Abstract

A demountable assembly structure includes a first body, second body, and engaging component. The first body has a first sliding surface and a slide switch recess positioned proximate to the first sliding surface. The second body has a second sliding surface and an engaging channel positioned proximate to the second sliding surface. The engaging channel is opposite the slide switch recess. The engaging component has a slide switch and a resilient element. The resilient element has a basal portion fixedly disposed in the slide switch recess and a resilient engaging arm extended from the basal portion to the engaging channel and engaged inside the engaging channel. The resilient engaging arm has a guide surface opposite the engaging channel. When the first sliding surface slides onto the second sliding surface, the resilient engaging arm gets engaged inside the engaging channel by having the guide surface slid along the engaging channel.

First claim

What is claimed is:

1. A demountable assembly structure, comprising:
a first body having a first sliding surface defining a top of the first body and a slide switch recess positioned proximate to the first sliding surface;
a second body having a second sliding surface defining a bottom of the second body, arranged such that when the second body is stacked on top of the first body with portions of the first sliding surface and the second slide surface in contact, the second sliding surface is slidable relative to the first sliding surface, the second body having an engaging channel positioned proximate to the second sliding surface, the engaging channel being opposite the slide switch recess when the first body and second body are slid to an engaged position;
and an engaging component comprising a slide switch and a resilient element, the resilient element having a basal portion fixedly disposed in the slide switch recess and two resilient engaging arms extended from the basal portion to the engaging channel, the engaging component moveable in the slide switch recess in a direction of force perpendicular to the first and second sliding surfaces between a first position and a second position;
a rail disposed on one of the first sliding surface and the second sliding surface, and a groove corresponding in position to the rail disposed on the other of the first sliding surface and the second sliding surface, the rail arranged to be received in the groove with the first sliding surface and the second sliding surface in contact and configured to allow the second body to slide on the first body in a direction toward the engaging component;
wherein the first body, the second body, the engaging component, and the rail are arranged such that:
when the engaging component is in the second position, the second body is slidable on the first body such that the two resilient engaging arms come into contact with an outer edge of the engaging channel and are first compressed towards each other by the outer edge of the engaging channel in a direction parallel to the first and second sliding surfaces, and when the two resilient engaging arms pass the outer edge of the engaging channel, the two resilient engaging arms are released and engaged inside the engaging channel such that the second body is in the engaged position; and
when the second body is in the engaged position, movement of the slide switch to the first position disengages the two resilient engaging arms from the engaging channel, such that the second body is slidable on the first body.

2. The demountable assembly structure of claim 1 , wherein a limit recess and a bump which correspond in position to each other are disposed between the slide switch and the slide switch recess, with the limit recess extended in the direction of force, wherein the bump restricts movement of the slide switch to within the slide switch recess and in the direction of force.

3. The demountable assembly structure of claim 2 , wherein the limit recess is disposed on the slide switch, and the bump is disposed in the slide switch recess.

4. The demountable assembly structure of claim 1 , wherein a guide protrusion is disposed on each of two sides of the slide switch, and two slide slots corresponding in position to the two guide protrusions are disposed in the slide switch recess.

5. The demountable assembly structure of claim 1 , wherein each of the two resilient engaging arms has a resilient portion extended from the basal portion and an engaging portion formed at an end of the resilient portion, and the outer edge of the engaging channel comprises an engaging protrusion, and when the first body and second body are in the engaged position, the engaging portions are engaged in the engaging channel by the engaging protrusion.

6. The demountable assembly structure of claim 5 , wherein the engaging portion has a guide surface that is facing the engaging protrusion when the second sliding surface of the second body is placed on the first sliding surface of the first body with the engaging channel facing the slide switch recess and before the first body and second body are in the engaged position.

7. The demountable assembly structure of claim 6 , wherein a positioning-related structure is disposed between the basal portion and the slide switch recess such that the two resilient engaging arms are movable into the slide switch recess while the guide surface is facing the slide switch recess.

8. The demountable assembly structure of claim 7 , wherein the positioning-related structure comprises a plurality of positioning holes and a plurality of positioning posts, the positioning holes being disposed on the basal portion, and the positioning posts being disposed in the slide switch recess.

9. The demountable assembly structure of claim 1 , wherein the outer edge of the engaging channel is formed on a surface of the second body perpendicular to the second sliding surface.

10. The demountable assembly structure of claim 9 , wherein the two resilient engaging arms extend above the second sliding surface in the first position and are relatively lower in the first position.

11. A demountable assembly structure, comprising:
a first body having a first sliding surface on a top side thereof and a slide switch recess positioned proximate to the first sliding surface and extending longitudinally along a lateral side thereof;
a second body having a second sliding surface on a bottom side thereof, arranged such that when the second body is stacked on top of the first body with portions of the first sliding surface and the second slide surface in contact, the second sliding surface is slidable relative to the first sliding surface, the second body further having an engaging channel positioned proximate to the second sliding surface and extending longitudinally along a lateral side thereof, the engaging channel being opposite the slide switch recess when the first body and second body are slid to an engaged position; and
an engaging component comprising a slide switch and a resilient element, the slide switch disposed in the slide switch recess, the resilient element having a basal portion fixedly disposed in the slide switch recess and two resilient engaging arms extended from the basal portion, the engaging component moveable in the slide switch recess in a direction of force perpendicular to the first and second sliding surfaces between a first position and a second position;
wherein the first body, the second body, and the engaging component are arranged such that:
when the engaging component is in the second position, the second body is slidable on the first body such that the two resilient engaging arms come into contact with an outer edge of the engaging channel and are first compressed towards each other by the outer edge of the engaging channel in a direction parallel to the first and second sliding surfaces, and when the two resilient engaging arms pass the outer edge of the engaging channel, the two resilient engaging arms are released and engaged inside the engaging channel such that the second body is in the engaged position; and
when the second body is in the engaged position, movement of the slide switch to the first position disengages the two resilient engaging arms from the engaging channel, such that the second body is slidable on the first body.

12. The demountable assembly structure of claim 11 , wherein a limit recess and a bump which correspond in position to each other are disposed between the slide switch and the slide switch recess, with the limit recess extended in the direction of force, wherein the bump restricts movement of the slide switch to within the s
