Description

The invention relates to a connection device for connection to a working space.

Under working space is understood in the context of the invention, in particular a contaminated area. For example, the invention is directed to work rooms in which asbestos-containing material is degraded. The invention can also be used where the air is to be cleaned in a working space.

The degradation of asbestos-containing material requires particularly high safety measures from a health point of view. Some asbestos particles are sometimes only a few microns in size and so light that they float and easily enter the lungs of humans, which can lead to a high health risk. With water, however, the asbestos particles can be well bound and thus washed off.

Areas contaminated with asbestos must always be kept under negative pressure during refurbishment work in order to prevent the asbestos from escaping from the contaminated area during dismantling.

In practice, asbestos-contaminated workspaces are connected to personal locks through which persons who carry out work measures in the work space enter and exit the working space. Personal locks may have a shower room in which the person take a shower to bind and asbestos particles adhering to them. At the airlocks suction devices are connected, which keep the working space under negative pressure.

Such person locks are often quite complex. The construction and dismantling is correspondingly complex. For larger refurbishment measures, ie refurbishment measures of larger properties, which are associated with a correspondingly high personnel and time, the construction and connection of even complex airlocks in a reasonable ratio. For smaller remedial measures, such as those required in individual rooms of apartments, the use of known person locks is disproportionately expensive. It may be the case that known person locks are so large that a connection to the working space is not possible.

Based on the known prior art, the invention has the object, even with smaller remedial measures to allow safe extraction of the working space.

• - einen ersten Rahmen für den Anschluss der Anschlussvorrichtung an einen Durchgang zum Arbeitsraum,
• - einen zweiten Rahmen,
• - eine Verbindungseinrichtung zur Verbindung des ersten Rahmens mit dem zweiten Rahmen, und
• - mindestens eine Öffnung zum Einlass oder Auslass von Luft in den oder aus dem Arbeitsraum.

To solve the problem, a connection device with the features of claim 1 is proposed. The proposed connection device for connection to a working space comprises according to the invention

• a first frame for connecting the connection device to a passage to the working space,
• - a second frame,
• a connection device for connecting the first frame to the second frame, and
• - at least one opening to the inlet or outlet of air in or out of the working space.

In order to connect the connection device in the region of a passage to the working space, the connection device has a first frame. The first frame may be attached to or in the passage so that persons working in the work space can access the work space via the passage and the connection device. In doing so, they first enter a transition region which is bounded by the connection device which extends between the first frame and the second frame. About the connecting device, the connection device can be optimally adapted to the spatial conditions.

According to the invention, the connection device has at least one opening for the inlet or outlet of air into or out of the working space. The connection device according to the invention thus creates on the one hand the possibility of an exit of persons from or their entry into the working space. On the other hand, it provides the possibility of extraction of the working space. Such extraction will be carried out, for example, in work rooms in which harmful substances are released or degraded during renovation work.

As part of the development has been found that according to the invention also an introduction of air in a working space can be advantageous, namely, when the working space is contaminated and should be kept clean by the introduction of purified air. Such an application is conceivable, for example, in connection with contaminated hospital rooms, in which in a simple manner first the contaminated air escapes through the injection of purified air from the working space and the working space then by a continuous blowing of purified air is kept clean.

The first frame is for connection to the workspace. The second frame advantageously serves to stabilize the connection device and / or to create an entry into the connection device. The connecting device expediently keeps the first and the second frame in the installed state at a distance and advantageously creates a passage - albeit only a short one - through which a person can pass.

Preferably, the connecting device is designed such that the first frame is movable in the direction of the second frame. As a result, the connection device is collapsible, which is particularly advantageous insofar as this makes the connection device portable. It can therefore simply be brought to the relevant work space, possibly carried, and built there. Advantageously, the first frame and the second frame can be brought to rest against each other, with the connecting device possibly remaining between them. Such a construction is very compact and simple.

