  The igniting body 6 burns when ignited. For example, a sparking hand sparkler made by attaching an explosive to the tip of a handle made of bamboo chin or metal can be used. As shown in FIG. 3 (a), the igniting body support portion 5 that can support the igniting body 6 includes the igniting body support holes 51 that can be supported with the igniting body 6 standing at the tip of the support column 3. I have. When the heat guide body 6 is inserted into the heat guide body support hole 51 from the handle, the heat guide body 6 can be pushed into the heat guide body support hole 51. This igniting body support portion 5 is provided above the cracker support plate 4, whereby the igniting body 6 can be more easily attached to the igniting body support portion 5, and sparks are scattered. The burning conductor 6 can be seen without being obstructed by other parts of the apparatus.

  Furthermore, the igniting body support portion 5 includes a cylindrical member 52 that can cover the periphery without contacting the igniting body 6 standing in the igniting body support hole 51. The cylindrical member 52 has its lower end fixed around the igniting body support hole 51 provided at the upper end of the column 3, and the igniting body 6 is loosely inserted into the cylindrical member 52. The cylindrical member 52 includes an introduction hole 53 for introducing the first work yarn 8 a into the cylindrical member 52 and a lead-out hole 54 for leading the work yarn 8 a from the cylindrical member 52. The arrangement of the introduction hole 53 and the lead-out hole 54 is determined so that the in-process yarn 8a passing through the holes 53 and 54 can come into contact with the portion of the tubular member 52 where the explosives 6 are attached. Yes. The cylindrical member 52 includes an introduction groove 55 for introducing the second work yarn 8b into the cylindrical member 52 and a lead-out groove 56 for leading the work yarn 8b from the cylindrical member 52. The arrangement of the introduction groove 55 and the lead-out groove 56 is determined so that the in-process yarn 8b passing through these grooves 55, 56 comes into contact with the portion of the tubular member 52 where the explosive is attached to the igniting body 6. Yes. The cylindrical member 52 according to the present embodiment has the introduction hole 53 and the lead-out hole 54 at the upper and lower middle portions thereof, and has the introduction groove 55 and the lead-out groove 56 at the upper end thereof. The two in-process yarns 8 a and 8 b passing therethrough are positioned vertically within the cylindrical member 52. However, instead of the introduction hole 53 and the lead-out hole 54, a groove that functions in the same manner is formed at the upper end portion of the cylindrical member 52, or instead of the introduction groove 55 and the lead-out groove 56, the upper and lower middle portions of the tubular member 52 are formed. Alternatively, a hole that functions in the same manner may be formed, and the two in-process yarns 8 a and 8 b may be arranged at the same height in the cylindrical member 52.

  The first in-process yarn 8 has a starting end connected to the first connecting portion 22a of the elastic body 21a, a terminal end connected to the second connecting portion 43a, and a conduction hole 42a of the cracker support plate 4 between the starting end and the terminal end.

The tension to hold in the state is applied.

[Procedure for using cracker-use playground equipment 1]
Here, the use procedure of the cracker utilization playground equipment 1 is demonstrated. When using the cracker-use playground equipment 1, the cracker 10 and the light guide body 6 are attached to the playground equipment body 7. The first cracker 10a is inserted into and supported by the cracker support hole 41a of the cracker support plate 4, and the drawstring thereof is the first elastic body 21a after elastic deformation in which one end of the first in-process yarn 8a is connected. It is tied to the connecting portion 22a. The second cracker 10b is inserted into and supported by the cracker support hole 41b of the cracker support plate 4, and its pull string is the first elastic body 21b after elastic deformation in which one end of the second work thread 8b is connected. It is tied to the connecting portion 22b. The igniting body 6 is thrust into the igniting body support hole 51 of the igniting body support portion 5. In addition, even if the general crackers on the market are different in the axial size, the individual differences in the length of the drawstring are small, and further, as described above, the individual difference in the angle between the shaft and the busbar is also small. The length of the portion appearing on the lower portion from the cracker support plate 4 of the cracker and the length of the drawstring are small. Therefore, most of the commercially available general crackers can be attached to the cracker support plate 4, and the versatility of the cracker utilizing playground equipment 1 is high.

