Description

  The present invention relates to a sash including a sub-block.

  For the hinged door that is rotated around the vertical axis by the gripped door handle and opened and closed, a vertically long rod that is locked when moving in one direction and unlocked when moving in the opposite direction is interlocked with the rotation of the door handle. There are many cases in which a sub-block for preventing movement of the rod in the unlocking direction when the door handle is rotated in the unlocking direction illegally from the outside is provided. .

  Generally, the sub-block added to the Gremon lock device is moved to either the lock position or the unlock position by a fingertip pressing operation on the case and the case, and is held at the moved position by a spring or the like. If the hinged door to be built in the sash is a single-folded door, it is attached to the vertical wall of the hinged door. When the switch is locked, the stopper provided at the end of the switch approaches the locking part provided on the rod of the Gremon lock device, and the rod is moved in the unlocked position direction by operating the door handle. It is comprised so that it may prevent moving to.

By the way, in the conventional sub-block, the case where the hinged door is an all-metal sash made only of a metal profile, or the case where the hinged door is a composite sash composed of an outdoor-side metal profile and an indoor-side resin profile. The sub-lock needs to be installed at a position where the fingertip of the person who operates the sub-lock reaches the switch. At the same time, when the sub-lock is locked, the stopper portion of the switch is a Gremon lock device (hereinafter referred to as a lock device). It is necessary to install so as to engage with a locking portion provided on the rod. In order to satisfy these requirements, conventionally, in the case of an all-metal sash, it is directly attached to the interior side of the vertical or summoned sash, and in the case of a composite sash, the interior side resin profile of the vertical or summoned sash It was attached to. Accordingly, the sub-lock attached to the composite sash has to have a long switch length so that the stopper portion of the switch engages with the locking portion of the rod of the lock device.
nothing special

  Therefore, conventionally, it is necessary to prepare and place two types of sub-blocks for all-metal sashes and for composite sashes, resulting in high manufacturing costs and complicated product management. In the case of a composite sash sublock, the distance between the support shaft of the switch that performs the seesaw motion between the unlocking position and the locking position and the stopper is large, so the rod unlocks as the door handle is unlocked. When moving in the direction, the moment applied to the switch from the locking portion of the rod becomes very large. For this reason, the support shaft of the switch is broken, the switch is detached from the case, or worse, the sub-lock is fitted and fixed in the hole of the resin product on the indoor side. There is a risk that the sub-block will be forcibly released and the sub-block may be pulled out, or that the interior resin material may be damaged.

  The present invention has been made in view of the above points, and the problem to be solved is that one type of sub-block can be used in common for both an all-metal sash and a composite sash, and the switch An object of the present invention is to provide a sash that eliminates the need for extension, prevents an increase in moment load on the switch when the rod is moved, and does not cause damage to the sub-block or the indoor resin molding.

In order to solve the above-described problems, the present invention provides: (a) When the sash is a metal sash in which the hinge of the hinged door is composed of only a metal profile, (B) When the sash is a composite sash that is composed of an outdoor metal shape and an indoor resin shape, the sublock is located outside the door. Attached directly to the indoor side of the metal downpipe, the sub-block faces the indoor side from the hole provided in the indoor side plastic downpipe of the hinged door, and the inner peripheral surface of the hole of the indoor side plastic downpipe (C) The sub-blocks are all the same, and (c) the sub-block is attached to the indoor side.
With the above-described configuration, in the all-metal sash, the sub-block is directly attached to the interior side surface of the hinged metal shaft. In the composite sash, the sublock is directly attached to the interior side surface of the metal vertical wall of the hinged door, and a hole is formed in the indoor resin vertical wall of the hinged door corresponding to the sublock. A sub-block cover that is exposed to the inside and surrounds the periphery of the sub-block is attached to the indoor resin vertical shaft.

Further, in the composite sash, a seat plate is fixed to the outdoor metal cage, and a sub-lock is fitted into a hole provided in the outdoor metal cage and the seat plate, and a claw provided in the sub-block. It is desirable to lock and fix to the back side of the hole side of the seat plate (Claim 2).
With the above configuration, the seat plate is firmly fixed to the outdoor side metal rod, and it can be easily installed around the sub block just by fitting the sub block to the seat plate and the hole of the outdoor metal rod. The claw is locked and fixed to the back surface of the hole side of the seat plate, and the sub-lock is firmly fixed to the seat plate.

