Description

{A reclamation type signal lamp assembly of the ground}

The present invention relates to a floor-type walking signal device assembly, and more specifically, to a floor-type walking signal device assembly that can quickly and easily construct the floor-type walking signal device and improve the construction quality.

The floor-type pedestrian signal device is buried in the ground where a crosswalk is installed and emits signal light through the upper surface. Floor-type pedestrian signal devices are highly regarded for their effectiveness because they can be located in the line of sight while providing the function of a stop line or guide line to pedestrians. In particular, in line with the recent increase in the number of pedestrians walking while looking at their smartphones, it has the advantage of being able to easily provide signal information to pedestrians.

However, unlike traffic lights installed on stilts, floor-type pedestrian signal devices are buried in the ground, such as concrete or asphalt, which forms the boundary between the roadway (crosswalk) and the sidewalk, and emit signal light with their upper surface exposed to the outside. Therefore, there is a problem that the case may be damaged if a large load or impact is repeatedly applied to the part of the case exposed to the outside.

In particular, floor-type walking signal devices have pedestrians, heavy vehicles, and motorcycles repeatedly passing through the upper surface of the case exposed to the outside, so when cracks or damage occur in the case, the damaged area is used to pass inside. There is a risk that moisture may penetrate and cause malfunction or breakdown of the pedestrian signal device. For this reason, there is a need to develop a walking signal device that can secure excellent durability even under large loads or impacts applied from the outside.

The matters described in the above background technology are intended to aid understanding of the background of the invention and may include matters that are not disclosed prior art.

The technical problem to be solved by the present invention is to provide a floor-type walking signal device assembly that can quickly and easily construct a plurality of floor-type walking signal devices and improve the construction quality.

The floor-type walking signal device assembly according to an embodiment of the present invention for solving the technical problems described above is a floor-type walking signal device assembly in which a plurality of floor-type walking signal devices are interconnected. is the main body; LED module disposed on the main body; and a cover part that surrounds the LED module and is coupled to the main body, wherein a coupling protrusion is formed on one side wall of the main body and/or one side wall of the cover part, and a coupling protrusion is formed on the other side wall of the main body and/or the other side wall of the cover part. A coupling groove having a biting shape is formed, and a plurality of floor-type walking signal devices are arranged in a row, so that the coupling protrusions of the floor-type walking signal device engage and interconnect with the coupling grooves of other floor-type walking signal devices, and the coupling protrusions and coupling grooves are connected to each other. The shape is formed to be the same in the thickness direction of the main body, the coupling groove is formed in a recessed shape in the other side wall of the main body and/or the cover part, and the coupling protrusion and the coupling groove are used to connect the floor-type walking signal device. The protrusion is engaged and coupled with the coupling groove of another floor-type walking signal device, and is formed to have a shape structure that limits movement of the main body and/or the cover in the longitudinal direction of the main body.

Here, a plurality of floor-type walking signal devices may be arranged in a straight line.

In addition, floor-type walking signal devices that are adjacent to each other may be connected to each other by having engaging protrusions and engaging grooves fitted in the vertical direction.

Meanwhile, the floor-type walking signal device assembly according to another embodiment of the present invention is a floor-type walking signal device assembly in which a plurality of floor-type walking signal devices are interconnected with a connecting member in between, and the floor-type walking signal device includes a main body. wealth; LED module disposed on the main body; and a cover part that surrounds the LED module and is coupled to the main body, wherein a coupling protrusion is formed on one side wall of the main body and/or one side wall of the cover part, and a coupling protrusion is formed on the other side wall of the main body and/or the other side wall of the cover part. A coupling groove having a biting shape is formed, and the connecting member has a groove coupled to the coupling protrusion of the floor-type walking signal device on one side, and a protrusion coupled to the coupling groove of the floor-type walking signal device on the other side. The coupling protrusion of the walking signal device is formed to have the same shape in the thickness direction of the main body, and the groove of the connecting member has the same shape in the thickness direction of the connecting member and is recessed inward on the side wall of the connecting member. It is formed, and the engaging protrusion of the floor-type walking signal device is engaged and coupled with the groove of the connecting member, and is characterized in that it is formed to have a shape structure that limits movement of the main body and/or the cover in the longitudinal direction of the main body.

Here, the side walls of the main body and/or the cover may have outer surfaces formed as inclined surfaces, and both sides of the connecting member may be formed as inclined surfaces corresponding to the inclined surfaces of the side walls.

Additionally, the connecting member may have a wedge shape when viewed from the top.

Additionally, a plurality of the floor-type walking signal devices may be arranged in a curved line.

In this case, adjacent floor-type walking signal devices may be connected to each other by fitting the coupling protrusion of the floor-type walking signal device and the groove of the connecting member in the vertical direction.

According to the floor-type walking signal device assembly structure of the present invention, constructability can be improved because a plurality of floor-type walking signal devices can be quickly and easily connected and constructed by combining the coupling protrusions and the coupling grooves, and the connection between the walking signal devices The quality of construction can be improved by ensuring that spacing and alignment are always kept constant.

In addition, a plurality of constructed walking signal devices form a structurally strong connection structure by combining the coupling protrusions and coupling grooves, so that even if a load or impact is applied to one side of the walking signal device, the walking signal of the other adjacent side is maintained. Since lateral support can be secured by the device, load and impact can be effectively distributed and attenuated. Accordingly, damage to the cover part caused by excessive deformation of the cover part due to load and impact can be prevented.

In addition, when constructing a walking signal device in a curved section, it is possible to construct a plurality of walking signal devices densely with even spacing and even alignment through a connecting member, so the walking signal device constructed in a curved section Construction quality can be greatly improved.

In addition, the connecting member interposed between the walking signal devices supports the load and impact applied to the walking signal device from the side and distributes it to other adjacent walking signal devices, thereby preventing the walking signal device from being easily damaged by load and impact. This can prevent the walking signal device from being pushed laterally by the load and becoming misaligned.

