Description

本発明は、平面視円形状の点字鋲や、平面視長円形状の誘導バーなどの誘導鋲に関し、特に、床上に敷設する敷設物に配設する誘導鋲に関するものである。 The present invention relates to a guide rod such as a braille rod having a circular shape in plan view or a guide bar having an elliptical shape in plan view, and more particularly to a guide rod disposed on a laying object laid on a floor.

この種の誘導鋲は、視覚障害者の歩行時の誘導に用いられたりするものである。この誘導鋲は、近年では、車道や路面などの硬質な床面だけでなく、建築物内に敷設する絨毯やカーペットなどの軟質な敷設物にも配設される。この敷設物に配設する誘導鋲は、鋲本体と受部材とを備え、鋲本体を歩行者が踏む表面側に配設し、受部材を敷設面である建築物の床に対向する裏面側に配設する。そして、これら鋲本体と受部材とで敷設物を挟み込むようにして配設する構成としている。 This type of guide rod is used for guiding a visually handicapped person when walking. In recent years, this guide rod is disposed not only on a hard floor surface such as a roadway or a road surface, but also on a soft laying object such as a carpet or a carpet laid in a building. The guide rod to be disposed on the laying structure includes a heel body and a receiving member, the heel body is disposed on a surface side on which a pedestrian steps, and the receiving member is disposed on the back surface side facing the floor of the building. It arranges in. And it is set as the structure arrange | positioned so that a laying object may be inserted | pinched by these ridge body and receiving members.

特許文献１には、鋲本体の軸部を中空軸により構成し、この軸部を敷設物に貫通させるとともに、受部材としてワッシャを配設する構成とした誘導鋲が記載されている。そして、この誘導鋲は、軸部の先端内部に治具としてパンチを挿入配置し、裏面側から軸方向に沿って外力を加えることにより軸部を拡開させて係着する構成としている。 Patent Document 1 describes a guide rod having a configuration in which a shaft portion of a rod main body is configured by a hollow shaft, the shaft portion is passed through a laying object, and a washer is disposed as a receiving member. The guide rod is configured such that a punch is inserted and disposed inside the tip of the shaft portion, and the shaft portion is expanded and engaged by applying an external force along the axial direction from the back surface side.

しかし、この特許文献１では、鋲本体を敷設物の表面側と裏面側の両方から支持した状態で、表面側または裏面側から更に打撃により外力を加える必要があるため、装着作業性が悪い。特に、敷設物の面積が大きい場合、その中央部分に誘導鋲を装着する作業は極めて困難である。 However, in this patent document 1, since it is necessary to apply external force further from the surface side or the back surface side in the state which supported the main body from both the surface side and back surface side of a laying thing, mounting workability | operativity is bad. In particular, when the area of the laying object is large, it is extremely difficult to attach the guide rod to the central portion.

特許文献２には、鋲本体を平板状をなすように形成する一方、受部材を薄板リング状の頭部を有する軸により構成した誘導鋲が記載されている。そして、この誘導鋲は、敷設物の表面に鋲本体を配設するとともに、裏面から軸を貫通させて配設し、軸先端の皿状受け部を鋲本体の上面側で塑性変形させることにより係着する構成としている。または、軸の先端にネジ部を設け、裏面側から締め付けることにより係着する構成としている。 Patent Document 2 describes a guide rod in which a rod main body is formed to have a flat plate shape, and a receiving member is constituted by a shaft having a thin plate ring-shaped head. And this guide rod is arranged by arranging the rod main body on the surface of the laying object, penetrating the shaft from the back surface, and plastically deforming the dish-shaped receiving portion at the tip of the shaft on the upper surface side of the rod main body. The structure is engaged. Or it is set as the structure engaged by providing a screw part in the front-end | tip of an axis | shaft, and tightening from a back surface side.

しかし、この特許文献２では、パンチなどの治具を用いて皿状受け部を表面側から塑性変形させる構成であるため、その係着部分を別体のシール部材によって覆い隠す必要がある。そして、このシール部材は、歩行者が踏み付けることによる摩擦および衝撃で、剥がれてしまうという難点がある。但し、ネジ構造による係着では、シール部材は不要であるため、このような問題が生じることはないが、鋲本体および軸部材の一方を支持し、他方を回転させて締め付ける必要があるため、やはり装着作業性が悪い。 However, in this patent document 2, since it is the structure which plastically deforms a plate-shaped receiving part from the surface side using jigs, such as a punch, it is necessary to cover the engaging part with a separate sealing member. And this sealing member has the difficulty that it will peel off by the friction and impact by a pedestrian stepping on. However, since the sealing member is unnecessary in the engagement with the screw structure, such a problem does not occur, but it is necessary to support one of the heel body and the shaft member and rotate and tighten the other, The mounting workability is still bad.