In a further development of the invention it is proposed that the second frame has a door which is pivotally connected to the second frame. As a result, one can advantageously close the working space. On the other hand, such a construction is very compact and has a simple structure. Advantageously, the second frame acts as a door frame. The door is advantageously hinged to the second frame. The second frame may be formed circumferentially. Then he has two vertical beams and two cross beams. The door seals appropriately against these spars.

At the beginning, the at least one opening has already been mentioned, through which air can be admitted into the working space or discharged from the working space. Preferably, the air is injected or sucked out. In this context, it is considered advantageous that the at least one opening is formed in the connecting device. In this way, the transitional area extending between the first frame and the second frame can be used for discharging the extracted from the working space air and / or for the intake of fresh air. In that regard, the structure of the personal lock can be kept very compact. In addition, the opening in the connecting means provides the ability to laterally dissipate or introduce the air. This saves space, which is particularly advantageous in cramped local conditions.

The transition area created by the connection device therefore preferably has a depth which makes it possible to form the at least one opening in the connection device. The depth of the connecting device corresponds to the distance between the first and the second frame. Preferably, the connecting device has a depth which corresponds to at least the width of the opening in the installed state of the connecting device.

The connecting device advantageously has two side walls, which face each other. The at least one opening is preferably formed in one of the side walls.

A preferred embodiment of the invention is characterized in that at least one further opening is provided on the same side of the connecting device. If the first opening is used for exhaust air, the additional opening for supply air can be used. Both openings are advantageously from the side of the connection device.

A further preferred embodiment is characterized in that at least one first opening is provided on one side of the connecting device and at least one further opening is provided on the opposite side of the connecting device. Such a construction makes the connecting device according to the invention universally applicable, since - depending on the local condition - air can be introduced or withdrawn through one side of the connecting device or the other side. It is particularly advantageous if two openings are formed on each side of the connecting device. For example, air is sucked through one opening and air is introduced through the other opening. Alternatively, it can be provided to introduce (clean) air through one opening and to let out air (possibly contaminated) through the other opening. The two openings on the other side are advantageously closed, as will be explained in more detail below. They can be used in other spatial conditions in which a connection of suction or blowing devices is only possible on the other side of the connecting device, which favors a universal applicability of the connection device.

The frame preferably has two vertical uprights, which stand up in the installed state and are advantageously connected or connectable via at least one transverse spar. The vertical beams are preferably fixedly connected to the at least one transverse spar. This facilitates on-site construction and creates a rigid construction and is especially true when the frame has four spars (two vertical beams and two transverse beams). Preferably, the frame is fixedly connected to the connecting device.

In order to ensure a certain dimensional stability of the frame, it is proposed that the frame is at least partially made of metal. In particular, the frame may be made of steel or aluminum. The latter has a light specific weight, so that the connection device is easy to transport.

For the connection device to be operated reliably, the first frame must be connected to the (existing) passage. In a simple case, the first frame is glued to or onto the passageway by means of an adhesive tape. Such a composite is unproblematic if the size of the frame corresponds to the size of the passage.

However, it is desirable that the connection device according to the invention can be connected to different sizes of passages. In that regard, it is considered to be advantageous if a connecting device that is flexible in design emerges from the first frame. The connection device may be a tarpaulin or a foil which preferably extends substantially in the plane of the frame. The connection device advantageously extends laterally from the frame in the plane of the frame. Thus, if a passage is wider and / or higher than the first frame, the difference in size can be bridged by the connection device. The flexibility of the connection device simplifies the connection to the passage. For example, the tarpaulin is simply glued or nailed to the passage bounding wall or frame. As a result, a substantially airtight connection is created.

According to a preferred embodiment of the invention, the connecting device of the connecting device consists at least partially of a flexible material. Preferably, the flexible material is a foil or tarpaulin. For transport, the connection device can be folded or folded together, so that transport and / or storage are simplified. Against this background, it is considered advantageous if, for transporting the connecting device, the first frame is movable in the direction of the second frame. The connecting device folds together due to its flexibility, whereby the size of the connecting device is reduced.

