The lateral contour of inner wall 1018 and outer wall 1022 can have any suitable shape.For example, lateral contour can be Circular, triangle, rectangular or other rules or irregular shape.Preferably, lateral contour can have non-circular shape Or irregular shape, so that outer wall 1022 can be fitted between inner wall 1018 by a kind of only orientation.This can force adapter tube 180 Occur specifically to be orientated (for example, so that the expection for providing shank 160 to surface cleaning head 108 is orientated) relative to top 104.Institute In example child, the lateral contour of inner wall 1018 and outer wall 1022 can be described as " egg type ".That is, lateral contour is from one Generally rounding and taper on side to the width of the other side.

The lateral contour of inner wall 1018 and outer wall 1022 has correspondence, alternatively, or in addition, adapter tube 180 and top 104 may include co-operating member, these co-operating members limitation upstream portion 1002 is receivable in the number of the orientation of downstream part 1006 Amount.For example, adapter tube 180 and top 104 can include one or more engagement protrusions and groove jointly.

In the example shown, adapter tube 180 includes protrusion (or key) 1026 in upstream portion 1002, and the protrusion is along outer wall 1022 protrude outward.Protrusion 1026 is configured to be received in Shi Peihe in downstream part 1006 (being inserted into) when upstream portion 1002 The groove (or slit) 1030 being formed in the antelabium 1034 of inner wall 1018.When adapter tube 180 is relative to 104 correct orientation of top When, key 1026 is by aligned slots 1030, to allow upstream portion 1002 to be inserted into downstream part 1006.However, if connecing Pipe 180 is inadequately orientated so that when 1026 misalignment slit 1030 of key relative to top 104, and upstream portion 1002 is inserted in trial Enter into downstream part 1006, then the antelabium 1034 of downstream part 1006 would interfere with key 1026.

In the example shown, hose 124 is electrified, and constitutes from surface cleaning cells 112 and extend to surface cleaning A part of the conduit of head.Therefore, surface cleaning cells 112 may be provided with electric wire or board mounted power (such as one or more electricity Pond), and power via the electrical components of hose 124 and adapter tube 180 into surface cleaning head 108.Therefore, adapter tube 180 can provide Electrified airflow duct for the length conduction along adapter tube 180.As in the illustrative, the upstream portion of adapter tube 180 1002 include electric connector 1038, and the downstream part 1006 on top 104 includes mating electrical connector 1042.Electric connector 1038 and 1042 can be any suitable mating electrical connector, such as male connector (or plug) and female connector (or Socket).In addition, electric connector 1038 and 1042 can connect any amount of electric conductor (such as 1 to 100 electric conductor).As lifted As example explanation, each of connector 1038 and 1042 connects three electric conductors 1046.Upstream portion 1002 and downstream Part 1006 can respectively include any amount of mating electrical connector, and each electric connector can connect different electric conductors.

In some cases, electric connector 1038 and 1042 can be frangible to a certain extent.For example, if electrical connection Device 1038 and 1042 is subjected to certain stress, then can be damaged.In one aspect, the stability that top 104 is provided to adapter tube 180 The stress on electric connector 1038 and 1042 can advantageously be reduced.For example, top 104 and adapter tube 180 and non-electrical connector 1038 Co-operating member (the correspondence lateral contour of such as key 1026 and slit 1030 and/or wall 1018 and 1022) with 1042 can provide Stability (resistance such as mobile relative to the relative rotation between adapter tube 180 and top 104), the stability originally may be by Electric connector 1042 and 1046 is born.

As in Fig. 4 for example, when upstream portion 1002 is received in downstream part 1006, the downstream portion on top 104 Divide 1006 upstream portions 1002 for surrounding adapter tube 180.Preferably, top 104 surrounds adapter tube 180 with enough height, thus to Adapter tube 180 provides support, so that the adapter tube is placed in stand up position.For example, top 104 can surround any part of adapter tube, and And it can be around entire adapter tube.As in the illustrative, top can be around 180 total height of adapter tube (from upstream end thereof 192 to downstream End 188 measure) 10% to 30%, and it is highly preferred that surround 180 total height of adapter tube about 20%.It is same such as to illustrate As bright, upstream end thereof 192 is positioned proximate to the lower end 1062 of surface cleaning cells 112, and is far below surface cleaning The upper end 1066 of unit 112 (when both surface cleaning cells 112 and adapter tube 180 are connected to top 104).It should be appreciated that Upstream end thereof 192 can be pivoted against the outlet end placement of connector 168, or be placed in the outlet end of pivot fitting.

