Abstract
Description
本発明は、真空吸引力を利用して壁面などの被吸着面に吸着される吸引具に関するものである。 The present invention relates to a suction tool that is attracted to a suction surface such as a wall surface using a vacuum suction force.
真空吸引力を高めて、吸引具を壁面などの被吸着面に強固に吸着させることのできる吸着具として、図6に示すものが知られている(特許文献1)。 As an adsorbing tool capable of increasing the vacuum suction force and firmly adsorbing the aspirating apparatus to a surface to be adsorbed such as a wall surface, one shown in FIG. 6 is known (Patent Document 1).
この従来例は、押圧盤51、吸盤52、ネジ軸53、ナット具54、真空壁用リング体55を備え、前記吸盤52と一体のネジ軸53を操作することにより、吸盤52の中央部を引上げて、被吸着面56との間に強制的に真空部57を作るものである。そして押圧盤51の周縁下面に取り付けたゲル状の真空壁用リング体55はこれらになじむよう変形して密着するので、前記真空部57の真空状態の維持能力が高いものとなって、吸引具を被吸着面56に強固に吸着させることができる。
しかしながら上記従来例は、押圧盤51の周縁下面にゲル状の真空壁用リング体55の上面を接着した構造となっているため、繰り返し吸着具を使用したとき、その接着部が剥がれ易いという問題がある。近年接着剤の性能の向上が著しいが、ゲルタイプのポリウレタンなどからなる真空壁用リング体55を硬質樹脂製の押圧盤51に強力かつ耐久性良く接着することは、現在の技術をもってしても容易ではない。そして長期繰返し使用によって、真空壁用リング体55の円周上の一部において、接着部が剥がれると、前記真空部57の真空状態の維持が困難になる。 However, the above conventional example has a structure in which the upper surface of the gel-like vacuum wall ring body 55 is bonded to the lower surface of the peripheral edge of the pressing plate 51, and therefore, when the suction tool is used repeatedly, the bonded portion is easily peeled off. There is. In recent years, the performance of adhesives has been remarkably improved, but it is possible to bond the vacuum wall ring body 55 made of gel type polyurethane or the like to the press plate 51 made of hard resin with high strength and durability even with the current technology. It's not easy. If the adhesive part is peeled off at a part of the circumference of the vacuum wall ring body 55 by repeated use over a long period of time, it becomes difficult to maintain the vacuum state of the vacuum part 57.
また上記従来例では、別途製作された押圧盤51と真空壁用リング体55とを、接着する工程が必要である。 Moreover, in the said prior art example, the process of adhere | attaching the press board 51 and the ring body 55 for vacuum walls separately manufactured is required.
本発明は、上記従来例の長期繰返し使用による真空状態の維持が困難になるという問題を解決できると共に、接着工程を省略して製造コストの低減を図ることができる吸着具を提供することを目的とする。 An object of the present invention is to provide an adsorber that can solve the problem that it is difficult to maintain a vacuum state due to long-term repeated use of the above-described conventional example, and that can reduce the manufacturing cost by omitting the bonding step. And
本発明は、上記目的を達成するため、押圧盤と、吸盤と、ゲル状リング体と、吸盤の中央部を引上げる引上げ手段とを備えた吸着具において、押圧盤の周縁部に、その周縁に沿って配された複数の上下貫通孔が設けられ、ゲル状リング体は、インサート成形により押圧盤の周縁部に一体成形されてなり、押圧盤周縁の下面に位置する真空壁形成部と、押圧盤周縁の上面に位置する係止部と、前記上下貫通孔内に充填されて前記真空壁形成部と前記係止部とを結合する結合部とからなることを特徴とする。 In order to achieve the above object, the present invention provides an adsorbing tool including a pressing plate, a suction cup, a gel-like ring body, and a lifting means for pulling up the central portion of the suction cup. A plurality of upper and lower through holes arranged along the gel ring body is integrally formed on the periphery of the press plate by insert molding, and a vacuum wall forming portion located on the lower surface of the press plate periphery, It is characterized by comprising a locking portion located on the upper surface of the peripheral edge of the pressing plate and a coupling portion that fills the upper and lower through holes and connects the vacuum wall forming portion and the locking portion.
