Description

  The present invention relates to a partition that can take the form of a mechanical curtain or partition wall, and more particularly, in a building, for example, a general public to organize a traffic blocking area and, if necessary, a crowd. The present invention relates to a vertically movable partition that is used to prevent access to the space or to change or partition the shape of a space that can be used in a building.

  Security gate-type security partitions are well known and can take a horizontal bar-type system, for example to close the front of an open store in a shopping center or on a street It moves across the approach path of the shop. These types of movable security gates always require space for storage near the area to be protected in order to house the gate elements when not in use. Instead, existing “roll-up” security gates are stored in the ceiling space when not in use. This type of gate is severely limited in width and height. This is because the roller is supported only at its end and cannot be deformed under the load of the gate.

  Miles Peterson, U.S. Pat. No. 5,062,464, issued Nov. 5, 1991, describes and illustrates a wall divider, which provides a rigid wall portion. A pan-rack-shaped structure that can be folded vertically and moved to a storage position is used. The movable wall divider system has similar storage and structural support issues, and Peterson's movable wall divider is a ceiling storage for wall dividers and all Providing a single permanent location for the siding avoids these problems so that the load on the building support structure does not change. This is because the siding plate is assumed to move laterally. Furthermore, this wall system design allows partitions of all widths and heights to lift and support the partition at a number of points in the width direction. This makes it possible to fold rather than roll up the partition.

The pantograph structure proposed by the structure of the Peterson patent is similar to that found in small baby gates. That is, a series of elongate members are coupled together so as to be axially rotatable at intervals so as to provide a series of diamond shapes over the length of the gate. In a single (not multiple) pantograph structure, a pair of members of similar dimensions are connected so as to be pivotable at their midpoints. The ends of one pair of these members are pivotally connected to a corresponding pair of other, similar length, similarly pivotable members at an intermediate point, and to another pair. . The midpoints of these members are aligned in the longitudinal direction to form opposing longitudinal vertices of diamond shape. The other opposing corners of these diamond shapes are formed by axially rotating the ends of adjacent pairs of intersecting members and serve as the lateral apexes of the diamond shape. The pantograph structure expands and contracts vertically. The pantograph structure is useful in these fields. This is because forces acting in the vertical direction, i.e. in the direction of expanding and contracting the pantograph, are equally transmitted through all the members of the pantograph structure. Moreover, when reducing the structure, all vertices of the pantograph formed by the intersecting points of the members will reach their final fully reduced position at the same time. That is, the longitudinal apex of the diamond shape that moves toward the other end during reduction at one end of the pantograph structure moves at a much faster speed than the apex of the diamond shape at the other end.
U.S. Pat.No. 5,062,464

  It is an object of the present invention to provide a vertically movable wall or other type of partition based on these pantograph principles.

In accordance with one aspect of the present invention, a partition is provided that is movable upward to an open position and movable downward to a closed or lowered position. The partition includes three or more rows of elongated members configured in a similar shape, and the elongated members in each row are arranged to form a pantograph that forms a diamond shape aligned in a row in the longitudinal direction. The rows are spaced apart to form the plane of the curtain, and oriented so that the diamond shape of the pantograph operates in a plane that makes an angle of 90 ° with the plane of the curtain. In adjacent rows, a large number of bars are fixed at right angles to the rows and in parallel with intervals so as to connect the rows. Means for raising and lowering the row at the same speed causes the pantograph to contract when the curtain is in the open position and expands the pantograph when the curtain is in the closed position.

  In one embodiment of the invention, particularly suitable for use as a security gate, the partition is further provided with locking means for fixing the partition in a closed position to prevent undesired opening.

  According to another embodiment of the invention, the partition takes the form of a wall. A number of siding plates other than bars are provided, and each siding plate is fixed to one pair of corresponding members between adjacent rows. The siding plate is fixed to a corresponding pair of opposite sides of the diamond shape. Means are provided for raising and lowering the rows at the same speed. When the wall is in the retracted position, the pantograph is contracted, and when the wall is in the lowered position, the pantograph is expanded. The siding board forms a vertical wall when the pantograph is expanded in the lowered position.

  In a preferred form of this particular embodiment, similar pairs of elongate members are crossed and formed between the ends of the members to form a longitudinally aligned apex connection of adjacent diamond shapes. A certain center point on the longitudinal center line of each member is fixed so as to be rotatable. Corresponding ends of these intersecting member pairs are offset laterally outward from the centerline with the ends of similar intersecting member pairs so as to form a laterally aligned apex of the diamond shape. When the rows are contracted, the longitudinal vertices of each diamond shape are folded together so that the laterally aligned vertices are more spaced apart, and the rows When the diamond is expanded, the vertical vertices of each diamond shape are further separated, and the vertices arranged in the horizontal direction are folded together. Also, in each row, a pair of similar parallel elongated members forming a pair of opposite sides of the diamond shape form a pair of opposite sides of the diamond shape and around a single similar member. Separate. The siding plates are fixed only to spaced pairs of the elongate members along the length of the row.

