Description
本発明は、靴のヒール底部に装着されるトップリフトに関する。
The present invention relates to a top lift attached to the heel bottom of a shoe.
従来、靴のヒール本体を保護する、または接地した際の衝撃緩和を目的として、ヒール本体の底部にトップリフトが装着されている。トップリフトは、靴の使用により摩耗または損傷するため、適宜新たなトップリフトと交換されて靴の長期使用が図られている。
Conventionally, a top lift has been attached to the bottom of the heel body for the purpose of protecting the heel body of the shoe or reducing the impact when it contacts the ground. Since the top lift is worn or damaged by the use of shoes, the top lift is appropriately replaced with a new top lift for long-term use of the shoes.
一般的にトップリフトは、ゴムなどの軟質部材からなり、釘、ネジ、または接着剤により靴のヒール本体の底部に固定されている。よって、トップリフトを交換する際には、まずカッターやペンチ等の工具を用いて摩耗又は損傷したトップリフトをヒール本体から引き離し、新たなトップリフトをヒール本体の底部に再度、釘、ネジまたは接着剤を用いて固定する方法が一般的にとられている。この新たなトップリフトをヒール本体の底部にしっかりと固定する作業は、熟練した技術や特殊な工具を必要とするため、靴の修理店や販売店に靴を持参してトップリフトを交換しているのが実情であった。そこで近年、特殊な工具を必要とせずに交換作業を容易に行えるトップリフトが種々提案されている。
Generally, the top lift is made of a soft material such as rubber and is fixed to the bottom of the heel body of the shoe by a nail, a screw, or an adhesive. Therefore, when replacing the top lift, first use a tool such as a cutter or pliers to pull away the worn or damaged top lift from the heel body, and then attach the new top lift to the bottom of the heel body again with nails, screws, or glue. A method of fixing using an agent is generally taken. The work of firmly fixing this new top lift to the bottom of the heel body requires skilled techniques and special tools, so bring your shoes to a shoe repair shop or dealer and replace the top lift. It was the actual situation. Therefore, in recent years, various top lifts have been proposed that can be easily replaced without requiring a special tool.
例えば、特許文献１には、ヒール本体の底部に設けられた取付け孔に挿入される棒状体を、リフト本体の上面に立設し、棒状体の基部に窪みを設けてトップリフト交換修理時に生じたバリや研磨屑を窪みに収容させ、交換作業の効率を向上させたトップリフトが先に提案されている。
For example, in Patent Document 1, a rod-shaped body to be inserted into a mounting hole provided at the bottom of a heel body is erected on the upper surface of the lift body, and a recess is formed in the base of the rod-shaped body. A top lift has been previously proposed in which burrs and polishing debris are accommodated in the recesses to improve the efficiency of replacement work.
また例えば、特許文献２には、ヒール本体内に設けられた縦長の金属製パイプに、リフト本体の上面に立設した取付ピンを挿嵌するよう構成されたトップリフトが開示されている。
Further, for example, Patent Document 2 discloses a top lift configured to insert a mounting pin erected on an upper surface of a lift body into a vertically long metal pipe provided in the heel body.
特許文献１に記載されたトップリフトは、ヒール本体に底面側から穿設された取付け孔に、リフト本体の上面に設けられた棒状体を挿入し、取付け孔と棒状体の密着力によりトップリフトをヒール本体に固定させている。そのため、取付け孔の孔径が、棒状体の外径とほぼ同径もしくは僅かに小径に加工しなければ密着力が得られず、各種の靴に合わせて素人が取付け孔を精度よく加工することは困難であった。
In the top lift described in Patent Document 1, a bar-like body provided on the upper surface of the lift body is inserted into an attachment hole formed in the heel body from the bottom surface side, and the top lift is brought about by the adhesion between the attachment hole and the rod-like body. Is fixed to the heel body. Therefore, if the hole diameter of the mounting hole is not processed to the same or slightly smaller diameter than the outer diameter of the rod-like body, adhesion force cannot be obtained, and amateurs can accurately process the mounting hole according to various shoes. It was difficult.
また、特許文献２に記載されたトップリフトは、あらかじめヒール本体内に金属製パイプを設ける必要があるため、金属製パイプが備えられていないヒールには適用できず、各種の靴に使用することができなかった。
In addition, since the top lift described in Patent Document 2 needs to be provided with a metal pipe in the heel body in advance, it cannot be applied to a heel that is not provided with a metal pipe and should be used for various shoes. I could not.
