Description

Technical Field

[0001] The present disclosure relates to an accessory structure, and more particularly to a structure that can be used to prevent unauthorized opening of an openable element. Background Art

[0002] An important safety issue faced by residents and companies is the risk of their apartments, houses and offices being burglarized. Locks, latch systems and hinges continue to develop to reduce this problem and hinder the effort of prying open doors. The common way to pry open a door locked to a frame with a latch is to force the door away from the doorpost to which the latch is connected, and toward the doorpost to which the door is connected via a hinge. In this way, the door can be fully moved so that a tool can be inserted between the door and the frame and then apply force to the door in the direction of opening the door. This can be done by a tool (such as a pry bar). The latch is subsequently exposed to stress, and due to this stress, the latch may eventually break. A way to solve this problem is to produce a latch with a more complex locking connector between a higher strength and / or a door and a door frame. Another way is to have a plurality of locking latches on the door. However, this may increase the cost and complexity of the door installation.

[0003] Further, any accessories arranged with the door may require increased strength to prevent obstruction during unauthorized opening of the door.

[0004] Therefore, there is a need for an improved secure structure for a fitting of a door or other openable member. Summary of the invention

[0005] The object of the inventive concept is to provide an improved solution that alleviates the above mentioned drawbacks of the existing solutions. Furthermore, the object is to provide a fitting structure for a frame of an openable element.

[0006] The invention is defined by the accompanying independent claim, embodiments are set forth in the accompanying dependent claims, the following description and the drawings.

[0007] According to the present invention, there is provided an accessory structure for a frame of an openable element, the accessory structure comprising: a first accessory part configured to be arranged on the frame, and a fixing device. The fixing device comprises: a sleeve having an external thread and an internal thread, the sleeve being configured to be attached to an opening in the frame by the external thread; a wall screw configured to extend through the sleeve into a wall beside the frame, thereby attaching the sleeve to the wall, wherein the wall screw is rotatable relative to the sleeve; and an accessory screw configured to fix the first accessory part to the sleeve by engaging with the internal thread of the sleeve.

[0008] The openable element may be a door, and the frame may be a door frame, which may include two door posts and a lintel. The openable element may be mounted to the frame via a hinge. The first accessory part may be mounted to one of the door posts. Alternatively, the openable element may be a hatch, a window, etc.

[0009] In one embodiment, the fixing means may include two or more sets of sleeves, wall screws, and accessory screws. These sets may be used to attach the first accessory parts together. Alternatively, one or more sets may be used to fix another part to the frame.

[0010] The first fitting part may form or form part of a locking plate, an end plate, a latching structure, a hinge or other type of fitting for the openable element. The first fitting part may be connected to the wall via a sleeve and a wall screw, and any force exerted on the first fitting part may be transferred to the wall.

[0011] The sleeve may have a hollow interior in which an internal thread may be provided. One end of the sleeve may be configured to receive an accessory screw to engage with the internal thread. The sleeve may have a bottom end configured to have an opening through which a wall screw may extend, and the bottom end may be configured to provide fixation between the sleeve and the wall screw when the wall screw is attached to the wall. In particular, the bottom end may be provided with an opening that allows a threaded portion of the wall screw to extend through, while a head portion of the wall screw may not be able to extend through the opening. When the wall screw is screwed into the wall, the sleeve attached to the frame by the external thread may be fixed to the wall. The frame may be fixed to the wall by the same connection.

[0012] In one embodiment, the accessory structure may further include a second accessory part configured to be arranged on the openable element, the second accessory part being configured to engage with the first accessory part. The first accessory part and the second accessory part may together form a locking structure, a latching structure, a safety structure or the like, or be part of it. In such an embodiment, the first accessory part and the second accessory part may be movable relative to each other in a first state to enable opening of a door or other openable element, and engage with each other in a second state to prevent opening. In one embodiment, the first accessory part may be a locking plate on the frame, and the second accessory part may be a locking bolt configured to lock the openable element to the frame by engaging with the locking plate in the second state (locked state).

[0013] In one embodiment, the first accessory part may be configured to receive the second accessory part when the openable element is moved to the closed state, and the second accessory part may be removed from the first accessory part by moving the openable element in the opening direction to the open state. Further, the first accessory part may be formed to receive the second accessory part in a first position or a second position, wherein the second accessory part may be removed from or separated from the first accessory part when the second accessory part is in the first position, and the second accessory part may be prevented from being removed from or separated from the first accessory part when the second accessory part is in the second position. When a force is applied to the openable element and / or the second accessory part, the second accessory part may be moved to the second position in a direction substantially perpendicular to the opening direction.

[0014] The advantages of the accessory structure described below may apply when the first accessory part is arranged on the frame and the second accessory part is arranged on the openable element relative to the frame. However, the invention and the advantages described may also apply when the first accessory part is arranged on the openable element and the second accessory part is arranged on the frame.

[0015] If an effort is made to pry the openable element, which may cause the openable element to move slightly in a direction substantially perpendicular to the opening direction, the accessory structure may prevent the openable element from being opened. It may further provide cost-effective and convenient anti-theft protection. The invention may reduce the need for additional or more complex latch structures for the openable element. Furthermore, the accessory structure may be cheaper to manufacture and assemble than a lock with a locking cylinder.

