Figure ((a) is a normal use state, (b) is a self-supporting state), FIG. 3 is a view of the cane shown in FIG. 2 from the left side ((a) is a normal use state, (b) is 4 is a longitudinal sectional view showing the shaft fixing mechanism of the cane (FIG. 4A is a state in which the second shaft constituent member is slid downward, and FIG. 4B is an upper view of the second shaft constituent member. 5 is a side view showing another example of the shaft fixing mechanism of the cane, and FIG. 6 is a longitudinal sectional view showing the configuration around the leg of the cane ((a) shows the leg. The stowed state (legs closed), (b) is the leg unfolded (legs opened).
図1(a),図2(a),図3(a)に示すように、本実施の形態の杖1は、使用者に把持されるシャフト2と、シャフト2の下端に設けられた石突き3と、を備えている。ここでは、シャフト2の上端に把手4が固定されており、使用者は、当該把手4を手で握ることによってシャフト2を把持することができるようにされている。 As shown in FIGS. 1 (a), 2 (a), and 3 (a), a cane 1 according to this embodiment includes a shaft 2 held by a user and a stone provided at the lower end of the shaft 2. And a protrusion 3. Here, the handle 4 is fixed to the upper end of the shaft 2, and the user can grip the shaft 2 by gripping the handle 4 with his / her hand.
図1〜図6に示すように、シャフト2は、上端に把手4が固定され、下端が開口した中空円筒状の第1シャフト構成部材2aと、第1シャフト構成部材2a上にスライド可能に装着され(図1の矢印A,B、図4の矢印D,E、図6の矢印F,G参照)、下端に石突き3が設けられた両端開口の中空円筒状の第2シャフト構成部材2bと、第2シャフト構成部材2bを第1シャフト構成部材2a上の所定の位置に固定するシャフト固定機構と、を備えている。尚、シャフト固定機構の詳細については後述する(図4参照)。 As shown in FIGS. 1 to 6, the shaft 2 has a handle 4 fixed to the upper end and a hollow cylindrical first shaft component 2a having an open lower end, and is slidably mounted on the first shaft component 2a. 1 (see arrows A and B in FIG. 1, arrows D and E in FIG. 4, arrows F and G in FIG. 6), and a hollow cylindrical second shaft component 2b having both ends opened with a butt 3 at the lower end. And a shaft fixing mechanism that fixes the second shaft constituent member 2b to a predetermined position on the first shaft constituent member 2a. The details of the shaft fixing mechanism will be described later (see FIG. 4).
シャフト2の素材としては、例えば、アルミニウム、鉄、カーボン等の任意の素材を用いることができる。 As a material of the shaft 2, for example, any material such as aluminum, iron, or carbon can be used.
石突き3の素材としては、例えば、弾性変形可能で接面性の良好なエラストマー、プラスチック等の任意の素材を用いることができる。図6に示すように、石突き3は、略円錐台状に形成されており、その中心軸上には第2シャフト構成部材2bの外径と略同径の円筒状の貫通孔3aが形成されている。そして、第2シャフト構成部材2bの下端部を貫通孔3aに嵌め込むことにより、第2シャフト構成部材2bの下端部に石突き3が固定されている。ここで、第2シャフト構成部材2bの下端は石突き3の下端よりも多少上方に位置しており、これにより、杖1の使用時に第2シャフト構成部材2bの下端が直に地面に当たって異音を発することがないようにされている。 As the material of the stone bump 3, for example, an arbitrary material such as an elastomer or plastic that can be elastically deformed and has good surface contact property can be used. As shown in FIG. 6, the stone bump 3 is formed in a substantially truncated cone shape, and a cylindrical through hole 3 a having the same diameter as the outer diameter of the second shaft component 2 b is formed on the central axis thereof. Has been. And the stone thrust 3 is being fixed to the lower end part of the 2nd shaft structural member 2b by fitting the lower end part of the 2nd shaft structural member 2b in the through-hole 3a. Here, the lower end of the second shaft constituent member 2b is located slightly above the lower end of the stone thrusting 3 so that when the cane 1 is used, the lower end of the second shaft constituent member 2b directly hits the ground and makes an abnormal noise. It has been made not to emit.
