The inner frame 100 further comprises a side section 130, and a top section 142 and a bottom section 144. The side section 130 is arranged opposite the bracket section 120. The top section 142 and the bottom section 144 are arranged between the side section 130 and the bracket section 120 so as to form a frame. The bottom section 144 has a first end portion 144a and a second end portion 144b. The first end portion 144a is connected to the bracket section, and the second end portion 144b is connected to the side section 130. In a similar way, the top section 142 has a first end portion 142a and a second end portion 142b, where the first end portion 142a is connected to the bracket section 120, and the second end portion 142b is connected to the side section The top section 142 and the bottom section 144 is configured to be moVable in order to adapt the size of the frame 100. This will be discussed more in detail with reference to Figs. 3 and 4a-c.

The top section 142 and the bottom section 144 are each arranged with two fastening means 110, 111, 112, 113. The top section 142 is arranged with one fastening means 110 close to the first end portion 142a and one fastening means 111 close to the second end portion 142b. The bottom section 144 is arranged with one fastening means 112 close to the first end portion 144a and one fastening means 113 close to the second end portion 144b.

The inner frame 100 comprises at least two fastening means 110, 111, 112, 113, where at least one is arranged on the top section 142 and at least one is arranged on the bottom section The fastening means 110-113 extends in a direction separated from the direction of the longitudinal extension of the top and bottom sections 142, 144 (as shown for example in Figs. 3 and 4a-c). Preferably, the fastening means 110- 113 extends in a direction substantially perpendicular to the longitudinal (horizontal) direction of the top and bottom sections 142, 144 as well as the longitudinal (vertical) extension of the bracket section 120 and the side section 130, respectively. The fastening means 110-113 may be seen as protruding parts, for example as protruding legs.

The inner frame 100 is adjustable sideways, i.e. by moving the fastening means 110-113 in a horizontal manner along the length of the top section 142 and the bottom section 144. Moreover, the inner frame 100 is telescopically adjustably up and down in a vertical direction by sliding the top section 142 and the bottom along the bracket section 120 and the side section 130. The inner frame also has at least two fastening means 110-113 or “table legs” for connection to a rack 10, which may for instance be a conventional 19 inch rack. The fastening means 110-113 is removably connected to the inner frame 100, thus allowing horizontal adaptation to the rack 10 during assembly. As illustrated by the horizontal arrows in Fig. 2, the fastening means 110-113 is movable in relation to the inner frame 100 and thereby adaptable to the size of the rack 10 onto which it is connectable. The fastening means 110-113 allows for an easy installation process where no tools are needed. Moreover, the fastening means 110-113 is arranged such that only front access of the rack 10 is needed during installation of the arrangement 200 onto the rack Fig. 3 shows an embodiment of an arrangement 200 being attached to a rack 10. The frame 100 has a bracket section 120 relative to which the remaining portions of the frame may be extended and/or adapted in a vertical direction. The frame 100 may be of fixed-length. In other words, the top section 142 and the bottom section 144 is configured to be movable in order to adapt the size of the frame 100. The bracket section 120 typically has a fixed length which corresponds to the height of the door assembly 190. The height of the door assembly 190 substantially corresponds to the distance between the top section 142 and the bottom section 144 of the frame The top section 142 and bottom section 144 are movable in a direction corresponding to the length of the bracket section 120. This direction is substantially vertical as seen in for instance Fig. 2. Similarly, the top section 142 and bottom section 144 are movable in a direction corresponding to the length of the side section 130. When the inner frame 100 of the arrangement 200 is attached to the rack 10, the direction of movement would be perceived as substantially vertical. For instance, the top section 142 and bottom section 144 are fixed to the bracket section 120 and the side section 130 through fixation means 161. The fixation means may be in the shape of a knob, screw, bolt or the like. Typically, the top section 142 may be movable between an upper end position - at a level corresponding to the top of the door assembly 190 - and a center position of the door assembly 190. Similary, the bottom section 144 may be movable between a lower end position - at a level corresponding to the bottom of the door assembly 190 - and a center position of the door assembly 190. Both the top section 142 and the bottom section 144 extend substantially horizontally between the vertically arranged 120 and 130 when mounted onto the rack The top section 142 and the bottom section 144 are movably attachable to the bracket section 120 and the side section 130 in the way described above at both of their respective end portions 142a-b and 144a-b. For instance, the end portions of the top section 142a-b and the bottom section 144a-b comprise an elongated slit 160 in which the fixation means 161 can run and be fixed. The top section 142 and the bottom section 144 may then be fixedly attached to the bracket section 120 and the side section 130 at a desired position, by screwing the fixation means 161. The slit 160 in the first and second end portions 142a-b and 144a-b of the top section 142 and bottom section 144 may also be replaced by holes arranged with a distance from one another.