When adapter tube 180 is connected to top 104, adapter tube can form the airtight sealing with airflow channel.Such as illustrate As bright, when adapter tube 180 is connected to top 104, the upstream end thereof 192 of adapter tube 180 can compress the sky around top 104 The sealing element 1070 (such as O-ring) of gas outlet 1074.Sealing element 1070 can prevent air via adapter tube 180 and top 104 it Between interface enter or evolution.

In the example shown, the upstream portion 1002 of adapter tube 180 includes lower section 1078 and upper section 1082.1078 or more lower section Trip end 192 is boundary, and upper section 1082 is in the downstream of lower section 1078.The size and shape of the traversing section of upper section 1082 are set The fixed tight fit at the downstream part 1006 with top 104.Meanwhile lower section 1078 can have substantially lesser traversing section, When starting for lower section 1078 to be inserted into opening 1014, which can provide biggish alignment error limit value.Therefore, user Upstream end thereof 192 can be inserted into top 104.Gap between the wall of 104 facing each other of upstream end thereof 192 and top is advantageous In this insertion.Then, some or all of adapter tube 180 weight can be supported by top 104.Then, user can will take over 180 Rotation to required insertion is orientated, and part or all by insertion upper section 1082 is inserted into complete will take over 180 Operation in portion 104.Relatively narrow lower section 1078 is inserted into top 104 in a step-wise fashion and then is again inserted into wider upper section 1082 To among top, so that user can be easier for upstream portion 1002 to be inserted into top 104.Once lower section 1078 is inserted into In opening 1014, the transverse movement of adapter tube 180 is just by the interaction between lower section 1078 and inner wall 1018 by substantially It constrains at the position of relatively narrow position range, these relatively narrow position ranges will allow upper section 1082 to enter across opening 1014 Downstream part 1006.Because such constraint increases the ratio for the available position for allowing upper section 1082 to enter downstream part 1006, So such constraint is so that user can more rapidly and easily find correct position.

Alternatively, or in addition to relatively narrow lower section 1078, the downstream end 1010 on the top 104 at opening 1014 can be lateral It tilts (or " deflection ").As shown, the front side 1086 of opening 1014 extends above and (further downstream extends) rear side 1090.This allows user to be easier to be positioned at upstream portion 1002 in opening 1014.In use, user can be simple Ground is against the front side 1094 of the mobile upstream portion 1002 in the front side 1086 of opening 1014, so that the alignment opening of upstream portion 1002 1014, then upstream portion 1002 is moved downwardly through to the remainder of opening 1014.By this method, be open 1014 front side 1086 may act as the guiding device of the remainder for upstream portion 1002 to be led into downwards to opening 1014.In view of such Opening forms entire periphery in its uppermost edge, therefore aforesaid way by not tilt (i.e. horizontal) opening laterally than must be grasped Vertical upstream portion 1002 is physically easier to perform.If upstream portion 1002 includes relatively narrow lower section 1078, it is highly preferred that lower section 1078 It can be flushed along front side 1094 with upper section 1082, so that 1002 slide downward of upstream portion be allowed to pass through opening 1014, institute as above It states, without the interference of the overhanging lip by upper section 1082.

Referring now to Figure 11.Alternatively or in addition to this, inclined opening 1014 can help to correct relative to top 104 Adapter tube 180 it is rotary shifted.Top is inserted through in the lower section 1078 for the upstream portion 1002 that at least partly will take over 180 After 104 opening 1014, if adapter tube 180 and opening 1014 are not properly orientated (i.e. rotary shifted) in rotation, on The antelabium 1098 of section 1082 can contact downstream end 1010 at opening 1014.In this case, the downward power of adapter tube 180 F_w, either gravity or user is applied to the power on the contact point between antelabium 1098 and downstream end 1010, can all meet with The reaction force F of inclined downstream end 1010_N.As shown, in addition to horizontal component F_HExcept, reaction force F_NFurther include with Downward power F_wOpposite vertical stress component F_V.Horizontal component F_H180 back rotation of adapter tube is forced to be aligned.For example, if adapter tube 180 rotationally disengage alignment on 1102 in the clockwise direction, then component F_HAdapter tube 180 can be forced to rotate counterclockwise into capable alignment.With The upper section 1082 of this mode, inclined opening 1014 and upstream portion 1002 interacts, and forces adapter tube 180 properly right Standard is so as to insertion opening 1014.