In addition, as the connecting member has a wedge shape inclined in the height and width directions of the walking signal device, due to the injection characteristics, even when a walking signal device with an external surface having an inclined surface is connected and constructed in a curved section, the walking signal devices are wedge-shaped. The quality of construction can be improved because it can be connected in the most dense structure using connecting members.

In addition, as the upper surface of the connecting member is constructed to be placed at the same height as the upper surface of the walking signal device, there is a risk of safety accidents that may occur due to pedestrians, motorcycles, etc. being caught or interfered with by steps while passing by the walking signal device. There is an advantage in that it can be prevented in advance, and cleaning work such as foreign substances attached to the upper surface of the walking signal device can be easily performed.

In addition, since the cover and main body of the walking signal device are assembled using a surface pressing method using nuts and bolts, it is possible to prevent moisture or foreign substances from penetrating into the walking signal device, and the fastening parts of the cover and main body are made of synthetic resin. It is also possible to increase durability by preventing cracking that occurs.

In addition, when the nut and bolt are fastened, a strong elastic pressing force is maintained through the elastic member, so that the bolt is not easily loosened from the nut unless an external force is applied, thereby maintaining a firm fastening force between the main body and the cover.

In addition, as the head of the nut is formed in a non-penetrating structure in which the tip of the bolt does not penetrate, the tip of the bolt fastened to the nut is not exposed above the upper surface of the cover part, thereby preventing damage to the bolt caused by the tip of the bolt coming into contact with external moisture. It can prevent corrosion and prevent safety accidents that may be caused by pedestrians or vehicles interfering with the tip of the bolt protruding from the top.

In addition, since the sealing member attached to the lower part of the head of the nut seals between the nut and the nut insertion hole, it is possible to prevent external moisture or foreign substances from entering the nut insertion hole and penetrating into the inside of the walking signal device. This prevents moisture from corroding bolt and nut fastening areas and reducing fastening force.

In addition, the cover part and the main body are assembled by inserting a nut from the upper part of the side wall of the cover part and passing a bolt through the lower part of the main body and fastening it to the nut, so that when the walking signal device is embedded in the ground and installed, the bolt cannot be loosened from the outside. Since it is impossible to disassemble the walking signal device, problems such as a third party arbitrarily disassembling the walking signal device and threatening pedestrian traffic safety can be prevented.

In addition, as an elastic member is provided between the base surface of the main body and the reflector to elastically adhere the reflector to the cover, the load applied to the cover is effectively distributed and absorbed by the elastic member through the reflector, causing cracks in the cover. It can prevent cracks from occurring and damage to the cover part. Accordingly, there is an advantage in that the load capacity of the walking signal device can be increased and durability can be improved, thereby greatly improving the service life of the walking signal device.

In particular, the walking signal device of the present invention forms one body and supports the load in a state in which the reflector and the cover part are in strong contact with each other due to the elastic repulsion force of the elastic member, so that the cover part exhibits elastic behavior within the yield point, thereby causing the load. This minimizes the deformation of the cover part and prevents the cover part from being easily damaged. Accordingly, it is possible to prevent moisture from penetrating through damaged parts of the cover and causing malfunction or breakdown of the walking signal device, which has the advantage of significantly reducing time and cost for maintenance of the device.

In addition, for assembly and alignment between the main body and the reflector, an elastic member is installed inside a plurality of holes formed on the base surface of the main body, and the elastic member elastically supports the lower protrusion of the reflector inserted into the hole. By doing so, there is no need to additionally provide a separate mechanical device or installation space for the installation of the elastic member on the main body or reflector, thereby reducing the number of installed parts in the walking signal device and increasing internal space utilization, making the walking signal device It has the advantage of being able to achieve miniaturization.

In addition, the elastic member having a coil spring structure is configured to be supported inside the hole on the base surface while being inserted into the stepped fitting part formed on the lower protrusion of the reflector, thereby preventing misalignment between the lower protrusion of the reflector and the elastic member. It has the advantage of effectively absorbing and distributing the load by fully transferring the load applied from the top to the elastic member through the lower protrusion of the reflector.

In addition, the base surface of the main body is divided into a first area arranged on the roadway side and a second area arranged on the sidewalk side based on the longitudinal center line of the main body, and the number of elastic members installed in the first area is divided into the second area. The area on the side of the roadway where a relatively large load is applied by forming more elastic members than the number of elastic members installed in the first area or by forming the elastic modulus of the elastic members installed in the first area to be larger than the elastic modulus of the elastic members installed in the second area. By increasing the number of installed elastic members or the elastic strength, the load applied differently in each area can be efficiently distributed through the elastic members, which has the advantage of maximizing the effect of absorbing and distributing the load.

In addition, as protruding ribs with a lattice arrangement are formed on the inner surface of the cover part, the structural rigidity of the upper plate area inside the border of the cover part, which is relatively vulnerable to load, can be improved, and the upper plate area of the cover part is easily deformed by the applied load. It can prevent damage or damage. In addition, as the ribs are formed in a lattice array structure, it is possible to prevent the open first hole of the cushioning sheet or the open upper part of the reflector from being obscured by the ribs, so that the signal light emitted from the LED module is transmitted to the outside through the cover part. By being transmitted normally, it is possible to prevent the visibility of pedestrians from being reduced.

In other words, the gasket 600 can be provided to prevent problems such as disconnection or short circuit due to corrosion of the circuit pattern formed in the LED module 200 and the driving module 400 when moisture, moisture, etc. flows into the interior from the outside. there is. The gasket 600 may be a rubber gasket such as EPMD or Viton, but is not necessarily limited thereto.