本発明によれば、ゲル状リング体の真空壁形成部は、押圧盤の周縁に沿って配された複数の上下貫通孔に充填形成された連結部を介して、押圧盤周縁上面に位置する係止部に一体的に連結しているので、ゲル状リング体は押圧盤に強固に結合される。そして接着剤を用いた結合ではないので、吸着具の繰返し使用によっても、ゲル状リング体が剥がされるようなことは無く、耐久性の向上を図ることができる。また、インサート成形により、ゲル状リング体の成形とその押圧盤への結合を同時に行うことができ、従来例で必要であった接着工程を省略して、製造コストの低減を図ることができる。 According to the present invention, the vacuum wall forming part of the gel-like ring body is located on the upper surface of the press plate periphery via the connecting portions filled in the plurality of upper and lower through holes arranged along the periphery of the press plate. Since it is integrally connected to the locking portion, the gel-like ring body is firmly coupled to the pressing plate. And since it is not the coupling | bonding which used the adhesive agent, even if it uses an adsorption tool repeatedly, a gel-like ring body will not be peeled and durability can be aimed at. Also, by insert molding, the gel-like ring body can be molded and bonded to the pressing plate at the same time, and the manufacturing process can be reduced by omitting the bonding step required in the conventional example.
図示する実施例は、本発明をフック付き吸着具に適用した例に係るものである。 The illustrated embodiment relates to an example in which the present invention is applied to a hooked suction tool.

前記引上げネジ4は、硬質合成樹脂製であって、ネジ軸部4aとその下端に連なる皿部4bとからなる。前記吸盤2は、エラストマ製であって、中央部2aが盛り上がった円盤形に形成されている。この吸盤2は、前記引上げネジ4の皿部4bが、前記中央部2aに埋設されて一体化されるようにして、インサート成形で形成されている。 The pulling screw 4 is made of a hard synthetic resin and includes a screw shaft portion 4a and a plate portion 4b connected to the lower end thereof. The suction cup 2 is made of an elastomer and is formed in a disk shape with a raised central portion 2a. The suction cup 2 is formed by insert molding so that the plate portion 4b of the pulling screw 4 is embedded and integrated in the central portion 2a.
前記押圧盤1は、硬質合成樹脂製であって、平面視円形の伏せ碗形状に形成されている。図4、図5に詳細に示すように、押圧盤1は、中央上段部11、周辺下段部12、中央上段部11と周辺下段部12とを繋ぐテーパ状中間部13とからなる。中央上段部11は、その中心部に上下に貫通する円孔11aを備え、この円孔11aの周縁上面側に、ナット受け部11bが上方に向け突出するようにして形成されている。中央上段部11と周辺下段部12とは、上述のようにテーパ状中間部13によって連結されているが、このテーパ状中間部13と前記周辺下段部12との上面には放射状に走る8本の補強リブ14が互いに等間隔になるように形成されている。前記周辺下段部12は、その下面12aが平坦面となっており、その上面外周部に円環状の突条壁12bを有している。この突条壁12bの上面に前記補強リブ14の上面が面一となるように連なっている。また突条壁12bの外周側には係止部12cが形成さている。前記周辺下辺部12の突条壁12bの内側位置に、同一円周上に位置する16個の上下貫通孔15が、互いに等間隔を隔てて形成されている。すなわち、図5に示すように、前記周辺下段部12の左右一対の補強リブ14と前記突条壁12bとで囲まれる領域の夫々には、2個の上下貫通孔15が形成されている。 The pressing plate 1 is made of a hard synthetic resin, and is formed in a shape of a flat bowl in plan view. As shown in detail in FIGS. 4 and 5, the pressing plate 1 includes a central upper step portion 11, a peripheral lower step portion 12, and a tapered intermediate portion 13 that connects the central upper step portion 11 and the peripheral lower step portion 12. The center upper step part 11 is provided with a circular hole 11a penetrating vertically at the center part, and a nut receiving part 11b is formed on the upper surface of the peripheral edge of the circular hole 11a so as to protrude upward. The central upper step portion 11 and the peripheral lower step portion 12 are connected by the taper-shaped intermediate portion 13 as described above. The upper surface of the taper-shaped intermediate portion 13 and the peripheral lower step portion 12 runs radially. The reinforcing ribs 14 are formed at equal intervals. The lower peripheral step 12 has a flat lower surface 12a and an annular ridge wall 12b on the outer periphery of the upper surface. The upper surface of the reinforcing rib 14 is connected to the upper surface of the protruding wall 12b so as to be flush with each other. A locking portion 12c is formed on the outer peripheral side of the ridge wall 12b. Sixteen upper and lower through holes 15 located on the same circumference are formed at equal intervals in the inner position of the ridge wall 12b of the peripheral lower side portion 12. That is, as shown in FIG. 5, two upper and lower through holes 15 are formed in each of the regions surrounded by the pair of left and right reinforcing ribs 14 of the peripheral lower step portion 12 and the protruding wall 12b.