[0016] The effort to pry open the openable element may comprise applying a force thereto substantially perpendicularly to the opening direction in order to move the openable element such that a space between the openable element and the column of the frame appears or expands. This may be done by a tool such as a pry bar. The configuration of the accessory part and the fixing device may provide that the greater the force applied in a direction perpendicular to the opening direction, the greater the engagement between the first accessory part and the second accessory part, and thereby the engagement of the openable element with the frame. Thus, the greater the force that may be applied, the more difficult the openable element may become to open. By means of one or more such structures arranged on the openable element and the frame, forced entry of the openable element may become more difficult.

[0017] In particular, a fixing device extending into the wall beside the frame to which the first accessory part is attached may provide a very strong attachment. An extremely high force would then be required to break the engagement between the first accessory part and the second accessory part. Without the fixing device being attached to the wall, the frame may break and enable illegal access to the openable element. In order to separate the first accessory part from the frame, it may not be sufficient to overcome the resistance between the first accessory part and the frame. Alternatively, it may be necessary to also overcome the resistance between the first accessory part and the wall. Thus, an increased force may be required in the second position to pry open the openable element by separating the first accessory part from the frame. Therefore, the accessory structure may not break very easily when the force applied to the accessory structure is not only transmitted to the frame, but further to the wall.

[0018] The spacing between the frame and the openable element can enable a tool to be oriented so that a force can be applied in the opening direction so as to break a latch arranged on the openable element so that the openable element can be opened freely. One or more tools can be used to apply the force. If the space between the openable element and the column of the frame increases or appears, the accessory structure can prevent the openable element from opening. It may be necessary to insert a space for a pry bar between the openable element and the frame so that sufficient force can be applied in the opening direction so as to break the latch. Thus, the accessory structure can prevent the latch of the openable element from being destroyed.

[0019] A configuration of an accessory structure with a first accessory part and a second accessory part, wherein the second accessory part is removable from the first accessory part when in the first position, can provide that the second accessory part is received by the first accessory part in the first position without applying any force in a direction perpendicular to the opening direction, whereby the structure can not affect the normal use of the openable element. The second accessory part, when arranged on the openable element, can move into and out of engagement with the first accessory part with the movement of the openable element without any significant contact with the first accessory part. Only when the second accessory part moves in a direction perpendicular to the opening direction when the openable element is in use, the second accessory part is received by the first accessory part in a second position in which the second accessory part engages with the first accessory part, such that the second accessory part is prevented from being removed from the first accessory part in the opening direction. The direction substantially perpendicular to the opening direction can extend parallel to and / or in the extension plane of the openable element.

[0020] In one embodiment, when the accessory structure is arranged on the openable element, the opening direction is perpendicular to the extension plane of the openable element. The extension plane of the openable element may be a vertical plane and the opening direction may be a horizontal direction. In the case where the openable element is a door, the door may be rotatable around one of the door posts.

[0021] The second accessory part on the openable element can be moved relative to the first accessory part when closing and opening the openable element. The first accessory part can be separated from the second accessory part when the openable element is in the open state. The second accessory part can be engaged with the first accessory part when the door is in its closed state.

[0022] In one embodiment, the movement of the second accessory part from the first position to the second position may be reversible. If a force is applied, such as by someone trying to pry the door open, so that the second accessory part is moved from the first position to the second position, the second accessory part may still be movable back to the first position. Thereby, the door may be openable, such as by locking a latch structure of the door, even after someone has moved the door to the second position in order to pry the door open.

[0023] In one embodiment, the door handle may be pulled in order to open the openable element.

[0024] In one embodiment, the first accessory part may include a groove, and the second accessory part may be configured to move along the groove when the openable element moves between the closed state and the open state. Through the groove, the first accessory part can engage with the second accessory part by moving the openable element between the closed state and the open state. The groove can be shaped and oriented so that the first accessory part does not block the openable element or the second accessory part when the openable element is regularly closed, and receives the second accessory part without affecting the regular closing and opening of the door. When in the first position and / or the second position, the second accessory part can extend through the groove.

[0025] In one embodiment, the second accessory part may be configured to move from a first position to a second position in a direction substantially perpendicular to the extension of the groove when received by the first accessory part. Movement between the first position and the second position in a direction substantially perpendicular to the extension of the groove may prevent the openable element from accidentally moving from the first position to the second position, because when opening and closing the openable element, forces may generally be applied mainly in a direction along the groove, which may be in the opening direction and in a direction opposite to the opening direction, respectively. Furthermore, movement in this direction may be most advantageous for moving the openable element so as to be able to insert the pry bar between the openable element and the frame.

[0026] In one embodiment, the second accessory part may include a neck portion having a width less than or equal to a width of the groove. The neck portion may allow the second accessory part to move along and engage the groove when the second accessory part is received in the first position, wherein a portion of the second accessory part is on a side of the groove closest to the openable element and another portion is on a side closest to the frame.

[0027] In one embodiment, the second accessory part may comprise a head portion, the width of which is greater than the width of the neck portion and greater than the width of the recess. In one embodiment, the shape of the head portion may provide an increasing cross-section in a direction away from the neck portion. The head portion may ensure that when the second accessory part is in the first position, the second accessory part can only be separated from the first accessory part by a movement of the second accessory part in the opening direction. When the second accessory part is received in the second position, the head portion may prevent the openable element from opening by contacting the first accessory part. The head portion may further provide that the second accessory part cannot be moved through the recess in a direction perpendicular to the extension direction of the recess out of engagement with the first accessory part.