The film or tarpaulin is preferably made of plastic, since this is generally impermeable to air. Contaminated material can therefore not penetrate the film or tarpaulin. Furthermore, plastic is insensitive to moisture and robust, which is advantageous for rather rough operating conditions on a construction site. The plastic can be fiber reinforced.

The connecting device is preferably flexible. In particular, the material of the connecting device can be flexible. However, in order to give the connecting device a certain hold, it is preferably firmly connected to the first frame and preferably the second frame.

Preferably, the at least one opening of the connecting device defines an opening plane and the first frame forms a frame plane which is inclined with respect to the opening plane. Preferably, air extracted from the working space is removed laterally from the transition region extending between the first frame and the second frame. The angle enclosed by the opening plane and the frame plane is preferably between 60-120 °, more preferably between 80-100 °, for example, about 90 °. It should be noted that the connecting device is preferably flexible, so that the above information is approximate.

A lateral arrangement of the at least one opening with respect to the plane of the first frame has the advantage that the removal of the extracted from the working space contaminated air or the inlet of fresh air is guaranteed even if the connection device is constructed in a narrow corridor.

In an essential embodiment of the invention, it is proposed that in each case at least one connection frame is formed in the connection device, which forms the at least one opening. The connection frame makes it possible to connect a pipe or a hose. This is particularly advantageous if the connection device is designed to be flexible and insofar as a direct fastening would be difficult due to the flexibility. If two lead frames are provided, the second lead frame may be for use with a filter and / or means for unidirectional intake of fresh air. An advantageous embodiment is characterized in that the connecting device has two side walls, in each of which at least one connection frame is formed. This allows flexible extraction (or corresponding introduction of air) from one side or the other side of the connection device.

The connection frame expediently has a certain rigidity for its connection function. It may advantageously consist of metal, in particular of steel or aluminum.

So that the connection device for the transport of the connection device can be made smaller, the connection frame preferably has at least one joint, as a result of which the connection frame can be folded. This makes it possible that the connecting device is also foldable or hinged. The first frame can thus be brought onto the second frame, as a result of which the connection device for transport can be considerably reduced.

The joint can be formed, for example, by the connecting device, which bridges a free space of the connecting frame. In other words, the lead frame is split. There, where the lead frame the space - so a gap - leaves, is the connecting device, which is preferably designed to be flexible. This clearance creates a certain tolerance between the parts of the leadframe, so that a folding of the leadframe is easily possible when folding the connection device.

Furthermore, the connection device advantageously comprises a filter device and / or a device for the unidirectional intake of air. By means of the filter device, in particular the entry of particles and / or suspended particles from the ambient air into the connection device and thus into the working space can be prevented, so that it is ensured via the filter device that the supplied fresh air is not contaminated.

The alternatively or additionally provided device for unidirectional intake of air can be used to supply the working space with fresh air, at the same time ensuring that - regardless of the pressure conditions prevailing on this side and beyond the device - only air is admitted, but not discharged. This can be realized, for example, by means of pivotable flaps ("flaps").

Due to its function, the filter device and / or the device for the unidirectional intake of air is / are preferably inserted or usable in the opening (here: inlet opening) of the connecting device. For connection to the connecting device, a connection frame can be used, as has already been described above and which preferably forms the inlet opening.

In order to ensure the most airtight completion of the working space, the connection device described above on the one hand must allow the outlet of extracted air and on the other hand, the inlet of fresh air. The same applies if fresh air is blown through a first opening in the working space and the air is released through a second opening from the working space. For this purpose, the connecting device of the connecting device preferably has at least one inlet and one outlet opening.

Preferably, exactly one inlet opening and exactly one outlet opening are provided on each side of the connecting device, which are arranged one above the other in the installed state of the connecting device, so that the inlet opening near the bottom and the outlet opening come to lie near the ceiling. The near-bottom arrangement of the inlet opening has the advantage that (possibly harmful) particles that have deposited behind the inlet opening on the ground, entrained by the incoming air and be carried back into the working space to be sucked there with the air. The close-to-ceiling arrangement of the outlet opening has the advantage that hoses or pipes connected thereto do not represent a trip hazard.

