Bicycle for use on snow

A snow bike has a frame which can be either a custom frame or an existing bicycle frame. A pair of footrests consisting of two rods extending perpendicularly from the frame at a location usually set for the pedal means of a bicycle provides a user with a way of resting his feet while using the snow bike.

FIELD OF THE INVENTION

The present invention relates generally to recreational devices but more particularly to a recreational devices for use on slopes consisting of a bicycle frame having each of its wheel replaced by a snow board like device and used on ski slopes.

BACKGROUND OF THE INVENTION

1. Prior Art Capability and Motivations, as Helping to Show Patentability Here

Even in hindsight consideration of the present invention to determine its inventive and novel nature, it is not only conceded but emphasized that the prior art had many details usable in this invention, but only if the prior art had had the guidance of the present invention, details of both capability and motivation.

That is, it is emphasized that the prior art had/or knew several particulars which individually and accumulatively show the non-obviousness of this combination invention. E.g.,a) The cost of the materials are relatively low and do not have a profound impact on price to the point of offsetting the benefits of this novel product;b) The nature of an invention as being a “novel combination”, in spite of existence of details separately, is especially significant here where the novelty is of the plurality of concepts, i.e., the use of an existing bicycle frame and the use of an existing snowboard;c) The addition of providing a stopper and double spring system to limit rotational mobility of the front part of the snowboard in addition to keeping it level especially when in mid-air and a stabilizer on the rear snowboard to eliminate torsion;d) The matter of particular cost-factors, in a detailed form which would surely convey the realization of the huge cost benefits involved in manufacturing such a device;e) The cost-factors involved in the maintenance repair etc since the parts are readily available hardware components;f) The ease of tooling for the present invention has surely given manufacturers ample incentive to have made modifications for commercial competitiveness in a competitive industry, if the concepts had been obvious;g) The prior art has always had sufficient skill to make many types of the stuff we're talking about, more than ample skill to have achieved the present invention, but only if the concepts and their combinations had been conceived;h) Substantially all of the operational characteristics and advantages of details of the present invention, when considered separately from one another and when considered separately from the present invention's details and accomplishment of the details, are within the skill of persons of various arts, but only when considered away from the integrated and novel combination of concepts which by their cooperative combination achieve this advantageous invention;i) The details of the present invention, when considered solely from the standpoint of construction, are exceedingly simple, basically a bicycle frame and a snowboard cut in two halves and the matter of simplicity of construction has long been recognized as indicative of inventive creativity;j) Similarly, and a long-recognized indication of inventiveness of a novel combination, is the realistic principle that a person of ordinary skill in the art, as illustrated with respect to the claimed combination as differing in the stated respects from the prior art both as to construction and concept, is presumed to be one who thinks along the line of conventional wisdom in the art and is not one who undertakes to innovate; andk) The predictable benefits from a novel way of making a snow bike having the features of this invention would seem sufficiently high that others would have been working on this type of product, but only if the concepts which it presents had been conceived.

Accordingly, although the prior art has had capability and motivation, amply sufficient to presumably give incentive to the development a snow bike according to the present invention, the fact remains that this invention awaited the creativity and inventive discovery of the present inventor. In spite of ample motivation, the prior art did not suggest this invention.

2. Prior Art as Particular Instances of Failure to Provide this Novel Product and Installation Method

In view of the general economic advantages, of the present invention as an improved embodiment of the prior art, it may be difficult to realize that the prior art has not conceived of the combination purpose and achievement of the present invention, even though the need for it is a known requested commodity for people nowadays who want to have a way of leveraging the use of their bicycle by adapting it to a winter activity. Surely the need for a safe and secure snow bike being able to reproduce on snow the type of acrobatics feasible in a BMX bike has been known for decades and the technology to achieve such results has been known for years and that the various combination provided in this invention would have been desired and attempted long ago, but only if its factors and combination-nature had been obvious.

Other considerations, as herein mentioned, when realistically evaluated show the inventive nature of the present invention, a change in concept which the prior patent and other prior art did not achieve.

SUMMARY OF THE PRIOR ART'S LACK OF SUGGESTIONS OF THE CONCEPTS OF THE INVENTION'S COMBINATION

And the existence of such prior art knowledge and related ideas embodying such various features is not only conceded, it is emphasized; for as to the novelty here of the combination, of the invention as considered as a whole, a contrast to the prior art helps also to remind of needed improvement, and the advantages and the inventive significance of the present concepts. Thus, as shown herein as a contrast to all the prior art, the inventive significance of the present concepts as a combination is emphasized, and the nature of the concepts and their results can perhaps be easier seen as an invention.

Although varieties of prior art are conceded, and ample motivation is shown, and full capability in the prior art is conceded, no prior art shows or suggests details of the overall combination of the present invention, as is the proper and accepted way of considering the inventiveness nature of the concepts.

That is, although the prior art may show an approach to the overall invention, it is determinatively significant that none of the prior art shows the novel and advantageous concepts in combination, which provides the merits of this invention, even though certain details are shown separately from this accomplishment as a combination.