本発明は、上記のような従来技術の課題に鑑みなされたものであり、靴のヒール本体に装着されるトップリフトに関し、各種の靴に適用可能で、トップリフトの交換作業が容易に行える交換用トップリフトを提供することを目的とする。

リフト本体１２は、リフト本体１２の上方に向けて固定ピン１１が突出した状態となるよう、固定ピン１１の基端部に設けられている。リフト本体１２は、ヒール本体の底部を保護するもので、そのサイズや形状は、使用する靴のヒール本体２に応じて適宜選択され、図示した形状に限定されるものではない。また、リフト本体１２の下面は地面に接するため、リフト本体１２の下面に滑り止め加工が施されても良い。リフト本体１２は、一般的にトップリフトに使用される耐摩耗性、防滑性、耐衝撃性、防音性等を有する素材が用いられ、例えば、合成樹脂材、合成又は天然のゴム材、及びこれらを組合せた素材が用いられる。
The lift body 12 is provided at the base end portion of the fixing pin 11 so that the fixing pin 11 protrudes upward from the lift body 12. The lift main body 12 protects the bottom of the heel main body, and the size and shape thereof are appropriately selected according to the heel main body 2 of the shoe to be used, and are not limited to the illustrated shapes. Further, since the lower surface of the lift body 12 is in contact with the ground, the lower surface of the lift body 12 may be subjected to anti-slip processing. The lift body 12 is made of a material having wear resistance, slip resistance, impact resistance, sound resistance, etc., generally used for a top lift. For example, a synthetic resin material, a synthetic or natural rubber material, and these A combination of materials is used.
尚、上述した固定ピン１１とリフト本体１２は、例えば樹脂材の射出成型により一体的に形成しても良く、或いは、別体に形成し夫々を固着して一体としても良い。
The fixing pin 11 and the lift body 12 described above may be formed integrally by, for example, injection molding of a resin material, or may be formed separately and fixed together to be integrated.
拡張ボルト１３は、いわゆる寸切りボルト（「全ネジ」や「スタッド」などとも称される）とも呼ばれ、円柱形状を有し、軸に沿って均一なピッチのネジ山が周面全長に亘って形成されている。拡張ボルト１３の端部には、六角レンチ（図示せず）が嵌合する凹部１３１が形成されている。拡張ボルト１３は、その雄ネジ外径Ｄ３が雌ネジ内径Ｄ２と同径もしくはわずかに小径、かつＤ３＞Ｄ１を満たす雄ネジ外径とされている。凹部１３１は、固定ピン１１の内周に形成された雌ネジ部１１３に拡張ボルト１３を螺合させる際に、六角レンチ、マイナスドライバー、又はプラスドライバーなどの一般的な締結具が嵌合するものであり、その形状は、各種締結具に適応した形状であれば良く、図示した形状に限定するものではない。

The recess 131 is fitted with a general fastener such as a hexagon wrench, a flat-blade screwdriver, or a flat-blade screwdriver when the expansion bolt 13 is screwed into a female screw portion 113 formed on the inner periphery of the fixing pin 11. As long as the shape is suitable for various fasteners, the shape is not limited to the illustrated shape.
次に、本発明の交換用トップリフト１を、靴のヒール本体２に装着する手順について説明する。まず、靴のヒール本体２の底部に固定されている摩耗または損傷したトップリフトをヒール本体２から引き離す。その後、ヒール本体２の底面から所定深さの縦孔２１を穿設し、図３（ａ）に示すように、縦孔２１にリフト本体１２から突出した固定ピン１１を挿入する。この際に縦孔２１の孔径は、固定ピン１１の外径とほぼ同径、もしくは固定ピン１１の外径より大径でも良く、孔径の精度を気にかけることなく穿設することができる。拡張ボルト１３を、挿入した固定ピン１１の基端（リフト本体１２の底面側）から、雌ネジ部１１３に螺合させて締結具（図示せず）で締付け、ヒール本体２にトップリフト１を装着する。
Next, the procedure for mounting the replacement top lift 1 of the present invention on the heel body 2 of the shoe will be described. First, the worn or damaged top lift fixed to the bottom of the heel body 2 of the shoe is pulled away from the heel body 2. Thereafter, a vertical hole 21 having a predetermined depth is formed from the bottom surface of the heel main body 2, and the fixing pin 11 protruding from the lift main body 12 is inserted into the vertical hole 21 as shown in FIG. At this time, the hole diameter of the vertical hole 21 may be substantially the same as the outer diameter of the fixing pin 11 or larger than the outer diameter of the fixing pin 11, and can be drilled without worrying about the accuracy of the hole diameter. The extension bolt 13 is screwed into the female screw portion 113 from the base end of the inserted fixing pin 11 (the bottom surface side of the lift main body 12) and tightened with a fastener (not shown), and the top lift 1 is attached to the heel main body 2. Installing.
