Description

【０００１】
【発明の属する技術分野】
本発明は、作業者の肩に装着され、重量物を肩に載せて運ぶときに使用する肩当ての技術に関する。
より詳細には、工事現場等において、直射日光により表面温度が上昇した鋼条や鋼管等を肩に載せて運ぶ時に、作業者の肌に直接温度が上昇した部分を接触させず、かつ重量による肩への負担を軽減する為の肩当ての技術に関する。
【０００２】
【従来の技術】
従来から、工事現場等で鋼条や鋼管等の重量物を担持する作業は、作業者の肩にこれらの重量物が食い込むため、作業者の肩への負担が大きいものであった。そのため、作業者は肩と重量物の間にタオルを折り畳んだものを挟むなどしていた。また、特に収穫した砂糖黍などを搬出する際に使用されるものとして、実開昭６２−１３６４０７に記載の如き肩当てが公知となっている。
【０００３】
【発明が解決しようとする課題】
工事現場等で使用される鋼条や鋼管等は、夏場など直射日光が当たる場所に放置されていた場合、その表面はかなりの高温となるため、作業着の上から担持したとしてもその熱が肩まで伝わり、このままで担持することは事実上困難である。そのため、これらを肩に担持して搬送する際には、重量による肩への負担と、高温の重量物からの熱の遮断とを両立する必要がある。
本発明は、以上の如き状況に鑑み、重量物を肩に担持するときの重量による肩への負担を軽減するとともに、高温の重量物からの熱の遮断を可能とする肩当てを提供するものである。
【０００４】
【課題を解決するための手段】
本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段を説明する。
【０００５】
即ち、請求項１においては、担持部と、パッド部と、一対の側部と、該側部間を連結する係止部とを備えるものである。
【０００６】
請求項２においては、前記一対の側部を左右略対称形状に構成したものである。
【０００７】
請求項３においては、作業者への装着時において、担持部が当接する作業者の肩と反対側の作業者胴体側面に係止部が巻回されるものである。
【０００８】
請求項４においては、前記係止部を長さ調整可能に構成したものである。
【０００９】
請求項５においては、前記パッド部の上面と下面とにそれぞれ長手方向が異なる溝を設けたものである。
【００１０】
【発明の実施の形態】
次に、発明の実施の形態を説明する。
図１は本発明の肩当ての第一実施例を示す斜視図、図２は本発明の肩当ての第一実施例を示す平面図、図３はパッド部の第一実施例の斜視図、図４はパッド部の第一実施例の上面図、図５はパッド部の第一実施例の右側面図、図６はパッド部の第一実施例の下面図、図７はパッド部の第一実施例の後面図、図８はパッド部の第二実施例の斜視図、図９は本発明の肩当ての第二実施例を示す斜視図、図１０は本発明の肩当ての第二実施例を示す平面図、図１１はパッド部の第三実施例の斜視図である。
【００１１】
まず、本発明の第一実施例である肩当て１の全体構成について、図１および図２を用いて説明する。
肩当て１は主に、担持部２、側部３・４、係止部５およびパッド部６などからなる。
図２に示す如く、担持部２は略長方形で内部が袋状に形成されるとともに、布や樹脂、ゴムなど、作業者の肩になじみやすい可撓性の材料で構成される。また担持部２の四辺の内、一辺は開口部２ａとなっており、該開口部２ａより後述するパッド部６が内装される。
【００１２】
側部３・４は、担持部２の開口部２ａと隣り合う二辺に縫着、接着等の方法で取り付けられるか、または担持部２と一体的に成形される略三角形の部材であり、担持部２と略同様に布や樹脂、ゴムなど、作業者の肩になじみやすい可撓性の材料で構成される。図２に示す如く、側部３・４は略同じ形状であり、開口部２ａを上向きとしたときに担持部２と側部３・４とを合わせたものはその形状が略左右対称である。
このように構成することにより、作業者は肩当て１を右肩および左肩のどちらでも装着可能である。
【００１３】
係止部５は、その両端が側部３・４のそれぞれの先端部３ａ・４ａに取り付けられる。該係止部５は担持部２と略同様に布や樹脂、ゴムなどで構成された紐または帯状の部材であり、長さ調整が可能に長さ調整部材７が設けられる。また、係止部５を伸縮可能なゴム帯やゴム紐などで構成した場合、長さ調整部材７を省略しても良い。
そして、係止部５は、例えば図１に示す如く肩当て１が作業者の左肩に装着される場合には、作業者の胴体右側に巻回、当接させることにより肩当て１を固定する。すなわち、係止部５は、装着される方の肩から反対側の脇の下に通されて肩当て１を作業者の肩に係止するのである。
このように構成することにより、肩当て１は作業者が重量物を担持しているときにもずれることが無く、また肩当て１を装着している方の脇の下は大きく開口した形となっており、肩当て１を装着している側の肩や腕の動きを阻害することが無く作業性に優れる。さらに、側部３・４の面積を、肩当て１を作業者の体からずれることなく係止可能な必要最小限の大きさとすることにより、夏場の使用時においても作業者が暑さを感じることなく快適性に優れる。
【００１４】
続いて図３から図７を用いてパッド部の第一実施例であるパッド部６の詳細を説明する。なお、以下のパッド部６の説明においては、便宜上図３の矢印Ａの方向を「前方」とする。
