Abstract

STRUCTURE ADAPTED TO BE
SUCCESSIVELY DRAWN AND TELESCOPED

ABSTRACT OF THE DISCLOSURE
A structure comprising a plurality of partition members all of substantially the same size and configuration and each made from sheet material and each providing a pair of spaced opposite partition faces connected at one side and non-connected at the other side, each partition member having the spacing between its opposed faces increasing gradually from its joined edges toward its unconnected edges and joined sides of a pair of adjoining members having a predetermined distance from each other. These partition members are grouped into a telescoped assembly by guiding each of them into the internal space of another when not in use. When in use, the partition members are successively drawn from the telescoped assembly to provide continuous partition faces of a partition between two compartments of a room, sliding door or a window shutter.
The invention thus provides a novel structure which does not occupy a large space when not in use, which can be easily handled, can exhibit an improved sound insulation effect when used as a partition between two compartments of a room, and can be easily manufactured due to a simple construction.

Description

~6~7~72 1 This invention relates to a structure which can be telescoped into a small bulk when not in use and can be drawn or extended when in use to provide a partition between two compartments of a room, a sllding door or a window shutter.
Various types of partitions have been proposed hitherto. Known partitions include the panel type parti-tion in which a plurality of partitioning panels divided into suitable lengths are morably fitted between guides fixed to the ceiling and floor to partition a room in-to two compartments. ~he folding screen type partition is also kno~.~ in which an accordion-like folded partition member is used to partition a room into two compartments.
~hile the panel type partition has a satisfactory sound insulation effect, it is defective in that it occupies a - considerably large space when not in use and it is not so ~ `
easily handled. On the other hand, the folding screen type partition is advantageous in that it does not occupy a large space when not in use and it can be very easily handled. However, -the folding screen type partition is .
defective in that its sour~d insulation effect is little as it is formed of a web of vinyl chloride resin, fabric or the like.
It is therefore a primary object of the present inventior to provide a novel structure which does not occupy a large space when not in use, which can be easily hand'ed, which can exhibit an improvcd so~md insulation cf.^ect when used cLS a partition betwcen two COmpaf'trllentS 0~ a room, arld which be easily manufactured by virtue of sirnple con..truction.

1 Referring now to the drawing, ~ig. 1 shows a first preferred embodiment of the structure according to the present invention when applied to a partition used for partitioning a room into two compartments. The partition is composed of, for example, ten partition ; members 1 to 10 which are movably su ported at the upper end thereof by a guide member 12 fixed to the ceiling 11. ~r The construction of these partition members 1 to 10 will be described in detail with reference to Fig.
2 in which the partition member 2 is only shown.
~eferring to ~ig. 2, the partition member 2 is formed by bending into shape a sheet of metal such as aluminum or ~ ;
steel having an outer face coated in color to bear a ~ pattern resembling the grain pattern of wood. The metal - 15 sheet is bent as by a press -to provide a one-piece ~ structure of substantially U-like cross-sec-tional shape , consisting of a side portion 13 and a pair of partition portions 14 and 15. ~he side portion 13 of shortest length provides a side face, and the two partition portions 14 and 15 extend from the side portion 13 with .
a gradually increasing relative distance therebetween to provide a pair of partition faces. An inwardly protruding stepped section 16 is formed at the boundary between the partition portion 14 and the side portion 13, and an outwardly protruding stepped section 17 is formed adjacent to the open side of the partition portion 14.
The terminal edge of this stepped section 17 is bent outward to eY~tend in substantially parallel relation with the side portion 13. ~1 interconnecting element 1~ is mounted on the top of the outwardly bent terminal .. ~,............................................................... . .

