Description

OFFICE POD

FIELD

The present disclosure generally relates to office pods or similar.

BACKGROUND

This section illustrates useful background information without admission of any technique described herein representative of the state of the art.

Office pods, such as soundproof meeting, working or phone booths, are increasingly used in modern furnishing of workplaces as well as public spaces. Such pods are often used for working, meetings, telephone calls and video conferencing.

A conventional office pod comprises opposite wall modules connected to each other by a floor module at the bottom and a ceiling module at the top. These modules form a rigid chassis to which window and/or door frames are attached at sides. The wall modules comprise alternating sound stopping and sound absorbing layers, and an exterior cover (skin layer) at an outermost layer.

In recent times, these kinds of office pods are increasingly more expensive to manufacture.

SUMMARY

It is an object of certain embodiments of the present disclosure to provide a novel

N 20 and inventive office pod of new design.

QA

N According to a first example aspect of the invention there is provided an office pod - enclosing a soundproof workspace inside of the pod, comprising:

N a front load-bearing frame;

E a rear load-bearing frame; and

A 25 a skin layer attached in between the front and rear load-bearing frames so as to

O

O provide the front and rear load-bearing frames with cross-dimensional rigidity.

QA

N A soundproof workspace in this context means that the office pod that encloses a soundproof workspace is purposely configured to prevent sound from propagating to the outside of the office pod, especially at the human speech frequency region.

In preferable embodiments, the soundproofing is at a level at which spoken words inside the office pod can no longer be recognized on the outside of the pod, i.e. said soundproofing renders the speech inside the pod unintelligible on the outside of the pod.

Cross-dimensional in this context means dimensions that are not in the plane nor in parallel with the plane of the load-bearing frame(s) in question. Further, providing cross-dimensional rigidity (or support) is this context means providing (adequate) lateral bracing for the front and rear load-bearing frames. Accordingly, the skin layer providing cross-dimensional rigidity maintains the rectangular shape of the volume between the frames (i.e. provides the effect that the shape of the volume between the frames does not change).

In this context, a "load bearing" frame refers to a frame structure which provides point(s) of attachment and structural support for the other parts of the pod. That is, a 'load bearing" frame is a part which takes structural force load from other above- floor parts of the pod and transfers it to the ground on which the pod stands.

In certain embodiments, the skin layer is in between the load-bearing frames substantially (generally) in the form of a planar, uniform (non-perforated) surface.

The planarity and uniformity of the skin layer contribute to a desired acoustic — behaviour. Here, the desired acoustic behaviour means a drumhead-like vibrating behaviour of the skin layer (as a metaphor). That is, in certain embodiments, the planarity of the skin layer, particularly outside its peripheral regions, enables

N advantageously minimizing its natural freguency, whereby any non-planar forms,

S especially angular ones such as corrugations, would detrimentally increase the = 25 natural frequency of the skin layer.

N It is to be understood that any holes for means of fixing such as screws, bolts and

E: the like are not to be construed as deviations from uniformity of (i.e. are not to be 2 understood as perforations in) the skin layer, as such holes do not remain open for = sound to freely pass through in the assembled pod comprising the skin layer.

N 30 In certain embodiments, the skin layer is (generally) in the form of a plane (i.e., without e.g. corrugations). This means in certain embodiments that elsewhere than in peripheral regions the skin layer is planar (in peripheral regions the skin layer may have non-planar shapes for stiffening and/or for attachment). In certain embodiments, of the total area of the skin layer, at least 80%, more preferably at least 90% is in the form of a plane (i.e. without corrugations or other angular forms), with the non-planar forms, if any, residing at the peripheral regions of the skin layer.

In certain embodiments, the skin layer in between the load-bearing frames is formed of two or more generally planar sub-pieces, especially 2, 3, or 4 sub-pieces, positioned adjacent to each other.

Each of the sub-pieces are generally in the form of a planar, uniform surface. The planarity and uniformity of the sub-pieces of the skin layer contribute to said desired acoustic behaviour. The above-mentioned planarity requirements apply also in such case(s).