パッド部６は、担持部２の開口部２ａより該担持部２に内装される部材であり、作業者が肩当て１を装着し、該肩当て１上に重量物を担持したときに、重量物が作業者の肩に食い込まないようにするためのものである。パッド部６を金属や硬質のプラスチックなど変形しない材料で構成した場合、重量物は肩に食い込まないが肩当て１から重量物が滑ってずれる場合がある。一方、パッド部６が柔らかすぎると重量物が肩に食い込むのを防止することができない。よって、パッド部６は適度に強度がある可撓性の材料であることが要求され、ポリウレタンやその他の樹脂、ゴムなど弾性的に変形しうる材料で構成される。
【００１５】
図７に示す如く、パッド部６の上面６ａは右側面６ｃ、左側面６ｄおよび前面６ｅに向かって緩やかに傾斜しており、ちょうど上面６ａの左右中央部が上方に隆起したような形状となっている。一方、下面６ｂの左右中央部は窪んでおり、該下面６ｂが作業者の肩形状になじむように成形される。
図３および図４に示す如く、上面６ａは担持部２内で作業者が担持する重量物側に対面する部位であり、側面視Ｖ字型の横湾曲溝８・８・８が、互いに略平行かつその長手方向が左右方向に略一致するように設けられている。一方、図６に示す如く、下面６ｂは担持部２内で作業者の肩に対面する部位であり、正面視Ｖ字型の縦湾曲溝９・９・９が、互いに略平行かつその長手方向が前後方向に略一致するように設けられている。
【００１６】
図４に示す如く、後面６ｆは肩当て１の担持部２にパッド部６が内装されたときに作業者の首と面する部位であり、作業者の首になじむように平面視で前面６ｅ側に凹んだ形状となっている。一方、前面６ｅはパッド部６を開口部２ａより担持部２に内装する時に容易となるように左右の角が丸く形成されている。
【００１７】
以上の如く構成することにより、肩当て１の担持部２にパッド部６が内装された状態において該パッド部６は作業者の肩形状によくフィットするとともに、作業中においても、パッド部６の上面６ａおよび下面６ｂにそれぞれ設けられた横湾曲部８および縦湾曲部９にてパッド部６は前後方向、左右方向ともに湾曲可能であり、作業者の肩の動きに柔軟に追従し、常に作業者の肩にフィットした状態を保持することが可能である。
また、パッド部６は作業者が重量物を担持したときにある程度弾性変形し、かつ作業者の肩に重量物が食い込まないように上下方向に所定の厚さを有している。さらにパッド部６が内装される担持部２は袋状に形成されていることから少なくとも上下方向に担持部２上面、パッド部６、担持部２下面の三層構造となっている。従って、本実施例の肩当て１を用いて重量物を担持した場合において、該重量物が直射日光による表面温度の上昇があっても、作業者の肩までは熱伝導はほとんど起こらず、作業に支障をきたすことがないとともに、作業者の快適性が保持されるのである。このとき、重量物の重さや表面温度に応じて担持部２にパッド部６を複数個内装しても良く、タオル片等の布を併せて内装しても良い。
また、本実施例では担持部２を袋状に構成し、該担持部２にパッド部６を内装したが、例えば、パッド部６の下面６ｂと担持部２の上面とを面ファスナーなどにより着脱可能に固定しても同様の効果を奏するので、担持部２へのパッド部６の固定方法は限定されない。
【００１８】
なお、本実施例においては横湾曲溝８および縦湾曲溝９の断面形状はＶ字型であったが、例えばＵ字型や矩形など他の形状でも良く、限定されない。また横湾曲溝８および縦湾曲溝９の本数は、単数または複数であって特に限定されず、パッド部６の材質や厚さ、担持する重量物の重量等に応じて適宜選択すればよい。
また、本実施例においては平面視で横湾曲溝８と縦湾曲溝９とが成す角度は９０度であるが、例えば６０度など横湾曲溝８と縦湾曲溝９とが略平行でない、すなわち長手方向が互いに異なっていればよく、限定されない。
また、本実施例では上面６ａ側に左右方向の横湾曲溝８・８・・・が設けられ、下面６ｂ側に前後方向の縦湾曲溝９・９・・・が設けられるが、逆に上面６ａ側に縦湾曲溝９を設け、下面６ｂ側に横湾曲溝８を設けても良い。
さらに、図８に示すパッド部の第二実施例であるパッド部１６の如く、外形は第一実施例であるパッド部６と略同じであるが、上面１６ａまたは下面１６ｂのいずれか一方に（図８では上面１６ａ側のみ）横湾曲溝２０と縦湾曲溝２１を併せた平面視格子状の溝を設けても良く、または上面１６ａと下面１６ｂの両面に、横湾曲溝２０と縦湾曲溝２１を併せた平面視格子状の溝を設けても良い。
また、図１１に示すパッド部の第三実施例であるパッド部２６の如く、外形は第一実施例であるパッド部６と略同じであるが、上面２６ａと下面２６ｂとを貫通して通気孔２７・２７・・・を穿設しても良い。該通気孔２７・２７・・・を穿設することにより、夏場の作業時における快適性が向上する。なお、通気孔２７・２７・・・の個数や形状、大きさは特に限定されないが、重量物が作業者の肩に食い込むのを防止し、かつ熱を遮断するというパッド部本来の要件を満たさなくなる場合があることから、あまり通気孔２７の数を多くしたり、通気孔２７を大きくしたりしないことが望ましい。
【００１９】
続いて、本発明の第二実施例である肩当て１１について図９および図１０を用いて説明する。
肩当て１１は主に、担持部１２、側部１３・１４、係止部１５およびパッド部６（パッド部６は第一実施例である肩当て１と共通）などからなる。
