[0057] FIG. 9 illustrates, in a view from outside, one completed reading carrel for RFID tags.

[0058] Constructions used in connection with a mounting frame 1 of the invention for a vertical support 14. a mounting frame-encircling base 12, a top support 13, a door frame support 15, and wall elements 31 of walls 3 are illustrated in FIGS. 1A-1B, 2A-H, 2K, 2L, 3A-3B, 4A-4C, 5, as well as 6.

[0059] These basic constructions of the mounting frame 1 enable assembly of various reading carrels for RFID tags as depicted in FIGS. 7A-7B, 8A-8D, and 9.

[0060] Hereinafter is first described, schematically by way of FIGS. 1A-1B and 2A-2H, 2K, 2L, constructions as well as sealing options for the mounting frame 1 and wall elements connected therewith.

[0061] In FIGS. 2A and 2B is illustrated with two section views, respectively, the construction of two similar type sealings either

[0062] a) by placing a gasket 7 between a channel beam (120, 130 or 140) and a wall element 31 or

[0063] b) by placing a gasket 7 between a wall element 31 provided with a channel 311 and a web 13g extending from a beam 13 (vertical support).

[0064] The exemplary sealing visible in FIG. 2A is constructed by placing the gasket 7 between a U-channel 12a of the base 12 comprising a channel beam and a bottom end of the wall element 31 fitted in this U-channel 12a. A similar type sealing can also be constructed by installing a gasket between a U-channel of the top support 13 comprising a channel beam and a top end of the wall element 31 or between a U-channel of the vertical support 14 and an end face of the wall element 31. As evident from FIG. 2A, the gasket is usually placed between a bottom end of the wall element 31 adjoining the lower end face thereof and just one of the channel flanges of the U-channel in a base segment.

[0065] The exemplary sealing visible in FIG. 2B is constructed between a web 13g directed downward from the beam of the top support 13 and a horizontal channel 31a extending at a top end of the wall element 31 co-directionally with the top end of the wall element 31, said horizontal channel opening upward. The top support 13 has its web 13g brought to the proximity of a channel base 31c of the horizontal channel 31a at the top end of the wall element 31. The gasket 7 is placed between a channel flange 31d; 31d and the web 13g, the former extending upward from the horizontal channel's channel base 31c. An exactly similar type sealing can likewise be constructed between a web 12g directed upward from a base segment of the base 12 and a horizontal channel 311 included in a bottom end of the wall element 31 and opening downward, or between a web directed sideways from a vertical support 14 co-directionally with the vertical support and an end channel 311 included in an end face of the wall element 31 and opening sideways.

[0066] FIG. 1B illustrates one way of placing a gasket 7 on a channel beam 140, said channel beam 140 being then usable for constructing the sealing of FIG. 2A between the channel beam 140 and the bottom end 31 of a wall element as subsequently described.

[0067] In FIG. 1B is shown (in a view from behind) a channel beam 140 that can be used as a vertical support 14. From below a bottom edge of the channel beam 140 extends an end adapter 8; 80 directed downward in FIG. 1B and being narrower than the rest of the beam body. The illustrated channel beam 140 is capable of being rested by way of a bottom end bearing surface 80a of its end adapter 80 against a channel base 12c of the base segment's channel beam 120 as depicted in FIG. 1A.

[0068] The vertical support 14 visible in FIG. 1B consists of a channel beam 140 having its U-shaped channel 14a (U-channel) made up of a channel base 14c both lengthwise sides of which are provided with a channel flange 14; 14d and 14; 14d pointing away from the channel base 14c. Each channel flange 14; 14d and 14; 14d of the vertical support 14 extends away from the channel base 14c of the U-channel 14a at an angle of about 90 degrees, whereby the plane extending by way of each channel flange 14; 14d and 14; 14d is transverse relative to the direction of the channel base's 14c plane.

