The present invention relates to a glide assembly system to connect adjacent furniture legs on items such as, for example, chairs or tables. For example, chairs can have a glide assembly attached at the bottom of each of its front legs or to all of its legs, or a table can have a glide attached to some or all of its legs. Each glide may have a magnet that, when mated with adjacent glide's magnet, connects the chair legs and/or table legs together, without requiring tools or mechanical fasteners to connect or disconnect. The magnets used to connect the chairs and tables together allows one to easily attach or detach chairs and/or tables. Use of male/female glide assemblies increases the resistance to accidental disconnection.
In many environments, it is desirable to have a row or rows of chairs where the chairs appear more presentable if the rows are aligned. The situation can be the same for tables, or other furniture items. For example, one may want several tables aligned end to end, or side by side. Also, one may want multiple tables aligned both end to end and side by side, for example 6 tables aligned 3 tables long and 2 tables wide to create a larger meeting or display table.
While chairs or tables or other furniture items can be set-up so that they are aligned as desired, if they are not connected in some way, they are easy to become misaligned. The ability to easily connect and disconnect the furniture items is also preferable, as disconnecting allows for easier storage of the furniture items.
Over the years, various mechanical connectors have been used to connect chairs together, either permanently or temporarily. Examples include bent arms and cavities, where the arms are connected into the cavities to connect chairs; a keyway on one side of a chair and an engaging key on a side of an adjacent chair; legged chairs with upstanding posts having an unlegged chair between a pair of legged chairs where the unlegged chair has sockets that fit onto the upper end of the upstanding posts of the adjacent legged chairs; and chairs with a pair of spaced apart N-S magnets along a chair seat which can mate with a pair of spaced apart S-N magnets along the seat of another chair.
A glide assembly system to connect adjacent furniture legs involves male and female glide assemblies which are insertable into the legs of furniture. A male glide assembly inserted into the leg of a piece of furniture which abuts a female glide assembly inserted into the leg of an adjacent piece of furniture is used to connect the legs of the furniture together until the furniture is pulled apart to separate.
The glide assemblies preferably have a body with a curved bottom surface which make it easier to slide the furniture along a floor surface. A male glide assembly has a magnetic assembly extending from a receptacle and a female glide assembly has a magnetic assembly received internal to a receptacle. The metal cup of the magnetic assembly in the male glide assembly is inserted into the receptacle in the female glide assembly to engage the metal cup of the magnetic assembly in the female glide assembly. In some embodiments, two magnets of opposed polarity are used in the magnetic assemblies of the male and female glide assemblies. It is noted that non-polarized magnets provide connectivity, but it is preferable to use polarized N-S magnets thereby enhancing the strength of the connection. In other embodiments, a magnet may be used in one of the glide assemblies and a member magnetically attracted to the magnet may be used in the other glide assembly. Male/female glide assembly conjunction with magnets increases the resistance to accidental disconnection by providing added resistance when vertical and horizontal forces are applied to the conjunction.
The male and female glide assemblies each have a body which may be of unitary or non-unitary construction. In some embodiments, the body is injection molded.
More specifically, the present invention is for a glide assembly system to connect adjacent furniture legs, including a) a male glide assembly having a body, the body having a curved bottom portion, the body having an upward extending leg insertion portion and a receptacle extending transverse to the leg insertion portion, the receptacle having a receptacle depth from its interior outward; a magnet assembly having a metal cup having an exterior cup depth and an interior cup depth, the metal cup having a bottom and a wall portion, the wall portion having a non-metallic spacer on its interior wall portion, the metal cup receiving a magnet therein, the magnet attached to the bottom of the metal cup and abutting the non-metallic spacer, the magnet having a magnetic depth, the magnetic depth being less that the interior cup depth of the metal cup, the magnet assembly received into the receptacle of the male glide assembly, the receptacle depth being less than the exterior cup depth of the metal cup; b) a female glide assembly having a body, the body having a curved bottom portion, the body having an upward extending leg insertion portion and a receptacle extending transverse to the leg insertion portion, the receptacle having a receptacle depth from its interior outward; a magnet assembly having a metal cup having an exterior cup depth and an interior cup depth, the metal cup having a bottom and a wall portion, the wall portion having a non-metallic spacer on its interior wall portion, the metal cup receiving a magnet therein, the magnet attached to the bottom of the metal cup and abutting the non-metallic spacer, the magnet having a magnetic depth, the magnetic depth being less that the interior cup depth of the metal cup, the magnet assembly received into the receptacle of the female glide assembly, the receptacle depth being more than the exterior cup depth of the metal cup; and c) where the metal cup of the male glide assembly can engage the metal cup of the female glide assembly and prevent the male and female glide assembly magnets from touching, and also prevent the male and female glide assembly receptacles from touching.
