There are many cases where work is done with knees mainly during tile work, interior flooring, interior cleaning work, and farm work. In such a case, various types of knee protectors have been proposed in order to protect the knee and prevent the clothes from being damaged. For example, Patent Document 1 discloses a knee brace that is formed in a cloth-like cylinder with a cushion material sewed thereon and is attached to a knee portion. Patent Document 2 includes a cushioning sheet material that is formed into an appropriate shape. An invention of a knee pad that is detachable using a fastener is disclosed.
Further, in Patent Document 3, a connecting portion is provided at the center of the upper end of a knee pad cushion material to be attached to the knee by bands provided at two upper and lower portions, and one end of a thin elastic material is connected to the connecting portion and the thin plate. An invention is disclosed in which a winding elastic storage case is fixed to a waist band 6 and a cushioning sheet material is always pulled upward.
Utility Model Registration No. 3109462 JP-A-10-46411 JP 2007-113127 A

特許文献1や2に開示されているような、従来の膝用プロテクタでは、作業中に位置ずれを起こすことが多い。特に、歩行や膝の曲げ伸ばしによってプロテクタが上下にずれることが多く、頻繁に位置を直しながら作業を進める必要があった。また、特許文献3に開示されるように、常時プロテクタを上方に引き上げる薄板状弾性材を設けるものでは、薄板状弾性材そのものが作業の邪魔になるとともに、姿勢によって薄板状弾性材の引き上げ力が変化する他、プロテクタが上方に引き上げられてしまい所定の位置を維持することができない欠点があった。   Conventional knee protectors such as those disclosed in Patent Documents 1 and 2 often cause misalignment during work. In particular, the protector often shifts up and down due to walking or bending and stretching of the knee, and it was necessary to work while frequently correcting the position. In addition, as disclosed in Patent Document 3, in the case of providing a thin plate-like elastic material that always pulls the protector upward, the thin plate-like elastic material itself obstructs the work, and the pull-up force of the thin plate-like elastic material depends on the posture. In addition to the change, the protector is lifted upward, and the predetermined position cannot be maintained.

上記、従来技術の欠点に鑑み本発明は、作業のために膝をつく姿勢や立ち上がりを頻繁に繰り返す場合や、装着した状態で歩行しても位置ずれを生じにくい膝用プロテクタを実現することを目的とするものである。   In view of the above-mentioned drawbacks of the prior art, the present invention realizes a knee protector that is unlikely to be misaligned even when walking with the knee mounted or standing frequently for work or when worn. It is the purpose.

上記目的を達成するため、請求項1記載の発明は、膝用プロテクタを、膝を保護する強度と保形性を備えたカップ部1と、該カップ部1を膝に装着するための締め紐3などの係止手段と、カップ部1の内面に配置するクッション性を備え、膝全体を覆う大きさのパッド部2で構成する。パッド部は上下二分割とし、上パッド部2aを前記カップ部2に固定するとともに、上パッド部2aと下パッド部2bを伸縮性連結部材4で連結する。   In order to achieve the above object, the invention according to claim 1 is directed to a knee protector comprising a cup portion 1 having strength and shape retention for protecting the knee, and a tightening string for attaching the cup portion 1 to the knee. 3 and the like, and a cushion portion disposed on the inner surface of the cup portion 1, and the pad portion 2 having a size covering the entire knee. The pad portion is divided into upper and lower parts, the upper pad portion 2a is fixed to the cup portion 2, and the upper pad portion 2a and the lower pad portion 2b are connected by the elastic connecting member 4.

さらに、カップ部1の内面に配置する二分割されたパッド部2は、上パッド部2aを膝頭部分よりも上部を覆う細幅とし、下パッド部2bを膝頭部分の表面を覆う広幅に形成する。Furthermore, the pad part 2 divided into two parts arranged on the inner surface of the cup part 1 is formed so that the upper pad part 2a is narrower so as to cover the upper part than the kneecap part, and the lower pad part 2b is formed wide so as to cover the surface of the kneecap part. .

請求項2記載の発明は、前記請求項1記載の発明において、カップ部1の内面に配置する二分割されたパッド部2は、上パッド部2aと下パッド部2b を左右両端部で連結するとともに、中央部において伸縮性連結部材4で連結することである。According to the second aspect of the present invention, in the first aspect of the present invention, the two-part pad portion 2 disposed on the inner surface of the cup portion 1 connects the upper pad portion 2a and the lower pad portion 2b at both left and right end portions. And it is connecting with the elastic connection member 4 in a center part.

