Description

  The present invention relates mainly to a sled for on-the-snow glare integrally formed of a plastic material or the like used by children as a play on snow.

  Conventionally, as an on-snow gliding sled mainly used by children for playing on the snow by integrally forming them with a plastic material or the like, a curved edge sled disclosed in Patent Document 1 is known.

  The sled of the edge of the curve described in Patent Document 1 aims to solve the problem of the conventional sled that can only proceed straight, specifically, the bottom surface (bottom surface) of the sled A part of the front side of the downwardly protruding straight edge provided on the surface of the curved line is formed at the edge of the curve.

Japanese Utility Model Application Publication No. 3-7865

  However, the above-described conventional sledding on snow (sled of the edge of a curve) has the following problems.

  First, the conventional sled is an improvement of the downwardly convexly formed edge. That is, since the original edge is provided for the purpose of securing the straightness, a part of this edge is curved to add bendability. Therefore, from the viewpoint of securing the straightness, at least a part of the edge is sacrificed, and since only a part of the edge is used, good steering performance also from the viewpoint of securing the bendability (steerability) For example, it is difficult to obtain sufficient functions for both the straight driving function and the steering function.

  Second, in addition to the inherent straightness, the improvement is the addition of a steering function as an added value, so it is not necessarily sufficient from the viewpoint of multi-functionalization of the sled. That is, by adding multifunctionality, the diversity of sled play is further enhanced, and there is room for further improvement from the viewpoint of further enhancing the enjoyment of sled play and the safety.

  This invention aims at provision of the sled for on-the-snow gliding which solved the subject which exists in such a background art.

  In order to solve the above-mentioned problem, the present invention solves the above-mentioned problem, a sliding sole plate 2 having a lower surface 2d capable of sliding on the snow surface S and an upper surface 2u on which a user H can sit, and the left end side of the sliding sole plate 2 A left side plate portion 3 standing up from 2d, a right side plate portion 4 standing up from the right end side 2q of the sliding bottom plate portion 2, and an inclined surface portion 5s extending forward and upward from the sliding bottom plate portion 2 When constructing the on-snow gliding sled 1 integrally formed with the front side plate portion 5 and the rear side plate portion 6 standing upward from the rear end of the slide bottom plate portion 2, at least a part of the lower surface portion 2d The smooth bottom plate portion 2 formed by the curved surface 14 in which the intermediate portion 2 dm in the direction Fy curves downward, and one or more positions of the lower surface portion 2 d in the smooth bottom plate portion 2 linearly in the front-rear direction Fy The straight guide portions 13 and 13 by the formed ridges and the sliding bottom plate portion 2 The left steering edge 11 in which the middle portions 2pm and 2qm of the left end side 2p and the right end side 2q are curved inward in the lateral direction Fx and the rear side radius of curvature Rr is smaller than the front side radius of curvature Rf The right steering end 12 and the rear portion 2dr of the lower surface portion 2d of the slide bottom portion 6 at the rear with respect to the rear ends of the rectilinear guide portions 13 and 13, the left steering end 11 and the right steering end 12; The present invention is characterized in that brake portions 15 each having a convex streak formed with the longitudinal direction in the left-right direction Fx are provided at one or more separated positions.

  According to the on-snow gliding sled 1 of the present invention having such a configuration, the following remarkable effects can be obtained.

  (1) A part or all of the left end side 2p in the slip bottom plate portion 2 is formed as the left steering end side 11 of which the middle portion 2pm is curved inward in the left-right direction Fx, and a part of the right end side 2q or Since all the intermediate portions 2qm are formed as the right steering end side 12 having a shape curved inward in the left-right direction Fx, during straight running, smooth straight running can be performed without sacrificing straightness and steering Sometimes, the steering function by the left steering end 11 or the right steering end 12 can smoothly change the direction to the left or right, etc., sufficiently securing the functions of both the rectilinear function and the steering function. Straightness and steering can be obtained.

