Description

  The present invention relates to a moving partition (also referred to as a moving wall; hereinafter the same), and more specifically, to a trolley mounting mechanism that travels with a glass panel suspended.

  Conventionally, moving partitions have been primarily designed to function as walls for forming a large hall as a plurality of booths as an example, so most of them are made of steel-based panels with high sound insulation and light shielding properties. there were.

  Recently, however, a moving partition mainly composed of a glass panel (hereinafter referred to as a glass moving partition) has been put into practical use so that the partitioned space can be seen from the outside. This is done according to Document 1.

  The glass moving partition uses a glass panel that is thinner than a steel panel, making it difficult to cut and drill holes for mounting and joining components, and to move the steel panel. It requires a unique device that cannot be seen in.

For example, the installation of a trolley is one of them. In other words, conventional trolley suspension bolts are installed with special mounting brackets separately, but the mounting structure of the brackets and suspension bolts is complicated, and double nuts or non-rotating screws are used to prevent rotation. There is a problem that a tool for that purpose is indispensable (see Patent Document 2).

The trolley is attached to the mounting portion by being screwed into the female screw hole .

  In the above-described configuration of the present invention, the mounting bracket has a female screw hole substantially at the center, and both sides facing the suspended beam on the front and back of the panel are fitted into notches or holes formed in the suspended beam. Since it is formed on the supported convex wing, the mounting bracket can be mounted and fixed on the suspended beam without using mounting screws or tools.

  In the present invention, the trolley main body is formed in a prismatic cross section excluding the threaded portion, while a notch formed in the tongue-like plate is fitted into the prismatic portion, and the tongue-like plate is suspended. By holding the lower beam or its outer cover to prevent the trolley main shaft from rotating, it is possible to prevent the trolley from rotating without using a double nut or a set screw, and thus no tools are required.

  In the present invention, in the moving partition in which the suspended beam disposed on both the front and back surfaces of the upper edge of the panel is bolted and the panel is pressed and clamped, a female screw hole for a trolley mount is provided near both longitudinal ends of the suspended beam. A trolley mounting portion is provided, which is provided with a notch or a hole for supporting the mounting bracket provided with the mounting bracket, and the mounting bracket is fitted to the notch or hole to fix the bracket to the suspended beam. The trolley is attached to the mounting portion by screwing the male screw formed on the main hook into the female screw hole of the mounting bracket, so that a hole or a notch is provided when the trolley is attached. No need for processing such as screwing or welding, just screwing the main screw into the mounting part by hand and inserting the concave part of the plate-like detent means into the main hook by hand. No tools needed Stop can be mounted on the trolley which has been subjected to Ri.

  In particular, in the present invention, since the mounting bracket provided with the female screw hole for the main body of the trolley is provided with a convex wing portion that fits into a notch or hole formed in the suspended beam and is supported and fixed to the beam, Mounting brackets can also be attached without using screws or tools.

  Furthermore, in the present invention, the main body of the trolley is formed in a prismatic cross section, and the concave notch formed in the tongue-like plate that is a detent metal fitting is manually inserted into the prismatic portion. Since the tongue-like plate is held by the cover of the suspended beam, the trolley detent fitting can be mounted without using a double nut or a detent screw, and therefore without using any tools.

  In the moving partition shown in FIG. 1, A is a suspended holding structure portion of the glass panel GP formed so as to press and hold the front and back surfaces of the panel along the upper edge of one glass panel GP with the suspension beams 1 and 2. , B is a trolley disposed near the left and right ends of the suspension holding structure and its mounting portion, and C is a drop seal mechanism disposed along the lower edge of the glass panel GP.

  Since an example of the trolley attachment mechanism of the present invention is applied to the suspended structure portion of the illustrated glass panel GP, the suspension structure portion will be described with reference to FIGS. 2 to 5 prior to the description of the trolley attachment mechanism.

An example of the suspended structure portion of the glass panel GP according to the present invention has the configuration schematically illustrated in FIGS. 2 to 5 and will be described below.
2 to 5, reference numerals 1 and 2 denote two suspended beams, which are metal plate members having a front shape shown in FIG. 6 and a side shape shown in FIG. The material may be any of stainless steel, steel, aluminum alloy and the like. Of the beams 1 and 2, the suspended beam 1 is provided with a plurality of bolt holes 1a, and each hole 1a is dished, but the suspended beam 2 is provided only with the bolt holes 2a. There is no fir processing. The number of screw holes 1a, 2a is an example, and is not limited to the number shown.