[0069] In FIG. 1A is shown a channel beam 140 of FIG. 1B (vertical support 14), including a U-channel 14a. This U-channel 14a connects to the base 12 by way of an adapter 8. The adapter 8 comprises an inner adapter 8; 90 for the vertical support 14 and an end face adapter 8; 80a joining seamlessly with the inner adapter. The end face adapter 8; 80a is rested against a channel base 12c of the channel 12a in the mounting frame's base 12.

[0070] In FIG. 1A, it is only along one of the two channel flanges 14d; 14d of the vertical support 14 that, co-directionally with the channel base 14, i.e. in vertical direction, extends a continuous EMC gasket 7; 7a, which is approximately equal in length to said channel flange 14; 14d and which conducts electricity. The EMC gasket is suitably an aluminum strip.

[0071] The EMC gasket has an objective of sealing, as illustrated in FIG. 2A, a clearance left between a wall element 31 mountable on the vertical support 14 and a channel flange 14d of the vertical support's U-channel, such that the EMC gasket 7; 7a does not allow passage of radio-frequency radiation therethrough from inside to outside of the carrel or vice versa. As can be seen from FIG. 1A, once the vertical support 14 is rested by way of the end face adapter 8; 80 against the channel base 12c of the mounting frame's base 12, the vertically directed EMC gasket extends all the way to a channel flange 12d of the base 12. On this channel flange 12d is then installed its own EMC gasket in horizontal direction. It is for the purpose of simplifying the figure that seals for the channel 12c of the base 12 are omitted from FIG. 1.

[0072] Gaskets 7 for the channel 12c of the base 12, and the relationship thereof with gaskets 7 of the vertical support 14, are depicted i.a. in FIGS. 3A-3B and 4A-4B.

[0073] Thus, it is FIGS. 3A-3B and 4A-4B which depict more accurately an EMC gasket 7; 7a, which extends specifically along the mounting frame's base 12 co-directionally with a channel base 12c of one of its base segments, and which during installation comes into contact with the EMC gasket of the vertical support 14 (cf. FIG. 1A).

[0074] As can be seen, among others, from FIG. 3B, the gasket 7 thereby constitutes a continuous sealing strip 7, 7 extending from the channel 12a in a base segment of the base 12 to the channel 14a of a vertical support 14. The channel 14a of a vertical support 14 and the channel 12a of a base segment are in contact with each other by way of the channel flanges 14d, 12d thereof, which is why the sealing strip extends from the channel flange 12 of a base segment's channel to the channel flange 14d of a vertical support's 14 channel. The benefit gained by such a continuous sealing strip 7, 7 is its ability to prevent radio-frequency radiation from propagating across to the opposite side in spite of minor inaccuracies in the manufacturing tolerances of a wall element 31, a base 12 or a vertical support 14 or in spite of slightly out-of-alignment assembly of the base 12 and the vertical support 14, i.e. a deviation from their conventional position normal to each other.

[0075] FIGS. 2C-2E present various vertical webs 12g directed upward from a lengthwise plane 12h (horizontal plane) of a base segment of the frame 1.

[0076] FIGS. 2K and 2L, on the other hand, depict schematically assemblies made up jointly by a web and a channel in segments of the mounting frame's base 12, as well as in ceiling structures (top support 13) and in a vertical support 14.

[0077] In FIGS. 2C-2E are shown, in schematic section views, various webs 12g directed upward from a lengthwise plane 12h (horizontal plane) of a base segment of the frame 1. The webs 12g extend always perpendicularly to the horizontal plane 12h, which is parallel to a foundation on which the base segment is rested. A similar type web 12g may also be included in the top support 13, in which case it extends respectively from the top support and, at the same time, also from a plane of the ceiling perpendicularly downward as depicted in FIG. 2B. A similar type web 12g may also be included in the vertical support 14, in which case the web is vertical and directed sideways from a vertical plane defined by the vertical support 14, towards a base segment fastened to the vertical support 14.

[0078] In FIGS. 2K and 2L are respectively illustrated various channels extending in a top or bottom end of the wall element 31 or in an end face of the wall element 31 (cf. FIG. 2B). These can be respectively fitted with a web, an away-directed web connecting to a base segment 21, 22, 23, 24, a top support 13 or a vertical support 14, as presented above schematically in FIG. 2B as well as 2C-2E.