  (2) In forming the left steering end 11 and the right steering end 12 in the slip bottom plate portion 2, the curvature radius Rr on the rear side is smaller than the curvature radius Rf on the front side, so the user H can The steering degree (turning radius) can be changed by changing the position where the weight is applied. That is, if the weight is placed closer to the front, the operation degree can be made gentle (the steering radius can be made larger), and if the weight is placed to the rear, the operation degree can be made tight (the steering radius can be made smaller). In addition, even when steering is performed during normal steering, that is, without moving the weight back and forth, it is possible to prevent abrupt rotation and gradually tighten the rotation angle, etc. Can be secured. As a result, stability and further safety can be further enhanced, and the pleasure during sliding can be further enhanced.

  (3) Since the rectilinear guide portions 13 and 13 with the convex streaks are linearly formed in the front-rear direction Fy at one or two or more positions of the lower surface portion 2 d in the slip bottom plate portion 2 At the time of straight running where the lower surface portion 2d of the bottom plate portion 2 is parallel, the straight running guide function in the straight running guides 13, 13 can be maximized while avoiding the influence of the left steering end 11 and the right steering end 12. Thereby, highly stable straightness can be secured. In addition, since at least a part of the lower surface 2d of the sliding bottom plate 2 is formed by the curved surface 14 in which the middle portion 2dm in the front-rear direction Fy curves downward, the contact area of the lower surface 2d with respect to the snow surface S and The contact resistance can be effectively reduced. This makes it possible to secure good sliding performance.

  (4) The rear portion 2dr of the lower surface portion 2d of the sliding bottom plate portion 6, which is spaced apart rearwardly with respect to the rear ends of the rectilinear guide portions 13, 13, the left steering end 11 and the right steering end 12 The brakes 15 with ridges are formed at two or more positions with the longitudinal direction as the horizontal direction Fx, so if the speed at the time of sliding becomes too fast or if it is desired to stop, the user H is behind The brakes 15 can be pressed against the snow surface S by putting weight on them. As a result, it is possible to provide a braking function for braking the sliding of the snow-on-sliding sled 1 and to further enhance multifunctionality such as being able to provide a stop function. In particular, by combining the braking function and the stopping function with the above-mentioned good straight ahead function and steering function, it is possible to configure the solitary on-snow sled 1 as it is equipped with all the steering functions at the time of sliding . Thus, the variety of sled play can be further enhanced, and the fun and safety of sled play can be further enhanced.

  Next, preferred embodiments according to the present invention will be listed and described in detail based on the drawings.

  First, the configuration of the on-snow sled 1 according to the present embodiment will be described with reference to FIGS. 1 to 6.

  First, the basic configuration of the snow sled 1 according to the present embodiment will be described with reference to FIGS. 1 and 4. The snow-sliding sled 1 comprises a slip bottom plate portion 2, a left side plate portion 3 erected from the left end side 2p of the slip bottom plate portion 2, a right side plate portion 4 erected from the right end side 2 q of the slip bottom plate portion 2, and a slip bottom plate portion 2 A front side plate portion 5 extending forward from the rear side plate portion 6 and a rear side plate portion 6 rising upward from the rear end of the sliding bottom plate portion 2 are integrally formed of a plastic material (synthetic resin material). Therefore, the front and rear end sides of the left side plate portion 3 are continuous with the left end sides of the front side plate portion 5 and the rear side plate portion 6, and the front and rear end sides of the right side plate portion 4 are the front side plate portion 5 and the rear side plate portion 6. It is continuous with the right side of.

  In FIG. 4, reference numerals 21 and 21 denote handle portions provided at an intermediate portion in the front-rear direction Fy on the inner surfaces of the left side plate portion 3 and the right side plate portion 4. The user H can support the operability with respect to the snow-on-sliding sled 1 by the user H by holding the handle portions 21 and 21 by hand at the time of sliding, and at the time of straight running when using the snow-on-sliding sled 1, steering This can contribute to ensuring the stability and safety of the user H himself at the time of braking and at the time of braking and the like.

  Next, the detail of each part which comprises the sled 1 for a skid on snow is concretely demonstrated with reference to FIGS. 1-7.

