Definitions
- the present invention relates to a concealed-type support arrangement for brackets, consoles, shelves and the like.
- a mounting device in particular for the attachment of shelves to a wall, which comprises a planar mount bracket intended for fastening to a wall and provided, to such purposes, with buttonhole-like slits designed to enable the shelf to be adjusted vertically by means of screws.
- planar bracket defines an engagement edge that extends perpendicularly relative to the plane of the same bracket and is provided with a slot.
- the device further comprises an L-shaped plate that is associated to the bracket with the help of the slot and has a shorter length than the slot itself. This plate is adapted to engage a support shank provided in a substantially perpendicular manner on the bracket.
- the position of the plate and, as a result, the support shank is adjustable in a direction extending parallel to the plane of the bracket along the length of the slot.
- the torque generated by the weight of the support shank acts on the plate so as to immobilize, i.e. retain the same plate in the desired position, whereas - in view of enabling the plate to be displaced translationally and the position of the support shank to be adjusted along the plane of the mounting bracket - a force is required to be applied upon the shank, which must be such as to be at least adapted to countervail, i.e. overcome the torque generated by the weight of the support shank.
- the above-cited plate further comprises two dowels, which - by acting upon the bracket - exert a force onto the plate, thereby causing it to open out relative to the same bracket so as to correspondingly adjust the inclination of the support shank relative to the plane of the bracket.
- This prior-art device has a major drawback in that, for the support arm to be adjusted horizontally, the need arises for quite complicated an operation to be performed that practically does not allow the position of the same support arm to be accurately, i.e. finely adjusted along the mounting bracket to any adequate extent.
- the shelf or the like, to be removed from the related support arm and an appropriate force to be exerted upon the shank so as to counterbalance, and overcome, the torque generated by the weight of the same shank, so as to cause the plate to disengage and be displaced along the slot into the desired position.
- the shelf must be mounted in place again and the adjustment be checked for adequateness, wherein it can be most readily understood that such operation has to be repeated, i.e. performed again and again until an adequate adjustment is eventually achieved.
- Another purpose of the present invention is to provide an arrangement of the above-indicated kind, which is simple in construction, reliable in practical use, and capable of being manufactured at fully competitive costs.
- the concealed-type support arrangement for brackets, consoles, shelves, and the like according to a first embodiment of the present invention - as indicated generally at 101 in the Figures - comprises a longitudinal mounting bracket 102 adapted to be attached to a wall, a support arm 103 capable of being inserted in a receptacle provided in a shelf 104, adjustment means for adjusting the position of the support arm 103 relative to the mounting bracket 102.
- Such adjustment means comprise a movable member 105 accommodated in a housing body 106 formed by the bracket 102 itself and adapted to be associated to the arm 103, a first threaded member 107 engaging said movable member 105 and adapted to cooperate with the housing body 106 to translationally displace said movable member 105 within the housing body 106 along a longitudinal axis 108 so as to adjust the position of the arm 103 along the bracket 102, a second threaded member 109 engaging said movable member 105 and adapted to cooperate with the housing body 106 to cause said movable member 105 to rotate about said longitudinal axis 108 within the housing body 106 so as to adjust the inclination of the support arm 103 relative to the mounting bracket 102.
- the mounting bracket 102 comprises an element having an elongated shape extending in a longitudinal direction, which is provided - at each end portion thereof - with a slot-like perforation 110 for the bracket 102 to be able to be secured to the wall by means of appropriate screws 111.
- Such slot-like perforations 110 are so shaped as to enable the vertical position of the bracket 102 and, as a result, the support arm 103 to be adjusted relative to the screws 111 fitted into the wall, so as to have the vertical position of the shelf adjusted as desired.
- the mounting bracket 102 forms integrally therewith, i.e. in a single-piece unitary construction with the same bracket, the above-indicated housing body 106, which defines a cavity adapted to accommodate the movable member 105.
- the housing body 106 protrudes from the plane of the bracket and is adapted to be received in an appropriate receptacle provided within the thickness of the shelf when the latter is mounted in position against the wall.
- the above-cited housing body 106 is provided - on a front portion thereof - with a front slot-like aperture 112, through which access can be gained to an internally threaded bush 113, which is provided on the movable member 105, and which is adapted to receive and engage with a corresponding threaded end portion 114 of the support arm 103, in such a manner as to secure the same arm to the bracket 102.
- the movable member 105 and the housing body 106 are so shaped as to ensure that the movable member is adapted to slide within the housing body along a longitudinal axis 108 extending parallel to the longitudinal extension plane of the bracket 102, and is further adapted to rotate about said longitudinal axis 108, again within the housing body 106.
- the movable member 105 defines a surface 115 having a circular contour and adapted to slide along and rotate about an inner, correspondingly shaped surface of the housing body.
- the first threaded member 107 is linked to the housing body 106 in a longitudinal position so as to be able to engage a threaded bore 116 provided in the movable member 105, and drive in this way the movable member 105 into moving, i.e. displacing along the longitudinal axis 108 inside the housing body 106.
- the first threaded member 107 is free to rotate about the longitudinal axis 8 jointly with the movable member 105.
- the movable member 105 defines mutually aligned side studs 117 that protrude from the movable member 105 so as to extend along the longitudinal axis 108 in view of facilitating rotation of the movable member 105 about said longitudinal axis 108.
- the threaded bore 116 is provided in one of these studs 117.
- the first threaded member 107 comprises a screw featuring a head that is rotatably retained in a receptacle 118 provided in the housing body 106 and is accessible from the outside through an appropriate aperture 119 for it to be actuated by means of a tool.
- the movable member 105 defines a threaded through-cavity 120, in which there engages the second threaded member 109 so as to cause the movable member 105 to rotate about the longitudinal axis 108.
- the housing body 106 is further provided with a slot-like perforation 121 on the lower side thereof, through which the second threaded member 109 is accessible from the outside for it to be actuated.
- Such second threaded member 109 is capable of being screwed into said cavity 120 so as to move into abutment against an inner wall 122 of the housing body 106, thereby stopping the second threaded member 109 and positively preventing it from moving translationally in a direction extending substantially across the longitudinal axis 108.
- the second threaded member 109 comprises a dowel that is accessible from below, relative to the bracket attached to the wall, through the above-cited lower slot-like perforation 121.
- the threaded cavity 120 extends along an axis 123 that is inclined relative to the longitudinal axis 108.
- the inclined axis 123 forms an angle with the vertical direction, so that the axis of the dowel extends downwards away from the wall.
