Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for assembling a starting portion such as a floor portion of a bed that is simple and does not require tools.

[0002]

[Prior Art]

 In recent years, the percentage of elderly people in Japan has been increasing, and the need for home-based care has become more and more pronounced. For this reason, the demand for home beds has increased, and in order to reduce the labor of caregivers and the elderly, those equipped with an adjustment mechanism for the floor part (handle drive type, electric type, gas spring type) are becoming popular. is there. In the case of the above-mentioned home bed, in order to make it easier to transport, it is suitable to use a structure in which individual components are packed to some extent and then assembled using tools after loading.

[0003]

[Problems to be solved by the device]

 However, when trying to assemble, unless it is a familiar worker, it is necessary to refer to the instruction manual, which is complicated and difficult. In particular, assembling the adjustment mechanism for the floor and the like is heavy, and it is a difficult task to check the assembly position and screw it. The present invention has been made in view of these problems, and an object thereof is to provide a structure for assembling a starting portion such as a floor portion of a bed that is simple and does not require tools.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a bed equipped with a mechanism for adjusting the position of a floor or the like, in which a locking pin having a small diameter portion is attached to the starting portion of the mechanism. An elastic locking member that elastically locks to the small diameter portion of the locking pin is configured to be assembled to the bed main body frame, the floor portion, or the like. Further, the elastic locking member has a ring shape with a part cut away, has an inner diameter smaller than the diameter of the small diameter portion, and has a narrowed portion that allows elastic deformation. . Further, the elastic locking member has a ring shape with a part cut away, has an inner diameter larger than the diameter of the small diameter portion, and has a bent portion that allows elastic deformation, The notch is provided with a locking means for connecting the notch.

[0005]

[Action]

 To attach the activation part to the main frame of the bed, first insert the locking pin into the main frame and lock it. The cutout portion of the elastic locking member is brought into contact with the small diameter portion of the locking pin to push the elastic locking member against the elastic force. Then, the elastic locking member expands and deforms centering on the narrowed portion, and abuts so as to sandwich the small diameter portion. Since the starting part can be attached in this manner, no attachment tool or the like is required. Further, in the structure in which the locking means is provided at the cutout portion, the elastic locking member is engaged with the small diameter portion by connecting the cutout portion with the locking means against the elastic force. Stop and installation is complete.

【Example】

 Next, an assembling structure of a starting portion such as a floor portion of the bed according to the present invention will be described below with reference to the accompanying drawings, with reference to an embodiment. In FIG. 1, reference numeral 1 indicates a starting portion of a mechanism for adjusting the position of a floor or the like. The starting portion 1 has a handle cover 2 in which a gear mechanism (not shown) is incorporated, and an operating rod 3 which can be moved back and forth from the handle cover 2, and is used for operating the gear mechanism in the handle cover 2. It has a crank handle 4. A first locking pin 5 is attached to the handle cover 2, and a small diameter portion 6 is formed near the tip of the first locking pin 5 (see FIG. 2). The first locking pin 5 is to be inserted into a hole 9 of a support piece 8 projecting from a handle receiver 7 provided on the bed body frame. Further, a hole 11 for inserting the second locking pin 10 is provided at a tip end portion of the actuating rod 3 of the starting portion 1, and a driving arm 13 fixedly mounted on a bottom frame 12 of the floor portion. The shaft is fixed through the hole 14 in the. A small diameter portion 15 is formed near the tip of the second locking pin 10 (see FIG. 3).

In the first locking pin 5 and the second locking pin 10 as described above, the elastic locking member 16 is elastically locked to the small diameter portions 6 and 15. The elastic locking member 16 has a ring shape with a part cut away, has an inner diameter smaller than the diameters of the small diameter portions 6 and 15, and has a narrowed portion 17 that elastically allows deformation. Are formed (see Fig. 4).

With the first locking pin 5, the second locking pin 10 and the elastic locking member 16 as described above, the starting part 1 can be attached to the bed main frame or the bottom frame 12 of the floor without tools. . That is, the first locking pin 5 is screwed to both sides of the handle cover 2 and is inserted into the hole 9 of the support piece 8 projecting from the handle receiver 7 provided on the bed body frame, and the supporting piece is attached. The cutout portion of the elastic locking member 16 is brought into contact with the small-diameter portion 6 of the first locking pin 5 protruding from 8 to push the elastic locking member 16 against the elastic force. Then, the elastic locking member 16 expands and deforms around the narrowed portion 17 and locks the small diameter portion 6 so as to sandwich it (see FIG. 5). Since the starting unit 1 can be attached in this manner, no attachment tool or the like is required.

Although the mounting procedure has been described above, an elastic locking member 18 having the following configuration may be applied instead of the elastic locking member 16. That is, as shown in FIG. 6, the elastic locking member 18 has a ring shape with a part cut away, has an inner diameter larger than those of the small diameter portions 6 and 15, and is elastically deformed. And a locking means for connecting the cutout portion, that is, the locking piece 20 and the locking hole 21 are provided.

In the elastic locking member 18, after the small-diameter portions 6 and 15 are fitted in advance, the elastic locking member 18 is pressed from the outside against the elastic force to lock the locking piece 20 in the locking hole. The elastic locking member 18 is locked to the small-diameter portions 6 and 15 by locking and connecting to 21 and the mounting is completed (see FIG. 7).
