This invention relates to skateboards, and more particularly to a foldable skateboard.
A growing number of people use skateboards as a means for commuting, for example, between home, work, school, and the like. A conventional skateboard typically consists of a rigid deck with front and rear truck assemblies attached thereto. A user stands upon the deck, and may control the direction in which the skateboard is traveling by shifting weight to certain places about the board. Conventional skateboards are also by their nature bulky and difficult to carry when not in use. The bulkiness can lead to problems, for example, at households where skateboards are left out in the open. Someone or something may accidentally knock the skateboard into household objects or someone may slip and fall because of the skateboard. This can often lead to injury to a person and damage to property.
Various examples of collapsible or foldable skateboards are described, for example, in U.S. Pat. No. 7,150,461 B2 to Schnuckle et al., on Dec. 19, 2006. Schnuckle describes a skateboard comprising an articulated structure having a foot platform, at least one forward and one rearward ground engaging wheel. The skateboard comprises an articulated foldable structure, a forward ground engaging wheel operably connected to the articulated structure, a rearward ground engaging wheel operably connected to the articulated structure, and a tensioning mechanism including a cable attached at one end to the forward portion and attached at another end to the rearward portion for placing the articulated structure under tension while in a first skating position. The forward portion and the rearward portion are each positionable from the first skating position to a second folded position with the cable becoming slack and wherein the forward portion and the rearward portion each nest within the middle portion while in the second folded position. However, the foldable skateboard of Schnuckle does not resemble a traditional skateboard in terms of materials used, appearance, weight, or performance.
U.S. Pat. No. 7,063,341 B2 to Tsai, on Jun. 20, 2006, describes a collapsible skateboard that includes an upright handle having a lower portion on which is fixedly mounted a bracket. The skateboard also includes a connector having a curved slot having a lower end formed with a horizontal recess, an upper end formed with a vertical recess, and a circular hole under the vertical recess. The skateboard also includes an adjust pin inserted into the vertical recess of the connector and the elongated hole of the bracket, a pivot pin fitted through the circular hole of the connector and the circular hole of the bracket, a spring having an upper end connected to the adjust pin and a lower end to the pivot pin, and a platform on which is fixedly mounted the connector, whereby the skateboard may be folded as desired. However, the collapsible skateboard of Tsai does not resemble a traditional skateboard in terms of appearance, weight, and performance. Furthermore, the skateboard is more bulky than a traditional skateboard because the skateboard of Tsai also includes an upright handle.
U.S. Pat. No. 6,270,097 B1 to Lin, on Aug. 7, 2001, describes a similar foldable skateboard device as the skateboard described by Tsai. Lin describes a foldable skateboard device that includes a board, a holding seat disposed on a front portion of the board, a down tube inserted in the holding seat and connected to an upright handle, a front tube connected to the down tube, a front wheel disposed on a bottom of the front tube, and a rear wheel disposed on a rear end of the board. The down tube has an annular flange. The holding seat has a hollow connection portion receiving a lower end of the down tube, a recess, and an upper confining portion. A pivot pin fastens the hollow connection portion of the holding seat and the lower end of the down tube together. A sleeve is disposed on a middle portion of the down tube. An elastic element encloses the down tube. However, the collapsible skateboard of Lin does not resemble a traditional skateboard in terms of appearance, weight, and performance. Furthermore, the skateboard is more bulky than a traditional skateboard because the skateboard of Lin also includes a down tube connected to an upright handle.
U.S. Pat. No. 6,131,931 to Globerson et al., on Oct. 17, 2000, describes a conventionally shaped skateboard that is divided into three sections, one section measures at about half the length of the skateboard, a middle section measures at approximately the height of the truck and wheel assembly, and a third section constitutes the remaining length of the skateboard. The three sections are hinged together to form a folding skateboard such that when the skateboard is folded, the trucks and wheels of the skateboard are adjacent each other in the interior and in the form of a J-shaped configuration. The sections are locked in an extended, aligned orientation to form a usable skateboard in three embodiments by clips which fit onto the side edges of the skateboard deck and in a fourth embodiment by rods which fit into and slide within cylindrical grooves formed on the bottom of the skateboard deck. The clips and rods are of such a length that they are long enough to span the middle section and a sufficient portion of the two sections to lock the skateboard open but short enough to fit on the longest section without protruding beyond its extremities, when the skateboard is folded. However, the skateboard described by Globerson does not rest flatly upon its longest section, when collapsed. Instead, the skateboard must rest unevenly on the ground. The skateboard is not very compact in nature. Furthermore, extra accessories are needed to store or transport the skateboard, for example, the tie strap and the shoulder strap.
