DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding body support structure usable for, for example, a sunroof of a passenger car.

[0002]

2. Description of the Related Art Sunroofs used in passenger cars are:
An opening is formed in the vehicle roof, and front and rear guide rails fixed to the vehicle roof are disposed on the left and right sides of the opening, and a panel for opening and closing the opening is guided by the guide rail so as to be slidable back and forth. I have. The panel has a mounting frame on the outer periphery of the lower surface, a seal (weather strip) is mounted on the mounting frame, a support member is extended downward, and a slider (shoe) is provided on the support member. Are slidably disposed in a guide groove of a guide portion having a substantially U-shaped cross section of the guide rail in a longitudinal direction, and the slider is provided with a resilient portion for abutting against a guide surface of the guide groove.

[0003]

A slider for supporting such a sliding body composed of a panel, a mounting frame, a support member and the like on a guide rail has a reduced sliding resistance and has a play between the slider and the guide rail. In order to reduce the pressure, an elastically deforming elastic portion is provided on the upper surface side sliding with the guide rail.
However, since it is difficult to precisely control the amount of elastic deformation, the resilient portion is usually large, so that the panel rises greatly during running (causing vertical deflection) and is provided between the panel and the opening. The seal may be displaced to an unusual position, impairing its original function, or damaging the resilient portion itself.

Further, although a pair of right and left sliders is provided and engaged with the left and right guide rails, the position in the right and left direction is not precisely controlled, and the sliding body is slightly moved in the right and left direction. (Left / right deflection) may reduce the original function of the seal. An object of the present invention is to provide a sliding member support structure capable of solving such a problem of the related art. SUMMARY OF THE INVENTION An object of the present invention is to provide a sliding member support structure capable of precisely controlling the horizontal deflection and / or the vertical deflection of a slider in a guide groove.

[0005]

A first concrete means for solving the problems in the present invention is that a slide 3 is provided on a slide 2, and the slide 3 is substantially coaxial with a guide rail 4. In a sliding member supporting structure in which a sliding member 3 is provided slidably in a longitudinal direction within a guide groove a of a letter-shaped guide portion A, and a resilient portion 5 is provided on the slider 3 to abut against the upper surface of the guide groove a. Between the upper surface of the slider 3 and the upper surface of the guide groove a,
The difference is that a deflection management means 7 for limiting the deflection of the slider 3 in the vertical and / or horizontal directions is provided.

[0006] Thereby, the vertical direction of the slider 3 and / or
Alternatively, the vertical and horizontal deflections of the sliding body 2 are reduced by restricting the horizontal deflection slightly and appropriately. A second specific means for solving the problem in the present invention is that a pair of left and right sliders 3 are provided on a sliding body 2 for opening and closing an opening 12 formed in a vehicle roof 11. Are slidably disposed in the guide groove a of the guide portion A having a substantially U-shaped cross section of the left and right guide rails 4 fixed to the vehicle roof 11, and the slider 3 has an elastic pressure on the upper surface of the guide groove a. In the sliding member supporting structure in which the elastic portion 5 is provided to be in contact, an uneven portion 8 is formed on the upper surface of the guide groove a along the front-rear direction, and the uneven portion 8 is formed near the elastic portion 5 of the slider 3. An engaging portion 9 for engaging and restricting the left and right position is formed, and a vertical gap H between the uneven portion 8 and the engaging portion 9 is formed to be smaller than the elastic deformation amount T of the elastic portion 5. That is.

[0007] With this, the deflection in the left-right direction is controlled by the concave-convex engagement of the slider 3 with the upper surface of the guide groove a.
The vertical gap H makes it possible to finely and appropriately restrict the elastic deformation of the resilient portion 5, and the opening 12 and the sliding body 2 are controlled by precise control of the vertical and horizontal deflection of the slider 3. The function of the seal 13 provided between them is prevented from deteriorating. A third specific means for solving the problem in the present invention is, in addition to the first or second specific means, a guide surface 6 on which the resilient portion 5 abuts on the upper surface of the guide groove a and a back surface of the guide surface 6 on the inner side. A concave portion 8a is formed, and the slider 3 has a resilient portion 5 on its upper surface and a convex engaging portion 9a that engages with the concave portion 8a on the back side.
Is formed.

Thus, the recess 8a of the guide groove a and the convex engaging portion 9a of the slider 3 finely and appropriately restrict the vertical and / or horizontal deflection of the slider 3. The management means 7 can be easily configured. A fourth specific means for solving the problem in the present invention is, in addition to the first or second specific means, a guide surface 6 on which the resilient portion 5 is in contact with the upper surface of the guide groove a and a convex on the back side thereof. The slider 3 is provided with a resilient portion 5 on the upper surface and a concave engaging portion 9b for engaging with the convex portion 8b on the inner side.

