【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 shown in the drawings is a base formed of hard rubber or the like in a substantially rod shape in order to connect and connect the blocking rod P2 to the tubular blocking rail P1 for railroad crossing on the base end side of the blocking rod. It is the end connection device body.

As shown in FIG. 1, the connection device main body 1 for the proximal end has a connection main body 2 to which a blocking rod P1 having a slightly larger diameter is fixed, and a blocking rod P2 having a slightly smaller diameter than the blocking rod P1. The connecting main body 2 and the connecting sub body 3 are connected to each other at a bending portion 19 by an elastic material so as to be bendable and recoverable.

That is, as shown in FIG. 2, in the connection main body 2, the spring insertion hole 21 and the wire insertion hole 22 having a diameter slightly smaller than the spring insertion hole 21 are continuously penetrated, and the connection main body is connected. A connection hole 6 is formed at the end on the side connected to 3.

Further, as shown in FIG. 2, the connecting sub-member 3 is provided with a projecting portion 7 which is loosely fitted in the connecting hole portion 6 of the connecting main body 2, and corresponds to the wire insertion hole 22 of the connecting main body 2. The insertion hole 23 is penetrated. The projecting portion 7 is formed in a substantially taper shape with a narrowed tip so that the connecting body 2 and the connecting sub-body 3 are bendable. In addition, the connection sub-body 3 is provided with a fitting portion 9 that comes into contact with a bending prevention body 8 of the connection main body 2 described later.

The shape of the fitting portion 9 will be described in detail later.

The connecting main body 2 and the connecting sub body 3 are connected by being tightened with a stainless wire 16 provided with a spring 11 which is an elastic material.

That is, as shown in FIG. 2, the wire 16 is inserted from the wire insertion hole 23 side of the connection sub-body 3 into the wire insertion hole 22 of the connection main body 2. A fixing piece 15 for fixing the wire 16 to the step portion 24 of the connection sub-body 3 is attached to the proximal end portion of the wire 16, and a bolt portion 17 is formed at the distal end portion. There is. The bolt portion 17 side of the wire 16 penetrates the coil spring 11 arranged in the spring insertion hole 21 of the connection main body 2 and is screwed by the nut 14 via the spring locking tool 10.

As shown in FIG. 1, the spring locking device 10 is arranged in the coil spring 11 and has a wire insertion hole 12 through which the wire 16 penetrates. A head portion 25, which is slightly larger than the diameter of the coil spring 11, is attached.

On the other hand, one end of the coil spring 11 is in contact with the step portion 18 of the connecting main body 2, as shown in FIG. Therefore, as shown in FIG. 2, when the nut 14 is screwed onto the bolt portion 17 of the wire 16, the coil spring 11 is pressed down by the step portion 18 of the spring insertion hole 21 and the head portion 25 of the spring locking tool 10. To be

By using the elastic force of the coil spring 11 as described above, the connection main body 2 and the connection sub body 3 are tightened.

As shown in FIG. 1, when the nut 14 is screwed onto the bolt portion 17 of the wire 16, the washer 13 is interposed so that the screw 14 can be smoothly tightened.

As shown in FIG. 1, the connection main body 2 constituting the base end connection device main body 1 used on the base end side of the cutoff rod has an outer diameter fitting to the inner diameter of the cutoff rod P1. Part 4 is provided. Further, as shown in FIG. 1, the connecting sub-body 3 is provided with a connecting portion 5 having an outer diameter that fits the inner diameter of the cutoff rod P2. The blocking rods P1 and P2 fitted in the respective connecting portions 4 and 5 are fixed by tightly fixing the blocking rods P1 and P2, for example, by wrapping them with adhesive tape.

Therefore, by forming the main body 1 of the proximal end connecting device in this way, the blocking rod P1 and the blocking rod P2 fixed to the connecting main body 2 and the connecting secondary body 3 are the springs of the connecting main body 2. Since the wire 16 is tightened by the elastic force of the spring 11 arranged in the insertion hole 21, the bent portion 13 which is the connecting portion between the connecting main body 2 and the connecting sub body 3 is bent well. It can be restored freely.