The two-sided arrangement on the connecting device in each case an inlet opening and an outlet opening has the advantage that the connecting device is particularly well adapted to the local conditions. When building the connection device can be decided at short notice, whether - depending on the space ratio of the stock - to one side or to the other side sucked (or alternatively blown). The other openings are then closed. Preferably, all openings are equipped with a lead frame. A blind cover is then inserted into the terminal frames, which are not used.

A preferred embodiment of the invention is characterized in that the at least one opening, preferably each opening, is closable or closed by a functional cover, wherein preferably the respective functional cover comprises a filter device, a device for unidirectional intake of air, a blind cover or a pipe connection is. The pipe connection can be a connection for a suction pipe or a supply air pipe. Such an embodiment allows maximum connection freedom. In particular, the supply air and the exhaust air can take place on one side of the connecting device. Then the other two openings are closed by the blind cover. If the spatial conditions allow a connection on the other side of the connecting device, the supply air and the run on the other side, and the vacant openings are closed by the blind cover.

It is proposed as advantageous that the functional cover expediently has an angled leg which engages over the connection frame inwards. As a result, the cover can be supported on the connection frame. If the connection frames have a joint, the connection frame is naturally more unstable than if one has no joint. In that regard, it is considered advantageous if the leg engages over the joint. As a result, the leg stiffens the connection frame and thus the entire connection device.

A development of the invention is characterized in that a suction device is connected to the connecting device, by means of which air can be sucked out of the working space. For this purpose, the suction device is connected or connectable to the connection device, preferably via a hose or a tube. The connection of the suction device to the connecting device via a hose or a tube allows any placement of the suction device with respect to the connecting device, so that the placement can be optimally adapted to the local conditions.

Preferably, the tube provides a flow channel that passes through the connection means. The air from the working space is thus advantageously sucked through the connecting device and introduced.

The connecting device according to the invention serves for connection to a working space. Through the openings of the working space can be sucked or supplied with fresh air. If the connection device is used to extract harmful substances from a work space, which are released, for example, during remedial work, it may be necessary to carry out additional measures for cleaning the persons working in the work space. This applies in particular if the harmful substances are asbestos. In this connection, it is proposed that a shower device, which is detachably connected to the second frame, be connected to the second frame. The shower facility allows the persons to shower off after leaving the workroom. Together with the shower device, the connection device forms a personal lock.

The lock function is implemented in the proposed personal lock on the shower device, which has an input and preferably an output. The latter can be created by the second frame. Preferably, the input and the output are arranged over the corner. In this way, a personal lock can be realized in the smallest space.

Suction devices are also well known in the art as vacuum holdings. In a further development of known suction devices, the suction device has a water tank, which is in line connection with the shower room of the shower device. About the water tank and the line connection, the shower room is supplied with water.

According to a preferred embodiment, the water tank is received in a first housing of the suction device and can be filled via a feed line, which is passed through a second housing, which is arranged on the first housing, so that the supply line opens at an upper side of the second housing. The water tank can thus be arranged close to the ground, so that the center of gravity of the suction device is arranged close to the ground. This reduces the risk of the suction device tipping over. Since the supply line is guided to the top of the second housing, the filling of the water tank can still be made from the top, which simplifies handling and increases comfort.

In the second housing, a control of the suction device is preferably included, so that control elements connected to the control are also arranged in an upper region of the suction device and thus easily accessible.

For sucking the air out of the working space advantageously a hose or a tube is used. Preferably, the tube or tube is in fluid communication with the suction device and has a free end for exhausting air from the working space. For this purpose, the free end is simply placed in the working space so that air can be sucked out of the working space. Preferably, the tube or the tube is designed to be flexible at least in sections, so that the position of the tube or of the tube with respect to the working space can be changed by moving the free end. In order to put the free end as far as possible into the working space, it is proposed that the minimum length of the hose or the pipe is between 2 and 8 m.

