Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front entrance frame for an elderly person, a sick person, a young child or a person who has difficulty walking, which is provided as needed between the entrance soil of the entrance and the entrance frame. The present invention relates to providing a convenient entrance slope for getting up and down at a location, entering and exiting with a wheelchair, and the like.

[0002]

2. Description of the Related Art Generally, in the entrance area, the appearance is adjusted,
In order to prevent intrusion of dust from the outside, an ascending frame is provided in a form one step higher from the soil to separate the entrance soil from the ascending floor.

[0003] The steps provided at the entrance as described above hinder the entry and exit of elderly people, young children and people who have difficulty walking, and also hinder entry and exit by wheelchairs. Was.

[0004] In view of the above, there has been a configuration in which a slope portion is provided on the side of an upward frame portion at the entrance, and the slope portion is used to enter and exit the elderly and the like, enter and exit by a wheelchair, and the like.

[0005] However, such a configuration in which the slope portion is permanently provided in the upstairs frame portion of the entrance is not applicable except when the entrance is wide, and has a drawback such as intrusion of dust from the outside. Was.

[0006] From such a point, it is usually used as an entrance provided with an upstairs frame, and, if necessary, a slope is formed between the upstairs and the entrance soil to be used by people or wheelchairs. It has been tried to be.

[0007] The slope set at any time at the entrance is, for example, a slope base provided with a plate-like tread surface convenient for walking or wheelchair traffic so as to extend between the dirt floor and the uphill frame. There was one that was prepared and used at any time as needed in the front entrance area.

[0008]

However, in such a method of setting and using a separately prepared slope base, the separately prepared slope base is required to be connected to the entrance as needed. It is necessary to carry in and set, and after use, it is necessary to remove the set and carry it out, and there is a problem that much labor is required for carrying in and out the slope table.

In addition, when the slope base prepared separately in this way is used between the entrance lands, the slope base is set one by one in a state where the slope base is in contact with the upward frame and does not move when used. In addition, there is a problem that the setting and resetting require a lot of trouble and time, for example, a process of removing the set is required after use.

In addition, the slope table which is separately prepared and used at the entrance is required to have a size corresponding to the use of the slope table, and the length of the slope is limited. .

[0011] In addition, in the case of the slope base which is separately prepared and used at the entrance, it is necessary to separately prepare relatively large storage means such as a storage locker for storing the slope base. .

The present invention solves such a problem at the conventional entrance, and can be easily pulled out and used when necessary, and after use, it is pushed in from the bottom of the frame toward the floor and stored. The purpose of the present invention is to provide an easy-to-use entrance slope which can be easily stored by carrying out.

[0013]

In order to achieve the above-mentioned object, the invention according to claim 1 is accommodated in a storage space provided from the lower part of an upward frame to the lower part of the upward floor part. One or a plurality of slope bodies that are provided to be able to be pulled out to the side between the entrance lands and the slope body that is drawn out to the side between the entrance lands, and one end side thereof is in contact with the front side of the entrance soil, and the other end side is an up frame part. And a support means for supporting the vehicle in a lifted state so as to follow the entrance slope.

In the thus constructed entrance slope, if necessary, the slope body is pulled out from the lower part of the upward frame to the side between the entrance soils, and the slope body drawn out to the side between the entrance soils is inserted into the entrance slope. With one end side in contact with the porch, the other end is supported in a lifted state so as to be along the upstairs, and a slope with a required slope is formed between the upstairs and the porch. can do.

In the entrance slope configured as described above, when a slope portion is not required at the entrance, the slope body is provided from the lower side of the ascending frame portion to the lower side of the ascending floor portion. The entrance can be used as a entrance without a slope by putting it in the storage space where it is located.

Next, in order to achieve the above object, the invention of claim 2 is replaced by the invention of claim 1,
A supporting means is rotatably provided at one end side of the slope body and can be pulled out from the storage space together with the slope body to the side of the entrance soil. A base portion at least part of which is fixed to the storage space so that at least a part of the upper surface side is in contact with a part of the constituent surface of the storage space when the drawer is drawn toward the entrance soil, And a rotation preventing means for maintaining the rotating body standing upright along the front surface of the frame portion in an upright state.

In the entrance slope configured as described above, when a slope is required at the entrance, the slope is pulled out from the storage space below the up-frame, and turned to one end of the slope. One end of the slope body is lifted so that the rotating body movably provided and pulled out of the storage space along with the slope body from the storage space to the front of the entrance frame along the front surface of the up frame portion, and The rotating body thus formed can be used by being prevented from rotating by the rotation preventing means so as to maintain the upright state.

In the case where a slope is not required at the entrance, the rotating body which is prevented from rotating and maintained in the upright state is rotated by the rotation preventing means which prevents the rotating body from rotating. Releasing the obstruction and turning so as to fall to the side of the entrance soil, the rotating body that has been fallen down to the side of the entrance soil and the slope body attached to this are raised from the lower part of the frame part to the floor part. It can be stored and stored in the storage space provided for.

Next, in order to achieve the above object, the present invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the slope body comprises a plurality of slope components. It is as an entrance slope.

In the entrance slope configured as described above, slope bodies having different slope lengths can be provided as needed between the upward frame and the entrance soil.