  The partition according to the invention has many advantages. Because the components of this partition move vertically rather than horizontally, there is no need for storage space on the side inside the area where the wall operates, and the wall is folded and stored above the area in question. Because it is done. Furthermore, since the partition does not move horizontally, the load applied to the support structure is constant. In addition, the height and width restrictions of the conventional roll-up type security gate can be avoided. This is because the wall according to the invention is lifted and supported at a number of points across its width.

  These and other advantages of the invention will become apparent upon reading the following detailed description and upon reference to the drawings.

  While the invention will be described in conjunction with the illustrated drawings, it will be understood that it is not intended to limit the invention to these embodiments. On the contrary, all examples, modifications, and equivalents are intended to be included within the spirit and scope of the invention as defined by the appended claims.

  In the following description, similar parts in a plurality of drawings are denoted by similar reference numerals.

  Referring to FIG. 1, the mechanical curtain 2 according to the present invention is partially shown in a lowered (closed) state. The curtain shown is particularly useful as a security gate. The curtain 2 is formed from a number of pantograph rows 4 of similar shape, and these pantograph rows 4 are arranged vertically spaced along the side so as to form the plane of the curtain. Each row has an upper end 6 and a lower end 8 and is composed of an elongated member 10, forming a row of diamond shapes 12 aligned in each row 4. Except for the last (upper end 6 and lower end 8) diamond shape 12 in each row 4, a pair of elongated members 10 of similar shape intersect, and in the middle between the ends of each member, the diamond shape 12 vertical Are fixed so as to be axially rotatable with respect to each other so as to form a vertical apex 14 arranged in the vertical direction. Corresponding ends of these intersecting elongate member 10 pairs are axially rotatable to form other laterally apex 16 that is laterally located at the ends with other pairs of similarly toleranced members 10 Fixed. Thus, as seen in FIG. 2a, when column 4 is stretched in the longitudinal direction, the longitudinal vertices 14 of each diamond shape 12 are further apart and the laterally disposed vertices 14 are pulled together. On the other hand, as can be seen in FIG. 12c, when the columns are reduced, the longitudinal vertices 14 of each diamond shape 12 are pulled together and the laterally arranged vertices 16 are more distant.

  The cooperating pairs of intersecting elongated members are preferably offset laterally by a central spacer 18 (see FIG. 4) on either side of the vertices 14 and 16, so that during curtain opening and closing operations It will not interfere with each other. Each spacer 18 may be provided with an opening 20 in the longitudinal direction of the longitudinal apex 14 having a function to be described later.

  Each pantograph row 4 operates so that the diamond shape 12 lies on a plane that forms an angle of 90 ° with the plane of the partition, as seen in FIG.

  A number of spaced rods 22 extend between adjacent rows 4 to secure corresponding members 10 in adjacent rows. A notch 24 (see FIG. 3) is provided along the inner edge of each diamond-shaped member 10. This notch is for accommodating a part of the corresponding bar of the diamond-shaped facing member 10 when the row is most expanded.

  As can be seen in FIG. 3, an additional fabric 25 (shown in the figure by a dashed line) may be secured to part or all of the front side region of the partition around the bar 22, this fabric being, for example, illustrated In this way, we will weave through the bar beyond one side of the diamond shape 12 in the row.

  As can be seen in FIG. 1, in order to move the partition 2 longitudinally between an upper open position and a lower closed position, a drum 30 with cables 28 is provided, and one end of each cable is wound around each drum. Put on. Each cable passes through a corresponding pulley or pulley 26 and operably connects the other end to the corresponding lower end 8 of the row 4 as shown, or extends between adjacent rows 4 at the lower end 8. It may be connected to the bar 22. For proper balance, the cable extends vertically downward from the pulley 26 through the opening 20 in the spacer at the longitudinal apex 14 and fastens to the vertical apex 14 below the corresponding row 4 Better to do.

  As can be seen in FIG. 4, the bar 22 can be mounted at the longitudinal apex 14 so as to extend outwardly toward an adjacent row. Instead, for example, a cable is wound around the pulley 31 (shown by a broken line in FIG. 3) so as to provide a pulley device (a double purchase) consisting of two single pulleys for raising and lowering the partition. The free end may be appropriately connected above the partition. Proper drive means for drums 30 (see FIGS. 2a, 2b, 2c) are provided so that each cable 28 is fed and wound in the same way for each drum 30 so that each pantograph can be closed for partitioning. Expand or contract for release.

