Definitions

  • This invention relates to furniture joint, especially for upholstered furniture, for blocking movable position of an element of a piece of furniture in any position.
  • the invention is used especially for regulating position of headrests, arm-rests, leg-rests and back in chairs, armchairs, sofas, beds.
  • the invention may also be used in other types of furniture, for example for flaps and doors of kitchen cupboards and bathroom cases.
  • the known joint enables blocking of a movable element of a piece of furniture in at least several settled positions by stepwise lifting and lowering of that element. After taking proper position by a movable element its bloking takes place by operations of the pawl.
  • the angle of position of a movable element of a piece of furniture, detenning number of positions, in which blocking takes place, is a result of a pitch of the pawl.
  • Stepwise change of position of a movable element of a piece of furniture and its bloking in this position make inconvenience in usage of the known furniture joint.
  • a furniture joint which construction enables blocking of position of a movable element of a piece of furniture in any position during fluent lifting and lowering of movable element of a piece of furniture.
  • Furniture joint especially for upholstered futniture, according to the invention, having a stable aim fixed to a stable element of furniture and a movable arm joined with a movable element of furniture, moreover the movable arm is fixed rotationally towards the stable arm , characterised in that , to one of the arms, advantegously to the movable ann, one-way grip is mounted immovably towards this arm , moreover one-way grip is seated on the circuit of a disk, and the disk is placed immovably towards frictional inserts and it is seated on their hubs.
  • One-way grip has a hole and a through groove which divides up the grip into two parts, moreover each of the parts is joined with an arm, advantageously with the movable arm.
  • one-way grip contains a stop of extention of the grip, moreover the stop is a resistance element for a part of the grip and the stop is situated within the limits of the parts of the grip.
  • Frictional inserts are situated towards themselves in such a way, that they are directed to each other with their hubs.
  • One-way grip, the disk, and frictional inserts are placed between endings of an ann, advantageously of a stable arm and they are joined with one another by means of a screw, moreover between the screw and outer surfaces of endings of the arm, advantageously of the stable arm, pressure springs are placed, advantageously disk springs with regulated degree of compression, moveover degree of compression of pressure springs is regulated by means of the screw.
  • One-way grip contains blocking elements which, in extreme positions of the movable ann contact with a resistance element.
  • Construction of a furniture joint enables locking of position of a movable element of a piece of furniture in any position suitable for a user.
  • There is not indirect angle limit of position of a movable element as lifting and lowering of that element come fluently.
  • In the joint according to the invention there is a possibility of regulation of resisting force of friction connected with work of the joint, which is essential from the point of view of particular users. Setting of this force, that is resistance of friction, takes place ealier, before usage of a piece of furniture with this joint. Regulation of the force is simple, as it relies on pressing down arms with a suitable force as a result of work of a screw.
  • fig. 1 presents a joint in section A-A, fig.2 - a joint from above, fig.3 - a joint in perspective view, fig .4 - a joint in side view, fig.5 - a flat bar of a stable arm from above, fig.6 - a flat bar of a stable arm in side view, fig.7 - a flat bar of a movable arm from above, fig.8 - a flat bar of a movable arm in side view, fig.9 - a grip from above, fig.10 - a disk from above, fig.11 - a disk in side view, fig.12 - a frictional insert from the side of a hub, fig.13 - a frictional insert in section C-C, fig.14 - a joint with an arm blocked in one extreme position, fig.15 - a joint with an ann blocked in second extreme position
  • a furniture joint, especially for upholstered furniture, according to the invention is constructed from a stable element 1 fixed to a stable element of a piece of furniture and a movable arm 2 fixed to a movable element of a piece of furniture, for example to a head-rest, or to an ann-rest.
  • the movable ann 2 is fixed rotationally towards the stable arm 1 .
  • one-way grip 6 is mounted in two points by means of rivets 3 .
  • the grip 6 is a flat element, having an hole 8 and a through groove 10 .
  • the groove 10 divides up the grip 6 into two parts 6a , 6b , moreover each of the parts 6a , 6b is joined with an arm, advantageously with the movable arm 2 by means of the rivet 3 .
  • one-way grip 6 contains a stop 15 of extention of the grip 6 , moreover the stop 15 is a resistance element for a part 6a of the grip 6 and the stop 15 is situated within the limits of the parts 6a , 6b of the grip 6 .
  • the grip 6 is seated with its hole 8 on the circuit of the disk 9 .
  • the disk 9 is placed immovably towards frictional inserts 4 and it is seated on their hubs 12 .
  • Connection of the disk 9 with frictional inserts 4 may be a splined joint or polygonal, for example hexagonal or it may be realized by means of a key.
  • Frictional inserts 4 are situated towards themselves in such a way, that they are directed to each other with their hubs 12 .
  • the grip 6 , the disk 9 , and frictional inserts 4 are placed between endings 13 of an arm, advantageously of a stable arm 1 and they are joined with one another by means of a screw 5 .
  • pressure springs 7 are placed, advantageously disk springs with regulated degree of compression. Degree of compression of pressure springs 7 is regulated by means of the screw 5 .
  • Blocking elements 11a , 11b of the grip 6 block extreme positions of the movable arm 2 as a result of contact with a resistance element 14 mounted in the stable arm 1 .
  • the stable arm 1 is made of two, adjoined to each other flat bars 16 joined with each other.
  • the movable arm 2 has a shape of a straight element and it is made of two, adjoined to each other flat bars 17 joined with each other.
  • the stop 15 of extention of the grip 6 starts to transfer force in the moment when blocking element 11a meets resistance as a result of contact with a resistance element 14 , what takes place during turn of the movable arm 2 to extreme position. It prevents exessive bend of a part 6a of the grip 6 and this way it prevents a joint from damage.
  • Blocking elements 11a , 11b state the range of work of a joint and they may be situated depending on user' needs.