図９に示す如く、担持部１２は第一実施例における担持部２と略同様に、略長方形で内部が袋状に形成されるとともに、布や樹脂、ゴムなど、作業者の肩になじみやすい可撓性の材料で構成される。また担持部１２の四辺の内、一辺は開口部１２ａとなっており、該開口部１２ａより後述するパッド部６が内装される。
【００２０】
側部１３・１４は、担持部１２の開口部１２ａと隣り合う二辺に縫着、接着等の方法で取り付けられるか、または担持部１２と一体的に成形される略長方形の部材であり、担持部１２と略同様に布や樹脂、ゴムなど、作業者の肩になじみやすい可撓性の材料で構成される。図１０に示す如く、側部１３・１４は略同じ形状であり、開口部１２ａを上向きとしたときに担持部１２と側部１３・１４とを合わせたものはその形状が略左右対称である。
このように構成することにより、作業者は肩当て１１を右肩および左肩のどちらでも装着可能である。
なお、図１０において、略長方形の部材である側部１３における四隅の内、担持部１２と隣接しない上側の隅を角部１３ａ、担持部１２と隣接しない下側の隅を角部１３ｂとする。側部１４についても同様に角部１４ａ、角部１４ｂを定義する。
【００２１】
係止部１５は、その両端が側部１３・１４の角部１３ａ・１４ａに取り付けられる。該係止部１５は担持部１２と略同様に布や樹脂、ゴムなどで構成された紐または帯状の部材であり、長さ調整が可能に長さ調整部材１７が設けられる。また、係止部１５を伸縮可能なゴム帯やゴム紐などで構成した場合、長さ調整部材１７を省略しても良い。
そして、係止部１５は、例えば図９に示す如く肩当て１１が作業者の左肩に装着される場合には、作業者の胴体右側に巻回、当接させることにより肩当て１１を固定する。すなわち、係止部１５は、装着される方の肩から反対側の脇の下に通されて肩当て１１を作業者の肩に係止するのである。
このように構成することにより、肩当て１１は作業者が重量物を担持しているときにもずれることが無く、また肩当て１１を装着している方の脇の下は大きく開口した形となっており、作業を阻害することが無く作業性に優れる。
【００２２】
また、着脱式係止部１８は、その両端に着脱部材１８ａ・１８ａが設けられ、係止部１５と略同様に布や樹脂、ゴムなどで構成された紐または帯状の部材であり、長さ調整が可能に長さ調整部材１９が設けられる。着脱部材１８ａ・１８ａは側部１３の角部１３ｂおよび側部１４の角部１４ｂに係止可能に構成される。
該着脱係止部１８は、その両端において肩当て１１に対して着脱可能に構成されている。そのため、肩当て１１を作業者の右肩または左肩のどちらに装着しても作業者が着脱作業を行うのが容易な体の前面に一方の着脱部材１８ａが位置するので作業性に優れる。また、係止部１５と合わせてさらに肩当て１１の位置がずれにくくなる。さらに、着脱係止部１８は全幅を大きく構成しないことにより、肩当て１１を装着している方の腕や肩の動きを阻害することがない。
なお、着脱係止部１８を第一実施例（肩当て１）において使用してもよい。
【００２３】
また、第一実施例と同様に、パッド部６は作業者が重量物を担持したときにある程度弾性変形し、かつ作業者の肩に重量物が食い込まないように上下方向に所定の厚さを有している。さらにパッド部６が内装される担持部１２は袋状に形成されていることから少なくとも上下方向に担持部１２上面、パッド部６、担持部１２下面の三層構造となっている。従って、本実施例の肩当て１１を用いて重量物を担持した場合において、該重量物が直射日光による表面温度の上昇があっても、作業者の肩までは熱伝導はほとんど起こらず、作業に支障をきたすことがないとともに、作業者の快適性が保持されるのである。このとき、重量物の重さや表面温度に応じて担持部１２にパッド部６を複数個内装しても良く、タオル片等の布を併せて内装しても良い。
【００２４】
【発明の効果】
本発明は、以上のように構成したので、以下に示すような効果を奏する。
【００２５】
即ち、請求項１に示す如く、担持部と、パッド部と、一対の側部と、該側部間を連結する係止部とを備えるので、作業者の肩に重量物が食い込まず、かつ重量物表面温度が高くても作業者の肩は高温にならず、作業性に優れる。
【００２６】
請求項２に示す如く、前記一対の側部を左右略対称形状に構成したので、作業者は肩当てを右肩および左肩のどちらでも装着可能である。
【００２７】
請求項３に示す如く、作業者への装着時において、担持部が当接する作業者の肩と反対側の作業者胴体側面に係止部が巻回されるので、肩当てを装着している方の脇の下は大きく開口した形となっており、肩当てを装着している側の肩や腕の動きを阻害することが無く作業性に優れる。
【００２８】
請求項４に示す如く、前記係止部を長さ調整可能に構成したので、肩当ては作業者が重量物を担持しているときにもずれることが無く、作業性に優れる。
【００２９】
請求項５に示す如く、前記パッド部の上面と下面とにそれぞれ長手方向が異なる溝を設けたので、該パッド部は前後方向、左右方向ともに湾曲可能であり、作業者の肩の動きに柔軟に追従し、肩当ては常に作業者の肩にフィットした状態を保持することが可能である。

FIG. 11 is a plan view showing an embodiment, and FIG. 11 is a perspective view of a third embodiment of a pad portion.
