adjuster body 11 has a plate-like portion on the opposite side (back side) to the base portion 14 of the pair of side walls 15R and 15L instead of the pair of connecting portions 16F and 16B. You may connect by.

従って、肩ベルト１の長さ調整は、係止部材１２の操作部３４を付勢部２６の付勢力に抗して押圧し、係止部３３を肩ベルト１から離間する方向に移動させた状態で行なわれる。そして、適切な長さとなった状態で、操作部３４の押圧を解除することで、係止部３３が付勢部２６の付勢力により係止溝３に係止することで、肩ベルト１とベルトアジャスタ１０との相対位置が決定される。このように、肩ベルト１の長さは、係止溝３のピッチに応じて調整することができ、長さの微調整を容易に行うことができる。 Therefore, the length of the shoulder belt 1 is adjusted by pressing the operation portion 34 of the locking member 12 against the biasing force of the biasing portion 26 and moving the locking portion 33 in a direction away from the shoulder belt 1. Done in state. And in the state which became appropriate length, by releasing the press of the operation part 34, the latching | locking part 33 latches by the latching groove | channel 3 with the urging | biasing force of the urging | biasing part 26, and shoulder belt 1 and A relative position with respect to the belt adjuster 10 is determined. As described above, the length of the shoulder belt 1 can be adjusted according to the pitch of the locking grooves 3, and the length can be easily finely adjusted.

なお、付勢部２６の付勢力や、係止部３３と係止溝３との係合度合いによっては、係止部３３がラック４の傾斜面３ａで押し上げられながら、肩ベルト１をベルトアジャスタ１０のベルト挿通孔１８に挿通することで、長さ調整を行なうことができるようにしてもよい。 Depending on the urging force of the urging portion 26 and the degree of engagement between the locking portion 33 and the locking groove 3, the shoulder belt 1 may be moved while the locking portion 33 is pushed up by the inclined surface 3 a of the rack 4. The length may be adjusted by being inserted through the ten belt insertion holes 18.

以上説明したように、本実施形態のベルトアジャスタ１０によれば、アジャスタ本体１１と、係止部材１２と、を備え、アジャスタ本体１１の基部１４には、係止部材１２の操作部３４が突出する開口部２５が形成されているので、ベルト長さの調整時に操作部３４の位置を目視によらず確実に認識にすることができ、操作性を向上することができる。 As described above, according to the belt adjuster 10 of the present embodiment, the adjuster body 11 and the locking member 12 are provided, and the operation portion 34 of the locking member 12 protrudes from the base portion 14 of the adjuster body 11. Since the opening portion 25 is formed, the position of the operation portion 34 can be reliably recognized without visual observation when adjusting the belt length, and the operability can be improved.

また、係止部材１２は、基部１４のうち、開口部２５を画成する揺動軸部寄りの縁部２５ａによって係止溝３方向への揺動が規制されているので、アジャスタ本体１１に肩ベルト１が挿通されていない状態でも係止部材１２がガタツキなく保持される。 Further, since the locking member 12 is restricted from swinging in the direction of the locking groove 3 by the edge 25a near the swinging shaft portion that defines the opening 25 in the base portion 14, the adjuster body 11 Even when the shoulder belt 1 is not inserted, the locking member 12 is held without rattling.

また、開口部２５の周囲には、開口部２５に向けて凹む曲面部２４が形成されているので、開口部２５が基部１４の表面から凹んだ位置となるので、操作部３４も基部１４の表面から大きく突出することがなく、操作部３４が意図せずに押圧されて肩ベルト１との係止が不用意に解除されるのを防止することができる。また、開口部２５からの操作部３４の突出量を少なくしても、操作部３４のストロークを稼ぐことができ、コンパクト化することができる。 Further, since the curved surface portion 24 that is recessed toward the opening portion 25 is formed around the opening portion 25, the opening portion 25 is in a position that is recessed from the surface of the base portion 14, so that the operation portion 34 is also provided on the base portion 14. It does not protrude greatly from the surface, and it can be prevented that the operation portion 34 is pressed unintentionally and the engagement with the shoulder belt 1 is inadvertently released. Moreover, even if the protrusion amount of the operation part 34 from the opening part 25 is reduced, the stroke of the operation part 34 can be earned and it can be made compact.

