Description

  The present invention relates to a temporary fixing structure for temporarily fixing a member such as an electronic device.

  2. Description of the Related Art Conventionally, an indicator that is suspended from a ceiling in a passenger compartment is firmly attached to the ceiling with screws so that the indicator does not drop due to vibration or the like. Since it is not preferable in design if this screwed portion is exposed in the vehicle interior, a decorative frame member called a bezel is often attached to the display so as to cover the screwed portion.

As described above, since the bezel is attached after the display body is screwed to the ceiling, the bezel is treated as a member different from the display body in the previous stage.
For example, conventionally, the bezel and the display main body are separately packed and transported. In this case, if the bezel can be packed and transported in a state where it is attached to the display main body, the cost for packing and transport can be reduced.
In addition, the clip which becomes a snap fit may be used for attachment of a bezel (for example, refer patent document 1).
Patent Document 2 discloses a connector capable of temporarily fixing between members.

JP 2007-31530 A JP 2004-156722 A

Even when distributing the bezel attached to the display body, it is necessary to remove the bezel once at the stage of attaching the display to the ceiling in the passenger compartment.
However, since the snap fit that engages and fixes the members using the elasticity of the members is firmly assembled between the members, the bezel or the display body is damaged when the bezel is removed at the stage of attaching the display. There was a possibility.
In addition, if the snap fit is not fully engaged, the bezel that has come off during packing may hit the display unit and be damaged, and the external force applied to the package may cause unexpected damage. There is also a possibility of being engaged and fixed (mainly fixed).

  On the other hand, the clip disclosed in Patent Document 1 is configured such that the members are engaged and fixed in a state where the stopper is mounted, and when the stopper is removed, the engagement is released and the member can be removed. When this clip is used for attaching the bezel, it is easy to remove the bezel, but the stopper remains attached even after the bezel is finally attached to the display body. For this reason, if the stopper is removed due to vibration during traveling, the bezel may come off and fall.

The connector disclosed in Patent Document 2 is composed of a male part and a female part into which the male part is inserted. When the male part is inserted up to the first level, the female part is temporarily fixed in a mounting hole provided in the member. It is possible to fix the female part by inserting the male part up to the second level.
However, in order to prevent the male part from being erroneously inserted up to the second stage, it is necessary to provide a complicated engagement structure for the male part and the female part. Therefore, it is difficult to manufacture the connector itself, which leads to an increase in cost of an electronic device using the connector.

  The present invention has been made to solve the above-described problems, and an object thereof is to obtain a temporary fixing structure between members that can be temporarily fixed with a simple configuration.

  The temporary fixing structure between the members according to the present invention is the temporary fixing structure between the members for temporarily fixing the first member to the second member, and is attached to an attachment rib formed on the first member. Formed on the first member alongside the mounting ribs and a clip composed of a plurality of anchor portions that are inserted into the locking holes provided in the member and elastically restored to a state of spreading outward. When the stopper rib is mounted between the first member and the second member, the plurality of anchor portions abut on the stopper rib at the temporary fixing insertion position elastically deformed inward, and the clip moves in the insertion direction. And a temporary fixing member that regulates the above.

  According to the present invention, there is an effect that temporary fixing can be performed with a simple configuration.

It is a perspective view which shows a ceiling hanging type display. It is a disassembled perspective view of the display of FIG. It is sectional drawing which shows the attachment aspect to the display apparatus main body of a bezel. It is sectional drawing which shows the temporary fix | stop structure between the members which concern on Embodiment 1 of this invention. It is sectional drawing which shows another structure of the temporary fix | stop structure between the members which concern on Embodiment 1. FIG.

Hereinafter, in order to describe the present invention in more detail, modes for carrying out the present invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
FIG. 1 is a perspective view showing a ceiling-suspended display, and FIG. 2 is an exploded perspective view of the display of FIG. In FIG. 1, a display 1 is a hanging type display installed on a ceiling in a vehicle interior. The bezel 2 is attached so as to cover the outer periphery of the display body 3A.
By pressing the open / close button 4 from the state in which the display monitor 3 is closed, the display monitor 3 is opened in the direction of the arrow in FIG. The occupant seated in the rear seat can view the video and audio through the display screen 3a of the display monitor 3 in the open state.

