Description

DOOR EDGE PROTECTING COVER Field of the Invention

The invention is related to edge protecting cover for doors in areas especially such as hospitals, workplaces, social facilities and hotels.

Particularly, it is regarding door protector in form of cover preventing damages to the edges and frames of the door of public places especially hospitals, medical imaging rooms while sized sick beds and other type of patient handling equipment are carried through doors of the rooms.

Current status of the technique

The invention is related to door protector providing protection for edges and frames of the doors used at especially hospital.

In the current technique, special doors with edge protection and sterile doors are used in areas where high sterile and sterilized conditions are required at hospitals (operation room, laboratory, delivery room, intensive care unit etc.). At the same time, doors of the hospitals are used with door protector.

Big sized and edged handling equipment such as sick beds or necessary equipment for patient intervention are passed through the doors of such rooms.

Especially, sick beds are entered to rooms or exited from rooms swiftly in cases of emergencies.

In such cases, sick beds or intervention equipment may hit or trap edges of the doors. Especially, when patient handling equipment touches to doors or frames of the doors, there might be irreversible damages to the doors or its frames.

Especially, in places where hygiene and sterilization are required, such as hospitals, such kind of damaged, harmed doors can promote bacteria and infection. Meanwhile, damaged door cause serious visual pollution and customer dissatisfaction.

Special door coverings are applied since concerned doors and frames are costly and hard to be repaired and there is a high risk of damage.

In the current condition, the doors are generally made of wood and they are manufactured as fitted on the specific dimensions of the frame. The door dimensions are not standard; therefore, doors such as private hospital doors can be at first installed with monolithic door protectors.

However, door covering is to be replaced by the manufacturer in case of damages and the door is disassembled completely to replace the cover. This results in significant costs.

In other words, door dimensions are measured and coverings are manufactured as 2 separate parts and then applied to door. In these applications, covering is finalized according to surface profile of the door and joined at the surface of latch bolt.

This situation results in serious problems for hygiene, meanwhile there are cases where protective cover is exploded or separated in case of hit of patient intervention equipment or patient handling equipment to the joining points at door edges.

The main problem is the presence of different models and type of door frames. Moreover, covering cannot be manufactured as per door form in the current process; therefore, it is manufactured in two or more pieces as sheet metal and then assembled on the door.

Joining is performed at flat surfaces. In this case, it results in problems described above as well as hygiene and safety problems.

2 protectors manufactured to be joined at flat surfaces are closed by using silicone or similar fillers at joints.

During cleaning, filler materials are eroded in time and this results in disinfection issues. Especially, eroded and damaged joints create areas to promote infections.

In the current applications, sheet metal with different thicknesses are manufactured according to door form as two separate parts and these are assembled onto doors as two or more parts.

In the current technique, there is a compromise in resistance due to not being able to assure complete locking of separate coverings; therefore, covering material cannot demonstrate the same strength everywhere and there might be ejection or explosions on the structure.

As per the current needs, it is compulsory that covering to be used as door protector should be joined evenly and supporting each other everywhere and to be fixated each other.

Door protectors comprising of two or more parts increase factors of man mistakes; thus standard cannot be fulfilled and issues arise.

If surfaces facilitating the protection don't demonstrate same strength, it results in disjoining at low strength areas due to local degenerations. It is of vital importance to assure stabile and homogeneous production, it is required to eliminate issues related to assembly.

Considering the sizes of the door to be assembled, a certain flexibility is desired. This flexibility is provided by using two assembly parts while this brings new problems.

Considering difficulty in application and manufacturing of door protective covers in current techniques, it is necessary to develop simpler, faster and more efficient assembly procedures.

Brief Description of the Invention

Starting from current status of the technique, the main intention is to design door edge protector which can be manufactured as monolithic by easy and standard manufacturing and assembled by use of standard techniques.

Another intent is to increase service life of the coverings furnished for protection. Another intent is to make monolithic door edge protector which has homogeneous mechanical properties.

Another intent is to manufacture as single piece so that to minimize defects related to assembly.

Another intent is to minimize manufacturing costs and expenses by virtue of monolithic manufacturing and standard joining methods.

