The hook type contact avoidance device has a grip portion and a hook portion. The user can support the body with the strap or operate the door handle by hooking the hook portion on the strap as an object or the door handle while the grip portion is gripped by hand.
　接触回避器具の利便性を高めることが求められている。 It is required to improve the convenience of contact avoidance devices.
　上記の要求に応えるために提供されうる本開示に係る一態様は、接触回避器具であって、
　ユーザの指の挿通を許容する開口部を有する把持部と、
　前記把持部との間に対象物の通過を許容する開放部を形成する形状を有しているフック部と、を備えており、
　前記フック部は、前記開放部を通過した前記対象物との接触に供される接触面を有しており、
　前記接触面は、前記開放部に面している第一部分と、当該第一部分と前記開放部の間において前記把持部に面している第二部分とを有しており、
　前記接触面の第二部分は、前記対象物が前記接触面に接触した状態で前記把持部に鉛直下方への荷重が加えられるとき、前記開口部の開口方向から見て前記開口部における最も鉛直下方に位置する点に接しかつ水平方向に延びる第一直線と鋭角に交わる第二直線と平行に延びる部分を有している。 One aspect of the present disclosure that may be provided to meet the above requirements is a contact avoidance device.
A grip with an opening that allows the insertion of a user's finger,
It is provided with a hook portion having a shape forming an open portion that allows passage of an object between the grip portion and the grip portion.
The hook portion has a contact surface that is subjected to contact with the object that has passed through the open portion.
The contact surface has a first portion facing the open portion and a second portion facing the grip portion between the first portion and the open portion.
The second portion of the contact surface is the most vertical in the opening when the object is in contact with the contact surface and a load is applied vertically downward to the grip. It has a portion that extends parallel to the first straight line that touches a point located below and extends horizontally and the second straight line that intersects at an acute angle.
　上記の態様に係る構成によれば、対象物が接触面に接触した状態で把持部に鉛直下方への荷重が加えられるとき、把持部に対向している第二部分は、開放部からより遠方にある第一部分に向かって斜め上方へ直線的に延びる部分を有している。これにより、第一部分と第二部分の間に導かれた対象物へ荷重を効率的に作用させることができる。加えて、荷重と交差する方向へ外力が作用しても対象物が開放部に向かって変位しにくくできるので、対象物が予期せずフック部から離脱する事態の発生を抑制できる。したがって、接触回避器具の利便性を高めることができる。 According to the configuration according to the above aspect, when a load vertically downward is applied to the grip portion while the object is in contact with the contact surface, the second portion facing the grip portion is farther from the open portion. It has a portion that extends linearly diagonally upward toward the first portion in. As a result, the load can be efficiently applied to the object guided between the first portion and the second portion. In addition, even if an external force acts in the direction intersecting the load, the object can be less likely to be displaced toward the open portion, so that the occurrence of a situation in which the object unexpectedly separates from the hook portion can be suppressed. Therefore, the convenience of the contact avoidance device can be enhanced.

　このような構成によれば、対象物１００が接触面１２２に接触した状態で把持部１１に鉛直下方への荷重が加えられるとき、把持部１１に対向している第二部分１２２Ｂは、開放部１２１からより遠方にある第一部分１２２Ａに向かって斜め上方へ直線的に延びる部分１２２Ｂ１を有している。これにより、第一部分１２２Ａと第二部分１２２Ｂの間に導かれた対象物１００へ荷重を効率的に作用させることができる。加えて、荷重と交差する方向へ外力が作用しても対象物１００が開放部１２１に向かって変位しにくくできるので、対象物１００が予期せずフック部１２から離脱する事態の発生を抑制できる。したがって、接触回避器具１０の利便性を高めることができる。 According to such a configuration, when a load vertically downward is applied to the grip portion 11 in a state where the object 100 is in contact with the contact surface 122, the second portion 122B facing the grip portion 11 is an open portion. It has a portion 122B1 that extends linearly diagonally upward toward the first portion 122A, which is farther from 121. As a result, the load can be efficiently applied to the object 100 guided between the first portion 122A and the second portion 122B. In addition, even if an external force acts in the direction intersecting the load, the object 100 can be less likely to be displaced toward the open portion 121, so that the occurrence of a situation in which the object 100 unexpectedly separates from the hook portion 12 can be suppressed. .. Therefore, the convenience of the contact avoidance device 10 can be enhanced.