Adapter tube locking mechanism

It is hereafter the description of butt tube locking mechanism, which itself can be used for any surface cleaning apparatus In, or in any combination or sub-portfolio with other any one or more features disclosed herein.

Referring now to Fig. 8.Preferably, once adapter tube 180 is connected to top 104, selectively make adapter tube 180 and top Before 104 separation, adapter tube 180 will all be always maintained at and be connected to top 104.Connection between adapter tube 180 and top 104 can pass through One or more holding elements of locking mechanism maintain, and one or more of holding elements are optionally disengaged.When When locking mechanism engages, upstream portion 1002 will not extract out from downstream part 1006, unless locking mechanism unlocks.Work as adapter tube 180 for when manipulating surface cleaning head 108, this can for example to prevent adapter tube 180 from separating with top 104.

Referring now to Fig. 8 and Figure 19.Figure 19 shows the partial view of the adapter tube 180 including upstream portion 1002, wherein Outer wall 1022 is removed with locking mechanism in exposure (or " adapter tube lock ") 1106.Adapter tube lock 1106 may include locking component, the lock Determine component and releasably engage top 104, selectively will take over 180 latched positions for being fixed on top 104.Such as As illustration, adapter tube lock 1106 includes plunger 1050, which can extend across the opening 1054 of downstream part 1006, To hinder upstream portion 1002 to extract out from downstream part 1006.In addition, plunger 1050 can be it is retractable to be open 1054 Middle extraction, and stop that upstream portion 1002 is hindered to extract out from downstream part 1006.

As in the illustrative, plunger 1050 is located in slit 1110, is used in extended position (showing) and is returned It condenses and is converted between setting.Elastic component such as spring 1114 (Figure 20 a) may act on plunger 1050, so that 1050 direction of plunger Extended position or latched position biasing.At extended position, the end section 1118 of plunger 1050 highlights from slit 1110 Opening 1122 in outer wall 1022.At retraction position, the end section 1118 of plunger 1050 is at least partly drawn back into Into slit 1110.

Preferably, adapter tube lock 1106 is configured to will take over 180 lockings automatically when adapter tube 180 is inserted into top 104 To top 104.For example, the locking component of adapter tube lock 1106 can be certainly when upstream portion 1002 is inserted into downstream part 1006 Dynamic engagement top 104, so that will take over 180 is fixed on top 104.In some cases, locking component can transverse translation (i.e. base Perpendicular to air flow path on this) to be releasably engaged top 104.As in the illustrative, it is inserted into upstream portion 1002 When into downstream part 1006, plunger 1050 can laterally outward translate (or " extension ") opening in downstream part 1006 automatically Mouth 1054, is further acted without user.

In the example shown, the end section 1118 of plunger 1050 includes downside 1126 and opposite upside 1130.Downside 1126 include inclined surface 1134.Originally, in the case where extraction out in upstream portion 1002 from downstream part 1006, plunger 1050 can In extended position.On extended position, the end section 1118 of the inclined surface 1134 including downside 1126 can stretch out across Opening 1122.When upstream portion 1002 to be inserted into downstream part 1006, during insertion, downside 1126 may make Inclined surface 1134 contacts downstream end 1010 at opening 1014.For example, the space between outer wall 1022 and inner wall 1018 can be small The distance of opening 1122 is projected through when end section 1118 is in extended position.Downstream end 1010 can be along inclined surface 1134 Cam action occurs, the biasing for forcing plunger 1050 to overcome spring 1114 bounces back, until the tip 1138 of plunger 1050 is touched To inner wall 1018.When being further inserted into, plunger 1050 can be directed at opening 1054, and horizontal in the case where spring 1114 biases To translating across opening 1054.

