Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a hardware attachment tool, and more specifically, to a support for adjustingably attaching a window sash to a window frame.

[Conventional technology]

protruding hanging window (proj@cted hung wi
(ndow) Sash is a window sash that is attached to a fixed window frame by at least a pair of supports. The window sash can be hung from the sides with supports located at the top and bottom of the sash, or from the top with supports located closer to the top edge of the sash. The sash is fixed to the window frame and the sash is connected to the window frame via an arm which is usually pivoted to the plate. A known embodiment of the window support includes a pair of arms of unequal length, each end of which is pivotally connected to the window frame and the sash mount to the plate. Such supports are often referred to as four-bar supports. It is also known to provide a six-bar support, which is essentially a four-bar support containing two additional arms. It is also known to provide these supports with one or more pivot points that can be slid during all or part of the opening and closing of the supports.

Irrespective of the structure or geometry, the protruding window supports provide a certain amount of "retraction", which is the final step in the closing of the sash. The retraction effectively constitutes a lateral movement or a component of lateral movement with respect to the plane of the window frame, so that the sash part on the side opposite to the internally fixed sash part moves inside the window frame. To ensure that the weather seal to the window frame or sash is normally compressed to provide an overall weather seal between the sash and the window frame, rather than the sash being moved to a fully closed position. Depending on the actual shape of the support, its retraction can take place by sliding one or more pivots or by fixed guides. A portion of the support engages the fixed guide to transmit the lateral movement or a portion of the lateral movement.

Standard specifications usually require that the projecting-hung window be able to resist opening when negative pressure is applied. This resistance to opening is provided in part by internal fixation of the sash (e.g. wedge lock), but primarily by ensuring that the part of the window sash opposite the part of the window sash to which the internal fastener is attached is opened by suction. This is due to the action of the blocking support.

Also, it is usually very difficult to obtain a support structure that provides sufficient retraction movement across the sash to compress the weather seal in its entirety.

The above requirements and difficulties associated with certain types of support structures are only possible if the support can fit into the limited (specifically narrow) space between the sash and the window frame. It is tied to today's demand that it should not be.

Although the invention is particularly suited to hardware fittings in the form of window supports, other fittings having at least one moving part and the fitting may also be used with fittings. Therefore, although the following description relates to window supports, the invention is not limited thereto, but can also be applied to other hardware such as window/door closers, window fasteners, etc.

[Problem to be solved by the invention]

It is an object of the present invention to provide a hardware attachment comprising means for retaining a movable part so that the movable part does not move relative to the fixture when the movable part is in at least one position relative to the fixture. It's about getting the ingredients.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the detailed description that follows, the structure of the support shown in Figures 1 to 4 will be explained in more detail below. It has a four-bar structure with a pair of arms. An opening (not shown) is provided in the board for installing the sash and the board for installing the window frame. These openings allow the sash attachment plate and window frame attachment plate to be attached to the window frame and window sash. The arm is connected to the plate by means of a pivot joint. Preferably, the pivot joints use friction pivot joints of the type disclosed in any one of the following two knee sealant patent specifications: That is, No. 144922, No. 1621
No. 919, No. 196479, No. 195036, No. 2
No. 02214, No. 212599, No. 223073.

The support shown in FIGS. 5 and 6 is a parallel acting support of the type disclosed in commonly owned New Sealant Patent Specification No. 219,875.

The support shown in Figures 1 to 4 has a plate 10 for attaching the window frame and a plate 11 for attaching the sash. In their attachment, the plates are connected together by short arms 12 and long arms 13. A pivot joint is designated by reference numeral 14. For their mounting, the plates and arms are manufactured in a conventional manner (so that the ends of arms 12 and 13 are formed like cranks 15.The arms are connected to the plate 10 for window frame mounting. The thickness and construction of the mounting board 10 is such that a groove, recess or cavity extends in the longitudinal direction of the mounting board.

In the following discussion, the illustrated supports will be described as if they were in a vertical orientation, such as when attached to sashes and window frames in projecting side hanging applications.

