Description

[Detailed description of the invention] The present invention relates to a friction stay for windows.

The deflecting friction stay is constructed and arranged to augment the sash on the fixed frame for adjustable movement of the sash relative to the frame.

A sack as used herein means a closing member which is adjustable in relation to the frame and which is arranged to close the opening S in the frame. Includes unglazed or partially glazed members such as gas windows or fan windows, doors or sl# windows for opening the top, bottom or part of the sack Fi.

Various types of stays are already known in which arms or mounts and mounting plates or plackets are connected together by a pivot joint. The arms or rods are rotatably connected by weighted grates or plackets.
The sash extends between the sash and the frame, and the sash is supported on each of the two opposing sides by respective stays.

The structure of the stay is that the stay is folded, and when the sash is closed, it is trapped in the groove between the sash, the frame, and the O-gate.
Regarding opening/closing, the stay is designed to act as a lit by the arm or fi link that rotates in relation to the plate or bracket. A link may be constructed from two or more members that are rotated together, and a stay may be formed from one or more sets of arms or links. In use, the sash is free to rotate on such a stay. It's become a trap that I can't do anything about.

The present invention relates in particular to friction stays in which a friction suppressing effect is provided by a riveted pivot joint, in which the rivet is The stem members are secured under pressure to hold them together for controlled nine-turn movement.

These riveted pivot joints are not as simple and easy to manufacture as one might expect.

And mass production and hemming after manufacturing are both important for both use and use (i.e.
There are important issues that arise. Tight tolerances on rivet centers and 11! a special tube layer of material used;
A particular problem in manufacturing arises from the need to maintain the necessary tension in the rivet as well as accuracy in the riveting action.

The problem with using such riveted friction stays is the weight of the f-comb with glass.

and from the i loads that must be supported by the stays, such as the significant wind loads that occur at 9 and # when the stays are stretched supporting the ticks. ! Good weather.

Satsushi's luck is like #lack of maintenance.

There are six abusive conditions that must be endured in use. A special problem is corrosion of riveted pivot joints! or prevent it from weathering and abrasion.

These riveted friction stays must be designed to a range of specifications, which require a variety of dimensions, weights, applications, materials and conditions of use, as well as customer preferences. This becomes an even more critical condition that must be met by the performance of the friction pivot joints of each riveted stay.

It is an object of the present invention to provide a friction stay with a riveted friction pivot joint of simple geometry whereby the riveted joint facilitates the manufacture of the stay with greater precision.

Another object of the present invention is to provide a riveted friction stay whose duppet carpet is clean and stable.

Another object of the invention is to provide a riveted pivot joint with wear resistance JI.
! It has good strength and evenly distributes the load. We also provide a riveted bracing stay configured as shown in Figure 5.

Still another object of the invention is to provide an improved pivot joint that can be easily assembled and stabilized in the mass production of riveted friction stays and for special applications or uses. Including providing special configurations of stays.

According to the present invention, the KIIJ can be rotated together by rivets.
A spacer is placed between the element piece 1 and the second member 5 and the second member 5 to leave a gap between them so that the kojiki member can be moved relative to each other.

Is the rivet smooth with both parts? a cone formed on the surface of the first member for relative rotational movement, the head and shank of the rivet being covered with a Guxtech material having a low-friction first surface on the rivet; The rivet shaft is radially spaced in the 9-conical recess and has an oversized dimension concentric with the penetrating conical recess. A through hole is drilled.

To provide a riveting friction stay configured to fix the tail of the rivet under pressure on the surface of a second member away from the spacing, and to prevent one tail from rotating on the second member (5) with respect to the associated rivet.

According to the invention, a truncated conical head is provided on the rivet and the first
When a conical recess is provided in the stem member, a large load bearing area is provided for uniformly distributed loads. This load-bearing area is one of the critical factors for optimal performance.
It is one.

In terms of conventional dimensions, it is a flat i with a supporting area of 1 m, which is less than Coe.
Standard practice is to use rivets with Is.

Furthermore, when assembling the joint, the provision of a frusto-conical head and conical recess makes it difficult to assemble the joint (as compared to conventional types in which the flat sectioned rivet must be accurately placed in each stem member). Self-centering positioning avoids many of the difficulties in rolling riveted joints. Use KC ^
The strength of the rivet under shear is greater with a truncated conical head than with a flat head, especially at the head where the riveted joint is subject to torsional and bending loads, and in some joints. CI/%ru.

In addition, by providing a plastic cover over the rivet, the metal-to-metal contact between the thread-engaging rivet head and the recessed surface of the O'1 member can be prevented in use due to slipping or deformation of the workpiece material. This leads to a number of problems such as changes in friction control - avoided without the need to provide any interfering low friction.