  Here, the suspension beams 1 and 2 have two individual configurations. For example, a suspension beam having an inverted U-shaped cross section connected at the top, or a plurality of components suspended in a plurality of pieces in the length direction. It may be a beam. Further, as illustrated in FIG. 6, the suspended beam 1 (2) has two adhesive fixing regions Ce that are centered on the mounting portions 1 c of the left and right mounting brackets 9 provided in the vicinity of the left and right sides. An intermediate portion sandwiched between the regions Ce and Ce is defined as a mechanical pressing region Me.

In the suspended beams 1 and 2, 1b is a boundary between the adhesive fixing region Ce and the mechanical pressing region Me, and slits provided at appropriate pitches in the mechanical pressing region Me. , 2 to the height of the screw hole 1a. The slit 1b is for absorbing the deformation generated in the suspended beams 1 and 2 by the slit 1b when bolts are inserted into the bolt holes 1a and 2a and tightened. Since the slit 1b is a structure for absorbing deformation, if the same effect can be obtained, the formation mode is not limited to the above illustrated example, and instead of the slit, a round hole, a long hole, or a hole is formed. You may form a row | line etc. by arrangement | positioning suitably.
In the suspended beams 1 and 2, 1 c is a mounting portion of a mount fitting 9 for a trolley formed in a notch shape between a bolt hole 1 a at the left and right outer ends and the next bolt hole 1 a, and the fitting 9 is arranged in the horizontal direction. It fits into the expanded step 1d and is held and fixed between the suspended beams 1 and 2. In the mounting portion 1c, a portion below the step portion 1d is formed to have a width (see FIG. 1) having a margin with respect to a lower portion of a main rod 11a of a trolley 11 described later. The reason for this is to allow the extra space to act as a clearance against a slight inclination generated in the main shaft 11a of the trolley 11 when the moving partition travels.

  Reference numeral 3 denotes a reaction metal fitting having a side cross-section of approximately 7 characters, and has a front shape shown in FIG. 8 and a side shape shown in FIG. The bolt holes 3a of the metal fitting 3 are provided at the same pitch as the bolt holes 1a and 2a of the suspension beams 1 and 2. Reference numeral 4 denotes a spacer having a side cross-sectional shape such that the reaction force fitting 3 is inverted. In addition, 4a is a bolt hole provided in the spacer 4, a bolt hole having the same meaning as the bolt hole 3a of the reaction force fitting 3, and 4b is a notch as a space for mounting a trolley 11 described later.

  Reference numeral 5 denotes a frictional band made of, for example, a belt-like urethane sheet disposed in a mechanical pressing region Me between the two suspended beams 1 and 2 and the opposing surface of the glass panel GP. When the suspended beams 1 and 2 are tightened (see FIG. 3), the suspended beams 1 and 2 are pressed and sandwiched between the lower half side of the suspended beams 1 and 2 and the upper edge of the glass panel GP. The sliding between the surface and the surface of the glass panel GP is prevented by the frictional force of the crushed bands 5 and 5, and the glass panel GP is pressed and held between the suspended beams 1 and 2 in the mechanical pressing region Me. Hold.

  When the tightening force is applied to the intermediate portion (mechanical pressing region Me) of the suspended beams 1 and 2 due to the tightening of the bolt 6, the beams 1 and 2 are deformed. 2 is absorbed by the slits 1b provided at equal pitches, the deformation of the suspended beams 1 and 2 due to the tightening of the bolt 6 does not extend from the tightening portion to other portions, particularly the adhesive fixing region Ce. .

  On the other hand, in FIG. 4, 7 is an adhesive applied to the inner lower flat side (adhesive fixing region Ce) in the vicinity of the left and right outer ends of the suspended beams 1 and 2. The adhesive fixing region Ce in the vicinity of the left and right side ends of the suspended beams 1 and 2 is tightened by the two bolts 8, but the spacer 4 is disposed between the two suspended beams 1 and 2. The adhesive 7 is not pushed out from between the opposed surfaces of the suspended beams 1 and 2 and the panel GP by the tightening force of the bolts 8. In other words, the spacer 4 forms an adhesive space between the opposed surfaces of the suspended beams 1 and 2 and the glass panel GP, and acts to ensure a predetermined amount of adhesive (see FIG. 5).

