Description

  The present invention relates to an opening device in which a windshield plate is provided on an upper frame of a frame corresponding to a shoji summon bowl in a sliding window provided in a building.

In general, a sliding window in which a sliding-type shoji is arranged in a four-sided frame is known. In this type, a windshield plate is attached to the upper frame of the frame corresponding to this shoji summon bowl, and this windshield plate allows the upper edge of the summon bowl to correspond to the upper frame. Airflow between them is prevented. This windbreak plate is formed to have a length approximately equal to or longer than the width dimension of the summon bowl, but when it is attached to the upper frame of the frame body, it is generally fixed by, for example, screws. It is. However, fixing with screws requires processing of the upper frame and takes time to remove and fix the windshield plate. In order to solve this problem, for example, as a sliding stopper for the shoji, etc., a mechanism in which the locking stopper is fixed to the holding groove of the upper frame with a rotation stopper claw has been proposed (see Patent Document 1).
JP 2000-352257 A

  However, since the windbreak plate is formed to be approximately the same length as or longer than the width of the summoning bowl, it becomes relatively large and heavy in weight as compared with a general stopper. If, for example, it is attached to the upper frame in a standing posture while holding the windshield plate, there is a problem that workability is poor.

  Then, the objective of this invention is providing the opening part apparatus which can attach a windshield board easily to the upper frame of a frame.

  The present invention is provided with a sliding frame type shoji on a four-sided frame, a windshield plate on the upper frame of the frame corresponding to the summon of the shoji, and this windshield plate holds the upper frame. A temporary stop claw that is slidably engaged with the groove, and a rotation stop claw that fixes the wind stop plate to the holding groove of the upper frame are provided.

  In this invention, when the windshield plate is fastened to the upper frame of the frame body, first, the temporary fastening claw formed on the windshield plate is engaged with the holding groove, and in this state, the windshield plate is placed at an arbitrary position. That is, it slides to the position of the upper frame of the frame corresponding to the summon of the shoji, and then the windshield plate is fixed to the holding groove of the upper frame by using the rotation stop claw of the windshield plate. In this configuration, since the windshield plate is temporarily fixed to the holding groove of the upper frame by the temporary fixing claws, for example, it is possible to slide it by hand without holding the windshield plate, and at a desired position. After being slid into the upper frame, it is fixed to the holding groove of the upper frame using a rotation stop claw, so it is not necessary to attach it to the upper frame with the windshield plate in a standing posture as before, Improves.

  In this case, a pair of provisional pawls may be provided on both sides of the rotation pawl. If it is formed with a gap between the pair of temporary fixing claws, even if the length of the windshield plate is increased, this windshield plate can be firmly temporarily fixed in the holding groove of the upper frame. The work of sliding the plate can be easily performed.

Further, at least one temporary fixing claw may be provided with a pair of snap-type knob portions, and the temporary fixing claws may be formed so as to be freely removable from the holding groove by operating the knob portions.
In this invention, when the windshield plate is removed from the holding groove of the upper frame, first, the engagement between the windshield plate and the upper frame is released by the operation of the rotation stopper claw, and then the knob portion of one temporary stopper claw is removed. By operating it, the temporary pawl is made to escape from the holding groove.
At this stage, even if the other temporary fixing claw is held in the holding groove, if the one temporary holding claw is grasped and pulled downward, the other temporary fixing claw can be easily escaped from the holding groove by this pulling force. be able to.

  In the present invention, since the windshield plate is temporarily fixed to the holding groove of the upper frame by the temporary fixing claws, for example, it is possible to slide the hands without releasing the windshield plate. And after sliding it to the desired position, it is fixed to the holding groove of the upper frame using the rotation stop claw, so that the windshield plate is held on the upper frame in the upright position as before. There is no need to attach it and workability can be improved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The sash window 10 is configured by combining a window frame (frame body) 1 and a shoji 6 in which glass fitted in the window frame 1 is steadily fitted. The window frame 1 is formed by joining an upper frame 11, a lower frame 12, and vertical frames 13 at both left and right ends in a square frame shape. The upper frame 11, the lower frame 12, and the vertical frame 13 are each made of a profile made of aluminum which is a non-ferrous metal. Further, the outer and inner rails 16 and 17 are integrally suspended on the lower surface of the upper frame 11, and the outer and inner rails 18 and 19 are integrally erected on the upper surface of the lower frame 12. Yes.

