Description

  The present invention relates to a metal handle attached to an opening / closing member such as a door, a door of furniture, or a door of furniture, and more particularly to an improvement of a metal handle in which a grip portion and a support column portion are integrally formed.

  Conventionally, various handles comprising a substantially vertically long grip portion gripped by a person and strut portions formed at both ends thereof and attached to an opening / closing member have been proposed (see Patent Documents 1 to 3).

  One conventional handle has a structure in which a grip part and a support part are formed from separate members, and these members are processed in various ways or parts are assembled to these members and assembled together (Patent Literature). 1). However, such a structure requires a large number of members and parts, so that processing and assembly are troublesome, and there is a drawback that the handle cannot be manufactured at low cost.

  Another prior art handle consists of two L-shaped core members that are spaced apart vertically and a metal plate-shaped wrapping member that wraps the core member between these core members. (See Patent Document 2). The handle with this structure has a drawback that the work of wrapping the metal plate is particularly troublesome, and it is difficult to wrap the metal plate-shaped wrapping member so that no wrinkles occur in the core member, resulting in a poor appearance of the product. .

  Still another prior art handle consists of a single pipe formed by bending both ends into an L shape (see Patent Document 3). Since the handle of this structure forces the pipe to bend so that its cross section is crushed, the bending radius must be increased, and similarly, a padding is inserted into the grip portion and the strut portion to maintain strength. However, the operation of inserting the stuffing into the grip portion is particularly troublesome and has the disadvantage of low manufacturing efficiency.