  The sliding bottom plate 2 has a lower surface 2d capable of sliding on the snow surface S and an upper surface 2u on which the user H can be placed. The slide bottom plate portion 2 is formed in a single plate shape, and in particular, the lower surface portion 2 d of the slide bottom plate portion 2 is substantially parallel to the horizontal line Lh in the left-right direction Fx as shown in FIG. In the front-rear direction Fy, as shown in FIG. 3, the intermediate portion 2 dm is formed on the curved surface 14 that curves downward. In this case, although it is desirable to apply the curved surface 14 to the whole of the lower surface part 2d, the case where it is applied to a part is not excluded. By forming the lower surface portion 2 d in this manner, the contact area of the lower surface portion 2 d with respect to the snow surface S and the contact resistance at the time of sliding can be effectively reduced, so that good sliding performance can be ensured.

  The left end side 2 p of the slide bottom plate portion 2 forms the middle portion 2 pm as the left steering end side 11, and the right end side 2 q forms the middle portion 2 qm as the right steering end side 12. In this case, the left steering end 11 is formed such that the intermediate portion 2pm is curved in the left and right direction Fx, and the right steering end 12 is formed such that the intermediate portion 2qm is curved in the left and right direction Fx, , And a left-right symmetrical shape with respect to the left steering end 11. The left steering end 11 and the right steering end 12 may be applied to all or part of the left end 2p and the right end 2q. In the illustrated case, as described later, in order to form the brake unit 15 at the position of the rear portion 2dr in the lower surface portion 2d, the left steering edge 11 and the right steering edge 12 are applied to the range excluding the rear portion 2dr. .

  In particular, as shown in FIG. 6, the left steering end 11 and the right steering end 12 are formed such that the radius of curvature Rr on the rear side is smaller than the radius of curvature Rf on the front side. Therefore, the size of the cutting angle Qf with respect to the slip bottom plate 2 at the front end of the left steering end 11 with respect to the straight line Ls in the front-rear direction Fy It becomes smaller than the included angle Qr. If the left steering end 11 and the right steering end 12 are formed under such conditions, the steering degree (turning radius) can be changed by changing the position where the user H applies weight in the front-rear direction Fy. . That is, if the weight is placed closer to the front, the operation degree can be made gentle (the steering radius can be made larger), and if the weight is placed to the rear, the operation degree can be made tight (the steering radius can be made smaller). In addition, even when steering is performed during normal steering, that is, without moving the weight back and forth, it is possible to prevent abrupt rotation and gradually tighten the rotation angle, etc. Can be secured. As a result, stability and further safety can be further enhanced, and the pleasure during sliding can be further enhanced.

  Further, at the two positions of the lower surface portion 2d of the slide bottom portion 2 which are separated to the left and right, rectilinear guide portions 13, 13 are formed linearly in the front-rear direction Fy. The cross-sectional shape of the rectilinear guide portions 13 and 13 can be formed in a U-shape as a standard shape as shown in FIG. 5 (a). In the case of the illustrated rectilinear guide portions 13 and 13, the height projecting from the lower surface portion 2d is approximately 1 cm. The cross-sectional shape of the rectilinear guide portions 13 and 13 is not limited to a specific shape, and may be, for example, a V shape (inverted trapezoidal shape) as shown as a modified example in FIG. And various cross-sectional shapes are applicable. Therefore, if such straight guide portions 13 and 13 are provided, the left steered end 11 and the right steered end 12 of the straight steering slide in which the lower surface portion 2d of the slide bottom plate 2 is parallel to the snow surface S Since the rectilinear guide function of the rectilinear guides 13 and 13 can be maximized while avoiding the influence, it is possible to secure highly stable rectilinearity.

  In addition, as shown in FIG. 1 and FIG. 3, at the position of the rear portion 2dr in the lower surface portion 2d of the smooth bottom plate portion 6, the brake portion 15 with a convex stripe is formed in the longitudinal direction Fx. As described above, the lower surface portion 2d of the smooth bottom plate portion 6 is formed as the curved surface 14 in which the intermediate portion 2dm curves downward, so the rear portion 2dr of the lower surface portion 2d provided with the brake portion 15 is shown in FIG. As described above, the height increases toward the rear end side, so that by selecting the position where the brake portion 15 is disposed, the brake portion 15 can be floated upward with respect to the snow surface S during normal sliding. That is, during normal sliding, it is possible to slide without being affected by the brake unit 15.