When plunger 1050 is in extended position and extends through opening 1054, do not bouncing back at least partly first In the case where plunger 1050, adapter tube 180 will not be extracted from top 104.As in the illustrative, plunger 1050 includes upside 1130.Shown upside 1130 includes 1142 inside of inclined outside faces 1142 and lateral surface with tip 1138 for boundary Do not tilt (or inclination lesser) medial surface 1146.Preferably, in extended position, at least part of medial surface 1146 is prominent Across opening 1054.In this case, if upstream portion 1002 not first retraction plunger 1050 under the premise of attempt from It is extracted out in downstream part 1006, then the upper wall of the accessible opening 1054 of medial surface 1146.Then, the gradient of medial surface 1146 (or lack gradient) can be not enough to for be open 1054 upper wall along the progress cam action of medial surface 1146 with the plunger that bounces back 1050.Therefore, upstream portion 1002 will not extract out from downstream part 1006；Adapter tube lock 1106 is in locking (or " engagement ") position It sets.

Adapter tube lock 1106 may be in response to user's movement and be unlocked by mechanical device, electric device or electromechanical assembly. For example, adapter tube lock 1106 may include operation for unlocking the adapter tube release actuator of adapter tube lock 1106.When adapter tube lock 1106 is in When unlocked position, adapter tube 180 can freely be removed from top 104.

As in the illustrative, top 104 can be terminated far below waist height.For example, top can be 12 inches extremely 14 inches of height.One advantage of shorter upper component is that it promotes adapter tube 180 to be inserted into top 104.In order to connect Pipe 180 avoids user that from must bending over to discharge adapter tube 180 when can be locked in top 104, actuator 1058 can be set In the height that can be activated when user is upright.Actuator such as button 1058 can be by the component such as axis that longitudinally extends 1150 are connected to lock 1106 in a driving manner.Actuator and axis and linkage members can be arranged to a part of adapter tube 180, and And it can be removed together with adapter tube.Therefore, it is incorporated into adapter tube 180 by that will lock with actuator, top 104 can be shorter.

For example, in the embodiment of figure 19, adapter tube lock 1106 includes the conveying member longitudinally extended, and the conveying member is to drive Flowing mode connecting tubes discharge actuator and locking component.For example, conveying member can translate downwards will take over 1106 movement of lock To unlocked position.Moving down conveying member may make locking component to laterally move to disengaging configuration, and will take over lock 1106 and set It is scheduled on unlocked position.

In the example shown, button 1058 is installed on adapter tube 180, and drive shaft 1150 is translated towards plunger 1050.Partially Setting component such as spring 1152 can upwardly bias axis 1150 to retraction position.Axis 1150 can interact with plunger 1050, with Plunger 1050 is moved to retraction position, thus allow be open 1054 upper wall cross at least medial surface 1146 (that is, on the contrary with Entire plunger 1050 is crossed in the inclined engagement of lateral surface 1142).As in the illustrative, plunger 1050 includes facing top Face 1154, and axis 1150 include lower part 1158, which includes the face 1162 of faced downwards.Face 1154 and 1162 can be determined Position is at when downwardly plunger 1050 translates axis 1150 (as shown in Figure 20 b, when button is partially oppressed will lock movement When to unlocked position) it encounters one another.The shape in face 1154 and 1162 can be configured to, as axis 1150 is towards plunger 1050 into one Step translates and provides the cam action for overcoming the biasing of spring 1114 that plunger 1050 is made to bounce back.In the example shown, 1154 He of face Each of 1162 accordingly tilt.As axis 1150 translates downwards, the face 1158 of axis 1150 along plunger 1050 face 1154 carry out cam action, so that plunger 1050 bounces back to retraction position.At retraction position, upstream portion 1002 can be from It is extracted out in downstream part 1006；Adapter tube lock is unlocked (or " being disengaged ").The upper wall of opening 1054 can at least be crossed Prevent the medial surface 1146 of extraction event occurred under lock condition.

Preferably, after button 1058 is released, adapter tube lock 1106 is positively retained at unlock (or " being disengaged ") position.This It allows user using the same hand start button 1058 (unlock adapter tube 180), and then removes and take over from top 104 180.In the example shown, axis 1150 can be biased upwardly (such as by elastic element such as spring 1152).When plunger 1050 When in retraction position, axis 1150 can hinder plunger 1050 to be extended under the biasing of spring 1114, and plunger 1050 can Axis 1150 is hindered to bounce back upwards.As in the illustrative, antelabium 1166 of the plunger 1050 including 1154 lower section of face, and axis 1150 include the antelabium 1170 of 1162 top of face.It is worn in addition, bottom surfaces 1162 can move in the downward translation motion of axis 1150 Cross upper side 1154.When such a situation occurs, plunger 1050 laterally outward translates one section of relatively short distance, thus mobile antelabium 1166 It is contacted with antelabium 1170.Contact between antelabium 1166 and antelabium 1170 prevents axis 1150 to be drawn upwardly out.In addition, lower part 1158 hinder plunger 1050 (as shown in fig. 20 c) in the position of 1050 front of plunger translates further towards extended position. Therefore, lock is maintained at unlocked position.

