JP-A-8-68248

However, in the sub-block device of Patent Document 1, when the door hits one end of the stopper when the sliding door is opened and the stopper receives a force, the force received by the stopper causes the stopper to pivot on the case. There is a problem that the force concentrates on only one part and is easily damaged because only the shaft part is received.
On the other hand, in order to increase the strength of the sub-block device, the use of high-strength components increases the cost, and when the size is increased, the appearance of the entire sliding door is impaired.

  Accordingly, an object of the present invention is to provide a sublock device that is small in size and low in cost and has high strength, and a sliding sash including the sublock device.

The invention according to claim 1 includes a stopper, a case, and a shaft. The case has a stopper storage portion that is open to the indoor side and is formed by vertical and horizontal prospective walls. It has upper and lower prospective surfaces facing the prospective wall, is arranged in the stopper storage part, the shaft penetrates the middle position in the sliding door opening and closing direction of the case and stopper vertically, and the case and stopper are integrated. The upper prospective surface and the lower prospective surface of the stopper have a locking groove at a position on one side of the sliding door opening / closing direction with respect to the shaft and at a position on the outdoor side of the indoor-side finding surface of the stopper. And the outer groove wall and the shaft groove wall, and the upper and lower prospective walls of the case are positioned on one side of the sliding door opening / closing direction with respect to the stopper. Has a locking projection that enters the locking groove The other end of the stopper in the sliding door opening / closing direction is submerged in the case so that when the one end protrudes from the case to the indoor side, the one end of the stopper becomes a shoji contact portion. The sub-block device is characterized in that the stop protrusion comes into contact with an outer corner of the locking groove.

  According to a second aspect of the present invention, in the first aspect of the present invention, the upper prospective surface and the lower prospective surface of the stopper have a guide groove that is continuous with the locking groove and opens in one of the side walls of the stopper. The opening of the guide groove is used as an insertion opening for the locking projection when the stopper is assembled in the case.

  According to a third aspect of the present invention, in the sub-block device according to the first or second aspect, the locking protrusion of the case is located on the indoor side of the shaft.

  A fourth aspect of the present invention is a sliding sash characterized in that the sub-block device according to any one of the first to third aspects is provided on an upper side or a lower side of a sliding door.

According to the first aspect of the present invention, when the one end of the stopper protrudes to form a shoji contact portion, the door hits the one end of the stopper and the one end of the stopper exerts a force. When received, the force received by the stopper is received at two locations of the shaft and the locking projection. Accordingly, it is possible to prevent the force received by the stopper from being concentrated at one place and being damaged.
Since the force received by the stopper does not concentrate in one place, it is not necessary to use a material having a particularly high strength, so that the manufacturing cost can be reduced.
Since the stopper is pivotally mounted in the case by the shaft, the groove is formed in the stopper, and the projection is formed on the case, it is small in size, simple in configuration, and easy to assemble.
When the sliding door hits one end of the stopper (the shoji contact part), a moment force that tries to rotate the stopper around the shaft acts, and the locking projection has a circle with a radius between the shaft. A tangential force is received from the outdoor groove wall, and a reaction force from the shaft is received from the outdoor groove wall forming the corner and the axial groove wall. Although the moment force and the reaction force of the shaft cause a slight shift in the position at which they act depending on the component accuracy and assembly accuracy, the locking projection comes into contact with the outdoor corner in the locking groove. Even if there is a slight shift in the direction of the force acting on the groove, the groove wall forming the corner can abut against the locking projection from the direction of the rotational moment and the direction of the reaction force of the shaft. Without requiring an assembly system, the shaft and the locking projection can receive the impact in a distributed manner.

  According to the second aspect of the present invention, the effects described in the first aspect can be achieved, and the stopper can be incorporated into the case by inserting the locking protrusion from the opening of the guide groove, so that the assembly is easy. .

  According to the invention described in claim 3, when the other side end portion in the sliding door opening / closing direction of the stopper is submerged in the case, the locking projection is formed with the shaft. Compared with the case where it is the same or located on the outdoor side of the shaft, the projecting dimension of the one end portion of the stopper which is the shoji contact portion can be increased. In other words, the expected size of the stopper can be reduced in order for the shoji contact portion to obtain a predetermined protruding dimension, and the sub-block device can be reduced in size.

  According to the invention described in claim 4, it is possible to provide a sliding sash that exhibits the operational effects described in any one of claims 1 to 3.