図1〜図4に示すように、上記したシャフト固定機構は、第2シャフト構成部材2bの上端部の周壁を径方向に貫通し、当該第2シャフト構成部材2bの径方向内方に付勢されたピン6aを有するストッパ手段6と、第1シャフト構成部材2aの外周面に長手方向に沿って形成され、ピン6aの先端部をスライドさせることが可能な溝5と、溝5の底面に穿設され、ピン6aが挿入される複数の係止部の一例である貫通孔5a,5b,・・・と、を備えている。ここで、ピン6aには、第2シャフト構成部材2bの周壁の外側に位置する基端部に摘み6bが一体に形成されており、当該摘み6bを摘まんでピン6aを貫通孔5a,5b,・・・から抜くことができるようにされている(図4の矢印C参照)。 As shown in FIGS. 1 to 4, the shaft fixing mechanism described above penetrates the peripheral wall of the upper end portion of the second shaft constituting member 2b in the radial direction and urges radially inward of the second shaft constituting member 2b. The stopper means 6 having the pin 6a formed, the groove 5 formed along the longitudinal direction on the outer peripheral surface of the first shaft constituting member 2a and capable of sliding the tip of the pin 6a, and the bottom surface of the groove 5 Are provided as through holes 5a, 5b,..., Which are examples of a plurality of locking portions that are drilled and into which the pins 6a are inserted. Here, the pin 6a is integrally formed with a knob 6b at a base end portion located on the outer side of the peripheral wall of the second shaft constituting member 2b, and the pin 6a is pinched to be inserted into the through holes 5a, 5b, ... (See arrow C in FIG. 4).
第2シャフト構成部材2bの上端部の外周面には、幅広の輪ゴム6cが取り付けられており、当該幅広の輪ゴム6cの一部はピン6aの基端部に固着されている(図4参照)。そして、これにより、ピン6aは、上記のように第2シャフト構成部材2bの径方向内方に付勢された状態となっている。
かかる構成によれば、シャフト固定機構におけるピン6aの付勢手段を、簡単な構成によって実現することができる。
A wide rubber band 6c is attached to the outer peripheral surface of the upper end portion of the second shaft constituting member 2b, and a part of the wide rubber band 6c is fixed to the base end portion of the pin 6a (see FIG. 4). . As a result, the pin 6a is urged radially inward of the second shaft constituting member 2b as described above.
According to this configuration, the biasing means for the pin 6a in the shaft fixing mechanism can be realized with a simple configuration.
図4(b)に示すようにストッパ手段6のピン6aが溝5の上端に位置しているとき、当該ピン6aは、幅広の輪ゴム6cによる付勢力によってその先端が溝5の底面に押し付けられる。そして、これにより、第2シャフト構成部材2bが第1シャフト構成部材2a上の第1の所定の位置に固定される。このとき、図6(b)に示すように、第2シャフト構成部材2bの下端面は、第1シャフト構成部材2aの下端面とほぼ面一となる。
図4(b)の状態から第2シャフト構成部材2bを下方にスライドさせると(図4(b)の矢印E参照)、ピン6aの先端部が溝5をスライドして一番上の貫通孔5aに挿入する(図4(a)参照)。そして、これにより、第2シャフト構成部材2bが第1シャフト構成部材2a上の第2の所定の位置に固定される。第2シャフト構成部材2bをさらに下方にスライドさせたい場合には、ストッパ手段6の摘み6bを引っ張り(図4(a)の矢印C参照)、ピン6aの先端を貫通孔5aから抜いて溝5の上に載せればよい。図4(a)の状態から第2シャフト構成部材2bを上方にスライドさせたい場合も、同様である。
4B, when the pin 6a of the stopper means 6 is positioned at the upper end of the groove 5, the tip of the pin 6a is pressed against the bottom surface of the groove 5 by the urging force of the wide rubber band 6c. . And thereby, the 2nd shaft structural member 2b is fixed to the 1st predetermined position on the 1st shaft structural member 2a. At this time, as shown in FIG. 6B, the lower end surface of the second shaft constituting member 2b is substantially flush with the lower end surface of the first shaft constituting member 2a.
