Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid display for closing openings of various underground structures, and more particularly to a lid display for displaying information for managing various underground structures on the lid surface. It is a thing.

Conventionally, as a display tool of this type, a bolt is planted on the lower surface of a display plate that displays information such as numbers, letters, and symbols, and the bolt is inserted into a mounting hole of the lid and the rear surface of the lid is inserted. Some of them are fixed to the lid by being screwed with a nut.

Further, in Japanese Unexamined Patent Publication No. 2000-273889, a leg portion consisting of four divided pieces is projected on the lower surface of a display panel indicating information such as numbers, characters and symbols, and a lower portion of the leg portion. A display member provided with a bulge is disclosed. The display member is fixed to the lid by inserting the leg portion into the hole provided in the lid and engaging the upper surface of the bulging portion with the lower edge portion of the hole of the lid.

However, the former display device which is fixed with bolts and nuts has a problem that screwing the bolts and nuts is troublesome and the fixing work is complicated. Also, when the lid vibrates due to passage of the vehicle, the nut may loosen and come off the bolt, or the looseness may cause rattling of the display tool, and the display plate may be broken from the bolt due to the impact when the vehicle is passing. However, there is a problem that the display device cannot be securely and stably fixed to the lid.

The upper surface of the bulging part of the leg is simply locked by being fixed to the hole edge of the lower surface of the lid, and in the same way as the former case, in addition to the vibration of the lid due to the passage of the vehicle, the vehicle etc. on the display board There is a problem that the engagement between the bulging portion of the leg portion and the hole edge portion is likely to be disengaged due to the load when the vehicle directly travels. Further, since the dimension between the lower surface of the display panel and the upper surface of the bulging portion is specified, the thickness of the lid that can fix the display member is limited. For example, if the thickness of the lid varies, play may occur. There is a problem that it is loose (when it is thin) or cannot be locked due to insufficient dimensions (when it is thick), and it is difficult to fix it to the lid in a reliable and stable state.

The present invention has been made to solve the above-mentioned problems, and can be easily attached and detached or fixed to a lid in a reliable and stable state to prevent the detachment or damage at the time of fixing, and even if the thickness of the lid varies. Even if there is, it is an object of the present invention to provide a lid display device that can cope with the variation by absorbing it.

When the hole 2k passes through the locking portion 2c 'which can be projected outward, the lower surface of the plate-like body 2j is locked to the locking portion 2c' by repulsing and returning to the outside, and at the same time,
The coil spring 3a fixes the display main body 2 to the lid 4 against the repulsive elastic force between the coil spring 3a and the back surface 4b of the lid 4 by using the upper surface of the plate-shaped body 2j as the locking portion 2c.

Thus, in the display tool 1 shown in FIGS. 1 and 4 to 8, the engaging portion 2c '(FIG. 1) provided on the plate-like body 2j, which is the engaging portion 2c, and the fitting. The insertion hole 2k (FIG. 4) and the convex portion 2l (FIG. 5) engage with the concave groove 2i (FIG. 1, FIG. 4 and FIG. 5) in the leg portion 2b in a concavo-convex manner, or the plate-like body 2j has its lower surface on the leg It is supported by a fastener 2n externally mounted on the portion 2b (FIGS. 6 and 7), or the plate-like body 2j is locked at its lower surface by a locking portion 2c 'which is projected to the leg portion 2b itself (see FIG. 8) In addition, since the coil spring 3a is constantly pushed down against the repulsive force, the fixed state is not released when any external force such as the vibration of the lid 4 is applied. Further, the plate-like body 2j in the fixed state causes the coil spring 3a to be compressed and deformed, the plate-like body 2j is rotated, or the fastener 2n is removed, or the leg portion 2b.
The plate-like body 2j can be automatically pulled out from the leg portion 2b against the repulsive force of the coil spring 3a only by temporarily reducing the diameter of the lower end of the coil against its repulsive elasticity and releasing the fixing. it can.

In each of the above embodiments, the leg portion 2b is used.
Is formed into a triangular prism or a column, or a leg piece 2d divided along the lengthwise direction, and the outer shape of the plate-like body 2j is formed into a circular shape. Is an example, and its design can be freely changed within the scope intended by the present invention, including its locking and engaging methods, and the coil spring 3a used as the elastic body 3 is replaced by a leaf spring or the like described later. You can change it. Further, in the embodiment shown in FIGS. 6 and 7, a split pin or a general-purpose nut is used as the fastener 2n forming the retaining portion of the plate-shaped body 2j.
Is not limited to the above, and may be any as long as it is detachably mounted near the lower end of the leg portion 2b and protrudes outward from the surface of the leg portion 2b. In addition, in the embodiment of FIG. 8 described above, a pin or the like is detachably inserted from below the leg portion 2b into a gap at the center thereof, and each leg piece 2d is pushed outward to expand the plate-shaped body 2j. The locking may be made more reliable, the number of leg pieces 2d may be increased or decreased in consideration of the mountability of the plate-shaped body 2j, or the plate-shaped body 2j may be firmly fitted to the leg portion 2b.
The legs 2b may be solid or hollow rod made of a flexible material.