  It is desirable that the sub-block cover is fixed by locking a claw provided around the sub-block cover to the back side of the hole side of the indoor-side resin cage (Claim 3).

  According to the invention of claim 1, when the sash is an all-metal sash in which the hinge of the hinged door is composed only of a metal profile, the sash is formed of an outer metal profile of the hinged door. In any case where the composite sash is configured with the indoor resin shaped material, one type of sub-block can be attached to the outer metal shaped material in a common manner, that is, directly attached. The manufacturing cost of the sublock can be reduced, the mounting efficiency can be increased, and the mounting strength of the sublock to the hinged door can be increased regardless of whether it is an all-metal sash or a composite sash. In the case of a composite sash, the sublock is exposed to the indoor side from the hole formed in the indoor resin molding, and the periphery of the hole and the sublock is covered with the sublock cover. Is secured, the sub-block operator's hand is protected, and the appearance of the sub-block is improved.

  According to the second aspect of the present invention, the claw provided in the periphery of the sub-block can be easily locked to the back side of the hole side of the seat plate simply by fitting the sub-block into the hole of the seat plate and the outdoor metal rod. Therefore, the sub-block can be easily attached.

  According to the invention of claim 3, the claw provided in the periphery of the sub-block cover by fitting the sub-block cover into the hole provided at the position corresponding to the sub-block of the indoor-side resin cage is provided with the indoor resin. Since it is locked and fixed to the back side of the hole side of the iron making, the sub-block cover can be attached easily and more firmly.

It has a rod that fits in. The present invention can be similarly applied to such a case.

[Sublock configuration]
1-3, 40 is a sub-lock and is attached to the lower part of the indoor side surface of the summoning tub 24b of the right hinge door 20b. As shown in FIG. 4, the sub-block 40 includes a case 41 and a switch 43 that is fitted inside the case and is held by a support shaft 42 so that the seesaw can move freely. The case 41 integrally has a vertically long rectangular annular flange 41a on the front side and a cylindrical portion 41b extending from the back surface of the flange. The switch 43 is formed in a substantially rectangular parallelepiped shape, and is fitted to the cylindrical portion 41b of the case 41 by the support shaft 42 penetrating horizontally through the central portion of the switch in the longitudinal direction and the cylindrical portion 41b of the case 41. It is supported so as to be rotatable about a support shaft. However, due to the engagement between the upper and lower ends of the switch 43 and the upper and lower ends of the cylindrical portion 41b of the case 41, the pivotable angle is limited to a certain range.

  The front surface of the switch 43 is bent so that the upper half portion and the lower half portion are, for example, a rectangular shape with an angle of 150 degrees, with the position in the vicinity of the support shaft 42 as a boundary, and the lower half portion is an operation surface during locking. 43a, and the upper half part is an operation surface 43b when unlocked. A stopper 44 is provided at the lower end of the switch 43.

  The sub-lock 40 is shown in FIG. 4D from the locked position where the operation surface 43a when locked is flush with the front of the case 41 as the switch 43 is shown in FIG. 4B. When the unlocking operation surface 43B is rotated to the unlocking position that is flush with the front surface of the case 41, means for frictionally locking with the cylindrical portion 41b, for example, elastic locking pieces 45a and protrusions 45b are provided. Is provided. The elastic locking piece 45 a is provided on the case 41, and its tip engages with the switch 43, and the protrusion 45 b protrudes on the side surface of the switch and frictionally locks to the inner wall surface of the case 41. A tapered claw 46 is provided on the outer peripheral surface of the cylindrical portion 41b of the case 41 so as to protrude along the back surface in the vicinity of the flange 41a.