- the movable member 105 is capable of pivotally oscillating about the longitudinal axis 108 between a first position, in which the arm 103 extends horizontally relative to the wall, and a second position, in which the arm 103 is slightly inclined upwards relative to the horizontal direction.
- the inventive support arrangement enables the inclination of the arm 103 relative to the mounting bracket 102 to be adjusted while the shelf 104 is partially mounted, i.e. with the shelf 104 that is just slightly moved away from the wall so that the second threaded member 109 is capable of been reached with a tool for proper actuation.
- the shelf is specially provided with an appropriate bore 124, the possibility is given for the inclination of the arm 103 relative to the mounting bracket 102 to be adjusted while the shelf 104 is fully mounted, i.e. abutting tightly against the wall as shown in Figure 105.
- the inclination of the second threaded member 109 makes it particularly simple to perform the above-described adjustment operation, since it allows for convenient handling of the tool as suitably spaced apart from the wall.
- the concealed-type support arrangement for brackets, consoles, shelves, and the like according to a second embodiment of the present invention - as indicated generally at 201 in the Figures 8-13 - comprises a longitudinal mounting bracket 202 adapted to be attached to a wall, a transverse support arm 203 capable of being inserted in a receptacle provided in a shelf 204, adjustment means for adjusting the position of the support arm 203 relative to the mounting bracket 202.
- the shelf support arrangement further comprises a movable member 205 accommodated in a housing body 206 defined by the mounting bracket 202 and provided with a threaded bore 207 to rotatably engage a corresponding threaded portion 208 of the arm 203, coupling means 209 to block, i.e. firmly retain the arm 203 in the bracket 202 transversally relative thereto, a threaded member 210 engaging said movable member 205 and adapted to cooperate with the housing body 206 to longitudinally guide, i.e.
- the mounting bracket 202 is comprised of an elongated body that extends in a longitudinal direction A running parallel to the wall to which the mounting bracket 202 is due to be attached, wherein said elongated body is provided - at each end portion thereof - with a slot-like perforation 212 for the bracket 202 to be able to be secured to the wall by means of appropriate screws 213.
- Such slot-like perforations 212 are so shaped as to enable the vertical position of the bracket 202 and, as a result, the support arm 203 to be adjusted relative to the screws 213 fitted into the wall, so as to have the vertical position of the shelf 204 adjusted accordingly.
- the mounting bracket 202 forms integrally therewith, i.e. in a single-piece unitary construction with the same bracket, the above-indicated housing body 206, which defines a cavity adapted to accommodate the movable member 205.
- the housing body 206 protrudes from the attachment wall, and is adapted to be received in an appropriate receptacle provided within the thickness of the shelf, when the mounting bracket 202 is mounted in position against the wall.
- the mounting bracket 202 is provided with a front slot-like aperture 214, through which access can be gained into the threaded bore 207 of the movable member 205 to let the threaded portion 8 of the support arm engage said bore.
- the slot-like aperture 214 is so shaped as to further enable the arm 203 to displace longitudinally and be inclined according to the related adjustment needs.
- the arm 203 as associated to the movable member 205 and the mounting bracket 202, extends in a transversal direction B running perpendicular to the wall which the longitudinal mounting bracket 202 is due to be attached to.
- the threaded bore 207 is a through-bore, so that an end portion 215 of the arm 203 is capable of extending throughout the movable member 205 to eventually protrude therefrom so as to rotatably engage the coupling means 209.
- the coupling means 209 comprise an abutting member 216, which is constituted by a washer in the particular embodiment being discussed, and which is adapted to rotatably receive the end portion 215 of the arm 203 and position itself into abutment against the body of the mounting bracket 202 in correspondence to a receptacle 217 opposing the slot-like aperture 214.
- the coupling means 209 further comprise an interference member 218, which is constituted by a kind of snap ring in the particular embodiment being discussed, and which is adapted to engage a groove 219 provided on the end portion 215 of the arm 203, as well as to come into contact with the abutting member 216 to prevent the end portion 215 of the arm 203 from sliding or displacing transversally relative to the abutting member 216 and, as a result, to retain the arm 203 transversally relative to the mounting bracket 202.
- an interference member 218, which is constituted by a kind of snap ring in the particular embodiment being discussed, and which is adapted to engage a groove 219 provided on the end portion 215 of the arm 203, as well as to come into contact with the abutting member 216 to prevent the end portion 215 of the arm 203 from sliding or displacing transversally relative to the abutting member 216 and, as a result, to retain the arm 203 transversally relative to the mounting bracket 202.
- the abutting member 216 is capable of sliding longitudinally along the receptacle 217 provided in the mounting bracket 202 so as to allow the arm 203 to displace longitudinally along the same bracket 202, whereas the interference member 218, which is elastically deformable, allows the end portion 215 to be inclined relative to the abutting member 216 and, as a result, the arm 203 to be inclined relative to the bracket 202.
- the coupling means 209 allow the arm 203 to rotate about its own axis, so that the threaded portion 208 of the arm 203, when the latter is rotated, acts upon the threaded bore 207 to thereby drive the movable member 205 into displacing transversally, so as this will be described in greater detail further on.
- the threaded member 210 is linked to the interior of the housing body 206 in a fixed longitudinal position, i.e. is retained longitudinally relative to the bracket 202, so as to be able to engage an internally threaded bush 220 of the movable member 205, and drive in this way the movable member 205 into moving, i.e. displacing longitudinally within the housing body 206.
- the threaded member 210 is free to slide transversally within the housing body 206 and to rotate about its own axis jointly with the movable member 205.
- the threaded member 210 comprises a head 221 that is secured longitudinally in a transversally extending guide member 222 provided in the housing body 206 and defined by a pair of parallel edges 223 that retain such head longitudinally, while allowing it to both slide transversally along the guide member 222 and rotate on itself.
- An aperture 224 which is specially provided in the body of the mounting bracket 202 to such purpose, allows access to be gained to the head 221 of the threaded member 210 for it to be able to be actuated by means of a tool. Screwing the threaded member 210 in and out causes the movable member 205 to slide, i.e. displace longitudinally within the housing body 206 and, as a result, the arm 203 to displace longitudinally relative to the mounting bracket 202, owing to the arm 203 being firmly joined with the movable member 205.
- the abutting member 216 which is engaged by the end portion 215 of the support arm 203, is caused by the same arm 203 to displace in the longitudinal direction A, so as to slide along the receptacle 217 of the mounting bracket 202.
- the support arm 203 is firmly retained against the body of the mounting bracket 202 transversally by the coupling means 209, but is free to rotate about its own axis. Therefore, when the support arm 203 is rotated by a user to adjustment purposes, this will cause - owing to the screw-nut screw coupling existing between the threaded portion 208 of the arm 203 and the threaded bore 207 of the movable member 205 - the movable member 205 to displace in the transverse direction B.
