Definitions

  • This invention relates to a latch holding apparatus of a handle for opening and closing a door, in which the handle is placed in a locked state by holding a latch in a locked position. More particularly, the invention relates to a latch holding apparatus used in a double-leafed hinged door attached to the rear or side of, e.g., a van-type vehicle, and adapted in such a manner that when a handle to be locked is placed in a locked state or unlocked state, the latch can be held reliably in a locked position or unlocked position, respectively.
  • numeral 1 denotes a double-leafed hinged door attached to an opening at the rear or side of a van-type vehicle V or sea-borne container.
  • the double-leafed hinged door 1 is mounted by hinges 2 on a side column 3 of the opening.
  • Numeral 4 denotes a locking rod constituting a lock device.
  • the rod 4 has cams 5 at its upper and lower ends and is mounted on the main body of the door 1 so as to be capable of turning.
  • a handle 6 for turning the locking rod 4 about its axis is provided on the rod 4 as a integral part thereof.
  • Numeral 7 denotes a cam keeper provided on upper and lower frame members of the opening.
  • Numeral 8 denotes a latch apparatus for retaining the handle 6, which turns in unison with the locking rod 4, in a horizontal attitude, and for locking the handle 6 at the time of a closing operation.
  • Fig. 13 which is a perspective view of the portion indicated by the arrow XXIV in Fig. 12, shows the details of the latch apparatus and handle 6.
  • the handle 6 is engaged with and supported by a bracket 9 fixedly secured to the double-leafed hinged door.
  • a door lock latch 10 capable of being turned up and down has a simple structure in which the latch 10 is engaged with the handle 6 from above to prevent the handle 6 from separating from the bracket 9.
  • Numeral 11 denotes concentric holes provided in the bracket 9 and latch 10. Locking is achieved by inserting the shank of a padlock 12 through the holes 11. The handle cannot be turned unless the padlock 12 is opened.
  • the conventional latch apparatus 8 thus constructed involves a troublesome opening and closing operation since the latch is held by the padlock 12. Specifically, in terms of the operation performed at unlocking,
  • numeral 71 denotes a biased body moved between the position of a pin a and the position of a pin b.
  • the biased body is a latch member for locking the handle of a van-type vehicle, by way of example.
  • the biased body 71 turns about a pivot shaft 72 to be changed over between the position of pin a and the position of pin b.
  • Numeral 73 denotes a coil spring having one end engaged with a pin 74 provided on an end of the biased body 71, and another end engaged with a fixed pin 75 separate from the biased body 71.
  • a force is applied in the direction of arrow A in order to change over the biased body 71 from the position of pin a in Fig. 14(a) to the position of pin b in Fig.14 (b).
  • the coil spring 73a stretches to a point beyond a straight line X-X' passing through the pivot shaft 72, namely a point beyond a neutral position. Therefore, the biased body is turned against the spring force, though when the straight line X-X' is surpassed, the biased body is turned automatically to the position b, where it comes to rest.
  • Figs. 15(a), (b) shows another example of the biasing device.
  • a leaf spring 73b is used as the spring which applies the spring force to the biased body 71. If the biased body 71 is pushed against a maximum repulsive force, produced when it passes over a central projection 76b of the leaf spring 73b, at such time that the biased body 71 is moved from the a position to the b position, the biased body 71 will turn automatically and be held at the b position.
  • Figs. 16(a) (b) also show another example of the biasing device.
  • the arrangement used is one in which one end of a torsion coil spring 73c is engaged with a pin 77 provided on the lower portion of the biased body 71. Operation is the same as in the foregoing two examples, with the biased body being held at the a and b positions by the coil spring 73c.
  • Figs. 17(a) (b) show yet another example of the biasing device.
  • a spring seating member 80 is attached to the lower portion of the biased body 71 via a pin 78, and a spring seating member 81 is attached via a pin 79 to a fixed position separate from the biased body 71.
  • a coil spring 73d is attached between the two spring seating members 80, 81. Accordingly, when the biased body is in line with the neutral line X-X', the coil spring 73 is compressed to the maximum extent, whereby the maximum spring force is generated. When this neutral position is exceeded, the biased body is turned automatically toward the b position or the a position, where it comes to rest.
  • the width l3 of the leaf spring 73b is large.
  • the length and width of the coil spring 73c are of considerable size.
  • Co-pending European application EP-A-0408169 provides a prior art according to article 54(3) EPC and describes a latch holding apparatus of a handle for opening and closing a door, in which a latch pivotally secured to a base fixed to a door main body is held in a locked position, whereby the handle is placed in a locked state, comprising: a pair of handle grips in each of which a recess is formed for insertion of the handle; a pivot shaft for turnably supporting the latch on said handle grips; and holding means for holding the latch in the locked position when the handle is inserted into said handle grips and for holding the latch in an unlocked position when the handle is separated from said handle grips.
