Description

Mounting 1ock Assembly The present invention relates to a mounting block assembly and, more particularly, to a mounting block which can be adjustably mounted to a post of a clothes rack, flower pot display shelf, posts of a school-chair, or the like.

Mounting blocks used on clothes racks, flower pot display shelves, blackboard shelves or the like are generally adjustably retained in position by means of bolts or similar structures. However, when adjustment is required, it is troublesome for the user to unscrew and rescrew the bolts.

The present invention is intended to provide an improved mounting block assembly which is easy to install and adjust on a post.

The present invention provides a block assembly which is adapted to be adjustably mounted to a post of a clothes rack, flower pot display shelf, school chair, or the like.

The block assembly includes a first piece, a second piece detachably coupled to the first piece and at least one fastening means releasably attached to the coupled assembly of the first and second pieces.

The first piece has a first through hole vertically extending from an upper face to a lower face thereof, a first opening defined at a lateral side thereof, a resilient necking passage section defined between and thus communicating with said first through hole and the first opening, and a first engaging means. The first through hole has a diameter the same as that of the post.

The second piece has a second opening defined at a lateral side thereof, a second through hole having an upper end with a diameter greater than that of the post and taperly inclining from an upper face to a lower face thereof toward the second opening and a second engaging means to engage with the first engaging means such that the first through hole communicates with the second through hole via the necking passage section and a lower end of said second through hole coincides with a lower end of said first through hole, and at least one extending rod fixed to other lateral sides thereof for supporting loads.

The fastening means are provided around the coupled first and second pieces to secure the assembly. The necking section is resilient to allow the post to be forcibly moved between the first and second through holes.

By such an arrangement, when the post is received in the first through hole, the post is retained in position, and when the post is received in the second through hole, the block is slidable along the post.

In accordance with one aspect of the invention, the first comprises two dovetail grooves and the second engaging means comprises two dovetail tongues.

In accordance with another aspect of the invention, a portion of a inner periphery of said first through hole has indents to increase friction between the rod and the inner periphery and to hold the rod more firmly in position.

In accordance with a further aspect of the invention, the at least one fastening means are clips and an outer periphery of the first and second pieces have corresponding number of grooves to receive the clips.

In accordance with a further aspect of the invention, the first and second through holes are perpendicular to each other.

The first and second through holes may have a sectional configuration the same as that of the post to which the block is mounted.

Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings in which; Fig. 1 is an exploded perspective view of a mounting block assembly in accordance with the present invention; Fig. 2 is a perspective view of an assembled mounting block assembly in accordance with the present invention illustrating the block assembly in a status slidable along a post; Fig. 3 is a perspective view of an assembled mounting block assembly in accordance with the present invention illustrating the block assembly in a mounted status; and Fig. 4 is a perspective view of an embodiment of the present invention illustrating the mounting block assembly applied to a school chair.

Referring to the drawings and initially to Fig. 1, a block assembly 100 in accordance with the present invention is adapted to be adjustably mounted to a post 30 of a clothes rack, flower pot display shelf, blackboard shelf, or the like. The block assembly 100 generally includes a first piece 10, a second piece 20 and two clips 40.

The first piece 10 has a first through hole 14 vertically extending from an upper face 18 to a lower face (not labeled) thereof, a first opening 17 defined at a lateral side (not labeled) thereof, a necking passage section 15 defined between and thus communicating with said first through hole 14 and the first opening 17, and two dovetail grooves 12 defined at the lateral side of the first piece 10 as first engaging means. The first through hole 14 has a diameter the same as that of the post 30.

The second piece 20 has a second opening 26 defined at a first lateral side (not labeled) thereof, an extending rod 111 fixed thereto through a first hole 21 defined at a second lateral side opposite to the first lateral side for supporting external loads, a second through hole 24 having an upper end 28 with a diameter greater than that of the post 30 and taperly inclining from an upper face 27 to a lower face (not labeled) thereof toward the second opening 26 and two dovetail tongues 22 formed at the first lateral side of the second piece 20 as second engaging means to slidably engage with the dovetail grooves 12 such that the first through hole 14 communicates with the second through hole 24 via necking passage section 15 and a lower end 25 of said second through hole 24 coincides with a lower end 11 of said first through hole 14.The necking section 15 is resilient to allow the post 30 to be forcibly moved between the first 14 and second 24 through holes.

Channels 13a, 23a and 13b, 23b are defined at lateral sides of the first and second piece except for the lateral sides having openings 17 and 26, respectively, such that as the first and second pieces are coupled into one block, two peripheral channels 13 and 23 are defined around an outer periphery of the coupled block for receiving the two clips 40. A portion of a inner periphery of the first through hole 14 has indentation 16 to cooperate with a corresponding indentation portion 31 on the post 30 for preventing slippage occurring therebetween as the post 30 is received in the first through hole 14.

In use, the post 30 firstly is received in the second through hole 24 and the first piece 10 in turn is coupled to the second piece 20 by engaging the dovetail groves 12 with the dovetail tongues 22 forming a mounting block, then, the C-shaped clip springs 40 are applied to the block and received in the channels 13, 23, as shown in Fig. 2. In this state, the mounting block assembly 100 is slidably adjustable along the post 30. As the block assembly 100 is moved to a desired position, the block assembly 100 is forced to pivot and the post 30 is thereby shifted from the second through hole 24 to the first through hole 14 and received therein, as shown in Fig. 3. In this status, the mounting block assembly 100 is retained in position.

Fig. 4 illustrates the mounting block assemblies 100 in accordance with the present invention are applied to a school chair 50. In this application, one block assembly 100 is used to support a table 51 and two block assemblies 100 are used to support seat supports 55 such that both the table 51 and seat can be adjusted according to a user's height.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