  Further, the form of the brake portion 15 is not limited to a specific form, but basically, it can be formed by a single convex line having a linear shape as shown in FIG. 1. The cross-sectional shape of the brake portion 15 is formed in the same manner as the cross-sectional shape of the straight advance guide portion 13 described above, but the protruding height from the rear portion 2dr can be arbitrarily selected in the range of 1 to 2 cm, for example. In order to enhance the ability, the protrusion height may be increased.

  In addition, the example of a change of the brake part 15 is shown in FIG. Fig.7 (a) shows the example of the brake part 15 formed by the convex line of a triangular wave shape. On the other hand, in FIG. 7B, the brakes 15, 15 are respectively provided at two positions separated in the front-rear direction Fy, and the forms of the respective brakes 15, 15 are made different. That is, the example which provided the brake part 15 formed by the linear form in the front side and provided the brake part 15 of the triangular wave shape in the rear side is shown. The combination and form in this case can be selected arbitrarily. In the case of FIG. 7 (b), since the positions in the front-rear direction Fy are different, the heights are also different, and the weight of the user H during sliding of the on-snow gliding sled 1 ie, the on-snow gliding sled 1 If the inclination angle is different, a weak braking mode using one brake unit 15 and a forced movement mode of simultaneous use by both brake units 15 can be used properly.

  Therefore, if such a brake unit 15 is provided, if the speed at the time of sliding becomes too fast or if it is desired to stop, the user H puts weight on the rear side, thereby snowing the brake unit 15. Since it is possible to press against the surface S, it is possible to have a braking function to brake the sliding of the snow sled 1 and to be able to have a stopping function to further enhance multifunctionality. be able to. In particular, by combining the braking function and the stopping function with the above-mentioned good straight ahead function and steering function, it is possible to configure the solitary on-snow sled 1 as it is equipped with all the steering functions at the time of sliding . As a result, there is an advantage that the diversity of sled play can be further enhanced, and the fun and safety of sled play can be further enhanced.

  On the other hand, as shown in FIG. 2, the left side plate portion 3 is erected in an inclined state from the left end side 2 p of the sliding bottom plate portion 2, and the right side plate portion 4 is erected in an inclined state from the right end side 2 q of the sliding bottom plate portion 2. Let it form. In this case, the space between the left side plate portion 3 and the right side plate portion 4 is inclined in an upward spread so that the upper side becomes wider. On the other hand, as shown in FIG. 3, the front side plate portion 5 is provided with an inclined surface portion 5 s extending forward and upward from the front end side of the sliding bottom plate portion 2. In this case, since the front plate portion 5 and the slide bottom plate portion 2 form an integral continuous shape, a specific boundary is not specified, but at least a part of the front plate portion 5 has the above-mentioned front upper side An extended inclined surface 5s is provided. Therefore, the inclined surface 5s may be applied to the entire front plate 5. In addition, since the straight advance guides 13 and 13 described above are provided in the slide bottom plate 2, the front plate 5 is at least a portion excluding this range. Further, as shown in FIG. 3, the rear side plate portion 6 is formed so as to be substantially vertically erected upward from the rear end of the sliding bottom plate portion 2.

  Next, a method of use including the function of each part of the snow sled 1 according to the present embodiment will be described with reference to FIGS. 8 to 10 with reference to the respective drawings.

  The snow sled 1 is mainly used by children. In use, first, as shown in FIG. 8, the sled for on-snow gliding 1 is placed on the inclined snow surface S, and the user (child) H is placed on the upper surface 2 u of the sliding bottom plate 2. You can sit back and forth. Then, in this state, if the snow-on-the-sliding sled 1 is pushed forward, it is possible to slide in the straight direction Df. At this time, since the user H can hold the handle portions 21 and 21 by hand, the user H can support the operability with respect to the snow-on-the-sliding sled 1 and at the time of using the snow-on-the-sliding sled 1 This can contribute to ensuring the stability and safety of the user H himself when traveling straight ahead, steering and braking.