  When designing a partition as a security gate, use a suitable conventional locking mechanism 32 (see Figures 2a and 2b), for example to secure the lower end 8 of the row 4 on or in an appropriate part of the floor under the partition. Further, it may be provided in order to cooperate with the locking mechanism 34.

  In order to balance the weight of the partitions, a number of similar bars 22 are preferred on each side of the centerline of the row of elongated members 10 (ie, on both sides of the longitudinal axis of the row through the longitudinal apex). Are fixed alternately.

  5a, 5b and 5c are schematic side elevational views showing another embodiment of the partition 2 according to the present invention. In this case, as shown in the figure, the uppermost elongated member 10 is fixed to the wall 4 or other support member 40 at its upper end 42 so that the row 4 can be pivoted. Thereby, when the drum 30 winds up the cable 28 via the corresponding pulley 26, the centerline of row 4 along the longitudinal apex 14 from the closed position (see FIG. 5a) to the open position (see FIG. 5c) The partition moves away from the support member 40 until it reaches the open position shown in FIG. 5c, and the vertical apex 14 moves the distance farthest from the support member 40. The center line of row 4 is preferably located directly below pulley 26.

  Referring to FIGS. 6, 7 and 8, another structure of the partition 2 is shown, in which each elongate member 10 in the row 4 is provided with a bend (jog) 46 as shown. Both ends 48 and 50 of each member on one side of the bent portion 36 are parallel. As seen in FIGS. 7 and 9, bar 22 extends from pair 10a of members 10 outward in both directions, and these members are similarly oriented and positioned, spaced apart from each other and diamond-shaped Twelve opposing pairs of sides are formed, and a similar single elongate member 10b does not have a bar 22 and is fixed to form the other opposite side of the diamond shape 12. These members 10b are sandwiched between and connected to the members 10a at the apexes, and are directed in the opposite direction with respect to the members 10a. When the partitions are expanded in the closing direction (see Fig. 8), the structure of the partitions is such that the vertical row of the rows of partitions 4 as shown in the figure, so that the bars are positioned vertically and nevertheless rebalance. It is allowed to alternate on both sides of the directional axis (in the embodiment of the partition shown in FIGS. 1-5, the bars are not aligned vertically). The embodiment of the row structure shown in FIGS. 6-8 requires that no rods be secured to the inner member 10b, so that the rods secured to the particular diamond-shaped 12 member 10a are aligned. During contraction, the opposite member 10b is not directed in the opposite direction.

  In this embodiment, the cable 28 passes through an opening 52 provided in the center of the lowest bar 22 extending between the vertical apexes 14 of the row 4 as shown.

  In FIG. 10, for the sake of aesthetics, an additional set of bars 56 extending between the rows 4 and arranged in the horizontal direction may be provided as necessary.

In the embodiment shown in FIG. 11, similar extensions 60 are disposed laterally on the surface formed by each diamond shape 12 and are disposed laterally from the apex 16. The end of each extension 60 is secured by suitable conventional means so as to slide up and down within the corresponding track 62. In this embodiment, the cable 28 is located along one edge of each pantograph row 4 as shown and its free end is fixed to the lowermost extension 52. The track 62 may be supported by existing structures such as walls or posts, or may be free standing.

  As shown in FIG. 11, a fabric 25 can be mounted on the bar 22 as needed for purposes such as preventing visibility through decoration, covering, or partitioning, or for other functions. This fabric may be anti-ballistic, such as Kevlar®, or a solar fabric for solar thermal control or energy generation (ie manufactured from a solar cell material that can convert light energy into electrical energy) It may be).

  The arrangement of the dividers in FIG. 12 is similar to that in FIG. 11 but has no fabric and is in a moving position between an open position and a closed position. It is shown in an elevation view. In FIG. 13, the partition of FIG. 11 is shown in more detail in side elevation again with the fabric 58 shown.

  The partition according to the present invention is relatively simple to construct and operate when used for crime prevention, solar thermal control or otherwise, and can be easily visually appealed, and the prior art Will have all the above advantages over the security gates and the like.

  Referring to FIG. 14, a partition wall 72 according to the present invention is shown in an intermediate position between an upper storage position and a lowered position, where the wall is in a vertical direction (see FIGS. 16 and 18). As seen in FIGS. 14 and 15, there are provided a number of identical rows 74 of elongated members 76, with each row 74 member 76 forming a vertically aligned diamond-shaped 80 row. 78 to form 78 (see FIG. 15). Although two rows are shown in FIG. 14, any number of rows can be spaced apart to form a suitably wide wall. These rows are arranged in the vertical plane of the wall, and the pantograph diamond shape 80 is located in a plane that makes an angle of 90 ° to the wall and is oriented to operate.