1 edge of the stepped section 17 of the partition portion 14 to clamp this terminal edge at one end thereof while protruding~ diagonally inward at the other end thereof.
A lining 19 of resilient material having a low coe-fficient of friction, such as rubber or ela~tic synthetic resin, is fixed to the terminal edge of the s-tepped section 17 ~ .
of the partition por-tion 14 and ex1ends from the lower ~ -end of the interconnecting element 18 to the lower end of the partition portion 14. This lining 19 has a cross-sectional shape as best sho~n in Fig. 3 so as to cover the terminal edge of the stepped section ]7 of the partition portion 14 at one end thereof while protruding diagonally inward at the other end thereof. The partition -~ portion 15 is similarly provided with such stepped - 15 sections 16 and 17, interconnecting element 18 and ining 19 Another interconnecting element 20 is fixed ;~
at its middle part to an upper end of the side portion 13 of the partition member 2 and has both ends thereof bent diagonally out~ard to be directed toward the associated stepped sections 16. Another lining 21 of .
resilient material ha~Jing a low coefficient of friction, such as rubber or elastic synthe-tic resin, is fiYed at its middle part to the stepped section 16 to extend rom the lo~ler end of the interconnecting element 20 to the lo~7er end of the side portion 13 and has both ends thereof bent di.agonally out~ard to be directed also to~1ard the associated stepped sections 16, as shown in Figs. 2 and 3.

Thereore, a three-point suspension arrangement is provided in which the side portion 13, partition portions 14 and 15 of the partition member 2 are respectively suspended or supported by the sliding pieces 25 received , - in thLe guide rails 23, 22 and 24. A cover 28 covers the guide rails 22, 23 and 24.
The partition member 1 is anchored to a pillar .~ ~ . , .
or wall 29 of a room at its side portion 13. Therefore, the interconnecting element 20 and lining 21 provided on the slde portion 13 of the partition member 2 are unr~ecessary in the case of the partition member 1.
Except for the above difference, the parti-tion member 1 is entirely the same as the partition member 2 in shape and construction. The partition member 10 is detachably -fixed to another ~all of the room at the open side thereof. Therefore, the interconnecting elements 18 and linings 19 provided on the partition member 2 are unnecessary in the case OI the partition member 10.
Except for the above difference, the partition member 10 is entirely the same as the partition member 2 in shape and construction. In the case of the parti-tion member 10, there~ore, a plate (not shown) of the same material as that of the partition plates or of synthetic resin may be mounted on the open side to close the same. r~eans for joining the par-tition members 1 and 10 to the pillars ~0 or walls of the room may be the s.Lmc as those ~ .

The remaining partition members 3 to 9 are entirely the same as the partition member 2 in shape and construction and are similarly movably supported by the three guide rails 22, 23 and 24.
; ~ig. 4 shows a telescopically grouped state of three of these partition members wllen not in use. These three partition members 1, 2 and 3 are drawn from the telescoped state shown in Fig. ~ to a fully drawn state as sho~in in Fig. 5. At first, the user grasps the open~
æide terminal edge of the par-tition mer~ber 3 with his hand to draw the same rightward in ~ig. ~. The inter~
connecting element 20 on the side portion 13 of the partition member 3 engages with the interconnecting elements 18 on the open-side terminal edge of the partition member 2 and with further rightward drawing movement of the partition member 3, the partitlon member 2 is drawn out of the internal space of the partition Inember 1 which is anchored at its side portion 13 to the wall 29 of the room. Thus, the drawing movement is completed when the interconnecting element 20 of the par-tition member 2 engages ~lith the interconnecting elements 18 of the partition member 1. In the fully ~ ;
drawn state, -the lining 21 on the partition member 3 engages ~ith the linings 19 on the partition member 2, and the lining 21 on the partition member 2 engages with the lini~.gs 19 on the partition r.lember 1 to close -the gap between these partition meMbers. Thus, a completely ~0 double-w 11ed structure is provided which improvcs thc ~ !

1 sound insulation effect.
When not in use, the partition members 2 and 3 are telec~.coped into -the internal space of the partition member 1 again. In this case, the user gras,ps the open-side terminal edge of the par-tition member 3 with his hand to move the same letward in Fig. 5. At first, the partition member 3 is received in the internal space of the partition member 2, and then, the partition members and 2 are received in the internal space of the partition member 1. During this operatlon, the inter-connecting elements 18 and linings 19 on the partition members 1 and 2 are pressed inward by the partition portions 1~ and 15 of the partition members 2 and 3.
However, due to the fact that the outwardly protruding stepped sections 17 are provided at the open-side terminal edge of the individual pa,rtition members 9 these inter connecting elements 18 and linings 19 are pressed to be snugly received in the spaces defined by the stepped sections 17. The interconnecting elements 20 and linings 21 on the side portions 13 of the partition members 2 and 3 are also pressed to be snugly received in the spaces defined by the in~lardly protruding stepped sections 16 of the respective partition members. The lining 21 on the outer partition member engages with the stepped sections 16 of the inner partition member to prevent excessive insertion of the inner par-tition mernber into the internal space of the ou1;er partition member.
As above described, it is neccssary to cause inward bending of the interconnecting elemen-ts 1~ and 20 when they are engaged by the partition portions during _ ~ _ ~7~

