Description

  The present invention relates to a snowdropper that scrapes off snow with a plate provided at the tip of a pattern longer than the ground against snow on a roof.

  If there is a large amount of snow on the roof, the snow on the roof places a burden on the eaves and may damage the eaves during heavy snowfall. This is particularly affected by the weather with the passage of days, and it becomes a snow-cuttered state due to repeated melting and icy snow. This snow-cage-like snow is heavy and hard, and the lower layer is often an ice plate. Also, it is bigger than the ridge and it is easy to make an icicle, so it is very dangerous to pass under this.

Therefore, when this snowfall is dropped, when dropping normal snow, a wide plate (for example, 60 centimeters wide and 20 centimeters high) at the tip of the handle, a right angle to the handle, Alternatively, it is provided in a shape that is easy to penetrate into the snow surface at a sharp angle. Although this form can be used when the snow is fresh or soft, it does not have any teeth on the snow that is heavy and hardened into a snow candy. In other words, the purpose of this snowfall board is to scrape fresh snow off the roof surface, and of course it cannot be handled if the snow conditions change.
The snow conditions can be broadly divided into two cases: fresh snow, repeated snow accumulation, and snow that is heavy and hard depending on the progress, and the lower layer portion is close to ice.

  There are many types of snow spilling boards that are used for falling fresh snow. Patent Document 1 includes a three-pronged part on the top of the snow squeezing board, so that the snow on trees (garden trees) can be removed. It is disclosed. Further, for a snow shed or an ice slab in the lower layer, a form of crushing the ice sack according to Patent Document 2 is disclosed as a snow shed drop. Moreover, this patent document 2 is provided with a spring on a hollow shaft, and it can be said that the effect of crushing the ice disk is great because an impact can be applied many times with the blade part applied to the ice sheet. In order to break the ice plate, it is necessary to repeatedly apply impacts to the same location. If there is no spring, even if trying to strike the same location, the handle is long and the tip is heavy, which is a very difficult situation. In this case, a structure using a spring is effective. However, this form is a method of crushing from the back side of the snow ledge that protrudes from the fence, and cannot be used for a portion that does not protrude.

  In addition, the method of using a spring is a structure in which the repulsive force of the spring is obstructed even if an attempt is made to press the handle and apply force to the blade part. Because it grows larger, it is inappropriate for the elderly, women and girls.

  In order to drop a snow plow, the shape of the tool that matches the situation is required. Here, since the number of days has passed, it is an object to provide a snowfall drop having a great effect on the snowfall that is heavy on the upper layer of snow that protrudes from the roof and is in the form of ice on the lower layer.

  The basic configuration of the snow plow dropping according to the present invention includes a handle and a crushing plate. First, as a form of scraping off the snow crab from above, it becomes the lower end of the crushing plate. The tip (sword tip) for crushing the ice plate is narrow, and the upper end is shaped like an inverted triangle widened to remove hard snow. The angle at which the crushing plate is attached to the handle needs to be an acute angle of 40 degrees or less. This is to pull the handle into the ice plate, which is the lower part of the snow. The sharper the angle is, the stronger the crushing force of the ice plate is. When the angle is obtuse, not only the crushing force is weak, but also a large force is applied to the attachment portion between the handle and the crushing plate, and it is easily damaged.

  Therefore, the crushing plate will crush the iced portion that is the lower layer of the snow candy, but naturally it can not be crushed simply by pulling the handle lightly, it is necessary to hit the blade part repeatedly on the same part There is. However, it is impossible to use a long handle. Therefore, it is necessary to apply an impact while holding the handle, that is, with the blade in contact with the ice plate.

  Therefore, it is assumed that a weight hammer is provided in the vicinity of the hand-held portion that is below the handle. This weight hammer is a cylindrical weight that can slide up and down outside the handle. By lifting this weight and quickly driving it down, it impacts a protrusion (underweight stopper) that stops the weight provided below. And this impact is transmitted to the blade of the crushing plate. By repeating this operation, the ice sheet is gradually crushed.

  Next, as in the case of Patent Document 2, when crushing from the back side to the portion that protrudes from the roof of the snow leopard, the crushing plate is reversed by rotation, the blade portion is provided above, and crushing from below the eaves of the roof. . Although it can be said that the operation is the same as that of Patent Document 2, it can be said that the impact effect is large by lifting the weight from below and hitting it against the upper weight stopper provided above.

  As described above, the crushing plate has a structure that bites into the snowfall, and the crushing effect is great for the snowfall that has become iced by repeatedly applying a large impact. Further, the conventional snowfall plate did not have teeth on hard snow, whereas the crushed plate according to the present invention surely digs into the snow.

  The embodiment will be described in detail. It is important that the snowdropper and snowfalling rod have a very long handle and are lightweight. On the other hand, strength and cost are reflected, and damage to the roof surface must be taken into consideration. Here, the material is not limited.

  First, as A in FIG. 1, as a form of scraping off the snow flakes, a blade part (1a) is provided at the lower side shown in FIG. 2, and the crushing plate (1) shown in FIG. 3 is fixed to the handle (3a) at an acute angle. A reinforcing frame (1b) is used to increase the fixing strength and the strength of the crushing plate. In this state, it can be hung on a snow canopy, and even heavy and hard snow can be scraped off little by little. However, if the lower layer is very hard and ice-like, it cannot be easily scraped off. Therefore, by applying an impact to the blade portion (1a) with the weight hammer (4) while the blade portion (1a) is applied, and repeating the operation, it is also possible to crush the ice sledge-shaped snow jar.

  When using a conventional snow removal rod, there is no problem in the case of fresh snow, but the snow after several days is a little heavy and hard, and when using it, the round pattern part does not enter the snow, The snow squirting board can't get enough effect. This can be discriminated from the form according to FIG. On the other hand, as can be seen from FIG. 2, the joint frame (2b) of the present invention has a thin plate shape, is easy to enter into the snow, and the crushing plate (1) is attached at an acute angle by pulling the handle. Therefore, the joint frame (2b) further penetrates into the snow. This shape can also be found in products that are currently distributed, and it can be said that it follows.

  Next, if it demonstrates as a form which crushes a snow crab from the lower surface as B in FIG. 1, it is necessary to make a blade part (1a) upward first. As this method, when the crushing plate (1) in the form of FIG. 2 is used by being reversed by the rotating part (2a), it is also a method of reversing by detachment, and a device of the snow dedicated plate and the ice dedicated plate by detachment. There is also a way to replace it. These should be dealt with according to the situation and are not limited. Therefore, the blade portion (1a) is provided on the upper side, and it hits against a snow jar that has become an ice disk from the lower surface, and is struck upward with a weight hammer (4).

  Next, as a supplementary matter, it is considered that a very large force is applied to the rotating portion (2a) due to the structure of the present invention. Therefore, as a structure for preventing damage, the shape of the attachment portion between the crush plate (1) and the joint frame (2b) needs to be a shape having a wide support range, a reinforcement frame, or the like. is there. The weight hammer (4) must have a function of fixing when the weight (4a) is not used. This is easy to hold when holding the handle (3a) and prevents injury due to unnecessary movement of the weight (4a). It is also effective to make the weight (4a) removable.