[0028] In one embodiment, the first accessory part may include at least one first abutment surface shaped to receive at least a portion of a head portion of the second accessory part when the second accessory part is in the first position. The at least one first abutment surface may receive the second accessory part in a stable manner and ensure that the head portion is oriented so that the second accessory part can move along the groove when the second accessory part is in the first position. The first abutment surface may be a surface on which the head portion is arranged when the second accessory part is in the first position. When in the first position, the head portion may be in contact with the first abutment surface. For this purpose, the shape of the at least one first abutment surface may at least partially match the surface of the head portion so that when the second accessory part is in the first position, the angle of the head portion relative to the groove is prevented from changing to such an extent that contact between the head portion and the first accessory part blocks movement of the second accessory part along the groove. In an alternative embodiment, the second accessory part may not substantially contact the first accessory part when in the first position.

[0029] In one embodiment, when the second accessory part is in the second position, the head portion may be too wide to move along the groove in a plane perpendicular to the direction of movement between the first position and the second position. Thereby, when the second accessory part is in the second position, the second accessory part may be prevented from moving from the closed state to the open state. When a force above a threshold is applied to the door in a direction substantially perpendicular to the opening direction, the second accessory part may be moved to the second position relative to the first accessory part. In the second position, the neck portion may be in a position such that it cannot engage with the groove and / or move along the groove. The head portion may then be oriented such that the head portion is blocked from moving along the groove due to the width of the head portion being greater than the width of the groove in the intersecting plane of the second accessory part.

[0030] In one embodiment, the first accessory part may include at least one second abutment surface configured to block the head portion from moving along the groove when the second accessory part is in the second position. The second accessory part may be in contact with the second abutment surface when it is moved to the second position. The at least one second abutment surface may be shaped so that when a force is applied to the openable element in the opening direction, the second abutment surface may prevent the second accessory part from moving along the groove. Thereby, the openable element may be prevented from being pried open by the second abutment surface, because the second accessory part may need to move along the groove in order to move the openable element to the open state. The second abutment surface may be provided as a recess in the first accessory part, into which the head portion of the second accessory part may enter when the second accessory part is moved to the second position. The recess may have a shape corresponding to the shape of the head portion, so that when in the second position, the head portion and the second accessory part are prevented from moving in the opening direction. The second abutment surface may be referred to as a head portion receiving surface or a head receiving portion of the first accessory part. The second abutment surface may be formed as a recess in the first part, which is configured to receive the head portion of the second accessory part. The second abutment surface or head receiving portion may be formed to block the head portion in the opening direction. The blocking may be provided by one or more protrusions that extend to block movement of the head portion along the opening direction when the second accessory part is in the second position.

[0031] In one embodiment, the accessory structure can be configured to increase the force required to break a latch locking the openable element to the frame when the second accessory part is in the second position. The force applied to the openable element in the opening direction can be resisted by the force between the first accessory part and the second accessory part of the accessory structure. The strength of the first accessory part and the second accessory part can affect the force required to be applied to the door in the opening direction to pry the door open.

[0032] In one embodiment, there may be an end plate arranged on the frame, with which the locking means on the openable element may interact to lock the openable element to the frame. In order to provide further rigidity and strength to the locking of the openable element to the frame, the end plate may be attached to the frame and / or the wall by one, two or more fixing means, which may extend through the frame into the wall.

[0033] In one embodiment, the first accessory part may include an orienting portion configured to enhance proper orientation of the first accessory part relative to the second accessory part when the first accessory part is arranged on the frame.

[0034] In one embodiment, the second accessory part may include an orienting portion configured to enhance proper orientation of the first accessory part relative to the second accessory part when the second accessory part is arranged on the openable element. The orienting portion of the second accessory part may be an integral part of the head part provided by the shape of the head part. The orienting portion of the second accessory part may be shaped to interact with the orienting portion of the first accessory part.

[0035] In one embodiment, the first fitting part may comprise guide surfaces which are configured to guide the head portion of the second fitting part into the recess by contact between the head portion and one of the guide surfaces. If there is an offset between the position of the first fitting part and its optimal position relative to the second fitting part, the second fitting part may be moved towards said optimal position by contact between the head portion and one of the guide surfaces in order for the second fitting part to be received by the first fitting part when closing the openable element. This movement may be in a direction substantially perpendicular to the opening direction of the openable element. The guide surfaces may be inclined relative to the longitudinal extension direction of the second fitting part.

[0036] In one embodiment, the openable element may be a door and the frame may be a door frame.Alternatively, the openable element may be a hatch or a window.

[0037] In one embodiment, the opening direction may be perpendicular to the extension plane of the openable element.

[0038] In one embodiment, the first accessory part can be arranged on two fixing devices, wherein the longitudinal center lines of the two fixing devices form a line, and wherein, when in the first position, the longitudinal center line of the second part can be offset from said line by a distance of at least 2 mm, preferably between 2-15 mm. In alternative embodiments, the distance can be between 2-10 mm or between 4-6 mm. The longitudinal center line of the fixing device can extend along the longitudinal extension of the sleeve and / or the wall screw. The longitudinal center line of the second part can extend along the longitudinal extension of the head portion and / or the neck portion.

[0039] In one embodiment, the first accessory part may be a first hinge part, which is configured to be arranged on a column of the frame on a hinge side of the openable element, and the second accessory part may be a second hinge part, which is configured to be arranged on the openable element that can be opened relative to the frame. When the door is in the closed position, the second hinge part can engage with the first hinge part, so that separation of the first hinge part and the second hinge part is achieved only by movement of the door towards the open position. The first hinge part and the second hinge part can be formed as or on corresponding parts of the hinge arranged on the frame and the openable element.

