There is no intent to limit to the particular forms disclosed. On the contrary, all modifications, equivalents, and alternatives falling within the scope of the appended claims should be included. Elements of the example embodiments are consistently denoted by the same reference numerals throughout the drawings and detailed description where appropriate.

[0072] Unless otherwise defined, all terms (including technical and scientific terms) used herein are to be interpreted as is customary in the art. It will be further understood that terms in common usage should also be interpreted as is customary in the relevant art and not in an idealised or overly formal sense unless expressly so defined herein.

[0073] In the following description, all orientational terms, such as upper, lower, radially and axially, are used in relation to the drawings and should not be interpreted as limiting on the invention.

[0074] FIGS. 1 to 4 show a simple, lightweight, two-piece adjustable crack system 10, suitable for home use or training areas within climbing gyms. The two units 15, 20 can be used separately or together. Each unit has an inside jamming surface 16, 21.

[0075] It can, for example, be used as a single unit for crack specific exercises and dialling in technique or multiple units can be added together to do full boulder problems and circuits.

[0076] In this embodiment the product comes in a flat packed style which is easily assembled and installed by the user.

[0077] In this embodiment a pack is provided and contains:

[0078] 2×crack trainer halves (24 Screw cups, 48 screws, 2 Base Plates, 4 Uprights, 2 Crack Walls, 4 End Caps, 2 Gripper Bars).

[0079] 1×Glue

[0080] 1×Assembly instruction card

[0081] 1×Training card

[0082] Example Dimensions—Length 800 mm×height 180 mm×width 115 mm

[0083] In this embodiment the wood is cut on a CNC machine.

[0084] All edges and features aside from the crack are rounded for comfort and can be held, stood on and used as other options, to help diversify the climbing and make exercises harder or easier.

[0085] The jamming area is plain wood, for example plywood, which provides a slick jamming feel.

[0086] The crack trainer apparatus has two halves which can be set at a desired width.

[0087] Below are some example widths:

[0088] 1-1.5 inch=thin hand size

[0089] 1.5-2 inch=tight hand size

[0090] 2-2.5 inch=hand size

[0091] 2.5-3.5 inch=baggy and cupped hand size

[0092] 3.5-4 inch=first size

[0093] 4-5 inch=stacked hand size

[0094] The crack trainer apparatus can be used for all abilities, from those just starting out wanting to purely practice technique, to those who have been jamming for years, but want to do some jam specific training exercises.

[0095] FIGS. 5 to 8 illustrate a crack hold formed according to a further embodiment.

[0096] The crack hold is similar to the hold of FIGS. 1 to 4. In this embodiment, however, a soft grip liner/covering 130 is provided and can be installed onto the inside jamming surface within the assembly process, plus easily removed/replaced at a later date if worn. In this embodiment a 1.5 m length of soft grip material is provided.

[0097] An exploded view of the hold is shown in FIG. 9.

[0098] The soft grip material provides a grippy and comfortable crack feel. This option is good for endurance and power endurance workouts, as well as working on technique.

[0099] The soft grip 130 has a pre-adhesive backer in this embodiment.

[0100] It is possible to mix holds and/or hold halves with and without soft grip, as illustrated in FIG. 10.

[0101] Having both options lets the user tailor their training and climbing sessions to the intensity required, enabling them to dial in technique and get stronger quicker.

[0102] FIGS. 11 to 14 illustrate a hold formed in accordance with a further embodiment.

[0103] FIG. 11 shows a unit 215, which in this embodiment is formed as a moulded crack module. In this embodiment the unit is formed from a fibreglass material (e.g. polyethylene or polyurethane based).

[0104] The unit is designed with one flat (e.g. generally vertical and/or at approximately orthogonal to an underlying wall) face 216 that can be used to jam against. The unit has an angled back 217—an approximately 45 degree (for example) slope off the backside of the jamming edge. A longitudinal flange 218a, 218b is provided along each side.