また、一対の側壁１５Ｒ、１５Ｌには、揺動軸部３２を支持する支持面２１を形成する支持壁２０が内側に向かって突出形成されているので、別部品を設けることなくアジャスタ本体１１で係止部材１２を支持することができ、部品点数が削減される。また、揺動軸部３２を短くすることができ、係止部材１２の剛性が高まる。 In addition, since the support wall 20 that forms the support surface 21 that supports the swing shaft portion 32 is formed on the pair of side walls 15R and 15L so as to protrude inward, the adjuster body 11 can be provided without providing another part. The locking member 12 can be supported, and the number of parts is reduced. Further, the swinging shaft portion 32 can be shortened, and the rigidity of the locking member 12 is increased.

また、一対の揺動軸部３２の各端面３５は傾斜すると共に、支持壁２０は該揺動軸部３２の傾斜する端面３５と摺接可能な傾斜面２３を有するので、揺動軸部３２の端面３５を支持壁２０の傾斜面２３に摺接させながら押圧することで、係止部材１２の組付けが容易となり、揺動軸部３２をアジャスタ本体１１の支持面２１に支持させることができる。 In addition, each end surface 35 of the pair of swing shaft portions 32 is inclined, and the support wall 20 has an inclined surface 23 that can be slidably contacted with the inclined end surface 35 of the swing shaft portion 32. The end surface 35 is pressed while being brought into sliding contact with the inclined surface 23 of the support wall 20, so that the locking member 12 can be easily assembled and the swing shaft portion 32 can be supported on the support surface 21 of the adjuster body 11. it can.

また、係止部材１２は係止部３３と操作部３４との間に延びる板状部分３１を備え、側面視で、係止部３３の先端Ｐと、操作部３４と反対側の面３６における他端側の端部３６ａとを結ぶ線を延長線Ｌとし、該延長線Ｌに垂直で、且つ、揺動軸部３２の軸心Ｏを通過する線を垂直線Ｖとしたとき、一対の揺動軸部３２の軸心Ｏは、垂直線Ｖに沿った位置での板状部分３１の肉厚中間点Ｏ´よりも、板状部分３１の上面３９側にオフセットしている。したがって、オフセット量分だけ支持壁２０はアジャスタ本体１１の基部１４寄りに配置することができる。これにより、支持壁２０と肩ベルト１とが干渉し難くなるので肩ベルト１を係止部材１２に近づけ配置することでベルトアジャスタ１０を薄肉化することができる。 Further, the locking member 12 includes a plate-like portion 31 extending between the locking portion 33 and the operation portion 34, and in a side view, on the front end P of the locking portion 33 and the surface 36 opposite to the operation portion 34. When a line connecting the end 36a on the other end side is an extension line L, a line perpendicular to the extension line L and passing through the axis O of the oscillating shaft portion 32 is a vertical line V, a pair of The axis O of the oscillating shaft portion 32 is offset to the upper surface 39 side of the plate-like portion 31 with respect to the thickness intermediate point O ′ of the plate-like portion 31 at the position along the vertical line V. Therefore, the support wall 20 can be disposed closer to the base portion 14 of the adjuster body 11 by the offset amount. Thereby, since the support wall 20 and the shoulder belt 1 do not easily interfere with each other, the belt adjuster 10 can be thinned by arranging the shoulder belt 1 close to the locking member 12.

また、係止部材１２は係止部３３と操作部３４との間に延びる板状部分３１を備え、側面視で、係止部３３の先端Ｐと、操作部３４と反対側の面３６における他端側の端部３６ａとを結ぶ線を延長線Ｌとし、該延長線Ｌに垂直で、且つ、揺動軸部３２の軸心Ｏを通過する線を垂直線Ｖとしたとき、一対の揺動軸部３２の軸心Ｏは、垂直線Ｖに沿った位置での板状部分３１の肉厚中間点Ｏ´よりも、板状部分３１の上面３９側にオフセットしている。さらに、係止部材１２は、延長線Ｌがベルト１の挿通方向において揺動軸部３２よりも一端側でベルト１と交差するように、アジャスタ本体１１に取り付けられる。これにより、操作部３４を揺動軸部３２側へ移動させながら操作部３４を押し込むことができ、揺動軸部３２の軸心Ｏがオフセットされていない場合に比べて、操作感が向上する。 Further, the locking member 12 includes a plate-like portion 31 extending between the locking portion 33 and the operation portion 34, and in a side view, on the front end P of the locking portion 33 and the surface 36 opposite to the operation portion 34. When a line connecting the end 36a on the other end side is an extension line L, a line perpendicular to the extension line L and passing through the axis O of the oscillating shaft portion 32 is a vertical line V, a pair of The axis O of the oscillating shaft portion 32 is offset to the upper surface 39 side of the plate-like portion 31 with respect to the thickness intermediate point O ′ of the plate-like portion 31 at the position along the vertical line V. Further, the locking member 12 is attached to the adjuster body 11 so that the extension line L intersects the belt 1 at one end side of the swing shaft portion 32 in the insertion direction of the belt 1. As a result, the operation unit 34 can be pushed in while moving the operation unit 34 toward the swinging shaft portion 32, and the operational feeling is improved compared to the case where the axis O of the swinging shaft portion 32 is not offset. .