[0079] In FIG. 2K is presented how a vertical channel 411 extending in an end face of the wall element 31 can be fitted with a horizontal web 14g of the type shown in FIG. 2C, which protrudes from the vertical support 14. The joint depicted in FIG. 2K can be insulated by placing a seal between the web 14g and a channel flange of the channel 411 extending in an end face of the wall element 31.

[0080] FIG. 2L visualizes how a sealing constructed according to the invention is achieved in a joint which is established between vertical webs 12g, included in segments 121 and 122 of the mounting frame's 1 base 12, as well as wall elements 31; 31 and 31; 31. Each wall element 31; 31 and 31; 31 has its bottom end face 31f formed with a downward-opening channel 311; 311 and 311; 311 in which each web 12g; 12g or 12g; 12g, directed upward from a plane of the base's segment 121, 122, is capable of being accommodated. The wall elements 31; 31 and 31; 31 are visualized having been installed, by way of the horizontal channels 311; 311 and 311; 311 included in the bottom end face 31f thereof, respectively on two webs 12g; 12g and 12g; 12g rising upward from a plane of the base's 12 base segment 121, 122. The gap between these webs 12g; 12g and 12g; 12g as well as the horizontal channels 311 in the bottom end faces 31f of the wall element 31; 31 and 31; 31 is sealed with an EMC gasket 7, which in this case is an aluminum tape/strip.

[0081] In FIG. 2L is further shown an upward-opening horizontal U-channel 311; 311 and 311; 311 included in a top end of each wall element 31; 31 and 31; 31, more specifically in a top side 31d of the top end. These horizontal channels 311; 311 and 311; 311 at the top ends of the wall elements 31; 31 and 31; 31 are fitted with a top support 13 which has two webs 7 directed downward from a plane of this top support 13 (cf. also FIG. 2D). Between the web 13g; 13g or 13g; 13g, directed downward from a plane of the top support 13, and a vertical side of the horizontal channels 311; 311 and 311; 311 lies a horizontally extending EMC gasket 7; 7a.

[0082] The gasket 7; 7a is installed on that vertical side of a wall element's 31 horizontal channel which is closer to a reading carrel T and it extends in a continuous manner in a channel 311 of the wall element's 31 top end 31d as well as in a web 13g of the top support 13. When the channel 311 of the wall element's 31 top end 31d is fitted on the top support's 13 web 13g, the passage of radio-frequency radiation into the reading carrel T by way of the top support's channel 311 is prevented, for example from the side of an adjacent storage. Thus, the sealing strip made up of gaskets 7 extends continuously from a web 13g of the mounting frame's 1 top support 13 to a web 14g (not shown in the figure) of two side supports 14 connected to each top supports, and further to that web 12g of a base segment of the base 12 which comes into contact with these two side supports.

[0083] In FIGS. 3A-3B, 4A-4B is also illustrated vertical support pairs 14, 14 installed on segments of the mounting frame's 1 base 12 and having mouths 14b, 14b of the C-channel thereof opening at an angle of either 90 or 180 degrees relative to each other.

[0084] FIG. 4C, on the other hand, visualizes a corner of the mounting support's base 12, at which arrive two base segments 121, 122 at a right angle with each other.

[0085] FIG. 5 visualizes the construction of a vertical support 14 according to one preferred embodiment of the invention, having its vertical channel 14a provided with an adapter 8 for connecting said vertical support 14 to a horizontal channel 12a or 13a of the base 12 and/or the top support 13.

[0086] With these vertical support pairs 14, 14, adapters 8 of the vertical support 14, and segments of the base 12, illustrated in FIGS. 3A-3B, 4A-4B, 4C and 5, there is provided an ability to produce readily and quickly sealable constructions between the mounting frame 1 and the wall elements 31 and door jambs 15 installable thereon. These constructions will be described hereinafter and comprise couplings between interconnected vertical supports and base segments.