特許文献３では、鋲本体の軸部に環状の係合溝部を設けるとともに、受部材の挿通部に係合溝部に係合する係合爪部を設けた誘導鋲が記載されている。そして、この誘導鋲は、敷設物の裏面に受部材を配設した状態で、表面側から鋲本体を配設し、軸部を挿通部に圧入することにより係合爪部を係合溝部に係合させて係着する構成としている。 Patent Document 3 describes a guide rod in which an annular engagement groove portion is provided in the shaft portion of the rod main body, and an engagement claw portion that engages with the engagement groove portion is provided in the insertion portion of the receiving member. And this guide rod has the receiving member disposed on the back surface of the laying object, the rod body is disposed from the front surface side, and the shaft portion is press-fitted into the insertion portion, whereby the engagement claw portion becomes the engagement groove portion. It is set as the structure engaged and engaged.

しかし、この特許文献３では、係合溝部と係合爪部との係合だけで係着状態が維持されるため、歩行者が鋲本体の突出した平板部を蹴るなどして横向きの負荷を加えると、受部材から鋲本体が離脱する可能性がある。なお、この構成では、軸部と挿通部との間を接着剤で接着する場合もあるが、このようにしても経年的に離脱する可能性がある。 However, in Patent Document 3, since the engaged state is maintained only by the engagement between the engagement groove portion and the engagement claw portion, the pedestrian kicks the protruding flat plate portion of the heel body and applies a lateral load. If added, there is a possibility that the bag main body may be detached from the receiving member. In this configuration, the shaft portion and the insertion portion may be bonded with an adhesive, but even in this case, there is a possibility that they may be separated over time.

本発明は、敷設物への装着作業が良好で、その装着状態を確実に維持できる誘導鋲を提供することを課題とするものである。 It is an object of the present invention to provide a guide rod that can be mounted on a laying object and can reliably maintain the mounting state.

前記課題を解決するため、本発明の第１の誘導鋲は、床上に敷設する敷設物の表面に鋲本体を配設するとともに、前記敷設物の裏面に挿通部を有する受部材を配設し、前記鋲本体の金属製の軸部を前記受部材の挿通部に挿入して係着することにより前記敷設物に配設する誘導鋲であって、前記鋲本体の軸部先端に軸方向に延びる空隙部を設け、この空隙部の外周部を径方向外向きに塑性変形可能な塑性変形部とし、前記受部材の挿通部に、前記鋲本体の塑性変形部が侵入可能な係着段部を、径方向外向きに拡径して設け、前記敷設物を床上に敷設した状態で、前記鋲本体に対して軸方向に外力を加えることにより、前記敷設物の裏面側で前記塑性変形部を塑性変形させ、前記鋲本体と受部材を係着する構成としている。 In order to solve the above-mentioned problem, the first guide rod of the present invention has a rod body disposed on the surface of a laying object laid on the floor and a receiving member having an insertion portion on the back surface of the laying object. A guide rod disposed on the laying object by inserting and engaging the metal shaft portion of the rod main body into the insertion portion of the receiving member, wherein the guide rod is disposed axially at the tip of the shaft portion of the rod body. An engaging step portion provided with an extending gap portion, the outer peripheral portion of the gap portion being a plastically deformable portion that can be plastically deformed radially outwardly, and the plastic deformable portion of the heel body entering the insertion portion of the receiving member In the state where the laying object is laid on the floor, and by applying an external force in the axial direction to the main body, the plastic deformation portion is formed on the back surface side of the laying object. Is plastically deformed, and the hook body and the receiving member are engaged.

また、本発明の第２の誘導鋲は、前記鋲本体の軸部先端に軸方向に延びる空隙部を設け、この空隙部の外周部を径方向外向きに塑性変形可能な塑性変形部とし、前記受部材の挿通部の敷設面側に、前記軸部より硬質な衝突部材を配設し、前記敷設物を床上に敷設した状態で、前記鋲本体に対して軸方向に外力を加えることにより、前記敷設物の裏面側で前記塑性変形部を塑性変形させ、前記鋲本体と受部材を係着する構成としている。Further, the second induction rod of the present invention is provided with a gap portion extending in the axial direction at the tip of the shaft portion of the rod body, and the outer peripheral portion of the gap portion is a plastic deformation portion capable of plastic deformation radially outwardly, By disposing a collision member harder than the shaft portion on the laying surface side of the insertion portion of the receiving member, and applying an external force in the axial direction to the heel body in a state where the laying object is laid on the floor The plastic deformation portion is plastically deformed on the back side of the laying object, and the heel body and the receiving member are engaged.
この第２の誘導鋲では、第１の誘導鋲と同様に、前記受部材の挿通部に、前記鋲本体の塑性変形部が侵入可能な係着段部を、径方向外向きに拡径して設けることが好ましい。 In the second guide rod, similarly to the first guide rod, an engaging step portion into which the plastic deformation portion of the rod main body can enter is inserted radially outwardly into the insertion portion of the receiving member. It is preferable to provide them.