When the second shaft component 2b is slid downward from the state shown in FIG. 4B (see arrow E in FIG. 4B), the tip of the pin 6a slides in the groove 5 and the top through hole 5a (see FIG. 4A). And thereby, the 2nd shaft structural member 2b is fixed to the 2nd predetermined position on the 1st shaft structural member 2a. When the second shaft component 2b is to be slid further downward, the knob 6b of the stopper means 6 is pulled (see arrow C in FIG. 4 (a)), and the tip of the pin 6a is removed from the through hole 5a to form the groove 5 Just place it on the top. The same applies when it is desired to slide the second shaft component 2b upward from the state of FIG.
また、杖1は、シャフト固定機構において、図4に示す貫通孔5a,5b,・・・の代わりに、図5に示す係止部の一例である補助溝5a’,5b’,・・・を形成してもよい。補助溝5a’,5b’,・・・は、溝5が延びる方向と直交する方向に延び、溝5と一体的に形成され、ピン6aの先端部を溝5からスライドさせることが可能である。この場合、使用者は、図4(b)の状態から第2シャフト構成部材2bを下方にスライドさせ、例えば、図5に示す補助溝5a’が形成された位置にピン6aが配置されたときに、第2シャフト構成部材2bを第1シャフト構成部材2aを軸心として回動させる。これにより、ピン6aの先端部が補助溝5a’内に入り係止され、第2シャフト構成部材2bが第1シャフト構成部材2aに対し、上下に移動するのを規制できる。 In addition, the cane 1 is an auxiliary groove 5a ′, 5b ′,..., Which is an example of a locking portion shown in FIG. 5, instead of the through holes 5a, 5b,. May be formed. Auxiliary grooves 5a ′, 5b ′,... Extend in a direction orthogonal to the direction in which the groove 5 extends, are formed integrally with the groove 5, and can slide the tip of the pin 6a from the groove 5. . In this case, the user slides the second shaft constituent member 2b downward from the state of FIG. 4B, for example, when the pin 6a is arranged at the position where the auxiliary groove 5a ′ shown in FIG. 5 is formed. Then, the second shaft component 2b is rotated about the first shaft component 2a. Thereby, the front-end | tip part of the pin 6a enters into the auxiliary | assistant groove | channel 5a ', is locked, and it can control that the 2nd shaft structural member 2b moves up and down with respect to the 1st shaft structural member 2a.
図1(b),図2(b),図3(b),図6に示すように、第1シャフト構成部材2aの下端内周縁には、3本の棒状の脚体7a,7b,7cがそれぞれゴム材8a,8b,8cを介して開閉可能に取り付けられている。また、脚体7a,7b,7cの取付部分の下方近傍には、当該脚体7a,7b,7cの内側に(すなわち、当該脚体7a,7b,7cに挟まれた状態で)空気の入ったゴムまり9が配設されており、これにより、脚体7a,7b,7cは、開方向に付勢された状態となっている。また、脚体7a,7b,7cは、球状に膨らんだゴムまり9との接触部分にそれぞれゴム材10a,10b,10cを介して連結されている。 As shown in FIG. 1B, FIG. 2B, FIG. 3B, and FIG. 6, three rod-like legs 7a, 7b, and 7c are formed on the inner periphery of the lower end of the first shaft constituting member 2a. Are attached via rubber materials 8a, 8b, 8c so as to be openable and closable. Further, in the vicinity of the lower part of the attachment portion of the legs 7a, 7b, 7c, air enters inside the legs 7a, 7b, 7c (that is, sandwiched between the legs 7a, 7b, 7c). A rubber ball 9 is provided, and the legs 7a, 7b, 7c are thus urged in the opening direction. Further, the legs 7a, 7b, 7c are connected to contact portions with the rubber ball 9 swelled in a spherical shape via rubber materials 10a, 10b, 10c, respectively.
ゴムまり9は、ストッパ手段6のピン6aが溝5の上端に位置した状態で(図4(b)参照)シャフト2の下端から飛び出して球状に膨らみ、これにより、脚体7a,7b,7cが三角錐状に展開保持された状態となるようにされている(図1(b),図2(b),図3(b),図6(b)参照)。 The rubber ball 9 protrudes from the lower end of the shaft 2 and swells into a spherical shape with the pin 6a of the stopper means 6 positioned at the upper end of the groove 5 (see FIG. 4B). Are expanded and held in a triangular pyramid shape (see FIGS. 1B, 2B, 3B, and 6B).