前記ゲル状リング体3は、スチレン系エラストマを素材として、前記押圧盤1の周辺下段部12にインサート成形により、一体的に形成されている。そしてゲル状リング体3は、図4、図5に示すように、前記周辺下段部12の下面に位置する真空壁形成部31と、前記周辺下段部12の上面に位置する係止部32と、前記上下貫通孔15内に充填されて前記真空壁形成部31と前記係止部32とを結合する結合部33とからなるように、インサート成形されている。 The gel-like ring body 3 is integrally formed by insert molding on the lower peripheral portion 12 of the press disc 1 using a styrene elastomer as a material. As shown in FIGS. 4 and 5, the gel-like ring body 3 includes a vacuum wall forming portion 31 positioned on the lower surface of the peripheral lower step portion 12, and a locking portion 32 positioned on the upper surface of the peripheral lower step portion 12. The upper and lower through-holes 15 are insert-molded so as to include a coupling portion 33 that couples the vacuum wall forming portion 31 and the locking portion 32.
前記真空壁形成部31は、円環状に形成され、その横断面は、図4に示すように、下面が平坦な外周壁部31aと、下面がテーパ面となる内周壁部31bとを有して、上面31cが前記周辺下段部12の下面12aに密着している。前記係止部32は、図5に示すように放射状の補強リブ14によって区画される8領域に分かれて形成され、夫々の係止部32の下面32aは前記周辺下段部12の上面に密着すると共に、夫々の係止部32の外周側面32bは前記突条壁12bの内周側面に密着している。そして前記真空壁形成部31と各係止部32は夫々1対の結合部33により結合され、またインサート成形の冷却時におけるスチレン系エラストマの収縮により、ゲル状リング体3は前記周辺下段部12を挟圧するようにして、強固に押圧盤1に固着されている。 As shown in FIG. 4, the vacuum wall forming portion 31 is formed in an annular shape. As shown in FIG. 4, the vacuum wall forming portion 31 has an outer peripheral wall portion 31a having a flat lower surface and an inner peripheral wall portion 31b having a lower surface tapered. Thus, the upper surface 31 c is in close contact with the lower surface 12 a of the peripheral lower step portion 12. As shown in FIG. 5, the locking portion 32 is divided into eight regions defined by the radial reinforcing ribs 14, and the lower surface 32 a of each locking portion 32 is in close contact with the upper surface of the peripheral lower step portion 12. At the same time, the outer peripheral side surface 32b of each locking portion 32 is in close contact with the inner peripheral side surface of the protruding wall 12b. The vacuum wall forming portion 31 and each locking portion 32 are connected by a pair of connecting portions 33, respectively, and the gel-like ring body 3 is caused to contract the peripheral lower step portion 12 by contraction of the styrene elastomer during cooling of the insert molding. Is firmly fixed to the pressing plate 1 in such a manner as to sandwich the pressure.
前記ナット具5は、硬質合成樹脂製であって、キャップ部5aと、このキャップ部5aの中心部から下方に突出するネジ筒部5bとを有している。ネジ筒部5bはその内周に前記引上げネジ4のネジ軸部4aに螺合する雌ネジ5cが形成され、その下端部5dは押圧盤1の前記ナット受け部11bに収納されている。 The nut member 5 is made of hard synthetic resin, and has a cap part 5a and a screw cylinder part 5b protruding downward from the center part of the cap part 5a. A female screw 5c is formed on the inner periphery of the screw cylinder portion 5b so as to be screwed into the screw shaft portion 4a of the pulling screw 4, and a lower end portion 5d thereof is housed in the nut receiving portion 11b of the pressing plate 1.
