Definitions

  • the present invention relates to a device for facilitating the movement of pieces of furniture or the like.
  • devices such as for example the device disclosed in EP-402.346 , which are designed to be accommodated in a foot or more generally in the base of the piece of furniture and are provided with a ball which replaces the foot or base of the piece of furniture in resting on the floor during movement, so as to reduce the friction force that contrasts the movement and provide an elastically flexible contact which allows to negotiate small differences in level more easily.
  • Such devices generally comprise a substantially cylindrical enclosure, which is designed to be arranged inside a seat provided appropriately in the base or foot of the piece of furniture.
  • a cylindrical receptacle is provided in such enclosure for a ball which can protrude from an opening provided on the side of the enclosure which, when the device is assembled to the piece of furniture, is directed toward the floor.
  • Such ball can move axially along the cylindrical receptacle in order to pass from a movement position, in which it protrudes partially from the enclosure through such opening so as to replace the base of the piece of furniture in resting on the floor, to a static position, in which it is retracted into the enclosure, and vice versa. Retraction of the ball into the enclosure is contrasted by a spring which is accommodated within the enclosure.
  • the spring is sized so that when the piece of furniture is not loaded, i.e., when only the weight of the piece of furniture bears on the spring, the ball, under the action of the spring, protrudes below the piece of furniture, and when instead the piece of furniture is loaded with objects or people, the spring yields until the ball can retract substantially completely into the enclosure, thus allowing the piece of furniture to rest firmly on the floor.
  • the aim of the present invention is to solve the problem described above by providing a device which facilitates the movement of pieces of furniture or the like and does not require, for its application, significant alterations to the integrity of the piece of furniture or the like.
  • an object of the invention is to provide a device which can be applied to pieces of furniture or the like very simply and rapidly even by unspecialized personnel.
  • Another object of the invention is to provide a device which has high structural simplicity, so that it can be manufactured with greatly reduced costs with respect to known types of devices.
  • Another object of the invention is to provide a device which is composed of a small number of parts which are simple to manufacture and assemble.
  • Still another object of the invention is to provide a device which, notwithstanding its structural simplicity, is highly reliable in operation and has excellent durability.
  • a device for facilitating the movement of pieces of furniture or the like characterized in that it comprises an enclosure which can be associated, by means of one of its sides, with the side of the piece of furniture or the like to be directed toward the floor, said enclosure defining internally a receptacle for a resting element which protrudes, in at least one active condition, from an opening which is defined on the side of said enclosure which lies opposite with respect to the side which can be associated with the piece of furniture, said resting element being movable with respect to said enclosure from a movement position, in which it protrudes partially from said enclosure through said opening and constitutes an elastically yielding rest for the piece of furniture on the floor, to a static position, in which it is at least partially retracted into said enclosure with respect to said movement position for substantially rigid resting of the piece of furniture on the floor, and vice versa, said resting element being movable from said movement position to said static position in contrast with the action of elastic means accommodated
  • the device according to the invention generally designated in its two embodiments by the reference numerals 1, 1a, comprises an enclosure 2, 2a, which can be associated, by means of one of its sides, with the side of the piece of furniture, of which only a base or foot 3 0 to be directed toward the floor has been shown.
  • the enclosure 2, 2a defines internally a receptacle 3, 3a for a resting element 4, 4a which protrudes, in at least one active condition, from an opening 5, 5a which is defined on the side of the enclosure 2, 2a which lies opposite with respect to its side which can be associated with the piece of furniture.
  • the resting element 4, 4a can move, with respect to the enclosure 2, 2a, from a movement position, in which it protrudes partially from the enclosure 2, 2a through the opening 5, 5a and constitutes an elastically yielding rest for the piece of furniture on the floor, to a static position, in which it is partially retracted into the enclosure 2, 2a with respect to the movement position in order to produce substantially rigid resting of the piece of furniture on the floor, and vice versa.
  • the resting element 4, 4a can move from the movement position to the static position in contrast with the action of elastic means 6, 6a, 6b which are accommodated in the enclosure 2, 2a.
  • the resting element 4, 4a is crossed by at least one passage 7, 7a for a tool 8 for operating at least one connecting element 9, 9a which is associated with the side of the enclosure 2, 2a which lies opposite with respect to the opening 5, 5a and can engage the piece of furniture in order to fix the device to the piece of furniture.
  • the enclosure 2, 2a preferably is substantially cylindrical or frustum-shaped and tapers toward its end face designed to be fixed to the base or foot 30 of the piece of furniture, and can be associated, by means of an end face or upper end face 10, 10a thereof, with the base or foot 30 of the piece of furniture.
  • the receptacle 3, 3a preferably has a substantially cylindrical shape and is defined coaxially in the enclosure 2, 2a.
  • the opening 5, 5 a is defined at the other end face or lower end face of the enclosure 2, 2a, which lies opposite with respect to the upper end face 10,10a.
  • the resting element 4, 4a can slide axially in the receptacle 3, 3a and the elastic means 6, 6a, 6b comprise a spring which is interposed between the resting element 4, 4a and the upper end face 10, 10a of the enclosure 2, 2a.