1 the telescopic grouping of the partition members 1 to ~.
~estraining means (not shown) is preferably provided to restrain outward bending of the interconnecting elements I8. That is, the interconnected elements 18 must be ,5 restrained from bending outward in order that those of the inner partition member can engage with the in-ter-connecting element 20 o~ the outer partition member to , permit drawing of the successive partition members f'rom the telescopically grouped state. The~interconnecting elements 18 and 20 need not possess a high mechanica]
strength when the sliding pieces 25 are arranged to slide along the guide rails 22, 23 and 24 with a low coefficient of friction. The moving directlon of the partition members is limited by the guide rails 22, 23 and 24.
l'herefore, outer face of the inner partition member being telescoped into the outer partition member would not make rubbing engagement with the inner face of the outer partition member. A material such as polytetrafluoro-ethylene resins having a low coefficient of friction is preferably coated on the entire area or selected portions of the inner face of the partition portions of the partition members to reduce the frictional contact.
Figs. 6 and 7 show a second preferred embodiment`
,of the present invention which is actually a modification of the first embod:iment. Referring to Fig. 6, -the interconnecting elements 1~ and 20 are replaced by a flexible linear linking element 31 such as a strap or string of stee] balls which extends between the side plates ]~ of the adjoining partition mcmbers. This linear linklnr,g element ~1 is suf,'f`iciently ]ong so that a-l leas-t ~ ~7147Z ~
.,, , . ;
, 1 a part of the closed side of the partition portions of '~
the inner partition member can be situated within the open side of the outer partition member in the fully drawn state. Referring to Fig. 7, a lining 33 of resilient material having a low coefficient of friction extends from the top to the bottom of each of the terminal edges of the stepped portions 17 of the partition members. -- Each lining 33 covers the terminal edge of the associated stepped section 17 of the parti-tion portion and is formed ~; ''' with an inwardly'protruding hollow projection 32. These projections 32 have a sufficient height so that those -'~
on the outer partition member can engage with the ~ ' ' partition portions on the closed side of the inner '' partition member in the fully drawn state. Further, ~ ' these projections 32 are hollow so that those on the outer partition member can be easily deformed or flattened -~
by being pressed by the partition portions of the inner partition member in the telescoped state. In this second embodiment, therefore, the stepped sections 16 and linings 21 provided ln the first embodiment are unnecessary.
A stopper 34 of resilient material such as rubber or elastic synthetic resin is shown in Fig. 7 and has a sufficient -thickness so that the inner parti-tion member being telescoped may not be forced into the outer parti-tion member more than is required. This stopper 34 actsalso as a cushion for the inner partition member being telescoped into the outer partition member. This stopper 34 is provided on a]l the partition mcMbers except that ~hich is the innerrnost onc in the tc]cscoped assclnbly.

~ig. 8 shows a third preferred embodiment of the -~ ' present invention in which each partition member is ; 10 composed of a pair of independent partition plates 41 ana 42 which are connected together in the area of the side ' portion 13 of the partition members employed in the first and second embodiments. ~;
' Referring to Fig. 8, the partition plates 41 ,~ ~
15 and 42 are bent at one end thereof substantially normal ' to their partition face -to provide a pair of side portions 43 and 44 respectively, and a stepped section 17 (not shown) similar -to that in the first embodiment is formed at the other end of each of the partition plates 41 and 42. The side portions 43 and 44 have such an angle r~lative to the partitioning direction that the relative distance between the partition faces of the partition plates 41 and 42 increases gradually from the position of their side portions 43 and 44. The parti-tion plates 41 and 42 are formed in -the area of their side portions 43 and 44 ~ith holding portions 46 which hold a hanger 45 suspended frorn a guide rail 23 of the kind as .sho~m in Fig. 2.