Next, an embodiment in which the locking portion 2c is formed by circumferentially projecting the lower portion of the leg portion 2b itself will be described.
In the case of FIG. 9, as the elastic body 3, as shown in FIG. 10 (e), the inner diameter of the lower end portion 3b is formed to be smaller than the outer contour of the locking portion 2c, and the elastic body 3 is formed to be slightly larger than the diameter of the leg portion 2b.
Also, a conical coil spring 3 that expands on the upper end 3c side thereof
a is used. In this case, the leg portion 2 of the display tool body 2
The two leg pieces 2d forming b are fitted into the mounting holes 4a of the lid 4, and are fitted into the leg pieces 2d protruding toward the back surface 4b of the lid 4 from below with the expanded side of the coil spring 3a facing upward. At this time, when the lower end 3b of the coil spring 3a is in contact with the back surface 4b and the lower end 3b is compressed and pushed along the inclined surface 2e on the outer side of the lower end of the leg 2d, each leg 2
The lower ends of d are respectively reduced inward, and when the lower end 3b reaches the engaging portion 2c, the coil spring 3a is repulsed and returns to the outside so that the coil spring 3a is provided between the engaging portion 2c and the back surface 4b of the lid 4. Is fitted against the impact resilience of the display device main body 2 with the lid 4
Fixed to.

The case of FIG. 11 is also similar to the case of FIG. 9 described above, except that the leg portion 2b is divided into four leg pieces 2d, but is different from the above two leg pieces 2d. Since the locking portions 2c that lock the lower end portion 3b of the coil spring 3a are dispersed on the circumference, there is an advantage that the coil spring 3a can be fitted in a more stable state.

In the case of FIG. 12, as the elastic body 3, a leaf spring 3d having a plurality of plate pieces 3f projecting obliquely upward on the peripheral edge of the cylindrical portion 3e is used as shown in FIGS. Then, as shown in (a) and (b) of FIG.
The leg piece 2d protruding to the side is attached to the plate piece 3 of the leaf spring 3d from below.
When the cylindrical portion 3e is fitted with f facing upward, the plate piece 3f abuts the back surface 4b and the lower end of the cylindrical portion 3e is locked by the locking portion 2c. At this time, the leaf piece 3 of the leaf spring 3d
The f fixes the repulsion elasticity between the locking portion 2c and the back surface 4b of the lid 4 to fix the display body 2 to the lid 4. The leaf spring 3
The repulsive elastic force of d can be adjusted by changing the number of the plate pieces 3f protruding on the periphery thereof. For example, in the case of the leaf spring 3d shown in FIGS. Has been reduced to three.

In the case of FIG. 13, as the elastic body 3, as shown in (c) to (e) of the same figure, the four corners of the rectangular substrate 3i having the fitting insertion hole 3h in the central portion are bent obliquely upward. The leaf spring 3g is used to form the leaf piece 3f. As shown in (a) and (b) of FIG. 1, the leg piece 2d protruding toward the back surface 4b of the lid 4 is attached to the leg piece 3f of the leaf spring 3g from below. When the fitting insertion hole 3h is fitted in the state of facing upward, the plate piece 3f contacts the back surface 4b, and the peripheral edge of the fitting insertion hole 3h is locked by the locking portion 2c. At this time, the plate piece 3f of the plate spring 3g fixes the display body 2 to the lid 4 against the repulsive elasticity between the locking portion 2c and the back surface 4b of the lid 4.

