[0002]

2. Description of the Related Art Conventionally, in hotels and other accommodation facilities, as one of the important work departments, bed making for newly preparing a bed surface of a bed apparatus for the purpose of preparing for the next accommodation has been carried out. It is done every day.

[0003] Here, for example, when the bed body to be maintained is used by directly installing the bed body on the floor surface without using a bed frame, the required bed apparatus is required from the installation floor surface. Height (generally, approximately 400mm
(Approximately 500 mm), and the bed body surface is laid with a relatively thick mat or mattress as a bedding underlay member.
The surface of the mat or mattress, etc. is wrapped with an underlay sheet, and is used by overlaying a blanket or futon with a quilt according to the indoor temperature environment according to the season. After use by a guest or the like, it is necessary to replace and re-maintain these beddings, in particular, sheets or hanging cloths covering the beds of beds, for example, by replacing them.

[0004]

However, in the case of the above-described conventional bed making, for example, regarding replacement of an underlay sheet, the making worker once pulls out the bed body itself to the near side. Then, the work of removing used sheets from the bed surface and replacing them with new sheets is performed.

However, during the making operation, since the upper surface of the bed apparatus is fixedly located at a fixed height from the floor, the height of the worker performing the making operation depends on the height of the worker performing the making operation. Is forced to take an unreasonable work posture in the middle waist state with a slightly bent waist, which makes the work itself inefficient and moreover, this type of work is performed by relatively elderly female workers This often causes back pain and the like, and is unacceptable for long-term work.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to enable a worker to easily and easily perform a making operation in a reasonable posture. And an exchange device for sheets and the like in bed making.

[0007]

In order to achieve the above object, according to the present invention, there is provided a mattress which is used as an underlay member on a bed body and as an underlay member on the bed body to be overlaid on the upper portion of the bed body. A bed exchange device that has a bed device composed of a bed pressure member and the like, and replaces sheets and the like that cover the bed pressure member to perform bed making. In a normal state, the device is flattened as much as possible. An air mat member which is formed into a bag-like shape, and which can be inflated to a required extent in the vertical direction by pressurized air introduced into the bag-like shape, and supplies compressed air to the bag-like interior of the air mat member by blowing air And a configuration in which the air mat member is inserted into the upper surface of the bed body to support substantially the entire bed body, and the air mat member is inserted into the bag-like interior. The blast The supply adjustment of the pressurized air amount due to location, is characterized in that the arbitrarily set the height position of the bed decubitus body with respect to the bed body.

In the apparatus for exchanging sheets and the like according to the first aspect of the present invention, when the pressurized air is not introduced into the air mat member supporting substantially the entire bed, the air mat member itself can be used as much as possible. Since the air mat member is flattened, the bed device can be used for sleeping in a normal state, and when the pressurized air is introduced into the air mat member from the blower, the air mat member is vertically raised. The bed expands in the vertical direction, and the height of the bed body relative to the bed body changes. Therefore, the making operator can arbitrarily adjust the amount of pressurized air introduced into the air mat member, that is, the amount of pressurized air supplied from the blower, so that the actual height position of the bed Can be set in a state that facilitates making work according to the user's height or the like.
