Abstract
A module configurable between a chair configuration and a ladder configuration. The module includes first and second interlocking portions, each interlocking portion including first and second longitudinal support members and at least one transverse member therebetween, configured such that the longitudinal support members of the second portion are nestable between the longitudinal support members of the first portion. Orientation of the first and second interlocking portions is configurable between cross-wise interlocking in the chair configuration and linear interlocking in the ladder configuration.
Claims23
A module, configurable between a chair configuration and a ladder configuration, the module comprising:
- first and second interlocking portions, each interlocking portion comprising first and second longitudinal support members and at least one transverse member therebetween, wherein the longitudinal support members of the second interlocking portion are nestable between the longitudinal support members of the first interlocking portion, wherein orientation of the first and second interlocking portions is configurable between cross-wise interlocking in the chair configuration and linear interlocking in the ladder configuration.

12-14. (canceled)
A ladder system comprising:
- a plurality of chair/ladder modules each comprising first and second interlocking portions, each interlocking portion comprising first and second longitudinal support members and at least one transverse member therebetween, wherein the longitudinal support members of the second interlocking portion are nestable between the longitudinal support members of the first interlocking portion, wherein orientation of the first and second interlocking portions is configurable between cross-wise interlocking in a chair configuration and linear interlocking in a ladder configuration,
- wherein the plurality of modules are configured to be longitudinally stackable, and securable, so as to provide a ladder of varying length of modules.
(canceled)
A method for constructing a ladder comprising a plurality of modules each module comprising first and second interlocking portions, each interlocking portion comprising first and second longitudinal support members and at least one transverse member therebetween, wherein the longitudinal support members of the second interlocking portion are nestable between the longitudinal support members of the first interlocking portion, wherein orientation of the first and second interlocking portions is configurable between cross-wise interlocking in a chair configuration and linear interlocking in a ladder configuration,
- wherein, according to the method, a first end of a first module of the plurality of modules is operatively connected to a first end of a second module of the plurality of modules.
A method for converting a module between chair, ladder and/or storage configurations, the module comprising first and second interlocking portions, each interlocking portion comprising first and second longitudinal support members and at least one transverse member therebetween, wherein the longitudinal support members of the second interlocking portion are nestable between the longitudinal support members of the first interlocking portion, wherein orientation of the first and second interlocking portions is configurable between cross-wise interlocking in a chair configuration and linear interlocking in a ladder configuration,
- wherein, according to the method:
- in the chair configuration, the first and second interlocking portions have a cross-wise interlocking configuration and are slidably and rotatably moved to a linear interlocking configuration so as to form the ladder configuration or storage configuration;
- in the ladder configuration or storage configuration, the first and second interlocking portions have a linear interlocking configuration and are slidably and rotatably moved to a cross-wise configuration so as to form the chair configuration;
- and/or
- in the storage configuration, the first and second interlocking portions have a linear interlocking configuration and are slidably moved and/or rotatably moved into a different linear interlocking configuration to form the ladder configuration or are slidably and rotatably moved to a cross-wise configuration so as to form the chair configuration.
