 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1A is a perspective view of a base frame 1, and FIG. 1B is an external view in which a part of a hose coupling 2 is cut away. The base frame 1 and the hose coupling 2 constitute the apparatus for switching the artificial snow distribution line of this embodiment.

First, the base frame 1 will be described. The base frame 1 is entirely made of metal and has a pair of angle members 3 provided along the longitudinal direction, and both end portions of the pair of angle members 3. And a pair of support plate portions 4a and 4b respectively installed on the support plate portions 4a and 4b.

At both ends of each of the support plate portions 4a and 4b, a bar portion 5 formed by bending a wire having a predetermined diameter into a substantially U-shape is provided. The bar portion 5 is provided at the upper ends of the support plate portions 4a and 4b so that the base frame 1 is placed on the snow so as to prevent slipping on the snow. It is inclined.

One support plate portion 4a is provided with an introduction-side hose fixing body 6 for fixing a hose on the introduction side (the side of the snowmaking apparatus), and the other support plate portion 4b is provided on the slope side. Here, first and second outlet-side hose fixing bodies 7A and 7B for fixing a plurality of hoses extending to the first and second hoses are provided.

Each of the hose fixing bodies 6, 7A, 7B has a vertically divided structure. That is, each hose fixing body 6, 7A, 7B has a receiving portion 8 fixed on the support plate portions 4a, 4b, and a holding portion 10 detachably fixed to the receiving portion via a fixing tool 9. Consists of

Here, the upper surface of the receiving portion 8 is formed in a semicircular shape, and the pressing portion 10 is bent in a semicircular shape between the flanges attached by the fixture 9. As a result, in a state in which the holding portion 10 is combined with the holding portion 8, the cross section thereof has a circular shape with a predetermined diameter. Therefore, after the hose is fitted therein as described later, the fixing tool 9 is fastened. Thus, the hose can be reliably held without crushing the hose.

As shown in FIGS. 1A and 5A, the axial direction La of the introduction-side hose fixed body 6 is arranged to be inclined by a predetermined amount with respect to the direction of the center line Lb of the base frame 1. There. Then, on the extension of the introduction-side hose fixing body 6 in the axial direction La, for example, the first outlet-side hose fixing body 7A is disposed so as to be inclined with the axial directions thereof aligned.

On the other hand, the second outlet side hose fixing body 7B is attached so as to be in the axial direction Lc inclined in the opposite direction with respect to the first outlet side hose fixing body 7A. The axial directions La and Lc of the hose fixing bodies 7A and 7B are expanded substantially in a fan shape.

Next, the hose coupling 2 will be described. As shown in FIG. 1 (B), the hose coupling 2 is made of, for example, a synthetic resin material, has a predetermined axial length, and has an inner diameter substantially equal to the hose outer diameter to be connected. ing. In addition, the diameter of the other end 2b is slightly smaller than the diameter of the one end 2a, and the whole is tapered.

Further, a spiral groove 11 is formed on the inner peripheral surface of the hose coupling 2, and the pitch of the groove shape is equal to the spiral groove formed on the outer peripheral surface of each hose to be connected. ing. Further, in this embodiment, the outer peripheral surface of the hose coupling 2 is subjected to a high friction treatment 12 having a rough uneven surface. Instead of the high friction processing, a high friction material may be attached to the outer peripheral surface.

Next, a method of using the apparatus for switching snow lines for artificial snow will be described with reference to FIG.

As shown in FIG. 2, an end portion of the introduction side hose 13 extending from the artificial snow making apparatus S is fixed to the introduction side hose fixing body 6 on the base frame 1. At this time, by removing or loosening the fixture 9 of the introduction-side hose fixed body 6, the holding section 10 is removed from the receiving section 8, and the end of the introduction-side hose 13 is inserted into the fixed body 6. I do. Then, with the distal end of the introduction-side hose 13 protruding from the fixed body 6 by a predetermined amount, the holding portion 10 is fastened and fixed with the fixture 9. This ensures that the end of the introduction-side hose 13 extended from the snowmaking apparatus S is securely fixed and held by the introduction-side hose fixing body 6.

In the same manner, the ends of the first and second snow-spreading hoses 14 and 15 extending to different portions Ga and Gb of the slope G are attached to the first and second outlet-side hose fixing bodies 7A and 7B, respectively. Fix the part. For example, as shown in FIG. 6, when the snowmaking apparatus S is disposed on one side of the slope G, the end of the first snow hose 14 extending to one side Ga of the slope is the first end. The end of the second snow-spreading hose 15 that is fixed and held by the outlet side hose fixing body 7A and extends from one side of the slope to the side opposite to the shore Gb through the lower side of the slope, is connected to the second outlet side hose fixing body. 7B.

Next, the end of the introduction hose 13 and either the first snow hose 14 or the second snow hose 15 are connected to each other via the hose coupling 2. For example, the work of connecting the end of the inlet hose 13 and the end of the first snow hose 14 with the hose coupling 2 is performed as shown in FIGS. 3A and 3B.