Another intent is to reduce operation time as compared to current methods; therefore to minimize other costs.

The invention is related to edge protecting cover (1) for room doors (30) in areas especially such as hospitals, workplaces, social facilities and hotels in form of cover preventing damages to the edges and frames of the door (30) of public places while big sized sick beds and other type of patient handling equipment are carried through doors of the rooms.

Door (30) protecting cover (1) being subject to invention is applied to covering surface according to form of the door (30) with all sockets (2) and decorations.

Dimensions of the door (30) to be applied in this regards are measured with all its features. Door (30) lock separation distance, hinge structure and its dimensions and door surface dimensions are measured and it is shaped from sheet metal having desired strength by use of special mold as monolithic in appropriate form and sent for assembly.

Under these conditions, protecting cover (1) having been prepared as per dimensions, are applied onto door (30) covering surface and finalized. Figure - 1 illustrates perspective view of a desired application of door edge protecting cover (1). Given figure is representation and it is made suitable for all door (30) models

The said protecting cover (1) comprises of at least one midsection surface (20), the said mid section surface (20) as monolithic and two side surfaces (10) to create U form according form of the door (30).

The said side surfaces (10) covers door (32) side surfaces and midsection surface (20) covers middle area (31).

In this condition, middle surface (20) is formed according to door midsection area (32). Side surfaces (10) are dimensioned according to intended side areas (31).

Moreover, the related covering can be applied to back sides of the doors which have similar characteristics.

In Figure 8 and 4, in a desired application, protecting cover (1) side surface (20) has additional decorations (21). These decorations (21) are shaped according to door midsection surface (32). It includes flat or decorated (21) midsection surface (20).

It has locking mechanisms and sockets available on middle surface (20) middle areas (32). It has sockets according to hinges or fire preventive areas at back side.

All sockets (2) are created on two side faces (10) and midsection surface (20) in the simplest form to create U form.

Protecting cover formed as per door (30) form and dimensions to cover side surface (31) and midsection areas (32) and assembled as monolithic part. To facilitate complete adherence in assembly, currently known adhesives are used.

In any case, the structure is monolithic and a whole body, gripping is provided at desired level, it is harmed at minimum level during passage of patient handling equipment or treatment devices. The risk of ejection or separation is minimized since it does not have a joints.

Door (30) protecting cover (1) subject to claims is differentiated from current designs by manufacturing mold and sheet metal properties.

As a result of the studies conducted, sheet metal is specifically used. Apart from the currently used materials, sheet metal has 1 mm or less, or, 0,3 mm or more thickness.

The thickness of the door (30) protective cover (1) subject to claims is; lmm < Metal Thk >0,3

The sheet metal having this thickness is shaped by use of a mold thinner than 3 mm.

The mold thickness used for the said protecting cover (1) is;

0 < Mold Thk >3mm

The mold thickness is determined proportional to sheet metal thickness within 0 < Mold Thk > 0.3. In any case, protecting cover (1) subject to claims is shaped according to sheet metal thickness within lmm < Metal Thk >0,33 range by a mold having thickness within 0 < Mold Thk > 3 mm range as per door (30) form by facilitating decorations and folds.

Without any part, it is provided as per door (30) form in a single piece. Moreover, the thickness of the sheet metal is determined considering door (30) separations and in a way not to impede movements.

As a result of studies and trials conducted, it is observed that protecting cover (1) subject to claims found compatible with all doors provided that thickness is within lmm < Metal Thk >0,3 range. In this stage, it is observed that it can be shaped by a mold within 0 < Mold thk > 3 mm thickness range proportional to the thickness of the material within the range of lmm < Metal Thk >0,3 and implemented in this manner. The door (30) to be applied is shaped from sheet metal which is compatible with its dimensions by mold with appropriate thickness and range as a single part.

The thicker the sheet metal is, the thicker the mold is used within given ranges. Protecting cover (1) obtained from sheet metal forming at miscellaneous or requested quality is offered by single joining operation with appropriate adhesives applied onto door (30) covering surfaces which will be performed according to definite process steps.