In certain embodiments the office pod is provided with stiffening arrangement(s) at joining point(s) or region(s) at which adjacent sub-pieces are joined together.

Accordingly, similarly as in a one-piece implementation in which the otherwise planar skin layer may be bent or curved at regions of the front and rear load-bearing frames (at which they are attached to said frame(s)), the sub-pieces are also generally planar except that they may be bent or curved at regions at which they are joined together with the frame(s) and/or adjacent sub-piece(s).

Accordingly, in certain embodiments, the office pod comprises a stiffening arrangement at a joining region at which one sub-piece is joined together with an adjacent sub-piece.

N

O In certain embodiments, the stiffening arrangement is arranged by bending the sub- — pieces against each other (and attaching an end portion of one sub-piece to an end 0 25 portion of an adjacent sub-piece).

E In certain embodiments, the office pod comprises the skin layer of sound stopping @ material forming an exterior surface (exterior cover) of the pod. In certain

O embodiments, the skin layer is of sheet metal. In certain embodiments, the skin layer

QA . o is of sheet metal made of steel.

Sound stopping material, sometimes also known as soundproofing material, refers to material which predominantly blocks sound waves from travelling through that material, typically by reflection. Such materials are typically hard and dense.

Examples of such materials are steel and concrete.

In certain embodiments, the office pod comprises a sidewall structure comprising said skin layer followed by a sound absorbing material layer. Accordingly, in certain embodiments, the sidewall structure is a layered structure. In certain embodiments, the sidewall structure comprises or consists of superimposed layers. In certain embodiments, the sound absorbing material layer is superimposed on the skin layer.

In certain embodiments, the sidewall structure is implemented without a further sound stopping layer. That is, in such cases, the skin layer is the only sound stopping layer in the sidewall (structure).

In certain embodiments, the sidewall structure comprises a sound absorbing element comprising a plurality of sound absorbing material layers. In certain embodiments, the sidewall structure comprises a sound absorbing element comprising an air layer. In certain embodiments, the sidewall structure comprises the sound absorbing element or a sound absorbing material layer spaced at a distance from the skin layer leaving an air layer therebetween. In certain embodiments, the sound absorbing element is formed of or comprises a sound absorbing material layer and an air layer.

In certain embodiments, the air layer is positioned (sandwiched) in between the sound absorbing material layer and the skin layer. In certain embodiments, the sound absorbing element comprises an inner liner layer facing the pod interior. In

N certain embodiments, the inner liner has a higher flow resistivity than the sound

N absorbing material layer. In certain embodiments, the inner liner layer forms a - 25 second sound absorbing material layer (whereas the first-mentioned sound absorbing material layer forms a first sound absorbing material layer). In certain

E: embodiments, the order of different layers in the sidewall structure are as follows: 2 skin layer (outermost layer), air layer, first sound absorbing material layer, and inner = liner layer (innermost layer). In certain other embodiments, the order of different

N 30 layers in the sidewall structure are as follows: skin layer (outermost layer), first sound absorbing material layer, air layer, and inner liner layer (innermost layer). In certain yet other embodiments, the air layer resides in the middle of the first sound absorbing material layer. In certain yet other embodiments, there are a plurality of air layers within the sidewall structure.

In certain embodiments, the layers of the of the sidewall structure are non- 5 overlapping in a direction perpendicular to the layers (i.e. in the direction that is perpendicular to largest-area surfaces of all layers).

Sound absorbing material refers to material which predominantly allows sound waves to propagate through the material, but while doing so absorbs sound waves so that they do not create echo. Such materials are typically light and airy. Examples of such materials are open-cell foams and textile fabrics.

It is to be understood, as a person skilled in the art readily does, that all materials possess to a degree both sound stopping and sound absorbing properties, but that for example in the case of concrete or steel, the sound stopping property vastly predominates the sound absorbing property, whereby such materials are understood to be sound stopping materials. And correspondingly, in the case of, say, glass wool, open cell foam, fibrous felt and textile fabric, the sound absorbing property vastly predominates the sound stopping property, whereby such materials are understood to be sound absorbing materials.