As shown in FIG. 2, the bezel 2 is a decorative frame member that is attached so as to cover the outer periphery of the display body 3 </ b> A. Further, the clip 5 is attached to the bezel 2 (for the sake of simplicity of description, in FIG. 2, a part of the bezel 2 is shown as being visible through the clip 5).
As will be described later with reference to FIG. 3, the clip 5 is inserted into the locking hole 7 formed in the attachment portion 6 of the display body 3 </ b> A so that the bezel 2 can be temporarily fixed and permanently fixed to the display body 3 </ b> A. (Full installation) is performed. In other words, the temporary fixing structure between the members according to the present invention is applied with the bezel 2 as the first member and the attachment portion 6 of the display body 3A as the second member.

The display body 3A includes a housing 3b for storing a circuit board and the like, and a display monitor 3 that pivots around a hinge 3c to be opened and closed, and is screwed with its rear side facing the vehicle compartment ceiling.
The bezel 2 is mounted after the display body 3A is fixed to the ceiling of the passenger compartment by screws, but before the display body 3A is fixed to the ceiling by applying the temporary fixing structure between members according to the present invention. The bezel 2 is temporarily fixed to the attachment portion 6 of the display body 3A. Thereby, since packing can be combined into one, the cost concerning packing and transportation can be reduced.

  FIG. 3 is a cross-sectional view showing how the bezel is attached to the display body, and shows a case where the bezel 2 is permanently attached to the attachment portion 6 of the display body 3A using the clip 5 having a snap-fit function. . That is, FIG. 3 shows only a configuration that functions when the bezel 2 is permanently attached to the attachment portion 6. 3A shows a state before the bezel 2 is attached to the attachment portion 6, and FIG. 3B shows a state when the bezel 2 is permanently attached to the attachment portion 6. .

A stopper rib 2 a and a mounting rib 2 b are formed on the mounting surface of the bezel 2. The stopper rib 2a is formed side by side with the mounting rib 2b and has a function of restricting movement of the clip 5 in the insertion direction. A clip 5 is attached to the upper end of the attachment rib 2b.
As shown in FIG. 3 (a), the clip 5 is composed of, for example, a plurality of anchor portions 5a having a shape that is bent outwardly, and outward in a free state (a direction away from the mounting rib 2b). It has spread.

When the clip 5 is inserted in a state where the opening edge portion of the locking hole 7 is in contact with the anchor portion 5a, the anchor portion 5a is elastically deformed inward (in a direction approaching the mounting rib 2b).
When the clip 5 is further inserted, the anchor portion 5 a is elastically deformed inward, and only the convex portion 5 a-1 is in contact with the inner wall of the locking hole 7.
Thereafter, when the clip 5 is further inserted, the convex portion 5 a-1 slides on the inner wall of the locking hole 7 in the insertion direction of the clip 5. That is, in the state where the convex portion 5a-1 is in contact with the inner wall of the locking hole 7, the reaction force due to the elastic deformation of the anchor portion 5a is large, but the contact area with the inner wall of the locking hole 7 is the smallest. Therefore, by applying a force greater than the reaction force, the clip 5 can be moved both in the insertion direction and in the extraction direction.

Next, as shown in FIG. 3B, when the convex portion 5a-1 is inserted from the opening on the opposite side of the locking hole 7 until the convex portion 5a-1 is removed, the anchor portion 5a is elastically restored to a state of spreading outward. .
At this time, the anchor portion 5a spreads outward to a state close to a free state, and the portion ahead of the convex portion 5a-1 strongly presses the opening edge of the locking hole 7 to prevent the clip 5 from coming off. In this way, the clip 5 is completely locked in the locking hole 7.
Further, the stopper rib 2a comes into contact with the mounting portion 6 side, and the clip 5 is restricted from moving in the insertion direction from the insertion position shown in FIG. Thereby, it can prevent that the anchor part 5a moves to the position which remove | deviates from the latching hole 7 completely.