  In the cracker utilization play equipment 1 equipped with the cracker 10 and the igniting body 6 as described above, when the tip of the igniting body 6 is ignited, the igniting body 6 which is a fireworks emits a bee, sound and sparks from the tip. It burns toward the igniting body support portion 5 where there is. When the combustion position of the igniting body 6 reaches the cylindrical member 52, the in-process yarn 8 is burned out by the fire and heat of the igniting body 6. First, the in-process yarn 8b positioned in the cylindrical member 52 is burned out, and the tension applied to the in-process yarn 8b is released. As shown by the two-dot chain line in FIG. Recovers from elastic deformation. When the elastic body 21b recovers from the elastic deformation, the pull string of the cracker 10b connected to the elastic body 21b is pulled along with the displacement of the free end of the elastic body 21b, and the cracker 10b is ignited and squeals. Subsequently, the in-process yarn 8a positioned below in the cylindrical member 52 is burned out, and the cracker 10a is ignited and squeaks as before. If the two in-process yarns 8a and 8b are arranged at the same height in the cylindrical member 52, the two in-process yarns 8a and 8b burn out almost simultaneously, so that the two crackers 10a and 10b are almost simultaneously Can be sounded.

  As described above, in the cracker utilization play equipment 1 according to the present invention, there is a time lag (introduction time) from when the igniting body 6 is ignited until the cracker 10 rings, and the igniting body 6 burns during this time lag. The time until the cracker 10 sounds in addition to the moment when the cracker 10 sounds by watching the appearance and listening to the sound, seeing the elastic body 21 recovering from the elastic deformation, and watching the in-process yarn 8 burn out. Can enjoy. And, during this time lag, when the combustion position of the igniting body 6 gradually moves toward the igniting body support 5 side, the mood of the place is expected to rise because the mood is increased by waiting for the cracker 10 to ring. . Further, by selecting the height position of the in-process yarn 8 in the cylindrical member 52, the plurality of crackers 10 may be intermittently sounded at time intervals, or the plurality of crackers 10 may be sounded substantially simultaneously. it can.

  The elastic body 21 may be an elastic body such as a tension spring or rubber instead of the leaf spring and capable of displacement corresponding to the pulling allowance of the pulling string of the cracker 10. However, it is preferable to use a leaf spring as the elastic body 21 because the cracker utilizing playground equipment 1 can be configured easily and inexpensively and the dynamic movement of the elastic body 21 can be seen and enjoyed when the elastic body 21 is restored. .

[Modification]
In the above-described play equipment 1 using crackers, the cracker support plate 4 is configured to support a plurality of crackers 10, and includes the same number of elastic bodies 21 and in-process yarns 8 as the crackers 10. Thus, although it can comprise so that the several cracker 10 may be sounded with one cracker utilization play equipment 1, the cracker utilization play equipment 1 may be comprised so that the cracker 10 which can be mounted | worn may be single, and can be equipped. You may comprise so that the cracker 10 may become two or more larger than two. Below, the modification of the cracker utilization playground equipment 1 is demonstrated.

(Modification 1)
First, the modification 1 of the cracker utilization playground equipment 1 is demonstrated. FIG. 4 is a plan view showing Modification 1 of the play equipment using crackers. As shown in FIG. 4, the cracker utilization play equipment 1 according to the first modification can be equipped with four crackers 10. For this purpose, the cracker support plate 4 includes four cracker support holes 41, four conduction holes 42, and four second connecting portions 43, and four elastic bodies 21 are fixed to the base 2. The ends are fixed. At the free end of each elastic body 21, one end of the in-process yarn 8 passing through the tubular member 52 of the light guide body support portion 5 while making contact with the light guide body 6, and the pull string of the cracker 10 are respectively provided. It is fixed. In the cracker-use playground equipment 1 having such a configuration, when the igniting body 6 supported by the igniting body supporting portion 5 is ignited, each in-process yarn 8 is burned out by the fire and heat, and each elastic body 21 is elastically recovered. The free end is displaced and each cracker 10 sounds. Here, since the four in-process yarns 8 are burned out in order from the one arranged in the cylindrical member 52, the four crackers 10 are connected to the in-process yarn 8 arranged in the upper side in the cylindrical member 52. The elastic body 21 sounds one after another in order from the one with the drawstring connected thereto. If the four in-process yarns 8 are arranged at the same height in the cylindrical member 52, the four crackers 10 can be sounded almost simultaneously.