In certain embodiments, a total mass of the sidewall structure is at most half, or preferably at most one third, of a total mass of any of a front wall comprising the front load-bearing frame and a rear wall comprising the rear load-bearing frame.

In certain embodiments, the total thickness of the sidewall structure is less than 200

N

O mm, more preferably less than 100 mm. - In certain embodiments, the sidewall structure is a non-modular structure. “Non- a 25 modular’ in this context means that the skin layer and the sound absorbing element

E form separate layers not forming an integrated whole. 3 In certain embodiments, the office pod comprises the skin layer being less stiff than © .

N any of the load-bearing frames.

O

N

In certain embodiments, the skin layer is directly attached to the front and rear load- bearing frames.

In certain embodiments, the skin layer is indirectly attached to the front and rear load-bearing frames.

In certain embodiments, the office pod comprises a connector (which may be a rigid connector) connecting the front load-bearing frame and the rear load-bearing frame, and the skin layer being attached to the connector. In certain embodiments, the connector is in the form of a bar or beam. In certain embodiments, the connector is hollow. In certain embodiments, the hollow connector is to house wirings and/or electrical components. In certain embodiments, the hollow connector provides a fire enclosure for mains voltage electric components of the pod thereby eliminating a need for a separate fire enclosure for mains voltage electric components. When serving as such a fire enclosure, the hollow connector is made of incombustible material such as of metal, preferably steel, or flame-retardant plastic, preferably SVA plastic.

In certain embodiments, the connector is a non-vertical connector. In certain embodiments, the connector is a horizontal or substantially horizontal connector.

In certain embodiments, the office pod comprises said skin layer at both a left-hand side and a right-hand side of the pod, wherein a chassis with cross-dimensional support is formed of said skin layers and said load-bearing frames.

In certain embodiments, the functional layers concerned with soundproofing in a sidewall of the office pod consist of said skin layer, and said sound absorbing element, said sound absorbing element consisting of said sound absorbing material layer with or without one or more air layers, and an optional inner liner (or interior

N panel) comprising sound absorbing material (superimposed on said sound

N absorbing material layer). 0 25 In certain elements, the rigidity of the pod is enhanced by a ceiling structure attached

I to the front load-bearing frame and to the rear load-bearing frame. In certain * embodiments, the ceiling structure is preferably configured to implement a

E ventilation function. ä In certain embodiments, the rigidity of the pod is further enhanced by a floor structure attached to the front load-bearing frame and to the rear load-bearing frame. In certain embodiments, said rigid connector is integrated into the floor structure.

In certain embodiments, the front load-bearing frame and/or the rear load-bearing frame comprises a door.

In certain embodiments, the front load-bearing frame and/or the rear load-bearing frame surrounds or at least partly surrounds a door or a door frame.

In certain embodiments, the front load-bearing frame constitutes an outermost encircling element of the front wall. In certain embodiments, the rear load-bearing frame constitutes an outermost encircling element of the rear wall.

According to a second example aspect of the invention there is provided a method of assembling the office pod of the first aspect or any of its embodiments, comprising: - assembling a chassis of the office pod by first providing the front and rear load-bearing frames, followed by attaching right-hand side and left-hand side skin layers directly or indirectly to the front and rear load-bearing frames to form a cross-dimensionally rigid chassis, and thereafter - attaching further parts of the office pod to said chassis for forming a finished office pod.

