Definitions
- the invention relates to a cleaning device for cleaning a running escalator.
- cleaning an escalator has mostly been done by hand. This takes a considerable amount of time.
- Most escalators are already connected to a collection container at the hidden deflection points, but only the loose particles and dust lying on the steps fall into them.
- modern escalators are usually provided with grooves that run perpendicular to the width of the standing surface, in which dirt easily settles that does not fall out of the grooves at the deflection points.
- this also means a running ramp or a running footbridge.
- the structure of the ramp or the bridge corresponds to that of the stairs, in that only those elements that make up the individual steps are designed differently, are guided along less steep or horizontally arranged rails and are redirected at the ends as in the escalator the.
- the invention has set itself the task of creating a simple and inexpensive device that makes use of the movement of the stairs themselves and can therefore do without external energy.
- the prerequisite for this is that the stairs move.
- the device shown in Figures 1-3 has a frame which consists of a solid plate 1 with an arm 2 welded to it in the form of a square tube.
- An axis 3 is attached to the front of the plate 1 and is provided with transport rollers 31 at its ends.
- a U-shaped receptacle 11 for a brush 4 is attached under the plate 1.
- a dust suction channel 12 Connected to and in the operating position behind the receptacle 11 is a dust suction channel 12, which is provided with a connection pipe 13 for a vacuum cleaner hose. If “above” and “below” or “behind” is mentioned here, this refers to the operating position of the cleaning device as shown in FIGS. 1 and 2.
- a V-shaped flat iron bracket 5 is welded onto the top (in the operating position) of the plate 1 and carries a self-adjusting transport roller 51.
- the actual cleaning brush 4 is held in the receptacle 11 and fastened by means of two wing nuts 41, so that it can be easily removed and replaced by loosening the nuts.
- the brush will be described in detail later.
- the arm 2 is provided with three bores, which are lined with short pipe sections 21. These pipe sections are firmly attached to the arm. They lie approximately in the plane of the plate 1 and run perpendicular to the arm 2. The outermost tube section in FIG. 1 is protected on both sides. This protection 22 serves as a handle during transport. On the underside of the arm a pin 23 is attached which ensures an approximately horizontal operating position of the device.
- a holding clamp 24 is attached to the top of the arm 2 approximately above the pin 23.
- the brush 4 already mentioned has a half of hard bristles 42 which loosen the dirt and a second row of softer bristles which sweep up the loosened dirt and dust, which can then finally be sucked off from the suction channel.
- the hard bristles can be made of stainless steel, for example, and the softer ones of nylon.
- the cleaning device is shown in the operating position on an escalator.
- the cheeks of the stairs are indicated by W on which the handrail H moves synchronously with the stairs.
- U is a fixed, non-moving transition part to the stairs under which the steps S1-S3 slide out.
- the stairs should run during the cleaning process.
- the cleaning device is during operation by a rod 6 which is inserted through one of the pipe sections 21, held.
- the rod 6 is supported on both sides of the head of a fixed part of the stair stringers W.
- the bar consists of telescopically slidable parts so that its length can be adjusted to the width of the stairs.
- the cleaning is ongoing.
- the brush 4 has cleaned the level S3 and is now on the level S2. It is clear that the entire staircase can be cleaned in this way, but also that the entire length of the staircase can be run several times along the cleaning device if it is very dirty.
- FIG. 3 shows the position of the cleaning device during transport.
- the device rests on the three rollers 31, 51 and can easily be moved to or removed from the cleaning point.
- the uppermost pipe section 21 serves as a handle and the self-adjusting roller 51 allows easy maneuvering.
- the rod 6 is now completely pushed together and is held in the holding clamp 24.
- the other end of the rod is inserted through a bore 52 provided in the bracket 5.
- the brush 4 is removed from the receptacle 11 by loosening the wing nuts 41 and cleaned. A swiveling of the bristles in a cleaning liquid is usually sufficient.