  The shoji 6 arranged in the window frame 1 includes an outer shoji 6A arranged on the outdoor side and guided by the outer rails 16 and 18, and an inner shoji 6B arranged on the indoor side and guided by the inner rails 17 and 19. And. Each of these shojis 6A and 6B has an upper cage 61, 62, a lower cage 63, 64, left and right cages 65, 66, an outer summing rod 67, and an inner summoning rod 68 in a square frame shape. It is composed. A multi-layer glass 29 is fitted to the inner peripheral surfaces of the flanges 61 to 68 via gaskets 30. Sliding pieces 31 that sandwich the rails 16 and 17 are fitted into the upper rods 61 and 62, respectively, and a door wheel 32 that rolls on the rails 18 and 19 is rotatably supported by the lower rods 63 and 64. Has been.

  In the present embodiment, a windshield plate (a member indicated by hatching in FIG. 2) 100 is attached to the lower surface of the upper frame 11 of the window frame 1 corresponding to the summing rods 67 and 68 of the shoji 6. The windshield plate 100 is made of resin, and includes a windshield portion 101 having substantially the same width as the width dimension W of the sump rods 67 and 68, as shown in FIG. A plurality of fins 102 extending toward the upper collars 61 and 62 of the shojis 6A and 6B are integrally formed at intervals in the sliding direction of the shojis 6A and 6B.

  As shown in FIGS. 4 and 5, the windshield plate 100 has a pair of snap-shaped knob portions 103 on one side of the windshield portion 101, and the knob portions 103 are indicated by arrows P in FIG. 4. The first temporary fastening claws 105 are formed integrally with the free ends of the knobs 103 so as to project laterally. On the other side of the windshield portion 101, a rotation stop claw 107 for fixing the windshield plate 100 to the upper frame 11 is formed, and a height adjustment member is provided on the rotation stop claw 107 via a thin portion 110. 111 are connected.

  As shown in FIG. 4, the rotation-stop claw 107 includes a main body 107A and a lock member 113 that is attached to the opening 107B of the main body 107A so as to be rotatable relative to each other. The lock member 113 is formed integrally with the substantially cylindrical main body 113A, a pair of locking claws 113B that are freely bent in the direction of the arrow Q, and an outer periphery of the main body 113A. And a pair of lock claws 113C that can be bent in the direction of the arrow R, and each lock claw 113C is integrally formed with a protrusion 113E. When the locking member 113 is attached to the opening 107B of the main body 107A from the side of the locking claw 113B, the locking claw 113B repels in the direction of the arrow Q to form a step portion 107C formed on the periphery of the opening 107B. The locking claw 113B is positioned so as to protrude over the sliding surface 107D of the stepped portion 107C. In this state, the locking claw 113C is connected to the main body of the rotation stopping claw 107 as shown in FIG. Projects to the outside of 107A. Further, second temporary fixing claws 109 are integrally formed on both side edges of the main body 107A of the rotation stopping claw 107, respectively.

Next, a procedure for attaching the windshield plate 100 will be described.
6A is a perspective view showing a state in which the windshield plate 100 is temporarily fixed to the upper frame 11, FIG. 6B is a plan view of the same, FIG. 6C is a cross-sectional view of the upper frame 11, and FIG. FIG. 7B is a plan view and FIG. 7C is a cross-sectional view of the upper frame 11. Each figure is shown upside down for convenience of explanation, and the fin 102 faces downward when the windshield plate 100 is attached.