本発明の第１および第２の誘導鋲によれば、敷設物の表面側より鋲本体に対して軸方向に沿って外力を加えることにより、軸部の先端の塑性変形部を敷設物の裏面側で塑性変形させて受部材と係着するため、装着作業時に敷設物の裏面側で受部材を支持する必要はない。そのため、敷設物の面積が大きいものであっても装着作業が阻害されることなく、容易かつ確実に行うことができる。また、鋲本体には、脱落するような別体のシール部材は無いうえ、塑性変形部により鋲本体が受部材から離脱しないため、確実に敷設物への装着状態を維持することができる。 According to the first and second induction rods of the present invention, by applying an external force along the axial direction to the rod main body from the surface side of the laying object, the plastic deformation portion at the tip of the shaft portion is placed on the back surface of the laying object. Since it is plastically deformed on the side and engaged with the receiving member, it is not necessary to support the receiving member on the back side of the laying object during the mounting operation. Therefore, even if the area of the laying object is large, the mounting operation is not hindered and can be performed easily and reliably. In addition, since there is no separate seal member that falls off in the heel body, and the heel body does not come off from the receiving member by the plastic deformation portion, it is possible to reliably maintain the mounting state on the laying object.

そして、第１の誘導鋲では、受部材の挿通部に鋲本体の塑性変形部が侵入可能な係着段部を設けているため、塑性変形部を受部材の底から突出させることなく、確実に係着の目的を達成できる。また、塑性変形部による係着段部との係合力と、係着段部の内周面への圧接力とで、確実に係着することができる。In the first guide rod, since the engaging step portion into which the plastic deformation portion of the rod main body can enter is provided in the insertion portion of the receiving member, the plastic deformation portion can be reliably projected without protruding from the bottom of the receiving member. You can achieve the purpose of mooring. Further, the engagement with the engaging stepped portion by the plastic deformation portion and the pressure contact force to the inner peripheral surface of the engaging stepped portion can be reliably engaged.
また、第２の誘導鋲では、受部材の挿通部の敷設面側に硬質な衝突部材を配設しているため、タイルのように負荷の集中により破損し易い敷設面でも、確実に軸部を塑性変形させて係着することができる。 Further, in the second guide rod, since the hard collision member is disposed on the laying surface side of the insertion portion of the receiving member, the shaft portion is surely secured even on the laying surface that is easily damaged due to load concentration like a tile. Can be plastically deformed and attached.

これらの誘導鋲では、前記空隙部は、前記軸部の先端に向けて開口面積が広がる形状であることが好ましい。このようにすれば、塑性変形部を確実に径方向外向きに変形させることができる。 In these induction rods, it is preferable that the gap portion has a shape in which an opening area is widened toward a tip end of the shaft portion. In this way, the plastic deformation portion can be reliably deformed radially outward.

また、前記鋲本体の軸部および前記受部材の挿通部のうち、一方に係合溝部を設けるとともに、他方に前記係合溝部に係合する係合爪部を設けることが好ましい。このようにすれば、更に係合溝部と係合爪部との係合力が加わるため、確実に離脱を防止できる。 Further , it is preferable that an engagement groove portion is provided on one of the shaft portion of the rod main body and the insertion portion of the receiving member, and an engagement claw portion that engages with the engagement groove portion is provided on the other side. In this way, since the engagement force between the engagement groove and the engagement claw is further applied, it is possible to reliably prevent detachment.

さらに、前記鋲本体は、前記軸部が板状の誘導板部とは別体に形成され、前記誘導板部に軸方向に貫通する装着部を設けるとともに、前記軸部に前記装着部に嵌合する頭部を形成し、前記塑性変形部の塑性変形により、前記軸部の頭部上面と前記誘導板部の装着部上端とが略面一になるとともに、前記誘導板部を脱落不可能に係着するように構成している。このようにすれば、塑性変形部を塑性変形させた正規係着状態を目視により確認できる。よって、係着不良の発生を防止できる。 Further , the shaft body has the shaft portion formed separately from the plate-shaped guide plate portion, provided with a mounting portion penetrating in the axial direction in the guide plate portion, and fitted into the mounting portion on the shaft portion. A head portion is formed, and due to plastic deformation of the plastic deformation portion, the top surface of the head portion of the shaft portion is substantially flush with the upper end of the mounting portion of the guide plate portion, and the guide plate portion cannot be dropped off. It is configured to be engaged with. If it does in this way, the regular engagement state which plastically deformed the plastic deformation part can be checked visually. Therefore, the occurrence of poor engagement can be prevented.

本発明の誘導鋲では、敷設物の表面側より鋲本体に外力を加えることにより、軸部の先端を塑性変形させて受部材と係着するため、装着作業時に敷設物の裏面側で受部材を支持する必要はない。そのため、装着作業性を向上できる。また、塑性変形部の係着により、確実に敷設物への装着状態を維持できる。 In the induction rod according to the present invention, the external force is applied to the rod main body from the surface side of the laying object, so that the tip of the shaft portion is plastically deformed and engaged with the receiving member. There is no need to support. Therefore, mounting workability can be improved. Moreover, the attachment state to a laying thing can be reliably maintained by engagement of a plastic deformation part.

