With reference to Figs. 3 and 4, it may be defined that the first attachment 122 ismovable in relation to the stop 116 between a first position (shown in Fig. 3)proximal, for example close, to the stop 116 and a second position (shown in Fig.4) distal to the stop 116. lt may be defined that in the second position, which isshown in Fig. 4, the first attachment 122 is located further away from the stop 116compared to when the first attachment 122 is in the first position, which is shown inFig. 3. For example, when the interface 112 is attached to an underside of an over-head structure, for example to the ceiling 108 of a building, the first position (Fig. 3)may be defined as a lower position of the first attachment 122 and the secondposition (Fig. 4) may be defined as a top position of the first attachment 122 inrelation to the stop 116 or the ground. With reference to Figs. 3 and 4, in the shownembodiment, the first attachment 122 may be urged from the second position (Fig.4) toward to the stop 116 and to the first position (Fig. 3) by way of gravity. 17 With reference to Figs. 3 and 4, when being pushed, i.e. when the push section 126is pushed, in the direction 129 toward the interface 112, and for example away fromthe stop 116, the push section 126 is configured to pull, and/or move, the firstattachment 122 away from the second attachment 124 so as to separate the firstattachment 122 from the second attachment 124. When the first attachment 122 isseparated from the second attachment 124, the device 102 is detached from itsattachment to the section 104 of the structure 106 provided by the apparatus 100.For example, it may be defined that the first attachment 122 is pu||ed away from thesecond attachment 124 when the first attachment 122 is moved, or pu||ed, from thefirst position (shown in Fig. 3) to the second position (shown in Fig. 4) by the pushingof the push section 126 in the direction 129 toward the interface 112.

For example, a tool 130 as shown in Figs. 40 to 42 may be used to detach or releasethe device 102 from its attachment to the section 104 of the structure 106 via theapparatus 100. The tool 130 may also be used to attach the device 102 to theapparatus 100 and to the section 104 of the structure 106. The tool 130 may be ahand-held tool 130. The tool 130 may be used by a user or operator standing on afloor or the ground, or standing elsewhere. With reference to Figs. 40 to 42, the tool130 has a head 132 which includes a holder 134. The holder 134 may include aholder plate 136. Further, the head 132 may include a driver 138, for example anarched driver 138. The holder 134 is movable in relation to the driver 138 by way ofguides 140 of the head 132 between at least a first position (see Fig. 41) and asecond position (see Fig. 40). With reference to Fig. 41, in the first position theholder 134 is set with a greater distance to the driver 138 compared to when theholder 134 is set in the second position shown in Fig. 40. When the holder 134 isset with the greater distance from the driver 138 as shown in Fig. 41, a basket 142is formed for catching a detached device 102. The guides 140 may also bedescribed as spacers for spacing the holder 134 from the driver 138, especiallywhen the holder 134 is in the first position (see Fig. 41).

With reference to Figs. 40 to 42, the tool 130 may include a rod 144 to which thehead 132 may be attached. The entire rod 144 is illustrated in Fig. 42. The rod 144 18 may be a telescopic rod, whereby the length or the longitudinal extension of the rod144 is adjustable and may for example be extended to 2 to 8 meters, for example.

When the holder 134 is set with the greater distance to the driver 138 as shown inFig. 41 (the first position), the driver 138 is configured to contact the push section126 and may push, or drive, the push section 126 in the direction 129 toward theinterface 112 so as to separate the first attachment 122 from the second attachment124, whereby the device 102, which is attached to the second attachment 124, isdetached from its attachment to the section 104 of the structure 106 (via theapparatus 100), and the device 102 may be caught by the formed basket 142 of thehead 132. Further, when the holder 134 is set with the smaller distance from thedriver 138 as shown in Fig. 40 (the second position), the holder 134 may be used tohold the device 102 so as to attach the device 102 to the section 104 of the structure106 via the apparatus 100 and via the first and second attachments 122, 124.However, it should be understood that several alternative tools instead of the tool130 shown in Figs. 40 to 42 may be used to attach and/or detach the device 102to/from the section 104 of the structure 106 (and/or to/from the apparatus 100). Forexample, the driver 138, the holder 134 and the guides 140 of the head 132 may be given several alternative designs.

