Description

DESCRIPTION

Door with door hardware and mounting procedure for the same

The invention relates to a door with a door fitting, a door-fitting combination and an assembly method therefor.

A door of this type is known by the following bibliographic reference:

[1] Company brochure "Stahltüren" (steel doors) of Hormann KG Verkaufsgesellschaft with the print indication "Stand 04.2019 / Druck xx.2019 / HF 85115 DE / G.xxx www.hoermann.com", downloaded from the Internet on 27.08.2019.

From [2] IT TO20130390 A1, doors in the form of a left-hand and right-hand stop door, as well as a sliding door with a door leaf in the wall and a sliding door with a door leaf outside the wall, and a door leaf that can be used for all of these door types, are known. The door leaf has a seat for a lock in the lock area, with passage holes for a key and a latch. The passage openings can be closed by means of covers or gripping elements.

From [3] US 5722 203 A a door is known with a frame and a door leaf hinged to it by means of door hinges. The door leaf is equipped in the lock area with a clearance hole for mounting a door handle similar to that found on American interior doors. For mounting the door leaf, a mounting aid is provided, which can be inserted into the clearance hole and which locks the door leaf in the closed state during mounting.

From [4] US 2002/0043293 A1 a device for producing door leaves with a computer-aided drilling device is known. Menu-guided settings can be made on a control to produce different fixing devices for different door fittings.

Fire doors and other protective doors are frequently required for use in various buildings. According to safety regulations, these types of security doors require approval from the building authority. This is granted after a verification of the protective function.

When testing the protective function, not only the basic door structures, such as the door leaf and frame, are relevant; door hardware can also influence the protective function. For example, doors can be tested and also delivered with standard hardware. In this way, the door manufacturer ensures that the protective function is fulfilled. However, other door hardware is often desired, such as special door handles with corresponding strike plates or lock plates or special rosettes. Until now, the door has often been delivered without hardware, and the final hardware selected by the customer has been fitted to the door at the assembly site. This carries the risk of incorrect assembly or the installation of unsuitable door hardware, thus negatively influencing or impeding the protective function.

The invention aims to provide a door, specifically a protective door, that can be individually adapted to local conditions in a simpler and, at the same time, more secure manner. In particular, the manufacturer must ensure that individual adaptation with simple assembly is possible while still ensuring the protective function of the door.

To achieve this objective, the invention provides a door according to claim 1. A door-fitting combination is specified in dependent claims 7 and 8. A method for assembling such a door is specified in claim 9. Advantageous embodiments are the subject of the subclaims.

According to one aspect thereof, the invention provides a door comprising a door leaf and an auxiliary fitting mounted on the door leaf in through-holes, preferably having a latch and a fitting plate, the door leaf having, in addition to the through-holes, a prefabricated fastening device for a door fitting which is to be fixed at the assembly location instead of the auxiliary fitting.

According to the invention, the auxiliary fitting is a standard fitting. In this way, the manufacturer ensures that the door already fulfills all door functions that can be influenced by a fitting upon delivery. This can also include, for example, continuous operation, which can be certified by a long-term test with several thousand door movement cycles.

Prefabricating the fixing device for a door fitting to be installed at the assembly site has the primary advantage that an installer can easily assemble the individual door fittings themselves, for example, without having to first measure and fully lay out the fixing holes. Through prefabrication, the manufacturer directly specifies the correct assembly, thereby avoiding incorrect assembly and the resulting negative impact on the door's quality. Furthermore, the manufacturer can influence the selection of door fittings by specifying one of several possible fixing devices that fit one or more door fittings, thereby ensuring that only suitable and appropriate door fittings are used.

It is preferred that the fixing device has at least one or more blind holes for screw fixing of the door fitting.

If necessary, the assembler can easily drill blind holes on site or use them directly for mounting.

It is preferred that the door leaf be at least 40 mm thick and that at least one knockout have a depth of at most 15 mm, preferably 10 mm. This ensures that the knockouts do not affect door functions requiring a continuous barrier at door leaf level, such as a fire protection function or smoke protection function.

It is preferred that the fastening device has a hole pattern produced according to predetermined data for a predetermined door fitting. The data for corresponding fixing hole patterns for different door fittings, which are suitable for the door and are supplied, for example, by third parties, can be stored or received and input industrially, for example, through computer-aided machining.

The provision of blind holes also has the advantage that the customer will only select hardware that matches the blind hole pattern, as exposed blind holes would represent an optical construction defect.

Preferably, the door is configured as a protective door from the group of protective doors comprising a fire door, a burglar-proof door, a smoke protection door, a soundproof door, a bullet-resistant door, a radiation protection door, as well as combinations thereof.

According to another aspect, the invention relates to a door-fitting combination, comprising a door according to one of the preceding claims and the door fitting, the prefabricated fixing device being adapted to an arrangement of fixing elements of the door fitting.

It is preferred that the door fitting has a fitting plate with openings for screws or fixing projections as fixing elements and that the door leaf has blind holes arranged appropriately for this purpose.

The door hardware is preferably a handle set or has one. Consequently, the auxiliary hardware is preferably an auxiliary handle set, such as a standard handle set, or has one.

To manufacture the door according to one of the aforementioned embodiments, a manufacturing device can be used, which comprises a door leaf manufacturing device for manufacturing the door leaf and a computer-aided drilling device with at least one drill that can be positioned by a control, the drilling device being configured to receive data for the arrangement of fastening elements of a door fitting and to introduce blind holes in the door leaf corresponding to this arrangement.