[Sublock mounting structure]
The sub-block 40 having the above-described configuration is attached to the sash as follows depending on whether the sash 1 is an all-metal sash or a composite sash.
[1. For all metal sashes]
When the sash 1 is an all-metal sash composed of only aluminum or other metal shapes as shown in FIGS. 2 and 3, as shown in FIGS. Then, it was fitted into a hole 24h provided in the lower part of the indoor side wall of the summoning bowl 24b and pushed so as to overcome the frictional resistance of the claw 46, and the back surface of the flange 41a hit the indoor side wall of the summoning bowl 24b and stopped. At times, each claw 46 is elastically restored and locked to the hole side of the indoor side wall of the summoning bowl, so that the sub-block 40 is fixed so as not to be removable.

  In that case, a metal locking piece 35 such as an O-ring, a U-ring or a pin is fixed to a predetermined position above the lower end of the rod 30 and moves up and down together with the rod 30 interlocked with the operation of the door handle 26b. . Then, the locking operation surface 43a of the switch 43 is pushed with the sub-block 40 attached at a predetermined position, the switch 43 rotates around the horizontal support shaft 42, and engages with the case 41b at a predetermined angle and stops. Then, as shown in FIG. 3, the stopper portion 44 moves to a position just above the locking piece 35 and prevents the locking piece 35 from being lifted, and the unlocking operation surface 43b is pushed and the switch 43 is moved. When it is rotated in the opposite direction and engaged with the case at a predetermined angle and stopped, the stopper portion 44 moves back to a position where the stopper piece 35 does not prevent the locking piece 35 from rising ((d) in FIG. 4 shows this state). Thus, the installation position of the locking piece 35 and the mounting position of the sub-block 40 are designed.

[2. For composite sashes]
Next, FIG. 5 shows a mounting structure of the sub-block 40 when the sash 1 is a composite sash in which each of the hinges 20a and 20b is composed of an outdoor metal shape and an indoor resin shape. This will be described with reference to the following drawings.
FIG. 5 is a cross-sectional view mainly showing a cross-sectional shape of the summing portion of the left and right hinged doors 20a and 20b of the composite sash, and the summoning tubs 24a and 24b are respectively provided on the indoor sides of the outdoor metal profiles 24am and 24bm. In order to improve heat insulation, the known indoor resin shaped members 24ap and 24bp having at least one hollow portion are joined by a known fitting slide method, and both shapes are fixed by screws 24s as necessary. It is an example.
In FIG. 5, the same shape is used for the left and right summit bowls 24 a and 24 b, the left hinge door 20 a is closed first, the right hinge door 20 b is then closed, and the Gremon lock device is locked. In order to lock the double door, the metal auxiliary rod 24 cm and the resin auxiliary rod 24 cp are coupled to the tip of the left summing rod 24 a by the fitting slide method to form the auxiliary summing rod 24 c. An example is shown.
However, according to the present invention, if the indoor side resin shape having a thickness in the indoor / outdoor direction is bonded to the indoor side surface of the outdoor side metal shape material, the shape of the sash assemblage of the composite sash There are no restrictions.
In any case, the indoor side wall of the outdoor metal profile 24bm and the indoor resin profile 24bp of the summoning bowl to which the door handle 26b for the locking device is attached are common as shown in FIG. In the position, rectangular holes 24mh and 24ph penetrating from the indoor side to the hollow portion of the outdoor metal shape member 24bm are formed.

  When attaching a sub-lock to a composite sash, as shown in FIG. 7, the same sub-block 40 as the above-described sub-block 40 is attached in the same manner as described above or preferably by using a seat plate 50. A sub-block cover 60 is used. The sub-block cover 60 surrounds the side peripheral surface of the sub-block 40, shields a gap generated around the sub-block 40 to be attached, and covers the edge of the hole 24 ph so that the outer appearance of the sub-block 40 is obtained. It also serves to improve and prevent injury to the operator's fingers. 7 is a perspective view of the back side of the sub-block cover.

  The sub-block cover 60 has a rectangular annular flange 61 and a cylindrical fitting portion 62 on the back surface of the flange, and at least upper and lower inner wall surfaces 64 forming a hole 63 inside the fitting portion are provided. The taper is formed in a tapered shape that is inclined toward the center side toward the back surface of the flange. This taper contributes to improving the visibility of the sub-lock switch and the fingertip operability. A tapered claw 65 is formed on the outer peripheral surface of the fitting portion 62 so as to protrude in the outer peripheral direction at a position close to the rear surface of the flange 61.

