Description

ONLINE SHEETS / CONVERTIBLE PARALLELS DESCRIPTION OF THE INVENTION The present invention relates to sporting goods, and is particularly related to skates. The field of the invention is that of the skids that have wheels. Skates are used that have wheels for sports, exercise and recreational activities. They are well known and two varieties of roller skates are used: - V - L wheels in line or parallel wheels. These skid designs typically have four wheels, any of all four are in line, so that all the planes of the wheels are coplanar, or parallel two by two, or in a quadrangular arrangement. The skate also includes a closed element for the foot or shoe with a base or frame, which rotatably supports the axle of the wheels. The online arrangement gives the user the feeling of ice skates, while the parallel arrangement is more stable. Both arrangements are popular, 20 being some activities more suitable for inline skates, for example, running on external roads, playing on a hockey field, and other activities for quadrangular or parallel skates, for example, skating on sinuous domes, skaters training. 25 The portion of the closed element for the foot or shoe of the skate is similar for both arrangements. However, the wheel support portions of the * ~~ Skates are typically made from a fixed frame that rotatably supports the axles of the wheels. The angular contrast between the in-line array and the parallel array requires that the wheel support portions of these skids be dramatically different. Also, the closed portion for the foot or shoe is fixed differently to each type of wheel support arrangement. For example, with -Not inline skates, two elongated plates can serve as trunnions for all wheel axles. However, it is not practical to provide parallel runners with common trunnions for the increased width between the wheels of the parallel runners, although each pair of the parallel wheels can share a common axis. For a skater who uses both arrangements, a pair of skates for each arrangement __ • must be obtained. A known convertible skate allows the replacement of the set of wheels in line with a blade for ice skating. This structure currently requires that the wheel assembly be removed and a separate blade assembly adapted to convert the skids. With this design, you can use the same closed element to stand with any arrangement.

However, this design requires the skater to carry spare parts that are removed and replaced. In addition, while this design allows the substitution of a support for the wheels in line and a support for a blade for ice skating, this does not provide a support for the parallel arrangement of the wheels. Another skate is disclosed in Swiss Patent Document No. 189,894, which discloses a skate with a quadrangular arrangement of 2 x 2, where each pair of two wheels mounted on a common axis can rotate on a pivot with relation to the base. This arrangement allows the wheels to change their general alignment in relation to the base. However, because the wheels are mounted on a common axis, an inline arrangement is not possible. What is needed is a skate that can be quickly converted from an inline array to a parallel array. The present invention provides a skate that can be converted from a wheel-to-wheel configuration in which all skate wheels are coplanar to a parallel wheel configuration, and vice versa. In a simple operation, the configuration of the wheels can be converted manually using only the replacement of the equipment in the same skids. Both inline skates and quad skates are used for sporting purposes as well as for recreational purposes. The traditional quad skate has enjoyed great popularity for a long time, while - - that the widely spread marketing of inline skate is relatively recent. The quad skate is particularly suited for use in places such as winding skating rinks, while inline skating tends to prevail an external use. Generally, the places and uses of the two types of skates are characteristic of each skate. A selection of a > The skater of an inline or quad skate often depends on the type of activity in which the skater wants to play. Then, the skater will incur the expense of buying more than one pair of skates, and the inconvenience of having to change the skates depending on the activity 5 that the skater wants to play at any given time. The present invention employs a wheel frame mounted on posts fixed to the base of the closing element for the foot or shoe. The wheel frame supports the wheels and is rotatable around the pole. The positioning mechanism connects the post with the wheels, which are supported by the wheel frame. The wheel frame is rotatable between at least two positions, and the connection of the wheels to the post through the positioning mechanism ensures that the angular orientation of the wheels is maintained. A positioning mechanism, mainly a tension rod, has a predetermined position in relation to the post and the wheels, so that the wheels are positioned angularly in relation to the post. So the tension rods 5 keep the wheels always parallel to the