Definitions
- the present invention relates to a sole stiffening device, particularly for sports shoes such as climbing boots, ice boots, trekking boots, soccer shoes, or golf shoes.
- the climber when approaching the climb, the climber requires shoes with relatively soft soles, while for climbing the rock face, the shoes must have a rigid sole.
- the user must have different shoes with different characteristics as regards the rigidity of the sole.
- a climber for example, must carry at least two pairs of shoes, thus increasing the weight of the load to be carried and consequently the time and effort required for the climb.
- US Patent No. 4,261,114 discloses a ski boot having, at the sole, which is rigid, two longitudinal seats for bars arrangeable thereat.
- the aim of the present invention is to solve the described technical problems, eliminating the drawbacks of the prior art, by providing a device that allows to quickly and easily stiffen the sole of a sports shoe according to the specific sport to be practiced.
- an important object is to provide a device that can be activated without requiring the user to have any specific tool or instrument.
- Another important object is to provide a device that is structurally very simple and does not substantially alter the shape, bulk, or weight of the shoe whereto it is applied.
- Another object is to provide a device that is reliable and safe in use and has low manufacturing costs.
- a sole stiffening device particularly for sports shoes, characterized in that it comprises a semirigid insole that can be temporarily compressed, with the interposition of at least one flexible element, inside a box-like mid-sole arranged inside said sole.
- figure 1 is a sectional partial side view of a sports shoe having the device, shown in the activation condition, according to the invention
- figure 2 is a detail enlarged side view of the device in the deactivation condition
- figure 3 is a view, similar to the preceding one, of the device in the activation condition
- figure 4 is a top view of the device in the condition of figure 2.
- the reference numeral 1 designates a sports shoe having an upper, or shell, 2 and a sole 3 interacting directly with the ground.
- the stiffening device can be arranged inside the upper, or shell, 2 and is constituted by a box-like mid-sole 5 arranged, optionally in a removable manner, on the sole 3 inside the upper or shell 2.
- the box-like mid-sole 5 has a shoulder 6 arranged perimetrically at least at the heel and toe regions of the foot, and has, in a downward region and advantageously at the heel region 7 and at the metatarsal region 8, first protrusions designated by the reference numerals 9a and 9b arranged within complementarilv shaped seats formed inside the sole 3.
- the stiffening device is also constituted by at least one flexible element 10 that can affect part of the box- like mid-sole 5 or can be constituted, for example, by a plantar insert.
- the insert is shaped complementarilv to said box-like mid-sole and is optionally thinner.
- the stiffening device is also constituted by a semirigid insole 11 that can be temporarily compressed inside the box-like mid-sole 5 by means of the compression of the flexible element 10.
- the insole 11 is shaped complementarily to the box ⁇ like mid-sole 5 without of course having a periraetric shoulder, but having second protrusions 12a and 12b at the first protrusions 9a and 9b.
- the compression of the flexible element and therefore the temporary accommodation of the insole 11 inside the box-like mid-sole 5 occurs by means that are constituted for example by a lever 13, one end 14 whereof is provided with an eccentric element and is pivoted transversely at the stem 15 of a screw 16.
- the screw 16 passes through the box-like mid-sole 5, the flexible element 10 and the insole 11.
- the head 17 of the screw 16 is locked below the box-like mid-sole 5.
- the use of the stiffening device is therefore as follows: in the condition shown in figures 1 and 3, the lever 13 is activated and therefore turned so that its end 14, provided with the eccentric element, pushes the insole 11 inside the perimetric shoulder 6 of the box-like mid- sole 5.
- the lever 13 does not cause discomfort because it is arranged at the protrusions 12a and 12b formed on said insole 11.
- an inner sole 18 can be placed above said insole to increase the user's comfort.
- the sports shoe has a very rigid sole, because no mutual movement is possible among the components of said stiffening device during the rolling phase of walking.
- the flexibility of the sole is in fact strongly limited, because the insole 11 prevents the deformation of the box-like mid-sole 5.
- the lever 13 as shown in figures 2 and 4, thus allowing the insole 11 to protrude beyond the perimetric shoulder 6 of the mid-sole 5.
- the insole 11 moves longitudinally with respect to the box-like mid-sole 5 when the sole flexes, thus making the sole of the shoe more elastic and flexible during rolling.
- the components of the device can in fact deform freely with respect to each other.
- the invention has achieved the intended aim and objects, a device having been provided that allows to achieve the desired stiffening of the sole of a sports shoe by acting quickly and easily at the levers without needing any instrument or tool and simply after merely removing the shoe.
- the user can thus have a single shoe that can effectively vary the rigidity at the sole and can therefore be used for different applications, such as for example climbing or trekking.
- the device is also structurally very simple and does not alter the overall aesthetic appearance of the shoe or its weight.
- the device according to the invention is susceptible of numerous modifications and variations , all of which are within the scope of the same inventive concept .
- the materi al s and the dimensions that constitute the individual components cf the device may also be the most pertinent according to the speci f ic requirements .