Preferably, corresponding slits 121 and 131 are present on the bracket section 120 and side section 130, respectively. This way the fixation meanscan be run through both the slits of the top section 142 and the bottom section together with both the slits 121, 131 of the bracket section 120 and the side section 130, respectively.

Now turning to the Figures 4a-c illustrating an embodiment of an arrangement 200. As previously described, the arrangement 200 comprises a door assembly 190. The door assembly 190 comprises a fastening section 195, a first section 196, a second section 197 and a third section 198. The fastening section 195 is arranged opposite the first section 196, and the second section 197 and the third section 198 are arranged opposite each other. The second section 197 is arranged adjacent to the fastening section 195 on one side, and adjacent to the second section 196 on the other side. All four sections together form a frame enclosing a cover section 191. The cover section 191 is preferably a plate or similar flat structure having a plurality of grid holes, as shown in for example Figs.4a-c. However the cover section 191 may also be a flat structure that does not comprise any grid holes. The cover section 191 may be constructed in metal, plastic or any other suitable material. In the embodiment shown in Fig. 3, the cover section 191 is made of a transparent material, such as Poly(methyl methacrylate).

The fastening section 195 comprises connecting means 194 for connecting the door assembly 190 to the bracket section 120. In the specific embodiment shown in Figs. 4a-c, the fastening section 195 comprises two connecting means 194, arranged in a spaced apart relationship. The connecting means 194 may for example be one or a plurality of hinges, or similar mechanical structure allowing the door assembly 190 to be arranged on the bracket section 120 in a movable manner. If one single hinge is used, it may be in the form of a piano hinge.

In the embodiment shown in Figs. 4a-c, the fastening section 195 comprises two barrel hinges 12 arranged near the end potions of the fastening section 195. It is preferred if the fastening section 195 is pivotally arranged with the door assembly 190 once it is assembled together.

In the embodiment shown in Figs. 4a-c, the bracket sectioncomprises two barrel hinges 122 arranged near the end potions of the bracket section 120. However, other types of hinges are also applicable Within the scope of the invention. The door assembly 190 may for instance be attachable to the vertical bracket section 120 using one or more hinges.

The door assembly 190 further comprises a locking device 180. The locking device 180 is preferably arranged on the cover section 191 of the door assembly 190, near the first section In one embodiment, the locking device 180 comprises a key hole and an associated key. The locking device 180 may be any conventional keyed lock assembly. It may for example comprise a lock cylinder (not shown).

In an alternative embodiment, the locking device 180 comprises a remote locking system, such as a smart lock, Where the locking device 18 can be controlled using an extemal device, such as a mobile phone. Benefits of such a locking system is that the status of the door assembly 190 can be checked remotely, the user can receive notifications When the door assembly 190 is opened, as Well as giving and revoking remote access to visitors, service provides and so on. This embodiment Will soon be described in detail With reference to Figs. 8a-b.

In yet one embodiment the locking device 180 comprises both a mechanical key hole and key as Well as a remote locking system.

In an optional embodiment, the door assembly 190 is further arranged With closing means (not shown). The closing means may for example be magnets, arranged to further increase to locking, or pads arranged to soften the closure of the door assembly.

The fastening means 110 each has a first end 110a and a second end 110b. Once the inner frame 100 is assembled onto the rack 10, the second end of the fastening means 110 is facing the rack 10 and the first end is facing the door assembly 190 (once it is assembled onto the inner frame 100). The same applies to the other fastening means 111, 112 and Each fastening means 110-113 comprises an engagement part 115 and a securing part 114. The engagement part 115 is arranged on the second end ofthe protruding part 110-113. The engagement part 115 may comprise a hook shaped portion 116 (as shown in Figs. 6-7). The engagement part 115 is configured to be inserted in a mounting hole 2 of the rack 10, as illustrated in Fig.

