TECHNICAL FIELD OF THE INVENTION
The present invention relates to an opening / closing lid mounting structure.
[0002]
[Prior art]
An opening formed in an accessory such as an instrument panel of an automobile is provided with a lid that can be opened and closed. In this type of lid, the lower edge of the lid is engaged with the lower edge of the opening from above, so that the entire lid can be rotated around the lower edge. A spring member having a downward elastic force is provided at an upper portion in the opening, and a rail member elastically contacting the spring member is provided at the lid. A recess is formed at the end on the closed side of the rail member, and the open position of the lid is maintained by engaging a spring member in the recess. The closed position of the lid is maintained by elastic contact between the spring member and the rail member.
[0003]
[Problems to be solved by the invention]
However, in such a conventional technique, since the concave portion for maintaining the open position of the lid is formed at the closed end of the rail member, when the lid is attached to the opening, first of all, Then, the recess is engaged with the spring member, the lid is lifted in this state, and the vicinity of the lower end of the lid is engaged with the lower edge of the opening from above. Therefore, since the spring member must be pushed upward by the lid, a large force is required for the mounting operation, which is disadvantageous in terms of workability. If an operation requiring a large force is mistaken, an excessive force is applied to the lid and the spring member, and there is a possibility that a part of the lid and the spring member may be damaged. Furthermore, since the lower end of the lid is engaged with the lower edge of the opening while the spring member is being pushed up by the lid, the part to be engaged is difficult for the operator to see. It becomes. In addition, the work is a double action of pushing up the spring member with the lid and engaging the lower end of the lid with the lower edge of the opening, which is not preferable in terms of working efficiency.
[0004]
The present invention focuses on such a conventional technique, and provides an opening / closing lid mounting structure that does not require a large force for mounting the lid and that can be mounted in a single action.
[0005]
[Means for Solving the Problems]
The invention according to claim 1, wherein the lower edge of the lid is engaged with the lower edge of the opening formed in the attached component from above, and the lid is rotatable about the lower end as a center. A spring member having a downward elastic force is provided in an upper portion of the inside, a rail member elastically contacting the spring member is formed on the lid, and the rail member is engaged with the spring member to maintain a closed position of the lid. A mating portion is formed, and a protrusion protruding laterally is formed on the lid. On the other hand, when the lid is attached to the opening, the protrusion can move over when the lid is turned to the closed side, and the lid can be moved to the open side. When pivots, a stopper is formed on the attached part so that the projection contacts the opening position of the lid, and the tip on the closing side of the rail member, until the projection climbs over the stopper when the lid is attached, Does not elastically contact with spring members It characterized in that in the location.
[0006]
According to the first aspect of the present invention, the engagement portion of the rail member with respect to the spring member maintains the “closed position” of the lid, and does not maintain the open position unlike the related art. The engagement part is located on the opening side. Therefore, when the lid is first attached to the opening, there is no need to previously engage the engaging portion with the spring member. That is, conventionally, since the engaging portion of the rail member was at the end on the closing side, the next operation could not be performed unless the engaging portion was previously engaged with the spring member and pushed up. However, in the present invention, the function of positioning the opening position is left to the newly provided stopper, and the engaging portion is not formed on the closed side of the rail member for regulating the opening position. There is no need to engage the spring member and push it up. Therefore, according to the present invention, after the lower end of the lid is engaged with the lower edge of the opening from above, the lid is simply closed along the normal opening / closing operation, so that the protruding portion gets over the stopper and the spring member Automatically engages with the engaging portion of the rail member, so that the work is essentially a single action in which the lower end of the lid is engaged with the lower edge of the opening from above. No big power is needed. Furthermore, since the operation of engaging the lower end of the lid near the lower edge of the opening from above is not performed while pushing up the spring member, the worker should be in a comfortable posture and make the lid easy to see. It is possible to reliably work while visually confirming the engagement location. Further, since the rail member does not elastically contact the spring member until the projection is over the stopper and the lid is in the mounted state, no further force is required when mounting the lid, and workability is improved.
[0007]
According to the second aspect of the invention, the projection has a cylindrical or columnar shape.
[0008]
According to the second aspect of the present invention, since the projection has a cylindrical or columnar shape, it can easily get over the stopper during mounting.
[0009]
According to the third aspect of the present invention, the contact portion of the stopper with respect to the projection is formed in an inclined state with the lid opening side end portion facing upward.
[0010]
According to the third aspect of the present invention, the contact portion of the stopper with respect to the projection is formed in an inclined state with the open side facing upward, so that when the lid is forcibly opened, the projection engages the stopper. It is possible to prevent the protrusion and the stopper from being broken by getting over and breaking.
[0013]
According to the fourth aspect of the present invention, a guide portion inclined downward from the rail member is formed at the front end on the closed side of the rail member.
[0014]
According to the fourth aspect of the present invention, a downwardly inclined guide portion is formed at the tip of the rail member, and even when the lid is slightly floated when the lid is mounted, the guide portion allows the spring to be formed. Since the member can be guided to the upper surface of the rail member, the mounting workability of the lid is improved.