The cushioning sheet (S) is interposed between the upper surface 320 of the reflector 300 and the inner surface of the cover part 500, so that when the load is released from the upper part of the cover part 500, the upper surface 320 of the reflector 300 and A buffering action against the load can be performed between the inner surfaces of the cover portion 500. This cushioning sheet (S) may be made of materials such as silicone, rubber, and sponge.

Since the first hole (H1) of the buffer sheet (S) is formed in response to the open upper part 321 of the reflector 300, even if the buffer sheet (S) is placed on the upper surface 320 of the reflector 300, the reflector It does not cover the open upper part 321 of 300. In addition, since the second hole (H2) of the buffer sheet (S) is formed in response to the upper protrusion (322) formed on the upper surface of the reflector (300), the second hole (H2) of the buffer sheet (S) is formed on the reflector (300). ) By being fitted into the upper protrusion 322, the cushioning sheet S can be easily assembled by aligning it at the exact assembly position on the upper surface of the reflector 300.

Meanwhile, the main body 100 may have engaging protrusions P1 and engaging grooves G1 formed on both opposing side walls 101 and 102, respectively.

In addition, the cover portion 500 may have engaging protrusions (P2) and engaging grooves (G2) formed on both opposing side walls (532 and 533), respectively. The coupling protrusion (P2) is formed to protrude in one or more numbers on one side wall 532 along the longitudinal direction of the cover portion 500, and the coupling groove (G2) is recessed in one or more numbers in the other side wall 533. can be formed. The coupling protrusion (P2) and the coupling groove (G2) may be formed in a shape that can be engaged with each other to connect the walking signal devices.

In this case, the engaging protrusions (P2) and engaging grooves (G2) disposed on both side walls 532 and 533 of the cover part 500 are between a plurality of nuts N1 installed along the side walls 530 of the cover part 500. Can be placed in an area. When the engaging protrusion (P2) and the engaging groove (G2) are formed adjacent to the nut (N1), the engaging protrusion (P2) and the engaging groove (G2) are directly attached to the nut insertion hole (535), thereby increasing structural rigidity. It may become vulnerable, which may cause damage to the fastening portion of the coupling protrusion (P2) and coupling groove (G2). Therefore, by placing the engaging protrusion (P2) and the engaging groove (G2) in the area of the cover portion side walls 532 and 533 between the nut (N1) and the nut (N1) relatively far from the nut insertion hole (535), the engaging protrusion ( It is possible to prevent damage to the fastening portion of P2) and the coupling groove (G2).

In addition, when the coupling groove (G2) disposed on the other side wall 533 of the cover portion 500 opposite the coupling protrusion (P2) is formed in a recessed structure on the outer surface of the side wall 533, the nut insertion hole Since 535 and the coupling groove (G2) are adjacent to each other, the structural rigidity of the region where the coupling groove (G2) is formed may become weak. Accordingly, a protruding end 534 that protrudes outward is formed on the outer surface of the side wall 533 of the cover portion 500 where the coupling groove G2 is disposed, and a coupling groove G2 is formed in the protruding end 534. ) can be configured to form. Correspondingly, a protruding end 103 having a coupling groove G1 corresponding to the protruding end 534 of the cover unit 500 may be formed on one side wall 102 of the main body 100. When configured in this way, the structural rigidity of the portion where the coupling groove (G2) is formed can be improved and the fastening portion of the coupling protrusion (P2) and the coupling groove (G2) can be prevented from being damaged.

The coupling protrusion (P1) and the coupling groove (G1) formed on the main body 100 have positions and numbers corresponding to the coupling protrusion (P2) and the coupling groove (G2) formed on the cover part 500 in the vertical direction, respectively. It may be formed to have a corresponding shape. Accordingly, as shown in FIG. 2, when the main body portion 100 and the cover portion 500 are assembled together, the respective coupling protrusions (P, P2) and coupling grooves (G1, G2) overlap each other in the vertical direction. The walking signal device 1 may have a structure in which a pair of coupling protrusions (P) and coupling grooves (G) are formed on both side walls.

In this way, a pair of coupling protrusions (P) and coupling grooves (G) have a shape capable of engaging with each other and are arranged symmetrically on both opposing side walls of the walking signal device (1), thereby forming a coupling protrusion on one side of the walking signal device (1). By combining the coupling grooves (G) formed on (P) and the other walking signal device (1), a plurality of walking signal devices (1) can be simply and easily connected in line for construction.

In the embodiment, a structure in which engaging protrusions (P1, P2) and engaging grooves (G1, G2) are formed on both the main body 100 and the cover unit 500 is shown as an example, but the engaging protrusions (P1, P2) and The coupling grooves G1 and G2 may be formed only on either the main body 100 or the cover 500. In addition, the shape of the coupling protrusions (P1, P2) and the coupling grooves (G1, G2) is not limited to the shape shown in the embodiment as long as it is a structure that can be coupled in a way that engages with each other, and can be changed and applied to various shapes. there is.

The connection between the plurality of walking signal devices (1) using the coupling protrusion (P) and the coupling groove (G) is, as shown in FIG. 8, the coupling protrusion (P) formed on one side of the walking signal device (1) and The coupling grooves (G) formed on the other walking signal device (1) may be engaged with each other by fitting in the vertical direction.

In the embodiment, a structure in which the coupling protrusion (P) and the coupling groove (G) are coupled to each other in a vertical direction is shown as an example, but it can also be configured to be coupled in a way that the coupling protrusion and the coupling groove are fitted in the horizontal direction. . For example, the protruding end portions located on both sides of the coupling groove (G) are configured to temporarily open or retract due to elastic deformation, thereby connecting the coupling protrusion (P) of one side of the walking signal device (1) to the other side of the walking signal device (1). It can also be configured to be elastically coupled by pushing it horizontally into the coupling groove (G) of.

Meanwhile, FIG. 5 is a partial perspective view of the drive module and the elastic member in the main body of FIG. 3 disassembled.

