Definitions

  • An object of this invention is to provide an exercise device for simulating climbing which is compact and lightweight and capable of being conveniently stored and transported.
  • a further object of this invention is to provide such a device which may offer a wide variety of incremental heights that are easily and quickly adjustable to accommodate the need of the particular user.
  • a further object of this invention is to provide an unobstructed platform surface so that the user can easily step on and off in any direction.
  • a still further object of this invention is to provide such a device which may be mass produced inexpensively in a simple design.
  • a yet further object of this invention is to provide such a device which may be used as an elevated platform for warm-up exercise.
  • a device of the type disclosed in co-pending application serial no. 533,004 which is modified in its leg structure.
  • the device includes a horizontal platform having a downwardly and outwardly extending peripheral apron with a leg detachably mounted at each corner of the platform.
  • each leg is reverseably mounted so that it may be selectively mounted in one of two positions. As a result, it is possible to provide height adjustability in accordance with a particular orientation of the legs with respect to the platform.
  • the legs are inclined and of generally straight construction having a narrow section at each end.
  • the length of the narrow section at one end is longer than at the other end so that when the narrowed section is inserted into a complementary mounting structure of the apron the platform will be elevated in accordance with the extent to which the leg extends from the apron.
  • the leg is of curved construction and includes two portions which are generally perpendicular to each other with each portion being of differing lengths than the other portion.
  • the height adjustability is achieved in accordance with the selection of the portion that will be vertical when the legs are mounted in place.
  • the present invention is directed to the type of aerobic climbing step/bench as described in co-pending application serial no. 533,004 filed June 6, 1990, the details of which are incorporated herein by reference thereto.
  • a basic difference between the present invention and the device as described in Serial no. 533,004 is that the present invention achieves is height adjustability through the use of sets of legs which are selectively mounted to the platform in a reverseable manner so that differing heights are achieved with the orientation of the legs with respect to the platform.
  • FIGS 1-4 illustrate a device 10 which may function as a step/bench in accordance with this invention.
  • device 10 includes a base 12 in a form of a horizontal platform 14 having a downwardly and outwardly extending apron 16. If desired apron 16 may be perpendicular to platform 14.
  • a leg 20 is mounted at each corner 18 of apron 16.
  • each leg 20 is generally of tubular form and includes a central portion 22 and a pair of end portions 24,26. End portions 24,26 are made narrower than central portion 22 so as to snugly fit in complementary shaped and dimensioned pockets or channels 28 at each corner of apron 16. Where apron 16 is perpendicular, legs 20 are not inclined.
  • Each leg 20 is inclined at the same angle as apron 16. Legs 20 are so structured that narrow portions 24,26 may both be selectively positioned in pocket 28. As is apparent, narrow portion 24 is of shorter lengths than narrow portion or extension 26. Legs 20 are dimensioned with respect to pocket 28 and apron 16 so that the lower edge of each pocket rests against shoulders 30,32 respectively of legs 20 when a narrowed portion or extension 24 or 26 is inserted into the pocket.
  • Figure 3 illustrates the practice of the invention wherein the shorter narrowed extension 24 is inserted in pocket 28.
  • the height of base 12 is 4 inches.
  • the perpendicular height of leg 20 is, for example, 10 inches with the perpendicular height of extension 24 being 2 inches and the perpendicular height of extension 26 being 4 inches. Accordingly, when legs 20 are mounted to base 12 in the position shown in Figure 3, the overall height of the top surface of platform 14 would be 10 inches. When, however, the legs are mounted in the reverse position, as shown in Figure 4, with the longer extension 26 being inserted in pocket 28 then the overall height of the top surface of platform 14 is 10 inches.
  • Figure 5 illustrates a modification of this invention wherein an extra set of legs 36 is provided having a disc like central portion or flange 38 and a pair of narrowed extensions 40,42.
  • the overall perpendicular height of leg 36 is 6 inches while the perpendicular height of narrowed extension 42 is 4 inches and the perpendicular height of narrowed extension 40 is 1 3/4 inches.
  • the top surface of platform 14 would be at a height of 6 inches when legs 36 are mounted as shown in Figure 5 and would be at a height of about 8 1/4 inches when legs 36 are mounted in the reverse position.