　接触面１２２の第一部分１２２Ａは、図６に例示されるように、部分１２２Ａ１を含みうる。部分１２２Ａ１は、対象物１００が接触面１２２に接触した状態で把持部１１に鉛直下方への荷重が加えられるとき、開口部１１１の開口方向から見て第二部分１２２Ｂから離れるにつれて開放部１２１から離れるように延びている。このような構成によれば、対象物１００が接触面１２２に接触した状態で把持部１１に鉛直下方への荷重が加えられるとき、開放部１２１からより遠方にある第一部分１２２Ａに向かって斜め上方へ直線的に延びる部分１２２Ｂ１を有するように第二部分１２２Ｂを構成しても、荷重の作用に供される対象物１００が導かれる位置を比較的広く確保できる。換言すると、第一部分１２２Ａと第二部分１２２Ｂの双方を通じて対象物１００に荷重を作用させやすくなるので、接触状態の安定性を高めることができる。 The first portion 122A of the contact surface 122 may include the portion 122A1 as illustrated in FIG. When a load vertically downward is applied to the grip portion 11 in a state where the object 100 is in contact with the contact surface 122, the portion 122A1 is separated from the opening portion 121 as it moves away from the second portion 122B when viewed from the opening direction of the opening portion 111. It extends away. According to such a configuration, when a load vertically downward is applied to the grip portion 11 in a state where the object 100 is in contact with the contact surface 122, it is obliquely upward toward the first portion 122A farther from the open portion 121. Even if the second portion 122B is configured to have the portion 122B1 extending linearly to, the position where the object 100 subjected to the action of the load is guided can be secured relatively widely. In other words, since it becomes easy to apply a load to the object 100 through both the first portion 122A and the second portion 122B, the stability of the contact state can be improved.
　開口部１１１は、図２に例示されるように、ユーザの複数の指Ｆの挿通を許容する大きさを有しうる。このような構成によれば、対象物１００により強い荷重を加えることができるとともに、把持部１１から指Ｆに加わる応力が複数の指Ｆに分散されるので、使用時の快適性を高めることができる。 As illustrated in FIG. 2, the opening 111 may have a size that allows the insertion of a plurality of fingers F of the user. According to such a configuration, a stronger load can be applied to the object 100, and the stress applied to the fingers F from the grip portion 11 is distributed to the plurality of fingers F, so that the comfort during use can be improved. can.
　接触面１２２は、図１に例示されるように、第一部分１２２Ａと第二部分１２２Ｂとの間に形成された湾曲面１２２Ｃを含みうる。このような構成によれば、第一部分１２２Ａと第二部分１２２Ｂとの間に位置する部分において対象物１００との間に生じる摩擦抵抗を軽減できる。これにより、第一部分１２２Ａと第二部分１２２Ｂとの間に図２および図３に例示されるつり革１０１などの対象物１００が導かれるような使用がなされる場合、使用時の快適性を高めることができる。 The contact surface 122 may include a curved surface 122C formed between the first portion 122A and the second portion 122B, as illustrated in FIG. According to such a configuration, the frictional resistance generated between the object 100 and the portion located between the first portion 122A and the second portion 122B can be reduced. As a result, when the object 100 such as the strap 101 illustrated in FIGS. 2 and 3 is guided between the first portion 122A and the second portion 122B, the comfort during use is enhanced. be able to.
　接触面１２２の第二部分１２２Ｂは、図６に例示されるように、把持部１１に向かって伸びる部分１２２Ｂ２を含みうる。このような構成によれば、図３に例示されるように電車やバスの揺れなどによる予期せぬ外力の作用によってつり革１０１などの対象物１００が開放部１２１に近づくのを阻止し、対象物１００がフック部１２から離脱する事態の発生を抑制できる。 The second portion 122B of the contact surface 122 may include a portion 122B2 extending toward the grip portion 11, as illustrated in FIG. According to such a configuration, as illustrated in FIG. 3, the object 100 such as the strap 101 is prevented from approaching the opening portion 121 due to the action of an unexpected external force due to the shaking of a train or a bus, and the object is prevented. It is possible to suppress the occurrence of a situation in which the object 100 is detached from the hook portion 12.
　接触面１２２は、図１に例示されるように、第一部分１２２Ａと把持部１１との間に形成された湾曲面１２２Ｄを含みうる。このような構成によれば、フック部１２と把持部１１との間に位置する部分において対象物１００との間に生じる摩擦抵抗を軽減できる。これにより、フック部１２と把持部１１との間に図４に例示されるドアハンドル１０２などの対象物１００を挟むような使用がなされる場合、使用時の快適性を高めることができる。換言すると対象物１００の保持に把持部１１を関与させる場合において、使用時の快適性を高めることができる。 The contact surface 122 may include a curved surface 122D formed between the first portion 122A and the grip portion 11, as illustrated in FIG. According to such a configuration, the frictional resistance generated between the object 100 and the portion located between the hook portion 12 and the grip portion 11 can be reduced. As a result, when the object 100 such as the door handle 102 illustrated in FIG. 4 is sandwiched between the hook portion 12 and the grip portion 11, the comfort during use can be enhanced. In other words, when the grip portion 11 is involved in holding the object 100, the comfort during use can be enhanced.
　接触回避器具１０は、図７に例示される開口部１１１の開口方向における接触面１２２の第一部分１２２Ａの最小寸法Ｄ１が、図８に例示されるフック部１２の開放部１２１に面していない部分１２４の寸法Ｄ２よりも大きくなるように形成されうる。このような構成によれば、対象物１００に対して接触可能なフック部１２の面積を確保しつつ、接触回避器具１０の大型化と重量増を抑制できる。 In the contact avoidance device 10, the minimum dimension D1 of the first portion 122A of the contact surface 122 in the opening direction of the opening 111 exemplified in FIG. 7 does not face the opening portion 121 of the hook portion 12 exemplified in FIG. It can be formed to be larger than the dimension D2 of the portion 124. According to such a configuration, it is possible to suppress the increase in size and weight of the contact avoidance device 10 while securing the area of the hook portion 12 that can come into contact with the object 100.
　開口部１１１の内壁１１１Ｅおよびその周囲の把持部１１の一部は、図９に例示されるように、接触回避器具１０を開口部１１１の開口方向と交差する面３００に載置したときに、当該面３００から離れるように構成されうる。このような構成は、接触回避器具１０の重心位置や寸法を調整することにより実現されうる。例えば、接触回避器具１０は、開口部１１１の開口方向におけるフック部１２と把持部１１との間に位置する部分の寸法Ｄ３が把持部１１の寸法Ｄ４よりも大きくなるように形成されうる。あるいは、接触回避器具１０は、フック部１２またはフック部１２と把持部１１との間に位置する部分が接触回避器具１０の重心となるように形成されうる。 When the contact avoidance device 10 is placed on the surface 300 intersecting the opening direction of the opening 111, the inner wall 111E of the opening 111 and a part of the grip portion 11 around the inner wall 111E are placed on the surface 300 intersecting the opening direction of the opening 111, as illustrated in FIG. It may be configured to move away from the surface 300. Such a configuration can be realized by adjusting the position and dimensions of the center of gravity of the contact avoidance device 10. For example, the contact avoidance device 10 may be formed so that the dimension D3 of the portion located between the hook portion 12 and the grip portion 11 in the opening direction of the opening portion 111 is larger than the dimension D4 of the grip portion 11. Alternatively, the contact avoidance device 10 may be formed so that the hook portion 12 or the portion located between the hook portion 12 and the grip portion 11 is the center of gravity of the contact avoidance device 10.
　このような構成によれば、接触回避器具１０を机などの面３００の上に置いた場合、机などに付着した可能性があるウィルス等の忌避物が接触回避器具１０におけるユーザの指との接触に供される部分に付着することを抑制できる。 According to such a configuration, when the contact avoidance device 10 is placed on a surface 300 such as a desk, a repellent such as a virus that may have adhered to the desk or the like is placed on the user's finger on the contact avoidance device 10. It is possible to suppress the adhesion to the portion to be contacted.
　接触回避器具１０は、図１０に例示されるように、フック部１２の全体を覆う軟質樹脂１３を備えうる。図１０において、軟質樹脂１３に覆われている部分はハッチングが付されている。軟質樹脂１３の例としては、エラストマーなどの軟質樹脂などが挙げられる。このような構成によれば、外力の作用により予期せずフック部１２が破損した場合においても、破片の飛散を軟質部材１３により抑制できる。 As illustrated in FIG. 10, the contact avoidance device 10 may include a soft resin 13 that covers the entire hook portion 12. In FIG. 10, the portion covered with the soft resin 13 is hatched. Examples of the soft resin 13 include soft resins such as elastomers. According to such a configuration, even if the hook portion 12 is unexpectedly damaged by the action of an external force, the scattering of debris can be suppressed by the soft member 13.
　軟質樹脂１３は、少なくとも接触面１２２を覆うような構成を採用されうる。この場合、接触面１２２に適度の摩擦抵抗を付与できるので、接触面１２２に接触した対象物１００の滑りを抑制できる。 The soft resin 13 may be configured to cover at least the contact surface 122. In this case, since an appropriate frictional resistance can be imparted to the contact surface 122, slippage of the object 100 in contact with the contact surface 122 can be suppressed.