上述したように、拡張ボルト１３の雄ネジ外径Ｄ３は、Ｄ２≦Ｄ３＜Ｄ１とされているため、拡張ボルト１３を締付けて拡張ボルト１３の先端を拡開部１１２の位置まで螺送（前進）させることで、図３（ｂ）に示すように、スリット１１１が設けられた拡開部１１２が図３（ｂ）中矢印で示す方向へ拡開（拡径）して縦孔２１の内周に喰い込む。すなわち、固定ピン１１の先端がヒール本体２にしっかりと喰い込んでクサビ作用により固定され、ヒール本体２にトップリフト１をしっかりと装着することができる。この際、特殊な工具は不必要で、家庭内で容易にトップリフトの交換作業を行うことができる。
As described above, since the external thread diameter D3 of the expansion bolt 13 is D2 ≦ D3 <D1, the expansion bolt 13 is tightened and the tip of the expansion bolt 13 is screwed to the position of the expanded portion 112 (advanced). 3), as shown in FIG. 3B, the expanded portion 112 provided with the slit 111 expands (expands) in the direction indicated by the arrow in FIG. Eat in the laps. In other words, the tip of the fixing pin 11 can be securely bitten into the heel body 2 and fixed by the wedge action, and the top lift 1 can be securely attached to the heel body 2. At this time, a special tool is unnecessary, and the top lift can be easily replaced at home.
また、トップリフト１が摩耗または損傷した場合は、拡張ボルト１３を緩め、ヒール本体２へ固定された拡開部１１２のクサビ作用を解除することで、容易に固定ピン１１を引き抜いてトップリフト１をヒール本体２から外すことができる。したがって、拡張ボルト１３を螺送するだけで、トップリフト１をヒール本体２に固定する、もしくは固定を解除することが可能となり、トップリフト１の装着が容易に行える。
When the top lift 1 is worn or damaged, the expansion bolt 13 is loosened to release the wedge action of the expanded portion 112 fixed to the heel body 2, so that the fixing pin 11 can be easily pulled out and the top lift 1. Can be removed from the heel body 2. Therefore, it is possible to fix the top lift 1 to the heel body 2 or to release the fixing only by screwing the expansion bolt 13, and the top lift 1 can be easily attached.
次に、本発明の交換用トップリフトの第二の実施形態について、図４、図５を参照して説明する。尚、第一の実施形態と同一の箇所には同一の符号を付し、以下では第一の実施の形態との相違点を主に説明する。
Next, a second embodiment of the replacement top lift according to the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the location same as 1st embodiment, and the difference with 1st embodiment is mainly demonstrated below.
本発明におけるトップリフト１の第二の実施形態は、図４に示すように、拡開部１１２の内周が先端に向かって縮径するテーパー形状に形成されている。そのため、図５（ａ）に示すように、ヒール本体２にトップリフト１を装着した状態から、図５（ｂ）に示すように、さらに拡張ボルト１３を先端方向に螺送させるほど、拡開部１１２が拡開（拡径）して縦孔２１の内周に喰い込み、トップリフト１がヒール本体２により強固に固定される。このように、拡張ボルト１３の位置により縦孔２１への拡開部１２の喰い込みを調節できるため、縦孔２１の内周径が固定ピン１１の外径よりも大径、すなわち縦孔２１の内周面と固定ピン１１の外周面間に間隙があろうとも、トップリフト１をヒール本体２に装着することができる。
In the second embodiment of the top lift 1 according to the present invention, as shown in FIG. 4, the inner periphery of the expanded portion 112 is formed in a tapered shape whose diameter decreases toward the tip. Therefore, as shown in FIG. 5A, from the state in which the top lift 1 is mounted on the heel body 2, as shown in FIG. The portion 112 expands (expands) and bites into the inner periphery of the vertical hole 21, and the top lift 1 is firmly fixed by the heel body 2. Thus, since the biting of the expanded portion 12 into the vertical hole 21 can be adjusted by the position of the expansion bolt 13, the inner peripheral diameter of the vertical hole 21 is larger than the outer diameter of the fixing pin 11, that is, the vertical hole 21. The top lift 1 can be mounted on the heel body 2 even if there is a gap between the inner peripheral surface of the fixing pin 11 and the outer peripheral surface of the fixing pin 11.