前記カバー体6は、硬質合成樹脂製であって、中央に円形開口6aを有する朝顔形状に形成されたものである。カバー体6の外周部6bは、押圧盤1の係止部12cに、係合する係合部6cを有し、内周部6dにはフック線材収容部6eが形成されている。図4に示すように、カバー体6は押圧盤1に組み付けられる。すなわちカバー体6の円形開口6aに押圧盤1のナット受け部11bが挿通され、その内周部6dが押圧盤1の中央上段部11上に着座し、前記係合部6cが前記係止部12cに無理嵌め状に係合して前記外周部6bを押圧盤1の周辺下段部12に結合することにより、カバー体6は押圧盤1に組み付けられる。 The cover body 6 is made of a hard synthetic resin and is formed in a morning glory shape having a circular opening 6a in the center. The outer peripheral portion 6b of the cover body 6 has an engaging portion 6c to be engaged with the engaging portion 12c of the pressing plate 1, and a hook wire accommodating portion 6e is formed on the inner peripheral portion 6d. As shown in FIG. 4, the cover body 6 is assembled to the pressing plate 1. That is, the nut receiving portion 11b of the pressing plate 1 is inserted into the circular opening 6a of the cover body 6, its inner peripheral portion 6d is seated on the central upper step portion 11 of the pressing plate 1, and the engaging portion 6c is the locking portion. The cover body 6 is assembled to the pressing plate 1 by engaging the outer peripheral portion 6 b with the lower peripheral step portion 12 of the pressing plate 1 by forcibly engaging with 12 c.
前記引上げネジ4のネジ軸部4aは、前記押圧盤1の円孔11aを挿通して上方に突出し、前記ナット具5のネジ筒部5bに螺合される。ナット具5を所定方向に回転させると、ネジ筒部5bの下端面が押圧盤1の中央上段部11に当接していることにより、引上げネジ4を引上げて、吸盤2の中央部2aを図4に示すように、引上げることができる。このため被吸着面41と吸盤2との間に真空部42が形成される。前記引上げネジ4の引上げ時に、押圧盤1の周辺下段部12から真空壁形成部31を通じて、吸盤2の周辺部2bに押圧力が加わり、これを被吸着面41に押し付ける。また真空壁形成部31自身も被吸着面41に押し付けられ、これがゲルタイプのものであることから、被吸着面41に凹凸や傷がある場合でも、これらになじむようにして変形し密着するので、前記真空部42の真空状態を極めて高度に維持することができる。 The screw shaft portion 4 a of the pulling screw 4 is inserted through the circular hole 11 a of the pressing plate 1 and protrudes upward, and is screwed into the screw cylinder portion 5 b of the nut member 5. When the nut tool 5 is rotated in a predetermined direction, the lower end surface of the screw cylinder portion 5b is in contact with the center upper step portion 11 of the pressing plate 1, so that the pulling screw 4 is pulled up so that the central portion 2a of the suction cup 2 is illustrated. As shown in FIG. Therefore, a vacuum part 42 is formed between the attracted surface 41 and the suction cup 2. When the pulling screw 4 is pulled up, a pressing force is applied to the peripheral portion 2 b of the suction cup 2 from the lower peripheral step portion 12 of the pressing plate 1 through the vacuum wall forming portion 31, and this is pressed against the attracted surface 41. Further, since the vacuum wall forming part 31 itself is also pressed against the attracted surface 41 and this is a gel type, even if the attracted surface 41 has irregularities and scratches, it deforms and adheres to these so The vacuum state of the vacuum part 42 can be maintained at a very high level.
前記フック7は、その基端側のリング部7aが前記カバー体6のフック線材収容部6e内に収容され、その弾性縮径力で押圧盤1のナット受け部11bの外周に取り付けられている。 The hook 7 has a ring portion 7a on the base end side accommodated in the hook wire accommodating portion 6e of the cover body 6, and is attached to the outer periphery of the nut receiving portion 11b of the pressing plate 1 by its elastic diameter reducing force. .
本発明は上記実施例に示す外、種々の態様に構成することができる。例えば上記実施例では、引上げネジ4とナット具5とで、吸盤2の中央部2aを引上げる引上げ手段を構成しているが、このようなネジ式の引上げ手段に代えて、テコを利用したレバー式引上げ手段等を採用することができる。 The present invention can be configured in various modes other than those shown in the above embodiments. For example, in the above embodiment, the pulling screw 4 and the nut member 5 constitute the pulling means for pulling up the central portion 2a of the suction cup 2. However, instead of such a screw-type pulling means, a lever is used. A lever-type pulling means or the like can be employed.
本発明は、フック付き吸着具の外、種々の用途の吸着具として利用することができる。 The present invention can be used as an adsorbent for various uses in addition to an adsorber with a hook.