請求項1記載の本発明によれば、膝部分を保護するカップ部1を係止手段によって所定位置に係止させる。その状態で膝をつく姿勢から立ち上がる動作を繰り返す他、歩行の場合に膝の表面は上下方向に伸縮を繰り返す。このとき、膝表面の伸縮に対応してパッド部2の上パッド部2aと下パッド部2bが別個に移動する。具体的には係止手段によって係止されている上パッド部2aは膝上部の定位置に装着された状態で安定し、膝表面の伸縮に従って下パッド部2bが上下動をし、伸縮性連結部材4によって元の位置に復帰する。このようにして、各種動作による膝表面の伸縮を下パッド部2bの上下動によって吸収し、膝用プロテクタ全体の移動が防止される。   According to the first aspect of the present invention, the cup portion 1 that protects the knee portion is locked at a predetermined position by the locking means. In this state, in addition to repeating the action of standing up from a kneeling posture, the surface of the knee repeatedly expands and contracts in the vertical direction when walking. At this time, the upper pad portion 2a and the lower pad portion 2b of the pad portion 2 move separately corresponding to the expansion and contraction of the knee surface. Specifically, the upper pad portion 2a locked by the locking means is stable in a state where it is mounted at a fixed position on the upper part of the knee, and the lower pad portion 2b moves up and down according to the expansion and contraction of the knee surface. The member 4 returns to the original position. In this way, the expansion and contraction of the knee surface due to various operations is absorbed by the vertical movement of the lower pad portion 2b, and movement of the entire knee protector is prevented.

さらに、各種動作によって膝を伸縮させる場合、膝のほぼ中心に位置する膝頭部分の表面の伸縮が大きい。したがって、膝表面の大きく伸縮する膝頭部分の表面を、上パッド部2aに対して自由に上下方向に移動する下パッド部2bによって覆う。そのため、係止具によって定位置に係止されているカップ部1及び上パッド部2aに対して上下方向の力が作用せず、膝プロテクタをより安定させることができる。Furthermore, when the knee is extended and contracted by various operations, the expansion and contraction of the surface of the kneecap portion located substantially at the center of the knee is large. Therefore, the surface of the kneecap portion that greatly expands and contracts on the knee surface is covered by the lower pad portion 2b that freely moves in the vertical direction with respect to the upper pad portion 2a. Therefore, the vertical force does not act on the cup portion 1 and the upper pad portion 2a that are locked in place by the locking tool, and the knee protector can be further stabilized.

請求項2記載の発明によれば、請求項1に記載の発明を実施する上において、膝表面の伸縮にともなって下パッド2bが上下に移動する際、上パッド2aと下パッド2bの左右両端部が連結されているため、中央部のみが上下に移動する。すなわち、上パッド2aと下パッド2bは両端を支点としてパクパクと口を開けるように動く。この動きは、膝関節の回動運動と一致するため、膝の自然な動きを実現するとともに、上パッド2aと下パッド2bの正常な位置関係を維持し、快適な装着状態を実現する効果がある。According to the second aspect of the invention, when the lower pad 2b moves up and down as the knee surface expands and contracts, the left and right ends of the upper pad 2a and the lower pad 2b are implemented. Since the parts are connected, only the central part moves up and down. That is, the upper pad 2a and the lower pad 2b move so as to open their mouths with both ends as fulcrums. Since this movement coincides with the rotational movement of the knee joint, natural movement of the knee is achieved, and the normal positional relationship between the upper pad 2a and the lower pad 2b is maintained, and a comfortable wearing state is achieved. is there.

以下、本発明に係る膝用プロテクタの好ましい実施形態を添付の図面に基いて説明する。図1は斜視図、図2は正面図、図3は図2のIII−III線断面図、図4はパッド部のみの展開図である。   Hereinafter, preferred embodiments of a knee protector according to the present invention will be described with reference to the accompanying drawings. 1 is a perspective view, FIG. 2 is a front view, FIG. 3 is a sectional view taken along line III-III in FIG. 2, and FIG.

図1、図2に示す実施形態の膝用プロテクタは、膝を保護する強度と保形性を備えたカップ部1と、カップ部1を膝に装着するための締め紐3と、カップ部1の内面に配置するクッション性を備え、膝全体を覆う大きさのパッド部2で構成している。カップ部1は、合成樹脂材で、例えば球面あるいは椀形状であって、膝頭部分が自然に入り込むような形状に成形する。そして、膝をついたときに接地する中央部に、一段と高い接地部5を形成している。この接地部5は、図2に示す正面図において横長の楕円形に現れている。   The knee protector of the embodiment shown in FIG. 1 and FIG. 2 includes a cup part 1 having strength and shape retention for protecting the knee, a tightening string 3 for attaching the cup part 1 to the knee, and a cup part 1. The pad portion 2 is provided with a cushioning property to be disposed on the inner surface of the pad and has a size that covers the entire knee. The cup portion 1 is a synthetic resin material, for example, a spherical surface or a heel shape, and is formed into a shape that allows the kneecap portion to naturally enter. And the higher grounding part 5 is formed in the center part grounded when a knee is put. The grounding portion 5 appears in a horizontally long oval shape in the front view shown in FIG.