In addition, the coating on the rivet allows the selection of different metals for the stem part i and the pet, and also reduces the problem of corrosion between the different metals applied to the intermediate surface. Be prepared.

The loop of the rivet through the chain hole allows the above-mentioned self-centering by means of a suitable interlock Is and prevents the guttuster coating on the part of the rivet from being damaged by the edge of the hole.

The present invention is based on Al1. - Applicable to a friction stay having a stay member made of steel.

These members may also be subjected to appropriate surface treatments for corrosion resistance and visibility enhancement.

Preferably, the spacer inserted between the first and outer wing members has a low friction surface for sliding supporting engagement of the first member during rotational movement of the Olil material.

By providing the low-friction IIA surface, wear and tear is avoided, and the support 1i during the pre-propagation movement can be easily seen on the shaft portion during the opening/closing movement of the stay. ! It is provided close to the shaft portion 1 of the 5KIJ bet to reduce the shearing force.

It is convenient for KFi, and it consists of a circle of people. The washer can be made of round metal coated with plastic material.

Does it work fine with the right configuration? &i consists of a plate seated on the male material and having a recess in which the washer is received.

The plate has a significant load-bearing direction t! The plate is positioned over the second member. The plate is preferably made of a low-friction plastic material and has means for positioning the plate against the sag during fixation of the rivet. 5K1.
Supplementary T to 1 member! Equipped with JI tube.

In some applications of friction stays, the plate includes a stop WJt to limit its movement due to the force contact by the Fj member.

With such an arrangement, the pivoting movement of the stay IIjI#i is limited in a simple and quick manner integrated into the pivot joint of the assembly of the stay.

The fixing pressure applied to the rivet is sufficient to provide the joint with the desired friction control in accordance with known methods for different friction stays and their operational applications. The rolling angle, as appropriate to the particular layering and material of the rivet, is taken by rotation and using conventional fastening methods.

According to another aspect of the invention, the member O8 is a truncated cone! !
In the frusto-conical recess, the lower walls of the frusto-conical recess of the tenth member can be received together with frusto-conical spacers inserted in their thresholds.

Preferably, such a configuration is provided where the oversized through-hole in the first member can be formed by a through-hole operation using similar manufacturing techniques used for the snow steering member. Both members are applied to a friction stay made of steel.

The tail of the rivet prevents any rotation associated with the snow steering member, and this can be accomplished in several ways.

In a preferred configuration, the ferrule has a structure to which the tail of the rivet is secured. The rib structure is a series of shibs or sprunches at the bottom of the rivet member, and is located at the edge of the hole in the first member through which the tail of the rivet passes. The IIIk-formed teeth can also form radial serrations.

With such a structure, lips or splines can also be −L<

can provide benefits.

In a variant configuration, the tails of the rivets are arranged within and between the spikes such that upon application of the locking pressure, the spikes bite into the first member, positioning it and the tails securing it to the spiked washers. The spikes and washer can be placed in relation to the second member by inserting the spikes and washers under the tail so as to be forced between them.

The present invention includes rivet positive 6 friction stays of various shapes, but the mounting of snowflakes each adapted for fixing to a fixing frame and a sash is a friction stay having a plate and an arm, one of which is longer than the other.

In the friction stay of the first embodiment, the pivot joint 1 that connects the other ends of the arms S and 6 to the plate 3 is attached in the same way as the - part of the plate 1. Use the same flat yielding washer as in the washer, but with a larger outer diameter. If desired, the base 9 in this pivot joint can be replaced with a flat support plate as described above. You can prepare.

The embodiment of the pond of Book 1i8A will now be described with reference to the associated figures, in which the same reference numerals used with respect to the first embodiment are used to indicate similar parts. The explanation below is brilliant! Discuss the differences between this embodiment and other implementations.

In a second embodiment shown in Figures 4, 5 and 8, a friction stay similar to the first embodiment (a suitable pivot joint 1 is shown). and a spacer 9 consisting of a fastener and a support plate U. The spacer 9 (gray mounting) 1 consists of a grooved section with a groove 3 provided with a DM groove at the bottom. At the bottom of the groove, a longitudinal lip is formed with a spline. For installation, the plate 1 is formed integrally during extrusion molding, and the nine round balls are assembled with an extruded member having splices.