U.S. Pat. No. 5,505,474 to Yeh, on Apr. 9, 1996, describes a folding skateboard including a plurality of frame bars pivotably connected in series by links, two couplings turned about a respective pivot at two opposite ends of the series of frame bars, two wheel assemblies respectively fastened to the couplings to support the frame bars on the ground, and two foot plates respectively fastened to the couplings above the wheel assemblies for the user to ride by legs. However, the folding skateboard of Yeh does not resemble a traditional skateboard in terms of materials used, appearance, weight, or performance.
Therefore, there is a need for a skateboard that resembles a traditional skateboard in terms of materials used, appearance, weight, and performance, that is capable of being compactly collapsed to be stored in small spaces, for example, under car seats, under desks, in backpacks, and the like. The present invention accomplishes these objectives.
The present device is a foldable skateboard comprising a center deck, a front deck, and a rear deck. The center deck has two opposing side edges, opposing top and bottom surfaces, and front and rear ends. The front deck has two opposing side edges, opposing top and bottom surfaces, and a rear end. The bottom surface of the front deck includes a front truck attachment means. The rear deck has two opposing side edges, opposing top and bottom surfaces, and a front end. The bottom surface of the rear deck includes a rear truck attachment means. The foldable skateboard also comprises a pair of articulated pivot means fixed between the center deck and each of the front and rear decks. The side edges of the front deck, center deck, and rear deck being mutually substantially co-aligned when each articulated pivot means is in a first extended position. The top surfaces of the front deck, center deck, and rear deck being mutually substantially coplanar when each articulated pivot means is in the first extended position. The top surfaces of the front and rear decks inverted with respect to the center deck when each articulated pivot means is in a collapsed position.
Each of the articulated pivot means may include two pivot pins and a pivot bar. One of the pivot pins may be fixed to the center deck and the other pivot pin may be fixed to either the front or rear deck. The pivot bar may rotationally capture each pivot pin.
The foldable skateboard may further include a plurality of strengthening pins extending is between the center deck and each of the front and rear decks, each strengthening pin may be captured by one of the decks and may be slidably received in its corresponding opposing deck. Each of the front and rear decks may be longitudinally mutually separated thereby being free from the center deck and thereby able to pivot into the folded or collapsed position. At least one of the strengthening pins and one of the decks may include a latch and lock means, such that when in a locked position the center deck cannot be longitudinally separated from its adjacent deck, and such that when in an unlocked position the center deck may be longitudinally separated from its adjacent deck.
The foldable skateboard may further include a pivot mechanism fixed between the center deck and each of the front and rear decks. Each pivot mechanism may include a pair of articulated pivot means, a center deck mount, and an outside deck mount. With two pivot mechanisms fixed to each of the front and rear ends of the center deck at the center deck mounts thereof, the center deck mounts may be flush with the side edges and top and bottom surfaces of the center deck, and with the outside deck mount of each pivot mechanism fixed to either the rear end of the front deck or the front end of the rear deck. Also, each outside deck mount may be flush with the side edges and top and bottom surfaces of the front and rear decks. When each lock means is in a locked position, the center deck cannot be longitudinally separated from its adjacent deck, and when each lock means is in an unlocked position, the center deck may be longitudinally separated from its adjacent deck. Once unlocked, the adjacent deck is free to pivot around the articulated pivot means between a collapsed position and an extended position.
The present invention is a skateboard that resembles a traditional skateboard in terms of materials used, appearance, weight, and performance, that is capable of being compactly collapsed to be stored in small spaces, for example, under car seats, under desks, in backpacks, and the like. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.
Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words “herein,” “above,” “below” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word “or” in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. Any use of the word “means” herein is intended to invoke means-plus-function limitation in accordance with 35 U.S.C. §112, sixth paragraph, even if the word “means” follows words describing the function.
The foldable skateboard is divided into three sections, a front deck, a center deck, and a rear deck section. The front deck and the rear deck are disposed on opposing sides of the center deck. The front deck and the rear deck sections may each be secured to the center deck, for example, by a spring loaded latch. To fold the foldable skateboard a user may depress an actuator to cause spring plates to compress springs, unlocking a latch located on the underside of the deck to unlock and then separate the front deck and the rear deck from the center deck, prior to folding the skateboard. From its compacted state, the user can restore the skateboard to its full length by unfolding the front deck and the rear deck until they are horizontally adjacent to the center deck. The front deck may be slid towards the center deck until the front deck self-locks to the center deck. The rear deck may be slid towards the center deck until the rear deck self-locks to the center deck.
