Patent Application
20080029998
The present application relates to boards for sliding on snow such as skis, monoskis, snow boards, and the like, herein referred to generically as skis. The application relates, in particular, to a ski that includes a base plate on which at least one supplemental element is mounted.
The sport of skiing is attracting more and more followers, and has evolved significantly over the past several years. As the skill of the skiers improves, there is a demand for higher quality products. This is, for example, the case for skiing sports.
There are many known models of skis whose base plate includes an elongated beam whose front end is curved upward to form the tip and whose undersurface includes a sole or sliding surface bordered by metal edges.
In spite of the efforts by manufacturers to develop constructions to satisfy their customers, there does not exist, to date, a ski which is convenient to use and has satisfactory characteristics for all types of skiing, in all types of snow, in all types of terrain, for whoever is using it.
Attempts have been made to address this need, such as for example, the constructions shown in French Patents FR 2,670,392 and FR 2,675,391. In the applicant's earlier French Patent FR 2,726,193, a ski construction is proposed in which a platform is affixed to an upper surface of the body of the ski.
The applicant also proposes in U.S. Pat. No. 6,848,703 a raised platform to which the bindings are attached that is divided into two spaced parts that are mounted directly on the base of the ski with an interconnecting bridge. This allows the skier, during turns, to exert a different pressure on each side of the ski.
The applicant also proposes in FR Patent Application FR 04 07955 another improvement for skis in which a supplemental element includes two longitudinal parts which extend parallel and are connected with a transverse connecting part. The supplemental element is fixed, at least in the zone of the ski boot, such that its two longitudinal parts are situated laterally and reside in hollows in the body of the ski.
The present application proposes general purpose skis which include a base plate and at least one supplemental element which cooperates with the base plate in form, dimension, and structure such that together they give the ski the desired characteristics as well as comfort and easy control the skis.
The ski, including a ski, monoski, or snowboard, described in the present application includes a principle part called the body or base plate. A platform which is affixed to the base plate extends in the zone of the boot and is intended to support the bindings for the boot. In addition, it includes an additional supplemental element which extends this platform. This supplemental element is removable attached to the platform by way of a movable interconnection means such that it can be dismounted. The supplemental element includes two longitudinal, lateral arms connected by a transverse connecting part which includes the interconnection means for connecting the supplemental element to the platform. The longitudinal arms include a means of dynamic recall of the base plate.
According to a complementary characteristic, the platform is extended to the fore and/or the aft by a supplemental element. The longitudinal arms of each supplemental element extend laterally compared to a plane of general symmetry to extend forward from the front of the supplemental element or rearwards towards the back of the base plate.
According to other complementary characteristics, the supplemental element extending fore and/or aft has a back end which connects the longitudinal arms by a transverse connection part.
According to another characteristic, the removable interconnection means include a first means integral to the supplemental elements which are intended to cooperate with complementary connecting parts integral with the platform. The interconnection means includes connecting means and means for locking and unlocking the supplemental elements.
Also, it should be noted that visual guide means are provided to simplify connecting the supplemental elements in the correct position and locking them.
Numerous additional advantages and benefits will become apparent to those of ordinary skill in the art upon reading the following detailed description of the preferred embodiments.
The invention may take form in various components and arrangements of components, and in various steps and arrangements of steps. The drawings are only for purposes of illustrating the preferred embodiments and are not to be construed as limiting the invention.
a, 14b, and 15 illustrate alternate embodiments of the supplemental element;
a, and 14b show a first embodiment in which
Although described with reference to skis of the alpine type, it is to be appreciated that the present innovation also applies to other types of skis including monoskis, snow boards, cross-country skis, and the like.
The platform 3 is extended towards the front AV and/or towards the rear AR by at least one supplemental element 6a, 6b. These supplemental elements are independent and can be removed from the platform and can be interchanged with other supplemental elements of different construction or characteristics.
The base plate 2 has its own thickness distribution, edges, width, and stiffness and can be of various kinds and constructions. The base plate includes an elongated beam which can be of any known type or design, such as sandwich type, a box type, a hull type, and the like, as well as combinations of these and other types.
The supplemental elements 6a, 6b are functional reinforcing elements which cooperate with the base plate to confer, with the cooperation, functional characteristics, such as rigidity, inflexion, torsion, etc. used in the sport of skiing.
The front supplemental element 6a which extends forward AV from the platform 3 includes two longitudinal arms 60, 61. Likewise, the rear supplemental element 6b includes two longitudinal arms 62, 63 which extend toward the rear AR from the platform 3.
Each longitudinal arm 60, 61; 62, 63 of each supplemental element 6a, 6b is disposed laterally compared to the plane of general symmetry P and extends towards the front end AV for the front supplemental element 6a and towards the rear AR for the rear supplemental element 6b.
Further, the longitudinal arms 60, 61; 62, 63 of each supplemental element 6a, 6b which extend on either side of the plane of symmetry P are connected at one end with a transverse connecting part 70, 71.
