摘要： A climbing apparatus comprising a base, an upright member extending vertically upwardly from the base and having first and second sides and first and second carriages slidably locatable along the first and second side of the upright member. The apparatus further comprises a foot support associated with each of the first and second carriages, the carriages being rotatable supported by the carriage; and an upright engaging member extending from each foot support to selectably engage the upright when the foot support is rotated to a first orientation and to disengage from the column when the foot support is rotated to a second orientation.

摘要： A step stool includes a handrail attached to one side with non-skid steps that make it safe when standing on the step stool. Stabilizing bars are connected to the step stool to prevent it from tipping over due to a user placing his weight on the hand rail when standing on the step stool.

摘要： A moveable climbing system includes at least one step, a first set of legs, a second set of legs, a first set of wheels operatively connected to the first set of legs, a second set of wheels operatively connected to the second set of legs, and a motor operatively connected to the first set of wheels, configured to rotate the first set of wheels. The climbing system may further include a battery for providing electric supply for the motor. The at least one step may include a rung of a ladder. The at least one step may include a board of a scaffold. The climbing system may further include a motor box housing the electric motor, wherein the motor box may be configured to operatively connect to and disconnect from the at least one step.

摘要： This is ladder that is more user friendly than the arts that are on the market today. This is accomplished by moving the legs of the ladders closer together than present day ladders, and by putting a warning bell on the second step from the bottom warning there is another step below before landing on a solid surface. Adjustable legs are a new feature in this new art of modern ladders. This eliminates time spent looking for a block or other object to put under the leg, thus saving time.Having the steps closer together makes it easier for the elderly and people with shorter legs to ascend and descend the ladder.
摘要翻译： 这是比现在市场上艺术更加用户友好的梯子。 这是通过将梯子的腿移动到比现在的梯子更靠近的地方实现的，并且在底部警告的第二步上施加警告钟，在着陆在坚实的表面之前还有另一个步骤。 可调腿是这种新型现代梯子的新特征。 这消除了花费时间寻找一个块或其他物体放在腿下，从而节省时间。 使步骤更靠近，使老年人和腿部较矮的人更容易上升和下降。

摘要： A selfsustaining ladder, especially designed for use in harvesting fruit from trees, having an arcuate curvature to generally conform to the horizontal curvature of a segment of a fruit tree. The ladder has more than two uprights and the rungs, each of which connect with all of the upright, are spaced at considerable distances apart to provide maximum accessibility, between the rungs, to the fruit.

摘要： A ladder selectively allows or prevents user access to the ladder steps, such that the ladder can only be climbed when such access is allowed. For example, the ladder may only selectively allow ingress into a bathing enclosure, e.g., when operated by an adult, but always allows egress from the bathing enclosure by any user. The ladder includes one or more safety blocks moveable between a safety configuration, in which ingress is prevented or inhibited, and a ladder configuration, in which ingress and egress is permitted.

摘要： A stepladder of the folding freestanding type has steps only toward the upper end thereof and has a step deficient region toward the lower end thereof for receiving a smaller stepladder in nesting relation therewith so that the steps of the smaller stepladder provide user access to the steps of the larger stepladder. A nested sequence of such stepladders with all except the smallest one of that sequence being step deficient in a lower region may include several such ladders thereby providing the user with the option of selecting a ladder of a desired height from among several possible heights with the required storage space for the several ladders being the same as the required storage for space for a single ladder of the greatest height. Braces, supports and locking arrangements for fastening each ladder within the step deficient region of the next larger ladder are also disclosed.

摘要： A folding step ladder has a pair of front legs with a pair of back legs pivoted thereon, below which are upper and lower steps pivotably secured to the front pair of legs. A pair of spaced apart links are pivotably secured to the upper step at points rearwardly of its pivotal connections to the front legs and the other end of each link is pivotably connected to the rear legs at points below the upper step. The link members each have an abutment at this point which forms a stop for the ladder on unfolding. This is arranged through the action of a pair of arms, the upper ends of which are pivotably connected to the upper step rearwardly of the pivotal link connection thereto; the lower ends of the arms are pivotably secured to the rearward portion of the lower step. Each arm extends downwardly between an individual link and its adjacent rear leg but forwardly of the abutment to engage thereon when the ladder is unfolded.
摘要翻译： 折叠阶梯具有一对前腿，其中一对后腿在其上枢转，下方的上下台阶枢转地固定到前一对腿。 一对间隔开的连杆在其与前腿的枢转连接的后方的点处可枢转地固定到上台阶，并且每个连杆的另一端在上台阶下方的点可枢转地连接到后腿。 连杆构件在这一点上都具有一个支座，这对于展开阶梯可以形成梯子的止挡。 这是通过一对臂的动作来设置的，其一端的上端可枢转地连接到其枢转连杆连接件向后的上部台阶上; 臂的下端可枢转地固定到下台阶的后部。 每个臂在单独的连杆和其相邻的后腿之间向下延伸，但是当梯子被展开时，其向上延伸以抵靠在其上。

摘要： A brace for converting an extension ladder into a stepladder. The brace comprises a pair of spaced clamping members for securing two diverging extension ladder sections. The clamping members comprise a pair of rods having U-shaped clamps at each of their ends. The pairs of rods are secured by channel sections. An adjustable device for rigid bracing of the ladder sections is provided.