4 is a cross-sectional view showing a temporary fixing structure between members according to Embodiment 1 of the present invention. FIG. 4 (a) shows a temporary fixing state, and FIG. 4 (b) shows a main fixing structure. This shows the state (mainly attached state). In the example shown in FIG. 4, supporter ribs 6 a are formed on the attachment portion 6. The supporter rib 6a is a rib for disposing the spacer ring 8 when temporarily fixed.
The spacer ring 8 is a ring-shaped temporary fixing member having a through hole 8 a through which the clip 5 passes.

First, when the bezel 2 is temporarily fixed to the mounting portion 6, the clip 5 is engaged until the end face of the stopper rib 2 a comes into contact with the peripheral edge of the through hole 8 a of the spacer ring 8 after the spacer ring 8 is arranged on the supporter rib 6 a. Insert into the blind hole 7.
At this time, the anchor portion 5a of the clip 5 is elastically deformed inward (in the direction approaching the mounting rib 2b), and only the convex portion 5a-1 is the inner wall of the locking hole 7 as shown in FIG. It becomes an insertion position (hereinafter referred to as a temporary fixing insertion position) in contact with.

Although the reaction force due to the elastic deformation of the anchor portion 5a is large at the temporary fixing insertion position, the contact area with the inner wall of the locking hole 7 is the smallest, so the clip 5 is inserted by applying a force greater than the reaction force. It can be moved both in the direction of pulling out and in the direction of pulling out.
Since the stopper rib 2a abuts against the spacer ring 8 and the movement of the clip 5 in the insertion direction is restricted, and the temporarily fixed insertion position is maintained, even if an external force is applied to the bezel 2 or the mounting portion 6, it is easy to temporarily The book is never mounted from the stop insertion position.

On the other hand, when the bezel 2 is permanently attached to the attachment portion 6, the clip 5 at the temporary fixing insertion position is pulled out from the locking hole 7 and the spacer ring 8 is removed, as shown in FIG. The clip 5 is inserted into the locking hole 7 until the end surface of the stopper rib 2 a comes into contact with the mounting portion 6.
At this time, the anchor portion 5a of the clip 5 is elastically restored and spreads outward to a state close to a free state, and is a portion ahead of the convex portion 5a-1 (a hatched portion in FIG. 4B). Strongly presses the opening edge of the locking hole 7.

  In this insertion position (hereinafter referred to as a full stop insertion position), the convex portion 5a-1 is removed from the opening on the opposite side of the locking hole 7, and the anchor portion 5a is spread outward. Thereby, the size of the anchor portion 5a including the convex portion 5a-1 in the direction parallel to the opening surface of the locking hole 7 is larger than the diameter of the locking hole 7, and the clip 5 is prevented from coming off. In this way, the clip 5 is completely locked in the locking hole 7. Further, since the stopper rib 2a is in contact with the attachment portion 6, the clip 5 is restricted from moving in the insertion direction from the final stop insertion position.

  4 shows a configuration in which when the bezel 2 is permanently mounted from the temporarily fixed state, the clip 5 is once pulled out from the locking hole 7 and then the spacer ring 8 is removed. However, the clip 5 is pulled out from the locking hole 7. You may comprise so that this mounting | wearing can be carried out. For example, when the bezel 2 is pushed in with a pressing force larger than an external force assumed during transportation, the spacer ring 8 is formed of a material in which the opening peripheral edge of the through hole 8a is broken by the stopper rib 2a. Thereby, the stopper rib 2a can break the spacer ring 8 only by pushing in the bezel 2, and the clip 5 can be further inserted from the temporarily fixed insertion position.

  FIG. 5 is a sectional view showing another configuration of the temporary fixing structure between the members according to the first embodiment, and shows a case where a sleeve 9 is used as a temporary fixing member. In FIG. 5, a sleeve 9 is a sleeve-shaped temporary fixing member including a cylindrical portion 9b through which the clip 5 passes and a flange portion 9a projecting outward from the peripheral edge of the opening of the cylindrical portion 9b. Since the sleeve 9 is attached to the locking hole 7 through the cylindrical portion 9 b, the support rib 6 a is not formed on the attachment portion 6.

