Description

[Detailed description of the invention] Industrial field of application This invention relates to door opening/closing devices for toy trains, buses, etc.

Prior Art This type of conventional door opening/closing device for toy trains, buses, etc. has a button protruding from the roof that is connected to a crank-type operating lever, which makes the operating mechanism complicated and increases costs. Nakatsuta.

Problems to be solved by this invention The first objective of this invention is to improve the reliability of operation. That is, when one of the opening/closing buttons protruding from the roof is pressed, the door opens, and when the other is pressed, the door closes, and in both cases, this state is maintained and the operation is smooth. Second, it is easy to assemble. The number of parts is small, the structure of the shaft support is rational, and there are few fixing points.
Thirdly, the structure is robust and can withstand hard use. Fourthly, it has a small number of component parts and can be manufactured at low cost.

Measures to solve the problem: An operating button with a stopper at the bottom end is fitted and protruded from below into a bearing tube with holes opened in the top and bottom of the vehicle roof.
The operating shaft, which is integrally attached to the lower end of each button, is connected to the connection hole at the upper left and right ends of the T-shaped interlocking rod, which is supported by a support shaft that projects laterally from the inner surface of the vehicle body end plate, and is also attached to the inner surface of the vehicle body end plate. The actuating plate is slidably engaged to the left and right with a guide frame that is screwed and fixed to a supporting base that protrudes laterally, and the central vertical operation part of the T-shaped interlocking rod is inserted into the communication hole of this actuating plate. The right door is connected to the operation movement of the operating plate through the insertion and left and right along the guide frame, and the door side end of the operating plate is formed into a chevron-shaped operating surface, and is supported separately on the inside of the vehicle body side plate by upper and lower support rods. and the left door are arranged so as to be closed at all times by applying a traction spring between both supports, and interlocking rods integrally provided with the respective support rods are disposed opposite to the chevron-shaped operation surface of the actuating plate, and this operation surface is It is characterized by being inserted into the interlocking rods and pushed open, pushing the left and right doors open against the traction spring, and holding the left and right doors open by inserting them up to the parallel part following the chevron-shaped operating surface of the actuating plate. It is found in the door opening/closing devices of toy trains, buses, etc.

Embodiment Hereinafter, this invention will be explained with reference to a drawing which is an embodiment. 1a and 1b are operation buttons, and bearing tubes 2a and 2 are provided on the left and right sides at required intervals on the roof 2 of the train car body.
b, are fitted with upward retainers 3a, 3b at their lower ends, and are integrally connected to operating shafts 5a, 5b having connecting flanges 4a, 4b at their lower parts.

Reference numeral 6 denotes a T-shaped interlocking rod, which is swingably supported by a support shaft 9 integrally formed on the inner surface of the car body end plate 8 in a horizontal mounting hole 7 formed in the center of the upper part, and vertically penetrates the left and right ends of the upper part. The lower portions of the operating shafts 5a, 5b are fitted into the connecting holes 10a, 10b, and the connecting flanges 4a, 4 are inserted.
It is supported so that it can swing from side to side by applying b,
An operating section 11 is formed which extends downward from the center of the top.

Reference numeral 13 denotes a guide frame, and a support base 1 has both end mounting portions 14a and 14b integrally formed on the inner surface of the vehicle body end plate 8.
2 is fixed with screws.

Reference numeral 15 denotes a door opening/closing actuation plate, which is associated with a connection hole 16 into which the operation part 11 of the T-shaped interlocking rod 6 is inserted and connected, and whose side corresponding to the door is formed into a chevron-shaped operation surface 17 inclined left and right. .

Reference numeral 18 indicates a window plate on the vehicle body side, and reference numeral 19 indicates a right door, which is disposed inside the window plate 18 on the vehicle body side. It is connected to one slope of the chevron-shaped operation surface 17 of the actuating plate 15 by the right door interlocking rod 21 which is extended to the right door interlocking rod 21 .

22 is the left door, and the left door upper and lower support rods 23
a and 23b, and is connected to the other slope of the chevron-shaped operation surface 17 by the left door interlocking lever 24.

The guide frame 13 consists of a fitting part 25 into which the engagement tube 27 with a retaining flange of the actuating plate 15 is fitted, and a guide part 26 into which the engagement tube 27 is fitted and slid.
In addition, the right door upper support rod 20a and the left door upper support rod 23
"a" refers to vertical support rods 20a, 20b and 23a, 23b which are provided with hanging shafts 28, 29, on which door closing springs 30 are hung, and which are slidable back and forth.
is pulled around the reference protrusion 31 on the actuating plate 15, and the doors 19, 22 are automatically closed. 32 is a vehicle body bottom plate.

Function Since the embodiment of this invention is constructed as described above, when the operation button 1a is pressed, it descends and
The operation shaft 5a rotates the T-shaped interlocking rod 6 to rotate the operation part 11 toward the door, rotates the connected operation plate 15 along the guide frame 13, and rotates the operation plate 15 along the guide frame 13, thereby rotating the operation part 11 toward the door.
is inserted between the right door interlocking rod 21 and the left door interlocking rod 24, and is pushed open both front and back against the spring 30, so that the right door 19 and the left door 22, which are integrally connected to these, are moved forward and backward. It moves and opens. In the final stage of pushing the door open, the parallel stopper surfaces 17a, 17a following the chevron-shaped operation surface 17 are inserted between them, so that the compression force exerted by the spring 30 from the front and back can be supported, and the door can be maintained in the open state. .

Next, when the opposite operation button 1b is pressed, the T-shaped interlocking rod 6 rotates in the opposite direction, moving the operating plate 15 to the guide frame 1.
3 in the opposite direction and close the door along the chevron-shaped operation surface 17.

Effects of the invention Since this invention is as described above,
By alternately pressing two operation buttons protruding from the roof of the vehicle, the two doors can be opened and closed to the left and right with the feeling of operating a switch button.

In addition, the connection from the above structure to the actuation plate that opens and closes the door from the operation button is fixed to the support shaft and support stand protruding from the inner surface of the end plate of the vehicle body by means of bearings and screws.
It can be made by a glyph interlocking rod and a guide frame,
All of these parts are made of synthetic resin moldings to reduce manufacturing costs, and since the bottom of the vehicle body can be left open, attachment of each part and overall assembly can be made extremely easy.

In addition, since the door opening/closing operation mechanism of the actuating plate has a chevron-shaped operating surface, it can be opened and closed at the rate of descent of the button, giving a sense of play, and the actuating plate can be pushed into a parallel plane. It has a simple structure and is effective as a stopper for keeping the door open.

Therefore, this device has increased commercial value as a door opening/closing device for toy trains, buses, etc., and has many practical effects.