The securing part 114 is arranged on the first end 110a of the fastening means 110-113. The securing part 114 is configured to secure the engagement part 115 in the mounting hole 2 ofthe rack 10. The securing part 114 may comprise an elongated element 118, 118” that at least partly extends along an inner part of the fastening means or protruding part 110-113. The elongated element 118, 118” may for instance be a threaded, rod-like element. One end of the securing part 114 is provided With an adjustment means 117. The adjustment means 117 is configured to fasten the engagement part 115 in the mounting hole 2 ofthe rack 10. The adjustment means 117 may be a Wingnut or the like. The Wingnut provides a good grip for the thumb and finger and alloWs for tightening the fastening means 115 Without using any tools. Optionally, the adjustment means 117 may be another type of nut, such as an acom nut or cap nut. Other types of nuts are possible as Well. The fastening means 110-113 Will be discussed more in detail With reference to Figs. 6- Figs 5a-c shows an embodiment of an arrangement 200, Where details of the fastening means 110-113 are shown in detail in Figs. 5b-c. In this embodiment the fastening means 110 is arranged With a clamping plate 119. The clamping plate 119 comprises an opening 119a arranged to receive the elongated element 118, 118” and the adjustments means 117. If a clamping plate 119 is used, it is thus arranged in conjunction With the securing part 114 of the fastening means 110- In Figs. 6a-b, the fastening means 110-113 comprises a shell cover 150. The shell cover 150 has at least one recess 151 in the area located adjacent to the securing part 114. This recess 151 may also be regarded as a slit Which extends along a transverse Width W of the fastening means. The top section 142 and bottom section 144 are configured to be movable or run in this recess 151, in a direction perpendicular to the length L of the fastening means 110-113. One can also regard this as such that the inner frame 100 is Wedged into the recess 151 or slit and that the inner frame 100 extends transversely through each fastening means 110-In the embodiment shown in Figs. 6a-b, the second end ll0b of the fastening means 110-113 comprises a tapered portion 152. The tapered portion 152 is configured to be inserted inside the mounting hole 2 of the rack Altematively, the tapered portion 152 is first fastened to an adapter plate with quadratic mounting holes. Afterwards, the adapter plate may be fastened to the rack 10 by fasteners, such as for instance a wingnut.

When tightening the fastening means 110-113 with the adjustment means 117, an edge portion 116” of the hook shaped portion 116 (of the engagement part 115) comes into abutment against the front side of the rack 10, i.e. on the side facing the user during installation of the frame 100. Eventually, enough resistance is achieved with the force directed by the adjustments means 117 onto the rack 10 such that the frame 100 is held securely in place. The installer will experience the resistance as he or she screws the adjustment means tighter towards the rack 10. Notably, the hook and wingnut fasteners, i.e. the fastening means 110-113, are moveably connected to the frame allowing horizontal adaptation to the rack.

The shell cover 150 encompassing the interior of the fastening means 110- 113 may be displaceable in the lengthwise direction of the fastening means. Put differently, when the engagement part 115 has been inserted into the mounting holes 2 of the rack 10 and upon tightening of the adjustment means 117, the shell cover 150 will move in the same direction of the adjustment means, namely towards the rack 10. This will cause the edge portion 116” to contact a portion surrounding the respective mounting hole 2 on the front of the rack 10. Meanwhile, an end portion 116” ° of the engagement part 115 is in contact with a rear side of the rack 10. By “front side of the rack” is meant the side facing the installer. The side where the fiberoptic cables are situated or hidden is called the rear side. One can interpret the rack 10 as a metaphorical door frame of a house. In that case, the front side of the rack would correspond to the outside of the house.

