Description

  The present invention relates to a glass door that opens and closes an opening of a housing or a passage.

2. Description of the Related Art Conventionally, a door that opens and closes an opening of a cabinet housing, a sliding door or a hanging door that opens and closes an opening of an indoor passage, and the like are formed of sheet glass.
For example, in the case of a small one such as a TV stand, the entire surface of the door is made of sheet glass and directly attached with a hinge or a magnet catch. However, when the door is large, the entire surface of the door is formed of sheet glass. It is difficult to do so, and in most cases, the glass plate is surrounded by a strong sash or a window hole is formed in the center of the plate material that forms the door, and the plate glass is fitted into the window hole. The current situation is (see, for example, Patent Documents 1 to 3).
Japanese Utility Model Publication No. 6-45059 JP 2001-90442 A JP 2003-278451 A

  However, according to the glass doors described in Patent Documents 1 to 3, since the four sides of the plate glass are surrounded by a wide sash, the portion of the plate glass is restricted, the visibility through the plate glass and the appearance of the entire door Is bad.

  In view of the above-described problems of the conventional technology, the present invention increases the vertical dimension of the plate glass that appears on the front surface without reducing the strength of the entire door, thereby improving visibility through the plate glass and the entire door. The purpose is to provide a glass door that can improve the appearance of the glass.

According to the present invention, the above problem is solved as follows.
(1) In the glass door that opens and closes the opening of the case or passage, the upper and lower and left and right edges of the front glass plate are covered with the upper frame material, the lower frame material, and the left and right vertical frame materials. The upper and lower parts of the material are joined to the upper frame material and the lower frame material, and the drag side frame in the shape of a thin hollow box having an inner end opened is fitted and fixed to the left and right vertical frame materials.

(2) In the above item (1), the drag side frame is constituted by a surface material that covers the front surface and the outer surface of the vertical frame material, and a back material that is detachably attached to the back surface of the surface material.

(3) In the above item (2), a sheet glass is formed by the inwardly protruding piece provided on the inner side surface of the vertical frame member and the front end of the forward piece formed by bending the inner end portion of the back surface forward. Grip the side edge of the front and rear.

(4) In any of the above items (1) to (3), the upper frame material, the lower frame material, and the left and right vertical frame materials are formed of an extruded material of an aluminum alloy, and the drag side frame is formed of a steel plate. To form.

(5) In any one of the above items (1) to (4), the upper front edge of the base portion in the upper frame member and the lower front edge of the base portion in the lower frame member are engaged with the upper and lower edges of the plate glass. A glass holding part is provided.

(6) In any one of the above items (1) to (5), the hinge device is attached to the drag side frame which is the base end side of the door.

(7) In any one of the above items (1) to (6), the handle is attached to the drag side frame on the free end side of the door so that the handle can be rotated at a required angle, and the latch device is operated to rotate the handle. In conjunction with this, it is attached to the opening of the housing or passage so that it can be engaged and disengaged.

(8) In any one of the above items (1) to (7), a locking device is provided on the drag side frame on the free end side of the door.

According to the first aspect of the present invention, the upper and lower and left and right edges of the plate glass are respectively covered with the upper frame member, the lower frame member, and the left and right vertical frame members, and the upper and lower portions of the vertical frame member are covered with the upper frame member. In addition, it is combined with the lower frame material, and further, the left and right vertical frame materials are formed in a thin hollow box shape with the inner end opened, and the drag side frame that bears the strength of the door is fitted and fixed, Without reducing the strength of the entire door, the area of the plate glass exposed on the front surface can be maximized, and the visibility through the plate glass and the appearance of the entire door can be improved.
In particular, since the drag side frames are provided on both sides, the bending strength of the entire door can be increased, and the glass sheet can be protected from collision with other objects when the door is opened and closed. By using the frame, it is possible to firmly attach a member that requires attachment strength, such as a hinge device, a handle, a latch, and a locking device.

As a result, the workability can be improved by removing the back surface material when attaching a hinge device, a handle, a latch, a locking device, or the like to them.

  According to the invention of claim 3, the inwardly protruding piece provided on the inner side surface of the vertical frame member and the front end of the forward piece formed by bending the inner end portion of the back surface forward, Since the side end is held from the front and back, the plate glass can be firmly supported by the vertical frame member and the drag side frame, and the appearance of the parting part of the plate glass can be improved.

  According to the invention of claim 4, the upper frame material, the lower frame material, and the left and right vertical frame materials are formed of an extruded material of aluminum alloy, and the drag side frame is formed of a steel plate. The Nyum alloy material can maintain rigidity and reduce weight to prevent cracking of the glass sheet, and the steel sheet supports the entire weight and provides strength to protect the glass sheet from collision with other objects. You can have it.

  According to the fifth aspect of the present invention, the glass holding portion that engages with the upper edge and the lower edge of the plate glass is provided on the upper front edge of the base portion of the upper frame material and the lower front edge of the base portion of the lower frame material, Since only this glass holding portion exists above and below, the vertical dimension of the plate glass appearing on the front surface of the door can be increased, and the visibility through the plate glass and the appearance of the entire door can be improved.

  According to the invention described in claim 6, since the hinge device is attached to the drag side frame which is the base end side of the door, the hinge device can be firmly attached to the glass door and is connected to the hinge device. The drag side frame on the base end side of the door can support the entire load of the glass door.

  According to the seventh aspect of the present invention, the handle and the latch device can be attached firmly and in good shape using the hollow portion of the drag side frame on the free end side of the door.

  According to the eighth aspect of the present invention, the locking device can be attached firmly and in good shape by utilizing the hollow portion of the drag side frame on the free end side of the door.