length of the closed element for the foot or shoe in the previously determined positions. By turning the wheel frame, the wheels can be placed in any of an inline array, where the wheel planes are -2. coextensive, and a parallel arrangement, where the wheels are parallel and coaxial. Other positioning mechanisms include, forks, gear assemblies and externally mounted rods. By mounting the wheel frame on the post, 5 many different varieties of closed elements for the foot or shoe can be used with the invention. The posts, in conjunction with the frame of the wheels, provide the support for the portion of the enclosed foot or shoe element to increase the stiffness of the closed foot or shoe element and increase its structural integrity. In one embodiment, two poles are used with frames for corresponding wheels and each wheel frame supports two wheels. This allows four wheels to be used in line, which can be quickly changed to a two-by-two parallel arrangement. One method of effecting the change is by releasing a nut, which engages with the frame for the wheels, by turning the frame, • and tightening the nut. Another method comprises a post with an orientation mechanism to release and secure the frame. The invention comprises, in a form thereof, a skate with a closed element, at least two wheels and a wheel frame fixed to the closed element and supporting the wheels in a rotating manner, which is characterized by a mechanism of placement. The wheels are oriented by the positioning mechanism in at least one of the arrangements, a first inline array and a second parallel array. The closed element includes a post extended from a lower surface of the element closed, and the wheel frame is rotatably disposed around the post. The post includes a threaded portion, and the skid further comprises a nut that is threadably engaged with a threaded portion of the post to secure rotationally the position of the wheel frame. The post may also include a portion of elongated diameter that supports a spring to orient or urge the frame to the post. Another feature of the invention comprises an alignment mechanism, which guides the in relation to the post and can define a plurality of discretely aligned positions for the frame related to the post. One embodiment of the positioning mechanism includes two tension rods that connect the post and the wheels. 5 The tension rods have a predetermined length, which maintains the angular position of the wheels in relation to the post, without considering the angular position of the frame. Another modality of the positioning mechanism, includes gears arranged inside the frame "" And that they connect the post and the wheels. One of the modalities of the gear-based positioning mechanism includes a band that operably connects the gears. Yet another embodiment of the positioning mechanism includes an elongate member arranged externally of the frame, which connects a wheel of a frame with a wheel of a second frame, so that ^ The rotation of the two frames is synchronized. The positioning mechanism provided for the wheels shall be maintained at an angular position corresponding to the longitudinal direction of the closed element through the rotation of the frame. The invention also provides a brake mechanism fixed to one of the wheels to decrease the speed of the skate. The wheels are adapted to the frame by means of the wheel support, which includes a transverse piece U-shaped in die with the shaft, which supports each wheel in a rotatable manner. The brake mechanism is mounted on a wheel support, and includes a cantilevered arm pivotally fixed to the 5-wheel support adjacent to the wheel. The cantilevered arm has an end with a friction surface disposed adjacent to the wheel. The other end of the cantilevered arm includes a wheel rotatably mounted. The invention also includes a mechanism for U fork removably connected between the post and the wheels, and a drive mechanism or orientation to drive the coupling of the fork mechanism with the post and the wheels, so when deactivating the drive mechanism, the fork mechanism allows the positioning independent of the wheels. An advantage of the present invention is that a single skate can assume the configuration of either an inline or a quad skate. Another advantage is that the present invention can easily and quickly convert from an inline skate to a quad skate and vice versa without removing or adding any equipment. A further advantage is that the present invention can be used in a variety of locations and under a variety of different conditions required for skates with different wheel configurations without the need to invest in different skates. A further advantage is that the same support system and wheels of the present invention can be used without considering the style of the closed element for the foot or shoe. Still another advantage of the present invention is that the material of the closed element that surrounds the post is reinforced and the material of the closed element supports, thus rigidly the wheels and increases the longevity of the skate.

