[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a reversible material fixture that can be used on both the front and back sides as necessary.
[0002]
[Prior art]
Many fixing tools for fixing various panel materials to a predetermined fixed body have been provided so far. In this case, the front and back surfaces of the panel material to be fixed are usually fixed. Therefore, the fixing device itself is not required to have such a complicated function.
[0003]
[Problems to be solved by the invention]
However, for example, when the decorative board fixed to the front face side of the drawer is reversible with different designs on the front and back, in order to use the front and back each time, Depending on the mode of use, dedicated fixtures will be required for both the front and back surfaces, but if a dedicated fixture is used, unnecessary fixtures will protrude on the usage surface, so structurally Needless to say, however, it is not preferable in terms of appearance.
[0004]
Therefore, it is necessary to use a fixture that can be shared between the front and back surfaces. As a general method, when using the front surface of the decorative board, a screwing method is used on the back surface side of the decorative board. If you use the back side of the decorative plate, the clip attached to the back side is now attached to the front side. It is conceivable to attach the clip to the mounting hole, but if such a method is adopted, the complicated replacement work of the clip will be forced. I hate being.
[0005]
[Means for Solving the Problems]
The present invention has been developed in view of such circumstances, and is a fixture that uses a reversible material separately on the front and back sides and fixes it to a fixed body, and is an escutcheon that is attached to a mounting hole formed in the reversible material. And an operation lever that is supported at both ends so that it can be moved up and down in the escutcheon, and a position in which the operation lever is pushed into one and the other in the escutcheon. When the operating lever is pushed into one or the other, the pressing operation part that is positioned below the operating lever is received by a locking member provided on the fixed body side. The structure which fixes a reversible material to a to-be-fixed body was adopted.
[0006]
Therefore, in the present invention, even when the front surface of the reversible material is fixed as the front side, or conversely, when the back surface is fixed as the front side, the operation lever supported in the escutcheon is simply pushed in a predetermined direction. Therefore, since the corresponding pressing operation part of the operation lever is received by the locking member provided on the fixed body side, a dedicated fixing tool is used for both the front surface and the back surface, or a common fixing tool is used. Even without replacement, it is possible to use the reversible material separately on the front and back sides and fix it to the fixed body immediately.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on a preferred embodiment shown in the drawings. A fixing device according to the embodiment is used for fixing a reversible cover of a storage chamber for storing a spare tire on the side of a vehicle luggage compartment. As shown in FIG. 1, the basic structure is a rectangular upper frame edge 1A constituting the escutcheon 1, a slightly larger rectangular lower frame edge 1B, and trapezoidal shapes at both upper and lower ends. One operating lever 2 that is supported so as to move up and down in the upper frame edge 1A and the lower frame edge 1B by projecting the pressing operation portions 2a and 2b to the front side (arrow FR side, specifically described later). And a positioning member 3 for selectively positioning the operation lever 2 at a position where the operation lever 2 is pushed into one of the upper frame edge 1A and the lower frame edge 1B and a position where the operation lever 2 is pushed into the other.
[0008]
The upper frame edge 1A has a trapezoidal through-hole 4 through which the operation lever 2 is inserted at the center, and boss-shaped screw holes 5 are formed at the four corners of the inner surface. A through-hole 6 with a stopper wall 7 through which the operation lever 2 is inserted is formed at the center, and through-holes 8 for screws 18 are formed at the four corners corresponding to the screw holes 5, and each through-hole closer to one side is formed. A locking portion 9 having a locking claw 9a for locking and fixing the edge of the base plate 3a of the positioning member 3 is formed on both outer portions of the peripheral edge of the positioning member 3, and the operating lever 2 is formed on the inner surface of the body. The projections 10 that are paired in the vertical direction are formed in two steps.
[0009]
The positioning member 3 has a through hole 11 of a screw 18 at both ends of the base plate 3a spanned between the insertion holes 8 on the one side and a stopper wall 12 on the upper surface side of the inner central edge. As shown in FIG. 2, a pair of elastic arms 13 having a J-shape that elastically contacts the projections 10 of the operation lever 2 are formed on the side of the stopper wall 12. Accordingly, when the operating lever 2 moves up and down, the pair of protrusions 10 get over the pair of elastic arms 13 in two stages and are positioned and held in response to this.
[0010]
A guide 14 is provided between the pair of elastic arms 13 so as to extend in a convex shape over the entire length of the elastic arm 13 along the movement direction of the operation lever 2, so that the operation lever 2 is moved or on one or the other side. In the pushed-in state, a configuration is adopted that prevents the operation lever 2 from tilting, rattling or generating vibration noise. For this reason, the pair of protrusions 10 are located on the outer side of the operation lever 2, but the guide 14 faces the central flat surface sandwiched between the protrusions 10, and thus interferes with the protrusions 10. And stable movement of the operating lever 2 can be ensured.
