Description

本発明は、例えば、手持ち機器や手持ち工具やバッグやリュックやカメラケースやクーラーボックスやキャディバッグなどの携行物を肩に掛けて携行する際に使用する肩掛けベルトに係り、特に、刈払機やブロワーや噴霧器等の手持ち機器並びにハンマドリル等の手持ち工具などのように比較的重量がある携行物を上下方向や前後方向や左右方向に動かして使用する際に肩に吊り下げたり、動力源等から振動が伝わる携行物を肩に吊り下げたりする場合に適した肩掛けベルトに関するものである。   The present invention relates to a shoulder belt used for carrying a hand-held device, a hand-held tool, a bag, a backpack, a camera case, a cooler box, a caddy bag or the like on a shoulder. Hanging on a shoulder when using a relatively heavy carrying object such as a hand-held device such as a sprayer or a hand-held tool such as a hammer drill, etc. The present invention relates to a shoulder belt suitable for suspending a carried item carrying a message on a shoulder.

図２（ａ）（ｂ）に示す従来の肩掛けベルト１の肩パッド２においては、発泡ウレタン素材を扁平な直方体に成形したものを塩化ビニール等の樹脂シートで包み込むとともに、帯体３が挿通された帯通し２ａが設けられている。なお、下記特許文献１にもこれと同種の肩掛けベルトが開示されている。
特開２００４−４９６２１号公報 In the shoulder pad 2 of the conventional shoulder belt 1 shown in FIGS. 2 (a) and 2 (b), a foamed urethane material formed into a flat rectangular parallelepiped is wrapped with a resin sheet such as vinyl chloride, and the band 3 is inserted. A banding 2a is provided. Patent Document 1 below also discloses a shoulder belt of the same type.
JP 2004-49621 A

上記従来の肩パッド２は帯体３に対しその長手方向Ｘへ移動し得るため、作業時に肩パッド２が移動してずれたり肩から外れると、肩や首の付根が痛くなったり、携行物の振動が直接肩に伝わり、疲労が増大した。また、ずれた肩パッド２を気にするあまり、ストレスが溜まり、さらに疲労が増大した。例えば、携行物が刈払機である場合、作業時には刈払機を多方向に振って使用するとともに、動力源からの振動が肩に伝わり、肩には多方向の負荷が掛かる。   Since the conventional shoulder pad 2 can move in the longitudinal direction X with respect to the band 3, if the shoulder pad 2 moves and is displaced or disengaged from the shoulder during work, the shoulder or neck of the shoulder may hurt or be carried The vibration directly transmitted to the shoulder and fatigue increased. In addition, the stress accumulated due to worrying about the misaligned shoulder pad 2, and the fatigue further increased. For example, when the carried item is a brush cutter, the brush cutter is used in multiple directions during work, vibration from the power source is transmitted to the shoulder, and a multi-directional load is applied to the shoulder.

この発明は、各種携行物を肩に吊り下げて使用する際に肩に加わる負荷の変動を抑えて使用者の疲労を低減することができる肩掛けベルトを提供することを目的としている。   An object of the present invention is to provide a shoulder belt that can reduce a user's fatigue by suppressing a variation in a load applied to the shoulder when using the various items to be carried on the shoulder.

後記実施形態の図面（図１（ａ）（ｂ）（ｃ）（ｄ）に示す本発明と関連しない第１実施形態、図１（ｅ）に示す第２実施形態、図１（ｆ）または図１（ｇ）に示す第３実施形態）の符号を援用して本発明を説明する。 Drawing of postscript embodiment (1st Embodiment which is not related to this invention shown to FIG.1 (a) (b) (c) (d), 2nd Embodiment shown in FIG.1 (e), FIG.1 (f) or The present invention will be described with reference to the reference numeral of the third embodiment shown in FIG.

