JP5252542B2 - A mechanism for changing the support position of an attachment in a bed - Google Patents

Description

  The present invention supports attachments on a bed, for example, a board (headboard, footboard) attached to the end of the bed in the longitudinal direction, and accessories such as side rails and IV poles attached to the end of the bed in the width direction. The present invention relates to an attachment support position variable mechanism in a bed that can be applied to change of the bed length or floor width of the bed by making the position changeable.

  For example, if the bed length of a bed used by an elderly person or a sick person in a hospital or at home is short, the usability is poor, and if it is longer than necessary, the required space becomes large. Therefore, in addition to the standard floor length bed, the manufacturer can provide shorter or longer beds.

  Conventional methods for constructing beds with different floor lengths include a method of providing different bed frames for each floor length, a method of extending the floor length by retrofitting an extension frame on the head side or foot side of the bed, A method of allowing the frame on the foot side of the bed to be extended in a sliding manner has been performed.

  In addition, in patent document 1, the support stand which supports the bottom of a bed is comprised from a head support stand, a foot support stand, and an intermediate support stand, and the space | interval between them is comprised so that adjustment is possible, floor length is made. It is configured to be adjustable.

  In Patent Document 2, the bed frame is composed of a bed frame and a foot frame, a telescopic side frame between them, and an inner and outer joint connected to the head side side frame. The floor length can be adjusted by advancing and retracting the foot-side side frame with respect to the joint.

  And in the above beds, the support mechanism for attaching and supporting accessories, such as a side rail and IV pole, is provided in the side part. As this support mechanism, for example, as shown in Patent Document 3, a mechanism for attaching an accessory support member by providing an attachment hole in a longitudinal member of a bed frame that supports the bottom is often used.

  On the other hand, in the bed, two types of floor width, that is, bottom width, for example, 830 mm and 910 mm are often used.

  In order to allow attachment of accessories such as side rails to predetermined positions of the bed frame even when such bottoms having different floor widths are used, conventionally, a bed frame having a different width for each bottom having a different width. Is configured.

In addition, in Patent Document 4, the width of the bed frame is made to correspond to the floor width of the bottom only by changing the head frame and the foot frame without exchanging the middle frame.

In the above conventional techniques, there are the following problems concerning the floor length.
1. In the method of providing a different bed frame for each floor length, a bed frame corresponding to the type of floor length is required, which increases manufacturing costs and management costs.
2. In the method of retrofitting the extension frame, the size of the extension frame is relatively large, so that storage and mobility are poor.
3. In the method in which the frame can be extended in a sliding manner, the mechanical parts become large, leading to an increase in the number of parts and an increase in manufacturing costs.
4). In the method as shown in Patent Document 1, there is a restriction on the configuration of the bed, and in the method as shown in Patent Document 2, the bed frame must be disassembled when changing the floor length, which is troublesome. .

Moreover, in the above conventional technology, there are the following problems with respect to the floor width.
1. If different bed frames are configured for the bottoms having different widths so that the accessory can be attached to a predetermined position of the bed frame, the cost becomes high.
2. As in Patent Document 2, a part of the bed frame, that is, the inner frame is made common to different bottom widths, but since the part is made common, the cost reduction effect is relatively small. Is also troublesome.
The present invention aims to solve the above problems.

In order to solve the above-described problem, in the present invention, the attachment support member is detachably supported in the longitudinal direction of the rod-like member on the bed frame side, and the attachment member can be engaged with the rod-like member.