The window frame attachment is arranged inside the plate 10 so that the plate 16 can slide in the longitudinal direction. The lower end of the sliding plate 16 is connected to a slotted plate or bottom plate 17 located above the surface of the plate 10 and just below the lower pivot joint of the arm 13. . Slide plate 16
A sliding band 18 is connected to the upper end of the . The window frame attachment of the sliding pad 16 protrudes from the plate 10 and is bent rearward. It will be seen that near the top band 18 the window frame attachment has had a portion of the surface of the plate 100 removed. Arm 1
2 is provided with a bin 19, the sash attachment is provided with a protrusion or slider 20 near the lower end of the plate 11, and the attachment is provided at an angle across the width of the plate.

To complete the description of the structure of the support, reference will be made to the support during the final closing operation.

As shown in FIG. 1, during the final stage of closure the bottle 19 comes into contact with the sloped surface 21 of the top pad 18. The mutual contact of the bin 19 and the ramp 21 causes the sliding plate 16 to be moved upwardly so that the slot 22 of the bottom plate 17 is correctly positioned so that the protrusion 20 can enter therein. For example, wear 6
If slide plate 16 were to "fall" when the support was in a top-hung condition due to rounding or reduced friction, then bin 1
9 repositions the sliding plate 16t to the correct operating position by means of the inclined surface 21. At the front of the slot 22 and at the front of the protrusion 20, ramps 23, 24 are provided, respectively.

As the brace continues to close, the bi/19 continues to move across the top pad 18 and the protrusion 20 enters the slot 22.

The shape and position of the slot 22 and the protrusion 20 are such that the protrusion contacts the lower slope of the slot 22 and applies a downward sliding motion to the sliding plate 16, and the bottle 19 contacts the slope 25 of the upper pad 18. It's like sliding along the surface. The downward movement of the sloped surface 25 and the slide plate 16 adds a lateral component of movement that forces the sash into the window frame. However, in addition to that, the bin 19 will be fixed to the plate due to the presence of the inclined surface 2.

When the window sash is secured closed by an internal latch at or near the bottom of the sash, the projection 2
0 and the slot 22 prevent upward movement of the slide plate 16 so that the bottle 19 remains on the ramp 25 until such time as the window is unlocked and the sash is pushed open.
was caught and seen. During the operation of opening the sash, the operation opposite to the above is performed, and the sliding plate 16 is raised by the protrusion 20 sliding into contact with the upper inclined surface of the slot 22. Pin 19 is then released and moved away from upper band 18.

A sloped portion 26 is provided at the top of the sliding plate 16.

The slope part toggles too much during the closing operation (ov@r1
It functions as a kickout (Klek-out) to prevent 6ggling)'. However, such a structure is not required in the alternative embodiment shown in FIG. 4, in which an upper slider 27, which engages in a slot 28 of the slider pad 1B, is used in place of the pin 19. .

Therefore, the support of the present invention provides a structure in which the sash can be reliably and forcibly retracted at the end of the support having a short arm, and the window frame can be attached at the lower end of the board as well. be.

This overall retraction or forcing action is achieved by the predetermined angle and predetermined relationship of the pivot 14 and the short arm 1.
2, the position of the bin 19 and the radiumed action of the window flange. However, this action is always no more than the actual seal compression (at least 5-10 mn of forced movement).

Also, the short arms of the support are fixed when in the locked position, thereby holding the parts of the sash that tend to be sucked out when negative pressure is applied to the sash.

In the support structure described and illustrated above, the final movement of the support when closed is approximately perpendicular to the plane of the window frame. Therefore, it eliminates seal friction or seal slippage, resulting in a longer seal life and better sealing.

FIG. 1 also shows a pair of additional links 50.51 that can be incorporated into this support. One end of the link 50 is pivotally connected to the long arm 13, and one end of the link 51 is attached to the window frame mounting plate 1.
Pivoted to 0. As shown, the pivot points of links 50 and 51 are spaced from adjacent pivots 14 that pivot arms 13 and 12 to mounting plates 11 and 10, respectively. The other ends of the links 50 and 51 or near the other ends are pivotally connected by a pivot 52 . Pivots 52 and 53 can be frictional or non-frictional.

Those additional links that act like scissors 50.51
They help support the inside hanging applications of the sash and add more friction through their additional bearings. The added friction is caused by the fact that the support is a top hung structure.
<Kl is required when used in configuration).

