Abstract
Description
- The present invention relates to partition wall fastening units to be utilized for application of partition walls to houses or buildings, when the space therein is partitioned following a variety of requests regarding the layout thereof.
- It is not seldom to build buildings or houses of which each floor is remained completely without partition or with very little partition, because it'is convenient for meeting the specific request of residents or tenants concerning the layout of the space thereof following their'specific objects to use the space thereof. Further, this will readily allow remodeling of the layout, such request is inclined to frequently happen afterwards.
- In the prior art, panel type partition walls are fitted to either ceilings or floors or walls through fitting parts which are bolted with insert beds which are from the beginning embedded in slabs forming structural parts of buildings or houses. This means that the selection of layout is extremely limited, when the panel type partition wall in the prior art is utilized, because such a wall can be fitted only at the place where insert beds have been embedded from the beginning.
- When a remodeling is requested for a layout, it becomes necessary to embed insert beds at different places following the revised layout. This means that the insert beds which were from the beginning embedded will have to be given up. This will usually remain ugly spots on the surface of ceiling, floor and wall, after spending a considerable amount of money. Further, cases may be that some of the specific layout will be difficult to implement in the event that some of the specific place do not allow insert beds to be embedded due to the unexpected existance of some type of obstacles such as stones at the same specific place. In addition, it is to be noted that workmen will be requested to take a hard posture during the period in which they carry out this type of work.
- As an improvement, a method which utilizes air pressure has been proposed. A pair of frames consisting of an upper and a lower frames and containing an airtight bag made of a resilient material therein, is mounted on top of a partition wall. The resilient airtight bag pushes the upper frame against the under surface of a ceiling, when it is inflated with the air blown into the bag. Since this method relies predominantly on the air pressure in the bag, however, it is not necessarily reliable due to the inherently unavoidable deterioration of the resilient material which forms the bag. Further, this type of partition walls has much possibility to cause a variety of unexpected accidents.
- Accordingly, every method available in the prior art is not satisfactory from the viewpoints of the various requirements such as conveniency in application and removal of the partition walls, less expensive cost for application work and flexibility in meeting a variety of rquired layouts.
- According to the present invention, there is provided a partition wall fastening unit for fixing a partition wall between a ceiling and a floor of a building construction, comprising: a first frame; a second frame vertically movable relative to said first frame; a sliding bed slidably disposed on said first frame; a pressing bed connected to said second frame; means operatively connected between said sliding bed and said pressing bed to convert sliding movement of said sliding bed into vertical movement of said pressing bed; and a drive mechanism for slidably moving said sliding bed to vertically move said pressing bed and accordingly said second frame for thereby fixing said partition wall between said ceiling and said floor.

- Figs. 18 and 19 are cross sectional views of modified forms of a partition wall fastening unit of the present invention.