また、付勢部２６は、アジャスタ本体１１の基部１４にアジャスタ本体１１内部のベルト挿通孔１８に向けて突出するように一体に形成されるので、部品点数を削減することができ、製作費用を抑制することができる。 Further, since the urging portion 26 is integrally formed on the base portion 14 of the adjuster body 11 so as to protrude toward the belt insertion hole 18 inside the adjuster body 11, the number of parts can be reduced and the manufacturing cost can be reduced. Can be suppressed.

また、付勢部２６は、アジャスタ本体１１の一対の側壁１５Ｒ、１５Ｌから幅方向内側に延びる片持ち梁状に形成されているので、付勢部２６を長手方向（前後方向）に延設する場合に比べて、アジャスタ本体１１が大きくならず、付勢部２６をコンパクトに形成することができる。 Further, since the urging portion 26 is formed in a cantilever shape extending inward in the width direction from the pair of side walls 15R, 15L of the adjuster body 11, the urging portion 26 extends in the longitudinal direction (front-rear direction). Compared to the case, the adjuster body 11 is not enlarged, and the urging portion 26 can be formed compactly.

また、係止部材１２、操作部３４側から係止部３３に向かって略平坦な第１の下面３６と、第１の下面３６と係止部側で連続し、該第１の下面３６に対して上方に屈曲した第２の下面３７とを有する。係止部３３は、第２の下面３７から肩ベルト１側に突出しており、係止部３３の先端Ｐは、第１の下面３６の延長線Ｌ´上に位置するので、係止部３３と肩ベルト１との係止を解除した時、係止部３３を含む係止部材１２の第１の下面３６がほぼフラットになり、肩ベルト１を係止部材１２に近付けて配置することができ、ベルトアジャスタ１０の薄肉化が可能となる。 In addition, the first lower surface 36 that is substantially flat toward the locking portion 33 from the locking member 12 and the operation portion 34 side is continuous with the first lower surface 36 on the locking portion side. The second lower surface 37 is bent upward. The locking portion 33 protrudes from the second lower surface 37 toward the shoulder belt 1, and the distal end P of the locking portion 33 is located on the extension line L ′ of the first lower surface 36. When the locking between the shoulder belt 1 and the shoulder belt 1 is released, the first lower surface 36 of the locking member 12 including the locking portion 33 becomes substantially flat, and the shoulder belt 1 can be disposed close to the locking member 12. Thus, the belt adjuster 10 can be thinned.

また、揺動軸部３２の軸心Ｏと係止部３３の先端Ｐとの間の最短距離である第１の距離Ｌ１は、揺動軸部３２の軸心Ｏと操作部３４の端部３４ａとの間の最短距離である第２の距離Ｌ２よりも短いので、係止部３３と肩ベルト１との係止を解除するための操作部３４のストロークが大きくなり、誤作動による係止解除が防止される。また、操作部３４の操作力が低減して操作性が向上する。 Further, the first distance L1 that is the shortest distance between the axis O of the oscillating shaft portion 32 and the tip P of the locking portion 33 is the axis O of the oscillating shaft portion 32 and the end portion of the operation portion 34. Since it is shorter than the second distance L2, which is the shortest distance between the operating portion 34a, the stroke of the operating portion 34 for releasing the locking between the locking portion 33 and the shoulder belt 1 is increased, and locking due to malfunction is caused. Release is prevented. In addition, the operation force of the operation unit 34 is reduced and the operability is improved.