And the prior art's lack of an invention of a the use of an existing bicycle frame and the use of an existing snowboard;

The addition of providing a stopper and double spring system to limit rotational mobility of the front part of the snowboard in addition to keeping it level especially when in mid-air and a stabilizer on the rear snowboard to eliminate torsion and other advantages of the present invention, which are goals only approached by the prior art, must be recognized as being a long-felt need now fulfilled.

Accordingly, the various concepts and components are conceded and emphasized to have been widely known in the prior art as to various installations; nevertheless, the prior art not having had the particular combination of concepts and details as here presented and shown in novel combination different from the prior art and its suggestions, even only a fair amount of realistic humility, to avoid consideration of this invention improperly by hindsight, requires the concepts and achievements here to be realistically viewed as a novel combination, inventive in nature. And especially is this a realistic consideration when viewed from the position of a person of ordinary skill in this art at the time of this invention, and without trying to reconstruct this invention from the prior art without use of hindsight toward particulars not suggested by the prior art.

FEATURES AND ADVANTAGES OF THE INVENTION

It is a main advantage of this invention to provide for a bicycle frame having snowboard like implements to replace wheels and footrests to replace pedals.

The use of an existing bicycle frame and the use of an existing snowboard;

The addition of providing a stopper and double spring system to limit rotational mobility of the front part of the snowboard;

A stabilizer on the rear snowboard to eliminate torsion.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known devices now present in the prior art, the present invention, which will be described subsequently in greater detail, is to provide objects and advantages which are:

To provide for a snow bike that uses of an existing bicycle frame and the use of an existing snowboard.

The addition of providing a stopper and double spring system to limit rotational mobility of the front part of the snowboard.

A stabilizer on the rear snowboard to eliminate torsion.

To attain these ends, the present invention generally comprises a pair of footrests consisting of two rods extending perpendicularly from said frame at a location usually set for the pedal means of a bicycle.

Front and rear snowboard like implements are each mechanically attached to said frame each by way of mechanical fasteners linking said frame to a bracket.

Said brackets itself being fixedly attached to said snowboard like implements.

The front snowboard implement is mechanically fastened to a fork on the frame by way of a front bracket that is itself mechanically fastened to the front snowboard like implement and rotationally attached to a fork.

The front snowboard like implement has rotational capability along a horizontal axis which is limited by way of a blocker and is biased, by way of a double spring in such a way so as to maintain the front snowboard like implement level.

The rear snowboard like implement is mechanically fastened to the rear of the frame where a rear wheel is usually installed, by way of a rear bracket that is itself mechanically fastened to the rear snowboard like implement.

The front part of the rear snowboard like implement has an anti torsion device which is made out of two distinct and separate parts: a bottom plate, which is fixedly attached to the rear snowboard like implement, and an abutment part which is fixedly attached to a wheel crank mount of the bicycle frame.

The bottom plate has a nut protruding perpendicularly therefrom and which sits within the abutment part by way of an opening.

Both front and rear snowboard like implement have guiding edges to improve the handling of the snow bike.

The footrests consist of a threaded rod passing through the wheel crank mount and two end caps.

The blocker consists in an ablate piece with a hole used when bolting to the fork at the same time as the front bracket is installed and can be adjusted to limit the rotation of the front snowboard like implement to about 50 degrees from the horizontal.

DETAILED DESCRIPTION

A snow bike (10) has a frame (12) which can be either a custom frame or an existing bicycle frame. A pair of footrests (14), consisting of two rods extending perpendicularly from the frame (12) and at a location usually set for the pedal means of a bicycle, provides a user with a way of resting his feet while using the snow bike (10).

Front and rear snowboard like implements (16,18) are each mechanically attached to the frame (12). The front snowboard implement (16) is mechanically fastened to a fork (17) on the frame (12) by way of a front bracket (20) that is itself mechanically fastened to the front snowboard like implement (16) and rotationally attached to the fork (17).

The front snowboard like implement (16) has some measure of rotational capability along a horizontal axis which is limited by way of a blocker (24) and is biased, by way of a double spring (22), in such a way so as to maintain the front snowboard like implement (16) as level as possible.

The rear snowboard like implement (18) is mechanically fastened to the rear of the frame (12) where a rear wheel (not shown) is usually installed, by way of a rear bracket (20′) that is itself mechanically fastened to the rear snowboard like implement (18).

The front part of the rear snowboard like implement (18) has an anti a bottom plate (28), which is fixedly attached to the rear snowboard like implement (18), and an abutment part (30) which is fixedly attached to a wheel crank mount (32) of the bicycle frame (12). The bottom plate has a nut (34) protruding perpendicularly therefrom and which sits within the abutment part (30) by way of an opening (33). This arrangement prevents the rear snowboard like implement (18) from twisting.

Both front and rear snowboard like implement (16,18) have guiding edges (40,40′) to improve the handling of the snow bike (10).

The footrests (14) consist of a threaded rod (36) passing through the wheel crank mount (32) and two end caps (38).

The blocker (24) consists in an ablate piece with a hole (25) used when bolting to the fork (17) at the same time as the front bracket (20) is installed and can be adjusted to limit the rotation of the front snowboard like implement (16) to about 50 degrees from the horizontal.
