Description

[Detailed description of the invention] (Industrial application field) The present invention covers the opening of the vehicle roof with a cover member consisting of a front cover, a rear cover, a hood member, etc., which can be opened and closed to provide lighting inside the vehicle interior.
A hood-type sunroof device designed to provide ventilation and an open feeling, especially when the cover member is closed or closed, the hood member tension of the hood-type sunroof device is such that the left and right ends of the hood member are in close contact with the vehicle roof surface. Regarding equipment.

(Prior Art) Conventionally, an opening is formed in the roof of a vehicle, and the upper surface of this opening is covered with a cover member, which can be opened and closed.
A hood-type sunroof device, which is folded and stored at the rear of the vehicle roof when opened, has been used in various countries for a long time because of its wide opening and relatively simple structure.

The cover member is integrated with a front cover and a rear cover provided at the front and rear of the hood member, and the front cover is moved back and forth manually or automatically via guide rails and opening/closing devices provided on the left and right sides of the opening. The cover member is configured to be opened and closed using the cover member.

The cover member ensures good adhesion between the side edges of the hood member and the top surface of the vehicle roof when closed, especially at the time of closing to seal the top surface in close contact with the top surface of the vehicle roof, and also protects against wind pressure from outside the vehicle. In order to maintain good adhesion even when the vehicle is in use, a tension member such as a belt or cable and a tension applying means such as a spring member are provided between the front cover and the rear cover at the left and right ends of the hood member. (Jitsukai 61-
(Refer to Publication No. 78020).

The tension member is foldable together with the hood member when the cover member is opened, and at the time of closing after the cover member is closed, the tension member compensates for the flexibility of the hood member and
It has the effect of bringing the side ends into close contact with the top surface of the vehicle roof, and although the tension member itself can expand and contract to some extent, it is difficult to achieve perfect contact due to the close contact of the hood member, especially as high-speed driving is required these days. When the vehicle is running, the sides of the hood member lose contact with the roof surface of the vehicle due to wind pressure, and there is a risk that wind or rain may enter the vehicle interior.

Therefore, the tension applying means is provided. This tension applying means is provided with a spring member between the front cover, the rear cover, or either one and the tension member, and the front cover moves forward at the time of closing after the cover member is closed, thereby pulling the spring member. Tension is applied to the tension member, and the biasing force of the tension member causes the sides of the hood member to firmly adhere to the top surface of the vehicle roof after closing, and the wind pressure when the vehicle is running causes the hood member to tighten. When the side part floats upward, the tension of the spring member can be increased to further strengthen its biasing force.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional technology, the spring member uses a tension coil spring, which may rub against the hood member due to repeated loads, damaging the hood member or causing surging. In addition, the connection between the hook part of the spring member and the tension member or cover is easily damaged, and the maximum allowable stress is generally lower than that of compression springs (see JIS B2704). It is necessary to use a device with a large diameter and a large cylinder diameter, making it difficult to improve durability and make it more compact.

The present invention provides a hood for a hood-type sunroof device that solves the problems of the prior art by using a compressed elastic body as a spring member and configuring the compressed elastic body to be fitted onto the outside of the cylindrical part. An object of the present invention is to provide a member tensioning device.

(Means for Solving the Problems) The specific means for solving the problems in the present invention are a rear cover fixed to the rear side of the opening in the vehicle roof, and a rear cover that slides back and forth on guide rails provided on both left and right sides of the opening. a movably supported front cover; a hood member that covers the rear cover and the front cover and is connected to them at its front and rear ends and opens and closes an opening by sliding the front cover back and forth;
A tension member provided on the left and right sides of the hood member and whose front and rear ends are connected to the rear cover and the front cover, and an opening provided between at least one end of the tension member and the cover connected to the tension member. In the hood member tensioning device for a hood type sunroof device, the tensioning device has a tensioning means for applying tension to the tensioning member by moving the front cover forward when the front cover is closed. It has a compressible elastic body which is fitted and locked at one end, an elastic body receiving part provided on the cover side and which locks the other end of the compressible elastic body, and a cylindrical part into which the compressive elastic body is externally fitted. .