[0040] In one embodiment, an accessory screw may include an adapter configured to threadably engage an internal thread of a sleeve, wherein the adapter includes a hollow interior having threads configured to receive the screw by threaded engagement. The adapter may include external threads configured to engage the internal threads of the sleeve. In one embodiment, the interior of the sleeve may initially be unthreaded, and the adapter may be configured to be thread cutting, thereby forming internal threads in the sleeve when the adapter is screwed into the sleeve.

[0041] According to another aspect of the present invention, a door structure is provided, which comprises a door or other openable element, a frame, and at least one accessory structure according to any one of the above embodiments, which is arranged on the frame and / or the door.

[0042] In the context of the present application, when in the closed state, the openable element may be in a locked or unlocked state relative to the frame.

[0043] According to another aspect of the inventive concept, a method for arranging an accessory structure on a frame of an openable element is provided. The method comprises the following steps: arranging a sleeve of a fixing device in an opening in the frame by means of an external thread on the sleeve; arranging a wall screw through the sleeve and the frame into a wall beside the frame so that the sleeve is attached to the wall; arranging a first accessory part on the frame and attaching the first accessory part to the sleeve by means of an accessory screw engaging with an internal thread in a hollow interior on the sleeve. Before arranging the wall screw through the sleeve and into the wall, the sleeve may be arranged on the frame. After attaching the wall screw to the wall, thereby fixing the sleeve to the wall, the accessory screw may engage with the internal thread of the sleeve to attach the first accessory part to the sleeve. Thereby, the first accessory part may be connected to the wall, and any force applied to the first accessory part may be transmitted to the wall. The accessory structure may be an accessory structure according to any one of the above-described embodiments. In some embodiments, the method may comprise the further step of arranging the accessory structure according to such embodiments on the frame of the openable element.

[0066] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be comprehensive and complete and will fully convey the scope of the present invention to those skilled in the art. In the accompanying drawings, the same reference numerals refer to the same elements.

[0067] exist Figure 1 , Figure 2 and Figure 3 In the figure an openable element 1 (here a door) with a frame 3 is shown. In the following, directional terms will be used, which apply to embodiments in which the opening direction of the openable element 1 is in a horizontal opening direction D1 and the openable element 1 extends in a vertical plane, which is normal for a door, but the invention can also be applied to openable elements 1 that are oriented differently. For example, the invention can be applied to an openable element 1 that is a ceiling or floor shutter, the opening direction of which can be vertical. The openable element 1 can also be used for a locker, a cabinet or a safe.

[0068] exist Figure 1, the openable element 1 is shown from a vertical perspective, such that the openable element 1 can be in a closed state and an open state relative to a frame 3. The frame 3 can include two columns 31, 32 and a lintel 33. The lintel 33 can be connected to the columns 31, 32 at opposite sides of the lintel 33. In the embodiment shown, the columns 31, 32 are perpendicular to the lintel 33 and parallel to each other. The openable element 1 is connected to the column 31 by hinges 6, 7, so that the openable element can rotate around an axis A1 extending through the hinges 6, 7. A handle 8 can also be seen, by which the openable element 1 can be opened.

[0069] exist Figure 2 and Figure 3 In FIG. 1 , the openable element 1 is shown from a horizontal perspective, and the openable element is in a closed state and an open state relative to the frame 3 , respectively, and the opening direction D1 is to the left. Figure 4 A closer view from a vertical perspective of the openable element 1 in the open state relative to the frame 3 is shown in FIG. Here, the opening direction D1 is to the right.

[0070] In some of the illustrated embodiments, the fitting structure according to the invention may be described as comprising a fitting structure 5. The fitting structure 5 is illustrated as being arranged on the frame 3 and the openable element 1. The fitting structure 5 comprises a first fitting part 10 and a second fitting part 11. In the figures, the first fitting part 10 and the second fitting part 11 of the fitting structure 5 are seen to be arranged to the column 32 and the openable element 1, respectively.

[0071] exist Figure 3 The second fitting part 11 can also be seen in the embodiment shown, whereas the first fitting part 10 is to some extent concealed by the column 32 in which it extends partially. Figure 1 , Figure 2 and Figure 3 A screwing device 12 can be seen, which connects the first accessory part 10 of the accessory structure 5 to the wall 2 through the column 32. The screwing device 12 is part of the fixing device (9). The fixing device 9 comprises a frame attachment device which is rotatable relative to the screwing device 12, so that the position of the column 32 can be adjusted in translation when the screwing device 12 is screwed into the wall 2.

[0072] The second fitting part 11 can also be a solid part of the openable element 1 .

[0073] At least one first fitting part 10 can also be arranged on a portion of the frame 3 extending perpendicularly to its axis A1, and the second fitting part 11 is arranged on a corresponding surface of the openable element 1. In the case where the openable element 1 is a door, the first fitting part 10 can thus be arranged on the lintel 33 and the doorposts 31, 32. This structure can especially prevent the upper part of the openable element 1 from being pried open by applying a force.

[0074] Embodiments are also possible in which the openable element 1 on which the second fitting part 11 of the fitting arrangement 5 is arranged cannot rotate about the axis A1, for example for which the openable element 1 is completely removed from the frame 3 by a translational movement. For such embodiments, the fitting arrangement 5 can be applied on at least one pair of mutually opposing parts of the frame 3 with respect to the openable element 1.

[0075] In one embodiment, in addition to at least one second accessory part 11 of the accessory structure 5, a latch is arranged on the openable element 1, and in addition to at least one first accessory part 10 of the accessory structure 5, a latch receiving device is arranged on the frame 3, for example on the column 32.