The hanger 45 is supported by being held between the inner face of the side portions 43, 44 and the holding portions 46. ~hen so required, the hanger 45 may be welded or otherwise fixed to the holding portions 46 or the inner face of the ~.
side plates 43 and 44. A resilient element 48 may be provided to engage at both ends thereof with the inner face of the partition plates 41 and 42 and at one side thereof with the inrier face of the side portions 43 and 44 so as to cushion inwardly directed pressure imparted to the partition plates 41 and 42.
In the third embodiment above described, a pair of independent plates are used to consti-tute a partition member unlike the firs-t and second embodiments.
Thus, the partition member can be more easily manufactured.
Further, the`independent plates can be assembled on the site of construction to facilitate handling of the partition member. This third embodiment is therefore suitable for an application where each partition member has a large surface area. In Fig. 8, only one supporting point is provided at the side face of the partition member as in the first embodiment. ~Iowever, the hanger 45 may rnerely be used as a connecting means for the plates 41 and 42, and holes may be bored in the upper end of the partition portions and side portions to provide four supporting points to be supported by four support or guide rails.

The other side opposite to the ~losed side is open to receive the adjoining partition member therein so that the inner partition member can be ~elescoped into the outer partition member -to provide a t~lescoped assembly of small bulk. The pla-tes constituting the partition members are preferably as thin as possible so that a plurality of these partition members can be telescoped to provide a telescoped assembly having a s~all assembled angle and a small bulk which facilitates transportion and storage.
Figs. 9 to 12 show a fourth embodiment of the present invention in which each partition member is composed of a pair of independent plates as in the third embodiment.
Referring to Figs. 9 and 10, a partition member 2 is composed o~ a pair of partition plates 51 and 52 which are each formed at one end thereof with an inwardly protruding stepped section 53 and at the other end thereof with an outwardly protruding stepped section 54. The plate portion 55 of each stepped section 53 bent in parallel with the parti-tion face is provided at an upper part thereof with a ~ertical]y extending slot 57 for receiving therein onc end of a hanger 56 of substantially inverted-T shape, and a-t a midd]e part thereof rli1,h another vertically extending slot 59 for ~0 recei~ing t~lerein one end of a resilient connecting 0 7~L~7Z

This plate portion 55 is also provided at a lo~er part thereof with another vertically extending slot 62 for receiving therein one end of an interconnecting element 61 of substantially inverted-T shape to which one end of a flexible linear linking element 31 such as a strap or string of steel balls is fixed for inter-connection between the adjoining partition members.
- A cutout 63 is provided at an upper central part of the hanger 56 of substantially inverted-T shape, and a vertically extending slot 64 is provided beneath this cutout 63. The hanger 56 comprises a pair of horizontal wings 65 and 66 which are received loosely in the slots 57 of the partition plates 51 and 52 respectively.
The resilient connecting element 58 is formed of a resilient material such as rubber or elastic synthetic resin. The main body 67 of the connecting element 58 determines the space between the stepped sections 53 of the partition~plates 51 and 52 connected together at this side, and a pair of wings 68 and 69 extend hori~ontally in directions opposite to each other ~rom the main body 67 to be received loosely in the slots 59 of the partition plates 51 and 52 respectively.
These ~ings 68 and 69 are shaped to have a suitable 25 cross-section such as a substantially flat-oval cross-section so as to normally resiliently bias the other or open side of the partition plates 51 and 52 toward each other in a closing dircction.

