Embodiment

In the accompanying drawings, the desk-top tripod of realizing according to the utility model is totally indicated by reference character 1.

Desk-top tripod 1 is the highly about about small desk tripod of 150-200mm of 100-200mm and base diameter (in opening structure), and specific design becomes effectively to support photographing apparatus (not shown) or similar optical apparatus.

Consider these size characteristics, desk-top tripod 1 especially is designed to lightly, uses simply, is easy to carry in pocket or bag, but still reliable and effective aspect its supporting functions.

Desk-top tripod 1 comprises bearing 2 and a plurality of (preferably three) shank 3, bearing 2 has the rough structure of the sphere of removing polar caps, a plurality of shanks 3 are hinged on the bearing 2 at its corresponding first end 3a place and can pivot between the open position of tripod and closed position, in open position, shank 3 moves (referring to Fig. 1) away from each other, in closed position, the close each other mobile (not shown) of shank.At open position, desk-top tripod 1 is ready to effectively support photographing apparatus, and as hereinafter in greater detail, and in closed position, desk-top tripod 1 is suitable for transportation and deposits.

The first axle Y that forms the vertical axis of desk-top tripod 1 passes bearing 2, and shank 3 is roughly parallel to first axle Y when being pivoted to the second closed position of desk-top tripod 1, and when being pivoted to the first open position of desk-top tripod 1, they are with respect to tilt maximum angle between 45 ° to 70 ° of first axle Y.

Ballhead 4 and shank 3 are relative and be installed in pivotally in the bearing 2, and are provided with attachment, and this attachment is outstanding from the open top 2a of bearing 2, and is suitable for photographic equipment is fixed to desk-top tripod 1.

Attachment comprises plate 5 and bolt 6, and photographic equipment is placed on the plate 5, and bolt 6 slave plates 5 respective threaded outstanding and that be suitable for and be arranged on locating the photographing apparatus bottom mesh.

Ballhead 4 parts are contained in the bearing 2, and locking framework 10 is arranged in the bearing 2 that ballhead 5 is optionally locked onto bearing 2, and allow or prevent that ballhead 4 from rotating with respect to bearing 2.

Specifically, locking framework 10 comprises brake component 11, and this brake component 11 is placed on ballhead 4 belows and can moving towards ballhead along first direction Y, thereby ballhead 4 is compressed bearing 2 and with ballhead 4 lockings.

Locking framework 10 also comprises slider 12, and slider 12 is positioned at the opposition side of ballhead 4 with respect to brake component 11 and can moves along the second direction X that intersects with first direction Y and preferably form the horizontal axis of desk-top tripod 1.

Brake component 11 preferably has carrier configuration and a pair of internal side wall 2a in being arranged on bearing 2 forms the bearing that supports ballhead 4.In fact, when desk-top tripod 1 was in its common vertical position, ballhead 4 was shelved on the brake component 11.

As better visible in Fig. 7, slider 12 has fork-shaped structure, and this fork-shaped structure has two jaw 12a and l2b, and these two jaw 12a and l2b extend and at relative this brake component 11 of side place butt of brake component 11 and ballhead 4 along second direction X.

The contact surface 9 that contacts with brake component 11 (contact surface that comprises jaw 12a, l2b) of slider 12 limits the plane that tilts with respect to first direction Y and second direction X, thereby when second direction X moves brake component 11 is moved along first direction Y when slider 12.

Specifically, slider 12 can be mobile between the first operative configuration (referring to Fig. 3 and 4) and the second operative configuration (referring to Fig. 5 and 6) along second direction, in the first operative configuration, thereby brake component 11 locks onto bearing 2 with ballhead 4 pushing and pressing bearings 2 with ballhead 4, in the second operative configuration, brake component 11 does not compress bearing with ballhead 4, thus non-locking ballhead 4 and allow this ballhead freely to rotate with respect to bearing 2.

Be limited to clinoplain on the slider 12 tilt approximately 3 °-10 °, about 4 ° angle preferably.

In this preferred embodiments, brake component 11 can move along first direction Y and the second direction X of the vertical and horizontal axis that forms respectively tripod 1 with slider 12, but is to be understood that and can selects any paired direction, as long as they intersect mutually.

Locking framework 10 also comprises the spring part 13 between bearing 2 and slider 12, thereby slider 12 is pressed against in the first structure.

According to first aspect of the present utility model, the contact surface (9) of spring part 13 and slider (12) is stacked with respect to second direction (X) at least in part.

Preferably, spring part 13 extends between jaw l2a, the l2b that also advantageously is contained in slider 12 and is fitted on the pin 12c that is parallel to jaw 12a and l2b and betwixt extension along second direction X.

Slider 12 has the button 14 that extends to bearing 2 outsides at the opposition side of spring part 13, and spring part 13 can activate to promote slider 12 along second direction X by the user, and thereby is used for slider is moved to the second operative configuration from the first operative configuration.

Bearing 2 also is divided into two separate sections by the equator wall 15 that is approximately perpendicular to first direction Y and supports slider 12: top 16 and bottom 17, accommodate brake component 11, slider 12 and ballhead 4 in the top 16, the first end 3a that accommodates each shank 3 in the bottom 17 rotates to allow it to center on respective axis.

When desk-top tripod 1 was in three shanks near each other its closed position, it can transport and deposit easily.When needing, three shanks 3 pivot and desk-top tripod is opened to its open position around himself rotation axis.

Ballhead 4 locks onto bearing 2 usually, and this is because spring part 13 is pressed to the first operative configuration with slider 12, and this first operative configuration is corresponding to brake component pushing and pressing ballhead 4.

In this structure, photographing apparatus can be attached to ballhead 4 easily, photographing apparatus is placed on the plate 5 also be fixed with bolt 6.

By ballhead 4 is rotated with respect to bearing 2, can regulate easily photographing apparatus with respect to the position of desk-top tripod 1.Thereby this elastic reaction by antagonistic spring spare 13 is pressed button 14 and slider 12 is moved to the second operative configuration is realized towards bearing 2.

Like this, brake component 11 slight reductions are with ballhead 4 releases, and allow it freely to rotate with respect to bearing 2.

The unclamping of button 14 makes slider 12 move to immediately the first operative configuration and locks thus ballhead 4.

Therefore desk-top tripod of the present utility model has realized above-mentioned target and purpose, because it provides reliably and the very compact desk-top tripod with ballhead and locking framework.