  In order to attach the sub-block 40 to the summoning tub 24b having the above structure, first, as a first step, as shown in FIG. 7 and FIG. The seat plate 50 is inserted into the hole 24ph of the profile member 24bp, and the seat plate 50 is brought into close contact with the indoor side surface around the hole 24mh of the outdoor metal profile member 24bm (FIG. 9A). Screws 50 s are screwed into the indoor side wall of the outdoor metal shape member 24 bm from the provided hole 51 and fixed. In this case, the hole side of the seat plate 50 slightly protrudes inward from the periphery of the hole 24mh of the outdoor metal shape member 24bm.

  Subsequently, as a second step, the sub-block 40 is inserted from the indoor side into the hole 24ph of the indoor-side resin shaped member 24bp, and further sub-blocked into the hole 53 of the seat plate 50 and the hole 24mh of the outdoor-side metal shaped member 24bm. The tube portion 41b of 40 is fitted first from the top (FIG. 9 (b)), the lower portion of the tube portion 41b is further fitted, and finally the flange 41a is kept in a vertical state while the flange of the sub-block 40 is placed. Until the back surface of the seat plate 50 comes into close contact with the hole side 52 of the seat plate 50, it is strongly pressed in the direction of the outdoor metal member 24bm. As a result, as in the case of the all-metal sash described above, the claw 46 provided on a part of the outer periphery of the cylinder portion 41b of the sub-block 40 is locked to the back surface of the hole side of the seat plate 50 and firmly fixed. To do. As a result, the sub-block 40 is directly fixed to the indoor side surface of the outdoor metal shape member 24bm, as in the case where the sub-lock 40 is attached to the all-metal sash summing bar 24b (FIG. 9C).

  Then, as a third step, as shown in FIG. 9C, the fitting portion 62 of the sub-block cover 60 is inserted from the hole 24ph of the indoor resin-made material 24bp, and the rear surface of the flange 61 of the sub-block cover 60 Is pushed into the indoor side surface of the hole side of the hole 24mh of the indoor resin shaped member 24bp, and the claw 65 projecting from the outer peripheral surface of the fitting portion 62 of the sub-block cover 60 is inserted into the indoor resin molding. The sub-block cover is fixed elastically to the back surface of the hole side of the material 24 bp.

  Thus, in the state where the sub-block 40 and the sub-block cover 60 are attached, as shown in FIGS. 6 and 9, the gap between the sub-block cover 60 and the hole side of the indoor side resin shaped member 24bp. Is closed by the flange 61 of the sub-block cover 60, the switch 43 of the sub-block 40 is exposed to the indoor side through the hole 63 of the sub-block cover 60, and the inner wall surface of the sub-block cover is from the inner peripheral portion to the outer peripheral portion. The switch is easy to operate because it is expanded in the indoor direction. Further, the sub-block cover simply fits into the hole of the indoor resin shape member 24bp, and the claw 65 formed on a part of the outer periphery is locked to the hole side of the indoor resin shape material 24bp. Since it is fixed, mounting is easy.

  By directly fixing the sub-block in the case of the composite sash to the indoor side surface of the outdoor metal shape member, it is not necessary to lengthen the switch, and the sub-block cover is provided on the indoor side surface of the indoor resin shape material. The structure with a taper on at least the top and bottom of the sub-block cover is characteristic of a composite sash that increases the mounting strength of the sub-block, reduces the moment applied to the switch, improves the operability of the sub-block and improves the appearance of the sub-block Can achieve the purpose.

  FIG. 10 is a diagram illustrating a problem in the case where the sub-block is directly attached to the indoor side surface of the indoor-side resin shaped member 24 bp in the composite sash. (A1) (A2) shows a structure in which the sub-block is directly attached to the outdoor metal shape material according to the present invention, and (B1) and (B2) are structures in which the sub-lock is directly attached to the indoor resin shape material 24 bp. Is shown. In (A1) and (A2), the sub-block cover is omitted for simplification of the drawing. When the sub-block is directly attached to the indoor resin shape member 24 bp, it is necessary to form the switch 43 long so that the stopper portion 44 of the switch 43 reaches the locking piece 35 of the rod 30. The disadvantages for this are as described at the beginning.