- Referring to Figs. 1 through 4 of the drawings which show a prefered embodiment of a partition wall fastening unit in accordance with the present invention, reference numeral 1 is a lower frame having a U shape cross section defining a cover, and 2 an upper frame having a U shape cross section and accommodated in the lower frame 1. A
sliding bed 3 and apressing bed 4 are disposed between theupper frame 2 and the lower frame 1. Theupper frame 2 is allowed to vertically move up and down, and thesliding bed 3 is allowed to horizontally move. Thepressing bed 4 and thesliding bed 3 are connected each other by a plurality oflinks 5, allowing thesliding bed 3 to push thepressing bed 4 upward, when thesliding bed 3 is horizontally moved to the left along the bottom surface of the lower frame 1. The number of links may be arbitrarily determined in dependence on the magnitude of pressure to be applicable between a ceiling and the partition wall fastening unit. Indicated as 8 is a bracket rigidly fitted on one end of thesliding bed 3 by some proper means such as welding, and with an opening forscrew 9 penetrating the slidingbed 3 from side to side. It is of course possible to integrate thebracket 8 and thesliding bed 3. Indicated as 10 is a bracket arranged at one end of the lower frame 1. Anopening 11 formed in thebracket 10 allows abolt 12 to reach anopening 9 formed in thebracket 8 where thebolt 12 is screwed with thebracket 8. Abolt stopper 13 is located between thebracket 8 and thebracket 10 indicated as 14 is a recess in which the head of thebolt 12 is held. Indicated as 15 is a plurality of spring supporting rods. The upper end of eachspring supporting rod 15 is rigidly fitted to the lower surface of theupper frame 2 by some proper means such as welding, and the lower end of eachspring supporting rod 15 suspends thepressing bed 4. Sincecompression springs 16 are arranged along thespring supporting rod 15 between the lower surface of theupper frame 2 and the upper surface of thepressing bed 4, thepressing bed 4 urges thecompression springs 16 upward for thereby raising theupper frame 2 to fix the partition wall between the ceiling and the floor. Indicated as 17 is a spacer placed between the upper surface of theupper frame 2 and theceiling 19. Indicated as 18 is a hole formed in the side wall of the lower frame 1 for inspection of the inside thereof. - Fig. 5 is a sectional view of the partition wall fastening unit showing a state in which the
pressing bed 4 is raised to cause theupper frame 2 to urge theceiling 19 through thespacer 17. ; - Described below is a process to reach the position shown in Fig. 5 from the position shown in Fig. 2. When the
bolt 12 is rotated clockwise by means of a tool such as a wrench (not shown in the drawings), thebracket 8 as well as thesliding bed 3 is pulled towards thebracket 10. Incidentally, thelinks 5 which are clockwise rotated by the slidingbed 3 push up thepressing bed 4. Since the number of thelinks 5 is more than one, the upper surface of thepressing bed 4 is kept in parallel with the upper surface of the lower frame 1. Even in the case where the lower surface of theceiling 19 is not in parallel with the upper surface of the lower frame 1, the upper surface of theupper frame 2 is kept in parallel with the lower surface of theceiling 19 by assistance of thecompression springs 16. In other words, the difference in distance between the lower surface of theceiling 19 and the upper surface of theupper frame 2 is adjusted by the corresponding difference in deformation of thecompression springs 16. As a result, even in the case where the lower surface of theceiling 19 is not in parallel with the upper surface of the lower frame 1, the upper surface of theupper frame 2 is urged uniformly against the lower surface of theceiling 19. In addition, it is possible to adjust the compression pressure between the lower surface of theceiling 19 and the upper surface of theupper frame 2 by selection of the strength and number of thecompression springs 16. Further, when the slidingbed 3 is fitted at a position where thepressing bed 4 does not urge theupper frame 2, it is possible to float it with a constant pressure applied therei In this case,since it makes a flexible construction,it is capable to absorb any strain such as expansion or contraction due to earthquakes or aging. - Following description discusses the position in which the partition wall fastening unit is put into the practical application.
- Fig. 6 is a vertical sectional view showing a position in which the partition wall fastening unit as well as a sound-proof cover is mounted in a recess defined on top of a partition wall standing on a floor and below a ceiling. Referring to Fig. 6 of the drawings, indicated as 20 is the surface of a floor, and a
partition wall 21 includes afront panel 22 and arear panel 23 holding acore 24 between the two panels. Indicated as 25 is a recess defined on top of thepartition wall 21, and the partition wall fastening unit is placed in therecess 25. Indicated as 26 is a sound-proof cover which is placed on thespacer 17 which is further placed on the upper surface of theupper frame 2. Theother spacer 27 is placed between the lower surface of theceiling 19 and the upper surface of the sound-proof cover 26. It is possible to form thespacer 27 either in one body as shown in Fig. 6 or in a pair of split bodies each of which is placed on either end of the sound-proof cover 26. The another set ofspacers proof cover 26 and the front andrear panels partition wall 21 and thefloor 20. - When the paritition wall is put into application, the
partition wall 21 is mounted with the partition wall fastening unit placed in the recess on top of thewall 21 and with the sound-proof cover 26 disposed between the fastening unit and the ceiling. As described in the above with reference to Figs. 1 and 5, a rotation of thebolt 12 causes the slidingbed 3 to slide whereby thepressing bed 4 is moved upward to raise theupper frame 4 until theupper frame 4 contacts with theceiling 19 and urges the sound-proof cover 26 and thespacer 27 against theceiling 19. The final position is as shown in Fig. 7. - The sound-
proof cover 26 may be substituted by a frame attached with a magnet M, as shown in Fig. 8, arranged on theupper frame 2. - The above mentioned operation is continued until the partition is completed for the entire floor to implement a specific layout in houses or buildings.
