Description

Side rail for medical bed with damper {SIDE RAIL FOR MEDICAL BED WITH DAMPER}

The present invention relates to a side rail of a medical bed, and more particularly, to a side rail of a medical bed that is provided with a damper to reduce impact when the side rail is operated.

In general, a medical bed serves to provide a space for users and patients to lie down to rest or receive treatment, and to accommodate patients who require long-term treatment or have limited activities, such as in general rooms or intensive care units of hospitals. It is provided and used.

These medical beds have side rails having a certain height on both sides of the medical bed, that is, on both sides of the main frame installed on the medical bed located on both sides of the patient lying on the medical bed in order to prevent a fall accident by the patient lying down from the bed. It is being installed.

Patent Document 1 (the name of the invention: the side rail of the medical bed and its manufacturing method) as a prior art related to the side rail of a medical bed includes a plurality of rotating frames that are rotatably installed between the upper frame, the lower frame, the upper frame and the lower frame. , A configuration including a standing device for maintaining and releasing a standing state of the rotating frame is disclosed.

In addition, Patent Document 2 (name of the invention: side rail of a medical bed) includes a plurality of support rods rotatably installed between the upper frame, lower frame, upper frame and lower frame, and a hinge that reduces the lowering speed of the upper frame when the support rod is rotated. A configuration including a bracket is disclosed.

In addition to the side rails of medical beds disclosed in Patent Documents 1 and 2, the side rails of most conventional medical beds are all bound in a pin-type riveted form when a rotating frame or support rod is coupled to the upper frame (lower frame). It was common.

This pin type (rivet coupling) has a problem in that the binding force to the upper frame (lower frame) of the rotating frame or the support bar is not constant depending on the usage period.

In the case of a new product that has not been used for a long time, the pin type (rivet combination) is excessively fastened. On the other hand, in the case of a product with a long use period, the rivet bond is loose and its bonding strength is insufficient.

If the binding force is excessive, a lot of force is required when the user rotates the rotating frame or support bar, and for this reason, there is a problem that a strong impact occurs when the upper frame comes down and the support bars touch each other, or when the upper frame or hinge bracket touches the support bar. have.

When the binding force is insufficient, a lot of force is not required when the user rotates the rotation frame or the support bar, but there is a problem that the upper frame descends and generates an impact even when the user does not intend.

The problem caused by such a binding force is that the device is damaged, as well as the risk of injury when the user's hand is caught, causing secondary damage.

Next, looking at the coupling relationship between the lower frame 200, the fitting unit 600, and the hinge bracket 700 with reference to FIGS. 14 to 16, they have the same coupling relationship as in FIGS. 11 to 13, Since it is a coupling relationship with the lower frame 200 located below the frame 100, the vertical direction has a symmetrical coupling relationship. Accordingly, for the convenience of understanding, in FIGS. 14 to 16, the symbol of the fitting unit coupled to the lower frame 200 is 600, the symbol of the hinge bracket is indicated as 700, and the fitting unit 600 and the hinge bracket ( 700) are also marked accordingly.

In addition, the side rail of the medical bed having a damper according to the present invention may be configured to include an operation lever unit 800 installed below one end of the upper frame 100 as shown in FIGS. 1 and 2. have.

The operation lever part 800 includes a casing 810 installed below one end of the upper frame 100; A spring (not shown) installed inside the casing 810; And a lever 820 that elastically operates by a spring.

The user may operate the side rail to stand up and release to stand up by operating the operation lever unit 800.

3 and 4 are perspective views of a damper according to the present invention. Referring to FIGS. 3 and 4, a side rail of a medical bed having a damper according to the present invention may include a damper 900.