  A number of siding plates 82 fixed to the member 76 are provided, details of which will be discussed later. As shown, each panel 82 is fixed to a pair of corresponding members 76 in adjacent rows. These siding plates are fastened to corresponding pairs 84 on opposite sides of the diamond shape.

  Appropriate means are provided for moving the wall siding 82 to the retracted or lowered position in the form of a drum 88 fixed to a linear shaft 86 for power drive. One end of each cable 90 is wound around a corresponding drum 88. Each cable 90 passes through a corresponding pulley or pulley 92, and the other end of the cable is operatively connected to the lower end 94 of the corresponding row 74, for example as shown, or at the lower end 94 of the adjacent row 74. It connects with the bar material (not shown) extended in between.

  As seen in FIG. 15, pairs of similarly shaped elongate members 76 intersect and are pivotally coupled at a center point 98 between the member ends. This center point is on the longitudinal centerline 100 of each member. As a result, adjacent and vertically arranged vertices 102 of the adjacent diamond shape 80 are formed. The corresponding end 104 of the pair 96 of intersecting members 76 is pivotally connected to the end 104 of the pair of intersecting members 76 of the same type at points 105 and 106, respectively. Are offset laterally to the outside of the centerline 100 so as to form the laterally arranged vertices 108 of the diamond shapes 80, thereby causing the longitudinal vertices of each diamond shape 80 to contract when the row 74 is contracted. 102 are folded together so that the laterally arranged vertices 108 become more distant, and when expanding the row 74, the longitudinal vertices 102 of each diamond shape 80 become more distant and laterally The arranged vertices 108 attract each other.

  In each row 74, a similar pair of elongated members 76a and 76b (see FIG. 14) that form opposing sides of the diamond shape 80 are similar single members that form the other opposing sides of the diamond shape. Separated from 76c. The siding plate 82 is secured only to a pair of spaced elongated members 76a and 76b along the length of the row. These siding plates are not directly fixed to the single member 76c.

  As seen in FIG. 14, each siding plate 82 is from one of a pair of parallel elongated members that form a pair of opposing sides of a diamond shape, such as member 76a and an adjacent similar pair of parallel elongated members. Secured to facing member 76b, in this context members 76a and 76b are separate from row 74 but adjacent. According to the method of attaching the siding plate 82 to the member 76, when the pantograph is operated between the contracted (retracted) position and the lowered position, the siding plate 82 does not interfere with the operation of the single member 76c, and The reverse is also true.

  The structure of the partition wall according to the feature of the present invention makes it possible to fix a pair of siding plates to the elongated members 76a and 76b facing the siding plates with a gap as shown in FIG. A void in the space between these sidings provides sound insulation or thermal insulation. Alternatively, the space may be filled with an insulating material (not shown), for example.

  Also, as seen in FIGS. 15 and 16, the use of pivot points 105 and 106 that are laterally offset from the outside of the centerline of the pair of intersecting members that form laterally arranged vertices and intersect The formation of the coplanar engagement ends 112 and 114 of the member 96 is such that, as shown, the row elongate member 76 is perfectly aligned when the row is in the lowered position as shown in FIGS. It is possible to reach the direction. This feature is such that when the partition wall is in the lowered position, the siding plate itself forms a single or unbroken vertical wall, or a wall having the desired properties depending on the features provided in the siding plate, It is possible to align them so as to form the same plane in the vertical direction. As seen in FIG. 18, when in this position, there is only a small space between the siding plates in the horizontal direction, and a narrow but somewhat wider vertical space remains between the siding plates.

  The siding can be made of any suitable material, such as metal, plastic or composite material. Part of the siding may be made of a transparent material, which can be applied to provide a completely transparent wall or window wall.

  The wall can be of the desired width by adding a similar row 74 of an appropriate number of elongated members 76 and a siding plate 82 adjacent and integral therewith.

  The structure of the partition wall according to the present invention has a simple and economical structure and is easy to operate.

  It is therefore evident that a partition according to the present invention is provided that fully satisfies the aforementioned objects, goals and advantages. While the invention has been described in conjunction with the illustrated embodiments thereof, it will be apparent to those skilled in the art that many selections, improvements, and modifications will be made in light of the foregoing description. Accordingly, it is intended that all such selections, modifications and variations be included within the spirit and broad scope of the present invention.
