description

The invention relates to a connection device for

Connection to a workroom. Under working space is understood in the context of the invention, in particular a contaminated area. The invention is directed, for example, to workspaces in which

asbestos-containing material is degraded. The invention can also be used where the air in a

Work room to be cleaned.

The degradation of asbestos-containing material requires from a health point of view particularly high

safety measures. 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.

Asbestos contaminated areas must be included

Renovation work is constantly kept under negative pressure, To avoid the asbestos from breaking down

contaminated area emerges.

In practice, contaminated with asbestos

Workspaces connected to personal locks, through which persons who carry out work in the work space, in and out of the work space

stepping out. 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. Accordingly complex is their construction and

Degradation. For larger renovation, so

Redevelopment measures of larger properties, which are associated with a correspondingly high staff and time, is the construction and connection of even complex

Personal locks 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

Personal locks are so large that a connection to the work space is not possible.

Based on the known prior art, the invention is based on the object, even with smaller

Rehabilitation measures to allow safe extraction of the work space. 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 framework for the connection of the

Connecting 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.

To connect the connection device in the region of a passage to the working space, the

Connection device on 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 inventive

Connection device thus creates on the one hand the possibility of an exit of persons from or their entry into the work space. On the other hand, it provides the possibility of extraction of the working space. Such a suction will be for example at Make workrooms in which harmful substances are released or degraded during renovation work.

As part of the development, it was found that

According to the invention also an introduction of air in en

Working space may be advantageous, namely, when the working space is contaminated and should be kept clean by the introduction of purified air. Such an application is associated with, for example

Contaminated hospital rooms conceivable in which in a simple way initially the contaminated air escapes through the injection of purified air from the working space and the working space is then kept clean by a continuous injection of purified air.

The first frame is for connection to the workspace. The second frame is advantageous for stabilizing the

Connecting 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 - though only short - gear by which a person

can pass through.

Preferably, the connection device is such

formed such that the first frame is movable in the direction of the second frame. This is the

Connecting device collapsible, which is particularly advantageous in so far as this way the

Connecting device is portable. It can therefore simply be brought to the relevant workspace, possibly

worn, and built there. advantageously, For example, the first frame and the second frame may be brought into contact with each other, with the connecting device possibly remaining between them. Such

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 can be circumferential

be educated. 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. It also offers the opening in the

Connection means the ability to dissipate or introduce the air laterally. This saves space, which

especially advantageous in tight local conditions. The created by the connecting device

Transition region therefore preferably has a depth that allows the at least one opening in the

Form connecting 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 in one of

Sidewalls formed.

A preferred embodiment of the invention is characterized in that on the same side of the

Connecting device is provided at least one further opening. Unless the first opening for exhaust air

can be used, the additional opening for supply air

be used. Both openings are advantageously from the side of the connection device. A further preferred embodiment is characterized

characterized in that on the one hand the

Connecting means at least a first opening and on the opposite side of the connecting means at least one further opening is provided. Such a construction makes the invention

Connection device universally applicable because - depending on the local nature - air introduced through one side of the connecting device or the other side or can be deducted. It is particularly advantageous if two on each side of the connecting device

Openings are formed. 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. You can in other spatial conditions in which a connection of suction or blowing devices only on the other side of the connecting device is possible to use, which favors a universal Einset zbarkeit 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 provides a rigid construction and is particularly true when the frame has four spars (two vertical spars and two cross spars). 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 then

unproblematic if the size of the frame corresponds to the size of the passage.

However, it is desirable that the inventive

Connection device can be connected to different sizes of passes. In that regard, it will be beneficial

viewed when from the first frame one

Connection device goes off, which is flexible. 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

folded or merged, so that

Transport and / or storage are simplified. Before this Background, it is considered advantageous if for transporting the connecting device, the first frame in

Direction to the second frame is movable. The

Connecting device folds due to her

Flexibility together, reducing 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 the foil or tarpaulin

penetrate. Further, plastic

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

educated. In particular, the material of the

Connecting device be flexible. To the

Connection device nevertheless to give a certain grip, it is preferably firmly connected to the first frame, and preferably the second frame.

Preferably, the at least one opening defines the

Connecting means 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 the opening plane and the

Frame level 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

proposed that in each case at least one connection frame is formed in the connecting device, which forms the at least one opening. The connection frame

allows the connection of a pipe or a hose This is particularly advantageous if the

Connecting device is designed to be flexible and insofar as an immediate attachment 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

Terminal frame is formed. This allows one

flexible suction (or an appropriate introduction of air) from one side or the other side of the

Connecting device. Appropriately, the lead frame for his

Connection function a certain rigidity. It can advantageously made of metal, in particular steel or

Aluminum exist. So that the connecting device for the transport of

Connecting device can be made smaller, the connection frame preferably has at least one joint, whereby the connection frame is foldable. 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, for example, by the

Connecting means are formed, which bridges a space of the lead frame. In other words, the lead frame is split. Where the

Terminal frame the space - so a gap - leaves, is the connecting device, which is preferably 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 comprises

Advantageously, a filter device and / or a device for unidirectional intake of air. By means of the filter device, in particular the entry of particles and / or suspended particles from the surrounding

Room air in the connection device and thus in the

Working space can be prevented, so that over the

Filter device is ensured that the supplied fresh air is not contaminated.

The alternatively or additionally provided device for unidirectional intake of air can supply the supply Working room with fresh air serve, being at the same time

It is ensured that, irrespective 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. to

Connection with the connection device can be

Terminal frame can be used, as has already been described above, and preferably the

Inlet opening forms.

In order to ensure the most airtight completion of the workspace, the above-described

Connection device on the one hand 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 in the installed state of the

Connecting device are arranged one above the other, so that the inlet opening near the bottom and the outlet come to lie near the ceiling. The ground level arrangement of Inlet opening has the advantage that (if necessary

harmful) particles that are behind the

Inlet opening are deposited on the ground, entrained by the incoming air and carried back into the work 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 - aspirated to one side or the other side (or alternatively

blown). The other openings are then closed. Preferably, all

Openings equipped with a connection 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 closed or closed with a functional cover, wherein preferably the respective functional cover is a filter device, a device for unidirectional intake of air, a blind cover or a pipe connection. In which

Pipe connection may be a connection for a

Suction pipe or a Zuluftrohr act. Such

Embodiment allows maximum connection freedom.

In particular, the supply air and the exhaust air on the one Side of the connecting device done. Then the other two openings are through the blind cover

locked. If the spatial conditions allow a connection on the other side of the connecting device, the supply air and the drain on the other side, and the free openings are made by the

Blind cover closed.

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

Connecting 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. The suction device is for this purpose, preferably via a hose or a pipe to the

Connecting device connected or connectable. 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 on the

local conditions can be optimally adapted.

Preferably, the hose or the pipe provides a

Flow channel available through the Connecting device passes. The air from the

Workspace is thus beneficial by the

Aspirated and introduced through connecting device.

The connecting device according to the invention serves for

Connection to a workroom. Through the openings of the working space can be sucked or supplied with fresh air. If the connection device is used to from a workspace harmful substances

may be necessary to take additional measures to clean the people working in the workspace, for example, be liberated during remedial work. this applies

especially when it comes to the

harmful substances is 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 people to leave after leaving the room

Shower off working space. Together with the shower device, the connection device forms a personal lock.

The lock function is at the proposed

Realized personal lock on the shower device having 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 facility. 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 close to the ground

be arranged so that the focus 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 extracting the air from the working space comes

advantageously a hose or a pipe for use. Preferably, the hose or tube is in

Fluid communication with the suction device and has a free end for sucking 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 hose or pipe 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 first

collapsed and is 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, in the

Working space located air through a in the

Connecting device, preferably in the

Connecting device, trained outlet opening to be sucked out of the working space.

For sucking off, preferably a hose or a pipe with a first end for connection to the

Used connecting device and a free end for placement in the working space, wherein preferably the free end is placed away from the passage, for example in the region of a working space bounding wall, which is opposite to the passage in the working space. The free end of the hose or pipe is therefore placed as far away from the passage as possible to air on the one hand

to vacuum away the corners of the working area and

on the other hand, to suck contaminated air away from the passage. Moreover, it is thus ensured that no fresh air is sucked off, which is preferably in the region of Passage into the working space, preferably through the

Through connection device is inserted.

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. This allows the

Contamination level of the air in the working space to 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 advantageously a filter device and / or a device for

unidirekt ional intake of air is used. This ensures that only filtered air is admitted or in unfavorable pressure conditions no

contaminated air through the inlet opening of the

Working space can get outside.

In the following the invention is based on a

Embodiment explained in more detail in connection with the accompanying drawings. The drawing shows in:

Fig. 1 in schematic ish representation of a first

perspective view of the connecting device according to the invention from the other side; 3 is a schematic representation of a view of the connecting device according to the invention of the

Working space seen from; Fig. 4 is a first detail view of the invention

Connection device; and

Fig. 5 is a second detail view of the invention

Connection device.

Figure 1 shows a connection device 100, which is connected to a wall 101 of a working space, which lies behind the wall 101.

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

Plastic can exist.

The second frame 103 has two vertical struts 105 and two transverse struts 106, which together form the second frame 103. The second frame 103 is preferably made

Metal, for example of aluminum. The first frame 102 also has two vertical struts 105 and two transverse struts 106, which together form the first frame 102. The first frame 102 is preferably made of metal, for example aluminum. The second frame 103 preferably has a door 107, through which a person can pass through the connection device 100. The door 107 is pivotally connected to the second frame 103 via hinges 108.

For connecting the connection device 100 to the

Working space, the connection device a

Connection device 109, which may be, for example, a tarpaulin, a foil or a bellows. The connection device 109 is preferably flexible

educated. As a result, the connecting device 100 to different sizes of passages of the working space

connectable, as will be explained in more detail in connection with Figure 3. For fixing the connection device 109 to the wall 101, the connection device 109

glued for example by means of an adhesive tape 110 to the wall. As a result, an air and dust density

Connection created. Reference numeral 111 is a suction device

characterized, can be sucked through the air from the working space. The suction device is connected by a hose 112 to the connection device 100. For this purpose, the connection device 100 has at least one opening, as will be explained in more detail in connection with FIG.

Preferably, the openings in the

Connection device 104 is formed. The illustrated embodiment has four openings, wherein two openings are arranged on the right side in Figure 1 and two openings on the left side, as can be seen from Figure 2. The openings are each preferably covered with a functional cover. In the upper area of the Connection device 100 is a

Hose connection 113. The lower region is a filter device 114. Via the hose connection 113, the hose 112 can be connected laterally to the connection device 104. By means of the suction device 111, air is sucked out of the working space. By the

Filter device 114 passes fresh (not contaminated) air through the connecting device 104 into the working space.

The connecting device 104 is designed to be flexible in the illustrated embodiment, whereas the frames 102 and 103 are formed stiff compared to this. Due to the flexibility of the connecting device 104, the two frames 102 and 103 can be stacked for the transport of the connecting device 100. To fix the two frames 102, 103 is a

Fixing device in the form of a belt connection 115

provided by which the first frame 102 and the second frame 103 can be interconnected. Previously, in order for the connecting device 104 to be sufficiently movable, the hose connection 113 and the filter device 114 must be removed. By means of hand straps 116, the connection device is portable.