With reference to Figs. 1 to 5, it may be defined that the push section 126 has oneor more contact surfaces 146 for contact with a tool, for example a tool 130 asdisclosed above in connection with Figs. 40 to 42. l\/lore specifically, the contactsurface 146 of the push section 126 may be configured for contact with the driver138 of the head 132 of the tool 130 disclosed above, or the driver of any other tool.The push section 126 may be configured such that the contact surface 146 isdislocated, or displaced, or placed with a distance, from the first attachment 122when viewed in the direction 129 toward the interface 112. The annular section 128of the push section 126 may be provided with the contact surface 146.

With reference to Figs. 3 and 4 again, it may be more specifically defined that whenbeing pushed, i.e. when the push section 126 is pushed, in the direction 129 towardthe interface 112, the push section 126 is configured to pull the first attachment 122 away from the stop 116 so as to separate the first attachment 122 from the second 19 attachment 124. Further, even more specifically, it may defined that when beingpushed in the direction 129 toward the interface 112, the push section 126 isconfigured to pull the first attachment 122 away from the stop 116 toward theinterface 112 so as to separate the first attachment 122 from the second attachment124. lt may even be defined that when being pushed in the direction 129 toward theinterface 112, the push section 126 is configured to pull the first attachment 122away from the stop 116 toward the interface 112 so as to separate the firstattachment 122 from the second attachment 124 while the device 102 abuts, directlyor indirectly, against the stop 116. Thus, it may be described that the stop 116 viaits direct or indirect abutment with the device 102, for example via its abutment withthe second attachment 124 attached to the device 102 or with an intermediatemember, which in turn holds the device 102, is configured to prevent the secondattachment 124, which may be attached to the device 102, from following the firstattachment 122 when the first attachment 122 is pulled away from the stop 116 toward the interface 112.

With reference to Figs. 3 to 5, the first attachment 122 may be attached to the pushsection 126. For example, the first attachment 122 may be indirectly, or directly,attached to the push section 126. The first attachment 122 may be fixedly attachedto the push section 126. The unit 120 may include a second member 148 holdingthe first attachment 122. The second member 148 is at least partly movable inrelation to the stop 116. The second member 148 may be configured to be situatedbetween the stop 116 and the interface 112. The second member 148 may beattached to the push section 126. For example, the second member 148 may befixedly attached to the push section 126, for example as shown in Figs. 3 to 5. lnother embodiments, the second member 148 may be detached from, i.e. notattached to, the push section 126, which, for example, will be disclosed hereinbelow.ln the embodiment shown in Figs. 1 to 7, since the entire unit 120 is movable inrelation to the stop 116, so is the second member 148, which is included in the unit120. Thus, in the embodiment shown in Figs. 1 to 7, the entire second member 148is movable in relation to the stop 116. With reference to Figs. 4 and 5, the secondmember 148 may have, or may form, one or more openings 149 for the spacer 114or spacers 114, for example three openings 149 for the three spacers 114.

With reference to Fig. 4, the opening 149 of the second member 148, which ismentioned above, and/or the spacer 114 may provide, or include, a first guide 153for guiding the second member 148, or the unit 120, in relation to the member 110and/or the stop 116, for example when the second member 148 and/or the unit 120is moved in relation to the stop 116 and/or the spacer 114. Alternatively, or inaddition thereto, and with reference to Fig. 5, the push section 126 may provide, orinclude, a second guide 150 for guiding the second member 148, or the unit 120, inrelation to member 110, such as in relation to the stop 116, for example in relationto the plate 118. l\/lore specifically, the push section 126 and the plate 118 mayprovide the second guide 150, which also may be configured to guide the pushsection 126 in relation to the stop 116, for example in relation to the plate 118. Thesecond guide 150 may include an inner surface 151, for example an inner surface151 of the push section 126.

