This will be discussed morein detail with reference to Figs. 3 and 4a-c.

The top section 142 and the bottom section 144 are each arranged withtwo fastening means 110, 111, 112, 113. The top section 142 is arranged with onefastening means 110 close to the first end portion 142a and one fastening means111 close to the second end portion 142b. The bottom section 144 is arrangedwith one fastening means 112 close to the first end portion 144a and onefastening 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 isarranged on the bottom sectionThe fastening means 110-113 extends in a direction separated from thedirection 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 thelongitudinal (Vertical) extension of the bracket section 120 and the side section130, 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 fasteningmeans 110-113 in a horizontal manner along the length of the top section 142 andthe bottom section 144. Moreover, the inner frame 100 is telescopicallyadjustably up and down in a vertical direction by sliding the top section 142 andthe bottom along the bracket section 120 and the side section 130. The innerframe also has at least two fastening means 110-113 or “table legs” forconnection 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 frame100, thus allowing horizontal adaptation to the rack 10 during assembly. Asillustrated by the horizontal arrows in Fig. 2, the fastening means 110-113 ismovable in relation to the inner frame 100 and thereby adaptable to the size ofthe rack 10 onto which it is connectable. The fastening means 110-113 allows foran easy installation process where no tools are needed. Moreover, the fasteningmeans 110-113 is arranged such that only front access of the rack 10 is neededduring installation of the arrangement 200 onto the rackFig. 3 shows an embodiment of an arrangement 200 being attached to arack 10. The frame 100 has a bracket section 120 relative to which the remainingportions ofthe frame may be extended and/or adapted in a vertical direction. Theframe 100 may be of fixed-length. In other words, the top section 142 and thebottom section 144 is configured to be movable in order to adapt the size of theframe 100. The bracket section 120 typically has a fixed length whichcorresponds to the height of the door assembly 190. The height ofthe doorassembly 190 substantially corresponds to the distance between the top section142 and the bottom section 144 of the frameThe top section 142 and bottom section 144 are movable in a directioncorresponding to the length of the bracket section 120. This direction issubstantially vertical as seen in for instance Fig. 2. Similarly, the top section 142and bottom section 144 are movable in a direction corresponding to the length ofthe side section 130. When the inner frame 100 ofthe arrangement 200 isattached to the rack 10, the direction of movement would be perceived assubstantially vertical. For instance, the top section 142 and bottom sectionare 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 thelike.

Typically, the top section 142 may be movable between an upper endposition - at a level corresponding to the top ofthe door assembly 190 - and acenter position of the door assembly 190. Similary, the bottom section 144 maybe movable between a lower end position - at a level corresponding to the bottomof the door assembly 190 - and a center position ofthe door assembly 190. Boththe top section 142 and the bottom section 144 extend substantially horizontallybetween the vertically arranged 120 and 130 when mounted onto the rackThe top section 142 and the bottom section 144 are movably attachableto the bracket section 120 and the side section 130 in the way described above atboth oftheir respective end portions 142a-b and 144a-b. For instance, the endportions of the top section 142a-b and the bottom section 144a-b comprise anelongated slit 160 in which the fixation means 161 can run and be fixed. The topsection 142 and the bottom section 144 may then be fixedly attached to thebracket section 120 and the side section 130 at a desired position, by screwingthe fixation means 161. The slit 160 in the first and second end portions 142a-band 144a-b of the top section 142 and bottom section 144 may also be replacedby holes arranged with a distance from one another.

Preferably, corresponding slits 121 and 131 are present on the bracketsection 120 and side section 130, respectively. This way the fixation means 161can be run through both the slits ofthe top section 142 and the bottom sectiontogether with both the slits 121, 131 ofthe bracket section 120 and the sidesection 130, respectively.

Now turning to the Figures 4a-c illustrating an embodiment of anarrangement 200. As previously described, the arrangement 200 comprises a doorassembly 190. The door assembly 190 comprises a fastening section 195, a firstsection 196, a second section 197 and a third section 198.

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

The fastening means 110 each has a first end ll0a and a second end110b. Once the inner frame 100 is assembled onto the rack 10, the second end ofthe fastening means 110 is facing the rack 10 and the first end is facing the doorassembly 190 (once it is assembled onto the inner frame 100). The same appliesto the other fastening means 111, 112 andEach fastening means 110-113 comprises an engagement part 115 and asecuring part 114. The engagement part 115 is arranged on the second end oftheprotruding part 110-113. The engagement part 115 may comprise a hook shapedportion 116 (as shoWn in Figs. 6-7). The engagement part 115 is configured to beinserted in a mounting hole 2 of the rack 10, as illustrated in Fig. 3. Optionally,the fastening means 110-113 ofthe inner frame 100 does not comprise a hookshaped portion 116. In that case one can use a traditional acorn nut or cap nutWhen fastening or securing the inner frame 100 to the rackThe securing part 114 is arranged on the first end ll0a of the fasteningmeans 110-113. The securing part 114 is configured to secure the engagementpart 115 in the mounting hole 2 ofthe rack 10. The securing part 114 maycomprise an elongated element 118, 118” that at least partly extends along aninner part of the fastening means or protruding part 110-113. The elongatedelement 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 adjustmentmeans 117 is configured to fasten the engagement part 115 in the mounting hole2 ofthe rack 10. The adjustment means 117 may be a Wingnut or the like. TheWingnut provides a good grip for the thumb and finger and allows for tighteningthe fastening means 115 Without using any tools. Optionally, the adjustmentmeans 117 may be another type of nut, such as an acorn nut or cap nut. Othertypes of nuts are possible as Well. The fastening means 110-113 Will be discussedmore in detail With reference to Figs. 6-Figs 5a-c shoWs an embodiment of an arrangement 200, Where details ofthe fastening means 110-113 are shown in detail in Figs. 5b-c. In thisembodiment the fastening means 110 is arranged With a clamping plate 119. Theclamping plate 119 comprises an opening 119a arranged to receive the elongatedelement 118, 118” and the adjustments means 117. If a clamping plate 119 isused, it is thus arranged in conjunction With the securing part 114 ofthefastening 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 thesecuring part 114. This recess 151 may also be regarded as a slit Which extendsalong a transverse Width W ofthe fastening means. The top section 142 andbottom section 144 are configured to be movable or run in this recess 151, in adirection perpendicular to the length L ofthe fastening means 110-113. One canalso regard this as such that the inner frame 100 is Wedged into the recess 151 orslit and that the inner frame 100 extends transversely through each fasteningmeans 110-In the embodiment shown in Figs. 6a-b, the second end 110b ofthefastening means 110-113 comprises a tapered portion 152. The tapered portion152 is configured to be inserted inside the mounting hole 2 of the rack 10.Alternatively, the tapered portion 152 is first fastened to an adapter plate Withquadratic mounting holes. AfterWards, the adapter plate may be fastened to therack 10 by fasteners, such as for instance a Wingnut.

