Definitions

• the present invention relates to a heel binding for a skate comprising a lateral support for the heel of a skater's boot and a heel lock mechanism f ⁇ r vertically fixing the heel on the skate, said heel lock mechanism comprising a bracket mounted on the rear portion of the skate, in which a locking member is vertically pivotable and is adapted, in an actuated position, to be in contact with an edge portion on the top of the heel, and in an unactuated position, to be pivoted backwards away from the heel, said locking member being a bifurcated locking member which has a lower arm actuatable by the heel of the skater's boot and an upper heel fixing arm provided with a jaw, a pivoted operating arm 36 being disposed to be resiliently pressed against a cam profile on the rear edge of the locking member by a spring means.
• One purpose of the present invention has been to achieve a new, improved heel binding for skates, which makes it possible to lock automatically the heel portion of the skater's boot to the skate, and to make possible a simplified onlocking or opening of the heel binding.
• the heel binding should have a very compact design, i.e. it should extend a very small distance in the longitudinal direction of the skate, so that the binding can be mounted at the very rear end of the skate .
• a binding of the type described by way of introduction is characterized according to the invention in that the operating arm is pressed against the cam profile via a cam roller, said spring means consisting of a tensile spring which is fixed to the locking member and is disposed to be tensioned by the cam roller when the operating arm is moved backwards, away from the locking member to pivot said locking member away from its heel releasing position.
• said spring means consisting of a tensile spring which is fixed to the locking member and is disposed to be tensioned by the cam roller when the operating arm is moved backwards, away from the locking member to pivot said locking member away from its heel releasing position.
• Fig 1 is a sideview of a heel binding according to the invention in its opened position; Fig 2 shows the binding in its boot heel locking position; and Fig 3 is a view from above of the binding according to the invention.
• the heel binding generally designated 10, according to the present invention, comprises a bracket 14 mounted on the top of the rear end of the bootless skate 12.
• the bracket has a bottom plate 16 and two parallel, spaced lateral supports 18, which extend vertically upwards.
• the lateral supports 18 provide a mount for a bifurcated locking member 20, which is journalled in the supports 18 by means of a pin 22.
• the locking member 20 consists of an upper locking arm 24 and a lower linkage arm 26.
• the upper locking arm 24 has at its front a jaw 28, which is vertically adjustable along a grooved portion of the front of the locking arm 24 and can be fixed in place by means of a screw 30.
• the lower linkage arm 26 has a forwardly directed end portion 32 designed, during locking of the binding 10 to be pressed down by the rear portion of the heel 34 of the skater's boot. When the binding is opened, it is designed to lift the heel 34 upwards.
• the two arms of the locking member 20, i.e. the linkage arm 26 and the locking arm 24, can be limitedly pivotable relative to each other about the pin 22 in order to provide, when the binding 10 is being locked, a certain delay in the closing of the locking arm 24 against the heel 34 relative to the pivot movement of the linkage arm 26, and a preceding pushing back of the locking arm 24 when the binding is being opened.
• An operating arm 36 is pivotably mounted on the bracket 14 via a pivot pin 37, which is mounted in the lower portion of the supports 18 and close to the pin 22 in the longitudinal direction of the skate.
• the operating arm 36 has a U-profile cross section, so that it can receive and enclose the major portion of the locking member 20 between the lateral sides of the U-profile when the binding is in its locked position.
• the operating arm 36 supports at its center portion a cam roller 38, which extends between the lateral sides of the U- profile and is rotatably mounted therein.
• a tensile spring 42 fixed in the upper portion of the locking arm 24 at 40 extends behind the cam roller 38 and is fixed at its other end to the pivot pin 37 of the operating arm 36.
• the tensile spring 42 thus exerts a resilient force on the cam roller 38 so that it will be held in contact with a cam surface 44 on the rear edge of the locking arm 24.
• the cam surface 44 has two depressions 46 and 48, serving as end positions for the cam roller 38. In the opened position of the binding 10 shown in Fig 1, the cam roller 38 rests in the upper end position 48, while, in the closed position of the binding as shown in Fig 2, the cam roller 38 has passed a cam stop 50 and has jumped into the lower end position 46.
• Fig 2 shows a safety catch (not shown in Figs 1 and 3) , which has the shape of a pawl 52, which is spring-biassed towards its locking position shown in Fig 2, where it engages over the upper edge of the locking arm 24 and prevents the operating arm 36 from being pivoted backwards and thus unintentionally opening the binding 10, unless the rear end 54 of the pawl 52 is pushed down to release the operating arm 36.
• the upper end of the operating arm 36 has a depression
• the binding 10 also has a lateral support 58 for the heel 34, which in the embodiment shown consists of two arms 60 and 62 (Fig 3) , the inner ends of which are fixed together with the bracket 14 to the skate 12.
• the obliquely forwardly-outwardly directed distal end of each arm has an upwardly directed support 64 with a slightly flared upper portion to facilitate insertion of the heel 34 between the supports 64.
• the position of the arms 60,62 in the horisontal plane is adjustable to adapt the lateral support means 58 to different heel sizes.
• the lateral support means 58 for the heel 34 can conceivably be made, in another embodiment (not shown) integral with the bracket or another portion of the binding
• the binding 10 functions in the following manner:
• the toe of the boot is first inserted into a front toe support of known design (not shown in the drawing) .
• the heel 34 is then pushed down between the lateral supports 64 of the lateral support means 58.
• the heel thereby presses the linkage arm 26 downwards over its end portion 32, thus pivoting the upper locking arm 34 forwards, i.e. counter clockwise in Fig 1, about the pin 22.
• the cam roller 38 leaves its upper end position 48 passing over the cam crest 50, whereupon the cam roller 38, biassed by the spring 42 jumps into the lower end position depression 46, thus pressing the jaw 28 down against the upper edge of the heel 34.
• the operating arm 36 has a pawl 52, as shown in Fig 2, the point of the pawl 52 will snap into the position engaging the frontside of the locking arm 24, thus preventing the operating arm 36 from pivoting clockwise.
• the operating arm 36 is pressed backwards, either by hand or with an icepike in the depression 56, preceded by release of the pawl 56, if present.
