The conventional simple slope described above is portable, can be easily installed to eliminate steps, and can be removed when not needed, but if the steps are protruding, for example, the threshold of an old house, it is simple. Two simple slopes, one for climbing and one for descending, are required as slopes, and if the two simple slopes are hung shallower than both sides of the step so as not to interfere with each other, it is easy to climb up and down the simple slope. The slopes are easier to come off than the steps, and even if the simple slopes hit each other on the steps and hang deeply on the steps, when moving the top of the abutting part with a wheelchair etc., the simple slopes easily jump up and get over the steps. Becomes difficult.

An object of the present invention is to provide a simple slope attached to a step in order to solve the above problem and make the protruding step barrier-free.

The invention according to claim 1 is a simple slope that is attached to a protruding step so as to be barrier-free, and can be opened and closed by being connected to a first slope plate for climbing by a hinge. It consists of a second slope plate for descent and a link connecting both slope plates in a mountain shape, and at least one end of both ends of the link is detachably connected to the first or second slope plate. When the simple slope is placed on the step, the simple slope which is in contact with the step or is located above the step has at least one end of both ends of the link and at least one of both slope plates. Of the side ends of one slope plate, one has a long hole, and the other has a bolt means inserted into the long hole and a nut means screwed into a bolt means protruding from the long hole. It is characterized by that.

According to the present invention, a mountain shape concatenated slope plate by the link is used placed over the rows above addition can be climbing down it is a step is eliminated by the mountain-like barrier-free condition, not used In some cases, by removing at least one end of both ends of the link from the slope plate, both slopes can be closed and folded, which makes it easy to carry and reduces the storage space. Further, by adjusting the mounting position by the bolt means within the range of the elongated hole, the angle at which both slope plates are connected can be changed steplessly, so that the link is brought into contact with the step according to the height of the step. It can be put on the step in a supported state, and even if a wheelchair or the like moves on it, the rigidity is insufficient when getting over the top where both slope plates are connected, and even if it bends. , The link comes into contact with the top and is supported, which enables stable movement.

The other slope plate 2b is a second slope plate for descent. Here, the first and second slope plates 2a and 2b have the same shape and the same size, but one of them may be longer than the other.

The side ends of both slope plates 2a and 2b near the hinges are connected and fixed by links 4 on both front and rear sides. As shown in FIG. 2, the link 4 has one end rotatably attached to the side end of one slope plate 2a near the hinge by a shaft 5, while the other end has a downward opening. A stop groove 6 is formed, and the locking groove 6 is fitted and locked to a pin 7 projecting from the side end of the other slope plate 2b so as to be engaged and disengaged from above, and the slope plates 2a and 2b are mountain-shaped. It is connected to.

The slope plates 2a and 2b are connected by the link 4 before and after both the slope plates 2a and 2b, so that the simple slope 1 fixed in a mountain shape does not hinder climbing up and down on it with a wheelchair or the like. It is configured to have sufficient strength.

FIG. 3 shows a simple slope 1 in a used state, and the slope plates 2a and 2b are covered on the step 8 in a state of being connected in a mountain shape by a link 4. When not in use, the link 4 is rotated counterclockwise around the shaft 5 to separate the locking groove 6 from the pin 7, and the slope plates 2a and 2b are closed with the link 4 free. , Fold it in half. In the figure, reference numeral 9 denotes a handle used when transporting the simple slope 1.

In the above embodiment, since the locking groove 6 is opened downward, the pin 7 acts to bite into the locking groove 6 even if a load is applied to the simple slope 1 during use, and the pin 7 does not come out of the locking groove 6. However, it is also possible to form the locking groove 6 in the shape of a hook so that the inserted pin 7 does not easily come out.

In the above embodiment, one end of the link 4 is rotatably attached to the side end of one slope plate 2a by a shaft 5, but a locking groove 6 is formed like the other end. A pin 7 projecting from one of the slope plate side ends may be fitted and locked in the locking groove 6.