- the guide means 211 provided in the housing body 206 are adapted to partially rotate the movable member 205 about the longitudinal axis C while the movable member 205 itself is displacing transversally, so as to cause the arm 203 to incline relative to the mounting bracket 202.
- the guide means 211 comprise at least one inclined plane or, more preferably, a pair of inclined planes provided in the housing body 206 in proximity of the front slot-like aperture 214 of the mounting bracket 202.
- These inclined planes are adapted to cooperate with the movable member 205, and in particular with concavely contoured surfaces 225 provided thereon, so that the movable member 205, when moving transversally towards the front slot-like aperture 214, is able to slide along the inclined planes so as to be rotated by as wide an angle as great the displacement of the movable member 205 is, thereby enabling the support arm 203 to be finely adjusted owing to the support arm itself being firmly associated to the movable member 205 to move jointly therewith.
- the movable member 205 is capable of sliding transversally within the housing body 206 between a first extreme, i.e. end position, in which the support arm 203 extends horizontally from the bracket 202 when the latter is attached to the wall, and a second extreme, i.e. end position, in which the support arm 203 is inclined upwards by a greatest possible angle relative to the bracket 202.
- any adjustment of the position of the support arm 203 can be performed without any need arising for the supported shelf to be completely removed from the support arm itself, since it is sufficient for the same shelf to be just slightly spaced apart, i.e. moved away from the mounting bracket for the threaded member to be able to be actuated and, as a result, the arm adjusted accordingly.
- the concealed-type support arrangement for brackets, consoles, shelves, and the like according to a third embodiment of the present invention - as indicated generally at 301 in the Figures 14-20 - comprises a longitudinal mounting bracket 302 adapted to be attached to a wall 303, a transverse support arm 304 capable of being inserted in a receptacle provided in a shelf 305, adjustment means for adjusting the position of the support arm 304 relative to the mounting bracket 302.
- the shelf support arrangement further comprises a movable member 306 accommodated in a housing body 307 defined by the mounting bracket 302 and provided with a threaded bore 308 to rotatably engage a corresponding threaded portion 309 of the arm 304, coupling means 310 to block, i.e. firmly retain the arm 304 in the bracket 302 transversally relative thereto.
- a first longitudinally extending serration 311 is provided on said movable member 306 so as to be adapted to cooperate with a second longitudinally extending serration 312 provided inside said housing body 307 for the longitudinal position of the movable member 306 within the housing body 307 and, as a result, the arm 304 along the mounting bracket 302 to be able to be adjusted.
- Guide means 313 are provided in said housing body 307 so as to be adapted to cooperate with said movable member 306; said arm 304, through said threaded portion 309 thereof, is adapted to cause said movable member 306 to slide transversally along said guide means 313 so that said movable member 306 is rotated about a longitudinal axis C, thereby adjusting the inclination of the support arm 304 relative to the mounting bracket 302.
- the mounting bracket 302 is comprised of an elongated body that extends in a longitudinal direction A running parallel to the wall 303, which the mounting bracket 302 is due to be attached to, wherein said elongated body is provided - at each end portion thereof - with a slot-like perforation 314 for the bracket 302 to be able to be secured to the wall 303 by means of appropriate screws 315.
- Such slot-like perforations 314 are so shaped as to enable the vertical position of the bracket 302 and, as a result, the support arm 304 to be adjusted relative to the screws 315 fitted into the wall, so as to have the vertical position of the shelf 305 adjusted accordingly.
- the mounting bracket 302 forms integrally therewith, i.e. in a single-piece unitary construction with the same bracket, the above-indicated housing body 307, which defines internally a cavity 316 adapted to accommodate the movable member 306.
- the housing body 307 protrudes from the attachment wall 303, and is adapted to be received in an appropriate receptacle provided within the thickness of the shelf 305, when the mounting bracket 302 is mounted in position against the wall.
- the mounting bracket 302 On a front portion thereof, the mounting bracket 302 is provided with a front slot-like aperture 317, through which access can be gained into the threaded bore 308 of the movable member 306 to let the threaded portion 309 of the support arm 304 engage said bore.
- the slot-like aperture 317 is so shaped as to further enable the arm 304 to displace longitudinally and be inclined according to the related adjustment needs.
- the arm 304, as associated to the movable member 306 and the mounting bracket 302 extends in a transversal direction B running perpendicular to the wall 303, which the longitudinal mounting bracket 302 is due to be attached to, as well as perpendicular to the axis A, along which the body of the mounting bracket 302 extends.
- the threaded bore 308 is a through-bore, so that an end portion 318 of the arm 304 is capable of extending throughout the movable member 306 to eventually protrude therefrom so as to rotatably engage the coupling means 310.
- the coupling means 310 comprise an abutting member 319, which is constituted by a washer in the particular embodiment being discussed, and which is adapted to rotatably receive the end portion 318 of the arm 304 and position itself into abutment against the body of the mounting bracket 302 in correspondence to a receptacle 320 opposing the slot-like aperture 317.
- the coupling means 10 further comprise an interference member 321, which is constituted by a kind of snap ring in the particular embodiment being discussed, and which is adapted to engage a groove 322 provided on the end portion 318 of the arm 304, as well as to come into contact with the abutting member 319 to prevent the end portion 318 of the arm 304 from sliding or displacing transversally, i.e. along the axis B, relative to the abutting member 319 and, as a result, to positively retain the arm 304 transversally relative to the mounting bracket 302.
- the abutting member 319 is capable of sliding longitudinally along the receptacle 320 provided in the mounting bracket 302 so as to allow the arm 304 to displace longitudinally along the same bracket 302, whereas the interference member 321, which is elastically deformable, allows the end portion 318 to be inclined relative to the abutting member 319 and, as a result, the arm 304 to be inclined relative to the bracket 302.
- the coupling means 310 allow the arm 304 to rotate about its own axis, so that the threaded portion 309 of the arm 304, when the latter is rotated, acts upon the threaded bore 308 to thereby drive the movable member 306 into displacing transversally, so as this will be described in greater detail further on.
- the movable member 306 comprises a first serration 311 that extends longitudinally along an upper portion of the movable member 306.
- This first serration 311 is substantially provided by correspondingly machining an upper surface of the movable member 306 so as to form a plurality of projecting teeth following each other in a regular sequence in a longitudinal direction running parallel to the axis A along which the body of the mounting bracket 302 extends, as this is clearly shown in Figures 14,15 and 19.