Different non-binding example aspects and embodiments have been illustrated in the foregoing. The embodiments in the foregoing are used merely to explain selected aspects or steps that may be utilized in different implementations. Some embodiments and features may be presented only with reference to certain example aspects. It should be appreciated that corresponding embodiments and features

Embodiments of an office pod in accordance with the present disclosure comprise a front load-bearing frame, a rear load-bearing frame, and a skin layer attached in between the front and rear load-bearing frames, wherein the skin layer provides the

N front and rear load-bearing frames with cross-dimensional rigidity. Accordingly, e.g.,

N 25 — in certain embodiments, the office pod comprises said skin layer at both a left-hand - side and a right-hand side of the pod, wherein a chassis of the pod with cross-

N dimensional rigidity (or support) is formed of said skin layers and said load-bearing

E frames. In certain embodiments, cross-dimensional rigidity of said frames means a 2 structural property of resisting the frames becoming and/or being tilted from an = 30 upright position. In other words, cross-dimensional rigidity of said frames means

N resistance against forces trying to alter the mutual position of said frames once erected, especially in a tilting manner.

Fig. 1A shows an exploded view of selected parts of an office pod 100 in accordance with certain embodiments, and Fig. 1B shows an assembly of a chassis of the office pod 100 with the parts shown in Fig. 1A. The office pod 100 comprises a front load- bearing frame 110, a rear load-bearing frame 120, a left-hand side skin layer 130, and aright-hand side skin layer 140. The left-hand side skin layer 130 is attached in between the front load-bearing frame 110 and the rear load-bearing frame 120 at the left-hand side of the pod 100, and the right-hand side skin layer 140 is attached in between the front load-bearing frame 110 and the rear load-bearing frame 120 at the right-hand side of the pod 100.

Said attaching “in between” the load-bearing frames in this context and further in the following description means that the skin layers reside in between the load-bearing frames but need not reside in between the load-bearing frames in their absolute entirety. For example, edge portions of the skin layer in certain embodiments are overlapping with respect to the respective load-bearing frames e.g. for an attachment purpose. Thus, a skin layer attached in between the front and rear load- bearing frames is to be understood so that the skin layer may, at its peripheral regions, gain attachment from the load-bearing frames in such a manner that the skin layer may, at said peripheral regions, overlap with the frames but is otherwise between the load-bearing frames.

The skin layer(s) 130, 140 provide the front and rear load-bearing frames 110, 120 with cross-dimensional rigidity (lateral bracing).

The left-hand side skin layer 130 comprises an attachment point 131-134 at each

N corner (or corner region) of the layer 130. Similarly, the right-hand side skin layer

S 140 comprises an attachment point 141-144 at each corner (or corner region) of the = 25 layer 140. The skin layers 130, 140 are attached to the front and rear load-bearing 0 frames 110, 120 at the attachment points 131-134 and 141-144 (preferably in an z immovable manner) so as to provide the front and rear load-bearing frames 110,

N 120 with cross-dimensional rigidity. Further, in certain embodiments, the skin layers o 130, 140 in between the frames 110, 120 generally are in the form of a planar, ä 30 uniform surface (forming a sound stopping layer).

Fig. 2A shows an exploded view of selected parts of an office pod 200 in accordance with certain embodiments, and Fig. 2B shows an assembly of a chassis of the office pod 200 with the parts shown in Fig. 2A. The office pod 200 comprises a front load- bearing frame 210, a rear load-bearing frame 220, a left-hand side skin layer 230, and a right-hand side skin layer 240. The left-hand side skin layer 230 is attached in between the front load-bearing frame 210 and the rear load-bearing frame 220 at the left-hand side of the pod 200, and the right-hand side skin layer 240 is attached in between the front load-bearing frame 210 and the rear load-bearing frame 220 at the right-hand side of the pod 200. The skin layer(s) 230, 240 provide the front and rear load-bearing frames 210, 220 with cross-dimensional rigidity (lateral bracing). — Further, in certain embodiments, the skin layers 230, 240 in between the frames 210, 220 generally are in the form of a planar, uniform surface (forming a sound stopping layer).

The left-hand side skin layer 230 comprises an attachment point 231-234 at each corner (or corner region) of the layer 230. Similarly, the right-hand side skin layer 240 comprises an attachment point 241-244 at each corner (or corner region) of the layer 240. In contrast to the embodiments shown in Figs. 1A and 1B, the skin layers 230, 240 are not directly attached to the frames 210, 220, but there are separate connectors 251, 252, 261, 262 connecting the frames 210, 220, and the skin layers 230, 240 are attached to the frames 210, 220 (preferably in an immovable manner) via respective connectors.