(Modification 2)
Then, the modification 2 of the cracker utilization play equipment 1 is demonstrated. FIG. 5 is a perspective view showing Modification Example 2 of the cracker-use playground equipment, and FIG. 5 is a perspective view showing Modification Example 2 of the cracker-use playground equipment. As shown in FIGS. 5 and 6, the cracker utilization play equipment 1 according to the second modification can be equipped with four crackers 10. For this purpose, the cracker support plate 4 includes four cracker support holes 41, two conduction holes 42, and two second connecting portions 43, and two elastic bodies 21 are fixed to the base 2. The ends are fixed. At the free end of each elastic body 21, one end of the in-process yarn 8 that passes through the cylindrical member 52 of the igniting body support portion 5 while making contact with the igniting body 6, and the pull string of the two crackers 10 And are fixed to each. In the cracker-use playground equipment 1 having such a configuration, when the igniting body 6 supported by the igniting body supporting portion 5 is ignited, each in-process yarn 8 is burned out by the fire and heat, and each elastic body 21 is elastically recovered. The free end is displaced and each cracker 10 sounds. Here, the two in-process yarns 8 are burned out in order from the one arranged on the upper side in the cylindrical member 52. Therefore, first, the elastic body 21 connected to the in-process yarn 8 arranged on the upper side in the cylindrical member 52. The two crackers 10 to which the drawstrings are coupled to each other ring, and then, the remaining 2 to which the drawstrings are coupled to the elastic body 21 connected to the work thread 8 disposed on the lower side in the cylindrical member 52. Each cracker 10 sounds. If the two in-process yarns 8 are arranged at the same height in the cylindrical member 52, the four crackers 10 can be sounded almost simultaneously.

  Modification 1 including a plurality of elastic bodies 21 and work threads 8 that are the same as a plurality of crackers 10, and Modification 2 including a plurality of crackers 10, and a plurality of elastic bodies 21 and work threads 8 that are less than that, respectively. As can be seen from the above, even the cracker-use playground equipment 1 that can be equipped with the same number of crackers 10 can have a different number of elastic bodies 21 and in-process yarns 8. That is, the number of crackers 10 that can be attached to the cracker-use playground equipment 1 and the number of elastic bodies 21 and in-process yarns 8 do not necessarily have to match. If the number of elastic bodies 21 and in-process yarns 8 included in the cracker-use playground equipment 1 is reduced relative to the number of crackers 10 that can be mounted on the cracker-use playground equipment 1, it is possible to suppress the enlargement of the device and the number of parts. It becomes possible to provide products at a lower price.

[Example of combination]
Other play equipment can be combined with the above-described play equipment 1 using crackers. Below, the example which combined the pop-up message board is demonstrated. FIG. 7 is a side view showing an example in which a pop-up message board is combined with a play equipment using crackers. FIG. 8 is a side cross-sectional view for explaining the operation of the pop-up message board. b) shows after pop-up.

  As shown in FIGS. 7 and 8A, the cracker-use playground equipment 1 includes a pop-up message board 70 on the back side of the supporting sheet 3 in FIG. 7. This pop-up message board 70 rises slowly after the cracker 10 rings.

  The pop-up message board 70 includes a support 71 erected on the base 2, a vertically extending support cylinder 72 connected to the upper end of the support 71, and a shaft-shaped base portion 76 a slidable inside the support cylinder 72. An inserted message base 76, a message board 75 attached to the upper part of the message base 76, and a spring 73 mounted on the support cylinder 72 are provided.

