## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a slide, and more particularly to a combination slide that has a slide body and a pressing rod such that the combination slide may be mounted in different types of staircases.
2. Description of Related Art
Slides are set outdoors in parks, schools or playgrounds for children to play thereon. However, some parents worry about safety of their children playing outside. Therefore, a conventional combination slide has been developed for children to play the with the combination slide indoors. The conventional combination slide may be disassembled into several components for storage.
However, components of the conventional combination slide are connected by complicated manners and therefore disadvantage assembling and disassembling thereof. Furthermore, width of the conventional combination slide is constant and cannot fit all widths of staircases. When the width of the conventional combination slide is less that of a staircase, the conventional combination slide cannot be mounted securely on the staircase and easily slips laterally, which results in safety problems.
To overcome the shortcomings, the present invention provides a combination slide to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide a combination slide that has a slide body and a pressing rod such that the combination slide may be mounted in different types of staircases.
A combination slide has a slide body and two pressing rods. The slide body has a head member, a tail member and multiple connecting members. The head member has a head quick-release engaging element.

The pressing rods 2 are telescopic, are mounted respectively on the head member 10 and the tail member 20 and are capable of pressing the combination slide against the staircase 90. Therefore, the combination slide is mounted securely on the staircase. The pressing rods 2 are mounted respectively through the upper assembling hole 17 and the lower assembling hole 27.
With further reference to FIGS. 8 and 9, each pressing rod 2 has an outer tube 40 and an inner tube 50.
The outer tube 40 has an outside tube portion 401, an intermediate tube portion 402, two abutment rings 43 and a screw 41.
The outside tube portion 401 is hollow and is mounted on one of two opposite sides of the head member 10 or the tail member 20, may be mounted in the upper assembling hole 17 or the lower assembling hole 27 and has a pressing end, a mounting hole 4011 and a pressing pad 45. The mounting hole 4011 is defined in the outside tube portion 401. The pressing pad 45 is mounted on the pressing end and may tightly press against the staircase 90.
The intermediate tube portion 402 is hollow, is mounted on the other side of the head member 10 or the tail member 20, may be mounted in the upper assembling hole 17 or the lower assembling hole 27, is mounted detachably in the mounting hole of the outside tube portion 401 and has a through hole 4021 defined through the intermediate tube portion 402.
The abutment rings 43 are respectively mounted around the outside tube portion 401 and the intermediate tube portion 402 and respectively abut the sides of the head member 10 or the tail member 20.
The screw 41 is mounted securely in the mounting hole 4011 of the outside tube portion 401 and extends in the through hole 4021 of the intermediate tube portion 402.
The inner tube 50 is mounted telescopically in the intermediate tube portion 402 of the outer tube 40 and has a pressing end, a connecting end, a nut 51 and a pressing pad 55. The nut 51 is mounted on the connecting end of the inner tube 50 and is engaged rotatably with the screw 41. The pressing pad 55 is mounted on the pressing end of the inner tube 50 and may tightly press against the staircase 90.
With further reference to FIGS. 5 and 6, a second embodiment of the combination slide in accordance with the present invention is similar to the first embodiment. The head quick-release engaging element 15a of the head member 10a of the second embodiment has multiple Ω-shaped engaging slots 151a. The tail quick-release engaging element 25a of the tail member 20a has multiple Ω-shaped engaging projections 251a. The upper intermediate quick-release engaging element 35 of each connecting member 30 has multiple Ω-shaped engaging projections 351a corresponding to the Ω-shaped engaging slots 151a and multiple Ω-shaped engaging slots 361a corresponding to the Ω-shaped engaging projections 251a, 351a. 
With further reference to FIG. 7, a third embodiment of the combination slide in accordance with the present invention is similar to the first embodiment. However, the head member 10b and the tail member 20b of the third embodiment are implemented without assembling holes. The pressing rods 2 are implemented without abutment rings 43. The pressing pad 45 on the pressing end of the outer tube 40 tightly presses against one side of the head member 10b or the tail member 10b. The pressing tab 55 of the inner tube 50 tightly presses against the staircase 90.
The head member 10, tail member 20 and connecting member 30 may be connected or disconnected quickly through the head quick-release engaging element 15, quick-release engaging element 25, upper intermediate quick-release engaging element 35 and lower intermediate quick-release engaging element 36. Therefore, the combination slide may be assembled or disassembled quickly. Furthermore, pressing rods 2 press the combination slide tightly against the staircase 90, which prevents the combination slide from inadvertently slipping on the staircase 90.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