  • the two sets of legs thereby permit height adjustability of the top surface of platform 14 from 4 inches when no legs are mounted to 12 inches when leg 20 is mounted in the position shown in Figure 3 with incremental adjustability of about 2 inches being provided therebetween.
  • Legs 36 would be provided along with legs 20 to provide a complete set of legs.
  • FIG. 7 illustrates an advantageous feature of this invention wherein the legs may be stored on the underside of base 12 within the periphery of apron 16 during conditions of non-use. As illustrated each leg 20 is held in place in any suitable manner with the illustrated manner being spring clips 44. Although not shown the shorter legs 36 may also be stored within the periphery of apron 16 by being mounted such as by spring clips to the underside of platform 14 or to the inner side of apron 16.
  • FIGS 8-11 show a variation of this invention wherein the legs 50 are of a different type of structure than legs 20 or 36.
  • pocket 28 is dimensioned to be of complementary shape and size to the extensions of the particular legs. The length of each pocket would also be of generally the same length as the longer extensions 26 or 42.
  • legs 50 are of inverted L-shape and the mounting is achieved by forming a slot or recess 52,54 in the perpendicular extensions 56,58 of leg 50.
  • the recesses 52,54 are dimensioned to snugly engage the downwardly extending apron 16 of base 12.
  • the overall height of the top surface of platform 14 when longer extension 56 is vertically disposed as in Figures 8-10 would be 12 inches.
  • the overall height of the top surface of platform 14 would be 10 inches.
  • Figure 13 illustrates a variation of this invention wherein the leg 60 is formed as a hollow block 62 having a long side 64 and a shorter side 66 with a pair of channels or recesses 68,70.
  • the overall height of top surface 14 is for example, 6 inches.
  • the position of legs 60 is reversed so that longer sides 66 are vertical the overall height or elevation or top surface of platform 14 would be 8 inches.
  • height adjustability is possible with the provision of legs 50 and 60 over a range of 4 inches when no legs are used to 12 inches when leg 50 is used in the position used in Figures 8-10.
  • Legs 60 would be provided ;with legs 50 to provide a complete set of legs.
  • Figure 14 illustrates the legs 50 stored on the undersurface of base 12 during conditions of non-use.
  • the undersurface of base 12 includes raised projections 72 which snugly fit in the respective recesses or channels 52,54 of legs 50 to mount the legs in place.
  • Projections 72 could be formed from or lined with resilient material to assure a tight yet detachable fit in the respected recesses. Other forms of mounting could be used such as spring fingers as previously described.
  • the shorter leg 60 could be mounted on the inside wall of apron 16.
  • the invention thus provides a convenient manner of achieving height adjustability through the use of reverseably mounted legs so that a range of height adjustment is selectively attainable by selectively using the platform without any legs or by selectively mounting the legs to the platform and adjusting the height in accordance with the orientation of the respective legs in their connection to base 12.
  • the embodiment of Figures 1-7 has the advantage in its simplicity of structure.
  • the embodiments of Figures 8-14 has the advantage of providing an elongated surface under platform 14 to facilitate the stability of the mounting and support for base 12. As shown in Figures 10,11 and 13 the lower surface of platform 14 rests directly on the inwardly extended horizontal portion of each leg.
  • leg 50 in the illustrated embodiment of this invention is intended to have an overall height which would result in the top surface of platform 14 being either 10 or 12 inches, depending upon the orientation or leg 50. This is achieved by dimensioning the bottom of longer extension 56 being 8 inches below the base of recess 52 while the bottom of shorter extension 58 is 6 inches below the base of recess 54. Accordingly, the 4 inches added height of base 12 would make the resultant overall height 10 inches and 12 inches respectively.
  • leg 60 is dimensioned so that the length between the base of channel 70 and the lower surface of side 64 is 2 inches, while the distance between the base of channel 68 and the lower edge of side 66 is 4 inches. By providing other dimensions different height adjustments for platform 18 are possible.
  • apron 16 is illustrated as being angularly inclined.
  • the invention may be practiced where apron 16 is generally perpendicular to the top surface of platform 14.
  • Figures 8-14 for example, illustrate such an embodiment.
  • the respective channels 52,54 68,70 of legs 50 and 60 could be angularly arranged where apron 16 is inclined.
  • the Invention may be summarized as follows:
