Description

The invention relates to an insect protection door, comprising a rectangular leaf frame made of several frame profiles, a horizontally running bar profile extending between two vertical frame profiles, the bar profile having a longitudinal groove undercut on at least one side.

Such an insect protection door is usually placed as an attachment door in front of a permanently installed door on the building side, for example a terrace or balcony door. It usually comprises a rectangular vent frame, which is composed of four mostly mitered frame profiles, usually extruded aluminum profiles, with the frame profiles being pressed together via corresponding connecting elements. Due to the height of the sash frame, a horizontally extending transom profile is usually provided between the two vertically extending frame profiles. Above and below the bar profile, insect protection fabrics are arranged in the remaining frame openings, which are usually fixed via a piping in a circumferential groove that is formed via corresponding, complementary grooves on the individual frame profiles and the bar profile.

The casement itself is e.g. arranged in a mounting frame that is fixed on the building side. The sash frame is pivotably mounted on this mounting frame. The insect protection door can be a door that can only be swung open to one side, and therefore runs against a stop in the closed position. Alternatively, it can be a swing door, which means that the casement can swing through the mounting frame on both sides. Alternatively, the casement can also be attached to a frame of the door and pivoted.

The transom profile, which is located approximately halfway up the sash, has a on at least one side, usually on both sides longitudinal groove undercut on at least one side of the groove, and if such grooves are provided on both sides, they are offset in height from one another, so they can be deepened into the profile, which is usually about 8 mm wide. The respective undercut also serves as a grip section on which the operator can grip in order to move the casement manually if necessary.

In the closed position, such a frame can be easily fixed, for example, by means of magnetic elements that are provided on the sash and on the assembly or frame and interact with one another in the closed position. Nonetheless, if the sash is knocked lightly or if there is a strong draft or the like, the sash may open unintentionally.

The invention is therefore based on the problem of specifying an improved insect protection door.

To solve this problem, the invention provides for an insect screen door of the type mentioned at the outset that a manually longitudinally displaceable slide with a locking element arranged thereon is received in the groove and between a release position in which the locking element is disengaged from a mounting frame or frame in which the casement is pivoted in the assembly position, is provided element receptacle, and is displaceable in a locking position in which the locking element engages in the element receptacle.

According to the invention, the insect protection door is equipped with a locking device which makes it possible to lock the casement firmly in the closed position on the mounting or frame, so that the casement cannot open unintentionally. For this purpose, a longitudinally displaceable slide is provided which, according to the invention, is received in the longitudinal groove, that is to say is positioned sunk in the groove and is guided in it so as to be longitudinally displaceable. Connected to the slide is a locking element that has the slide can also be moved linearly. The locking element on the sash side is assigned a corresponding element receptacle on the assembly or frame side, into which the locking element is inserted when it is moved from the release position into the locking position. This intervention ensures that the sash frame is securely locked in the assembly or frame.

If such a groove is only provided on one side, it is expediently undercut on both sides, so that the slide received in it is fixed against falling out of the groove. If grooves are provided on both rung sides, a correspondingly geometrically designed slide is expediently used, as will be discussed later, which is inserted into both grooves, which are each undercut on one side, the slide then being fixed against falling out via the two respective undercuts .

Due to the fact that the slide is received in the groove and is freely accessible to the rung side, the slide can be moved manually between the two positions very easily for the operator, for which purpose a trough or the like can be formed on the slide, for example that the operator can use his finger to move. Operation is therefore very easy.

Another particular advantage is that, due to the arrangement of the slide in the groove, the slide does not protrude, or only projects insignificantly, over the top of the rung. There is the possibility of receiving the carriage completely sunk in the groove, or in such a way that it is essentially flush with the rung surface or only protrudes minimally by a few millimeters. In any case, an extremely narrow construction is possible in this way without the locking device at all protruding from the rung profile to the side, or if at all then not to a significant extent. This leads to the fact that the sash frame does not or only marginally builds up in its width despite the integration of the locking device is therefore still extremely narrow and, with complete integration or flush closure of the slide, only shows the depth of the rung in this area. This in turn offers the particular advantage of also mounting the casement on doors in which a roller blind that can be moved vertically in front of the closed insect protection door moves with only a very small distance from the insect protection door. This distance is often only a few millimeters, so that it is not possible to integrate a locking device with, for example, buttons which protrude laterally from the rung profile and which can be operated manually. The insect protection door according to the invention with the slide integrated in the groove provides a remedy here.

As described, it is conceivable to provide a groove on only one side of the rung and to integrate the slide there. In this case, the insect protection door can only be operated manually from one side via the grip groove, as can the locking device. If a bilateral operating option is to be provided, a further development of the invention also provides a longitudinal second groove, undercut on at least one side, on the other side of the rung, which is offset in height from the first groove, the carriage with a first carriage section in the first Groove and is received with a second slide portion in the second groove. The slide thus has two slide sections which are likewise arranged offset in terms of height and which each engage in one of the grooves. The two grooves are expediently connected to one another via an elongated rung recess, which is quasi-slot-like, which recess extends into the rung profile from an end face adjoining the vertical frame profile, the slide reaching through the recess with a narrow connecting section connecting the two slide sections, to which, viewed in the sliding direction, a slide recess extending to the opposite end of the slide connects. The grooves are therefore connected to one another via an elongated slot recess, which enables the carriage with the two carriage sections, which also have a corresponding recess, to be inserted and the two carriage sections to be inserted into the respective grooves. The connecting section reaches through the rung recess, so it is received in this slot and runs in the slot when the slide is moved.

This insertion takes place, as with only one groove provided on one rung side, from the end face of the rung profile, where one or both of the grooves are axially open so that the respective slide can be pushed in. In the case of only one groove, the fixation against lateral falling out is expediently carried out by an undercut on both sides of the groove; in the case of two grooves and slide sections engaging them, an undercut on only one side in the respective groove is sufficient to secure the slide with the two slide sections.

Appropriately, a stop limit for the sliding movement is provided both in the release and in the locking position, which ensures that the carriage, regardless of whether it is only provided on one side or on both sides, can only be moved between these two positions.

If a quasi double-sided slide with the two slide sections is provided, the limit stop for the release position can be implemented via the two opposing ends of the rung and slide recesses, the limit stop for the locking position being a side surface of the vertical frame profile against which the slide in the Locked position running, or a stop element inserted into one or both grooves. This stop element, which is fixed in position, can be, for example, a locking element which, as will be discussed below, serves to lock the slide in a corresponding position and with which the slide interacts with corresponding locking sections. Alternatively, a stop element can be provided on the slide body itself, with which it runs directly against the side surface of the vertical frame profile.

If only a one-sided groove and therefore only a simple slide is provided, the limit stop can be implemented, for example, in that the Groove is opened a short distance via a longitudinal slot, a projection on the carriage engaging in this slot, which strikes against the end of the slot in the release position and which runs against the side surface of the adjacent vertical frame profile in the locking position, with the alternative of course also Carriage itself can run against this side surface to limit the stop.

In an expedient further development of the invention, locking means can be provided for locking the carriage in the release and / or the locking position. This locking means makes it possible to easily fix the slide in the respective position so that it does not inadvertently move slightly axially in the direction of the locking position due to centrifugal forces, for example when the sash frame is pivoted open where it is in the release position. Because this would lead to the locking element also being displaced axially and being pushed out of the casement somewhat. When the casement is closed again, the locking element, which has been pushed out slightly, would run against the assembly or frame, and damage could occur. An unintentional release of the locking position, that is to say when the casement is deliberately locked in the frame, is not desirable either. Unintentional opening can then occur and, for example, insects or other animals can get through the insect protection door. All of this is remedied if the locking means according to the invention are provided which lock either the release position or the locking position or, preferably, both.

In a further development of this variant of the invention it can be provided that the locking means comprise a first locking element, which is received in the or in both grooves, and at least one second locking element provided on the slide and laterally overlapping the first locking element. A separate locking element is therefore provided, which is inserted into one or both of the grooves, also from the open rung face, and is fixed there. This first locking element interacts with at least one second locking element provided on the slide side, which laterally overlaps the first locking element, that is, when viewed from the open groove side, engages over the first locking element. When the carriage is displaced, the second locking element is consequently pushed over the first locking element, one or both of the locking positions being defined by the interaction of the two locking elements. On the one hand, this lateral overlap allows for simple locking, on the other hand, it also results in a visually appealing arrangement, since the slide, which preferably fills the entire groove, is only moved relatively and overlapping to the first locking element, which preferably also fills the groove, so that in the end there is always a visually appealing, compact unit.

In the event that two slide sections are provided on the slide, a second locking element which laterally overlaps the first locking element is provided either on one or, expediently, on both slide sections. This means that the carriage is locked in this case at least via one interaction plane between the two locking elements, but preferably via two, namely when a second locking element overlapping the first locking element is provided on each of the two carriage sections.

For simple locking, a locking receptacle is expediently provided on the first locking element and a locking projection is provided on the second locking element, or vice versa. After the second locking element laterally overlaps the first, the locking projection and the locking receptacle are provided on the side surfaces which are adjacent to one another, so that a simple locking connection can be achieved.

If two grooves are provided, the first locking element is preferably designed so that it engages in both grooves, that is to say that it has corresponding element sections which can be positioned in the grooves, these element sections being connected to one another via a connecting section. To axially fix the first locking element so that it does not interfere with the Moving the slide from the locking position to the release position, the first locking element can expediently reach through the rung recess in a recess extension with the connecting section and be supported on the one hand on a shoulder of the recess extension and on the other hand on the side surface of the vertical frame profile. The slot-like recess through which the connecting section of the slide extends is slightly widened in a short, end-face area, so that a shoulder is formed. The first locking element rests against this shoulder with its connecting section, is therefore axially supported here and cannot move axially with the carriage. On the opposite side, the locking element ultimately rests on the side surface of the adjacent vertical frame profile, so that it is securely fixed in the assembly position. Alternatively or additionally, the first locking element can also be glued into the groove or grooves.

In the embodiment described above, a first locking element, that is to say a component separate from the slide, is used in order to achieve the position locking. Alternatively, it is conceivable that the locking means have at least one latching recess assigned to the release position and / or at least one latching recess, for example an embossing or the like, in the or each groove and a latching projection provided on the slide or one or each slide section, which is in the release and / or the locking position engages in the respective latching recess. In this very simple embodiment of the invention, the groove base is consequently provided with one or two latching depressions, for example by embossing or pressing in. A locking projection is formed on the slide, which can easily snap into the respective locking recess in the corresponding position. The slide is fixed laterally in the groove undercut on one or both sides, so it can only move insignificantly relative to the groove base. This enables a corresponding, easy locking fixation in the corresponding positions, but at the same time it is ensured that the carriage, when it is moved from the respective locked position, is still movable despite lateral guidance on the undercut grooves, thus still sufficiently can slide, although it may be slightly tensioned against the groove base. In this case, there is no need to provide a separate locking element.

As described, a locking element is provided on the slide, which is moved with it and can be moved, as it were, out of the casement in the direction of the assembly or frame and back. In order to fix the locking element on the slide, the slide expediently has a corresponding receptacle in which the locking element is fastened, the locking element reaching through a recess in the adjacent vertical frame profile. The locking element is pressed into the receptacle, alternatively it can also be glued in. It extends linearly away from the slide and passes through a corresponding recess in the vertical frame profile and of course, if provided and necessary, in the first locking element. In the release position, it does not protrude, or protrudes slightly, from the frame profile, but only to the extent that it does not rest on the assembly or frame or engage in the element receptacle there. This only takes place when the slide and thus the locking element are displaced linearly.

The locking element is expediently a bolt or a rod which engages through a corresponding hole in the vertical frame profile and, if necessary, a hole or opening in the first locking element.

According to an expedient further development of the invention, it can be provided that the movable slide or each slide section fills the groove in an almost form-fitting manner. This means that the slide or each slide section lies almost completely in the groove, that is to say that this is almost completely filled by the slide and consequently no notable slot or the like remains visible. The visually appealing impression can be further improved in that the slide or each slide section can have a flat visible surface. This means that the groove is then closed flat.

As described, the slide or each slide section can be received in the groove deeper than the surface adjacent to the groove. Particularly preferably, however, the surface of the slide or the slide itself runs flush with the adjoining rung surface, which is particularly appealing when the slide or each slide section has a flat visible surface, since a flush overall surface is then formed from the rung surface and the Slide surface results. In the event that the slide protrudes slightly from the surface when using an extremely narrow bar profile, this protrusion should be a maximum of 4 mm, preferably less.

For a simple movement of the slide to move it between the two positions, a finger recess is preferably provided on the slide or on each slide section, into which the operator can reach with his finger and over which the slide can be moved.

The slide and optionally the first locking element itself are preferably plastic components, preferably simple injection-molded components. On the one hand, this offers a simple and inexpensive production option, but on the other hand it also offers the possibility of producing the slide or the first locking element in any color so that a visual contrast to the color of the casement can be created.

Finally, it is conceivable that a marking is provided in the or each groove, which is covered by the slide in the release position and exposed in the locking position. The corresponding locking position can be made visually visible via this marking, for example a colored point, for example a red point, so that the user can always find out about the respective state of the locking state.

The casement itself can only be swiveled to one side or both sides from the assembly or frame. So it is either a simple insect screen door or a swing door.

Fig. 1 shows an insect protection door 1 according to the invention, comprising in the example shown a mounting frame 2 as well as a sash frame 4 pivotably mounted in this via corresponding hinge connections 3, which in the example shown can be swiveled out to both sides, thus representing a swing door.

The mounting frame 2 consists of four mitered frame profiles 5, 6, 7, 8, which are fixed or pressed to one another in the area of the edges via corresponding connecting elements. In the assembly position, the assembly frame is fixed in position on the building side.

The sash frame 4 also consists of four frame profiles 9, 10, 11, 12, which are mitered and connected to one another, preferably pressed, via corresponding connecting elements in the corner area. In the lower area there is a horizontally running stiffening bar 13 and a sheet metal 14 that fills the lower area. In the middle area there is a bar profile 15, which extends from one vertical frame profile 10 to the other vertical frame profile 12 and is in turn fixed to these via corresponding connecting elements . The open frame areas above and below the rung profile 15 are filled with corresponding insect protection fabrics 16, 17, which are each provided with a piping that is provided in a corresponding circumferential groove on the frame profiles 9, 10, 12 and the connecting strut 13 and the rung profile 15 in are fixed in a known manner.

All frame and rung profiles, etc. are usually metal extruded profiles, usually made of aluminum.

The rung profile 15 has on one side a longitudinal groove 18 which is undercut at one, here the upper end 19. On the opposite side, see Fig. 2 , a groove 20 is also provided, which, however, is arranged offset in height from the first groove 18 and which is also undercut, here at the upper end 21 as well. Both grooves 18, 20 enable the operator to access, the operator can reach under the undercut ends 19, 21 with his fingers and actively move the wing. So it is about grip grooves.

Furthermore, a locking device 22 is provided, which is clearly accessible from both sides of the sash 4. The locking device 22 has a slide 23 which has two slide sections 24, 25 which, as will be discussed below, are connected to one another, but one slide section 24 being inserted into the groove 18, while the other slide section 25 is inserted into the groove 20 is used. Connected to the slide 23 is a locking element 26, here in the form of a bolt or a rod, which is firmly fixed in a corresponding receptacle on the slide 23 and which engages through a corresponding recess 27 or hole in the vertical frame profile 10. In the Fig. 1 and 2 the locking position is shown, as it were, in which the locking element 26 is pushed out of the frame profile 10 and the slide 23 is in the locking position. This is only done for purposes of illustration, since usually, when the casement 4 is pivoted open, the locking arrangement 22 is of course in the release position.

The Fig. 1 and 2 furthermore show a marking 58, 59 in each of the two grooves 18, 20, which indicates that the slide 23 is in the locked position. This marking 58, 59 can be, for example, a colored point that is glued or painted on or the like. In the release position, the respective marking 58, 59 is covered by the slide 23.

The Figures 3 and 4 show a section of the insect protection door 1 according to FIG Fig. 1 and 2 , wherein the mounting frame 2 is not shown in more detail, but only a component 28 that is intended to symbolize the vertical frame profile 6 of the mounting frame 2, or that is arranged on it. In any case, an element receptacle 29 is shown here, into which the locking element 26 can engage in the locking position. Such or a similar component 28 would be attached to a frame when the casement 4 is supported.

Fig. 3 shows the release position in which the locking device 22 is located. The carriage 23 is based on the vertical frame profile 10 and compared with Fig. 4 , pushed into a release position far to the right. The user can accomplish this displacement in a simple manner by engaging with a finger in a finger recess 30 formed on the slide 23. In the release position, the slide 23 is locked on a first locking element 31, for which purpose a second locking element 32, which will be discussed in detail below, is provided. Both locking elements 31, 32 interact via a slight snap-in connection.

If the sash frame 4 is to be fixed in its position after the sash frame 4 has been closed, the slide 23 is pushed to the left by engaging the finger recess 30, which means that the locking element 26 is extended and pushed through the locking receptacle 29. Since this is fixed in position on the mounting frame 2, the casement 4 is consequently firmly fixed in the mounting frame 2. If it is to be released again in order to pivot it open, the slide 23 is again to the right in the in Fig. 3 The shown release position is pushed and the fixation is released. In the locking position, too, the slide 23 is locked by means of the two locking elements 31, 32, again by means of a slight locking mechanism.

These locks in the release and locking positions ensure that the carriage 23 does not inadvertently change its position.

As stated, the slide 23 has the two slide sections 24, 25 which are received in the respective grooves 18 and 20 on the two opposite sides of the rung profile 15. Seen from the outside, he looks into the Figures 3 and 4 The slide section 25, not shown, because it is located on the other rung side is identical to the slide section 24, that is, a finger recess 38 is also provided there, as well as for interaction with the first locking element 31, which also extends into the second groove 20, a corresponding second locking element 32 is provided. The only difference is that the corresponding height offset of the slide sections 24, 25 is given.

Fig. 5 shows a view accordingly Fig. 3 , the vertical frame profile 10 not being shown here. The slide 23 is shown with the slide section 24, which in turn is corresponding Fig. 3 is in the release position. It can also be clearly seen here that the first locking element 31 is received both in the first groove 18 and in the second groove 20. It thus has corresponding sections 33, 34 which are connected to one another via a connecting web 35. The first locking element 31 is a separate component and is used separately from the slide 23. It is inserted by pulling the slide 23 from the in Fig. 5 shown open end face 36 of the rung profile 15 is inserted, after which the first locking element 31 is inserted. This has a recess 37 through which the locking element 26 engages. The first locking element 31 is, as already Figures 3 and 4 show, fixed in position, so is not moved with the carriage 23. Like the slide 23, the first locking element 31 is also preferably a simple plastic injection-molded part.

Fig. 6 now shows the locking device 22 or the carriage 23 from the other side, i.e. with a view of the second carriage section 25. The finger recess 38 also provided on this side and a second locking element 39, which is also provided on this side and which is connected to the first locking element 31, are shown cooperates. This means that there is a corresponding, slight locking fixation of the carriage 23 in the release and in the locking position on both sides.

Fig. 7 shows a top view of the end face 36 of the sash profile 15. The two grooves 18, 20 and the two undercut ends 19 and 21, which allow fingers to be reached under in the open groove area, are clearly visible.

Also shown is the first locking element 31 with the two sections 33, 34 and the recess 37 through which the locking element 26 engages. It can be seen that the two sections 33, 34 are connected to one another in one piece via the connecting web 35.

The two sections 33, 34 are overlapped laterally by the second locking elements 32, 39, which are provided on the slide 23 and on the slide sections 24, 25, respectively. This overlap enables the formation of a simple, easy locking fixation by forming corresponding locking grooves and locking projections on the first locking element 31 and the second locking elements 32, 39, which snap into each other in the respective end positions and thus enable the fixation. It also ensures the assault, see the Figures 3 and 4 that, on both sides of the casement 4, there is an appealing exterior with a quasi-closed surface, since the slide 23 merges almost immediately onto the first locking element 31.

How out Fig. 7 As can also be seen, the surface 41 of the first slide section 24 and the surface 42 of the second slide section 25, see also the preceding figures, are flush with the respective surface 43, 44 of the rung profile 15. This means that the slide 23 or the slide sections 24, 25 run flush with the rung profile surface, they do not protrude laterally, so that the entire locking device 22 is completely sunk or received in the rung profile 15. This enables a particularly narrow design of the casement 4 so that the insect protection door 1 according to the invention can also be installed where a roller blind running in front of the insect protection door 1 only runs at a minimal distance from the insect protection door 1.

Fig. 8 shows a partial view of the rung profile 15. The two grooves 18, 20 with the two undercut ends 19, 21 are shown.

Furthermore, a slot-like rung recess 45 is shown, which extends axially from the end face 36 and forms a stop 46 at its rear end, on which, as will be discussed below, the slide 23 strikes to limit the stop. Furthermore, a recess enlargement 47 is provided in the front area, which is delimited by a shoulder 48. This shoulder 48 serves as an insertion limit for the first locking part 31, which runs with its connecting section 35 against this shoulder 48 and is thereby fixed in position in this direction. In the other direction, the fixation takes place via the vertical frame profile 10.

The Figures 9 and 10 show on the one hand the slide 23 ( Fig. 9 ) and on the other hand the first locking element 31 ( Fig. 10 ). A side view of the slide 23 is shown, the slide section 24 being shown here, the surface 41 of which lies in the plane of the drawing. The second slide section 25 is connected via a connecting section 49.

The finger recess 30, which is formed in the direction of one end of the carriage, is shown on the first carriage section 24. At the opposite end there is a second locking element 32, on the underside of which a locking projection 50 is formed. This flat, second locking element 32 overlaps the first locking element 31, as already described.

A second locking element 39 is also formed on the second slide section 25, on which a latching projection 50 is also formed, which is visible here. This latching projection 50 also interacts with corresponding latching receptacles on the latching element 31 over which it engages, which will be discussed below.

The slide 23 has a slide recess 51 which is positioned in such a way that it is pushed into the recess 45 of the rung profile 15, as it were. In the release position, the end 52 of the connecting section 49 runs against the stop 46 of the recess 45. With the connecting section 49, the slide 23 is guided in the recess 45.

A slot-like recess 53 is also provided between the locking elements 32 and 39, which makes it possible for the two locking elements 32, 39 to be separated from one another to the extent that they can accommodate the first locking element 31 between them.

This is in Fig. 10 shown. It can be seen to have latching receptacles 54 visible in this illustration on one side, while these latching receptacles 54 are not visible on the opposite side and are therefore only shown in dashed lines. The front latching receptacles 54 interact with the latching projection 50 of the latching element 32 on the slide section 24, the rear latching receptacles 54 interact with the latching projection 50 provided on the slide section 25. The position of the respective latching receptacles 54, seen axially, is such that the latching receptacles 54 shown on the right in the figure define the release position and the latching receptacles 54 shown on the left define the locking position. In each position, a latching projection 50 snaps into one of the latching receptacles 54.

The locking position is again defined or limited in a sliding manner via the connecting section 49, after the connecting section 49 runs with the other end 55 against the first locking element 31, which is fixed in position.

This process is detailed in the Figures 11 and 12 shown. In this, on the one hand the slide 23, on the other hand the first locking element 31 is shown. From the slide 23, the slide section 24 with its flat surface 41 and the recessed grip 30 is shown facing forward, the second sliding section 25 is shown quasi from the inside. The first locking element 31 has to the respective Visible sides of the sections 33 and 34 also each have flat surfaces 56, 57 which accordingly correspond to the surfaces 41, 42 of the slide sections 24, 25.

Fig. 11 shows the release position in which the carriage 23 is shifted from the fixed-position locking element 31 to the right. The two locking projections 50 of the second locking elements 32, 39 engage in the corresponding locking receptacle 54, the position is fixed by this.

If the slide 23 is now to be moved into the locking position, the user either grips the finger recess 30 or 38 and pushes the slide 23 starting from Fig. 11 to the left. The locking engagement of the locking projections 50 in the locking receptacles 54 is thereby released, the slide 23 is shifted to the left until it is in the locking position according to FIG Fig. 12 runs in, where the locking projections 50 snap back into the locking receptacles 54 and the carriage 23 has run against the first locking element 31. The locking element 26 is pushed into the corresponding locking receptacle 29. To release the lock, the slide 23 can easily be pushed in the opposite direction.

The embodiment described above shows a slide 23 consisting of two slide sections 24, 25, that is to say that this locking device 22 can be actuated from both sides of the casement 4. If, for example, because the bar profile 15 has a longitudinal groove only on one side, the locking device 22 is only to be arranged on one side, then this longitudinal groove should expediently be undercut on both sides. The basic principle, however, remains the same. In this case, too, the slide 23 is pushed into this longitudinal groove; it is fixed via the two groove shoulders. The axial displacement limitation can in turn take place by means of a suitably attached slot in which a slide projection engages. Likewise, a first locking element can also be used here, which effects locking in the corresponding positions.