Referring to FIG. 5, the main body 100 may be formed with an installation groove 120 for installing the drive module 400. This installation groove 120 may be provided in the space between the base surface 110 and the protective housing 180 to which the cable C is connected.

The driving module 400 is provided to control the driving of the LED module 200, and a plurality of fixing grooves 410 may be formed on the edge at regular intervals. In addition, the main body 100 may have a fixing hole 121a formed on each of the plurality of installation surfaces 121 provided in the installation groove 120, and this fixing hole 121a is used to fix the drive module 400. It may be formed corresponding to the groove 410. Therefore, the drive module 400 may be detachably coupled to the installation surface 121 of the main body 100 by fastening means (not shown) such as a bolt penetrating the fixing groove 410 and the fixing hole 121a. You can.

The main body 100 may have a plurality of holes 111 formed on the base surface 110 located around the installation groove 120 to which the lower protrusion 332 of the reflector 300 can be coupled. A plurality of holes 111 formed on the base surface 110 and a plurality of lower protrusions 332 formed on the lower surface of the reflector 300 allow the LED module 200 and the reflector 300 to be positioned at designated positions of the main body 100. It makes alignment possible and also provides ease of assembly.

As for the plurality of holes 111 formed in the base surface 110, one pair may be symmetrically arranged on one side with respect to the installation groove 120, and two pairs may be symmetrically arranged on the other side. Accordingly, a total of six holes 111 may be formed in an array on the base surface 110 as a whole. The formation location and installation number of the holes 111 may be changed in various ways to suit various design specifications such as load resistance, shock resistance, and vibration resistance of the walking signal device 1.

An elastic member 700 having a coil spring shape may be installed inside the plurality of holes 111 formed in the base surface 110. The elastic member 700 may elastically support the lower protrusion 332 of the reflector 300 when inserted into the hole 111. The elastic member 700 is elastically compressed inside the hole 111, and the reflector 300 can be pressed upward by the elastic repulsion force resulting from the elastic compression to strongly adhere to the inner surface of the cover portion 500. That is, the reflector 300 is pressed upward by a strong elastic repulsion force acting through the plurality of elastic members 700 and is strongly elastically adhered to the inner surface of the cover part 500, so that the reflector 300 is applied from the upper part of the cover part 500. Deformation of the cover portion 500 can be minimized by attenuating the applied load (or impact). This will be explained in more detail later.

FIG. 6 is a cross-sectional view taken along section A-A' of FIG. 2.

Referring to FIGS. 3, 4, and 6, the main body 100 has a plurality of first insertion holes 131 formed at intervals along the circumference of the upper edge 130, and the circumference of the lower edge 140. A plurality of second insertion holes 141 may be formed at intervals along .

The first insertion hole 131 and the second insertion hole 141 are formed to be connected to each other in the vertical direction, and the diameter of the first insertion hole 131 may be formed to be smaller than the diameter of the second insertion hole 141. there is. That is, a step surface f may be formed between the first insertion hole 131 and the second insertion hole 141 due to a difference in diameter.

The main body 100 and the cover 500 may be coupled to each other using a fastening means such as a bolt B1. In an embodiment of the present invention, an example in which a bolt is used as a fastening means will be described. The bolt (B1) is inserted through the second insertion hole 141 at the lower part of the main body 100 and can penetrate the first insertion hole 131, and the fastening hole 610 of the gasket 600 and the cover part ( It may pass through the bolt hole 531 formed in the lower part of the side wall 530 of the 500 and be fastened to the nut hole N1a of the nut N1 inserted from the upper part of the cover part 500.

In this case, the bolt (B1) may be fastened to the nut (N1) while one or more elastic members (SW) such as spring washers are inserted. Here, the head (h) of the bolt (B1) may be supported by the step surface (f) between the first insertion hole (131) and the second insertion hole (141). In addition, the elastic member (SW) can be elastically supported between the head (h) of the bolt and the step surface (f) in a state in which the bolt (B1) and the nut (N1) are fastened. This joint structure using the bolt (B1) and nut (N1) has the advantage of enabling a solid connection and reducing part production costs and product production costs.

The nut N1 may be configured as a long nut. The nut N1 may have a polygonal head portion N1b. In the embodiment, the head portion (N1b) of the nut (N1) is shown as an example formed in a hexagonal structure.

A plurality of nut insertion holes 535 into which the nut N1 is inserted may be formed in the side wall 530 of the cover portion 500. At the top of the nut insertion hole 535 is a polygonal seating groove that has a groove shape corresponding to the polygonal head N1b of the nut N1 and into which the polygonal head N1b of the nut N1 can be seated and engaged with each other. (Diagram not shown) may be formed. Accordingly, when the nut N1 is inserted into the nut insertion hole 535, the polygonal head N1b is engaged with the polygonal seating groove, so that rotation does not occur within the nut insertion hole 535.

The polygonal head N1b of the nut N1 may be formed in a non-penetrating structure in which the tip of the bolt B1 does not penetrate. Accordingly, when the bolt B1 is fastened to the nut N1, the tip of the bolt B1 is not exposed above the upper surface of the cover portion 500. In addition, a rubber ring-shaped sealing member OR that can seal between the nut N1 and the nut insertion hole 535 of the cover part 500 may be coupled to the nut N1. At this time, a circular groove (N1c) into which the sealing member (OR) can be inserted may be formed on the outer surface of the nut (N1) located below the polygonal head (N1b). This nut (N1) is inserted into the nut insertion hole (535) of the cover part (500) so that the head part (N1b) does not protrude above the top surface of the cover part (500). It may be formed to be disposed at the same or lower position as the upper surface of 500.

In this way, the present invention is a method of inserting the nut (N1) from the upper part of the side wall 530 of the cover part 500 and then passing the bolt B1 through the lower part of the main body part 100 to fasten it to the nut N1. Because the part 100 and the cover part 500 are assembled together, it is virtually impossible to disassemble the walking signal device 1 by loosening the bolt B1 from the outside when the walking signal device 1 is built and embedded in the ground. do. Accordingly, it is possible to prevent problems such as impeding pedestrian traffic safety by arbitrarily disassembling the pedestrian signal device 1 by an unauthorized third party.

