Abstract

A device can include a support structure to be supported on a bow and that, through other structures and components, can support a viewing part such as an archery sight. For example, the support structure and a structure movable in an elevation direction can have paired guide surfaces that slide against each other, with opposite sets of guide surfaces having effective spans within a stable range despite a user pressing on one side, as in coarse adjustment. Guide surface shapes can allow only negligible relative movement, as with V-shapes. Gibs can be on guide surfaces, with some gibs adjustable to compensate wear, such as with springs. Also, a structure movable in a windage direction can have tapered bushings around guide pins that extend through them and can receive pressure from a spring-like component such as a spring wave washer. And a removable scope mounting device can have parts allowing adjustment around two axes.

Dependent claims

A device that can be part of archery apparatus that supports viewing parts on bows;

the device comprising:
a support structure that, in use, is supported on a bow;
an elevation structure that, in use, supports a viewing part, the elevation structure being movable in an elevation direction relative to the support structure;
the elevation structure having first and second opposite sides and, in use, receiving pressure in a direction approximately perpendicular to the elevation direction from the first side toward the second side;
and
first and second guide surface sets that are disposed toward the first and second sides of the elevation structure, respectively, and that each include one or more guide surface pairs;
each guide surface pair including a respective guide surface on the support structure and a respective guide surface on the elevation structure;
in use, each pair's respective guide surfaces sliding against each other in the elevation direction;
each of the first and second guide surface sets having a respective effective span across which it is affected when the elevation structure receives pressure from the first side;
the first set's effective span being within a stable range relative to the second set's effective span.

A device that can be part of archery apparatus that supports viewing parts on bows;

the device comprising:
a support structure that, in use, is supported on a bow;
the support structure including:
first and second outward faces that face outward approximately opposite each other;
and
an open space defined in the support structure, extending through the support structure between the first and second outward faces;
an elevation structure that, in use, supports a viewing part, the elevation structure being movable within the open space in an elevation direction relative to the support structure;
and
on the support structure and the elevation structure, first and second guide surface sets that are disposed toward the first and second outward faces of the support structure, respectively, and that each include at least one guide surface pair with a respective guide surface on the support structure and a respective guide surface on the elevation structure;
in use, each pair's respective guide surfaces sliding against each other in the elevation direction;
in at least one of the guide surface pairs, one of the respective guide surfaces having an inward-extending surface and the other having an outward-extending surface, the inward- and outward-extending surfaces departing sufficiently from flat surfaces that, together, they allow only negligible relative movement between the support structure and the elevation structure in directions other than the elevation direction.

A device that can be part of archery apparatus that supports viewing parts on bows;

the device comprising:
a support structure that, in use, is supported on a bow;
and
a windage structure that, in use, supports a viewing part and is movable in a windage direction relative to the support structure;
the device further comprising one or both of:
at least one pin-like guide part that is supported on the support structure;

each of the at least one pin-like guide part extending through a respective one of the guide openings;
at least one of the pin-like guide parts having thereon a respective set of one or more bushing parts that are between the guide part's outer surface and the respective guide opening's inner surface and that have inner surface capable of repeatedly sliding against the guide part's outer surface;
at least one of the bushing parts having tapering diameter in the windage direction;
and
a spring-like component;
the support structure having a guide surface that extends in the windage direction and the windage structure having a facing guide surface that faces the guide surface;
the spring-like component being between the guide surface and the facing guide surface and pressing the windage structure away from the guide surface.