[0087] FIG. 4C visualizes how the segments 121 and 122 of the base 12 are coupled to each other in such a way that the bottom thereof extend in a common horizontal plane, yet the lengthwise directions thereof are at an angle of 90 degrees, i.e. at a right angle, relative to each other. The right angle between the base segments 121, 122 enables installation at an angle (corner) therebetween of a vertical support pair 14, 14 whose vertical channels 14a, 14a open at an angle of 90 degrees relative to each other as illustrated in FIGS. 3B and 4A.

[0088] A corner of the base 12, visible in FIG. 4C, is assembled from two base segments 121 and 122 of the base 12 by coupling the same to each other for a 90-degree angle. Each base segment 121, 122 of the base 12, and at the same time the entire base 12 as well, is made up of a channel beam 120. The channel beam 120 has its channel 12a made up of a channel base 12c whose both lengthwise sides are provided with channel flanges 12d; 12d and 12d; 12d directed away from the channel base, each extending in a direction which is transverse to that of said channel base 12c. Close to an upper edge of one of the channel beam's 120 channel flanges 12d; 12d extends a continuous elongated, strip-like gasket 7 manufactured from an electrically conductive material such as metal. The gasket 7 follows said upper edge of the channel flange 12d; 12d, extending thereby in a lengthwise direction of the channel base. The gasket 7 extends along the channel beam 120 preferably from end to end.

[0089] FIGS. 3B and 4A visualize a vertical support pair 14; 14 and 14; 14 already fitted in the channels 12a of two base segments 121, 122 of the base 12, said vertical supports having mouths 14b, 14b and 14b; 14b thereof opening at an angle of 90 degrees relative to each other. FIG. 3A shows, on the other hand, how the vertical support pair 14; 14 and 14; 14 is mounted on the base segments 121, 122 of the base 12 present at a 90-degree angle relative to each other. The base's segments 121, 122 are coupled to each other the same way as described above in reference to FIG. 4C.

[0090] FIG. 4B reveals, on the other hand, two vertical supports 14; 14 and 14; 14 installed in a channel 12a of a single base segment 121 of the base 12, with mouths 14b, 14b thereof opening at an angle of 180 degrees relative to each other. Such a vertical support pair 14, 14 is mounted on the middle part of a base segment and can be used for example as an interim support for the installation of a door 5 on the mounting frame's base segment so as to be subsequently illustrated in FIG. 7B.

[0091] The rear flanges of vertical support pairs 14; 14 and 14; 14 displayed in FIGS. 3A-3B as well as 4A-4B can be coupled to each other prior to installation. Each vertical support 14, 14 of the vertical support pair 14; 14 and 14; 14, made up of inter-connected vertical supports and presented in FIGS. 3A-3B as well as 4A-4B, consists of a channel beam 140 identical to that described above in reference to FIGS. 1A and 1B. The construction of a channel beam 120 of the base segments displayed in FIGS.

[0092] 3A-3B as well as 4A-4B, on the other hand, is identical to what has been more precisely described in reference to FIG. 4C.

[0093] FIG. 5 reveals the construction of a vertical support 14 according to one preferred embodiment of the invention, said vertical support being provided with an adapter for coupling the vertical support 14 to a base 12 and/or a top support 13. This has been demonstrated with two identical, longitudinally interconnected vertical supports 14; 14 and 14; 14 visible in FIG. 5, each of which is made up of a channel beam 140. The construction of channel beams 140; 140 and 140; 140 is identical to what has been described earlier in connection with FIG. 1A. Above a top edge of the lower part (or upper part) or a top end face 14f (of the lower part) of each channel beam 140; 14 and 140; 140 140 rises an end face adapter 80 visible in the figure. Said vertical supports 14; 14 and 14; 14 are connected to each other the same way as those illustrated in FIGS. 3A-3B as well as 4A-4B, whereby the first vertical support 14; 14 has the rear wall of its channel flange 14d coupled to the rear wall of the second vertical support's 14; 14 channel base 14c.

[0094] The end face adapter 80 is part of an adapter 8 already fixed to a channel 14a of the vertical support 14, whereby the vertical support 14 is attachable to the base 12. The adapter 8 includes an inner adapter, as well as the end face adapter 80 shown in the figure. The end face adapter protrudes from outer edges 14f, 14f of the end faces of a channel base 14c and channel flanges 14d, 14d of the channel 14a of a channel beam 140 employed as the vertical support 14 co-directionally with the channel 14a over a certain distance (protruding distance) 80h. The end face adapter 8; 80 has its protruding distance 8h matching the depth of a channel 12a of the base 12 or a channel 13a of the top support 13, i.e., in practice, the vertical width of channel flanges 12d or 13d of the base's channel 12a or the top support's channel 13a. Here, the vertical support 14 has the length of its EMC gasket 7; 7a slightly exceeding that of the channel flanges 14d and channel base 14c of the vertical support 14. Hence, the gasket 7; 7a extends from a top edge (outer edge) 14f of the vertical support's 14 channel flange 14d to about a midpoint of the length (protruding distance) 80h of the end face adapter 80.

[0095] The vertical support 14 is mounted on a channel beam 120 of the base 12 by means of said adapter 8 in such a way that the end face adapter 80 has a bearing surface 80a of its end face rested against a channel base 12c of the base's channel 12a or against a channel base 13c of the top support's 13 channel 13a. Hence, the gasket 7; 7a, which is co-directional with a channel flange 14d of the vertical support 14, extends to a gasket 7 extending along a flange 12d or 13d of the base 12 or the top support 13 and following a top edge of the flange. Thus, the gasket 7; 7a has its length designed to be such that it extends all the way of a horizontal gasket 7 extending along a channel flange 12d or 13d of the base's 12 or top support's 13 channel beam 120 or 130.

[0096] Provided that the vertical support 14 has top and bottom ends of its channel beam 140 fitted with an end face support 80, 80, there will be a capability of resting a lower end face adapter 80 of the channel beam 140 against a channel base 12c of the base's 12 base segment 12a and of resting an upper top adapter 80 against a channel 13c of the top support's 13 channel 13a. Thereby, the vertical support 14 has its gasket 7; 7a, which is co-directional with the channel flange 14d, extending all the way to a gasket 7 extending along a flange 12d the base 12 as well as along a channel flange 13d of the top support 13 and following a top edge of the flange 12d and 13d. This way is provided a continuous sealing strip 70 from base segments of the base 12 along a vertical support 14 and further to a top support 13.

[0097] FIG. 6 displays an arrangement used for leveling the base 12. There, underneath a bottom of the mounting frame's base 12 is installed an auxiliary mounting frame 9 such as a rigid metal foil. This is followed by adjusting orientation of the mounting frame's base with respect to the ground or the foundation of a building with screws bearing against the auxiliary mounting frame as well as with a spring retained between the screws.

[0098] In FIGS. 7A and 7B there is respectively displayed two wall elements 31; 31 and 31; 31 for the wall 3 (FIG. 7A) as well as a wall element 31 and a door 5 (FIG. 7B), mounted on a pair of vertical supports 14; 14 and 14; 14 present in a corner formed by segments 121 and 122 of the base 12.

[0099] Hence, the vertical supports 14; 14 and 14; 14 made up of channel beams 140 have mouths thereof opening at an angle of 90 degrees away from each other co-directionally with a channel base 12c, 12c of the base segments 121 and 122 of the base 12 likewise made up of channel beams. This structure, composed of interconnected pairs of vertical supports 14; 14 and 14; 14 and base segments 121, 122 of the base 12, is similar to what has been displayed earlier in FIGS. 1A-1B, 3B and 4B, 4C. Thus, each vertical support of the pair of vertical supports 14; 14 and 14; 14 consists of interconnected channel beams 140, 140 whose construction is similar to what has been described earlier for example in reference to FIGS. 1A and 1B. Likewise, each of both base segments 121 as well as 122 of the base consists of channel beams 120 whose construction is similar to what has been described earlier for example in reference to FIGS. 1A and 1B.

[0100] In FIG. 7A, each wall element 31; 31 and 31; 31 is coupled to the mounting frame 1, which includes not only the aforesaid pair of vertical supports 14; 14 and 14; 14 present at an angle or corner formed by the base segments 121, 122 but also a vertical support 14, which is coupled to an end face of each base segment 121 and 122 and which has its mouth 14b turned perpendicularly towards a vertical support present at the other end of the base segment. In the exemplary FIG. 7A is only shown, seen in a direction from the pair of vertical supports 14; 14 and 14; 14, a third vertical support 14; 14 coupled to one end face 121a of the base segment 121. The vertical support 14; 14 consists of a channel beam 140 whose construction is similar to what has been described earlier for example in reference to FIGS. 1A and 1B. The vertical support 14 has its mouth 14b turned directly towards the vertical support 14; 14 present at an opposite end of the base's 12 segment 121.

[0101] In addition, the mounting frame 1 comprises a horizontal top support, not shown, which connects to top ends of the vertical supports 14; 14 and 14; 14 via an end face adapter (not shown in the figures) present at the vertical supports' top end.

[0102] Each channel beam 120; 120 and 120; 120 making up the base segments 121 and 122 for the base 12 is fitted with a radio-frequency interference suppressing gasekt 7, preferably an EMC gasket. The gasket 7 extends co-directionally (in horizontal direction) with a channel base of the relevant channel beam 120 and 120 along the channel beam 120 and 120 from end to end. One of the channel flanges (12d, 14d) of a channel (12a, 14a) in a channel beam 140; 140, 140 and 140 making up each vertical support 14; 14, 14 and 14 is also fitted with a radio-frequency interference suppressing gasket 7 such as an EMC gasket. The gasket 7 extends co-directionally with a channel base 12c, 14c of each vertical support 140; 140, 140 and 140, i.e. in vertical direction, extending to end face adapters (not shown in the figure) present at bottom and top ends of the channel beam 140; 140, 140 and 140 making up each vertical support 14; 14, 14 and 14 as illustrated in FIG. 5.

[0103] The vertical supports 14; 14, 14 and 14 are mounted on the channel beams 120; 120 and 120; 120 of base segments of the base 12 by means of end face adapters 80 included in bottom ends of the vertical supports 14; 14, 14 and 14. In addition, each vertical support 14; 14, 14 and 14 is coupled to horizontal top supports, not shown in FIG. 7A, by means of an end face adapter (not shown in the figures) included in a top end of each vertical support. The vertical supports 14; 14, 14 and 14 are also coupled, as depicted in FIG. 5, i.e. by means of an end face adapter 80, to the channel beams 120; 120 and 120; 120 the base's 12 base segments and to said top supports. Thus, the gasket 7, which is co-directional with a channel flange 14d of each vertical support 14; 14, 14 and 14, extends all the way to a gasket 7 which extends along a flange 12d or 13d of the base 12 or the top support 13, following a top edge of the flange 12d or 13d. The gasket 7; 7a is designed in such a way in terms of its length that it extends all the way to an elongated gasket 7 extending along a channel beam 120 of the base's base segment or a channel beam 130 of the top support 13.

[0104] Accordingly, the gasket 7, which is co-directional with a channel flange 14d of each vertical support 14; 14, 14 and 14, extends all the way to a seal which extends along a flange 12d of the base's 12 base segment 121 or 122, as well as along a channel flange 13d of the top support 13, following a top edge of the channel flange. Thereby is provided a continuous sealing strip, which extends from each base segment 121, 122 of the base to each vertical support 14; 14, 14 and 14 mounted on these base segments, and further to the top support 13.