Preferably, when will take over 180 removals and/or be inserted into top 104, adapter tube lock 1106 can not have to keep In unlocked position.For example, by upstream portion 1002 from when extracting out or be inserted into downstream part 1006 in downstream part 1006, Axis 1150 and plunger 1050 can be disengaged.As in the illustrative, when plunger 1050 is in retraction position, plunger 1050 Inclined lateral surface 1142 and a part of inclined bottom surfaces 1134 can project outwardly through in upstream portion 1002 Opening 1122.This allows to extract out in upstream portion 1002 from downstream part 1006 with the process for the plunger 1050 that further bounces back In, be open 1054 upper wall to inclined lateral surface 1142 carry out cam action.The movement so that plunger 1050 antelabium 1166 Be moved out with the contact of the antelabium 1170 of axis 1150 (as shown in Figure 20 d), thus allow axis 1150 upwards bounce back.In plunger After 1050 cross the downstream end 1010 on top 104, plunger 1050 can extend to extended position under the biasing of spring 1114.

When adapter tube 180 is removed from top 104, adapter tube lock 1106 can also be maintained at unlocked position.For example, when connecing When pipe 180 is removed from top 104, button 1058 can be depressed so that plunger 1050 bounces back, and makes axis 1150 and column Plug 1050 tangles.In this case, will take over 180 and be inserted into top 104 can discharge adapter tube lock from unlocked position.As lifted As example explanation, when plunger 1050 is in retraction position, a part of the inclined bottom surfaces 1134 of plunger 1050 can be to The opening 1122 in upstream portion 1002 is projected through outside.This allows to be inserted into downstream part 1006 in upstream portion 1002 During, opening 1014 at downstream end 1010 to inclined bottom surfaces 1134 carry out cam action so that plunger 1050 into One step retraction.The movement is so that the antelabium 1166 of plunger 1050 is moved out contact (such as Figure 20 d with the antelabium 1170 of axis 1150 It is shown), so that axis 1150 be allowed to bounce back upwards.Once plunger 1050 is directed at the opening 1054 in downstream part 1006, plunger 1050 can laterally outward be moved to extended position under the biasing of spring 1114.

Adapter tube lock release actuator

It is hereafter the description of butt tube lock release actuator, adapter tube lock release actuator itself can be used for any one table In the cleaning device of face, or for any combination or sub-portfolio with any one or more other features disclosed herein In, such as any combination of one or more of first aspect, second aspect, the third aspect, fourth aspect and the 5th aspect Or sub-portfolio.

In some embodiments, the locking mechanism for preventing adapter tube 180 from separating upon connection with top 104 (such as connects 1106) pipe lock can be locked release actuator release by adapter tube.Actuator can be with adapter tube lock mechanical connection, electrical connection or electromechanics even It connects.Preferably, actuator is positioned remote from top 104, in higher than position (Fig. 5) of the top 104 towards shank 160.Example Such as, actuator can be positioned as being on adapter tube 180 or on shank 160 higher than top 104.In some cases, actuator can It is positioned between user's knee height and chest level, and it is highly preferred that high between user's thigh height and waist Between degree.This, which can reduce or exclude user, bends over to start actuator and locks and will take over 180 to discharge adapter tube and separate with top 104 The demand of (for example, to use surface cleaning apparatus 100 under liftoff cleaning mode).

Referring to Fig. 8 and Figure 19, as in the illustrative, button 1058 can be positioned in the length along adapter tube 180 At approximate midpoint.Button 1058 is an example of lock release actuator.This can correspond roughly to the height of user's thigh.Such as Shown in figure, button 1058 can be substantially parallel to the upper end 1066 of surface cleaning cells 112.Button 1058 by axis 1150 with Driving method is connected to plunger 1050.

