Abstract

<P>PROBLEM TO BE SOLVED: To provide a folding door which prevents the gear parts of the gear hinge from being seen and prevents inserting a finger into the gear part while using a long gear hinge. <P>SOLUTION: The folding door comprises a pair of folding door panels which integrally forms a gear part having an arc-shaped cross-section and forming a plurality of tooth grooves over the entire inside length of one stile composing the folding door panel, and a connecting plate which forms gear parts at both ends, each having an arc-shaped cross-section and forming a plurality of tooth grooves engaging the tooth grooves of the stile-side gear part. The folding door panels are foldably connected by engaging the tooth grooves of the gear parts at both ends of the connecting plate with the tooth grooves of the gear parts of the folding door panels respectively. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a folding door using a connecting member having a long gear portion.

  Conventionally, folding doors using long gear hinges are well known without mentioning known documents.

  However, in the case of such conventional folding doors, the gear part of the gear hinge can be seen when the folding door is closed or opened, and the appearance is not good. However, there is a problem that not only the number of parts of the folding door is increased but also the assembly process is increased.

  In addition, as a separate cover is omitted, folding doors that are connected by attaching plate-like gear hinges only to the upper and lower ends of the folding door, so that fingers are not pinched and dust does not accumulate are mainstream, A large force acts on the gear part of the plate-shaped gear hinge every time the folding door is opened and closed, and when using a heavy folding panel such as a glass door, the gear part wears severely and cannot be used for a long time. was there.

  In order to solve the above-mentioned problems of the prior art, the present invention does not allow the gear portion of the gear hinge to be seen or the finger to be caught between the gear portions while using a long gear hinge without using a separate cover. The purpose is to provide a folding door.

  The folding door according to the present invention includes a pair of folding door panels integrally formed with a gear portion having a cross-sectional arc shape in which a plurality of tooth grooves are formed over the entire inner length of one vertical fence constituting the folding door panel, and both ends. And a connecting plate formed with a gear portion having a cross-sectional arc shape formed with a plurality of tooth grooves meshing with the tooth groove of the gear portion on the vertical shaft side, and the folding doors in the tooth grooves of the gear portions at both ends of the connecting plate. It is characterized in that it is foldably connected by engaging the tooth gaps of the respective gear portions of the panel.

Effect of the invention

  In the present invention, the gear portion of the folding door panel and the gear portion of the connecting plate are housed in the vertical fence constituting the folding door panel and are not exposed.

  1 is an overall front view of a folding door according to the present invention, FIG. 2 is a plan view of a vertical wall portion of a folding door panel, FIG. 3 is a plan view of a connecting plate, and FIG. 4 is a connection of folding door panels. FIG. 5 is a plan view in the closed state of the folding door, FIG. 6 is a plan view in the middle of opening the folding door, and FIG. 7 is a plan view in the opened state of the folding door. is there.

  In the figure, 1 is a folding door panel composed of left and right vertical fences 1-1, 1-2, upper and lower vertical fences 1-3, and a panel 1-4 such as a glass plate, which are aluminum mold members constituting the folding door of the present invention.

  2 is a gear part having a circular arc shape in which a plurality of tooth grooves 2-1... 2-1 are integrally formed over the entire inner length of one longitudinal rod 1-2.

  3 has a cross-sectional arc shape in which a plurality of tooth grooves 3-1... 3-1 meshing with the tooth grooves 2-1. It is the connection board in which the gear part 3-2 made was formed.

  Reference numeral 4 denotes an arcuate guide plate that guides the protruding portion 3-3 at the end of the connecting plate 3 so that the protruding portion 3-3 can move circularly within the vertical shaft 1-2. Reference numeral 5 denotes a protruding portion 3-3 of the connecting plate 3 Is an elastic member such as rubber so as not to directly contact the guide plate 4, and when the folding door is closed, the hook portion 3 formed on the protruding portion 3-3 of the connecting plate 3 on the part 5-1 of the elastic member 5. -3a is engaged to apply resistance.

  Next, a folding door connecting method and a standing method according to the present invention will be described based on the above configuration.

  First, the guide plate 4 and the elastic member 5 are fitted into predetermined positions of the vertical rod 1-2 of the folding door panel 1 so that the gear portion 3-2 of the connecting plate 3 and the gear portion 2 of the vertical rod 1-2 are engaged with each other. The pair of folding door panels 1 and 1 are connected to each other through the connecting plate 3 by inserting them from the upper end or lower end of the vertical fence 1-2, and the horizontal fences 1-3 are connected to the upper and lower ends of the folding door panels 1 and 1, respectively. 1-3 is installed and fixed to complete the folding door.

  The vertical fence 1-1 side without the gear portion of the folding door is appropriately pivotally attached to the upper and lower frames of the attachment frame of the opening, and the folding door is completed. (In FIG. 1, two sets of folding doors are mounted symmetrically)

  In the closed state of the folding door of FIG. 5, the hook portion 3-3a formed on the protruding portion 3-3 of the connecting plate 3 is engaged with the part 5-1 of the elastic member 5 to be applied with resistance, and wind pressure or the like. However, when the handle on the vertical shaft 1-1 side of the folding door panel 1 on the non-pivot support side is pulled, the gear portion 2 and the connecting plate 3 of the vertical shaft 1-2 are pulled. The gear portion 3-2 is folded while meshing, and the state shown in FIG.

  In the opened state of FIG. 7, the adjustment of the space between the folding door panels 1 and 1 can be freely changed by adjusting the width of the connecting plate 3.

The invention's effect

  As described above, according to the folding door according to the present invention, a pair of gear portions having a cross-sectional arc shape in which a plurality of tooth grooves are formed over the entire length of the inner side of one vertical fence constituting the folding door panel. Each of the folding door panels and a connecting plate having a gear portion having a cross-sectional arc shape in which a plurality of tooth grooves meshing with the tooth grooves of the vertical-side gear portion are formed at both ends, and the gears at both ends of the connecting plate. Since the tooth gaps of the folding door panels are meshed with the tooth gaps of the folding door panel so that they can be folded together, the folding door panel gear section and the connecting plate gear section constitute the folding door panel. The space between the two folding door panels in the folded state can be reduced by changing the width of the connecting plate without the need to take measures to cover the gear hinge part with a separate cover, unlike the conventional folding door. Place There is an effect that it changes the interval, but can provide a folding door that durable usability.

  It is the whole front view of the state where the folding door of the present invention was installed.   It is a top view of the vertical fence part of a folding door panel.   It is a top view of a connection board.   It is a principal part enlarged plan view showing the connection state of a folding door panel.   It is a top view in the closed state of the folding door.   It is a top view in the state in the middle of opening of the folding door.   It is a top view in the open state of the folding door.