According to another aspect, the invention relates to a method for assembling a door with a door fitting selected according to the customer's wishes at an assembly site, comprising the steps:

a) manufacture the door according to one of the above configurations with the fixing device adapted to the selected door fitting,

b) deliver the door with the auxiliary hardware to the assembly site,

c) remove the auxiliary hardware,

d) make the door hardware available at the assembly site and mount it on the door,

e) door installation.

In this regard, the stages are indicated with a) to e) for better reference only, this is not intended to imply any specific order of the stages.

Embodiments of the invention relate to a pre-equipment of hardware for a door, in particular a protective door, more particularly a fire door.

In practice today, doors with high-quality hardware are only pre-equipped, i.e., the necessary hole pattern is milled into the door leaf. However, they are delivered without the actual hardware. This is then delivered by third parties and installed. However, it is desirable for fire doors to be delivered only in working order. To achieve this, the door manufacturer would have to employ larger storage/logistics facilities in order to be able to supply customers with individual hardware tailored to their needs. Instead, in embodiments of the invention, a simple and therefore cost-effective standard hardware is attached or included. The holes required for the high-quality hardware are only indicated on both sides (drilling depth: e.g., approx. 10 mm). The final installer can then simply complete the hardware holes and install the more complex/higher-quality door hardware, also supplied by a third party.

It has been proven that 10 mm deep holes do not have a significant impact on performance characteristics. This allows a door manufacturer to adapt the delivery state to the required performance characteristics later.

Below, an example implementation is explained in more detail with reference to the accompanying drawings. They show:

An exemplary embodiment of a door 10 in the form of a protective door, specifically a fire door, will be explained in more detail below with reference to the figures. In this regard, Figs. 1 to 4 show the door 10 with a frame 12 and a door leaf 14 pivotally attached thereto.

An auxiliary fitting 16 in the form of a standard handle set 18 is mounted on the door leaf 14.

Figures 5 to 7 show the door leaf 14 without the standard handle set 18.

The frame 12 is a metal frame with several frame stringers 20, which are formed by metal profiles and as described and shown, for example, in the bibliographic reference [1], pp. 30 and 31.

The door leaf 14 is specifically designed as a box-lid sheet metal construction made of sheet steel. Examples of such door leaves 14 can also be found in the reference [1]. The door leaf 14 has a filler 22 comprising a firmer filler material 26 surrounding a lock case 24. A lock 28 is arranged in the lock case 24. Examples of the filler material 26 and further details of possible configurations of the door leaf 14 are described and shown in [1], and for further details, reference is made specifically to [1].

The standard handle set 18 is, for example, of the type described and shown on page 32 of the bibliographic reference [1]. The standard handle set 18 has a latch 30 and first and second fitting plates 32a and 32b. The first and second fitting plates 32a, 32b are secured with first and second through-hole screws 34a, 34b, which are guided through the door leaf via first and second through-holes 36a, 36b.

As can also be seen from Figs. 5 to 7 and Figs. 2 to 3, the door leaf 14 has a prefabricated fastening device 38 for a door fitting 60, which is to be fastened at the installation location of the door 10 instead of the auxiliary fitting 16, an example of which is shown in Fig. 4 by dash-dotted lines.

The door fitting 60 may be a door fitting from a group of door fittings approved by the manufacturer of the door 10. For example, the door fitting is an anti-panic fitting with a bracket extending transversely across the door leaf 14 as a handle or a high-quality handle set with a larger fitting plate or the like.

When ordering the door 10, the manufacturer of the door 10 orders the door fitting 60 and enters data for the production of the adapted fastening device into a manufacturing device for the door 10. The manufacturing device (not shown) is a conventional manufacturing device for this type of doors 10 with a computer-aided drilling device having at least one drill controlled in correspondence with these data.

The data contain in particular a hole pattern or a drilling pattern 39 for clearance holes to be made in the door leaf 14 for fixing the door fitting 60 by means of clearance screws 34a, 34b. In the example shown in the figures, clearance holes are to be inserted at a first to fourth location 40a-40d, which then correspond to fixing openings 62 (example of a fixing element) of the door fitting 60.

However, at the door manufacturer's plant, the drilling device of the manufacturing device does not produce clearance holes for the door fitting 60, but only blind holes 42a-42d. Accordingly, in the exemplary embodiment shown, the fastening device 38 contains a first to fourth blind hole 42a-42d, which are inserted into the door leaf 14 with a maximum depth of 5 to 15 mm, preferably 10 mm, from the door leaf widths 44a, 44b. In one configuration, only one blind hole 42a-42d is inserted per location 40a-40d from one side. The figures show a preferred configuration, in which one blind hole 42a-42d is inserted per location 40a-40d from each door leaf width.

Thus, the door 10 is manufactured industrially in large series, with the prefabricated fastening device 38 for the desired door fitting 60 also being manufactured in large series and thus reliably. However, to ensure full functionality in the delivered state, without having to stock or purchase the door fitting 60 from the manufacturer, the door 10 is provided with the auxiliary fitting 16.

At least one sample of the door 10 shown in Figs. 1 to 4 is tested for all the functions to be fulfilled. In particular, a fire test is performed with the auxiliary fitting 16. This confirms that the door 10 fulfills the required function. A test, simulation, or calculation is also performed with possible door fittings to select only those door fittings that do not negatively influence the required function. The fixing device 38 is prefabricated only for appropriately selected door fittings and is therefore only adapted to door fittings for which the function can also be guaranteed.

The door 10 is then manufactured as shown in Figs. 1 to 4 and delivered to the assembly site. The door fitting 60 is also made available at the assembly site, either by the manufacturer of the door 10 or by a third party. At the assembly site, the assembler assembles the frame 10 and the door leaf 14, removes the auxiliary fitting 16, completes the clearance holes at locations 40a-40d by drilling the blind holes 42a-42d, and mounts the door fitting 60 thereon.
