Description
本發明為一種止滑結構，尤指一種斜坡輪子止滑結構，提供人性化自動依據上、下坡度的改變而轉動該平衡組件及該擺錘的相對位置，進而使裝設有本發明之輪子物品能自動具有剎車阻力之效用。 The invention relates to a non-slip structure, in particular to a slope wheel anti-slip structure, which provides humanized automatic rotation of the balance assembly and the relative position of the pendulum according to the change of the upper and lower slopes, thereby enabling the wheel of the invention to be installed. The item can automatically have the effect of braking resistance.
習用技術之輪椅當使用者推動於下坡時，輪椅因為重力作用而會往下滑動，因此使用者須施以一力去克服輪椅下滑之力；上坡時同樣有重力作用而向後滑動，因此使用者同樣需要施力以防止輪椅太快往下移動，縱然是停在原處，使用者同樣需要施力去維持輪椅的位置；若輪椅上有病患或者放置物品時需要耗費更大的體力跟施力，因此習用技術仍有改善空間。 Wheelchairs of conventional technology When the user pushes downhill, the wheelchair slides downward due to gravity, so the user must exert a force to overcome the downward force of the wheelchair; when climbing uphill, there is also gravity to slide backwards, so The user also needs to apply force to prevent the wheelchair from moving down too quickly. Even if it is parked in the same place, the user also needs to apply force to maintain the position of the wheelchair; if there is a patient in the wheelchair or when placing the item, it requires more physical strength. Shili, so there is still room for improvement in the conventional technology.

參閱第1~7圖，本發明為一種斜坡輪子止滑結構，係包括：一平衡組件10，該平衡組件10周圍係呈圓弧狀且其兩側截弧的交界處分別設置一止滑部101，該平衡組件10中心位置處設置一第一透孔161，該第一透孔161向下形成一第一延伸部231；一擺錘12，該擺錘12底部形成扇形並於扇形中間設置一重力調整塊121，該重力調整塊121上方設置一第二透孔162，該第二透孔162向上形成一第二延伸部232；一輪轂14，該輪轂14內部設有一內圈141，且該輪轂14中心位置設置一通孔163；一圓底盤18，該圓底盤18於周邊設置一第一柱體181，於圓心處設置一第二柱體182，其中，該第一透孔161穿設於該第一柱體181，該第二透孔162及該通孔163依序穿設於該第二柱體182並由一鎖固件20鎖固於該第二柱體182上。 Referring to Figures 1-7, the present invention is a slope wheel anti-slip structure, comprising: a balance assembly 10, the balance assembly 10 is surrounded by an arc and a non-slip portion is respectively arranged at the intersection of the arcs on both sides. 101. A first through hole 161 is defined in the center of the balance assembly 10. The first through hole 161 defines a first extending portion 231. A pendulum 12 is formed. The bottom of the pendulum 12 is fan-shaped and disposed in the middle of the fan. a gravity adjusting block 121, a second through hole 162 is disposed above the gravity adjusting block 121, and the second through hole 162 is formed with a second extending portion 232; a hub 14 having an inner ring 141 therein, and A circular hole 163 is disposed at a central position of the hub 14; a circular chassis 18 is disposed on the periphery of the circular chassis 18, and a second cylinder 182 is disposed at a center of the hub. The first through hole 161 is disposed through the first through hole 161. The first column 181 , the second through hole 162 and the through hole 163 are sequentially disposed on the second column 182 and locked to the second column 182 by a locking member 20 .
上述中，該第一延伸部231頂端為一凸部241，該第二延伸部232相對之頂端係為一凹部242，且該凸部241抵頂於該凹部242之左右兩側。 In the above, the top end of the first extending portion 231 is a convex portion 241, and the second extending portion 232 is a concave portion 242 opposite to the top end, and the convex portion 241 abuts against the left and right sides of the concave portion 242.
參閱第4、4A圖，將本發明之該輪轂14設置於一輪椅30上且該輪椅30位於平面時，根據上述，該第一延伸部231頂端為該凸部241，該第二延伸部232相對之頂端為該凹部242，位於該平衡組件10上之各該止滑部101與該輪轂14之該內圈141仍維持 一段距離，因此使用者於平面上推動該輪椅30時，不會有阻力效果且推動順暢不滯礙。 Referring to FIGS. 4 and 4A, when the hub 14 of the present invention is disposed on a wheelchair 30 and the wheelchair 30 is in a plane, according to the above, the top end of the first extending portion 231 is the convex portion 241, and the second extending portion 232 The opposite end is the recess 242, and each of the anti-slip portion 101 on the balance assembly 10 and the inner ring 141 of the hub 14 are maintained. A distance, so when the user pushes the wheelchair 30 on the plane, there is no resistance effect and the pushing is smooth.
參閱第5及5A圖，當該輪椅30位於下坡時，由於該重力調整塊121有一定的質量，因此重力會使其向下進而讓該擺錘12始終朝向地面的位置，而位於該平衡組件10之該第一延伸部231會抵頂於該第二延伸部232上，造成該平衡組件10向逆時針偏轉，此時，位於該平衡組件10上之該止滑部101會向上抵頂於該內圈141上，並產生一摩擦阻力讓該輪椅30不會向下滑動。 Referring to Figures 5 and 5A, when the wheelchair 30 is on a downhill slope, since the gravity adjustment block 121 has a certain mass, gravity will cause it to go down and the pendulum 12 is always facing the ground position, and the balance is at the balance. The first extension 231 of the assembly 10 abuts against the second extension 232, causing the balance assembly 10 to deflect counterclockwise. At this time, the anti-slip portion 101 on the balance assembly 10 is upwardly abutted. On the inner ring 141, a frictional resistance is generated to prevent the wheelchair 30 from sliding downward.
同理，參閱第6及6A圖，當推動該輪椅30於上坡時所產生的棘輪作用能避免上坡推力不足導致輪子向後滑動，係因為重力作用使該重力調整塊121往下進而帶動該擺錘12朝下，而位於該平衡組件10之該該第一延伸部231會抵頂於該第二延伸部232上，造成該平衡組件10順時針偏轉，此時，位於該平衡組件10上之該止滑部101會向上抵頂於該內圈141上，並產生一摩擦阻力讓該輪椅30不會向下滑動。 Similarly, referring to Figures 6 and 6A, the ratcheting effect generated when the wheelchair 30 is pushed uphill can prevent the wheel from sliding backwards due to insufficient thrust of the uphill slope, and the gravity adjusting block 121 is driven downward by gravity. The pendulum 12 faces downward, and the first extension portion 231 of the balance assembly 10 abuts against the second extension portion 232, causing the balance assembly 10 to be deflected clockwise, and at this time, on the balance assembly 10 The anti-slip portion 101 will abut against the inner ring 141 and generate a frictional resistance so that the wheelchair 30 does not slide downward.
參閱第7圖為本發明之另一種實施例之態樣，該第一延伸部231頂端為該凹部242，該第二延伸部232相對之頂端為該凸部241，且該凸部241抵頂於該凹部242之左右兩側。 Referring to FIG. 7 , in another embodiment of the present invention, the top end of the first extending portion 231 is the concave portion 242 , the opposite end portion of the second extending portion 232 is the convex portion 241 , and the convex portion 241 is abutted. On the left and right sides of the recess 242.
上述中，該輪轂之該內圈形狀可為平滑狀、鋸齒狀或棘齒狀(圖未示)。 In the above, the shape of the inner ring of the hub may be smooth, serrated or ratcheted (not shown).
