Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device uses a part of the upstiles such as the entrance, and constructs a floor between the floorboards such as the entrance hall and corridor and the floor of the entrance floor such as concrete soil, as needed. Concerning the provision of the uphill frame that I got to get.

[0002]

[Prior art]

 At the entrances of wooden houses, etc., in general, there is often a relatively large step between the floor of the entrance floor such as concrete dirt and the floor of the entrance hall. , There was an inconvenience that hindered the entrance and exit of infants.

[0003] In addition, in the steps provided in such entrances, the lower steps of these steps are often composed of concrete dirt, etc., and as a result, people with disabilities, the elderly, infants, etc. may mistakenly enter the entrance. There were some cases where it fell from the hall to the concrete soil and injured.

[0004] From this point of view, a box-shaped bed or paving stone is usually provided on the dirt floor in front of the entrance sill, and the step difference between the dirt floor and the entrance hall is divided into two, which causes inconvenience during entry and exit. In particular, it eliminates the inconveniences of physically handicapped persons, the elderly, and infants when they come in and out, and makes it possible for these persons to come in and out without difficulty, and allows them to easily come in and out with heavy objects, or from the entrance floor Care was taken to prevent injuries as much as possible when the product fell.

However, the installation of such a bed or paving stone has a disadvantage that the efficient use of the entrance floor is impaired because the bed or paving stone is permanently installed on the entrance floor such as concrete soil. In particular, there were inconveniences such as obstacles such as walking or working on the entrance floor and obstacles such as cleaning.

[0006] In addition, such a bed or paving stone has a relatively high installation cost compared to the convenience brought about by use, and also has the disadvantage that it requires a lot of manpower and time for removal or movement. It has the disadvantage that it is difficult to deal easily with cases where it is desired to widely use the entrance floor such as concrete soil.

From this point of view, when not in use, the prepared bed is stored in a guide portion provided on an ascending frame toward the lower part of the corridor or floor, and if necessary, pulled out from the guide portion, There is a sill slide pedestal in which a pedestal is installed at the step between the dirt floor and the floor of the corridor. As a typical example of this underfloor slide bed, in the device disclosed in Japanese Utility Model Laid-Open No. 57-119031, a dirt floor is provided at the entrance of an entrance or the like, and a floor space such as a corridor is provided with a dirt floor. The figure shows a configuration with a slide bed that can appear and disappear in parallel to the surface.

[0008]

[Problems to be solved by the device]

 However, in this frame slide slide bed disclosed in Japanese Utility Model Laid-Open No. 57-119031, the slide bed provided at the stepped portion slides toward the inside of the guide portion as the storing means at the time of the ascending / descending movement when going in and out. If there is a risk, and if the slide bed is not sufficiently pulled out from the guide part as the storage means and fixed before the climbing and climbing operation, the slide bed is allowed to go up and down. Along with this, there is a risk that it may move further out of the guide part as a storage means, which both makes it difficult to climb and descend, and has the inconvenience that may cause accidents such as falls. .

The frame slide slide base disclosed in Japanese Utility Model Application Laid-Open No. 57-119031 has an object that abuts on the front edge side of the bed or is ridden by hitting the front edge. When a force is applied to the front edge in the direction in which the slide bed is retracted, the slide bed relatively easily slides into the guide portion as the storage means, and the bed cannot function as a bed. Had inconvenience.

The frame slide slide base disclosed in Japanese Utility Model Application Laid-Open No. 57-119031 has a structure for smooth sliding in and out of the slide slide base and a slide base that is sufficiently used for pulling out. In order to provide a support structure that can bear the load, the structure of the guide portion used as the storage means of the slide bed is complicated, and the construction of the guide portion requires a lot of construction work. Was.

In view of the inconvenience of such a conventional lower slide slide base, the present invention functions as an upstile such as a front entrance when not in use, and also functions as a base during climbing and descending movements such as entrance and exit. At the same time, the auxiliary sill that also functions as a sill may move inadvertently due to climbing and descending movements when entering or exiting, or the action of pushing force on the front edge of the auxiliary sill that also serves as a sill. The purpose is to provide an upstream frame with no configuration.

[0012]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, an upstile 1 such as a front door according to the present invention is, in the invention of claim 1, a upsole 1 including a frame body 1a and an auxiliary frame 1b serving also as a base. The upper surface 18 of the frame main body 1a and the upper end surface 17 of the upstanding stand-only auxiliary frame 1b are substantially flush with each other, and the bed-supporting auxiliary frame 1b also serves as the upright stand. The lower frame 20 of the auxiliary frame 1b is used as a rotation center S, and the upright frame 1 is configured to be rotatable in the front direction of the upright frame 1 until it is substantially horizontal.

Next, in the invention of claim 2, in the ascending frame 1 provided with the above-mentioned bed-supporting auxiliary frame 1b, after raising the table-cum-supporting auxiliary frame 1b in the upright state, it is moved upwards. With the lower side 20 of the bed / auxiliary support frame 1b being raised and standing up as the center of rotation S, it can be rotated in the forward direction of the uphill frame 1 until the base / combination support frame 1b is substantially horizontal. Thus, the upstream frame 1 is configured.

[0014]

[Advantageous Effects] The base / auxiliary support frame 1b is configured to be rotatable about the lower side 20 of the upright / support base support frame 1b as the center of rotation S until it becomes substantially horizontal in the front direction of the uphill frame 1. Therefore, the auxiliary bed 1c that serves as a base that has been rotated to be substantially horizontal functions as a base, and the auxiliary base 1b that also serves as a base before turning, that is, in an upright state, is a conventional one. It functions as an uphill frame.

After lifting the bed-supporting auxiliary frame 1b in the standing state, the standing-board supporting frame 1b in the lifted position has the lower side 20 as the center of rotation S for the rising frame. Since it is configured to be rotatable in the front direction of FIG. 1 until it becomes substantially horizontal, the space L ′ between the upper end surface 17 and the rotation center S of the upstanding platform / auxiliary frame 1b is standing. Can be provided to be relatively large with respect to the distance L between the upper surface 18 of the rising frame 1 and the surface of the entrance floor 2 such as concrete soil.