In addition, in the case of the general walking signal device used previously, the body and cover made of synthetic resin were assembled by simply fastening bolts, so the phenomenon of the bolt fastening part of the body or cover being broken due to the tightening force of the bolt. It happened often. However, the walking signal device 1 of the present invention inserts a long nut N1 from the top into the nut insertion hole 535 formed on the side wall 530 of the cover portion 500, At the bottom of the main body 100, the bolt (B1) is sequentially passed through the second insertion hole 141, the first insertion hole 131, the fastening hole 610, and the bolt hole 531 to secure the nut (N1). Assembly is performed by fastening to the nut hole (N1a).

That is, in the walking signal device 1 of the present invention, the head N1b of the nut N1 and the head h of the bolt B1 are oriented in opposite directions on the cover 500 and the main body 100, respectively. Since the main body 100 and the cover 500 are assembled in a surface pressing structure that presses and adheres to each other while being supported by the main body 100 and the cover 500, there is a gap between the gasket 600. It adheres tightly without any damage, preventing moisture or foreign substances from penetrating from the outside, and cracking at the fastening area, which occurs when bolts are directly fastened to the cover or main body made of synthetic resin, does not occur at all, as in the past. In addition, as the long long nut (N1) and the bolt (B1) have a large contact area and are fastened to each other, the fastening force between the main body 100 and the cover 500 is maintained more firmly, so that the walking signal device (1) By increasing durability, the service life can be extended.

In addition, the present invention is such that the plurality of elastic members (SW) coupled to the bolt (B1) are elastically supported between the head (h) and the step surface (f) of the bolt, so that the bolt (B1) fastened to the nut (N1) ) maintains a strong elastic pressing force through the elastic member (SW) and is not easily loosened from the nut (N1) unless an external force is applied, thereby maintaining a firm fastening force between the main body 100 and the cover portion 500. Accordingly, a solid sealed structure without gaps is formed between the main body 100 and the cover 500, thereby preventing moisture or foreign substances from penetrating into the walking signal device 1.

In addition, when the nut (N1) is inserted into the nut insertion hole (535), the polygonal head (N1b) of the nut (N1) is seated in the polygonal seating groove of the nut insertion hole (535) and engages with each other, so that the nut (N1) ) and the bolt (B1), the advantage is that the nut (N1) can be prevented from spinning around in the nut insertion hole (535) and the bolt (B1) can be fastened more easily. there is.

In addition, as the polygonal head N1b of the nut N1 is formed in a non-penetrating structure in which the tip of the bolt B1 does not penetrate, the bolt B1 is Since the tip of the bolt is not exposed above the upper surface of the cover portion 500, corrosion of the bolt caused by the tip of the bolt (B1) coming into contact with external moisture can be prevented, and pedestrians, vehicles, etc. can prevent the bolt (B1) protruding upward. ) can prevent safety accidents that may occur due to interference with the tip of the device.

In addition, as a sealing member (OR) capable of sealing between the nut (N1) and the nut insertion hole 535 is provided below the head (N1b) of the nut (N1), the nut (N1) and the bolt (B1) In the fastened state, it is possible to prevent external moisture (or foreign substances) from entering the nut insertion hole 535 and penetrating into the walking signal device (1), and external moisture causes the bolt (B1) and nut ( N1) It is possible to prevent the problem of corrosion of the fastening area and lowering the fastening force.

In addition, the nut N1 inserted into the nut insertion hole 535 of the cover part 500 is disposed at a position where the upper surface of the head part N1b is equal to or lower than the upper surface of the cover part 500, so that the nut N1 is inserted into the nut insertion hole 535 of the cover part 500. As the head part N1b does not protrude above the upper surface of the cover part 500, the upper surface of the cover part 500 where the nut N1 is installed has a flat and neat appearance structure, thereby improving construction quality, and the cover part ( 500), it has the advantage of reducing the risk of safety accidents that may occur when pedestrians, motorcycles, or vehicles passing by step on the protruding nut interfere with it.

Meanwhile, Figure 7 is a cross-sectional view taken along section B-B' of Figure 2, showing the lower protrusion of the reflector being elastically supported by an elastic member while inserted into the hole formed on the base surface of the main body.

As shown in FIG. 7, the coil spring-shaped elastic member 700 is inserted into the plurality of holes 111 formed on the base surface 110 of the main body 100, and the lower end of the hole 111 is It may be supported on the bottom surface and the top may be supported on the lower protrusion 332 of the reflector 300. The elastic member 700 may be elastically compressed to a certain extent by the force applied from the upper portion of the lower protrusion 332 of the reflector 300 when the cover portion 500 is assembled to the main body portion 100.

On the other hand, the reflector 300 may be strongly elastically adhered to the inner surface of the cover portion 500 by the elastic repulsion force exerted in the upward direction by the plurality of elastic members 700. In this way, the reflector 300 is strongly elastically adhered to the inner surface of the cover part 500 due to the strong elastic repulsion force acting upward through the plurality of elastic members 700, thereby reducing the load ( or impact) can be partially offset through the upward pressure of the reflector 300 to prevent the cover portion 500 from being excessively deformed beyond elastic deformation due to load and impact.

The reflector 300 has a stepped fitting portion 334 at the lower end of the lower protrusion 332, which has a diameter smaller than the diameter of the lower protrusion 332 into which the elastic member 700 can be inserted, as shown in FIG. ) can be formed. As the elastic member 700 is fitted and coupled to the fitting portion 334 of the lower protrusion 332, the elastic member 700 and the lower protrusion 332 are aligned at the correct position in the vertical direction to cover the cover. Since the load applied from the upper part of the unit 500 can be completely transmitted to the elastic member 700 through the lower protrusion 332 of the reflector 300, the load and shock are effectively absorbed and absorbed through the plurality of elastic members 700. It can be dispersed.