請求項１の発明にかかる肩掛けベルトは、携行物を吊り下げるためのものであって、第２〜３実施形態に対応し、下記のように構成されている。
この肩掛けベルト１においては、帯体３を肩パッド２の両側で互いに離間する両連結部４により取着している。この肩パッド２はこの両連結部４を結ぶ帯体３の長手方向Ｘで伸縮し得る伸縮材により設けられている。この両連結部４のうち一方の連結部４側の片側領域部９と、この両連結部４のうち他方の連結部４側の片側領域部１０と、それらの片側領域部９，１０間の中間領域部１１とにこの肩パッド２を帯体３の長手方向Ｘで区分した場合、この肩パッド２の中間領域部１１の伸長率よりもこの肩パッド２の片側領域部９，１０の伸長率を大きくしている。請求項１の発明では、肩パッド２が長手方向Ｘへ伸縮するため、携帯物により生じる長手方向Ｘへの荷重や衝撃を分散して吸収することができるとともに、肩に当接している中間領域部１１よりも片側領域部９，１０が伸縮するため、その中間領域部１１の形状変化を長手方向Ｘで抑制して肩や首の付根に対する肩パッド２の食い込みを防止することができる。なお、帯体３については、携行物を肩に掛けて携行する際の安定上、非伸縮性（帯体３を非伸縮材によりまたは極僅かにしか伸縮しない材質により設けた場合の状態）であることが好ましい。 The shoulder belt according to the invention of claim 1 is for suspending a carried item, and corresponds to the second to third embodiments and is configured as follows.
In the shoulder belt 1, the band 3 is attached by both connecting portions 4 that are separated from each other on both sides of the shoulder pad 2. The shoulder pad 2 is provided by an elastic material that can expand and contract in the longitudinal direction X of the band 3 that connects both the connecting portions 4. Of these two connecting portions 4, one side region 9 on the one connecting portion 4 side, one side region 10 on the other connecting portion 4 side out of both connecting portions 4, and between the one side region portions 9 and 10 When the shoulder pad 2 is divided into the middle region 11 in the longitudinal direction X of the band 3, the elongation of the one side regions 9, 10 of the shoulder pad 2 is larger than the elongation rate of the middle region 11 of the shoulder pad 2. The rate is increasing. In the invention of claim 1, since the shoulder pad 2 expands and contracts in the longitudinal direction X, it is possible to disperse and absorb the load and impact in the longitudinal direction X caused by the portable object, and to contact the shoulder Since the one side region portions 9 and 10 extend and contract with respect to the portion 11, the shape change of the intermediate region portion 11 can be suppressed in the longitudinal direction X, and the shoulder pad 2 can be prevented from biting into the shoulder or neck root. The belt 3 is non-stretchable (when the belt 3 is provided with a non-stretchable material or a material that stretches only slightly) for stability when carrying a carrying item on the shoulder. Preferably there is.

請求項１の発明を前提とする請求項２の発明（第２〜３実施形態に対応）において、前記肩パッド２は前記両連結部４を結ぶ帯体３の長手方向Ｘばかりでなくその長手方向Ｘに対し直交する全方向Ｙ，Ｚで伸縮し得る伸縮材により設けられている。請求項２の発明では、肩パッド２が多方向Ｘ，Ｙ，Ｚへ伸縮するため、携帯物により生じる多方向Ｘ，Ｙ，Ｚへの荷重や衝撃を分散して吸収することができる。 In the invention of claim 2 that assumes the first aspect (corresponding to the 2-3 embodiment), the shoulder pad 2 is the longitudinal as well as the longitudinal direction X of the strip 3 connecting the two joining portions 4 It is provided by an elastic material that can expand and contract in all directions Y and Z orthogonal to the direction X. In the invention of claim 2, to stretch the shoulder pad 2 multidirectional X, Y, the Z, multidirectional X caused by the portable object, Y, Ru can be absorbed by dispersing a load or impact to Z.

請求項２の発明を前提とする請求項３の発明（第２〜３実施形態に対応）において、前記肩パッド２は主体７とその主体７の外周縁に取着された縁取部８を有し、その主体７と縁取部８とを共に前記伸縮材により設けている。請求項３の発明では、肩パッド２を縁取部８により補強するばかりでなく、肩パッド２の全体の伸縮性を維持することができる。 In the invention of claim 3 (corresponding to the second to third embodiments) based on the invention of claim 2, the shoulder pad 2 has a main body 7 and an edge portion 8 attached to the outer peripheral edge of the main body 7. The main body 7 and the edge portion 8 are both provided by the stretchable material. In the invention of claim 3, not only the shoulder pad 2 is reinforced by the edge portion 8, but also the overall stretchability of the shoulder pad 2 can be maintained.

