Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a snow-type 1lIIJ vehicle. More specifically, the present invention relates to a snow surface type 1lIIJ vehicle, and more particularly, a motor is mounted inside the frame, and a clutch mechanism connected to the four stages of the motor, In a snow surface driving vehicle having a driving means at the bottom of the frame, the driving means is provided with a power transmission means such as a transmission mechanism, and is driven via the above-mentioned ig, dynamic motor power 1 and arresting means, the seat is supported. The support rod and V-rubbing part (handle) are removable or can be stored inside or near the frame, making it possible to climb not only on flat ground covered with snow but also on slopes. As a snow surface drive vehicle, for example, when moving skis from a low area such as the foot of a mountain to a high area where skiing will start, it is necessary to adjust the load position according to the inclination angle of the slope. While shifting, the center of gravity between the snow surface drive vehicle and the rider wearing skis is adjusted appropriately to create the optimal condition for climbing, and it is also possible to freely turn left and right, allowing for efficient and smooth climbing. The object of the present invention is to provide a lightweight and portable snow surface drive 1 that can be used to drive snow surfaces.

``Prior Art'' Conventionally, so-called snowmobiles, which are used to run on flat snowy terrain, are equipped with caterpillars on the bottom of a sled-shaped main body, and run by driving the caterpillars with an arbitrary structure such as a chain. There is something called. However, with the above-mentioned ``7'' train, it is not only possible to go straight on flat ground (but if you try to climb a slope, it will be difficult).

The center of gravity of the upper Jμ itself is near the rear, and
Since a person is driving while sitting and leaning backwards, the center of gravity becomes more difficult to move backwards on a slope, and the center of gravity does not shift □ when climbing on a slope.
・Furthermore, can passengers wear skis while boarding? There was no lift, it was heavy, and there was nothing you could carry with you when skiing down from a high altitude.

``Problems to be Solved by the Invention'' Therefore, when enjoying skiing on a holiday with Ski Maru et al., it takes a long time, for example, an hour, to enjoy skiing downhill from a highland to a lowland for a few minutes to more than ten minutes. , I had to climb higher than lower places and wait my turn to get on the 7th.
I was extremely upset.

Therefore, you can freely climb up the slope even on the 6 slopes where there is no IJ7 structure, you can run on the snow surface without the danger of flipping backwards, and you can slide the handlebars laterally. Turn the town F and R
In addition, the operation part consisting of the support rod and V operation nodle that supports the I-F can be removed or rotated when carrying the product of the present invention on the back with a strap attached or separately carried. There has been a strong desire for the emergence of a lightweight, so-called portable snow surface drive device capable of driving on sloping snow surfaces. - ゛ [Means for determining the problem] In view of the above situation, the present invention has been made to provide a lightweight snow surface drive vehicle that satisfies the conventional demands and is capable of climbing the slopes on any slope. This was the result of repeated trial and error day and night to provide Z), and inside the frame,
A power transmission means is disposed on which a prime mover is mounted, a clutch gear 7 connected to the prime mover, and a transmission 1, etc., and the traveling means is driven by the prime mover via the power transmission means. In the snow surface driving vehicle, the supporting rod and operating part (1 handle) for supporting the seat are provided at the bottom of the frame.
The structure is such that it is removable or can be stored inside or near the frame.

``Function'' Therefore, it is possible to climb freely even on a sloped snow surface where there is no scaffolding, it is possible to drive on the snow surface without the danger of falling over backwards, and the handle can be slid laterally. This is a lightweight, so-called portable snow surface drive vehicle that can travel on sloping snow surfaces, making it possible to turn.

"Example" An embodiment thereof will be described below with reference to the drawings.

(First Embodiment) Is Fig. 1 the first embodiment of the present invention? +M construction perspective view,
Frame 2 configured to form the ridgeline of a rectangular parallelepiped
A prime mover 4 made of, for example, an engine is placed in the internal space of the engine, and the rotational force of the prime mover 4 is transferred from the output shaft (not shown) of the prime mover to a clutch retainer 6 and a gear shift mechanism by a connecting means such as a chain 5. Power transmission means 1 consisting of 8 etc.
The snow surface drive 11 formed by the frame 2 (the endless chain 14 with caterpillars 15 as the traveling means 12 provided at the bottom of the main body 20 is stretched through the frame 2! It is near the groove that transmits the drive to the front main shaft 16 which is the drive side, and furthermore,
The snow surface drive 1it having the above configuration has a portion 22A on the surface of the main body 20 that stands upright by a predetermined height above the upper surface of the frame 2, and the upper part of the upright portion 22A Main body 20. A support rod 22 is bent at a predetermined inclination angle toward the rear of the support rod 22 and has a horizontal portion 22C near the end of the slope portion 22B. That is, an operating portion extending upward, that is, an operating handle 24 is attached to the straight bevel portion 22A, and the support rod extending rearward as described above is provided with an arbitrary resistance force on the support rod. (A pin 27 is inserted into the sliding body 26A, which is bent into a U-shape in cross section, to form a space 26B through which the support rod 22 is inserted, as shown in FIG. As is well known, it is attached by an E-shaped distortion ring or the like, and a seating part 2 made of, for example, leather is mounted on the mounting plate 26C on the upper part of the sliding body 26A.
The seat 26 with 6D fixed to it was attached (1 is the number 1).