[0015]
According to the fifth aspect of the present invention, the guide and the projection are connected by a flange.
[0016]
According to the fifth aspect of the present invention, since the guide and the protrusion are connected by the flange, the rigidity of the protrusion is improved, and the breakage resistance of the protrusion is improved.
[0017]
In the invention according to claim 6 , a box for storing small items is formed on the back surface of the lid, and a rail member and a protrusion are formed on the side surface of the box.
[0018]
According to the invention described in claim 6 , small items can be put in the box formed on the back surface of the lid. In addition, by using the side surface of the box, the formation of the rail member and the protrusion is facilitated.
[0019]
【The invention's effect】
According to the present invention, after the lower end of the lid is engaged with the lower edge of the opening from above, the lid can be closed simply along the normal opening / closing operation, so that the projection can get over the stopper and the spring member can be moved. Since the engagement is automatically performed with the engagement portion of the rail member, the operation is substantially performed by a single action, and a large force is not required. In addition, since the work of engaging the lower end portion of the lid near the lower edge of the opening from above is not performed while pushing up the spring member, the worker should have a comfortable posture and make the lid easy to see, Work can be performed reliably while visually confirming the engagement location. Further, since the rail member does not elastically contact the spring member until the projection is over the stopper and the lid is in the mounted state, no further force is required when mounting the lid, and workability is improved.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS. The direction A in FIG. 1 is the front side (closed side) and the direction B is the rear side (opened side).
[0021]
Reference numeral 1 denotes an instrument panel as a “part to be mounted”, which is a synthetic resin product fixed to the front of the cabin of an automobile. The instrument panel 1 has a rectangular opening 2 formed therein. A fuse box (not shown) is installed inside the opening 2, and replacement of the fuse can be performed through the opening 2.
[0022]
Further, since the opening 2 is closed by a lid 3 which can also be opened and closed, it also has a structure for that purpose. That is, the lower edge 4 of the opening 2 is formed in a crank shape so that the lid 3 can be easily placed thereon. A forward-facing wall 5 is formed on the left edge, and a stopper 6 is formed on the wall 5 toward the right. The stopper 6 has a plate shape, and the rear end contact portion 7 is in an inclined state with the rear end raised. Further, a boss 8 is formed on the inner surface of the instrument panel 1 corresponding to a substantially upper portion of the wall 5, and a spring member 9 having a downward elastic force is fixed to a front end thereof. .
[0023]
The lid 3 has a square shape slightly larger than the opening 2. A handle 10 is formed on an upper portion of the lid 3. A box 11 having a size corresponding to the opening 2 is formed on the front surface of the lid 3. The bottom of the box 11 is smaller in front and rear dimensions than the top, and a hinge groove 13 for engaging the lower edge 4 of the opening 2 from above is formed near the lower end 12 of the lid 3 on the bottom. .
[0024]
A substantially arc-shaped rail member 14 centering on the hinge groove 13 is formed at the upper end of the left side surface portion of the box 11. In the middle of the rail member 14, a concave portion 15 is formed as an "engaging portion". From the front end 14a of the rail member 14, a guide portion 16 is formed continuously in a state where the front side of the rail member 14 is inclined downward. A cylindrical projection 18 protrudes from the left side surface 17 of the box 11 below the rail member 14, and the projection 18 and the front end of the guide 16 are connected by a flange 19. Are linked. The rear end of the flange 19 is connected to the upper and lower central positions of the cylindrical projection 18. Accordingly, the lower half of the projection 18 protrudes below the flange 19. The distance between the upper end of the lower edge 4 of the opening 2 and the upper end of the contact portion 7 of the stopper 6 is larger than the distance between the bottom of the hinge groove 13 of the lid 3 and the lower end of the projection 18. ing.
[0025]
Next, a normal use state in which the lid 3 is attached to the opening 2 and a procedure for attaching the lid 3 to the opening 2 first will be described. The positional relationship and dimensional relationship of each component described above will be described in the following description.
[0026]
First, a use state after the lid 3 is first attached will be described with reference to FIG. FIG. 2 shows a state in which the lid 3 is already attached to the opening 2. The solid line indicates a closed state, and the imaginary line (two-dot chain line) indicates an open state. In the closed state, the spring member 9 is engaged with the concave portion 15 of the rail member 14, and the closed state of the lid 3 is maintained by the engagement force. The lower end of the spring member 9 and the rail member 14 are wrapped by a small dimension d, and the spring force of the spring member 9 due to this dimension d is applied to the rail member 14 at portions other than the recess 15. Working.
[0027]
In the open state, the protrusion 18 formed on the left side surface portion 17 of the box 11 comes into contact with the contact portion 7 of the stopper 6. Therefore, the contact between the protrusion 18 and the contact portion 7 causes the opening of the lid 3. Position is regulated. Each time the lid 3 is opened, the protrusion 18 hits the contact portion 7 of the stopper 6, but the protrusion 18 is easily broken because the flange 19 is connected to the flange 19 extending from the front end of the guide portion 16. Never. Furthermore, since the contact portion 7 of the stopper 6 is inclined such that the rear end thereof is lifted upward, a person who does not know the correct operation method can temporarily move the lid 3 further in the opening direction than the regular opening position. Even if it is attempted to open with a strong force, the protrusion 18 can be prevented from being damaged simply by slipping over the contact portion 7 of the stopper 6 and coming off.