- The final unit completing a linear series of partition is a modified one with a recess from which the operation is possible for rotation of the
bolt 12. The recess is closed after the application work is completed for the partition wall fastening units. - The process for removing the
partition wall 21 will be described below. Referring to Fig. 5, an counter clockwise rotation of thebolt 12 causes thebracket 8 and the slidingbed 3 to move away from thebracket 10 against the tension of thecompression spring 16. In this action, thebolt stopper 13 is effective to prevent the bolt 12.from coming out of thebolt hole 11. The rightward slide of the slidingbed 3 causes thelinks 5 to rotate, in the direction of the arrow B shown in Fig. 5, and allows thepressing bed 4 to slide downward along the flank of the lower frame 1. This looses the urging pressure between theupper frame 2 and theceiling 19, allowing an easy removed of thepartition wall 21. - Fig. 9 is a sectional view of another embodiment of a partition wall fastening unit in accordance with the present invention. Referring to Fig. 9, a combination of
rollers 3A and connectingrods 3B substituting the slidingbed 3 is connected with thepressing bed 4 by a pair oflinks 5. A drive means similar to that which is utilized for the embodiment shown in Figs. 1 through 7 (not shown in Fig. 9) slides the combination of therollers 3A and the connectingrods 3B from side to side in the direction of the arrow C, causing thepressing bed 4 to move upward and downward, resulting in the same final effects as those attained in the embodiment shown in Figs. 1 through 7. As is utilized in this embodiment, thepressing bed 4 may be directly mounted with thespacer 17 rather than through theupper frame 2 and the compression springs 16 arranged around thespring supporting rods 15, causing simplicity in construction and economization in production cost. - Fig. 10 is a fragmentary, sectional view of a modification of the drive mechanism for the partition wall fastening unit in accordance with the present invention: Referring to Fig. 10, a rotation of a
worm gear 31 causes a rotating of aworm wheel 32 and further a rotation of abolt 12, which slides the slidingbed 3 from side to side in the direction of the arrow C and causes thelinks 5 to move the pressing bed upward and downward. This enables a manual operation from the position facing the front or back of the partition wall rather than from the position facing the edge of the partition wall, eliminating the recess which is indispensable for the embodiment shown in Figs. 1 through 7. - Fig. 11 is a partly sectional view of another embodiment of the partition wall fastening unit in accordance with the present invention. Referring to Fig. 11, the
slidings bed 3 and thepressing bed 4 are arranged in the lower frame 1, and two different groups oflinks 5 rotatably connect the lower frame 1 with the slidingbed 3 and the slidingbed 3 with thepressing bed 4 respectively. The slidingbed 3 is driven by awire 33 and a drive mechanism consisting of alever 34 which pulls thewire 33 and the slidingbed 3 to move thepressing bed 4 upward and downward, and aleaf spring 35 which holds thelever 34 at either an upper position or a lower position. This shortens the time required for application and removed of the partition wall fastening unit. - Fig. 12 is a partly sectional view showing another modification of the drive mechanism to be compressed with the partition wall fastening unit in accordance with the present invention. Referring to Fig. 12, a recess is defined in the
bracket 10 in which arotatable hut 36 having a plurality of a cross-shaped recesses 37 is disposed. Thebolt 12 screwed with thenut 36 which is driven by means of a tool to be fitted with the cross-shaped recess 37, is allowed to move the slidingbed 3 back and forth, resulting in the same effects as for the embodiment shown in Figs. 1 through 7. - Fig. 13 shows another preferred embodiment of a partition wall fastening unit according to the present invention with the unit being shown as being applied to a window frame. In Fig. 13, the fastening unit is mounted between a