[0011]
First, the overall structure of a shoulder pad 1 according to a first embodiment of the present invention will be described with reference to FIGS.
The shoulder pad 1 mainly includes a support portion 2, side portions 3.4, a locking portion 5, a pad portion 6, and the like.
As shown in FIG. 2, the support portion 2 has a substantially rectangular shape and the inside is formed in a bag shape, and is made of a flexible material such as cloth, resin, rubber, etc., which easily fits into the shoulder of the worker. One side of the four sides of the support portion 2 is an opening 2a, and a pad portion 6 described later is housed through the opening 2a.
[0012]
The side portions 3 and 4 are substantially triangular members that are attached to two sides adjacent to the opening 2a of the support portion 2 by sewing, bonding, or the like, or are formed integrally with the support portion 2, It is made of a flexible material, such as cloth, resin, rubber, etc., which is easy to fit into the shoulder of the worker, in substantially the same manner as the carrier 2. As shown in FIG. 2, the sides 3 and 4 have substantially the same shape, and when the opening 2a is directed upward, the shape of the combination of the carrier 2 and the sides 3 and 4 is substantially symmetrical. .
With this configuration, the worker can wear the shoulder pad 1 on either the right shoulder or the left shoulder.
[0013]
Both ends of the locking portion 5 are attached to the tip portions 3a and 4a of the side portions 3.4. The locking portion 5 is a string or band-like member made of cloth, resin, rubber, or the like, substantially in the same manner as the support portion 2, and is provided with a length adjusting member 7 capable of adjusting the length. When the locking portion 5 is made of a stretchable rubber band or rubber string, the length adjusting member 7 may be omitted.
When the shoulder pad 1 is attached to the left shoulder of the worker, for example, as shown in FIG. 1, the locking portion 5 is wound around the right side of the worker's torso to fix the shoulder pad 1. . That is, the locking part 5 is passed under the armpit on the opposite side from the shoulder to be mounted, and locks the shoulder pad 1 on the shoulder of the worker.