Therefore, if we explain the situation when trying to run 77 rows on the snow surface, especially one slope, by using the main brother Meisho of the above-mentioned dry season, as shown in Fig. 2, the flat part Climb the slopes of B and C in order to reach the higher point than A.1
To describe the situation at the time, the passenger M was wearing skis S on his feet. Sit astride the seat 26 and position it at the rear of the elementary and junior high school 8B26E bent upwards on the seat 26 with your crotch, and move the back part of your thigh to the widened part 26F so that your lower back is lifted, and the seat is placed on the support rod. 22, and is positioned in the horizontal portion 22C formed near the end of the support rod. By operating the prime mover control means such as the throttle valve l1i1rtI lever (not shown), the rider can smoothly travel at any speed while sliding on the snow surface as if balancing on skis S attached to his feet, and When pitching on slope B, slightly lift your hips and bend upwards from the seat 26 between your crotches to reach the small middle section 2-G.
Push E forward to move the first part forward and place the seat 2 on the upper part of the slope 1122B of the support rod.
If the rear part of the thigh is brought into contact with the enlarged 11 part 26E of 6, it will become like the 4th part 1, and the point P of the sliding body 2"'6 A will be the support rod 22.
The bottle 2 is attached to the lower rear end of the sliding body 26.
7 and the support rod 22, and the seat is fixed to the inclined part of the support rod by the frictional force between the two. Shift the weight of the rider forward and the weight of the S-plane drive vehicle as shown by the arrow 1. The means 12 is pressed against the slope 7 and the pressed travel-1 stage firmly grips the snow surface. When you climb up the slope smoothly and come to a steeper slope C, move the seat 26 carrying the load further to the right in the same way as described above to position the center of gravity G further forward. Similarly, it is now possible to pitch on steep snow slopes reliably and safely.

Therefore, even on seven surfaces with repeated elevations, the seat 26 can be moved easily and quickly according to the inclination angle.
As shown in Figures 4 and 4, the seat has a shape that protrudes forward, so by slightly lifting your hips and moving the seat forward at the front of your crotch and backward by 11η at the back of your thighs, you can move the seat back by 11η. As shown in FIG. 4, when a load is applied to the seat, the slope 22B of the support rod 22 is exposed to Ill! The contact part of the hanger 26 contacts diagonally, so the point P is strongly supported and pressed against the rod, and if a normal load is applied at that position, the stool will not fall off carelessly ( When it becomes necessary to shift the position of the seat in response to changes in the snow surface conditions, simply move your hips forward or backward so that your hips are slightly lifted, and the pressure from your weight from above will be removed. The sliding part of the seat is designed to slide smoothly along the support rod, so the load can be constantly applied at a position that allows for optimal running conditions without being stuck in the 7-sided position. can be taken as a thing.

In addition, by sliding the tip of the ski worn by the rider in the lateral direction and also sliding the handle 24 in the same lateral direction, the rider can easily turn the ski in either the left or right direction.

Further, as shown in Fig. fjS'1, the support rod 22 stands upright from the front part of the frame by a predetermined length, and then extends rearward with an inclined surface, and furthermore, a horizontal portion is formed at the rear end. (The curved shape makes it easier to select a position F that is easy to ride in the correct posture according to each inclination angle, that is, a position F suitable for driving, and the rubbing part consisting of the handle 24 is integrated with the support rod.) This makes it easy to change direction, etc., and allows for well-balanced boarding.
By supporting one end, it is possible to make the support rod simple and lightweight, and even when the support rod is made detachable or rotatable, it is possible to make the support rod at one end. 'It is easy to assemble, disassemble, or rotate and store, making it easy to handle when skiing downhill with the product of the present invention on your back.

(Example: jS2) Next, an example showing the present invention more specifically will be described in detail.As shown in the fjSs and fjsT diagrams, for example, a metal tube is formed to constitute the ma section of a rectangular parallelepiped. A mounting slope is provided at the bottom of the frame 50, and the front and f& portions of the plate are provided with a mounting plate at a predetermined distance BE so as to be sandwiched between the mounting plates fixed to the frame. Become the axis of movement! A rear main shaft 52 and a rear main shaft 53 serving as a driven shaft are rotatably supported via bearings (not shown), and two sprockets 54 are attached to the main shaft 52 and the rear main shaft 53.
54 and 55, 55 are fixed, and endless chains 56, 56 are stretched respectively between the sprockets 54, 54 fixed to the main shaft 52 and the sprockets 55, 55 fixed to the rear main shaft, Caterpillars 57, 57, etc., each having a cross-section shaped like a letter L, are arranged on the outer circumferential surfaces of the endless chains 56, 56, with the two endless chains connected in a bridge-like manner, and separated by an appropriate dimension.
8 is formed.

