Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a fall prevention device for a child's bed or the like.

(Prior Art) As a conventional fall prevention device for a bed for children, there is one shown in FIG. 5, for example. The robot is moved up and down along a guide rail e provided at d.

In addition, as other conventional examples, for example,
As disclosed in Japanese Patent No. 59137, there is also one in which the vertical bar a is configured to be extendable and retractable.

(Problem to be solved by the invention) In the former case where the entire fence body c is raised and lowered, if an attempt is made to obtain a sufficient vertical width in the raised state, the upper end of the fence body c will be raised and lowered in the lowered state. There is a problem in that the height of the floor f has to be increased in order to prevent it from getting in the way.

Although the latter solves these problems to a certain extent, it has the problem of increased manufacturing costs.

The purpose of this invention is to solve the above problem.

(Means for Solving the Problems) Means for solving the above-mentioned problems will be explained with reference to drawings corresponding to embodiments. 1a, 1b, 1c, 1d, . . . ) are successively intertwined with each other for each adjacent member, and adjacent pairs P ₁ (1a, 1b), P ₂ (1c, 1d), .
In the wide state, the rails are connected at least at one end (joint part 2) to form the fence body 3, and one opposing side is opened (opening 4) on both sides of the bed B. A pair of guide frames 5 are provided upright, and both sides of a support bar member 6 are fitted into the guide frames 5 so as to be able to rise and fall freely, and the support bar member 6 can be freely supported in the raised position by an engagement mechanism S. The coiled elastic member 1a forming the upper end of the fence main body 3 is fixed to the support beam member 6, and the coiled elastic member 1z forming the lower end of the fence main body 3 is rotated downward on the side of the bed B. While fixing to the freely supported winding member 7,
The winding member 7 is biased by a spring in the rotating direction for winding up the fence body 3, and both ends of the coiled elastic member 1 are positioned within the guide frame 5.

(Function) In the above configuration, the fence body 3 can be wound up on the winding member 7 since the adjacent pair P ₁ , P ₂ , . . . can be brought into a mutually bent state. Dimensions can be shortened. Therefore, this rolled-up state can be used as a stored state.

When the support bar member 6 is raised along the guide frame 5, the fence body 3 is released from the winding member 7 against the bias of the spring and rises, so that the support bar member 6 is moved up by the engagement mechanism S. It can be put into use by supporting it in the raised position. In this state, the coiled elastic member 1 at the intermediate position is prevented from coming off from the guide frame 5 by both ends positioned within the guide frame 5.

In such a state of use, in order to prevent the fence body 3 from moving further upwards, the winding member 7 is made unrotatable in this state, or when this state is at the end of the movement stroke of the fence body 3. It is configured in advance so that it is a section.

If a child or the like collides with the shelf main body 3 under the above usage conditions, the shelf main body 3 will be elastically deformed due to the extension of the coiled elastic member 1 and will elastically receive the body, thereby preventing injury. It can be prevented.

Next, when the support by the engagement mechanism S is released and the support beam member 6 is lowered along the guide frame 5, the winding member 7 rotates due to the bias of the spring, and the lowering fence body 3 is rotated. It can be rolled up and thus put into storage as described above.

Since the fence main body 3 is thus wound up on the winding member 7 to be in the stored state, the lifting stroke of the support beam member 6 can be increased even if the minimum height of the support beam member 6 is lowered.

Even when the fence main body 3 is repeatedly expanded and contracted as described above, each adjacent pair of coiled elastic members 1 is connected at least at the connecting portion 2 at one end. In the case of independence, it is possible to prevent axial dislocation that would otherwise occur due to relative movement.

(Embodiment) Next, an embodiment of the present invention will be described. The illustrated support member 3 has a wrapping portion 9 in which an opening 8 having a width narrower than the outer shape of the coiled elastic member 1a is formed on the lower side. The core rod 10 is fitted into the coiled elastic member 1a inserted into the holding portion 9, and the coiled elastic member 1a is fixed to the support beam member 6. In addition to this configuration, the coiled elastic member 1a may be fixed to the support beam member 6 in any appropriate manner.
Also, a coiled elastic member 1z forming the lower end of the fence body 3
The method of fixing the winding member 7 to the winding member 7 is also suitable.

As mentioned above, the winding member 7 rotates under the bias of a spring to wind up the fence body 3 fixed thereto, and its structure is such that a rotatably fixed rod-shaped body is rotated by a spring or low torque. It can be configured as appropriate by applying pressure using a spring (not shown) such as a spring.

Next, the illustrated engagement mechanism S includes an engagement portion 13 installed at an upper position within the guide frame 5, and a lever mechanism 14 installed on the support beam member 6 and capable of engaging and disengaging the engagement portion 13. These configurations are also suitable.

Furthermore, although the illustrated coiled elastic member 1 has a single-thread configuration, it can also have a multi-thread configuration.

(Effects of the invention) As described above, the present invention basically consists of a structure in which a large number of large pitch coil-shaped elastic members are successively intertwined and connected with each other for each adjacent member, and this is attached below the bed. Since the winding member is rotatably supported and can be wound up by the bias of a spring, when in use, the upper end is raised by the support member and supported in a wide state, thereby preventing children, etc. from falling on the bed. In addition, since the width is narrow in the retracted state, the lowering position of the support beam member is low, and the floor height of the bed is configured low, making it easy for children to get on and off the bed and to make the bed. There is an effect that there is.

Since the present invention has the above-mentioned structure of the side fence body, it is able to elastically deform when a body collides with the body, thereby alleviating the impact and preventing injury. This has the advantage of being easier to manufacture, lower in cost, and more durable than a flexible structure.
