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 since the size of the opening hole is quite large and it is difficult to predict the position of the human body or other obstacles, 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, which poses many problems in practical application, and considering roof space, the safety device should be as compact and simple in structure 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 This is a safety device for preventing the sliding roof from closing due to the presence of an obstacle in the sliding roof. a detection plate body separated from the movable plate corresponding to approximately the entire length of the measurement plate, and at least one pressure type detector held between the fixed plate and each movable plate; is capable of moving near and far and swinging relative to the fixed plate.

To explain in detail the embodiment shown below, Fig. 1 is an overall plan view of one example of a sliding roof using an embodiment of the safety device of the present invention, and Figs. 2 to 5 show various parts of the main structure of the device. Although this is a detailed view, in FIG. 1, 1; is the roof of a vehicle such as a passenger car. Needless to say, the roof 12 is integral with the vehicle body, and the target position of the roof 12 is An opening 128 as a window hole is opened in the required shape and size, and in this opening 12a, as shown in the figure, the inner peripheral window frame 8 is laid across the strained layer, and the opening 12a A sliding roof 10 is provided that can be slid open and closed, and as shown in the figure, slides into the roof 12 to open an opening 12a.

These may be exactly the same as conventional sliding roofs of this type, but in such sliding roofs, the present invention has the following features: , A detection plate body consisting of a fixed base frame 2 and a cover plate 3 overlapping one end of the frame 2 is installed over three peripheries of the U-shape shown in the figure.
Furthermore, a detection plate body consisting of the base frame 2 and the cover plate 3 is similarly installed in a straight line over the entire length on one edge of the sliding roof 10 corresponding to the one side that overlaps. The detector 1, which itself can be compressed and deformed, is housed in the detectors 2 and 3 in a sandwiched manner.

That is, by opening the detection plate body consisting of the fixed base frame 2 containing the detector 1 and the movable cover plate 3 around the four peripheries of the opening 12a, obstacles existing within the opening 12a can be detected. By contacting and pressing the detection plate body, the detector 1 itself is compressed and deformed to prevent the target sliding roof 1o from closing.The structure of the detection plate body 2゜3 and the detector 1 will be described in detail below. Describe.

That is, as shown in FIGS. 2 to 5, the structure of each main part is as follows.
The base plate 2 is superimposed on the upper surface of the inner window frame 8, one edge of the base plate 2 is fixed to the window frame 8 side with screws 7, and the other edge of the base plate 2 protrudes inward from the inner edge 8a of the window frame 8. The movable cover plate 3 has an elongated hole 4 in one side edge located midway through the base plate 2, and the elongated hole 4 is connected to the fulcrum sleeve 5 on the side of the plate 2. The cover plate 3 is slidably engaged with the cover plate 3, and is pivotally fixed in a slidable and swingable manner via screws 6 screwed into the sleeve 5 and washers 11, and the other side edge of the cover plate 3 is also provided with an arc-shaped clamping member. The detector 1 is sandwiched between the edges 3a and the edges 2a and 3c of the plates 2 and 3.

As shown in the third figure, the detector 1 has an electrolytic solution 1d sealed in an elastic tube 1a, and electrodes 1c at both ends.

1C is a pressure type detector attached together with lead wires te and 1e, and on the outer periphery of the elastic tube 1a there is a locking convex portion 1b that is engaged with the clamping edges 2a and 3a of both the plates 2 and 3.
, lb are provided, the plates 2 and 3 are securely fixed without fear of displacement or movement.

In addition, cover '7' rate 3 is multiple pieces and base plate 2
In the embodiment, the base brakes 1 to 2 and the cover plate 3 are formed to have the same dimensions, and at least one detector 1 is provided on each cover plate 3. For example, the cover plate 3 moves and swings relative to the base plate 2 without being elastically deformed by contact with an obstacle, so that the detector 1 can be pressed.

According to the device of the present invention, in the state shown in FIG. 1 when the sliding roof 10 is open, the obstacle P existing in the opening 12a is detected from each direction shown in When it comes into contact with the plate bodies 2 and 3, it responds within the range shown on line a4-b in the figure.

That is, in the figure, when the obstacle P contacts and presses in each direction (■) and (■), the upper cover plate 3 compresses the detector 1,
Since the enclosed electrolyte 1d moves in the length direction of the detector 1, the elastic tube 1a stretches and is connected to the electrodes 1c at both ends.
, 1c senses this, thereby cutting off the motor and power source that drive the opening and closing of the sliding roof 10, or locking the closing mechanism of the roof 1o, making it impossible to close it and ensuring safety.

In the case of contact pressure in the directions ■ and ■ in the figure, the elastic tube 1a is compressed and deformed downward in the detector 1, and
In response to contact pressure from this direction, the elastic tube 1a is compressed and deformed laterally.

This a-! When the detector 1 is compressively deformed in the range of 4b, the locking protrusions 1b and lb of the elastic tube 1a are locked and held by the clamping edges 2a and 3a, thereby preventing the detector 1 from detaching or moving. There is no fear at all.

In this case, the movable cover plate 3 will slide using the fulcrum sleeve 5 as a guide through the elongated hole 4 in response to compression from ■ and It can be freely oscillated and deformed using the fulcrum as a fulcrum.

In the safety device according to the present invention, the detection plate bodies 2 and 3 are provided to surround the entire circumference of the opening 12a along the periphery of the opening 12a and one side of the sliding roof 10. With the built-in structure, the robot always responds accurately and quickly no matter what position or direction the obstacle P exists within the opening 12a.

That is, a plurality of movable plates correspond to approximately the entire length of the fixed plate, and can move near and far from the fixed plate and swing, and at least one detector is sandwiched between the fixed plate and the movable plate. Since the detectors are configured to be pressed and operated by the operation of the movable plate, there is no need to provide the detectors along the entire length of the fixed plate, and even if they are installed at large intervals, they can be operated by the movable plate, and can be manufactured at low cost. It is easy to assemble, has high durability, and can reliably detect obstacles.