カップ部1の内面には、クッション性を備え膝全体を覆う大きさのパッド部2を配置している。パッド部2は、膝を保護するクッション性と外表面の強度を維持するものが好ましく、例えば図3に示すように、発泡材6の表面に合成樹脂製シート材7を貼着した積層材を使用する。パッド部2の外周は、縁テープ8を縫着してある。   On the inner surface of the cup portion 1, a pad portion 2 having a cushioning property and covering the entire knee is disposed. The pad portion 2 is preferably one that maintains cushioning properties for protecting the knee and strength of the outer surface. For example, as shown in FIG. 3, a laminated material in which a synthetic resin sheet material 7 is adhered to the surface of the foam material 6 is used. use. An edge tape 8 is sewn on the outer periphery of the pad portion 2.

カップ部1の内面に配置するパッド部2は上下二分割とし、上パッド部2aをカップ部1に固定するとともに、上パッド部2aと下パッド部2bを伸縮性連結部材4で連結している。カップ部1と上パッド部2aを固定するには、左右両側と上部の三箇所を鋲9によって固定している。このとき、左右両側を固定するに際して、締め紐3の右片3a及び左片3bの端部をそれぞれ鋲によって固定することによって、カップ部1に締め紐3を取り付けるようにしている。   The pad part 2 arranged on the inner surface of the cup part 1 is divided into two parts, and the upper pad part 2a is fixed to the cup part 1, and the upper pad part 2a and the lower pad part 2b are connected by the elastic connecting member 4. . In order to fix the cup part 1 and the upper pad part 2a, the left and right sides and the upper part are fixed by the hooks 9. At this time, when the left and right sides are fixed, the end portions of the right piece 3a and the left piece 3b of the tightening string 3 are fixed with scissors, so that the tightening string 3 is attached to the cup portion 1.

締め紐3の構造は、膝部分に着脱自在に取り付けることができるものであればどのような係止手段であってもよい。図示実施形態においては、締め紐3として扁平な伸縮性ベルトを利用し、長寸法の右片3aの先端に係止具の雄片10を、短寸法の左片3bの先端に係止具の雌片11を取り付けることによって、ワンタッチで容易に着脱することができるようにしている。
上記構成によって、カップ部1を膝の正面に位置させ、長寸法の右片3aを膝の裏側に巻回させて先端の雄片10を左片3bの先端に取り付けた雌片11に係止させることによって容易に着脱することができる。このとき、係止手段である締め紐3は、図5に示すように、膝の曲げ伸ばしに影響されにくい、膝の直上部分において締め紐3によって締め付け固定する。
The fastening strap 3 may be any locking means as long as it can be detachably attached to the knee portion. In the illustrated embodiment, a flat elastic belt is used as the strap 3, and the male piece 10 of the locking tool is attached to the tip of the long right piece 3 a and the locking piece is attached to the tip of the short left piece 3 b. By attaching the female piece 11, it can be easily attached and detached with one touch.
With the above configuration, the cup 1 is positioned in front of the knee, the long right piece 3a is wound around the back of the knee, and the male piece 10 at the tip is locked to the female piece 11 attached to the tip of the left piece 3b. Can be easily attached and detached. At this time, as shown in FIG. 5, the tightening string 3 as the locking means is fastened and fixed by the tightening string 3 at a portion directly above the knee that is not easily affected by bending and stretching of the knee.

上パッド部2aと下パッド部2bは、伸縮性連結部材4で連結する。上パッド部2aと下パッド部2bを連結する伸縮性連結部材4は、例えばバランスの取れる複数位置というように、どの位置で連結するものであってもよい。しかしながら、図示実施形態では、上パッド2aと下パッド2bは、左右両端部において縁テープ8を利用して連結するとともに、中央部の一箇所においてのみ広幅の伸縮性連結部材4で連結している。伸縮性連結部材4を広幅とすることによって、捩れ力が発生するようなことがなく、安定する。   The upper pad portion 2a and the lower pad portion 2b are connected by the stretchable connecting member 4. The stretchable connecting member 4 that connects the upper pad portion 2a and the lower pad portion 2b may be connected at any position, for example, a plurality of balanced positions. However, in the illustrated embodiment, the upper pad 2a and the lower pad 2b are connected using the edge tape 8 at both left and right ends, and are connected by the wide stretchable connecting member 4 only at one central portion. . By making the stretchable connecting member 4 wide, a twisting force is not generated and it is stable.

