Outer sole with removable sliding system

Abstract

The present invention concerns the field of garments, namely the shoes sector, especially relating to children, although it is likewise applicable to young people and adults. The object of the present invention is an outer sole (1), on which are inserted two structures, a first one enabling one user to slide when he is contacting the ground, moving as if he were on skates, and a second one enabling the user to move in a conventional way. The first structure, which enables a movement in a rolling mode, consists in a frame (2) containing a wheel (3) and, on one end, presents a front locking member (4) and, on another end, a locking member (5) for disengagement of the frame (2) by pressing downwards.

DETAILED DESCRIPTION OF THE INVENTION

(9) The object of the present invention is one outer sole (1) on which a rolling mechanism (18) is inserted, consisting in a frame (2) and at least one wheel (3), which, in contact with the ground, enables the user to slide, moving as if he were using a skate or, alternatively, inserts one frame (13) that enables a conventional moving mode.

(10) Both frames (2)(13) inserted in the outer sole (1) are removable, i.e., when the user so wishes, he may remove the frame (2) or frame (13), by pressing downwards the locking members (5) or (15) provided in the frames (2)(13).

(11) The possibility of removing the frames (2)(13) by disengagement, just by pressing on the locking members (5) or (15), enables the user to easily alternate the two possible ways of moving himself, by disengaging and engaging the frames (2)(13).

(12) It is now important to detail the composition of the main components of the system, i.e., the outer sole (1), the rolling mechanism (18) and the frame (13) and how they are engaged in and disengaged from the outer sole (1).

(13) The outer sole (1) exhibits a ramp (10) on its rear end, which shows an engagement portion (12), preferably in the form of a cavity. The outer sole (1) does also show an opening (9) to receive a frame (2) or (13) and adjacent to the ramp (10) on one face, and in the opposite face it shows at least one recess (8), which is preferably a slot.

(14) The inclination of the ramp (10) is, preferably, between 29° and 35°.

(15) The rolling mechanism (18) consists in a frame (2) and at least one wheel (3), which is crossed by a metal shaft (6) to attach the wheel (3) to the frame (2).

(16) The frame (2) shows at least a front locking member (4) on one end, intended to be engaged in the outer sole's (1) recess (8) a braking plate (7) on the other end, which accompanies the geometry of the ramp (10), a locking member (5) embossed on the surface opposite the braking plate (7), for attachment to the engagement portion (12) of the outer sole (1).

(17) In an alternative configuration of the invention, the rolling mechanism (18) may be constituted by two wheels (3) on line or by two wheels (3) parallel to each other.

(18) The surface of the braking plate (7) shows anti-wear slots to reduce the speed of the shoe where the outer sole (1), object of the present invention, is integrated while it is moving.

(19) The frame (13), shows one base with flaps (11) and at least one locking member in the front (14) on one end, to be engaged in the recess (8) of the outer sole (1), a braking plate (17) on the other end, accompanying the geometry of the ramp (10), a locking member (15) embossed on the surface opposing the braking plate (17), for attachment to the locking member (12) of the outer sole (1).

(20) It is now important to detail the engagement and disengagement of the frame (2) of the rolling mechanism (18) on the outer sole (1), so that the system may be either converted into a rolling mode, or into a conventional walking mode.

(21) To convert the system into a moving mode, the attachment of the frame (2) to the outer sole (1) is initiated by engaging at least one front locking member (4), in at least one recess (8) of the outer sole (1) and, by pressing upwards, the attachment of the locking member (5) into the engagement portion (12) is performed, thus providing a full integration of the frame (2) in the outer sole (1).

(22) This described form of engaging the frame (2) in the outer sole (1) ensures the stability and good performance of the system, object of the present invention.

(23) When the user wishes to remove the frame (2), he presses the locking member (5), downwards until he disengages it from the engagement portion (12) maintaining the pressure in the same sense and removing the frame (2) from the outer sole (1).

(24) Without the rolling mechanism (18) in place, i.e., in a conventional walking mode, the user may install a frame (13) in a way similar to the engagement of frame (2) of the rolling mechanism (18), since it has the same essential elements for engaging and disengaging.

(25) The attachment of the frame (13) to the sole (1) is initiated by the engagement of at least one front locking member (14), in at least one recess (8) of the outer sole (1) and, by pressing upwards, the attachment of the locking member (15) is performed on the engagement portion (12), thus providing a full integration of the frame (13) in the outer sole (1).

(26) The frame (13) acts like a lid, which, besides protecting the receiving elements of the outer sole (1) when it is in a conventional walking mode, prevents the accumulation of dirt inside the outer sole and promotes stability to the user's locomotion.

(27) In a preferable embodiment, the locking members (5) (15) present an upper curve forming an opening with the basic surface of the shoe, thus facilitating the positioning of the pressure force.

(28) In addition, the frame (13) may be in plastic material and, on the base contacting the ground and on the surface of the braking plate (17) there are slots to prevent the wear due to walking on the ground.