In this situation, male and female glide assembly magnets may have an opposite polarity to each other, although non-polarized magnets may be used. The body of each glide member may be unitary or non-unitary. In the unitary body, magnet assemblies of the male and female glide assemblies each have a central countersunk opening therethrough, the receptacles of the male and female glide assemblies each have a central pilot hole extending into the body, a fastener received through each central countersunk opening of the magnet assemblies and received into the pilot hole of the bodies. A preferred fastener is a screw which is threaded into the pilot hole. Other possible fasteners include bolts and rivets.
In the non-unitary body, the receptacles of the male and female glide assemblies each have a central opening extending through the body to the side opposite each receptacle, each central opening having a key slot extending inward from the body side opposite each receptacle, where an adapter is inserted into the central opening from the body side opposite each receptacle of the male and female glide assemblies, each adapter having a head and a shaft, the shaft having a key thereon, the key extending outward from the shaft adjacent the adapter head, the shaft having a central pilot hole extending inward from the shaft end opposite the head toward the receptacle, where the key slot and key engage each other. Even further, the magnet assemblies of the male and female glide assemblies each have a central countersunk opening therethrough, with a fastener received through each central countersunk opening of the magnet assemblies and received into the central pilot hole of the shaft.
To utilize the glide assembly system to connect chairs together, a male glide assembly is received into the right front leg of a first chair and a female glide assembly is received into the left front leg of the first chair, a male glide assembly is received into the right front leg of a second chair and a female glide assembly is received into the left front leg of the second chair, the first and second chairs being connectable by having the metal cup in one of the male glide assemblies engage the metal cup in one of the female glide assemblies.
As an alternative to using a magnet assembly in both of the male and female glide assemblies, one of the magnet assemblies can be replaced with a member which is magnetically attracted to the magnet assembly of the other glide assembly, the member having a member depth, the member received into the receptacle of the glide assembly. For a female glide assembly, the receptacle depth will be more than the member depth. If used with a male glide assembly, the receptacle depth will be less than the member depth. The metal cup of the glide assembly with the magnet assembly can engage the member of the other glide assembly and prevent the magnet in the glide assembly with the magnet assembly from touching the member in the other glide assembly, and also prevent the two glide assembly receptacles from touching.

Glide assemblies 10 and 30 are preferably injection molded using a glass filled nylon material, although other materials and manufacturing techniques may also be used. The bodies 12 and 32 of glide assemblies 10 and 30 each have a curved bottom 13 and a leg insertion portion 14 extending upward. Male glide assembly 10 has a receptacle 16 and female glide assembly 30 has a receptacle 36 each extending transverse to the upward leg insertion portion 14. Each receptacle 16/36 has a receptacle depth from its interior outward. The receptacle depth of the male glide assembly is less than the receptacle depth of the female glide assembly.
A magnet assembly preferably used with each glide assembly has a metal cup 17, preferably of a steel material, which has an exterior cup depth and an interior cup depth. Each metal cup 17 has a bottom and a wall portion, the wall portion having a non-metallic spacer 19 on its interior portion. Spacer 19 is preferably of a nylon or plastic material. Metal cup 17 used with the male glide assembly 10 receptacle 16 receives a magnet 18 therein and metal cup 17 used with the female glide assembly 30 receptacle 36 receives a magnet 38 therein. Magnets 18 and 38 are preferably made of neodymium, but can be made of other magnetic material. Magnets 18 and 38 are attached to the bottom of their respective metal cups 17 and abut the non-metallic spacer 19 inside each cup 17. Magnets 18 and 38 have a magnet depth which is less than the interior cup depth of the respective metal cup 17.
Magnets 18 and 38 should have opposing polarity to each other. While polarity could be flipped, as shown, magnet 18 has north polarity exposed and magnet 38 has south polarity exposed. With magnet 18 inserted into cup 17 and attaching to the cup bottom and not touching the cup sides due to spacer 19, the exposed outer edge of the metal cup 17 will also be of north polarity. Likewise, for magnet 38, the exposed outer edge of the metal cup 17 will be of south polarity.
The magnet assemblies with magnets 18 and 38 are received into the receptacle 16 of the male glide assembly 10 and the receptacle 36 of the female glide assembly 30. For the male glide assembly 10, the receptacle 16 depth is less than the exterior cup depth of the associated metal cup 17. In contrast, for the female glide assembly 30, the receptacle 36 depth is more than the exterior cup depth of the associated metal cup 17. With these dimensional relationships, when the male glide assembly 10's exposed north polarized outer edge of metal cup 17 connects to the female glide assembly 30's exposed south polarized outer edge of metal cup 17, magnets 18 and 38 can not touch. Also, the outer edges of the male and female glide assemblies 10 and 30 can not touch.
