Two C-shaped hooks are respectively fixed to the two ends of the tube unit. Each hook includes a first connection portion. Two plates are respectively connected to the two end parts. Each plate includes a first section, a second section and a third section. The second section is formed inclinedly between the first and third sections. The third section of each plate is fixed to the end part corresponding thereto. The first section of each plate is removably engaged with the first connection portion of the hook by sliding the end part. The first section includes a first recess and a second recess. The second recess is located close to the second section and includes a recessed reinforcement which reinforces a portion between the first and second sections.",
  "claims": [
    "1. An adaptor bar comprising: a tube unit including an inner tube and an outer tube, the inner tube having a first end thereof slidably inserted into a first end of the outer tube; two end parts respectively connected to two respective second ends of the inner tube and the outer tube; two hooks respectively fixed to the two respective second ends of the inner tube and the outer tube, each hook having a first connection portion; two plates respectively connected to the two end parts, each plate having a first section, a second section and a third section, the second section formed between the first and third sections, an axis of the second section being inclined relative to two respective axes of the first and third sections, the third section of each plate being fixed to the end part corresponding thereto, the first section of each plate being removably engaged with the first connection portion of the hook corresponding thereto, the first section having a first recess and a second recess formed to a first side thereof, the second recess located close to the second section and including a recessed reinforcement area located around the second recess so as to reinforce a portion between the first and second section.",
    "2. The adaptor bar as claimed in claim 1, wherein a first sleeve is mounted to an outside of each of the hooks, a second sleeve is mounted to an outside of each of the plates.",
    "3. The adaptor bar as claimed in claim 1, wherein the first and second recesses and the reinforcement recessed area of each plate are made by way of pressing.",
    "4. The adaptor bar as claimed in claim 1, wherein a protrusion is formed from a second side of each of the plates and located corresponding to the reinforcement recessed area.",
    "5. The adaptor bar as claimed in claim 1, wherein two curved ridges protrude from an outer periphery of the reinforcement recessed area of each plate."

  "description_excerpt": "The present invention relates to an adaptor bar of a bicycle, and more particularly, to a slidable plate to close the hooked end of the adaptor bar.\n\nOne of the conventional bicycle racks known to applicant includes at least one support part which is designed to support the bicycle top tube so as to load the bicycle to a bicycle rack. However, a lady's bike does not have the top tube so that an adaptor bar is used to perform as the top tube. Generally, the adaptor bar includes two hooks connected to two ends of the adaptor bar. Each hook includes a plate which is used to form an opening or to close the opening relative to the hook. Each plate is connected to an end part that is slidably connected to a tube. When the two end part is slid along the tube, the plate is moved with the end part, the bicycle head tube and seat post can be inserted into the hook via the opening. When returning the end part, the plate is moved to close the opening so that the adaptor bar is installed to the bicycle. Therefore, the adaptor bar plays the role as the top tube. The distance between the two hooks can be adjusted by the above movement of the end parts to allow the two hooks to reach the head tube and the seat post.\n\nAs shown in FIG. 1, the plate 60 used to the adaptor bar mentioned above is an elongate plate and includes two holes 62, 63 so that screws (not shown) extend through the two holes 62, 63 so as to connect the plate 60 to the end part. However, it is noted that the hole 63 is located very close to the inclined section 61 of the plate 60, and the hole 63 reduces the strength of the plate 60 close to the inclined section 61.",
