Description

[Detailed description of the invention] The present invention relates to a hinge device and an acoustic panel.

In modern open plan offices and workshops, acoustic panels are often used for sound absorption or other purposes to divide the office or workshop into smaller sections.

Such acoustic panels or other various panels may be interconnected by various fittings, but such fittings may only connect the panels in a certain angular relationship between each adjacent panel. I can't.

Such conventionally known fixtures not only limit the selection of the mounting angle (they are relatively expensive, so they are unfavorable from a cost perspective), but also require careful and careful connection of the panels. It has many drawbacks, such as:

Various attempts have been made to devise fixtures or clamps that allow for free selection of mounting angles between adjacent panels.

For example, a clamp member has been devised in British Patent No. 921,647 which connects folding door pieces using a gear member mounted along the vertical edge of the folding door pieces.

Here, the longitudinal clamp member acts to engage and hold the folding door member and to maintain the gear members in mesh.

However, this construction is not only expensive, but also used for connecting panels, such as acoustic panels, which are often moved according to the required arrangement of panels in open-plan offices or according to the installation of machinery in workshops. It still has the disadvantage of being inconvenient to use.

The object of the present invention is to provide a coupling device, in particular a hinge device, for coupling panels, for example, which eliminates the drawbacks of the previously known coupling devices as described above.

Another object of the present invention is to provide a sound absorbing panel to which the above hinge device is applied.

U.S. Pat. No. 3,114,951 discloses velcro tape (V
A connecting device called elcro Tape (commercial name) has been devised in which a fastener tape made of cloth is used to connect flexible members.

However, this patent does not contain any indication that it can be used to eliminate the disadvantages of known coupling devices used to connect panels; It was not possible to completely eliminate the drawbacks such as limited

In view of the current situation, the hinge device according to the present invention includes at least one set of cloth fastener tapes which are connected by engagement of the plurality of closed loops and cutting loops. Attach directly or indirectly to each target panel, etc. so that one cloth fastener tape adheres to the arcuate surface of the other cloth fastener tape attached to the panel, etc. when the hinge device rotates. ing.

Preferably, both fabric fastener tapes are fixedly arranged on a semi-cylindrical or frame-shaped arcuate surface attached to the edge of an acoustic panel or similar panel.

By effectively using the cloth fastener tape in this way, each panel can be connected without being limited to the mounting angle, and two or more panels can be connected around the same rotation point. .

Furthermore, although the connection force is strong, the panels can be easily attached and detached, so that panels and the like can be installed reliably, easily, and quickly.

The acoustic panel according to the invention also includes a pair of opposing surfaces extending between a pair of vertical edges and an acoustic core housed between the opposing surfaces.

A fabric fastener tape is attached to at least one vertical edge of a set of fabric fastener tapes having any of a number of closed loops and cut loops and connected by engagement thereof.

A set of fabric fastener tapes forms a connection between the acoustic panel and the structure by removably engaging the fabric fastener tape with another fabric fastener tape disposed on another structure. , the transmission of sound through and around the acoustic panel is reduced by the acoustic core and coupling means between the opposing surfaces.

Such sound-absorbing panels can provide the same effects as those of the hinge device, and in addition, small sections with excellent sound-absorbing effects can be easily constructed in offices and workshops.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows two panels, such as an acoustical panel 10, interconnected by the hinge arrangement of the invention.

This hinge device is constructed with two auxiliary velcro tapes 11 and 12 attached to a semi-cylindrical frame member that is fixed to the edges of the acoustic panel.

Opposite types of interconnectable fabric fastener tape, such as velcro tape, are respectively fitted to opposite ends of the acoustic panel 10 shown in FIG.

One velcro tape, for example velcro tape 1
1 is in the form of a closed loop, and the other Velcro tape 12 is in the form of a cut loop, the cut loop forming a small hook for engaging with the closed loop of the corresponding Velcro tape 11.

FIG. 2 shows the shape of two semi-cylindrical frame members 13 placed at the edges of the sound absorbing panel 10. As shown in FIG.

Each frame member 13 is formed in the form of a projecting channel with a semi-circular arcuate portion 14, the edges of which are formed with inwardly directed arms 15, and the mutually facing edges of the arms each have an outwardly directed arm 15 formed thereon. A flange 16 facing toward is integrally provided.

In addition, the flange has a thick walled portion 1 in the shape of a Ushikujiri at its outer end.
7.

This internal thickness mates with the internally bent edge 18 of the substantially U-shaped side member 19, which side member is fixed to the support frame 20 of the acoustic panel, for example by rivets, or which is itself an acoustically absorbing member. It also forms the support frame for the panel.

The thick portion 17 and the inwardly bent edge 18 form the semicircular arcuate portion 14.
Acts as a snap material for insertion of.

Each acoustic panel 10 has a pair of vertical edges (second
A pair of opposing surfaces 24° 25 (only one of which is shown in the figure) and a sound absorbing core 26 housed between them
It is equipped with

The Velcro tapes 11 and 12 are removably engaged with each other to connect the sound absorbing panel 10.

In other words, the Velcro tapes 11 and 12 form a connecting means.

The coupling means together with the sound absorbing core 26 reduce the transmission of sound through and around the sound absorbing panel, thereby improving the sound absorption effect of the sound absorbing panel.

In order to attach the Velcro tape, the inwardly directed arms 15 are preferably slightly bent, as shown at 21.

As can be seen from FIG. 3, a strip of two velcro tapes 12 (or two velcro tapes 11 or one velcro tape 11 and 12 arranged on the same line) is attached to the end of a structure other than a panel, such as a bookshelf 22. can be attached so that the acoustic panel can be attached directly to the bookshelf.

Another application, not shown, is that one type of Vuelcro tape, such as a cut-loop Vuelcro tape, can be placed between two acoustic panels or other panels with a closed-loop Vuelcro tape connected at any mounting angle. Each panel can be connected by attaching it to a part of the rod that acts as a connecting hinge material or by attaching it all around the rod.

An essential feature of the hinge device of the present invention is that, for example, the semi-cylindrical frame member 13 can connect two or more sound absorbing panels to each other around the same pivot point.

For this reason, for example, a 2F sound absorbing panel with Velcro tape 11 attached to each frame material 13,
The frame material 13 can be connected to another panel to which another Velcro tape 12 is attached.

The hinge device according to the invention has been tested and proved to be very strong and particularly resistant to shear forces.

The risk of two or more connected panels being separated by shear forces perpendicular to the axis of the hinge device is therefore extremely small.

This strong resistance of the hinge device makes it possible, for example, as shown in FIG. 1, to attach the acoustic panel to the straight legs 23 without the need for outwardly extending support legs while avoiding the risk of the acoustic panel 10 falling over. I guarantee that.

Although Velcro tape is used in the embodiment, it is needless to say that the present invention is not limited to this, and it is also possible to use a cloth fastener tape that has a closed loop and a cut loop, and these two loops are engaged with each other.