On the other hand, an end portion in the longitudinal direction of the connection main body 2 is provided with an approximately semi-cylindrical tubular bending preventing body 8 as shown in FIGS. The fold prevention body 8 can be maintained in its robustness by being integrally formed with the connection main body 2 as a part of the connection main body 2. As shown in FIG. 3, the inner surface of the bending prevention member 8 is in contact with the fitting portion 9 of the connection sub-member 3.

That is, as shown in FIGS. 1 and 2, in the fitting portion 9 of the connecting by-product 3, the end portion of the connecting by-product 3 and the lower surface of the projecting portion 7 are shaved, and the fitting surface 26 of the fitting portion 26 is loose. It is formed so as to be curved. Therefore, when the connection main body 2 and the connection sub body 3 are connected, as shown in FIG. 3, both ends of the inner surface of the bending preventing body 8 and both ends of the fitting surface 26 come into contact with each other.

Therefore, the bending preventing body 18 prevents the connecting main body 2 and the connecting sub body 3 from being bent downward in the railroad crossing. Further, when both ends of the inner surface of the bending preventing body 8 and the connecting sub-body 3 are connected, as shown in FIG. 3, both ends of the inner surface of the bending preventing body 8 and both ends of the fitting surface 26 come into contact with each other. Therefore, the connecting main body 2 and the connecting sub body 3 are prevented from being bent in the horizontal direction.

However, when a person or car C is trapped inside the railroad crossing, as shown in FIG. 6 and FIG. 7, it is possible to bend to the road side while being lifted slightly obliquely upward, Car C can safely escape from the railroad crossing. Similarly, it is possible to bend the railroad crossing to the side of the railroad line in a state where the railroad crossing is raised slightly obliquely upward. However, as described above, both ends of the inner surface of the folding prevention body 8 and the fitting surface 26 are Since both ends are in contact with each other, the connecting main body 2 and the connecting sub body 3 are not bent toward the railroad track side due to natural conditions such as strong wind and rain.

Next, the tip connection device main body 41 used on the tip side of the blocking rod will be described.

As shown in FIG. 4, this tip connection device main body 41 has a connection main body 42 to which a blocking rod P 2 having a slightly larger diameter is fixed, and a blocking rod P 3 having a diameter slightly smaller than that of the blocking rod P 2. And the connection sub-member 43.

As shown in FIG. 4, the connecting main body 42 is provided with a connecting portion 44 for connecting and fixing the cutoff rod P2. In addition, as shown in FIG. 4, the connecting sub body 43 is provided with a connecting portion 45 having an outer diameter that fits into the inner diameter of the shutoff rod P3. Then, when the cutoff rod P2 is fixed to the connection main body 42, as shown in FIGS. 1 and 2, the connection auxiliary body 50 is attached and fixed to the connection main body 42 by the bolt 56 so as to cut off the outer diameter of the connection main body 42. Adjust the difference in the inner diameter of the rod P2.

The connecting main body 42 and the connecting sub body 43 are connected to each other at the bent portion 57 by a resilient material so that they can be bent and restored.

That is, as shown in FIG. 5, the connection main body 42 is provided with a ring-shaped contact portion 58 that folds back the end portion of the cylinder having the spring insertion hole 55 and contacts the connection sub body 43. . A spring 48 is arranged in the spring insertion hole 55.

Further, as shown in FIG. 5, the connecting sub-member 43 is provided with a protruding portion 52 that is loosely fitted in the connecting hole portion 59 of the connecting main body 42, and the wire inserting hole 54 is provided in the protruding portion 52. Has been drilled. The projecting portion 52 is formed in a substantially tapered shape in which the tip portion is narrowed so that the projecting portion 52 is bendable in a state in which the connecting main body 42 and the connecting sub body 43 are connected.

The connecting main body 42 and the connecting sub body 43 are connected by being tightened by a stainless wire 47 having a spring 48 which is an elastic material.

That is, as shown in FIG. 5, the wire 47 is inserted from the wire insertion hole 54 side of the connection sub body 43 into the spring insertion hole 55 of the connection main body 42. The wire 47 is formed by bending one wire into a ring shape, and a fastening piece 46 for fastening the wire 47 by abutting on the stepped portion 53 of the connection sub-member 43 is attached to the base end portion thereof.