Lock release actuator can be connected to adapter tube 180, and when adapter tube 180 divides with top 104 and surface cleaning cells 112 (for example, being used for liftoff cleaning mode) is removed from the top Shi Kecong 104 and surface cleaning cells 112.Similarly, in a driving manner The conveying member of the locking component that lock release actuator is connected to adapter tube lock 1106 longitudinally extended be may be mounted into adapter tube 180 On, and when adapter tube 180 separates the top Shi Kecong 104 and surface cleaning cells 112 with top 104 and surface cleaning cells 112 It removes.It may be mounted on adapter tube 180 for example, adapter tube lock 1106 is whole, and when adapter tube 180 and top 104 and surface cleaning list Member 112 separates the top Shi Kecong 104 and surface cleaning cells 112 remove.Surface cleaning apparatus 100 can be advantageouslyed allow for easy in this way In being re-configured to different operation modes.For example, when surface cleaning cells 112 are dismantled (removal) from top 104, adapter tube Lock 1106 can be kept and adapter tube 180 is together to allow the holding of adapter tube 180 to be releasably connected to top 104.

In the example shown, adapter tube lock 1106, axis 1150 and plunger 1050 including button 1058 are all independently of surface Cleaning unit 112 and top 104 are connected to adapter tube 180, and separate in surface cleaning cells 112 and top 104 with adapter tube 180 After keep this connection.

Surface cleaning cells mounting structure

It is hereafter the description to surface cleaning cells mounting structure, which itself can be used to appoint In what surface cleaning apparatus, or for any combination or subgroup with any one or more other features disclosed herein In conjunction, such as any group one or more of in terms of first aspect, second aspect, the third aspect, fourth aspect and the 5th Conjunction or sub-portfolio.

Referring now to Fig. 5.Surface cleaning cells 112 can be removably mounting in top 104 and adapter tube 180 One of or more persons on.Preferably, surface cleaning cells 112 can be mounted on top 104 independently of adapter tube 180, so that In the case where not needing the position of adjustment adapter tube 180 or removing adapter tube 180, enable surface cleaning cells 112 mountable on top It is disassembled on 104 and from top.Thus, for example, when surface cleaning cells 112 are mounted on top 104 or are moved from top Except when, adapter tube 180 can be retained in top 104.

Alternatively, or in addition to this, when surface cleaning cells 112 are mounted on top 104, top 104 can make surface Cleaning unit 112 is firm (for example, when manipulating top 104 to manipulate surface cleaning head 108, can be protected surface cleaning cells 112 Hold the fixation position on top 104).For example, top 104 can inhibit surface cleaning cells 112 along 164 direction of top axis 108 translational motion of surface cleaning head (Fig. 2), and/or can inhibit surface cleaning cells 112 and rotated around top axis 164 It is mobile.

Therefore, surface cleaning cells 112 can be installed on the outside on top 112 by two installation components, wherein installing Component is arranged on two longitudinal directions (for example, along axis 164) position spaced apart, wherein being operable to grasp on top 104 When vertical surface cleaning head 108, at least one of two installation components provide lateral stability.It should be appreciated that settable two Above installation component.

Surface cleaning cells 112 can be slidably received on one or both of installation component.For example, table Face cleaning unit 112 can have one or more grooves wherein to receive one in installation component.Therefore, if installation structure One in part includes a pair of of lateral extension portions (for example, being laterally extended alar part from the outwardly extending left side in opposite side on top It is laterally extended alar part with right side, or be arranged in top there is left side to be laterally extended alar part and right side is laterally extended the outside of alar part Front or behind installation component), then surface cleaning cells 112 can have one or two groove, the position being laterally extended It may be received in the groove.

One in installation component can have enough height, so that when adapter tube 180 is removed and/or surface cleaning When unit 112 is unlocked to remove from top, surface cleaning cells are maintained on fixed position.For example, if installation component packet The lateral extension portions being accepted in groove, groove etc. are included, then in unlocked position, and take over lateral extensions when being removed It is in place that engagement point between the abutment surface of groove, groove etc. can be such that surface cleaning cells 112 stablize in dimension.

Referring to Figure 12 to 15 and 21 to 25, surface cleaning cells 112 and top 104 may include for by surface cleaning cells 112 are connected to one or more installation elements or component on top 104.For example, installation elements may include outwardly projecting installation Component or alar part and correspondence installation groove for receiving these installation components.
