Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an accordion-shaped partition partition particularly suitable for hanging on a circular arc-shaped rail.

(Prior art) In a partitioning device constructed by connecting a set of four arms protruding in an X shape from the outside of a boss in sequence at the outer ends of each arm, the boss and the arms Various configurations are possible for the attachment part.

For example, the Chiyoban device devised in JP-A-53-107134 has two shafts 6 in the connecting part 5 (corresponding to the boss in the present invention).
A and 6b are provided, and a front piece 1a and a back piece 1b are attached to this.
(corresponding to the arms in this proposal) are inserted separately, and the It consists of four rotating pieces (corresponding to the arms of this proposal) that are integrally formed.
A vane plate 5 (corresponding to the arm of the present invention) is fitted in the vertical direction (corresponding to the boss of the present invention).

(Problems to be solved by the invention) However, the structure of the Chiyo number of JP-A No. 53-107134 is weak and the shafts 6a and 6b in particular are easily broken, and the A thin pivoting portion 4' is provided for each rotating piece 4. The base of the rotating piece 4 has a narrow width corresponding to the shaft attachment part, so it is easy to break. Although there is a section, there is no rotating section, so when passing through a curved section, strain is created between the attachment section of the arm and the boss, creating resistance to the opening and closing of the partition, which may lead to malfunction.

(Means for solving the problem) This proposal was devised for the purpose of obtaining a partition panel that has a strong structure and that does not cause strain when the X-shaped panel structure passes through the arc-shaped rail. As a means for this purpose, as shown in the figure, a cylindrical groove 3 is bored in the symmetrical position of the shaft hole 2 of the boss 1, an opening 4 having a width smaller than the inner diameter of the groove is provided on the outside of the cylindrical groove 3, and a cylindrical part 6 is separately provided at the base. An X-shaped crosspiece structure 2 constructed by rotatably fitting each cylindrical part 6 of two arm plates 5 into the cylindrical groove 3, each having a steel wire insertion hole 7 at the outer end thereof. When the partition passes through the curved part of the rail, the cylindrical part 6 of each arm plate rotates appropriately within the cylindrical groove 3 of the boss, so that each arm plate and the boss This is an attempt to eliminate the tension between the two.

(Example) To explain the structure of this proposal using an example, the first

Reference numeral 3 denotes two cylindrical grooves bored at symmetrical positions in the shaft hole, and an opening 4 having a width smaller than the inner diameter of the groove is provided on the outside of the two cylindrical grooves.

Reference numeral 5 designates an arm plate, which has a cylindrical part 6 at its base, has a through hole 7 for a steel wire 8 at its outer end, and rotatably fits the cylindrical part 6 into the cylindrical groove 3 of the boss. The outer end of the arm plate is made to protrude outward from the boss to form a chiyoban structure together with the boss, the two structures are overlapped at each boss part, and the 2 parts of the shaft hole are fixed with pins 9. It consists of Note that 10 in the figure indicates a rail.

(Function, effect) In the case of this partition, several sets are arranged in sequence as shown in Figures 1 and 5, and the outer end of the arm plate of the upper member of each set is connected to the outside of the arm plate of the lower member. The arm plate 5 of each part is connected to the cylindrical part 6 of the base thereof, and is used in a continuous manner with vertical steel wires 8 overlapping at the ends.
is rotatably fitted into the cylindrical groove 3 of the boss, so the structure is strong and the rotation is smooth, especially when the rail is arranged in a circular arc shape as shown in Fig. 5. Suitable for moving partitions.
