Description

Field of the Invention The present invention relates to a resistance training device, in particular a device for resistance training of a human; more particular but not exclusively a device for providing all-body exercises. Background Many people in many societies are increasingly prone to enjoyment of exercise. There are many forms of exercise, which each concentrate on different muscular groups and preferred outcomes. Prior Art US 10 456 615 (ANTHONY) discloses a pneumatic exercise device comprises a resistance base and an ergonomic handle. The resistance base provides resistance to movement of the ergonomic handle. The ergonomic handle is coupled to a shaft projecting from a top of the resistance base. Another end of the shaft is coupled to a piston within an air cylinder inside a housing of the resistance base. A pressure differential of an air caused movement of the piston creates the resistance. An amount of resistance may be changed by sliding a resistance adjustment lever on a side of the housing. The angle of the ergonomic handle is adjustable by pressing a pivot release on the side of the ergonomic handle. The pneumatic exercise device may include an auxiliary platform used to elevate a user's feet during exercise. US 2014 0 148 316 (TSUCHIO et al) discloses a personal resistance exercise device for providing operable motion resistance and static resistance to pulling and pushing motion of a user, comprising: a pneumatic cylinder having a cylinder upper end and a cylinder lower end; said cylinder upper end comprising an aperture therethrough; a foot pad extending outward from said cylinder lower end and having a first and second foot pad surface; a piston member comprising an elongated length, a handled upper end, and a lower piston end; said piston end slidably positioned within said cylinder and said piston member length adapted to be slidably positioned within said aperture of said cylinder upper end; an air valve disposed on said cylinder for allowing air to communicate therefrom and thereinto as said piston end is advanced and retracted, respectively; at least one pair of vertically aligned resistance band attachment means comprising an upper resistance band attachment means disposed on said piston member and a lower resistance band attachment means; said upper resistance band attachment means and said lower resistance band attachment means adapted to support an elastic resistance band between said piston member and said cylinder. GB 0 307 614 (MINOGUE et al) discloses exercise equipment comprising: an elongate hollow member defining a chamber; a reciprocating piston mounted in said chamber to sealably slide from an outwardly extended position to an inwardly retracted position, the piston defining a first volume and a second volume either side of the piston within the chamber; an aperture to allow a restricted efflux of air from one if said volumes as the piston is moved in one direction and a restricted influx of air into said one volume as the piston is moved in the other direction; said movement being resisted by a force due to a pressure differential created across the aperture; and force measuring means located within said chamber. Summary of the Invention According to the present invention there is provided a resistance training device comprising: a pneumatic cylinder; a frame; and a plunger for the cylinder; wherein the cylinder comprises an adjustment means for restriction of airflow; the plunger comprises a plurality of displaceable handles; and the frame comprises a plurality of legs, a handle height variation means, and an articulation means to allow redeployment of the legs in relation to the height of the handle. In this way the device may be adjusted to ensure that the plunger offers a preferred exercise profile for a user. In some embodiments of the device the device comprises receiving saddles for a user’s feet, such that the user may be enabled to pull against their feet, stretching their whole body or just exercising their lower body or upper body. In some embodiments of the device the device comprises feet extending from and located on the legs, which feet may provide the saddles as well as stabilising the device on the ground. In some embodiments of the device the legs are telescopic. In some embodiments of the device the frame allows vertical movement of the cylinder in relation to the legs, for example sliding movement so as to adjust the height of a handle attached to the cylinder. It may be envisaged that the cylinder slides in and out of a tube depending from the collar. In some embodiments of the device the adjustment means enables restriction of airflow into cylinder. In this way a user may control the difficulty of pulling the handles up so as to exercise preferred groups of muscles to a preferred amount. In some embodiments of the device the adjustment means enables restriction of airflow out of cylinder. In this way a user may control the difficulty of pushing the handles down so as to exercise preferred groups of muscles to a preferred amount. In some embodiments of the device the device comprises displaceable handles, which may be extended laterally, or rearranged to a more comfortable angle for use. In some embodiments of the device for example the handles comprise a folding hinge, so as to allow the handles to be angled. In some such embodiments of the device the device comprises a locking means for the hinge, which may be envisaged to comprise a grub screw or the like, so as to ensure that the handles do not move in use and jeopardise the exercises. In some embodiments of the device the device comprises a rotatable handle unit, which may be envisaged to be wholly displaceable. For example this unit may be envisaged to be attached to the top of the device in use, so as to provide a gripping means that can rotate, for example around a vertical axis provided by the device. Rotation thereby allows the user to grip the gripping means, handle or handgrip from a plurality of attack angles. This may enable single-handed exercise movements, so as to allow the user to exercise still further muscle groups.