In the case of a typical existing walking signal device, the upper surface of the reflector and the lower surface of the cover were spaced apart to form an empty space, and the synthetic resin cover had a thick structure to withstand the load applied from the upper part of the cover. Therefore, when a strong physical impact is applied to the upper part of the cover part, the upward support force provided by the reflector at the bottom of the cover part is not secured, and the cover part is excessively deformed downward, causing cracks to occur in the cover part, and moisture to the cracked part. There was a problem of this penetration causing malfunction or failure of the device.

However, in the present invention, the reflector 300 is elastically adhered to the inner surface of the cover part 500 located at the top due to a strong elastic repulsion force acting through the plurality of elastic members 700, The applied physical load and impact are primarily distributed through the reflector 300 having a lattice structure, secondarily buffered and absorbed through the plurality of elastic members 700, and then transmitted to the main body 100. ) By dispersing it into the surrounding ground surface, it is possible to prevent cracks or damage caused by excessive deformation of the cover part 500 due to load and impact.

For example, when a heavy object such as a vehicle or motorcycle passes over the cover part 500 of the walking signal device 1 exposed on the ground and a large load is applied to the cover part 500, a plurality of elastic members 700 The reflector 300, which is strongly adhered to the inner surface of the cover part 500 due to the upward pressure caused by ), forms one body with the cover part 500 and supports and distributes the load applied from the top in the opposite direction, thereby attenuating a certain portion. The load can be buffered and absorbed through the plurality of elastic members 700 and then distributed into the surrounding ground surface through the main body 100.

Therefore, even when a large load or impact is applied to the upper part of the cover part 500, the cover part 500 is not excessively deformed beyond the yield point and has elastic behavior at a slight level within the yield point, thereby preventing excessive deformation. Damage to the cover portion 500 due to this can be prevented. Accordingly, it is possible to overcome the problem that the usable life of the walking signal device 1 is reduced due to external moisture penetrating into cracks caused by excessive deformation of the cover portion 500.

In the case of a type in which a cushioning sheet (S) is provided between the reflector 300 and the cover portion 500 as in the embodiment, the reflector 300 and the cover portion 500 act by a plurality of elastic members 700. The load can be additionally absorbed through the buffer sheet (S) by being strongly adhered to the buffer sheet (S) between them due to the elastic repulsion force. In addition, the load is supported and effectively distributed through the reflector 300, which is in close contact with the cover part 500 with the buffer sheet (S) in between, thereby preventing the cover part 500 from being excessively deformed by the load applied from the top. It can be prevented.

Therefore, as in the case of existing walking signal devices, when an empty space is formed due to separation between the upper surface of the reflector and the lower surface of the cover part, or when the support force by the reflector is not secured due to loose contact between the reflector and the cover part, the upper surface of the cover part It can prevent damage such as cracks that occur due to excessive deformation of the central part of the cover due to strong load and impact, and prevents moisture from penetrating into the cracked area and causing malfunction of the walking signal device. can do.

The elastic member 700 installed on the base surface 110 of the main body 100 is divided into an area AR1 of the base surface 110 close to the roadway 10 and an area of the base surface 110 close to the sidewalk 20. (AR2) can be configured by varying the number of installations.

The pedestrian signal device (1) embedded in the ground on one side of the crosswalk curb (30) installed between the roadway (10) and the sidewalk (20) has the base surface (110) of the main body (100) positioned between the sidewalk (20) and the roadway ( Since it is formed to be inclined upwardly in the direction 10), the inclined base surface 110 has a portion adjacent to the roadway 10 having a higher height than a portion adjacent to the sidewalk 20.

When a load is applied to the pedestrian signal device (1) by a large heavy vehicle or motorcycle, most cases occur when a vehicle or motorcycle running on the roadway (10) steps on the pedestrian signal device (1) and passes on the sidewalk (20). do. For this reason, the magnitude of the load applied to the cover part 500 by a vehicle or motorcycle that initially enters from the roadway 10 side to the sidewalk 20 side is the area AR1 of the cover part 500 close to the roadway 10 side. This may be larger than the area AR2 of the cover portion 500 close to the sidewalk 20 side.

In this way, in consideration of the situation in which a different size of load is applied to each internal area of the pedestrian signal device 1 when a vehicle or motorcycle, etc. proceeds from the roadway 10 to the sidewalk 20, in the present invention, the base of the main body 100 The surface 110 is divided into a first area AR1 arranged close to the roadway 10 side based on the longitudinal center line CL of the main body 100, and a second area arranged close to the sidewalk 20 side ( AR2), and the number of elastic members 700 installed in the first area AR1 may be greater than the number of elastic members 700 installed in the second area AR2.

For example, five elastic members 700 are installed in the first area (AR1) close to the roadway (10), and three elastic members (700) are installed in the second area (AR2) close to the sidewalk (20). You can. In this way, the number of elastic members 700 installed in the first area AR1 close to the roadway 10 is installed in a larger number than the elastic members 700 installed in the second area AR2 close to the sidewalk 20. By doing so, the plurality of elastic members 700 installed in greater numbers in the first area (AR1), where a relatively large load is applied, can absorb and buffer the load intensively, so that relatively more occurrences occur in the first area (AR1). It is possible to solve the problem of damage to the cover part 500.

As another embodiment, elastic members 700 having different elastic strengths may be installed in the first area AR1 and the second area AR2 of the base surface 110. For example, the number of elastic members 700 installed in the first area AR1 and the second area AR2 of the base surface 110 is the same, but the number of elastic members 700 installed in the first area AR1 and AR2 is the same. The elastic strength (stiffness) of the elastic member 700 installed may be greater than that of the elastic member 700 installed in the second area AR2.