That is, first, as shown in FIG. 3A, the hose coupling 2 is screwed into the end of the introduction side hose 13. At this time, since the same spiral groove 11 is formed on the outer peripheral surface of the introduction side hose 13 and the inner peripheral surface of the hose coupling 2, the hose coupling 2 is smoothly screwed by turning in a predetermined direction.

Moreover, since the outer peripheral surface of the hose coupling 2 is subjected to a high friction treatment, an operator can easily and surely turn the hose coupling 2 without slipping the hand.

Then, most of the hose coupling 2 is screwed into the introduction-side hose 13 so that there is a certain gap between the end face of the hose coupling 2 and the tip of the first snow hose 14.

Next, the end of the hose coupling 2 and the tip of the first snow hose 14 are opposed to each other, and the hose coupling 2 is turned in the opposite direction. The hose coupling 2 gradually emerges from the extension hose 13 and is screwed into the tip of the opposing first snow spray hose 13. At this time, since the hose coupling 2 is formed in a tapered shape and has a large diameter, the hose coupling 2 can be easily inserted into the end of the first snow hose 14.

When the hose coupling 2 is turned in the opposite direction, the hose coupling 2 connects both ends of the hoses 13 and 14 to each other, as shown in FIG. . At this time, since the axial direction Lb of the inlet-side hose fixing body 6 and the first outlet-side hose fixing body 7A coincide with each other, the rotating operation can be performed with the hose coupling 2 kept straight, and the work is easy. It is.

According to the above-described procedure, the apparatus can be used as an apparatus for switching a snow-dispersion line for artificial snow, and the artificial snow produced by the apparatus for producing snow S is sent to the apparatus for switching a snow-dispersion line by the extension hose 13. Then, snow can be sprayed from the first snow hose 14 connected to the hose coupling 2 to the slope side Ga.

When the first snow hose 14 finishes snowing from the ski on one side of the slope, the hose coupling 2 is connected to the first snowing line in order to switch the snowing line so as to spread snow from the side of the slope Gb. The connection can be switched from the snow hose 14 to the second snow hose 15.

This operation may be performed manually by an operator as shown in FIGS. 4 (A) to 4 (B), whereby the snow dispersion line is changed from FIG. 5 (B) to FIG. Switching can be performed as shown in (C).

That is, first, the hose coupling 2 is once moved to the extension hose 13 side of the artificial snow making apparatus S by turning. This disconnects the hose coupling 2 from the first snow hose 14.

Next, the hose coupling 2 is turned in the opposite direction, and is transferred so as to be connected to the second snow spray hose 15. At this time, although the axial direction Lc of the second outlet side hose fixing body 7B is different from the axial direction Lb of the introducing side hose fixing body 6, the hoses 13, 15 and the hose coupling 2 have flexibility. The connection can be made without any trouble simply by bending the hose.

When the connection switching is completed by the attachment / detachment work to the hose coupling 2, the snow can be spread from the piste side Gb via the second snow spray hose 15. If this snowfall is completed and further snowfall from the lower side is required, the configuration is as shown in FIG.

That is, another snow-dispersion line switching device Kb is disposed at the tip of the existing snow-dispersion line switching device Ka, for example, at the tip of the first snow-dispersion hose 14, and the hose coupling 2 of the hose 14 tip and the switching device Kb is connected. The first snow hose 14 or the second snow hose 15 may be connected as described above.

As long as the snowmaking apparatus S is under the influence of the pumping force for pumping the artificial snow, it is possible to continuously snow the plurality of snow-driving line switching devices, and the snowfall on the lower side is reduced. it can. Of course, in each snow-spreading line switching device, the snow-spreading line can be easily switched between the slope side Ga and the opposite shore side Gb.

For the hose 13 and the first and second snow-dispersion hoses 14 and 15 extending from the snow-making apparatus S, for example, vinyl hoses are used. Because it crawls, it is easily damaged.

If the damaged portion is left untouched, artificial snow to be sprinkled from here or air for pumping the artificial snow leaks, and the amount of snow spread decreases. Therefore, it is necessary to repair this damaged part and prevent leakage.

At this time, the hose coupling 2 is used for repair. Specifically, first, as shown in FIG. 7A, a damaged portion Z generated in the hose H is confirmed. Next, as shown in FIG. 7 (B), the vicinity of the damaged portion Z of the hose H is cut using an appropriate cutting tool T such as scissors, and divided into hoses Ha and Hb. Alternatively, cutting may be performed along the damaged portion Z.

Then, as shown in FIG. 7 (C), a separately prepared hose coupling 2 is screwed into one of the cut hoses Ha, and then screwed into the other hose Hb to separate the ends of the separated hoses Ha, Hb. Connect the departments.

As a result, the hose coupling 2 completely covers the damaged portion Z, and it is possible to prevent leakage of artificial snow or air to be pumped. In this manner, the hose coupling 2 for connecting the hose also serves as a repair tool, so that the hose H can perform snow dispersion as before.

Since the hose coupling 2 as a repair tool is screwed between the hoses Ha and Hb, the hose coupling 2 does not peel off like a conventional adhesive tape, prevents leakage for a long time, and improves reliability. Can be

[0053]