一般的に、ヒール本体２は軟質部材から形成されていることが多く、トップリフト１は、一度装着すると、縦孔２１の内周面がヒール本体に挿入される棒状体の形状に変形し易い。そのため、外形が変化することのない従来のトップリフトは、幾度となく交換するたびに、次第に密着力が低下していた。本発明におけるトップリフト１の第二の実施形態においては、拡開部１１２の位置により外形が変化するため、トップリフト１を幾度となく交換しても密着力が低下することなく使用でき、ひいては靴の長寿命化が図れる。
In general, the heel body 2 is often formed of a soft member, and once the top lift 1 is mounted, the inner peripheral surface of the vertical hole 21 is easily deformed into the shape of a rod-like body inserted into the heel body. . For this reason, the conventional top lift, whose outer shape does not change, gradually decreases in adhesion with each replacement. In the second embodiment of the top lift 1 according to the present invention, since the outer shape changes depending on the position of the expanding portion 112, the top lift 1 can be used without lowering the adhesive force even if the top lift 1 is replaced many times. Prolongs the life of shoes.
次に、本発明の交換用トップリフトの第三の実施形態について、図６、図７を参照して説明する。尚、第一の実施形態と同一の箇所には同一の符号を付し、以下では第一の実施の形態との相違点を主に説明する。
Next, a third embodiment of the replacement top lift according to the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the location same as 1st embodiment, and the difference with 1st embodiment is mainly demonstrated below.
本発明におけるトップリフト１の第三の実施形態は、リフト本体１２がヒール本体２に対して回転することを防止する目的で、リフト本体１２の上面にヒール本体と嵌合される突片１２１が設けられている。そのため、突片１２１は、図６に示すような円柱形状や、図７に示すような円錐形状などのほか、三角錐や四角錐、Ｌ字状やＵ字状など、リフト本体１２の上面から突出し、リフト本体１２の回転を規制できれば、何れの形状でも良い。また、突片の数も１つ以上設けられていれば良い。
In the third embodiment of the top lift 1 according to the present invention, for the purpose of preventing the lift main body 12 from rotating with respect to the heel main body 2, a projecting piece 121 fitted to the heel main body is provided on the upper surface of the lift main body 12. Is provided. Therefore, the protrusion 121 has a cylindrical shape as shown in FIG. 6, a conical shape as shown in FIG. 7, a triangular pyramid, a quadrangular pyramid, an L shape or a U shape, and the like from the upper surface of the lift body 12. Any shape may be used as long as it protrudes and the rotation of the lift body 12 can be regulated. Moreover, the number of protrusions should just be provided 1 or more.
以上のように構成されたトップリフト１は、各種靴のヒール本体の底部に縦孔を設けるだけで、容易に装着することができる。尚、本発明の各実施形態において、スリット１１１は、２本のスリット１１１を設けて拡開部１１２を形成しているが、例えば３本のスリット１１１を設けて拡開部１１２を形成しても良く、これに限定されるものではない。
The top lift 1 configured as described above can be easily mounted only by providing a vertical hole at the bottom of the heel body of various shoes. In each embodiment of the present invention, the slit 111 is provided with two slits 111 to form the expanded portion 112. For example, the slit 111 is provided with three slits 111 to form the expanded portion 112. However, the present invention is not limited to this.
本発明によれば、ヒール本体にトップリフトを装着する際に、ヒール本体の底面に精度よく孔加工を施す必要がないため、トップリフトの交換作業が容易に行うことができる。また、本発明の第二の実施形態に示すように、拡開部１１２の内周が先端に向かって縮径するテーパー形状に形成することで、拡張ボルト１３の位置により縦孔２１への拡開部１２の喰い込みを強化できるとともに、トップリフトを幾度となく交換しても密着力の低下を防止することができる。
According to the present invention, when the top lift is mounted on the heel body, it is not necessary to accurately drill holes in the bottom surface of the heel body, so that the top lift can be easily replaced. Further, as shown in the second embodiment of the present invention, the inner periphery of the expanding portion 112 is formed in a tapered shape with a diameter decreasing toward the tip, so that the expansion bolt 13 expands into the vertical hole 21 depending on the position of the expansion bolt 13. The biting of the opening 12 can be strengthened, and a decrease in the adhesion can be prevented even if the top lift is replaced many times.