[0028]
Next, a procedure for attaching the lid 3 to the opening 2 first will be described with reference to FIG. First, the hinge groove 13 near the lower end portion 12 of the lid 3 is placed on and engaged with the lower edge portion 4 of the opening 2. At this time, since the upper part of the lid 3 is in a free state, the operator can easily engage the lid 3 so that the relation between the hinge groove 13 and the lower edge part 4 can be easily seen. It is possible to work reliably while visually confirming.
[0029]
After the hinge groove 13 is engaged with the lower edge portion 4, the lid 3 is rotated forward about the hinge groove 13. When the lid 3 is rotated to the front side, the projection 18 formed on the left side surface 17 of the box 11 hits the rear end of the contact portion 7 of the stopper 6. Since a flange 19 is formed on the front side from the upper and lower central portions of the projection 18, the rear end of the contact portion 7 contacts the lower half of the projection 18. Therefore, by pushing the lid 3 forward, the projection 18 can easily pass over the rear end of the contact portion 7.
[0030]
When the protruding portion 18 gets over the rear end of the contact portion 7, the lid 3 is attached to the opening 2 (that is, the lid 3 is in the open position in the normal use state of the lid 3 described above). Becomes). Only in this state, the guide portion 16 formed from the front end 14a of the rail member 14 comes into contact with the lower end of the spring member 9. Until then, the spring force of the spring member 9 acts on the lid 3. do not do. Therefore, since a large force is not required for mounting the lid 3, there is no danger that the lid 3 or a part of the opening 2 may be damaged due to excessive force as in the related art. In addition, since the guide portion 16 inclined downward from the front end 14 a of the rail member 14 is formed, even when the lid 3 is slightly floated when the lid 3 is mounted, the guide portion 16 allows the spring to be formed by the guide portion 16. The member 9 can be guided to the position of the front end 14a of the rail member 14, and a reliable mounting state can be obtained.
[0031]
Then, as described above, after the hinge groove 13 of the lid 3 is engaged with the lower edge portion 4 of the opening 2, the lid 3 is simply closed in accordance with a normal opening / closing operation, and the protrusion 18 causes the stopper 6 to move. Since the rider gets over the vehicle, the work is substantially completed in a single action, and the efficiency of the work of attaching the lid 3 is improved. As described above, the single action is sufficient because the recess 15 of the rail member 14 with respect to the spring member 9 maintains the "closed position" of the lid 3, and maintains the open position as in the related art. Therefore, the concave portion 15 in the rail member 14 does not need to be formed at the end on the closed side (the tip when mounting). Therefore, when the lid 3 is first attached to the opening 2, it is not necessary to previously engage the recess 15 with the spring member 9. Therefore, the operation of engaging the hinge groove 13 of the lid 3 with the lower edge portion 4 of the opening 2 from above does not need to be performed while pushing up the spring member 9, so that the operation is substantially a single action operation, and does not require a large force. .
[0032]
As described above, the structure in this embodiment has been described as an example, but the present invention is not limited to this embodiment, and the following changes may be made.
[0033]
Although the example in which the rail member 14 and the protrusions 18 are formed only on the left side of the lid 3 has been described, they may be formed on both left and right sides.
[0034]
The spring force of the spring member 9 is not applied to the rail member 14 until the projection 18 climbs over the stopper 6 and the lid 3 is mounted. Alternatively, the spring member 9 may elastically contact the rail member 14. Even in such a case, only a small closing force is required when the lid 3 is attached, and the required force is overwhelmingly smaller as compared with the conventional operation in which the spring member 9 is lifted directly above. Does not lead to a decline in sex.
[0035]
Since the accessory box 11 is formed in the lid 3, the rail member 14 and the protrusion 18 can be easily formed by using the left side surface 17 of the box 11. However, depending on the structure of the opening 2, Instead of forming the box 11, the rail member 14, the protrusion 18, and the like may be formed directly from the lid 3.
[0036]
The projection 18 has a cylindrical shape so that it can easily get over the stopper 6, but may have a cylindrical shape.
[0037]
The recess 15 is formed in the middle of the rail member 14 as an “engaging portion” for the spring member 9. If the “engaging portion” is engaged with the spring member 9, the closed state of the lid 3 can be maintained. For good reasons, a convex portion may be used.
[0038]
Although the rail member 14 has an arc shape centered on the pivot point of the lid 3, the shape is not necessarily limited to the arc shape, and may be a curved shape other than an arc as long as the elastic contact with the spring member 9 is obtained.
[0039]
The rigidity of the projection 18 is increased by connecting the front end of the guide section 16 and the projection 18 with a flange 19. The rigidity may be further increased.