Reference is made to FIG

Embodiment of Figure 1 shows a perspective view from the left. From this view it is clear that in the connecting device 104 a total of four

Openings are formed, on each side of the

Connecting device two openings are arranged. In Figure 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 blanking covers 117 close the openings of the connecting device 104 air and dustproof, as in the illustrated

Embodiment not the left, but the right openings (Figure 1) are used. For others

For example, where there is insufficient space for the connection of a hose 112 to the right side of the connection device 100, the blind covers 117 may be removed and replaced by other functional covers such as the hose connection 113. For this purpose, the functional covers are preferably detachably connected to the connection device 100, in particular to the connection device 104, and preferably have at least one locking device 118. By pressing the locking device 118 (here: turning), the respective functional cover can be removed, as will be explained in more detail in connection with Figures 4 and 5. For removal, the blind cover 117 has a recessed grip 119.

FIG. 3 shows the exemplary embodiment from the rear, that is to say seen from the working space 120. In the working space 120, a passage is formed, which is bounded by a frame 121. As can be clearly seen from this view, the first frame 102 is smaller than the limited by the frame 121 passage. For airtight and dustproof connection of the

Connection device 100 to the working space 120, the connection device, the connection device 109 already described in Figure 1, which bridges the gap between the second frame 102 and the frame 121. The

Connection device 109 is (seen from the work space) outside attached to the wall 101, as is apparent, for example, from Figure 1. As can also be seen from FIG. 1, the hose 112 is connected to the connection device 104. The hose connection 113 forms a flow channel which passes through the connection device 104. On the inside goes from the connecting device 104 another

Hose 122 from having a free end 123. This free end can be placed freely in the working space 120. Preferably, the free end 123 is placed as far away from the passage as possible. In the case of an extraction is thus ensured that harmful particles from the passage - where the fresh air supply is - are sucked away, so that it can be ensured that the harmful particles do not accumulate in the passage area and upon exiting the working space 120th

unintentionally be discharged from the work space. The first tube 112 and the second tube 122 may also

be formed in one piece. Referring to Figure 4, in which the

Filter device 114 on an enlarged scale

is shown. The filter device 114 is connected to the

Connection device 104 connected. For this purpose, the

Connecting device 104 preferably at least one connection frame 124. The terminal frame 124 is stiffer than the connecting device 104 and provides the required rigidity for receiving the

Filter device 114. For attaching and removing the

Filter device 114 has these already in

Related to Figure 2 addressed

Locking device 118 on. These are knobs. The terminal frame 118 is preferably made of metal and is useful by means of rivets 125 at the Connection device 104 attached. The leadframe 118 each defines the opening, as shown more clearly in FIG. The leadframe 124 has at least one hinge 126, whereby the leadframe is foldable. By the joint 126, the two frames 102 and 103 can be placed on each other. In the present case, the connection frame 124 forms a free space 127. This space is through the

Connection device 104 bridged. The joint 126 is thus formed by the connecting device 104. Such a construction creates a certain tolerance, whereby the frame 102, 103 are particularly easy to assemble. Also conceivable is a construction in which, instead of the free space 127, a joint is provided, in which the right frame part 128 and the left frame part 129 are pivotally engaged with each other.

FIG. 5 shows the filter device 114 from the side of the working space. Here it becomes clear that the

Terminal frame 124 has two joints 126. These

allow folding of the terminal frame 124. The locking device 118 (Figure 4) engages behind each of the terminal frame with a on its inside

Reiber 130. On the lower side has the functional cover (here: the filter device 114) one

angled leg 131 which engages over the connection frame 124 inwards - ie toward the working space - and bridges the joint 126. As a result, the joint 126

stabilized what in the built state of

Connecting device 100 has considerable advantages.

Preferably, a clamping leg 132 is hinged to the first frame 102, which in the direction of the second frame 103rd is pivotable, or vice versa. This also contributes to

Stabilization of the connection device, since thereby the connection device 104 is tightened. The

Terminal frame 124 forms an opening 133, is sucked in the present case air from the environment 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.