本発明は、肩掛けベルト１において各種携行物を肩に吊り下げて使用する際に肩に加わる負荷の変動を抑えて使用者の疲労を低減することができる。   The present invention can reduce the fatigue of the user by suppressing fluctuations in the load applied to the shoulder when various carried items are suspended from the shoulder in the shoulder belt 1.

まず、本発明と関連しない第１実施形態にかかる肩掛けベルトについて図１（ａ）（ｂ）（ｃ）（ｄ）を参照して説明する。
各種携行物を吊り下げる肩掛けベルト１においては、肩パッド２の両側で両帯体３の端部３ａが互いに離間する両連結部４により取着され、この両帯体３が長さ調節金具５により互いに連結されているとともに、各種携行物を保持するための吊下フック６がこの帯体３に１個以上取り付けられている。この連結部４で肩パッド２と帯体３の端部３ａとは、接着や溶着によりまたは縫製によりまたはそれらの組み合わせることにより、互いに取着されている。この両連結部４を結ぶ帯体３の長手方向Ｘに対し直交する幅方向Ｙで、肩パッド２の幅寸法Ｗ２が両帯体３の端部３ａの幅寸法Ｗ３よりも大きくなっている。この肩パッド２は、長手方向Ｘ及び幅方向Ｙに対し直交する厚さ方向Ｚで厚み寸法Ｔ２が同一の薄い板状をなす主体７と、その主体７の外周縁全体に縫製等により取着された縁取部８とを備えている。この肩パッド２の主体７と縁取部８とは、共に、長手方向Ｘばかりでなく、その長手方向Ｘに対し直交する全方向（幅方向Ｙや厚さ方向Ｚ等）で伸縮し得る伸縮材により設けられ、クッション性を有している。この伸縮材としては、例えば、天然繊維や合成繊維等を用いて伸縮可能に織込んだ布地（ゴム繊布やジャージ生地等）、または、発泡ウレタンや合成ゴムや天然ゴムや合成樹脂等を用いて成形したもの、または、それらを組み合わせたものを採用する。一方、前記帯体３は、非伸縮材により、または、極僅かにしか伸縮しない材質により設けられている。この非伸縮材としては、例えば、天然繊維や合成繊維等を用いて非伸縮性を有するように織込んだ布地（綿繊布やＰＰ系繊維テープ等）、または、金属や合成樹脂等を用いて成形したもの、または、それらを組み合わせたものを採用する。 First, a shoulder belt according to a first embodiment not related to the present invention will be described with reference to FIGS. 1 (a), (b), (c), and (d).
In the shoulder belt 1 for suspending various items to be carried, the end portions 3a of the two band bodies 3 are attached to both sides of the shoulder pad 2 by the connecting portions 4 that are separated from each other. Are connected to each other, and at least one suspension hook 6 for holding various items to be carried is attached to the belt 3. In this connecting portion 4, the shoulder pad 2 and the end portion 3a of the band 3 are attached to each other by bonding, welding, sewing, or a combination thereof. The width dimension W2 of the shoulder pad 2 is larger than the width dimension W3 of the end portions 3a of the two band bodies 3 in the width direction Y orthogonal to the longitudinal direction X of the band body 3 connecting the two connecting portions 4.

A molded one or a combination thereof is adopted.