The cover 150 may be arranged with a clamping pin 153. The clamping pin 153 may be of a 10 mm dimension, but other dimensions are possible as is known from a person skilled in the art.The tapered portion 152 on the second end 110b of the fastening means 110 can be used to assist in sliding the fastening means into place. One can say that the tapered portion 152 acts as a guide that leads the edge portion 116” of the hook shaped portion 116 into contact with the rack 10. Please note that this principle applies to the rest ofthe fastening means 111, 112 and 113 also disclosed herein.

Fig. 6c illustrates an elongated portion 118 as previously described.

Figs. 7a-b shows one embodiment of the fastening means. In the drawings, the fastening means 110-113 has been depicted as a substantially longitudinal element with a fixed length. Optionally, the fastening means has a Variable length. It may also be telescopically displaceable along a longitudinal portion (or length L) thereof. Preferably, the length L of the fastening means 110- 113 corresponds to at least the transverse width of the bracket section 120 and the side section 130 of the inner frame 100. The length L may be in the range of 70-85 mm, and more preferably in the range of 78 mm. The length ofthe body L1 may be in the range of 40-55 mm, and more preferably around 46 mm.

The transverse width W of the fastening means may be in the range of 10- 18 mm, and more preferably around 14-16 mm. The length of the recess R may be in the range of 3-5 mm, and more preferably around 4 mm.

The elongated element 118, 118” may be movable in relation to the shell cover 150 on an inside of the fastening means 110-113. Optionally, the elongated element is fixedly attached to the shell cover 150 of the fastening means 110-113 at an interior part 154 thereof. The attachment of the elongated element 118, 118” to the interior part 154 may for instance be through welding of the two parts. If the elongated element 118, 118” is movable in relation to the shell cover 150, screwing the adjustment means 117 along the threaded portion of said element 118, 118°, will cause a movement ofthe fastening means 110-113 in a direction towards the front of the rack 10 as a result of an internal engagement of elongated element 118, 118” and the inside part 154 of the shell cover 150. If the elongated element 118, 118” is stationary in relation to the shell cover 150, screwing the adjustment means 117 along the threaded portion of said element118, 118°, will cause a movement ofthe fastening means 110-113 in a direction towards the front of the rack It should be noted that the adjustment means 117 together with the elongated element 118, 118” are adapted to lock or secure both the frame 100 and the hook portion 116 together. Further, the elongated means 118 is adapted to secure the horizontal/sideways movement of the frame Fig. 7c shows the fastening means 110-113 according to another embodiment. Here, the hook portion 116 is formed by bending the engagement part 115 to form the shape of a hook. In this embodiment there is a substantially smooth transition between the end portion 116” of the hook portion 116 and the rest of the engagement part 115. Alternatively, the hook portion 116 may be shaped by cutting out material in the end portion 116” ° of the engagement part 115. The end portion 116” may be in the shape of a notch or recess. In all cases, the end portion 116” ” of the hook portion 116 is adapted to abut against a rear side of the rack 10 (i.e. the side facing away from the operator when installing the arrangement 200, i.e. the side where the sensitive electronics are hidden) when installed.

All parts of the arrangement 200 described above may be of metal, wood, steel and/or composite materials. Regarding the dimensions of the door assembly, it is preferably rectangular shaped and about 19 inches broad. More preferably, its width is at least the width of the rack 10. The length of the fastening means 110-113 depends on whether or not it is telescopically extendable. However, the size of the edge portion 116” is in the same range as the size of the mounting hole 2. Some excess width of the engagement part 115 is needed to allow the hook portion 116 to remain attached to the rack 10 when secured by the securing means Figs. 6-7 illustrates embodiments of a fastening means 110-113. The engagement part 115 may be arranged to any one of the plurality of mounting holes 2 in the rack 10. This allows for a modular flexible principle as the fastening means 110-113 can be arranged at different positions on the rack 10. Put differently, the size and positioning of the frame 100 in relation to the rack depends on the availability of mounting holes 2 on the rack 10. Moreover,since the fastening means 110-113 is movable sideWays (horizontally) along the top section 142 and the bottom section 144 of the frame, the adaptability of the arrangement 200 according to the invention is further proven.

In other Words, the arrangement 200 is adaptable to fit different types of racks 10. More importantly, the inner frame 100 is extendable vertically. The arrangement is also modular.