- the housing body 307 comprises a second serration 312 provided on an inner surface of the same housing body 307, wherein such second serration 312 is provided so as to extend in correspondence to the first serration of the movable member 306, in a position lying substantially above said first serration 311.
- this second serration 312 of the housing body 307 is formed of a plurality of projecting teeth that follow each other in a regular sequence in a longitudinal direction along the axis A, i.e. the axis along which the body of the mounting bracket 302 extends.
- the teeth of the two above-cited serrations 311 and 312 are so shaped as to be able to mesh with each other.
- the movable member 306 is adapted to be moved, i.e. displaced longitudinally within the housing body 307 to select a desired position of the arm 304 relative to the mounting bracket 302.
- the first serration 311 on the movable member 306 is designed to slide along the second serration 312 on the housing body 307 and be then stopped and retained in the selected longitudinal position by virtue of the torque generated by weight-force of the arm 304 and the shelf 305 mounted on such arm 304.
- the torque generated by the weight of the arm 304 causes the teeth of the serrations 311, 312 to engage each other, thereby positively preventing the first serration 311 from slipping or sliding longitudinally on and relative to the second serration 312, and - as a result - immobilizing the movable member 306 within the housing body 307 in the longitudinal position selected by the user.
- the user grasps the arm 304 and counterbalances the torque generated by the weight of the arm 304 so as to enable the serrations 311, 312 to disengage each other and, as a result, the movable member 306 to slide longitudinally within the housing body 307.
- the user Upon reaching the most suitable longitudinal position of the movable member 306 selected in view of enabling the arm 304 and, ultimately, the shelf 305 to be positioned in the correct manner as desired, the user then lets go of, i.e. releases the arm 304, the weight-force of which will therefore cause the teeth of the serrations 311, 312 to mutually engage by meshing again with each other, thereby immobilizing the movable member 306 longitudinally within the housing body 307 and holding the arm 304 firmly in the selected position thereof.
- the abutting member 319 which is engaged by the end portion 318 of the support arm 304, is adapted to slide along the receptacle 320 of the mounting bracket 302, as moved by the same arm 304 to displace in the longitudinal direction A, when the position of the arm 304 is being adjusted by the user.
- the support arm 304 is firmly retained transversally against the body of the mounting bracket 302 by the coupling means 310, but is free to rotate about its own axis. Therefore, when the support arm 304 is rotated by a user to adjustment purposes, this - owing to the screw-nut screw coupling existing between the threaded portion 309 of the arm 304 and the threaded bore 308 of the movable member 306 - will cause the movable member 306 to displace in the transverse direction, i.e. along the axis B.
- the guide means 313 provided in the housing body 307 are adapted to partially rotate the movable member 306 about a longitudinal axis C while the movable member 306 itself is displacing transversally, so as to cause the arm 304 to incline relative to the mounting bracket 302.
- the guide means 313 comprise at least one inclined plane or, more preferably, a pair of inclined planes provided in the housing body 307. These inclined planes are adapted to cooperate with the movable member 306, and in particular with side portions 323 thereof, so that the movable member 306, when moving transversally towards the front button-like aperture 317, is able to slide along the inclined planes, through the side portions 323, so as to be rotated by as wide an angle as great the displacement of the movable member 306 is, thereby enabling the support arm 304 to be finely adjusted into the desired position, owing to the support arm itself being firmly associated to the movable member 306 to move jointly therewith.
- the teeth of the serrations 311, 312 are provided in such a manner as to enable the movable member 306 to concurrently move, i.e. slide transversally within the housing body 307 and rotate about the axis C.
- the housing body 307 is provided laterally with apertures 324, through which the side portions 323 of the movable member 306 are received so as to allow for free movement of the movable member 306 transversally and related inclination of the arm 304.
- the movable member 306 is capable of sliding transversally within the housing body 307 between a first extreme, i.e. end position, shown in Figure 17, in which the support arm 304 extends horizontally from the bracket 302 when the latter is attached to the wall 303, and a second extreme, i.e. end position, shown in Figure 18, in which the support arm 304 is inclined upwards by a greatest possible angle relative to the bracket 302.
- adjusting the inclination of the support arm 304 requires a user to simply rotate the arm in a given direction, relative to the axis B, to raise, i.e. incline the arm 304 upwards, and rotate the same arm 304 in the opposite direction to bring the arm 304 back into the horizontal position thereof.
- rotating in the clockwise direction will enable the arm to be inclined upwards, while rotating in the counter-clockwise direction will cause the same arm to be moved back into the horizontal position thereof.
- any adjustment of the position of the support arm 304 can be performed without any need arising for the supported shelf to be completely removed from the support arm itself, since it is sufficient for the same shelf to be just slightly spaced apart, i.e. moved away from the mounting bracket for the arm 304 to be able to be actuated.

Abstract
Description
- The present invention relates to a concealed-type support arrangement for brackets, consoles, shelves and the like.
- Disclosed in the
French patent publication no. FR 2 701 520 - The position of the plate and, as a result, the support shank is adjustable in a direction extending parallel to the plane of the bracket along the length of the slot. The torque generated by the weight of the support shank acts on the plate so as to immobilize, i.e. retain the same plate in the desired position, whereas - in view of enabling the plate to be displaced translationally and the position of the support shank to be adjusted along the plane of the mounting bracket - a force is required to be applied upon the shank, which must be such as to be at least adapted to countervail, i.e. overcome the torque generated by the weight of the support shank.
- The above-cited plate further comprises two dowels, which - by acting upon the bracket - exert a force onto the plate, thereby causing it to open out relative to the same bracket so as to correspondingly adjust the inclination of the support shank relative to the plane of the bracket.
- This prior-art device, as it has been described above, has a major drawback in that, for the support arm to be adjusted horizontally, the need arises for quite complicated an operation to be performed that practically does not allow the position of the same support arm to be accurately, i.e. finely adjusted along the mounting bracket to any adequate extent.
- For the position of the support arm to be adjusted horizontally, the need in fact arises for the shelf, or the like, to be removed from the related support arm and an appropriate force to be exerted upon the shank so as to counterbalance, and overcome, the torque generated by the weight of the same shank, so as to cause the plate to disengage and be displaced along the slot into the desired position. Thereupon, the shelf must be mounted in place again and the adjustment be checked for adequateness, wherein it can be most readily understood that such operation has to be repeated, i.e. performed again and again until an adequate adjustment is eventually achieved.
- Another major drawback generally encountered in the above-cited prior art lies in the fact that adjusting the inclination of the support shank relative to the mounting bracket has to be performed by actuating both dowels correspondingly. This implies a lot of time being required to complete the operation, actually, and further results in an inadequately accurate, scarcely reproducible adjustment being generally obtained, since the possibility for the two dowels to be actuated in exactly the same manner certainly is a most unlikely occurrence.