[0076] Fig. 9 It can be seen that parts of the first fitting part 10 are configured to interact with parts of the second fitting part 11. The first fitting part 10 comprises a first abutment surface 18, a second abutment surface 19, optionally a first orientation portion 16, and further optionally a guide surface 20. The first fitting part 10 is configured to receive the second fitting part 11 in a first position by means of the first abutment surface 18, and to receive the second fitting part in a second position by means of the second abutment surface 19. After the second fitting part 11 has been moved from the first position along the force application direction D2, the second fitting part 11 is received at the second abutment surface 19 in the second position. Figure 6 The accessory structure 5 is shown in a state corresponding to the closed state of the openable element 1, without showing the frame 3 and the openable element 1, and Figure 8 Further, the accessory structure 5 is shown in a closer perspective. Figure 7 is shown as being open.

[0077] The second fitting part 11 of the fitting structure 5 comprises a head portion 13, a neck portion 15, an attachment portion 21 and optionally an orientation portion 17. In the embodiment shown, the second fitting part 11 is rotationally symmetrical, but other embodiments are possible. The second fitting part 11 is configured to move along the opening direction D1 and engage with the first fitting part 10 when the openable element 1 is closed in a direction opposite to the opening direction D1. In the closed state of the openable element 1, as shown in FIG. Figure 6 and Figure 8As can be seen, the head portion 13 is within a recess 14 of the first fitting part 10. The recess 14 is shaped and configured to receive the head portion 13 of the second fitting part 11 and to allow the head portion 13 to be movable within the first fitting part.

[0078] exist Fig.10 , a first fitting part 10 and a second fitting part 11 of the fitting arrangement 5 are seen so as to correspond to the open state of the openable element 1. Here, the attachment portion 9 of the first fitting part 10 has been largely omitted so as to better see how the first fitting part 10 engages with the second fitting part 11. The first fitting part 10 can here be separated from the second fitting part 11. From this state, the second fitting part 11 can be moved along the groove 14 counter to the opening direction D1 of the openable element 1 in order to be received by the first fitting part 10, such as the head portion 13 being moved into the groove 14 and into the interior thereof into a first position corresponding to the closed state of the door, such as Figure 6 and Figure 8 What is shown.

[0079] The second fitting part 11 is movable in the opening direction when the second fitting part 11 is received by the first fitting part 10 in the first position. The second fitting part 11 is shown with a neck portion 15 that is narrower than the edge 22 of the groove 14, so that if the first fitting part 10 is properly oriented relative to the second fitting part 11, the neck portion 15 is not blocked by the edge 22 of the groove 14 when the openable element 1 is moved from the open state to the closed state. An embodiment is possible in which the neck portion has the same width as the groove 14, in which case contact between the neck portion 15 and the edge 22 of the groove 14 may occur at a certain point when the openable element 1 is moved between the closed state and the open state.

[0080] The head portion 13 is shaped such that the second fitting part 11 is not blocked by the edge 22 of the groove 14 when entering the first fitting part 10 if the first fitting part 10 is properly oriented relative to the second fitting part 11. To do this, the second fitting part 11 should be arranged on the openable element 1 at a suitable position relative to the position where the first fitting part 10 is arranged on the frame 3 in terms of what height, horizontal position and how much the head portion 13 protrudes from the openable element 1. If the head portion 13 protrudes too little from the openable element 1, the head portion 13 may be blocked by the surface of the groove 14, and if the head portion protrudes too much, the head portion may be blocked by the frame 3.

[0081] The first fitting part 10 optionally has a first orientation portion 16 configured to facilitate proper orientation when the first fitting part is arranged on the post 32. One surface of the optional first orientation portion 16 is configured to contact the frame 3. In the illustrated embodiment, the first orientation portion 16 is shaped as a disc, and the groove 14 extends through the first orientation portion 16. The second fitting part 11 optionally has a second orientation portion 17 configured to facilitate proper orientation when the second fitting part is arranged on the openable element 1. One side of the second orientation portion 17 is configured to contact the openable element 1.

[0082] In the embodiment shown, the head portion 13 has a conical frustum shape, but other shapes are possible, depending on the shape of the first fitting part 10. Other shapes of the neck portion 15 (shown as a cylinder or a disc) are also possible, depending on the shape of the first fitting part 10.

[0083] In some embodiments, the second fitting part 11 is somewhat flexible relative to the openable element 1 and is arranged with a certain offset from the optimal position of the first fitting part along the side of the openable element 1 on which the second fitting part is arranged relative to the first fitting part. If the offset is small enough, when closing the openable element 1, depending on the flexibility, one of the guide surfaces 20 (in the middle) may be moved away from the guide surface 20. Fig. 9 The second fitting part 11 can be guided into the groove 14 by the contact between the guide surface 20 and the second fitting part 11 .

[0084] Further, the first abutment surface 18 is configured to receive the head portion 13 in the first position so that the head portion 13 is in contact with the first abutment surface 18. When the openable element 1 is moved towards the open state relative to the frame 3, the head portion 13 and the neck portion 15 can move from the first abutment surface 18 along the groove 14. If a force is applied to the openable element 1 in a force application direction D2 substantially perpendicular to the opening direction D1 when the head portion 13 is received in the first position, the head portion 13 can move to be received by the second abutment surface 19 in the second position. Such a force may be caused by an effort to pry open the openable element 1. The force in the force application direction D2 can be applied in the following way: with a tool such as a pry bar in order to be able to apply a force in the opening direction, for example by inserting the pry bar between the opening element 1 and the frame 3 so that a part of the pry bar is located on the opposite side of the openable element 1 with respect to the opening direction. The second abutment surface 19 is shaped to prevent the head portion 13 from moving along the groove 14 in the opening direction D1 when the second accessory part 11 of the openable element 1 is received in the second position. The head portion 13 is then oriented such that its cross section is so large that the head portion cannot move from the second position along the groove 14, because the head portion is blocked by the second abutment surface 19. Forces exerted on the openable element 1 in the opening direction D1 are then resisted by forces between the first fitting part 10 and the second fitting part 11 of the fitting arrangement 5. If at least one latch is arranged on the openable element 1 in combination with at least one latch receiving portion arranged on the frame 3, the fitting arrangement 5 can thereby prevent the latch from being broken.