Due to the provision of one additional linkage in the conventional four-bar support structure, this support can also support larger loads. However, the ends of links 50 and 51, which are preferably connected together in an overlapping manner by pivot 52, extend beyond pivot 52t. Their superposition of the connections of the links provides better support. A friction pad or plastic washer 54 is placed over the extended portion 55 of one link on the opposing surface of the other link throughout the angular movement of one link relative to the other link, or until the extension 55 is partially The electric fit can also be used to increase friction to achieve a targeted or complete fit.

Reference is now made to FIGS. 5 and 6 in which the window supports are shown.

Figures 5 and 6 show the window support in the fully open position. In the fully closed position, the mountings are placed on the plates, the arm and the link arm are sandwiched between the mounting plates, and the mounting plate is placed approximately on top of the plate on the other mounting. You will see that it will happen.

The support has a plate 31 in the first mounting and a plate 32 in the second mounting. Although each mounting plate can be a single member or a two-part member, the single member construction shown is preferred for ease of mounting and accurate centering. In mounting, plates 31 and 32 are connected together by a pair of arms 34. Each arm 34 is connected to the plate 31.32 by a pivot joint 35 provided at the end of the arm 34 and preferably at the end of the plate. As can be seen, the pivot point 35 and therefore its pivot point are offset from the longitudinal centerline of the plate. The deviation is toward the outer edge of the plate.

The arms 34 themselves are connected together in the longitudinal direction by a pivot portion 3T. Its pivot 37 is also offset with respect to the longitudinal centerline of arm 34, and the mounting with pivot 35 is located closer to the ends of plates 31 and 32.

The other end of the arm 34 is pivoted to a link arm 39. The link arm 39 is attached to the plate 31 by the pivot joint 40.
and 32. Pivot joints 40 and 41 (link arm 39 connecting arm 34) are shown with their attachments offset toward the respective center lines of the plate and link arm.

Each mounting plate 31 and 32 has a pair of uprights 42 . Their uprights form stops that limit the range of movement of the link arm 3S. The stops 42 define a fully open position and a fully closed position. The link arm 39 is shown in contact with the stop 42 in the fully open position of the support. In the closed position, the other stop 42 enters the recess 42& in the arm 39.

The pivot parts 35, 37, 40, 41 can be simple pivots, and the friction bearing i9 can be a combination of both.

When this support is used, the plates 31 and 32 are attached to the window sash and the opposite edges of the window frame in a conventional manner.

Their attachment is such that plates 31 and 32 can be attached by means of suitable mechanical fixing devices.
An opening 33 is provided therein. Therefore, the sash is supported by the pair of supports at a position that is placed within the window frame so as to be substantially parallel to the window frame. Thus, when the support is moved into and out of the closed position within the window frame, the sash acts to effect movement parallel to the opening formed in the window frame. link arm 39
controls the movement and allows the depth of the scissor-like assembly to be varied without the sash moving perpendicular to the window frame. Link arm 38 in closed position of stop 42
Prevents the [toggleover (toggl@oma・r)J and maintains the retraction of the satsushi. The stop 42 also serves to limit the extent to which the brace can be "opened" as shown.

Unlike conventionally installed protruding hung windows, the lateral edges of the sash remain in place in all opening positions of the sash, and during the opening and closing movements of the sash. You will find that none of the others are close enough to the window frame. This action of the support differs from conventional scissor-type supports because it can be performed without the need for sliding elements.

Similar to the embodiment previously described, the sliding plate 16 is arranged with one mounting plate. One end of the slide plate 16 supports the fixation element. The fastening element has a protruding tongue 43. The other end of the sliding plate 16 supports a pad 44ft having an inclined surface 45f.

For other installations, the plate is supported by a metal fitting 46f at one end.

For this installation, the metal fittings have a recess 4T. Another attachment is that the other end of the plate supports a protrusion 48 having an inclined surface 49. The sliding plate 16 can be mounted by sliding in the direction indicated by the arrow near the end of the plate.