- In addition, owing to such two dowels being provided to extend perpendicularly relative to the mounting bracket, for them to be able to be actuated the need arises for the shelf to be completely removed off the related support shank, the dowels to be actuated, the shelf to be mounted back on the support shank, the just performed adjustment to be checked for adequateness, and the whole procedure to be possibly repeated until the desired adjustment is eventually achieved.
- It is therefore an object of the present invention to provide a concealed-type support arrangement for brackets, consoles, shelves, and the like, which is effective in doing away with the drawbacks and disadvantages of prior-art devices of the kind as described above.
- Within this general object, it is a purpose of the present invention to provide an arrangement of the above-indicated kind, in which the adjustment of the support shank relative to the mounting bracket can be done in a simple, quick and most effective manner.
- Another purpose of the present invention is to provide an arrangement of the above-indicated kind, which is simple in construction, reliable in practical use, and capable of being manufactured at fully competitive costs.
- According to the present invention, these aims, along with further ones that will become apparent from the following disclosure, are reached in an arrangement incorporating the features as defined and recited in the claims 1 et seq. appended hereto.

- With reference to the Figures 1-7, the concealed-type support arrangement for brackets, consoles, shelves, and the like according to a first embodiment of the present invention - as indicated generally at 101 in the Figures - comprises a
longitudinal mounting bracket 102 adapted to be attached to a wall, asupport arm 103 capable of being inserted in a receptacle provided in ashelf 104, adjustment means for adjusting the position of thesupport arm 103 relative to themounting bracket 102. - Such adjustment means comprise a
movable member 105 accommodated in ahousing body 106 formed by thebracket 102 itself and adapted to be associated to thearm 103, a first threadedmember 107 engaging saidmovable member 105 and adapted to cooperate with thehousing body 106 to translationally displace saidmovable member 105 within thehousing body 106 along alongitudinal axis 108 so as to adjust the position of thearm 103 along thebracket 102, a second threadedmember 109 engaging saidmovable member 105 and adapted to cooperate with thehousing body 106 to cause saidmovable member 105 to rotate about saidlongitudinal axis 108 within thehousing body 106 so as to adjust the inclination of thesupport arm 103 relative to themounting bracket 102. - The
mounting bracket 102 comprises an element having an elongated shape extending in a longitudinal direction, which is provided - at each end portion thereof - with a slot-like perforation 110 for thebracket 102 to be able to be secured to the wall by means ofappropriate screws 111. Such slot-like perforations 110 are so shaped as to enable the vertical position of thebracket 102 and, as a result, thesupport arm 103 to be adjusted relative to thescrews 111 fitted into the wall, so as to have the vertical position of the shelf adjusted as desired. - The
mounting bracket 102 forms integrally therewith, i.e. in a single-piece unitary construction with the same bracket, the above-indicatedhousing body 106, which defines a cavity adapted to accommodate themovable member 105. Thehousing body 106 protrudes from the plane of the bracket and is adapted to be received in an appropriate receptacle provided within the thickness of the shelf when the latter is mounted in position against the wall. - The above-cited
housing body 106 is provided - on a front portion thereof - with a front slot-like aperture 112, through which access can be gained to an internally threadedbush 113, which is provided on themovable member 105, and which is adapted to receive and engage with a corresponding threadedend portion 114 of thesupport arm 103, in such a manner as to secure the same arm to thebracket 102. - The
movable member 105 and thehousing body 106 are so shaped as to ensure that the movable member is adapted to slide within the housing body along alongitudinal axis 108 extending parallel to the longitudinal extension plane of thebracket 102, and is further adapted to rotate about saidlongitudinal axis 108, again within thehousing body 106. - In particular, on the front side thereof the
movable member 105 defines asurface 115 having a circular contour and adapted to slide along and rotate about an inner, correspondingly shaped surface of the housing body. - The first threaded
member 107 is linked to thehousing body 106 in a longitudinal position so as to be able to engage a threadedbore 116 provided in themovable member 105, and drive in this way themovable member 105 into moving, i.e. displacing along thelongitudinal axis 108 inside thehousing body 106. - The first threaded
member 107 is free to rotate about the longitudinal axis 8 jointly with themovable member 105. - Advantageously, the
movable member 105 defines mutually alignedside studs 117 that protrude from themovable member 105 so as to extend along thelongitudinal axis 108 in view of facilitating rotation of themovable member 105 about saidlongitudinal axis 108. The threadedbore 116 is provided in one of thesestuds 117. In an advantageous manner, the first threadedmember 107 comprises a screw featuring a head that is rotatably retained in areceptacle 118 provided in thehousing body 106 and is accessible from the outside through anappropriate aperture 119 for it to be actuated by means of a tool. The shank of this screw engages the threadedbore 116 provided in one of saidstuds 117 so that screwing this screw in and out causes themovable member 105 to slide, i.e. displace along thelongitudinal axis 108, since the screw itself is positively prevented from displacing longitudinally relative to thehousing body 106. - The
movable member 105 defines a threaded through-cavity 120, in which there engages the second threadedmember 109 so as to cause themovable member 105 to rotate about thelongitudinal axis 108. - The
housing body 106 is further provided with a slot-like perforation 121 on the lower side thereof, through which the second threadedmember 109 is accessible from the outside for it to be actuated. Such second threadedmember 109 is capable of being screwed into saidcavity 120 so as to move into abutment against aninner wall 122 of thehousing body 106, thereby stopping the second threadedmember 109 and positively preventing it from moving translationally in a direction extending substantially across thelongitudinal axis 108. Screwing in the second threadedmember 109, when the latter is blocked in position, causes themovable member 105 to be driven into rotating about thelongitudinal axis 108 thanks to the screw-nut screw coupling established between the second threadedmember 109 and themovable member 105. In the embodiment being discussed, the second threadedmember 109 comprises a dowel that is accessible from below, relative to the bracket attached to the wall, through the above-cited lower slot-like perforation 121. Advantageously, the threadedcavity 120 extends along anaxis 123 that is inclined relative to thelongitudinal axis 108. - In practice, when the
mounting bracket 102 is attached to the wall, theinclined axis 123 forms an angle with the vertical direction, so that the axis of the dowel extends downwards away from the wall. - The
movable member 105 is capable of pivotally oscillating about thelongitudinal axis 108 between a first position, in which thearm 103 extends horizontally relative to the wall, and a second position, in which thearm 103 is slightly inclined upwards relative to the horizontal direction. - Fully apparent from the above description is therefore the ability of the present invention to effectively reach the aims and advantages specified hereinbefore, by providing an arrangement enabling the position of the support arm to be adjusted in a simple, quick and effective manner.