  • the lower end face of the enclosure 2, 2a has an inner rim 12, 12a which surrounds the opening 5, 5a and defines a stop element, directed toward the inside of the receptacle 3, 3a, for a shoulder 13, 13a which is provided on the resting element 4, 4a in order to retain the resting element 4, 4a within the enclosure 2, 2a in contrast with the action applied by the elastic means 6, 6a, 6b.
  • the connecting element 9, 9a is constituted preferably by a self-tapping screw 14, 14a, which is accommodated with its head in the receptacle 3, 3a of the enclosure 2, 2a and passes, with its threaded stem, through a hole 15, 15a which is defined in the upper end face 10, 10a of the enclosure 2, 2a, preferably at the center of said upper end face 10, 10a.
  • the hole 15, 15a and the passage 7, 7a defined in the resting element 4, 4a are conveniently aligned one another so that the head of the screw 14, 14a faces the passage 7, 7a, as will become better apparent hereinafter.
  • the hole 15, 15a and the passage 7, 7a are aligned one another and are coaxial to the receptacle 3, 3a.
  • the resting element 4, 4a in the static position, is completely retracted into the enclosure 2, 2a so that the piece of furniture rests on the floor by means of the enclosure 2, 2a.
  • the elastic means 6, 6a are constituted preferably by a conical spiral spring 11, 11 a, which is connected, with its end located at the apex of the cone, to the head of the screw 14, 14a and rests, with its other end located at the base of the cone, against the side of the resting element 4, 4a that is directed toward the inside of the receptacle 3, 3a.
  • the spring 11, 11a is interposed between the head of the screw 14, 14a and a washer 16, 16a which rests against the side of the upper end face 10, 10a of the enclosure 2, 2a that is directed toward the inside of the receptacle 3, 3a.
  • the inner rim 12, 12a of the lower end face of the enclosure 2, 2a conveniently has discontinuities 17, 17a in order to facilitate the insertion of the resting element 4, 4a in the receptacle 3, 3a during the assembly of the device according to the invention.
  • the resting element 4 is substantially shaped like a dome 18, in which the top of the dome 18 is directed toward the opening 5 and is designed to rest on the floor.
  • the passage 7 is defined at the top of the dome 18.
  • the resting element 4 has a peripheral edge which protrudes laterally from the base of the dome and defines the shoulder 13, which faces the side of the inner rim 12 which is directed toward the inside of the receptacle 3.
  • the resting element 4a comprises a disk-like element 18a, which is arranged coaxially within the receptacle 3a and is covered, on its face directed toward the opening 5a, with a felt 19a or the like designed to rest on the floor.
  • the disk-like element 18a has a peripheral rim which defines the shoulder 13a which faces the side of the inner rim 12a which is directed toward the inside of the receptacle 3a.
  • the passage 7a passes through both the disk-like element 18a and the felt 19a or the like.
  • the device in the first embodiment is designed to be used on hard stone or ceramic floors, while the device in the second embodiment is designed to be used preferably on wooden floors, such as for example parquet flooring or the like.
  • the elastic means can be constituted by a Belleville washer 11b, made of polycarbonate or spring steel. It should be noted that although the Belleville washer 11b has been shown for the sake of simplicity only for the first embodiment of the device as a replacement of the spiral spring 11, it can also be adopted in the second embodiment of the device as a replacement of the spiral spring 11a.
  • the Belleville washer 11 b is crossed centrally by a hole, by means of which the washer 11b engages the head of the screw 14 or 14a and rests with its peripheral rim against the side of the resting element 4 or 4a that is directed toward the inside of the receptacle 3 or 3a.
  • the device according to the invention can be fixed very simply and quickly to the base or foot 30 of a piece of furniture by using the self-tapping screw 14, 14a.
  • a guiding hole of suitable diameter one proceeds by screwing the screw 14, 14a into such hole by means of a screwdriver or other similar tool 8 which is inserted in the enclosure 2, 2a through the passage 7, 7a provided in the resting element 4, 4a.
  • the device according to the invention is extremely simple to apply to the piece of furniture or the like and does not substantially alter the integrity of the piece of furniture, since it requires providing, in the piece of furniture, at most a guiding hole having a small diameter, which as such does not compromise the strength of the base or foot 30 of the piece of furniture.
  • the spring 11, 11 a, 11b keeps the resting element 4, 4a in the movement position, i.e., so that it protrudes partially from the lower end face of the enclosure 2, 2a, as shown in Figures 5 , 11 and 14 .
  • the piece of furniture rests on the floor by means of the resting element 4, 4a, which ensures limited friction on the floor and provides elastically yielding resting, facilitating the negotiation of slight differences in level and making it considerably easier to move the piece of furniture along the floor.
  • the spring 11, 11 a, 11b is compressed by this weight, and the resting element 4, 4a passes to the static position, i.e., it retracts into the enclosure 2, 2a, as shown in Figures 6 , 12 and 15 .
  • the piece of furniture rests on the floor by means of the enclosure 2, 2a and therefore stable resting of the piece of furniture is achieved, avoiding its accidental movement.
  • the device according to the invention fully achieves the intended aim, since it is extremely simple to apply to pieces of furniture without substantially altering the integrity of the piece of furniture or the like.
  • the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
