Abstract

A skate comprises a main body 10 having front and rear sockets 16,17 locating compression springs 91,92 therein. Wheels 40,50 are mounted on supports 20,30 which are pivoted on the main body by pivots 25,35. The compression springs are held in place by discs 93,94 and connecting members 95,96 which are themselves pivotably mounted on the supports 20,30. Also present are two torsion springs 60,70 which abut the shafts 26,36 on the connecting members and the base of the main body and which reinforce the action of the compression spring. The skate may have a brake and the rollers can be one-way.

Description

Title : IMPROVED SKATE The present invention relates to a bounding skate which after touching the ground and suffering a downward pressing force can bound up by a greater force.

In the recent skating sport, in addition to the simple rolling over the ground, a more live and entertainlng eautiBul bounding up movement is also included. However, the existing skate is not provided with any design for enhancing the bounding movement.

U. S. Patent No. 2901259, Swiss Patent No. 132639, Netherlandish Patent No. 129196 and U. S. Patent No.

894846 are all related to the brake mechanism of the skate.

U. S. Patent No. 4602801 d-iscloses a controlling device by which the heel of the skate can be depressed to brake the skate. However, such skate includes very complicated structure in which rollers are respectively disposed on three parallel shafts. U. S. Patent No.

2225361 discloses a skate in which a swinginq brake-shoe is disposed at the heel. When the brake-shoe is engaged with a cushion member, the skate is braked.

All the above Patents are irrelevant to the mechanism for bounding movement of the skate.

It is therefore a primary aim of the present invention to provide a bounding skate including a main body, a front and a rear supports pivotally connected with the front and rear ends of the main body, and a front and a rear wheels respectively rotatably connected with the front and rear supports. The main body is disposed with a front and a rear receptacles for locating-two compressian springs therein. Two supporting disks are disposed under the bottom ends of the springs and two connecting members are disposed under the supporting disks. Two resilient members are disposed under the receptacles via two shaft pins. When the front and rear wheels touch the ground and suffer a downward pressing force, the compression springs and--the resilient members are depressed and the main body is downward collapsed, enabling the user to bound up with less strength and by a greater height.

The present invention can be best understood through the following description and accompanying drawing, wherein : Fig. 1 is a perspective assembled view of the present invention : Fig. 2 is a perspective exploded view of the present invention ; Fig. 3 is a sectional assembled view of the present invention ; Fig. 4 shows an alternative one-way roller of the skate of the present invention ; Fig. 5 is a front view of the casing plate of the one-way roller according to Fig. 4 ; and Fig. 6 is a sectional view showing the assembly of the one-way roller, of Fig. 5 and the support of the present invention.

Please refer to Fig. 1. The skate of the present invention mainly includes a main-body 10, a front.. and. a rear supports 20, 30 assembled with the main body 10 and d a front and a rear wheels 40, 50 respectively assembled with the front and rear supports 20, 30.

Please refer to Figs. 2 and 3. The main body 10 is disposed with a front and a rear top planes 11, 12, two lateral walls 13, 14 and a bottom face 15. Referring to Fig. 3, two receptacles 16, 17 are respectively def ined under the front and rear top planes 11, 12 for locating two compression springs 91, 92 therein. The upper ends of the compression springs 91, 92 abut against the inner bottom walls of the receptacles 16, 17, while the lower ends thereof abut against the surfaces of two supporting disks 93, 94.

The front support 20 includes two spaced clamping plates 21, 22 rearward extending therefrom. Each clamping plate 21, 22 is formed with a pivot hole 23, 24 at rear end. The main body 10 is formed with two opposite holes 108 corresponding to the pivot holes 23, 2-4, whereby a front transverse shaft 25 is passed through the pivot holes 23, 24 and the opposite holes 108 so as to pivotally connect the front support 20 with the main body 10. The front wheel 40 is rotatably connected with the front support 20 via a wheel shaft disposed at front end of the front support 20. similarly, a rear transverse shaft 35 is passed through two pivot holes 33, 34 of two clamping plates 31, 32 of the rear support 30 and through two opposite holes 109 of the main body 10 so as to pivotally connect the rear support 30 with the main body 10. The rear wheel 50 is rotatably connected with the rear support 30 via a wheel shaft disposed at rear end of the rear support 30.

Two connecting members 95, 96 are respectively connected with bottom ends of the supporting disks 93, 94. Each connecting member 95, 96 is formed with a transverse hole 97, 98 near lower end thereof, whereby a shaft member 26, 36 is passed through a shaft hcle 27, 37 of each of the front and rear supports 20, 30 and through two opposite holes 18, 19 of the main body 10 so as to secure the connecting member 95, 96 thereto. The main body 10 is further formed with two through holes 101, 102 beside each of the receptacles 16, 17. A shaft pin 103, 104 is passed through the through holes 101, 102 and each of two resilient members 60, 70. The resilient member 60, 70 preferably includes a coil-like central portion and pressing strips extending from the central portion to two sides. A first end 61, 71 of each of the resilient members abuts against the aforesaid shaft member 26, 36, while a second end 62, 72 thereof abuts against the bottom face 15 of the main body.

In the preferred embodiment of the present invention, a depression portion 105 is disposed at rear end of the main body 10 extending into a socket 38 or the rear support 30 and connecting with a brake block 80. One end of the brake block 80 is pivotally connected with a shaft pin 39. The inner surface of the brake block is axially disposed with a brake lining 81 for the rear wheel 50. A lug 82 is disposed on the outer surface of the brake block, whereby a shaft pin 106 is passed through a hole 107 of the depression portion 105 and the lug 82 so as to connect the brake block and the depression portion. Accordingly, when the heel of the skate suffers a downward pressing force, the rear wheel can be braked and stoppe.

In another embodiment of the present invention, the front and rear wheels of the skate are replaced by one- way rollers. Referring to Figs. 4 to 6, the one-way roller includes two casing plates 51 which are assembled together face-to-face (referring to Fig. 5). The casing plates 51 are mounted on the front and rear supports-20 (as shown-in Fig. 6). The casing plates 51 have multiple radial plates 52 defining multiple locating sleeves 53. An engaging dent 54 is formed at a radial extension portion of each locating sleeve 53.

Multiple ratchets 55 are respectively assembled with the locating sleeves 53. The ratchets 55 can be deflected and retracted inward or stretched outward about their central shaft 56. As shown in Fig. 4, when the ratchets are controlled and rotated by the front end 57 of the central shaft to inward retract, the roller can rotate clockwise or counterclockwise. While when the ratchets suffer the pulling force of the springs to outward stretch, the stopper portion 59 at the end of the ratchet will engage into the engaging dent 54, permitting the roller to rotate only in one direction.

When the wheels 40, 50 touch the ground and suffer a downward pressing force, the two springs 91, 92 are subject to a compression force. At the same time, the two resilient members 60, 70 are also depressed, whereby the entire main body 10 is downward collapsed with the pivot shafts 25, 35 of the front and rear supports 20, 30 serving as the pivot shafts. When the springs 91, 92 and the resilient members 60, 70 are resiliently restored, a bounding force is exerted onto the main body and the wearer standing on the skate. Therefore, the user can bound up by a greater height.

It is to be understood that the above description and drawings are only used for illustrating one embodiment of the present invention, not intended to limit the scope thereof. Any variation and derivation from the above description and drawings should be included in the scope of the present invention.