In this embodiment, when the windshield plate 100 is fastened to the upper frame 11 of the window frame 1, first, as shown in FIG. 6B, a tool such as a Phillips screwdriver is inserted into the cross groove 113D at the top of the lock member 113. The pair of locking claws 113C is prevented from entering the holding groove 121 (see FIG. 6A) of the upper frame 11 by rotating the contact and rotating the first temporary fastening claws 105 at the free end of the knob portion 103. Then, the second temporary fixing claws 109 formed on both side edges of the main body 107A of the rotation stopping claw 107 are locked in the holding grooves 121 of the upper frame 11 to be temporarily fixed.
In this state, the windshield plate 100 is held by the first temporary fixing claw 105 and the second temporary fixing claw 109 and is slidable along the holding groove 121 of the upper frame 11. Even if the operator releases his hand, the windshield plate 100 does not fall.

  Next, the windshield plate 100 is slid to an arbitrary position, that is, the position of the upper frame 11 of the window frame 1 corresponding to the summing rods 67 and 68 of the shoji 6A and 6B. Then, as shown in FIG. 7B, a tool such as a Phillips screwdriver is applied to the cross groove 113D at the top of the lock member 113, and the tool is rotated by approximately 90 °. Then, the pair of lock claws 113 </ b> C enters the holding groove 121 of the upper frame 11. When this state is reached, the protrusions 113E of the pair of locking claws 113C strongly hit the groove wall of the holding groove 121 of the upper frame 11, whereby the windshield plate 100 is firmly fixed in the holding groove 121 of the upper frame 11. Will be stopped.

  In order to remove the windshield plate 100, the lock member 113 is first rotated to cause the pair of lock claws 113 </ b> C to escape from the holding groove 121 of the upper frame 11, contrary to the above-described procedure. Then, the knob part 103 is pinched with both hands, and the 1st temporary fix | stop nail | claw 105 is made to escape from the holding groove 121 of the upper frame 11. FIG. In this state, only the second temporary fixing claw 109 is locked in the holding groove 121 of the upper frame 11. Next, when the grip portion 103 side is grasped and pulled downward, the pulling force causes the second temporary fixing claw 109 to escape from the holding groove 121, and the windshield plate 100 is detached from the holding groove 121 of the upper frame 11. It is.

  In the present embodiment, since the windshield plate 100 is temporarily fixed in the holding groove 121 of the upper frame 11 by the temporary fixing claws 105 and 109, for example, even if the windscreen plate 100 is released, the holding groove Omission from 121 is prevented. As a result, the workability of sliding the windshield plate 100 to the desired position is improved, and after the slide to the desired position, the windshield 100 is simply rotated by rotating the lock member 113 of the anti-rotation claw 107. The plate 100 can be easily fixed to the holding groove 121 of the upper frame 11. Therefore, it is no longer necessary to attach the windshield plate 100 to the upper frame 11 while holding the windshield plate 100 in a standing posture as in the prior art, and the workability of the attachment is greatly improved.

  Further, since the pair of temporary fixing claws 105 and 109 are provided on both sides of the rotation stopping claw 107, the distance between the pair of temporary fixing claws 105 and 109 is large, and the length of the windshield plate 100 is increased as in this configuration. Even when the length of the windshield plate is long, the windshield plate 100 can be securely fastened to the holding groove 121 of the upper frame, and the work of sliding the windshield plate 100 is also compared to the conventional one. It can be done easily.

  At least one temporary fixing claw 105 includes a pair of snap-type knob portions 103, and by operating the knob portion 103, the temporary fixing claw 105 can be easily escaped from the holding groove 121. When removing the plate 100, first, the engagement between the windshield plate 100 and the upper frame 11 is released by the operation of the rotation stop claw 107, and then one temporary fastening claw 105 is made to escape from the holding groove 121, and this temporary fastening. If the side of the claw 105 is grasped and pulled downward, this temporary pulling claw 109 can be easily escaped from the holding groove 121 by this pulling force. Therefore, the removal workability is improved.