- The inventive support arrangement enables the inclination of the
arm 103 relative to the mountingbracket 102 to be adjusted while theshelf 104 is partially mounted, i.e. with theshelf 104 that is just slightly moved away from the wall so that the second threadedmember 109 is capable of been reached with a tool for proper actuation. - In the case that the shelf is specially provided with an
appropriate bore 124, the possibility is given for the inclination of thearm 103 relative to the mountingbracket 102 to be adjusted while theshelf 104 is fully mounted, i.e. abutting tightly against the wall as shown in Figure 105. - The inclination of the second threaded
member 109 makes it particularly simple to perform the above-described adjustment operation, since it allows for convenient handling of the tool as suitably spaced apart from the wall. - With reference to the Figures 8-13, the concealed-type support arrangement for brackets, consoles, shelves, and the like according to a second embodiment of the present invention - as indicated generally at 201 in the Figures 8-13 - comprises a
longitudinal mounting bracket 202 adapted to be attached to a wall, atransverse support arm 203 capable of being inserted in a receptacle provided in ashelf 204, adjustment means for adjusting the position of thesupport arm 203 relative to the mountingbracket 202. - The shelf support arrangement further comprises a
movable member 205 accommodated in ahousing body 206 defined by the mountingbracket 202 and provided with a threaded bore 207 to rotatably engage a corresponding threadedportion 208 of thearm 203, coupling means 209 to block, i.e. firmly retain thearm 203 in thebracket 202 transversally relative thereto, a threadedmember 210 engaging saidmovable member 205 and adapted to cooperate with thehousing body 206 to longitudinally guide, i.e. translationally displace saidmovable member 205 within thehousing body 206 so as to adjust the longitudinal position of thearm 203 along thebracket 202, guide means 211 provided in saidhousing body 206 and adapted to cooperate with saidmovable member 205, via said threadedportion 208 thereof, saidarm 203 is adapted to cause saidmovable member 205 to slide transversally along said guide means 211 so that saidmovable member 205 rotates about a longitudinal axis C, thereby adjusting the inclination of thesupport arm 203 relative to the mountingbracket 202. - The mounting
bracket 202 is comprised of an elongated body that extends in a longitudinal direction A running parallel to the wall to which the mountingbracket 202 is due to be attached, wherein said elongated body is provided - at each end portion thereof - with a slot-like perforation 212 for thebracket 202 to be able to be secured to the wall by means ofappropriate screws 213. Such slot-like perforations 212 are so shaped as to enable the vertical position of thebracket 202 and, as a result, thesupport arm 203 to be adjusted relative to thescrews 213 fitted into the wall, so as to have the vertical position of theshelf 204 adjusted accordingly. - The mounting
bracket 202 forms integrally therewith, i.e. in a single-piece unitary construction with the same bracket, the above-indicatedhousing body 206, which defines a cavity adapted to accommodate themovable member 205. Thehousing body 206 protrudes from the attachment wall, and is adapted to be received in an appropriate receptacle provided within the thickness of the shelf, when the mountingbracket 202 is mounted in position against the wall. - On a front portion thereof, the mounting
bracket 202 is provided with a front slot-like aperture 214, through which access can be gained into the threaded bore 207 of themovable member 205 to let the threaded portion 8 of the support arm engage said bore. The slot-like aperture 214 is so shaped as to further enable thearm 203 to displace longitudinally and be inclined according to the related adjustment needs. Thearm 203, as associated to themovable member 205 and the mountingbracket 202, extends in a transversal direction B running perpendicular to the wall which thelongitudinal mounting bracket 202 is due to be attached to. - In an advantageous manner, the threaded bore 207 is a through-bore, so that an
end portion 215 of thearm 203 is capable of extending throughout themovable member 205 to eventually protrude therefrom so as to rotatably engage the coupling means 209. - The coupling means 209 comprise an abutting
member 216, which is constituted by a washer in the particular embodiment being discussed, and which is adapted to rotatably receive theend portion 215 of thearm 203 and position itself into abutment against the body of the mountingbracket 202 in correspondence to areceptacle 217 opposing the slot-like aperture 214. The coupling means 209 further comprise aninterference member 218, which is constituted by a kind of snap ring in the particular embodiment being discussed, and which is adapted to engage agroove 219 provided on theend portion 215 of thearm 203, as well as to come into contact with the abuttingmember 216 to prevent theend portion 215 of thearm 203 from sliding or displacing transversally relative to the abuttingmember 216 and, as a result, to retain thearm 203 transversally relative to the mountingbracket 202. - Advantageously, the abutting
member 216 is capable of sliding longitudinally along thereceptacle 217 provided in the mountingbracket 202 so as to allow thearm 203 to displace longitudinally along thesame bracket 202, whereas theinterference member 218, which is elastically deformable, allows theend portion 215 to be inclined relative to the abuttingmember 216 and, as a result, thearm 203 to be inclined relative to thebracket 202. - Of course, the coupling means 209 allow the
arm 203 to rotate about its own axis, so that the threadedportion 208 of thearm 203, when the latter is rotated, acts upon the threaded bore 207 to thereby drive themovable member 205 into displacing transversally, so as this will be described in greater detail further on. - The threaded
member 210 is linked to the interior of thehousing body 206 in a fixed longitudinal position, i.e. is retained longitudinally relative to thebracket 202, so as to be able to engage an internally threadedbush 220 of themovable member 205, and drive in this way themovable member 205 into moving, i.e. displacing longitudinally within thehousing body 206. - Anyway, the threaded
member 210 is free to slide transversally within thehousing body 206 and to rotate about its own axis jointly with themovable member 205. - The threaded
member 210 comprises ahead 221 that is secured longitudinally in a transversally extendingguide member 222 provided in thehousing body 206 and defined by a pair ofparallel edges 223 that retain such head longitudinally, while allowing it to both slide transversally along theguide member 222 and rotate on itself. - An
aperture 224, which is specially provided in the body of the mountingbracket 202 to such purpose, allows access to be gained to thehead 221 of the threadedmember 210 for it to be able to be actuated by means of a tool. Screwing the threadedmember 210 in and out causes themovable member 205 to slide, i.e. displace longitudinally within thehousing body 206 and, as a result, thearm 203 to displace longitudinally relative to the mountingbracket 202, owing to thearm 203 being firmly joined with themovable member 205. - The abutting
member 216, which is engaged by theend portion 215 of thesupport arm 203, is caused by thesame arm 203 to displace in the longitudinal direction A, so as to slide along thereceptacle 217 of the mountingbracket 202. - The