一方、図1(b),図2(b),図3(b),図6(b)の状態から第2シャフト構成部材2bを下方にスライドさせると(図1(b)の矢印B、図6(b)の矢印G参照)、当該第2シャフト構成部材2bの下端内周部によって脚体7a,7b,7cが閉じられていき、それに伴ってゴムまり9が脚体7a,7b,7cに押されて縦長に変形していく。このとき、ストッパ手段6のピン6aの先端部は、溝5を上端から下方にスライドしていき、一番上の貫通孔5aに挿入されて、第2シャフト構成部材2bが第1シャフト構成部材2a上の第2の所定の位置に固定される。そして、脚体7a,7b,7cは、ゴムまり9と共に第2シャフト構成部材2bの下端部内に収納される(図1(a),図2(a),図3(a),図6(a)参照)。
本実施の形態の杖1の構成によれば、このように脚体7a,7b,7cをゴムまり9と共に第2シャフト構成部材2bの下端部内に収納することができるので、使用時における外観が通常の杖と変わらない自立杖を提供することができる。
On the other hand, when the second shaft constituent member 2b is slid downward from the state of FIGS. 1B, 2B, 3B, and 6B (arrow B in FIG. 1B, 6B), the legs 7a, 7b, 7c are closed by the inner peripheral portion of the lower end of the second shaft constituting member 2b, and accordingly, the rubber ball 9 becomes the legs 7a, 7b, It is pushed by 7c and deforms vertically. At this time, the tip of the pin 6a of the stopper means 6 slides downward from the upper end of the groove 5 and is inserted into the uppermost through hole 5a, so that the second shaft constituent member 2b becomes the first shaft constituent member. It is fixed at a second predetermined position on 2a. The legs 7a, 7b, and 7c are housed in the lower end portion of the second shaft constituting member 2b together with the rubber ball 9 (FIGS. 1A, 2A, 3A, and 6). a)).
According to the configuration of the cane 1 of the present embodiment, the legs 7a, 7b, and 7c can be housed in the lower end portion of the second shaft component 2b together with the rubber ball 9 as described above, so that the appearance during use is improved. A self-supporting cane that is not different from a normal cane can be provided.
尚、第2シャフト構成部材2bを、より下方にスライドさせて、ストッパ手段6のピン6aを、より下方の貫通孔5b,・・・に挿入させれば、杖1の長さをより長くすることができる。すなわち、本実施の形態の杖1の構成によれば、使用者の体格に合った長さに調整することが可能な自立杖を提供することができる。 If the second shaft component 2b is slid further downward and the pin 6a of the stopper means 6 is inserted into the lower through-holes 5b,..., The length of the cane 1 is increased. be able to. That is, according to the structure of the cane 1 of this Embodiment, the self-supporting cane which can be adjusted to the length suitable for a user's physique can be provided.
図4(a),図6(a)の状態から、ストッパ手段6のピン6aを貫通孔5aから抜いて溝5の上に載せ、第2シャフト構成部材2bを上方にスライドさせていくと、ピン6aが溝5の上端に達したときに、ゴムまり9がシャフト2の下端から飛び出して球状に膨らみ(図1(b),図2(b),図3(b),図6(b)参照)、これにより、脚体7a,7b,7cが三角錐状に展開保持されて、杖1が自立可能な状態となる。 When the pin 6a of the stopper means 6 is removed from the through hole 5a and placed on the groove 5 from the state of FIGS. 4 (a) and 6 (a) and the second shaft component member 2b is slid upward, When the pin 6a reaches the upper end of the groove 5, the rubber ball 9 protrudes from the lower end of the shaft 2 and swells into a spherical shape (FIGS. 1B, 2B, 3B, 6B). )), The leg bodies 7a, 7b, and 7c are developed and held in a triangular pyramid shape, and the cane 1 is in a state where it can stand on its own.
以上のように、本実施の形態の杖1によれば、第2シャフト構成部材2bを第1シャフト構成部材2a上で上下にスライドさせるという簡単な手動操作により、自立可能な状態と通常の使用状態とを切り替えることができる。従って、本実施の形態によれば、モータ等を必要としない、軽量で低コストの自立杖を提供することができる。 As described above, according to the cane 1 of the present embodiment, a state in which the second shaft constituent member 2b can be self-supported by a simple manual operation of sliding the second shaft constituent member 2b up and down on the first shaft constituent member 2a and normal use.
