[0001] 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.
[0002] 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.
[0003] 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.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.
[0012] Referring to the drawings, 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.
[0013] 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.
[0014] 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.
[0015] Referring particularly to Figure 5, 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.
[0016] 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. Access to the head 44 of the locking screw is provided
by an aperture 46 in the side panel 18, the aperture 46 being smaller than the flange
41.
[0017] When the cover 12 is in its closed position, the locking screw 40 is aligned with
an aperture 48 in the associated pivot bracket 8. When the locking screw 40 is screwed
into its advanced locking position the flange 41 abuts the housing member 42, and
the screw 40 extends through the aperture 48 to prevent movement of the cover 12 relative
to the radiator 2. When it is desired to move the cover 12 to its open position, the
locking screw is unscrewed so as to withdraw the screw stem from the aperture 48,
until the flange 41 abuts the side panel 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.
[0018] 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.
[0019] This feature prevents inadvertent disengagement of the threads of the locking screw
40, and housing member 42.
[0020] 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.
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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, the cover 12 will not fully enclose this pipework. Where it is desired
to fully enclose the pipework, the assembly may be provided with a bottom cover 50,
shown in dashed lines in Fig. 1 which extends between the floor and the bottom of
the cover 12.
[0025] 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 the locking screw 40.
[0026] It is to be understood that this invention is not restricted to a radiator, and is
applicable to any suitable type of heater.