The tip portion of the wire 47 is connected to the coil spring 48 arranged in the spring insertion hole 55 of the connection main body 42. The connecting pieces 60 attached to both ends of the coil spring 48 are hooked on the tip end of the ring-shaped wire 47 to connect the wire 47 and the coil spring 48.

On the other hand, the connecting piece 60 of the coil spring 48 on the side opposite to the wire 47 is hooked on the locking rod 49 which is locked at the end of the connecting body 42. By utilizing the elastic force of the coil spring 48 in this way, the connection main body 42 and the connection sub body 43 are tightened.

Therefore, by forming the tip connection device main body 41 in this way, the blocking rod P2 and the blocking rod P3 fixed to the connection main body 42 and the connection sub body 43 are inserted into the spring insertion of the connection main body 42. Since the wire 47 is tightened by the elastic force of the spring 48 arranged in the hole 55, the bent portion 57, which is the connecting portion between the connecting main body 42 and the connecting sub body 43, is properly folded in the vertical and horizontal directions. The songs can be restored freely.

Therefore, when a person or automobile C is trapped inside the railroad crossing, as shown in FIGS. 5 and 6, the connection main body 42 and the connection sub body 43 forming the tip connection device main body 41 are located above the road side. Since the vehicle bends to, a person or car C can safely escape from the railroad crossing.

By the way, the base end connection device main body 1 and the tip end connection device main body 41 used on the base end side and the tip end side of the blocking rod are not limited to the above-described examples, and for example, the connection main bodies 2 and 42. And the connection sub-members 3 and 43 are not bent to form the bent portions 19 and 57, but the bent portion is formed in the proximal end connection device main body 1 and the distal end connection device main body 41 integrally formed of hard rubber or the like. 19, 57 may be formed.

Further, in the base end connection device main body 1 used on the base end side of the cutoff rod, the fixing means of the connecting portion 4 to the cutoff rod P1 can be appropriately selected.

That is, the base-end connecting device main body 1 is formed into a substantially rod-like shape with connecting portions 4 and 5 into which tubular blocking rails P1 and P2 are inserted and fixed at both ends. A bending portion 19 is provided so that the portions 4 and 5 can be mutually bent and restored by an appropriate elastic material, and the bending portion 19 is designed to be unfoldable in the railroad side direction and the downward direction in the railroad crossing. It is sufficient that the bending preventing body 8 is formed on the inner surface of the inner wall, and the specific structure and material thereof can be freely selected as appropriate.

Next, to explain its use, as shown in FIG. 6 and FIG. 7, the base end connecting device main body 1 is attached to the movable part of the circuit breaker, and the blocking rod P1 is connected thereto. The base end connection device body 1 is also attached to the other end of the shutoff rod P1 to connect the shutoff rod P1. Further, the tip end connecting device main body 41 is attached to the other end of P2, and the shutoff rod P3 is connected to form a crossing shutoff rod.

The crossing rod for railroad crossing shown in the figure connects three shutoff rods P1, P2, P3 by using two base end connection device bodies 1 and one tip connection device body 41. However, the present invention is not limited to this, and even if the number of the base end connection device main body 1 and the tip end connection device main body 41 to be used and the number of disconnection rods to be connected are changed depending on the size of the level crossing and the like. Good.

As described above, the railroad crossing blocking rod connects a plurality of barrier rods using the base end connecting device body 1 and the tip connecting device body 41. Therefore, as shown by the alternate long and two short dashes line in FIGS. 6 and 7, even when the railroad crossing bar is closed and the automobile C or the like is trapped inside the railroad crossing, the rail crossing bar is appropriately bent toward the road. Therefore, you can safely escape. Further, after the escape, as shown by the solid lines in FIGS. 6 and 7, the original state is immediately restored.

In addition, the blocking rod P2 has a risk that the blocking rod P2 is bent in the railroad side direction in the railroad crossing due to the bending prevention body 8 formed in the bending portion 19 of the base end connection device body 1. It is also possible to prevent it from hanging downward due to its own weight.
