Abstract: A speed reduction mechanism is provided to a strap supporting post having a winding mechanism capable of automatically winding a strap around it; the reduction mechanism includes a rotary member turnable together with the winding mechanism, and a stationary member secured to on top of the post; the rotary member has rubbing bars pivoted to a middle part thereof; the rubbing bars are biased towards the middle part by tension springs; centrifugal force will act on the rubbing bars when the winding mechanism rotates after the strap has been released from stretched position; the rubbing bars are pivoted towards the stationary member when speed of rotation of the winding mechanism is so high that the centrifugal force is greater than force of the tension springs, thus slowing down rotation of the winding mechanism, and preventing the free end of the strap from swing too fast.

Abstract: A leg of a table includes a connecting portion, and an elongated supporting portion. The connecting portion includes two lateral plates secured to bottom of a table's top, and several horizontal portions formed between the lateral plates. The horizontal portions have through holes aligned with each other. Annular walls are formed around the through holes. The annular walls are shaped such that the inner sides thereof taper off towards an upper end of the inner side of the uppermost one. The elongated supporting portion has pads on an upper end, of which the outer sides taper off towards an upper end. The elongated supporting portion is joined to the connecting portion with the pads being inserted into the annular walls; thus, the pads will be forced further into the connecting portion when more weight is placed on the table, making the table more steady.

Abstract translation: 桌子的腿包括连接部分和细长的支撑部分。 连接部分包括固定在桌子顶部底部的两个侧板和形成在侧板之间的若干水平部分。 水平部分具有彼此对准的通孔。 围绕通孔形成环形壁。 环形壁的形状使得其内侧朝向最上面的内侧的上端逐渐变细。 细长支撑部分在上端具有垫，其外侧朝向上端逐渐变细。 细长的支撑部分连接到连接部分，其中垫被插入到环形壁中; 因此，当更多的重量放置在桌子上时，垫将进一步被迫进入连接部分，使桌子更稳定。