[0105] Each wall element 31; 31 and 31; 31 has its bottom end now fitted in a channel 12c of the base segment 121 or 122 included in the mounting frame's 1 base 12. On the other hand, each wall element 31; 31 and 31; 31 has both of its end faces, and side faces adjoining these end faces, fitted in channels 14a of the mounting frame's vertical supports 14; 14, 14 and 14. Each wall element 31; 31 and 31; 31 has its top end face fitted in top supports (not shown in the figures) following the base segments 121, 122. Thereby, the radio-frequency interference suppressing seals 7 make up a continuous sealing strip, which extends from each base segment 121, 122 of the base to each vertical support 14; 14, 14 and 14 and further to the top support 13. This sealing strip is also supported on a bottom end of each wall element 31, on a side face adjoining each vertical side, and on a top end of the wall element, thereby making up a continuous sealing strip encircling an outer edge of the wall element's front side.

[0106] FIG. 7B illustrates part of a mounting frame 1 of the invention provided with a door 5. The mounting frame 1 includes first of all two base segments 121, 122, which are coupled to each other at an angle of 90 degrees and thereby is obtained a corner of the base 12. The constructions of the base's 12 base segments 121, 122, making up a corner of the base, and seals 7 attached thereto, are similar to those depicted earlier in FIG. 4C.

[0107] In a channel 12a of these two base segments 121, 122 of the base 12 is installed a pair of vertical supports 14; 14 and 14; 14, said vertical supports having mouths 14b, 14b and 14b; 14b thereof opening at an angle of 90 degrees relative to each other as presented in FIG. 3A. A seamless sealing strip encircles from each base segment 121, 122 to the vertical supports 14; 14 and 14; 14 as illustrated in FIGS. 3A-3B and 4A-4B. The electrically conductive EMC gasket 7, such as an aluminum strip, extends along the base segment 121, 122 of the base 12 co-directionally with a channel base 12c. When the base segment 121, 122 comes into contact with the vertical supports 14; 14 and 14; 14 (cf. FIG. 1A), the result will be a continuous sealing strip extending from the base segment 121, 122 of the base 12 to each vertical support 14.

[0108] In addition, the base 12 is provided with two vertical supports 14 and 14, which are installed in a channel 12a of a single base segment 121 of the base 12, and whose mouths 14b, 14b are opening at an angle of 180 degrees relative to each other (cf. FIG. 4B). Along one flange of the base's base segment 121 extends a seal, preferably an EMC gasket, which extends co-directionally with its channel base 12c and which, during installation, comes into contact with the EMC gasket of the vertical supports 14, 14 (cf. FIG. 1A). Thereby is obtained a continuous sealing strip encircling from the channel 12a of the base segment 121 of the base 12 to each channel 14b of the vertical support 14, 14.

[0109] This pair of vertical supports 14, 14, installed in the channel 12a of a single base segment 121, can be used for example as an intermediate support for mounting a door 5 as follows:

[0110] A door frame 51 has its bottom piece 51a fitted in a channel 12a present in a base segment 121 of the mounting frame's 1 base 12. The door fame 51 has its first side piece 51b fitted in one of the vertical supports 14; 14 of a pair of vertical supports. The door frame 51 has its second side piece fitted, on the other hand, in the other of the vertical supports 14 installed in the channel 12a of the base's same base segment 121. Hence, the radio-frequency interference suppressing gasket 7 is able to support itself respectively on the bottom piece of the door frame 51 and on each side piece 51b, 51b of the door frame 51. The mounting frame 1 further includes a horizontal door frame support 15 which is coupled to the two vertical supports.

[0111] A head piece 51c of the door frame can be installed on said door frame support: the horizontal door frame support 15 is made up of a channel beam 150, having its channel 15a consisting of a channel base 15c whose both longitudinal sides are provided with channel flanges 15b directed away from said channel base 15c, each additionally extending in a direction which is transverse to that of said channel base 15c. The door frame support 15 has one of its channel flanges 15b; 15b, 15b fitted with a radio-frequency interference suppressing EMC gasket, which extends co-directionally with the channel beam's 150 channel base 15c. Therefore, the door frame support 15 has a basic structure similar to those of the vertical support 14 as well as the segment of the base 12, both of which are also made up of channel beams 140, 120.

