Abstract: A security system is provided for locking ski equipment, including skis and ski poles, to each other and to a fixed anchor, the security system being part of the ski pole equipment itself. This is accomplished using a ski pole with a handle which carries a locking mechanism, and a hollow shaft which carries a flexible security line. The locking mechanism includes a double locking system which prevents release of the security line until both a first lock (preferably of the combination type) and an integrated second mechanical lock have both been positively activated by the user. The locks are designed and located for easy access and are positively controlled to release or limit the movement of the security line, preferably without a separate key.

The dial ring has a forwardly facing dial receiving cavity encircled by an integral shielding surround ring formation over a sufficient extent to exclude observation of the dial graduations and numerals laterally and below the dial portion and having an interruption of limited circumferential extent providing a sight opening for observation of the dial graduations and numerals in a restricted observation zone generally above and vertically aligned with the axis of the dial member.

Abstract: A hardware assembly for luggage and the like includes a latch pivotally supported on a luggage case and held in a closed position by engagement between catch elements on the latch and cooperating catch elements on a control member supported for movement along the case, the control member being biased in a direction to engage the catch elements. A pivoted manual actuator associated with the latch engages the control member and is capable of moving the control member in a direction to disengage the catch elements to allow the latch to be opened, when the manual actuator is operated. The catch elements serve as a safety catch to prevent the latch from being opened until the catch elements are disengaged. The hardware assembly may further include a latching slide member coupled to the latch by a link member for movement with the latch, and for engaging a cooperable latch element on a second part of the case when the latch is in the closed position.

Abstract: A combination lock for attache cases and the like. The lock has a plurality of movable elements for setting a combination for selectively locking the lock. A mask is provided which is spring-biased to a first of two rest positions in which the mask conceals the digits. In the second rest position the mask exposes the digits to view. The mask is disposed to mask or block a clasp element of a lock clasp in one embodiment and in a second it masks a release button for opening the lock.

Abstract: Indicating wheels of a combination lock are normally viewed through respective windows which are displaced from alignment with the wheels when the lock is released. The wheels are then obscured so that the combination to which the lock has been set for release cannot be observed. The windows contain optical lenses.

Abstract: A dial for a combination lock extends through a disc mounted on the housing for supporting the dial. A pair of interchangeable members, one being used at a time, are used in conjunction with the dial. The first interchangeable member is a spacer mounted on the disc between the dial and the disc for spacing the dial from the disc and covering a portion of the disc. The second interchangeable member is a cover mounted over the disc. The cover has a window through which the dial can be seen. The window includes a lens with thin plates therein for directing light from the dial in a certain path so that the dial can only be seen from one position. The cover has members for securing the lens in the window so that it is not easily removed therefrom.

Abstract: A dial type combination lock having a plurality of individual locking units each of which consists of a locking means and a dial means. The locking means has a pair of discs, one of which is a leading disc in which are a plurality of the holes at locations coinciding with the numbers displayed on the number carrying portion of the dial, and the other of which is the locking disc having a locking bolt receiving notch therein and a pin that is to be fit into one of the holes corresponding a designated number. The locking disc of each locking unit is connected with the leading disc thereof by the pin on the locking disc engaging in the hole in the leading disc corresponding with the designated number for the respective locking member and connecting shafts connect all the locking means to the dial means, so that during the operation of the lock, the locking bolt receiving notches in each of the locking discs are individually set in the bolt receiving position.

Abstract: Combination lock for the control of the retraction of a lock latch comprising a multiplicity of notched members each displaceable as a function of a numeral or number in the combination, in order that, upon display of the right combination, the notches are aligned with a device for retracting the latch, characterized in that said device comprises means such that, by acting on a same member for instance a button, in a first phase the rake can be moved towards engagement with the notches then aligned, and in a second phase the driving of the latch in a retraction movement can be ensured.