  • the present invention provides a latch holding apparatus of a handle for opening and closing a door used very frequently, in which a latch member can be held in its locked and unlocked positions reliably and the handle can be locked and unlocked by a single touch.
  • the present invention also provides a safely operable latch holding apparatus of a handle for opening and closing a door, in which the apparatus can be attached at a hidden position of a latch device or the like for locking the handle, and in which the positioning of a held latch can be performed in reliable fashion.
  • a latch holding apparatus of a handle for opening and closing a door in which a latch pivotally secured to a base fixed to a door main body is held in a locked position, whereby the handle is placed in a locked state
  • the apparatus comprising: a pair of handle grips in each of which a recess is formed for insertion of the handle; a pivot shaft for turnably supporting the latch on said handle grips; and holding manes for holding the latch in the locked position when the handle is inserted into said handle grips, and for holding the latch in an unlocked position when the handle is separated from said handle grips, and wherein when the holding means comprises biasing means provided between pins in the latch and the base respectively, the pins have axes which are substantially coincident when the latch is held in its locked and its unlocked position.
  • the latch holding apparatus of a handle for opening and closing a door in the present invention is such that the latch member is pivotally secured to the base and is capable of being held in its open and closed positions by a simply constructed holding device.
  • the invention therefore is very effective when utilized in a collection and delivery vehicle for parcels and the like, in which a door is opened and closed very frequently.
  • the holding apparatus is such that when the handle is manipulated in a state where the latch member is in the open position, the latch can be held in the open position automatically. Conversely, the latch member can readily be turned to the open position by hand, whereupon it can be held in this position immediately. Therefore, the apparatus is convenient in that it can be operated very easily even by an operator busily involved in collection and delivery.
  • Figs. 1 through 4 show a first embodiment of the present invention, in which:
  • Figs. 5 through 7 show a second embodiment of the present invention, in which:
  • the basic structural elements of an apparatus according to a first embodiment of the invention illustrated by Figs. 1 through 4 are four members, namely a base 20, a latch member 30 which operates in cooperation with the base 20, and a holding device 40 for holding the latch member 30 in a closed position.
  • Fig. 3 is a sectional view showing a principal portion of the latch holding apparatus.
  • the base 20 is fixedly secured to, e.g., the main body of a double-leafed hinged door 1, by a bolt 22 inserted from the inner side of the main body of the door 1 and passed through the handle 6 at a prescribed position. Tightening is accomplished by a nut 23.
  • the base 20 is rectangular in shape and is provided with a bolt-insertion hole 21 at each of the four corners of the rectangle, as shown in Fig. 4.
  • a pair of left and right handle grips 24 are provided on the top side of the base 20.
  • the handle grips 24 project upwardly by a distance t from the base 20 in such a manner that the handle 6 can be inserted from above.
  • a recess 24a for inserting the handle is formed between the handle grips 24 and the base 20.
  • Fig. 2 is a perspective view of the latch member.
  • the latch member 30 has a transverse dimension that allows it to fit between the pair of left and right handle grips 24, and is attached to the handle grips 24 by a pivot shaft 25.
  • the upper portion of the latch member protrudes upward from the handle grips 24 and has an inwardly directed projection 31 forming a C-shaped recess 32.
  • the handle grips 24 are provided with respective holes 25a for attaching the pivot shaft 25, which is attached to the latch member 30 substantially at the central portion thereof.
  • the latch member 30 turns up and down with the pivot shaft 25 serving as the center of turning motion.
  • the lower portion of the latch member 30 has the shape of a downwardly directed wedge.
  • the holding device 40 is attached to the latch member 30 at a portion thereof below the position of the pivot shaft 25.
  • a hole 42 for mounting the holding device is provided in the lower portion of the latch member 30 below the hole for the pivot shaft 25 serving as the center of turning motion.
  • pins 41 having a hemispherical shape and constituting the holding device 40.
  • the pins 41 are urged outwardly by a compression spring 43 in such a manner that the heads of the pins are fitted alternately into two recesses 41a, 41b provided in each of the handle grips 24 on the inner side thereof below the hole 25a. More specifically, the two recesses 41a, 41b are spaced apart by about 20° and have the same radii with the hole 25a as center.
  • the locking device holds the latch member 30 in the locked position (the position of the solid lines in Fig. 1) or in the unlocked position (the position of the phantom lines in Fig. 1) after the latch is turned.
  • the latch member 30 turns in the locking direction (clockwise in Fig. 1).
  • the holding device 40 also turns so that the pins 41 fit into the recesses 41a, which is on the side of the locking position of the latch member 30. The holding device holds the latch member 30 is this position.