  The message stand 76 integrally includes a base portion 76a inserted into the support cylinder 72, a flange portion 76b provided at the upper end of the base portion 76a, and a work thread fixing portion 76c provided around the flange portion 76b. I have. The flange portion 76 b has an outer diameter larger than the outer diameter of the support cylinder 72, and the downward movement of the message base 76 is restricted when the lower surface of the flange portion 76 b and the upper end surface of the support cylinder 72 abut. The upper end of the spring 73 is in contact with the lower surface of the flange portion 76b, the lower surface of the spring 73 is in contact with the stepped surface of the support column 71 and the support cylinder 72, and the spring 73 is in a compressed state before the pop-up ( FIG. 8 (a)).

  The in-process yarn fixing portion 76 c provided in the message base 76 is a hole to which the in-process yarn 74 can be tied, and is provided in two places in the message base 76. On the other hand, the cracker support plate 4 is provided with guide bodies 44, 44 through which the work thread 74 passes according to the number of work thread fixing parts 76 c, and the work thread is provided on the tubular member 52 of the igniter support part 5. Insertion holes 58 and 58 through which 74 is in contact with the igniting body 6 are formed. The guide body 44 is at a lower position than the in-process thread fixing portion 76 c of the message base 76, and the insertion holes 58 and 58 formed in the tubular member 52 are at a higher position than the guide body 44.

  As shown in FIG. 8A, in the pop-up message board 70 before pop-up, one end of the in-process yarn 74 is fixed to one of the in-process yarn fixing portions 76c of the message base 76, from which one guide body 44, cylinder The other end is fixed to the other of the in-process yarn fixing portion 76c through the insertion holes 58 and 58 formed in the shaped member 52 and the other guide body 44. The in-process yarn 74 is tensioned so that the spring 73 is compressed to a position where the flange portion 76b of the message base 76 and the support cylinder 72 come into contact with each other. The in-process yarn 74 is in a position lower than the in-process yarn 8 for ringing the cracker 10 in the cylindrical member 52 and burns out after the in-process yarn 8.

  Then, when the igniting body 6 of the cracker-use playground equipment 1 is ignited, the igniting body 6 burns, the in-process yarns 8, 8 are burned out, the crackers 10, 10 sound, and the in-process yarn 74 is subsequently burned out. Then, the message base 76 is released from the tension of the work thread 74, the compressed spring 73 starts to stretch, and the message board 75 starts to rise integrally with the message base 76 as shown in FIG. Here, if grease that provides sliding resistance is applied to the inner periphery of the support cylinder 72 and the outer periphery of the base portion 76a of the message base 76, the message board 75 rises relatively slowly over time. Note that the message board 75 after the pop-up is preferably positioned higher than the tubular member 52 of the igniter support 5 so that the message is not hidden by the igniter support 5.

  Further, in order to prevent the pop-up message board 75 from being hidden by the igniter of the igniting body 6, for example, the cracker-use playground equipment 1 is configured so that the igniting body 6 after combustion falls into the column 3. You can also. FIG. 9 is a side cross-sectional view for explaining a modification of the igniting body support, in which FIG. 9 (a) shows the igniting body before combustion, and FIG. 9 (b) shows the igniting body after combustion.

  In the example shown in FIG. 9A, the support column 3 of the cracker-use playground equipment 1 is formed of a cylindrical body, and the cylindrical member 52 of the igniting body support portion 5 is fixed to the upper end of the support column 3. A protrusion 31 that protrudes toward the inner periphery is formed on the inner periphery of the support column 3. The inner diameter of the projecting portion 31 is larger than the outer diameter of the conducting body 6 so that the conducting body 6 can pass through the inner periphery of the projecting portion 31. On the other hand, the handle portion of the igniter 6 is made of a material that melts with the heat of the igniter 6 such as wax or paper or burns with fire, and has an outer diameter larger than the inner diameter of the protrusion 31 of the column 3. A flange 61 is attached. When the igniting body 6 is inserted into the cylindrical member 52 from above, the lower surface of the flange 61 comes into contact with the upper surface of the protrusion 31 of the support column 3 and the igniting body 6 is supported.
