Description

[Detailed description of the invention] [Industrial application field] This invention relates to a snow removal safety device that prevents workers from falling while shoveling accumulated snow from roofs to under eaves.

[Conventional technology and its problems]

To prevent houses from collapsing due to snow accumulation, it has been common practice to remove snow, but because the footing is extremely unstable, there is a high risk of slipping and falling.

As one of the safety devices to prevent falls,
As shown in the figure, there is one in which supports 10 are erected on both sides of a ridge, and a main net 11 is passed horizontally between the upper parts of the supports 10.

The above-mentioned safety device prevents falls by wrapping a safety belt B for high-altitude work around the waist of the snow removal worker A, and engaging the hook E at the end of the rope C connected to the safety belt B with the main net 11. I am trying to achieve this.

However, in the above-described safety device, since the main net 11 is located above the ridge, it takes time to engage the hook E at the end of the rope C, and it is also necessary to attach the post fixing metal fittings 12 to the house in advance. Moreover, in areas with heavy snowfall, the support columns 10 need to be made longer, which makes the support columns 10 easily deformed, which poses a problem in terms of reliability in terms of strength.

[Purpose of invention]

Therefore, the object of this invention is to provide a snow removal safety device with a simple structure that can eliminate the above-mentioned inconveniences and reliably prevent workers from falling.

[Structure of the idea]

In order to achieve the above object, this invention consists of laying a net on the upper surface of the roof, and having the tip of the main net connected to a part of the net hang down from the eaves.

[Effect]

With the above configuration, the net can be fixed by the weight of snow accumulating on the roof. Even if the net is buried in snow, the main net is located under the eaves, so the position of the main net can be easily confirmed.

Therefore, the main net is dug out by snow removal, and the rope chuck at the end of the rope of the high-altitude safety belt is engaged with the main net, and the snow is removed from around the main net. By engaging the tip of the rope and removing snow, snow removal work can be performed safely.

〔Example〕

Embodiments of this invention will be described below with reference to FIGS. 1 to 3.

As shown in Fig. 1, two nets 2 and 3 are laid on the upper surface of the sloping roof 1, and
Of these, the lower net 2 is used for the purpose of preventing the upper net 3 from shifting. For this reason,
It has a small mesh and is made of relatively thin rope.

On the other hand, the upper net 3 is used for engaging the rope connected to the safety belt for working at heights.
It is formed of a relatively thick rope with sufficient strength, for example, a rope with a rope diameter of about 30 mm, and the mesh is larger than the mesh of the lower net 2.

The size of the nets 2 and 3 is arbitrary, and since there are cases where the rope tip of a safety belt for high-altitude work is engaged with the upper net 3 to remove snow, at least the rope tip is engaged with the periphery of the net 3. There should be enough space to remove snow from the periphery of the roof.

A parent network 4 is connected to the upper net 3, and when the upper net 3 is installed, the parent network 4
It has a length that can hang down from the eaves of the roof 1.

Further, a plurality of ropes 5 are connected to opposite sides of the outer periphery of the upper net 3, and a carabiner 6 is attached to the tip of each rope 5.

The safety device shown in the example consists of the above structure,
Each of the nets 2 and 3 is laid on the roof 1 before snowfall and is fixed by the weight of the snow that accumulates thereon.

In this case, the tip of the main net 4 is made to hang down from the eaves of the roof 1.

Generally, in snowy regions, many houses have crosspieces 7 extending at right angles to the slope of the roof 1 to prevent falling snow, as shown in FIGS. 1 and 2. By installing the nets 2 and 3 on such a roof 1, each net 2 and 3 is connected to the roof 1.
Since the nets 2 and 3 follow the unevenness of the nets, each net 2 and 3 can be attached stably by the snow that accumulates thereon.

Further, since the rope 5 having the carabiner 6 can be engaged with the crosspiece 7, the stability of attaching the upper net 3 can be further improved.

When removing snow from the roof 1, as shown in Fig. 3, the rope chuck D at the tip of the rope C extending from the safety belt B for high-altitude work of the worker A is engaged with the main net 4 hanging from the eaves, and Snow is removed from around the main net 4, and if necessary, the rope C is engaged with the dug out net 3 to perform snow removal work from the entire roof.

〔effect〕

As described above, this invention involves engaging the rope of the safety belt for high-altitude work with the main net of the net, which is fixed by the weight of snow, and in some cases engaging the net rope to perform snow removal work. , snow removal work can be carried out extremely safely.

In addition, since the main net connected to the net is hung from the eaves, it is easy to find the main net even in heavy snowfall, and the main net has a rope chuck attached to the end of the rope of the safety belt for working at heights. Since the net can be engaged with the net, it is possible to safely remove snow around the main net and dig the net.

Furthermore, since a net with a main net is simply installed on the roof, the configuration is simple and the equipment cost is low, and many other effects can be achieved.