The end edge of the stepped section 54 of each of the partition pla-tes 51 and 52 is bent at a suitable angle within the stepped section 54 as shown in Fig. 9. ~ ~;
` A cutout 74 is provided at an upper central par-t of the plate portion 73 of the stepped section 54 bent in parallel with the partition face, and a vertically e~tending slot 75 is provided beneath this cutout 74. A lining 76 of resilient material having a low coefficient of friction, such as rubber or elastic syn-thatic resin, is fitted in the stepped section 54 and protrudes at its top end beyond the upper end of the associated partition plate. A rod 77 of metal extends vertically through ;
this lining 7~ to serve as a reinforcement which prevents vertical bending of the associated partition plate.
Another connecting element 78 of resilient material having forked ends is provided to hold the lo~1er part of the plate portions 7~ of the stepped sections 54 of the partition members 51 and 52 between the fork. This resilient connecting element 78 is arranged to have its upper face located beneath the lower end of the partition plates 51 and 52 so as not to obstruct insertion of the adjoining partition members relative to each other.
~s shown in Fig. 10, a hook 79 of substantially ~0 8-like shape engages at its lower -ring with the cutout ~7~72 .
] 63 and slot 6~ of each of the hangers 56. Such a hook '' 79 is also shown engaging with the cutout 74 and slot 75 of each o~ the stepped sections 54. The uppe:r link of each hook 79 is engaged by a suspending link 83 of a sliding piece 82. The hook 79 engaging with the s-tepped section 54 of the partition plate 51 is supported by ;~ the sliding piece 82 recei,ved in a guide rail 22, and the hook 79 engaging with the hanger 56 is suppor-ted by the sliding piece 82 received in another guide rail 23, - 10 while the hook 79 engaging with the stepped section 54 ~, of the partition plate 52 is supported by the sliding piece 82 received in ano-ther guide rail 24. Thus, each partition rnember is movably supported at three points as in the first embodiment.
Referring to ~igs. 10 and 11, a cover member 84 covers the stepped sections 55 of a partition member 1 and serves as a grip to be engaged by the hand during drawing. The partition member 1 is entirely the same in shape and construction as the partition member 2 except the above difference.
Referring to '~ig. 12, a cover member 85 covers the open side of a partition member 10 and serves to join the partition member 10 -to a pillar or wall 29 of a room. ~eans for joining the partition member 10 -to the pillar or wall 29 may be the same as -that conventionally used for a folding screen and will not be specifically described nor illustrated. This part:ition member 10 is also enti-rely the sarne in shape and cons-truction as the partiti,on membcr 2 cxcept the above difference. The remaining partitiGn Members 3 to G~ are also e~ntirely ~, ~6~7~7Z

The width of the main body 67 of the resilient connecting element 58 in a direction normal to -the partition faces determines the space between the stepped sections 53 of the partition plates 51 and 52. Therefore, when this width is suitably selected to establish a substantially parallel relationship between the partition plates 51 and 52 of each partition member in the fully dra~ state, the 20 partition faces of the partition thus completed are :~
substantially flat except the stepped sections 5~ and will not impair the beautiful appearance of the partition.
~ Ihen telescoped together, the partition members 2 to 10 ~re received in the interval space of the partition member 1. The outward expansion of the partition member 1 in this telescoped state is resi.liently absorbcd by the wings 6~ and 69 of the resilient connecting element 5~.

In the present embodiment, the string of steel balls as the linking element 31 is used to connect one partition member to the adjoining one and extends between the interconnecting elements 61 with a length corresponding to the maximurn drawn distance each partition member.
This string of steel balls can be easily fixed to the associated interconnecting element 61 by fitting the same in the cutout 70 at the portion intermediate the balls. ;~
~igs. 13 to 16 show a fifth embodiment of the present invention which is actually a modification of the fourth embodiment. In this embodiment 3 a resilient restraining element 101 is additionally provided in the fourth embodiment so as to restrain outward expansion of the partition plates 51 and 52 in the area of the stepped sections 54 in the fully drawn state.
Referring to Fig. 13, a pair of vertically extending slots 102 are provided in the respective plate portions 55 of the stepped sections 53 of the parti-tion plates 51 and 52 for receiving therein the resilient restraining element lOlo Referring to Fig. 14, the resilient restraining element 101 comprises a main body 103 which determines the space between the stepped sections 53 of the partition plates 51 and 52 connected together at this side. A pair of wings 104 and 105 exte-nd hori~ontally in d:irections opposite to each o-ther fror.~ this main body 103 to be recelved loosely in the - 19 ~

