DICK A. MOON BY M ATTORNEY United States Patent G ANTISLIPPING DEVICE Dick A. Moon, Rte. 1, Box 29G, Del Mar, Calif.
Filed Jan. 25, 1960, Ser. No. 4,332
6 Claims. (Cl. 367.7)
The present invention relates to an antislipping device and more particularly to an antislipping device for detachable connection to the soles of footwear.
According to the present invention, there is provided an antislipping device which may be quickly and easily connected to the sales of footwear, thereby adapting ordinary street shoes for use in athletic exercise such as golf and the like. The device is an inexpensive substitute for costly golf shoes and similar types of shoes designed for use in football, baseball and track activities.
The present device comprises a pair of plates which are arranged in overlapping, transversely slidable relation. The plates are each provided with a plurality of calks, and are further provided with sole engaging clips at their outer opposed margins. The device includes means for urging the pair of plates together, that is, increasing the overlapped portion, to securely attach the clips to the sole of the shoe with which the device is associated.
More particularly, one of the pair of plates is provided with a plurality of transversely spaced receiving means or teeth, and the other plate carries a link which has an end element selectively engageable with one of the spaced teeth. The link is pivotally connected to a lever which is pivotally connected to the plate carrying the link, and the lever is operative to move the link in a substantially transverse direction. Movement of the link effects corresponding movement of the end thereof into engagement with the teeth, and continued movement of the lever causes the link to pull the teeth in a transverse direction, thereby increasing the overlap area between the plates.
It is a feature of the present invention that the end of the link is arranged to permit freely slidable transverse movement between the pair of plates so that spacing between the clips of the plates may be adjusted to fit the particular size of footwear with which the device is associated. Thereafter, movement of the lever causes the end of the link to engage the teeth and draw together the two plates to tighten the device on the footwear. An integral keeper is provided on one of the plates to retain the lever in its tightened or locked position. In addition, one of the plates includes a pair of opposed tabs which are formed to provide guideways through which the edge margins of the other plates slide during relative transverse movement. These tabs permit the desired transverse movement, but prevent movement in a direction normal to such transverse movement, which normal movement would undesirably disrupt the operative arrangement of the two plates and the Other objects and features of the present invention will be readily apparent to those skilled in the art from the following specification and appended drawings wherein is illustrated a preferred form of the invention, and in which:
Figure 1 is a plan view of the present device, as viewed from the underside of the footwear with which it is associated;
Figure 2 is a plan view of the device of Figure 1, viewed from the opposite direction and indicating the open position of the device in dotted outline; and
Figure 3 is a view taken along line 33 of Figure 2.
Referring now to the drawings, the antislipping device of the present invention comprises a pair of plates 10 and 12 which are preferably made of flat sheet metal such as stainless steel. Plates 10 and 12 are arranged to fit transversely across the bottom of a shoe sole 14, and include a plurality of opposed sole engaging clips 16, integrally formed of the material of plates 10 and 12 and including an upright portion extending upwardly a distance approximately equal to the thickness of the average shoe sole. The upright portions of clips 16 are formed inwardly to provide flanges to grasp the usual sole of shoe 14.
Link means 30, which is formed of sheet material similar to that of plates 10 and 12, is arranged adjacent the outer surface of plate 12, and includes an end portion 32 formed by bending the end of link means 30 at an angle substantially normal to the flat main body of link means 30. End portion 32, which extends through openings 22 and 24 is then bent over to form an integral tab 34 in coplanar, slidable relation with plate 10. Tab 34 is wider than the width of opening 22 to thereby maintain end portion 32 in position within openings 22 and 24. That is, end portion 32 is narrower than the adjacent sections of link means to maintain end portion 32 in position while yet permitting end portion 32 to be freely slidable within openings 22 and 24.
It is particularly noted that the width of end portion 32 is less than the distance between teeth 20 and the opposite margin of opening 22, but end portion 32 is wider than the distance between teeth 20 and shoulder 28 when plates 10 and 12 are in the superposed relation illustrated. Thus, it will be seen that when end portion 32 is located "invention is simple and efiicient.
,or space between two teeth 2i), preventing relative movement between plates and 12. V
A pair of opposed tabs 36 are-integrally formed at the lower corner of plate 12 out of the edge margins thereof tive transverse movement between plates 10 and 12. Tabs '36 thus serve to maintain the important relative position of the superposed'openings 22 and An L-sh-aped lever 38 is pivotally secured to the end of link means 30 opposite end portion 32, as by a rivet "40 or the like. The leg of lever 38 is pivotally secured "to plate 12, as by a rivet 42, so that as the free end 44 "of lever 38 is swung outwardly, Figure 2, link means 30 will be moved in a substantially transverse direction.
to provide guide ways through which the edge margins *of the overlapping portion of plate 10 slides during rela- Preferably the pivot points at rivets 40 and 42 are arranged such that when end 44 of lever 38 is in the inward "or locked position illustrated in Figure 1, rivet 42. is to an over center relation is provided so that forces tending to move apart plates 10 and 12 will act to pull end 44 inwardly to maintain the locked position thereof.
The operation of the antislipping device of the present The end 44 of lever 38 is swung outwardly to move end portion 32 into the wide end of slot of opening 24. In this position end portion 32 drops down off" camming ridge or shoulder 28 and out of engagement with teeth 20. Plates 10 and '12 are then freely slidable in a transverse direction, and the opposed clips 16 may be grasped by the user to widen the distance between them for fitting the device to the users footwear. With the device in position with plates 10 and 12 against the under surface of the shoe sole, the opposed clips 16 are urged together to bring the inturned flanges of clips 16 in position over the sole of the footwear. The antislipping device is now in position on the footwear, although somewhat loosely. v
Thus, there has been described an antislipping device which is particularly suited for detachable connection to the sole of footwear. The device has the important feature of adjusting itself to various sizes of footwear by an initialrelative movement of plates 19 and 12. Thereafter the novel arrangement of link means 30 with respect to openings 22 and 24 efiects engagement of link means 30 with teeth 20 to tightly clamp plates 10 and 12 to the footwear of the user.
While a preferred embodiment of the invention has been specifically disclosed, it is understood that the invention is not limited thereto as many variations will be readily apparent to those skilled in the art and the invention is to be given its'broadest possibleinterpretation within the terms of the following claims.