In the case of FIG. 14, as the elastic body 3, a leaf spring 3j bent in a U shape as shown in FIGS. Notch recesses 3k having different opening directions are provided at opposite ends of the leaf spring 3j. That is, as shown in FIG. 4D, the notch recess 3k located in the lower member of the leaf spring 3j is opened downward to have a substantially inverted U shape, and the notch recess 3 located in the upper member.
k is opened upward and has a substantially U shape. In this case, as shown in (a) and (b) of FIG.
The leaf spring 3 is inserted so that the leg piece 2d protruding to the side is sandwiched from the side.
By fitting both notch recesses 3k of j, the upper member abuts the back surface 4b, and the peripheral edge of the notch recess 3k in the lower member is engaged with the engaging portion 2c. At this time, the leaf spring 3
The j fixes the display body 2 to the lid 4 against the repulsive elasticity between the locking portion 2c and the back surface 4b of the lid 4. The leaf spring 3
Instead of the cutout recess 3k of j, for example, as shown in (f) and (g) of the same drawing, the fitting insertion holes 3h may be formed in the facing surfaces of the leaf springs 3j that are bent in short, respectively. In this case, since the fitting insertion hole 3h is fitted from below the leg portion 2b, the upper member abuts the back surface 4b and the peripheral edge of the fitting insertion hole 3h in the lower member is locked to the locking portion 2c. .

In the case of FIG. 15, as the elastic body 3, a circular and slightly curved substrate 3i as shown in FIGS. A leaf spring 3o is provided in which a notch 3q having a cutout shape is provided, and standing pieces 3r along the edge of the substrate 3i are provided at appropriate intervals. As shown, the leg piece 2d protruding to the back surface 4b side of the lid 4 is fitted with the cutout portion 3q with the standing piece 3r of the leaf spring 3o facing upward, so that the standing piece 3r abuts on the back surface 4b. The cutout 3q at the center of the substrate 3i is engaged with the engaging portion 2c formed of a spherical portion at the peripheral edge of the cutout circle. At this time, the board 3i of the leaf spring 3o is engaged with the engaging portion 2c and the back surface 4 of the lid 4.
The display tool main body 2 is fixed to the lid 4 against the repulsive elasticity between the display main body 2 and b.

In the case of FIG. 16, the elastic body 3 is wound in a conical shape as shown in (c) to (f) of the figure, and the knobs 3t provided at both ends thereof are closed to wind it. A leaf spring 3s is used that is loose in its state and can widen its diameter and can be lowered in height (the state shown by the two-dot chain line in (e) and (f) in the figure). And, as shown in (b), the leg portion 2 protruding to the back surface 4b side of the lid 4
In b, the diameter is expanded by operating the knob 3t,
Further, the leaf spring 3s whose height is lowered is inserted and the operation is released, so that the leaf spring 3s fitted in the leg portion 2b is inserted.

Locks on the locking portion 2c and fixes the display main body 2 to the lid 4 against the repulsive elasticity between the lid 4 and the back surface 4b of the lid 4.

In the case of FIGS. 17A, 17B and 18, a conical coil spring 3a is used as the elastic body 3 as in the case of FIGS. 9 and 11, and the fixing method is also the same. However, the lower end portion 3b of the coil spring 3a is engaged with a concave groove as an engaging portion 2f provided in the locking portion 2c,
Further, the upper end portion 3c is provided on the back surface 4b of the lid 4 and the engaging portion 4 is provided.
It is surrounded and fixed by a convex strip as c. That is,
The lateral movement is restricted so that the coil spring 3a is reliably positioned between the locking portion 2c and the back surface 4b. In particular,
When the position of the upper end portion 3c of the coil spring 3a is restricted, the coil spring 3a is prevented from being deformed due to fatigue or the like (the diameter of the upper end portion 3c becomes large), and the repulsive elastic force can be maintained for a long period of time.

The ridge as the engaging portion 4c on the back surface 4b of the lid 4 is continuously formed in an annular shape in the cases of FIGS. 17A and 17B, and in the left half of FIG. Although the ring is divided so as to be discontinuous, the engaging portion 4c is not shown in FIG.
As shown in the right half portion, the back surface 4b of the lid 4 may be formed to be recessed, or as shown in FIG. It may be formed to have an outer shape.

The coil spring 3a is engaged with the engaging portion 4c forming an annular groove at b, and the coil spring 3a is reliably positioned between the engaging portion 2c and the back surface 4b.

Here, since the outer dimension of the locking portion 2c which is bulged and molded at the lower portion of the leg portion 2b is larger than the dimensions of the mounting hole 4a of the lid 4 and the lower end portion 3b of the coil spring 3a. The leg 2b needs to be made of a flexible material so that the leg 2b can be tightly fitted into the mounting hole 4a and the lower end 3b. However, when the leg 2b having the above-described shape has rigidity, FIG.
As shown in (a), the dimensions of the root of the leg 2b on the side of the display plate 2a and the outer portion of the locking portion 2c are set to be substantially compatible with the mounting hole 4a, and the trunk of the leg 2b is tapered. Or the dimensions of the outer portion of the locking portion 2c formed to have a large diameter and the root portion of the leg portion 2b formed to have a smaller diameter than that, as shown in FIGS. The two mounting holes 4a 'of the lid 4 are formed by connecting two holes 4a' each having a different size.
There is a method to do.