When the bezel 2 is temporarily fixed to the mounting portion 6, first, after the cylindrical portion 9 b is passed through the locking hole 7 and the sleeve 9 is mounted, until the end surface of the stopper rib 2 a comes into contact with the flange portion 9 a of the sleeve 9. The clip 5 is inserted into the locking hole 7 through the cylindrical portion 9b. At this time, the anchor portion 5a of the clip 5 is elastically deformed inward inside the cylindrical portion 9b, and as shown in FIG. 5, the convex portion 5a-1 is in contact with the inner wall of the cylindrical portion 9b. This is the stop insertion position.
When the bezel 2 is permanently attached to the attachment portion 6, the clip 5 at the temporarily fixed insertion position is pulled out from the tubular portion 9 b to remove the sleeve 9, and then the clip 5 is moved until the end surface of the stopper rib 2 a abuts the attachment portion 6. Insert into the locking hole 7.

Although the spacer ring 8 and the sleeve 9 are shown as temporary fixing members, the present invention is not limited to this shape. When the temporary fixing member according to the present invention is mounted between the bezel 2 (first member) and the mounting portion 6 (second member), the plurality of anchor portions 5a are elastically deformed inward. Any shape that abuts against the stopper rib 2a at the insertion position and restricts the movement of the clip 5 in the insertion direction may be used.
For example, a small piece that can come into contact with the end face of the stopper rib 2a is used as a temporary fixing member. In this case, the bezel 2 is temporarily fixed to the attachment portion 6 by inserting the clip 5 into the locking hole 7 until the end face of the stopper rib 2a comes into contact with the small piece after the small piece is arranged on the supporter rib 6a.

  As described above, according to the first embodiment, it is attached to the attachment rib 2b formed in the bezel 2, and is elastically restored to the state where it is inserted into the locking hole 7 provided in the attachment portion 6 and spreads outward. Thus, the clip 5 including a plurality of anchor portions 5 a locked in the locking holes 7, the stopper rib 2 a formed on the bezel 2 along with the mounting rib 2 b, and the bezel 2 and the mounting portion 6 are mounted. Then, the spacer ring 8 or the sleeve 9 which is a temporary fixing member that abuts against the stopper rib 2a at the temporary fixing insertion position where the plurality of anchor portions 5a are elastically deformed inward and restricts the movement of the clip 5 in the insertion direction. Prepare. Thus, since it is only necessary to provide a temporary fixing member such as the spacer ring 8 or the sleeve 9, temporary fixing can be performed with a simple configuration.

  Further, according to the first embodiment, the plurality of anchor portions 5a have a shape in which the outside is bent convexly, and the spacer ring 8 or the sleeve 9 is elastically deformed inside the plurality of anchor portions 5a. Only the convex portion 5 a-1 is in contact with the stopper rib 2 a at the temporary insertion position where it is in contact with the inner wall of the locking hole 7 and restricts the movement of the clip 5 in the insertion direction. By doing in this way, the contact area of the anchor part 5a with respect to the inner wall of the locking hole 7 can be minimized, and the clip 5 at the temporary fixing insertion position can be easily pulled out from the locking hole 7.

  Furthermore, according to the first embodiment, since the ring-shaped spacer ring 8 in which the through-hole 8a through which the clip 5 is passed is used, it is only necessary to provide a temporary fixing member with a simple structure. Can be temporarily fixed.

  Further, according to the first embodiment, since the sleeve 9 including the cylindrical portion 9b through which the clip 5 is passed and the flange portion 9a projecting outward from the peripheral edge of the opening of the cylindrical portion 9b is used, a temporary structure with a simple structure is used. Since it is only necessary to provide a stopping member, temporary fixing can be performed with a simple configuration.

  In the present invention, any component of the embodiment can be modified or any component of the embodiment can be omitted within the scope of the invention.

  Since the temporary fixing structure between the members according to the present invention can be temporarily fixed with a simple configuration, it is suitable for temporary fixing between a bezel and a display body in a ceiling-suspended display in a vehicle.