ceiling 52 and awindow frame assembly 54 and comprises a slidingbed 56 which is slidably disposed on an upper frame 54a ofwindow frame assembly 54. The slidingbed 56 has at its left end provided with ahead 58 having formed therein a threadedbore 58a extending in a horizontal direction. A portion of abolt 60 is screwed into the threadedbore 58a of thehead 58 to slidably move the slidingbed 56 rightward or leftward. Thebolt 60 extends through a bore 62a of aflange 62 secured to the.upper frame 54a at an extreme end thereof. Connected to an intermediate portion of the bolt is sstopper 66 which prevents excessive leftward movement of thebolt 60. A pair oflinks 68 each in the form of a plate are connected between the slidingbed 56 and apressing bed 70 which has a vertical guide 70a adapted to be slidably guided by theflange 62 during raising and lowering movement of thepressing bed 70. Thefastening unit 50 thus arranged operates in the same manner as previously described with reference to previous enbodiments to fixedly support thewindow frame assembly 54 to theceiling 52. - Figs, 14 to 17 show another preferred embodiment of a fastening unit according to the present invention, with the same reference numerals indicating the same component parts as shown in Fig. 13. The fastening unit disclosed in Figs. 14 to 17 is similar in construction as that shown in Fig. 13 except that the unit is also provided with a
compression spring 72 to resiliently support the partition wall or window frame assembly against the ceiling. As best shown in Figs. 15 to 17, the slidingbed 56 has first and secondvertical portions bed 56. Thecompression spring 72 is disposed on thebolt 60 at a position between thevertical portion 56b and the head 58' to urge the head 58' rightward as viewed in Figs. 14 to 17. With this arrangement, when thebolt 60 is turned from a position shown in Fig. 15 to a pesition shown in Fig. 16, the head 58' is pulled leftward against the force of thecompression spring 72 so that the slidingbed 56 is moved leftward by the action of thespring 72. This raises thepressing bed 70 upward, thereby resiliently supporting the partition wall or window frame assembly (not shown) to the ceiling. Fig. 17 shows a state in which thepression bed 70 is positioned in its upper most location. - It will now be apparent from the foregoing description that- in accordance with the present invention the partition wall fastening unit can be readily put into a practical application to fasten a partition wall between a ceiling and a floor with the durable and satisfactory performance without requiring any prior work applicable to houses or buildings, and can be easily removed without remaining any ugly appearance on any part of houses or buildings. Further, it will be apparent from the foregoing description that the partition wall fastening unit in accordance with the present invention allows a wide variely of layout with a less expense for application and removal.
- Although the above description is concentrated on the case where the partition wall fastening unit is mounted in the
recess 25 defined on top of thepartition wall 21, the partition wall fastening unit may be fitted in a recess defined at the bottom of thepartition wall 21. It is also possible to apply 2 sets of the partition wall fastening units to be fitted both on top of and at the bottom of thepartition wall 21. Further, although the above description is concentrated on the case where the partition wall fastening unit is mounted in arecess 25 defined in thepartition wall 21, the partition wall fastening unit may be manufactured integrally with thepartition wall 21. - While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood that various changes and modifications may be made without departing from the scope of the present invention.
- For example, the connecting links connected between the sliding bed and the pressing bed may be replaced with sliding
blocks 80 mounted on the inner surface of thepressing bed 70 and slidingblocks 80 mounted on the slidingbed 56 as shown in Fig. 18. The sliding blocks 80 and 82 may be integrally formed with thepressing bed 70 and the slidingbed 56 as indicated at 80' and 82' in Fig. 19.