以下、本発明の実施の形態を図面に従って説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１から図４は、本発明に係る実施形態の前提となる参考例の誘導鋲の１つである点字鋲１０を示す。この点字鋲１０は、図１に示すように、打設したコンクリートや敷設したタイルなどからなる床１に、絨毯やカーペットなどの軟質な敷設物２を敷設する建築物において、敷設物２に装着するものである。この点字鋲１０は、鋲本体１１と受部材２０とからなり、敷設物２を表裏面から挟み込むように配設するもので、鋲本体１１には従来例のような別体のシール部材は設けられていない。 FIG. 1 to FIG. 4 show a Braille scissor 10 that is one of reference guide scissors that is a premise of an embodiment according to the present invention. As shown in FIG. 1, the braille pad 10 is attached to the laying object 2 in a building in which a soft laying object 2 such as a carpet or a carpet is laid on the floor 1 made of cast concrete or laying tile. To do. The Braille ridge 10 includes a ridge body 11 and a receiving member 20, and is arranged so as to sandwich the laying object 2 from the front and back surfaces. The heel body 11 is provided with a separate sealing member as in the conventional example. It is not done.

鋲本体１１は、敷設物２の表面側から配設するもので、図２および図３に示すように、板状をなす誘導板部１２と、この誘導板部１２とは別体の軸部１４とを有し、これらがインサート成型により一体的に形成される。 The eaves body 11 is disposed from the surface side of the laying object 2, and as shown in FIGS. 2 and 3, the plate-shaped guide plate portion 12 and the shaft portion separate from the guide plate portion 12 14 and these are integrally formed by insert molding.

誘導板部１２は樹脂製またはゴム製であり、装着状態で敷設物２より上方に突出する板状（円錐台形状）のものである。この誘導板部１２には、歩行者が踏み付けた際の滑り止めを図るために、上面部１３に滑止加工が施されている。この参考例の上面部１３は、複数の四角錐状突出部を平面視で格子状をなすように突設した構成である。なお、この誘導板部１２の下面には、受部材２０に対する回転を防止するために、敷設物２との間に摩擦を生じさせるような突起を設けてもよい。 The guide plate portion 12 is made of resin or rubber and has a plate shape (conical truncated cone shape) that protrudes upward from the laying object 2 in a mounted state. In order to prevent slipping when the pedestrian steps on the guide plate portion 12, the top surface portion 13 is subjected to antislip processing. The upper surface portion 13 of this reference example has a configuration in which a plurality of quadrangular pyramidal protrusions are provided so as to form a lattice shape in plan view. In addition, in order to prevent rotation with respect to the receiving member 20, a projection that causes friction with the laying object 2 may be provided on the lower surface of the guide plate portion 12.

軸部１４は金属製であり、その一端には、誘導板部１２内に埋設される逆円錐台形状の頭部１５を備えている。この軸部１４には、頭部１５と逆側に位置する先端から所定間隔をもった位置に、円環状をなすように切削した係合溝部１６が設けられている。また、軸部１４の先端外周部は、係合溝部１６に係合する受部材２０の係合爪部２４の内側を通過させるために、先細となる傾斜部１７とされている。さらに、軸部１４の先端には、軸方向に沿って頭部１５へ向けて延びる空隙部１８が設けられている。この空隙部１８は、先端に向けて開口面積が広がる形状をなす。この参考例の空隙部１８は、球面状をなすように座ぐりすることにより形成されているが、円錐形状をなすように形成してもよい。この空隙部１８の外周部は塑性変形部１９を構成する。この塑性変形部１９は、空隙部１８の形状および傾斜部１７により先端に向けて肉厚が徐々に小さくなっており、その内面の傾斜により、軸方向に沿った外力が加わると径方向外向きに変形するように作用する。この参考例では、塑性変形部１９の変形効率を考慮して、軸部１４をアルミニウムまたは真鍮により形成している。 The shaft portion 14 is made of metal, and has an inverted frustoconical head portion 15 embedded in the guide plate portion 12 at one end thereof. The shaft portion 14 is provided with an engagement groove portion 16 that is cut so as to form an annular shape at a position having a predetermined interval from the tip located on the opposite side to the head portion 15. Further, the outer peripheral portion of the tip end of the shaft portion 14 is an inclined portion 17 that is tapered in order to pass the inside of the engaging claw portion 24 of the receiving member 20 that engages with the engaging groove portion 16. Further, a gap 18 extending toward the head 15 along the axial direction is provided at the tip of the shaft 14. The gap 18 has a shape in which the opening area is widened toward the tip. The gap portion 18 of this reference example is formed by spotting so as to form a spherical shape, but may be formed so as to have a conical shape. The outer peripheral portion of the gap portion 18 constitutes a plastic deformation portion 19. The plastic deformation portion 19 gradually decreases in thickness toward the tip due to the shape of the gap portion 18 and the inclined portion 17, and when an external force is applied along the axial direction due to the inclination of the inner surface, the plastic deformation portion 19 faces outward in the radial direction. It acts to deform. In this reference example , the shaft portion 14 is made of aluminum or brass in consideration of the deformation efficiency of the plastic deformation portion 19.

