The skate further includes a device for temporarily supporting the single frame in a stable position when the shoe is not associated with the frame. The device can be deactivated by the engagement of the shoe with the frame, so as to allow the user to use the skate.
Description




BACKGROUND OF THE INVENTION




The present invention relates to an inline skate.




Conventional skates are constituted by a shoe, produced for example by injecting plastic material, which is associated with a usually U-shaped frame supporting a plurality of inline wheels.




The problem that has arisen regarding the use of said skates is the fact that they can be used only for skating, thus forcing the user to remove, before putting on the skates, the shoes that he usually uses for normal walking.




An inline skate marketed by the Italian company MGM under the trademark “HYPNO” is known as a partial solution to this drawback. In said skate there is a shoe which can be detached with respect to a supporting and pivoting frame for a plurality of mutually inline wheels.




An engagement element, such as a pin, is provided at the frame for a grip element which is constituted by a blade arranged below the sole of the shoe, which is locked with respect to the frame by virtue of the presence, to the rear of said frame, of an H-shaped rod whose ends are transversely pivoted to the frame at one end and are transversely pivoted, at the other end, to a lever which interacts with a suitable element associated with the shoe.




Among the various drawbacks of this type of shoe there is also, in addition to structural and constructive complexity, the fact that the user, in order to be able to associate the shoe with the frame, is forced to grip said frame so as to correctly mutually couple the base of said frame to the sole of the shoe, activating the corresponding connection means.




Likewise, if the shoe is uncoupled from the frame, the frame must be supported by the user.




Additionally, these operations occur in conditions which are not always easy for the user, and the user must in any case bend down or, also when sitting, must bend both the leg and the trunk to move his or her hands, which support the frame, toward the sole of the shoe, subsequently performing a pushing action with the foot which must be compensated by manually engaging the frame.




SUMMARY OF THE INVENTION




The aim of the present invention is to solve the above-described problems, eliminating the drawbacks of the cited prior art, by providing a skate which comprises a frame and a shoe which is detachably associated therewith and in which said connection or disconnection of the shoe with respect to the frame can be performed easily and quickly by the user.




An important object of the present invention is to provide a skate in which the user can optimally position the shoe on the frame while standing.




Another important object of the present invention is to provide a skate in which said coupling and uncoupling between the shoe and the frame can occur also if the resting surface is inclined, such as in a downhill road.




Another important object of the present invention is to provide a skate which does not require the user to perform particular movements or physical efforts to achieve optimum positioning of the shoe on the frame.




Another object of the present invention is to provide a skate which is structurally simple, reliable and safe in use.




This aim, these objects and others which will become apparent hereinafter are achieved by a skate comprising a frame provided with means for detachable connection to a shoe and with which wheels are associated, characterized in that it comprises a device for temporarily supporting said frame in a stable position which can be deactivated when said shoe is coupled to said frame.

DESCRIPTION OF THE PREFERRED EMBODIMENT




With initial reference to the above

FIGS. 1-5

,


1


designates a skate comprising a shoe


2


, for example of the type preferably comprising a soft upper


3


below which a sole


4


is associated.




Said sole rests, in the particular illustrated embodiment, below the toe region


5


and the heel region


6


, at a first base


7


and at a second base


8


of a frame


9


which forms a pair of first wings


10




a


and


10




b


between which two or more wheels


11


are freely pivoted and are thus arranged mutually in line.




The shoe and/or the frame have suitable means for their mutual detachable coupling. Merely by way of example,

FIGS. 1

to


5


show an embodiment provided with connection means disclosed in the unpublished Italian Patent Application No. TV97A000131, by this same Applicant. The connection device includes a lever


12


, which has two facing free ends


13




a


and


13




b


pivoted to the rear of the second base


8


and cooperates with a torsion bar or spring


14


which is suitable to force said lever


12


toward the region


15


of the heel of the shoe and to engage at a suitable base


16


formed to the rear of the sole


4


.




At the region


17


of the tip of the sole


4


there is provided a suitable seat for coupling to a fixed ring


18


which protrudes from the first base


7


.




The reference numeral


19


designates the device for temporarily supporting the frame


9


in a stable position: said device is constituted, in the particular embodiment shown, by a U-shaped element which forms a third base


20


and a pair of second wings


21




a


and


21




b


which are laterally adjacent to the first wings


10




a


and


10




b


of the frame


9


and are pivoted transversely thereto by means of a suitable pivot


22


proximate to the second base


8


.