The connection device according to the invention is used as follows. First, the connection device is brought to the working space. Preferably, it is initially collapsed and will be opened on the spot. Then it is connected to a passage of the working space. For this purpose, it preferably has the connection device, which is glued, for example, with a wall or frame forming the passage. Finally, air located in the working space can be sucked out of the working space through an outlet opening formed in the connecting device, preferably in the connecting device.

For suction, a hose or pipe having a first end for connection to the connection device and a free end for placement in the working space is preferably used, preferably the free end being placed away from the passage, for example in the area of a wall bounding the working space the passage in the working space opposite. The free end of the hose or pipe is thus placed as far away from the passage as possible, on the one hand to suck air from remote corners of the working space and on the other hand to suck away contaminated air from the passage. Incidentally, it is thus ensured that no fresh air is sucked off, which is preferably introduced in the region of the passage into the working space, preferably through the connecting device.

Preferably, fresh air is introduced into the working space through at least one opening formed in the connecting device. The intake of fresh air ensures that the extracted - contaminated - air from the working space is replaced by fresh air. As a result, the degree of contamination of the air in the working space can be kept low overall.

Preferably, the fresh air is introduced via an inlet opening which is likewise formed in the connection device of the connection device and in which a filter device and / or a device for unidirectional inlet of air is advantageously used. This ensures that only filtered air is admitted or under unfavorable pressure conditions no contaminated air can escape from the working space via the inlet opening.

1 shows a connection device 100 on a wall 101 a workroom behind the wall 101 is, connected.

The connecting device according to the invention 100 has a first frame 102 and a second frame 103 on. Both frames 102 . 103 are through a connection device 104 connected to each other, which is preferably flexible. This may be, for example, a tarpaulin, a foil or a bellows, which may be made of plastic, for example.

The second frame 103 has two vertical bars 105 and two crossbars 106 on that together the second frame 103 form. The second frame 103 is preferably made of metal, for example aluminum. Also the first frame 102 has two vertical bars 105 and two crossbars 106 on that together the first frame 102 form. The first frame 102 is preferably made of metal, for example aluminum.

The second frame 103 preferably has a door 107 on, by which a person through the connecting device 100 can pass through. The door 107 is about joints 108 swiveling with the second frame 103 connected.

For connection of the connection device 100 to the working space, the connection device has a connection device 109 on, which may be, for example, a tarpaulin, a foil or a bellows. The connection device 109 is preferably flexible. This is the connection device 100 connectable to different sizes of passages of the working space, as related to 3 will be explained in more detail. For fastening the connection device 109 on the wall 101 becomes the connection device 109 for example by means of an adhesive tape 110 glued to the wall. This creates an air and dustproof connection.

With the reference number 111 is a suction device characterized, can be sucked through the air from the working space. The suction device is through a hose 112 with the connection device 100 connected. For this purpose, the connection device 100 at least one opening on, as related to 5 will be explained in more detail.

Preferably, the openings in the connecting device 104 educated. The illustrated embodiment has four openings, with two openings on the in 1 right side are arranged and two openings on the left as it is made 2 is apparent. The openings are each preferably covered with a functional cover. In the upper part of the connection device 100 it is a hose connection 113 , The lower section is a filter device 114 , About the hose connection 113 can the hose 112 laterally to the connection device 104 be connected. By means of the suction device 111 Air is sucked out of the working space. Through the filter device 114 fresh (uncontaminated) air passes through the connector 104 through into the workroom.

The connection device 104 is flexible in the illustrated embodiment, whereas the frame 102 and 103 are stiff compared to this. Due to the flexibility of the connection device 104 can the two frames 102 and 103 for the transport of the connecting device 100 be stacked. To fix the two frames 102 . 103 is a fixing device in the form of a belt connection 115 provided by the first frame 102 and the second frame 103 can be connected to each other. Previously - so that the connecting device 104 is sufficiently flexible - the hose connection 113 and the filter device 114 be removed. By means of hand loops 116 the connection device is portable.