1 slots 102 of the partition plates 51 and 52 respectively.
~ach of these wings 104 and 105 comprises a thin-thickness portion 106 formed adjacen-t to the main body 103 and an engaging portion 107 of substantially flat-~val shape 5 formed adjacent to the thin-thickness por-tion 106 for ~ ;
engagement with the associated stepped section 54. The length between the ends of the engaging portlons 107 is selected to be greater than the distance between the - p~rtition plates 51 and 52. This resilien-t restraining element 101 is a one-piece structure of a resilient material such as rubber, polypropyrene, Vinylon or like elastic synthetic resin.
As shown in ~igs. 1~ and 15, the resilient restraining element 101 extends between the partition plates 51 and 52 while being bent in a pair of openings 108 provided in the portion plates 51 and 52 in the vicinity of the slots 102 OI -the plate por-tions 55 of ;;
their stepped sections 53. There-fore, the engaging ;-portions 107 of the resilient restraining element 101 20 mounted in, for example, the partition member 2 engage at their outer face resiliently wi-th the inner face of -the partition plates 51 and 52 of the partition member 1.
The resilient biasing force imparted by the engaging portions 107 of the resilient restraining element 101 25 is selected to be less than the inward biasing force of the resilient connecting element 5~. The engaging portions 107 engaging with the par-tition plates 51 and 52 are preferably trcated ak their outer face with a suitable rnaterial providing a low coefflcient of friction.

1 stepped sections 54 is bent in parallel with the partition face as shown by 109 in Fig. 13, and the associated engaging portion 107 of the resilient res-train-ing element 101 engages with -this bent portion 109.
When, for example, -the partition member 2 is telescoped into the internal space of the partition member 1, the resilient restraining element 101 in the inner partition member 2 is bent at its thin-thickness portions 106 by the parti-tion plates 51 and 52 of the outer partition member 1. ~he resilient restraining element 101 in the inner partition member 2 engages at its engaging portions 107 with the inner face of the partition plates 51 and 52 of the outer partition member 1 through the openings 108 as seen in Figs. 13 and 15.
In this case the par-tition plates 51 and 52 of the outer partition member 1 would not be urged away from each other, since the outward biasing force imparted by the engaging portions 107 of the resilient restraining element 101 to the inner face of the partition plates 51 and 52 of the outer partition member 1 is less than the inward biasing force imparted by the wings 68 and 69 of the resilient connecting element 58.
~Ihen the partition member 1 is moved leftward - from the position sho~n in Figs. 1~ and 15, the diagonally outward pressure having been imparted by the thin-thickness portions 106 of the resilient restraining member 101 and the vertical pressure having been imparted by the engaging portions 107 of the resilient restraining mcmber 101 in Fig. 15 are replaced by the pressure which :is dirccted ~0 diagonally rear~lard relative to the moving direction.

- ~7~'72 The win~s 10~ and 105 of the resilient restraining member 101 in the partition member 2 are permitted to extend into the stepped sections 54 of the partition member 1 when the bent portion 109 of the stepped sections 54 of the partition member 1 register with the openings 108 of the partition member 2. With further leftward movement ;
of the partition member 1 in Fig. 15, the engaging portions 107 of the resilient restraining element 101 engage finally with the inner face of the stepped sections 54 of the partition member 1 as shown in Fig. 16. The fully extended length of the wings 104 and 105 of the resilient restraining element 101 is selected so as not to urge the stepped sec-tions 54 away f~om each other.
Therefore, no outward pressure is imparted to the stepped sections 54 of the partition member 1 in the fully drawn state, although the stepped sections 54 are engaged by the resilient restrainin~ element 101 of the partltion member 2.
In each individual partition member fully drawn to constitute the partition, the wings 68 and 69 of the resilient connecting element 58 ac-t to bias the stepped sections 5~ toward each other. Thus, the stepped sections 54 of, for example, the partition member 1 are brought into intimate contact with the partition plates 51 and 52 of the par-tition member 2, and the partition members provide a completely double-walled struc-ture which iMproves the sound insulation effect. The dimensions oY the main bodies 103 and 67 of the rcstrain-in~r elcrncnt 101 and connectin~r elernent 58 respective]y deterrni.ne the space bet~een thc stepped sections 53 of thc~