When tightening the fastening means 110-113 With the adjustment means117, an edge portion 116” ofthe hook shaped portion 116 (ofthe engagement part 115) comes into abutment against the front side ofthe rack 10, i.e. on the sidefacing the user during installation of the frame 100. Eventually, enoughresistance is achieved with the force directed by the adjustments means 117 ontothe rack 10 such that the frame 100 is held securely in place. The installer willexperience the resistance as he or she screws the adjustment means tightertowards the rack 10. Notably, the hook and wingnut fasteners, i.e. the fasteningmeans 110-113, are moveably connected to the frame allowing horizontaladaptation to the rack.

The shell cover 150 encompassing the interior ofthe fastening means110-113 may be displaceable in the lengthwise direction ofthe fastening means.Put differently, when the engagement part 115 has been inserted into themounting holes 2 of the rack 10 and upon tightening of the adjustment means117, the shell cover 150 will move in the same direction ofthe adjustmentmeans, namely towards the rack 10. This will cause the edge portion 116” tocontact a portion surrounding the respective mounting hole 2 on the front of therack 10. Meanwhile, an end portion 116” ofthe engagement part 115 is incontact with a rear side of the rack 10. By “front side ofthe rack” is meant theside facing the installer. The side where the fiberoptic cables are situated orhidden is called the rear side. One can interpret the rack 10 as a metaphoricaldoor frame of a house. In that case, the front side ofthe rack would correspondto the outside of the house.

The cover 150 may be arranged with a clamping pin 153. The clampingpin 153 may be of a 10 mm dimension, but other dimensions are possible as isknown from a person skilled in the art.

The tapered portion 152 on the second end 110b ofthe fastening means110 can be used to assist in sliding the fastening means into place. One can saythat the tapered portion 152 acts as a guide that leads the edge portion 116” ofthehook shaped portion 116 into contact with the rack 10. Please note that thisprinciple applies to the rest of the fastening means 111, 112 and 113 alsodisclosed 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 substantiallylongitudinal element with a fixed length. Optionally, the fastening means has aVariable length. It may also be telescopically displaceable along a longitudinalportion (or length L) thereof. Preferably, the length L ofthe fastening means 110-113 corresponds to at least the transverse width ofthe bracket section 120 andthe side section 130 ofthe inner frame 100. The length L may be in the range of70-85 mm, and more preferably in the range of 78 mm. The length of the bodyL1 may be in the range of 40-55 mm, and more preferably around 46 mm.

The transverse width W ofthe fastening means may be in the range of10-18 mm, and more preferably around 14-16 mm. The length ofthe recess Rmay 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 shellcover 150 on an inside ofthe fastening means 110-113. Optionally, the elongatedelement is fixedly attached to the shell cover 150 of the fastening means 110-113at an interior part 154 thereof. The attachment ofthe elongated element 118, 118”to the interior part 154 may for instance be through welding of the two parts. Ifthe elongated element 118, 118” is movable 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 directiontowards the front of the rack 10 as a result of an internal engagement ofelongated element 118, 118” and the inside part 154 ofthe shell cover 150. If theelongated 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 directiontowards the front of the rackIt should be noted that the adjustment means 117 together with theelongated element 118, 118” are adapted to lock or secure both the frame 100 andthe hook portion 116 together. Further, the elongated means 118 is adapted tosecure the horizontal or sideways movement of the inner frameFig. 7c shows the fastening means 110-113 according to anotherembodiment. Here, the hook portion 116 is formed by bending the engagementpart 115 to form the shape of a hook. In this embodiment there is a substantiallysmooth transition between the end portion 116” of the hook portion 116 and therest of the engagement part 115. Alternatively, the hook portion 116 may beshaped by cutting out material in the end portion 116” of the engagement part115. 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 rearside ofthe rack 10 (i.e. the side facing away from the operator when installingthe 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 doorassembly, it is preferably rectangular shaped and about 19 inches broad. Morepreferably, its width is at least the width ofthe rack 10. The length ofthefastening means 110-113 depends on whether or not it is telescopicallyextendable. However, the size ofthe edge portion 116” is in the same range as thesize ofthe mounting hole 2. Some excess width ofthe engagement part 115 isneeded to allow the hook portion 116 to remain attached to the rack 10 whensecured by the securing meansFigs. 6-7 illustrates embodiments of a fastening means 110-113. Theengagement part 115 may be arranged to any one of the plurality of mountingholes 2 in the rack 10.