[0112] The door frame support 15 connects to a midsection or top end of the vertical supports 14. Its first end connects to one of the vertical supports 14; 14 of a pair of vertical supports and its second end connects in turn to the other of the vertical supports 14 installed in the channel 12a of the base's same base segment 121.

[0113] The door frame has its head piece 51c fitted in a channel (15c) of the mounting frame's 1 door frame support 15 in such a way that the radio-frequency interference suppressing gasket 7 supports itself also on the door frame's head piece.

[0114] FIGS. 8A-8D display various RFID-carrels, which have been constructed with a base and pairs of vertical supports providing an insulation of the invention.

[0115] First of all, these figures display a reading carrel 100 for RFID tags, which is located in a transportable container (FIG. 8A) and accompanied by a storage space for RFID tags and two doors 5 into an interior of the reading carrel 100. The reading carrel is provided with reading means 6 for RFID tags, comprising an antenna as well as a data processing system by way of which there is provided a capability of reading RFID tags to be retrieved from the storage. The storage is located outside of the reading carrel 100 and, thus, no error signals should be allowed therefrom into the reading carrel. Each door 5 to the reading carrel and all wall elements 31; 31, 31, 31, 31 and ceiling of the wall 3 are arranged in a previously described support frame consisting of channel beams and comprising a base 12, vertical supports 14, top supports 13, and door frame supports 14. The channel beams, included in the mounting frame 1 (=support frame), in a base, in vertical supports, in top supports, and in door frame supports, have the channel flange thereof, which is closer to the reading carrel interior, always provided with an encircling continuous sealing strip which has been made of an EMC gasket. The mounting frame 1 and the wall elements fitted thereto have already been installed on the container floor.

[0116] FIGS. 8B and 8C display a reading carrel 100 for RFID tags, which is located adjacent to a storage space or a shop carrying objects equipped with RFID tags. In the shop, the door 5 can be a sliding door.

[0117] In addition, FIG. 8D shows the use of a reading carrel 100 for controlling the passage of persons carrying RFID tags.

[0118] FIG. 9 shows still another reading carrel 100 for RFID tags, which is provided with a glass door. The reading carrel displayed in FIG. 9 has been implemented as described in FIG. 7B and it comprises a base 12, which includes segments 121 and 122 for the base 12, each of which is made up of a channel beam 120 having a top edge of one channel flange thereof traced by a continuous EMC gasket of electrically conductive material. To the segments 121, 122 of the base 12 is connected a plurality of vertical support pairs 14, 14, each consisting of a channel beam 140. To a top end of these pairs of vertical supports is coupled a door frame support 15 as well as a top support 13, both of which are likewise made up of channel beams. Each vertical support 14 of the pair of vertical supports 14, 14, as well as the door frame support 15, are also provided with a continuous EMC gasket as described previously. The EMC gasket encircles in the form of a continuous sealing strip from a first segment 121 of the base to the vertical supports of a vertical support pair 14, 14 located at a corner of the segments 121, 122, as well as to the vertical supports of a second vertical support pair 14, 14 located on the base's segment 121, and further to the door frame support 15 and to the top support. In addition, the EMC gasket encircles in the form of a continuous sealing strip from a second segment 122 of the base 12 to each vertical support 14 of a vertical support pair 14, 14 located at a corner of segments 122 and 123, as well as further to the top support 13. By fitting the glass door, as depicted in FIG. 7B, in the channel of a channel beam 140 of a pair of vertical supports 14, 14, in the channel of a base segment 121, as well as in the channel of a door frame support 15, there is established a structure with the glass door resting by one of its outer edges against the continuous sealing strip. Each wall 31 is installed, as depicted in FIGS. 7A and 7B, in the channel of a segment for the base 12, in the channel of two vertical supports 14 present at opposite ends of the segment, as well as in the channel of a top support 13 connecting these vertical supports. Thereby, each wall is enabled to bear by one of its outer edges against a continuous sealing strip, which extends from a top edge of the base segment's channel flange to a top edge of both vertical supports' channel flanges, and further to a top edge of the top support's channel flange.
