Magnetic fixing unit

A locking magnetic fastener comprising:

• a first housing assembly having a front face, an outer surface extending from the front face, a passage, and a channel opening on the outer surface;
• a slide member arranged with a manual actuation portion extending through and movable in said channel, having at least a portion made of a material attracted by a magnetic force, and having an abutment stop;
• a second housing assembly having a projection, said projection being shaped to fit within said passage and having an abutment surface, and
• a magnet arranged within the first housing or the second housing,
• wherein said magnet, said projection, said slide member, said passage, and said channel are arranged such that when said projection is inserted into said passage a magnetic force urges said slide member in a first direction within said channel such that said abutment stop extends into said passage and said abutment surface and said abutment stop prevent said projection from being withdrawn from said passage, and when a manual force is applied to said manual actuation portion in a direction opposite said first direction said slide member moves said abutment stop out of said passage away from said projection thereby releasing said projection, and
• wherein the magnet includes an opening to receive the projection.

A locking magnetic fastener comprising:

• a first housing assembly having a front face, a back face, a receptacle extending from an opening on said front face toward said back face, and an outer surface extending from said front face to said back face, said first housing assembly having a channel opening on said outer surface and said receptacle having a passage opening;
• a slide member arranged with a manual actuation portion extending through and movable in said channel, having at least a portion made of a material attracted by a magnetic force, and having an abutment stop;
• and
• a second housing assembly having a projection, said projection being shaped to fit within said receptacle and having an abutment surface, and
• a magnet arranged within the first housing or the second housing;
• wherein said magnet, said projection, said abutment surface, said channel, said passage, and said slide member are arranged such that when said projection is inserted into said receptacle a magnetic force from said magnet urges said slide member in a first direction within said channel such that said abutment stop extends into said passage and said abutment surface and said abutment stop prevent said projection from being withdrawn from said receptacle, and when a manual force is applied to said manual actuation portion in a direction opposite said first direction said slide member moves said abutment stop out of said passage away from said projection thereby releasing said projection from said receptacle.

A locking magnetic fastener comprising:

• a first assembly including a projecting member;
• a second assembly including (i) a slidable engaging member, and (ii) a guide member configured to accommodate the projecting member and to extend in a first direction from an opening on a front face of the second assembly toward a back face of the second assembly;
• and
• a magnet,
• wherein the first assembly includes the magnet,
• wherein the guide member provides, in part or in whole, a passage extending substantially perpendicular to the first direction,
• wherein the first assembly and the second assembly are configured such that (i) the magnet attracts the first assembly towards the second assembly to insert the projecting member into the second assembly and (ii) the slidable engaging member of the second assembly can slide, through the passage, to engage the projecting member of the first assembly to releasably lock the first assembly to the second assembly, and
• wherein the projecting member of the first assembly includes a head and a stem that do not contain the magnet.