[0085] exist Fig. 9 , lines P1 and P2 are shown as the topmost side of the groove 14 for the head portion 13 at the first position and the second position (eg, Fig. 9 The approximate position of the boundary surface (as seen in FIG. 1 ) is provided to visualize the function of the first position and the second position. The movement of the head portion 13 from the first position to the second position (as seen in FIG. 1 ) is provided to visualize the function of the first position and the second position. Fig. 9 The force applied in the direction D2 downwards may cause the head portion to be unable to move along the groove 14 due to the width of the head portion 13 relative to the width of the boundary surface of the groove 14 at P2.

[0086] exist Figure 53 shows a column 32 of a frame 3 together with two fitting structures 5, wherein a first fitting part 10 is arranged on the column 32. The openable element 1 on which the second fitting part 11 is arranged is not shown here, so that the column 32 and the fitting structure 5 can be better seen. A plurality of fitting structures 5 can be used in order to increase the force provided by the fitting structure 5 and thus prevent the openable element 1 from being pried open. When the openable element 1 is in the second position, the force applied in the opening direction D1 is resisted by the force between the first fitting part and the second fitting part 11 of the plurality of fitting structures 5. Therefore, a plurality of fitting structures 5 can be arranged on the column 32.

[0087] In some embodiments, the second fitting part 11 can be returned to the first position by relaxing the force that moved the second fitting part 11 to the second position and possibly applying a force in a direction opposite to the direction D2 of the force applied when moving the second fitting part 11 to the second position. In this way, the head portion 13 can be moved to be received by the first abutment surface 18. Thereafter, the openable element 1 can be regularly opened by applying a force in the opening direction D1 so that the head portion 13 moves along the groove 14.

[0088] Fig.11 An embodiment of an accessory structure 5 with a fixing device 9 is shown. The fixing device 9 comprises a sleeve 26, a screwing device 12 (which may be a wall screw), and an accessory screw 25. The sleeve 26 has threads on the outer surface, which are configured to engage with the frame when arranged on the frame 3. The sleeve 26 is hollow and provided with an internal thread. The internal thread is configured to engage with the accessory screw 25, which is configured to attach a first accessory part 10 to the fixing device 9. The wall screw 12 is rotatable relative to the sleeve 26. In the embodiment shown, there are two fixing devices 9, to which the first accessory part 10 is attached. In an alternative embodiment, the first accessory part 10 can be attached to a single fixing device 9. The fixing device 9 provides a solid and secure attachment of the first accessory part 10 to the frame 3 and the wall.

[0089] In this embodiment, the first fitting part 10 is formed as a plate with a groove 14 extending from one side. The features of this first fitting part 10 engaging with the second fitting part 11 in the second position are similar to the embodiments presented above. At the end of the groove 14, the first fitting part 10 is provided with a head portion receiving surface, also referred to as the second abutment surface 19 as described above. When entering the groove 14, the second fitting part 11 moves to the first position when the neck portion 15 has moved to the end of the groove 14. When the second fitting part 11 moves along the force application direction D2, the head portion 13 moves to the second position to engage with the groove 14, or as described above, with the second abutment surface 19. In this second position, the second fitting part 11 is prevented from moving in the opening direction D1 relative to the first fitting part 10.

[0090] The head portion receiving surface is shaped to correspond to the shape of the head portion 13 of the second fitting part 11. In order to correspond to the tapered head portion 13, the head portion receiving surface is provided as a corresponding recess. The recess is provided at the end of the groove 14 or around it. The head portion receiving surface or its recess is shaped to prevent the head portion 13 from moving in the opening direction D1 when the second fitting part 11 has been moved to the second position.

[0091] exist Fig.11 In the embodiment shown, the first accessory part 10 is connected to two fixing devices 9, each of which comprises screwing means 12 for attaching to the wall. In another embodiment, the accessory structure 5 shown can also be provided with only one fixing device 9. The fixing device 9 comprises a sleeve 26, to which the first accessory part 10 is attached. In one embodiment, the first accessory part 10 can be configured to be attached to a pre-installed fixing device 9. The first accessory part 10 is attached to the fixing device 9 by means of one or more screws 25, which are configured to be screwed into the hollow interior of the sleeve 26. This attachment of the first accessory part 10 to the wall via the fixing device 9 is applicable to any embodiment of the accessory of the openable element.

[0092] Fig.12An embodiment of a fitting structure 5 is shown, in which both the first fitting part 10 and the second fitting part 11 have different designs. The second fitting part 11 has a head portion 13 and a neck portion 15. The head portion 13 is of flat shape and / or disc shape. The first fitting part 10 is formed as a plate with a groove 14 extending from one side. The features of the first fitting part 10 engaging with the second fitting part 11 in the second position are similar to the embodiments presented above. At the end of the groove 14, the first fitting part 10 is provided with a head portion receiving surface, also referred to as the second abutment surface 19 as described above. When entering the groove 14, the second fitting part 11 moves to the first position when the neck portion 15 has moved to the end of the groove 14. When the second fitting part 11 moves along the force application direction D2, the head portion 13 moves to the second position to engage with the groove 14, or as described above, with the second abutment surface 19. In this second position, the second fitting part 11 is prevented from moving in the opening direction D1 relative to the first fitting part 10.