(Function) When the front cover is moved forward via the slider to bring the cover member into the opening closed state (approximately the state shown by the solid line in Figure 3), the tension members provided at both left and right ends of the hood member I become nervous. From this state, if you move the slider further forward,
The front cover is moved forward and downward via the opening/closing device so as to come into close contact with the opening surrounding material and the upper surface of the front part of the vehicle roof (the state shown in FIG. 4), thereby further tensioning the tension member. This tension causes the elastic body receiving part of the bracket to move toward the cable end side and compress the compression elastic body, and the repulsive force of the elastic body is applied to the tension member, causing both ends of the hood member to move against the top surface of the vehicle roof. Press it elastically to make it stick. Since the elastic body is fitted onto the outside of the bracket tube, its compression and expansion operations are performed without rubbing against the top member.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 4, reference numeral 1 denotes the roof of a vehicle such as a passenger car, on which an opening 2 having a rectangular shape in plan view is formed, and an opening surrounding material 3 forming the periphery of this opening 2.

On both left and right sides of the opening surrounding material 3, guide rails 3A in the front and rear direction are provided, and a recess 3B is formed at the front end of the guide rail 3A. Slider 8 on each of the left and right guide rails 3A
is arranged slidably through the shoe, and can be driven in the front-rear direction by a drive section 9 having a cable, gear mechanism, etc.

The cover member 4 has a hood member 5 made of a flexible material, and a front cover 6 and a rear cover 7 attached to the front and rear lower surfaces of the hood member 5, and is configured to be foldable and expandable. There is.

As shown in FIG. 3, a bracket 10 is fixed to the rear lower surface of the front cover 6, and a cam member 11 having a cam groove 11a is fixed to the bracket 10. It is slidably supported by the guide rail 3A. The front shoe 12 of the cam member 11 can be inserted into the recess 3B of the guide rail 3A. A pin 8a protruding laterally from the slider 8 is engaged with the cam groove 11a.

The back and forth drive of the slider 8 is transmitted to the cam member 11 via the pin 8a to move the front cover 6 back and forth, and when the front cover 6 is located in front of the opening 2, the front shoe 12 of the cam member 11 faces the guide rail recess 3B,
The pin 8a slides in the cam groove 11a, and the front part of the front cover 6 swings up and down, and the forward drive of the slider 8 presses the front cover 6 against the front upper surface of the opening surrounding material 3 to close the cover. The slider 8, the cam member 11, the recess 3B, etc. constitute an opening/closing device 13 that moves the front cover 6 back and forth and closes the front cover.

While the front cover 6 is movable back and forth, the rear cover 7 is fixed to the rear part of the opening surrounding material 3, and the hood member 5 is folded and expanded as the front cover 6 moves back and forth. In order to improve the folding of the canopy member 5 and to provide tension in the lateral direction, a sliding member 14 that slides on the guide rail 3A is provided between the front and rear covers 6 and 7 below the canopy member 5. A horizontal aggregate 15 and a floating aggregate 17 held by a connecting member 16 which is connected to the horizontal aggregate 15 in a rearwardly projecting manner are provided. Horizontal aggregate 15
There are two sets of front and rear combinations of floating aggregates 17, and the floating aggregates 17 are also provided at the rear of the front cover 6, and each of the aggregates 15 and 17 is connected to the lower surface of the hood member 5.

When the cover member 4 is folded backward to open the opening 2, the action of the horizontal aggregates 15 and floating aggregates 17 results in the state shown by the two-dot chain line in FIG. 3.

1, 5 to 8, the canopy member 5 of the cover member 4 has a front portion 5a formed in the shape of a bag that is open at the rear, and a protector 6 at the front end of the bag-shaped front portion 5a.
The front cover 6 with the attached part a is inserted and fixed with double-sided adhesive tape 24 or the like.

