A pitching mound form having a flange structure and a wall structure coupled to the flange structure such that the wall structure extends substantially perpendicular from a plane of the flange, wherein the flange structure and the wall structure form a substantially rectangular cavity, wherein the wall structure has a first height at a first end of the rectangular cavity and a second height at a second end of the rectangular cavity, and wherein the wall structure has the first height for a predetermined length from the first end and then tapers at a predetermined slope to the second end.

Modular floor tiles and modular floor systems are described herein. A floor tile system includes a modular floor tile and a plurality of resilient support assemblies. The modular floor tile includes a top surface layer having a top surface and a bottom surface and a plurality of rigid support portions extending from the bottom surface. The resilient support assemblies are supported against the bottom surface and include an outer resilient support portion having a hollow interior, and an inner resilient support portion positioned centrally relative to the outer resilient support portion.

A form for constructing a foundation for anchoring a pole vault standard to a support structure adjacent to a landing pad includes a first frame and a first plurality of connectors defining a first connecting pattern for coupling to a corresponding connecting pattern of a base of the first pole vault standard. The form is installable in the support structure and operable for use in fixedly connecting the first base of the pole vault standard to the form. A pair of forms may be employed for constructing a pair of foundations for anchoring a pair of pole vault standards to a support structure adjacent to a landing pad.

A ski mat is provided in the present application, comprising a baseplate used for paving a ski field and a plurality of supports mounted on the baseplate to support skiing tools, wherein a mounting base capable of mounting the supports on the baseplate is provided on bottoms of the supports, and a plurality of connectors are provided on a bottom of the mounting base; a plurality of mounting holes capable of clamping the connectors are provided on the baseplate at positions corresponding to the connectors; and, the connectors is clamped into the mounting holes so that the supports are mounted on the baseplate. By clamping the connectors arranged on the supports to the baseplate, it is firmer and difficult to result in a separation of the baseplate and the supports, thus it is safer. The present application also provides a spliced baseplate used for the ski mat.

A modular field that includes a plurality of coplanar wall segments connected together by a plurality of stanchions and a plurality of corner stanchions to connect together wall segments oriented perpendicular to each other. The size of the modular field may be varied by the number and/or size of wall segments. Lights may be connected to the corner stanchions. One or more doors to allow ingress into the modular field may be connected to adjacent wall segments by the stanchions. Goals may be connected to wall segments at opposite sides of the modular field by the stanchions. The stanchions may include a base plate, a main support pole connected to the base plate, a channel receptacle connected to the base plate, a rear plate connected to the main support pole, a frame connected to the rear plate, a front plate, and a clamp connected to the main support pole.

Disclosed is a reversibly installable modular fitness area including a plurality of platform-like islands adapted to support a plurality of systems and equipment in order to allow the user to carry out fitness exercises, the modular fitness area including at least one first central island; at least one second island; at least one third island; at least one fourth island; at least one fifth island; at least one sixth island; at least one seventh island; at least one eighth island; at least one ninth island; the modular fitness area also including an energy supply system adapted to supply power to the electronic components included therein.

An airbag landing device for absorbing an impact of a falling object is disclosed. The airbag landing device includes an inflatable base structure with at least one inflatable closed-cell chamber configured to hold a first fill volume of gas and an inflatable top structure disposed vertically on top of the inflatable base structure. The inflatable top structure includes a central, external chamber, and at least one inflatable open-cell chamber that is configured to sustain a second fill volume of gas. The airbag landing device includes a top cover over the inflatable top structure. The top cover overlays the central chamber to form an air pocket therebetween. At impact, the inflatable top structure exhausts a volume of gas from the air pocket and from the open-cell chamber of the inflatable top structure while the first fill volume of the at least one inflatable closed-cell chamber is maintained.