With this arrangement, the concave portion 8a of the guide groove a and the convex engaging portion 9a of the slider 3 finely and appropriately restrict the vertical and / or horizontal deflection of the slider 3. The management means 7 can be easily configured. A fifth specific means for solving the problem in the present invention is that, in addition to any one of the first to fourth specific means, the slider 3 is formed of a synthetic resin, An end is integrally formed with the main body 15, and an intermediate part is lifted from the main body 15 via a space 16. In the space 16, an elastic member 17 for pressing the elastic pressing portion 5 upward is arranged. That is.

As a result, the slider 3 can be easily formed and assembled, and a sufficient elastic force can be applied to the elastic portion 5.

Embodiments of the present invention will be described below with reference to the drawings. In the first embodiment shown in FIGS. 1 to 5, reference numeral 10 denotes a sunroof provided on a vehicle roof 11 of an automobile or the like. The vehicle roof 11 has a rectangular upper opening 12 formed therein. Is opened and closed by a panel 20 made of glass or synthetic resin. Reference numeral 4 denotes a pair of left and right guide rails. The left and right guide rails 4 are connected to each other at a front portion and a middle portion or a rear portion to form a frame, or are attached to a separately formed frame. On the side,
An inner opening 21 located below the upper opening 12 is formed.

The panel 20 has a mounting frame 22 mounted on the outer periphery of the panel plate and a seal 13 mounted thereon.
Has been fixed. At the front of each of the left and right support brackets 23, a front support member 24, which is substantially L-shaped in front view, is provided so as to be vertically adjustable. A slider 3 provided at the lower end of the front support member 24 The first guide portion A1 is slidably guided back and forth. The seal 13, the panel 20,
Mounting frame 22, support bracket 23 and front support member 2
4 to open and close the upper opening 12 with the slider 3 or the like.
The sliding body 2 is supported by the guide rail 4 so as to be movable back and forth through the guide rail 4.

Although not shown, a guide rail 4 is provided at an intermediate portion or a rear portion of each of the left and right support brackets 23.
A vertical drive mechanism is provided between the front panel and the rear panel, by pushing and pulling the drive cable 25, the panel 20 is tilted up or down at the rear from the position in which the upper opening 12 is completely closed, and then moved backward. It is configured to be fully open. The guide rail 4 has a second guide rail located closer to the center of the vehicle roof than the first guide portion A1.
The sunshade 26 is guided by the second guide portion A2 via the slider 3 so as to be able to move back and forth, and the sunshade 26 can open and close the inner opening 21. There is a sliding body slidably supported by the guide rail 4 like the panel 20.

The first guide portion A1 of the guide rail 4
And the second guide portion A2 have a symmetrical shape and a substantially U-shaped cross section, and the inside thereof is formed with guide grooves a1 and a2, and the slider 3 slides in the longitudinal direction (front-back direction). It is freely inserted. Slider 3 mounted on front support member 24 (slider 3 mounted on sunshade 26 is the same)
Is formed of a synthetic resin, and has a fitting hole 15a in the main body portion 15 to be fitted into the front support member 24 made of a plate material. The arch-shaped resilient portion 5 is integrally formed from the front and rear ends of the main body portion 15. A space 16 is formed between the main body 15 and the resilient portion 5, and an elastic member 17 is disposed in the space 16.

The elastic member 17 is a leaf spring having an arch shape at the center and U-shaped ends at both ends, and resiliently presses the resilient portion 5 upward to float. Guide surface 6 on the upper surface of guide groove a of guide rail 4
You will be suppressed. On the upper surface of the guide groove a of the guide portion A, a concave portion (concavo-convex portion) 8a along the front-rear direction is formed on the back side of the guide surface 6 with which the resilient portion 5 slides.
A convex engaging portion 9a that can engage with the concave portion 8a is formed on the back side of the elastic portion 5 of the slider 3.

The protruding engaging portion 9a is arranged separately from the resilient portion 5 with a gap therebetween, and has an arcuate upper surface and a shorter dimension in the front-rear direction than the resilient portion 5. The vertical dimension (compression allowance of the elastic member 17) of the remaining space in which the elastic member 17 of the space 16 is inserted is the maximum amount of elastic deformation T at which the elastic portion 5 can be elastically deformed. Within the range of the elastic deformation amount T, the resilient portion 5 has a sufficient elastic restoring force, and the upper surface fluctuates up and down, absorbs the unevenness of the guide surface 6 and reduces the sliding resistance. Can be elastically supported when floating.

The gap H between the top surface (upper surface) of the convex engaging portion 9a and the inner surface (upper surface) of the concave portion 8a is defined by the convex engaging portion 9a.
Is the maximum dimension which can move up and down, the gap H is smaller than the elastic deformation T, for example, is set to about 20 to 40%, and the top surface of the convex engaging portion 9a is Due to the contact, the elastic deformation of the elastic portion 5 is limited.
That is, the convex engaging portion 9a and the concave portion 8a constitute the deflection control means 7, and the size of the gap H is determined by the elastic pressure portion 5 of the slider 3.
Is smaller than the elastic deformation amount T, for example, if the elastic deformation amount T is 1 to 2 mm, the dimension of the gap H on the convex engagement portion 9a is 0.2 to 0.7 mm, When the top surface of the convex engaging portion 9a comes into contact with the inner surface of the concave portion 8a, the elastic deformation of the resilient portion 5 is greatly restricted,
Is reduced to a dimension of 0.7 mm or less. The dimension of the gap H is 0.4 mm
The following is preferable, and it is optimal to precisely control the thickness in the range of 0.2 to 0.3 mm.

