We provide locks that can be applied to other models. In a lock having a main body portion 10 in which a pressure contact portion 9a for a door is movably provided and an attachment portion of the main body portion, a removable auxiliary pressure contact member 9 is attached to the pressure contact portion of the main body portion. A lock that is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a lock which can prevent opening and closing by pressing a sash door or the like housed in a rail or a sash window or the like housed in a window frame.

[0002]

[Prior art]

 Conventionally, a lock is known and has a structure shown in FIG. Reference numeral 1 is a main body portion, and 2 is a pressure contact portion attached to the main body portion and capable of coming in and out in the direction of the sash. Reference numeral 3 is a grip for moving the press-contact portion in and out. An eccentric cam 4 is integrally attached to the grip, the cam rotates following the rotation of the grip, and the cam engages with an engaging portion provided in the pressure contact portion to move the pressure contact portion in and out. Move as possible. Reference numeral 5 denotes an attachment portion provided on the main body or a separate member integrally fixed to the main body. The mounting portion is fitted into the fixed portion, for example, in the drainer of the sash rail 6 and fixed by screws. 7 and 8 are also referred to as inner and outer sashes and sash doors. 2a shows a state in which the press contact portion is extended to press the outer sash.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional structure has the following problems because the main body 1 and the mounting portion 5 are integrally fixed at a predetermined position. When pressing the outer sash, the pressing part must be extended and the grip rotation operation is troublesome. In addition, when the sash door presses against the sash door with a long protrusion, the pressing force applied to the cam increases, and if the cam slightly rotates in the opposite direction, it will not come into pressure contact and the effect of the locking lock will be lost.

[0004]

[Means for Solving the Problems]

 The present invention has the following features. Details have been described in Examples and the like described later. "In a lock having a main body portion in which a pressure contact portion is movable with respect to a door and an attachment portion of the main body portion, a removable auxiliary pressure contact member is provided in the pressure contact portion of the main body portion. The lock that says. "

[0005]

[Action]

 In the lock of the present invention, although the press contact portion can be expanded and contracted, the auxiliary press contact member is further provided so as to be detachable, so that the distance between the position of the press contact portion of the sash door and the position of the press contact portion of the lock lock is reduced. If the length is long, you can set a short distance between the pressure contact part and the pressure contact part by attaching an auxiliary pressure contact member suitable for that length, which makes it easy to rotate the grip and increase the pressure contact force. The function as a lock can be fully exerted. In addition, the above-mentioned merits can be exhibited corresponding to each model. Furthermore, if an auxiliary pressure welding member having a surface material suitable for the pressure welding portion is prepared, the pressure welding portion will not be damaged. Therefore, the types of locks can be reduced, and the production cost and management cost can be reduced.

【Example】

 1 to 3 are a plan view, an AA sectional view, and a bottom view showing an embodiment of an auxiliary pressure contact member used for a lock of the present invention. Reference numeral 9 is an auxiliary pressure welding member made of synthetic resin or aluminum die cast. Reference numeral 9a is a press contact portion, and 9b is an insertion concave portion.

FIG. 4 shows a plan view of the auxiliary pressure contact member 9 mounted on the pressure contact portion of the lock. Reference numeral 10 is a main body portion, 11 is a grip, and 12 is a pressure contact portion. The eccentric cam rotates in the main body due to the rotation of the grip, and the cam moves in the in-and-out direction while the drive unit integrated with the pressure contact unit is engaged. Such a configuration is similar to the conventional one.

The pressure contact portion 12 is formed in a protrusion shape on the upper side, and the insertion recess 9b of the auxiliary pressure contact member is detachably fitted to the protrusion portion. Therefore, the pressure contact member extends by the length of the auxiliary member.

FIG. 5 shows an actual mounting state in which the lock of FIG. 4 is applied to the sash. Reference numeral 10a denotes a mounting portion, which is fixed to the sash rail 13 with screws. When the grip 11 is rotated, the auxiliary pressure contact member 9 moves in the sash direction together with the pressure contact portion 12. The sash 14 is pressed and fixed.

FIG. 6 is a plan view showing another embodiment of the auxiliary pressure contact member 15 of the present invention. In contrast to the one in Fig. 1, the length of the pressure contact part is shortened. For example, if two types of auxiliary pressure contact members are prepared, it is possible to cope with three different length dimensions, including the case where they are not used. It will be understood that the shape of the auxiliary pressure contact member of the present invention is not particularly limited, and any shape and structure can be integrated with the pressure contact member in the detachable state. Therefore, it is possible to change the design of each species.

[0011]

【effect】

 According to the present invention, in the lock, the press contact portion can be expanded and contracted, and the auxiliary press contact member is further provided detachably, so that the position of the press contact portion of the sash door and the position of the press contact portion of the lock can be set. If the distance is long, the distance between the pressure contact part and the pressure contact part can be set short by attaching the auxiliary pressure contact member suitable for the length, which facilitates the grip rotation operation and the pressure contact. The force also increases and the function as a lock can be fully exerted. In addition, the above advantages can be exhibited corresponding to each model. Furthermore, if an auxiliary pressure contact member having a surface material suitable for the pressure contact portion is prepared, the pressure contact portion will not be damaged. Therefore, since the number of locks can be reduced, the production cost and management cost can be reduced.