In the embodiments shown in Figs. 2A and 2B, the left-hand side skin layer 230 is attached at its top corners (or corner regions) at attachment points 231 and 232 to a first (upper) connector 251 attached in between the frames 210, 220 at the upper

N left-hand side of the pod 200. Similarly, the left-hand side skin layer 230 is attached = 25 — atits lower corners (or corner regions) at attachment points 233 and 234 to a second = (lower) connector 252 attached in between the frames 210, 220 at the lower left- - hand side of the pod 200.

T

N The right-hand side skin layer 240 is attached at its top corners (or corner regions) o at attachment points 241 and 242 to a third (upper) connector 261 attached in

N 30 between the frames 210, 220 at the upper right-hand side of the pod 200. And,

N similarly, the right-hand side skin layer 240 is attached at its lower corners (or corner regions) at attachment points 243 and 244 to a fourth (lower) connector 262 attached in between the frames 210, 220 at the lower right-hand side of the pod 200.

The connectors 251, 252, 261, 262 themselves in certain embodiments are as such substantially non-participating as to functionally providing the front and rear load- bearing frames 210, 220 with cross-dimensional rigidity, but the skin layers 230 and 240 provide the front and rear load-bearing frames 210, 220 with cross-dimensional rigidity (as a combined effect together with the connectors 251, 252, 261, 262 in certain embodiments).

Put more generally, the connectors 251, 252, 261 262 need not provide the front and rear load-bearing frames 210, 220 with cross-dimensional rigidity due to skin layers 230, 240 providing this functionality, though the connectors 251, 252, 261, 262 doing so is not detrimental to the rigidity of the pod chassis. Consequentially, the connectors 251, 252, 261, 262 may be attached to the front and rear load- bearing frames 210, 220 in a simple and economical manner. — Further, the embodiments shown in Fig. 1A-2B present attachment points at corners or corner regions. It should be noted that the present disclosure shall not be limited to solutions having attachment points only at corners (or corner regions) but in embodiments of the present disclosure there are or may be attachment points also in other regions of the respective skin layers (as shown for example in connection with Figs. 10A, 10B, 11A, and 11B in the following description). However, any attachments point in these and further embodiments are preferably located at peripheral regions of the skin layer(s). In certain embodiments, the skin layer(s) are

N attached at their peripheral regions and the remaining (i.e., centre) region is non-

O attached. In certain embodiments, the skin layer(s) do not touch any structure = 25 behind them so that they are able to freely vibrate.

E: accordance with certain embodiments, and Fig. 3B shows an assembly of a chassis 2 plus a ceiling and a floor of the office pod 200 with the parts shown in Fig. 3A. The = embodiments shown in Figs. 3A and 3B otherwise completely correspond to the

N 30 structure and operation of the pod 200 shown and described in the preceding in connection with Figs. 2A and 2B, but Figs. 3A and 3B further show a ceiling structure

270 and a floor structure 280 attached to the front load-bearing frame 210 and to the rear load-bearing frame 220. In certain embodiments, the ceiling structure 270 and the floor structure 280 as such are substantially non-participating as to functionally providing the front and rear load-bearing frames 210, 220 with cross- dimensional rigidity. However, in certain embodiments, the rigidity of the pod 200 is further enhanced by attaching the ceiling structure 270 and the floor structure 280.

Put more generally, the ceiling structure 270 and the floor structure 280 need not provide the front and rear load-bearing frames 210, 220 with cross-dimensional rigidity due to skin layers 230, 240 providing this functionality, though the ceiling structure 270 and the floor structure 280 doing so is not detrimental to the rigidity of the pod chassis. Consequentially, the ceiling structure 270 and the floor structure 280 may be attached to the front and rear load-bearing frames 210, 220 in a simple and economical manner.

