Abstract
A joint (1) for modular displays comprising two or more arms (3, 5, 7), wherein the joint (1) comprises a metal core (9) partially encased by a non-conductive cover means (11), wherein the metal core (9) is exposed through the cover means (11) at one or more contact points (13).
Description
- The present invention relates to a joint for use with modular display systems. In particular, the present invention relates to joints for shop fittings.
- Specialist racks for displaying aquatics such as freshwater and marine livestock; invertebrates; small animals; reptiles and bird displays are known. For example, to allow multiple display tanks to be supported and split over multiple levels a multi-level frame or scaffold is constructed from tubular support elements and angular joints. For example, patent publication FR2599095 describes an angle joint for assembling tubular elements to form frame racks, shelves, and walls etc., which are suitable for displays in shops. The angle joint coupling of FR2599095 consists of a plastic body with a metal reinforcing core. The coupling has two arms perpendicular to each other, with each arm configured to mate with metallic tubular elements that are used to form the uprights and cross-frame supports for building a display. The shape of the tubular element is configured to receive the arm of the coupling, which when inserted abuts an axial seat. The axial seat has projections to interact with the surface of the arms of the coupling to ensure that the coupling strength of the display structure is sufficiently stable.
- When constructing an aquatics display, in addition to the aesthetic appeal, the safety of the construction has to be considered. The tanks within the display include electrical devices such as filters, circulation pumps, heaters and lighting. Care has to be taken to avoid any electricity being carried to the metal components of the display frame, which can cause electric shocks or electrocution. The metal components of the coupling of FR2599095 are encased in plastic to prevent electricity being transmitted through the coupling. Each of the metallic tubular supports are separately earthed. For example, each metallic support is electrically connected to a grounding rod to separately earth each conducting component of the display. However, it has been found that, if there is a fault in any one of the earthing connections, or if any part of the metal frame is not earthed, there is a risk of electrocution. Furthermore, a large display requires a considerable number of connections. As the complexity of displays increases the earthing requirements to avoid the risk of electrocution and ensure a display is safe are also more complicated.
- The present invention sets out to alleviate the problems described above by providing an improved joint.
- In one aspect, the invention provides a joint for modular displays comprising two or more arms, wherein the joint comprises a metal core partially encased by a non-conductive cover means, wherein the metal core is exposed through the cover means at one or more contact points.
- Preferably, the joint further comprises an earthing mans providing an electrical connection between the or each contact point and earth.
- Preferably, each arm of the joint comprises one or more contact points.
- More preferably, each arm of the joint comprises multiple contact points.
- Preferably, the metal core is exposed through apertures in the cover means at the one or more contact points.
- Preferably, each arm is shaped to comprise at least one protrusion, wherein the shape of the arm and the or each protrusion are configured to mate with a tubular support member.
- More preferably, the or each protrusion of the or each arm is exposed through the non-conductive cover means.
- More preferably, each arm comprises a cross-section which is substantially square.
- Optionally, each arm comprises a cross-section which is substantially rectangular.
- In a second aspect, the invention provides a modular platform for supporting a display comprising,
- two or more joints, wherein each joint comprises two or more arms, wherein the joint comprises a metal core partially encased by a non-conductive cover means and the metal core is exposed through the cover means at one or more contact points;
- at least one tubular support member configured to receive one or more arms from one or more joints;
- characterised in that:
- the modular platform comprises an electrical connection means to earth.
- Preferably, the modular platform comprises a single electrical connection means to earth.
- The present invention offers a much safer and simpler construction to earth the modular platform and avoid the risk that anyone that comes into contact with the platform or display could be electrocuted. Essentially, by ensuring that there is electrical connection around the platform, via the joints between each of the support members, the entire modular platform is “live” i.e. electrically conducting. However, the “live” frame is earthed at a single point. By earthing the system through a single point, the installation and maintenance of the earth connection is simplified. Thus, the risk of any point in the modular platform being unintentionally “live” is avoided.
- Preferably, the or each electrical connections means to earth comprises a grounding rod.
- Preferably, the grounding rod comprises a non-corrosive material.
- Preferably, the display comprises one or more aquatics tanks.
- For the purposes of clarity and a concise description, features are described herein as part of the same or separate embodiments; however it will be appreciated that the scope of the invention may include embodiments having combinations of all or some of the features described.
- The invention will now be described by way of example with reference to the accompanying diagrammatic drawings, in which:
-
FIG. 1 is a perspective view of a joint in accordance with the present invention; -
FIG. 2 is a perspective view of a joint in accordance with a second embodiment of the present invention; -
FIG. 3 is a perspective view of a joint in accordance with a third embodiment of the present invention; and -
FIG. 4 is a perspective view of a display platform comprising multiple joints and support members in accordance with a second aspect of the present invention. - Referring to
FIG. 1 , in a first embodiment of the present invention, thejoint 1 comprises threearms arms arm metal core 9, which is covered by a plastic, non-conductive,insulating cover 11. The body of thejoint 1 has multipleelectrical contact points 13 at which themetal core 9 is exposed through theinsulating cover 11. Two of thearms ends plastic cover 11. As shown theends ends third arm 7 of thejoint 1 comprises aprotrusion 15, formed by thecuboidal metal core 9 protruding from theplastic cover 11. The end of the plastic cover from which theprotrusion 15 protrudes is tapered to provideabutment surface 15 a. - In use, the joint of the present invention is a mechanical fitting to retain multiple tubular support members to build a modular display frame. The tubular support members are made of aluminium, steel or a similar material and can be added or removed from the modular display as required. The frame is used to support multiple tanks, such as aquatics tanks, which are stacked on multiple levels. The tubular support members in combination with the joints of the present invention are used to construct a platform or scaffold to securely hold the tanks in place. The tubular support members each comprise a hollow, metal tube having a substantially cuboidal cross-section. The cross-section of each support member is configured to mate h the protrusion and an
arm 7 of thejoint 1. In use, theprotrusion 15 is inserted into the tubular support member to form a “push-fit” connection, whereby the rim of the support member is securely held over theabutment surface 15 a of theplastic cover 11 of thejoint 1. - The tanks, which are supported by the modular display frame include electrical equipment, including filters, circulation pumps, heaters, lighting, and the frame itself may include three-dimensional illuminated displays and/or television screens. The inclusion of electrical equipment requires the display frame an electrical connection between the frame and earth to prevent electrocution when a user comes into contact with any piece of conductive material in the frame. The joints of the present invention are used in a modular system having a single, common earth connection. The entire modular display frame is connected to the same earth i.e. grounding point. Thus, all current that passes around the modular display frame via the conducting tubular support members and the conducting joints is earthed through a single earthing means, such as a wired connection to a metal (copper or steel) grounding rod. When the system is used with aquatics tanks, an earthing rod is connected to the metal modular display frame, and a component part or spoke of the earthing rod is attached and partially immersed in the water container within the tank. Thus, the earthing rod connects the water to “ground”. Each level of the modular display frame, or each individual structure, e.g. each tank, that is held within the frame is earthed to a suitable point