support arm 203 is firmly retained against the body of the mountingbracket 202 transversally by the coupling means 209, but is free to rotate about its own axis. Therefore, when thesupport arm 203 is rotated by a user to adjustment purposes, this will cause - owing to the screw-nut screw coupling existing between the threadedportion 208 of thearm 203 and the threaded bore 207 of the movable member 205 - themovable member 205 to displace in the transverse direction B. - The guide means 211 provided in the
housing body 206 are adapted to partially rotate themovable member 205 about the longitudinal axis C while themovable member 205 itself is displacing transversally, so as to cause thearm 203 to incline relative to the mountingbracket 202. - In the embodiment being described by way of illustrative example, the guide means 211 comprise at least one inclined plane or, more preferably, a pair of inclined planes provided in the
housing body 206 in proximity of the front slot-like aperture 214 of the mountingbracket 202. These inclined planes are adapted to cooperate with themovable member 205, and in particular with concavely contouredsurfaces 225 provided thereon, so that themovable member 205, when moving transversally towards the front slot-like aperture 214, is able to slide along the inclined planes so as to be rotated by as wide an angle as great the displacement of themovable member 205 is, thereby enabling thesupport arm 203 to be finely adjusted owing to the support arm itself being firmly associated to themovable member 205 to move jointly therewith. - The
movable member 205 is capable of sliding transversally within thehousing body 206 between a first extreme, i.e. end position, in which thesupport arm 203 extends horizontally from thebracket 202 when the latter is attached to the wall, and a second extreme, i.e. end position, in which thesupport arm 203 is inclined upwards by a greatest possible angle relative to thebracket 202. - Displacing the
movable member 205 transversally to any intermediate position therebetween will of course enable a corresponding different angle of inclination of thesupport arm 203 to be obtained relative to thebracket 202. - Fully apparent from the above description is therefore the ability of the present invention to effectively reach the aims and advantages specified hereinbefore, by providing an arrangement enabling the position of the support arm to be adjusted in a simple, quick and effective manner through the actuation of the threaded
member 210 and the corresponding rotation of thearm 203. - In a most advantageous manner, any adjustment of the position of the
support arm 203 can be performed without any need arising for the supported shelf to be completely removed from the support arm itself, since it is sufficient for the same shelf to be just slightly spaced apart, i.e. moved away from the mounting bracket for the threaded member to be able to be actuated and, as a result, the arm adjusted accordingly. - With reference to the Figures 14-20, the concealed-type support arrangement for brackets, consoles, shelves, and the like according to a third embodiment of the present invention - as indicated generally at 301 in the Figures 14-20 - comprises a
longitudinal mounting bracket 302 adapted to be attached to awall 303, atransverse support arm 304 capable of being inserted in a receptacle provided in ashelf 305, adjustment means for adjusting the position of thesupport arm 304 relative to the mountingbracket 302. - The shelf support arrangement further comprises a
movable member 306 accommodated in ahousing body 307 defined by the mountingbracket 302 and provided with a threadedbore 308 to rotatably engage a corresponding threadedportion 309 of thearm 304, coupling means 310 to block, i.e. firmly retain thearm 304 in thebracket 302 transversally relative thereto. - A first longitudinally extending
serration 311 is provided on saidmovable member 306 so as to be adapted to cooperate with a secondlongitudinally extending serration 312 provided inside saidhousing body 307 for the longitudinal position of themovable member 306 within thehousing body 307 and, as a result, thearm 304 along the mountingbracket 302 to be able to be adjusted. - Guide means 313 are provided in said
housing body 307 so as to be adapted to cooperate with saidmovable member 306; saidarm 304, through said threadedportion 309 thereof, is adapted to cause saidmovable member 306 to slide transversally along said guide means 313 so that saidmovable member 306 is rotated about a longitudinal axis C, thereby adjusting the inclination of thesupport arm 304 relative to the mountingbracket 302. - The mounting
bracket 302 is comprised of an elongated body that extends in a longitudinal direction A running parallel to thewall 303, which the mountingbracket 302 is due to be attached to, wherein said elongated body is provided - at each end portion thereof - with a slot-like perforation 314 for thebracket 302 to be able to be secured to thewall 303 by means ofappropriate screws 315. Such slot-like perforations 314 are so shaped as to enable the vertical position of thebracket 302 and, as a result, thesupport arm 304 to be adjusted relative to thescrews 315 fitted into the wall, so as to have the vertical position of theshelf 305 adjusted accordingly. - The mounting
bracket 302 forms integrally therewith, i.e. in a single-piece unitary construction with the same bracket, the above-indicatedhousing body 307, which defines internally acavity 316 adapted to accommodate themovable member 306. Thehousing body 307 protrudes from theattachment wall 303, and is adapted to be received in an appropriate receptacle provided within the thickness of theshelf 305, when the mountingbracket 302 is mounted in position against the wall. - On a front portion thereof, the mounting
bracket 302 is provided with a front slot-like aperture 317, through which access can be gained into the threaded bore 308 of themovable member 306 to let the threadedportion 309 of thesupport arm 304 engage said bore. The slot-like aperture 317 is so shaped as to further enable thearm 304 to displace longitudinally and be inclined according to the related adjustment needs. Thearm 304, as associated to themovable member 306 and the mountingbracket 302, extends in a transversal direction B running perpendicular to thewall 303, which thelongitudinal mounting bracket 302 is due to be attached to, as well as perpendicular to the axis A, along which the body of the mountingbracket 302 extends. - In an advantageous manner, the threaded
bore 308 is a through-bore, so that anend portion 318 of thearm 304 is capable of extending throughout themovable member 306 to eventually protrude therefrom so as to rotatably engage the coupling means 310. - The coupling means 310 comprise an abutting
member 319, which is constituted by a washer in the particular embodiment being discussed, and which is adapted to rotatably receive theend portion 318 of thearm 304 and position itself into abutment against the body of the mountingbracket 302 in correspondence to areceptacle 320 opposing the slot-like aperture 317. The coupling means 10 further comprise aninterference member 321, which is constituted by a kind of snap ring in the particular embodiment being discussed, and which is adapted to engage agroove 322 provided on theend portion 318 of thearm 304, as well as to come into contact with the abuttingmember 319 to prevent theend portion 318 of thearm 304 from sliding or displacing transversally, i.e. along the axis B, relative to the abuttingmember 319 and, as a result, to positively retain thearm 304 transversally relative to the mountingbracket 302. - Advantageously, the abutting
member 319 is capable of sliding longitudinally along thereceptacle 320 provided in the mountingbracket 302 so as to allow thearm 304 to displace longitudinally along thesame bracket 302, whereas theinterference member 321, which is elastically deformable, allows theend portion 318 to be inclined relative to the abuttingmember 319 and, as a result, thearm 304 to be inclined relative to thebracket 302. - Of course, the coupling means 310 allow the