Although the drawings represent the embodiments of the present invention, the drawings are not necessarily to scale and certain features may be exaggerated in order to better illustrate and explain the present invention. The exemplification set forth herein illustrates the preferred embodiments of the invention, in various forms, and such exemplification was not structured as limiting the scope of the invention in any way. The preferred embodiment disclosed below is not intended to be exhaustive or to limit the invention -Lf-- with the precise forms disclosed in the following detailed description. Rather, the modalities are selected and described so that other persons skilled in the art can use their teachings. According to the present invention, the skate 2 includes a closed element for foot 4, frame for wheels , supports for wheels 52, and wheels 50. The element - ^ closed for foot 4 (Figures 1 and 29 include a shoe 5 rigidly fixed to the base of the shoe 6. Although a closed element for foot is shown, a person with skilled in the art will appreciate that a closed foot element may be used with the present invention. At the bottom of the portion of the closed element of the skate 2, wheels 50 can be arranged with the wheels 52 in any of the line arrangement of the Figure or the quadrangular parallel arrangement of Figure 2. The skate 2 can be quickly converted between these arrangements by a simple replenishment of the equipment below the base of the shoe 6. The wheel frame 10 is rotatably disposed around the center post 30, which has a threaded portion 32. The central post 30 is fixed rigidly to the base 34. The central post 30 extends through the hole 13 of the closed element or shoe holder 11. The shoe holder 11 is -x ^ -. interposed between the wheel frame 10 and the base of the shoe 6 and is rigidly fixed to the base of the shoe when fixing the wheel frame 10 to the base of the shoe 6 and to the post 30. The lower surface of the shoe support 11 may have undercut slots that receive and constrict tension rods 18 in a tight position in any of the in-line or parallel arrangements. and Alternatively, the same purpose can be achieved without the grooves by the bottom surface of the shoe holder 11, which consists of an elastic material, which constricts the tension rods 18. The nut 36 is threadably screwed into the threaded portion 32 to hold the rough frame 10 against the base 34. The wheel frame 10 also includes insertion elements 12 rotatably disposed in a Frame opening 10. The insertion elements 12 function as a collar and allow the wheel support 52 to rotate in relation to the wheel frame 10. Preferably, the insertion elements 12 have a larger diameter in a range of 7.5 mm at 44.5 mm. The O-rings 5 or circular packs 19 may optionally be disposed between the insertion elements 12 and the frame 10 to provide elastic damping to the micro-movement of the insert 12. The rod 20 is rigidly fixed to the insert 12, and to the - O. 50 wheels as described below. The insertion elements 12 include holes 14, which rotatably receive the tension rods 18, which rotatably place the insertion elements 12 relative to the frame 10. The holes 14 are located at a predetermined diameter, preferably about 2.5 mm, away from the larger diameter, the perimeter and external, of the insert 12, so that the relative rotation of the insertion elements 12 and the wheel frame 10 is maintained, so that when you turn the wheel frame by 90 °, the wheels 50 automatically follow the rotation to keep the length of the enclosed element parallel 4. The tension rods 18 functionally connect the post 30 and the wheel supports 52, and are one precise length to conform the predetermined engineering positions of the skate and the wheel frame. The connection of the tension rods 18 with the post 30 and the wheel supports 52 serves as a positioning mechanism, which provides for the automatic positioning of the wheels 50. The preferred length of the tension rod 18 is equal to the length of the distance between the axial center of the post 30 and the axial center of the insert 12, plus the diameter of the tension rod 18. The center of the holes 14 is preferably arranged at an angle of 45 ° from the axial center of its insertion element 12 in relation to the reference line extended through the center of both insertion elements 12, when arranged in the wheel frame 10. Also the holes 15 in the collar 70, as described in greater detail below, they are located at a previously determined diameter of the axial center of the collar 70, preferably about 2-5 mm away from the greater diameter of the collar 70, and are also arranged at 4 5 ° of the axial center of the collar 70 in relation to the same reference line. The wheel supports 52 include transverse members 56 rigidly fixed to the rod 20 by the nut 22. Alternatively, the rod 20 can be connected to the wheel supports 52 by a rivet or other suitable fastening element. The arms 54 are rigidly fixed to the transverse piece 56 to form a support piece configured in U. The shaft 58 is forming a stump between the arms 54. The wheel 50 rotates about the axis 58 and is secured to the shaft 58 by the nut 60. 