Abstract

PURPOSE: To fix a door temporarily at a specified open position so as to prevent the door from moving there by inhibiting a sliding motion of a rocking lever against a holding member with a thrust pressure which contact-presses the rocking lever. CONSTITUTION: An energizing member 10 screws a male threaded part 10a into a threaded hole 8e extending in the shaft center direction formed on the bottom of a shaft 8b of a holding member 8 and energizes a rocking lever 7 upward with a steel ball 10b, thereby contact-pressing the outer peripheral surface 7a of the rocking lever 7 in the inner surface 8d of a through hole 8c and increasing a friction resistance of the rocking lever 7 against the holding member 8. The screwing amount of the male threaded part 10a into the holding member 8 is controlled so that the thrust force which contact-presses the rocking lever 7 against the holding member may be properly controlled. When the energizing force 10 opens a door 10 against the friction resistance by the thrust force which contact-presses the rocking lever 7 against the holding member 8, and the rocking lever 7 is rocked following with the opening operation and comes to a stop at a specified opening position, the friction resistance stops the sliding motion of the rocking lever 7 with the holding member and fixes the rocking lever 7 at its released position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A temporary fixing device for an opening / closing door according to the present invention will be described below in more detail with reference to the embodiments shown in the accompanying drawings.
1 is an explanatory view showing an example in which the temporary fixing device for an opening / closing door according to the present invention is attached to a central control device for integrally controlling an automatic ticket gate, an automatic ticket vending machine and the like, and FIG. 2 is an opening / closing shown in FIG. FIG. 3 is an explanatory view showing the structure of the temporary door fixing device, and FIG. 3 is an operation explanatory view of the temporary door fixing device.

In FIG. 1, reference numeral (1) is a housing of the central control unit, and reference numeral (2) is a pair of upper and lower support plates (3) fixed to one right side edge portion on the front side of the housing (1). , 3) support shafts such as pins
(4, 4) is an open / close door attached so as to be rotatable in the horizontal direction, reference numeral (5) is a handle of the open / close door (2), and reference numeral (6) is a temporary fixing device for the open / close door according to the present invention. is there.

As shown in FIG. 1, the temporary fixing device (6) for the opening / closing door has a shaft (4, 4) serving as a rotation center axis of the opening / closing door (2) inside the housing (1). It is located on the opposite side. The opening / closing door temporary fixing device (6) includes a swing rod (7) and a holding member (8).
, A stopper (9) and a biasing member (10) (see FIGS. 1 and 2). The oscillating rod (7) is formed in the shape of a rod that is shorter than the depth dimension of the housing (1).
In the upper part of the above, the one end (7a) is fitted together with the spacer (12) into the bracket (11) which is fixed to the inner surface of the opening / closing door (2) and the pin (13) extending in the up-down direction in the bracket (11). The housing is connected so that it can swing in the horizontal direction by inserting
It extends to the (1) side. The holding member (8) has a large-diameter head (8a) in the upper part and a small-diameter shaft (8b) in the lower part, and is formed in a substantially rivet shape, and the top plate of the housing (1) is formed. The shaft (8b) is press-fitted into the bearing (15) inserted into the substantially L-shaped support member (14) fixed to the back surface of (1a) so that it can rotate in the opening / closing direction of the opening / closing door (2). It is installed. Shaft part of the holding member (8)
A through hole (8c) extending in the diametrical direction is formed in (8b), and the above-mentioned swing rod (7) is slidably inserted therein. The stopper (9) is formed in an annular shape having a diameter larger than that of the swing rod (7) and is fixed to the other end of the swing rod (7) to open the open / close door (2) and rotate in the opening direction. When this is done, it comes into contact with the shaft portion (8b) of the holding member (8) to define the maximum open position (P) of the opening / closing door (2) (see FIG. 3). The urging member (10) is a steel ball (10b) by a spring (not shown) built in the male screw part (10a).
Is a ball plunger that presses outward. The biasing member (10) has a male screw portion (10a) formed in the lower surface side of the shaft portion (8b) of the holding member (8) and extending in the axial direction.
The outer peripheral surface (7a) of the rocking rod (7) is held by the steel ball (10b) which is screwed into the e) and urges the rocking rod (7) upward.
It is pressed against the inner surface (8d) of the through hole (8c) of (8) to increase the frictional resistance of the rocking rod (7) to the holding member (8), so that the opening / closing door (2) can be opened at the desired open position. It is supposed to stop. Further, the biasing member (10) is provided with a screw hole (8) of the holding member (8).

(2) Opening / closing door even if installed slightly tilted in the opening / closing direction
(2) does not rotate in the tilt direction, and the door
The pressing force creates frictional resistance on the rocking rod (7) that does not hinder the opening / closing operation of (2).

Temporary fixing device for opening / closing door configured as described above
(6) holds the pull tab (5) of the open / close door (2) and resists the frictional resistance generated by the pressing force of the urging member (10) pressing the swinging rod (7) against the holding member (8). When the opening / closing door (2) is opened (see FIG. 3), the swing rod (7) follows the opening operation of the opening / closing door (2) and swings in the opening direction of the opening / closing door (2). Then, when the opening / closing door (2) is stopped at the desired open position (P1), the urging member (10) presses the swinging rod (7) against the holding member (8), and the frictional resistance generated by the pressing force causes The swinging rod (7) is prevented from sliding on the holding member (8), and as a result, the open / close door (2) is in its open position (P1).
Will be temporarily fixed.

In this embodiment, an example in which the temporary fixing device for the door of the present invention is applied to the central control device for integrally controlling an automatic ticket gate, an automatic ticket vending machine, etc. is explained. The temporary fixing device for use is a device in which an opening / closing door is attached to one side edge portion of the housing or a part of one side surface of the housing so as to be horizontally rotatable.
For example, the present invention can be applied to various devices such as a traffic signal control device for controlling a traffic signal light device, a vending machine for beverages, cigarettes, etc., a switchboard, or an air conditioner control device.

[0010]

As described above, the temporary fixing device for an opening / closing door of the present invention has a swinging rod which has one end horizontally swingably connected to the inner surface of the opening / closing door and extends toward the housing, and a housing. A holding member that is rotatably attached to the body in the opening / closing direction of the opening / closing door and slidably holds the swinging rod, and is fixed to the other end of the swinging rod when the opening / closing door is rotated in the opening direction. A stopper that abuts on the holding member and defines the maximum opening position of the opening / closing door; and a biasing member that is fixed to the holding member and presses the swing rod against the holding member so that the opening / closing door can be stopped at a predetermined opening position. Therefore, even if the housing is installed in the installation part with the opening / closing door slightly inclined in the opening direction or the closing direction, the biasing member presses the swinging rod against the holding member. The pressure prevents the swing rod from sliding on the holding member, so The opening and closing door can be temporarily fixed,
Therefore, the opening / closing door that rotates in the closing direction does not interfere with work, and the adjacent device does not get damaged by the opening / closing door that rotates in the opening direction.