The installation occurs as a result of the relative movement of the plates; as the plates approach each other, the tongue 43 enters the recess 4T, with the result that the sliding plate 16 moves downwards (as viewed in FIG. 5). . Therefore, the sloped surface 49 of the protrusion 48 is connected to the pad 44.
The sash is forced into the window frame as in the previously described embodiment. Nineteenth, the locking action described above takes place.

When the window is opened, the opposite operation is performed.

During this action, the top of the window is pushed out of the opening in the window frame and
Open the seal in a controlled manner. There is usually a tendency for the window to be pushed back against the seal. Mechanical benefits are provided by the movement of the slider and by pushing out the window and opening the seal.

Traditionally, seals are attached to the sash or window frame.

A further embodiment of the invention is shown in FIGS. 7 and 8.

In this embodiment, the sliding plate 16 is slidably disposed within the nozzle 56. The housing 56 can be formed with the window frame attachment plate 10, or the window frame attachment can be formed separately from the plate 10. If the window frame attachment is formed separately from the plate 10, the nozzle 56 may be used with standard window supports used in severe negative pressure situations. It can be done. No-Uji Pufferfish 56 can be made of any suitable plastic material.

As shown in the figure, the mounting 56 is provided at one end (upper end) of the window frame mounting plate 10. It is preferable to arrange the plate ssa t on the lower side and extend the plate by the length of the plate 10 when attaching the window frame. The plate 56& is arranged on the underside of the groove portion 5T of the nozzle 56, so that the sliding plate 16 is inserted therein.
is inserted to form a slippery passage. A passage can be formed in the plate 561 that is fitted into the passage portion 5T.

One end 5T of the housing 56 forms a curved inclined portion 58. This elongated housing 56 has a raised surface 59
Also included. This surface engages the arm 130 surface during the final closure of the brace (and during the initial opening of the brace) to
Friction is increased in the manner of a friction pad 54 and an extended portion 55 as shown. Also, the raised surface 59 can form a stop that engages the arm 12 to limit the extent of release of the support.

The sliding plate 16 has a structure similar to that shown in FIG.
A protrusion 60 including an inclined surface 22& is supported at the lower end thereof.

A tongue 61 extends from the protrusion 60. The tongs 61
engages with or accommodates one end of the spring 62.

The other end of the spring 62 is fixed to a fixed plate 56a.

To further explain the structure shown in FIGS. 7 and 8, the operation of the supports will now be described. During the final closing movement of the support, the protrusion 201 supported by the arm 12 comes into engagement with the ramp formed by the ramp 22&. At the same time, the protrusion 19 of the arm 12 &
moves across the curved surface 58. Projection 20
The mutual engagement of the mounting plate 10 and the inclined surface 22M causes the protrusion 60 to be moved downwardly relative to the mounting plate 10, thereby causing the sliding plate 16 to
A longitudinal movement of is caused.

When the projection 20m reaches its final position (indicated by dashed lines in FIG. 7), the ramp 22& is moved to the position shown by dashed lines and the upper pad 18 is shown by dashed lines. moved into position. A pin 19M is placed in that position and held at the end of the curved surface 58. Preferably, a recess 63 is provided for receiving the pin 19a'. Similarly, a recess 64 for receiving pin 20a
A window frame attachment can be provided on the plate 10.

The surface 25 of the upper band 1B not only engages and holds the pin 1Sa in position to fix the support in the closed position, but also provides a constant lateral By transmitting a directional movement to the pin 191, the desired retraction is achieved in the final stage of closure of the brace.

Similar to the embodiment described above, when the internal mirror is unlocked and opened for the first time, the via 20a f: (presses the sash so as to push it out of the recess 64. Because it is biased by the spring 62, , the protrusion 60 is pushed up and the sliding plate 16 is slid, thereby releasing the pin 19m and allowing the short supporting arm 12 to move freely to facilitate opening of the window sash.

One advantage of this embodiment of the invention is that the position of the pins 2G and ramps 22 provides greater leverage, so that greater force is available for actuating the locking device. Furthermore, since the sliding plate 9 is attached to the window frame by extending only a portion of the length of the plate 10, the fixing device becomes even more compact. This will also provide an economical structure. Finally, as previously explained, this device can be provided as an "adoo/" for use with existing window supports.