In this configuration, as shown in FIG. 3, a height adjusting member 111 is connected to the rotation-preventing claw 107 via a thin portion 110. A screw member 123 is screwed into the height adjusting member 111, and the tip of the screw member 123 is in contact with a receiving member 125 that integrally extends from the main body 107 </ b> A of the rotation stopper claw 107. The height adjusting member 111 can adjust the gap δ between the upper ends of the shojis 6A and 6B and the lower end of the height adjusting member 111. When the gap δ is larger than the margin for the lower frame rail, when the shoji 6A and 6B are lifted when the shoji is opened and closed, the shoji is detached from the lower rail and falls off.
When adjusting the gap δ, the screw member 123 is tightened. As this is tightened, the state gradually shifts from FIG. 3B to the state of FIG. 3C, and in FIG. 3C, the gap δ becomes zero. In this configuration, the windshield plate 100 has a function of preventing the clearance δ from being removed in addition to the function of preventing ventilation, and the clearance δ can be adjusted very easily.

  In this configuration, since the anti-slip adjustment function is provided in addition to the ventilation prevention function, the length of the windshield plate 100 is longer than that of the conventional one. In this case, the weight is generally increased and handling and workability are deteriorated. However, in the present embodiment, the windshield plate 100 can be attached and detached very easily by the above configuration.

Further, as shown in FIG. 8B, a finger hook portion 203 that is recessed in a concave shape is formed on one side portion of the windshield portion 201.
On the other side of the windshield portion 201, a rotation stop claw 207 for fixing the windshield plate 200 to the upper frame 11 is formed, and the height of the rotation stop claw 207 is adjusted via a thin portion 210. The member 211 is connected. The configurations of the rotation stop claw 207 and the height adjusting member 211 are substantially the same as the configurations shown in FIGS. 4 and 3, respectively, and the same portions are denoted by the same reference numerals and description thereof is omitted.

  In this embodiment, as shown in FIG. 8B, a pair of first temporary fastening claws 205 is formed at the end of the windshield portion 201, and a pair of second temporary fastening claws 209 is formed on the main body 207A of the rotation stopping claw 207. Has been. When the windshield plate 200 is fixed to the upper frame 11 of the window frame 1, the first temporary fixing claw 205 and the second temporary fixing claw 209 are locked in the holding groove 121 of the upper frame 11, Set to the temporarily fixed state. In this state, the windshield plate 200 is temporarily fixed and is slidable along the holding groove 121 of the upper frame 11. At this time, the windshield plate 200 falls even if the operator releases his / her hand. There is nothing. Next, the windshield plate 200 is slid to an arbitrary position, that is, the position of the upper frame 11 of the window frame 1 corresponding to the summing rods 67 and 68 of the shoji 6A and 6B, and the lock member 113 of the rotation pawl 207 is moved to about 90. Rotate. Then, as in the above embodiment, the pair of lock claws 113C enters the holding groove 121 of the upper frame 11, and the protrusions 113E of the pair of lock claws 113C strongly against the groove wall of the holding groove 121 of the upper frame 11. The windshield plate 200 is firmly fixed in the holding groove 121 of the upper frame 11.

  In order to remove the windshield plate 200, the lock member 113 is first rotated to cause the pair of lock claws 113 </ b> C to escape from the holding groove 121 of the upper frame 11, contrary to the above-described procedure. Then, when the finger is placed on the recessed finger hook 203 provided in the windshield 201 and pulled down, the temporary catching claws 205 and 209 escape from the holding groove 121 by the pulling force. Then, the windshield plate 200 is removed from the holding groove 121 of the upper frame 11.

  In the present embodiment, since there is no so-called snap-type knob 103 (see FIG. 5), the work of removing the windshield plate 200 is somewhat troublesome, but the windshield plate 200 is reduced in size and weight accordingly. Effects such as