  4 and 5, the trolley mounting bracket 9 having a block shape is formed with a female screw 9a perpendicular to the center as shown in FIGS. 9b and 9c are formed. The mounting bracket 9 is attached to the step portion 1d (2d) (see FIG. 6) of the mounting portion 1c (2c) by the notch formed in the beams 1 and 2 before the suspended beams 1 and 2 are fastened by the bolt 6. In this state, the suspended beams 1 and 2 are fastened with bolts 6 so that the suspended beams 1 and 2 are fixed and held. As described above, the present invention does not require a stop screw or a tool for mounting the mount fitting 9 of the trolley 11 described later.

  3 and FIG. 5, the suspended beam structure 10 illustrated in FIGS. 12 to 14 is attached to the outside of the suspended beams 1 and 2 before the trolley 11 is attached. It is attached to. In the cover 10 of FIGS. 12 to 14, 10a and 10b are left and right side walls in the side cross section, 10c is a top wall formed one step down from the upper ends of the side walls 10a and 10b, and a trolley 11 is provided near the left and right outer ends of the top plate 10c. A trolley hole 10d through which the main shaft 11a passes is formed. 10e and 10f are holding walls with the lower ends bent inward, and 10g is a groove for mounting a detent metal fitting 13 to be described later provided on the inner surfaces of the side walls 10a and 10b above the top plate 10c.

  In the above-described suspension holding structure A, when the suspended beams 1 and 2 are tightened by the bolts 6 and 8 (the state shown in FIGS. 3 and 5), the beam 1 extends from one end side to the other end of the beams 1 and 2. , 2 is inserted into the cover 10 so as to be fitted outside.

  When the cover 10 is attached to the fastened beams 1 and 2, the main rod 11a of the trolley 11 is inserted from the trolley hole 10d of the cover 10, and the male screw 11b at the tip is fixed to the suspended beams 1 and 2 first. The trolley 11 is attached to the mount metal 9 by being screwed into the female screw 9 a of the mount metal 9.

  When the attachment of the trolley 11 is completed as described above, the rotation stopper 13 is attached to the main rod 11a. That is, as shown in FIG. 13, the anti-rotation bracket 13 has a tongue-like plate 13a formed of a metal plate having a width and thickness that can be inserted into the groove 10g provided on the inner surface of the cover 10. At the tip of 13a, a concave notch 13b that fits in the trolley main rod 11a so as to hold the prismatic portion is provided in the rotation stopper 13. Reference numeral 13c denotes a side of a detent fitting inserted into the groove of the cover 10.

  When the trolley 11 is attached to the anti-rotation bracket 13, the side 13c thereof is guided and supported by the groove 10g of the cover 10 and inserted into the cover 10, and when pushed by hand, the concave notch 13b at the distal end is inserted. Fits into the prismatic portion of the trolley main shaft 10a, and in combination with the holding of the metal fitting 13 in the groove 10g of the cover 10, the anti-rotation function is exhibited. End caps 14 having a function of preventing the metal fitting 13 from being detached are attached to both ends of the cover 10 to which the rotation prevention metal fitting 13 is attached.

  Thus, in the trolley mounting function of the present invention, the tongue-like plate 13a having the concave cutout portion 13b is fitted into the groove 10g provided in the cover 10 of the suspended beams 1 and 2, and the cutout portion 13b is inserted into the main shaft 11a. Since the anti-rotation action can be obtained simply by fitting it into the prismatic portion, there is no need for a double nut or screwing the anti-rotation screw or a tool for the anti-rotation.

  In the trolley 11 shown in FIGS. 1 and 15, reference numerals 11c and 11d denote two-stage horizontal traveling wheels that are rotatably mounted on the upper portion of the main shaft 11a. Reference numeral 12 denotes a box-shaped truck having rails 12a and 12b for supporting and transferring the traveling wheels 11c and 11d. The truck 12 is laid on the ceiling side of the building.