In certain embodiments, the ceiling structure 270 is configured to implement a ventilation function. For this purpose, in certain embodiments, the ceiling structure comprises an integrated ventilation system 271.

The embodiments shown in Figs. 4A and 4B otherwise completely correspond to the structure and operation of the pod 200 shown and described in the preceding in connection with Figs. 2A, 2B, 3A and 3B, but Figs. 4A and 4B further show the left-

N hand side skin layer 230 formed of two sub-pieces 230a and 230b. Similarly, the

O right-hand side skin layer 240 is formed of two sub-pieces 240a and 240b. In certain = 25 embodiments, joining points or regions of the sub-pieces contain appropriate 0 stiffening arrangements (so as to provide stiffness to withstand a skin layer-bulging z force caused for example a person in the pod leaning against the wall). In certain 2 embodiments, the joining regions reside at edge regions of the sub pieces, while

O other areas (central areas) of the sub-pieces generally are in the form of a planar,

O 30 uniform surface (forming a sound stopping layer). The joining points or regions in certain embodiments contain or provide attachment loci for fixings with which the sub-pieces 240a, 240b are attached together.

Fig. 5A shows an exploded view of selected parts of an office pod 300 in accordance with certain embodiments, and Fig. 5B shows an assembly of a chassis plus a ceiling and a floor of the office pod 300 with the parts shown in Fig. 5A. The embodiments shown in Figs. 5A and 5B otherwise completely correspond to the structure and operation of the pod 200 shown and described in the preceding in connection with Figs. 2A to 4B, but Figs. 5A and 5B further show the upper connectors (marked by 351 and 361) integrated with the ceiling structure (marked by 370), and the lower connectors (marked by 352 and 362) integrated with the floor structure (marked with 380).

Fig. 6A shows the office pod 200 cut by a virtual horizontal plane A to obtain cross- sectional views of the office pod 200 at a location at which the right-hand side skin layer 240 connects with the front load-bearing frame 210. Fig. 6B shows an example in which a curved end portion of the skin layer 240 fits into a respective vertical groove in the frame 210. Fig. 6C shows an example which otherwise corresponds to the example shown in Fig. 6A except that the frame 210 further comprises a magnet or magnets 215 at a side of the frame 210 to provide an attractive magnetic force between the frame 210 and the skin layer 240. Such magnet(s) 215 provide ease of assembly as the skin layer 240 can be magnetically snapped in place, whereafter any other fixing(s) can be performed with the skin layer 240 already remaining in place. Such magnet(s) 215 provide attaching force between the frame(s) 210 and the skin layer 240 so as to prevent rattling of the skin layer 240 against the frame(s) 210 without a need to use in those areas fixings which are more time-consuming in pod assembly and/or require penetration through the acoustically

The skin layers 1230, 1240 are not directly attached to the frames 1210, 1220, but

N there are connectors 1251, 1352, 1261, 1362 connecting the frames 1210, 1220,

O and the skin layers 1230, 1240 are attached to the frames 1210, 1220 via respective = 25 connectors.

N In certain embodiments, the connectors 1251, 1352, 1261, and 1362 are non-

E Yet further, Figs. 10A and 10B show the left-hand side skin layer 1230 formed of © two sub-pieces 1230a and 1230b. Similarly, the right-hand side skin layer 1240 is

O formed of two sub-pieces 1240a and 1240b.

QA a The skin layer(s) 1230, 1240 formed of a plurality of sub-pieces (here: two sub- pieces) provide the front and rear load-bearing frames 1210, 1220 with cross-

dimensional rigidity (lateral bracing). Further, in certain embodiments, the separate and connected sub-pieces 1230a and 1230b (1240a and 1240b, respectively) of the skin layers 1230, 1240 in between the frames 1210, 1220 generally are in the form of a planar, uniform surface (forming a sound stopping layer) to provide desired acoustic behaviour. By the desired acoustic behaviour is meant a drumhead-like vibrating behaviour of the sidewall (as a metaphor).