1 partition member. Therefore, these dimensions are preferably selected to establish a substantially parallel relationship between the partition faces provided by -the partition plates 51 and 52 of the individual partition members in the fully drawn state, so that -the overall partition faces can be rendered substantially flat, except the protruding stepped sections 54, without imparting the beautiful appearance of the partition.
Figs. 17 to 20 show one form of holding means used for holding the lower end of partition members in a six-th preferred embodiment of the present invention.
In this embodiment, four partition members 121, 122, 123 and 124 as sho~m in Fig. 17 constitute a partition partitioning a room in-to two compar-tments 9 and the outermost partition member 121 is initially drawn to complete the partition.
A holder 125 extends on a floor 126 in parallel with an upper guide member 120 This holder 125 comprises a base 127 fixed to the floor 126 and having a width larger than the thickness of the partition members 121 to 12~, a pair of upper covers 128 fixed at one end thereof to the base 127 and adapted to be releasably brought into abutment with each other at the other end thereof on the longitudinal centerline of the base 127, and a pair of tapes 129 extending subs-tantially bodily along the lower face of the respec-tive upper covers 12~.
Teeth 130 of a slide fastener are rnounted on the other end of each of the tapes 129 to be releasab1y brought into meshing eng,lgement by a sliding elemen-t 131 of the slide Iastener. ~lhen the teeth 130 are brought into ~leshing , - 23 -~7~

1 engagement by the sliding element 131, the upper covers 128 are brough-t into abutmcnt with each other to be substantially flattened on the base 1270 A pair of pliable restraining strips 132 are interposed between the 5 base 127 and the upper covers 128 so as to restrain the amount of parting movement of the upper covers 128 which are forced away -from each other with the movement of the partition members 121 to 124. The restraining strips 132 are ~olded in a manner as shown in ~ig. 20 when the tee-th - -130 of the slide fastener are brought into meshing engagement. The sliding element 131 is mounted on one end of a carrier 133 which is fixed at the other end thereof to a cover member 84 for the leadi,ng partition ~ember 121. A longitudinal central groove 134 is provided on the base 127 to receive the upper covers 128 thereir when the upper covers 128 are flattened wi-th the movement of the sliding element 131 carried by the carrier 133.
As the leading partition member ]21 is drawn to constitute -the partition between the two compartmen-ts of the room, the sliding element 131 releases the meshing engagement between the teeth 130 as shown in ~ig. 18.
The tapes 129 and upper covers 128 are forced upward by the cover member 8~ to hold therebetween -the lower partition face por-tions of the partition member 121 thereby preventing rolling of the lower par-t of the partition member 121. The parti-tion member,s 122, 123 and ]24 successively drawn ~ith further drawing movement of the partition membcr 121 can also be held a-t their lo~Jer part by -the holder 125 a~ainst ro]ling. Thus, all the partition mcmbers 121 to 12~ are preventcd -f`rom - 21~ -~1~7~7;~

1 rolling in the course of drawing movement to complete the partition.
The partition members ]21 to 12~ constituting the partition are moved rightward in Fig. 17 to be grouped into the telescoped assembly. With rightward movement of the partition member 121, the sliding element 1~1 brings the teeth 130 into meshing engagement again, and the upper covers 128 are substantially -flattened as '~
shown in ~ig. 20. Therefore, when the partition members 121 to 12~ are grouped into the telescoped assembly, the holder 125 is substantially bodily flattened to leave a slight thickness on the floor 126 as seen in Fig. 20.
The transverse end ed~es of the holder 125 may be suitably tapered as illustrated to prevent stumbling or other trouble. The holder 125 may be def,achably mo~mted on the floor 126, and -the sliding-element carrier 133 may be detachably mou-nted on the cover member 84 of the leadlng partition rnember 121 so as to permit removal of the entire holder 125 when the partition members 121 to 124 are grouped i,nto the telescoped assembly.
, , Although the holder in the,si~th ernbodiment is ~ illustrated to include a slide fastener to releasably - hold the lower part of the partition members, those skilled in the are will readily understand that the slide fastener may be réplaced by a nylon tape fastener or a so-called vinyl fastener comprising a male elernent adapted to be fitted in a continuous groove.
The embodiments above dcscribed have referred to an anplication of the struct;ure according to the ~0 prescnt invention to a partition uscd for part:itioning 25 - ' - ~7~

1 a room in-to two compartments. It is apparent that the structure according to the present invention is applicable to a sliding entrance door of a house or room and also to a sliding shutter mounted outside of a door or window to protect against wind or rain, due to the fact tha-t the partition members of double-walled structure exhibit the open-air shutting effect as well as the sound ~;
insulation effect. When the structure according to the present invention is used as such a sliding door or - 10 slidin~ shutter, the drawing ends of the partition members are fixed to guide members or the partition members are held as shown in Figs. 17 to 20 and are reinforced in a direction normal to the partition ~aces so as to withstand the wind or like pressure in the fully drawn state.