　フック部１２は、図１に例示されるように、把持部１１から離れる方向に延びる凸部１２３を有しうる。このような構成によれば、つり革１０１やドアハンドル１０２などの対象物にフック部１２を掛ける使用態様に加えて、図５に例示されるボタン１０３などの対象物を凸部１２３で操作する使用態様が可能となる。 As illustrated in FIG. 1, the hook portion 12 may have a convex portion 123 extending in a direction away from the grip portion 11. According to such a configuration, in addition to the usage mode in which the hook portion 12 is hung on the object such as the strap 101 or the door handle 102, the object such as the button 103 illustrated in FIG. 5 is operated by the convex portion 123. The usage mode becomes possible.
　凸部１２３の少なくとも一部は、導電性を有しうる。これにより、把持部１１を把持した状態でタッチパネルなどの対象物１００を凸部１２３で操作する使用態様が可能となる。なお、凸部１２３が軟質樹脂１３により覆われている場合は、例えば、軟質樹脂１３として金属又は炭素の微粒子が混合された軟質樹脂が使用されうる。 At least a part of the convex portion 123 may have conductivity. This enables a usage mode in which the object 100 such as a touch panel is operated by the convex portion 123 while the grip portion 11 is gripped. When the convex portion 123 is covered with the soft resin 13, for example, a soft resin in which metal or carbon fine particles are mixed can be used as the soft resin 13.

　上記の実施形態において、図６に例示されるように、対象物１００が接触面１２２に接触した状態で把持部１１に鉛直下方への荷重が加えられるときにユーザの指が載置される開口部１１１の面１１１Ａは、第一直線Ｌ１と平行に延びている。しかしながら、図１１に例示されるように、ユーザの指が載置される開口部１１１の面１１１Ａは、ユーザの指の形状に沿うように湾曲している形状を有してもよい。 In the above embodiment, as illustrated in FIG. 6, an opening in which a user's finger is placed when a vertically downward load is applied to the grip portion 11 in a state where the object 100 is in contact with the contact surface 122. The surface 111A of the portion 111 extends parallel to the first straight line L1. However, as illustrated in FIG. 11, the surface 111A of the opening 111 on which the user's finger is placed may have a shape curved along the shape of the user's finger.
　上記の実施形態において、開口部１１１の内壁１１１Ｅおよびその周囲の把持部１１の一部は、接触回避器具１０を開口部１１１の開口方向と交差する面３００に載置したときに、当該面３００から離れるように構成されている。しかしながら、開口部１１１の内壁１１１Ｅの少なくとも一部が、接触回避器具１０を開口部１１１の開口方向と交差する面３００に載置したときに、当該面３００から離れるような構成も採用されうる。このような構成によっても、接触回避器具１０を机などの面の上に置いた場合、机などに付着した可能性があるウィルス等の忌避物が接触回避器具１０におけるユーザの指との接触に供される部分に付着することを抑制できる。 In the above embodiment, the inner wall 111E of the opening 111 and a part of the grip portion 11 around it are placed on the surface 300 intersecting the opening direction of the opening 111 when the contact avoidance device 10 is placed on the surface 300. It is configured to stay away from. However, a configuration may be adopted in which at least a part of the inner wall 111E of the opening 111 is separated from the surface 300 when the contact avoidance device 10 is placed on the surface 300 intersecting the opening direction of the opening 111. Even with such a configuration, when the contact avoidance device 10 is placed on a surface such as a desk, a repellent such as a virus that may have adhered to the desk or the like is in contact with the user's finger in the contact avoidance device 10. It is possible to suppress the adhesion to the provided portion.
　上記の実施形態において、軟質樹脂１３は、フック部１２に加えて把持部１１の一部も覆うように形成されうる。しかしながら、軟質樹脂１３は、把持部１１の全てを覆うように形成されてもよく、あるいは、フック部１２のみを覆うように形成されてもよい。 In the above embodiment, the soft resin 13 can be formed so as to cover a part of the grip portion 11 in addition to the hook portion 12. However, the soft resin 13 may be formed so as to cover the entire grip portion 11, or may be formed so as to cover only the hook portion 12.
　本開示の一部を構成するものとして、２０２０年９月１４日に提出された日本国特許出願２０２０－１５３９２２号の内容が援用される。 The contents of Japanese Patent Application No. 2020-153922 filed on September 14, 2020 will be incorporated as part of this disclosure.