次に、本発明の第２実施形態にかかる肩掛けベルトについて第１実施形態との相違点を中心に図１（ｅ）を参照して説明する。
肩パッド２は、両連結部４のうち一方の連結部４を含む片側領域部９と、両連結部４のうち他方の連結部４を含む片側領域部１０と、それらの片側領域部９，１０間の中間領域部１１とに長手方向Ｘで区分されている。この中間領域部１１と片側領域部９，１０とは、それぞれ、主体７と、それらの主体７の外周縁全体及び各主体７間の境界縁に取着された縁取部８とを備えている。この肩パッド２の主体７と縁取部８とは、共に、長手方向Ｘばかりでなく、その長手方向Ｘに対し直交する全方向（幅方向Ｙや厚さ方向Ｚ等）で伸縮し得る伸縮材により設けられ、クッション性を有している。この肩パッド２において、中間領域部１１の伸長率よりも片側領域部９，１０の伸長率が大きくなっている。片側領域部９の伸長率と片側領域部１０の伸長率とは、互いに同一になっているが、一方の伸長率が他方の伸長率よりも大きくしてもよい。その際、中間領域部１１の主体７の伸長率よりも片側領域部９，１０の主体７の伸長率を大きくするとともに、中間領域部１１の縁取部８の伸長率よりも片側領域部９，１０の縁取部８の伸長率を大きくするが、中間領域部１１の縁取部８の伸長率と片側領域部９，１０の縁取部８の伸長率とを互いに同一にしてもよく、肩パッド２の全体として中間領域部１１と片側領域部９，１０との間で伸長率に差が生じればよい。この中間領域部１１（主体７及び縁取部８）とこの片側領域部９，１０（主体７及び縁取部８）との間で、それらの材質を互いに変更したり、それらの編目や織目を変えて密度（組成内の空隙容積）を互いに変更したりして、それらの伸縮率に差を持たせることができる。 Next, a shoulder belt according to a second embodiment of the present invention will be described with reference to FIG. 1 (e), focusing on differences from the first embodiment.
The shoulder pad 2 includes a one-side region 9 including one of the connecting portions 4, a one-side region 10 including the other of the connecting portions 4, and the one-side region 9, It is divided in the longitudinal direction X into 10 intermediate region portions 11. Each of the intermediate region portion 11 and the one-side region portions 9 and 10 includes a main body 7 and an edge portion 8 attached to the entire outer peripheral edge of the main body 7 and a boundary edge between the main bodies 7. . Both the main body 7 and the edge portion 8 of the shoulder pad 2 can be expanded and contracted not only in the longitudinal direction X but also in all directions (width direction Y, thickness direction Z, etc.) orthogonal to the longitudinal direction X. It has a cushioning property. In the shoulder pad 2, the extension rate of the one side region portions 9 and 10 is larger than the extension rate of the intermediate region portion 11. The elongation rate of the one-side region portion 9 and the elongation rate of the one-side region portion 10 are the same, but one elongation rate may be larger than the other. In that case, while making the expansion | extension rate of the main body 7 of the one side area | region parts 9 and 10 larger than the expansion | extension rate of the main body 7 of the intermediate | middle area part 11, the one side area | region part 9 and 10 Although the elongation rate of the edge portion 8 of 10 is increased, the elongation rate of the edge portion 8 of the intermediate region portion 11 and the elongation rate of the edge portion 8 of the one side region portions 9 and 10 may be the same. As a whole, it suffices if there is a difference in the elongation ratio between the intermediate region 11 and the one-side regions 9 and 10. The intermediate region 11 (main body 7 and the edge portion 8) and the one-side area portions 9 and 10 (main body 7 and the edge portion 8) can be changed in their materials, or their stitches and textures can be changed. It is possible to change the density (void volume in the composition) to each other to make a difference in the expansion / contraction ratio.