[0105] There is a rounded top edge 219 of the crack module (for comfort).

[0106] In this embodiment the top edge of the crack has rough texture built into the mould to provide friction. All other fibreglass areas are smooth to prevent gaining friction, forcing people to jam.

[0107] The unit has flat ends so they can be stacked together to form a longer crack. Top and bottom edges may be left free to enable stacking. Different shapes may be produced, for example embodiments which have tapered ends.

[0108] Flanges are provided for fixing to the wall on the outside and inside edges of the volumes. Screw fixings may be used for wall attachment.

[0109] The fibreglass unit may be made in a mould and bought as a whole unit.

[0110] Two separate units can be used make up a crack, a left and a right.

[0111] Two separate end caps can be used to make up sloping crack ends: a left 240 (FIG. 12); and right 250 (FIG. 13).

[0112] The hold can, for example, be used on a climbing wall structure, home or commercial. It could be used as a jamming crack or a single unit (like a normal climbing volume would be).

[0113] The crack can be set at any maximum width; this is down to the route setter.

[0114] In this embodiment a minimum width is determined by the inside flange protruding from the crack face.

[0115] FIG. 14 shows a soft grip material sheet 360 formed in accordance with the present invention. An upper (inner jamming) surface is provided with laterally extending corrugations 361.

[0116] In this embodiment the material is moulded into a required shape and texture.

[0117] A specific glue may be used for bonding soft grip to a fibreglass unit, for example.

[0118] In this embodiment the soft grip is provided with a 3D pattern designed to grip the hand. A moulded wave pattern is provided; in this embodiment measured so depth and length coincides with the knuckles and fingertips of climbers hands. Texture on the soft grip helps provide friction.

[0119] The soft grip can be inset into the volume to help protect from wear.

[0120] The soft grip material could be used as a separate product i.e. someone could potentially buy it and use it in their own cracks.

[0121] Soft Grip Pro (SGP) inner jamming surface. SGP is a material specifically shaped and designed for a more comfortable jamming experience. The density is soft to prevent pressure wounds and finely textured to give grip whilst climbing yet won't burn or rip your hands if slipping. The surface is ergonomically shaped to fit the climber's knuckles and fingers in all the different jamming positions. SGP enables the climber to climb freely without having to use tape or gloves.

[0122] FIGS. 15 to 18 show “jam plates” formed in accordance with the present invention.

[0123] FIG. 15 shows a 22 degree jam plate 465. Detail A shows a 2 mm deep counterbore that would accommodate a screw cup/washer. Section B-B Shows a solid piece of material throughout the plate.

[0124] The plates comprise generally rectangular frames with fixing holes so that they can be fixed to a crack volume.

[0125] FIG. 16 shows a 22 degree jam plate (hollow) 470. Section A-A Shows the thin ‘shelled’ construction throughout the plate. Detail B shows a close-up the more complex geometry around the screw holes.

[0126] The frames can receive a sheet of soft grip material 560, for example as shown in FIG. 19.

[0127] The frame may be hollow or may include a back plate against which the sheet is received.

[0128] FIG. 20 shows a middle volume unit 515 formed according to a further embodiment.

[0129] FIG. 21 shows an end cap unit 650 formed according to a further embodiment.

[0130] FIG. 22 shows a smaller finger crack volume design. The volume unit 740 shown has a generally triangular/wedge-shape with an inclined upper-outer face 741 that terminates with a curved “nose” 742 from which an interior face 743 depends that includes a groove/notch/recess 744. The groove/notch/recess is configured/adapted to receive a liner.

[0131] FIGS. 23 and 24 show a finger lock unit 880 embodiment. A nose part 842 is included; a liner can be fitted beneath the nose.

[0132] FIGS. 25 and 26 show an end cap 990 suitable for use with the finger lock of FIGS. 23 and 24.

[0133] FIG. 27A shows a crack volume system comprising volume units that can be used separately, singularly or together.