It will open 2 Reference is made to the embodiment 1 in a perspective view from the left shows. From this view it becomes clear that in the connecting device 104 a total of four openings are formed, wherein two openings are arranged on each side of the connecting device. In 2 The two left openings are each occupied by a functional cover, in the present case in each case by a blind cover 117 , These blind covers 117 close the openings of the connecting device 104 air and dust-tight, since in the illustrated embodiment, not the left, but the right openings ( 1 ) are used. For other spatial conditions, for example, on the right side of the connection device 100 not enough space to connect a hose 112 is, the blind covers can 117 removed and through other functional covers such as the hose connection 113 be replaced. For this purpose, the functional covers are preferably detachable with the connecting device 100 , in particular with the connecting device 104 , connected and preferably have at least one locking device 118 on. By actuating the locking device 118 (here: turning), the respective functional cover can be removed, as it is in connection with the 4 and 5 will be explained in more detail. To remove shows the blind cover 117 a recessed grip 119 on.

3 shows the embodiment of the back, so from the workspace 120 seen from. In the workroom 120 a passage is formed by a frame 121 is limited. As you can see from this view, the first frame is 102 smaller than the one through the frame 121 limited passage. For air and dustproof connection of the connection device 100 to the workroom 120 has the connection device already in 1 described connection device 109 on that the gap between the second frame 102 and the frame 121 bridged. The connection device 109 is seen (from the workroom) outside on the wall 101 attached, as it is for example 1 evident.

Like it too 1 shows, is the hose 112 to the connection device 104 connected. The hose connection 113 forms a flow channel through the connecting device 104 passes. Inside goes from the connecting device 104 another hose 122 that's a free end 123 having. This free end can be free in the workspace 120 to be placed. Preferably, the free end 123 placed as far away from the passage as possible. In the case of extraction, it is thus ensured that harmful particles are sucked away from the passage - where the fresh air supply is located - so that it can be ensured that the harmful particles do not accumulate in the passage area and on leaving the working space 120 unintentionally be discharged from the work space. The first hose 112 and the second hose 122 can also be formed in one piece.

It will open 4 Reference is made in which the filter device 114 is shown on an enlarged scale. The filter device 114 is with the connection device 104 connected. For this purpose, the connecting device 104 preferably at least one connection frame 124 on. The connection frame 124 is stiffer than the connecting device 104 and provides the necessary rigidity for receiving the filter device 114 , For attaching and removing the filter device 114 this already has related to 2 addressed locking device 118 on. These are knobs. The connection frame 118 is preferably made of metal and is useful by means of rivets 125 at the connection device 104 attached. The connection frame 118 each bounds the opening as they look 5 even clearer.

The connection frame 124 has at least one joint 126 on, whereby the connection frame is foldable. Through the joint 126 can the two frames 102 and 103 be placed on top of each other. In the present case forms the lead frame 124 a free space 127 , This clearance is through the connecting device 104 bridged. The joint 126 So is through the connecting device 104 educated. Such a construction creates a certain tolerance, whereby the frame 102 . 103 are particularly well assembled. Also conceivable is a construction in which instead of the open space 127 a joint is provided, wherein the right frame part 128 and the left frame part 129 pivotally engaged with each other.

5 shows the filter device 114 from the side of the workroom. Here it becomes clear that the connection frame 124 two joints 126 having. These allow a collapse of the lead frame 124 , The locking device 118 ( 4 ) engages on its inside the connection frame each with a driver 130 , On the lower side has the functional cover (here: the filter device 114 ) an angled leg 131 on top of the connection frame 124 inwards - ie toward the working area - and engages over the joint 126 bridged. This will be the joint 126 stabilized what in the assembled state of the connection device 100 has considerable advantages. Preferably, on the first frame 102 a clamping leg 132 hinged towards the second frame 103 is pivotable, or vice versa. This also contributes to the stabilization of the connection device, since in this way the connection device 104 is streamlined. The connection frame 124 forms an opening 133 through which air from the environment is sucked into the working space. As can be seen from the synopsis of the previous figures, the embodiment has four openings. According to the invention, at least one opening is provided.