A sleeve


23


is rotatably associated with the third base


20


coaxially thereto, while suitable fittings


24




a


and


24




b


, made of plastics or rubber, are associated with the free ends of the second wings


21




a


and


21




b


. The shape and length of said fittings allow optimum resting on the ground in the regions adjacent to one of said wheels.




Advantageously, the device


19


is further constituted by a spring


25


which is arranged coaxially to said pivot


22


and the ends whereof are rigidly coupled at said second wings


21




a


and


21




b


. The spring is suitable to force a clockwise rotation of the device, so as to make the fittings


24




a


and


24




b


interact with the ground when the shoe is not associated with the frame.




A seat


26


is further formed at the second base


8


and is suitable to accommodate the sleeve


23


when the shoe is associated with the frame


9


.




In this condition, shown in

FIG. 1

, the sole interacts with the sleeve


23


, forcing it into the seat


26


; this produces a rotation of the second wings


21




a


and


21




b


so as to lift them with respect to the ground and place them preferably parallel to the first base


7


and to the second base


8


.




It has thus been observed that the invention has achieved the intended aim and objects, a skate having been provided which comprises a device which allows to keep the frame in a stable vertical position with respect to the ground when the shoe is not associated therewith: this allows the user to quickly and easily associate the shoe with the frame while standing upright, since said frame is arranged in the optimum condition for resting the shoe thereon.




When the user disengages the shoe from the frame, the temporary support device is automatically activated into the stable position of the frame without any specific intervention on the part of the user.




The illustrated embodiment further allows the user to remove the shoe from the frame also in particularly demanding conditions, such as for example if the road slopes downhill.




The skate according to the invention is of course susceptible of numerous modifications and variations, all of which are within the scope of the same inventive concept.




Likewise, the materials and the dimensions that constitute the individual components of the device and the structure may also be the most pertinent according to specific requirements.




Thus, for example, the tips of the fittings


24




a


and


24




b


can have a conical shape or can in any case have a base whose dimensions allow to achieve optimum frame support. The location of the device can be varied according to specific requirements. The skate can further provide for the use of even more than one temporary support device, variously applied at one of the parts that constitute the frame.





FIGS. 6-9

illustrate a second embodiment for a skate


101


which is again constituted by a shoe


102


composed of an upper


103


below which a sole


104


is associated. The sole


104


can be arranged, at the tip and heel regions, on a first base


107


and on a second base


108


of a frame


109


between the first wings


110




a


and


110




b


whereof suitable wheels


111


are freely pivoted.




In the particular illustrated embodiment, the means for detachable connection between the shoe


102


and the frame


109


are constituted by a substantially L-shaped lever


112


, one end of which interacts with an abutment


116


formed to the rear of the sole


104


.




The lever


112


is articulated to a tension member such as a cable


127


which is associated at a plate


128


associated with the frame


109


so that it can slide along the longitudinal axis.




Said plate


128


is forced to slide toward the region


105


of the tip of the shoe by a suitable cylindrical helical compression spring


125


, which is interposed between a first tooth or seat


129


and a second tooth or seat


130


formed respectively in said plate


128


and in said frame


109


in the region of the second base


108


.




Slots


131


are formed at the lateral surfaces of the plate


128


, preferably lie on a plane which is parallel to the plane of the first wings


110




a


and


110




b


and along the same transverse axis; the axis of said slots is arranged at right angles to the ground.




The third base


120


of the device


119


for temporarily supporting the frame in a stable position when the shoe is not associated therewith is accommodated within said slots


131


.




In this case too, the device


119


comprises second wings


121




a


and


121




b


which are arranged outside the first wings


110




a


and


110




b


of the frame


109


and are pivoted thereto by means of a suitable pivot


122


.




Suitable fittings


124




a


and


124




b


are associated with the tips of the second wings


121




a


and


121




b


and interact directly with the ground when the shoe is not associated with the frame.




This embodiment, too, achieves the intended aim and objects, since when the shoe is not associated with the frame the spring


125


pushes the plate


128


forward and this forces the rotation of the device


119


so that the fittings


124




a


and


124




b


interact with the ground, thus supporting the frame in a stable and vertical condition.




When the user associates the shoe with the frame, and therefore when locking occurs by means of the lever


112


, the plate


128


is pulled and slides backward, simultaneously loading the spring


125


and producing, by virtue of the presence of the slots


131


, the rotation of the device


119


and the lifting of the fittings


124




a


and


124




b.






It is of course possible to provide other embodiments, for example of a simplified type in which the activation and/or deactivation of the support device occur by means of a direct manual intervention of the user on said support device.




The device can, for example, be of a telescopic type in which one end is associated with said frame and the other suitably shaped end interacts with the ground.