5 Alternatively, the wheel 50 may be connected to the shaft 58 by a rivet or other suitable fastening element. With the rod 20 rigidly fixed to both the insert 12 and the wheel support 52, the pivoting movement of the insert 12 within the frame ! * - for wheels 10 causes the angular position of the wheel 50 to change in relation to the frame for wheels 10. However, the structure and arrangement of the tension rods 18 ensures that the angular position of the wheel 50 in relation to the closed element 4 remains substantially constant. To configure the skid 2 in a particular configuration of wheels, the nut 36 is untightened and the wheel frame 10 is rotated around the post 32 to the desired position. The rotation of the support for wheels 52 and the wheel frame 10 together cause the skate to assume the configuration of either a quad skate or an inline skate. As shown in Figures 5 and 6, the finger or projection 17 at one end of the tension rod 18 is inserted pivotally in the holes 15 of the collar 70, and the collar 70 is fixed to the central post 30. The finger or projection 17 on the other end of the tension rod 18 is inserted pivotally into the hole 14 of the insertion element 12. It is prevented from Tension rod 18 comes out of this position due to the small space available when the nut fixes the frame 10 to the base 34, and due to the constriction by the shoe holder 11, when the nut 36 is tightened. As shown in Figures 5 and 6, the rotation of the wheel frame 10 pivots the tension rod 18 around the V ^ ~ collar 70, changing the configuration of the wheels 50 from a position in line to a parallel or quadrangular position and vice versa. To obtain the configuration of in-line roller skates shown in Figure 1, the nut 36 is loosened, and the wheel frame 10 is rotated to a position parallel to the base of the shoe 6. When the frame * •. for wheels 10 is rotated, the tension rod 18 pivots around the collar 70, turning the wheel 50 on the pivot contemporaneously to a position parallel with the shoe base 6. The nut 36 is then tightened on the threaded post 32 to maintain the wheel frame 10 in a position parallel with the base of the shoe 6. Optionally, the wheel frame 10 may include a notch or other structure for dock with base 34 in this position when the nut 36 is sufficiently tight. To obtain the configurations of parallel wheel skates shown in Figure 2, the nut 36 is loosened, and the wheel frame 10 is rotated to a position perpendicular to the base of the shoe 6. When the wheel frame 10 is rotated, the tension rod 18 pivots about the collar 70, pivoting about the pivot contemporaneously with the wheels 50 to a position parallel with the base of the shoe 6. The nut 36 Ifr * - is then tightened on the threaded post 32 to maintain the wheel frame 10 in a position perpendicular to the base of the shoe 6. Optionally, the wheel frame 10 may include a notch or other structure for engaging with the base 34 in this position, when the nut 36 is tight enough. The embodiment of the present invention shown in r the drawings includes four wheels; Figure 1 shows the four wheels in a line, while Figure 2 shows the wheels in the four corners of a square or rectangle. Alternatively, a skate defined by the present invention can have virtually any skate wheel configuration, for example, combinations of 2x1 parallel wheels and 1x2 inline wheels, or 2x3 parallel and 1x6 line wheels, or even combinations of odd numbers of wheels for each foot, such as configurations of parallel wheels 1 + 2x1 and in line 1x3. The embodiment of the present invention shown in Figures 1 and 2 show a closed element with closed geometry, such as a shoe, with fixed dimensions. In fact, the closed skate element can have any closed geometry as in a shoe, the closed element can have an open geometry such as a sandal, or the closed element can be structured and arranged to be attached to a shoe or boot. In addition, the closed element may be of fixed or adjustable dimensions. Various variations of the present invention are shown in the remaining Figures 8-28 and are described in greater detail below. Figures 8-11 show several structural modifications to the base 34 ', which aligns the frame 10'. , These alignment features; corresponding tabs 72 and slots 73 (represented as equally spaced groups of six,) pins 74 and holes 75 (represented as equally spaced groups of four), polygonal projection 76 and notches 78 (represented as octagonal), or similar features; they restrict the rotational movement of the frame 10 'in relation to the base 34'. Although the tabs 72 and projections 76 are shown as part of the base 34 ', and the pins 74 and the projections 76 as part of the frame 10', one recognizes that these corresponding elements can alternatively be constructed in the frame 10 respectively. 'and the base 34'. Also each total number of the male portion of each of the alignment elements or correspondence 72, 74 and 76 may be less than the total number of its corresponding female elements 73, 75 and 78. In order that the frame 10 ' and the base 34 'rotate 90 ° in a mutual relationship, at least two of the female alignment elements should be spaced at an angle of 90 °, which can be achieved by equally spacing a selected or equal number of male alignment elements . With more than two such female elements, the corresponding male alignment elements can temporarily rest in an intermediate orientation and prevent random orientation of the wheels. The frame 10 'also includes edges 80, which engage the periphery of the base 34' in the in-line or quadrangular configuration. The base 34 'includes a gear 82 for coupling with the additional embodiments of the positioning mechanism of the present invention, which are described in greater detail below. Another variation of the present invention comprises a fork mechanism, which allows an individual adjustment of the orientation of the wheels. The forks 84 and 86 are mounted on the posts 32 'within the frame 10' 'and 10' '' of Figures 12 and 13, respectively. The upper surface of the forks 84 and 86 may have alignment elements as disclosed in the aforementioned Figures 8-11 to locate the wheels. Similar alignment elements can be incorporated between the frame and each wheel support to individually align the wheels. The springs 88 and 90 are disposed