  • ABSTRACT 0 Foreign Application Priority Data
  • the lockset includes two cy- 70/152; 292/ 170; 292/DIG, 72 lindrical elements, which are engaged head to head [51] Int. Cl.
  • General objects of the invention are to minimize the visibility of such a lock, to do away with the pull, and to provide a slight thrust to the part that is released upon disengagement of the bolt, allowing the user to grasp the edge of the disengaged part and pull it open fully.
  • the panels employed are suitably bevelled on their inside faces, which results in an improved joining of the panels as well as in an improved handling of the opening panel.
  • a combined opening and closing device is obtained.
  • This particular feature combined with the shape of the panels employed, makes it possible to eliminate the pull; consequently the whole' piece of furniture displays a more functional design.
  • a cylinder type springlock is employed, embedded lengthwise in the opening panel. This lock acts upon a cylinder arranged normal to it and also embedded in the locking normal panel. The latching point lies on the diagonal, coinciding with the bisector plane of the dihedral angle formed by the panels.
  • the second cylinder placed normal to the latchbolt. is loaded with a spring powered plunger constantly under tension and pressing upon a certain spot of the first cylinder; consequently, upon withdrawal of the latchbolt, the first cylinder is thrust forward, which results in a partial opening of the engaged panel, in which the first cylinder is embedded.
  • the first cylinder equipped with an axial latchbolt
  • the pushbutton activates the withdrawal of the latchbolt, and, consequently, the opening of the panel, by applying a perpendicular stress on an inclined plane located on the surface of the bolt.
  • the latchbolt can be conveniently blocked in a locked position by means of a cam operated shaft, which is positioned at the base of the first cylinder in such a way as to prevent the withdrawal of the latchbolt.
  • the lock can be embedded as well as anchored into or fastened to the face of the panel in any suitable fashion.
  • FIG. 1 shows a sectional view of the lockset mechanism embedded in two panels; the lock is also provided with key operated latchbolt blocking mechanism; and
  • FIG. 2 shows a sectional view of the lockset mechanism with one part fastened to but not embedded in a glass panel.
  • FIG. 1 A preferred embodiment of the recessed lockset mechanism of this invention is shown in FIG. 1.
  • a first furniture panel 2 has anedge surface 2a bevelled at an angle of about 45.
  • a second furniture panel 4 has a complementary bevelled edge surface 4a.
  • the panels 2 and 4 are movable relative to each other; for example, panel 2 may be hinged at one side (not shown) to form a door of a cabinet.
  • a suitable hinge mechanism is, in fact, disclosed and claimed in my copending application Ser. No. 480,276, filed June 12, 1974.
  • a cylindrical hole is drilled into the furniture panel 2 from its bevelled surface 2a and a metal cylinder case 6 may be press-fitted and/or glued in the hole to secure it to the furniture panel; the face portion of the casing 5 is bevelled so that when inserted, the face of the casing is flush with the surface 2a.
  • the cylinder 6 has an end plate 8 with a central opening 10.
  • a movable elongated cylindrical shaft 12 is located in the housing 6.
  • a spring 14 is mounted coaxially with shaft 12; one end of spring 14 abuts the end plate 8 and the other end contacts one end of the enlarged central portion 12a of the shaft 12.
  • the central portion 12a of the shaft 12 has a notched surface 16 which cooperates with a pushbutton 18 located in an opening 20 in the furniture panel 2.
  • the pushbutton protrudes outwardly from the furniture panel to permit actuation by the user.
  • the inner end of the button cooperates with the notched portion 16 so that when the button is pushed in the direction of arrow B, it acts to push the shaft backward (in a direction opposite to that of arrow A) against the biasing force of spring 14.
  • the spring 14 returns the shaft 12 forwardly in the direction of arrow A thus urging the button outwardly in a direction opposite to that of arrow B. Movement of the button in this direction is limited by the enlarged diameter ridge 18a of the button engaging a reduced diameter portion 20a of the button opening 20.
  • the lockset mechanism may also be provided with a lock, such as a key operated lock 24 having a keyhole located at 24a.
  • a lock such as a key operated lock 24 having a keyhole located at 24a.
  • Eccentrically mounted on the rotatable shaft of lock 24 is a cam member 26.
  • the cam 26 engages the end of shaft 12 protruding through opening 10 in end plate 8. This prevents movement of the shaft 12 in an opening direction (opposite to arrow A) when button 18 is actuated by being pushed in the direction of arrow B.
  • cam 26 In the unlocking position, cam 26 is moved out of contact with the end of shaft 12 (as shown in dotted line configuration in FIG. 1) to permit the pushbutton 18 to move shaft 12 backward.
  • Furniture panel 4 also has an opening drilled therein from bevelled face 4a into which a cylindrical metal casing 28 is fitted, by press-fitting, gluing, etc.
  • the face of cylindrical casing 28 is also bevelled in conformance with the bevelling on face 4a.
  • the casings 6 and 28 are located opposite each other so that their respective longitudinal axes intersect each other at approximately right angles.
  • the casing 28 has an opening or recess 30 formed therein.
  • a springloaded shaft or plunger 32 Movably mounted in casing 28 is a springloaded shaft or plunger 32, normally biased in the direction of arrow C by means of a spring 34 mounted between the rear face of shaft 32 and the inner end face of casing 28.
  • the front end face 32a of shaft 32 (which may be made of a rubber or plastic material) abuts against an extension 6b of casing 6.
  • plunger 32 pressing against extension 6b, provides sufficient thrust to push panel 2 away from panel 4 to an open position.
  • the furniture panel 2 is replaced by a glass plate or panel 36.
  • the cylindrical casing 6 is mounted to the glass plate by means of a mounting block 38 which is secured to the inside of the glass by glue or any other known means.
  • the block 38 has an opening 40 with a diameter corresponding to the outside diameter of casing 6.
  • the casing is secured to the block 38 by a set screw 42, for example.
  • this embodiment is substantially the same as that described above with respect to FIG. 1.
  • Locking apparatus for furniture articles and the like comprising: a first elongated member; first means mounting said first member to a first furniture panel for movement along the longitudinal axis of said firstmember; a second elongated member; second means mounting said second member to a second furniture panel for movement along the longitudinal axis of said second member; first biasing means urging said first member into locking engagement with said second mounting means for locking said first and second furniture panels against relative movement; second biasing means urging said second member into engagement with said first mounting means; and means coupled to said first member for moving said first member in a direction 0pposite to its normally biased direction and out of locking engagement with said second mounting means to permit relative movement of said first and second furniture panels.
  • said first mounting means comprises a first hollow cylinder in which said first elongated member is movably mounted; said first biasing means comprises a first spring located in said first hollow cylinder and engaging said first member and a wall of said first hollow cylinder; said second mounting means comprises a second hollow cylinder in which said second elongated member is movably mounted; and said second biasing means comprises a second spring located in said second hollow cylinder and engaging said second member and a wall of said second hollow cylinder.
  • Locking apparatus wherein said first elongated member comprises a shaft having a notched central portion; and said means coupled to said first elongated member for moving said first member comprises a pushbutton mounted to said first furniture panel for engagement with said notched central portion.
  • Locking apparatus further comprising: locking means movable between locking and unlocking positions, wherein in said locking position, said locking means engages said first member to prevent movement thereof out of locking engagement with said second mounting means and in said unlocking position said locking means is disengaged from said first member to permit movement of the latter out of locking engagement with said second mounting member.
  • Locking apparatus wherein said locking means comprises a cam eccentrically mountedon a rotatable shaft, said cam engaging one end of said first member in said locking position and being disengaged from said first member in said unlocking position.
