DE202007003739U1 - Authorized door opener consists of radio-controlled fire or smoke detector and door opening mechanism, and supplies power to public power authorities without connection, where information exchange take place wirelessly between components - Google Patents

Abstract

The authorized door opener consists of two components, which are a radio-controlled fire or smoke detector and a door opening mechanism respectively. The exchange of information takes place wirelessly between both the components with the existing radio link. The authorized door opener supplies power to the public power authorities without a connection.

Description

1. The problem:

• a) verbotener Holzkeil Im Brandfall schließt die Tür nun nicht mehr. Die Tür erfüllt ihre Zweckbestimmung nicht mehr.
• b) zugelassene Systeme an der Oberseite der Tür Grundsätzlich sind zwei Systeme bekannt – Magnethaltesystem, Schienenhaltesystem. Nach DIN benötigt man einen/mehrere Rauchmelder, die die Schließelektronik im Rauchfall auslösen. Die Schließelektronik muss dauerhaft über die örtliche Energieversorgung mit Strom versorgt sein. Dazu benötigt man eine Verkabelung an der Tür. Die beschriebenen Standard-Installationstechniken sind durch nachträgliche Aufputz Installation bzw. der Beschädigungen der Brandschutztür aufwendig, teuer und oft optisch unattraktiv.

There is a fire door planned or already in place, now the door user (reasons: convenience, marketing) notes that this door should be kept open. Fire doors are usually provided due to the necessary smoke tightness with a mechanical spring closure. Ie a fire door does not remain open by itself, it closes independently. In order to keep the door open it is necessary to retrofit with a "hold-open system." What does this retrofit of conventional design look like (actual situation)?

• a) Prohibited wooden wedge In case of fire the door will not close anymore. The door no longer fulfills its purpose.
• b) approved systems at the top of the door Basically, two systems are known - magnetic holding system, rail holding system. According to DIN, one or more smoke detectors are required to trigger the closing electronics in the event of smoke. The locking electronics must be permanently powered by the local power supply. This requires a wiring on the door. The standard installation techniques described are complicated by subsequent surface installation or damage to the fire door, expensive and often visually unattractive.

2nd recombination existing technology

By to offer the new developments of radio-controlled fire alarm systems many new possibilities for the wireless installation. Show new developments in the field of mobile telephony also the tendency to smaller and more efficient ones Battery.

3. Description

The Idea refers to the replacement of a cultural-historical most used Door wedge. The invention is intended to the above-described disadvantages of the known Door Dwell Solve systems. The system is referred to in the following with fire protection wedge.

Of the Fire protection wedge consists of a body behind any type of construction a door can be arranged. This body will be at the desired position behind the door attached to the ground. Can do this various fastening systems (mechanical or chemical fastening techniques, Vacuum techniques, etc.) can be used.

At this body is rotatably attached a hook. A round metal bar is on one End bent at 90 ° to the hook after the rebate depth and width of the door. After this 90 ° bend an assembly is mounted, which serves the friction resistance when loosening reduce the hook and prevent damage to the door. This assembly is one in the same diameter as the round metal rod in the central axis of the round rod rotatable unit (e.g., ball bearings).

Of the Wireless smoke detector is installed in accordance with DIN above the door. At the smoke detector is from a commercial one approved radio smoke detector. This one is independent of the local Energy provider operated (for example, battery). It consists of two units, the smoke detector and the radio transmitter. This sends on the same Frequency like the radio receiver, which is located in the fire protection wedge.

Of the described hook of the fire protection wedge is placed in a position in which he the fire door keeps open in its fold. In this position, the hook can only remain when the electronic Control of the fire protection wedge is sufficiently energized. This can be ensured by appropriate electronics or mechanics.

smoke detector and fire protection wedge are turned on. From this point gets the radio receiver the fire protection wedge a regular OK signal the radio transmitter of the smoke detector if no smoke was detected and the battery power is sufficient. Otherwise it stays that way Signal off and the fire wedge triggers. A mechanics inside of the fire protection wedge causes the hook at an angle of turns at least 100 °. The door is now no longer held and can by its upper door closer into the Lock fall.

Of the Fire protection wedge triggers Also off when the electronic controller detects that they are no longer with sufficient current, caused by discharge battery or system failure.

Claims (9)

The approved door opener without connection to the public utility is characterized in that it consists of two components. On the one hand, this is a radio-controlled fire or smoke detector and, on the other hand, a door-open device (hereinafter referred to as a fire-protection wedge). Between the two components, the information exchange is wireless, there is a radio connection. Door open holders according to claim 1, characterized in that it is in its shape only so big that he's on the floor behind every door can be mounted. Door open holders according to one of the preceding claims, characterized that he simply, without structural changes by means of mechanical (e.g., screws), or chemical attachment techniques (e.g., adhesive), or vacuum techniques etc. can be attached to the ground. Door open holders according to one of the preceding claims, characterized that he without connection to the public Energy supplier is operated. He has his own energy source. That could be rechargeable batteries according to the current state. Door open holders according to one of the preceding claims, characterized that he is using a radio receiver equipped, which signals from the listed under 1. Fire / smoke detector can receive.