The left and right end portions of the canopy member 5 at the midway point in the front and back direction are as follows:
As shown in FIGS. 1 and 8, the side end 5f is bent downward and welded at two places with a welder to form a bag-shaped part, and the front end of this side end 5f is the front end of the bag-shaped part. It is fixed to the portion 5a by a welder.

The rear part of the hood member 5, the rear cover 7, and the side ends 5
Although the relationship with f is not shown, it can be made the same as the relationship between the front portion 5a, the front cover 6, and the side end portion 5f.

A tension member 23 made of a wire material such as a cable is inserted into the bag-shaped portion formed by the left and right side ends 5f of the hood member 5, and the front and rear ends of this tension member 23 are It is connected to a front cover 6 and a rear cover 7.

A tension applying means 20 is provided between both or one of the front cover 6 and the rear cover 7 and the tension member 23. The connection between the end of the tensioning member 23, which is not provided with the tensioning means 20, and the cover is carried out via rivets or pins.

Figures 5 to 7 show the front cover 6 and the tension member 23.
A bracket 21 is fixed to the bottom side of the front cover 6 with a rivet 21c or the like.
A cylindrical portion 21a having an axis in the front-rear direction and a concentric elastic body receiving portion 21b are integrally formed at the side end of the bracket 21.

The cylindrical portion 21a has a hollow cylindrical shape (in FIG. 7, it has a cylindrical shape with the front cover 6), and has a compression elastic body 22 formed of a coiled compression spring inside. is inserted, and the tension member 23 is passed through the elastic body 22.

The elastic body receiving part 21b has a cylindrical shape with a diameter smaller than that of the cylindrical part 21a, and the tension member 23 is inserted through the inside of the elastic body receiving part 21b, and one end of the elastic body 22 is in contact with the end surface of the tension member 23.

A cable end 23a is fixed to the tip of the tension member 23, and an elastic body 2 is attached to this cable end 23a.
The other ends of 2 are in contact with each other.

Therefore, the compression elastic body 22 is fitted onto the tension member 23, one end of which is locked to the distal end of the tension member 23, and the other end of which is locked to the elastic body receiving portion 21b. While the expansion and contraction movements are guided, contact with the canopy member 5 is avoided. After the tension member 23 is tensioned, the front cover 6 is further tensioned.
When the elastic body receiving portion 21b moves forward, the elastic body receiving portion 21b moves closer to the cable end 23a, and the elastic body 22
is compressed within the cylindrical portion 21a. The repulsive force of the compression becomes a tension force that pulls the tension member 23, and becomes an urging force that elastically presses the side end portion of the hood member 5 against the top surface of the vehicle roof.

Incidentally, in the present invention, the cylindrical portion 21a and the elastic body receiving portion 21b are integrally molded on the bracket 21, but they may be separated, and the tension member 2
3 may be a thin belt or the like in addition to a cable, the cover member 4 may be manually opened/closed, and the compression elastic body 22 may be a compression coil spring, rubber, elastic synthetic resin, air cylinder, etc. A well-known type that generates a repulsive force through compression can be used.

(Effects of the invention) According to the invention described in detail above, the tensioning member is formed of a linear material, and the tension applying means is a compression elastic body that is fitted externally to the tensioning member and has one end locked, and a Since it has an elastic body receiving part that locks the other end of the elastic body and a cylinder part into which the compressible elastic body is fitted, the compressible elastic body is compressed when the cover member is closed, and tension is applied to the tension member. The maximum allowable stress is higher than that of a tension spring, and therefore it is possible to improve durability and make it more compact.
In addition, the cylindrical part eliminates friction between the elastic body and the canopy member, making it possible to prevent surging, and furthermore, both ends of the elastic body are locked between the elastic body receiving part and the end of the tension member. Therefore, the connecting parts such as the tension springs are less likely to be damaged and can withstand long-term use.
