Description

[Detailed description of the invention] This invention detects when a human body or other obstacle is present in the opening of the sliding roof of a vehicle, ship, etc., which is opened and closed by the roof. Relating to a safety device designed to prevent closure.

As is known, in a passenger vehicle, a ship, etc., an opening window hole is provided on the roof of the vehicle body such as the driver's cab, a sliding roof is provided in the window hole so that it can be opened and closed, and the vehicle runs with this open at any time.
It has been put into practical use in recent years, and it is known that there are types that open and close automatically and types that open and close manually.

At this time, it does not matter if it is done automatically or manually, but if there is a part of the human body (head, neck, arms, fingers, etc.) or other obstacles inside the opening window, it is impossible to close the sliding roof accidentally. It goes without saying that this poses a danger to humans, but also causes troubles such as damage or malfunction of the sliding roof opening/closing mechanism.This danger is especially great when the sliding roof opens/closes automatically, and the safety device is designed to prevent this. Various types have been proposed, but the size of the opening hole is quite large, and it is difficult to predict the position of the human body or other obstacles, so it is difficult to predict the position of the human body or other obstacles. It is necessary to ensure reliable and wide coverage based on the assumption, but there are many problems that arise in practical implementation, and considering the roof space, the safety device should be as compact and simple as possible. In addition, it is required that the obstacle detection accuracy is high and the durability is high.

The present invention was developed to satisfy these requirements, and its feature is that when a sliding roof installed on the roof of a vehicle, ship, etc. is In a safety device for preventing the sliding roof from closing due to the presence of an obstacle in the sliding roof, a fixed plate is provided in a protruding manner around the roof opening and on one side of the sliding roof, and a plurality of detectors are installed at intervals. A plurality of detection plates are provided that surround substantially the entire length of the fixed plate, and are movable toward and away from the fixed plate, and each detection plate is provided with at least an actuating member that operates the detection plate by approaching the detector. The point is that one is built-in.

The present invention will be described in detail with reference to the embodiments shown below. FIG. 1 is an overall plan view of the device of the present invention, and FIGS. 2 to 5 show detailed structural views of the main parts of the device. In FIG. 1, 15 is the roof of a passenger car, etc., which is integrated with the vehicle body, 15a is an opening made in the roof 15 at the desired position, and 12 is an opening. Part 15
It is an inner window frame laid over the entire inner circumference of a
3 is a sliding roof that seals with the window frame 12 to close the opening 15a, and as shown in the figure, slides into the roof 15 to open the opening 15a; these structures are different from conventional ones. This is the same type of sliding roof.

The present invention provides such a sliding roof with a fixed base plate 4 and a fixed base plate 4 on the inner window frame 12, except for one side that overlaps with the sliding roof 13, as shown in the figure. The detection plate body, which is separated from the movable detection plate 7 attached to the detection plate 7, is laid in a U-shape (not shown),
A detector 1 is built into this detection plate body.

At the same time, a similar detection plate body and detector 1 are installed on one side of the sliding roof 13.

As a result, the entire periphery of the opening 15a is surrounded by the detection plate body 7, and as will be described later, an obstacle existing within the opening 15a comes into contact with the plate body.
The detector 1 reacts immediately, making it impossible to close the sliding roof 13 and ensuring safety.

The detailed structure of the relationship between the base plate 4, the detection plate 7, the detection plate 1, the body, and the detector 1 is as illustrated successively in FIGS. 2 to 5.

That is, in FIGS. 2 to 5, one side edge of the base plate 4 is fixed on the upper surface of the inner peripheral window frame 12 with screws 14, etc., and the inner peripheral edge 1 of the window frame 12 of the plate 4 is fixed.
As shown in FIG. 3, the detector 1 is installed in the cylindrical portion 4a as shown in FIG. 3 on the other side edge projecting inward from the detector 2a.

That is, the detector 1 used in the present invention is a switch-type detector using a reed switch, and the reed switch is covered from both ends with a protective tube 2 having elasticity, but the central portion of the entire circumference of the protective tube 2 is etc., some of them are reed switch 1
The opening 16 is formed so that a part of the main body of the switch is exposed to the outer circumference, and the reed switch is covered with a protective tube 2, and is further supported by a split support fitting 3 as shown in the fourth figure. is inserted into the cylindrical part 4a of the base plate 4,
After the positioning is performed, both ends of the support fitting 3 are crushed and fixed, and at this time, the cylindrical portion 4a is similarly opened in accordance with the opening 16.

On the other hand, the detection plate 7 has a shape that completely surrounds the cylindrical part 4a in which the detector 1 is built from the middle of the base plate 4 as shown in the figure, and the detection plate 7
is installed by fixing the elongated hole 11 provided on one side edge of the plate 7 with the snub 8 and washer 9 screw 10 provided on the base plate 4 side. It is slidable and pivoted using the screw 10 and the sleeve 8 as a fulcrum.

On the inner surface of the detection plate 7 facing the cylindrical portion 4a,
A permanent magnet 5 is located at a position corresponding to the opening 16 of the detector 1.
A plate spring 6 is attached to the outside of the cylindrical portion 4a, and a plate spring 6 is attached to the outside of the cylindrical portion 4a.
is supported at only one end and is able to move and swing freely relative to the base plates 1 to 4, and does not elastically deform itself, but when the detection plate 7 approaches the base plate 4, it becomes a permanent magnet. 5 is brought close to the reed switch, thereby allowing the permanent magnet 5 to move freely into and out of the operating area of the reed switch.

In this case, the detection plate body may be made of 91 pieces over the entire length on one side of the sliding roof 13,
For the inner peripheral window frame 12, a plurality of detection plates may be divided and arranged in parallel over the entire length, and each detection plate has at least one permanent magnet 5 as an actuating member. It suffices if there is a detector 1 and arranged correspondingly to the detector 1.
Further, the detector 1 does not have to be a reed switch, but the same effect can be obtained as long as the switch contact can be opened and closed by the permanent magnet 5 or other actuating member.

According to the safety device of the present invention, when the sliding roof 13 is opened as shown in the first figure, an obstacle P existing in the opening 15a is moved from the direction of the arrow (■) as shown in FIG. When the detection plate 7 is pressed into contact with the detection plate 7 as shown in FIG. Detector 1 installed inside the cylindrical part 4a
Since the reed switch enters the operating area of the thorny area, the separation point of the reed switch adheres, so the detection by the detector 1 can stop the closing motor (motor) of the sliding roof 13, for example, or shut down the closing mechanism. Safety is ensured by preventing the roof 13 from closing by locking or stopping the roof 13.

Similarly, in FIG. 2, when the obstacle P comes into contact with and presses the detection plate 7 from the direction shown in the figure, the plate 7 slides inward with its elongated hole 11 using the snowblade 8 as a guide, and the plate spring 6 is similarly compressed. At the same time, the permanent magnet 5 also moves into the activation area of the limit switch and, via the contact bonding, the closing of the sliding roof 13 is likewise prevented.

In the device of the present invention, a plurality of detection plates surround substantially the entire length of the fixed plate, are movable toward and away from the fixed plate, and have at least one actuating member for detection on the fixed plate side. Since the sensor is configured to be activated by proximity to the fixed plate, there is no need to provide the detector and the actuating member along the entire length of the fixed plate.
Even if the detection plates are provided at intervals, even if an obstacle comes into contact with the detection plate at a position that does not correspond to the detection plate, each detection plate can move close to the fixed plate, so that the detection of the obstacle is reliable. , can increase safety more,
Moreover, it can be produced at low cost, has a simple configuration, and is highly durable.
