Description

  The present invention relates to a door stop, and more particularly to an improvement of the door stop for stopping a sliding door at an arbitrary position.

  Conventionally, when a plurality of sliding doors move on one rail, in order to limit the moving range of the sliding door, a stopper is provided on the upper surface of the rail, and the door wheel is provided rotatably on the upper surface of the sliding door. The door stop which contacts the said stopper and stops a sliding door in arbitrary positions is used (for example, refer patent document 1).

However, if the door wheel disposed on the upper surface of the sliding door is brought into contact with the stopper, the position where the door wheel is disposed is limited to the upper surface end of the sliding door. Moreover, in the case of the sliding door which arrange | positions a doorwheel in the lower surface of a sliding door and moves the rail laid on the floor surface, a doorwheel cannot contact | abut to a stopper.
Therefore, as shown in FIG. 8 to FIG. 9, the sliding door 4 is made up of the abutting member 41 disposed at the upper part of the door end of the sliding door 4 and the fixing member 42 having the elastic body 43 against which the corresponding contacting member 41 abuts. A door stop 40 that stops at an arbitrary position is widely used.

  The door stop 40 has a fixing member 42, an opposed standing surface 42a, 42a, a bottom surface 42b connecting the standing surface 42a, and an attachment surface in which the upper end of the standing surface 42a extends in an L shape. 42c, and is fixed to the upper frame 2a of the sliding door frame member 2 that guides the upper part of the sliding door 4 with a fastening member such as a screw through a hole opened in the mounting surface 42c, and is attached to the outer surface of the standing surface 42a. The plate-like elastic body 43 is stuck with a double-sided adhesive tape or an adhesive so as to reduce the impact when the contact member 41 disposed on the sliding door 4 contacts the fixed member 42.

JP-A-8-232535

By the way, the door contact 40 is configured such that the contact member 41 disposed on the sliding door 4 is fixed to the fixing member 42 due to wear due to aging of the door wheel disposed on the lower surface of the sliding door 4 or installation error of the sliding door frame member 2. In some cases, the elastic body 43 may be in contact with the lower side of the standing surface 42a.
In this case, there is a problem that the elastic body 43 is easily dropped due to an impact when the contact member 41 contacts the fixed member 42.

  In view of the problems of the conventional door stop, the present invention provides a door stop in which the elastic body does not fall out regardless of the contact portion between the contact member and the elastic body attached to the fixing member. With the goal.

  In order to achieve the above object, the door stop of the first invention is a door stop comprising a contact member disposed on an upper portion of a sliding door and a fixing member having an elastic body with which the contact member contacts. The fixing member includes an upright surface facing each other and a bottom surface connecting the upright surfaces, and an opening is formed in the upright surface, and a protruding portion protruding from the opening is provided. An elastic body having an abutting portion that abuts on the inner side of the surface is disposed on the fixing member.

  In this case, the contact portion of the elastic body can protrude from the side opening of the fixing member.

According to the door stop of the present invention, the fixing member is configured to include an upright surface facing each other and a bottom surface connecting the upright surface, and an opening is formed in the upright surface. Since the elastic body in which the protruding portion and the contact portion that contacts the inside of the standing surface are arranged on the fixing member, the contact portion and the bottom surface of the elastic body are the standing surface and bottom surface of the fixing member. And the elastic body is held by the fixing member in a state where the edge of the protruding portion of the elastic body is locked to the edge of the fixing member.
Therefore, even if the abutting member abuts on the lower side portion of the elastic body arranged on the fixing member, it is possible to provide a door stop in which the elastic body does not fall off from the fixing member.

  In this case, when the contact portion of the elastic body protrudes from the side opening of the fixing member, the contact member of the sliding door is applied not only to the end surface of the protrusion portion of the elastic body but also to the end surface of the contact portion. The sliding door can be used as a door to a partition that may be moved along a rail laid in a T-shape or a cross shape.