The first embodiment illustrated in Figs. 1 to 7, may be supplemented with a biasingelement, i.e. the apparatus 100 may include a biasing element. The biasing elementis configured to urge the first attachment 122 in a direction 155 away from theinterface 112, for example toward the stop 116, especially when the first attachment122 is displaced, or dislocated, from its first position. The biasing element may besituated between the interface 112 and the first attachment 122, or between theinterface 112 and the second member 148. The biasing element may thus, forexample, be a compression spring. However, other types of biasing elements arepossible. ln alternative embodiments, the biasing element may be situated betweenthe first attachment 122 and the stop 116, or between the second member 148 andthe stop 116, and may thus for example be an extension or tension spring. However,other types of biasing elements are possible. The biasing element may comprise anelastic element (e.g. a spring), or a resilient element, and may therefore be referred to herein also as a spring element or resilient element.

With reference to Figs. 8 to 15, a second embodiment of the apparatus 200 fordetachably attaching a device 202 (see Figs. 14 and 15) to a section 104 of astructure 106 (see Fig. 6) according to the first aspect is schematically illustrated.The second embodiment shown in Figs. 8 to 15 corresponds in several aspects tothe first embodiment shown in Figs. 1 to 7, so only some of the differences between 21 the second embodiment and the first embodiment wiii be mentioned herein. insteadof three first attachments, the apparatus 200 according to the second embodimenthas only one first attachment 222 heid by the unit 220, or, in the shown embodiment,more specificaiiy heid by the second member 248 of the unit 220. As mentionedabove, the unit 220 inciudes the push section 226. in the shown embodiment, thefirst attachment 222 inciudes a magnet 223, and is centraiiy iocated in reiation tothe piate 218 of the stop 216 of the member 210. Thus, in the shown embodiment,the piate 218 oniy has, or forms, a singie opening 227, iocated centraiiy at the piate218. With reference to Fig. 15, the second attachment 224, which inciudes theferromagnetic materiai 225, for exampie a ferromagnetic materiai item, is circuiarand disc-shaped. it is to be understood that the first and second attachments 222,224 may have other configurations and designs instead of a magnet 223 and aferromagnetic materiai 225, for exampie as disciosed above or beiow in connectionwith the other embodiments. The member 210 of the second embodiment oniyinciudes two spacers 214, the spacer 214 being provided with the interface 212.Thus, with reference to Fig. 12, the second member 248 oniy needs to form twoopenings 249 for the two spacers 214. With reference to Figs. 14 and 15, in theshown embodiment, the device 202 inciudes a ioop 252, on which any kind of itemmay be hanged. However, other devices are possibie.

With reference to Figs. 16 to 23, a third embodiment of the apparatus 300 fordetachabiy attaching a device 102 to a section 104 of a structure 106 (see Figs. 6and 7) according to the first aspect is schematicaiiy iiiustrated. The thirdembodiment shown in Figs. 16 to 23 corresponds in severai aspects to the firstembodiment shown in Figs. 1 to 7, so oniy some of the differences between the thirdembodiment and the first embodiment wiii be mentioned herein. With reference toFigs. 18 to 20 and 23, the second member 348 hoiding the first attachment 122 isdetached from the push section 326 of the unit 320, i.e. the second member 348and the first attachment 122 are not attached to the push section 326. The unit 320is at ieast partiy movabie in reiation to the stop 316.

With reference to Figs. 18 to 20 and 23, the second member 348 is fiexibie. Forexampie, the second member 348 may be made of a fiexibie materiai, such as apoiymer, a poiymer mixture, a metai, or a metai aiioy. The second member 348 may 22 be configured to urge the first attachment 122 in a direction 155 away from theinterface 112 and/or toward the stop 116, especially when the first attachment 122is displaced, or dislocated, from its first position. Thus, it may be defined that thesecond member 348 forms a biasing element 348 or biasing member configured tourge the first attachment 122 in a direction 155 away from the interface 112, forexample toward the stop 116, especially when the first attachment 122 is displaced,or dislocated, from its first position. With reference to Fig. 20, the second member348 may be attached to the member 1 10, for example to the stop 116 of the member110, for example to the plate 118 of the stop 116. The attachment of the secondmember 348 to the member 110 may be provided by any kind of suitable means ofattachment 357 or connection, for example a pin, glue, a screw, or a snap-onconnection etc. Thus, the second member 348 is partly, and not completely,movable in relation to the stop 316. Expressed alternatively, the entire secondmember 348 is not movable in relation to the stop 316.

With reference to Figs. 20 and 23, the second member 348 may have a Y-shape.The second member 348 may include three arms 354. However, in alternativeembodiments, for example, the second member 348 may include two arms 354instead of three arms 354, i.e. one arm 354 may be excluded. Each arm 354 mayhold the first attachment 122, or one 122 of the first attachments 122. With referenceto Figs. 18, 19 and 21, the push section 326 may have a notch 356 or recess, forexample an annular notch 326. The notch 356 may hold the second member 348.l\/lore specifically, the notch 356 may hold the arms 354 of the second member 348,or more specifically, may hold an outer edge portion 358 of each arm 354. Fig. 18shows the first attachment 122 in its first position. The second member 348 may beconfigured to urge the first attachment 122 to the first position. The outer edgeportion 358 may be described to be movable in relation to a centre portion 360 ofthe second member 348, which for example is made possible because of theflexibility of the second member 348. By the engagement of the outer edge portion358 into the notch 356, the second member 348 may also be configured to urge thepush section 326 away from the interface 112 to move the first attachment 122 to its first position shown in Fig. 18. 23 When the first attachment 122 is in its first position as shown in Fig. 18, the firstattachment 122 can be detachably attached to the second attachment 124. Thesecond attachment 124 associated with the third embodiment of the apparatus 300may correspond to the second attachment 124 illustrated in Fig. 7. ln Fig. 19, thefirst attachment 122 has been pulled to its second position by the pushing of thepush section 326, which pushes the outer edge portion 358 of each arm 354 toward the interface 112 by way of the notch 356.

With reference to Figs. 24 to 32, a fourth embodiment of the apparatus 400 fordetachably attaching a device 402 (see Fig. 32) to a section 104 of a structure 106(see Fig. 6) according to the first aspect is schematically illustrated. The fourthembodiment shown in Figs. 24 to 32 corresponds in several aspects to the firstembodiment shown in Figs. 1 to 7, so only some of the differences between thefourth embodiment and the first embodiment will be mentioned herein.

With reference to Figs. 25, 26, 29 and 32, the unit 420 may include three firstattachments 422. ln the shown embodiment, one 422, 424 of the first and secondattachments 422, 424 includes a protrusion 462 while the other one 422, 424 of thefirst and second attachments 422, 424 includes a recess 464 (see Fig. 32) forreceiving the protrusion 462. More specifically, in the embodiment shown in Figs.24 to 32, the first attachment 422 includes the protrusion 462 while the secondattachment 424 includes the recess 464 (see Fig. 32). The recess 464 shown in Fig.32 may be annular or ring-shaped.

With reference to Figs. 28 and 29, in the shown embodiment, the second member448 of the unit 420, which holds the first attachment 422, is attached to the pushsection 426 For example, the second member 448 may be fixedly attached to thepush section 426. The unit 420 may be at least partly flexible. The second member448 may be flexible. For example, the unit 420 and/or the second member 448 maybe made at least partly of a flexible material, such as a polymer, a polymer mixture,a metal, or a metal alloy. With reference to Fig. 29, the second member 448 mayinclude an arm 466 for each first attachment 422, wherein the arm 466 is configuredto carry the first attachment 422, i.e. the protrusion 462 in the shown embodiment.ln the shown embodiment, the second member 448 includes three arms 466. 24 However, in alternative embodiments, for example, the second member 448 mayinclude two arms 466 instead of three arms 466, i.e. one arm 466 may be excluded.

With reference to Figs. 24, 27, 28 and 31, the member 410 may include, or mayform, a depression 468, for example in the form of a compartment, in which the firstattachment 422 is detachably attachable to the second attachment 424. Themember 410 and/or the depression 468 may have a wall 470, and/or the depression468 may be defined or limited by a wall 470. With reference to Fig. 31, the wall 470may have, or may form, an opening 472 for each first attachment 422, i.e. eachprotrusion 462 in the shown embodiment. With reference to Figs. 27, 28 and 29, thewall 470 may be attached to a floor or a base 473. The wall 470 and the base 473may together form or define/limit the depression 468. However, in alternativeembodiments, the base 473 may be excluded. With reference to Fig. 32, the secondattachment 424 may be provided on a projection 475. The projection 475 and thesecond attachment 424 may be insertable in the depression 468. ln the shownembodiment, the plate 418 of the member 410 forms one opening 427, which alsois the opening 427 or mouth of the depression 468.

With reference to Figs. 25 and 26, the protrusion 462 is configured to extend throughthe opening 472 of the wall 470. With reference to Figs. 25 to 28, in the shownembodiment, the first attachment 422 may be movable in a first direction 474 whichis transverse to the direction 129 toward the interface 412. l\/lore specifically, eachfirst attachment 422, for example the protrusion 462, may be movable in its own firstdirection 474 which is transverse to the direction toward 129 the interface 412. Whenthe push section 426 is pushed in the direction 129 toward the interface 412, thepush section 426 may be configured to pull the first attachment 422, for example theprotrusion 462, in the first direction 474 so as to separate the first attachment 422from the second attachment 424. The first attachment 422, for example theprotrusion 462, may also be movable in a second direction 476 opposite to the firstdirection 474.

With reference to Figs. 25 and 26, the first attachment 422, for example theprotrusion 462, is illustrated in a position when it would engage the secondattachment 424, for example the recess 464, and thus lock the second attachment 424 to the member 410, or stop 416, and also lock the projection 475 in thedepression 468, and thus also lock the device 402 to the member 410, the stop 416and/or to the apparatus 400, since the second attachment 424 may be attached tothe device 402, for example via the projection 475. ln some embodiment, theprojection 475 may be the device 402, or the device 402 may be an item attachedto the projection 475.

With reference to Figs. 27 to 29, the first attachment 422, for example the protrusion462, is illustrated in a position when it has disengaged the second attachment 424,for example the recess 464, and thus unlocked the second attachment 424 from themember 410, or stop 416, and also unlocked the projection 475 from the depression468, and thus also unlocked the device 402 from the member 410, the stop 416and/or the apparatus 400. The disengagement of the first attachment 422, forexample the protrusion 462, from the second attachment 424, for example therecess 464, is effected by the pushing of the push section 426 in the direction 129toward the interface 412, since, as stated above, the push section 426 is configuredto pull the first attachment 422, for example the protrusion 462, in the first direction474, which is a direction away from the second attachment 424.

With reference to Figs. 26 and 28, the flexibility of the unit 420 may urge the pushsection 426 in a direction 155 away from the interface 412, for example toward thestop 416, especially when the protrusion 462 has exited the depression 468, andthus urge or return the protrusion 462 into the depression 468. lt may be definedthat the arm 466 is configured to urge the first attachment 422 in the second direction476 and/or into engagement with the second attachment 424 when located in thedepression 468. lt may be defined that the arm 466 is configured to urge the pushsection 426 in a direction 155 away from the interface 412, for example toward the stop 416, especially when the protrusion 462 has exited the depression 468.

With reference to Figs. 26 and 28, it may be defined that the unit 420 and/or thesecond member 448 are/is configured to urge the first attachment 422 in the seconddirection 476, especially when the first attachment 422 is displaced, or dislocated,from the depression 468. Thus, it may be defined that the unit 420 and/or the secondmember 448 form/forms a biasing element 448 or biasing member configured to 26 urge the first attachment 422 in the second direction 476, especially when the firstattachment 422 is displaced, or dislocated, from the depression 468 and/or from its engagement with the second attachment 424.

With reference to Figs. 33 to 39, a fifth embodiment of the apparatus 500 fordetachably attaching a device 502 (see Fig. 39) to a section 104 of a structure 106(see Fig. 6) according to the first aspect is schematically illustrated. The fifthembodiment shown in Figs. 33 to 39 corresponds in several aspects to the firstembodiment shown in Figs. 1 to 7, so only some of the differences between the fifthembodiment and the first embodiment will be mentioned herein.

With reference to Figs. 33 to 37 and 39, one 522, 524 of the first and secondattachments 522, 524 may include a protrusion 578 while the other one 522, 524 ofthe first and second attachments 522. 524 may include a recess 580 for receivingthe protrusion 578.