次に、本発明の第３実施形態にかかる肩掛けベルトについて第１実施形態との相違点を中心に図１（ｆ）または図１（ｇ）を参照して説明する。
肩パッド２は、両連結部４のうち一方の連結部４を含む片側領域部９と、両連結部４のうち他方の連結部４を含む片側領域部１０と、それらの片側領域部９，１０間の中間領域部１１とに長手方向Ｘで区分されている。この肩パッド２の主体７と縁取部８とは、共に、長手方向Ｘばかりでなく、その長手方向Ｘに対し直交する全方向（幅方向Ｙや厚さ方向Ｚ等）で伸縮し得る伸縮材により設けられ、クッション性を有している。図１（ｆ）に示すように、この肩パッド２において、中間領域部１１の幅寸法Ｗ１１よりも片側領域部９，１０の幅寸法Ｗ９，Ｗ１０を小さくしてそれらの外形状を互いに変更しているので、中間領域部１１の伸長率よりも片側領域部９，１０の伸長率が大きくなっている。片側領域部９の幅寸法Ｗ９と片側領域部１０の幅寸法Ｗ１０とは、互いに同一になっているが、一方の幅寸法が他方の幅寸法よりも大きくしてもよい。また、図１（ｇ）に示すように、この肩パッド２において、中間領域部１１の厚み寸法Ｔ１１よりも片側領域部９，１０の厚み寸法Ｔ９，Ｔ１０を小さくしてそれらの外形状を互いに変更しているので、中間領域部１１の伸長率よりも片側領域部９，１０の伸長率が大きくなっている。片側領域部９の厚み寸法Ｔ９と片側領域部１０の厚み寸法Ｔ１０とは、互いに同一になっているが、一方の厚み寸法が他方の厚み寸法よりも大きくしてもよい。その際、中間領域部１１の主体７の伸長率よりも片側領域部９，１０の主体７の伸長率を大きくするとともに、中間領域部１１の縁取部８の伸長率よりも片側領域部９，１０の縁取部８の伸長率を大きくするが、中間領域部１１の縁取部８の伸長率と片側領域部９，１０の縁取部８の伸長率とを互いに同一にしてもよく、肩パッド２の全体として中間領域部１１と片側領域部９，１０との間で伸長率に差が生じればよい。図示しないが、図１（ｆ）に示す構成と図１（ｇ）に示す構成とを互いに組み合わせてもよい。 Next, a shoulder belt according to a third embodiment of the present invention will be described with reference to FIG. 1 (f) or FIG. 1 (g), focusing on differences from the first embodiment.
The shoulder pad 2 includes a one-side region 9 including one of the connecting portions 4, a one-side region 10 including the other of the connecting portions 4, and the one-side region 9, It is divided in the longitudinal direction X into 10 intermediate region portions 11. Both the main body 7 and the edge portion 8 of the shoulder pad 2 can be expanded and contracted not only in the longitudinal direction X but also in all directions (width direction Y, thickness direction Z, etc.) orthogonal to the longitudinal direction X. It has a cushioning property. As shown in FIG. 1 (f), in this shoulder pad 2, the width dimensions W9 and W10 of the one side area portions 9 and 10 are made smaller than the width dimension W11 of the intermediate area portion 11 and their outer shapes are changed to each other. Therefore, the expansion rate of the one-side region portions 9 and 10 is larger than the expansion rate of the intermediate region portion 11. The width dimension W9 of the one-side area portion 9 and the width dimension W10 of the one-side area portion 10 are the same, but one width dimension may be larger than the other width dimension. Further, as shown in FIG. 1 (g), in this shoulder pad 2, the thickness dimensions T9, T10 of the one-side area portions 9, 10 are made smaller than the thickness dimension T11 of the intermediate area portion 11, so that their outer shapes are mutually connected. Since the change is made, the extension rate of the one-side region portions 9 and 10 is larger than the extension rate of the intermediate region portion 11. Although the thickness dimension T9 of the one-side area portion 9 and the thickness dimension T10 of the one-side area portion 10 are the same, one thickness dimension may be larger than the other thickness dimension. In that case, while making the expansion | extension rate of the main body 7 of the one side area | region parts 9 and 10 larger than the expansion | extension rate of the main body 7 of the intermediate | middle area part 11, the one side area | region part 9 and 10 Although the elongation rate of the edge portion 8 of 10 is increased, the elongation rate of the edge portion 8 of the intermediate region portion 11 and the elongation rate of the edge portion 8 of the one side region portions 9 and 10 may be the same. As a whole, it suffices if there is a difference in the elongation ratio between the intermediate region 11 and the one-side regions 9 and 10. Although not shown, the configuration shown in FIG. 1 (f) and the configuration shown in FIG. 1 (g) may be combined with each other.