In this way, the number or elastic strength of the elastic members 700 installed in the area of the cover unit 500 located on the side of the roadway 10 where a relatively large load is applied and the area located on the side of the sidewalk 20 where a small load is applied If configured differently, the load can be effectively absorbed and buffered according to the size of the load applied to each area of the cover part 500.

Apart from the effect of preventing excessive deformation of the cover part 500 by the plurality of elastic members 700, the cover part (500) is formed by forming a plurality of ribs (not shown) protruding in a lattice structure on the inner surface of the cover part 500. 500) can minimize deformation due to load.

In this case, in the type in which the buffer sheet (S) is installed between the reflector 300 and the cover part 500, the lower part of the rib having a lattice structure formed on the inner surface of the cover part 500 is the first hole of the buffer sheet (S). By forming it to be supported in close contact with the periphery of (H1), the lattice-structured ribs can be formed so as not to cover the open first hole (H) portion of the cushioning sheet (S).

In addition, in the case of the type in which the buffer sheet (S) is not installed between the reflector 300 and the cover part 500, the lower part of the rib of the lattice structure formed on the inner surface of the cover part 500 is the open upper part of the reflector 300. By forming it so that it is supported in close contact with the surrounding area (321), the ribs of the lattice structure can be formed so as not to cover the open upper part 321 of the reflector 300.

In this way, lattice-structured ribs are formed on the inner surface of the cover part 500, and the structural rigidity of the upper plate 520 of the cover part 500, which is relatively vulnerable to load, can be improved, so the cover part 500 It is possible to prevent the upper plate 520 from being excessively deformed by load.

Meanwhile, Figure 8 shows a plurality of walking signal devices connected to each other by coupling protrusions and coupling grooves. In addition, Figures 9 and 10 show a view of a plurality of walking signal devices interconnected from the top and side, respectively.

As mentioned above, the floor-type walking signal device 1 may be installed buried in a line connected to the ground on one side of the crosswalk curb 30 installed between the roadway 10 and the sidewalk 20. In this case, the plurality of walking signal devices 1 may be connected and installed in line in a mutually engaging manner between one or more engaging protrusions (P) and engaging grooves (G) formed on both sides opposite to each other in the longitudinal direction.

As shown in FIG. 8, when connecting a plurality of walking signal devices (1), the coupling protrusion (P) formed on one side of the walking signal device (1) and the coupling groove (G) formed on the other walking signal device (1) are connected. They can be connected by combining them with each other. As an example, a plurality of walking signal devices (1) are provided by inserting the coupling protrusion (P) of one side of the walking signal device (1) upward or downward into the coupling groove (G) of the other side of the walking signal device (1) to engage them with each other. You can connect them easily and quickly.

Previously, in order to construct a plurality of walking signal devices in a row on the ground, workers had to manually align the rows and columns of the walking signal devices, which resulted in poor constructability and a lot of construction time. There was a disadvantage, and if the worker was not an experienced worker, the spacing or rows between the installed pedestrian signal devices did not match, which greatly reduced the quality of the construction.

However, a plurality of walking signal devices (1) constructed in a connection manner as shown in Figure 8 using the structure of the walking signal device (1) of the present invention are a plurality of walking signal devices (1) connected to each other in a straight line as shown in Figures 9 and 10. Since the spacing and rows between the signal devices 1 are kept constant, the quality of construction can be greatly improved.

In addition, when connecting a plurality of walking signal devices, the construction is performed in a simple manner by inserting the coupling protrusion (P) of one side of the walking signal device (1) into the coupling groove (G) of the other side of the walking signal device (1). The work is very simple and construction time can be greatly shortened, which has the advantage of significantly reducing construction costs.

In addition, conventionally, a plurality of walking signal devices are buried in the ground at regular intervals and then filled with soil, etc. in the space between the walking signal devices, so when a load is applied from the top of the walking signal device, Although there was a disadvantage in that the lateral (horizontal) support between the walking signal devices was not secured, the present invention provides a plurality of walking signal devices (1) constructed in a row by combining the engaging protrusions (P) and the engaging grooves (G). Since they contact each other to form a solidly connected structure, even when a load is applied intensively to one walking signal device (1), lateral support is secured by the other neighboring walking signal device (1), thereby effectively supporting and distributing the load. There is an advantage in that the walking signal devices can be prevented from being damaged, and the spacing and alignment between the walking signal devices can always be kept constant even when a load is applied.

Figure 11 shows a modified example of the floor-type walking signal device installation structure according to the present invention.

As shown in FIG. 11, the walking signal device 1' has one or more coupling protrusions (P') formed on one of the two sides facing each other in the longitudinal direction, and a coupling protrusion (P') on the other side. One or more coupling grooves (G') having a shape that engages with the A plurality of pieces may be connected and installed in a row in such a way that they are interlocked with each other.

In this case, unlike the above-described embodiment, the coupling groove G' of the walking signal device 1' may be formed to be recessed inward on one side wall of the walking signal device 1'. That is, in the above-described embodiment, a protruding end was formed on one side of the walking signal device 1, and a coupling groove (G) was formed in the protruding end portion, but the walking signal device 1' shown in FIG. 11 is A protruding end may not be formed on one side wall portion, and the coupling groove G' may be formed in a recessed form inside the edge of the side wall.

Accordingly, in a state in which a plurality of walking signal devices (1') are interconnected and constructed by combining the coupling protrusion (P') and the coupling groove (G'), neighboring walking signal devices (1') are connected without a gap. By forming a more robust connection structure that is closely attached to each other, even if a load is applied to the walking signal device (1') on one side, lateral support can be secured by the walking signal devices ('1) on both sides adjacent to it. Therefore, the load can be effectively supported and distributed, and thus the walking signal device 1' can be prevented from being easily damaged by load and impact.