受部材２０は樹脂製であり、敷設物２の裏面側に配設されるものである。この受部材２０は、敷設物２に形成される装着孔３より大径の円板状をなす基部２１を備えている。この基部２１の中心には、装着孔３と略同一外径となるように突出部２２が設けられている。この突出部２２の突出寸法は、敷設物２の肉厚より小さい。また、この受部材２０には、突出部２２の先端から基部２１にかけて貫通する孔からなる挿通部２３が設けられている。この挿通部２３は、軸部１４の外径より僅かに小さい内径で形成され、所定の圧力（外力）を加えることにより挿入可能となっている。また、挿通部２３の内面には、軸部１４の係合溝部１６に係合する係合爪部２４が、内向きに突出するように設けられている。この係合爪部２４は、上端から下端に向けて内向きに傾斜する傾斜面を有する。この係合爪部２４の下端から基部２１の下端面までの寸法は、軸部１４の係合溝部１６の下端から先端までの寸法より小さくなるように形成されている。この寸法差は、挿通部２３と軸部１４との間に形成される空隙の容積と塑性変形部１９の容積とで設定される。 The receiving member 20 is made of resin and is disposed on the back side of the laying object 2. The receiving member 20 includes a base portion 21 having a disk shape larger in diameter than the mounting hole 3 formed in the laying object 2. At the center of the base portion 21, a protruding portion 22 is provided so as to have substantially the same outer diameter as the mounting hole 3. The projecting dimension of the projecting portion 22 is smaller than the thickness of the laid object 2. Further, the receiving member 20 is provided with an insertion portion 23 formed of a hole penetrating from the distal end of the protruding portion 22 to the base portion 21. The insertion portion 23 is formed with an inner diameter slightly smaller than the outer diameter of the shaft portion 14, and can be inserted by applying a predetermined pressure (external force). An engaging claw portion 24 that engages with the engaging groove portion 16 of the shaft portion 14 is provided on the inner surface of the insertion portion 23 so as to protrude inward. The engaging claw portion 24 has an inclined surface inclined inward from the upper end toward the lower end. The dimension from the lower end of the engaging claw part 24 to the lower end surface of the base part 21 is formed to be smaller than the dimension from the lower end to the tip of the engaging groove part 16 of the shaft part 14. This dimensional difference is set by the volume of the gap formed between the insertion part 23 and the shaft part 14 and the volume of the plastic deformation part 19.

この点字鋲１０を敷設物２に装着する場合には、まず、敷設物２に対して所定の装着位置に装着孔３を設けておく。そして、図４に示すように、敷設物２の裏面側に受部材２０を配置し、突出部２２を装着孔３に挿入する。ついで、敷設物２を床１に敷設した状態で、表面側に鋲本体１１を配置し、軸部１４を受部材２０の挿通部２３内に圧入する。この圧入は、鋲本体１１の軸部１４の先端が受部材２０の係合爪部２４に当接すると、抵抗の増大により困難になる。 When the braille rod 10 is mounted on the laying object 2, first, the mounting hole 3 is provided at a predetermined mounting position with respect to the laying object 2. Then, as shown in FIG. 4, the receiving member 20 is disposed on the back surface side of the laying object 2, and the protruding portion 22 is inserted into the mounting hole 3. Next, in a state where the laying object 2 is laid on the floor 1, the rod main body 11 is disposed on the surface side, and the shaft portion 14 is press-fitted into the insertion portion 23 of the receiving member 20. This press-fitting becomes difficult due to an increase in resistance when the tip of the shaft portion 14 of the heel body 11 abuts on the engaging claw portion 24 of the receiving member 20.

そのため、例えばこの状態で、鋲本体１１の上面部１３をハンマーなどによって打撃し、軸部１４の軸方向に沿って外力（負荷）を加える。これにより、鋲本体１１の係合溝部１６と受部材２０の係合爪部２４とを係合させるとともに、先端の塑性変形部１９を塑性変形させて、鋲本体１１と受部材２０とを係着する。 Therefore, for example, in this state, the upper surface portion 13 of the bag main body 11 is hit with a hammer or the like, and an external force (load) is applied along the axial direction of the shaft portion 14. As a result, the engagement groove 16 of the heel body 11 and the engagement claw 24 of the receiving member 20 are engaged, and the plastic deformation portion 19 at the tip is plastically deformed to engage the heel body 11 and the receiving member 20. To wear.

具体的には、鋲本体１１を打撃すると、まず、軸部１４の先端の傾斜部１７が受部材２０の係合爪部２４に摺接しながら下向きに移動する。ついで、鋲本体１１の軸部１４の先端が敷設物２の敷設面である床１に激突する。そして、その際の衝撃により塑性変形部１９が径方向外向きに変形しながら、軸部１４が下向きに移動を続ける。その後、鋲本体１１の塑性変形部１９で軸部１４と受部材２０の挿通部２３との空隙を埋め、鋲本体１１の係合溝部１６の下端が受部材２０の係合爪部２４の下端を乗り越えて、これらが係合する。なお、鋲本体１１の軸部１４の先端が床１に激突した際に床１を損傷させる場合、一時的に軸部１４より硬質な素材（例えばステンレス）を床１上に配置することにより、床１の損傷を防止することが好ましい。 Specifically, when the heel body 11 is hit, first, the inclined portion 17 at the tip of the shaft portion 14 moves downward while slidingly contacting the engaging claw portion 24 of the receiving member 20. Next, the tip of the shaft portion 14 of the main body 11 collides with the floor 1 which is the laying surface of the laying object 2. The shaft portion 14 continues to move downward while the plastic deformation portion 19 is deformed radially outward by the impact at that time. After that, the gap between the shaft portion 14 and the insertion portion 23 of the receiving member 20 is filled with the plastic deformation portion 19 of the collar body 11, and the lower end of the engaging groove portion 16 of the collar body 11 is the lower end of the engaging claw portion 24 of the receiving member 20. Get over and engage. In addition, when damaging the floor 1 when the tip of the shaft part 14 of the main body 11 collides with the floor 1, by temporarily placing a material (for example, stainless steel) harder than the shaft part 14 on the floor 1, It is preferable to prevent damage to the floor 1.

