Description

[Detailed description of the invention] The present invention relates to the invention of a stopper mechanism for a sliding door, which alleviates the impact when opening the sliding door and prevents the operator's fingertips from being pinched. Moreover, it is an attempt to provide a stopper mechanism with high durability.

Sliding doors are a type of door that can be opened at any time to achieve the purpose of passage or ventilation, and have been widely used in the past.
When the sliding door is opened, an impact is made against the door stop surface such as the pouring material, and therefore a strong impact sound is generated when the sliding door is opened. Particularly in recent years, door wheels and door rails have been widely adopted, and light opening and closing has come to be respected, and the impact noise generated when the doors are opened becomes louder. In addition, when opening this sliding door, the operator often holds the vertical stile of the sliding door to be opened, so when opening the door, it is necessary to place the fingertips of the operator between the sliding door and the door stop surface. There is a high risk of getting caught. The present invention has been devised after repeated studies in view of the above-mentioned circumstances, and the implementation thereof is specifically explained as shown in the attached drawings. In the case where sliding doors 10, 10 are provided in a double-sliding type, groove-shaped recesses 2 as shown in Figs. The base of a stopper 3 protruding at least half of the total height toward the opposite sliding door as described above is fitted into the recess 2, and a recessed tightening seat 3a is formed in the center of the stopper 3. The fixing seat 3a is fixed to the bottom of the recess 2 by means of a stator 4.

In the illustrated example, seats 11, 11 are provided oppositely on the doorstop surface of the vertical stile 1 as described above, and doorstops 15, 15 each having a box-shaped cross section are provided on both sides of these seats 11, 11. A vertically installed door stop member 5 is attached, and an elastic tongue piece 5 is provided opposite to the central part of the door stop member 5.
A vertical frame member 20 such as a support that is fixed to the vertical stile 1 by a stopper 14 at the bottom of the groove formed in the portions a and 5a, and to which the sliding door 10 is joined.
A joining member 7 having joining portions 7a having an arcuate cross section is attached to both sides thereof, and the joining portions 7a are connected to the elastic tongues 5a, 5a.

According to the present invention as described above, when the sliding door 10 is pulled as indicated by the arrow P shown in FIG. It is clear that the impact of the front end of the sliding door on the vertical frame member 7 can be appropriately prevented, that is, the generation of noise due to the impact can be prevented, and the operator etc. can avoid the vertical frame member 7. 7, and the stopper 3 has its base in the recess 2 of the vertical stile 1.
Since it is fitted inside and fixed by the stator 4, its attachment condition is extremely stable and strong, and it will not come out of the recess 2 even if subjected to a considerable impact, that is, it will have a favorable stopper action. This is a highly effective idea in practical terms because it can be secured for a long period of time and the sliding door can be opened freely without having to be particularly careful when operating the sliding door.

In addition, the stopper 3 according to this invention is a sliding door 1.
If the sliding door 10 to which the stopper 3 is attached, as shown in this cross section in FIG. As shown in Fig. 2, by providing stoppers 3, 3 on both sliding doors 10, 10, the stopper 3 that is stopped and the stopper that slides can be connected to the vertical stile of the sliding door to prevent impact. 3 together act to prevent the occurrence of impact, and the above-mentioned stable effects can be achieved.
