Description

110387

This invention relates to a profile hinge according to the preamble of claim 1.

The known hinge solutions are characterized in that they consist of a plurality of separate moving parts. In known solutions, the hinge is fastened to the hinged piece by welding or by means of separate fastening means, which are particularly laborious and slow to install on various aluminum or plastic structural profile systems. Welding hinges require special skills and experience to install the hinges to be functional and durable. The so-called piano hinge can only be used in light and structurally limited applications. Plastic boxes and the like 15 typically use solutions in which the hinge is made an integral part of the hinges.

Commonly used solutions of this type are generally not load-bearing and cannot be used in demanding structures. Hinge solutions 20, known as a functional problem, typically have a hinge-to-hinge seal between the hinged pieces and the accuracy of the hinge adjustment required for successful sealing. In demanding loading conditions, a typical problem is to provide effective hinge lubrication.

··· 'In addition, the hinge is generally understood to be a joint between only two pieces' 25, and the movement of the pieces between them is arranged either manually or using, for example, separate hydraulic or pneumatic cylinders.

Known solutions to the complexity and sealing of hinge manufacture and installation 30 are found in GB 1 252 931 and EP application 462 740.

, ·,; Known hinge solutions do not allow versatile, ·· utilization of the hinge so that it can be utilized when required. at the same time to provide mutual movement of the hinged members 2 110387 and as a sealing element between the hinged members, and lubrication of the hinges generally cannot be effected effectively under demanding loading situations. Also, known profile hinge solutions do not disclose means for adjusting 5 profile hinges.

The object of the invention is to eliminate these drawbacks and to provide within the field of application a wide-ranging, completely new type of hinging solution with manufacturing and installation technology so that the hinge structure allows, movement. This object can be achieved in accordance with the invention by combining a previously known profile hinge principle with either a known sealing solution or a new sealing solution by profile design or a combination thereof and by supplying 20 lubricants to one or more openings through the space between profiles. If the lubrication is to be continuous, the lubricant will flow out of the space between the hinge profiles 25 through the respective apertures machined into the respective profiles.

When a hinge is used, the necessary fluid pressure or compressed air is first directed to achieve the mutual movement of the hinged bodies; ' through the openings described in the space between the hinges. The pressure is released through the valves mounted in the selected openings .30. The outer surface of the inner hinge profile and the inner surface of the outer hinge profile are shaped such that the pressure applied between the hinge profiles causes the profiles to rotate relative to each other.

»·· 'The hinge can be restored to its home position by means of • spring elements disposed between the profiles' 35 or at the ends of the profiles, or by other loading of the hinge after depressurization.

i> I i 3 110387

The mutual sealing of the profiles is a functional part of the hinge solution. It is implemented by means of separate sealing profiles mounted on grooves on the outer surface of the inner profile and on the inner surface of the outer profile.

5 In each extreme position, the hinge is sealed so that protrusions are formed at the locations suitable for the outer surface of the inner profile and the inner surface of the outer profile, which, when the hinge reaches its extreme positions, overlap and seal the clearance between the profiles.

10

In the vertical hinging, a plate or bearing is attached to the upper end of the inner profile by means of a screw or other fastening means, which rests on the outer profile and prevents the inner profile from sliding downward through the outer profile. The same object can be achieved by plugging the lower end of the outer profile by means of a screw, clamping sleeve, bearing plug or the like, whereby the inner profile rests on that plug and does not slip downwards.

By dimensioning the outer and inner profiles to different lengths, the profiles and the pieces attached thereto are freely movable relative to each other in the longitudinal direction of the profiles.

More specifically, the hinge according to the invention has. characterized by what is set forth in the characterizing part of claim 1.

The invention will now be described in more detail with reference to the accompanying drawings, which show some embodiments of the hinge structure according to the invention, partly in sectional views.

"· 30 The hinge consists of an inner hinge profile (1) and an outer hinge profile (2), which can be made of aluminum. By extrusion, plastic or other material suitable for each application! ,, *.

Fig. 1 shows a hinge twisted to another extreme position. The inner profile (1) consists of a hub (11), an arc (12) and a fastening part, 110387 (13). The parts (11), (12) and (13) form a continuous and fixed profile (1). The outer profile (2) consists of an arc (22), an arc (23) and a fastener (24). Parts (22), (23 and (24) form a single and integral part of My Profile 2).

