Referring now to Fig. 2 there is shown an embodiment of the present invention including a net 2, which is strong enough to withstand a snow load, and a supporting frame 6 by which the net 2 is supported horizontally over a building l, with a space 3 left between the roof of the building l and the net 2. The supporting frame 6 comprises upright posts 4 and beams 5, the beams extending so as to form a square or rectangular upper frame at the top of the posts.
At the first stage of snowfall, only a small portion of the snow piles up on the net 2 as shown in Fig. la, and the remaining portion of the snow falls through the meshes 12 of the net 2. Soon the snow ll piles up on the net 2 to such an extent that it blocks up the mesches 12 as shown in Fig. lb. Then the snow ll stops falling through the meshes 12 and lies thicker and thicker on the net 2.
On the other hand, the sun gradually melts the snow ll lying on the net 2 by directly shining on the top and the side thereof. The sunlight reflected by the ground melts the under surface of the snow ll lying on the net 2, Wind and rain melt the top, the side and the under surface thereof. Thus the quan-tity of snow lying on the net 2 is always smaller than the quantity of snow which would lie on the roof of a building or a plate type snow shelter, Melted snow falls through the meshes 12 and does not require any special drainage.
In contrast to the above-mentioned embodiment in which -the supporting frame 6 for supporting the net 2 is built up 3~
separately from the building 1, there is another embodiment as shown in Fig. 3 in which the four corner stiles of the building 1 1 are extended upwardly beyond the roof and used as the upright posts 4 for forming the supporting frame 6.
In order to protect the building 1 from the snow driving against it, the net may be vertically arranged by th~
side of the building 1. In this case, the net has only to be arranged at the side against which the snow drives most fre~uently.
Referring now to Figs. 6a and 6b, two em~odiments of the invention are shown in which cultivated land 13 is provided with snow shelters. The first embodiment shown in Fig. 6a is suited for snowy and windy provir.ces. The snow falling from above is caught by the net 2 which is put up horizontally over the cultivated land 13, while driven or blown snow is checked by the net 2' which fences the cultivated land 13. The net 2' can be done without in areas free from driven or blown snow. The second embodiment shown in Fig. 6b is suited for provinces characterized by windy weather and comparatively little snowfall.
Since driven snow is the principal factor to be taken into consi-deration in such provinces, the net is employed only to fence the cultivated land 13.
Referring now to Fig. 7, an embodiment of the inven-tion is shown in which a garden 13' adjacent a house is provided with a snow shelter. An edge of the net 2 extends to the ground, permitting the vertical portion of the net 2 to serve both as a snow fence and as a hedge. But, the vertical portion may be omitted, In an embodiment shown in Fig 8, steel towers 14 standing at intervals along a railroad track 15 and supporting aerial lines 16 are used for supporting the net 2 over the rail-road track 15. The net 2 is partitioned into sections at the same intervals as the span of the steel towers 1~, and is .
~1~5~;~9 slackened in the central part of each section so that the snow piling up on the net 2 may not slip down to the grouna In an embodiment shown in Fig. 11, the supporting frame 6 for supporting the net 2 is laid across a high level road 19.
The supporting frame 6 comprises upright posts 4 and beams 5.
The upright posts 4 are made of iron, concrete, wood, etc. and are symmetrically arranged with respect to the center line of the road 19. Each beam 5 is supported at ~ts ends by a pair of symmetrically arranged upright posts 4. The supportlng rame 6 may comprise arched girders 20, as shown in Fig. 10, or cantilevers.
In the embodiments shown in Figs. 8 and 11, the vertical nets 2' are mounted on the sides of the steel towers 14 or the upright posts 4 in such a manner that the vertical net 2' is stretched in parallel with the railroad track 15 or the high level road 19, respect~vely, so that driven snow may be checked thereby. The net 2' can be omitted in those areas free from driven snow.
Preferably, the net 2 or 2' has about Q.5- to 5-cm meshes and is made of metal, synthetic resin, or synthetic resin coated metal. However, this limitation in mesh size is not restrictive according to the conditions of wind and snow under which the snow shelter in accordance with the present invention is used.
A lattice 2", as shown in Figs 4a and 4b, may be used in place of the net 2. The lattice 2" has long and slender meshes 12 formed by stringers 7 and cross members 8. The cross members ~ extend across the space between the stringers 7, and are connected therewith by connecting means 9 such as bolts and nuts. Holes 10 provided at regular intervals in the stringers Z~9 1 7 make the space between the cross members 8 adjustable accord-ing to the quantity of snowfall.
The lattice 2" may be of any other suitable structure, such as a woven structure as shown in Figs. 5a and 5b, or it may be formed by angle bars 17 as shown in Figs. 9a and 9b in which angle bars 17 extend across the spans between sub-posts 18 propped up against the steel towers 14. The L-shaped cross section of the angle bar 17 helps to check the snow falling aslant, i.e , from the top right-hand corner of Fig. 9b. The size of the cross section of the angle bar 17, as well as the vertical spacing between the angle bars 17, may be adjusted according to the quantity of snowfall.
The embodiments shown in Figs. 2 and 3 have an advan-tage that they free architects from the trouble of taking snow load into consideration in constructing a building in areas receiving snowfall. In addition, cultural properties and other superannuated buildings in these provinces can be e~sily preYented from being damaged by snow loads.
The embodiments shown in Figs. 6a, 6b and 7 have an advantage that farm work or the work necessary for flower growing can be done even while it snows. The embodiments shown in Figs.
8, 9a, 9b and 10 have an advantage that they protect the operation of trains from being hindered by snow and that, in case of the embodiment shown in Fig. 8, the use of special posts for support-ing the net can be avoided because of the steel towers 14 serving therefor. The embodiment shown in Fig. 11 has an advantage that, during the daytime, the road 19 is well lighted by the sunlight passing through the net 2.
With the snow shelter according to the present inven-tion, a larger quantity of snow melts per unit time as compared 11~5229 .
1 with the case where the snow piles up on the roof of a buildingor a plate type snow shelter, because sunlight, wind and rain not only melt the top and the side of the snow lying on the net or lattice, but also melt the under surface thereof. Because of this accelerated thawing of snow-, the net 2 or lattlce 2" and supporting frame 6 are subjected to smaller loads and hence require smaller strength than the conventional plate type snow shelter or the roo~ of the building d~rectly exposed to snowfall.
The snow shelter in accordance with the present inven-10 tion can be constructed at low cost and in a straight~orward -manner! It is~ o~ simple structure and yet sturdy enough to be used over a long period of time. Since the wInd blows through the meshes when the net or lattice is not snow-capped, it is seldom that the net or lattice is damaged by wind pressure. In case of the embod~ments shown in Figs. 6a, 6b and 7, plants grow up without hindrance because of sunlight, raln and wind admitted through the meshes~
While several embodiments o~ the present invention have been disclosed, it is to be understood that they have been given by way of example only and not in a limiting sense, the scope of the present inVention being dete~ined b~ the objects and the claims.