[0093] The head portion receiving surface is shaped to correspond to the shape of the head portion 13 of the second fitting part 11. In order to correspond to the flat or disc-shaped head portion 13, the head portion receiving surface is provided with a corresponding recess. The recess is provided at the end of the groove 14 or around it. The head portion receiving surface or its recess is shaped to prevent the head portion 13 from moving in the opening direction D1 when the second fitting part 11 has been moved to the second position.

[0094] exist Fig.12 In the embodiment shown, the first fitting part 10 is connected to two fixing devices 9, each of which comprises screwing means ( Fig.12 In another embodiment, the accessory structure 5 shown may also be provided with only one fixing device 9.

[0095] Fig.13An embodiment of a first fitting part 10 and a second fitting part 11 is shown when the second fitting part 11 is in a first position. There are two screwing means 12 for the first fitting part 10, which are configured to attach the first fitting part 10 to a frame and / or a wall. The two screwing means 12 are arranged along a line. The second fitting part 11 is in a first position and in a position in which it can be moved to a second position. The center of the second fitting part 11 can then be arranged offset by a distance X1 from said line between the two screwing means of the first fitting part 10. The distance X1 can be between 2-15 mm, between 2-10 mm, or between 4-6 mm. The center of the second fitting part 11 can be a radial center, a longitudinal center line of the second fitting part 11. The second fitting part 11 can be arranged on the openable element by means of an attachment means 21, such as a screwing means. The attachment means 21 can have a longitudinal center line, which can constitute a center with an offset from the line between the screwing means 12 of the first fitting part. The line between the screw-on devices 12 may be formed by a line between two longitudinal center lines of the two screw-on devices 12. The offset may be provided by an extension of the groove 14, thereby providing a first position of the second fitting part 11 when the openable element is in the closed state. This functionality of the groove 14 being configured to receive the second fitting part 11 in the first position with the described offset is applicable to any embodiment of the invention disclosed herein.

[0096] Fig.14 An embodiment of the accessory structure 5 is shown from two different angles, in which the second abutment surface 19 or head portion receiving surface is formed as part of the edge of the groove 14. One or two protrusions 14a are provided along the edge of the groove. The protrusion 14a extends in a direction perpendicular to the extension of the groove 14. When moving toward the open state or the closed state, the second accessory part 11 moves along the groove 14 so that the neck portion 15 extends so that the head portion 13 can move past the protrusion 14a. This allows the second accessory part 11 to move to the first position. When a force in the direction D2 is applied to move the second accessory part 11 to the second position, the protrusion 14a at the edge of the groove 14 prevents the second accessory part from moving in the opening direction D1. This is provided by the protrusion 14a blocking the route of the head portion 13. The second abutment surface 19 is formed by the protrusion 14a together with at least a portion of the edge of the groove 14. The first accessory part 10 is configured to be screwed by the accessory screw ( Fig.14 Attached to the sleeve 26 of the fixing device 9 (not shown).

[0097] Fig.15 An embodiment of the accessory structure 5 is shown from two different angles, wherein similar to Fig.14In the embodiment of the present invention, the second abutment surface 19 or the head portion receiving surface is formed as part of the edge of the groove 14. One or two protrusions 14a are provided along the edge of the groove 14. Fig.15 In the embodiment shown, the head portion 13 of the second fitting part 11 is provided with one or two recesses 13a which correspond in shape and size to the projections 14a so as to be engageable therebetween. When a force in the direction D2 is applied so as to move the second fitting part 11 into the second position, the projections 14a prevent the second fitting part from moving in the opening direction D1. This is provided by the projections 14a blocking the path of the head portion 13. Fig.15 In the embodiment of the present invention, the blocking is further provided by the engagement of the recess 13a of the head portion 13 with the protrusion 14a. The second abutment surface 19 is formed by the protrusion 14a together with at least a portion of the edge of the recess 14. Fig.15 As shown, the second fitting part 11 may have a rectangular shape. The rectangular shape may be provided on the head portion 13 and the neck portion 15. When having a rectangular shape, the head portion 13 may be wider than the neck portion 15 in one direction of the rectangular shape, or preferably in at least two directions. When the second fitting part 11 moves in the opening direction D1 along the extension of the groove, the head portion 13 may be wider than the neck portion part in two directions facing the edge of the groove 14. When having a rectangular shape, the second fitting part 11 may be fixed to the openable element 1 by two fastening means (such as screws) in use. This may provide a more rigid attachment to the openable element 1.

[0098] The protrusion 14 a may be formed by punching on the edge of the groove 14 .

[0099] In some embodiments, the first accessory part 10 is formed as a plate extending in a first plane. The groove 14 may have an edge extending in a second plane parallel to but offset from the first plane. The second abutment surface 19 may also extend in the second plane. In e.g. Fig.14 and Fig.15 This functionality is provided in embodiments of In those embodiments, the protrusion extends in a direction towards the first plane.