  At the time of sliding, the lower surface portion 2d of the sliding bottom plate portion 2 is in a parallel state, ie, in surface contact with the snow surface S, as shown in FIG. Therefore, the straight guide portions 13 and 13 are hardly at right angles to the snow surface S, and the straightness in the sliding direction is sufficiently ensured, and the left steering end 11 and the right steering end 12 are on the snow surface S. Because of the parallel direction, the influence of the left steering end 11 and the right steering end 12 is virtually avoided. That is, while the straight advance guide function in the straight advance guides 13, 13 is exhibited to the maximum, high straightness with high stability is secured.

  On the other hand, it is assumed that the direction is changed to the left direction from the sliding in the straight direction Df. In this case, the user H may tilt the snow-sliding sled 1 to the left as shown in FIG. 9 by shifting (transferring) his or her weight to the left. As a result, the left steering end 11 facing parallel to the snow surface S bites in at a predetermined angle with respect to the snow surface S, and at the same time goes straight on as the basic action. The guide portions 13 and 13 float on the snow surface S. In this case, since the left steering end 11 has a curved shape in which the intermediate portion 2pm is recessed in the left-right direction Fx, that is, rightward, the snow sled 1 has an arrow Dp so as to follow the curved shape. Change direction to direction.

  Under the present circumstances, since the left steering end 11 is formed so that the curvature radius Rr of a rear side is smaller than the curvature radius Rf of a front side, a sudden rotation is prevented and a rotation angle becomes tight gradually etc. Smoothness is ensured, stability and safety are enhanced. In addition, if the user H applies weight on the left side and weight on the front side at the same time, the operation degree can be moderated (the steering radius can be increased) and weight can be applied to the left side at the same time. If weight is placed on the other side, the maneuvering degree can be made tight (steering radius can be reduced), etc., so that the maneuvering technique for the on-snow gliding sled 1 can be exhibited, and the pleasure at the time of gliding can be further enhanced.

  Although the case of changing the direction to the left has been described, also in the case of changing the direction to the right, the direction in which weight is applied may be changed to the right, and similarly to the case of changing the direction to the left, the direction to the right It can do the conversion.

  On the other hand, it is assumed that the vehicle is braked from the time of sliding and then stopped. In this case, as shown in FIG. 10, the user H may lean backward on the snow-on-sliding sled 1 and put weight on the rear side at the time of sliding. As a result, the sled for snow sliding 1 leans backward, and the brakes 15 ... which were away from the snow surface S, as shown in the figure, are intruded in the snow surface S, and the resistance in the arrow Dr direction is sliding. While being able to brake the sliding of the snow-on-sliding sled 1 because it is added to the snow-on-sliding sled 1, the sliding can finally be stopped by increasing the degree of weight application.

  Thus, according to the sled for snowfall 1 according to the present embodiment, as a basic configuration, a part or all of the left end side 2p in the sliding bottom plate portion 2 is moved inward in the left-right direction Fx with the intermediate portion 2pm. Since it is formed as the left steering end side 11 of the curved shape, and part or all of the right end side 2q is formed as the right steering end side 12 of the shape where the intermediate portion 2qm is curved inward in the left-right direction Fx, Smooth straight running without sacrificing straightness, and at the time of steering, the steering function by the left steering end 11 or the right steering end 12 changes the direction smoothly to the left or right. Thus, the functions of both the straight movement function and the steering function can be sufficiently ensured, and good straightness and steering performance can be obtained.

  The preferred embodiment has been described above in detail, but the present invention is not limited to such an embodiment, and the details, configurations, materials, quantities, numerical values, etc. of the details do not deviate from the scope of the present invention. The range can be changed, added, or deleted arbitrarily.

  For example, although the case where the sled for on-the-snow gliding is integrally formed of a plastic material is shown, any other material such as a metal material or a wood material can be used. In addition to integral molding, a configuration in which a plurality of members (parts) are combined may be used. On the other hand, although the case where the rectilinear guide portions 13 and 13 are formed at two places of the lower surface part 2 d in the slide bottom plate part 2 is illustrated, the position to be formed may be one place or three or more places. It is also good. Furthermore, although the smooth bottom plate part 2 showed the case where the lower surface part 2d was formed in the curved surface 14 which the intermediate part 2dm of the front-back direction Fy curves below, the curved surface 14 has a flat surface in part, etc. The present invention may be applied to only a part of the lower surface 2d.
