The present invention relates to a repair tool, particularly to a tire repair kit for a bicycle.
As riding a bicycle, to prevent one of tires of the bicycle from being broken by pressing a sharp objector, many riders will carry tire repair kits, such as tire repair needle and tire patch on them to repair the broken tire. to insert the tire patch into the broken hole in the broken tire, a tip end of the tire repair needle is formed as a branch structure to form a gap for holding the tire patch in the gap between the branch structure. The tire patch is inserted into the broken tire via the broken hole by the tip end of the tire repair needle, and the tire repair needle is pulled out from the tire. When the tire repair needle is pulled out from the tire, the tire patch is detached from the branch structure and keeps in the broken hole.
However, when the conventional tire repair kit is in use, the branch structure on the tip end of the conventional tire repair needle has a diameter to cause a secondary damage or many damages to the broken hole in the broken tire. Thus, air loss from the tire will be increased, and the tire patch will not completely seal the broken hole. In addition, the tire repair needle and the tire path are used as needed, so to carry and store the conventional tire repair kit is trouble for the user. Therefore, a tire repair kit for preventing from causing a secondary damage to a broken tire and for being conveniently stored is an improved target in the industry.
To prevent from causing a secondary damage to a broken hole of a broken tire and to solve a problem of inconveniently being stored due to a size of the conventional tool, the present invention provides a tire repair kit having two ends including a guiding tip end having a diameter gradually decreasing to form a tip head and a connection end adapted to connect with a tool and capable of being axially detaching from the tool, wherein a receiving space defined between the guiding tip end and the connection end adapted to hold a tire patch inside.
Wherein, the tire repair kit is shaped as a column, and the connection end has a connection structure formed axially on the connection end, and the connection structure is a circular hole, a rectangular hole, a hexagonal hole, or a polygonal hole.
Wherein, a holding hole is defined diametrically in the tire repair kit, and the receiving space is defined in the holding hole.
Wherein, two holding holes are defined diametrically in the tire repair kit, and the receiving space is defined in the two holding holes.
Wherein, a notch is formed through a periphery of the guiding tip end to form the guiding tip end as a fork structure, the fork structure includes a first tip head portion and a second tip head portion, and the notch is formed between the first tip portion and the second tip portion.
Wherein, the notch extends axially from tip head toward holding holes and communicating with an adjacent one of the holding holes.
Wherein, a notch is defined in a side of the tip head and communicating with an adjacent one of the holding holes, the guiding tip end is divided into a first tip head portion having a long length and a second tip head portion having a short length shorter than the long length of the first tip head portion, and a stop portion is formed on the second tip portion and protruding toward the receiving space.
Wherein, a direction in which the notch defined through the tire repair kit is same as a direction in which the holding hole defined through the tire repair kit.
Wherein, a neck structure is formed on an outer surface of the tire repair kit and is adjacent to the connection end, and the connection end having a diameter smaller than a diameter of the outer surface to form a flange between the outer surface and the connection end.
Wherein, the tire repair kit is made of a biodegradable material.
When the tool in accordance with the present invention is in use, the connection end of the tire repair kit is connected with a tool, and a tire patch is held in the receiving space. The guiding tip end is inserted into a broken hole in a broken tire by the hand-held tool. When the tire repair kit extends through and expand the broken hole, the broken hole closely wraps around the periphery of the tire repair kit. With the inserting direction of the tire repair kit and pressing pressure provided by the wrapping force of the broken hole, two ends of the tire patch extending out of the receiving space are bent toward the connection end. When the tire repair kit is all inserted through the broken hole, at least a part of two ends of the tire patch and at least a part of the hand-held tool are still held in the broken hole. Then, the hand-held tool is pulled out from the broken hole in the broken tire and is detached from the connection end of the tire repair kit. At this time, the tire repair kit is held in the tire, and the tire patch extends out of the broken hole. Accordingly, the broken tire is repaired.
The tire repair toll in accordance with the present invention has the following advantages:
1. The tire repair kit has a small volume and a light weight, so the tire repair kit with a tire patch with a small volume is easily stored. A conventional tire repair needle is not needed, and therefore the storage space for the tire repair kit is reduced.
2. With the arrangement of the connection end and the neck structure, the tire repair kit can be applied to be connected with many kinds of hand-held tools in the market and is versatile in use.
3. The guiding tip end with a notch can be deformed by the pressing pressure of the broken hole, and the diameter of the guiding tip end can be decreased to prevent the broken hole is over-expanded to cause secondary damage to the broken hole. Thus, the broken hole can be completely sealed by the tire patch.
4. With the arrangement of multiple receiving spaces, position of the tire patch can be determined by the size of the broken hole.
