However, if the door cock is arranged on the side surface of the drive cylinder, a part of the door tightening device protrudes, which is against the compactness. In addition, there is a problem in that the piping work for the vehicle body also involves piping from the door cock and the piping from the door cock to the door tightening device, so that it is necessary to perform piping work that matches the actual product.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a vehicle door that is compactly unitized and requires minimal piping work. It is to provide a door closing device.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a door closing device for a vehicle door according to the present invention comprises a drive cylinder for opening and closing the vehicle door, which is disposed in a door opening portion, and a lid of a chamber opposite to the rod side of the drive cylinder. A vehicle door with a door-closing electromagnetic valve that switches air supply to this drive cylinder integrally attached to the body, and an internal passage from the air-supply hole provided in this lid to the door-closing electromagnetic valve is formed inside the lid. In the door tightening device, a valve body having a position for communicating with a door-closing solenoid valve or a position for opening to the atmosphere is installed in the lid body in the middle of the internal passage of the lid body, and the valve body is provided with the position described above. It is provided with a manual switching means for switching.

Further, it is preferable that lock means for fixing the state where the manual switching means places the valve body in the open position is provided for the manual switching valve. Specifically, the manual switching means is an operation lever having an action point connected to the valve body, a fulcrum for support, and an operation portion for pushing and pulling toward the front side, and the locking means is an automatic lever. A lock lever urged to fall forward by heavy or biasing means, and the lock lever falls forward when the operation lever is pulled forward and engages the operation lever, Some parts can be manually engaged and disengaged.

[0008]

[Action]

 When the valve body mounted so that it is located inside the lid is switched to the communication position for the door closing solenoid valve by the manual switching means, pressure air enters the door closing solenoid valve through the internal passage from the air supply hole of the lid and the door closing is performed. By switching the solenoid valve, pressurized air is supplied to the rod side chamber or the non-rod side chamber of the drive cylinder, and the door opens and closes. When the valve body is switched to the open position for the door-closing solenoid valve by the manual switching means, the pressure air to the door-closing solenoid valve is shut off and communicates with the atmosphere, and the rod side chamber and the anti-rod side chamber of the drive cylinder are both exposed to the atmosphere. The door can be opened and closed manually. As a result, there is no need for actual piping for the valve body, and the valve is compact.

When the valve body is switched to the open position by the manual switching means, the door is opened manually, but when the passenger gets off, the hand touches the manual switching means, or the passenger pushes back the point cover that covers the manual switching means. However, the position of the manual switching means is fixed by the locking means, and the door is not closed accidentally by switching to the communication position.

Then, the assembly and the piping are completed only by connecting the copper pipe P to the L-shaped union joint 32 of FIG. Further, the valve body 35 is built in the anti-rod side lid body 14, and only the lever 36 laterally pops out of the anti-rod side lid body 14. Further, as shown by the chain double-dashed line in FIG. 1, an opening / closing window 2b is provided in the kamoi 2, and the lever 36 can be operated from inside the vehicle.

Next, the operation of the above-described door fastening device 8 will be described with reference to the piping diagram of FIG. Reference numeral 11 is a drive cylinder, 13 is a rod side cover, 14 is a non-rod side cover, and 48 is a pressurized air source. The pressure air from the pressure air source 48 enters the anti-rod side lid 14 from the air supply hole 27, reaches the door closing solenoid valve 24 via the filter 26, the door cock 25 and the internal passage 28. The door closing solenoid valve 24 is composed of a pilot switching valve 24a and a solenoid pilot valve 24b, and is connected to a passage 29 communicating with the non-rod side chamber 11b via a speed controller 33. The rod side cover 34 also has a speed controller 33 built therein, and the rod side chamber 11a is connected to the passage 30 of the door closing solenoid valve 24.

At the position shown in the figure where the electromagnetic pilot valve 24b is not excited, the pilot switching valve 24a communicates the internal passage 28 with the passage 30 leading to the rod side chamber 11a, and the door is closed. At the opposite position where the electromagnetic pilot valve 24b is excited, the pilot switching valve 24a communicates the internal passage 28 with the passage 29 leading to the opposite rod side chamber 11b, and the door is opened. When the door is automatically opened / closed, the door cock 25 is in the communication position P1 for communicating the internal passage 28 with the door closing solenoid valve 24 as shown in the figure. In an emergency, when the lever 36 of the door cock 25 is operated to switch to the opening position P2, the internal passage 28 from the door closing solenoid valve 24 to the door cock 25 is opened to the atmosphere, and both the passages 29 and 30 are open to the atmosphere. Then, the piston 15 of the drive cylinder 11 moves by an external force, and the door can be opened manually.

