Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for protecting the front and rear edges of a unicycle saddle.

(Prior art) As this type of conventional technology, for example,
Some of these are disclosed in Japanese Utility Model Publication No. 23749 and Japanese Utility Model Application Publication No. 164476/1983.

(Problem that the invention seeks to solve) Generally, for beginners to learn how to ride a unicycle, they will have to overturn the unicycle dozens or even hundreds of times. When a unicycle falls, the body of the unicycle is often slammed violently against the ground in order to prioritize physical safety, and as a result, the front or rear edge of the saddle is often damaged.

For this reason, the above-mentioned Utility Model Publication No. 58-23749 (former),
Alternatively, a saddle reinforcement or protection device as shown in Utility Model Application Publication No. 60-164476 (the latter) has been proposed, but the former has bolt holes for mounting the saddle guard drilled in the saddle base, and the saddle guard Since the bolt insertion portion of the unicycle protrudes like a tongue, there is a problem in that the saddle base and the saddle guard are easily damaged when the unicycle falls and a strong impact is applied to the saddle.

In addition, with the latter, the saddle top and guard material are fixed to the base at the same time by bending the clasp, so if this is repeated and subjected to impact from various angles, the unscrewed guard may become damaged. To replace this saddle guard, which can come off the saddle and is the most susceptible to damage, the saddle must be disassembled, and the clasp must be bent back, which may cause the clasp itself to break. There was a problem that it could not be easily handled by amateurs.

(Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, tongue pieces protruding from a plurality of locations on the upper edge of the curved strip are bent inward, Further, bend it downward, provide a screw hole in the tongue piece to form a mounting tongue piece, and bend the tongue pieces protruding from the upper edges of the strips on both sides of these mounting tongue pieces inward. forming a locking piece, forming a reinforcing plate by providing rivet holes in a band plate facing the locking piece, and applying the reinforcing plate to the inside of the front and rear edges of the base frame of the unicycle saddle, respectively; The base frame and the reinforcing plate are fixed with rivets through the rivet holes, and the base frame is covered with a covering material forming the top of the saddle.The U-shaped cross section has a curved groove into which the front and rear edges of the saddle are fitted. The inner edge of the member has a bolt insertion hole facing the screw hole, and a recess is provided in the center of the lower surface of the member to form a guard, and the guard is fitted to the front and rear edges of the saddle from below, respectively. A protection device for a unicycle saddle is constructed by screwing a bolt into the screw hole through the bolt insertion hole.

(Function) As mentioned above, in this invention, reinforcing plates are attached to the front and rear of the saddle, and a guard is fitted to this attached part, and bolts are screwed into screw holes provided in the reinforcing plate to fix the saddle. By doubly reinforcing the saddle, the durability of the front and rear parts of the saddle can be further improved. That is, since the base frame of the present invention is not provided with any mounting holes, it is possible to eliminate the reduction in strength due to the guard mounting holes and to prevent damage caused by the holes.

Furthermore, the guard of the present invention can be easily installed and removed using screws, so even an amateur can easily replace it. Furthermore, since the lower surface of the guard of the present invention has a recessed part, even small children can grasp this part to maintain balance when riding.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. In the figure, 1 is the vertical pipe of the unicycle, and 2 is the vertical pipe 1.
Base frame of unicycle saddle connected to 3
4 is a cushioning material provided on the base frame 2, and 4 is a covering material (leather) forming the top of the saddle.

In this embodiment, as shown in detail in FIG. 4, tongues protruding from multiple locations (two locations in this embodiment) of the upper edge 5a of the curved iron strip 5 are directed inward. The mounting tongues 6 are formed by bending the tongues, and further bending them downward, and providing screw holes 6a in the tongues to form the mounting tongues 6. The protruding tongue piece is bent inward to form a locking piece 7, and this locking piece 7
A reinforcing plate 8 is formed by providing rivet holes 5b in the band plate 5 facing the unicycle saddle, and this reinforcing plate 8 is applied to the inside of the front and rear edges of the base frame 2 of the unicycle saddle, respectively, as shown in FIGS. 1 and 2. At the same time, the base frame 2 and the reinforcing plate 8 are fixed with rivets 9 through the rivet holes 5b, and the base frame 2 is covered with a covering material 4 forming the top of the saddle.
The covering material 4 bonded to the inner surface of the saddle is held down by the locking piece 7 as shown in FIG. Bolt insertion hole 10b facing 6a
and a recess 1 in the center of the lower surface of this member.
0c is provided to form a guard 10 made of synthetic resin,
This guard 10 is fitted onto the front and rear edges of the saddle from below, respectively, and the bolt 11 is screwed into the screw hole 6a through the bolt insertion hole 10b to constitute a protection device for a unicycle saddle.

(Effect of the invention) As described above, in the present invention, the reinforcing plate 8 is attached to the front and rear of the saddle, the guard 10 is fitted to this attached part, and the bolt 11 is connected to the screw provided on the reinforcing plate 8. It is fixed by screwing into the hole 6a: Since the saddle is double reinforced, the durability of the front and rear parts of the saddle can be further improved. In other words, the base frame 2 of the present invention
Since no guard mounting hole is directly provided in the guard mounting hole, it is possible to eliminate the reduction in strength due to the guard mounting hole and to prevent damage caused by the hole.

Furthermore, the guard 10 of the present invention can be easily installed and removed using screws, so even an amateur can easily replace it. Furthermore, since the lower surface of the guard 10 of the present invention is provided with a concave portion 10c, even small children can easily grasp this portion to maintain balance when riding the vehicle.