Figure 2 shows a hinge twisted at a random angle. Figure 2 illustrates some of the hinge sealing applications provided by the invention. In the embodiment 1, the hinge profile (1) has a sealing groove 10 (15) impressed with a seal made of rubber or other sealing material, which at the second extreme position of the hinge presses against the sealing surface (26) of the profile (2).

15, the profile (2) has similar protrusions (21) and (25) at each end of the part (23). In rotation of the hinge to either end position, the protrusion (14) slides align with either the protrusion (21) or (25). It follows that the profile 20 (1) is wedged tight against the profile (2).

The same result can be obtained by shaping the profiles (1) and (2) slightly elliptical.

In Figure 3, the hinge is pivoted to another extreme position. In Figure 1, the sealing between the profiles (1) and (2) is as follows: The hinge profile (1) has a sealing groove (16) I: treated in part (12). The groove is stamped with a suitable seal (37) made of a sealing material. The seal (37) seals the clearance between the parts (12) and (23), whatever the hinge is twisted in any position.

, t In Figure 3, the section (23) of the profile (2) is an integral part of a larger assembly. Due to the structure provided by the invention, the shape of the outer surface of the part "..." (23) is irrelevant. Figure 3 also shows a method for efficiently lubricating the sliding surfaces of the hinge provided by the invention. Along the lubrication channel (35) »110387, the lubricant can be pressed into the hinge either as needed or continuously. As the hinge turns to the other extreme position, the lubricant is pressed into the clearances (5) between the sliding surfaces. With my gasket 37), if desired, the lubricant can be prevented from leaking outside the hinge. In this case, the ends of the hinge will naturally have to be plugged.

If required by the manufacturing technique or the application, the section (11) of the profile (1) can be made tubular as shown in Fig. 3-10.

The structure according to the invention also enables, if desired, the insertion of a helical or flat spring within the hinge or the control of fluid pressure / compressed air within the hinge to load the profile (1) so that the hinge 15 acts as a spring hinge. The hinge design also allows the hinge to be turned by fluid pressure / compressed air, for example, by directing hydraulic fluid / compressed air through my duct 35) into the hinge. This application could come into play, for example, in some industrial process automations. In this case, the hinge ends 20 naturally also need to be sealed.

In vertical hinging, the upper end support may be provided, for example, as shown in Figure 4. The thrust bearing or the like (8) rests on the frame of the outer profile (2) The bearing (8) is fixed to the inner profile (1) by means of a fastening element (31) and a support plate (34). The plate (34) rests on the upper surface of my thrust bearing 8). The support means prevents the inner profile (1) from passing through the outer profile (2). If the load permits, a straight plate or support plate (34) made of, for example, plastic or other material may be replaced in place of the pressure bearing (8) directly on the frame of the profile (2).

•; Figure 5 shows an alternative support method. Here, the ··. 'Bearing part (7) is mounted inside the outer profile by means of a friction sleeve or> · 35 such as a plate (30) and a fastening element (32) suitable for the outer profile.

• · * * • i »6 110387

At its simplest, the friction sleeve (9) may be a rubber cushion which, by means of the fastening element (32), is compressed so that it spreads and locks into the profile (2).

5, the center (11) of the profile (1) rests on the bearing part (7).

The bearing part (7) is over the shoulder of the adjusting plate (33). The pin portion above the shoulder of the adjusting plate (33) is made centrally with respect to the shoulder of the adjusting plate and passes through the center of the bearing portion (7) into a cavity centrally located in the portion (11) or. The shoulder portion of the adjusting plate (33) is manufactured eccentrically with respect to the shoulder and the upper shoulder portion.

In the embodiment of Figure 5, the pin portion under the adjusting plate (33) passes through the hole in the portion (9). In this embodiment, the bottom of the adjusting plate in the half pin portion is a threaded hole for securing the fastening portion (32). Further, in this embodiment, the part (9) is clamped between the shoulder of the adjusting plate (33) and the plate (30) by means of a fastening element (32) and locked into my profile 2).

20

In the embodiment of Fig. 5, the hinge can be adjusted as follows: loosen the fastening element (32) and pivot the adjusting plate (33).

Then the profile! 1) Moves sideways to your profile! 2) The ratio and hinge adjustment changes.

