Abstract
Description
- The present invention relates to an apparatus for restricting rotation of a cylinder lock including an outer cylinder housing and a key operated inner cylinder disposed in the outer cylinder housing, relative to a panel of a vehicle body.
- Japanese Utility Model Application First Publication No. 1-86658 discloses an apparatus for mounting an electronic lock on a panel of a vehicle body. The panel is formed with an opening including a hole defined by a circular peripheral edge of the panel and a radial cutout communicating with the hole. The electronic lock includes a cylindrical portion and a radial projection extending from the cylindrical portion. The cylindrical portion is disposed within the hole with the radial projection inserted into the radial cutout.
- An object of the present invention is to provide an apparatus including a panel with an opening and a cylinder lock disposed within the opening, which is capable of preventing rotation of the cylinder lock relative to the panel without any increase in thickness of the panel or any provision of a reinforcing member.
- According to the present invention, there is provided an apparatus comprising:
a panel formed with an opening including a hole defined by a circular peripheral edge of the panel and a radial cutout communicating with the hole; and
a cylinder lock including an outer cylinder housing, a key operated inner cylinder disposed in the outer cylinder housing, and a radial projection extending from the outer cylinder housing;
the outer cylinder housing being dIsposed within the hole with the radial projection inserted into the radial cutout;
characterized in that the panel has an integral flap partly defining the radial cutout, the integral flap being turnable about a hinge line at which the panel abuts against the radial projection to withstand stress from the radial projection. -
- Fig. 1 is an exploded perspective view of an apparatus of a first embodiment according to the present invention, showing a panel with an opening and a cylinder lock;
- Fig. 2 is a perspective view of the apparatus as viewed from a rear side thereof, showing the cylinder lock received in the opening of the panel;
- Fig. 3 is an enlarged view in part of Fig. 2;
- Fig. 4 is a front elevation of the panel of Fig. 1; and
- Fig. 5 is an enlarged view similar to Fig. 3 but showing a modified cylinder lock.
- Referring now to Fig. 1, an
apparatus 10 according to the present invention includes apanel 12 of a vehicle body and acylinder lock 14. - As shown in Fig. 1, the
panel 12 is formed with anopening 16 including ahole 18 defined by a circular peripheral edge of thepanel 12 and a plurality ofradial cutouts 20 communicating with thehole 18. - As shown in Fig. 1, the
cylinder lock 14 includes a flangedouter cylinder housing 22 and a key operatedinner cylinder 24 disposed in theouter cylinder housing 22. The key operatedinner cylinder 24 with akey slot 26 rotates in theouter cylinder housing 22 when the key operatedinner cylinder 24 is subject to a torque with a proper key. - As seen in Fig. 1, the key operated
inner cylinder 24 is operatively connected to alocking device 28 for locking a movable member such as door or hood, of the vehicle. Thelocking device 28 is so constructed and arranged within the vehicle as to be shiftable between a lock position in which a movement of the movable member is prevented and a release position in which the movement of the movable member is allowed. Thelocking device 28 shifts into the release position in response to rotation of the key operatedinner cylinder 24 in a predetermined direction as indicated by the arrow R of Fig. 1, and into the lock position in response to rotation of the key operatedinner cylinder 24 in a direction reverse to the direction R. - As shown in Figs. 1 and 2, a plurality of
radial projections 30 extend outward from an outer periphery of a front portion of theouter cylinder housing 22 and join with aflange 32 of theouter cylinder housing 22. - As seen in Fig. 2, the
outer cylinder housing 22 is disposed within thehole 18 with theradial projections 30 which are inserted into theradial cutouts 20, respectively. - As best shown in Fig. 3, the
panel 12 has a plurality of triangularintegral flaps 34 partly defining theradial cutouts 20. Each of theintegral flaps 34 is turnable about ahinge line 36 as shown in Fig. 4, at which thepanel 12 abuts against theradial projection 30 to withstand stress from theradial projection 30. - Referring to Fig. 4, a turning motion of the
integral flaps 34 will now be explained. - As shown in Fig. 4, when the
outer cylinder housing 22 is subject to a torque having a magnitude smaller than a predetermined value but stays in place, theradial projection 30 is placed in a stationary position as indicated in thephantom line 38. When theouter cylinder housing 22 is subject to a torque having a magnitude greater than the predetermined value and rotated in the direction R, theradial projection 30 moves into a rotational position as indicated in thesolid line 40. - During the movement of the
radial projection 30, theintegral flap 34 moves from a first position as indicated in thephantom line 42 of Fig. 4, into a second position as indicated in thesolid line 44 of Fig. 4. - In the
first position 42 as seen in Fig. 4, the theintegral flap 34 has a leadingend 46 remote from thehinge line 36 in abutting engagement with theradial projection 30 to withstand stress from theradial projection 30 when theouter cylinder housing 22 is subject to the torque of the magnitude smaller than the predetermined value. Then, theintegral flap 34 is forced to turn about thehinge line 36 by theradial projection 30 to be placed in the second position. - In the
second position 44 as seen in Fig. 4, theintegral flap 34 is formed with abending edge 48 along thehinge line 36 in abutting engagement with theradial projection 30. Thepanel 12 has an increased structural strength at thebending edge 48, resulting from turning of theintegral flap 34 about thehinge line 36. Thus, thepanel 12 abuts against theradial projection 30 to withstand stress from theradial projection 30 when theouter cylinder housing 24 is subject to the torque of the magnitude greater than the predetermined value. - Unitary rotation of the
outer cylinder housing 22 and the key operatedinner cylinder 24 in the direction R is caused in a predetermined range in thecutout 20 when theouter cylinder housing 22 is subject to the torque of the magnitude greater than the predetermined value. Theintegral flap 34 is so constructed and arranged as to restrict the unitary rotation in the direction R within the predetermined range in which thelocking device 28 connected with the key operatedinner cylinder 24 is kept in the lock position and prevented from shifting into the release position. - Thus, the provision of the
integral flap 34 serves for enhancing structural strength of thepanel 12 which is capable of withstanding stress from theouter cylinder housing 22, without replacement of the panel with a panel having an increased thickness or without using any reinforcing member. By the enhancement, unitary rotation of theouter cylinder housing 22 and the key operatedinner cylinder 24 is restricted so that thelocking device 28 is prevented from shifting into the release position. This simple construction and arrangement of theintegral flap 34 serves for saving a manufacturing cost of the vehicle body. The apparatus of the invention serves for reduction in weight of the vehicle as compared with one utilizing a panel having an increased thickness or a reinforcing member for the enhancement of structural strength of the panel. - Fig. 5 shows a modified cylinder lock of the apparatus according to the present invention, which only differs in provision of a
guide groove 50. Like numerals denote like parts of the apparatus of the aforementioned first embodiment and therefore detailed explanations thereabout are omitted. - As shown in Fig. 5, the
guide groove 50 extends on aface 52 of theradial projection 30 which abuts on the leadingend 46 of theintegral flap 34, in an axial direction of theouter cylinder housing 22. Theguide groove 50 surely receives the leadingend 46 of theintegral flap 34 and serves for a smooth turn of theintegral flap 34 about thehinge line 36.