このように、本発明の点字鋲１０は、敷設物２の表面側より鋲本体１１に対して軸方向に沿って外力を加えることにより、軸部１４の先端の塑性変形部１９を敷設物２の裏面側で塑性変形させて受部材２０と係着するため、装着作業時に敷設物２の裏面側で受部材２０を支持する必要はない。そのため、敷設物２の面積が大きいものであっても装着作業が阻害されることなく、容易かつ確実に行うことができる。特に、既設の敷設物２に装着している点字鋲１０の一部が破損などによって脱落した場合でも、敷設物２の一部を捲ることにより同様に装着することができる。 As described above, the Braille scissors 10 of the present invention apply the external force along the axial direction to the scissors main body 11 from the surface side of the laying object 2, so that the plastic deformation part 19 at the tip of the shaft part 14 is applied to the laying object 2. Therefore, it is not necessary to support the receiving member 20 on the back side of the laying object 2 during the mounting operation. Therefore, even if the area of the laying object 2 is large, the mounting operation can be easily and reliably performed without being hindered. In particular, even when a part of the Braille ridge 10 attached to the existing laying object 2 falls off due to breakage or the like, it can be similarly attached by rolling a part of the laying object 2.

また、鋲本体１１には、脱落するような別体のシール部材は無い。しかも、鋲本体１１と受部材２０とは、係合溝部１６と係合爪部２４との係合力と、塑性変形部１９の塑性変形による挿通部２３の内周面への圧接力とで、離脱しないように確実に係着することができる。その結果、確実に敷設物２への装着状態を維持することができる。 Further, the bag main body 11 has no separate seal member that falls off. Moreover, the heel body 11 and the receiving member 20 are obtained by the engagement force between the engagement groove portion 16 and the engagement claw portion 24 and the pressure contact force to the inner peripheral surface of the insertion portion 23 due to plastic deformation of the plastic deformation portion 19. It can be securely engaged so as not to leave. As a result, the mounting state on the laying object 2 can be reliably maintained.

さらに、この参考例では、軸部１４に形成する空隙部１８を、先端に向けて開口面積が広がるように設けているため、その外周部の塑性変形部１９を確実に径方向外向きに変形させることができる。即ち、空隙部１８を軸方向に沿った開口面積が均一な円柱形状に形成し、治具を使用しない場合には、打撃方向の僅かなずれで、塑性変形部１９が空隙部１８内に向けて変形する可能性があるが、この参考例では、このような不都合を生じさせることなく、確実に径方向外向きに塑性変形させることができる。 Further, in this reference example , since the gap 18 formed in the shaft portion 14 is provided so that the opening area increases toward the tip, the plastic deformation portion 19 at the outer peripheral portion is reliably deformed radially outward. Can be made. That is, when the gap portion 18 is formed in a cylindrical shape having a uniform opening area along the axial direction and no jig is used, the plastic deformation portion 19 is directed into the gap portion 18 with a slight deviation in the striking direction. However, in this reference example , the plastic deformation can be reliably performed radially outward without causing such inconvenience.

図５および図６は、本発明の第１実施形態の点字鋲１０を示す。この第１実施形態では、受部材２０に参考例と同様に、鋲本体１１の係合溝部１６に係合する係合爪部２４が設けられている。そして、この係合爪部２４における軸部１４の挿通方向先端側の端部に、塑性変形部１９が侵入可能な係着段部２５を更に設けた点で、参考例と大きく相違している。 5 and 6 show the Braille ridge 10 according to the first embodiment of the present invention . In the first embodiment , the receiving member 20 is provided with an engaging claw portion 24 that engages with the engaging groove portion 16 of the collar body 11 as in the reference example . The engagement claw portion 24 is greatly different from the reference example in that an engagement step portion 25 into which the plastic deformation portion 19 can enter is further provided at the end portion on the distal end side of the shaft portion 14 in the engagement claw portion 24. .

この係着段部２５は、受部材２０の挿通部２３の基部２１側の端部を、径方向外向きに拡径して設けられている。即ち、受部材２０の挿通部２３の端部には、挿通部２３の内径より大径の係着段部２５が設けられている。この係着段部２５の外径および軸方向の幅、即ち容積は、装着状態での塑性変形部１９の容積に応じて設定される。 The engaging step portion 25 is provided by expanding the end portion on the base portion 21 side of the insertion portion 23 of the receiving member 20 in a radially outward direction. That is, an engagement step portion 25 having a diameter larger than the inner diameter of the insertion portion 23 is provided at the end of the insertion portion 23 of the receiving member 20. The outer diameter and the axial width, that is, the volume of the engaging step portion 25 are set according to the volume of the plastic deformation portion 19 in the mounted state.