Thus, the front supplemental element 6a is such that the back ends of the longitudinal arm 60, 61 are connected by the transverse connecting part 70. Analogously, the ends of each longitudinal arm 62, 63 of the rear supplemental element 6b are connected by the transverse connecting part 71.
It is to be understood that in the illustrated embodiment, each supplemental element has the shape of a “U”, opening towards the front AV for the front supplemental element 6a and opening towards the rear for the rear AR supplemental element 6b. It is also understood that each transverse connecting part 70, 71 includes a connecting part for interconnecting its supplemental element with the platform 3.
As indicated above, the supplemental elements are removably connected with the platform, allowing each supplemental element to be disconnected. That is, the supplemental elements are retained on the platform in a removable way. Thus, the ski and more particularly the platform and the supplemental elements include interconnecting means also called removable connection assembly for allowing the supplemental elements to be connected and disconnected with the platform.
Thus, the removable connecting assembly includes a first means on the supplemental elements which is configured to cooperate with a second, complementary connecting means mounted on the corresponding end of the platform.
In addition, the removable connecting assembly includes an inter-engaging means and a locking and unlocking means.
One will also note that the ski includes a visual indicator for indicating a proper interconnection and locking between the supplemental elements and the platform. This avoids any risk of inopportune decoupling or breakage.
As previously indicated, the front supplemental element 6a extends forward of the platform and includes two longitudinal arms 60, 61 extending toward the front AV. These arms are connected at their back end by the transverse connection part 70. The transverse connecting part includes, in one example, two extending engaging arms or tongues 8a, 8b which are configured to be received in and cooperate with two corresponding receiving slots or channels 9a, 9b in the platform.
Further, the connecting part includes a latch element 10 which is resiliently biased to extend upward by an elastic system, such as its own elasticity, a spring, or the like. The latch includes a projection 11 which cooperates after complete engagement with an aperture 12 defined in the platform 3.
Analogously, the rear supplemental element 6b which extends from the rear of the platform with its two longitudinal arms 62, 63 extending towards the back AR connected by the transverse connecting part 71. The transverse connecting part also includes two extending tongues 8a, 8b which cooperatively engage corresponding slots 9a, 9b in the rear of the platform.
In addition, the connecting part 71 includes a resiliently biased latch element 10 with a projection 11 that cooperates, after complete inter-engagement, with an opening 12 defined in the platform.
Such a connection allows quick and easy mounting and demounting of the supplemental element. In this manner, the supplemental element can be easily changed and replaced with a different supplemental element having different characteristics or another geometry. This makes it possible to obtain a ski having different behavior and functional characteristics.
In accordance with a complementary characteristic, this provides a visualization means or indicator which indicates that the supplemental element has been properly assembly with the platform. In the illustrated embodiment of
According to the embodiment of
Further, in the embodiment of
With reference to
In addition, the width of the longitudinal arms can decrease towards the ends. Thus, the front longitudinal arms 60, 61 can decrease in width towards the front and the width of the rear longitudinal arms 62, 63 can decrease towards the rear. Also, the platform 3 can be affixed to the base plate 2 in various ways, such as with screws or the like. The supplement elements 6a, 6b compress with inflexion of the ski during use, but return to their original shape and position with a dynamic recall of the base plate 2.
The longitudinal arms of the supplemental elements allow an increased pressure to be applied by the user directly in a support free zone and increase the bite of the edges. This facilitates biting of the edges at the start of a turn. Further, the arms provide a simple and effective means for adjusting the dynamic recall of the base plate towards its home position.
Of course, the invention is not limited to the embodiments described and illustrated in these examples, but can include all technical equivalents and their combinations.
It will be understood that the platform 3 which, in the illustrated embodiment, extends over a length sufficient to receive the bindings for the ski boot could also include two related parts such as a forward part and a rear part.
It will be added that the longitudinal arms of the supplemental elements can include a basic structure 600 which is supplemented by a reinforcing element 601. The reinforcing element is configured to be received in each arm to alter its functional characteristics, particularly its inflexion. The reinforcement element 601 could be mounted in a recess in the lower part of each corresponding arm as illustrated in
The reinforcement elements 601, for example, are disposed under the arms of the supplemental elements and are retained in a movable way such that the reinforcement elements can be replaced and reassembled using reinforcement elements with different characteristics. In this way, changing the reinforcement elements can be used to modify the characteristics of the arms 61, 62; 63, 64 of the supplemental elements 6a, 6b and thus modify the behavior of the ski.
The skis can be sold with a family of reinforcement elements with different characteristics. The elements with different characteristics can, for example, be color-coded to represent the various characteristics. The reinforcement elements 601, in one example, are flat plates or profiles made of metal or plastic. The characteristics, such as the inflexion, should remain relatively stable with use and over time.
The invention has been described with reference to the preferred embodiment. Modifications and alterations may occur to others upon reading and understanding the preceding detailed description. It is intended that the invention be construed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