between the forks and the frame, or alternatively the spring 92 may be disposed between the frame and the base 34". When the nut 36 is loosened, the elastic drive of the springs separates the forks from the frame so that each wheel can be independently aligned in a parallel or in line arrangement. As an alternative to the nut 36 that is tightened on the post 32, a modified center post can - elastically connecting the frame to the base, as shown in Figure 14. In this embodiment, the central post comprises a support plate 94, a sleeve 96 and a connector 98. The connector 98 extends through the base 34 'for connecting to the support plate 94. In the embodiment disclosed, the connector 98 has external threads, which engage correspondingly with the internal threads 103 of the sleeve 96, which is also in a threaded coupling with the connecting portion 100 of the support plate 94. The connection by means of the sleeve 96 can be facilitated by the elastic insert 102 disposed within the sleeve 96 between the connector 98 and the connection portion 100. The spring 104 is disposed about of the sleeve 96 with one end adjacent the elongated diameter portion of the post support plate 94 and the sleeve 96, and the other end of the spring 104 is adjacent to the frame 10 '. Under typical operating conditions, the spring 104 urges the frame 10 'to the base 34'. For the rotation or reorientation of the wheel supports 52, the frame 10 'can be pulled down against the force of the spring 104 and out of the coupling with the base 34' so that the frame 10 'can be repositioned either in the online or parallel arrangement. Once replenishment is achieved, the spring 104 urges the frame 10 'back into engagement with the base 34'. Alternative embodiments of the positioning mechanism of the present invention employing the gears shown in Figures 15-18. Figure 15 shows a frame 10"'which houses a set of gears 106. The gear set 106 includes a gear of the post 108 fixedly connected to the pole 94 and the base 34', and the wheel gears 110 they are connected to the wheel supports 52. The rotation of the pole gear 108 is transferred to the gears of the wheels 110 through the intermediate gears 112, which are mounted on the frame 10"'' '. The contacts between the gears 108, 110 and 112 synchronize the orientation of the wheel supports 52 when the frame 10"'' 'is rotated about the post 94. Although the intermediate gears 112 are not essential for the operation of the mechanism of placement, its inclusion allows all gears to have a smaller size. The embodiment of Figures 17 and 18 is similar to the embodiment of Figures 15 and 16 described above, except for the replacement of the meshed band 114 as the motion transfer mechanism within the gear assembly 106 '. The meshed band 114 is disposed within the frame 10"'' and engages the gears of the pole 108 and the gears of the wheels 110. Similar to the embodiment of Figures 15 and 16, the rotation r of the frame 10 '' '' causes the meshed band 114 to move and rotate the gears of the wheels 110 in a synchronized manner. Another embodiment of the present invention, wherein the positioning mechanism is located externally to the frame, is shown in Figures 19-22. An elongate member such as rods or panels 116 are fixed at specific locations on the periphery of the wheel supports 52, so that the entire frame assembly 10 and the rods 116 move together when one of the frames 10 is rotated in relation with its base 34. The rods 116 of the exemplary embodiment are disposed perpendicular to the axis of the axis 58. As indicated by 5 the arrows 118, the parallel or quadrangular arrangement of Figure 20 is transformed into an in-line array of Figure 19 by the clockwise rotation of the frame 10. Similarly, the arrows 120 of Figure 21 illustrate how to rotate the frame 10 counterclockwise to transform a quadrangular or parallel array into an in-line arrangement, such as that shown in Figure 22. Thus, each of the rods 116 is connected to two wheel supports 52 on the same side of the skate, and maintains the same distance and longitudinal orientation through the rotation of the frame 10. The present invention also includes a brake 122 as shown in Figures 23-28- The brake 122 comprises a cantilever arm 124 having a wheel 126 at one end and a friction surface 128 at the other end. The support plate 130 is fixed to the wheel support 52 and to the pivot of the supports 132 or integrally formed therewith, around which the cantilevered arm 124 moves. The brake 122 can be fixed to one of the front or rear wheels 50 or both, and adjacent to the tip or heel region of the skate 2, so in an in-line arrangement, the wheel 50 having a brake 122 should be any of the first and last wheels. In the quadrangular or parallel arrangement, the brake is simply on the side of the front or rear wheels. The braking action is activated by the skater that includes the skate 2, so that the wheel 126 is in contact with the surface on which the skate 2 is transverse. The contact of the wheel 126 pivots the arm 124 so that the friction surface 128 comprises the wheel 50. The friction between the friction surface 120 and the wheel 50 decreases the rotation of the wheel 50, thus applying the braking action. In the online arrangement, the braking wheel is the only wheel that turns on the skating surface. The brakes of a different conventional skate, which create friction directly with the skating surface, the friction surface of the present invention is not in contact with the skating surface, thus reducing a greater wear on the brake. In addition, the brake of the present invention still allows the user to skate while braking, providing the skater with greater control of skidding and braking handling.
