Slide play apparatus and wing plate

Technical field

The present invention relates to a kind ofly can on snowfield, turf, slide the slide play apparatus of usefulness.

Background technology

Slide play apparatus by glider's deadweight is slided on the slope for example has the skis that slides usefulness on snowfield.The skis of Cai Yonging in the past roughly is an oblong plate and constitutes from the plane by having formed, and is planing surface below the plate, is the face of taking for the glider of taking above the plate.The glider is mobile this plate that is delivered to of center of gravity, the action of turning round about can carrying out (seeing that the Japan Patent spy opens the 2004-160095 communique).

But nearly all skis all is made of a plate, owing to roughly be Long Circle from the plane, so, the thoughts and feelings that the glider is subjected to from snowfield, slide sensation etc. and do not have marked difference.In addition, owing to only clip a plate between snow face and glider's the pin, so glider's pin is subjected to from the impact of snowfield very big.

Summary of the invention

The present invention makes in order to address these problems, and slide play apparatus of the present invention is not limited to slide on snowfield, also can slide on the slope of turf, sand face etc.Problem of the present invention provide a kind of can alleviate glider's body burden and can obtain with in the past slide that the recreation apparatus is different to be slided the slide play apparatus of sensation and can relax the suitable wing plates that impact.

Slide play apparatus of the present invention is characterized in that, is made of guide plate, upper plate, a plate and tailgate, roughly is tubular, and this guide plate slides on the slope, in its outboard end the 1st blade is arranged; This upper plate is positioned at the top of this guide plate; This plate connects an end of guide plate and an end of upper plate; This tailgate connects the other end of guide plate and the other end of upper plate.

According to this invention, owing to form roughly slightly tubular, and is connected guide plate and the upper plate that is positioned at above this guide plate with tailgate with a plate, so a plate and tailgate play cushioning effect, can relax the impact that glider's pin is subjected to.Because the impact that glider's pin is subjected to is relaxed, so, can obtain and differently in the past slide sensation, feel.

In addition, among the present invention, the 1st lateral bending pars convoluta also can be arranged in outboard end.

＜running-active status 〉

Below, the running-active status of slide play apparatus 1 is described.In the explanation of the 1st embodiment, be the situation that explanation is slided on snowfield (ski slope).

Slide play apparatus 1 as shown in Figure 1, is being fixed pin fixator T up on the plate 6, the pin of glider P is fixed on this pin fixator T, and by the deadweight of glider P, (planing surface) slides on planing surface towards the slope.In the 1st embodiment, left foot is towards the direct of travel of planing surface.

State when vertically acting on the body weight of glider P on the guide plate 7 is during as inactive state, said in the explanation of the 1st embodiment " compression ", be meant the center of gravity because glider P moves, upper plate 6 shortens than inactive state with the distance (distance of fixed part and contact site) of guide plate 7.In addition, said open to the outside world is meant that the upper plate 6 and the distance (distance of fixed part and contact site) of guide plate 7 increase than inactive state.

(during straight sliding)

As shown in figure 12, the body weight of glider P vertically acts on the guide plate 7, can slide as the crow flies.That is, when the body weight of glider P vertically acts on the guide plate 7, because the 2nd blade 45a, the 45c that are provided on the wing plate 3 do not contact planing surface S, so the whole following of guide plate 7 contacts with planing surface substantially, can slide as the crow flies.

In addition, as shown in figure 13, when glider P when direct of travel moves to left foot to centre of body weight, be compressed between the upper plate 6 of left foot side and the guide plate 7 (arrow 55), simultaneously because the reaction of wing plate 3, open (arrow 56) can carry out center of gravity reposefully and move between the upper plate 6 of right crus of diaphragm side and the guide plate 7.

(when turning round action)

The slide play apparatus 1 of the 1st embodiment as shown in figure 14, along with the glider P center of gravity of moving, makes the 1st blade 14 or the 2nd blade 45 contact (planing surface of nipping) with planing surface S, the action of just can turning round.

Here, illustrate glider P with respect to direct of travel towards the situation (arrow 62 directions among Figure 16) of turning right when curved.

When glider P makes centre of body weight move to left foot front side (toe side), shown in Figure 14 (a), be compressed between upper plate 6 that left foot front side (toe side) is located and the guide plate 7 (arrow 57), simultaneously, upper plate 6 is opened (arrow 58) with the rear side (heel side) of guide plate 7, slide play apparatus 1 is angle of inclination γ integrally, and the 1st blade 14a bites planing surface S.

At this moment, because the protuberance 43a of upper strata wing plate 3a released towards the center of gravity moving direction, so the 2nd blade 45a planing surface S that nips can carry out turning round more rapidly.

Promptly, when glider P makes centre of body weight move to left foot front side (toe side), be compressed between left foot front side fixed part 31 and the left foot front side contact site 32, simultaneously, as its reaction, open (see figure 6) between right crus of diaphragm rear side fixed part 34 and the right crus of diaphragm rear side contact site 35.At this moment, though the left foot front side fixed part 31 of upper strata wing plate 3a and right crus of diaphragm rear side fixed part 34 be fixed on upper plate 6 below, but, because 35 of left foot front side contact site 32 and right crus of diaphragm rear side contact sites contact with the top of guide plate 7, so protuberance 43a moves along with the center of gravity of glider P and slides.

As shown in figure 15, when being compressed between the left foot front side fixed part 31 of upper strata wing plate 3a and left foot front side contact site 32 (see figure 6)s, upper strata wing plate 3a rubs the torsion on the La of portion and rotates towards arrow 60 directions by being located to wipe.Upper strata wing plate 3a is owing to fixing two ends with left foot front side fixed part 31 and right crus of diaphragm rear side fixed part 34, so slip on guide plate 7 makes protuberance 43a by towards center of gravity moving direction release (arrow 61).Like this, shown in Figure 14 (a), has the 2nd blade 45a planing surface S that nips on the protuberance 43a.

At this moment, the upper strata wing plate 3a at central portion C place, the wing plate 3b of lower floor and

support

5,5 slide towards rear side (heel side).That is, in inactive state, as shown in Figure 9, and each center of upper strata wing plate 3a, the wing plate 3b of lower floor and

support

5,5, C roughly overlaps with central portion.But when glider P moves centre of body weight towards left foot front side (toe side) when mobile, upper strata wing plate 3a, the wing plate 3b of lower floor and

support

5,5 are released ground towards heel side and are slided.

As shown in figure 16, when centre of body weight is moved to left foot front side (toe side), because load also affacts the toe side of right crus of diaphragm, so, be compressed (arrow 59) between right crus of diaphragm front side fixed part 40 and the right crus of diaphragm front side contact site 41.Because the body weight of glider P acts on the left foot front side eventually, so, between left foot front side fixed part 31 and the left foot front side contact site 32 than being compressed more between right crus of diaphragm front side fixed part 40 and the right crus of diaphragm front side contact site 41.Protuberance 43d is by the effect roughly same with above-mentioned 43a, slides along with moving of glider P, simultaneously, released towards planing surface S, so, the 2nd blade 45d planing surface S (arrow 63) that nips.

As mentioned above, be provided in the 2nd blade 45a of protuberance 43a, the 2nd blade 45d that is provided in the 1st blade 14a on the guide plate 7 and is provided in protuberance 43d, bite planing surface.In addition, on

protuberance

43a, 43d with the

2nd blade