[0011]
In addition, the presence of the guide 14 does not give an excessive bending deformation force from the operation lever 2 to the elastic arm 13, so that the elastic arm 13 can be effectively prevented from being broken and also in the assembly process of the positioning member 3. In addition, it is possible to prevent breakage or entanglement due to interference with other parts. In addition, as shown in the figure, the guide 14 is divided into left and right by the dividing groove 15 so as to have a relatively small surface area, so that the so-called shrinkage can be prevented when the injection molding is solidified. The guide surface is molded with high accuracy, and the guide property with respect to the operation lever 2 is further improved.
[0012]
Further, a configuration is adopted in which a concave groove 16 is formed on the side opposite to the stopper wall 12 of the positioning member 3 and the concave groove 16 is engaged with a convex wall 17 that defines the periphery of the through hole 6 of the lower frame edge 1B. As a result, the positional relationship between the guide 14 and the elastic arm 13 in the vertical direction is ensured with high accuracy near the operation lever 2 and the relationship between the two is also good.
[0013]
Further, the fixed state of the positioning member 3 is determined not by the relationship between the concave groove 16 and the convex wall 17 but by the relationship between the periphery of the through-holes 11 at the both ends and the locking portion 9, so that the guide 14 The elastic arm 13 is elastically supported by the base plate 3a of the positioning member 3, so that the operation feeling of the operation lever 2 is also improved. When the positioning member 3 is fixed, the edge 16a of the groove 16 is positioned with a slight gap between the edge 16a and the stopper wall 7 of the lower frame edge 1B. Itself is left floating in the air.
[0014]
On the other hand, as shown in FIG. 3, the reversible cover 21 has a board structure in which a carpet mat similar to the vehicle body floor is laid on the front surface 21a side, and the back surface 21b side is covered with a resin surface. A hook HK that engages with the front cover member FC is provided on the front side (arrow FR side) 21 and both sides thereof are supported by the side floor trim ST as described later. Further, two left and right mounting holes 23 for mounting the escutcheon 1 are formed on the rear end side of the reversible cover 21 with the handle 22 interposed therebetween. Two left and right brackets 31 to be welded to the rear side of a vehicle body panel (not shown) are provided at positions that do not interfere with the spare tire, and as shown in FIG. A fastening hole 32 is provided for fastening the 33A and 33B by obtaining their elastic deformation.
[0015]
As shown in FIG. 5, each of the rubber locking members 33A and 33B includes a rectangular enlarged flange portion 34 and a similar leg portion 35, and the enlarged flange portion 34 to the inside of the leg portion 35 are formed. A penetrating insertion hole 36 into which the pressing operation portions 2a and 2b of the operation lever 2 are inserted is formed, and an elastic tongue piece 37 projects from the inner surface of the insertion hole 36 on the vehicle front side (arrow FR side). It is the composition to do. The elastic tongue piece 37 has both sides separated from the leg portion 35 and is easily bent. Therefore, anyone can easily operate the elastic tongue piece by reducing the operation force of the operation lever 2 and the elastic tongue piece. By increasing the protrusion length of 37, the certainty of operability can be guaranteed.
[0016]
Therefore, under such a configuration, the operating lever 2 is inserted into the through holes 4 and 6 of the upper frame edge 1A and the lower frame edge 1B constituting the escutcheon 1, and at the same time, the positioning member 3 on the lower frame edge 1B side. As shown in FIG. 6, the hole edge of each mounting hole 23 of the reversible cover 21 is held by the upper frame edge 1A and the lower frame edge 1B from the front and back sides, and each insertion hole 8 of the lower frame edge 1B is held. When the screws 18 are screwed into the corresponding screw holes 5 of the upper frame edge 1A, the fixing tools are respectively attached to the left and right attachment holes 23 of the reversible cover 21. At this time, a gap CL is defined between the upper surface of the positioning member 3 on the upper frame edge 1 </ b> A side and the lower edge of the through hole 4.
[0017]
Therefore, when the reversible cover 21 is fixed to the spare tire storage chamber 41, when the front surface 21a is fixed to the front side, the reversible cover 21 is placed on the periphery of the storage chamber 41 as it is until now. When the pressing operation portion 2a on the upper side of each operation lever 2 protruding upward is pressed downward until it collides with the stopper wall 12 that is floating in the air of the positioning member 3, as shown in FIGS. The protrusion 10 on the operation lever 2 side moves downward while getting over the elastic arm 13 of the positioning member 3, and the lower pressing operation portion 2b is received in the insertion holes 36 of the locking members 33A and 33B. Since the elastic tongue piece 37 is bent and passes further downward, this allows the reversible cover 21 to be laid with a carpet mat while receiving an appropriate operational pressure directly with a finger. So that the fixed and 21a as the front side.