[0100] Figures 16 to 21 An embodiment is shown in which the first and second parts of the fitting structure are configured to be arranged in connection with the hinge of the openable element. The fitting structure is suitable for preventing the openable element 1 from being removed from the column 31 of the frame 3 on which the openable element 1 is arranged via the hinges 6, 7, see Figure 1 .exist Fig.16 In FIG. 3 , the column 31 is shown from above with the hinge-side fitting structure 23 and the hinge 6 . Fig.176, 7, wherein the column 31 is omitted in order to better see the fitting structure 23 and the hinge 6. The first fitting part 40 and the second fitting part 50 of the hinge-side fitting structure 23 are respectively attached to the first part 60 and the second part 61 of at least one of the hinges 6, 7, which can rotate relative to each other around the axis A1.

[0101] The hinge side fitting structure 23 can be used in combination with the above-mentioned fitting structure 5, or as a separate fitting structure. The attachment of the fitting structure 5 to the wall using the fixing device 9 as described above also applies to the components of the hinge side fitting structure 23.

[0102] The first fitting part 40 is arranged on the column 31 by means of a fixing device 9. The fixing device 9 comprises screwing means 12 which are screwed into the wall 4, see Figure 1 The fixing device 9 further comprises a sleeve 26 attached to the column 31 of the frame 3. A rigid and secure attachment of the hinge 6 can be provided, which is thereby fixed to the wall. By screwing the first fitting part 10 directly through the column 31 into the wall 4 via the fixing device 9, any force applied to the openable element 1 for movement but prevented by the hinge-side fitting structure 23 can be transmitted not only to the column 31, but also to the wall 4. By this design, the strength of the overall structure is significantly increased when the openable element 1 is subjected to forces such as those generated by a forced break-in attempt.

[0103] The second fitting part 50 is arranged with the attachment portion 53 on the openable element 1. Fig.18 , a column 31 is shown, on which a first fitting part 40 of a hinge-side fitting structure 23 is arranged. A first portion 60 of a hinge 6, to which the first fitting part 40 is attached, is arranged on the column 31. The first fitting part 40 comprises a recess 42, which is configured to receive a second fitting part 50 when the openable element 1 is closed.

[0104] exist Fig.19 and Fig. 20 In FIG. 1 , the second fitting part 50 of the hinge-side fitting structure 23 is seen to be arranged on the openable element 1 . The second part 61 of the hinge 6 is seen to be arranged on the openable element and attached to the second fitting part 50 . However, the second fitting part 50 may be largely hidden by the openable element 1 .

[0105] The second fitting part 50 comprises a head portion 52 which is configured to be received by the groove 42 of the first fitting part 40. The second fitting part 50 is configured to move in the extension plane of the openable element 1 and to protrude from the openable element 1 in a direction D3 which is substantially perpendicular to the opening direction D1 and the axis A1. When the first fitting part 40 and the second fitting part 50 are arranged as intended onto the openable element 1 and the column 31, respectively, the head portion 52 moves into the groove 42 along the direction D3 by closing the openable element 1 in a direction opposite to the opening direction D1. In the closed state of the openable element 1, the hinge 6 with the hinge-side fitting structure 23 can be seen without the attachment portion 41 of the first fitting part 40, the head portion 52 being in the groove 42.

[0106] The first fitting part 40 is configured to allow the second fitting part 50 to be uncoupled from the first fitting part 40 when the openable element 1 is opened by rotating the openable element 1 about the axis A1 provided by the at least one hinge 6, 7 by a rotational movement in the direction D1. However, even when the openable element 1 is slightly opened, the head portion 52 may be in the groove 42 so as to prevent the openable element from being removed from the post 31, also if the openable element 1 is forced slightly open. The first fitting part 40 may comprise an abutment surface 43 configured to prevent the second fitting part 50 from being uncoupled from the first fitting part 40 if the openable element 1 is or has been moved in translation in a direction not parallel to the direction D3. Such a translational movement may result from an effort to pry the openable element 1 open, for example by inserting a tool between the openable element 1 and the post 31 to apply a force to the openable element 1. For such a translational movement, the abutment surface 43 of the first fitting part 40 blocks the head portion 13 from moving out of the groove 41 in a direction opposite to the direction D3.

[0107] This force is therefore resisted by the forces between the first fitting part 40 and the second fitting part 50. The hinge-side fitting structure 23 can be used on one or several hinges 6,7.

[0108] The first fitting part 40 and the second fitting part 50 of the hinge-side fitting structure 23 can alternatively be mounted to the door column 31 and the openable element 1 without being attached to the hinges 6, 7. Several hinge-side fitting structures can be used for the openable element, some of which are attached to the hinge. Both the hinge-side fitting structure attached to the hinge and the hinge-side fitting structure not attached to the hinge can then resist the effort to remove the openable element 1 from the column 31 by the force between the first fitting part 40 and the second fitting part 50 of the hinge-side fitting structure 23.

[0109] Fig.21An embodiment is shown in which a hinge 6 is used to attach to a frame and a wall by means of a fixing device 9, the hinge comprising a screwing device 12 configured to extend into the wall. The hinge 6 can be screwed onto the sleeve 26 via an adapter 45. The adapter 45 is configured to fit into the threaded hollow interior of the sleeve 26 and has its own threaded hollow interior configured to receive the accessory screw 25 from the hinge 6. The adapter 45 comprises an external thread for screwing with the sleeve 26 and an internal thread for screwing with the accessory screw 25 of the hinge 6. The hinge 6 constitutes a first part of the accessory structure. In one embodiment, the hollow interior of the sleeve 26 may initially be unthreaded, and the adapter may be configured to be thread cutting, so that threads are formed when the frame attachment screw is screwed in.