Fig. 11A shows a magnification of a certain detail of the office pod 1300.

Accordingly, Fig. 11A shows an optional row of attachments points in between a right-most attachment point 1231 at top-right corner (or corner region) of the left- hand side skin layer 1230 and a left-most attachment point 1232 at top-left corner (or corner region) of the left-hand side skin layer 1230. In certain embodiments, the left-hand side skin layer 1230 is attached to the first connector 1251 via these attachment points. The same equally applies to the right-hand side wall.

The stiffening arrangement (or shape) 1240c in the middle provides the sidewall with anti-bulging support in the event a person is leaning against the sidewall (without deteriorating the desired acoustic behaviour). The same equally applies to the left-hand side wall.

Fig. 12 shows a magnification of yet another detail of the office pod 1300.

Accordingly, Fig. 12 shows the left-hand side skin layer 1230 to be attached to the

N 30 connector 1251 at the right-most attachment point 1231 at top-right corner (or corner region) of the left-hand side skin layer 1230. Fig. 13 further shows the first corner piece 1393 attached to the left-hand side skin layer 1230 at the same attachment point 1231. In certain embodiments, as shown in Fig. 13, the left-hand side skin layer 1230 and an end portion of the first corner piece 1393 are bent so that they overlap each other. Further, in certain embodiments, the bent parts form a pocket for receiving an add-on rail 1235 (schematically illustrated) for providing a system for attaching additional parts or accessories to the pod, such as a shelve, a desktop table or a whiteboard. The same equally applies to the right-hand side wall.

Fig. 14 shows a further detail of the office pod 1300 in accordance with certain embodiments. In these embodiments, the office pod 1300 comprises an optional cross brace 1555 in between the front load-bearing frame 1210 and the rear load- bearing frame 1220. This additional cross brace 1555 is positioned within the wall structure behind the skin layer 1240 (when approaching the interior of the pod 1300 from the outside). The purpose of the cross brace 1555 is to provide the sidewall in question with anti-bulging support in the event a person is leaning against the sidewall from the inside of the office pod. The actual structure of the cross brace 1555 depends on the implementation.

Fig. 15 shows a similar cross brace 1555 in the office pod 100. Fig. 15 further shows the first and second sound absorbing layers 245, 246 behind the right-hand side skin layer 240. Fig. 15 further shows a hollow bar 1666 attached in between the front load-bearing frame 110 and the rear load-bearing frame 120. In certain embodiments, the hollow bar 1666 does not provide cross-dimensional rigidity (however, in other embodiments it may provide cross-dimensional rigidity) but accommodates mains voltage electric components within the pod structure and to

N provide attachment for a work surface (not shown). In certain embodiments, the = 25 hollow bar provides a fire enclosure for mains voltage electric components of the = pod thereby eliminating a need for a separate fire enclosure for mains voltage - electric components. When serving as such a fire enclosure, the hollow bar is made

E of incombustible material such as of metal, preferably steel, or flame-retardant

E plastic, preferably SVA plastic.

Fig. 17 shows positions of attachment points for a single piece skin layer (for example skin layer 240) in accordance with certain embodiments. In order to provide cross-dimensional rigidity, the skin layer 240 in certain embodiments comprises at least three attachment points 24X at peripheral regions of the skin layer. Fig. 17 shows certain alternatives of their positioning.

Fig. 18 shows positions of attachment points for a skin layer formed of a plurality of sub-pieces (here: two sub-pieces 240a and 240b) in accordance with certain embodiments. In embodiments, in which the sub-pieces are joined with each other (left-most drawing), through stiffening arrangements of similar, the skin layer (combination) 240 comprises at least three attachment points 24X at peripheral regions of the skin layer 240. If the sub-pieces 240a, 240b are not joined with each other (so that the sub-pieces 240a and 240b can move in relation to each other) the requirement of at least three attachment points (as shown in the preceding in connection with Fig. 17) apply separately for both sub-pieces (right-most drawing).

In certain embodiment, instead of three attachment points, four or more attachment points are implemented.
