Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fitting for a floor automatic adhesion device provided in a lower frame of a soundproof airtight door used in halls, studios and the like.

[0002]

[Prior art]

 Although various structures are used for the floor surface automatic contact device of the soundproof door, basically, the lowering member (plunger) housed in the housing with the inverted U-shaped recess is closed when the door is closed. It has a structure that is closely attached to the surface. The conventional mounting structure is as shown in FIGS. 1 and 2, 1 is a door, 2 is a lower frame, 3 is a side frame on the hinge side, 4 is a fixed pillar, 5 is a side on the door tip side. A frame, 6 is a fixed column, and 7 and 8 are exterior plates or decorative plates on the front surface or the back surface of the door. Reference numeral 9 denotes a complementary frame, in which a step portion 10 for accommodating the housing 21 of the floor surface automatic contact device 20 is formed on the door contact surface side, and the housing 21 is fixed by a fixing screw 13 penetrating the housing , And the surface is covered with a decorative plate 7. 22 is a descending member (plunger). The housing 21 of the contact device is fixed to the complementary frame 9 of the lower door frame 2 with screws 13 before mounting the exterior plate 7 of the lower door frame, and after this fixing, the screw holes are filled, The exterior plate is attached and the paint or the decorative plate is attached. Therefore, when removing the contact device from the completed door, it is necessary to remove the entire door from the fixed pillar on the hinge side and then perform the reverse operation. That is, in the above conventional door, the entire door must be removed from the hinge side every time when the device malfunctions at the installation site for inspection, repair or replacement, but in the first place, the soundproof door has a large weight in order to improve the soundproof performance. Since it is manufactured (200 kg to 300 kg), it requires a large number of workers and a large-scale transportation means, which makes the work extremely inefficient and uneconomical. Also, even if the door is removed, it is possible to remove the device only by peeling off the exterior plate or looking for screw holes coated with paint for flattening.

[0003]

[Problems to be solved]

 This proposal provides a mounting bracket that can be attached / detached to / from the floor automatic adhesion device that is attached to the lower frame of the door with simple work both during door manufacturing and during repair work. It is made of aluminum material and has a comparatively light weight. Moreover, it can be detachably fixed on the door end side and the hinge side of the door by utilizing the shape characteristic that the same end surface appears wherever the cutting surface. Is.

[0004]

[Means for solving]

 The mounting bracket of the present invention is composed of a board that is fixed to the side end surface of the door lower frame by closing each end surface on the hinge side and the door end side of the housing, and a groove formed inside the housing protruding from the inner surface of the board. The hinge-side closed board is formed with an insertion / removal insertion hole, and the groove for inserting the support protrusion is the uppermost stage in the housing. It is preferably an empty space.

【Example】

 3 and 4, 24 is a pin fixed to the upper part of the plunger 22, 25 is a spring plate for hanging, 26 is a fixed plug, and 27 is a slide plug, which is fitted in the guide groove 28 in the housing. Have been combined. Reference numeral 29 denotes an advancing / retreating rod with a screw, to which a retractor 30 also serving as a protruding length adjusting screw is screwed. Reference numeral 31 is a recessed groove for forming a locking step of the retractor formed at the uppermost part of the housing, and forms a space inside the housing together with the plunger housing 32. The housing 21 of the apparatus is inserted from the bottom surface 12 side into the insertion groove 11 formed by the complementary frame 9 and the exterior plate 7, or from the hinge side or the door tip side. As shown in FIG. 5, the mounting bracket 40 of the present invention has an L-shaped or rod-shaped support projection 43 fixed to the inner surface 42 of a metal substrate 41 such as stainless steel fixed to the end surfaces 15 and 16 of the door side frame by welding or the like. The end surface of the housing is closed. Reference numeral 44 is a screw hole for fixing, and 45 is an insertion hole for the retractor, which is provided only on the hinge side metal fitting. 46 is a fixing screw. The supporting protrusions 43 of the mounting member 40 fixed to the side frame end surfaces 15 and 16 are inserted into the groove groove 31 of the housing to support both ends of the housing 21, and thus support the entire apparatus. Further, since the base plate 41 of the mounting fitting closes the end surface of the housing, the housing 21 and the plunger 22 are prevented from swinging in the longitudinal direction and are held in a fixed position. When it is necessary to remove the housing, the fitting device on either the door tip side or the hinge side can be removed to easily pull out the entire contact device to the outside of the door.

[0006]

【effect】

 According to the mounting bracket of the present invention, the positioning and fixing work of the device at the time of manufacturing the door can be omitted, and in the case of replacement and repair, the large-scale work and cost as in the past can be significantly reduced.