Further, in the case of FIGS. 17 to 19, both the upper end portion 3c and the lower end portion 3b of the coil spring 3a are engaged with the engaging portions 2f and 4c, respectively, which is preferable, but the upper end portion 3c is preferable. Only the engaging portion 4c may be engaged, or only the lower end portion 3b may be engaged with the engaging portion 2f. That is, the engaging portion 2 is attached to the engaging portion 2c of the leg portion 2b.
When the lid 4 is provided, the lid 4 does not have the engaging portion 4c, and when the lid 4 is provided with the engaging portion 4c, the engaging portion 2c does not have to have the engaging portion 2f.

Furthermore, a coil spring 3a as the elastic body 3
21 is an ordinary cylindrical coil spring 3a as shown in FIG.
Besides, it is also possible to use various different types of coil springs such as the coil spring 3a having the shape shown in FIG. 22 and the coiled spring 3a having the shape shown in FIG. 23. The repulsive elastic force is effectively and uniformly applied along the length direction of the leg portion 2b to fix the display tool main body 2.

Next, a description will be given of an embodiment in which the engaging portion 2c is formed in the lower portion of the leg portion 2b itself by being recessed from the outer surface thereof. In the case of FIG. 24, the leg portion 2b is formed as a corner-cutting triangular prism, and the engaging portions 2c recessed from the outer surface are provided at the lower three corner portions thereof, and the leg portion 2b has the same shape as the mounting hole of the lid 4. The coil spring 3a is engaged with the respective lower end portions 3b of the conical coil springs 3a which are fitted into the rear surface 4b of the leg portion 2b, and the lower end portions 3b of the conical coil springs 3a are engaged with each other. The display tool body 2 is fixed to the lid 4 by being fitted between the 2c and the back surface 4b of the lid 4 against the resilience. Here, the coil spring 3a is engaged with the locking portion 2c.
The axial section of the leg portion 2b surrounded by the lower end portion 3b is made circular to enhance the engaging property with the lower end portion 3b, but the axial section including the shape of the leg portion 2b itself is shown in FIG. Other than the polygon shown in), it can be freely set.

In the case of FIG. 25, the leg portion 2b is formed into a columnar shape, and in order to form the two leg pieces 2d on the lower end surface thereof, a one-character concave groove 2i is provided and a concave shape orthogonal to the concave groove 2i is formed. The engaging portion 2f is a leg piece 2 having a substantially L-shaped vertical cross section.
Each of the legs 2b has a lower end portion 3b linearly bent in the leg portion 2b as shown in FIGS. A cylindrical coil spring 3a having a V shape is fitted and inserted. That is,
The coil spring 3a is compressed and deformed from below the leg portion 2b which is inserted into the attachment hole 4a of the lid 4 and protrudes toward the back surface 4b, and the lower end portion 3b is attached to the lower end surface of the leg portion 2b. It is inserted in a certain one-letter groove 2i, and the groove 2i
When the coil spring 3a is rotated 90 degrees at the time of reaching the upper end, the lower end 3b is incorporated in the leg piece 2d.
, The coil spring 3a is fixed to the leg portion 2b, and at the same time, the display body 2 is fixed to the lid 4 against the repulsive elastic force between the engaging portion 2f and the back surface 4b. To do.

In each of the embodiments described above, the locking portion 2c
The repulsive elastic force of the elastic body 3 acting between the back surface 4b and the back surface 4b exerts an action of pushing down the display tool main body 2 with the back surface 4b as a repulsive surface and constantly pulling it downward, so that the lid 4, the display tool main body 2 and the elastic body 3 are provided. Are integrally connected and fixed. Further, the plate-like body 2j forming the engaging portion 2c is removed, the lower ends of the legs 2b are temporarily reduced in diameter against the repulsive elastic force, or the elastic body 3 itself is changed to the repulsive elastic force. The display body 2 is also detachably fixed to the lid 4 by temporarily deforming the elastic body 3 so that the elastic body 3 is detachable from the leg portion 2b.