The material of the plate is transformed into a rib or tin iris which prevents the attachment of the rivets 80 to the plate l. Installation is a plate! Supporting spacer 9 on top (gray)i
In order to locate the lVt, the support plate U is mounted on the opposing 7 tsunges 25 that engage the plate 10 end 2 langes:
The arrangement in which the lower part 5IL-mounting engages the plate 1 prevents the support plate u from rotating during the rotational movement of the arm 6.

Modified MljiP of the O-ring implementation shown in the off-diagram and the O-S diagram
- spacer 9 is a flat annular washer d coated with plastic material and made of round metal or plastic material;
Formed from 6. In this variant, the support plate of the spacer is removed and the five pivot points II! I-joints are suitable for use with short, small friction stays that have a relatively low weight-bearing capacity t.

(In the first embodiment shown, this is a mounting made of stainless steel or ambiguous steel, constructed for the manufacture of riveted friction stays with plates and arms. .

A smaller cross-section material can be used for this to give the same load carrying capacity as the aluminum material. These pictures only show a portion of the stay.

That is, the arm 6 and the mounting are shown as part of the plate l'C6. The mounting plate 1 is formed from a groove-shaped cross section with #4 holes extending in the longitudinal direction of the plate 1 under the plate 1.

A KJliil head is formed in the central portion of the plate cover to provide a truncated conical head opening surrounding the through hole 18. The edge of the through hole also has serrations 530 (o 9).
(best shown in the figure) are formed 1, and the tail n of the rivet 8 is fixed within these lines to prevent the rivet from rolling relative to the IK (gray in the installation).

The arm 6 is curved or tenoned adjacent to the end and has a truncated cone aligned with the truncated conical head opening of the rivet 8 which is rounded and coated with plastic. The recessed part rt is equipped with a hole line for nine major carps.

For installation, there is a spacer 9 between the plate 1 and the washer 31 through which the shaft of the rivet passes. It has a special conical shape similar to a type of washer known as a washer. The cone angle of the Waratsuya seal ensures proper thrust and load bearing surfaces (the arms and mountings should be
handle.

As with other embodiments, the rivet is fixed to ensure a residual frictional force in the pivot joint.

The arm is connected to the mounting plate by a rivet. Thrust and load transfer surfaces are important for supporting high loads, and in this example the arms are reciprocally engaged and the attachment is to the plate! Attachment is accomplished by providing two matching recesses at the plate (Cvh).

8, this S indicates a riveted friction stay suitable for use with high weight-bearing capacity, which is a frame K11 with a sash that opens horizontally 11 around the vertical axis.
It has a special use for sashes that make l hang down.

As described above with respect to Figure 1, the stay comprises two arms 5, 6t which are connected together to a rotatable rudder by means of a mounting plate holder 3 and a riveted pivot joint 1. Ar installation and @Vt sash addition on plate 3! The riveting rivets, the pivoting joints 7 and the joints 7 connecting the arms 5, 6 to the frame mounting plate 5 are substantially identical to those described in the 1% implementation. The fundamental difference lies in the provision of special support and stop plates forming part of the spacer.

The support and stop plate 32 is rectangular in horizontal position and includes an arcuate support lip W, the surface of which is in support engagement with the arm i.

The plate depth also has an upright rose Vu.
f) The member is provided with a stop face ink for covering the mmtwa of the rotation of A-1. Furthermore, Great Proverbs has other supporting gII.

The support Ii! II comprises a support for the underside of the arm during the folding movement of the long arm. Preferably, the support and stop plate has screws passing through holes provided therein. The mounting is a plastic molded part that is IK-fixed by a similar fastening member (not shown).

The friction pivot joint in the friction stay is small and has a truncated conical surface of the rivet and a considerable area for load transmission engagement (tension load #C) in the arm. It consists of a simple shape with a !! part" (17h).

Additionally, the use of oversized holes and frustoconical surfaces in the arms allows the rivets to be automatically centered during assembly and fixation (within certain limits and aligned correctly despite any manufacturing tolerances). .Special ec, 9 The overall dimensions of the rivet change due to the glass covering the bet.

The use of a truncated conical head forming a recess in the arm can form a suitable joint in the shed if the head of the rivet is disposed flush with the top surface of the arm and 6 by 5. Take.

This would require that the flat rivet head protrude significantly above the arm or be seated in a special countersink which reduces the overall thickness of the arm over a significant portion where strength is required - otherwise It is distinguished from the shape of a riveted joint.

The above description has been given by way of example only of stay configurations that include riveted friction joints. Other configurations of friction stays may also include such friction pivot joints.

The installation may depend on or be dictated by the type of device in which the plates and stays are used.5 The special application may be made as appropriate to suit the required configuration. It can be formed from the external shape or affiliation.
