Abstract: A climbing tree stand having a continuous length adjustment for the tensile member passing around the tree. FIG. 1 shows the stand, incorporating a foot platform and a seat platform. Each platform is bound to the tree by a flexible tensile member. Each tensile member is removably connected to a first and second slider. Each slider rides along a bar. The slider is ordinarily clamped firmly to the bar. It can only be moved by the user pressing a lock plate and sliding it along. Thus, the tensile member can be adjusted without ever releasing it from the platform. In addition, if the user should accidentally release his or her grip on the slider, the slider will lock itself in position and prevent the platform dislodging.

Abstract: A ladder is composed of a vertical support structure and a set of rungs. In the present invention, the vertical support structure is formed by a sailboat mast or other vertical object to be climbed. A set of step housings are attached to the mast. Each step housing contains an inclined hole sized to receive a removable rung. A set of removable rungs are provided. Each such rung has an insertion cylinder and a step. The insertion cylinder is placed in the inclined hole on one of the step housings. Interlocking mechanical features lock the removable rung in the step housing. The user can thus install a number of removable rungs in order to easily climb the sailboat mast or other vertical object.

Abstract: A ladder incorporating a vertical support structure and a set of removable rungs. The vertical support structure is formed by stacking a series of interlocking sticks. The sticks incorporate features allowing the removable installation of the rungs. The rungs are small and light, so that a set of such rungs may be easily carried by a user. The vertical sticks generally remain attached to the object to be climbed—such as a tree or pole. When the user wishes to climb the object, the user installs the rungs as he or she climbs. The rungs are then removed upon descent. In this manner, unauthorized climbing of the object is inhibited. Locking features are also included to prevent unauthorized access by another person having a set of removable rungs. Several different embodiments of the removable rungs are disclosed. The common feature of all these embodiments is the fact that the rungs cannot come loose from the vertical stick while they are under load.
