Definitions
- the present invention relates to a space heater assembly according to the preamble of claim 1. This space heater is described in the US-A- 2 225 722.
- radiators When using space heaters, such as for example radiators, to heat the interior of a building to a specified temperature, it has been found that the radiator surface temperature may rise sufficiently to burn anyone touching the radiator. This problem is particularly serious when radiators are used in establishments such as hospitals, nurseries or residential homes for the elderly where the occupants are sometimes not very mobile or aware of the danger of touching a radiator.
- the cover may be dimensioned so that when it is in the closed position there is only a very small gap between the support surface and the adjacent part of the cover. This arrangement of the cover and support surface ensures that it is not possible to obtain access to the heater when the cover is in the closed position.
- the said heater takes the form of a hot water radiator, which is provided with one or more control valves for controlling the flow of hot water through said radiator, said control valve or valves being located within said cover when said cover is in the closed position.
- the one or more support brackets are located near the bottom of said heater whereby said cover is moved to its open position by lifting said cover and pivoting the top part thereof away from said support surface.
- the locking device conveniently comprises a screw device carried by said cover and accessible through an aperture therein, said screw device co-acting with an abutment on said one or more support brackets for locking said cover in the closed position.
- said hot water radiator comprises an air venting screw adapted to be operated by a venting key, in which case said screw device of said locking device may also be adapted to be operated by said venting key.
- a bottom cover may be provided which extends from said cover to said floor.
- a radiator assembly of the invention includes a single panel radiator 2 mounted on a wall 4 of a room by two laterally spaced vertical support brackets 6. Two laterally spaced pivot brackets 8 are secured to the wall 4, and each bracket has a vertical slot 10 therein.
- a radiator cover 12 is constructed of sheet metal and comprises a front face 14, an upper panel 16, two side panels 18 and a small lower panel 20.
- a series of vertically spaced grooves 28 extend horizontally along the front face 14, and a series of laterally spaced ventilation grills 30 are formed in the upper panel 16.
- Two inwardly extending tags 34 are formed in the upper part of the front face 14, adjacent to the side panels 18.
- Two restraint chains 36 are mounted to and extend between the tags 34 and corresponding anchor points 38 on the brackets 6. As shown in Figures 2 and 4, the length of these restraint chains 36 defines the position of the cover 12 when in its fully open position.
- the cover 12 is mounted on the pivot brackets 8 by means of two pivot pins 32 which are secured to and extend inwardly from respective side panels 18 to project through the slots 10. These pivot pins 32 are stepped to prevent undue lateral movement of the cover 12.
- a locking screw 40 having a circular stop flange 41 thereon, is in screw-threaded engagement with a housing member 42 secured to the inner surface of the lower part of one of the side panels 18.

- the locking screw head 44 is designed so that it can be rotated by the radiator air venting key so as to withdraw or advance the screw.
- the arrangement of the threaded housing member 42 and the side panel 18 is such that a chamber 47 is formed in which the locking screw head 44 is restrained and allowed only sufficient axial movement for the screw to engage or disengage itself from the pivot bracket 8.
- This feature prevents inadvertent disengagement of the threads of the locking screw 40, and housing member 42.
- the cover 12 is shaped and dimensioned so that the rear edges of the upper panel 16 and the side panels 18 extend almost to the wall 4 when the cover 12 is in the closed position. This prevents people from reaching round the back of the cover 12 and touching the hot surfaces of the radiator, and also reduces the chances of debris falling onto the radiator.
- the radiator control valves and adjacent pipework are also enclosed by the cover 12 when the cover is in its closed position. This prevents people from being burnt by touching the pipework and control valves, and prevents interference with the radiator valve settings.
- the heater may be used with a thermostatically controlled radiator or heater valve.
- the thermostatic control head is mounted remotely from the heater.
- the illustrated radiator assembly has been designed so that the surface temperature of the cover 12 will not exceed 43°C when the radiator 2 is operating at a surface temperature of 75°C.
- the bottom cover 50 is fixed in position by screws which are operated by a vent key as is the locking screw 40.

Abstract
Description
- The present invention relates to a space heater assembly according to the preamble of claim 1. This space heater is described in the US-A- 2 225 722.
- When using space heaters, such as for example radiators, to heat the interior of a building to a specified temperature, it has been found that the radiator surface temperature may rise sufficiently to burn anyone touching the radiator. This problem is particularly serious when radiators are used in establishments such as hospitals, nurseries or residential homes for the elderly where the occupants are sometimes not very mobile or aware of the danger of touching a radiator.
- It is an aim of the invention to alleviate the above-mentioned problem, and according to the present invention there is provided a space heater assembly with the features of claim 1.
- The cover may be dimensioned so that when it is in the closed position there is only a very small gap between the support surface and the adjacent part of the cover. This arrangement of the cover and support surface ensures that it is not possible to obtain access to the heater when the cover is in the closed position.
- In one embodiment of the invention, the said heater takes the form of a hot water radiator, which is provided with one or more control valves for controlling the flow of hot water through said radiator, said control valve or valves being located within said cover when said cover is in the closed position.
- In a preferred arrangement, the one or more support brackets are located near the bottom of said heater whereby said cover is moved to its open position by lifting said cover and pivoting the top part thereof away from said support surface.