[0053]

As described above in detail, in the display device of the present invention, the elastic body fitted to the leg portion of the display device main body protruding to the back surface side of the lid is provided between the engaging portion of the leg portion and the back surface of the lid. Since the main body of the display is fixed against the impact resilience, even if the lid vibrates due to the passage of vehicles, the vibration is absorbed without being vibrated or transmitted due to the elastic characteristic of the elastic body. Therefore, the display main body is not rattled or displaced with respect to the lid, so that the display main body is securely and stably fixed to the lid without being detached or damaged. Moreover, since the elastic body is fixed by the repulsive elastic force, it is possible to systematically use a lid having a different thickness rather than a lid having a slight variation in thickness. Further, since the elastic body detachably fixes the display device main body, when the display contents are changed after the display device main body is once fixed to the lid, or when the display device main body and the elastic body have a problem, etc. It can be easily replaced if necessary.

Further, in the display device of the present invention, the plate-like body for inserting the fitting insertion hole into the leg portion is mounted so as to project in the circumferential direction of the leg portion, and the locking portion is formed. The lower part of the leg is detachable at a position rotated by a predetermined angle about the leg, or the lower part of the leg is formed into a substantially triangular cross-section projecting from the body of the display device. The plate surface of the plate-shaped body having the similar insertion hole formed therein is provided with concave grooves that engage with the substantially triangular corners of the lower portion of the leg at the three edges of the insertion hole. Since the body is rotatable or fixed on the body of the leg, the leg of the display body can be easily inserted into the mounting hole of the lid with the plate removed, and the back of the lid Insert the plate into the leg by a simple operation of inserting the plate into the leg protruding to the side and rotating it by a predetermined angle to lock and engage with the lower part of the leg. The elastic member can be compressed and deformed between the rear surface of the plate-like body top surface and the lid, a good workability is secured and dismounting made quickly.

Further, in the display device of the present invention, the plate-like body for inserting the fitting insertion hole into the leg portion is locked by the fastener which is detachably mounted near the lower end portion of the leg portion, and An engaging portion is formed by being attached so as to project in the circumferential direction at the lower portion, or the plate-like body is detachably engaged with the lower portion of the leg portion itself that projects outward in the circumferential direction, and Since the locking part is formed by being mounted so as to project to the plate, the plate-shaped body is locked to the fastener installed on the lower part of the leg, or the fitting insertion hole of the plate-shaped body is strongly fitted to the leg. The elastic body inserted in the legs can be compressed and deformed between the top surface of the plate and the back surface of the lid by a simple operation to lock the legs to the outer lower part, which facilitates fixing and removal work. You can

Moreover, in the display device of the present invention in which the plate-like body is assembled to the leg portion to form the locking portion, the plate-like body is constantly pushed down against the repulsive force of the elastic body which is compressed and deformed. Therefore, even if any external force such as the vibration of the lid is applied during the fixing, the locking and engagement can be surely fixed without being released, and at the time of removal, the plate-like body is rotated to perform the locking and engagement. The plate-like body is automatically removed by simply releasing the fitting, removing the fasteners that are installed on the legs from the legs, or temporarily reducing the lower end of the legs to unlock the plate-like body. Can be pulled out from. Further, the shape and size of the plate-like body are not restricted by the diameter of the mounting hole, and the lower end of the elastic body can be locked in a stable state with an appropriate shape and size according to the elastic body, thus stabilizing the display body. And it can be fixed securely. Further, in the display device of the present invention, since the lower part of the leg itself is projected outward in the circumferential direction to form the locking portion, the display device main body and the elastic body are composed of two parts, that is, a small number of parts. In addition, the display main body can be fixed by a simple work of compressing and deforming the elastic body between the locking portion projecting outward at the lower portion and the rear surface of the lid to the leg portion projecting to the rear surface side of the lid.

Further, in the display device of the present invention, since the elastic body is a coil spring, it is fitted so as to surround the leg portion between the engaging portion of the leg portion projecting to the back side and the back surface of the lid. The repulsive elastic force of the inserted coil spring can be effectively and uniformly applied along the length direction of the coil spring, and the display tool body can be fixed stably and reliably. Furthermore, in the display device of the present invention, the elastic body is a coil spring, and the engaging portion for engaging the coil spring is provided on the locking portion of the leg portion and / or the back surface of the lid,
The lateral movement of the coil spring fitted along the legs is restricted, and the vibration of the lid is not released, and the engagement is released even against the load of the vehicle directly acting on the display body. Therefore, it is possible to provide a display tool that maintains a stable and reliable fixed state. Further, since the positions of the upper end portion and / or the lower end portion of the coil spring are restricted by the above engagement, the coil spring is deformed due to fatigue or the like (the diameters of the upper and lower end portions are increased).
Is prevented, the reduction of the repulsive elasticity is prevented, and a stable and reliable fixed state can be maintained for a long period of time.