Further, inside the substantially rectangular parallelepiped space of the frame, an ennon 59 as a driving force is positioned above the traveling means and placed on the frame, and the shaft 6 of the ennon 59 is located above the traveling means.
A chain 550 is stretched between the small sprocket 61 fixed at 0 and the input extended from the clutch machine 1162 of known structure. Kura, Chisha 7)
5.6 between the small pulley 570 fixed to I) and the large pulley 600 fixed to the input shaft 590 of the device 580, e.g. A toothed belt 610 is stretched, and a drive chain 650 is stretched between a small sprocket 630 fixed to the output shaft 620 of the transmission device 580 and a drive sprocket 640 fixed to the menshu pongee. This provides a groove for transmitting the rotational force of the ennon to the traveling means.

Further, in the front part of the frame 50, a holding rod 66 is rotatably supported on the upright left and right frame bones 50A, 50A, 1Jl, and has a stopper (not shown) for stopping and holding the support rod, which will be described later, in an upright state. A support ring 67 formed in a hollow shape is fixed to the support ring 67, and the inside of the support ring 67 is
! A support rod 68 having the shape as shown in the figure is inserted into the pipe portion 67A and fixed at an arbitrary height with a set screw 69.The support rod 68 marked mj has a lower opening as shown in FIG. A seat 70 (z; 1Jlc is movably attached to both sides of the sliding body 70A bent in a U-shape and a hanging body 70B made of a metal pipe bent in a C-shape is welded to both sides of the sliding body 70A, An operation handle 71 is fixed to the front part of the support rod 68, and the height can be adjusted by loosening a set screw 69 and moving the support rod 68 up and down to suit the physique of the user. , and a holding rod 66 that can be rotated freely.
After removing the stopper and rotating the support rod 68 horizontally by 180 degrees as shown by the arrow R, it can be folded by rotating it approximately 20.0 degrees on a vertical plane as shown by the arrow.

Therefore, when not using the product of the present invention, adjust the height of the support rod 68 according to the physique of the person using it, securely fix it with the set screw 69, activate the skis, and attach the skis to the feet. In this state, sit astride the seat 70, hold the operation handle in your hand, operate the lever (not shown) installed at the appropriate position on the handle, open the throttle valve, and increase the rotation speed of the Ennon by 2 to activate the well-known automatic positive 6 clutch. The rotational force of the ennon shaft is transmitted to the transmission, where it is decelerated to a predetermined rotational speed and transmitted to the running means 56, which is an endless chain provided with caterpillars. By driving the traveling means 58, it is possible to climb up the snow surface steadily, and the seat 70 can be adjusted according to the angle of the slope.
It is possible to efficiently climb a snow-covered slope by shifting it back and forth in the same manner as described in the above embodiment, and when skiing from the top of a mountain, the support rod etc. can be removed or folded as shown in Fig. 8. You can enjoy skiing by carrying it on your back using the provided backpack strap.

In addition, the seat is made of metal, and has been ideal as a seat for snow-driving vehicles used outdoors for many years, and when the back row of the thighs touches the curved part at the rear of the bent metal pipe, when the seat is moved backwards. The stool can be securely held and slid and locked at the JΔ position, and
The narrow midsection is held between the crotches and pressed against the front upper part of the midsection to create a seat that allows for forward movement and increases stability during ascending. ing.

In addition, in an emergency, by moving the crotch between the 8 legs that are in contact with the seat with a distance of 51L, it is possible to separate from the S upper drive vehicle rearward, and there is no protrusion forward. It is designed with safety in mind, with no snags, and the handle can be removed by climbing over the smoothly curved pipe structure handle.

``Effects of the Invention J'' As described above, the present invention has a power transmitting means such as a motive force (a motive force is placed on it, a clutch connected to the motive power is disposed inside the frame, and a groove is used for speed change). , in the snow surface drive vehicle having the traveling means driven by the prime mover via the power transmission means at the bottom of the frame, the support rod and the handle that support the IIl hook are removed;
1. By creating a structure that allows self-storage inside or near the frame, the inclination angle of the snow surface on which the vehicle is traveling can be reduced.
Instead of having to easily and quickly move the seat to the optimal position according to the situation, we have developed a safe and convenient snow surface drive r11 that is easy to operate such as changing direction.