With such a configuration, the shoulder pad 1 does not shift when the operator is carrying a heavy object, and the armpits of the person wearing the shoulder pad 1 have a large opening. Thus, the workability is excellent without obstructing the movement of the shoulder and arm on the side where the shoulder rest 1 is mounted. Further, by setting the area of the side portions 3 and 4 to the minimum necessary size that allows the shoulder pad 1 to be locked without being displaced from the body of the worker, the worker feels heat even during use in summer. Excellent comfort without.
[0014]
Subsequently, the details of the pad section 6 which is the first embodiment of the pad section will be described with reference to FIGS. In the following description of the pad section 6, the direction of arrow A in FIG.
The pad portion 6 is a member provided inside the support portion 2 through the opening 2 a of the support portion 2. When the worker wears the shoulder pad 1 and holds a heavy object on the shoulder pad 1, the weight is reduced. This is to prevent things from getting into the worker's shoulder. When the pad portion 6 is made of a non-deformable material such as metal or hard plastic, the heavy object does not cut into the shoulder, but the heavy object may slip off the shoulder pad 1. On the other hand, if the pad portion 6 is too soft, it is impossible to prevent a heavy object from biting into the shoulder. Therefore, the pad portion 6 is required to be a flexible material having moderate strength, and is made of a material that can be elastically deformed, such as polyurethane, other resins, and rubber.
[0015]
As shown in FIG. 7, the upper surface 6a of the pad portion 6 is gently inclined toward the right side surface 6c, the left side surface 6d, and the front surface 6e, and has a shape in which the right and left central portions of the upper surface 6a are raised upward. ing. On the other hand, the left and right central portions of the lower surface 6b are concave, and the lower surface 6b is formed so as to conform to the shoulder shape of the worker.
As shown in FIGS. 3 and 4, the upper surface 6 a is a portion facing the side of the heavy object carried by the worker in the support portion 2, and the V-shaped laterally curved grooves 8, 8 are viewed from each other. It is provided so that it is parallel and its longitudinal direction substantially coincides with the left-right direction. On the other hand, as shown in FIG. 6, the lower surface 6 b is a portion facing the shoulder of the worker in the support portion 2, and the V-shaped vertical curved grooves 9, 9 are substantially parallel to each other and the longitudinal direction thereof. Are provided so as to substantially coincide with each other in the front-rear direction.
[0016]
As shown in FIG. 4, the rear surface 6f is a portion facing the worker's neck when the pad portion 6 is mounted on the support portion 2 of the shoulder pad 1, and the front surface 6e in a plan view is adapted to fit the worker's neck. It has a concave shape on the side. On the other hand, the left and right corners of the front surface 6e are rounded so that the pad portion 6 can be easily installed in the support portion 2 from the opening portion 2a.
[0017]
With the configuration described above, the pad portion 6 fits well to the shape of the shoulder of the worker when the pad portion 6 is mounted on the support portion 2 of the shoulder pad 1, and the pad portion 6 can be fitted even during the work. The pad portion 6 can bend both in the front-rear direction and the left-right direction with the horizontal bending portion 8 and the vertical bending portion 9 provided on the upper surface 6a and the lower surface 6b, respectively. It is possible to maintain a state fitted to the shoulder of the person.
The pad portion 6 is elastically deformed to some extent when the operator carries a heavy object, and has a predetermined thickness in the vertical direction so that the heavy object does not bite into the shoulder of the operator. Further, since the supporting portion 2 in which the pad portion 6 is provided is formed in a bag shape, the supporting portion 2 has a three-layer structure of an upper surface of the supporting portion 2, a pad portion 6, and a lower surface of the supporting portion 2 at least in the vertical direction. Therefore, when a heavy object is carried using the shoulder pad 1 of the present embodiment, even if the surface temperature of the heavy object rises due to direct sunlight, heat conduction hardly occurs to the worker's shoulder, and In addition, the comfort of the worker is maintained without any trouble. At this time, a plurality of pad portions 6 may be provided in the support portion 2 in accordance with the weight of the heavy object and the surface temperature, or a cloth such as a towel piece may be provided together.
Further, in the present embodiment, the support portion 2 is formed in a bag shape, and the pad portion 6 is provided inside the support portion 2. However, for example, the lower surface 6b of the pad portion 6 and the upper surface of the support portion 2 are attached and detached with a surface fastener. The same effect can be obtained even if the pad portion 6 is fixed as much as possible, and the method of fixing the pad portion 6 to the support portion 2 is not limited.
[0018]