[0018]
When the operation lever 2 is moved downward, the pair of protrusions 10 get over the elastic arm 13 of the positioning member 3 and are positioned with a sense of moderation. There is nothing to do. Further, since the pressing operation portion 2b (2a) has a trapezoidal shape and presses the elastic tongue piece 37 on the short side of the trapezoid, the elastic tongue piece 37 is easily bent.
[0019]
At this time, as shown in FIG. 7, both side edges of the reversible cover 21 are supported by the step SS of the side floor trim ST. Further, inadvertent movement of the reversible cover 21 toward the front side of the vehicle (arrow FR side) can be prevented by the engagement between the pressing operation portion 2b and the elastic tongue 37, but for further excessive movement, This can be prevented by engagement with the bracket 31.
[0020]
On the contrary, when fixing the back surface 21b of the reversible cover 21 covered with the resin surface as the front side, if the handle 22 is grasped and the rear end portion of the reversible cover 21 is forcibly pulled upward, the left and right operation levers 2 The pressing operation portion 2b located on the lower side is pulled out from the insertion hole 36 of the locking members 33A and 33B while bending the elastic tongues 37 of the locking members 33A and 33B, and the reversible cover 21 itself is fixed. This time, the reverse side 21b is turned upside down, and the reversible cover 21 is again placed on the periphery of the storage chamber 41 and positioned above each operation lever 2 protruding upward. When the pressing operation portion 2b is pressed downward until it collides with the stopper wall 7 of the lower frame edge 1B, as shown in FIGS. Let me accept pushing operation section 2a which was to location to the locking member 33A · 33B insertion hole 36 of reversible cover 21 is to be fixed to the rear surface 21b which is covered with a resin surface as a front side.
[0021]
In this case, it goes without saying that the protrusion 10 on the operation lever 2 side moves over the elastic arm 13 of the positioning member 3 with a sense of moderation and is positioned, but due to the presence of the gap CL described above, the protrusion 10 At the time of getting over, the base plate 3a itself of the positioning member 3 is bent, and when the getting-over is completed, the base plate 3a returns to the original position, so that a feel different from the surface 21a side can be obtained. At this time, since the concave groove 16 of the positioning member 3 collides with the convex wall 17 and emits a sound, a different feel can be obtained even by hearing. In addition, unlike the case of the surface 21a, the pressing operation portion 2b directly collides with the stopper wall 7 of the lower frame edge 1B having a different support rigidity from the stopper wall 12 of the positioning member 3. When the front surface 21a is used and the back surface 21b is used, the operation feeling and sound quality of the operation lever 2 are different, and it is possible to check which surface is currently used by the operation feeling and sound quality. .
[0022]
However, in this fixed state, unlike the case where the surface 21a of the reversible cover 21 is the front side, the pressing operation portion of the operating lever 2 as shown in FIGS. 2a will stop immediately before passing through the elastic tongues 37 of the locking members 33A and 33B. In this case, the use on the back surface 21b side is rather unusual. So it is not a problem.
[0023]
Therefore, in such use on the back surface 21b side, the back surface 21b is completely covered with the resin surface. Even if it is placed, there is no concern that the surface 21a on which the carpet mat is laid will be soiled. Thereafter, when it is desired to use the surface 21a as the front side, the same operation as described above may be repeated.
[0024]
Note that the locking members 33A and 33B may be set so that the positions of the elastic tongue pieces 37 are different from each other on the left and right, as indicated by phantom lines in FIG. In this case, since the height of the elastic tongue 37 is different in the vertical direction between the left and right engaging members 33A and 33B, on the left side, as shown in FIG. 7, between the pressing operation portion 2b and the elastic tongue 37. In the right side, as shown in FIG. 8, there is a small interval L2 between the pressing operation portion 2b and the elastic tongue 37, and the contact timing between the pressing operation portion 2b and the elastic tongue 37 is as follows. Differently on the left and right, the operating force when the reversible cover 21 is pulled up can be made relatively small.
[0025]
【The invention's effect】
As described above, according to the present invention, the operation lever that is supported in the escutcheon is simply adopted regardless of whether the surface of the reversible material is fixed as the front side or the reverse side is fixed as the front side. Just by pushing in the predetermined direction, the corresponding pressing operation part of the operating lever can be received by the locking member provided on the fixed body side, so a dedicated fixing tool can be used on both the front and back surfaces or a shared Even without changing the fixing tool, the reversible material can be used separately on the front and back sides, and can be immediately fixed to the fixed body.