膝の曲げ伸ばしによって大きく伸縮するのは、膝の中央部分であることから、図示例のように上パッド部2aと下パッド部2bの両端部が連結され、中央部において伸縮性連結部材4によって連結することによって、上パッド部2aと下パッド部2bはより自然な状態で接離を繰り返す。すなわち、カップ部1及び上パッド部2aは膝の定位置に安定的に装着された状態で、膝の曲げ伸ばしによって下パッド2bが上下に移動する。したがって、しゃがみ込みと立ち上がり、あるいは歩行による膝の屈伸が繰り返されても、プロテクタは位置ずれを生じることがなく、安心して使用することができる。   Since it is the center part of the knee that greatly expands and contracts by bending and stretching the knee, both ends of the upper pad portion 2a and the lower pad portion 2b are connected as shown in the example, and the elastic connecting member 4 is connected at the center portion. By connecting, the upper pad portion 2a and the lower pad portion 2b repeat contact and separation in a more natural state. That is, the lower pad 2b moves up and down by bending and stretching the knee while the cup portion 1 and the upper pad portion 2a are stably mounted at the fixed positions of the knee. Therefore, even if the squatting and standing up or the knee is bent and stretched by walking repeatedly, the protector can be used with confidence without causing a positional shift.

バッド部2は、上パッド部2aと下パッド部2bに分割する。二分割の分割形状は、図4の展開図に示すように下パッド部2bの中央部を山形に上方に膨らむ大きな広幅形状とし、上パッド部2aを細幅に形成している。この形状とすることによって、膝の膝頭部分のほぼ全体を下パッド部2bによって覆うことができる。この形状とすることによって、図6に示すように、膝の屈伸によって伸縮をする膝頭を中心とする部分全体を下パッド部2bによって覆うことができる。   The pad portion 2 is divided into an upper pad portion 2a and a lower pad portion 2b. As shown in the development view of FIG. 4, the two-divided shape is a large wide shape in which the central portion of the lower pad portion 2b swells upward in a mountain shape, and the upper pad portion 2a is formed narrow. By adopting this shape, almost the entire kneecap portion of the knee can be covered with the lower pad portion 2b. By adopting this shape, as shown in FIG. 6, the entire portion centering on the kneecap that expands and contracts by bending and stretching the knee can be covered with the lower pad portion 2b.

すなわち、膝用プロテクタを装着した立位状態では、図6に示すように膝頭部分を下パッド2bによって覆い、伸縮性連結部材4は縮んだ状態である。図6に示す状態から、歩行などのために膝が曲げられると、図7に示すように膝頭部分の表面が矢印で示すように下方に移動する。それにともなって、下パッド部2bも下方に移動し、伸縮性連結部材4は伸びた状態となる。膝を伸ばすと、伸縮性連結部材4によって下パッド2bは引き上げられ、図6に示す元の位置に復帰する。   That is, in the standing state with the knee protector attached, the kneecap portion is covered with the lower pad 2b as shown in FIG. 6, and the stretchable connecting member 4 is in a contracted state. When the knee is bent for walking or the like from the state shown in FIG. 6, the surface of the kneecap portion moves downward as shown by the arrow as shown in FIG. Accordingly, the lower pad portion 2b is also moved downward, and the stretchable connecting member 4 is in an extended state. When the knee is extended, the lower pad 2b is pulled up by the elastic connecting member 4 and returns to the original position shown in FIG.

以上述べた、本発明に係る図示実施形態の膝用プロテクタを装着して、タイル工事、内装床貼り、内装清掃作業及び農作業などを行うに際し、膝をついて作業を行う場合は、カップ部1の接地部5が地面についた状態となり、カップ部1及びパッド部2を介して膝をつくことになり、膝をしっかりとガードする。そして、立ち上がって移動する場合など膝の曲げ伸ばしを伴う動作によってもカップ部1やパッド部2が膝に対して移動することがなく、常に同じ装着状態を維持し、作業を繰り返し行うことができる。   When the above-described knee protector of the illustrated embodiment according to the present invention is mounted and the work is performed with the knees when performing tile work, interior floor bonding, interior cleaning work, agricultural work, etc., The grounding portion 5 is in contact with the ground, and the knee is attached via the cup portion 1 and the pad portion 2 to firmly guard the knee. The cup part 1 and the pad part 2 do not move relative to the knee even when the knee is bent and stretched, such as when standing up and moving, so that the same wearing state can always be maintained and the operation can be repeated. .