- In an especially preferred arrangement the locking device conveniently comprises a screw device carried by said cover and accessible through an aperture therein, said screw device co-acting with an abutment on said one or more support brackets for locking said cover in the closed position.
- It may be arranged that said hot water radiator comprises an air venting screw adapted to be operated by a venting key, in which case said screw device of said locking device may also be adapted to be operated by said venting key.
- In an arrangement in which said assembly is mounted on said support surface in spaced relationship to a floor, a bottom cover may be provided which extends from said cover to said floor.
- It is an important feature of the invention that there is no direct contact between the heater and the cover thereby preventing heat conduction from the heater to the cover.
- One embodiment of the invention will now be described by way of example with reference to the accompanying illustrative diagrammatic drawings in which:-
- Figure 1 is an end view of a radiator assembly of the invention with the cover in its closed position;
- Figure 2 is an end view of the radiator assembly of Figure 1 with the cover in its open position;
- Figure 3 is an end view of the radiator assembly of Figure 1 with the cover in its closed position, and one side of the cover removed;
- Figure 4 is an end view of the radiator assembly of Figure 1 with the cover in its open position, and one side of the cover removed;
- Figure 5 is a plan view of one pivot mounting arrangement of the radiator assembly of Figure 1.
- Figure 6 is a front view of the radiator assembly of Figure 1 with the cover in its closed position; and
- Figure 7 is a plan view from above of the radiator assembly of Figure 1 with the cover in its closed position.
- Referring to the drawings, a radiator assembly of the invention includes a
single panel radiator 2 mounted on awall 4 of a room by two laterally spacedvertical support brackets 6. Two laterally spacedpivot brackets 8 are secured to thewall 4, and each bracket has avertical slot 10 therein. - A
radiator cover 12 is constructed of sheet metal and comprises afront face 14, anupper panel 16, twoside panels 18 and a smalllower panel 20. A series of vertically spacedgrooves 28 extend horizontally along thefront face 14, and a series of laterally spacedventilation grills 30 are formed in theupper panel 16. - Two inwardly extending
tags 34 are formed in the upper part of thefront face 14, adjacent to theside panels 18. Tworestraint chains 36 are mounted to and extend between thetags 34 andcorresponding anchor points 38 on thebrackets 6. As shown in Figures 2 and 4, the length of theserestraint chains 36 defines the position of thecover 12 when in its fully open position. - Referring particularly to Figure 5, the
cover 12 is mounted on thepivot brackets 8 by means of twopivot pins 32 which are secured to and extend inwardly fromrespective side panels 18 to project through theslots 10. Thesepivot pins 32 are stepped to prevent undue lateral movement of thecover 12. - A
locking screw 40, having acircular stop flange 41 thereon, is in screw-threaded engagement with ahousing member 42 secured to the inner surface of the lower part of one of theside panels 18. Access to thehead 44 of the locking screw is provided by anaperture 46 in theside panel 18, theaperture 46 being smaller than theflange 41. - When the
cover 12 is in its closed position, thelocking screw 40 is aligned with anaperture 48 in the associatedpivot bracket 8. When thelocking screw 40 is screwed into its advanced locking position theflange 41 abuts thehousing member 42, and thescrew 40 extends through theaperture 48 to prevent movement of thecover 12 relative to theradiator 2. When it is desired to move thecover 12 to its open position, the locking screw is unscrewed so as to withdraw the screw stem from theaperture 48, until theflange 41 abuts theside panel 18. Thelocking screw head 44 is designed so that it can be rotated by the radiator air venting key so as to withdraw or advance the screw. - The arrangement of the threaded
housing member 42 and theside panel 18 is such that achamber 47 is formed in which thelocking screw head 44 is restrained and allowed only sufficient axial movement for the screw to engage or disengage itself from thepivot bracket 8. - This feature prevents inadvertent disengagement of the threads of the
locking screw 40, andhousing member 42. - The
cover 12 is shaped and dimensioned so that the rear edges of theupper panel 16 and theside panels 18 extend almost to thewall 4 when thecover 12 is in the closed position. This prevents people from reaching round the back of thecover 12 and touching the hot surfaces of the radiator, and also reduces the chances of debris falling onto the radiator. - The radiator control valves and adjacent pipework are also enclosed by the
cover 12 when the cover is in its closed position. This prevents people from being burnt by touching the pipework and control valves, and prevents interference with the radiator valve settings. - The heater may be used with a thermostatically controlled radiator or heater valve. In this arrangement the thermostatic control head is mounted remotely from the heater.
- The illustrated radiator assembly has been designed so that the surface temperature of the
cover 12 will not exceed 43°C when theradiator 2 is operating at a surface temperature of 75°C. - It will be appreciated that in many installations, pipework to the
panel radiator 2 will extend upwards from the floor to the radiator. In the arrangement which has been described, thecover 12 will not fully enclose this pipework. Where it is desired to fully enclose the pipework, the assembly may be provided with abottom cover 50, shown in dashed lines in Fig. 1 which extends between the floor and the bottom of thecover 12. - It may be arranged, for example, that the
bottom cover 50 is fixed in position by screws which are operated by a vent key as is thelocking screw 40. - It is to be understood that this invention is not restricted to a radiator, and is applicable to any suitable type of heater.