By the way, when the lever 36 shown in FIG. 2 is pulled to the front, the door comes to be opened manually. However, in an emergency, a rushed passenger may touch the lever 36. Since the lever 36 is engaged by the ball 47 biased in the protruding direction and the semicircular recess 45, it returns to the original solid line position when a strong force acts. Then, the valve element 35 is switched to the communication position and the door is closed, so that there is a risk that the passenger is caught. Also, since the lever 36 is not normally exposed but is covered with a transparent inspection cover, pushing the inspection cover back may apply a strong force to the lever 36. The door may close easily.

Another preferred manual switching means for solving such a problem will be described with reference to the front view of FIG. 4 and the YY sectional view of FIG. The door closing electromagnetic valve 24 is attached to the lid body 14, and the valve body 35 is provided on the lid body 14 as in the case of FIGS. 1 and 2. The entire door-fastening device of FIG. 5 is attached to an oblique vehicle body 2a along the curve of the ceiling and tilted downward. The inspection lid 52 is opened toward the front by a hinge 53 for operating the operation lever 51 described below. A knob 52a for fixing is attached to the inspection lid 52.

A first plate 54 is attached to the lid body 14, a second plate 55 is attached to the first plate 54, and both plates 54 and 55 are attached to the lid body 14 with bolts 56 (see FIG. 4). It is fastened together. A support shaft 57 can be inserted into the upper end of the first plate 54, and the operation lever 51 is pivotally supported by using the support shaft 57 as a fulcrum. Further, the holding member 58 is attached to the first plate 54 to fix the pushing position of the operating lever 51, but the operating lever 51 is shaken by a strong force of a person from the pushing position to the two-dot chain line pulling position. Move. A working pin 59 is provided on the base side of the operating lever 51, and the long hole 60 of the valve body 35 is inserted into the working pin 59.

Further, the second plate 55 is provided with a boss portion 62 into which the hinge pin 61 can be inserted, and a lock lever 63 is pivotally supported by the hinge pin 61 as a fulcrum. A concave portion 64 is provided at the tip of the lock lever 63, and the concave portion 64 is locked by being fitted into the operation plate 65 at the tip of the operation lever 51. When the operation lever 51 is in the push-in position indicated by the solid line, the portion of the operation plate 65 pushes the lock lever 63, which is an oblique inverted position. Since the operation lever 51 is inclined, when the operation lever 51 is pulled toward the front as shown by the two-dot chain line position, the operation lever 51 falls down by its own weight and the recess 64 is fitted and engaged with the operation plate 65 like the two-dot chain line. When the lock lever 63 is manually pushed to the inverted position, the lock lever 63 is disengaged and the operation lever 51 can be pushed.

According to the above-described manual operation means, when the inspection lid 52 is opened to the state of the alternate long and two short dashes line and the operating lever 51 is pulled from the solid line position to the alternate long and two short dashes position, the lock lever 63 is moved from the inverted position of the solid line to the vertical position. It falls down to the horizontal position of the dotted line by its own weight, and the recess 64 and the operation plate 65 engage. Therefore, even if a rushed passenger touches the operation lever 51 or pushes the inspection lid 52, the pulling position of the operation lever 51 toward the front is fixed, and the door once opened is careless. Never close. In a calm state, the lock lever 63 can be pushed up by hand and the operation lever 51 can be pushed in, and the door can be closed. When the inverted position of the lock lever 63 is not slanted, it is urged by a push spring or the like so as to be directed in the horizontal direction of the chain double-dashed line.

In the above-described embodiment, the belt-type pulling mechanism has been described, but it is also possible to use a rack and pinion type. Further, the present invention is not limited to a door that separates two doors to the left and right, and the present invention can be applied to a door tightening device that opens and closes one door to one side and does not have a pulling mechanism.