第２〜３実施形態のように、肩パッド２を一方の片側領域部９と他方の片側領域部１０とそれらの片側領域部９，１０間の中間領域部１１とで長手方向Ｘへ三区分する以外に、肩パッド２を長手方向Ｘへ三区分以上してもよく、その場合には中央側領域部から長手方向Ｘへ離れる両側領域部ほど伸長率を大きくする。   As in the second to third embodiments, the shoulder pad 2 is divided into three in the longitudinal direction X by one one-side region portion 9, the other one-side region portion 10, and an intermediate region portion 11 between these one-side region portions 9 and 10. In addition to this, the shoulder pad 2 may be divided into three or more sections in the longitudinal direction X. In that case, the elongation rate is increased in the both side regions away from the central region in the longitudinal direction X.

本実施形態は下記の効果を有する。
＊ 第１〜３実施形態の肩掛けベルト１では、肩パッド２が帯体３の長手方向Ｘばかりでなくその長手方向Ｘに対し直交する全方向（幅方向Ｙや厚さ方向Ｚ等）で伸縮し得る伸縮材により設けられているので、肩パッド２が肩の凹凸に倣うよう変形して肩に対する肩パッド２の密着度が増すとともに、携帯物により生じる多方向への荷重や衝撃を分散して吸収することができる。例えば、刈払機や噴霧器等の動力源からの振動をも吸収することができる。 This embodiment has the following effects.
* In the shoulder belt 1 of the first to third embodiments, the shoulder pad 2 expands and contracts not only in the longitudinal direction X of the belt 3 but also in all directions (width direction Y, thickness direction Z, etc.) perpendicular to the longitudinal direction X. Since the shoulder pad 2 is deformed so as to follow the unevenness of the shoulder, the degree of adhesion of the shoulder pad 2 to the shoulder increases, and multidirectional loads and impacts caused by portable objects are dispersed. Can be absorbed. For example, vibrations from a power source such as a brush cutter or a sprayer can be absorbed.

＊ 第２〜３実施形態の肩掛けベルト１の肩パッド２では、過度の荷重が加わっても、肩に当接している中間領域部１１よりも帯体３側の片側領域部９，１０が伸び縮みするため、肩に当接している中間領域部１１の形状変化を長手方向Ｘや幅方向Ｙ等で抑制し、携帯物により生じる多方向への荷重や衝撃を分散して吸収することができるとともに、肩や首の付根に対する肩パッド２の食い込みまでも防止することができる。   * In the shoulder pad 2 of the shoulder belt 1 according to the second to third embodiments, even if an excessive load is applied, the one side region portions 9 and 10 on the belt body 3 side extend from the intermediate region portion 11 in contact with the shoulder. In order to shrink, the shape change of the intermediate region 11 in contact with the shoulder can be suppressed in the longitudinal direction X, the width direction Y, etc., and the load and impact in multiple directions caused by the portable object can be dispersed and absorbed. At the same time, it is possible to prevent the shoulder pad 2 from biting into the root of the shoulder or neck.

＊ 第１〜３実施形態の肩掛けベルト１の肩パッド２では、伸縮性を有する主体７を縁取部８により補強することができるばかりでなく、この縁取部８にも伸縮性を持たせているため、肩パッド２の全体の伸縮性を維持することができる。   * In the shoulder pad 2 of the shoulder belt 1 of the first to third embodiments, not only the stretchable main body 7 can be reinforced by the edge portion 8, but also the edge portion 8 is made elastic. Therefore, the overall elasticity of the shoulder pad 2 can be maintained.

＊ 第１〜３実施形態の肩掛けベルト１では、比較的幅寸法の広い肩パッド２を有し、この肩パッド２の長手方向Ｘの両側に帯体３を取着しているので、肩に対する肩パッド２の当接面積が大きくなって肩の一部に過度の負荷が加わることを防止するとともに、携行物を多方向へ動かしても肩パッド２がずれたり肩から外れたりすることを防止する。   * The shoulder belt 1 according to the first to third embodiments has a shoulder pad 2 having a relatively wide width, and the belt body 3 is attached to both sides of the shoulder pad 2 in the longitudinal direction X. The contact area of the shoulder pad 2 is increased to prevent an excessive load from being applied to a part of the shoulder, and the shoulder pad 2 is prevented from being displaced or detached from the shoulder even if the carrying object is moved in multiple directions. To do.
