Description

Technical field

The technical solution relates to a folding siderail, in particular to a positioning bed, formed by support posts connected rotationally to the sides of the bed and horizontal fillings located between the supporting posts.

Background Art

Hospital positioning beds often use folding and tilting siderails to prevent unwanted patient falling from the bed.

Tilting sides are usually attached to both sides of the bed to the supporting frame structure of the bed. The main disadvantage of folding siderails is their tilting trajectory, which, when filling the entire side of the bed, extends beyond the ground plan of the bed and very often collides with eg impact wheels. Therefore, the folding siderails are most often mounted only on the side of the mattress platform and the free space is used to cover the siderail trajectory during tilting. The disadvantage of this solution is the opening of it more often in the foot part of the bed, which increases the risk of the patient falling from the bed.

The folding siderails are used both for beds with a load-bearing frame structure and for beds with a loading surface that is self-supporting. In the case of bed frame structures, one-piece hinged siderails are most commonly used to protect the patient from undesirable falls over the entire length of the bed. Their disadvantage is again the tilt path. Sufficient space on both sides of the bed is necessary to lift the siderail, and the caution of the operating personnel is to prevent damage to the surrounding objects or even bodily injury when tilting. In the case of confined spaces, it is not possible to fold the siderail at all. For beds with a self-supporting bedding structure, split hinged sides are often used, which are attached to individual parts of the mattress platform, most often to the back and calf parts. However, this solution has the same drawbacks as the one-piece hinged siderails, with the difference that the split siderails create an opening between the siderails themselves. This opening is often very risky with the risk of pinching and wedging the patient.

The essence of the technical solution

The aforementioned drawbacks are largely eliminated by the collapsible siderail, especially for the positioning bed, formed by support posts connected rotationally to the sides of the bed and by horizontal fillings disposed between the supporting posts, according to this technical solution. The essence of this is that the panels are connected to the posts by means of joints and are telescopic, wherein at least one support post is provided with stops in both directions of movement and the posts are interconnected by a stiffener.

The upper filling is preferably provided with an extension for placing it, above the upper edges of the bed ends, when the siderail is raised.

The folding siderail according to the present invention is also attached to the outer edge of the bed frame frame. The main siderail pillars are pivotally attached to the bed frame as close as possible to the head and foot faces of the bed so that there is no risk of pinching or wedging in the space between the bed ends and the siderail pillars. The lateral posts of the siderails are connected by means of joints to horizontal fillings of any cross-sections, such as tubes, needles, flat ovals, etc. The basis of the technical solution is the mutual telescopic interconnection of horizontal fillings of both outer posts with sufficient mutual insertion of opposite horizontal fillings in the basic upright position of the siderails. The range of movement of the siderails is limited by stops on both sides. In the initial vertical position, the posts are locked by the locking mechanism. After unlocking the locking mechanism, the two siderails can be folded down

-1GB 22251 Ul towards the center of the bed. For uniform direction and tipping speed, the side pillars are interconnected by a stiffener to ensure synchronous movement of the two pillars. When folding the siderails, the two outer pillars act in a synchronous motion toward the center axis of the bed and their horizontal fillers telescopically slide into one another. The lower post position is defined by a stop.

The uniqueness of this solution is the utilization of the most simple mechanical principle of synchronous tilting of the side pillars of the siderails together with telescopic retracting. ejecting horizontal siderails.

One of the greatest advantages of the folding siderails in this technical solution is that the siderail path does not interfere with the contour of the bed while folding and does not restrict the operator or patient on the bed. Another significant benefit is the ability of the designed siderails to cover the entire length of the bed's loading area with minimal risk of pinching or wedging the patient between the siderail posts and the bedside. An indispensable advantage of this technical solution is the interconnection of the siderail pillars with a cradle, thanks to which it is sufficient to fit only one of the pillars with the locking mechanism and the user can control the siderail from one central point where the arresting mechanism is fitted. This central point may be any extreme shell of the siderail. Another advantage of this design is the possibility of radically increasing the upper edge of the siderails above the loading surface or the top of the siderail. over the mattress. This increase can be achieved by trivial adjustment of the edge posts and horizontal siderails.

Explanation of the drawings in the drawing

The collapsible siderails of the present invention will be explained in more detail with reference to the accompanying drawing. FIG. 1, the positioning bed is shown in side view with the folding sideboard in the upper position. FIG. 2 in the intermediate position and FIG. 3 in its lower position.

Example of a technical solution

Exemplary collapsible siderails for positioning beds formed by support posts 1 connected rotatably to the sides 8 of the bed and horizontal fillers 10 positioned between the support posts I. The panels 10 are connected to the posts 1 by means of joints 3. The panels 10 are telescopic. At least one support post 1 is provided with stops 2 in both directions of travel. The posts 1 are interconnected with a yoke 9. The upper packing W is provided with a JT extension. The folding siderail is attached to the outer edge of the bed mattress frame. The main side pillars 1 are pivotally attached to the bed frame as close as possible to the head and foot faces of the bed so that there is no risk of pinching or wedging the patient between the bed ends and the side pillars. The side columns 1 of the siderail are connected by means of joints 3 to horizontal fillings 10.

In the basic upright position of the siderails, the horizontal fillings 10 of the two outer pillars are placed with sufficient mutual insertion of the opposite horizontal fillings 10 of the outer fillings 4, 5 and the inner fillings 6, 7. the default vertical position, the posts 1 are locked by the locking mechanism. After unlocking the locking mechanism, both side rails 1 can be folded toward the center of the bed. For uniform direction and speed of folding, the outer pillars are interconnected by a carriage 9 which ensures the synchronous movement of the two pillars. The lower position of the posts 1 is again defined by the stop 2.

To allow the top panel to be positioned as high as possible, it is attached to the posts 1 using the JT extension,