1 »» '110387 otherwise not necessarily necessary. The need for bearing depends on the materials used in the hinge profiles and the hinge load. If the load permits or it is desired in the horizontal hinging to prevent the longitudinal sliding of the profiles (1) and (2), the ends of the outer profile may be merely plugged or if the use allows it to be left open at one or both ends.

If desired, the invention allows the hinged object to move in the direction of the hinge 10. In this case, the fixedly mounted hinge profile (either (1) or (2)) is the length of the desired movement path, whereby a second profile is attached to the hinged body and at the same time the hinged body slides along the hinged path with the desired hinged profile. 15 An example of this embodiment of the solution is a series of containers having one less lid than the containers. In this case, the container in use is left without a lid while the others are tightly closed. When replacing the receptacle to be put into service, the lid on the receptacle to be put into use is moved in the hinged direction to the receptacle 20 to be decommissioned.

Example 1. Hinging of an aluminum profile door.

The hinge profiles (1) and (2) are made by extrusion of aluminum. The shape of the profiles allows the hinged profiles to be manufactured in standard * * · '25 bars. The profiles are surface treated similarly to the other door structure. Due to the structure of the hinge, the hinges j! may optionally be placed out of sight of the door hinge side of the door and running between the outer surface such as now enabled in hinge design.

-. * 30

The attachment points (13) and (24) of the profiles are shaped such that the hinge profiles are practically connected to the used structural system. The poor sliding properties of the aluminum and the adjustment requirements for the hinges of the application are taken into account in the dimensioning of> .35 profiles with sufficient play (5) so that the play (5) allows the inner profile (1) to move sideways within the outer profile.

t f · · »t *» k i * »* * 110387

The hinged profile bars (1) and (2) are cut to a suitable length according to the load requirements. The outer profile (2) is fixed to the profile system in a manner suitable for the frame frame and the inner profile to the door leaf frame. Because of the need for adjustment of the hinge 5 and the load requirements, the support of both the upper and lower ends of the hinge is handled as shown in Figure 5.

Example 2. Hinging of a sealed plastic box lid.

10 The mechanical load of the hinge is not high, the plastic has good sliding properties and the sealing requirements require hinging along the entire length of the lid.

The hinge is designed such that the outer profile (2) 15 is integral with the box and the inner profile (1) integral with the lid, both over the entire width of the lid and the box. The play between the profiles is dimensioned so that no separate bearing is required.

20 Install the cover by moving it sideways the necessary distance so that the profile (1) goes into my profile 2). When the lid is closed, the outer profile (2) completely fills the groove of the inner profile and the hinge acts as a seal for the box. The cover can be locked in place if desired by plugging the ends of '2) the profile.

Example 3.Hinging a wooden cabinet door designed to be dust-proof.

A: The load on the hinge is lower but the sealing requirement is relatively high.

»*» '* • .30 Hinge profiles made of plastic which are shaped at their attachment points so that the profiles can be used, are used. fasten to hinged parts with screws or similar fasteners. However, the hinged profiles are cut ··· 'across the entire hinged surface so that the inner profile is slightly shorter than the outer profile. Profiles, '**. The mutual dimensioning of (1) and (2) takes into account the clearance required by the mutual rotation of 110107, but the mutual dimensioning prevents my inner profile 1) from moving sideways inside my outer profile 2) since no lateral adjustment is required.

However, the lower end of the outer profile is plugged with the principle 5 shown in Figure 5 so that the pressure bearing (7) has a smooth top and bottom surface, which is exactly the right plastic sheet. Upper bearing is not required.

Numerous solutions differing from the preceding examples can be contemplated within the scope of the invention. It will be appreciated by those skilled in the art that numerous application areas can be found in a variety of application areas, by designing and positioning the profile anchors (13) and (24), integrating the hinge into integral parts to be hinged, resizing the hinge, and interchanging dimensions.

Further, by changing the dimensioning of the hinge profiles, it is possible to adjust the angle of rotation and influence the sealing properties according to the application. The purpose and manufacturing technique also determine whether the inner profile is 20! 1) solid as shown in Figures 1 and 2 or hollow tubular as shown in Figure 3.

The hinge profiles can be attached to the hinged parts. screws or the like, they can be part of the structural system 25 whereby the fastening is compatible with and suitable for the system • 1 or they can be an integral part of the hinged parts.

It will be apparent to one skilled in the art that the invention may vary in detail within the scope of the claims.