As described above, the convex engaging portion 9a and the concave portion 8a
By configuring the deflection control means 7 with the above, the elastic deformation of the elastic portion 5 can be reduced and the vertical deflection of the sliding body 2 can be precisely controlled, and compared with the relationship between the elastic portion 5 and the guide surface 6. Therefore, the width dimension in the left-right direction may be narrow, so that a portion that must be precision-processed can be limited to a narrow range.
The side surface of the convex engaging portion 9a overlaps with the inner surface of the concave portion 8a so as to be able to abut, so that the slider 3 hardly moves in the lateral direction (width direction) within the guide groove a. Left and right positions are regulated.

The deflection control means 7 can precisely control not only the vertical deflection of the sliding member 2 but also the horizontal deflection to reduce the loss of the function of the seal 13 provided on the panel 20 due to the vertical deflection. Breakage of the resilient portion 5 itself can be more reliably prevented. The slider 3 is inserted into the guide groove a from the front and rear ends of the guide rail 4.
a can be prevented from falling by the engagement of the concave portion 8a with the concave portion 8a, and assembling of the sunroof 10 is facilitated. Also, the guide groove a
A convex portion 27 is formed on the inner surface of the slider 3 so that the sliding resistance with the slider 3 can be reduced. However, the convex portion 27 may be formed on the slider 3 side.

FIG. 6 shows a second embodiment of the present invention, in which a guide surface 6 is provided on the upper surface of a guide groove a of a guide portion A.
A convex portion (concavo-convex portion) 8b extending in the front-rear direction is integrally formed further on the back side, whereas a concave portion engageable with the protruding portion 8b on the back side of the resilient portion 5 of the slider 3 is formed. The engaging portion 9b is formed. The concave engagement portion 9b has a groove bottom substantially parallel to the upper surface of the resilient portion 5, and the highest position of the groove bottom is opposed to the top surface (upper surface) of the projection 8b via the gap H. The child 3 is lifted up and down by the vertical dimension corresponding to the gap H, and the concave engaging portion 9b and the convex portion 8b come into contact with each other, thereby restricting the elastic deformation of the resilient portion 5 as in the first embodiment. Thus, vertical deflection of the sliding body 2 is restricted.

The concave engaging portion 9b and the convex portion 8b constitute a deflection control means 7. In addition to the vertical deflection control, the concave engaging portion 9b and the convex portion 8b abut in the left and right direction. Thus, the left-right movement of the slider 3 is restricted, and the deflection of the slider 3 in the left-right direction is also managed. In the second embodiment, since the protrusion 8b is formed on the upper surface of the guide groove a over substantially the entire length of the guide rail 4, it seems that the material is increased at first glance, but the protrusion 8b is reinforced. Since it serves as a rib, the thickness of the guide portion A can be reduced.

FIG. 7 shows a third embodiment of the present invention, in which a guide surface 6 is provided on an upper surface of a guide groove a of a guide portion A.
On the front side, a protruding portion (concavo-convex portion) 8 c is formed along the front-rear direction. On the other hand, on the front side of the resilient portion 5 of the slider 3, the protruding portion can contact the guide surface 6. A convex engaging portion 9a that can be engaged in the left-right direction is integrally formed with 8c. The upper surface of the convex engaging portion 9a has an arc shape and can contact the common guide surface 6 like the resilient portion 5, and when the sliding body 2 is not lifted, a gap H between the sliding surface 2 and the guide surface 6 is formed. When the sliding member 2 rises, the sliding member 2 comes into contact with the sliding member 2 to reduce the elastic deformation of the resilient portion 5 to the dimension of the gap H so that the elastic deformation does not become the elastic deformation amount T.

The convex portion 8c is not involved in restricting the elastic deformation of the elastic portion 5, and is engaged even when the convex engaging portion 9a is separated from the guide surface 6, so that the slider 3 in the left-right direction can be used. Only position control. Therefore, if only the vertical runout management is performed by the runout management means 7, the convex portion 8c can be omitted. Note that the present invention is not limited to the above embodiment, and can be variously modified. For example, the present invention can be applied not only to the slider 3 of the panel 20 and the sunshade 26 but also to other members which are guided and moved by the guide rails 4 and can be used not only for the sunroof but also for various machines. . Further, the elastic member 17 may use rubber or the like instead of the leaf spring.

Further, in each embodiment, the deflection managing means 7 increases the gap H formed between the concave and convex portion 8 and the engaging portion 9 to be larger than the elastic deformation amount T to reduce the vertical deflection. It is also possible to precisely manage only the horizontal runout without management.

[0025]

According to the present invention described in detail above, the horizontal and / or vertical deflection of the slider, which slidably supports the sliding member on the guide rail, in the guide groove can be precisely and precisely controlled. Easy to manage.