arm 304 to rotate about its own axis, so that the threadedportion 309 of thearm 304, when the latter is rotated, acts upon the threaded bore 308 to thereby drive themovable member 306 into displacing transversally, so as this will be described in greater detail further on. - The
movable member 306 comprises afirst serration 311 that extends longitudinally along an upper portion of themovable member 306. Thisfirst serration 311 is substantially provided by correspondingly machining an upper surface of themovable member 306 so as to form a plurality of projecting teeth following each other in a regular sequence in a longitudinal direction running parallel to the axis A along which the body of the mountingbracket 302 extends, as this is clearly shown in Figures 14,15 and 19. - In turn, the
housing body 307 comprises asecond serration 312 provided on an inner surface of thesame housing body 307, wherein suchsecond serration 312 is provided so as to extend in correspondence to the first serration of themovable member 306, in a position lying substantially above saidfirst serration 311. Also thissecond serration 312 of thehousing body 307 is formed of a plurality of projecting teeth that follow each other in a regular sequence in a longitudinal direction along the axis A, i.e. the axis along which the body of the mountingbracket 302 extends. The teeth of the two above-citedserrations - The
movable member 306 is adapted to be moved, i.e. displaced longitudinally within thehousing body 307 to select a desired position of thearm 304 relative to the mountingbracket 302. Thefirst serration 311 on themovable member 306 is designed to slide along thesecond serration 312 on thehousing body 307 and be then stopped and retained in the selected longitudinal position by virtue of the torque generated by weight-force of thearm 304 and theshelf 305 mounted onsuch arm 304. In fact, the torque generated by the weight of thearm 304 causes the teeth of theserrations first serration 311 from slipping or sliding longitudinally on and relative to thesecond serration 312, and - as a result - immobilizing themovable member 306 within thehousing body 307 in the longitudinal position selected by the user. In practice, the user grasps thearm 304 and counterbalances the torque generated by the weight of thearm 304 so as to enable theserrations movable member 306 to slide longitudinally within thehousing body 307. Upon reaching the most suitable longitudinal position of themovable member 306 selected in view of enabling thearm 304 and, ultimately, theshelf 305 to be positioned in the correct manner as desired, the user then lets go of, i.e. releases thearm 304, the weight-force of which will therefore cause the teeth of theserrations movable member 306 longitudinally within thehousing body 307 and holding thearm 304 firmly in the selected position thereof. - The abutting
member 319, which is engaged by theend portion 318 of thesupport arm 304, is adapted to slide along thereceptacle 320 of the mountingbracket 302, as moved by thesame arm 304 to displace in the longitudinal direction A, when the position of thearm 304 is being adjusted by the user. - The
support arm 304 is firmly retained transversally against the body of the mountingbracket 302 by the coupling means 310, but is free to rotate about its own axis. Therefore, when thesupport arm 304 is rotated by a user to adjustment purposes, this - owing to the screw-nut screw coupling existing between the threadedportion 309 of thearm 304 and the threaded bore 308 of the movable member 306 - will cause themovable member 306 to displace in the transverse direction, i.e. along the axis B.
The guide means 313 provided in thehousing body 307 are adapted to partially rotate themovable member 306 about a longitudinal axis C while themovable member 306 itself is displacing transversally, so as to cause thearm 304 to incline relative to the mountingbracket 302. - In the embodiment being described by way of illustrative example, the guide means 313 comprise at least one inclined plane or, more preferably, a pair of inclined planes provided in the
housing body 307. These inclined planes are adapted to cooperate with themovable member 306, and in particular withside portions 323 thereof, so that themovable member 306, when moving transversally towards the front button-like aperture 317, is able to slide along the inclined planes, through theside portions 323, so as to be rotated by as wide an angle as great the displacement of themovable member 306 is, thereby enabling thesupport arm 304 to be finely adjusted into the desired position, owing to the support arm itself being firmly associated to themovable member 306 to move jointly therewith. - The teeth of the
serrations movable member 306 to concurrently move, i.e. slide transversally within thehousing body 307 and rotate about the axis C. - Advantageously, the
housing body 307 is provided laterally withapertures 324, through which theside portions 323 of themovable member 306 are received so as to allow for free movement of themovable member 306 transversally and related inclination of thearm 304. - The
movable member 306 is capable of sliding transversally within thehousing body 307 between a first extreme, i.e. end position, shown in Figure 17, in which thesupport arm 304 extends horizontally from thebracket 302 when the latter is attached to thewall 303, and a second extreme, i.e. end position, shown in Figure 18, in which thesupport arm 304 is inclined upwards by a greatest possible angle relative to thebracket 302. - Displacing the
movable member 306 transversally to any intermediate position therebetween will of course enable a corresponding different angle of inclination of thesupport arm 304 to be obtained relative to thebracket 302. - Therefore, adjusting the inclination of the
support arm 304 requires a user to simply rotate the arm in a given direction, relative to the axis B, to raise, i.e. incline thearm 304 upwards, and rotate thesame arm 304 in the opposite direction to bring thearm 304 back into the horizontal position thereof. For example, as indicated by the arrows shown on thehousing body 307 at the sides of the front slot-like aperture, rotating in the clockwise direction will enable the arm to be inclined upwards, while rotating in the counter-clockwise direction will cause the same arm to be moved back into the horizontal position thereof. - Fully apparent from the above description is therefore the ability of the present invention to effectively reach the aims and advantages specified hereinbefore, by providing an arrangement enabling the position of the support arm to be adjusted in a simple, quick and effective manner through the
serrations arm 304. - In a most advantageous manner, any adjustment of the position of the
support arm 304 can be performed without any need arising for the supported shelf to be completely removed from the support arm itself, since it is sufficient for the same shelf to be just slightly spaced apart, i.e. moved away from the mounting bracket for thearm 304 to be able to be actuated. - It shall be appreciated that the inventive support arrangement, as described above, is subject to a number of modifications and may be embodied in a number of different manners without departing from the scope of the present invention as defined in the appended claims. Furthermore, all related details, as described above, may of course be replaced with technically equivalent ones.
- It will finally be appreciated the materials used in connection with the present invention, as well as the sizing and the shapes of the various component parts, may each time be selected so as to more appropriately meet the particular requirements or suit the particular application.