このように構成した第１実施形態の点字鋲１０は、参考例と同様に、敷設物２の裏面側に受部材２０を配設した後、表面側から鋲本体１１の軸部１４を挿入して配置し、鋲部材の上面部１３を打撃して外力を加える。これにより、空隙部１８の外周の塑性変形部１９を径方向外向きに塑性変形させながら、鋲本体１１の係合溝部１６に受部材２０の係合爪部２４を係合させ、これら鋲本体１１と受部材２０を係着する。 In the Braille scissors 10 of the first embodiment configured as described above, the receiving member 20 is disposed on the back surface side of the laying object 2 and the shaft portion 14 of the scissors main body 11 is inserted from the front surface side, as in the reference example. The external force is applied by hitting the upper surface portion 13 of the eaves member. Thus, the engaging claw portions 24 of the receiving member 20 are engaged with the engaging groove portions 16 of the flange main body 11 while the plastic deformation portions 19 on the outer periphery of the gap portion 18 are plastically deformed radially outward. 11 and the receiving member 20 are engaged.

この際、第１実施形態の点字鋲１０は、軸部１４の塑性変形部１９が受部材２０の係着段部２５に入り込むように径方向外向きに塑性変形する。その結果、塑性変形部１９を受部材２０の底から突出させることなく、径方向外向きに塑性変形させて係着段部２５に係着させることができる。そして、この装着状態では、塑性変形部１９と係着段部２５の係合力、塑性変形部１９による係着段部２５の内周面への圧接力、係合溝部１６と係合爪部２４の係合力により、確実に係着することができる。よって、鋲本体１１と受部材２０との離脱を確実に防止できる。 At this time, the Braille rod 10 of the first embodiment is plastically deformed radially outward so that the plastic deformation portion 19 of the shaft portion 14 enters the engaging step portion 25 of the receiving member 20. As a result, the plastic deformation portion 19 can be engaged with the engagement step portion 25 by being plastically deformed radially outward without protruding from the bottom of the receiving member 20. In this mounted state, the engaging force between the plastic deforming portion 19 and the engaging step portion 25, the pressing force against the inner peripheral surface of the engaging step portion 25 by the plastic deforming portion 19, the engaging groove portion 16 and the engaging claw portion 24. Due to the engagement force, it can be securely engaged. Accordingly, it is possible to reliably prevent the heel body 11 and the receiving member 20 from separating.

図７乃至図１０は第２実施形態の点字鋲１０を示す。この第２実施形態では、鋲本体１１を構成する誘導板部１２と軸部１４とを分離した別体により構成した点で、第１実施形態と大きく相違している。なお、第２実施形態の受部材２０は、挿通部２３の端部に係着段部２５を形成した第１実施形態と同様の構成としている。 7 to 10 show a Braille ridge 10 of the second embodiment . The second embodiment is greatly different from the first embodiment in that the guide plate portion 12 and the shaft portion 14 constituting the heel body 11 are configured as separate bodies. In addition, the receiving member 20 of 2nd Embodiment is set as the structure similar to 1st Embodiment which formed the engaging step part 25 in the edge part of the insertion part 23. FIG.

具体的には、図８および図９に示すように、誘導板部１２は、参考例および第１実施形態と同様の円板形状をなす。この誘導板部１２には、上面部１３から下端にかけて軸方向に沿って貫通する装着部２６が設けられている。この装着部２６は、上方に位置する円柱形状の上側装着部２７と、下方に位置する略円錐台形状の下側装着部２８とからなる。軸部１４は、第１実施形態と略同一であり、下側装着部２８に嵌合する逆円錐台形状の頭部１５の上部に、上側装着部２７に嵌合する頭部上層１５ａが設けられている。この頭部上層１５ａの上端面は、参考例および第１実施形態の上面部１３を構成するもので、本実施形態では梨地状をなすように滑止（表面）加工が施されている。この軸部１４は、塑性変形部１９の塑性変形により受部材２０に設計通り装着されると、上面部１３が誘導板部１２の装着部の上端と面一になり、下側装着部２８と頭部１５とで誘導板部１２を脱落不可能に係着する構成としている。 Specifically, as shown in FIGS. 8 and 9, the guide plate portion 12 has a disk shape similar to that of the reference example and the first embodiment . The guide plate portion 12 is provided with a mounting portion 26 penetrating along the axial direction from the upper surface portion 13 to the lower end. The mounting portion 26 includes a columnar upper mounting portion 27 positioned above and a lower mounting portion 28 having a substantially truncated cone shape positioned below. The shaft portion 14 is substantially the same as that of the first embodiment, and a head upper layer 15 a that fits the upper mounting portion 27 is provided on the upper portion of the inverted truncated cone-shaped head 15 that fits the lower mounting portion 28. It has been. The upper end surface of the head upper layer 15a constitutes the upper surface portion 13 of the reference example and the first embodiment , and in this embodiment, anti-slip (surface) processing is performed so as to form a satin finish. When the shaft portion 14 is mounted on the receiving member 20 as designed by plastic deformation of the plastic deformation portion 19, the upper surface portion 13 is flush with the upper end of the mounting portion of the guide plate portion 12, and the lower mounting portion 28 and The guide plate 12 is engaged with the head 15 so that it cannot be removed.