Meanwhile, Figures 12 and 13 show a plurality of floor-type walking signal devices constructed in a curved shape with connection members as viewed from the top and side, respectively.

The walking signal device 1 may be constructed in a structure in which a plurality of walking signal devices 1 are connected in a straight line as shown in FIGS. 9 and 10 mentioned above, but between the roadway 10 and the sidewalk 20. In a curved section where the boundary has a curved structure, a plurality of walking signal devices 1 may be constructed arranged in a row in a curved structure corresponding to the curved section.

Since the walking signal device (1) is manufactured in a rectangular shape with a certain standard, it may be difficult to construct a plurality of walking signal devices (1) by connecting them in a curved structure using a coupling protrusion (P) and a coupling groove (G). .

Therefore, when installing a plurality of walking signal devices (1) in a curved section, a coupling protrusion (P) is used to fill the space between the walking signal devices (1) and connect neighboring walking signal devices (1). It can be constructed using a connecting member (3) that can be connected to each other by a coupling groove (G).

When constructing a plurality of walking signal devices 1 by arranging them in a curved section, as shown in FIG. 12, spaced apart spaces in the shape of a fan (or wedge shape) may be generated between neighboring walking signal devices 1. You can. That is, a fan-shaped space (not shown in the drawings) may be formed between neighboring pedestrian signal devices 1 arranged in a curved section, with the width of the space gradually widening or narrowing from one side to the other. Therefore, the curved section is connected to the adjacent walking signal devices 1 by interposing the connecting member 3, which has an external shape corresponding to the shape of the fan-shaped space, between the neighboring walking signal devices 1. It can be constructed by connecting a plurality of walking signal devices (1) in series.

The connecting member (3) is formed with a groove portion (31) coupled to the engaging protrusion (P) of the walking signal device (1) adjacent to one side (3a), and the walking signal device (1) adjacent to the other side (3b). ) A protrusion 32 that is coupled to the coupling groove (G) may be formed. The grooves 31 and protrusions 32 formed on both sides 3a and 3b of the connecting member 3 can be engaged with the engaging protrusions P and the engaging grooves G of the neighboring walking signal device 1, respectively. It can be formed into any shape.

Here, the horizontal width of the connecting member 3 may be formed to have a width corresponding to the space gap formed between the neighboring walking signal devices 1. Therefore, when it is necessary to adjust the distance between neighboring walking signal devices 1, the distance between the walking signal devices 1 can be freely adjusted using the connecting member 3 corresponding to the width of the gap.

In addition, as another modified example of the connecting member 3, one side surface 3b of the connecting member 3 has an insertion groove (not shown) into which the protruding ends 103 and 534 of the neighboring walking signal device 1 can be inserted. poetry) can be formed. At this time, the insertion groove is formed in a recessed structure on one side (3b) of the connecting member (3) to have a shape corresponding to the outer shape of the protruding end (103, 534), and a walking signal device adjacent to the inner part of the insertion groove ( A protrusion 32 coupled to the coupling groove (G) of 1) may be formed. Accordingly, since the protruding ends 103 and 534 of the walking signal device 1 can be engaged with the protrusion 32 located inside the insertion groove while being inserted into the insertion groove of the connecting member 3, the connecting member 3 There is an advantage in that the quality of construction can be improved by ensuring that the distance between the both sides (3a, 3b) of ) and the neighboring pedestrian signal devices (1) is maintained constant.

Meanwhile, due to the nature of the main body portion 100 and the cover portion 500 of the walking signal device 1 being injection molded from a synthetic resin material, the side wall portion is tilted to facilitate extraction from the mold. can be formed. That is, as shown in FIG. 13, the outer surfaces of the side walls of the main body 100 and the cover 500 may be formed as an inclined surface SH. Accordingly, the walking signal device 1 in which the main body 100 and the cover 500 are assembled together may also have the outer surfaces of both side walls formed as inclined surfaces SH. Correspondingly, both surfaces 3a, 3b of the connecting member 3 on which the groove 31 and the protrusion 32 are formed are also formed with slopes corresponding to the slopes SH of both side walls of the walking signal device 1. can

In this way, the connecting member 3 is formed in a wedge shape whose outer surface is inclined in the height and width directions of the walking signal device 1, thereby forming a plurality of walking signal devices 1 with both side walls formed as inclined surfaces. Even in the case of construction in a curved section by connecting them together, it can be possible to densely connect and construct the curved section to maintain even alignment at even intervals using the wedge-shaped connecting member (3). The construction quality of the walking signal device 1 can be greatly improved.

In addition, when constructing a plurality of walking signal devices (1) in a curved section by connecting them in series through the connecting member (3), as shown in FIG. 13, the upper surface of the connecting member (3) is adjacent to the walking signal device. It can be formed to be placed at the same height as the top surface of (1). When constructed with this structure, even when a pedestrian or motorcycle passes by stepping on the upper surface of the walking signal device (1), the step caused by the height difference between the connecting member (3) and the walking signal device (1) Safety accidents such as pedestrians tripping or motorcycles overturning can be prevented.

In addition, when multiple pedestrian signal devices are constructed in a curved section without using connecting members, the space between neighboring pedestrian signal devices is excessively widened, and soil for filling is used excessively to fill the gap. The quality deteriorates, and even if the open space is filled with sand for filling, there is a disadvantage in that lateral support cannot be smoothly secured between neighboring pedestrian signal devices. On the other hand, since the present invention forms a structure in which neighboring walking signal devices (1) are firmly connected via the connecting member (3), even when a load is applied to the walking signal device (1) on either side, the connecting member ( By securing lateral support through the walking signal device (1) on the other side coupled via 3), the load can be effectively supported and distributed to prevent the walking signal device (1) from being easily damaged by the load, Even if a large load is applied, there is an advantage that the spacing and alignment between the walking signal devices 1 can always be maintained constant.
