An operator may have a significant advantage in terms of the operation of the fitness facility. A user may make a reservation for one of a variety of fitness module boxes at a desirable place and time, and may pay a fee based on the time of use.

A shelter includes: at least two side walls; a back wall; and a roof, wherein the side walls, the back wall, and the roof comprise a material that is weatherproof and insulated, and wherein the shelter is collapsible, detachable, and portable. The shelter can also include at least two side walls, wherein an upper end of the at least two side walls conjoin to form a roof. The shelter is lightweight, detachable, and portable. The shelter can be weatherproof and insulated for permanently or temporarily housing people and/or animals. The shelter can be transported to a desired location and assembled on-site with ease. When the use of the shelter is no longer desired, the shelter can be quickly disassembled and transported to another location.

Modular building units comprise, prior to installation at a construction site, a floor, a ceiling, and a plurality of walls which together define a habitable interior, wherein at least one wall is a reinforced wall capable of spanning a spanning distance of at least 50 feet without underlying support. In some embodiments, reinforced walls comprise one or more reinforcing structures. In some embodiments, the spanning distance is at least 60 feet; in some, at least 70 feet; and in some, at least 80 feet. In a further aspect, a method of building construction comprises the steps of: a) constructing a modular building unit according to the present disclosure at an assembly site; b) transporting the modular building unit to a construction site; and c) installing the modular building unit at the construction site, optionally across a unsupported span of at least 50 feet.

In some examples, a system includes a plurality of posts and a plurality of cage panels, wherein each of the cage panels is removably coupled to one or more of the plurality of posts, wherein a nominal width of each of the cage panels is congruent based on a modulus, wherein an actual width of each of the cage panels is equal to a difference between the nominal width of the cage panel and the width of one of the plurality of posts, and wherein any combination of a subset of the plurality of cage panels coupled in a common orientation to a subset of the plurality of posts has a combined width, between respective centers of end posts of the subset of the plurality of posts, that is congruent based on the modulus.

A collapsible canopy with an improved locking mechanism. The collapsible canopy has at least three supporting legs. The collapsible canopy also has a central lock that is used for locking the collapsible canopy in an unfolded state and permits the collapsible canopy to be folded into a folded state when the central lock is unlocked. An outer retractable unit is connected between each adjacent supporting leg. An inner retractable unit having an inner end is connected between each supporting leg and the central lock. The inner end of the inner retractable unit is connected through the central lock. Reinforcement bars are pivotally connected between the outer retractable units and the inner retractable units, the reinforcement bars function to maintain the shape of the collapsible canopy when the collapsible canopy is in a locked and unfolded position.

The present invention provides a modular system for constructing a structure assembly. The system comprises first and second sidewall components each comprising a set of spaced-apart longitudinally oriented grooves disposed in a first face thereof. The system comprises a plurality of rib components, each rib component having a pair of elongated protrusions extending from opposing sides of the rib component and, each protrusion being shaped to matingly engage with at least the first portion of the groove to connect the first and second sidewall components along a face-to-face direction. The system further comprises two elongate key joint members matingly engaging with two respective additional sidewall components to connect the sidewall components with the additional sidewall components along a transverse direction perpendicular to the face-to-face direction in a side to side relationship.

A structural insulated building unit is provided for constructing a building. The structural insulated building unit includes an insulating core, first and second cementitious panels, and a connecting portion. The insulating core is defined by multiple sides and opposing first and second faces. The first and second cementitious panels are coupled to the first and second faces of the insulating core. The connecting portion is provided on one of the sides of the insulating core, and aligns the structural insulated building unit with an adjacent structural insulated building unit having a complementary connecting portion when constructing a building.

Three dimensional structural frames and enclosures and related methods are disclosed herein. In an example embodiment, an enclosure includes a plurality of three dimensional structural frames and opposing wall portions interconnected by the plurality of three dimensional structural frames, where the wall portions include a plurality of uniform wall sections, where the wall sections include a wall panel portion, a top wall portion, and sidewall portions, where the sidewall portions of the plurality of wall sections are joined to form the wall portions, and where the plurality of three dimensional structural frames are attached to the top wall portions of the wall sections.