このように構成した第２実施形態の点字鋲１０は、参考例および第１実施形態と同様に、敷設物２の裏面側に受部材２０を配設した後、図１０に示すように、表面側から鋲本体１１の誘導板部１２を配置し、その装着２６部に軸部１４を貫通させて受部材２０の挿通部２３に挿入する。そして、参考例と同様に、軸部１４の先端が受部材２０の係合爪部２４に当接すると、軸部１４の頭部１５を打撃して外力を加え、先端の塑性変形部１９を塑性変形させながら、軸部１４の係合溝部１６と受部材２０の係合爪部２４とを係合させ、軸部１４と受部材２０とを係着する。 As in the reference example and the first embodiment , the Braille ridge 10 of the second embodiment configured as described above has a receiving member 20 disposed on the back surface side of the laying object 2, and then, as shown in FIG. The guide plate portion 12 of the bag main body 11 is arranged from the side, and the shaft portion 14 is passed through the mounting 26 portion and inserted into the insertion portion 23 of the receiving member 20. As in the reference example , when the tip of the shaft portion 14 comes into contact with the engaging claw portion 24 of the receiving member 20, the head 15 of the shaft portion 14 is struck to apply external force, and the plastic deformation portion 19 at the tip is moved. While being plastically deformed, the engaging groove portion 16 of the shaft portion 14 and the engaging claw portion 24 of the receiving member 20 are engaged, and the shaft portion 14 and the receiving member 20 are engaged.

この際、図７に示すように、軸部１４は、その頭部上層１５ａの上面部１３が誘導板部１２の上端と面一になる位置まで外力を加える。これにより、塑性変形部１９の変形状態は、全く目視できない状態であるが、確実に受部材２０の係着段部２５に進入した正規係着状態になったことを確認できる。よって、係着不良の発生を防止できる。 At this time, as shown in FIG. 7, the shaft portion 14 applies an external force to a position where the upper surface portion 13 of the head upper layer 15 a is flush with the upper end of the guide plate portion 12. Thereby, although the deformation state of the plastic deformation part 19 is a state which cannot be visually observed at all, it can be confirmed that the normal engagement state has entered the engagement step portion 25 of the receiving member 20 with certainty. Therefore, the occurrence of poor engagement can be prevented.

図１１および図１２は第３実施形態の点字鋲１０を示す。この第３実施形態では、受部材２０の挿通部２３内の敷設面側に軸部１４より硬質な衝突部材２９を配設した点で、第１実施形態と大きく相違している。この衝突部材２９は、係着段部２５より大径のステンレス鋼板からなる。 FIG. 11 and FIG. 12 show a Braille ridge 10 of the third embodiment . The third embodiment is largely different from the first embodiment in that a collision member 29 that is harder than the shaft portion 14 is disposed on the laying surface side in the insertion portion 23 of the receiving member 20. The collision member 29 is made of a stainless steel plate having a diameter larger than that of the engaging step portion 25.

このように構成した第３実施形態は、打撃により外力を加えると、軸部１４の先端が衝突部材２９に激突することにより、塑性変形部１９が塑性変形する。そして、衝突部材２９は、床１と面接触しているため、軸部１４から衝撃を受けても変形することはないうえ、床１に対する外力の負荷も低減できる。よって、床１がタイルのように負荷が集中すると破損し易いものである場合に、床１を破損させることなく、確実に軸部１４を塑性変形させて受部材２０と係着することができる。 In the third embodiment configured as described above, when an external force is applied by striking, the tip end of the shaft portion 14 collides with the collision member 29, so that the plastic deformation portion 19 is plastically deformed. Since the collision member 29 is in surface contact with the floor 1, it does not deform even when it receives an impact from the shaft portion 14, and the load of external force on the floor 1 can be reduced. Therefore, when the floor 1 is easily damaged when the load is concentrated like a tile, the shaft portion 14 can be reliably plastically engaged with the receiving member 20 without damaging the floor 1. .

図１３および図１４は第４実施形態の点字鋲１０を示す。この第４実施形態では、衝突部材２９を挿通部２３の敷設面側端部から所定間隔をもった位置に設け、その底に樹脂による閉塞部３０を設けた点で、第３実施形態と相違している。このように構成した第４実施形態では、第３実施形態と同様の作用および効果を得ることができるうえ、受部材２０から衝突部材２９が脱落することを確実に防止できる。その結果、取り扱いに関する利便性を向上できる。 FIG. 13 and FIG. 14 show the Braille ridge 10 of the fourth embodiment . In the fourth embodiment, provided with a collision member 29 at a position having a predetermined distance from the laying surface side end portion of the insertion portion 23, a point having a closing portion 30 by the resin at the bottom, it differs from the third embodiment is doing. In the fourth embodiment configured as described above, the same operations and effects as those of the third embodiment can be obtained, and the collision member 29 can be reliably prevented from falling off from the receiving member 20. As a result, the convenience regarding handling can be improved.
