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.

A device (1) for facilitating the movement of pieces of furniture or the like, comprising an enclosure (2) which can be associated, by means of one of its sides, with the side of the piece of furniture to be directed toward the floor. The enclosure (2) defines internally a receptacle (3) for a resting element (4) which protrudes, in at least one active condition, from an opening (5) which is defined on the side of the enclosure (2) which lies opposite with respect to the side which can be associated with the piece of furniture. The resting element (4) can move with respect to the enclosure (2) from a movement position, in which it protrudes partially from the enclosure (2) through the opening (5) and constitutes an elastically yielding rest for the piece of furniture or the like on the floor, to a static position, in which it is at least partially retracted into the enclosure (2) with respect to the movement position for substantially rigid resting of the piece of furniture on the floor, and vice versa. The resting element (4) can move from the movement position to the static position in contrast with the action of elastic means (6) accommodated within the enclosure (2). The resting element (4) is crossed by at least one passage (7) for a tool for operating at least one connecting element (9), which is associated with the side of the enclosure which lies opposite the opening (5) and can engage the piece of furniture.
Description
- The present invention relates to a device for facilitating the movement of pieces of furniture or the like.
- As is known, moving pieces of furniture, particularly in the case of rather heavy items, is a tiring and awkward operation due to the friction and small differences in level which hinder the sliding of the piece of furniture on the floor.
- To make this operation easier, devices have been proposed, such as for example the device disclosed in
EP-402.346 - 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.
- In this manner, by unloading the piece of furniture it is possible to move it more easily, since it rests on the floor by means of the ball, whereas in normal conditions, when the piece of furniture is loaded, it rests firmly on the ground so as to avoid any accidental movement.
- These devices, in order to be able to apply them to the pieces of furniture, require the preliminary provision, in the foot or base of the piece of furniture, of a substantially cylindrical seat whose diameter is such as to accommodate coaxially the enclosure of the device substantially completely.
- This preliminary operation is not always accepted by potential users, particularly when the piece of furniture has a certain value, since it alters significantly the integrity of the piece of furniture, further weakening the foot or base of the piece of furniture and thus increasing the possibility of accidental breakages during use.
- 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.
- Within this aim, 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.
- This aim and these and other objects, which will become better apparent hereinafter, are achieved by 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 within said enclosure, said resting element being crossed by at least one passage for a tool for operating at least one connecting element, which is associated with the side of the enclosure which lies opposite said opening and can engage the piece of furniture.
